HEEL-,-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 781,248, dated January 31, 1905. Application filed. June S, 1901. Serial No. 62,888.

' T0 on whom it may concern:

.Be it known that I, HAROLD A. WEBSTER, of Haverhill, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Heel-N ailing Machines, of which the following is a specifica- This invention has'relation wheeling-machines, and has for its object to provide a sim-f ple and durable contrivance by means of which a heel may be accurately and expeditiously secured to a shoe and the top lift spanked in place both at practically one operation. In.

carrying out this object it has been my endeavor to provide mechanism by means of which the nails may be driven in'parallelism into the heel rather than at an angle to each other.

Generally in heel-nailing machines the nails are placed loosely .in vertical apertures-in the templet, where they are able to incline more or less to the vertical, with the result that when they are forced into place by the driver their inclination is accentuated and they are unevenly spaced along the edge of the heel. In many cases the inclination of the nails relatively to each other causes them to'be bent or crippled.when an at-' tempt is made to drive .them into the heel, this requiring additional labor in removing the damaged heel, extracting the nails, and renailing the heel on the shoe. According to the present showing of the invention, however, the nails are placed in substantially horizontal apertures in a templet, which is arranged between the jack and the driver- ,head. The templet-holder, the driver-head,

and the jack are all in alinement in a horizontal plane and are so mounted and operated that the templet-holder is moved horizontally toward the driver-head by the jack. The heel is placed in a holder located between the templet and the jack, and it, too, is thrust into engagement with the templet by the jack, there;'-being normally a space between the jack and the templet for the reception of a top liftafter the heel is nailed to the shoe.

The mechanism by which the jack is moved or reci-procated consists of a camand slide,

the cam beingsoconstructed that the heel is nailed and the top lift spanked in place bysequently I may Vary said machine in many respects without departing from the spirit and scope of 'said invention. 7

Referring to the drawings, Figure 1 represents in side elevation my improved machine. Fig. 2 represents an end elevation of the same. Fig. 3 represents a section on line 3 3 of Fig. 1. Fig. 4 represents a section on line 4 4 of Fig. 1 and illustrates the heel-holder. Fig. 5 represents a section on line 5 5 of Fig. l and illustrates the templet for the nails, On the drawings, 10 indicates a table supported upon suitable side frames 11 13, connected by a tie-rod 12 and by a rear cross-bar 14. Upon the table are secured two standards 15 16, in the latter of which is journaled the shaft 17, to which power is transmitted from an initial driving-shaft 18, journaled in bearings on the table 10. The shaft 17 is equipped gear-'20 when the said pulley is moved longitudinally toward said gear by said bell-crank; but inasmuch as said clutches are common and any one of many different types may be used I have not shown one in detail. The bell-crank is actuated by a foot-lever 24;, fulcrumed at 25 on a rod or bar projecting across from one side frame to the other, the rearwardly-projecting end of said lever being connected to the bell-crank by a connecting-rod 26. A spring 27 tends to hold the front end of the foot-lever elevatedand thebelt-pulley in an unclutched position. By the depression of the said foot-lever the rotation of the beltpulley is imparted to theshaft 18 and, through the medium of the gears 19 and 20, to the shaft 17.

Removably secured to the standard 15 is a d river-head 28. This head has a shank 29,.projecting through the standard and threaded on its end to receive a nut 30, by which it is held in place. The head is secured on the inside of the standard and is provided with a plurality of drivers 3l,arranged in a row or otherwise, as desired. Extending between the standards 15 and 16 are two substantially horizontal guide rods or ways 32 33, upon which are slidingly supported the heel-holder, the templetholder,and the jack for the shoe. The said jack is indicated at 35 and is secured to the sliding carrier 34, operatively mounted upon the guides 32 33. The heel portion of the jack is in alinement with the driving-head and is adapted to be moved horizontally toward said head by a cam 36, having a groove 37 to receive a roller and pin, (indicated as a whole at 39,) projecting forward from the front of the carrier 34 and laterally with relation to rods or ways 32 33. Preferably the pin and roller are in the horizontal plane of the axis of shaft 17 and the median line of shank 29, so that the power is directly applied to the sliding carrier and the jack. The jack is so placed that the heel portion of the sole is in substantial parallelism with the face of the head 28.

The templet-holder is best shown in Fig. 5. It consists of a vertical plate 40, in sliding engagement with the guides 32 33 and having laterally-extended arms 41, with an intervening recess for the reception of the templet 42. The latter is provided with tongues 43 on its upper and lower ends to fit in grooves in the walls of the arms 41, as shown in Figs. 1 and 5, it being prevented from leaving said recess by a spring-bolt 44, mounted on the front of the holder. To further secure the templet removably in place in its holder, 1 provide a spring-latch 45, adapted to engage a notch in the face of the templet. A rest 46 for the top lift is adjustably secured to the templetholder, it being provided with a shoulder 47, by which said top lift may be properly positioned. The templet is located in alinement with the driver-head, so that when the templet-holder is moved toward said head the drivers will force the nails, which are placed in horizontal apertures 48 in said templet, out therefrom and into the heel. The horizontal arrangement of the nails holds them in parallelism even when the apertures in the templet are relatively large, and, as previously explained, they are therefore driven in parallelism into the heel at right angles to the face thereof without liability of being bent or improperly set. It will be readily understood that this arrangement of the parts whereby the nails rest horizontally in the templet and are driven in a horizontal direction, or substantially so, enables a templet to be employed with apertures of such a size that different sizes of nails may be employed. In other words, with a templet having apertures designed for the larger size of nail very much smaller nails may be employed without danger of their being driven in any other than absolutely parallel directions.

The heel-holder is best shown in Fig. 4, it being indicated at 49 and being shown as operatively supported upon the guides 32 It consists of a plate or bar having a forwardly-projecting arm 50, upon which the straight end of the heel is adapted to rest in alinement with the nail-holder.

To position the heel, I employ a gage 51, consisting of a lug on the head 52 of a spindle 53. The spindle and its head are placed in an aperture in the arm and project beyond the end of the latter. The end of the spindle is threaded to receive an adj usting-nut 54, by which the gage 51 may be adjusted in position. A spring 55 surrounds the spindle and bears against the arm and the head to force the gage rearwardly when the nut is rotated in the direction to permit it. The heel is preferably not held in place save by the hand of the operative, and it is located between the jack and the templet, as shown in Fig. 1. This is permitted by the substantially horizontal surface of the heel-holder, whereby the straight end or breast of the heel will rest upon such surface without tipping oil". In fact, under some circumstances the heel will rest and remain in proper position without being held there by the hand of the operative. Between the templet and the standard 15 are placed springs 56 56, which encircle the guiderods32 33, there being similar springs 57 57 placed between the templet-holder and the heel-holder. These springs restore the holders 40 and 49 to position when the jack is withdrawn. To limit their retrograde movement, collars 58 58 are adjustably secured upon the said guide-rods 32 The operation of the machine is as follows: The templet is loaded with nails and secured in its holder, a shoe is placed upon the jack, and the operative rests a heel in proper position upon the holder. The foot-treadlc is then depressed, with the result that the jack is thrust positively toward the driver-head. As it moves to the left in Fig. 1 the sole of the shoe first engages the holder 49, the latter being moved by the jack until it comes in contact with the holder for the templet, after which both holders move in unison with the jack toward the standard 15 and the driverhead. The drivers enter the apertures in the templet and force the nails through the heel into the sole of the shoe, the movement being stopped in time to leave the ends of the nails projecting from the heel. This requires one half-revolution of the cam. During the remainder of the revolution the jack is withdrawn a short distance and is then forced outlift.

ward for thepurpose of spanking on the top To accomplish this, it will be observed that the cam-groove has a jog inward toward the shaft 17 When the shaft has completed one-half of its revolution and the jack moves in a retrograde direction, the springs 56 57 force the two holders 40 49 toward their'original positions, leaving an aperture between said holders for the insertion of the top lift to proper position upon the rest 46, after which the forward movement of v the jack causes the said top lift to be forced upon the partially-projecting nails, or, asit is termed, to be spanked in place.

It will be observed that the springs 56 are much strongerthan those at 57 in order that I the outward movement of the jack will cause the compression of the springs 57 before the compression of the springs 56, whereby the heel may be brought against the templet before the drivers force the nails outward therefrom. i

The jack, as previously explained, is arranged with its median line ina substantially vertical position, with the heel portion uppermost, and the other complemental heel-attaoh-' I ing elements are correspondingly arranged, so

that the operator is able to view the work during the progress of the nailing operation.

The parts are open or exposed, so that there is little or no danger of the operators fingers being crushed vor injured in placing a heel upon its holder or steadying it when the jack is moving toward the driver-head.

It is evident that when I refer to the apertures in the templet and the movement of the jack as substantially horizontal I mean by that termto include any arrangement of the apertures or movement of the jack whereby the nails will lie or rest in their aperturesin parallelism so as to be driven properly into the heel.

So far as I am aware I am the first to have provided a heel-nailing machine with a templetin which the nails remain by gravity with- 7 with horizontally-extended lateral guide-arms adapted to receive the templet, and means for locking the templet in position, said templetholder being located between said jack and head and, adapted to be moved toward th latter by the jack. 2.
