Under this aspect of the invention the pressing instrumentalities comprise an anvil and an opposed pressure member, forming a heel-holder, between which the blanks are stacked when assembled together, whereupon the pressure member is operated and the blanks are finally fastened together while under pressure.

Other Objects and features of the invention will be in part obvious from the anneXed drawings and in part indicated in connection therewith by the following analysis. The invention accordingly comprises the features and combinations' of parts having the unique relations of the members and relative proportioning and disposition thereof; all as hereinafter described and then [particularly pointed out in the appended claims.

The preferred form of the invention is illustrated in the accompanying drawings, in which:-

fFig. 1 is an elevation of the left side of the machine showing a general assenrbly thereof. Figs. 2 and 3 are enlarged upper and lower sections of Fig. 1 also in side elevation, but with portions of the frame omitted and with various parts broken away to show more clearly the details of construction.

Fig. 23 is a plan of two empty magazines taken transversely through the guide rods thereof to show the arrangement of the elevating i'inger. Figure 24 is a fragmentary side elevation of the parts pou'- trayedby Fig. 23. Figs. 25, 26 and 27 show various positions of the blank picker and of the means for frictionally gripping the upper blanks of the stack. i

Referring to the embodiment of the in-V vention illustrated in the drawings and continuing by way of amore detailed description of this embodiment, the various major submechanisms will be described in about the order in which they take part in lthe various manipulations of a heel lift, or other blank used for a: like purpose, in' the 'machine, thereby affording a better graspV of the general scheme of the organization.

The hand control for starting and stopping includes the lever'K (Figs. 1, 3, 5 and 7) extending upwardly from the base 1 of the machine at the left side thereof. This upright hand lever is pivotally supported at 2 (Fig. 5) by a bracket 3 and its lower end is pivoted at 4 to a long rod 5 (Figs. 5 and 7) that extends horizontally through the base towards the right side of the machine near which it is supported by the base-bearing 6 (Fig. 5). this hand-actuated long rod 5 are communicated to a rearwardly extending link 7 (Figs. 3 and 7) by means of a bell-crank lever 8 pivoted directly to the link 7 and indirectly to the long rod 5 by means of a short link 9. This transversely extending link 7 in turn is pivoted to the operating arm 10 of a vertical shaft 11 which is supported in bearings at the right of the center-line of the machine. Extending rearwardly from the upper end of this shaft 11 is an arm 12 (Figs. 3 and 7) that terminates in a yoke 13 having anti-friction rollers 14 bearing in the annular raceway 15 of a clutch-member 16 (Figs. 5 and 6) which is splined to the main driving shaft 17 and which, in the one position, frees said main shaft from the source of power, and which in its other position engages the clutch 18 of a power-driven gear 19, mounted on a sleeve 17 loose on the shaft 17, vso that in that event the main shaft is power-driven. l In this instance, the gear 19 receives motion from the main driving .pulley 20, which is connected to the sleeve shaft 17 through the first-drive gear 21 and the back gears 22 and 23 as shown in Fig. 5. Another loose pulley 24 may be arranged adjacent to the driving pulley 20.

. It will be readily perceived from this that when the handle of lever K is thrown tolwards the machine, 'or to the left viewing tomatically, as will shortly be described more fully. y

)Vhenever the main shaft'17 is driven, so

`also will the four cam-wheels X, Y, Z and )17.(Fig. 5)f be driven in the direction indi- ,catedy by the arrows thereon, and these cam` `wheels actuate the ten levers A, B, C, D, E,

y F, G, H, I and J, that control or eHect opervcalmanufacture of another type of heel )characterized by` a strongly curved or tapei-ed contour. This machine is `well adapt- Y ed for making either type of heel, as'it may embody las many different magazines as Changes in' the position of there are different sizes of lifts7 composing the heel, and these magazines may be of various sizes. t

The series of magazines may thus, as shown in Fig. 8,V be graduated in size progressively so as to retain the blanks or lifts suitable V'for the different parts of a taper heel, and these magazines are preferably arranged in concentric relation with an operating center which may be regarded as the axis of the machine.

These magazines may be formed of top and bottom U-shaped plates connected together by means of vertical rods to form a sort of cage. Thus, as shown by Fig.l 23,

the bottom may` consist 'of the member 25v creased size, and they all rest on a segmen Sli tal plate 29, which is supported by the col# lars 30*(Figs. `3 and 7) adjustablyv secured to the posts 31, as is shown irt closer detail by Fig. 24. This construction makes for a ready interchangeability of the cages as they may be replaced vby others differently pro'- portioned tofmeet-the demands of various styles of heels. Y

- The blank elevating, mechanism includes an elevator M for each magazine, shown best byy Figs. 1, 3, 21, 22, 23 andv 24.*This consists of a sleeve 32 circumscribing a vertical .rack-rod 33 that'uprisesnadjacent each cage L. This rod 33 has no end-wise movement except for the purpose of stopping the machine.l A suitably formed "blank-supporting Vfinger 34 'extends laterally 'between the two innermost guide rods 27,-through the opening 26. in plate 25, into'the interior of the magazine, and'it supports the overlying stack of blanks therein contained. v The elevator M rises at anautomaticall'y regulated -rate of feed' so as tokeep the uppermost blank of the stack alwaysnear or directly at the upper end of the magazine, so that as fast as one blank is withdrawn, another will as# sumeits place more or less approximately. In other words, about the saine level vwill always beV maintained at the upper end of the stack, but it is to be noted that the feed of this elevator Mzis'discontinuous rather than regular, in that skips may take place `in its intermittent action as'willl presently be described.

The means for intermittently i uplifting" the elevator includes: ay reciprocating shaft 35 (Fi-gs.A 2:1 and 22)lthat uprises parallel to the rack-rod 33. Bothfof theseshaftsork "rods .enter apertures in an uppermost 'frame ico vrio

portion 98 (Figs. 1, 7 and 19), and while the machine is' in operation the shaft 35 will at frequent periods have a short up and down reciprocation. Both of these rodslmay be rotated about their axes and thus form rock-shafts. A pair of pawls 3G and 37 are pivoted to the elevator M, and their engaging points are preferably spaced apart a distance greater than an even multiple of the tooth pitch of the rack-shaft 35, so that the one will be in tooth-engaging position when the other is riding over a tooth. Springs 38 (Figs. 21 and 22) normally urge these pawls into engagement with the teeth of the rackshaf't. Similarly a complementary pair of pawls 39 and 4() are pivoted to the elevator M and through apertures 41 therein enter into engagement with the teeth of the rackshaft 33. Springs 42, in like manner, serve to maintain the engaging ends of these pawls in operative relation with these teeth in a manner similar to that already specified. From this, it will be seen that an up and down reciprocation of the rack-shaft 35 (which is also a rock-shaft) causes the elevator M gradually to crawl upwardly until suitably stopped.

The means for reciprocating the rackshaft 35 includes a sleeve 43 (Figs. 18, 21, and 22) havingslots 44 in its upper end. This sleeve 43 loosely surrounds the rackshaft 35, and itis constantly reciprocating up and down thereon, so that whenever the radial slots 44 are aligned with the projections 45 extending from the rack-shaft 35, then no motion will be imparted to said rack-shaft, but when said projections 45 do not register with said slots 44, then the projections 45 will be engaged by `the upper edge of the sleeve 43, and the rack-shaft 35 will beelevated slightly.

This constant reciprocation of the sleeve 43 is maintained by a collar 46 that loosely surrounds the sleeve 43, and which` is connected by links 47 to the overlying end of a rock-lever 48 (Fig. that is pivoted at an intermediate point 49 to a suitable standard 5() rising from the base, and at its other end, vthe rock lever 48 terminates in a rounded end 51 entering the annular groove 52 of a common reciproca-tor 53. This reciprocator slides up and down on a shaft 54 uprising from the base of the machine, preferably in concentric relation with the several magazines, as it is used to actuate the elevators M for all of them, and it is pivotally connected tothe arm 55 of an operating lever A by means of a suitable link 57 (dotted lines in Fig.-3). This operating lever is ivoted at 58, and, at its upper end, carries a roller 59 that normally rides on the bottom of a cam surface X (Fig. 3) on the periphery of the camwheel X. At one point on its periphery, this cam-surfaceXa provides an. offset portion 62, that produces a periodic oscillation of the lever A, and the parts connected therewith.

The foregoing description, although given especially with reference to a single magazine L, applies equally to all of them, because they are all connected with the common reciprocator 53 in the same manner as with the magazine L., and the parts are merely duplicated, and, of course, the elements 53, 55, A, 59, etc., are all common to cach of the magazines.

The automatic stopfor the blank feed is for the purpose of discontinuing the operation of the machine whenever anyone of the magazines becomes nearly exhausted. This automatic action takes place whenever one of the stack elevators M impacts a pin or stop 63 (Fig. 19) projectingfrom the upper end of the rack-shaft 33. The effect of suoli impact is to uplight the entire rackshaft 33, Vmoving it in an axial direction, and this, through certain intervening mechanism,'throws the control shaft 11 in the same direction that it is turned by pulling out the hand lever l (already described) to stop the machine.

Referring to Figs. 17 and 21, it will be noted that the rack-shaft 33has secured to its lower end a collar 64, as well as an operating handle 65 and a gear segment 6G. Normally resting on the collar 64 is a part 67 secured to the lower end of a link 68 (see also Fig. 3), and, projecting from the other side of this lower link end, is a pin 69 that is guided by a slot 70 in a bracket 71 rising from the machine frame.V The upper end of the link 68 is in turn pivoted to a rock lever 72 (Fig. 3), fulcrumed in the bracket 50, that is normally urged by means of a contractile spring 73 in the direction needed to keep the part 67 on the collar 34. The other end of this lever enters between the cheeks 74 and 75 of a second vcommon actuator 7 6, which controls the mechanism that rends operative an automatic stop instrumentality.

The levers andV parts thus far described will be duplicated for each of the different magazines and, as will be perceived, slots 7 0 of the guide 71 enable any one of the magazine feeding mechanism to produce a shifting of the common actuator 7 6 without interference from any of the others. A relatively slight force will suflice to actuate these parts.

Vihen the common actuator 7 6 is depressed by an uplifting ofthe right hand end lever of the rock 72, the bell crank lever 77 will turn clockwise (as viewed by Fig. 3) producing a corresponding swing of the lever 78, through they agency of the resilient connection 79 which (as shown by dotted lines in Fig. 3) consists of a rod 80 having its head 81 telescoped by a sleeve 82, and heldin contractile relation byY an expansile springl 83.
