HEEL-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 271,117, dated January 23, 1883. Application filed September 11, 1882. (No model.)

I 0 all whom ti may concern:

Be it known that I, FREEBORN F. RAY- MOND, 2d, of Newton, in the county of Middlesex and State of Massachusettahave invented a certain new and useful Improvement in Heel- Nailing Machines, of which the following is a full, clear, and exact description, reference betionof the templet-plate. Fig.4 shows a vertical section of a modification of the invention, hereinafter described; and Fig. 5 is a plan view thereof.

This invention is an improvement upon that described in Letters Patent No. 252,215and No. 259,687; and it consists in a templet having means for holding the nails, whereby a separate nail holder or loader is dispensed with.

Referring to the drawings, A represents the templet. It has horizontal and vertical movements like those'described in the said Letters Patent. Preferablyitis made in two horizontal sections, a a, between which is interposed an elastic diaphragm, a preferably of rubber. This diaphragm, being elastic, permits the awls in their downward movement thronghthe templet to press it horizontally from the line of the templet-holes, and upon their withdrawal the diaphragm resumes its original shape, closes the holes in the upper section, and furnishes a rest, through which the nails are subsequently driven by the driver, the diaphragm again opening and closing the holes, as before. I prefer that either one or the other of the sections be recessed to receive the diaphragm; but of course it may extend to the edge of the templet, if desired. It is desirable that the rubber should be tightly confined and even compressed between the two sections, and it is also desirable that the portion of the templet above the diaphragm be higher than the height or length of the nails used. The two sections may be united by screws or in any other suitable way.

In operation, the templet-plate A is moved to bring the templet over the heel, the awls driven, and holes in the. heel formed. The

templet is then withdrawn'and loaded with into position over the holes, when the drivers descend and the nails are driven from the templet into the heel. The rubber diaphragm, owing to its elasticity. closes over the holes made by the passage of the awls and nails and drivers, and serves to hold the nails in the templet-holes, and it will act to better advantage ifit is somewhat compressed. The under plate of the templet should be sufficiently solid to stand the pressure to which it is submitted in compressing the heel.

If desired, the templet-plate may have two templets, one at each end, and may be pivoted to the templet-table at the center of its length,

so that while one templet is being used. in connection with the awls for formingthe holes the assistant may be loading the other templet, and upon the upward movement of the awls the templet-plate be moved upon its center, and the loaded templet substituted for the unloaded, and the nails driven therefrom into the heel upon the descent of the drivers. This construction is shown in Figs. at and 5. The advantages of this construction are simplicity of construction and operation, and cheapness, in that the nail holder and loader is entirely dispensed with.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States- 1. In a nailing-machine, a templet having at or near its bottom a diaphragm of elastic material. as and for the purposes described.

2. The combination, in a templet, of the sections 0. a and the interposed elastic diaphragm a as and for the purposes described.

3. In a heelnailing machine, in combination with hole-forming and nail-driving mechanism, two templets, one of which is adapted to be used in connection with the awls in forming the holes and then to be removed to give place to the other, which is adapted to receive and transfer then-ails into position to be driven by the drivers, all substantially as and f or the purposes described.

4. In a heel-nailing machine, in combination with the hole-forming and nail-driving mechanism, two templets adapted to be interchanged in position, whereby one maybe used with the ed to be used. interchangeably of successively awls and the other to receive, transfer the with the same group of drivers, all substannails, and coach with the drivers, all substantially as described.

tially as described. F. F. RAYMOND, 2D.
