LASTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 236,220, dated January 4, 1881.

Application filed December 2, 1880. (ModeL) To all whom it may concern:

Be it known that I, LoUIs GoDDU, of Winchester, county of Middlesex, State of Massachusetts, have invented an Improvement in Lasting Devices, of which the following description, in connection with the accompanying drawings, is a specification.

This invention relates to a lasting device for lasting boots and shoes by hand.

My invention consists of a light easily operated hand-tool provided with upper-engagin g portions (shown as points or prongs) to enter and enable the edge of the upper to be drawn over the edge of the inner sole, and having, also, a driver and feed-bar in one piece, adapted to drive string-nails and cut them off.

Figure 1 represents, in side elevation, a lasting-tool constructed in accordance with my invention, and Fig. 2 a section thereof at the rear of the driver-bar.

The frame-work of the machine (shaped as shown) is suitable to be grasped in the hand of the operator, his thumb entering the opening 1). The front part of the frame is bifurcated or slotted to receive the driver-bar 0, having a head to be struck by a hammer, pinchers, or other suitable instrument held in the other hand. At the lower end of the bar 0 is the rod 11, adapted to both engage the heads of the string-nails e, and feed the same forward to drive them into the upper and inner sole, and also to sever the nails from the string of nails just as they are driven.

The reel f, for holding the string of nails, is

mounted on the axle 9, supported in an arm, h, of the frame a, and the nail-string e, supported in the yielding rest at the end of the sprin g j, is led through the guideway made for its reception in the frame-work a, one side of the said guide supporting the smooth side of the nail-string, as in Fig. 1. Retrograde motion of the-nail-string is obviated by the stopspring or detent-pawl Z. The driver-bar c is lifted by a spring, m, which also acts upon the said bar, which is free to move to a certain extent toward and from the nail-string, and keeps the rod d in contact with the string-nails.

The upward motion of the bar 0 is checked by the end of the adjustable screw n, clamped between the screw-threaded checks 2 3 of the bifurcated frame by a screw, 4, the screw it also controlling the inward position of the driver-bar, so that it may be placed ata greater or less angle of inclination with reference to the block r.

The front edge of the bar a is provided with a shoulder or projection, 5, which, just as the lower end of the rod 61 comes opposite the cutting-lip 7, during the downward movement of bar 0, strikes the bar-moving surface, shown as a roller, 19, on the fixed stud 6, thereby causing the inner edge of the lower end of the rod 01 to co-operate with the said lip or edge 7 of the steel block 1, over which the nail-string is moved or fed by the rod 01, and sever from the string the nail just driven. The lower end of this block 1' is provided with prongs 8, which the operator thrusts into the edge of the upper being lasted, said prongs enabling him, to a greater or less degree, to draw and strain the said upper over upon the inner sole on the usual last.

If it is desired to draw the upper over the inner sole with more force than is practicable with the prongs 8 alone, then in such case the edges of the upper may be grasped between jaws of hand-operated pinchers, such as are now commonly used in hand-lasting, and when drawn into position by the said pinchers held, say, in the right hand of the operator, the prongs 8 may be made to catch into the edge of the upper and hold it in position on the inner sole while the driver is struck by the pinchers to drive a nail into the upper and inner sole and cut it off.

I do not broadly claim a hand-mailer to drive string-nails; nor do Ibroadly claimthepoints 8.

The frame a has a controlling projection, 00, against which the fingers act to maintain the frame in proper upright position when the hamlet the operator is closed. The tool bein g supported chiefly by the thumb of the operator, his fingers are left free to manipulate the edges of the upper and lining preparatory to the introduction of the prongs 8 therein and the driving of the lasting-tacks.

I claim 1. In a nailing-tool adapted to be held by hand, the loosely-held driver-bar 0, provided with the rod (1, and the roll or surface 19, combined with the frame provided with the guide-- way and rest for the smooth side of the stringnails, and the block 0', provided with lip 7, substantially as described.

2. [he bifurcated frame, its threaded ears 2 3, screw n, and clamp-screw 4, combined with the driver-bar 0, to operate as shown and described.

3. The herein-described lasting-tool, having a frame-work shaped to be held by hand, and provided with the guideway for the stringnails, and the block 9', and prongs 8, combined with the loosely-held driving-bar, and rod d, shaped as described, to engage the heads of and drive the nails of the string, and to sever the driven nail from the said string, substantially as described.

4. In a hand-nailing tool, the frame-work (I, provided with a thumb-receiving opening, I), and a controlling projection, 0:, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of twoisubscribihg Witnesses.

LOUIS GODDU.
