HEEL-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 410,677, dated September 10, 1889.

Application filed December 16, 1836- Serial No. 221.702. (No model.)

To all whom it may concern.-

Be it known that I, FREEBOEN 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 eX- act description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention relates to a heel-attaching machine having heel-edge molding or forming devices for forming or molding the edge of the heel before it is attached to the soles of the boot or shoe.

It further relates to mean s for automatically feeding heel-blanks to the said heel-forming devices and for transferring them therefrom to the heel-blank-attaching devices.

It further relates to various details of organization and construction, which will hereinafter appear.

In the drawings, Figure 1 is a view in vertical cross-section of a machine containing the features of my invention. Fig. 2 is a view in vertical section taken from front to back of the machine to further illustrate its construction and operation. Figs. 3, Al, and 5 are detail views.

A is the cross-head, and a the revolving head, which is adapted to be automatically revolved, and which has an arm carrying a gang or group of awls, another arm carrying a gang or group of drivers, and still another arm carrying a top-lift-breasting device.

A is the templet; A the nail -carrier; A the last or work-support; a, the jack; a the spindle or rod supporting the work-support; A*, the toggle-head, which is operated similarly as described in my previous inventions.

A is the top-lift-carrier plate, which is in all material respects like that described in said previous inventions, which receives top lifts and is adapted to be operated as therein described.

A is the heel-blank-transferring plate. It is also substantially like that described in said inventions, and is operated or moved substantially as therein specified.

The heel-blank-edge molding or forming devices comprise a pocket B, which is arranged below the level of the heel-blank-t-ransferring plate A, and which is formed by the movable head I) and the horizontally-moving forming-jaws Z) 11 b The heel-blank is fed to the pocket B when the heel-blank-transferring plate A has been moved inward to transfer or move a heel-blank under the templet, and I prefer to hold the heel-blanks in stack in the box 0 and to feed them one by one to the pocket 13 by the carrier 0, which is operated at intervals to transfer a blank from the stack to the pocket, as described in my said inventions.

The forming-jaws 'b' b b b are adapted to have radial movements, or movements substantially radial, and upon a substantially horizontal plane, and they are operated to close simultaneously upon the vertical edge of the heel-blank and to compress it solidly by lateral presssure against the front wall I) of the pocket. I have represented the side pressers as provided with these movements by means of the levers B B B B the lever B carrying the jaw Z), the lever B carrying the jaw b the lever 13* carrying the jaw b and the lever B carrying the jaw b. Each jaw, preferably, is attached to its respective lever by means of a dovetail joint, and so as to be readily removed therefrom, (see Fig. 4,) and each is locked in place by alocking-screw Each lever is pivoted to a support or arm at b, and the lower ends of the levers carry rolls b which are adj ustably secured to the ends of the levers and are arranged to bear upon the inclined surfaces 17 of the slide-head D, so that upon an upward movement of the slide-head D the jaws are caused to be closed or moved inward. Upon the downward movement of the slide-head D the jaws are opened by the springs b,which bear against the outer edges of the lever.

The slide-head D carries the lower head or heel-seat former b, and it is provided with a vertical movement, preferably by means of the cam-lever E, which is pivoted at e, and has the cam-groove e,wl1ich receives the cam-pin e extending-from the slidehead. The lever also has the arm 6 which is adapted to be moved by a cam-groove e in a cam-disk e upon the camshaft e or by an eccentric on the crank-shaft. (Not shown.) It will be seen that by this construction the upward movement of the slide-head D, and consequently of the lower head 1), upon which the heel-blank is fed from the stack, causes the heel-blank to be moved upward, and at the same time the jaws to be closed upon its edges with very great pressure, and at the same instant another head F, attached to or carried by the cross head A, moves downward, and its under surface enters the space between the jaws and acts as an abutment to resist the upward thrust of the lower head I), so that the heel is molded not only by lateral pressure exerted against its side edge, but also by vertical pressure exerted against its under surface, and it is thereby not only compacted very solidly, but is also brought to a molded shape, I

or a shape which approximates the shape of the finished heel.

This treatment of the heel-blanks is especially applicable to heel-blanks made from pieces, or-known as pieced heels.

The extent of the inward movement of the jaws b b b b is varied by means of the ad j ustable rolls b at the lower ends of the operating-levers. If the rolls are set out in re lation to the ends of the levers, then the jaws are moved inward. If they are set closer to the ends of the levers, then the jaws are not moved inward so far, and in this way adj ustment to varying sizes of heels is obtained.

After the heel has been formed it is necessary to remove it from the jaws, in order that it may be carried or transferred to the heelattaching devices. This is accomplished by making the lower head I) movable in the slidehead D, so that upon the downward movement of the slide-head 1D after the compression of a heel-blank and the opening of the jaws b b b b the head I) is caused to be moved upward between the jaws to move the heel-blank above the upper level or surface of the jaws, and so as to be taken by the transferrer-plate A and advanced to the heel-attaching devices. This movement is given the head I) by means of the rod G, which is provided witha vertical movement in the slide-head D and to the end of which the head I) is attached, and also by means of the lever g, the end g of which receives the lower end of the rod G, and at its opposite end to a rod giwhich connects it with a cam g The cam is so timed as to cause the rod G, and therefore the compressed heel, to be lifted immediately before the transferrer A is caused to be moved forward to feed or transfer the heel-blank.

In use the heel-blank is fed from the stack or receptacle to the heel-molding devices and the heel-molding devices then caused to be operated to mold the heel-blank. These operations are proceeding simultaneously with the attaching of a previously-molded heelblank to the soles of a boot or shoe. The molded heel-blank is then moved from the molding devices to the transferrer, which engages it and feeds it.

The advantages of the invention arise from the fact'that the heel-blank is molded immediately before it is attached to the soles of the boot or shoe to which it is to be secured and as an automatic operation, the heelblank being delivered to the molding devices and molded and then transferred to the heelattaching devices and attached automatically or without handling.

I am aware of Patents No. 112,702, to Glidden, No. 153,360, to McKay and Fairfield, and No. 246,945, to Fischer; but I consider that these patents do not contain the features of myinvention, because they do not describe the embodiment in an organized nailing-machine of these elements-namely, a heelcompressing device for molding the side edge of a heel-blank and a heel-attachin g device for attaching the molded heel to the soles of a boot or shoe adapted to have conjoint and simultaneous act-ion upon two distinct heelsand because they do not show, n connection with these appliances arranged 1n an organized machine for conjoint action, the heel blank feeding mechanism adapted to feed heel-blanks to the heel-edge-molding devices and transferring mechanism adapted to carry the molded heel-blank from the moldin g devices to the heel-attaching devices.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States- 1. In an organized heel-nailing machine, the combination, with heel-attaching devices, of a heel-blank-edge molding or compressing apparatus consisting of vertical and lateral formers or pressers from which the blank 1s automatically transferred to said attaching I devices connected substantially as described and automatically operated, and thereby adapted for conjoint and simultaneous use, one to mold the side edge of a heel-blank: and the other to attach apreviously-molded heelblank, substantially as described.

2. In a heel nailing or attaching machine, the combination of a heel-blank-edge molding or compressing apparatus, a heel-blank carrier for feeding the heel-blanks thereto, a device for transferring a molded heel-blank from the compressing apparatus to the attaching devices, the said attaching devices and connected mechanism, substantially as described, for. simultaneously and automatically operating the several parts, as set forth.

3. In a heel-nailing machine, the combination of the jaws b b b 19 the plate b and the head I), substantially as described.

4:. In a heel-nailing machine, the combination of the jaws b b b 5 their levers B B B B pivoted as described, the slide-head D, the head I), and the wedge or inclined surfaces 12 upon the slide-head, against which the ends of the levers are held in contact, substantially as and for the purposes described.
