fiPECIPICATION forming part of Letters Patent P10309526, dated December 23, 1884.

Application liled August 30, 1884.

To ctZZ whom it may concern.-

Be it known that 1, Louis Corn, of the city of St. Hyacinthe, in the county of St. Hyacinthe, Province of Quebec, Dominion of Canada, have invented new and useful Improvements in Heel-Nailing Machines; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention has reference to improvements in a machine for nailing the heels and soles of boots and shoes, to enable the same to work with greater rapidity, while the opera tor is enabled to adjust the position of the heel upon the sole with greater exactness than when operating with the machine as constructed before this my present invention.

By my improvements an operator can, with less bodily labor and in the same time required by the old machine to nail on two heels, with myimproved machine nail on five heels, thus making a large saving in the price of the labor to be paid for this operation, and, in large establishments, the cost and room required for two (and a half, if I may so call it) machines to do the work of one of my improved machines.

The features which form my invention will be hereinafter fully set forth and described.

In the drawings hereunto annexed similar letters of reference indicate like parts.

Figure 1 is a front elevation of a boot and shoe heel nailing machine in which are embodied the improvements forming my pres ent invention. Fig. 2 is a side elevation of the machine shown in Fig. 1. Fig. 3 is a plan of the treadle for operating rapidly the working parts actuatingthc presser-plate or follower-block a of the machine. Fig. 4-. is a front elevation showing the manner of attaching the lower end of connecting-rods to the treadle. Fig. 5 is a sectional side elevational View of the parts shown in Fig. i, the section beingtaken at line ac, Fig. 4-. The nut and end of stud-are, however, removed. Fig. 6 is a diagram showing the manner in which a boot or shoe is held by the machine shown in Figs. 1 and 2 while the nailing of the heel to the sole is accomplished. Fig. 7 is a first modification of equivalent parts. Fig. 8 is a second modification of equivalent parts. Fig. 9 is a side elevation of jacking lever and (No model.)

wheel. Fig. 10 is a detail showing the manner of guiding the connecting-rods.

As in the machine shown in the drawings a considerable portion of it is old, it becomes necessary for the clear understanding in what my invention consists to enter at some length into a particular description of the parts that are old as well as those that are new, also into a general description of how the machine has been heretofore operated.

Letter A is a lower frame, which. is firmly attached 011 the floor, &c., in the ordinary manner. To this is attached the upper frame, B. On the frame B is secured by bolts and nuts 0 a standard, D, within which a plunger, E, and rod F are situated, as shown in Fig. 6. The standard is provided with a head, G, having within it vertical or nearly vertical holes H, situated in the positions in which the nails are required to pass through the sole I into the heel K. fork projections L, one for each of the holes II, in which they freely slide, so that when the plunger and projections L are moved downward (from the position they are shown in in Fig. 6) a sufficient amount the nails M may be placed in the holes H. As shown in Fig. 6, the plungerE is in a midway position, showing a nail, M, in a partly-driven condition, or as if the plunger had risen from about the level of the line a, and when the plunger has risen to within a short distance of touching the head G- the nails will have been completely driven home into the sole and heel.

c is a presser-plate or followenblockm'hich is brought down with considerable force upon the heel K and tightly holds the sole and heel upon the head G while the nails are being driven. Fig. 6 so clearly shows 110w the sole and heel are held that no further explanation is required in this respect.

The rod F extends below the standard D, as shown in Fig. l, and is operated by the following mechanism: To the under side of the frame B are attached two brackets, b, in which is journaled arevolving shaft, 0, provided with a disk, d, at its front end. From this disk projects a crank-pin, c, which operates a pitman, f. The end of the pitman does not come in contact with the end of the rod F; but whenever it is desired to operate the rod F a The plunger E is provided with.

sliding block is interposed between the end of the rod Fand the end of the pitman f, the said block being of such thickness that the desired portion of the stroke of the pitman will be im- 5' parted to the rod F. This said sliding block is operated by the handle 8.

On the shaft 0 is secured a gear-wheel, g, which intermeshes with a pinion, h, secured on the driving-shaft 1', carried, journaled, and

10 revolving in lugs is, formed on the frame A.

Z is a fiy-wheel secured on the shaft i, and represents ordinary pulleys for the transmission of power by a belt in the ordinary way to revolve the shaft i.

n is a guide which is attached to the presserplate or follower-block a to adjust the position of the heel K upon the sole I, as shown in Fig. 6; but with persons who have become expert in the use of the machine this guide it is not required.

Now, all that has been hereinabove described is old, or substantially old, and the above description is given for the purpose of conveying a clear knowledge of the state of the machine at the time of my invention, and to complete the-description of what is old I have only to state, in addition, that the presserplate or follower-block a was heretofore operated or brought down upon the heel K and raised therefrom by a screw situated above and operated in an ordinary manner. This required the use of the hands of the operator to lower and raise the presser-plate or follower-block a at each operation of nailing on a heel, and occupied much time and required much labor. The object of my invention is to provide the machine with a means of rapidly operating the follower-block a, and, further, that such means may be automatic in so far as the raising of the follower-block is concerned after the operation of nailing the sole and heel together has been accomplished.

a is a socket or guide, in which moves a slide-bar, b,provided with any suitable feather or key for keeping the slide-bar from twisting around, while it is free to slide up and down within the socket or guide a.

On the lower end of the slide-bar a cross- -head, 0, is formed or attached, and, as shown in Fig. 1, to the lower side of this cross-head the follower-block or presser-plate a is secured by a dovetail recess in the cross-head and corresponding dovetail projection on the followerblock or presser-plate.

On the two extremities of the cross-head c are formed ordinary journals to receive upon them the connecting-rods (1. These are secured in the ordinary way by nuts e, so .arranged that while they hold the connecting- 60 rods upon the journals they do not bind or tighten the rods in any way. The said connecting rods d pass down through suitable openings formed in the base of the part of the frame-work B, and extend down a sufficient 65 distance to connect with a treadle situated in the lower part of the frame A. This treadle and the manner of connecting the connectingrods 'd thereto will be hereinafter described.

The connecting-rods are provided with rackteeth 8, at the position shown in Fig. 2, for the purpose of employing an auxiliary leverage of greater force than that given by the treadle, which treadle is provided for the purposes, (with others,) first, of givingrapid motion to the cross-head, and, second, that such motion may be given by the foot of the operator, leaving his hands free to hold the sole and heel in proper adjustment of position, while the 'presser-plate or follower-block a descends upon them, both of which effect a very valuable saving of time.

In the lower part of the frame A is secured a pivot-shaft, f, which forms the pivot upon which the treadle vibrates. The treadle consists of a sleeve, arms h, and foot plate 1'. The arms h are of such length that the foot-plate extends outside of the frame A and to the front thereof, as shown in Fig. 2. The arms h are further configurated, as shown in Fig. 3, to extend out an equal distance with the distance between the connecting-rods (1. These rods eachterminate in an eye, k, having a stud projection, l, passing through slotted openings m in the arms 7/, and are secured by the nuts n.

On the sleeve 9 is formed a third arm, 0, upon which a counterbalanceweight, 1), placed and secured.

The auxiliary leverage hereinbefore men:

tioned is constructed and arranged as follows: In the side bars,a ,of the frame A is journaled a shaft, b", on which are secured two pinions, 0 one of each of which engages with the rackteeth 8 of the two connecting-rods d, and on the end of the shaft 1) projecting beyond the frame A is secured a wheel, (1 and lever 0".

The said wheel is provided with ,rack-teeth,

extending around such part of its periphery as is required. f is a pawl, pivoted upon a stud, g, projecting from the frame A, to hold the said wheel d and lever 6 down after the lever has been pressed down by the hand of the operator after the follower-block a has been brought down upon the heel K by the treadle.

h is an elastic washer or collar, (see Figs. 1 and 2,) placed upon the slide-bar b and rest ing upon the cross-head c2 11 are guides (see Figs. 2 and 10) projecting from the frame A, and supporting and guiding the connecting-rods d, there being one of these guides to each said connecting-rod.

I will now describe the operation of the mechanism above described, and afterward refer to certain modifications of the auxiliary leverage in relation thereto.

The pawl f is disengaged from the wheel d whereupon the preponderance of weight of the counter-balance 1) causes the treadle i, connecting-rods d, cross-head c, presser-plate or follower-block a, and slide-bar b to rise automatically until the elastic washer h is gripped between the socket a and cross-head c. The object of the washer is to prevent the jar to the parts of the machine which would arise by the cross-head coming in contact with the socket a when the machine is working rapidly. The head G is supplied with the nails that are intended to nail a sole and heel together. The boot or shoe is then placed upon the standard and head D G in the position shown in Fig. 6, and the heel K properly adjusted in position. The foot of the operator is now placed on the treadle'plate t and sufficient weight applied to it to overcome the preponderance of the weight of the counterbalance 1), also the friction of the parts, and bring the presser-plate or follower-block a rapidly down upon the heel K, in doing which the downward movement of the connecting-rods d causes their rack-teeth S to revolve the pinions 0", shaft b, wheel (F, and vibrate the lever 6 bringing it to about the horizontal position as shown in Figs. 1 and 2, the pawl f holding the lever, by means of the rack-teeth on the wheel (F, to the position it is thus brought to by the treadle. The operator new places one of his hands upon the lever 0 and jacks or forcibly compresses the sole and heel between the said parts holding them. The shaft 2 having been previously put in motion, the sliding block hereinabove mentioned is then operated by the handle 8, causing the pitman to operate the rod F and drive the nails M (see Figs. 1, 2, and 6) home, fastening the sole and heel together. The pawl 3 5 f is again raised, and by the united effects of the elasticity of the heel and sole and counterbalance 1) the motion of the parts to raise the followerblock or presser-plate a springs into rapid action, for although the elasticity of the heel and sole only acts throughout a small distance or portion of the motion, yet they act through a sufficient distance to start the parts into rapid motion, and as the wheel (1", from its position and arrangement, acts as a flywheel, and the action of the counterbalance p is a continuous one, the rapid motion is continued until stopped by the elastic cushion 7L2.

lVith regard to the modif cation of the auxiliary leverage, I wish to remark that although the wheel (l is not without considerable use, yet it may be dispensed with or suitable equivalents therefor substitutedas, for example, the lever alone maybe used attached on the extension of the shaft b and any ordinary stationary means or catch may be provided for holding it in any required position; or on the lever may be attached a segment provided with rack-teeth for the pawl f to engage with.

Again, as a first modification or equivalent of the rack-teeth s on the connecting-rods d and pinions c" on the shaft 1), the shaft 1) may have crankarms a" secured upon it, and on the connecting-rods d may be attached adjustable slides b provided with eyes 0, the cranks a and eyes e being connected together by links d and pins, in the ordinary manner, so that by the vibrations of the crank 1n the are c the rods d may be moved. up and down, as indicated by the lines f and g, the amount of travel of the rods (1' up and down being governed in a measure by the amount of vibration of the cranks, the whole as indicated in Fig. 7.

As a yet further or second modification of that last above described, the cranks a may be so situated with regard to the required motion of the connecting-rods d that the cranks a and links (1 will form a toggle-j oint, as illus trated in Fig. 8.

That I claim, and wish to secure by Letters Patent, is as follows:

1. The combination, in asole and heel nailing machine, of the standard and head D G, constructed as described, with a followerblock, a, operated by a treadle and auxiliary leverage, substantially as described,- with said treadle and auxiliary leverage, the whole substantially as set forth.

2. The combination, in a sole and heel nailing machine, of the standard and head D G, constructed and arranged as described, with a follower-block, a, operated by a treadle and auxiliary leverage, substantially as descrlbed, with said treadle and auxiliary leverage, and counter-balance p, the whole substantially as described and set forth.

3. The combination of the standard and head D G, follower-block a, cross-head c, conneeting-rods d, treadle i, counter-balance p, lever a, shaft b and pinion a, all construct ed, arranged, and operating substantially in the manner and for the purposes set forth and as shown.

4. The combination of the standard D, pro vided with plunger E, having projections L, head G, having nail-receiving holes H, said holes H also receiving and guiding said projections L, as shown and described, followerblock a, cross-head c, connecting-rod d, treadle i, and counter-balance p, the whole constructed and arranged substantially as described.

5. The combination of the standard D, provided with plunger E, having projections L, head G, having nail-receiving holes H. said holes H also receiving and guiding said projections L, as shown and described, follower-block a, cross-head c, connecting-rods d, and treadle t, the whole constructed, arranged, and operated substantially as de scribed and shown.
