MACHINE FOR INSERTING EASTENINGS.

Application filed February 16, 1906. Serial No. 301,473.

TooZZ whom it may concern:

Be it known that I, LOUIS A. CASGRAIN, a citizen of the United States, residing at Beverly, in the county of Essex and Commonwealth of Massachusetts, have invented certain Improvements in Machines for Inserting Fastenings, 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 for inserting in certain classes of stock, more particularly leather, a short length of suitable material, preferably metal, which may be so short as to form merely a slug used'for purposes of ornamentation or resisting wear, or may be of such length as to form a nail or peg used for securing together two or more layers of the stock into which it is inserted. I

As machines embodying this invention may be used to insert devices of the kind described of any desired length, for convenience the term fastening will hereinafter be used generically to designate any device that may be used for any of the purposes named, and wherever the word fastening occurs herein it should be held to include a nail, slug or peg, or all of these, as the context may admit or require.

A general object of the invention is to provide a machine for inserting fastenings which can be operated efliciently at speeds much in excess of those attained by such machines up to the present time.

More particularly the invention aims to provide in a single machine means whereby fastenings may be selected as desired from a plurality of sources of fastening supply for insertion in any one of a number of diflerent predetermined designs. For example, means are provided for causing the insertion of different selections of fastenings alternately or a predetermined number of fastenings of one selection may be inserted alternately with a similar or 'difierent number of another selection or several selections may be inserted in any desired prearranged order, means being provided for causing the design chosen to be repeated automatically if desired until the machine is stopped.

The word selection 1s herein meant to include a single fastening, or a series of fastenings taken from a single source of supply, or a group of fastenings taken simultaneously from two or more sources of supply, and the word predetermined is herein meant to include either one selection of fastenings or more than one selection.

The feature of the invention just described renders it possible, for the first time, to insert automatically a predetermined number of fastenings of one selection and thereafter a predetermined number of another selection, one of the two selections being inserted either wholly in the same row or rows as the other, or wholly or partially in a difl'erent row or rows.

A novel governing device, under control of the operator, is provided for discontinuing the operation of the means which causes the inserting mechanism to operate upon different selections of fastenings, limiting the machine to the continuous insertion of a single fastening or of groups of two or more fastenings which may be inserted in parallel rows.

It is frequently found desirable, particularly when'more than one row is to be inserted, to utilize fastenings which are distinguishable one from the other, as by size, type, quality, etc. Preferably the fastenings used are made distinguishable by being formed of different materials or with dif ferent cross-sections. When this is done, the machine may be used to insert automatically by successive operations different kinds of fastenings in the same row and also at selected intervals to insert simultaneously a fastening, which may be a third kind, in a different row.

The machine is preferably designed to operate upon a plurality of sources of fastening supply whose location with relation to the inserting mechanism is such that fastenings may be automatically presented for insertion in substantially any desired order so as to produce a predetermined design.

A further object of the invention is to provide improved means for feeding the stock in which the fastenings are to be inserted, by the use of a novel, movable engaging means which does not enter the stock. Preferably, the -means for supportingthe stock in proper position relative to Patented Dec. 26, 1911.

' chine for forming these fastenings from continuous lengths or coils of any suitable materlal, as wire, which has previously been given any desired configuration, the

successive fastenings being cut in successionfrom one end of the length or coil.

An important object of the invention is to provide novelmeans for inserting and serving different lengths of. material and for feeding the stock. As here shown, the fastening material is partially inserted, preferably by the severing means, when the desired length is severed and the projecting portion is engaged bya movable member to effect the feeding of the stock, the partially inserted fastening being thereafter driven farther into the stock. The movable work feeding member is preferably carried by a frame swinging in an arc concentric with the main shaft of the machine and having a novel mounting in the machine head with respect to said shaft.

Another object of the invention is to provide in a machine of the kind just described. in which the fastening is formedfrom continuous fastening material by partially inserting by means of the severing mechanism and then severing a length of the material to form a fastening, means for causing the inserting movement of the fastening material to begin While the end which is to form the point of the fastening is at a distance above the surface of the stock, whereby the fastening point strikes the surface of the stock with a considerable impact which facilitates its proper insertion. further advantage is secured by thus causing the wire to be gripped for insertion while its end is above the surface of the stock in that this arrangement permits the edges of the cutters to be held nearly stationary so far as movement lengthwise of the wire is concerned during their gripping movement, and then to acquire a velocity sufficient for the proper insertion of the wire before the point of the wire strikes the surface of the stock, the wire being also enabled in this space to acquire the velocity of the cutters.

The fastening inserting mechanism is preferably carried by a member formed of a plurality of operatively engaging parts which member is connected tothe main shaft and has imparted to it a, continuous reciprocatory movement while the shaft rotates, but said mechanism is normally inoperative as its operatingmechanism is nor-.

mally disengaged therefrom. Means, under control of the operator, is provided for engaging said mechanism, which means acts on one of the moving parts to momentarily Operatively associated with'the mechan v ism for operating the inserting mechanism is means for insuring its engagement notwithstanding the immediate release of the controlling means. This insures the complete insertion of a fastening before the stock can be withdrawn from the machine.

Novel means is shown for supporting the reels containing the wire coils, when continuous lengths of fastening material are used, so that the number of strands used may be increased or diminished at will without disturbing those strands already in use or those to remain in use. This means will not be claimed herein, being made the subject-matter of a divisional application Serial No. 336,152, filed September 25, 1906,

for Letters Patent for improvements in reel supports.

As here shown, the machine is preferably constructed so that the means for presenting the fastenings to the inserting mechanism is continuously actuated, together with the stock feeding mechanism, while the driving shaft continues in operation, and means is provided, under control of the op-. erator, for bringing themeans for rendering the inserting mechanism operative andthe stock supporting means into and outof operative position at the proper moments during the cycles of operation according to the particular design used.

Fig. 16 is a side elevation of Fig. 15 showing in addition a portion of the base.

Referring to the drawings, 2 is a base or standard which supports a head 4 that carries the main shaft 6 provided with fast and loose pulleys 8 and 10, said shaft being mounted in a sleeve or bearing 12 having fastened to its front end a frame 14 in which a cutter-carrier head 16 is movably mounted. The head 16 is movable in frame 14 by any convenient means arranged to impart a relative motion between the two parts, as by a roll 18 that travels in a cam groove 20 in a disk 22 on the main shaft. Fulcrumed in the lower end of said cuttercarrier head are carriers 24 and 24 in which cutters 26 and 26 are mounted, said cutters being held in their carriers by clamping screws 25, 25 and being adapted to be adjusted longitudinally by screws 27 and 27.

To feed'the stock after the insertion of a fastening there is preferably employed a feeding lever 30 pivoted at 31 to a bracket 37 on the head of the machine and provided at its upper end with a roll 32 which travels in the cam groove 20 in disk 22. A link 34,

which is fastened to the lower end of said lever by a clamp 36, is pivotally connected to the frame 14 in which the cutter-carrier head is mounted, so that whenever the lever 3O is oscillated the frame 14 and the mechanism which it carries will be swung laterally for feeding the stock, as hereinafter described. The extent of lateral movement of the frame can be changed to vary the distance which the fastenings are spaced apart by changing the position of clamp 36 on lever 30.

The material from which the fastenings are formed, which for convenience will hereinafter be termed wire, is led down through sliding head 16 and between the cutters, and is preferably inserted as well as severed by said cutters which act as gripping means to seize and force the wire into stock. To this end means are provided for actuating cutters 26 and 26, which are normally inoperative, to bite into the wire slightly to obtain a grip thereon, the. wire then being carried downwardly by the .movement of sliding head 16 and forced into the stock, the cutters during this time being held for movement, when the cutters are again actuated to perform the severing 0peratlon. Means under the control of the operator is provided for causing said outters to become operative or inoperative while the main shaft-continues in operation. Movably mounted in a guideway in the cutter-carrier head 16 is a block 38 the lower end of which is in engagement with the cutter-carriers and communicates motion to them through its movement relative to its sustaining head. A convenient arrangement comprises hook-shaped ends 39, 39 on the block which are adapted to engage lugs on the cutter-carriers, as shown in Fig. 4. Any convenient means may be provided for imparting motion to block 38 in the direction of movement of the sliding head 16. One means is to mount in the sides of block 38 friction plates 40 and 40 which are forced normally into engagement with the walls of the guideway in head 16 by springs 42 and 42, thereby frictionally connecting said block and cutter-carrier head sothat gaging the block from its sustaining head 7 and holding said block stationary while the head with its cutter-carriers moves downwardly, the engagement between the cuttercarriers and the now stationary hook-shaped ends 39, 39 of the block will cause said carriers to rock on their fulcrums, thereby moving the cutters inwardly, to an extent determined by a suitable controlling mechanism, to engage the wire sufficiently to obtain a grip thereon. This operation occupies but an instant of time, and on the 39 of block 38 operates to overcome the force of the means used to hold the block stationary, and consequently the block is carried down with the wire. As the lower sides of the cutters engage plate 106 the controlling mechanism automatically moves to such position that in the continued downward movement of head 16 said cutters may move inwardly still farther until they meet and sever the wire substantially flush with the upper surface of said plate.

The preferred mechanism for controlling the inward movement of the cutters (see Figs. 4 and 5) comprises spring-pressed plungers 44, 44 that are mounted in the head 16, said plungers being borne downwardly upon the inner ends of the cutter carriers, through the force of suitable springs 52, 52, to hold the cutters normally out of engagement with the wire. The

length of the plungers 44, 44 is such that with the head 16 at the top of its stroke their upper ends stand normally a slight distance below a pair of elbow levers 46, 46 which are also mounted in the head and which are provided with engaging faces 47, 47 that contact with sustaining stops, as rollers 50, 50, mounted in the frame 14. This play between the plungers and elbow levers al lows for the initial inward movement of the cutters, caused by the disengagement of block 38 from its sustaining head and the consequent engagement between the lugs on the cutter- carriers 24, 24 and the hookshaped ends 39, 39 of the block. This play also governs the extent of such'movement, for so long as engaging faces 47, 47 contact with stops 50, 50, the lower ends of the elbow levers form a rigid abutment to stop further upward movement of the plungers and consequently inward movement of the cutters. During the greater part of the downward movementof head 16 the upper ends of the plungers are thus engaged by the elbow levers, but when the cutter-carrier head reaches nearly the limit of its downward movement the engaging faces on levers 46, 46 pass out of contact with their sustaining stops, as shown in Fig. 4, so that said levers can move to a position out of engagement with plungers 44, 44 allowing the plungers to yield upwardly against the force of springs 52, 52 in responseto the pressure exerted on their lower ends by cutter-carriers4,24,due to the engagement of the lower sides of the cutters with plate 106. 7 Any suitable mechanism may be employed for disengaging block 38 from cutter-carrier head 16 and for holding said block stationary while the head reciprocates. A convenient arrangement comprises a friction plunger 54 that is movably mounted in a bracket 56 fastened to frame 1.4 by screws 57 and 57. This friction plunger is aranged to be engaged by a presser bar 58 which forces it inwardly into contact with a plate 60 that is interposed between the plunger and block 38, as shown in Fig. 5. Plate 60 is provided with dowel pins 61, shown in dotted lines in Fig. 5, which freely enter recesses formed in block 38, so that said plate and block may move together vertically. Plate 60 is also provided with beveled edges 62 and 62 which are arranged to engage oppositely beveled edges formed on friction plates 40 and 40. Plate 60 has a slight movement between friction plunger 54 and block 38 so that, although normally disengaged therefrom, when the plunger is forced inwardly by the presser bar the plate will be forced against block 38 to clamp said block against a part of the frame 14, the inward movement of plate 60 also causing the beveled edges thereon to engage and move friction plates 40 and 40 away from the walls of the guideway in which block 38 is mounted. When the pressure of bar 58 upon friction plunger 38 and head 16 together, and the beveled edges on said friction plates will cooperate with those on plate 60 for again moving said plate away from block 38.

Vhile bar 58 is in engagement with friction plunger 54, the machine will be operative for inserting fastenings and at the beginning of each downward movement of the cutter-carrier head block 38 will be clamped and held stationary to cause the cutters to engage the wire so that its insertion may be effected. Block 38 is held stationary only for an instant, however, just long enough to enable the cutters to get a grip on the w re, and thereafter the frictional pressure of plunger 54 is overcome by the downward pressure on the hook-shaped ends 39, 39 of block 38 occasioned by the movement of sliding head 16 and said block will move downwardly with the cutter-carrier head and the fastening'will be inserted and sevshown in Fig. 1, and by this means the frictional pressure is overcome and the block and its plate are thereafter moved upwardly continuously with said head. By changing the position of the regulating plate the distance which the block is moved upwardly will be varied and the length of fastenings that are inserted, when a continuous fastening material is used, niay'thus be changed. Whenit is desired to insert long fastenings from one end of a continuous coil, the regulating plate is raised so that it will meet plate 60 sooner and consequently move block. 38 and its hookshaped ends, that are the controlling factor in determining the point on the wire at which the cutters act as gripping jaws, higher up on the wire on the upward movement of the sliding head thereby feeding a greater length when the head again moves'downwardly. When short fastenings are desired said plate is lowered so that. the block will not be moved so high up on the wire before the head again returns downwardly.

It will be noted that even when the his tening-inserting mechanism is adjusted for the insertion of the longest fastenings the movement of block 38 is never suflicient to remove it from the influence of the frictional pressure of plunger 54. This being the case, after the fastening-inserting mechanism has been rendered operative by the ment by the upwardly moving regulating plate 64.

Presser bar 58 is pivoted in any conven-' lent manner at 59 to bracket 56, (see Fig.

5) and at its opposite end is connected to a rod 66 which is confined within a sleeve 68, carrying a hood 69 at its rear end, that is loosely mounted in the head of a machine, as shown in Fig. 3. A coiled spring 70 surrounds said sleeve and at one end engages anut 72 threaded thereon, and at its opposite end engages a washer 74 which bears against a pin 7 6 that projects laterally from the rod 66 through an opening in the sleeve, said spring 70 operating to force said rod rearwardly for causing presser bar 58 to engage friction plunger 54 and hold block 38 stationary.

For relieving the pressure of bar 58 upon the friction plunger to cause the feeding and severing mechanism to become inoperative, an arm 80, having a thick portion 79 and a thin portion 81 (Figs. 2 and 13), is

provided, for moving rod 66 forwardly.

Arm 80 is fastened to a barrel 82 that is mounted on a stud 84 at the rear of the machine. The barrel is provided with two sets of oppositely formed teeth 86, 86 and 87, 87 and is adapted to be rocked for pivotally mounted on a lever 90 which is fulcrumed on a pin 91 in the head of the machine, said lever having a roll 92 that travels in a cam groove 94 formed in the face of pulley 8. During the movement of arm 80 the thin portion 81 acts as a guide to insure the passage of arm 80 into hood- 69. The lever 90 oscillates continuously while the-main shaft revolves and when the tooth 88 of said pawl is in the position shown in Fig. 12, it will engage tooth 86 on said barrel when lever 90 moves downwardly, thereby rotating said barrel and rocking arm 80 in the direction of the arrow in said figure for causing the thickened portion 7 9 of said arm to engage the end of rod 66 and move it forwardly to relieve the pressure of bar 58 upon the friction plunger. After part 79 of arm 80 has been moved into engagement with rod 66 it will remain in this position, to relieve the pressure of bar 58 upon the friction plunger,

until barrel 82 is rocked in the opposite direction carrying arm 80 with it and moving its thick portion 7 9 out of engagement with rod 66 and allowing spring 70 to move the rod rearwardly, the rocking of the barrel in this direction being effected by the pawltooth 89 which engages tooth 87 when lever 90 moves downwardly. The pawl, carrying tooth 89, is moved into operative position when the operator depresses the startin treadle 190, hereinafter described.

hen wire in continuous lengths is used as a fastening material it is preferably supported in reels as shown at 100, 101 and 102, (Fig. 2) and each strand of wire is drawn from the center of its reel down through a checking device 103 and a movable throat block or fastening presenter 104 into. position to be engaged by the cutters. The fastening presenter 104 is preferably mounted within the block 38 which for this purpose is provided with a suitable recess in any convenient manner, as by being made yokeshaped. The checking device is provided with pawls 17 (Fig. 1) which engage the wire and secure it against rearward movement when the cutter-carrier head is moving upwardly. Plate 106 through which the wire is passed in its downward movement which as hereinbefore mentioned is mounted to oscillate with frame 14, constitutes the means for feeding the stock. The feed plate is mounted in the lower end of the cutter-carrier head and is provided with an upwardly projecting bifurcated shank 107 which is held in frictional engagement with the arms of block 38 by a spring clip 108 fastened to said block. The feed plate is herein shown as provided with a plurality of passageways a, b, 0 and at through which the different strands of wire may pass.

When the machine is operative for inserting fastenings the feed plate occupies a position some distance below the lower end of the cutter-carrier head. When the head moves downwardly the feed plate moves downwardly with the head in a direction in axial parallelism with the fastenings and engages the stock before the downward movement is completed, and as there is only a frictional connection between feed plate 106 and block 38 the feed plate will move relatively to the block and will thus be brought into close proximity to the lower end of the cutter-carrier head.

After the wire has been severed by the engagement 'of the lower sides of the cutters with feed plate 106, as previously described, the feeding lever 30 is actuated for moving frame 14 and feed plate 106 laterally transversely of the axis of the fastening, and as a portion of the fastening which has just been formed projects into the passageway in the feed plate the stock into which the fastening is inserted will move laterally with the feed plate, said feed plate moving in an opening formed in the foot plate 5. Cuttercarrier head 16 then moves upwardly and frame 14 moves back to starting position, and at the neXt descent of the cuttercarrier head for inserting another fastening, a solid portion of feed plate 106 engages the fastening which was partially inserted at the previous operation and completes its insertion forcing it into the stock flush with the sur by rod 66 is pivoted at 112 to frame 14, sov

that when rod 66 moves rearwardly for causing the inserting mechanism to become operative the lower end of said dog will be moved into position to be engaged by the feed plate when it starts to move upwardly with the head. The feed plate, however, owing to its frictional engagement with the yoke-shaped block, is first withdrawn from engagement with the partially inserted fastening before it engages said dog. When rod 66 is moved forwardly for causing the fastening inserting mechanism to become inoperative, the lower end of dog 111 will be moved in the opposite direction into inoperative position to permit the feed plate to reciprocate with the cutter-carrier head.

Conveniently located on head 4 isv a bracket or arm 120 (Fig. 2) having at its free end a socket or eye 122 in whichare mounted the supports which in turn carry the usual reels in which are placed the coils of continuous fastening material. These supports comprise hollow standards 124, 126, 128 each having a tapered end 130, and a socket 132 at its other end surrounded by a ball-bearing raceway 134. These standards fit snugly end to end and carry the reels upon the bearings 134. In the side of each standard is an opening 136 through which the end of the coil passes after having engaged a guide 137 secured to the standard and from thence through the standard and socket 122 to the machine. By mounting the reels in this manner the standard of each reel forms a support for the reel above it, so that an extra reel can be added to the machine at any time without providing an additional bracket or support for it. The fastening presenter 104, of the machine herein described, is provided with three passageways 3, 5 and 7 through which strands of oblong, round, and diamondshaped wire 9, 11 and 13 may-pass, said block being adapted to be moved backwardly and forwardly in the yoke-shaped block 38 to carry the different strands of wire into alinement with the cutters. During this movement the presenter 104 is confined in correct position within the block 38 by being splinedthereto, as at 33, which connection forms a convenient guideway between the two parts. The reciprocation of presenter 104 may be so governed that when it is in either its forward or rearward position one or more of the wire strands may be in alinement with the cutters for insertion when the head moves downwardly.

The preferred mechanism for reciprocating the fastening presenter forwardly and backwardly to change automatically from one selection to another selection from the reels forming the sources of fastening sup ply comprises an elbow lever 140 (see dotted lines in Fig. 3) pivoted to the head of the machine and provided at its upper end with a roll 141 that travels in a groove 142 in a pattern cam 143, said lever being provided at its lower end with rack teeth 139 which cooperate with a movable rack-toothed bar 144 mounted in a guideway in an actuator bar 145 that is connected to the presenter 104, and which is movably mounted in the head of the machine. The presenter is provided with an L-shaped piece 153 which engages a slot 152 in the end of the actuator bar, so that the presenter can reciprocate vertically relatively to the actuator bar, but will move horizontally with said bar. In order that the checking device 103, through which the wire strands also pass, may always bear the same relation to presenter block 104, it is connected by a piece 105 to one of the moving parts, as here shown the actuator bar 145.

The pattern cam 143 is mounted on, a shaft 146 provided with a gear 147 that meshes with a worm 148 formed on the main shaft, so that the racktoothed bar will reciprocate continuously while the main shaft is in operation. Although lever 140 and rack-toothed bar 144 have a continuous reciprocatory motion imparted to them, means under control of the operator are provided for so connecting the fastening presenter that it will be affected by either the full reciprocation of the continuously moving parts or motion in one direction only. As here shown two dogs 150 and 151 are pivoted to the actuator bar and are adapted to engage recesses 154. and 155 formed in therack-toothed bar 144 for connecting the two bars together. When both of said dogs are in an operative position and cam groove 142 is properly laid out, the actuator bar will reciprocate in both directions with the movement of the rack-toothed bar, and the presenter block will be moved backwardly and forwardly to present first one selection and then another selection of fastenings in position to be acted upon by the cutters. When dog 151 is inoperative the actuator bar and presenter block will be moved rearwardly by the rack-toothed bar and will remain in this position until dog 151 is again moved into operative position, the rack-toothed bar meanwhile reciprocating back and forth in the guideway in the actuator bar without imparting any movement to said actuator bar, and consequently one selection only of fastenings will be inserted successively. When dog 150 is inoperative the actuator bar and presenter block will be moved forwardly with the racktoothed bar, and a still different selection of fastenings will be inserted successively until dog 150 is again moved into operative engagement with. the continuously-reciproeating rack-toothed bar.

For governing the operative and inoperative positions of the dogs 150 and 151, a controlling or governing device 159 is pivotally connected by a bolt 160 to the side of the machine frame. This device preferably comprises a ring 162 that is adapted to support plungers 163 and 163 that bear upon the dogs 150 and 151 and move them into the recesses 154 and 155 of the rack-toothed bar, said ring having a high portion h and a low portion Z, as shown in Fig. 7. A handle 165 projecting from the controlling device 159 is provided with a spring-pressed detent 166 that engages recesses r r and 7", forward in a stationary part of the head of the machine for preventing accidental movement of said device. WVhen the detent is in engagement with recess 1*, as shown in Fig. 7, the high portion h of the ring will engage both plungers for moving both dogs 150 and 151 into engagement with the reciprocating rack-toothed bar, as shown in Fig. 6, and when the detent is in engagement with recess 1' the ring 162 will be so positioned that its low portion Z will be underneath plunger 163, thereby permitting said plunger to drop down so that the dog 151 can move out of engagement with the reciprocating rack-toothed bar 144, said dogs being forced normally away from said bar by means of the spring 157. hen the detent is in engagement with recess r the low portion Z of ring 162 will be underneath plunger 163 and the high portion h underneath plunger 163, so that the dog 150 will be disengaged and the dog 151 engaged with the rack-toothed bar.

It is thus seen that with a pair of cutters of suflicient width to insert and sever two or more strands of wire simultaneously designs similar to those shown by Figs. 8 and 8 can be readily formed by properly setting the governing device. With three strands of wire and the governing device set as shown in Fig. 6, the design of Fig. 9 is formed. If one of the strands, as that shown as diamond-shaped, be omitted, the design of Fig. 9 is formed, and if the layout of g the actuating cam is changed slightly so that its throw is lessened, the design shown by Fig. 9 is formed. With a pair of cut ters of such a width as enables them to insert and sever only a single fastening at a time, it is readily seen that an actuating cam can be laid out to cause fastenings to be presented for insertion from the various sources of supply in any prearranged order. The designs of Figs. 10 and 10 are examples of this class of work. It is also obvious that with the smaller cutters and a properly laid out cam, designs Similar to those shown in Figs. 10* and 10 can be formed, wherein successive series of fastenings are inserted. Any of the designs of Figs. 10 to 10 can also be formed'when cutters of greater width are used; a single example is shown by Fig. 11. If desired, the various sources of supply may be arranged each to furnish the same kind of fastening, in which case, although fastenings would be inserted in a similar location as before, the designs would have a somewhat different appearance.

Although the manner of forming only a few different designs has been described, obvious the machine is not limited thereto, the production of a substantially limitless number of designs being made possible by using a greater or less number of distin guishable fastenings and varying the time at which the inserting mechanism acts upon the different selections. This may be readily accomplished, as before indicated, by substituting different shaped pattern-cams 143 which, according to their particular design, will vary the period and amplitude or both period and amplitude of the oscillation of the feed lever 140 and consequently correspondingly alter the movements imparted to the threat block or fastening presenter 104.

The horn 170, on which the stock is supported, is connected by a link 171 to one end of a lever 172 pivoted at 173 to the base of the machine, and fastened to the other end of said lever is a rod 174 which is connected to a bifurcated lever 17 5 that straddles lever 90, said bifurcated lever being fulcrumed on pin 91 and being provided with a curved surface 17 6 which is concentric with said fulcrum pin. Between said curved surface and a straight face on the end of lever 90, a roller 178' is adapted to be interposed for locking said levers together, so that when the lever 90 moves downwardly the bifurcated lever 175 will move with it for elevating the horn, to clamp the stock against the foot plate 5. The horn is preferably so mounted that it may be retracted by its own weight. During the time that the fastening inserting mechanism is inoperative the roller 178 is held in its lower or inoperative position, so 1 that the downward movement of continuously moving lever 90 will have no effect upon the bifurcated lever 175. Roller 178 is carried in a yoke on the end of a rod 180 guided in a sleeve 181 projecting from the head of the machine, and is held normally at the upper end of said yoke by aspringpressed plunger 186, said rodbeing provided with a laterally extending pin 182 which is engaged'by the free end of a spring 185 that surrounds barrel 82 which carries arm 80, the other end of said spring being connected to said barrel. Rod 180 is raised with the spring 185 to carry the roller 178 into engagement with the faces on said levers, as above described, and when so engaged the roller moves up and down in the yoke on the upper end of said rod. rod is provided with a stop 183 which engages the sleeve 181 and limits the upward movement of said rod, and for varying the extent of said upward movement the position of said stop on rod 180 can be changed by a micrometer screw 187 on the lower end of the rod.

Arm 80 which actuates rod 66 is provided with a laterally-projecting pin 188, and when the thick portion 79 of said arm is in engagement with said rod for holding the presser bar 58 out of contact with friction plunger 54, pin 188 will engage the free end of spring 185 and move it to depress rod 180' for holding roller 178 out of engagement with levers 90 and 175, as shown in Fig. 12. When the thick portion 7 9 of arm 80 is moved out of engagement with rod 66 spring 185 will raise rod 180 and carry the roller into operative position.

A foot treadle 190 is pivoted to the base of the machine, and fastened to one end of said treadle is a rod 191 which, at its upper end, is provided with inclined faces 192 and 193. These inclined faces cooperate with inclined faces on a block 194 pivoted at 195 to the head of the machine, said block having fastened thereto a leaf spring 196 which is connected at its upper end to the double pawl carried by lever 90, as shown in Figs. 12 and 13. W hen the fastening inserting mechanism is inoperative block 194 and the double pawl will occupy the positions shown in full lines in Fig. 12 or in dotted lines in Fig. 13, pawl tooth 88 having engaged and rocked barrel 82 in the direction for mov ing the thick portion 79 of arm 80 into engagement with rod 66.

\Vhen foot treadle 190 is actuated the inclined face 192 on rod 191 will engage block 194 and turn it into the position shown in full lines in Fig. 13, and the leaf spring on said block will move the double pawl from the dot-ted into the full-line position in said figure, thereby carrying pawl tooth 89 into position so that at the next downward movement of lever 90 said tooth 89 The I will engage teeth 87 and 87 successively on the barrel and move arm 80 in the direction of the arrow in Fig. 13 forcing its thick portion 79 out of engagement with rod 66, said arm remaining in this position during the time that the operator keeps treadle 190 depressed. l/Vhen the operator releases the treitdle, however, spring 197 returns it to normal position, and as rod 191 moves downwardly, the inclined face 193 thereon en gages block 194 and returns it to the position shown in dotted lines in Fig. 13, or in full lines in Fig. 12, thereby moving pawl tooth 88 into operative position, so that at the next two descents of lever 90 said pawl tooth will engage and turn the barrel sufli ciently for moving the thick portion 79 of arm 80 again into engagement with rod 66 to force said rod forward and cause the fastening inserting mechanism to become inoperative. During these movements rod 180, which carries roller 178, is depressed by the engagement of pin 188 with spring 185, causing the horn actuating mechanism to become inoperative.

As it is necessary for the stock to be rigidly supported while the wire is being forced into it, the mechanism for elevating the horn is actuated just prior to the operation of the fastening inserting mechanism, this being accomplished by providing the barrel with two teeth on each side, and by giving arm 80 two distinct movements in passing from one extreme position to the other, the first movement, when passing in the direction of the arrow shown in Fig. 13, carrying pin 188 out of contact with spring 185, so that rod 180 can move upwardly to carry roller 178 into operative position to actuate the horn, and the second movement carrying the thick portion 79 of the arm out of en gagement with rod 66, so that said rod can move rearwardly a suflicient distance to cause the fastening-inserting mechanism to become operative.

As the cutter-carrier head has to recipro cate twice to insert a fastening completely, it is necessary to suspend the feeding of the wire on the next'to the last cycle of operations of the machine and also not release the horn until after the head has descended for the second time to drive the partially inserted fastening, consequently arm 80 is given two distinct movements in passing from one position tothe other in the direction of the arrow Fig. 12, the first movement forcing the wedge-shaped part 83 into engagement with rod 66 thereby causing the rod to move slightly forward thus relieving the pressure of bar 58 upon friction plunger 54 which stops the further insertion of fastenings but does not hinder the driving of the. partially inserted fastening, and the second movement produced by the last cycle of operations of the machine causing pin 188 to engage the spring for carrying roller 17 8 into an inoperative position, forcing rod 66 completely forward and releasing the horn so that the stock containing the inserted fastening may be withdrawn.

For insuring two complete cycles of operations of the machine, so that a fastening may be completely driven after treadle190 has been once depressed, even though the operator releases it at the end of the first cycle of operations, rod 191 is provided with a shoulder 200 which engages a sustaining arm 201 whenever said rod is elevated, whereby said rod is held in its elevated position until the sustaining arm is withdrawn from engagement with said shoulder. Sustaining arm 201 is fastened to barrel 82, and guided by a fork 203 on the machine frame, and when said barrel occupies the position for holding the thick portion 7 9 of arm 80 in engagement with rod 66 (as in Fig. 14)

the sustaining arm will project into the path of movement of rod 191 as shown in Figs. 12 and 13. When said barrel is rocked in the direction for imparting the second movement to arm 80 for carrying it in the direction of the arrow Fig. 13, sustaining arm 201 will be withdrawn from engagement with shoulder 200, as shown in dotted lines in Fig. 13, and rod 191 will then move downwardly returningblock 194 to its full-line position in Fig 12 and moving pawl tooth 88 into position for engaging tooth 86 on the barrel so as to move said arm in the direction of the arrow Fig. 12 at the next descent of lever 90. The barrel is prevented from accidental rotative movement by means of a friction device 205 fastened to stud 84 and engaging said barrel.

In order that the stock may be held against foot plate 5 while the stock is being fed, there is provided means for causing the horn to exert a yielding upward pressure on the stock between the operations of the horn actuating mechanism for intcrmittingly elevating the horn. Said means preferably comprises a fiat spring 210 fastened to a rock lever 214 that is pivoted at 215 to the base or standard of the machine. One end of said spring engages a bolt 212 carried by lever 172. A roller 218 is fastened to starting treadle 190, and whenever sai treadle is actuated for causing the wire fee ing mechanism and the horn actuating mechanism to become operative, said roller will engage an inclined face 216 on lever 214 and rock said lever for causing spring 210 to exert an upward pressure on the horn, the rock lever being held in this positionduring the time the operator keeps the-treadle depressed.

It should be understood that after the starting treadle is depressed the machine passes through two cycles of operations,that

various parts are brought into proper relation so that the insertion of a fastening may be begun. After these first two revolutions {a single fastening completely, that is, insert ;it flush with the stock surface, it is necesgsary that the machine pass through four cycles of operations; the first, placing the parts for actuating the stock supporting means in operative position; the second, placing the parts for actuating the fastening inserting mechanism in operative position and clamping the stock rigidly; the third, inserting a fastening partially into the stock, severing the fastening a distance from the stock surface, feeding the stock laterally the required distance and causing the fastening inserting mechanism to again become inoperative; and the fourth, forcing the partially inserted fastening into the stock flush with its surface and releasing the stock supporting mechanism so that the stock with its completely inserted fastening may be withdrawn from the machine.

The operation of the machine, describing the position of the parts in detail, is as follows: After the driving belt has been slipped onto the fast pulley 8 the main shaft rotates continuously and the cuttercarrier head reciprocates in frame 14 which is automatically moved laterally at each cycle of operations by the lever 30. The thick portion 7 9 of arm 80 being in engagement with the rear end of rod 66 holds said rod in its forward position, so that presser bar 58 cannot actuate friction plunger 54 for causing the cutters to insert and sever the fastening material, and as pin 188 on said arm is in engagement with spring 185, roller 178 is held out of contact with the faces 95 and 176 of levers 90 and 175, so that no movement will be imparted to the latter lever for actuating the horn 170. The stock into which the fastenings are to be inserted,

.shown in Fig. 2 as a heel attached to a shoe,

is placed on the horn and the operator then depresses treadle 190, the upward movement of rod 191 fastened thereto turning block 194 and thereby moving pawl tooth 89 into operative position. As lever 90 moves downwardly during the next cycle of operations, which is the first in the operation of driving a fastening, pawl tooth 89 engages tooth 87 on barrel 82 to which arm 80 is fastened swinging said arm a partial movement in the direction of the arrow in Fig. 13, this movement carrying pin 188 out of engagement with spring 185 and permitting said spring to elevate rod 180 thereby carrying roller 178 into operative position between the engaging faces on levers 90 and 175. During the next, or second, cycle of operations, lever 90 will move lever 175 downwardly for elevating the horn to clamp the At the next, or third cycle of operations, the

friction plunger, being now in operative position, will cause the cutters to engage the fastening material as sliding head 16 moves downwardly, pass it through the opening in feed plate 106 and force it into the stock, and finally, when'at the end of the stroke, sever it to form a fastening. At this time lever 90 has been moved by cam-groove 94 into its highest position and as levers 90 and 175' are" still in engagement the horn is slightly depressed, thus unclamping the stock from the foot plate. As frame 14 immediately thereafter is moved laterally, the feed plate, being in engagement with said fastening, will through this means feed the stock. Duringthe next, and each succeeding cycle of operations, so long as treadle 190 remains depressed, another fastening will be partially inserted into the stock and a solid port-ion of feed plate 106 willengage the fastening whichwas partially inserted during the last previous cycle of operations and force it into the stock flush with its sur face, the horn being slightly elevated and depressed intermittingly, through the movement of lever 90, at the proper moments during the reciprocation of the cutters to enable the stock feeding mechanismto properly perform its function. Pattern cam 143 rotates continuously while the main shaft is in operation, therefore if the governing de vice is set so that both dogs on actuator bar 145} are in engagement with; the reciprocating rack-tooth bar 144 the throat block or fastening presenter 104 will be moved forwardly and backwardly either alternately or otherwise to carry one kind of fastening and then another kind of fastening into position to be acted upon by the cutters for forming a design corresponding to the layout of the particular cam used. Should either one of the dogs be released from engagement with bar 144 the result will beas previously set forth. When the treadle is released spring 197 returns it to normal position, and as rod 191 moves downwardly block 194 is thereby turned and pawl tooth 88 is moved into operative position. With the parts in this position 011 the next, which is the next to the last, cycle of operations, after a fastening has been partially inserted as usual, pawl tooth 88.will engage tooth 86 on barrel 82 and force the edge-shaped part 83 of arm 80 into engagement with rod 66, thereby operations, and forces it into the stock flush with the surface thereof. Thereafter as lever 90 moves downwardly and'the cuttercarrier rises, pawl--tooth 88 engages tooth 86' on barrel 82, giving arm a further movement thereby forcing rod .66 completely forward. 'This causes pin 188 to engage spring 185 and move roller 178 out of contact with levers 90 and 175, rendering the horn actuating mechanism inoperative and enabling the stock to be withdrawn from the machine.

While the preferred form of the invention is herein shown as embodied in a machine having means for inserting fastenings from but three strands of material, and means for severing, at the most, but two of these strands, it is obvious that more than two strands can be inserted and severed simultaneously if desired and the capacity of the machine for inserting different kinds of strands can be readily increased. a

'It will be understood that the invention is not limited to a machine in which fastenings are to be formed from continuous material and driven into stock, but in its broadest aspect covers a machine for inserting previously-formed fastenings, such, for example, as cut nails, as the automatic mechanism for presenting the fastening in position to be driven could be readily utilized to this end.
