HEELING-MACIHINE.

SPECIFICATION forming part of Letters Patent No. 374,894, dated December 13, 1857.

Application filed June 23, 1886. Serial No. 205,991. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES W. GLIDDEN,

of Lynn, county of Essex, and State of Massachusetts, have invented an Improvement in HeelingMachincs, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts. This invention in heeling-macliines has for its object to simplify and improve the mechanism for automatically transferri'ngthe top lifts into position between the top lift plate and the end of the heel of the shoe upon which the top lift is to be nailed or spanked.

In the machine herein to be described the top lifts are taken automatically from the hop per by means of jaws mounted upon a horizontally-reciprocating slide-bar, the said jaws having on operating with them a carriage, whereby the jaws are opened and closed automatically at the proper times to receive between them a top-lift, the slide-barbeing then moved forward to place the top lift in position to be attached to the heel. The slidebar and jaws have cooperating with them an auxiliary 7 inafter described, whereby the said spindle is adapted to yield slightly in a vertical position to compensate for ordinary variations in the thickness of heels and top lifts. I have provided the post of the nail-box within the diebed spindle with a notch, with which I have combined a latch or holder to prevent the nailbOX from rising, as will be described. I have also provided the die-bed spindle with a dashpot to act as a cushion. I have also provided novel mechanism, which will be hereinafter described, for automatically raising and lowering the die-bed spindle at predetermined intervals.

10 is a section of Fig. 8 in the line The particular features in which my invention consists will be hereinafter described, and fully specified in the claims at the end of this specification.

Fig. 13 is a vertical section showing the upper end of the spindleworking screw and means for connecting it with the walking-beam. Fig. 13 is a side elevation of the slide-bar of r the top-lift carrier and some of its attached parts, the jaws or levers being omitted; Fig. 13', a side elevation and plan of the carriage removed from the slide-bar. Figs. -14 and 15 are views in elevation and section of the mechanism for applying paste or' glue to the top lift as it is being applied. Fig. 16 shows a section and under Fig. 7 is a section of ICO side view of the top-lift plate and its swingpin and spring. Fig. 17 is a detail showing the cam which operates the top-lift carrier. Fig. 18 is a detail in top view of the top-lift hopper; and Fig. 19 is a side elevation ofFig. 18, one arm of the platef being broken off.

The frame-work A, of proper shape to sus' tain the working parts, is provided with a walking-beam, A, to move vertically a lastholding slide, A The walking-beam is operated by atoggle-joint composed of links A A, the link A" being connected with a rockshaft, A having on it a cam, A, which receives a roll at the upper end of a link, A

jointed toalever, A pivoted at A, movement of the lever and link causing the roll of the link A within the cam A to move the togglejoint in one and then in the other direction. The die-bed spindle 13, held in guides 13, has at its upper end the usual trimming-levenB and above it, supported in well-known manner, is the usual nail-box, B, provided with a top-lift plate,

Power is applied to the machine by means of a belt on a pulley, B, fast on the driving shaft B. At one side of the fast pulley is a loose pulley, The shaft B has fast upon it two pinions, D and B The pinion B engages a toothed gear, B located at the righthand side of the machine, butloose on ashaft, B, having attached to it at one end a dog-carrier, 0, provided with a dog, 2, controlled by a dog-shoe, O, on a slidebar, C

The dog 2 is at times made to engage the internal teeth of the continuously-driven loose wheel B and durin such en a ement the 7 Z: O b

shaft B is rotated to move the lever 0", (see Fig. 3,) which reciproeates the carriage O on the way 3, attached to the frame-work, the said carriage having attached to it a chain, 0, extended over the sprocket-wheel G, which, through a cross-head, C and pins 0 actuates thetrimming-lev'er B the said chain also passing over a loose sheave, O", mounted on a stud at the back part of the frame-work. The diebcd spindle has connected with it a link, D, forming part of a toggle-joint, the other link, D, thereof having a fixed fulcrum, D

The center pin, D of the toggle-joint has connected with it a pressenrod, D, having a shoulder, (shown by dotted lines, Fig.1,)which at proper times is struck by a crank,D (shown by dotted linesin Fig. 1 and full lines, Fig. 4,) forming part of the crank-shaft D, the said crank and rod starting in usual manner the toggle to lift the die-bed spindle B at the proper times, as when the heel is being nailed upon the shoe and when the topliftis being spanked upon the projecting ends of the nails partially driven into the heel, the shoe being at such times upon a last applied to the last-holding slide A in usual manner.

The parts so far described are in common use in the so-ealled McKay and Bigelow heel nailing and trimming machine, so that their operation need not be herein more fully set forth. The machine alluded to has been selected as one upon which to apply my improvements, now to be described, the same consisting, essentially, in mechanism whereby the top lifts may be automatically taken from a pile and be fed into position to be spanked upon the top-lift end of the heel.

My invention has also for its object to increase the speed of the working parts.

The pinion D (see Fig. 3,) fast, as stated, on the driving-shaft B, engages a toothed gear, D, fast on and drives the shaft D continuously. The shaft D has fast upon it a pinion, D", which engages and rotates contin- 4. The shaft 4 at one end has attached to it an arm, 7, provided with a dog, 6, controlled by a stop shoe, E, attached to a sliding rod, E. The dog 6, when released from the stopshoe, engages the internal teeth, 5, of the colr tinuously-rotating gear D, which latter, through the dog, causes the shaft 4. to be rotated in unison with it. The slide-rod E, carrying the stop-shoe E, is reciprocated at the proper time by a forked lever, E, pivoted upon a bolt, 77, (see Fig. 1,) the upper end 01' the said lever having a roll or wheel, 108, which is acted upon by a cam-hub, 8, loose on a pin, 9, held fast in a bracket, 10, the said cam having an arm, 12, which is provided with a pin, 18, that by link 14 is connected with the center pin, D", of the toggle D D,before described, the said toggle as it is straightencd by the movement of the pressure-rod D acting to turn the cam 8, and also the lever E and move the rod E and the stop-shoe E to release the dog 6, so that it, acted upon in usual manner by a suitable spring, may be engaged by the wheel D and start the rotation of the shaft 4. The under side of the presser-rod D is connected with one end of the foot-lever F, pivoted'at F by a link. (Shown by dotted lines in Fig. 1.

\Vhen the operator desires to start the ma chine, it is only necessary to place his foot on the said lever, which effects the elevation of the presser-rod D in position to have its shoulder 109 ,(see Fig. 4.) struck by the crank D to straighten the togglelevers D D.

The shaft 4,before described, is surrounded by a sleeve, h, provided with an annular groove, h, which is entered by usual projections carried by the forked end of the pivoted hand-lever h This sleeve is connected by a spline, h", (see Fig. 6,) with the shaft 4:, and is also provided with an inclined or spiral slot, h, which receives in it a block, h, held loosely by a pin or screw, h screwed into the hub h, the latter having attached toits flange by the screw h the cam k The sleeve it re ceives upon it the hub of the side-grooved cam b, which moves the toplift-carrying slide, to be described, and the said cam has attached to it by a screw, '5, the hub i", which is pro vided with two cams, 1 i. The hub of the cam b and the hub z" are cut out to leave a chamber, 112, into which may enter a spline or key, 2', fast to the sleeve 72, when the said uously a toothed gear, D,'loose on the shaft" sleeve is moved into its farthest position to the leit in the direction of the arrow in Fig. 5, the spline 1"", when in the said socket, permitting the cam b and hub 11 to remain at rest while the shaft 4 and sleeve it continue to rotate. WVhen the sleeve h occupies the position shown in Fig. 5, the spline i enters a groove, 113, within the hub of the cam I), thus causing the rotation together of the shaft 4, the sleeve, and the said cam. Y

The flange ot' the hub 7L8 has a side cam, 79, (see Fig. 4,) which at the proper time operates upon the roll at of the lever m, pivoted at 771 causing theslotted upper end of the said lever (shown in dotted lines, Fig. 3, as embracing a pin, 80, of the slide-bar G to move the said slide-bar to the right and place the dog-shoe G in position to release the dog 2 and permit it to engage the rotating gear B and start the shaft 13, to set in rotation the usual trimming mechanism, the die-bed spindle being elevated.

The die-bed spindle (see Fig. 3) has attached to it a cylinder, 114, open only at its lower end, it forming what is called a dash-pot, the said cylinder fitting over the end of a piston, 115, attached to the frame-work, the said cylinder and piston, by the compression of the air therein, serving as a cushion in the descent of the die-bed spindle, thus doing away with the usual rubber packing or cushion usually employed in the McKay and Bigelow machine.

The screw in, connected loosely, as shown in Fig. 13, with the upper end of the spindle 84, to which is joined loosely the usual lastholding slide, A, is screwed into a threaded bushing, 85, provided with a head, m the said bushing being passed through a spring, m", placed in a chamber in a sleeve, m", pivoted, as usual, between the forked ends of the walking-beam A, the said bushing receiving upon its upper end a nut, m. Normally, the spring m keeps the bushing 85 in the position shown in Fig. 13, the nut m resting against the upper end of the sleeve m, so that when pressure is applied to the heel to unite the same to the shoe the bushing is permitted to rise, somewhat compressing the spring in, the spring accommodating itself to slight variations in the height of heels and keeping the outer end of the heel firmly against the nailblock 13 during the operation of driving the nails, thereby obviating liability of bending the nails should the heels being made he of less than the minimum height for which the machine has been set. The cam 11 vibrates the lever b, pivoted at b and having a rollerstud entering the groove 116 of the said cam. (See Fig. 17.) The slotted upper end of the lever b engages a pin, 1), of the slide-bar b". The slide-bar bf has attached to it near its outer end by screw 86 a crosspiece, 0 (see Figs. 8, 9, and 10,) the said cross-piece being slottedto receive the fulcrum-studs c ,onwhich are mounted the levers or jaws 0 of the toplift holder or carrier, the said fulcrum-studs being made adjustable in the said slots by the screws 0, and being clamped in adjusted position by the nuts 0, the adjustment of the fulcrumstud providing for top lifts of different sizes.

The crosspiece c is bored at its center parallel to the bar b, to receive loosely the front end of a slide-rod, d fastened by a pin, 117, (see Fig. 9,) to a cam-carriage, (Z, grooved at its upper side, as shown separatelyin Fig. 13*, to fit the lower side of the slide-bar b, which in cross-section is shown as of T shape. The rod d between the front side of the cam-carriage and the cross-piece c, fixed to the bar I)", is surrounded by a spiral spring, cl", which acts normally to push the carriage backward away from the said cross-head. The rcarend of the rod d enters loosely a hole in and is guided by the bearing-block d, attached by suitable screws to the slide-bar b".

The cam-carriaged at its upper side is provided with two diagonally-placed but oppositely-inclined slots, d, (see Figs. Sand 13",) into which enter the roller or otherstuds, 118, (see dotted lines, Fig. 8,) at or near the rear ends of the jaws or levers c. The bearingblock at receives the screw 202, which serves as the fulcrum for the latch 203, (see Fig. 13%) having a notch, 204, at its outer or free end, a spring, 205, normally keeping the said latch lifted. As the slide-bar b and crosspicce c are moved back from the nail-box after the jaws have given up a top lift, the spring (1 acts to force the carriage (1 into its farthest position away from the cross-piece c keeping the jaws closed; but before thejaws arrive in position to be supplied with a top lift, the carriage strikes at its rear side against the end of a finger, 6, having a cam-surface, (seeFig. 12,) and having a shank, c, entered'into a. guide, e,where it is acted upon by a spring, 0, which normally keeps the finger elevated in position to strike and stop the carriage d.

Stopping thecarriage while the slidebar continues to move causes the roller-studs at the inner ends of the jaws or levers c to travel in the cam-grooves ot' the carriage in such direction as to open the jaws just before their acting faces reach thetop lift next to be taken; but as soon asthe acting faces of the said jaws reach a position opposite the top lift next to be taken, a lug, d, at the left side of the slidebar in the backward movement of the latter acts upon the upper cam-shaped or inclined side of the finger e, and pushes the same down against the action of the spring 6 until the end of the finger is released from the said carriage; but just before the said finger is removed from contact with the said carriagethe spring 205, connected, as described, with the latch 203, pivoted at 202, causes the said latch to be elevated, so that its notch 20; engages the latch 203 in the farthest backward movement of the slide-bar b is struck by the stationary stop 206 and is depressed, permitting the spring d to act upon and move the carriage d away from the cross-piece to close the jaws quickly upon the top lift. In this posi tion of the parts the slide-bar b is again moved forward, and the jaws place the top lift held by them between the heel of the shoe and the top-lift plate 9", which has been thrown into position by its spring 9 to cover the nail-box B The hopper to contain the top lifls Z to be fed to the jaws c is herein shown as composed of two trough-like pieces, f f, having ears f which at each side of the hopper are united by rods f, the lower ends of which enter holes in an adjusting-plataf, (see Fig. 1,) guided in suitable slots or ways of the framework, the said plate being made adjustable by the adj usting-screwf in a threaded lng,f, the inner end of the said screw being grooved annularly to engage loosely the upturned end of the said plate. By turning the screw f in one or the other direction the said plate and the hopper may be adjusted to place the hopper in proper position with relation to the open jaws of the top-lift carrier.

The hopper has at each sidea slot, as shown at one side in Fig. 1. The hopper receives within it a weighted follower, f made as a metal plate, having pins 12L projecting from opposite edges, to enter the slots between the two halves of the hopper. (See Figs. 1 and 18.) This.follower acts to force or feed the top lift down in the hopper as one top lift after another is taken from the lower end of the hopper by the top-lift carrier. When the top lifts are being supplied to the hopper, the latter being then temporarily removed from the machine and inverted, the follower acts as a cap for the hopper to enable it to be filled from its lower end, then uppermost. The pins orprojections of the follower cannot leave the slots of the hopper because of the shoulders 126. The hopper has at one side a hole to receive a pin, 127, which isinserted after the hopper has been filled, the said pin preventing the escape of the top lifts from this end of the hopper as the hopper is being placed in the machine. The pin 127 is removed after placing the hopper in place in the machine. The slide'bar b is guided in its movements by horizontal ways out in the block 0, attached to the frame-work by bolts 90. The slide-bar (see Figs. 8, 9, and 13) is grooved at its sides for some distance to form guides for the auxiliary slide t, the legs 128 of which are placed in the said grooves, the said slide serving as a movable end for the slide-bar b", in order that the effective length of the said bar may be varied, as will be de scribed. As the slide-bar I) is moved toward the rear of the machine,the ends of the legs 128 of the auxiliary slidebar t strike the end of the guide c,and the auxiliary slide is stopped,whilc the bar If continues to move backward, such movement of the bar b backward leaving the auxiliary slide-bar t in position below the hopper to sustain the lowermost top lift after the end of the slide 1) passes to the rear edge of the said top lift, taking with it thejaws or levers 0 (See Fig. 8.) Sufficient friction is exerted be tween the legs of the auxiliary slide-bar and the slide-bar b to prevent the movement of the said auxiliary slide-bar tthereon,except when acted upon by a force sufficient to overcome the said friction. As the slide-bar b moves forward with a top lift, the outer downturned end of the bar it meets and is stopped by the rear side of the nail-box B while the slide b continues to move forward, causing the jaws to carry the top lift into position between the heel and top-lift plate. The lower end of the hopper being open and the pin 127 removed, permits the lowermost one of the pile of top lifts in the hopper to rest at times upon the upper side of the slide-bar b and at other times upon the auxiliary slide t. The auxiliary slidet is pushed into the slide-bar I) until the end of the slot thereon (see Fig. 8) meets, or nearly so, the end of the slide-bar b. To prevent the edge of the, heel showing a check or open space between the top lift and theheel proper,l have provided the framework with a bracket, 1*, having a paste box or receptacle, 1", and having at its lower end a roll, or it may be a brush, 1' or other equivalent device, by which to apply paste, glue, or

cement to the upper side of the top lift as the latter is carried forward by the top-lift carrier, the roller being located between the hopper and the nail-box. The top-lift plate 9'' has extended through it a swing-pin, 9, provided with a slot, 9 to receive the inner end of a clock or other spring, 9 the other or outer end of the said spring being made to engage a slot, 9, in the top-lift plate. The pin 9 upon which the top-lift plate swings, enters the nail-box and is fixed therein in adjusted position by a set-screw, 9 the spring normally acting to keep the plate 9 in position over and to cover the holes in the nail-box.

The frame of the machine has pivoted to it at n a latch, n, to engage a pin, a", of the toggle A? and A in each of its extreme positions, to thus prevent accidental movement of the said toggle. When the die-bed spindle is raised, the latch-lifting rod a, connected --to the lever A is lowered to place the projection a at the side of the said lifting-rod below the lower side of the latch, so that as the die-bed spindle is lowered the said shoulder a in rising will strike the lower side of the latch 'n and lift it from engagement with the pin a of the toggle, leaving the latter free to be turned. The latch a is normally held down the dog.

line with one of its notches. The shoe to which the heel is to be attached is placed upon a last, and the last is applied as usual to the slide A The slide A is pushed back, to place the shoe in correct position over the nail-box, and the heel, with nails partially driven therein, is applied to the nail-block, the top-lift plate being turned aside, the undriven portion of the nails entering the holes at the upper end of the nailbox,leaving them in position to be acted upon by the ends of the usual drivers as the die'bed spindle has imparted to it its first rise, the usual drivers at that time acting to drive the nails through the heel and into the sole of the shoe, the ends of the nails being, however, left protruding from the small end of the heel to receive the top lift.

The operator to start and effect the rising of the die-bed spindle will place his foot upon the lever F,depressing its outer end far enough to lift the presser-rod D high enough for its shoulder 109 to be struck by the crank D which latter moves the presser-rod in the direction to straighten the toggle-joint D D and lift the die-bed spindle. The nails having been driven, as stated, the cam strikes the roll a at end of the elbow-lever a, (shown separately in Figs. 7 and 7 causing the cam-shaped arm a thereof to be turned sufficiently far to strike the shoulder 14 of the presser-rod D" and move it backward to break the joint D D, and permit the die-bed spindle to descend; and during this time the cam b in its rotation moves the lever b to carry forward the slide b and place a top lift in position above the top-1ift plate, which has been turned to cover the nailholes in the nail-box and rest between it and the end of the heel, and thereafter the cam i, acting upon the lower side of the presser-rod D, lifts the latter, so that its shoulder 109 is again brought in the range of the crank D to again straighten the togglejoint and raise the die-bed spindle a second time, it remaining up while the heel is trimmed, in usual manner, and the heel having'been trimmed, the cam i, projecting from the hub t but at a different angle, acts upon the roll a, it turning the lever a to again break the toggle, as did the cam 1", before described, the breaking of thetoggle again effecting the lowering of the die-bed spindle and the backward movement of the presser-rod. As the toggle joint D D is straightened, it, through the pin D and link 14, connected with the pin 13 of the arm 12, causes the partial rotation of the cam-hub 8 on its fulcrum 9, so that the said cam turns the lever E and moves the rod E and stop shoe E to effect the release of the dog 6, the latter engaging the internal teeth of the wheel D causing the shaft 4 to be positively rotated by The dog 6 is retained in operative engagement with the inner teeth of the wheel D while the shaft 4 makes substantially two rotations, or until the top lift has been attached to the heel and the heel trimmed, at which time the cam 2' operates, as before described, to break the joint in the toggle D D.

In the revolution of the shaft 4 the cam projection 79 on the hub h through the lever m and the rod 0, before described, moves the dogshoe 0 to effect the engagement of the dog 2 with the inner teeth of the wheel B and rotate the shaft B one full rotation to thus actuate the trimming mechanism and trim the heel, after which the dog 2 is thrown out of engagement with the teeth of the wheel B by the spring 92 on the rod 0 it operating in opposition to the lever m.

In case it should be desired, upon the machine described, to attach heels and omit the usual blind top lift, this may be done by moving the lever If in the direction to draw the sleeve h in the direction of the arrow, Fig. 5, until the spline i enters the chamber 112, such movement leaving the cam b and the hub t" and its cams i t loose or stationary, but the shaft 4 continues to rotate; but to enable the cam h under such conditions to operate to lift the presser-rod D? at the proper times in order to effect the lifting of the diebed spindle, it is necessary to somewhat change the position of the cam h on or aboutthe shaft 4 and sleeve h, which is done, as before described, by the inclined slot If.

The lever A has jointed to it the rod w, extended down through an ear, w, and a spring, w where the rod has attached to it a nut, w. This rod 20 is common to United States Patent No. 332,032.

The nail-box B has rigidly attached to its lower end, as usual, a post, 208, which enters a hole in the top of the die-bed spindle B, the said post at its lower end resting upon a plunger, 209, supported by a spring, 210, the said spring being depressed as the die-bed spindle is raised, the heel resting upon the top of the said nail-box, preventing the nail-box from rising while the nails are being driven therefrom into the heel. The post is as common to the McKay and Bigelow heeling-machine.

When applying a top-lift automatically, as herein provided for, the movement of the parts being in rapid succession, it sometimes happens that the nail-block, which-must descend by gravity, does not descend as rapidly as the die-bed spindle, and consequently the nail-box is in the way of the top-lift carrier. To obviate this difficulty I have provided the post with a suitable notch or slot, 212, (see Fig. 3%) and to co-operate therewith I have provided the die-bed spindle with a latch, 213, herein shown as pivoted near its center and acted upon at its lower end by a spring, 214, which normally keeps'the latch in the said notch or slot, so that as the die-bed spindle is lowered positively the post and nail-block will be moved down positively in unison with it, or at the same speed, and cannot hang back, nor can it rebound.

In a machine to apply top lifts automatically at high speed I have found it essential that the breast of the top lift be arrested or stopped at a definite position wit-h relation to the top lift, nail-box, and heel. So to accom- IIO . with the top-lift clamping jaws or levers and plish this I have herein employed the shoulder 216 on the top-lift plate.
