"explaining its nature.

T he invention relates to a heel-attaching machine of the organization hereinafter specified.

Referring to the drawings :-Figure 1 is a view in front elevation of a machine having the features of my invention; Fig. 2 is a view in side elevation thereof; Fig. 3 is a view in vertical section upon the dotted line of Fig. 1; Fig. t is a view in plan, and Fig.

5 in section, of the toplift holder; Fig. 6 is a view in elevation of the upper part of the machine showing the jacks and rotary heads facing the same way; Fig. 7 is a view in section upon, and in plan below, the dotted line of Fig. 6; Fig. 8 is an elevation of the upper portion of the machine showing it as provided with asingle rotary head and jack; Fig. 9 is a view of a heel-blank with protruding attaching nails; Fig. 10 is a view showing the heel-blank held by its protruding nails to the templet or heel carrier; and Fig. 11 is an enlarged view of the toplift carrier and spanker shown in Figs. 4 and A is the frame of the machine. It com prises the two uprights a a, the cross table a preferably integral with the uprights, and it has the two fronts (a a.

B is a shaft which is mounted in slide boxes Z) 6, which slide in the guides b 6 I'GSPGCtlWBlY attached to or formed upon the upper end of the sides a1 a of the frame. The shaft extends through these boxes and is encircled by the connecting rods 0 C which connect the shaft with the cranks c 0' respectively of the crank shaft 0 At one end of the shaft B is a disk 6 which carries cam rolls 6 (see Figs. 1 and 2), and these cam rolls are arranged to alternately travel along the cam grooves in the stationary cam plate Z). The cam plate has the switches and in all respects is like the cam plate illustrated and described in my United States Patents No. 694,665, dated March at, 1902, and No. 570,648, dated November 3, 1896, and need not further be described here. The shaft B is represented in Figs. 1 and 3 as having the two heads I) D. Each of these heads is shown as provided with four arms (Z cl (Z (Z the arms (Z (Z each having a yielding perforated tcmplet (Z adapted to carry a heel-blank into attaching position and drivers (Z similar to those described in my said United States Patent No. 694C565, dated March 4, 1902; the arms d (J have spanker blocks (Z and toplift holders (Z adapted to carry the toplifts into attaching position. I may use, however, heads having one templet only or any desired number of templets, or any desired number of arms with alternating templets and toplift spankers and holders. The bed a supports the two jacks E E, one faces to one front of the machine and one to the other. The jack E is arranged in operative relation to the head D and the jack E in operative relation to the head D. Each jack comprises a spindle e, a last or work support c mounted thereon, and a sleeve 6 for supporting the spindle extending upward from a base plate 0 which is shown as having lateral flanges to slide in grooves or ways formed in guide plates supported upon the bed a in order to permit each jack to be moved into heel-attaching position prior to the operations of attaching a. heel and topliftto the shoe, and to be moved out of such position thereafter to facilitate the removal of such shoe from the jack and the application of another shoe thereto. Under each spindle in the bed a is a hole 0'. In this hole at the bottom is a block of rubber e. I Upon this block rests a metal block 6 with an upward extended threaded spindle c and upon this threaded spindle 6 there is fitted an adjustable head 6 upon which the jack spindle rests. The shaft 0 has a gear f which rotates therewith and which is engaged by the pinion f fast upon the pulley shaft f Upon one side of the gear f is a member f of a clutch, the other member 7 of the clutch is arranged to slide upon a key or feat-her upon the shaft 0 and is moved into engagement with the clutch by means of the lever f and spring f; it is moved out of engagement with the clutch by means of the cam projection f upon the gear f and the latch f pivoted to the lever F. The latch is connected by a rod f with the treadle f. The gear f is free to turn on the shaft f and is rotated by means of a gear f upon the crank shaft 0 which is keyed or pinned thereon.

A desirable feature of the invention consists in the provision in a duplex machine of two heads or two sets of nailing devices adapted to conjointly operate, and which are arranged upon the same center or practically the same central line of the application of power to them; the center line in this case is the center of the shaft B. Another advantage arises from the location of the heads in relation to each other whereby the templets or heel-blank carriers and toplift holders or carriers are open and exposed and within easy reach of each operator, so that an operator standing in front of his jack may easily place the heels and toplifts in position upon the arms of the head which he is using, or if a boy or assistant is employed to place the heels and toplifts, then he may do so by standing upon the side of the machine opposite that of the respective operator, where he is in a very favorable position to easily and rapidly place them, and this advantage is the same of course whether oneor two heads be employed. Of course instead of two heads D D, one of sufficient width to carry two sets of nailing devices may be used. I would say that I do not confine myself to the special manner of turning the shaft B herein described; although I prefer that it be turned automatically.

Of course it is not necessary that the jacks be arranged as shown in Figs. 1, 2 and 3, as they may both face either front of the machine, in which event the operator or operators would stand at one front of the machine, and the attendant or attendants at the other; in other words, the shoes would be handled on one side of the machine only, and the heels and toplifts when placed by attendants would be placed upon the other side of the machine, and in Figs. 6 and 7 I have represented this construction. I prefer, however, to build the machine with two fronts, as shown in Fig. 1, for in this case the machine may be made very narrow, the jacks being quite close together. There the jacks both point the same way and the machine has but one front it must, of course, be wide enough to allow two attendants to stand side by side, one for each jack.

It will be observed that the boxes I) which bear or support the rotary shaft B, are represented in Fig. 1 as connected with each other by the section B, that is, the two boxes and the section B constitute a crosshead, while it is not necessary that the boxes be so connected, as the shaft B will in many instances be a sufficient connection.

It is desirable that the machine stop with the rotary heads in their highest or very nearly highest position, and to prevent their falling from this position after the disengagement of the clutch I apply a brake G to the shaft 0 It is represented in Figs. 1 and 3 as consisting of a curved bar 9 pivoted at g, and having its under surface lined with raw hide or other similar material and drawn forcibly against the hub of the gear f by the spring g (see Fig. 3), said spring being attached at one end to the bar 9 and at its other end to a stationary part of the machine. The toplift holder or carrier is represented in Figs. 4, 5 and 11, and comprises a spanker block having secured to the rear ends of its spanking face the V-shaped gage h by screws h, the gage h preferably having elongated slots 72. through which the screws pass and by which it is made adjustable transversely of the block (Z The block also has upon its face the yielding breast gage h, which preferably has the straight edge if and against which the breast of the toplift bears. This breast gage 7L is preferably made as an angle piece with the section /t which extends in front of the block cl, and is movable with the section h lengthwise of the block, being secured t0 the block by a sleeve [L6 which enters a hole 72 in the block, and through which a spring 7L extends, said spring being connected at one end to the front end of the sleeve and at its other end to the rear end of the block (Z thereby acting to draw the breast gage continuously toward the rear age.

It will be observed that each templet (Z which comprises a heel carrying device, is adapted to receive a heel in one posit-ion, to carry it into attaching position and to hold it in attaching position while the drivers (Z are operating to attach the heel-blank to the shoe. It will also be observed that each toplift spanking device or carrier is adapted to receive a toplift out of spankingor attaching position and to carry it into spanking or attaching position and there attach it to the previously-attached heel. During the movement of the carrier the top lift, which has been inserted by an attendant, will be securely held in place by the spring actuated clamping device above described and shown in Fig. 11. It will also be seen that the movements of the heel carrying and attaching device and of the toplift carrying and spanking device are in a vertical plane extending lengthwise of the shoe from heel to toe and that this brings the faces of the heel carrying and attaching device and of the toplift carrying and spanking device into a position confronting the operator or his attendant, so that he may see whether the heel-blank or toplift has been properly placed in its carrying device, and if it has been improperly placed he can then rearrange it. Not only this but the heel-blank carrying device and the toplift carrying and spanking device, being movable into and out of position lengthwise of the shoe rather than crosswise it, present and hold the heelblank and toplift in an accurate position in relation to the heel-seat of the shoe, that is, they are in longitudinal alinement with the part of the shoe to which they are to be at tached, and any slight imperfection in construction does not operate to throw the heel or toplift out of line with the shoe as it does where the heel-blank carrying and attaching device and the toplift carrying and spanking device are moved in a vertical plane transverse to the length of the shoe. lVhen said devices are moved transversely to the length of the shoe any slight variation in the lateral position of the heel and toplift, and especially the latter, causes unsatisfactory work. It will also be seen that each jack is supported for sliding movements into and out of heel and top-lift attaching position in a line parallel with the vertical plane in which the carrier moves. One advantage following from this arrangement is that it permits adjustment of the jack for accurately positioning the shoe beneath a heel or top-lift sustained by the carrier above the shoe, prior to the attaching operation, in the event that the carrier is not moved into the precise position required. It will further be seen that where a single nailing head, such as is shown in Fig. 8, is used, the reciprocating cross-head upon which it is mounted may be made very narrow and that the frame of the machine carrying the jack or work sup portmay also be made very narrow. This is of marked value in the construction of heel-attaching machines because it permits a very strong cross-head of relatively light weight to be employed, and it also enables a stronger but lighter frame to be used and less factory floor space to be required for the machine, thus obtaining a better machine because a stronger machine, a cheaper machine because a lighter one, a more desirable factory machine because more compact and having a smaller base',"and"a' more powerful machine because less power is required for moving the lighter though stronger crosshead.

The form of heel which the machine shown herein is best adapted to attach to a shoe is known as a loaded heel, that is, it is a heel in which the nails are partially inserted or driven. Such a heel detached is represented in Fig. 9.

The templet a which carries the heelblank into attaching position is provided with perforations corresponding substantially to the positions the nails occupy in the heel-blank, so that to apply the heelblank the heel on the templet with the nails in the heel protruding into the perforations in the templet. The perforations in the templet are slightly larger than the nails, as shown in Fig. 10, so that some of the nails will bind. against the sides of some of the perforations in the templet, whereby the heelblank is frictionally held to the templet or carrier as it moved from receiving into attaching position and is so held until the nails have been driven from the holes of the templet by the drivers (1 in the act of at taching the heel to the sole of a boot or shoe. The templet thus serves as a heel-holding and carrying device.

The top lift holder, per so, is not claimed herein but forms the subject-matter of divisional application Serial No. 572,4l8'7, tiled July 18, 1910.
