hlanlrs or bloc gure 1 is a side elevation of "the n1a' (i ii loo a prescribed number of lifts in a prescribed order in a pile, after coating them with paste, or any other adhesive, and who, upon completion of the assemblage, moves a presser head over it and then sets mechanism in operation which causes the head to bear against the assemblage and press the lifts firmly together. When the adhesive with which the lifts have been coated has dried or set, the heel is ready to be compressed in a heel compressor and thereafter applied to a shoe, or to be applied to a shoe directly without being previously compressed. llaving thus indicated the prod net for the making of which this machine is designed, I will now proceed with a description in detail of the machine.

1 is a base or bed designed to be set on the floor of a factory, or on any other supporting foundation, and on which are mounted uprights 2, 3, and 4c. The upright or frame 2 rises to a height convenient to the operator (who usually sits in front of the machine) and terminates in what may be called, for the purposes of this description, a table 5, around which are arranged the usual bins or compartments (not shown) containing the constituent lifts of a heel. This table in the machine here being descril ed, secures and positions a chute, in the mouth of which heels are built. A. filler block, later described more in detail, placed in the mouth of the chute and held there preferably by friction, provides the surface whereupon the lifts are assembled, and at that time and for that purpose is virtually a part of the table. A breast gage 6, rising at the front of the chute, assists the operator in alining the lifts while building the heel.

The chute occupies at its upper end, a central space in the table and is composed of four longitudinal bars; the front bars 7 and 8, of angle formation, which embrace the breast corners of the heel, and the rear bars 9 and 10, with concave curved interior surfaces which bear against the rear part of the heel at each side. This construction is of advantage because, since the bars may be adjusted toward and away from one another, the chute may be fitted to heels of all sizes and styles and caused to exert the de sired frictional resistance to their progress. It has another advantage in that spaces are left between the bars which accommodate the fingers or jaws of the presser head, later described. The rear bars 9 and 10 are hung from tile table by angular straps 11 and 12, respectively, having vertical arms which are bolted, or otherwise suitably secured, to the bars, and horizontal slotted arms which lie on the table and are secured by bolts 13 passing through their slots it and into the table. Retainer guide plates 15 secured beside and forward of the horizontal arms of these straps limit their freedom of movement to a straight crosswise line. Thus the rear bars are adjustable only laterally, or crosswise, and not to front and rear.

The front bars are adjustable both cross wise and to front and rear, and thereby the chute may be adjusted to heels of diife 'ent widths and lengths, but the position of the rear point as to h els of all sizes remains approximately the same, A cross bar 16 cccupies transverse notches 17 (shown dotted in Figure 3) in the front sides of the front bars 7 and 8, and is retained therein by blocks 18, bolted to the front bars and overlapping such cross bar, with enough freedom to permit lateral sliding movement of the front bars. The ends of the cross bar rest in guideways 19 running from front to rear in the edges of the wings of the table which flank the central space previously mentioned, and are retained by the overlapping edges of the guide plates 15. Thus the front bars of the chute are also hung from the table. iidju "tinents of the front bars rearward and forward are made by sliding the cross bar 16 to front or rear in these guideways, while set screws 20 threaded through lugs 21 at the front edge of the table hold the f ont bars a iinst the heels of the size to which the chute is adjusted, with such pressure as is needed to make the heels firm. he side bars (each front and rear bar at c aher side of the chute being a pair of sine bars within the meaning of that "erm now used) are li :ewise adjusted to the width of the heel and held against spreading, by lateral adjusting screws 22, 23 thremled through webs 2d and 25 at the sides of the frame 2 beneath the taole, which bear against longitudinal bars 26 and 27 confined between the outer faces of the side bars and said adjusting screws S and Each of said longitudh a1 bars rests on a pin 28 projecting from the side of the adjacent front bar, and on the head of the bolt which secures the corresponding rear bar to its supporting strap. The longitudinal bar is also notched in such a way as to provide a shoulder 29 to bear against the adjacent strap 9) and prevent the bar from working out of place.

l is u her prevented from i ie chute i spreading, and ad usted to the size of heel being made, a a lower point, by means of a front set shew 30 and side set screws 31 held by a haped stra or guard 32, which ast to the upright iraine 2, and t1 st, respectively, a plate 38 in front of the chute, and side plates at the sides of the chute. The rear bars to the u A cross rod 1-6 l t 32 supports the forward on e plates, and they in turn sup-poi the 1';- t plate.

The breast "a e 6 1s )lOVlClGCl b two til) plates rising from the front bars of the chute, to whichthey are secured by splice plates 37 and screws, being removable to perinit substitution of appropriate gages for heels of different heights. A top gage 38, having a short projecting lip, is secured to the top of the breast gage and informs the opei'i'itorwhen a heel has been built to the required height.

A presser head i is provided to aline or centralize the lifts and apply pressure end wise to the heels, forcing them into the chute. To this end, the head is movable, both laterally from a position at the rear of the chute to one directly over, and vertically in line with, the chute. It is carried by a log arm all pivoted by a pin 42 to a slide -16 which travels in a guideway at the rear of the upright frame 2 and parallel to the chute. The means connecting the head to this arm is a lateral arm 4-5 secured to the upper end of the swinging arm, and a shank 46 Ontlifi headpassing slidingly through the lateralarm and limited as to its downward moven'ient by a stop block 47 fittedadjustably on the shank and secured thereto by a set screw 48. it guide pin 49 rises from arm through the stop block and prevents the head from rotating in this arm. A handle 50 for the grasp j of the operator enables the head to be swung forward over the assembled heel. t is non molly drawn back to its retracted position (shown in Fig. 1) bya spring 51 connected to the swinging arm 4:]. and anchored to an abutment rod 52 extending rearward from the slide 43. Fingers or jaws 52, 52, at the sides, and 53 at the rear, of the head depend therefrom and centralize the lifts of the heel assen'ibla re when the head is pulled forward. The side jaws then wipe along); the sides of the heel and the rear jaw comes to bear on its rear edge, applying pressuii'e laterally to the lifts in the most eillcient manner to shift them upon one another in case they should have been imperfectly located in the first place. The condition just suggested usually obtains in practice for the demands of rapid production forbid the operator to take time for nicely placing the lifts; but the provision oftlie cei'itralizinp; jaws makes it unnecessary for her to do so, since the jaws will take care of any such irregularities as occur in ordinarily skillful rapid heel building. These jaws have inner edges suit-ably inclined or disposed to conform to the taper of the heel being built; and they are detachably cured to the head, in grooves 54; in the sides thereof by clamps 55,56, and screw 57, to'perinit substitution of others adapted to any style of heels, whether straight or tapered more or less. The attac'iiing means just described locate the jaws to come in line with the spaces between the bars of the chute when the head is brought into its operatire position, while the guide pin 49, cooperating with the stop l'ilocli H, prevents any such rotation of the head as would then cause disalincinent of the jaws from such Spaces.

Adjustment of the shanlc' 4:6 in the step block i? allows the head to be placed more or less below the arm (which always at approximately the same lieight in the normal position of rest, representedin these drawings) prior to the compression stroke, and thereby located in a path wherein the jaws, when the head is pulled fOiWttY-i will bear on the edges of the particular heel, wiietiier high or low, being built. find dif ferent heads, suited to heels of various horizontal dimensions, maybe substituted for one another upon the arm ii The lateral arm may also be adjusted across the swinging arm to bring the head into exact alineinent with the chute,and for that purpose it has a tongue and-groove sliding engagement, indicated by (letter lines at 511 in Figure l, with the upper end of the swinging; arm, and is retained thereon by links 521 pivoted by a pin 531 to the swinging arm, and a clamp passing over the reduced and threaded ends ofsucli links and retained thereon by n'uts Power mechanism under the control of the operator gives the head its downward compressing Stli'OliQ. This mechanism consists of a belt pulley'ohl, loosely rotatable, and adapted to coact with a friction clutch member 571 on a shaft -58, which carries a pinion 59 meshing with a large gear 60 on a shaft 61. The latter shaft carries a pinion meshing with the gear 68 on a shaft Get, which is rotatable independently of shaft 58. G11 the shaft 64 is a crank arm 65 having crank pin 66 (Figs. 10 and 11) which occupies a block (57 arranged to slide in a transverse guideway in the res side of the slide id which carries the swin ing arm whereon the presser head is iiioun ed. Th shafts 58, (31, and Get are arranged in suitable bearings 69 and 70 on the uprights and dwhich rise from the base i. This mechanism gives a continuous speed reduction and power multiplicationfrom the source of power to the point of delivery upon the head-carrying); slide.

After the head has been brought into alinenicnt with the chute it is retained there during th v PJTQSSlHg stroke, by a dog (1 "w pivoted by a pin 72 between two brackets '73 which extends rearwardly from the upright. frame 2 on both sides of the swinging arm 41.. A spring T4: (Fig. 12) acts on the dog; pressing its free end toward the arm 41, and serving to turn the dog until itsend face abuts against a wear plate 75 on the arm when the latter is drawn forward, as shown in Fig. 12. Lips formed by a plate 76 secured to the dog crosswise then rest on the brackets 73, arresting movement of the dog. The length of the latter is such that when in the position last described it holds the carrier arm 41 vert cal, or in other words, in alinement with. the path in which it travels during the compression stroke of the head. A feature of the dog is that, being unrestrained except by the light spring 7 1- from upward movement, the friction of the wear plate against. its end when the presser carrier rises, is enough to swing it back into its inoperative position, where it permits backward displacement of the carrier arm 11. Its inovenient in this direction likewise is limited. by the wings '70. Furthermore, if the operator in swinging the presser head forward, should release the latter before having brought it to the extreme limit of forward movement, but yet far enough to let. the forward end of the dog drop enough to secure the head against backward swinging, then the friction of the wear plate on the dog in the downward stroke becomes effective to place the dog fully in its operative p sition.

For clutching the drive pulley 561 to the transmission mechanism through the clutch member 571, there is provided a treadle 7 8 convenient to the operators foot on the end of a treadle arm or lever 79, pivoted at 80 to an upright 81 on the bottom plate. This lever has a short arm 82 carrying an adjustable stud 83 arranged to press on the hub of the pulley and shift the latter endwise so that the cluth face with which. it is provided, complemental to the face of the clutch member 571, is crowded against the latter. hen depressed, the treadle arm is held in that position until released by the arrival of the carrier at the end of its, upward travel. It is so held by a latch 84: on one arm of a lever 85, the other arm of which has a cam or wiper element 86 cooperating with a pin 87 projecting from a bracket 88 on the slide 13. A spring 89 holds the lever with its wiper element against the pin 87 and tending to carry its latch element toward the treadle arm, and over said arm when the latter is depressed. lVhen the carrier slide descends after depression of the treadle, the descent of pin 87 past the inclined cam surface 86 allows lever to be moved in this manner and to catch the treadle in its depressed position. When the carrier rises, the pin 87 by wiping along the cam surface 86 moves the latch lever 85 in the reverse direction and allows the treadle arm to be raised by a spring 90. This occurs when the presser carrier is near the top of its travel, and then a brake 91 is applied to the disk which carries the clutch element 571. This brake is carried by a lever 92 pivoted to a bracket 93 on the upright 1 and pressed by a spring 94; toward the adjacent face of the disk. The treadle arm carries a wedge 95 which, when the treadle is depressed, crowds the lever 92 away from the disk and releases the brake, and when withdrawn by rise of the treadle arm, allows the brake to be applied by spring 94:. Hence the operator need give no further attention to the power operation of the machine than to depress the treadle,

and immediately after the head has started 96 on the upper end of the arm 97 which is pivoted by a pin 98 to a bracket 99 attached to the front bars of the chute. The attaching means comprises a slotted base plate 100 on the bracket, through the slots of which clamping bolts 101 pass into said front bars. The hook or finger 96 slightly overlaps the breast edge of a heel inserted in the chute. It is yieldingly held in that position by springs 102, and its upper side adjacent to the end is beveled so that the pressure of a descending heel will push it forward out of the way.

The filter blocks previously referred to perform an important function in the operation and effect of the machine, and constitute important parts of the machine combination. One construction of such block, designated 103, is shown in Figure 1 1, and another construction of the block designated 104: is shown in Figure 15. The blocks are of wood, or other sufficiently firm, strong, and durable material, preferably impreg nated or coated with a substance, such as parafiin, which makes them repellent to the adhesive with which the heel lifts are coated, so that they will readily separate from the heels upon emergence from the chute. In outline they conform approximately to the largest lift of the heel, and those provided for use in building tapered heels are wedgeshaped to bring the upper face of the tapered heel horizontal, for such heels neces sarily have their opposite end faces disposed at an angle to one another. The chute is adjusted to fit the spacing blocks and to apply pressure to the corners and each side thereof. Thus frictional resistance is exerted against the passage of the blocks through the chute, and this resistance must be overcome by pressure applied by the head 40 through the heel. This pressure coinpresses the lifts of the heel together; and it is maintained and augmented by successive filler blocks and heels built on top of one another and successively forced into the tlti chute. When the chute contains a long series of heels and blocks, the cumulative frictional resistance of all the blocks must be overcome in putting each new heel into the chute, and the overcoming of this resistance necessitates applying relatively great pressure to the new heel. Thus, the heels as soon as assembled, are put and maintained under pressure; and the chute is intentionally n'mde long enough with respect to the time required for drying or set ting of the adhesive to enable such adhesive to dry or set before the heel emerges from the lower endfof the chute, it follows that the heels are held strongly compressed until they have dried. llhe retainer 96 contrib utes to this end by preventing relaxation of the pressure upon the heel last assemoled after it has been forced into the chute, and before the next new heel has been pressed against it. Hence there is no intermission of the pressure and no opportunity for the bond of the adhesive to be broken or weal:- ened at any stagein the course of drying.

The difference between the two types of filler blocks shown in. the drawings consists in thatthe block 103 has longitudinal rib 105 on its upper surface designed to limit the area of contact with the adjacent lift of the heel, while the block 104 has no such rib. Fach block has a notch 106 in its breast end desigi'ied to receive the retainer hook 96, so that it may rest squarely against the last heel placed in the chute, without causing or requiring displacement of the retainer. v

The machine and its chute are made for use in the vertical. position, and the table is arranged horizontally because this is the most convenient arrangement on all ac-' counts, as well for the operation of building heels as because it enables a chute of sullicient length to be provided by extending it through the floor on which the machine is installed to a lower floor or the basement of the factory. llut nothing in the way of limitation of the scope in which I claim protection is to be implied therefrom, since the principles of the invention may be embodied in machines otherwise arranged and operated, as forexample, in a horizontal position or at an inclination.

lit is to be observed that certain features of the invention, particularly those residing in the presser head, its mode of action, its :arrier, and the operating means therefor, are-not necessarily limited to the combination and use with a chute machine, but are applicable to machines having fixed tables as well,

The mode of operation of the machine has been suiliciently understood from the foregoing description to make unnecessary any special statement of operation. It is sufficient to say that the operators part con sists in assembling the lifts of a heel upon the filler bloclt placed over the last built h el, in then pulling the presser head for ward over the complete assemblage of lifts, thereby rausing the aws and 53 to aline or centralize the liftswith one another, and in. finally depressing and releasing the treadle. Thereafter the mechanism automatically lower the presser' head, forcing the new heel into the chute'and propelling the whole series in the chute one stage forward, and then raises the head and stops with the head in its raised and retracted position shown in the drawings.

Figures 18 and 19 show an alternative construction of the topgage 38, shown by Figures 1 and 2. The top gage, instead of being composed of asingle piece attached to the plates 61, forming the breastgage, and having no vertical adjustabi'lity', is composed of two pieces 38 movably'secured to said slates and'adjustable vertically to conform to heels of differentheights, the plates Ghaving vertical slots 6, and the top gage ieces being secured to the plates 6 by clamping screws 38" passing through said slots. 7

Figures 18 and 19 also show oppositely 1nclined side gages 38 adapted to bear on opposite sides of a heel h, the breast and top of which bear respectively on the breast gage and the top gage. The side gages are adjustably secured by screws 38 passing through slots 38 in thebase portions of the side gages, so that said gages are adjustable toward and from eachother 'lhe chute bars may be so adjusted or spaced, that the filler'bloclrs are loosely movable in the chute, so that there is no frictional resistance to their movement in the chute,
