HEEL=NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 398,846, dated March 5, 1889.

Application filed July 23,1887. Serial No. 245,040. (No model.)

of which the following is a full, clear, and e.

act description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention relates to a machine organized to fasten heel-seats, spring-heels, or low heels to the soles ofboots or shoes by a gang or group of fasteningssim ultaneousl y driven;

and it comprises various details of organization whereby a cheap and rapidly-operating 1 the slide bar or rod 0 the rod 0 will be drawn machine is produced.

In the drawings, Figure 1 is a view in vertical section of a machine having the features of my invention. 2 is a front elevation thereof. Fig. 3 is a section upon the lineocw of Fig. 2 and a plan view of the parts below i said line. fication.

' Referring to the drawings, A is the jack; a, the last or work support. ably, is adapted to be moved horizontally upon the bed a.

B is the templet. It is supported upon a lever or hinged plate, I, which is pivoted at it is rear end, I), to the standard or support 12 and is made vertically movable 'bymeans of the rod C, as hereinafter described.

E is a block supporting a gang or group of drivers, 6. It is mounted upon a block, 6, which is made vertically movable in the head or guideway e by the lever 6 which is pivoted to the standard or support 72 at c. It

The last, prefer- Figs. 4c and 5 show a slight modii slide-ba r c with a flange or head, 0 and the rod G with a yoke, c", the arms of which extend by the head 0 and are turned inward upon the slide rod or bar 0*. (See Fig. 1.) This provides the slide bar or rod 0 with a movement on the end of the rod C, which movement, however, not communicated to the rod C, unless the slide-block D is caused to be inserted between the upper surfaces, d, of the horizontal section of the yoke c and the under surface of the head 0 when the head is in its highest position, or in the position represented in 1. At that time the block D, which is made in two parts, (Z d,

' (see Fig. 1,) can be moved between these two parts, and upon the downward movement of downward. The slide bar or block D is moved into place by the lever (Z which is pivoted at (1*, and it is automatically disengaged upon the upward end of the stroke of the slide bar or rod 0 by means of the spring (1 The rod C is connected by a pin, 0, directly to the lever 6 back of its front end or point where it engages the slide-block e. The rod C is connected with the templet-lever b in a I manner to permit the rod to be moved to is also operated by the rod 0. The rod 0 is 5 templet, the rod C is moved downward, there- 0' is made separate from the rod 0, and is 1 adapted to be connected and disconnected therewith, in order that the shaft 0 may be constantly rotated, without, however, imparting movement to the drivers and the templet B except when desired. The connection between the rod C and the slide bar or rod 0 is represented as obtained by providing the l l l some extent in relation to the lever without actuating it. This connection I have represented as obtained by forming a hole in the lever or pivoted plate I), through which the rod C extends, and mounting a spring, a between a collar fixed to the rod and the upper surface of the lever or plate, and a spring, 0

between the lever and a collar fixed to the rod below it.

In opera-tion the block D having been moved by the lever into position to cause a reciprocation or movement of the block c and the by drawing the templet B with it until the templet comes into contact with the upper surface of the sole or with the heel blank placed thereon, when it comes to a rest, but the rod C continues to move, drawing the block 6 downward, causing the drivers to en ter the holesin the templet and drive the nails therefrom into the heel and soles of the boot or shoe.

In lieu of the construction above described the templet-lever b and the lever a to reciprocate the block carrying the drivers, may be pivoted, respectively, at the points f, (see Fig. 4,) and the power for operating them applied at their ends. This power may be by means of a rod and cams such as I have already described, or by means of the camsf f as represented in Fig. at. The cam f in this "form of construction operates the lever by means of its cam-groove anda cam-pin on the end of the lever, which enters the groove, and

To the cam f operates the lever 17, the lever havi ing a cam-pin, which enters a cam-groove in the cam-disk. A lever for thus operating the templet is described in my former applica tion. 7

Figs. 4: and 5.)

For loading the templet B, I use a movable loader, G, such. as represented in Fig. 3, and movable laterally from one side of. the templetinto; position over the templet to deliver,

The machine provides a simple, compact, and cheap organization for nailing heel-seats, spring-heels; or, attaching low heels, or heels that" do not require to be pricked or. very 4o much compressed before attaching.

The drivers then lift,
