HEEL-ATTACHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 627,741, dated June 27, 1899.

Application filed January 21, 1899. Serial No. 702,943. (No model.)

My invention relates to a machine for at taching heels loaded with nails to the heelseats of the soles of boots and shoes, and is especially adapted to be used with such heels 7 as are constructed by the operation of the nailing-machines shown in reissued United States Letters Patent No. 11,486, dated April 16, 1895, although itis equally well adapted for all heels in which the attaching-nails are driven before the heel is attached to the sole of the boot or shoe.

My invention consists of certain novel features hereinafter described, and particularly pointed out in the claims.

My invention is shown applied to a heelmachine in which there is a vertically-reciproeating head carrying an arm adapted to be oscillated by a shaft, one end of said arm carrying the nail-driving mechanism for attaching heels and the other end of said arm carrying the top lift to be attached to the heel at the proper time. I have not shown the mechanism for reciprocating the cross-head, as it is too wellknown in the art to require a description.

In the accompanying drawings, which illustrate a construction embodying my invention, Figure 1 represents a Vertical section of such cross-head as is referred to with the jack in position for holding the shoe to be heeled. Fig. 2 is a top plan view of the nail-' sectional view through the n ail-driving block, taken on the line 6 6, Fig.2. Figs.7and 8 are respectively side and central sectional views of one of the sleeves, showinga spring engaging a nail to hold the heel in position on the naildriving block; Fig. 9 is a sectional View on the line X X, Fig. 8. Fig. 10 is a cross-sectional View through the nail-driving-block on the line 10 10, Fig. 2.

Like letters of reference refer to like parts throughout the several views.

In the drawings, A represents the crosshead, (shown in section in Fig. 1,) and B rods by which it is reciprocated.

B is a last supported on a suitable jack and on which is placed the shoe B for heeling.

The arm C carries at one end the usual spring-clamps for holding the top lift. This arm 0 is mounted on a suitable shaft C and may be located in any desired Way, either in the position in which it is shown or the reverse position, with the driving mechanism in a position to receive the loaded heel F. D is a nail-driving block adapted to be attached to one end of the arm 0 by clamps D D fitting in the recesses D of the drivingblock. The clamp D is cast with the arm C, and the clamp D is movable to release the driving-block D, which can be fixed fast in its adjusted position by means of the set-screw D The pin D moves in a slot in the arm C, and its object is to hold the clamp D in its vertical position. By loosening up the set-screw D the nail-driving block may be moved along the inward extensions D D of the clamps D and D to any desired position and then secured by tightening up the set-screw D These two clamps form a longitudinal guideway in which the nail-driving block may be adjusted. This driving-block is provided with a series of large drivers E, secured in the block, and also three small drivers E. The ends F of the large drivers are beveled, this construction'enabling the nails to enterthe drivers readily. The three small drivers E pass down into the hollow sleeves G, extending beyond the face of the block and provided near their lower ends with a circular shoulder G, resting against the bottom side of the block D. The spring G is located around said sleeve and bears at its lower end against the collar G and at its upper end against the upper limit of the recess G in whichare located the driver E and the spring G On one side of the sleeve G, as shown in Figs. 7 and 8, is a spring H,which is curved inwardly at its lower end and projects far enough into the sleeve G to hold a nail when pressed inwardly beyond the curved portion H, so that the heel cannot be pulled off the block until the act of driving the nail into the shoe to attach the heel takes place, which causes the sleeve G (of which there are three) to recede up into the block, as shown in Figs. 10 and 5, and thereby unlock the spring from the nail and release the heel. The spring G also holds the smaller spring H in its inward position, as shown in Fig. 8, to engage and lock the nails upon placing the loaded heel upon the nail-driving block. The ends H of the sleeves are also made beveled, so that the sleeves can be readily loaded with nails on the loaded heel.

In practice where a machine such as is shownin Fig. 1 is used the loaded heel is placed upon the nail-driving block (which is then uppermost) to receive the heel from the boy attendant, so that the heads of four of the nails are received by the ends of the large drivers E, and the heads of three of the nails are received into the lower ends of the sleeves G and pass up by the springs H in the sleeves G, and thereby hold the heel to the driving-block by means of the nails in the heel passing above the curved portion H of the spring H. The arm 0 is then turned by the boy to bring the loaded heel over the heelseat F of the boot or shoe, (see Fig. 1,) and the cross-head is then reciprocated, driving the nails and securing the heel to the sole of the boot or shoe, as shown in Fig. 5. Then the arm 0 is oscillated and the top lift is brought in line with the heel on the shoe and attached to the heel by the next reciprocation of the head A. After the operator has removed the shoe, with the heel and top lift attached, from the jack and is placing another shoe on the jack to receive a heel and top lift the boy attendant places a loaded heel on the driving-block, as described, and then reverses the nail driving block and places a top lift upon the top-lift block. Then the machine is ready for the operator, first, to secure the heel upon the shoe, then reverse the arm 0, and secure the top lift to the heel. During this operation of putting the heel and top lift onto the shoe the boy with one hand is securing a loaded heel and with the other hand a top lift.

The nail-block and the top-lift block, which are carried on opposite ends of the arm 0, are not turned in a complete circle in the operation of the Woodward heel-attachin g machine,

- as it is found in practice more advantageous to turn the nail-driving block D both downwardly and upwardly in the same semicircle on one side of the machine and the top-lift block downwardly and upwardly in the same semicircle on the opposite side of the machine, so that the arm 0 is an oscillating arm and not a rotatable or a revoluble arm.

The adj ustability of the nail-block, as previously described, is for the purpose of locating the heel on the heel-seat without adj usting the jack, which is necessary for diiferent shapes of heels, as some heels are straight on the back, while others are curved inwardly toward the center of the foot, and therefore I have provided mechanism for adjusting the block without adjusting the jack, so that the upper rear edge of the heel will always come directly over the rear edge of the shoe. For instance, in driving what is known as a common-sense heel, which is straight on the back, the nails are along the edge and the drivingblock may be located so that the rear edge of the heel will be in line directly with the rear edge of the shoe in the attachment of the heel, while in a French heel the nails are arranged around the edge of the bottom of the heel, but the upper side of the heel, which comes in contact with the heel-seat, would project over the bottom part of the heel-seat. Therefore it becomes necessary to adjust the driving-block forwardly, so that the rear edge of the top .side of the heel will come directly over the rear edge of the shoe. In other words, the adjustability of the block provides that whatever the shape of the heel may be the rear edge of the top of the heel will always be in line with the rear edge of the heel-seat of the boot or shoe.

In driving the heel upon the shoe it is necessary that the jack should be held firmly while the operation is taking place, because if when the shoe strikes the heel-seat it is not locked firmly the shoe will slide out forward, and thereby bend the nails and not drive them. It is therefore necessary in order to keep the jack in place that the jack should be locked in some definite position and not be adjustable a little backward or a little forward. Itmust be absolutely in the same place during the driving operation.

-When the jack is worked in one position, there will come a little wear in that particular part under the jack, so that when the jack is moved forward and backward for the attachment of different sizes of heels there will not be the same bearing for-the jack, which is liable to slip out from under the shoe, whereas in the present machine, the jack being'always fixed and not adjustable, any wear which may come under the jack has no effect on the permanency of the jack, the only effect beingto keep the jack more firmlylocated in its fixed position. The top-lift spankerblock, as previously mentioned, is adjustable, as is usual in heeling-machines, the object being to. locate the top lift according to the shape of the heel, as the top lift in a French heel comes nearer the center of the shoe than acommon-sense heel. Althoughlhaveshown three sleeves G, yet it will be understood that any desired number may be used.

By having three sleeves projecting above the ends of the other drivers the attendant can readily determine where to place the heel so that the two breast-nails and the rear nail will come in their proper places. Conse- IlO quently by locating these nails properly the other nails come into the concave recesses of their proper drivers. Where all the holes for the nails are on a level, as in the nailblock shown and described in the prior art, the attendant is liable to place the breastnails in the wrong holes. Consequently all the other nails will be located out of place and time is lost' in properly locating the heel. These three sleeves serve as guides to indicate the position of ,certain nails, and the other nails naturally come into their proper positions. These sleeves also serve to equalize the pressure on the heel, as they are independent of one another, and not being connected they form a series of independent concave circular pressure-feet. It is found in practice that the heel-seat is not always even and also many of the heels are not of the same thickness from side to side and from end to end. Consequently if a solid yielding so that the heads of the nails not being held in the recesses of the drivers at the beginning of the driving operation are moved to one side of the holes in the nail-block out of perfect alinement with the drivers, and in the driving operation the nails are apt to be tipped over by the drivers, thereby throwing the heel off to one side of the shoe with the upper portion of the nails turned flat on the top of the heel, whereas by the use of three independent sleeves if one of said sleeves strikes first the uneven surface that one only yields without afiecting the heel, as the pressure is on a small surface and in the line of drivers and the other sleeves come to their proper places in contact with the heel and-hold it in proper position during the driving operation.

1 By having the heads of the nails located in the recesses of the drivers before the sleeves come in contact with the heel the tipping of the nails is prevented, because the heads of the nails are always in contact with the drivers and in the line of driving, and therefore cannot slip out of proper alinement during the driving operation. Further, such tipping cannot take place, because the pressure on the sleeves is in the line of the driving and does not come in advance of the nail-driving operation, but on or about the same, time, and the driving-block does not touch the outer edge of the heel, which is apt to be uneven in the manufactured heel, in time to allow it to slip, because the nails are through the heelseat and being turned before the block comes flat on the top of the heel.

When heels areloaded with nails, the nails in the heel do not always stand perfectly straight, and consequently in applying the loaded heel to the nail-block it becomes necessary to provide means to straighten up the nails, and the beveled ends of the drivers and sleeves cause the nails to straighten up, thus centering them in their driving position, so that in the driving operation the nails are driven straight through the heel into the shoe and attach the heel to the shoe.

I do not limit myself to the arrangement and construction shown, as the same may be varied without departing from the spirit of my invention.
