HEEL-MAKING MA CHlNE- SPECIFICATION forming part of Letters Patent No. 443,908, dated December 30, 1890.

Application filed August 11, 1890. Serial No. 361,657. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM J. FAHNLEY, a citizen of the United States, and a resident of Lynn, in the county of Essex andState of Massachusetts, have invented new and useful Improvements in Heel-Making Machines, of which the following, taken in connection with the accompanying drawings,isa specification.

This invention relates to improvements in' heel-making machines, and it is carried out as follows, reference being had to accompanyin g drawings, wherein Figure 1 represents afront elevation of the machine, and Fig. 2 represents a side elevation of it as seen from X in Fig. 1. Fig. 3 represents an enlarged detail section on the line Y Y in Fig. 1, showing the pivoted lever for carrying the cutter-block and heel-nailing device. Fig. 4 represents a detail sectional view of the cutter-block-holding device. Fig. 5 represents a detail longitudinal section of the heel-die and die-carrier. Fig. 6 represents an enlarged longitudinal section of the heel-nailing device. Fig. 7 represents a de tail plan view of the perforated nail-loader. Fig. 8 represents a plan view of the perforated loader-gate; and Fig. 9 represents an enlarged section on the line Z Z in Fig. 1, showing the spring locking device for the loader. I

Similar letters refer to similar parts wherever they occur on the diiferent parts of the drawings.

In the drawings, A is the frame or standard, in bearings in which is journaled the drivingshaft B, provided with fast and loose pulleys Z) b,as shown in Fig. 2. A rotary motion is imparted to the shaft B by means of beltpower applied to its pulley Z) in the usual manner.

On the shaft B is secured a pinion B, the teeth of which mesh in the teeth of the gearwheel 0, loosely journaled on the shaft 0. A rotary motion is imparted to the shaft 0 from the gear-wheel C by means of any wellknown clutch mechanism operated by the depression of the treadle-lever D, pivoted at d and normally held in inoperative position by means of a spring D.

I wish to state that I do not desire to confine myself to the use of an yparticular clutch mechanism, as any of 'the well-known forms may be used, by means of which a complete revolution is imparted to the shaft O by the depression of the treadle-lever D without departing from the essenceof my invention.

To the forward end of the shaft 0 is at tached a crank-pin c, journaled in a block 6, adapted to move in'a horizontal slot E in the lower end of the die-carrier E, which is thus made vertically movable in guides A A and A A secured to or forming parts of the frame or standard A. On the upper end of the die-carrier E is supported the heel-die E, which is secured in place on the said carrier, preferably, by means of lateral pressurescrews 6 e going through the sides of the upper portions of the carrier E, as shown in Figs. 1 and 2. A vertical np-and-down movement is by the means imparted to the heel-die and its carrier for every time the treadle-lever D is depressed. lVithin the heel-die E is arranged the vertically-adjustable nail-clinching and heel-regulating block f, having a downwardly-projecting shank f fitting into a vertical recess in the upper end of the spindle F, which is guided in bearing F. and E in the die-carrier E, as shown in Fig. 1.

The lower end ofthe spindle F is screwthreaded and made to pass loosely through the bearing E Above said bearing E is arranged upon the screw-threaded portion of the spindle F an adjustable nut F, by means of which the spindle F and its nailclinching and heel-regulating block f are made vertically adjustable, according to the thickness of the heel that is being made. Above the nut F is made fast on the spindle F a collar F, and between it and the upper end of the nut F is placed a yielding packing or cushion F for the purpose of allowing the block f to yield slightly downward in case the depth of the combined heel-lifts contained within the die E should exceedthe distance between the top of said block f and the upper cutting-edge of the heel-die E.

3 On two opposite sides of the die-carrier E are arranged shear-plates and heel-lift supports E -Ei upon which are placed the heelpieces which are to be trimmed off to a straight edge for the purpose of butting them agaist similar pieces, and to the frame A are secured the shears or cutting-knives A A opposite to the shear-plates E E, by which arrangement the heel -blanks are cut and straight-edged during the upward movement of the die-carrier E, as shown in Fig. 1. Above the heel-die is pivoted at a to the rear side of the upper portion of the frame or standard A the horizontally-swinging arm or lever G, which is bent laterally at each extremity to extend round to the front of the standard, and is provided in one end with a cutterblock and in its other end with a heel-nailing device, hereinafter to be more fully described.

The pivoted arm G has at one of its ends a vertically-perforated hub G, in which is journaled an internally-screw-threaded sleeve or nut G, having a flange or collar G at its upper end adapted to rest on the upper surface of the hub or hearing G, as shown in detail in Fig. l.

G is the cutter-block, preferably made of wood, which is secured in a suitable manner to the inverted cup-shaped block-holder G", having an upwardly-projeating screw-threaded shank G screwed into the nut G, by which arrangement the cutter-block and its holder may be adjusted vertically relative to the cutting-edge of the heel-die E". A setscrew G seeures the screw-threaded shank G to the nut G after such adjustment is made.

G is a handle on the hub G for the operator to take hold in swinging the block G into position above the heel-die E" during the operation of cutting the heel-blanks.

G is an adjustable stop-screw or projection on the arm G for the purpose of limiting the swinging motion of the said arm in thedirec tion shown by arrow in Fig. 3, which projection is brought in contact with the side of the standard A when the block G is swung to an operative position above the heel-die E", as shown in Figs. 1, 2, and

The opposite end of the pivoted arm G has a vertically-perforated hub or sleeve g, in which is arranged the driver-block holder g which is screw-threaded in its upper end and there provided with a nut g for the purpose of vertically adjusting the said driver-block holder relative to the sleeve g, according to the length of the nails that. are used for nailing the heels. I

g is the driver-block, secured in a suitable manner to the lower end of the holder 9', which drivenblock is provided with one or more drivers according to the number of nails used in nailing each heel.

g is a sleeve surrounding the sleeve g and adapted to slide up and down on the latter. The sleeve 9 is normally held in its lowest position relative to the sleeve g by the influence of a spiral spring 9 surrounding aguiderod 9 secured in its upper end to the arm G. The lower end of said spring 9 presses against an earor projection gon the sleeve 9, through which car the lower end of the guide'rod g passes loosely, as shown in Fig. 6. Bclowthe sleeve 9 is pivoted on the guide-rod g the perforated loader II, having one or more vertical perforations ll, corresponding in positions to the drivers ll" is a spring-pressed locking-pi n arranged in a recess on the side of the sleeve g", and adapted to enter a recess II on the loader II when the latter is swung into operative position below the drivers, and thus causing the said loader to be held in such position during the nailing operation. Below the loader H is pivoted on the guide-rod g the perforated gate or nail-dischargerl, having perforations 1 corresponding in positions to those of the loader-perforations II. A nut g on thelower end of the rod 9 prevents the said gateIand loader H from dropping oft said rod, as shown in Fig. 6. The gate I is limited in its swinging motion on the rod 9 relative to the loader H by means of a pair of stop-pins h and h, secured to the under side of said loader, as shown in Figs. 6, 7, and 8, for the purpose of preventing the nails from passing outthrough the loader-perforations until the nailing device has been swung into position directly above the heel-die.

I" is a projection or handle on the gate I for the purpose of swinging it against the stop projection h when the loader is to be filled, in which position the loader-perforations are covered by the solid portion of the gate I.

The loader is preferably charged with nails by an'attendant during the cutting operation of the heel-blanks, and this is done by swing ing the loader and gate to one side of the sleeve 9 and the nails dropped by hand into the loader-perforations, with the points of the nails resting on the non-perforated part of the gate 1, after which the filled loader and its gate are swung in position below the drivers, as shown in Fig. 6, with the points of the nails still resting on the non-perforated portion of the gate I.

g is a handle on the sleeve g for the operator to take hold of when swinging the nailing device into position directly above the heel-die E".

f is an adjustable stop-screw on the arm G, which is brought in contact with the side of the standard A when the nailing de vice is swung into operative position above the heel-die E, and when swung to such osition the gate I is brought in contact wit 1 a stationary projection a on the standard A or guide A, causing the said gate to be swung against the stop-pin h on the loader, thereby causing the gate and loader-perforations to coincide and allowing the nails to rest on top of the heel-blank contained within the heeldie E, which when moved upward by the crank 0, causes the gate and its loader to yield upward by the upward motion of the heelblank and causing the nails to be driven through the said heel-blank by means of the stationary drivers g and clinched again st the block f in the bottom of the heel-die E".

A in Figs. 1 and 2 is a forwardly-projecting support at the upper end of the frame A, beneath which the nuts G3 and g 011 the cutter-block and nailing device are respectively moved during the dieing-out and nailing operations of the heel, which support A serves for the purpose of relieving the arm G from upward pressure during the dieing-out and nailing operations, and transferring such up-- ward pressure caused by the upward movement of the heel-die and heel-blank, respectively, against the cutter-block and nailing device directly against the stationary support A on the frame A.

After the heel has been nailed, as above described, it is removed from within the die I, which is accomplished by means of a hand-lever K, pivoted at k to the frame A, and having its inner end adapted to come in contact with a projection or hub K, secured to the spindle F, as shown in Figs. 1, 2, and 5. It will thus be seen that by depressing the hand-lever K the spindle F and the heelsupporting block f will be raised sufficiently to push the heel upward and out of the heeldie E". As soon as the operator lets go the handle K it is automatically raised to the position shown in Fig. 1 by the influence of a suitable spring I allowing the spindle F and heel support f to drop to their original and normal working positions, as shown in Figs. 1 and 5.

The operation of the invention is as follows: The operator takes a pair of heel-pieces and places them on the shear-supports E E and starts the machine by depressing the treadle D, by which the die-carrier E is raised and returned to its normal lowest position, and during the upward motion of said die-carrier the heel-pieces held on the parts E E are cut and straight-edged by the action of the stationary blades A A The pieces so out are then butted together and placed on top of the die E". The machine is then started as before, causing the heel-pieces resting on the die E to be brought in contact with the under side of the block G by which the heel-blanks are cut out to the shape of the die E" and pushed into said die. This operationis repeated until the requisite number of heel-lifts have been died out and the die E filled, the upper heellift being made, preferably, to project slightly above the upper edge of the die. The operator then swings the block G4 out of position and swings the nailing device to the position previouslyoecupied by the cutter-block. The said nailing device having in the meantime been loaded with the requisite number of nails, the operator again starts the machine,

causing the nails to be driven into the heel and, if desired, clinched against the heel-support f. After the heel has been nailed the nailing device is swung out of position sufliciently to allow of the expulsion of the heel, which is done by depressing the handle-lever K. After the heel has been removed from the die E the cutter-block is again swung into position above the die E" for dieing out heel-lifts for the formation of heels to be nailed, and so on.

Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent and claim- 1. In a heel-making machine, the combination, with a standard, a vertically-movable die-carrier, and means for reciprocating the latter, of a heel-cutting die mounted on the carrier and having a top cutting-edge, a swinging arm pivoted to the rear side of the standard and having a laterally-bent extremity to extend round to the front of the standard and move in a horizontal plane above the heel-cutting die, a cutting-block mounted on the laterally-bent extremity of the arm, and means for. vertically adjusting the cuttingblockrelatively to the cutting-edge of the cutting-block, substantially as described.

2. A heel-making machine consisting of a standard or frame, a reciprocating die-carrier having a heel-die provided with a top cuttingedge, a vertically-adjustable spindle mounted on the die-carrier and provided at its upper end with a nail-clincher and heel-ejector located in the heel'die, and a horizontallyswinging arm pivoted on the standard or frame and having at one end a cutting-block provided with a screw-nut and screw-shank for vertically adjusting the cutting-block relatively to the heel-die, said heel-die acting by its top cutting-edge against the cutting-block to sever the heel-blanks and force them into the die, substantially as described.

3. A heel-making machine consisting of a frame or standard, a reciprocating die-carrier having a heel-die, a swinging arm pivoted on the frame or standard and provided with a pendent guide-rod and a nail-driver, a vertically-movable sleeve sliding on the guide-rod and having a loader pivoted on said rod, and a spring arranged on the rod and acting on the sleeve, substantially as described.

In testimony whereof I have signed my name to this speeification,in the presence of two subscribing witnesses, on this 5th day of August, A. D. 1890.
