Edward VI Surpremui RQQ United States Patent ice ABSTRACT OF THE DISCLOSURE A bow forming apparatushas a stationary housing and a ribbonholding and transporting carriage mounted on the housing for linear, reciprocating travel with respect to the housing between first and second stop positions. The housing and carriage have interacting, generally planarlfacing surfaces which cooperate to fold the ribbon into a bow configuration 'as the carriage travels from the first to the second stop position. A ribbon feeding device located adjacent the first stop position feeds a predetermined length of ribbon across the path of travel of the carriage. The ribbon feeding device is actuated by the carriage as it travels toward the second stop position. Thus another length of ribbon is in position to be picked up by the carriage on its return to the first stop position. A fastener attaching device is located adjacent the second stop position for securing the folded ribbon in a bow configuration. The apparatus also includes a carriage driving means, a first control means actuated by an operator for initiating movement of the carriage from the first to the second stop position, and a second control means actuated by the fastener attaching means for initiating return movement of the carriage to the first stop position. a

This invention pertains to bowmaking devices and aims 'to provide such a device with co-operating means for securing the parts of each bow together at or near the center which is entirely novel and a definite advance in the 'art. Such co-operating means need not necessarily be employed,"however inasmuch as the parts of each bow may also be secured together at or near the center by 'an independent, portable hand device or means.

FIG. 13 is a schematic wiring diagram of the electrical system of said bowmaking device when the carriage is in the rest position.

Referring to the drawing figures in detail, the reference numeral 1 designates the supporting structure of a conventional type of fastener attaching machine which structure extends down to and rests on the floor; The machine includes the usual attaching punch and die assemblies 2 and 3, respectively, for the attachment of the two parts of a fastener combination to each other and to the interposed work upon the machine being operated for one cycle by the pushing of a foot treadle by the worker operating the machine. The fastener combination parts in this instance are preferably prongedrings and sockets.

The bowmaking device comprises a horizontal table 7 and a depending plate 8 welded thereto at the rear which table and plate unit extend longitudinally along the :front edge of the top 9 of the supporting structure of the fastener machine being secured thereto by means of screws. The table 7 is provided with a longitudinally extending slot 11 therethrough and also a cutout 12 near the front for the die assembly 3 of the fastener attaching machine. A depending plate 13 is welded to the table 7 at the rear thereof in line with the plate -8 which plate 13 is secured to the top 9 of the fastener machine by means of a screw for further securement of the table 7 to said top 9 of the mastener machine. The table 7 is supported at the front by a pair of brackets 16 and 17 welded thereto and to the plate 8.

A pair of bearing blocks 18 and 19 are mounted on the table 7 which blocks 'journally receive opposite shaft portions 21 and 22 of a longitudinal, threaded shaft 20, the axis of which is parallel to said table and the longitudinal center line of the slot 11 therein. A pair of brackets 23 and 24 are also mounted on the table 7, which brackets in turn mount normally open limit switches 25 and 26. Another bracket 27 is secured to the table 7 and mounts a reciprocally, vertically movable spring loaded stop member 28 for a purpose to be brought out below. The coil spring of this member which normally retains the member in the uppermost position is identified by the number 29 while the stop surface of the member is identified by the number 30, the back side of the stop member at the top being a cam surface 31. The lower end of the stop member is provided with a roller 32.

The depending back plate 8 mounts a pivot block 35 (see FIG. 2) upon which a transversely extending lever 36 is pivotally supported by means of a pin 37 extending through the member 35. A bracket 39 having a leg 40 is mounted on the lever 36. A normally closed limit switch 41 is in turn mounted on the leg 40 of the bracket. An angle iron bracket 43 is secured to the end of the supporting structure of the attaching machine through the outstanding flange of which passes a bolt 45 surrounded by a coil spring 46 which bears against the upper surface of the lever 36 and bottom of said flange.

A link assembly 48 is pivotally supported on the inner end of the lever 36 by a cap screw 53. The upper end of the assembly 48 is pivotally connected to a spacing member 55 by means of a cap screw 56 which spacer in turn is fixedly secured to a knife 57 by means of a cap screw 58. The knife is pivotally mounted on a block member 60 by means of a nut and bolt combination 61, the knife being resiliently retained against the block 60 by means of a coil spring 62 positioned on the bolt between the knife and nut. The block 60 is of L shape having a lower forwardly extending portion 64 having in turn an upper horizontal surface across its length. The block 60 is supported on an angle iron bracket 65 which in turn is secured to a plate 66 which is attached to the flat, horizonal top 9 of the attaching machine supporting structure.

A forward, ribbon hold-down member 68 is normally secured to the portion 64 of the block 60 by means of a manually rotatable threaded member 70 threadedly received within the portion 64. The member 68 has a depending portion 71 at the front thereof which rests on the upper surface of the portion 64 of the block 60. The rest of the member 68 is uniformly spaced from the upper surface of the portion 64 for the passage of the ribbon through the slot 75 thus formed between the member 68 and portion 64 of the block 60. The width of the slot is substantially equal to that of the ribbon passing therethrough. A rearward, vertically extended rib 73 of the member 68 is received within a slot of block 60 when such member is secured to the block as can be observed in FIG. 4. The hold-down member 68 can accordingly he slipped upwardly and downwardly within said slot of the member 60 when the member 70 is turned up. The outwardly facing surfaces of the block 60 and member 68 are flush with each other for movement of the knife 57 over these combined surfaces in both the downward and upward directions.

A padded knee lever 76 having a rearward extension 77 is pivotably mounted on a shouldered screw 78 which passes through a portion of the supporting structure of the fastener attaching machine, being retained thereon by a nut. A tubular spacer 79 is existent between the hub portion of the lever 76 and said portion of the machine. A link assembly 81 is pivotably connected at the bottom to the arm 77 of the lever 76 by means of a cap screw and nut combination 85 and at the top to the lever 36 by means of a cap screw and elastic stop nut combination 87. Movement of the lever 76 to the right as seen in FIG. 1 by a persons knee will cause counterclockwise pivotal movement of the lever 36 by downward movement of the link 81. This action applies downward force to the roller 32 of the mechanical stop member 28 which moves said member downwardly against its coil spring 29 for a purpose which will appear hereinafter. Said pivotal movement of the lever 36 also causes the limit switch 41 to swing down and electrically close for a purpose which will be covered hereinafter. Said movement of the lever 36 as the result of the above-mentioned movement of the knee lever 76 will also push up the link 48 to cause counterclockwise pivotable movement of the knife 57 for cutting the ribbon passing thereunder for a purpose which will also be covered below. Upon removal of a persons knee from the lever 76, the coil spring 46 returns the lever 36 and all of the parts operatively connected thereto including the knee lever 76 to their original positions seen in FIGS. 1-4 ready for another movement of the knee lever to the right when desired.

A reciprocally movable carriage generally designated 90 comprises a horizontally disposed plate portion 91 having a pair of coextensive, forwardly extending, parallel fingers 92 and 93 and a transversely, centrally positioned depending post portion 95 which passes through the slot 4 11 in the table 7. The portion is bored for the passage of the threaded portion of the shaft 20 therethrough. A plate member 96 which is threadably secured to a ballcontaining ball nut 97 which rides on the threads of the threaded shaft 20 is secured to the depending portion 95 by means of screws. The member 96 includes a portion 98(see FIG. 2) which extends to one-side beyondthe depending portion 95 and which is provided with a'cam surface 99. The bottom of the portion 95 of the carriage also has a cam surface 101. The depending portion 95 of the carriage 90 is also provided with a horizontal, transversely extending pin 103 extending therethrough which supports rollers 104 and 105 for rolling along the upper surface of the table 7 adjacent the slot 11 during reciprocal movement of the carriage thus to support the carriage together with the engagement thereof by the threaded shaft 20 during such movement and when the carriage is at rest.

The spaced fingers 92 and 93 of the plate portion 91 of the carriage 90 are ground across their lower surfaces back from the front ends thereof to the vertical, diagonal, co-planar stop surfaces 107 and 108. The fingers are also ground down along the inner halves thereof to present a pair of co-planar, horizontally disposed, inner, lower surfaces 110 and 111 extending along the lengths of the fingers for reception along these surfaces of the outer fingers 112 and 113 of a thin sheet metal forked plate member 114, which is fixedly secured to a block support 115 which is in turn secured to the table 7, when the carriage 90 is near and also when it is at its forward position (see FIGS. 7 and 8). The upper surfaces of the fingers 112 and 113, which are co-planar with each other, are somewhat lower than the upper surfaces of the outer parts 118 and 119 of the fingers 92 and 93. The fork member 114 also contains inner fingers 120 and 121 which are bent up with respect to the outer fingers 112 and 113 for a purpose which will appear below. The upper surfaces of the outer parts 118 and 119 of the fingers 92 and 93 are also ground down from their forward ends rearwardly to stop surfaces 123 and 124.

The carriage 90 is further provided with an upper plate member 127 having a transversely centrally located depending portion 128 which is pivotably mounted between a pair of rearwardly extending fingers 129 and 130 of the depending portion 95 of the carriage by means of a pin 131. The forward portion of the depending portion 128 of the plate member 127 is cut back to produce a tapered formation of the lower part of the portion 128 so as to permit forward pivotal movement of such part about the pin 131 until the forward surface of this part abuts against the rear surface of the depending portion 95 of the carriage as seen in FIG. 12. A coil spring 135 is received within bores in the depending portions 95 and 128 of the carriage (see FIG. 1) which spring is compressed in the FIG. 12 tilted condition of the plate 127 and which returns said plate to its normal condition as seen in FIG. 1 when the carriage 90 is moved from the FIG. 12 to the FIG. 1 position. The plate member 127 is provided with a pair of forwardly extending, co-extensive parallel fingers 138 and 139 which are turned downwardly and thickened at the forward ends thereof for a purpose to be brought out below. The plate member 127 also has a rearwardly extending, tapered, downwardly bent terminal portion 142.

The table 7 is also provided with a bracket member near the rear thereof through which a nut and bolt combination 146 extends. A coil spring 147 is positioned on the bolt between the round head thereof and the bracket 145. It should be observed from FIG. 12 that when the carriage 90 moves rearwardly until the depending portion 128 thereof engages the head of the bolt 146 continued rearward movement of the carriage causes clockwise rotation of the plate member 127 about the pin 131 as seen in FIG. 1 until the lower forward surface 133 of the depending portion 128 engages the rear face of the depending portion 95 of the carriage.

A reversible electric motor 150 (see FIG. 3) is secured to the rear, depending portion 152 of a bracket member 151 by means of screws, the upper, horizontal leg of the member 151 in turn being secured to the plate 66. A toothed pulley 154 is mounted on the motor shaft which extends through said portion 152 of the bracket. A similar though smaller toothed pulley 155 is mounted on the rear end portion of the threaded shaft 20 and a timing type, toothed flexible belt 156 extends over both of said pulleys. The operation of the motor 150 in one direction, of course, effects turning of the threaded shaft 20 and consequent movement of the carriage 90 in one direction while a reversal of the direction of operation of said motor will effect rotation of the shaft 20 and consequently movement of the carriage in the opposite direction.

A limit switch 159 is mounted on the end of the supporting structure of the attaching machine (see FIG. 2) which switch has a roller 160 which rides on the hub 162 of a hand wheel 163 on the end of the shaft 164 of the fastener attaching machin which shaft turns whenever the machine is being operated. A button head socket cap screw 165 is received within the hub 162 to trip the limit switch 159 upon movement of the head portion thereof under the roller 160 of the switch during rotation of the machine shaft 164.

A ribbon feeding mechanism generally designated 167 comprises a bracket 168 mounted on the plate 66 which supports a reel 169 of colored ribbon on a headed shaft 170 extending through the vertical flange of the bracket 168. The reel 169 is resiliently biased against a spool spacer or washer member 171 by means of a coil spring 172 which is interposed between a collar 173, retained on the shaft by a hand actuated set screw 174, and a washer 175. The ribbon 177 passes through a guide member 178 secured to a block member 180- which is mounted to the plate 66. The block 180 contains bearing means for the shafts of the wheels 181 through 183. The wheels 181 and 183 have rubber peripheral portions which together with the ribbon passing thereover are received between the opposite (see FIG. 2) flanges of the center wheel or pulley 182.

An electric gear motor 184 is mounted on the plate 66 through a bracket 185, a one revolution clutch 187 being mounted on the motor shaft after the gearing thereof through an adaptor. The shaft 189 upon which the wheel 182 is mounted is connected to the clutch 187 for the driving of said wheel by the motor 184 when a projecting dog 188 and the portion 189 of the clutch from which it extends, which are normally held against rotation with the rest of the clutch by a detent 190, are permitted to rotate with the rest of the clutch by removal of the detent from engagement with the dog 188. The detent is part of a lever 191 which extends upwardly from and is pinned to a yoke 192 and a link 193 which latter is pinned to the armature portion of a solenoid 194. The lever 191 continues upwardly to terminate as a handle 195. A coil spring 196 attached between a plate 197 which is welded to the bracket 185 and the pin 198 normally retains the lever 191 together with the link 1'93 and the solenoid armature in a forward direction so that the detent 190 is engaged by the dog 188 of the clutch.

The solenoid 194 is secured to the plate member 66, a spacer 199 supporting the same at the proper height. The yoke 192 is secured to the spacer 199. Energization of the solenoid 194 will, of course, pull the armature and attached link 193 and the lever 191 to the right as seen in FIG. 2 thus to remove the detent or stop 190 from under the dog 188 of the one revolution clutch 187 to permit the clutch to drive the shaft 189 and consequently the wheel 182 and through it and the ribbon the wheels 181 and 183 to draw the ribbon from the reel 169 and feed it past the knife 57. The movement of the wheel 182 will, of course, be in a clockwise direction as seen in FIG. 2. The solenoid 194 is only energized sufliciently long by the closing of the switch 25 by the passage of the portion 98 of the member 96 of the carriage 90' thereover during movement of the carriage in a forward direction to withdraw the detent 190 from the dog 188 after which the spring 196 returns the members 191 and 193 to their normal positions to stop said dog upon the completion of one revolution thereof to disengage the clutch and prevent any further driving of the wheel 182 and feeding of the ribbon. The gearing of the gear motor 184 together with the diameter of the wheel 182 is such as to move a predetermined amount of ribbon in the forward direction before stopping thereof so that when the knife 57 is moved upon actuation of the knee lever 76 to the right as seen in FIG. 1 a predetermined length of ribbon will be cut off from the rest of the ribbon in the feeding mechanism and on the reel 169.

After the ribbon 177 leaves the wheels 182 and 183 it passes over a horizontal portion 201 of a sheet metal member 202 which is secured to the front face of the block 180 by screws. The ribbon next passes through the slot 75 between the members and 68, under the normally raised knife 57, and therethrough a guide block 203, more particularly, through a horizontally disposed slot 204 therein which is open along the front thereof but normally covered by the depending leg 205 of a hinge 206 secured to the block 203 through the upper, horizontal leg of the hinge which slot is at the back and front thereof. The block 203 is secured to the table 7 by means of a bracket 207.

An L shaped member 209 is mounted for reciprocal vertical movement along the rear face of the guide block 203 by means of a plate 210 and a pair of cap screws 211 passing through the plate and a pair of annular spacers received within a vertical slot 212 in the vertical depending leg of the L shaped member 209. The slot 212 is such as to limit the downward movement of the member 209 to the position as shown in FIG. 10 while permitting this member to move vertically upwardly at least to the extent shown in FIG. 12. The horizontal leg or bar portion 214 of the member 209 has a lower horizontal surface which engages and rides up along the rear, downwardly turned portion 142 of the upper plate 127 of the carriage 90 and also along the normally horizontal upper surface of the member127 during rearward movement of the carriage under said bar portion 214 for a purpose which will be seen presently.

An electrical static eliminator 216 is supported on the 8 block 180 by means of a clip the outer end of which eliminator is adjacent to the ribbon as it passes over the portion 201 of the member 202 to neutralize the static charge that may be present in the ribbon.

A pair of transversely spaced, stationary bow forming assemblies 218 and 219 are supported in elevated positions above the table 7 by means of posts 220 and 221 in the case of the assembly 218; 229 and 230 in the case of the assembly 219. These assemblies comprise horizontal, co-planar plate members 223 and 224 respectively, which are the portions of the assemblies actually supported by and secured to said posts by means of screws as seen in the drawing. These posts are in turn secured to the table 7 by means of screws passing through the table from the underside thereof into said posts.

The plate 223 of the outer assembly 218 has a rearwardly extending narrow portion 225 having an inner, longitudinally extending edge 226 which is parallel to the threaded shaft 20 and also the longitudinal center line of the slot 11. The assembly 218 includes an upper plate member 227 which is screwed to the plate 223 so that the inner, straight edge 228 thereof is slightly spaced from and at least generally parallel to the outer straight edge of the plate member 91 of the carriage when the carriage is in the position shown in FIG. 8, for instance. It is pointed out that said outer edge and also the opposite or inner straight edge of the plate member 91 are generally parallel to the threaded shaft 20, for instance. The plate 227 is adjustable inwardly and outwardly and also, to some extent, angularly, if desired, relative to the plate 223 upon the loosening of its attaching screws and moving of the same relative to these screws by virtue of slots in said plate through which the screws pass. The plate 227 is also provided with an inwardly and forwardly extending straight edge 231 as one progresses forwardly from the rear end thereofthe rear limit of which edge 231 is preferably over the edge 26 of the plate 223.

The assembly 218 is further provided with a sheet metal member 232 which is bolted on top of the rear portion 225 of the plate 223. The manner 232 has a generally U shape rear portion 233 with the rear leg extending further down than the forward leg as seen in FIG. 1. An L shape sheet metal member 234 is welded along its upper horizontal leg to the underside of the member 232 so that its other leg 235 depends adjacent said U shape portion of the member 232 in a longitudinally etxending fashion in the position as shown in FIG. 3. The U shape pocket portion 233 is located opposite the slot 204 in the guide block 203 so as to receive the ribbon 177 therewithin when the ribbon comes from said slot and across the space therebeyond to the U shaped pocket during the operation of the feeding mechanism 167 as can be appreciated from FIG. 10. An L shaped bracket 236 is secured to the table 7 with the vertical leg thereof extending parallel to the threaded shaft 20 and also opposite the slot 204 of the guide block 203. This leg is positioned somewhat out wardly of the inward edge of the U shaped pocket and terminates at the top just short of said pocket. The purpose of the bracket 236 is to cause the ribbon 177 to bend down rather sharply as the same is fed out of the slot 204 and across the space between the same and the pocket 233. The vertical leg of the bracket 236 together with said pocket 233 act to receive and retain the forward portion of the ribbon both during the feeding thereof and also when the movement of the ribbon has stopped for a purpose which will appear hereinafter. FIG. 10 shows the condition of the ribbon 177 when received by the pocket 233 and the vertical leg of the bracket 236.

The plate member 223 is provided on the underside thereof adjacent the inner longitudinal edge 238 of the same with a downwardly extending flat pad portion 239 having a lower, fiat, horizontal surface extending along its length. This pad portion terminates at the front in a slightly forwardly and inwardly extending, vertical, straight edge 240 for a purpose which will be brought out below. The plate 223 is also provided with an upwardly extending fiat pad portion 241 which terminates at its rear in a rearwardly inwardly inclined vertical edge 242 for a purpose also to be brought out hereinafter.

The plate portion 224 of the inner assembly 219 has an inner edge 244 which is preferably parallel to the threaded shaft, for instance. The plate 224 is also provided with a pad 245 on the upper surface thereof which terminates at the rear thereof in a rearwardly, inwardly extending straight edge 246 which is opposite and complementary to the edge 242 of the pad 241. The plate 224 is also provided with a rearward, downwardly inclined portion 248 which has an inwardly forwardly extending straight edge 249 as one progresses forwardly from the rear end of said portion, such edge terminating at the inner edge 244 of the plate 224. The plate 224 is longitudinally split or slotted from the rear end of the portion 248 forwardly at 251 to permit the downward bending of the portion 249 while the back, rearwardly extending portion 252 of the plate 224 continues in the same plane as the rest of the plate except for the portion 249 thereof. The portion 252 is turned up at the end at 253.

A vertical, longitudinally extending plate portion 254 is welded along the top thereof to the inner edge of the portion 252 of the plate 224, the portion 254 passing within the slot 251. The plate portion 254 is also welded to the outer edge of the portion 249 of the plate 224 including the pointed rear end of the portion. A plate portion 255 extends rearwardly from the portion 254 and outwardly away from the longitudinal vertical plane containing the center lines of the threaded shaft 20 and carriage 90. The top edge of the plate portion 255 is welded to the upturned portion 253 of the plate 224, the portion 255 having an upwardly inclined top edge which extends along the underside of said portion 253.

The inner assembly 219 further includes an upper plate member 257 which rests on the upper surface of the plate 224 being secured to said plate by screws. The plate 257 is transversely slotted for the passage of the screws to provide for transverse and also to some extent angular adjustment of said plate relative to the inner longitudinal edge of the plate 91 of the carriage when the latter is in the forward position for instance. The plate 257 is ground up along the inner half thereof relative to said vertical center plane of the screw 20 and carriage inwardly of the line 258 and also at the end forwardly of the line 259 to produce an appreciable space or slot between the inner half of the plate 257 and the upper surface of the plate 224 for a purpose to be brought out hereinafter. The inner straight edge 261 of the plate 257 is slightly spaced from and at least generally parallel to said inner longitudinal edge of the plate 91 of the carriage 90 when the latter is in the forward position for instance. The upper surface of the plate 257 is horizontal and coplanar with the upper surface of the plate 227 of the assembly 218, the upper surface of the plate 224 except for the portion 248 thereof also being horizontal and coplanar with the upper surface of the plate 223 of the assembly 218. The rear inner corner 262 of the plate 257 is bent up for a purpose which will appear presently.

Considering the operation of the bowmaking device and first the bowmaking function thereof and assuming the main switch of the electrical system of the device to be closed and starting with the position of the parts as shown in FIGS. 1-4, movement of the knee lever 76 to the right as seen in FIG. 1 causes downward movement of the forward end of the knife 57 which cuts off the ribbon extending outwardly of the knife from the rest of the ribbon in the device. Such movement of the lever 76 also causes the limit switch 41 to be swung down away from the switch tripping engagement with the bottom of the depending portion 95 of the carriage 90 adjacent the cam 101 thereof to allow the finger of the switch to extend to place the normally closed switch in a closed condition. The closing of this switch 41 completes a circuit through the motor to turn the threaded shaft 20 by means of the pulleys 154 and and the belt 156. Said movement of the lever 76 further causes the mechanical stop member 28 to be moved down to release the carriage. It should be noted that the ribbon is supported across the upper surfaces of the outer finger portions 118 and 119 of the plate member 91 of the carriage 90 and against the stop surfaces 123 and 124 thereof and that the turned down, thickened front end portions of the plate member 127 of the carriage hold the ribbon against said finger portions under the action of the coil spring 135. The ribbon is therefore held or clamped by the carriage 90 in the FIG. 1 position of the latter and as the same moves forwardly after the cutting of the ribbon by the knife 57.

As the carriage 90 moves forwardly the lower part of the outwardly extending portion 98 of the member 96 of the carriage momentarily passes over and depresses the roller and finger of the limit switch 25 which completes a circuit to and thus energizes the solenoid 194. This causes removal of the detent from the clutch dog 188 which allows the one revolution clutch 187 to drive the wheel 182 and through it the rollers 181 and 183 to feed a new and predetermined length of ribbon outwardly of the knife 57 in the manner above explained whereupon 9 one revolution of the clutch having been completed, the detent 190 engages the dog 188 to arrest the feeding of the ribbon.

It is pointed out before going further that the operator removes his knee from the knee lever 76 has soon as the carriage has moved forwardly a short distance, after which removal the spring 46 (see FIG. 2) acting on the lever 36 returns all the parts operatively connected to this lever to the positions thereof shown in FIGS. l-4, that is, in the normal positions thereof. It is also pointed out that the initial movement of the carriage 90 in the forward direction causes the outer part 267 of the cut off piece of ribbon 265 which is received within the U shaped pocket 233 to pull out of the pocket with the assistance of the depending plate portion 235, the upper part of said outer part of the piece of ribbon riding along the inner edge 226 of the plate 223 while the opposite or inner portion of the piece of ribbon pulls out the slot 204 in the guide block 203 through the open front of the slot swinging the free depending leg 205 of the hinge 206 forwardly to permit such pulling out of the piece of ribbon from said slot, said inner portion of the ribbon making contact with the outwardly inclined plate portion 255 when reaching the same during further forward movement of the carriage 90. This inner and depending portion of the piece of ribbon is moved towards the carriage as it engages along the plate portion 255 until the plate portion 254 is reached after which this ribbon portion rides along said plate portion until the point of the downwardly inclined portion 249 of the plate 224 is reached.

When the carriage 90 has moved the ribbon piece 265 to the rear end of the plate 227 and continues forwardly beyond this point, the upper portion of the outer part of the ribbon is caused to be moved inwardly towards the longitudinal center line of the carriage by the riding thereof along the inclined edge 231 of said plate 227. When the ribbon has been moved past the edge 231 said upper portion of the outer part of the ribbon piece then rides along the inner edge 228 of the plate 227. When the ribbon has moved just beyond the inclined edge 231, the outer portion or leg 267 of the ribbon is bent down by the engagement thereof with said edge 228 substantially as shown in FIG. 5 in full lines. Continued forward movement of the carriage then brings a somewhat lower portion of the outer leg of the ribbon into engagement with the inclined edge 264 of the plate 223 which causes an inward folding of outer leg 267 as the leg engages along said edge 264. The phantom lines in FIG. 5 illustrate the outer leg 267 of the ribbon in the course of its riding along the edge 264 and being inwardly folded as a result thereof. When the carriage 90 has moved the ribbon leg 267 beyond the inclined edge 264 such leg has been folded up into a position against the undersurface of the finger 92 of the plate portion 91 of the carriage with the rear edge of the leg either slightly forward of or resting against the stop surface 107 thereof. This leg of the ribbon also is, or subsequently will be, when the end thereof passes within the space between the plates 224 and 257 and the, second leg is folded up, resting against the undersurface of the finger 93 of the plate portion 91 of the carriage with the rear edge of the leg either slightly forward of or resting against the stop surface 108 thereof.

During the folding process of this outer or first leg 267 of the ribbon and subsequent thereto, the upper portion of this leg which has engaged the rear portion 268 of the inner edge 228 of the plate 227 b fore the start of the folding of the leg continues to engage and ride along said edge 228 while the portion of the ribbon leg thereunder is caused to fold or bend inwardly about said portion which rides along said edge 228. This folding or bending together with a similar folding or bending of the inner leg of the ribbon to be covered presently establishes the length of the bow except for projecting ends thereof.

When the inner or second leg 269 of the ribbon piece 265 reaches the rear end of the inclined edge 249 of the plate 224, a mid portion of said leg begins, and increasingly continues, to be turned inwardly towards the aforesaid vertical plane containing axis of the threaded shaft 20, for instance, as the same rides along said edge 249 to produce a folding of this inner or second leg of the ribbon when it reaches the inner surface 244 of the plate 224. The upper part of the inner or second leg 269, after it has ridden along the plate portion 254, engages the under or inner surface of the turned up corner 262 of the plate 257 until the inner edge 261 of the plate is reached, which edge is equivalent to the edge 228 of the plate 227, after which said upper part of the ribbon leg rides along said edge 261 as did the opposite leg ride along the edge 288. Such riding of the upper part of said leg along the surface 261, of course, together with the inward moving of the leg caused by the edge 249 of the plate 224 causes folding or bending of the leg 269 about such portion of the ribbon engaging along said edge 261 thus to establish the length of the bow together with the bending previously mentioned about the portion of the ribbon engaging along the edge 228 of the plate 227.

FIG. 6 illustrates in full lines the inner or second leg 2-69 of the ribbon piece in the course of its riding along the edge 249 of the plate 224 and also the edge 261 of the plate 257 during its folding. The phantom lines in FIG. 6 show this leg of the ribbon completely folded up when the carriage has moved this leg beyond the edge 249 of the plate 224. FIG. 6 also shows the first leg fully folded up' with the end thereof entering the space between the plates 224 and 257. Such ribbon end moves along within this space during the rest of the forward movement. The second leg 269 of the ribbon normally rides along at least the inner part of the under surface of the depending pad portion 239 of the plate member 223.

It will be observed from FIG. 7 that the legs 267 and 269 of the ribbon rearwardly inclined and also cross each other rearwardly of the main portion 270 of the ribbon between the legs as the result of dragging of the two legs along the plates 223, 224 and 257 along which they move after the folding thereof.

As the carriage nears the end of its forward movement, the outer fingers 112 and 1-13 of the stationary fork member 114 ride along the upper surfaces of the inner portions and 111 of the plate 91 of the carriage 90 and under the ribbon portion 270 which extends between the clamping fingers of the carriage 90. The inner and upwardly extending fingers and 121 pass above said portion 270 of the ribbon piece so as to cause said ribbon piece to enter and pass along the two slots or spaces 271 and 272 of said fork member 114 until said ribbon portion reaches the ends of these slots as shown in FIG. 7. Continued forward movement of the carriage 90 into the end limit of movement thereof shown in FIG. 8 causes a certain for-ward bending of the outer portions 273 and 274 of the ribbon portion 270 into engagement with the stop surfaces 242 and 246 of the raised pads 241 and 245 respectively, of the plates 223 and 224 respectively,

Inasmuch as no stop is provided on the carriage 90 for preventing rearward movement of the second leg 269 of the ribbon piece, the forward, inclined edge 240 of the pad 239 of the plate 223 constitutes such a stop surface for said second leg of the ribbon which springs up in front of this edge 240 when this leg moves past the same just slightly before the carriage stops. In the condition of the ribbons shown in FIG. 8 certain stresses are present within the same which if not resisted would cause the ends of the legs 267 and 269 thereof to move rearwardly to relieve such stresses.

The stop surface 240 just mentioned and also the two diagonal, co-planar edges 107 and 108 of the fingers of the carriage plate 91, especially the edge 108, prevent such rearward movement of the legs 267 and 269 of the ribbon when in the stressed condition shown in FIG. 8. Moreover, said edges 240, 107, and 108 are so disposed as to hold said ribbon legs opposite each other and at equal but opposite rearward inclinations. It is particularly important to note that in the FIG. 8 condition of the ribbon the center lines of the legs thereof cross above and below each other along the longitudinal, vertical center plane of the carriage 90 and also below the center line of the portion of the ribbon part 270 between the slots 271 and 272 of the fork member 114 and further also immediately under the centers of the punch and die assemblies 2 and 3 of the fastener attaching machine.

The operator then causes the fastener attaching machine to operate to bring the two parts of a fastener combination together through the three pieces of the bow and a portion of a garment after h'aving placed the portion of the garment over the bow in a desired position so as to cause the bow to be fastened together and to said garment. The garment portion is then moved rearwardly to remove the bow thus formed from the fingers of the fork member 114 after, however, the carriage 90 moves rearwardly (to the right as seen in FIG. 1) sufficiently to remove the fingers 92 and 93 of the carriage 90 from within the loops of the fastened 'bow while the garment portion and attached bow are held against movement.

The carriage 90 was stopped in its forward movement by engagement of the depending portion 95 thereof with the bearing block 18.

During the time the carriage 90 is in the forwardmost position, the electrical current continues to pass through the motor 150 although the armature thereof remains stationary.

Actuation of the fastener attaching machine for one cycle of operation causes the shaft 164 of the machine to rotate which in turn causes the button head 165 to rotate underneath the roller 160 of the limit switch .159 thus closing this normally open switch which effects a reversal of the direction of operation of the electric motor 150 which then causes the carriage 90 to move in a rearward direction. Such rearward movement causes passage of the cam surface 99 of the carriage over the roller of the limit switch 25. However, the solenoid 194 is not energized for a reason which will be brought out hereinafter when reference is made to the wiring diagram.

As previously noted, a new length of ribbon has been automatically fed outwardly of the knife 57 through the guide block 203 and across the space between the same and pocket 233 and bracket 236 (see FIG. Continued rearward movement of the carriage 90 causes the pointed, rear, downwardly inclined end portion 142 of the upper plate member 127 to pass under the ribbon, and also the bar portion 214 of the L shaped member 209 to cause the latter to push the ribbon up such depending ramp portion 142 and then along the top surface of the plate member 127 as the carriage continues to move rearwardly until the ribbon is pushed off the forward ends of the fingers 138 and 139 of the member 127 and onto the forwardly projecting fingers 92 and 93 of the plate member 9.1 therebelow at the very end of the rearward movement of the carriage 90 at which time the upper plate 127 has been tilted upwardly in a manner previously explained. FIG. 11 shows the ribbon being pushed up the ramp portion 142 by the bar portion 214.

Referring now to the wiring diagram of FIG. 13, 280 and 281 are power lines from an alternating current source while 282 is the main line switch. Wires 283 and 284 are continuations of the power lines. The normally closed but held open limit switch 41 is located near the upper end of the wire 284. The static eliminator 216 and ribbon feed motor 184 are connected across the wires 283 and 284 by means of wires as shown and operate as long as the switch 282 is closed. Normally open limit switch 25, normally closed latch relay contacts 285 and a first latch relay coil 286 of a latch relay 287 are connected across the wires 283 and 284 by means of wires 288 through 293. The normally open limit switch .159, normally open latch relay contacts 295, and the first latch relay coil 296 of the latch relay 297 are connected between the wires 283 and 284, wires 298 through 301, 292 and 293. A push button switch 303 is also connected between the wires 283 and 300 by wires as shown. The normally open limit switch 26 and a second latch relay coil 305 are connected between wires 283 and 284 by wires 306 through 308, and wire 283. A second latch relay coil 309 of the latch relay 287 is connected in parallel with the coil 305 by wires as shown. The normally open latch relay contacts 311 of the latch relay 297 and the motor relay coil 312 are connected between the wires 283 and 284 by wires as shown. The reversible carriage moving motor 150 is connected between the wires 283 and 284 for one direction of operation thereof by wires 313 through 315 through the motor relay contacts 316 between the wires 313 and 314, which contacts open when the carriage is in its rest position shown in FIGS. l-3. The motor .150 is connected between the wires 283 and 284 for the opposite direction of rotation thereof by wires 313, 317, 318, and 315; the motor relay contacts 319 which are closed when the carriage 90 is in its rest position. A capacitor 320 of ample size is connected between the wires 314 and 318. To complete the wiring the solenoid 194 is connected between the wires 290 and 284 by wries as shown.

Considering the operation of the bowmaking device with special reference to the wiring diagram of FIG. 13, as above stated closing of the main switch 282 energizes the static eliminator 216 and ribbon feed motor 184. Upon movement of the knee lever 76 to the right, as seen in FIG. 1, which causes a lowering of the limit switch 41 to permit its closing, the motor is energized through the closed relay contacts 319 in one direction of rotation thereof. This causes movement of the carriage 90 in the forward direction. It should, of course be appreciated that the mechanical stop assembly 28 is also moved downwardly out of the way to permit said movement of the carriage forwardly when the knee lever 76 is moved to the right as previously explained.

As the carriage 90 moves forwardly, the normally opened limit switch 25 is closed during the passage of the carriage thereover to cause the current to pass through the closed latch relay contacts 285 of the latch relay 297 and also the relay coil 286 and solenoid 194.

Energization of the solenoid produces the feeding of the ribbon as previously explained. Energization of the latch relay 286 causes closing of the normally open latch relay contacts 295.

After the carriage 90 has moved to its forward location, operation of the fastener attaching machine causes the button head 165 to move under the roller of the normally open limit switch 159 to close the same. Inasmuch as the latch relay contacts 295 are now closed, the current passes through the latch relay coil 296 which causes the opening of the relay contacts 285 and also the closing of the relay contacts 311 to energize the motor relay coil 3,12. The energization of such relay coil causes closing of the motor relay contacts 316 and opening of the contacts 319 to produce reversal of the direction of operations of the motor 150. This reversal of the motor, of course, causes movement of the carriage 90 in the rearward direction.

Movement of the carriage rearwardly with the passage of the cam surface 99 thereof over the roller of the limit switch 25 does not cause a second energization of the solenoid 194 inasmuch as the latch relay contacts 285 of the latch relay 297 are now open. Movement of the carriage 90 rearwardly past the switch 41 does not trip and open the same inasmuch as such switch is a oneway microswitch which trips only when the carriage moves forwardly thereover. When the cam surface 99 of the carriage 90 depresses the roller of the limit switch 26 to close this normally open switch, the consequent flow of current through the latch relay coil 305 causes a closing of the relay contacts 285 and an opening of the relay contacts 311 of the latch relay 297 which latter opening causes deenergization of the motor relay coil 312 to open the motor relay contacts 316 and close the contacts 319 to again reverse the direction of operation of the motor 150, thus returning the motor to is original direction of rotation to move the carriage in a forward direction. Closing of the limit switch 26 also causes current to flow through the coil 309 which effects an opening of the contacts 295 of the latch relay 287. Tripping of the limit switch 4.1 during forward movement of the carriage 90 which opens the switch arrests the operation of the motor 150, thus bringing the movement of the carriage to a stop together with the functioning of the mechanical stop 28, thus completing a cycle of operation of the bowmaking device and returning the carriage 90 to its rest condition shown in FIGS. 1-3.

It is most important to point out that the existence of the contacts 295 of the latch relay 287 with the same being open when the carriage 90 is in its normal rest position permits the fastener attaching machine to be operated independently of the bowmaking device; that is, when no bow has been formed and positioned ready for an attachment therethrough, by the pressing of the foot treadle. The rotation of the machine shaft 164 during the operation of the machine will not afliect the bow making device because of the open contacts 295. The attaching machinemay, of course, be operated as many times as desired without employing the bow making device and, of course, without affecting the same. When it is desired to use said device for the placing of a couple of fasteners with bows on the upper part of a childs sleeping garment, for example, the knee lever 76 is, of course, moved to the right .as previously covered to set the bow making device in operation. Movement of the carriage 90 forwardly over the limit switch 25 effects closing of the contacts 295 as previously covered to permit reversal of-the motor 150 upon the closing of the switch 159 when the fastener attaching machine is operated to secure a bow.

Should it be desired for any reason to return the carriage from the forward position without making a fastener attachment, the push button 303 may be closed which has the same result as the closing of the switch 159.

The lever 195 is moved to the right as seen in FIG. 2 after the carriage 90 has been moved into its forward position and the switch 282 has been opened, to allow the ribbon from .a new reel which has been placed on the reel holder to be placed around and between the wheels 181-183 in the pattern shown in FIG. 2 with the turning of the wheels by hand and also through the slot 75 of the block members 60, 68 after removal and replacement of the latter hold-down member and within the slot 204 of the guide block 203. The lever 195 is then released, the switch 282 closed and the ribbon fed a couple of times by moving said lever to the right and releasing the same. The push button 303 is then pressed to return the carriage 90 to itsnormal rest position shown in FIGS. 1-3. The bowmaking device is now ready to operate for the making of bows in the manner above described.

It is thus seen that a very effective bow making device has been presented in which the bowmaking operations on a piece of ribbon are automatically performed by cooperating stationary and moving surfaces and means as a carriage moves the piece of ribbon in a single, rectilinear direction. An important feature of the present invention is the automatic feeding of .a new length of ribbon, during movement of the carriage in said single rectilinear direction, into a position in which it is picked up by the carriage during the opposite return rectilinear movement thereof, the ribbon also being automatically positioned and clamped within the carriage by the time the same comes to rest at the end of the cycle of operation thereof ready for the start of a new cycle of operation thereof with the automatic cutting off of a predetermined length of the ribbon.

Thus, to restate it briefly a simple rectilinear movement of 'a carriage automatically and simply produces a how which is fastenable to a garment, with the co-operation of stationary surfaces and means while a new length of ribbon is automatically fed into position during this movement of the carriage after which this length of ribbon is automatically picked up and placed in a predetermined clamped position on the carriage on its return rectilinear movement and movement onto its rest position. Such operation is most efiicient and timesaving, permitting the making of many times the number of bows made by any prior device in a given time period and in a far simpler and trouble-free manner without the use of complex manipulating fingers and movement of a ribbon piece around in a rotary direction to a number of stations Where the movement stops each time .and manipulation of the ribbon takes place.

Although the disclosed bowmaking device is used with a fastener attaching machine, other means including independent, portable, hand device or means, of securing the bow together at the center alone or to a garment, for example, may be employed if desired. For instance, the bow may be stitched together or to a garment. Securing the parts of the bows together near the center thereof or to a garment for instance, is necessary for the production of a finished bow which will remain in the bow form upon removal from the bowmaking device. Means such as the fastener attaching machine which co-operates with the bow forming device to secure the bow together at thecenter after being specially prepared by said device for such securing is accordingly in combination with the bowmaking device. Of course, bows formed by said device could also be secured together at the centers thereof, or to a garment, for instance, by the use of a hand device or means.

Fastener combinations may also be secured through the centers of bows alone, which bows in turn may be snapped onto other fastener combinations which have been secured to a garment or other article, should this manner of attachment of the bows to a garment or other article be desired.

Although the bowmaking device has been disclosed as including a static eliminator, such an eliminator is not essential for all ribbon that may be employed and/or for all humidity conditions in the room.

Although a specific construction has been disclosed in the drawing and detailed description, variations and modi- :fications of the same may be had and are in fact had in mind; other embodiments of the inventions are also had in mind. The appended claims therefore should be limited only by their own terms construed liberally.
