HEEL-NAlLlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 280,399, dated July 3, 1883.

Application filed February 13,1883. (No modeLY To all whom it may concern.-

2 is a plan view thereof. Fig. 3 is a side elevation, and Fig. 4 is a detail view, hereinafter referred to.

This invention is an improvement upon that described in Letters PatentNo. 252,215, dated January 10, 1882, and No. 259,687, dated June 20,1882, granted Henry A. Henderson, assignor; and it consists in a heel-nailing machine having the templet and nail-holder, or either, provided with automatic movements, as and for the purposes hereinafter specified. In said patented machine the templet and nailholder are moved at proper intervals by the attendant or boy who assists in operating the The templet must be moved into position beneath the awls, when the heel-blank is to be punctured, immediately after the work has been placed in position, and before the awls are reciprocated, and after the heel has been punctured and the awls withdrawn the nailcarrier must be pushed forward upon the templet-plate to a position over the templet,when the drivers are caused to reciprocate to drive the nails fed by the nail holder and carrier through the templet into the heel-blank; or, if drivers alone are used, the nail holder and carrier must be pushed forward by hand immediately before the drivers are reciprocated, and before the machine can be again operated it is necessary that the templet and nail holder and carrier be drawn back to their original position. If, after the nails are driven, the heel-spanker is caused to be reciprocated, it is necessary, of course, to remove the templet and nail-holder, or the nail-holder before it can be brought into operation; and if by accident the nail-holder and templet shall not loe withdrawn when specified and the awlsor spanker brought into position and reciprocated some damage would be done the machine. I have therefore conceived it desirable to provide the nail-holder and templet with automatic movements, whereby they may be fed forward and withdrawn at stated intervals without requiring .the care or attention of the operator or his assistant. This construction is an advantage in another respect, in that it gives the assistant more time to help the operator. In order that the operator may have full control of the movement of these parts, I prefer to so arrange the operative mechanism, when awls and a spanker are used in addition to drivers, that the movement of one to take the place of the other shall also bring into position the mechanism for operating the templet or nail-holder, as the case may be.

Referring to the drawings, A represents the cross-head of the machine. It is reciprooated by mechanism like or substantially like that described in said Letters Patent, or in any other desirable way, and it supports or carries the revolving head a, which may have an arm, a, for supporting the awls a, an arm, (E, for supporting the drivers a, an arm, (6*, supporting the spanker a.

Upon the shaft a supporting the revolving head at its rear end, I have attached the gearwheel a", which operates the gear-wheel to", also secured to the cross-head directly, or by means of an intermediate gear. This gear-wheel a carries upon its face the projections a which extend outwardly therefrom, and are adapted by the movement of the gear-wheel a to be brought into position successively over the slide-bars B B. Each of these slide-bars is supported by the bracket 1), bolted to the leftside frame of the machine, or otherwise suitably supported, and each is held up or supported and returned to normal position by the coiled spring b. The lower ends, I)", of these bars B B are inclined or wedge-shaped, as rep resented, and the downward movement there of actuates or moves horizontally the connecting-bars b I), with the ends of which they contact. The connectingbar I) is pivoted at its outer end to the lever D which is pivoted at b to a bracket 1), and the other end, I), of this lever bears against the end of the templet-plate. The horizontal bar I) is connected with and operates the lever If", which is also pivoted to to bring the other of the projections (0 overthe standard b and bears upon or is attached to the rear end of the nail-holder plate B is readily seen that upon the downward movement of the cross-head the inclines upon the slide-bars B B move the connecting rods or bars 6 I), and cause them to move the levers b I), and therefore move the templet and nailholder plates.

As the machine is generally operated it is necessary that thetemplet-plate shall be moved into position first, and when the machine is thus operated one of the projections a upon the gear or disk (5 must be brought into position over the slide-bar B upon the moving of the awls into position. movement of the crosshead the templet is moved into position, and the movement of the templet must be sufliciently rapid to bring it into position before the awls, in their downward movement, shall reach it. The templet having been moved into position, the awlblock moves it downward vertically,and consequently there must be a downwardly-extending portion b upon the end of the templet-plate, in order that the end of the lever b shall bear against some portion of the plate while it is being moved downward. As the cross -head then lifts, releasing the lever b by moving its operative slide, out of connec-- tion with the bar b and as a spring, 0, is used for returning the templet-plate to its original position, as hereinafter explained, it is necessary to lock the templet-plate after it has been automatically pushed into position by the lever b and this is effected by means of the catch D, .(see,Fig. 4,) which is attached at d, in the recess cl, to the table d", and automatically shuts behind the templet by spring-pressure, and the projection (2 upon the nail-holder, when the nail-holder is moved into position, throws down this catch and holds itdown, releasing the templet-plate and permitting the spring C to return the templet to its normal position on the upward movement of the crosshead. The awls having been driven and withdrawn and the templet locked in position, the drivers are next moved into place. This causes the disk or gear a to be revolved sufficiently the sliding bar B, and the downward movement of the cross-head causes the nail-carrier to be moved automatically into .proper position to discharge its nails into the templet and to receive the drivers. It is held in this position during the descent of the drivers by means of the sliding bar- B, which acts as a stop or catch in holding the connecting-bar b stationary at the end of its outward movement; but upon the upward movement of the crosshead, the bar I) being .free, the lever If" is released, and the nail-holder having unlocked the templet, the springs C C draw both the templet and nail-holder back to their original position, and in so doing cause the connectingrods 1) b to be returned to their normal position. The length of the incline upon the slidebars B B must be such that the templet and Upon the downward nail-holder be moved into position before the awls or drivers shall descend far enough to prevent such a movement.

- movement of the ends of the levers will be varied, according to direction of the movement of the pin.

In case awls should not be used the nailholder only will be used, and in that event it will be operated as the nail-holder herein described is operated.

Of course there are many mechanical equivalents for the mechanism herein described for giving the templet and nail-holder, or either of them, the automatic movements herein specified, and I do not intend to confine myself to the specific construction herein described, but propose to use as a substitute therefor any other suitable mechanism for providing these automatic movements to the templet and nailholder, or either, from a portion of the machine which is actuated by power.

It is not necessary that the templet and nail holder, or either of them, be located in relalation to the jack and drivers, as represented, for they may be upon one side or the other of the machine, if desired.

It will be observed that the downward move-' ment of the awl and drivers causes the templet and nail-holder to be brought into operative position, and that the reverse movements of the drivers cause the reverse movement or withdrawal of the templet and nail-holder, and that, therefore, the templet and nail-holder cannot by accident be left projecting or partly projecting from their supports when not in use.

The jack or support for the work (not shown) preferably has a horizontal movement upon the table or bed 6, as described in said patent, and any suitable heel-blank and shoe-centering devices may be employed. In lieu of the revolving head, the sliding head of said Pat ent No. 252,215 can be used, in which case the projections a instead of being upon a revolving disk, are upon the side of the sliding head.

In'case it shall be desirable to give the sliding bars B B more throw than they now have,

in order that the inclines or cam-surfaces b maybe longer and more gradual, a lever for each bar can be arranged between the crosshead and the end of the bar, with its fulcrum nearer to the cross-head. If this construction is employed, of course the slide-bars will be moved from the cross-head sufliciently to allow the use of levers, and of course by the use the movement communicated to them by the cross-head is increased, so that the slide-bars B B and their camsor inclines may have any given extent of movement.

I may use the retracting-springs O C, or either of them, without the remainder of the automatic mechanism, if I desire; and for the purposes of this invention it is of course immaterial whether a templet -plate or nailtive position.

holder, or either of them, is actuatedupon a straight line, or whether they are revolved upon a center, as described in my Letters Patent No. 271,117, or otherwise moved into operative position.

I may use forpresenting the work to the heel-nailing'mechanisnreither the jack described in the above-named patents or any other suitable one.

I am aware that the patent to McKay and Fairfield of July 21, 1874, No- 153,360, and that to Fisher, dated December 13, 1881, N0. 250, 654, describe a class of machines which may properly be called heel-forming or heelpreparing machines, in that they form or make the'heel-blank from a number of heel-lifts by compression, and prepare the heel-blank for attachment to the sole of a boot or shoe by perforating it and filling the perforations with nails partly driven into them. This class of machines is used as an auxiliary to the heelattaching machinethat is, the machine that fastens the heel-blank to the soles of a boot or shoe; and the principal heel-attaching ma chine which employs such auxiliary heel forming and loading machine is that made by Me- Kay & Bigelow Heel -Nailing Machine Association, and is known as the McKay & Bi gelow heel-nailing machine. My invention does not belong to this class of machines. It does not employ a separate or auxiliary heelforming mechanism. The unperforated heelblank is compressed directly upon the outsole of the boot or shoe, and is nailed directly thereto without any preparatory loading by an other machine. described in the patents above referred to. The machines made under said patents have a templet and a heel-holder which are adaptedto be moved by hand into and out of opera-- While this method of opera tion answers very well, yet it is not altogether free from objection, in that the operator or his assistant may not move eitherthe awls, drivers, or heel-spanker, or the templet or nail-holder at the proper time, and if this is not done an accident or breakage of the machine upon the next reciprocation of the cross head may occur. In order to avoid this liability to accident, as well as to increase the speed of the machine and lighten the work of the assistant, I have devised a machine which is in many respects like that described in said patent, but which has, in lieu of the hand-moved templet and nail-holder, an automaticallymoved templet and nail-holder.

It will be observed that the retracting springs O C serve two purposes: first, they act to withdraw the templet-plate and the nail-holder plate to their inoperative positions upon the withdrawal of the stops which hold them in their operative position-that is, in a position to co-operate with the awls and drivers; second, they act as a safety device in withdrawing the plates to that inoperative position when they are not automatically moved into operative position, in case the operator or This class of machine is well.

his assistant should not have moved them sufficiently far to engage with the stops, or to come into operative position with the awls and drivers.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United Statcs 1.
