HEEL-NAILING MACHINE.

- SPECIFICATION forming part of Letters Patent No. 461,448, dated October 20, 1891.

Application filed July 1, 1887. Serial N0.243,084. (No model.)

T0 at whom it may concern:

Be it known that I, FREEBoR-N F. RAYMOND, 2d, a citizen of the United States, residing at Newtornin the county of Middlesex and State of Massachusetts, haveinvented anew and usef ul Improvement in Heel-Nailing Machines, of which the following is afull, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The inventionis an improvement upon that described in the patent to Henry A. Henderson, No. 3163M; and it comprises a heel-at -machine having the features of my invention. Fig. 2 is a view in vertical section upon the dotted line m 00 of Fig. 1, and in plan of the parts below said line. Fig. 3 is a view representing in front elevation and in section the parts in, a ,difierent position from that represented in Fig. l. Fig. 4 is a view in elevation and section of the parts represented in Fig. 3, showing them in still another position. Figs. 5, 6, 7, and 8 illustrate in elevation and section modified forms of the invention.

Referring to the drawings,A is a cross-head, which carries the rotary head a. This IO- tary head has a compressingarm A, an arm a, carrying a gang or group of awls a an arm a carrying a gang or group of drivers a, an arm a carrying a top-lift spanker and preferablya top-lift-holding device a. The cross-head A preferably is reciprocated as described in said Henderson 'patentnamely, by means of a crank and pitman, a lower cross-head upon which the pitman acts when it is desired to depress the upper cross-head, and connecting-rods connecting the lower cross-head with the upper cross-head. This construction is fully described in the patent The parts of said mechanism referred to.

levers e e.

are like those described in said patent, with the exception that the upper part of the post D, upon which the table is vertically movable, is cylindrical in shape and the table has the cylindrical. sleeve (P, which surrounds the post.

E is the heel-compressing device. It may consist of two plates or levers e c, which arepivoted at e to the tabled beneath the templetplate, or they may be separately pivoted to the table, or the plates may have a horizontal sliding movement.

Each plate or lever c e supports a section of the heel-compressing device, the lever or plate e supports the section E, and the lever or plate 6 the section E Each of'these sections is represented as formed from one block of metal and as having the compressing-surface e of the shape which it is desired to give the side wedge of the heel. They, however, may be made in two or more parts, it desired. They are also made movable from their holding plates or In Figs. 2 and 7 I have represented the holding-plate levers'as having a shoulder e and dowel-pins c and the dieblocks E E as having extensions e and dowel-pin holes 6 The extensions rest upon the shoulders e and the dowel-pins fit the holes 6 In Fig. l I have represented the levers or plates 6 e as each provided with a dovetail recess, which receives the dovetail tongue upon the upper edge of each die-block, the die-blocks being fastened in place to their respective plates or levers by a screw or in any other suitable way. The plates or levers e e are extended forward from the blocks E t E any desired distance, and their ends are located to be closed or moved toward each other by the cross-head and a connecting'operating, medium or device.

There are a numv ber of ways by which these levers or plates can be provided with a closing movement to move the lever 01' plate 6, carrying thedieblock E In this form of the invention the templet is given a vertical movement in relation to the last or work-support, and the die-block supports are mounted upon the table supporting the templet and moved vertically therewith, and as it is desirable, although not essential, that the die-blocks E E be opened before the attachment of the top lift, I have represented the levers F F as placed so that they shall not operate to move the levers or plates *6 e, excepting when the table carrying them is being depressed or while it is depressed. To accomplish this result, the le vers are shaped and pivoted substantially as represented in Fig. 1, the lever F being pivoted at f and the lever F being pivoted at f Each lever carries at its lower end a camroll f and at its upper end a roll f There is alsoa stop f for limiting the extent of the downward movement of the cam-roll f and a spring f for returning the lever to its normal position. WVhen this form of construc tion is employed, each plate or lever e c has the bearing-section f upon its outer edge in line with the cam-rollf", and upon which the cam-roll acts. It is made of any desired length, and it may have any desired incl-ination in relation to the cam-roll f. The crosshead A has blocks A preferably verticallyadju'stable, which are arranged to come in contact with the rolls f of the lovers F F.

In operation, the boot or shoe having been placed upon the jack and the jack moved into operative position between the compressingblocksE E (see Fig. 1,) the templet is moved downward by hand to clamp the heel-blank upon the outsole of the boot or shoe. This downward movement of the templetis caused by moving the table d, which operates it downward, and this causes the bearing-surfaces f of the plates 6 e to come into contact with the cam-rolls f which are then stationary, and the plates are thereby caused to be closed or moved toward each other during the downward movement of the templet, and the working surfaces of the die-blocks are moved toward the side surface or edge of the heelblank, so that upon the end of the downward movement of the templet the side-compressing blocks E E have also been moved simultaneously inward to or toward the side surface of the heel-blank, and the heel is held confined upon the outsole by the templet and by the compressing-blocks E E The compressing-blocks also serve by this movement to accurately center the heel-blank in relation to the heel-seat of the boot or shoe. The positions of the parts are then as represented in Fig. 3. The machine is then set in operation, and the cross-head A makes one reciprocation, and at the beginning of its downward movement, before the points of the awls have entered the heel-blank, the cross-head A comes in contact with the rolls f and the upperends of the leversF F are moved downward and the cam-rolls f upward upon the bearing-surfaces f of the die-holding plates. This causes the plates 6 e and the compressing-blocks E E to be moved forcibly toward and upon the side surfaces or edge of the heel-blank, and the degree of this lateral compression is varied, of course, by the extent of movement of the plates or levers e e. This is governed by the inclination of the bearingsurface f and the extentof movement of the cam-rolls f thereon. As above stated, the surface f may have any desired inclination. The distance which the cam-rolls travel may be adjusted by adjusting the height of the blocks A ter the heel-blank and form the holes therein, and the awl-block comes into contact with the upper surface of the templet, forcing it downward and completing the compression The awls then immediately enof the heel-blank by direct vertical pressure 7 the boot or shoe to which it is to be attached,

and also the formation of the holes in the compressed heel-blank while it is under powerful compression and while it is held compressed upon the sole of the boot or shoe to which it is to be immediately attached. This is very important in attaching what is known as pieced heels, because it provides for forcing together the parts or pieces of each lift of the heel tobring their adjacent surfaces into solid contact with each other upon the sole of the boot or shoe to which they are to be attached and before the holes for the attaching-nails are made, and holds them in this compressed condition and position while the holes for the reception of the attaching-nails are being made, and also while the attachingnails are being driven, uniting the pieces which form the heel-blank together and to the soles of the boot or shoe while they are held compressed or forced into contact with each other.

It will be observed that as the side compressors or blocks E E are moved or operated to compress the heel-blank laterally be--.

fitting of the blank to the sole and the proper I have represented in Figs. 5 to 8, inclusive,

- which are like those shown in Fig. 2.

'ment of these slide-bars the inclines are moved into or out of contact with the ends of these levers or plates and either cause them to be moved toward each other or to be opened by their respective opening-springs,

I prefer that these bars be not rigidly secured to the cross-head, although in some instances they may be. Each bar preferably is supported by the side section of the frame and is extended downward and connected with the cross-bar g, which is connected with a treadle g by a rod 9 (see Fig. 7,) in order that the barsmay be drawn downward after the downward-movement of the templet and before the machine is operated, so that the inclines may be moved against the levers or plates 6 e and close them upon the side surfaces or edge of the heel by hand before the machine is operated by power. are locked in this position by means. of the ratchet-bar g", which extends upward through a hole in the bed I) and has the ratchet-teeth 9 which are adapted to be engaged by the latching-lever g. Y This latching-lever is pivoted at 9 and has the rear handle 9 the front handle g, (see Fig.8) and a spring 9 for holding its locking-edge in contact with the ratchet-bar g to automatically engage its teeth. Upon the downward movement of the cross-head it comes in contact with the upper ends of the bars and moves them still farther downward, causing the inclines g to move the levers or plates forcibly or with pressure toward each other to compress or solidify the side or edge of the heel.

.The actuating-surfaces of the bars maybe so shaped as tocause them also to operate to lock the levers or plates 2 e at the end-of their inward or compressing movements. This is accomplished by forming upon the bars straight surfaces in continuation of the inclined surface g, so that the inclined surfaces pass or are movedby the levers or plates and the straight surfaces of the bars brought against or behind them, or, in other words, so that the front ends of the plates or levers rest against the straight surfaces of the bars. (See Fi 6.l

l prefer that the connection between the cross-head and the bars be a loose or free connection in order that the head A may be reciprocated to spank or attach a toplift to the compressed and attached heel without actuating or moving the levers or plates e, because on account of the position of the table sup-- The bars porting the templet and the plates or levers atthat time it is desirable that the plates or levers 6 should be held wide open during the reciprocation of the top-lift attaching and spanking block; and this loose orifree connection I have represented as obtained by means of the slide-blocks H, attached to the 7 head A in a manner to be moved horizontally in ways thereon from a position immediately over their respective bars to a position to one side thereof, so that the head A communicates motion to the bars only when the slide-blocks are in position over their upper ends or in, line with them, and when moved out of line with them the head reciprocates without communicating movement to the bars.

I11 operation the boot or shoe is mounted upon the last or work-support and moved into operative position. The templet is moved ative position over the heel end of the jacked boot or shoe. The heel-blank is placed over the heel end of the shoe, and the table supporting the templet and side-heel-compress outward from its table or support into opering devices is moved downward by the hand -lever,'as described and shown in said Henderson patent, bringing the templet into contactwith the upper surface of the heel-blank, and the side-compressors, by the movement of the; treadle g are brought into contact with the edge of the heel and accurately center it in relation to the heel-seat of the boot or shoe. The awls having been moved into operative, position, the machine is set in operation, and the side-compressors are caused to be set or moved by the movement of the bars G with any desired force or pressure against the side Y surface of the heel, molding its edge to any desired shape, and,if a pieced heel is used,setting the pieces of the blank firmly and solidly together, and also forming the heel to the curved, bottom of the last and of the outsole or heelseat. This is immediately followed by the entrance into the heel-blank of the awls,

which form the guiding-holes for the attaching-nails, and the coming in contact of the, under surface of the heel-blank with the upper surface of the templet, which causes the templet to be moved against the upper sur-, face of the heel-blank forcibly and to compress it by vertical compression, and the sidecompressors are still farther closed or forced toward each other during this downward ver-, tical movement of the templet, so that the compressors upon their first forcible inward movement are not forced upon the edge of the heel-blank with sufficient pressure to prevent them from being moved downward and inward simultaneously 'with the downward movement of the templet. Of course the extent of the downward movement of the. tem- ITO plet is varied according to the extent of the side compression of the blank before the blank is brought into contact with theupper 3 surface of the templetthat is, when the side-f;

other, or they may be partially released, ac-' cording to the character of-the work and the results desired, by varying the shape of the actuating-surfaces g.

The templet is automatically locked in its lowest position, and the awls having been withdrawn the attaching-nails are fed by the nail-carrier to the templet and the drivers brought into position. If the side-compressors have been released upon the upward movement of the cross-head, they are upon the downward movement of the drivers again brought into contact with the edge of the heel, so that the heel is held compressed by them while the nails are being driven into the heel and soles of the boot or shoe. If the heel is to be spanked, or if a top lift is to be attached and spanked, the table is then released and moved forward, carrying with it the templet and side-compressors. compressors are automatically opened or moved by their operating-springs, and if the bars G are used the operator moves the connecting -blocks H, thus disconnecting the cross-head from them. If the construction represented in Fig. 1 is used, then the levers will be moved by the head without operating the plates or levers'e e, as they are then above the line upon which the levers move.
