HEEL-MAILING MACHINE.

SPECIFICATION forming part of Letters Patent. No. 377,172, dated January 31, 1888.

Application filed November '2, 1887.

To all whom, it may concern.-

Be it known that I, FREEBORN F. RAYMOND, 2d, of Newton, in the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Heel-Nailing Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention relates to a heclnailing machine provided with a solid die for centering the heel-blank and for shaping and compressing its side surfaces by lateral pressure during the attachment of the heclblank to the soles of the boot or shoe.

The invention is illustrated as applied to a National heel-nailing machine.

In the drawings, Figure l is a view of a part of the National machine, part in front cleva tion and part in vertical section, provided 'ith my improvement. Fig. 2 is a view in plan of the table supporting the die, templet, and nail-carrier, and in horizontal section of the frame of the machine upon a line immediately above the surface of the nail-carrier. Fig. 3 is a view of the parts represented in Fig. 1 at the completion of the compression of the heel-blank. Fig. 4 is a detail view illustrating the application of a top lift to the compressed heel-blank. Figs. 5 and 6 are detail views of the solid die.

Referring to the drawings, A is the crosshead of the machine. It is provided with a reciprocating movement, substantially as de scribed in the Henderson patent, No. 316,894, and it carries a rotary head, B, having four armsfirst, the arm a, having a pressureblock, a; second, the arm (4", having a block, a, carrying a gang or group of awls, A; third, an arm, a, carrying a block, a supporting a gang or group of drivers, a; fourth, an arm, a, supporting a block, a carrying the toplift holder and forming atop lift spanker.

B is a vertically-movable table. It is like that described in said Henderson patent, excepting that it has forward-extending sections 1), which furnish the recesses b for the solid die-block G, and also an additional support for the templet D when in operative position. This additional support is obtained by the extension of the cap-plates at. These capplates heretofore have not extended beyond the edge Serial No. 254,039. (No model.)

of the templct when drawn back. Conscerative position, was supported at its rear end only, and was not supported by cap-plates extending from its sides. The templet D is horizontally movable in the table.

D is the naitcarrier. This is also horizontally movable on the tcmplet-platc, and is held in position thereon by the cap-plates d. The die-block O is of metal, and has the die-cavity (1 formed therein, the side surface of which above the sole-line (indicated by Fig. 6) is of the shape which it is desired to give the side surface of the hecl-blank. Below the dotted line the die flares outwardly to provide a full entrance for the heel-blank to the die. The die is cut away at its front to provide a recess or space, 61*, for the sole of the boot or shoe, as upon the application of pressure to the heelblank the die is moved downward and its sides and back caused to extend below the level of the ontsole. The die-block 0 preferably is held in place in the table B by means of a spring-pin.

In operatiogi the heel-blank is placed bcncath the die-cavity and partially inserted therein, the jack carrying the boot or shoe moved into position beneath it, the tcmplet moved out into operative position to cover the upper opening, (i to the die, and the table moved down by the hand-lever described in said Henderson patent. The pressure-block at having been moved into position, the machine is caused to make one reciprocation. This brings the pressureblock into contact with the t'emplet-plate and moves it downward, also causing the table B to be moved downward and the die 0 to be forced upon the heelblank and to form or shape its side surfaces and to support them while it is being vertically compressed between the templet-plate and the upper surface of the last or work-support E. The table is automatically locked in its lowest position, as described in the said Henderson patent, at the end of the downward movement of the pressureblock, and it is then turned out of operative position and the awls moved into operative position. Themachine is again operated and the awls reciprocated and holes punctured in the compressed heelblank. The machine again comes to rest, the awls are moved out of operative position i and the drivers into operative position, the

quently the templet, when forward in its opattaching-nails are fed to the templet by means of the nail-carrier, and the machine again caused to make a reciprocation, and the attaching-nails are driven into the heel and soles of the boot or shoe, and, if the heel is to be blind-nailed, are left protruding from the upper surface of the heel-blank. The table B is then released or unlatchcd and allowed to be moved upward sufficiently to disengage the die and templet from the heel-blank, and the templet is then moved backward and the top-lift spanker and holder moved into operative position. The lift having been placed in the top-lift holder, the machine makes another reciprocation, and the top lift is-spanked upon the protruding ends of the attachingnails.

The top lift, of course, must be a trifle smaller than the upper opening, d, of the dieblock. I

It will be seen that upon the backward movement of the templet-plate the upper surface of the inverted heel is exposed in the die for the reception of the top lift, and that upon the downward movement of the top-lift spanker the table and die are caused to be again moved downward in relation to the heel-blank.

The die 0 may also be used for centering heelblanks formed in any other heeLblank-fOrming machine, as well as for centering ordinary or unformed heel blanks for flush-nailing, in which case the die may be made shorter or with a die-recess of less depth than that herein described.

I would say that the mechanism herein described may be used for shaping and compressing heel-blanks without attaching them to the soles of a boot or shoe, if desired, in which event the templet-plate D may be stationary, or may be entirely dispensed with andthe pressure-block a be made sufficiently long to come in contact with the die-block G and close its upper opening, d upon its downward movement.

I would also say that the dieblock O is removable from the table, in order that the dieblocks having die-cavities of different shapes may be substituted.

I would say, also, that the heel-blank may be compressed by the die and solidified and 21, 1874, which describe the use of various forms of dies; but none of these patents shows a heel-nailing machine adapted to attach a heel-blank to the soles of a bootor shoe, and none of them shows a solid die which is closed by a horizontally-movable templet, and which die, aside from its vertical movement, is stationary during the pricking of the holes and Having thus fully described my invention,

I claim and desire to secure by Letters Patent of the United States-;

In a heel-nailing machine, the combination of a reciprocating head, a rotary head supported thereby, havingan arm carrying a pressure-block, an arm carrying a gang of awls, an arm carrying a gang of drivers, and an arm supporting the toplift spanker, which are adapted to be brought successively into operative position, a last or work-support, a vertically-movable table, a solid die -block having a die-cavity, supported by said table, the sliding templet-plate D, and nail-carrier D, substantially as described.
