Mass, assignor to United Shoe Machinery Corporation, Flemington, N. J., a corporation of New Jersey Application October 4, 1940, SerialNo. 359,751 34 Claims. (Cl. 1-32) This invention relates to machines for inserting fastenings to secure together work-pieces, it being more particularly concerned with the attaching of heels to shoes,asby nails driven from within the shoes into; the heels.

In machines of this. character, the inserting force, which must be exerted upon the entire group of fasteners employed to effect attachment, may be so great as to require an excessive holddown-pressure to retain the workagainstdisplacement upon its support. To avoid this, it has been. proposed to divide the entire group necessary for each attachment into sets which are inserted successively. My invention has as an object the provision for this purpose of fastening-inserting 'means, which is both eflicient and extremely simple. In the attainment of this object, I'arrange to reciprocate, both within a frame and withina jack or work-support mounted on said frame, sets each made up of a plurality of flat plates situated side by side, the plates of each pair ofthe two sets being of similar form, vertically alined and'registering with each other. The respective pairs ofplates are connected for positive movement together in oppoa slide is movable in the frame of the machine them. The gearing may be actuated through site directions. The support-plates carry fasteningrdrivers, and the frame-plates are reciprocated, as by a pluralityfof cranks upon a driving shaft. Such an organization is-compact, inexpensive to manufacture and so durable as to require little maintenance-expense. To permit the inserting design to be altered readily, the work-support is slidably, mounted in ways upon the frame, and there isconnecting means between the frame-plates and support-plates, which will separate when the support with its plates and drivers is to be changed.

It is a commonpractice, in connection with the supply of fastenings to insertingmechanisms of such'm-achines as those for attaching heels, to deliver thefastenings to loading mechanism at one positionand to transfer. the load to the inserting. mechanism atan operating-position. Another object of this invention is to reduce the number of transiers-otthe fastenings, by'eliminating the loading. mechanism and making the delivery directlyto the inserting mechanism. To this end, the shoe-support or,jack, with its fastening-drivers, is movable under the power of the machinebetween the leading position, at which iasteningsmay be supplied to its drivers either by hand or automatically through tubes from a distributor, and the operating position, where there is means for actuatingthe drivers to insert the fastenings in the work. Morespecifically,

clutch mechanism controlled by the operator. When the drivers are arranged in the work-support in groups operated through sets of separable plates, mounted respectively in the frame and work-support as previously pointed out, the slide, in moving the support from'the loading position into the operating position, causes connection between the sets of plates.

In heel-attaching or other fastening-inserting machines, the work must be held firmly upon its support to resist the driving forces, and it is customary to apply to said work preliminary or measuring pressure, which establishes contact of the engaging elements with the work by their relative movement and permits a positioning of said work, thereafter final pressure being applied to clamp the work for the insertion of the fastenings. A further object of this invention is to cause, in a novel and effective mannerand without delay, the application of full work-retaining force .with no possibility of its diminution through slipping between force-transmitting elements. This result, I obtain by combining with relatively movable work-pressure members, as fastening-inserting mechanism and heel-abutment mechanism, a member for causing the application of final pressure and an actuating.

member movable to operate the pressure member and upon which said pressure member is movable, together with means for securing the pressure member against movement upon the actuating member to lock preliminary pressure upon the work. The pressure member may be rotatable during the application of preliminary pressure, and then positively secured against rotation to effect. the locking Thereafter, its bodily movement may produce-final pressure, which may be increased during insertion of the fastenings and may be limited in magnitude. The preliminary pressure is preferably created by the operator, while the final pressure is under the power of the machine and governed-by the operator. To give this control, the actuating member is powerdriven, and there is a latch by which said actuating member is held in inactiverelation, to be released by means through which the operator governsthe power means. The release of the actuating member gives the locking effect for the preliminary pressure previously refer'red'to, and

unfailingly holds this upon the work, it being applied without the loss of time which would be introduced were the lock to be produced during the power-cycle of the machine. I have shown the final pressure as created by gearing, preferably of spiral form having an element arranged for compound movement, which may be made up of bodily and rotary components. Idle movement of this element in one direction, as its rotation, will permit the application of the preliminary pressure by the operator, while the second or bodily movement may produce the final pressure under the power of the machine. The driven element of the gearing is upon a spindle having a screw threaded into a nut upon the heel-abutment and movable against the resistance of a spring. The element having the compound movement is under the influence of the actuating member. It is free to rotate upon said actuating member, while the other gearing element is being turned during the travel of the heel-abutment for the application of preliminary pressure, and

is thereafter clutched to said actuating member,

as a consequence of the movement thereof. The actuating member is preferably latched to maintain the clutch out of engagement during the creation of preliminary pressure, this latch being released when the operator causes the rotation of the power means, as a cam which applies final pressure. 7

In the accompanying drawings, in which is illustrated one form of the invention,

Fig. 1 shows my improvedfastening-inserting machine in broken side elevation;

Fig. 2 is an irregular vertical transverse section; 7 e

Fig.3, a broken front elevation of the worksupport and abutment mechanism; and

Fig. 4, an enlarged horizontal section on the line IV-IV of Fig. 3. r

The machine-frame is preferably in the form of a column I'll, at the front of which rises from a bracket l2 a post 14, which may be considered as a portion of the frame. At its top, the post is tied to the body of the frame by a horizontal brace 16, which extends back into the interior of the column. In the brace are horizontal ways [8, in which a base 28 of a jack or work-support 22 is mounted to slide This jack is movable, in a manner to be later described, between a forward operating position, as it appears in the drawings, and a rearward receiving position beneath a foot-plate 24. Through the foot-plate, with its connected tubes 26,. nails or other fastenings are supplied from an unillustrated distributor. In the jack are vertical passages 28 arranged in accordancewith a particular nailing design, and in these passages nail-drivers are movable. The forward or breast-drivers 3f], 30 and the next or intermediate drivers 32, 32 rise in pairs from vertically-extending plates 34 and 36, respectively, while the fifth .or rear driver 38 is carried by a plate 40. Each of the driverplates is separably latched in the jack by a springactuated pin 42, guided in the jack-body and entering a vertically elongated depression in the corresponding plate. When the jack is removed from its Ways for the substitution of another having its drivers arranged according to a different design, the latch-pins prevent the accidental separation of the plates and drivers from the jack, yet permit them to be removed for driver-adjustment or for the replacement of broken drivers. The separable retention of the jack is effected by a spring-actuated latch 44, movable in the lower portion of the jack and engaging its actuating slide 46. The jack- plates 34, 36 and 40 are guided for vertical movement side by side in a cavity in the jack, as may be best seen in Fig. 4 of the drawings. edge of each plate is a recess 50, shown as T- shaped (Fig. 3), this receiving a complementally formed projection 52 at the top of the corresponding one of three plates 54, '56 and 58 guided in the frame-post l4 in a manner similar to the respective plates 34, 36 and 48 and of like form. These lower driver-actuating plates have connections by which they are moved positively in opposite directions, as they also move the respective upper driver-carrying plates with which they are vertically alined. Springs for the retraction of the drivers are therefore unnecessary.

Each connection may consist of a circular projection 60 from the bottom of one of the actuating plates, this being surrounded by a complemental depression 62 in a connecting rod 64. Each connecting rod is operated by one of a set of three cranks 65, 68 and Ill, separated from one another by 120 about a driving shaft 12. This shaft is journaled horizontally in the lower portionof the column Ill, and receives power constantly, while the machine is in use, through gearing l4 and clutch mechanism indicated at 76 (Fig. 1). The initial heights of the drivers are such that, as the spaced cranks are turned through one revolution in the direction of the arrow in Fig. 3, the drivers 30 are first lifted through the pair of plates 54 and 34 to insert in the jacked Work the nails which they carry. After these nails have been fully driven, the drivers 32 act, followed by the drivers 38. As a result of this progressive insertion, the force necessary to resist the displacement of the work from the jack 22 is never more than that which will adequately oppose the driving of two nails. Obviously, the number and manner of grouping of the sets of plates and drivers may be altered, as is found convenient.

The jack-base 20 has extending rearwardly from it the slide 46, previously referred to, this being guided in the brace l6 and having upon its upper face rack-teeth 89. With these teeth meshes a gear 82 fast upon a sleeve 84, rotatable about a shaft 86 journaled horizontally in the column Hi. This shaft is driven from the constantly rotating shaft 12 through gearing 81, portions of which appear in Figs. 1 and 2. At the outer extremity of the sleeve a pinion 88 is secured, and has meshing with it a gear-segment 98 mounted to oscillate about a spindle 92 projecting horizontally from the column. The outer side of the segment has a projection 94 entering a cam-groove 93 in a disk 98 surrounding the shaft 88. The disk may be rotated from the shaft through clutch mechanism 0 contained within a casing I forming a part of a handlever I02, fulcrumed at I84 upon the framecolumn and arranged for manipulation by the operator. The hand-lever is held normally raised, with the clutch disconnected, by a tension-spring M15. The type of clutch employed is not important, one which is suitable being that disclosed in Letters Patent of the United States No. 2,214,835, Lancaster, September 1'7, 1940. Depression of the lever [62 and consequent engagement of the clutch will cause a single rotation of the disk 98. This, through the sleeve 84, gear 82 and rack 80, will produce a complete reciprocation of the jack-slide 46 to carry the jack 22 from its operating position, as seen in In the lower the jack by a tension-spring I 22 'Fig. 1, to a point-beneathrtheifoot-plate1t24to receiyeauload of nails-and ba'cktto operating position. 150 and; .140and'theframe-platesifid; 56 .andl58 by which they are actuated, are separated, the depressions .in thejack-plates remaining inhorizontal registrationzwith the: pro-jectionso-f the frame-plates In lits travel, the connecting means 52, between the l-ja ck-plates- 34, i136 .and

'For this purpose, the .diskhas a peripheral cam-surface I06 :with which contacts a roll I 08, rotatable upon onearm of a bell-crank-lever I I0,fulcrumed .upon' the spindle 92. .The roll is held against the I cam-surface by a tension-spring H2 and, as the disk rotates, connection of the lever IIO .to the distributor by arod H4 will cause the actuation of the picker-plate. or disks, in. one direction to tension a spring, and thereafter release the picker-device or devices to permit them,under the influence of the spring, to deliver av load of nails from the raceways. "The separation of the .nails .will occur during the rearward travel of the jack, they dropping through the tubes and foot-plate into the. passages 28, as said jack waits to receive them.

Situatedabove the jack "22 is a holddown or heel-abutmentmechanism A, which may be conventional inform. It is mounted upon a slide I20 guided for vertical movement at the front of the column I53, and held normally elevated from extending between .thebottom of the column and a lever I24, fulcrumed within the column and pivoted to the .slide. To bring the abutment A into preliminary engagement withaheel to be attached, the lower secured at I 46 inside the column. The spindle,

turns within a bushing MS threaded into the top of the casing, and fast upon its lower extremity is a spiral gear I 50 normally resting upon a stepbearing I 5| at the bottom of the casing. Between the gear and .a thrust-bearing I52 at the lower,

end of thebushing, a compression spring E54 interposed. By varying the vertical position of the bushing, the-resistance of the spring to compression may be altered. Guided forvertical reciprocation in one side of the casing is an a'ctuat-- .ing rod I 56, splined at I53 to prevent rotation. Secured to the rod is a collar I50, andresting .uponithis is a spiral pinion I62 meshing with the spiral gear: I50 and normally free for rotation thereby about the. rod.

The nut I38 isthereby caused shaft=12-under the power'of themachine,

to'descend, lowering the slide lzll'so' the abutment A applies final clampingpressure-to the wwolrk. The-magnitude ofthis pressure may be variablyjdetermined by :turning the-bushing M8 to change the resistance of the spring I54 to compression. When,in this pressure-movement, the

xspring'yieldsythe force applied to thework by the abutment A -is through said" spring, which, as it is .tained upon the rtimate: pressure is so. limited that the. heel will "110132199 crushed. As the cam-depression I32 a :"proaches the: roll; IM'atthe termination, of the compressed, offers'a gradually increasing resist- -.ance. "This correspondingly.increases the holddownpressure, so,-as thefastenings are driven :farther into the work, it is more effectively re jack. *Atithe same time, the ul operating cycle, the cam-groove I82 lifts the end I90 of the lever I86, so the actuating rod I56 is elevated until its lower extremity may be drawn by the spring I12 into the recess in the arm H0. The clutch-teeth I68 are now latched in their disengaged relation; the disk I80 stops with its cam-depression I92 opposite the lever-roll I84; and the screw I40 is freed forrotation by the nut I38 during the succeeding application of preliminary pressure to the work. The extent to which holddown-pressure is placed upon the work as the driving of the fastenings progresses may be determined, not only by the resistance of the spring I54, but also by the contour of the camgroove I82. By the latter, for example, the workretaining force may be increased just as the heads are being sunk in the insole.

In using the machine, there being a jack 22 with its driver-passages 28 arranged in the desired nailing design latched at 44 to its actuating slide 46, the operator depresses the lever I02 to cause the connection of the cam-disk 98 to the constantly driven shaft 86 by the clutch mecha nism C. The cam-groove 96 of the disk, acting through the gearing 88, 82, 80, carries the slide rapidly back until it approaches its nail-receiving position beneath the foot-plate 24, slows it as it approaches thetermination of 'its' travel, and holds it temporarily at rest with its passages 28 in registration with those of the footplate. At this time, the cam-surface I06 of the disk 98, acting through the rod II4, causes the delivery of a load of nails N from the distributor, these being deposited; points up, in the jackpassages upon the upper ends of the contained drivers, Then, the cam-groove 96 causes the return of the jack, first rapidly and then at a reduced rate, to its initial position beneath the abutment A, it being there maintained by the cam-groove, the rotation of the disk 98 having been stopped by the disengagement of the clutch C. In the rearward movement of the jack, the depressions 50 in its plates leave the projections 52 upon the frame-plates, but again come into co-operation with them upon return to the forward operating position. It is to be observed that this loading of the jack with nails is accomplished by direct delivery to it, without the complication and uncertainty produced by interposed loading mechanism.

The operator places a shoe S upon the jack 22, locates a heel I-I upon the heel-seat and depresses the treadle I28. This turns about its fulcrum I30, and through the rod I26 draws 'down the slide I20 until the abutment A engages the heel. Since the clutch-teeth I68 and I66 are now separated, the rod I56 carrying the former being latched up at II0, the spiral pinion I62 is free to turn idly, as is the meshing gear I50 and its spindle I42. The nut I38 upon the descending slide, therefore rotates the screw I40 without effect upon the slide. When contact of the abutment with the heel has been established and the work properly positioned upon the jack, the continued downward movement of the treadle transfers its fulcrum to the pivot I32 upon the rod I26. Through the link I34, the spindle I35 is turned to at once free the rod I56 from the latch-arm H0. The spring I12 draws down the clutch-teeth I68 into engagement with the teeth I 66, securing the pinion I62 against rotation upon the rod. The spindle I42, with its screw I40 and gear I50, being thus held against rotation, the abutment A is positively locked in its preliminary pressure-supplying relation, before the power operation of the machine starts and without the possibility of accidental retraction. Immediately following this, the further rotation of the spindle I35 with the stop-arm I36 frees the clutch mechanism I6 for engagement; the shaft I2 is rotated; and the power-cycle of the machine is initiated. The cam-groove I82 in the disk I causes the lever I86 to draw down the rod I56; and the now locked pinion I62 acts upon the gear I50 and through the inclination of the intermeshing teeth rotates the spindle I42 with its screw I40 to apply clamping pressure in a manner and to an extent determined by the resistance of the spring I54. With the work thus firmly held against upward displacement, the rotation of the cranks 66, 68 and I0 produces the successive reciprocation of the frame- plates 54, 56 and 58 and the connected jack- plates 34, 36, 40 positively in both directions. The sets of drivers 30, 32 and 39, therefore rise to insert the sets of nails N which they carry through the insole of the shoe S into the heel H, and are restored to their initial positions when disengagement of the clutch mechanism I6 stops the rotation of the shaft I2. Because preliminary pressure is looked upon the work by the clutchteeth I66, I68 before the power-cycle of the machine begins, there need be no clearance between the insole of the shoe and the points of the nails upon the first-actuated drivers, giving a substantial saving of time. As the rotation of the disk I80 terminates, the cam-groove I82 elevates the rod I56 sufficiently for the spring I12 and arm I'I0 to latch up the said rod. The clutch-teeth I 68 are separated from the teeth I66, so the gearing I 62, I50 and the spindle I48 with its screw are free to rotate. The slide I20 is therefore released and is raised by its spring I22 to separate the abutment A from the jack. All the elements of the machine are now in their normal positions, and, upon removal of the heeled shoe from the jack, it is ready for the succeeding operation, If the nailing design is to be changed, the operator, releasing the latch 44, pulls out the jack from its ways I8, the contained plates and drivers being retained within said jack by the latches 42. When the jack to be substituted is inserted in the ways, the latches for its plates locate the plate-depressions 50 in their correct relation to receive the projections 52 of the frame-plates. The latch 44 secures the jack to the slide 46, with this connecting means 50, 52 engaged in proper vertical registration.
