Application filed July 18, 1901l Serial No. 68,769. (No model.) l

To all whom it may concern;

Be it known that 1, MICHAEL F. KELLEY, of Milford, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Lasting Machines, of which the following is a specification.

This invention has relation to lasting-machines, and more particularly to that class of machines wherein the upper is secured to the insole by suitable fasteners. In such machines considerable diiiculty is experienced in lasting the heel portion of the shoe, owing to the fact that the usual pincers are thrown out of operation at such times or are not used, and consequently the upper is not laid tightly over and caused to conform to the counter, so as to form a perfect heel-seat.

The object of this invention, therefore, is to provide a mechanism applicable for use in such machines for hammering the upper around the back of the heel portion of the shoe to cause it to lie perfectly flat against the counters and last, so that when the upper is secured to the insole it will'be stretched tightly and be free from bunchy spots or slack places.

Referring to the drawings, Figure 1 represents in side elevation a portion of a lastingmachine equipped with my improvements. Fig. 2 represents a front elevation of the same. Fig. 3 represents the rest for the shoe removed from the machine. Fig. 4 represents a reversed View of the same. Figs. 5 and 6 represent sections through the rest and illustrat-e the device in different positions. Fig. 7 represents a section on line 7 7 of Fig. 5. Fig. 8 represents a section on line 8 8 of Fig. 3. Fig. 9 shows the rest in inoperative position.

The machine shown is a part of the tacklasting machine commonly in use, and my improvements are shown as applied thereto. On the drawings, 10 indicates a horizontal sliding head or frame, upon which is sup-- the rest.

suitable fastening devices to the angular arm 15,V depending from the casting 16, the latter being'stationary at all'times. The support 14 is provided with forwardly-projecting ears or lugs 17 17, in which is journaled thetubular end'portion 18 of the rest 13. The said tubular end portion ,is provided .with a fiat face 19, against which two spring-pressed pins 2O 2O are adapted to press to hold the said rest in operative position, as indicated in Fig. 1, but which willpermitthe said rest to be swung down to inoperative position, as shown in Fig. 9. Said tubularrend portion is provided, further, with two `stops 21 21, which are adapted to engage the end of the support 14 and limit the forward and upward movement of the rest or abutment 13. The frontface ofthe rest is concave, as-at 22, being laterally extended, as shown, so as to afford a relatively large area against which the shoe may be'pressed or held. y

The hammer which I employ for laying the upper tightly against the last and the counter is indicated as a whole at 23. It is placed in a groove in the said rest, and its operative end lies Vnormally within the face 22 ofthe rest, as indicated in Fig. 7. The said end of the hammer is laterally enlarged and is adaptedto be drawn into the socket 24 inthe face 22 by a spring 25, having one end connected to a screw 26, attached to the hammer, and having its other end fastened to a screw-pin 27, secured to the rest or abutment. The screw 26 passes through a slot in the bottom ofsaid abutment, as indicated in Fig. 9. The said hammer is adapted to reciprocate longitudinally of thelast and to thisend is provided with an adjustable projection 28, having an inclined face 29 at its inner end. This projection is in line with a stop 30, secured to the under side of the tack-holder 12, so

that when the said tack-holderis reciprocated the projection 30 will 4engage the projection 28 and carry the-hammer forward withit, so as to cause it to extend beyond the face of Consequently each time the driver 11 is actuated and the tack-box is moved forward with the sliding frame10 the hammer will be caused to engage the upper and to lay it smoothly against the counter and hold it there while the tack is being driven home. The engaging eend of the projection 30 is inclined, so that when it strikes against the face 29 of the projection 28 the hammer is slightly raised, so that it has in addition to a longitudinal movement a lateral or upward movement to produce a wiping effect on the upper.

In order to limit the upward movement of the hammer,which may vary according to the inclination of the front of the rest, as will be explained, the said rest is provided with a forwardly-projecting finger 31, Whose end is adapted to engage a shoulder 32 on the top of the hammer, as shown in Figs. 5 and 6. The tubular end of the rest is grooved, as shown in Fig. 3 at 33, to provide for the movement of the projection 30. I may term the said projection 30 an actuator, sinceit operates or actuates the hammer at each reciprocation of the frame 10. The rest is formed in two parts jointed together on a horizontal axis, being provided with overlapping lugs connected by screw-pins 36 36, said lugs being indicated at 37 and 38, respectively, and the hammer is likewise formed in two parts connected together by a pintle 39. (See Figs. 5, 7, and 8.) Consequently the face of the rest may be held substantially vertically or at an inclination, as shown in Fig. 6, so that the position of the shoe may be varied according to different requirements. The axes of the pivot-pins 36 and the pintle 39 are in alinement when the hammer is withdrawn; but as the oscillatory movement of the loose ends of the hammer and rest is somewhat small and the longitudinal movement of the hammer itself is not very great relatively to the rest there is no danger of the rest and the hammer binding or being prevented from movement about their respective pivots. On the lower e'nd of the rest is formed a hook 40, with which the finger ofthe operative may be engaged to hold the shoe tightly against the rest or abutment. The rest, which performs the functions of a gage, is adjustable longitudinally, as ordinarily.

The stop 3l may be made thin enough to have a spring action, so as to yield when the hammer engagesy it and to return the said hammer when the pressure thereon is removed.

Having thus explained the nature of the invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it may be made or all of the modes of its use, I'declare that what I claim is 1. A machine of the character described having a hammer for engaging the upper and laying it against the counter during the operation of securing the upper to the insole, and

an abutment against Which the end of the shoe may be pressed during the operation of the hammer.

2. A machine of the character described, comprising fastening mechanism, a hammer having a non yielding flattened end, and means for giving said hammer a wiping stroke against the upper to cause the upper to lie snugly against the counter.

3. A machine of the character described, comprising fastening mechanism, a hammer, having a non-yielding flattened face to engage the upper at the heel end of the shoe,

and means for automatically reciprocating said hammer.

4. A machine of the character described, comprising fastening -mechanism, an abutment for the heel end of the last to rest against, and a hammer in said abutment.

5. A machine of the character described,

comprising fastening mechanism, an abut-` ment having a socketed face for the heel end of the last to rest against, and a hammer having a head located in the socket when in its inoperative position.

6. A machine of the character described, comprising fastening mechanism, an abutment for the heel end of the last, a hammer reciprocatory in a plane substantially at right angles to the said heel end of the last, and means for actuating said hammer.

7. A machine of the character described, comprising fastening mechanism, a hammer having a non-yielding flattened end and reciprocating in a plane substantially at right angles to the heel end of the last, and means for actuating said hammer to cause its end to move laterally toward the sole of the last to lay the upper flat against the counter.

8. A machine of the character described, comprising fastening mechanism, a hammer reciprocatory in a plane substantially at right angles to the heel end of the last, means for actuating said hammer,and provisions whereyby said hammer may be swung bodily to inoperative position.

9. A machine of the character described, comprising fastening mechanism, a hammer reciprocatory in a plane substantially at right angles to the heel end of the last, means for actuating said hammer,and provisions whereby the head of said hammer may be moved at an inclination to said plane.

In testimony whereof I have affixed my signature in presence of two witnesses.

MICHAEL F. KELLEY.
