Specification of Letters Patent.

PatentedNov. at, 1919.

To all whom it may concern Be it known that I, ERVIN L. PAGE, a citizen of the United States, residing at Georgetown, in the county of Essex and State of lVIassachusetts, have invented an Improvement in Heel-Lift-Cementing Machines, of which the following is a specification.

This invention relates to certain improvements in heellift-cementing devices which, while adapted for general uses, are especially designed and adapted for use in connection with a heel-lift assembling machine, of the type shown in my Patent No. 1,223,728, dated April 24:, 1917 and employing an endless carrier composed'of a series of heel-lift holding and clamping devices.

Prior to my invention, the almost universal practice has been to arrange the heellifts in a series of compartments, from each of which the heel-builder removes a lift, applies cement thereto, usually by dipping, or With a brush, and then places them in a heel form. Other means designed to perform this operation more rapidly have been devised, but, so far as I am aware, none of them have been found to be practically efiicient.

The object of my invention is to provide a form of cementing device for the heellifts which will automatically cement the set of lifts required to build any particular heel, and deliver the same, each time a set is required for the assembling machine, at such a point that the cemented lifts may be rapidly assembled in the heel form.

I accomplish this object by providing a series of heel-lift receiving compartments, vertically arranged side by side in a row, and adapted to contain the different heel-lifts required, and by further providing a. separating device which simultaneously removes the lifts from the bottom of each stack, passes the same over a cementing roll, so that a coating of cement is applied thereto, and delivers them upon a receiving table closely adjacent the form in which the lifts are to be assembled, so that they may be readily collected by the operator and placed in the form, and by providing means whereby said separating device is automatically operated each time the carrier of the assembling machine is advanced, so that a set of cemented lifts will be delivered each time a set is re" quired by the operator;

For amore complete understanding of my invention, reference is made to the accompanying drawings, in which Figure 1 is a side elevation of a heel-lift cementing and assembling machine embodylng my lnvention.

Fig. 2 is a cross-section 011 line a2a2 of Fig. 3.

Fig. 3 is a plan view of the cementing device.

Fig. 4 is a front View of the lift-holding tray.

Fig. 5 is an enlarged sectional view on the line 50-122 of Fig. 3.

Fig. 1 of the drawing shows the general method of application of the cementing device to the assembling machine, said machine comprising an upright frame 2 having an endless carrier, consisting of a series of flexibly connected heel-holders 4, and being adapted to be intermittently driven through a clutch-mechanism on shaft 8 by the main shaft 7, the carrier being advanced the length of one holder each time the treadle 9 is depressed.

The means for cementing and delivering the heel-lifts, comprises a lift-holder 315 which is mounted on the frame 2 at the rear side thereof, said holder having a series of vertically disposed compartments 36 therein, each adapted to hold a stack of heel-lifts therein and arranged side by side, in a line which extends longitudinally of the frame and in a direction parallel to that in which the carrierthereof is driven, said compartments varying in size according to the various standard sizes of lifts which are usually employed in forming heels, the size of the compartments decreasing from one end to the other, according to the decreasing sizes of the lifts to be placed therein. A sutlicient number of compartments are provided, so that, by removing a single lift from. each compartment, the necessary lifts for building the highest heels will be secured. The number of compartments which will be used under any condition will correspond to the number of lifts in the particular heel to be built.

A horizontally disposed, lift-supporting table 37 is arranged directly beneath the lower ends of said compartments and extends longitudinally throughout the length of the line thereof and transversely from a point in the rear of the holder to a point approximately midway of said compartments. A cement containing tank 38 is arranged directly beneath said table, and extends throughout the length thereof, and has a cementing roll 39 rotatably mounted therein, which extends from one end of said tank to the other and is arranged to extend slightly above the level of the supporting table 37 in close proximity to its front edge, so that the bottom lift of each stack will be supported partly on the table 37 and partly on the roll 39, as best shown in Fig. 5. Suitable means for driving said roll 39 continuously are provided, said means comprising a pair of bevel gears i0 which are driven by a belt i1 from a pulley on the main shaft 7, said roll being preferably driven so that its upper portion moves away from the adjacent edge of the table 37, and tends to move the lifts forwardly toward the machine. The tank 38 is kept partly filled with liquid cement, by means of the sealed reservoir 52, so that the roll constantly dips in the cement. A lift-receiving table 42 extends in front of said roll 39 and is arranged be tween the holder 35 and the frame 2 at the level of the upper edge of the latter and closely adjacent said roll 39 at the opposite side thereof from the table 37, the width of said table being approximately equal to the length of the largest lifts.

A heel-lift separator, or pusher 43 is provided, comprising a flat plate arranged to slide on the surface of the table 37, and extending the entire length of the table 37, said plate being of slightly less thickness than that of the heel lifts which are to be placed in the holder, a space between the lower end of the holder and the table 35 being provided to permit said plate to pass therebetween and engage the lowermost lift of the stack and slide it from beneath the stack, in a well-known manner. An eccentric rod 44 is pivoted at one end on the pivot 14: and forked at the opposite end to engage an eccentric on the shaft 8. A rock shaft 4-5 is mounted on brackets 4-6 in the rear of the frame, and an arm 47 is secured thereto and is provided with a bolt 48 at its free end, which extends through the rod 4% and a spring 49 is arranged on said bolt 48 between the rod 44 and the arm 47, so that, when the rod it is oscillated, the arm 47 will be swung correspondingly. A pair of arms 50 are secured on the shaft 45 and are loosely connected to the separator 43 by pins 51 which pass through slots in said arms at their opposite ends.

The operation of the above described device is as follows The compartments 36 are filled with heel lifts, as illustrated in Fig. i, the bot tom lift of each stack resting partly on the table 37 and partly on the roll 39, as before described. When the operator steps on the treadle 9 to cause the shaft 3 to make a complete rotation and drive forwardly the carrier, so that the heel form which has ust been filled will be moved on from the liftreceiving position, directly in front of the middle of table 42, the rod 44 will be swung downwardly on its pivot, causing the arm l? to be moved downwardly and the arms 50 to be swung forwardly, moving the separator4-3 beneath the stacks and, simultaneously, pushing a heel-lift from beneath each stack of lifts over the cementing roll 39, so that the latter may deliver them onto the receiving table 42. As the lifts pass over the cement roll they will be thoroughly cemented on their under sides by said roll, and delivered in the order in which they were stacked onto the table 42, so that the operator has merely to pick up the lifts, in order, and place them in the heel form on the particular heel-holder which is then in lift-receiving position. In case of clogging the spring 48 will yield, preventing straining of the parts.

lVith the above described construction the lifts necessary for constructing the heel are thus automatically cemented and delivered at a convenient point, each time the assembled machine is operated to clamp a set of lifts on a holder, and therefore,each time a fresh set is needed.

The cementing and assembling operation may, therefore, be rapidly performed.

To provide a convenient means for filling the lift-holder 35 with lifts, the rear half of said holder is made in the form of a tray 35, whiehis removably mounted on a rearwardly projecting portion 35 of the fixed portion of the holder and is adapted to be held in position by hooks, as 53, (shown in dotted lines in Fig. 2), so that, to fill the holder the tray is removed and laid flat on its rear side and the lifts are placed on edge in the troughs 36, thereof, which form the rear portions of the compartments 36. The upper endsof the troughs 36 are closed and a rod 5% is provided, which is inserted in the bottom end of the tray throughout the length thereof, before the lifts are placed therein, so that the lifts will be prevented from falling out of the tray when it is returned to an upright position. After the tray has been secured inplace the rod 54 is drawn out, permitting the lifts to fall into the lower ends of the. compartments, so that they are supported on the table 37 and roll 39, as already described.

. By providing several trays for each machine, one tray may be filled while another is on the machine, so that its operation will not be interrupted when a fresh supply of lifts are furnished.
