In order to Fig. 1. secure a slight yielding action between the jaw I4 Fig. 3 is a transverse sectional view through a and shoulder s this jaw is yieldingly supported in 50 portion of the machine of Fig. 1 showing the time spaced relation to the table top by the blade shaft. 7 springs H which may be clamped to the jaw and Fig. 4 on an enlarged scale is an end view of table top by the bolts shown. the heel supporting mechanism of. the machine The slope or curvature of the rear surface of of Fig. 1. heels may vary with variations in the styles of 55 the heels. Means is therefore provided whereby the jaw l5 may be adjusted angularly to cause its heel engaging surface to conform to the inclination of the inverted heel H and to this end in the construction shown the jaw I5 is provided with the laterally projecting ears |8 which are pivotally secured by the clamping bolts I9 to a slide or plate 20 mounted upon the table top I2 for adjustment transversely of the table towards and from the jaw 14 to firmly grip the-heels between these jaws. The jaw supporting plate 2|] may be secured to the table top by the bolts 2| extending through elongated slots 22 in the plate 20 and after the proper adjustment has been secured these bOlts may be tightened to firmly secure the plate 28 in place. The transverse movement of the plate 20 is preferably guided by the key 23 secured to'the table top. Adjustment of the plate 2|] towards and from the .heel gripping position may be secured by operating the adjusting screw 24 :Which is journaled in a bracket '25 secured to the table :top and this screw has threaded engagement .with the plate '20. The adjusting screw :may be rotated by means of the hand knob 26. As will be :apparent in Fig. 5 the jaw F4 is preferably somewhat longer than the jaw l5 to facilitate the placing of the heels flat the entrance between the jaws so that when the power operated plunger, to be described, moves forward "it will slide the heel along the table top between the substantially parallel jaws. The entrance end of the jaw |5 may be rounded slightly it-desired but this is not essential since the curvature of the heel will serve to guide the hee'l into the space between the jaws.

In the construction shown the heel when placed upon the table top l2 in an inverted position is forced lengthwise of the relatively long jaws by the reciprocating plunger 21 which is slidably supported by the bearing blocks 28 secured to the table top. The forward end of this plunger is preferably provided with a socket, as will be apparent from Fig. 2, adapted to adj-ustably receive the shank of the heel engaging member 29. The arrangement is such that this heel engaging -member may be adjusted longitudinally of the plunger slightly and clamped in the desired position of adjustment by tightening the set bolt 30 threaded in a projection upon the forward end of the plunger. This adjustment of the heel engaging member '29 is provided to vary the distance the heel will be moved lengthwise .of the jaws by the forward movement of the plunger 21.

In the construction shown forward movement is imparted to the plunger 2;! by a rocking lever 3|, the lower end of which is pivotally supported within the machine casing at 3'2 and the upper end of this flever extends through a slot formed in the plunger 21 .as indicated at 33. Forward movement is imparted to the lever 3| by a cam 34 keyed or otherwise rigidly secured to a transverse shaft 35 which willhereinafter be referred toias the time shaft. This shaft, as will be apparent from Fig. 3, is journaled in bosses 36 proyided upon the side walls ll] of .the Supporting frame. The shaft may be held from moving longitudinally in its bearing by .the driving sprocket 31 secured at-one end of this shaft and by .a collar 38 secured to the other end of this shaft. The cam 34 engages ;a roller 39 pivotally secured to the lever 13:! :and forces this lever forward to impart a working stroke to the plunger 21. This lever in the construction shown is retracted to return the plunger to the dotted line position of Fig. 2 by the spring 40 one end of which may be connected to the lever 3| and the other to the machine frame.

The time shaft 35 which is shown as disposed near the forward end of the machine is driven, in the construction shown, from a transverse shaft 4| disposed near the discharge end of the machine, and which will hereinafter be referred to as the clutch shaft. This clutch shaft has loosely journaled thereupon at the rear of the frame H], a driving sprocket 42 which is driven from a motor 43 by the chain 44. (Jo-operating withthe sprocket 42 is a clutch or disk 45 which is ,connected to the shaft 4| for sliding movement thereupon into and out of friction engagement with the outer face of the sprocket 42 and the sliding movement of this clutch element 45 into and out of friction engagement with the sprocket 42 is controlled .by the lever 45, the upper end :of which is :pivotally secured to a supporting bracket 41 secured "to the .casing and :the lower end .of this lever is operatively connected to :the :upwardly extending portion 48 of a foot treadle .49. Anintermediate portion of the lever 46 has "the enlarged hub 50 which is .operatively connected to the clutch member 45. The treadle .is pivotally supported at 5| upon a bracket 52 secured to the machine casing and the upwardly extending portion '48 of the foot treadle has an elongated slot adapted to receive a pin 53 secured to the 'lower portion of the clutch operating lever 46. The clutch is normally held in its inactive .position by a spring '54 and is held in friction engagement with the sprocket 42 to drive the shaft 4| :by depressing the foot treadle '49.

The time shaft 35 is driven from the clutch shaft 4| at .a reduced speed by providing a small sprocket 56 upon the shaft 4| adapted to drive a large sprocket 31 upon the shaft 35 by means of :a sprocket chain 51 to thereby .turn theplunger operating cam 34 .in the direction indicated by the arrow in Fig, 2.

The mechanism so far described serves to operate the plunger 21 to forcea heel .H along the table top from the position indicated by I in which it has :been :placed by hand at the entrance to the jaws l4 and I5 to a position indicated by II near the discharge 'endlof these jaws, as shown in Fig. 5. This will serve :to accurately position the heel H in the position II to be drilled and stamped :as will be hereinafter described. Whereupon the heel will be moved forwardly between the jaws by the next incoming heel to the position indicated by III, as shown in Fig. 5, in which position a heel strengthening dowel (1 may be driven into the drill hole formed in the heel while this heel was in the previous position indicated by II.

It is desirable to stamp heels during their process of manufacture with numbers or other marks indicating size and style and this is accomplished in accordance with the present invention by providing means for stamping the top surface of the inverted heel while it is in the position II of Fig. 5. To accomplish this in the construction shown the heel stamping dies 58 are positioned below the table top to pass upwardly through a hole 59 in the top of the table to engage the surface of the heel to be stamped. These dies are secured to an operating lever 60, one end of which is pivotally supported at El upon lugs or the like 62 extending downwardly from the table top I2 within the machine frame. Operating movement is im parted tothis leverIiIl by the cam 63 which engages a roller 64 rotatably mounted at the under side of the lever between the spaced ears 65 adapted to straddle the peripheral portion of the cam 63. The lever 66 normally rests in its lower or inactive position in which it is shown in Fig. 7 and is periodically raised by the cam 63 to stamp the heel H.

It is important to apply ink to the stamping dies 58 and this is accomplished in the construction shown by providing the inking roll 66 which is normally supported by the bracket 61 in the inactive position in which this roll is shown in Fig. '7. The inking roll 66 is caused to periodically wipe across the upper ends of the dies 58 by mounting this roll between the horizontally extending links 68 which are pivotally secured at 69 to the upstanding operating levers III, the lower ends of which levers are pivotally secured at 1| to a transverse brace II. Rocking movement is periodically imparted to the levers 10 from the lever 3| by the connecting link 12, and a spring 13 serves to force the inking roll 66 downwardly so that it will yieldingly wipe across the upper endsof the stamping dies.

As the heel H is advanced by the plunger 21 from the position inwhich it is indicated by I in Fig. 5 towards the position indicated by II it is acted upon by a rotating circular saw 14 which cuts off the end of the'heel to shape this end to receive the usual top lift. -The saw 14 in the construction shown is driven by .the motor 15 which is supported for movement in a substantially vertical direction towards and from the table top and also for angular adjustment, to thereby vary the height of the shoe heel and the angle at which the surface shall be cut to receive the top lift. The motor 15 is supported, in the construction shown, for the adjustments just mentioned by an angle plate 16 to the upright portion of which is pivotally mounted at 11 the angularly adjustable plate 18, and this plate is clamped in the desired position of angular adjustment by tightening the angle clamp 19.

The motor 15 is provided with a supporting head mounted upon-the angularly adjusted plate 18 for sliding movement and adapted to be adjusted towards and from the work by rotating the crank handle 8| to turn the motor adjusting screw 82. The circular saw 11 is shown as having the usual guards 83.

As soon as aheel H has been advanced by the plunger 21 to the position indicated by II in Fig. 5 it may be acted upon by the twist drill 84 which may be supported and operated by the drilling mechanism 85 supported upon the angle plate I3. This drill press has the driving motor 86 which by means of the belt 81 drives a drill operating spindle which is rotatably mounted in the hollow shaft 88 which is non-rotatably but slidably supported by the frame of the drill press. The entiredrill press is mounted upon the angle plate I3 at an inclination to the vertical to accommodate the angle at which the heel is to be drilled and the drill 84 isnormally held in its raised position by the spring 89. This drill is periodically lowered to drill the heel, in the construction shown, by providing upon the clutch shaft 4| the drill lowering cam 90 which is adapted to depress the lever 9|, one end of which is pivotally supported from the machine frame at 92. To the opposite end of this lever 9| is pivotally connected the link 93, the upper end of which is connected by the bolt 94 to a plate or casting 95 rigidly secured to the non-rotating drill shaft 88; The connecting link 93 is preferably constructed with overlapping parts which may be clamped in different positions of adjustment by the bolt 96, as best shown in Fig. 2, to vary the overall length of this link and thereby vary the degree to which the drill 84 will be forced downwardly by the operating mechanism just described.

The cams 63 and 90 are not secured to the clutch shaft 4| in the present construction but are rigidly secured to a sleeve 91 journaled upon the shaft 4| and this shaft is driven from the time shaft 35 by the chain 98 which passes around a sprocket 99 upon the time shaft and the sprocket I00 upon the sleeve 91 to drive this sleeve and the cams secured thereto.

In accordance with the present invention means is provided whereby when the drill 84 is lowered to drill a heel H in the position indicated by II a dowel driver will be operated at this time to drive a dowel d in a heel occupying a position indicated by III at this time. This is accomplished by constructing the casting 95 so that it will adjustably support the dowel driving pin IOI positioned to align with a hole in a heel occupying the position indicated by III. In order to secure the proper lateral and longitudinal position of the dowel driving pin IIlI the casting 95 is preferably formed as shown in Fig. l0 so that the pin IOI may be rigidly clamped by the bolt I02 in the pin supporting block I03 and this block may be adjusted towards and from the axis of the drill spindle and laterally by adjusting the different bolts I94. These various adjustments will serve to accommodate the distance which may exist between the two heels shown in Fig. 5 when one is being drilled and the dowel is being driven into the other.

In the construction shown the dowels to be driven in the heels are supplied from a hopper I05, which hopper may be supported above the frame of the machine by the upright I96. The dowels are fed from this hopper through the tube I01 which leads from the hopper to the dowel feeding device I08 which is supported by a bracket I99, as best shown in Fig. 6, directly above the heel in which the dowel is to be driven.

It is important that the dowels be supplied to the tube I01, one at a time in a continuous series. and this is secured in the construction shown by providing in the hopper I05 the dowel feeding trough III]. The upper end of this trough, as best shown in Fig. 12, is large enough to receive a stack of several dowels but as they slide down this trough the V-shaped groove thereof decreases in height as indicated by III to a size in which it will retain only one dowel and the other dowels will slide down the inclined walls II2 to be returned to the lower portion of the hopper. The single row of dowels that remain in the trough III are directed into the feed tube I91.

The dowels are delivered one at a'time into the dowel feeding device I08 directly in front of the forward end I I3 of the plunger II 4 which is slidably mounted in the hollow casing of the dowel feeding device I08. This sliding plunger H4 is periodically operated to advance a "dowel from a position directly below the feed tube I81, see Fig. 8, to the dowel driving position II5 and serves to hold the dowel in this position directly above the heel until the driving pin IIII is lowered and drives the dowel into the heel. When the slide I I4 is ,in its lowermost position a dowel supplied by thetube I01 will dropin front of the forward end of this slide and will be yieldingly held in this position by a spring I I6, the forward end of which extends through an opening in the side wall of the casing to engage the dowel.

When the slide I I4 is advanced from its retracted position of Fig. 8 a dowel entering the casing I08 will then drop upon the shoulder II! of the slide and will be held in this elevated position until the slide H4 is again retracted under the action of the compression spring H8 which yieldingly urges the slide to its retracted position against the stop H9. The means shown for periodically feeding the slide forward in its casing I08 comprises the flexible cable I29 secured at I2I to the slide and which passes around a pulley I22 and upwardly to the sliding shaft 88 of the drill press so that the upward movement of this shaft will tension the cable I20 and pull. the slide H4 forward. A spring I23 ispreferably connected to this cable to hold the slide yieldingly at the forward end of its stroke.

The means shown for elevating the dowels in the hopper I05 to supply the trough I III with these dowels comprises a vertically movable slide I24, the upper end of which is trough-shaped and slopes towards thetrough I I to cause these dowels to slide from the upper end of the slide I24 into the trough H0. Reciprocatory movement is imparted to the slide I24, in the construction shown, by the rod I25, the lower end of which is pivotally secured to the outer end of the transversely extending lever I26, as best shown in Fig. 6. The other end of this lever is pivotally secured at I21 to the supporting lugs I 20' and an intermediate portion of this lever rests upon the die operating lever 60. The arrangement is such that each time the lever 60 is forced upwardly by its operating cam it will raise the transversely extending lever I26 to thereby elevate the dowel feeding slide I24.

Having described the various parts of the embodiment of the invention shown, the operation is as follows: When it is desired to operate the machine the motor 43 is started and'the treadle 49 is held depressed to engage the clutch 45 and drive the clutch shaft 4|. This drives the time shaft 35 through the chain 51 and rotates the cam 34 to periodically operate the plunger 27 to cause the plunger to force a. heel H which has been placed by hand in the position I of Fig. longitudinally of the gripping jaws I4 and I5 to the position II, and feeds the heel past the saw I4.

While a heel is in the position II the drill 84 is lowered by the cam 90, lever 9| and link 93 to bore a dowel receiving hole in this heel, and when the next heel is forced along the jaws I4 and I5 by the plunger 21 it will engage the heel'that was last drilled and move it to the position III to cause a dowel d to be driven in the hole in the heel. The dowels are supplied by the hopper I05 and are successively presented to the heel by the device I08 in position to be driven by the heel by the pin IOI. Means is also provided whereby when a heel is in the position II the heel may be stamped by the dies 58. The cams 63 and 90 are driven at the same speed as the cam 34 by the chain 98.

After a heel has been acted upon by the saw 14, drill 84}, stamping dies 58, and has been strengthened by a dowel d driven in the heel by the pin "II, the heel is ejected at the discharge end of the jaws I4, I5.
