' JAMES A. BROGAN, 0 F LAVWRENCE, MASSACHUSETTS, ASSIGNOR "IO U'NITED SHO'E MACHINERY COMPANY, OF PATERSON, NEW JERSEY, A. CORPORATION OF NEW JERSEY.

To all 4072 out it may concern:

Be it known that 1, JAMES A. BnoeAN, a citizen of the United States, residing at Lawrence, in the county of Essex and State of lvlassachusetts, have invented certain new and useful Improvements in Machines for Laying Soles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

T he present invention relates to sole layin machines. I

Heretofore it has been the practice in layingsoles, after cement has been applied to one or both of the engaging surfaces of "sole and shoe and the sole has been properly positioned upon the shoe, to apply pressure to the sole simultaneously throughout substantially its entire surface, and the machines of the prior art have operated in accordance with the above described process. Inasmuch as the wooden lasts upon which the shoes are supported during the laying operation are obliged to sustain at one and the same time the total pressure applied to the entire sole, these lasts are liable to be broken or otherwise damaged. As a result the pressure per unit area which may be applied to the various portions of the sole is limited and difficulty is experienced in properly laying the sole, particularly in the shank.

One of the objects of the present invention is to produce a machine for laying soles in which a high pressure per unit area may be employed yet without danger of damaging the lasts. This object is accomplished, generally speaking, by applying the pressure to first one portion of the sole and then to another, the total pressure applied at any one time never exceeding the strength of the lasts. Preferably this pressure is applied by a rocking or rolling form or pressing member which operates progressively along the length of the sole, this method or mode of operation having the further advantage of spreading the cement and forcing out any surplus cement or air bubbles.

Another object of the present invention is to produce a machine for laying soles in which the sole is held in proper position on the shoe while pressure is being applied and this is accomplished by holding or clamping Specification of Letters Patent. P te ted July 13, 1915.

one portion of the sole against the shoe while pressure is being applied at another portion. Other objects'andfeatures of the invention will be set forth in connection with the following description of the illustrated embodiment of the invention.

In the accompanying drawings Figure 1 is a side-elevation of a sole-laying machine embodying the present invention; Fig. 2 is a side-elevation, on a larger scale, showing particularly the jack and toe-clamp, with the toeclamp in operative position; Fig. 3 is a side elevation on a still larger scale, showing the toe-clamp and its, actuating mech anism in operative position; Fig. 4 is a similar view showing the toe-clamp in inoperative position; Fig. 5 is a front-elevation of the jack and the toe-clamp mechanism; Fig. 6 is a side-elevation of the toe-clamp lever; Fig. 7 is a detail plan-view of the trip for the toe-clamp mechanism and Fig. 8 is a front elevation, and Fig. 9 a side elevation, of the trip lever for actuating the toe clamp lever, with a portion of the handle bro-ken olf.

cation but is illustrated only in so far as is necessary for an understanding of the operation of the machine.

The present machine, like that of the patent referred to, is a twin or double machine, having duplicate parts so that while one shoe is being subjected to the laying operation 'by one set of instrumentalities, the other set of instrumentalities are in a position of presentation, that is to say, a. position in which the operator may remove and replace the work. In the drawings, however,

only one set of instrumentalities is illustrated, namely, those at the, right-hand side of the machine.

As shown in Fig. 1, the form is carried by a swinging arm 11 which is pivoted at 12 upon the frame 1 3 of the machine. The

jack is carried by an arm 14, which is pivoted at 15, on the frame of the machine. The arm 14 is oscillated about its pivotal support by means of a link or connecting rod 16, of which the upper end is pivoted to the arm while the lower end engages a crank 17 on a crank-shaft 18. The arm 11 is oscillated simultaneously with the arm 14:, by means of a link 20 which is pivoted at its lower end to the arm 14, and at its upper end to an arm projecting forwardly and integral with the arm 11.

Upon the crank-shaft 18 is fixed a gear 19, which is rotated by a worm 21. The worm is carried by a power-shaft 22 journaled in the frame of the machine. Upon the power-shaft a pulley 23 is loosely mounted, the pulley being movable both rotatively and longitudinally on the shaft. This pulley is constantly rotated by a belt (not shown) connecting it with any suitable source of power.

When the machine is out of operation the pulley rotates freely, but it may be operatively connected with the power-shaft by means of a clutch comprising a conical memher 212 fixed to the shaft, cooperating with a corresponding recess in the pulley. The pulley is provided with an annular groove on its hub, which is engaged by the forked upper extremity of a shipper-lever 26, and by these means the pulley may be moved into engagement with the clutch member 24. The lever 26 is fixed to a. rockshaft 27, which is provided also with an arm 28 connected by means of a link 29 with a lever 31. The lever 31 is fixed on a rock-shaft 32, and is provided with a roller 33 engaging a cam 34. The cam is fixed on a rock-shaft 35 provided at its forward end with a treadle 36. When the treadle is depressed by the operator the cam raises the lever 31 and through the connections described throws the clutch into operation so as to rotate the power-shaft and actuate the jack and the form.

The rock-sh aft 32 is provided with an. arm 37 having a cam-roll 3S engaging a cam 39 on the crank-shaft 18. When the treadle is raised by the operator to stop the machine a spring 41 connected with the arm 37 tends to raise the arm, and a spring 42, connected with the shipper-lever, tends also to move the latter to the left and disengage the clutch-members. The cam 39 acts, however, to prevent such disengagement until the mechanism has moved to a position in which the ack and the form are in their forward inoperative position or position of presentation. W hen this position is reached, the cam-roll 38 is free to enter a depression on the cam-surface and the mechanism then comes to rest. A brake 4-3 isconnected with the clutch-mechanism and is adapted to engage a brake-disk 44: on the power-shaft when the clutch is disengaged so as to arrest the machine immediately.

The sole-pressing form 45 consists preferably of rubber or other yielding material and is shaped to conform transversely to the required shape of the sole. The form is shaped longitudinally to engage the sole progressively as the jack and form are rocked. The form is removably secured in a carrier or bed 46 which is pivoted at 4:7 to a head fixed at the lower end of a stem 49. The stem 49 slides in a socket in the arm 11, and is pressed downwardly by a spring 50, shown in dotted lines in Fig. 1. The downward movement of the stem is lim ited by a stop-screw 51 threaded into the head 48 and engaging a lug 52 on the arm 11. The bed 46 may be adjusted about its pivotal support by means of two screws 53 threaded into the head 48 and engaging the bed.

The construction of the jack is illustrated particularly in Fig. 2. It comprises a basemember 5-1, mounted upon a stem which is seated in a socket in the arm 14-. The stem is normally fixed in the socket by a screw 56, but it may be adjusted verticall y therein by means of a screw 57 engaging the lower end ofthe stem.

The jack is provided with a heel-post 53, upon the upper end of which is pivoted the usual heel-pin 59 adapted to enter the socket in the heel of the last. The heel-pin is pivoted, at 61, on the heel-post, and a spring 62 acts normally to tilt the heel-pin forward so as to press the toe of the last against the toe rest.

The heel-post is adjustable on the base 5-11, according to the length of the last to be supported, and to this end it is provided at its lower end with flanges 63 embracing a guide er on the base.

The toe-post 65 carries at its upper end the toe rest 66. The toe rest is supported by a universal joint in order that it may conform to the various shapes and sizes of lasts employed. To this end the toe-rest is pro vided with a lug 67 pivoted in a yoke 68, and the yoke is pivoted, in turn, between lugs 69 at the upper end of the post. The toe-rest is normally retained in upright po sition bv means of a plunger 72, see Fig. 4-, which slides in a socket in the toe-post and engages a flat surface 71 on the bottom of the yoke 68. This plunger is pressed upward by a spring 73 shown in dotted lines in Fig. 42. The toe-post is mounted adjustably on a guide on the base-member A lasted shoe 7 5 is mounted upon the jack as shown in Fig. 2, and the heel-post and toe-post are moved toward and from each other to accommodate them to the length of last. In changing from one size of last to another it is not necessary,in all cases, to change the form employed in connection which is pivoted at 78 on the base-member 54C of the jack, and the lower end of the lever 77 is connected by a link 79, with the heel-post. To permit a greater range of adjustment, extra holes 81 are provided in position to receive the screws 90 by which the links are pivoted to the posts.

To fix the posts in adjusted position, I employ a latch illustrated particularly in Figs. 3, a, and 5. The upper surface of the guide is provided with rack-teeth 80, which are engaged by a tooth at the lower end of a latch 82. The latch slides in a recess in the toe-post and is pressed down by a spring 83. The latch has an upwardly projecting stem 84, which is notched at its upper end to receive a pin 85 projecting from a lever 86. The lever 86 is pivoted at 87 on the toe-post and it has an upward extension 88 constituting a handle by which the lever may be swung to disen age the latch from the teeth 80 when the jack is to be adjusted.

T 0 hold the heel-end of the sole in position on the shoeduring the operation of the form on the other parts of the sole, the pres ent machine is provided with a heel-clamp 89 mounted on an arm 91 which is constructed and operated the same as in the case of the heel-clamp of the Mayo patent hereinbefore referred to and further description of this part is not, therefore, necessary herein. To hold the toe-end of the sole in a similar manner, the present machine is provided with a toe-clamp of novel construction and operation. This toe-clamp comprises a bifurcated finger 92 having a slotted shank which is adjustably secured by screws 98 to a lever 91. This lever, as shown in Figs. 3, 4e, and 6, has an elongated opening 95 and is secured to the toe-post 65 by a screw 96 passing through the opening 95. This connection is such as to permit both pivotal and longitudinal movementsof the toe-clamp lever on the heel-post.

The movements of the toe-clamp lever are controlled by a trip lever having a hub 97 j ournaled on the screw 96 outside of'the toe clamp lever. The toe-clamp lever is provided at its lower end, with a sleeve 98 in which is a coiled compression spring 99 engaging the hub 97 of the trip lever. This spring tends constantly to pull the toeclamp lever downward until the upper end of the opening 95 engages the screw 96.

In the inoperative position of the machine the toe-clamp is held in raised position against the action of the spring 99 by means of a cam projection 101 on the trip lever. This camengages a lug 102 on the toe-clamp lever, as shown in Fig. 4e, and thus holds the lever in raised position with the finger 92 in the position shown in Fig. 4. T/Vhen the lasted shoe has been placed upon the jack by the operator, the operator pulls forward an arm 103 constituting part of the trip-lever, thus rocking the cam 101, and the toe-clamp lever rocks with the trip-lever until the finger 92 extends over i clamp reaches this position, the swinging' movement of the toe-clamp lever is arrested by means of an adjustable stop-screw 107 which is threaded in the lug 102 and which engages a lug 108 on the-toe-p'ost. The continued forward movement of the arm 103 then rocks the cam 101 out of engagement with the lug 102, whereupon the spring 99 pulls the toeelamp lever and the toeclamp downward, thus causing the finger 92 to press downward upon the sole.

With the parts in the position just described, the machine is thrown into operation and the jack and the form swing rearwardly into operative position. The engagement of the work occurs first at the heel portion of the sole, and the pressure is then transferred by a continued rolling motion toward the toe of the sole. As soon as the heel portion, has been disengaged by the form, the heel clamp 89 moves into engagement with the heel-end of the sole. As the form approaches the toe-end of the sole, it is necessary to remove the toe-clamp therefrom, and this operation is performed automatically. A tripfinger 109, shown in Figs. 1, 2 and 7, is fixed adjustably by means of a set screw 111 in a lug 112 mounted at the inside of one of the uprights constituting a portion of the frame 18 of the machine. As thejack swings rearwardly, this trip-finger engages an arm 113, which constitutes a portion of the trip-lever and projects upwardly from the hub 97 in the position shown in Figs. 1 and 2. By the engagement of these parts the arm 113 is swung forward during the continuedmovement of the ack, thereby bringing the cam 101 again into engagement with the lug 102 on the toe-clamp lever. The toe-clamp lever is thus swung forwardly so as to disengage the finger 92 from the sole, and when it has swung to the position of Fig. 4-, a stop-screw 10-1 on the lever engages a lug on the toe-post. The swinging movement is thus, arrested and the continued movement of the cam 101 causes the lug 102 to ride upon the cam, thus raising the toeclamp lever into its inoperative position as in Fig. 4.

The movements of the trip-lever are limited in both directions by means of a stop 106 fixed to the toe post and engaged alternately by the arm 103 and the cam 101.

During the forward or return movement of the aclr the pressure of the form is transferred progressively from the toe to the heel of the sole. The rocking movements are repeated until the operator depresses the treadle to set in operation the second or companion mechanism, when the first set of d vices comes to rest with the parts in their forward position of presentation, and with the toe-clamp ready to be moved into ongagement with the next sole by the operation of the arm 103.
