Definitions
- This invention relates to machines by. which a coating of a fluid substance may be applied to various objects. It is of particular utility in connection with the application of cement to edges of the upper portions of shoes; I
- the purpose of my invention is to improve generally the efliciency and convenience of apparatus of this character.
- a feature of the invention concerns an arrangement permitting a yield of the Worksupport to compensate for varying thlcknesses of work operated upon.
- the support has a plurality of sections situated opposite the surface by which the fluid substance is applied, one of said sections being fixed upon a carrier against movement toward and from the applying surface, and another section being yieldable with respect to the surface.
- Such an organization is especially useful in cementing the edges of uppers of rubber-sole shoes of the tennis or sneaker type.
- a junior or counter element is stitched with its lower edge somewhat spaced from the edge of the upper.
- the work may have portions varying in thickness from the remainder of the surface operated on across the entire width to be coated.
- a feature of the invention consists in making yieldable the carrier for the work-supporting sections.
- the work-support may be moved by the operator underthe control of a lever into active and inactive positions with respect to the applying member, said lever having an arm contacting with different surfaces upon the support in the two positions, and, to relieve the operator of unnecessary effort in holding the support up to effect the coating, another feature consists in so arranging this arm that in the active position it is substantially vertical, whereby the, strain is taken by the fulcrum and little or none transmitted through the lever to the operator.
- a further feature of my invention relates to an organization in which the applying means may be readily removed for inspection or cleaning.
- the applying member or roll with its contacting side members, and preferably with itsflow-controlling peripheral member is mounted upon a support with which they are removable as a unit from the frame of the apparatus.
- the roll is joined to its driving shaft by a freely separable connection which adds nothing to the effort required to disassemble its contents in handling.
- a further feature has reference to the common control of the application of power to the movable work-engaging means and the flow through the delivery passage from the fluid tank to the work. As it may not always be desired to operate these simultaneously, I prefer to include a separable connection so that one only may be moved. I
- connecting means as a clutch, between the advancing and indicatingmeans, this connecting means being controlled by means for moving the advancing means to its effective position.
- the controlling means is variable in its relation to the means controlled.
- the controlling means takes the form of a lever arm, the angle of which may be changed, with a consequent change in the time of actuation of the clutch.

- Fig. 5 is a vertical section on the line 5-5 of F ig.-4;
- Fig. 6 is a transverse sectional detail on the line '6-6 of Fig. 1;
- Fig. 7 is a top plan view for the applying roll
- Figs. 8 and 9 are sectional details taken generally on the lines 8-8 and 9-*-9, respectively, of Fig. 2';
- Fig. 10 shows in perspective the connection between the applying roll and its shaft
- Fig. 11 is an enlarged vertical, transverse section through the applying roll and its more closely associated parts.
- Fig. 12 is an enlarged perspective view of the side wall and slide unit which cooperates with the applying roll.
- the active elements of the machine are mounted upon'a frame 10, at the top of and preferably integral with which is located a tank 12 for the fluid, as cement, which is to be applied to the work.
- This tank delivers to a passage 14 at its extreme left-hand edge, as viewed in Fig 1 of the drawings, an inclined bottom wall 16 directing the cement to this opening.
- the tank is preferably of the support 1 closed by a cover 18 screwed to the upper edge of its wall, this cover having shown at one side a supply opening closed by a plate 20 pivotally mounted and fixed in place by thumb screws 22.
- a conveying and agitating member consisting of inclined blades 24 projecting from opposite sides of a hub 26, this being secured upon the lower extremity of a shaft 28 journaled in a boss 30 depending from the under side of the cover.
- a worm wheel 32 Fast upon the up er end of the shaft 28, above the cover an protected by a housing integral therewith, is a worm wheel 32 meshin with a worm 34 secured to a horizontal shaft 36 rotatable in a continuation of the housing.
- a pulley 38 Carried by the opposite extremity of the shaft 36 is a pulley 38, turning loosely thereon but which may be secured to rotate with the shaft by a jaw or other suitable clutch 40.
- a horizontal shaft 58 having fast upon it a'gear 60 meshing with a pinion 62 secured to the driving sleeve.
- annular flange 64 furnishing a thrust bearing and having across its outer face a projection 66 adapted to enter a slot in a cylindrical boss 68 situated concentric with the axis upon one face of a fluid-applying roll 70.
- a cylindrical projection 72 extending from the projection 66 in the axis of the shaft 58 enters a bore in the middle of the roll, serving to center it.
- the roll is held between side walls 74, 74 of a support 76.
- a shank or projection 78 entering a socket 80 in a vertical wall 82 of the frame situated just at one side of the passage 14 from the tank.
- the shank is securedin the socket by a set screw 84- threaded through the wall of the frame.
- a depression 86 In the upper edge of each of the walls 74 is a depression 86 (Fig. 7) to receive a flange 88 upon a side plate 90 arranged for contact with the corresponding side of the roll and with a wall 74.
- These plates at their lower edges are beveled, converging toward the sides of the roll.
- a fluid-controlling slide or scraper 98 In ways 96 in the upper edges of an upwardly inclined 'portion of the walls 74, and with its inner edge cooperating with the downwardly traveling portion of the periphery of the roll, is a fluid-controlling slide or scraper 98.
- the outer end of the slide has a' flange 100 depending over the end wall of the support and mounted for rotation in this flange is a screw 102, which may be turned by a head 104.
- valve 114 of the plunger type, mounted to reciprocatein a horizontal bore 116 in the frame beneath the bottom of the tank.
- the valve member is beveled upon its upper side at .118, this inclined end serving to cleanly cut the fluid instead of forcing it before the extremity of the valve and tending to press it downwardly upon the applying roll.
- the central portion of the valve plunger is'reduced at 120, being there surrounded by a sleeve 122 of absorbent material, as felt.
- this sleeve is impregnated with a substance tending to repel the cement to prevent its leakage along the plunger.
- erosene is suitable for this purpose, and to introduce a fresh supply for the absorbent material there is at 124 a hole through the frame, communicating with the bore 116.
- Pivoted upon the inner end of the valve is a block 126 arranged to slide in the divided end portionof a lever 128 fulcrumed at 130 upon the frame. This lever moves over an inclinedframe-surface 132, in which are two openings 134, 134 engaged by a latch 136 sliding through the lever and operated by a handle 138.
- a spring 140 forces the end of the latch member against the frame, so that when it is over one of the openings 134 it will enter and lock the lever 138 in either a position in which the valve 114 opens or closes the tank passage 14, and thus permits the fluid to flow to the applyingroll or shuts off its delivery.
- a rod 144 mounted to slide horizontally in the frame. This rod carries at its outer end a fork 146 engaging the belt 54.
- the belt shifter may be moved to carry the belt 54 to either the .fast or loose pulley while the valve 114 remains undisturbed.
- a carrier lever 150 in which is journaled a horizontally extending shaft 152 rotatable from the shaft.58 by equal ratio gears 154.
- a Work-supporting roll 156 At the outer extremity of this shaft 152 is mounted a Work-supporting roll 156.
- This roll has a hub 158 (Fig. 5) clamped against a thrust flange 160 upon the shaft by a nut 162 threaded upon a reduced end portion of the shaft.
- the hub has at its outer end an annular flange forming a disk'164, the inner or right-hand face of which, as viewed in Fig. 1, is preferably in vertical alinement with the corresponding face of the applying roll 70.
- the flange furnishes at its periphery a fixed work-supporting section of the roll 156, considered with relation to a relatively movable section, consisting of a ring 166 equal in diameter to the flange 164, the
- peripheries of the flange and ring being normally alined.
- the ring is held between the vertical face of the flange and a circular late or disk 168 separated from the flange y shouldered spacing rods or studs 170, and secured by screws 172 passing through the disk and being threaded into the flange.
- the edge of the ring gives with the flange a transverse dimension of the supporting roll preferably equal to the full width of the applying roll.
- forked members 174 straddle the spacing rods 170, extending outwardly at each side into engagement with the ring.
- helical compression springs 176 Between the adjacent sides of the members 174, seated in sockets therein, are helical compression springs 176 which balance one another in effect and hold the supporting members outwardly against the rods and the ring carried thereby in its correct position.
- the approach of the work-supporting roll 156 to the applying roll is variably limited by a screw 17 8 threaded into the upper surface of the carrier lever 150 and fixed in its adjusted position by a lock nut 180.
- the head of the screw 178 contacts with a boss upon the overhanging portion of the frame and is adjusted until, when the carrier lever is raised by the mechanism to be hereinafter described, the supporting roll is so related to the applying roll that the two rotating together advance the material between them to receive the fluid coating.
- the roll 156 is normally held yield'ably in its raised position in which the work-feeding movement occurs, by an actuating lever 182 fulcrumed at 184 upon the frame below the carrier lever. Between opposed horizontal walls 186, 186 at the outer end of the lever 182 is a pin 188 extending between separated depending flanges 190, 190 of the lever 150.
- a helical compression spring 196 In a vertical socket 192 below the lower wall 186, supported upon a. screw plug 194 threaded into the bottom of the socket, is a helical compression spring 196 within a thimble 198 which the spring forces against the pin 188, With the lever 182 fixed in its raised position, the spring 196 permits both sections of the work-supporting roll to yield simultaneously with respect to the applying roll.
- lever 182 To hold the lever 182, and consequently the lever 150, raised with the rolls in active cooperation, and to permit it to be lowered to stop-the coating. operation, said lever 182 is governed by an operating lever 199. This is shown as a bell-crank fulcrumed at 200 and having a substantiall yertical arm 202,
- an antifriction roll 204 which may contact with either an approximately horizontalsurface 206 on the under side of the lever 182 or with an adjacent curved depression 208.
- an approximately horizontalsurface 206 on the under side of the lever 182 or with an adjacent curved depression 208.
- a tension spring 214 exerting its effect to hold "the operating lever with the antifriction roll in the depression 208, the
- a bevel pinion 216 fast on the shaft 152 meshes with a bevel gear 218 secured to the upper extremity of a vertical shaft 220 journaled in bearings 222 in the frame.
- Fixed upon the lower end of the shaft 220 is a worm 224 meshing with a worm wheel 226 on a short horizontal shaft 228 rotatable in the frame.
- This driven shaft 228 may be connected with or disconnected from the registering mechanism of a suitable indicator 230 by a clutch 232 actuated by an arm 234 of the lever 182.
- This arm so engages the clutch, that when the roll 204 of the bell-crank lever is in the depres-' sion 208 of the carrier lever, the clutch members are out of engagement and the indicator does not operate while the work-supporting roll islowered and the material to be coated is not being fed.
- the arm 234 causes the engagement of the clutch and the operation of the indicator.
- the indicating mechanism may be so organized that its digit disks 236 will read in inches of length of material coated, or any other convenient terms. To insure the actuation of the indicator' only when the supporting roll is so raised that the coating is being applied, the
- connection between the lever 182 and the indicator is made adjustable.
- the arm 234 as having a pivoted end section 238, upon which section is an upwardly extending tail 240, through an opening in which extends a screw 242 threaded into the lever 234.
- the angular adjustment of the section 238 under the influence ofthe screw 242 is maintained by a set screw oted on a bracket 246 located at the rear of the frame near the level of the shaft 58, an
- yoke 250 having at its outer end a yoke 250.
- a pin or spindle 252 held frictionally in place for ready removal and replacement by an enlarged end 254.
- This end and the pin adjacent thereto is split longitudinally so that it may yieldably and separably engage the opening in the inner arm of the yoke, as is illustrated in Fig. 3 of the drawings.
- head 256 atthe outer end of the pin facilitates its withdrawal by the operator to receive a roll 258 j ournaled upon it, the periphery of this roll preferably being grooved to receive a layer 259 of such adhesive-material as friction tape or hardened cement;
- the operator may swing the cleaning roll 258 from its normal position out of engagement with the applying roll against the periphery of the latter, causing the adhesive material on the cleaning roll to take from the less adhesive metallic surface of the applying roll the hardened material gathered thereon.
- the pin 252 is withdrawn, the roll taken out, and the surface scraped. 'It is then returned to its spindle in the yoke for further use.
- a space 260 partially inclosed by side and upper walls, into which the horizontal agitator shaft 36, the main driving sleeve 49, the work-engaging member shafts 58 and 152 and the indicator shafts 220 and 228 extend, and in which all their toothed and belt gearing is located.
- the closure of this space in the frame is completed by a movable panel 262, hinged at 264 on the projecting portion 51 at the rear of the frame and latched by any convenient device at the front.
- the portion 164 of the applying roll is of such width as to engage and coat the space between the lower edge of the junior and the adjacent edge 'of the upper, while the remainder of the applying surface upon the ring 166 is arranged to yield in the passage of the junior beneath it and to cement this and the rest of the edge of the upper to the total desired width.

Specification of Letters Patent.
Application filed October 23, 1918. Serial No. 259,319.
T 0 all whom it may concern:
Be it known that 1, JOHN W. Cosenovn,
' a citizen of the United States, residing at tain Improvements in boating-Machines, of
which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.
This invention relates to machines by. which a coating of a fluid substance may be applied to various objects. It is of particular utility in connection with the application of cement to edges of the upper portions of shoes; I
The purpose of my invention is to improve generally the efliciency and convenience of apparatus of this character.
A feature of the invention concerns an arrangement permitting a yield of the Worksupport to compensate for varying thlcknesses of work operated upon. For this purpose, the support has a plurality of sections situated opposite the surface by which the fluid substance is applied, one of said sections being fixed upon a carrier against movement toward and from the applying surface, and another section being yieldable with respect to the surface. Such an organization is especially useful in cementing the edges of uppers of rubber-sole shoes of the tennis or sneaker type. In the heel portion of these shoes a junior or counter element is stitched with its lower edge somewhat spaced from the edge of the upper. Preferably, I arrange the fixed section previously mentioned to contact with the projecting edge of the upper, while the yieldable section operates over the junior. By this or-- ganization, a uniform layer of cement is appliedto the margin over both the single layer of the upper material and. the superposed layer of the junior. It allows this work to be done with the junior in place, a much more convenient procedure than that of coating the parts separately.
The work may have portions varying in thickness from the remainder of the surface operated on across the entire width to be coated. To meet this condition, a feature of the invention consists in making yieldable the carrier for the work-supporting sections. Thus, in cementing tennis shoe uppers, when a seam in the work is reached, the fixed and yieldable supporting sections may yieldtogether to facilitate the passage of this thicker portion under the applying member audits even coating'without strain upon the work-engaging members.
The work-support may be moved by the operator underthe control of a lever into active and inactive positions with respect to the applying member, said lever having an arm contacting with different surfaces upon the support in the two positions, and, to relieve the operator of unnecessary effort in holding the support up to effect the coating, another feature consists in so arranging this arm that in the active position it is substantially vertical, whereby the, strain is taken by the fulcrum and little or none transmitted through the lever to the operator.
A further feature of my invention relates to an organization in which the applying means may be readily removed for inspection or cleaning. To this end, the applying member or roll with its contacting side members, and preferably with itsflow-controlling peripheral member, is mounted upon a support with which they are removable as a unit from the frame of the apparatus. To allow this, the roll is joined to its driving shaft by a freely separable connection which adds nothing to the effort required to disassemble its contents in handling.
A further feature has reference to the common control of the application of power to the movable work-engaging means and the flow through the delivery passage from the fluid tank to the work. As it may not always be desired to operate these simultaneously, I prefer to include a separable connection so that one only may be moved. I
have shown a sectional lever connected to a belt shifter for governing the power, and a valve plunger to control the fluid flow, there being a connection to allow the sections to move separately or together.
In apparatus of the character now under consideration, there is a tendency for the fluid contained in the tank to leak back along the valve which controls its delivery to the work. A feature of my invention obviates this difficulty, it providing about the valve a packing of absorbent material impregnated with a substance tending to repel the fluid contents of the tank. Preferably, there is an opening giving an opportunity to supply fresh portions of the repelling substance to the absorbent material.
It is important that the coating fluidin the tank be kept in homogeneous condition throughout so that the application to the work will be uniform, and, when the fluid is thick and the bottom of the tank extends considerably to one side of the discharge opening, it is desirable to employ moving means, so, as the level of the tank contents becomes low, it may be urged toward the opening. It is, however, unnecessary to employ power for constantly mixing and conveying the fluid, and still another feature of this invention lies in means interposed between the source of power and a member movable in the fluid tank for connecting and disconnecting the member from the source, so it may be independent of movement of a work-engaging member driven from the same source. 35
with means for advancing the work to the applying means, a means for in'dicatingthe extent of the work coated. I prefer to actuate this indicating means from the workadvancing means, and, as the latter is but intermittently in effective operation, the indicating means is only at such times under its influence. Herein is shown connecting means, as a clutch, between the advancing and indicatingmeans, this connecting means being controlled by means for moving the advancing means to its effective position. To insure correctness of relation between the time the advancing means becomes effective and the time of actuation of the connecting means, the controlling means is variable in its relation to the means controlled. In thepreferred embodiment of the invention, the controlling means takes the form of a lever arm, the angle of which may be changed, with a consequent change in the time of actuation of the clutch.
Other features will appear-from the following description and claims taken in connection with theaccompanying drawings, in which,

Figs. 8 and 9 are sectional details taken generally on the lines 8-8 and 9-*-9, respectively, of Fig. 2';
Fig. 10 shows in perspective the connection between the applying roll and its shaft;
Fig. 11 is an enlarged vertical, transverse section through the applying roll and its more closely associated parts; and
Fig. 12 is an enlarged perspective view of the side wall and slide unit which cooperates with the applying roll.
The active elements of the machine are mounted upon'a frame 10, at the top of and preferably integral with which is located a tank 12 for the fluid, as cement, which is to be applied to the work. This tank delivers to a passage 14 at its extreme left-hand edge, as viewed in Fig 1 of the drawings, an inclined bottom wall 16 directing the cement to this opening. The tank is preferably of the support 1 closed by a cover 18 screwed to the upper edge of its wall, this cover having shown at one side a supply opening closed by a plate 20 pivotally mounted and fixed in place by thumb screws 22. In close proximity to the bottom wall 16 of the tank operates a conveying and agitating member consisting of inclined blades 24 projecting from opposite sides of a hub 26, this being secured upon the lower extremity of a shaft 28 journaled in a boss 30 depending from the under side of the cover. Fast upon the up er end of the shaft 28, above the cover an protected by a housing integral therewith, is a worm wheel 32 meshin with a worm 34 secured to a horizontal shaft 36 rotatable in a continuation of the housing. Carried by the opposite extremity of the shaft 36 is a pulley 38, turning loosely thereon but which may be secured to rotate with the shaft by a jaw or other suitable clutch 40. This is arranged .to be shifted by a lever 42 upon the outer portion 51 of the frame. Upon this sleeve is a fast pulley 52 connected to an external source of power by a belt 54 passing over guide pulleys 56, 56 rotatable at the bottom of the frame. Adjacent to the pulley 52, turning loosely upon the spindle 50 is a pulley 53. Normally the clutch 40 is disconnected and the agitating blades 24*are at rest. If the operator finds that the coating fluid is not uniform in consistency, or if the level of the tank has become so low that it does not flow freely to the passage 14, the clutch is engaged by turning the lever 42 to the left as viewed in Fig. 6, whereupon the agitator rotates, mixing the fluid or forcing it over the bottom of the tank to the discharge passage.
Journaled near the center of the frame above the main driving shaft is a horizontal shaft 58 having fast upon it a'gear 60 meshing with a pinion 62 secured to the driving sleeve. At the opposite end of the shaft 58 is an annular flange 64 furnishing a thrust bearing and having across its outer face a projection 66 adapted to enter a slot in a cylindrical boss 68 situated concentric with the axis upon one face of a fluid-applying roll 70. A cylindrical projection 72 extending from the projection 66 in the axis of the shaft 58 enters a bore in the middle of the roll, serving to center it. The roll is held between side walls 74, 74 of a support 76. From the exterior of the inner wall 74 is a shank or projection 78 entering a socket 80 in a vertical wall 82 of the frame situated just at one side of the passage 14 from the tank. The shank is securedin the socket by a set screw 84- threaded through the wall of the frame. In the upper edge of each of the walls 74 is a depression 86 (Fig. 7) to receive a flange 88 upon a side plate 90 arranged for contact with the corresponding side of the roll and with a wall 74. These plates at their lower edges are beveled, converging toward the sides of the roll. They are held against the roll with the inner plate forced against the inner wall 74 by a screw 92 threaded through the outer wall and held in its adjusted position by a lock nut 94. The plates 90 prevent the passage of cement from the tank past the sides of the applying roll. In ways 96 in the upper edges of an upwardly inclined 'portion of the walls 74, and with its inner edge cooperating with the downwardly traveling portion of the periphery of the roll, is a fluid-controlling slide or scraper 98. The outer end of the slide has a' flange 100 depending over the end wall of the support and mounted for rotation in this flange is a screw 102, which may be turned by a head 104. It is threaded into the support wall at 106, so when rotated it moves the slide in its ways to vary the distance between its inner edge and the periphcry of the roll, thus governing the amount of fluid which may pass to the work. To hold the slide in its adjusted position, a set screw 108 passes through the flange 100, conintersecting inclined wall. Thus the escape of cement is prevented, except between the periphery of the applying roll and the edge of the slide. It will be seen that the roll and its cooperating members, the side plates and slide, together with their support, furnish a unitar'ystructure which may be removed from the frame by merely loosening the set screw 84, the shaft projections 66 and 72 separating from the cooperating slot and bore in the roll to permit this. In the applying surface of the rolls 70 are depressions 112 to convey more effectively the coating fluid t9 the work.
To control the flow of fluid from the tank 12, there is operating in the passage 14 a valve 114, of the plunger type, mounted to reciprocatein a horizontal bore 116 in the frame beneath the bottom of the tank. At the end, within the passage 14, the valve member is beveled upon its upper side at .118, this inclined end serving to cleanly cut the fluid instead of forcing it before the extremity of the valve and tending to press it downwardly upon the applying roll.' The central portion of the valve plunger is'reduced at 120, being there surrounded by a sleeve 122 of absorbent material, as felt. Preferably, this sleeve is impregnated with a substance tending to repel the cement to prevent its leakage along the plunger. erosene is suitable for this purpose, and to introduce a fresh supply for the absorbent material there is at 124 a hole through the frame, communicating with the bore 116. Pivoted upon the inner end of the valve is a block 126 arranged to slide in the divided end portionof a lever 128 fulcrumed at 130 upon the frame. This lever moves over an inclinedframe-surface 132, in which are two openings 134, 134 engaged by a latch 136 sliding through the lever and operated by a handle 138. A spring 140 forces the end of the latch member against the frame, so that when it is over one of the openings 134 it will enter and lock the lever 138 in either a position in which the valve 114 opens or closes the tank passage 14, and thus permits the fluid to flow to the applyingroll or shuts off its delivery. At the opposite side of the fulcrum of the-lever 128 from the connection to the valve plunger is pivoted at 142 a rod 144 mounted to slide horizontally in the frame. This rod carries at its outer end a fork 146 engaging the belt 54. \Vhen the I prefer to make the lever 128 in two sections, there being an arm- 145 carrying the block 126 and independently pivoted upon the fulcrum of the lever, overlaying the main body to which it may be secured by a pin 147. When the pin is withdrawn from engagement with the main portion of the lever 128, the belt shifter may be moved to carry the belt 54 to either the .fast or loose pulley while the valve 114 remains undisturbed.
Fulcrumed at 148 upon the main frame is a carrier lever 150, in which is journaled a horizontally extending shaft 152 rotatable from the shaft.58 by equal ratio gears 154. At the outer extremity of this shaft 152 is mounted a Work-supporting roll 156. This roll has a hub 158 (Fig. 5) clamped against a thrust flange 160 upon the shaft by a nut 162 threaded upon a reduced end portion of the shaft. The hub has at its outer end an annular flange forming a disk'164, the inner or right-hand face of which, as viewed in Fig. 1, is preferably in vertical alinement with the corresponding face of the applying roll 70. The flange furnishes at its periphery a fixed work-supporting section of the roll 156, considered with relation to a relatively movable section, consisting of a ring 166 equal in diameter to the flange 164, the
peripheries of the flange and ring being normally alined. The ring is held between the vertical face of the flange and a circular late or disk 168 separated from the flange y shouldered spacing rods or studs 170, and secured by screws 172 passing through the disk and being threaded into the flange. The edge of the ring gives with the flange a transverse dimension of the supporting roll preferably equal to the full width of the applying roll. To hold the ring in its normal alinement' with the flange while permitting it to yield radially, forked members 174 straddle the spacing rods 170, extending outwardly at each side into engagement with the ring. Between the adjacent sides of the members 174, seated in sockets therein, are helical compression springs 176 which balance one another in effect and hold the supporting members outwardly against the rods and the ring carried thereby in its correct position.
The approach of the work-supporting roll 156 to the applying roll is variably limited by a screw 17 8 threaded into the upper surface of the carrier lever 150 and fixed in its adjusted position by a lock nut 180. The head of the screw 178 contacts with a boss upon the overhanging portion of the frame and is adjusted until, when the carrier lever is raised by the mechanism to be hereinafter described, the supporting roll is so related to the applying roll that the two rotating together advance the material between them to receive the fluid coating. The roll 156 is normally held yield'ably in its raised position in which the work-feeding movement occurs, by an actuating lever 182 fulcrumed at 184 upon the frame below the carrier lever. Between opposed horizontal walls 186, 186 at the outer end of the lever 182 is a pin 188 extending between separated depending flanges 190, 190 of the lever 150.,
In a vertical socket 192 below the lower wall 186, supported upon a. screw plug 194 threaded into the bottom of the socket, is a helical compression spring 196 within a thimble 198 which the spring forces against the pin 188, With the lever 182 fixed in its raised position, the spring 196 permits both sections of the work-supporting roll to yield simultaneously with respect to the applying roll. When a projection upon the work,
with which both the supporting edges of the.
roll portions 164 and 166 contact, passes between the rolls, this yield against the spring 196 will cause a uniform application of the coating and will prevent strain upon the. work-engaging members.
To hold the lever 182, and consequently the lever 150, raised with the rolls in active cooperation, and to permit it to be lowered to stop-the coating. operation, said lever 182 is governed by an operating lever 199. This is shown as a bell-crank fulcrumed at 200 and having a substantiall yertical arm 202,
at the upper end of'whlch is an antifriction roll 204, which may contact with either an approximately horizontalsurface 206 on the under side of the lever 182 or with an adjacent curved depression 208. At the opposite sides of the surface 206 and depression 208 are walls 210, 210 against which the roll204 may rest to limit its movement. Between a substantially horizontal arm 212 of the bell-crank lever and the frame extends a tension spring 214 exerting its effect to hold "the operating lever with the antifriction roll in the depression 208, the
the applying roll. It is to be observed, that when the elements are in the relation just described, the thrustvupon the arm 202 of operator, and little effort is required to hold the machine in its operating position, other than that necessary to overcome the tension of the spring 214. As the pull upon the rod 207 is relaxed, the spring returns the roll 204 to the depression 208 so that the levers 182 and 150 are lowered and the worksupporting roll separated from the applying roll to stop the advance of the material. When the coating is being applied, its location upon the material is determined by an edge gage 213 fixed to the arm 150 and having a vertical wall for contact with the material adjacent to the edge of the section 164 of the work-supporting roll. I have shown mounted upon the gage a pin 215 providing a guide below which the operator may introduce the work and thus avoid catching it between the rolls and the upper edge of the gage, which might cause it to be mutilated. It will be evident that the space throug which the work is advanced in the coating operation, and therefore the length of the surface coated, the width remaining the same for the particular applying roll, Wlll I depend upon the circumference of the supporting roll and the number of times it rotates. Consequently, by connecting properly designed indicating mechanism to the shaft 152, I am able to determine the amount of work treated. A bevel pinion 216 fast on the shaft 152 meshes with a bevel gear 218 secured to the upper extremity of a vertical shaft 220 journaled in bearings 222 in the frame. Fixed upon the lower end of the shaft 220 is a worm 224 meshing with a worm wheel 226 on a short horizontal shaft 228 rotatable in the frame. This driven shaft 228 may be connected with or disconnected from the registering mechanism of a suitable indicator 230 by a clutch 232 actuated by an arm 234 of the lever 182. This arm so engages the clutch, that when the roll 204 of the bell-crank lever is in the depres-' sion 208 of the carrier lever, the clutch members are out of engagement and the indicator does not operate while the work-supporting roll islowered and the material to be coated is not being fed. When, however, the roll 204 is brought beneath the surface 206 to start the feed of material, the arm 234 causes the engagement of the clutch and the operation of the indicator. The indicating mechanism may be so organized that its digit disks 236 will read in inches of length of material coated, or any other convenient terms. To insure the actuation of the indicator' only when the supporting roll is so raised that the coating is being applied, the
connection between the lever 182 and the indicator is made adjustable. I have here illustrated the arm 234 as having a pivoted end section 238, upon which section is an upwardly extending tail 240, through an opening in which extends a screw 242 threaded into the lever 234. The angular adjustment of the section 238 under the influence ofthe screw 242 is maintained by a set screw oted on a bracket 246 located at the rear of the frame near the level of the shaft 58, an
When the applying roll becomes clogged with the fluid from the tank 12, the operator may swing the cleaning roll 258 from its normal position out of engagement with the applying roll against the periphery of the latter, causing the adhesive material on the cleaning roll to take from the less adhesive metallic surface of the applying roll the hardened material gathered thereon. When the operator wishes to remove the accumulation from the cleaning roll, the pin 252 is withdrawn, the roll taken out, and the surface scraped. 'It is then returned to its spindle in the yoke for further use.
It should be noted that at the rear of the main frame is a space 260 partially inclosed by side and upper walls, into which the horizontal agitator shaft 36, the main driving sleeve 49, the work-engaging member shafts 58 and 152 and the indicator shafts 220 and 228 extend, and in which all their toothed and belt gearing is located. The closure of this space in the frame is completed by a movable panel 262, hinged at 264 on the projecting portion 51 at the rear of the frame and latched by any convenient device at the front. By this arrangement, all the moving parts of the machine which it would ordinarily be necessary to protect by special guards are covered, and an exceedingly neat and .compact arrangement obtained. 1 j
' In considering the general operation of the machine, it may be assumed that the upperof a tennis shoe, having a junior attached to the inside of theirear portion, is being cemented. The roll 204 of the operating lever 199 being in the depression 208 of the actuating lever 182, the work-supporting roll 156 is lowered from coopera-v tion with the applying roll. 70 and the Indicator 230 is not registering. The operator, after opening the valve 114 and 'shifting the belt 54 to the tight pulley 52 by the lever 128, places the work upon the supporting roll beneath-the pin 215 with its bottom edge against the gage 213. The portion 164 of the applying roll is of such width as to engage and coat the space between the lower edge of the junior and the adjacent edge 'of the upper, while the remainder of the applying surface upon the ring 166 is arranged to yield in the passage of the junior beneath it and to cement this and the rest of the edge of the upper to the total desired width. With the work thus positioned, the operator draws down the rod 207 to raise the carrier lever and work-supporting roll, as has already been described. Thls forces the work against the cement-applying roll, causing it to be advanced by the rotation of this and the supporting roll and the cement applied to said work by the pockets in the periphery of the applying roll. As the work advances,the indicator 230, being now driven by the clutch, registers the length cemented, so if the machine is leased to the user an appropriate charge may be made. When the entire edge of the work has passed beneath the applying roll, the operator permits the.
