SOLE-LAYING MACHINE.

SPECIFICATION forming part of Letters Patent No. 553,948, dated February 4, 1896.

Application filed November 21, 1894:. Serial No. 529,497. (No model.)

To all whom it may concern:

Be it known that I, ERASTUS E. WINKLEY, a citizen of the United States, and a resident of Lynn, in the county of Essex and Commonwealth of Massachusetts, have invented a-new and useful Improvement in Sole-Laying Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

1o My invention relates to improvements in machines of the above class; and it consists of improvements in the form and arrangement of mechanism hereinafter more specifically set forth and claimed.

I5 The object of the present invention is to produce a simple and effective machine for laying shoe-soles embodying a plurality of jacks without the expensive duplication of v mechanism heretofore found in machines of this class.

My invention is illustrated by the drawings herewith submitted, in which Figure 1 is a side View of a machine embodying the same. Fig. 2 is a front view. 2 5 Fig. 3 is a detached view of jack,showin g same in position for removal of last therefrom. Fig. 4 is a top view of the form-carrier and pressing-form. Fig. 5 is a detached view of portion of stopping and starting mechanism. Fig. 6 is a section on line XX, Fig. 4:. Fig. 7 is a side view of form and carrier.

Similar letters and figures of reference refer to similar parts throughout the several Views.

In the drawings, A represents a frame suit- 3 5 able to support the working parts of the machine and which is preferably in the form of a central standard or upright 1, and a horizontally and downwardly ext-ending arm 2, mounted upon a suitable base, which arrangement provides support for the working parts hereinafter described and is out of the way of the operator.

Mounted in the frame A is a shaft 3, which I is preferably provided with a long bearing 4:, 5 in the standard 1, in which it is free to rotate and which sustains the shaft 3 and parts mounted thereon. The shaft 3 projects through the bearing a toward the front of the machine, and upon it is mounted a vertical frame l3,which carries the jacks and forms and is splined or otherwise rigidly secured to the shaft 3,s0 as to rotate therewith. From the frame 13 projects a series of radial arms D D D, 850., each of which conveniently consists of the four parallel rods 6 6 6 6, suitably 5 5 secured to the central portion of the frame B. Mounted upon each of the arms D D D, &c., is a form-carrier 7, which is provided with suitable bearings for the rods 6 6 6 6, alongwhichitisfree toreciprocate. As shown in the drawings, the form-carrier 7 consists of an upper plate or frame,8, and alower plate or frame, 9, and suitable connections between the same, but any device which will suitably support the pressing-forms may be substituted therefor.

Carried by each of the carriers 7 is a pressing-form F. The form F forms no part of the present invention and may be of any suitable construction. As shown in the drawings, it consists of a series of strips 10 1O 10, &c., of green hide or other suitable flexible material, secured at each end in the holders 11 11, each of which is pivotally mounted upon a rod 12, which extends through suitable bearings in the form-carrier 7, in which it is free to reciprocate. The inward motion of each of the rods 12 is limited by a shoulder 13, which bears against the lower plate or frame 9. Around each of the rods 12 is a coiled spring 14, which bears against the plate 8 and the shoulder 13. The above-described arrangement is such that each of the flexible strips 10, which together form the pressing-form F, is supported at each end upon a pivoted independent elastic support, which enables the form F to adapt itself to any-shaped last.

It will be noted that in the form F there are no rigid lateral supports, but the strips 10 are supported only at the ends, leaving the ceno tral portion free to conform to the curvature of the sole.

I wish to say that the feature of pivoting the holder 11 to rod 12 may be dispensed with and same rigidly secured thereto and the same result secured if strips 10 10 are not too wide.

It will be noted that supporting each end of strip 10 independently upon an elastic support has a tendency to equalize the pressure on all parts of the sole, since it enables one end of the strip to fall below the other and allow the strip to adjust itself to the lateral contour of a last having one side higher than the other, as is the ease in many styles of last,

especially between the ball and shank. Between the rods 6 (5 [3 (5 under the forms F F F, i &c., are mounted the jacks 5 5 5, &c., upon the central portion of the frame B.

Each of the jacks consists of a toe-rest and heel support 16 provided with the usual l spindle (not shown) adapted to be inserted in l the spindle-hole of the last. The heel-support is adjustable toward and away from the toe-rest to adapt the jack for different sizes of shoes. A mechanism may be conveniently l provided for locking the last in the jack, several forms of which are well known in the art 1 and the description thereof is regarded as unl necessary herein.

I find it convenient for the removal of a shoe from the jack and the adjustment of a shoe in the jack to mount the jack 5 on the standards 17 and 18, the standard 18 being pivoted to frame B and the standard 17 resting thereon. This enables the jack to be swung out from under the form in front of the machine for the removal or adjustment of a shoe. The standard 13 may be conveniently provided with a shoulder 19, which comes in contact with frame B and limits the outward motion of the jack 5. The planes in which the jacks 5 5 5, &c., tip as above set forth are substantially at right angles with the plane of rotation of frame B.

I secure the pressure of the forms upon the jacks as follows: To each of the form-carriers 7 7 7, &c., is secured a series of coiled springs 20 2O 2O 20. which are also secured to the frame B. The springs 20 2O 20 20 act to force the form F down 011 to the sole of a shoe upon the jack 5 with sufficient pressure to bring the sole into conformity with the bottom of the last therein. The springs 20 20, &c., as shown, act as tension-springs, but by arranging them above the carrier 7 they can readily be changed to compression-springs without any departure from the essential nature of my invention.

I secure the motion of clearance by the following mechanism: At each end of the formcarrier 7 projects a cam-roll 21, between the rods 6 6, which as the frame B rotates engages with a stationary camway 22 secured to and supported by the frame A, one of the camways 22 being conveniently secured to the standard 1 and the other to the arm 2. hen the cam-rolls 21 21 enter the camways 22 22, being carried along in the same by the rotation of the frame B, they first raise the form 13 to the point of greatest clearance, which is the highest point on the cam-paths 22 22, and then allow it to be lowered again by springs 20 20 until brought down onto the jack with the full tension.

By means of a stop mechanism, a convenient form of which I will presently describe, the rotation of the frame B is stopped when the form F is in a position of clearance, so that l the jack may be removed from under same. 1

The shaft 3 is rotated by means of a gear 30, which engages with pinion 31 on a shaft 32, mounted in suitable bearings in the frame A. The shaft 32 is rotated by means of a pulley 33. The pulley33 is mounted upon a sleeve 34, which turns loose upon the shaft On the shaft 32 is a sleeve 35 splined or otherwise rigidly secured to the shaft In the sleeve 34 are a series of projecting spindles 36 36 adapted to engage with circular slots t not shown) in sleeve 35, and lock the sleeves so that they will rotate together. I have not illustrated this arrangement in detail, as the same constitutes a clutch well known in the arts and of which no description is necessary to enable a person skilled in the art to construct same. The clutch is held in engagement by a spring 37.

Below the sleeve 34 is mounted a swinging fork 38, which embraces the sleeve and carries the inwardly-projecting pins 39 39, which engage in a groove 40 in the sleeve 34. The arrangement is such that when the fork 38 is vertical the pins 39 39 are in the horizontal plane of the axis of the shaft, or substantially so, and when the fork 38 is swung to and fro with the sleeve 34, as hereinafter described, the motion is so slight that the pins 39 39 will not be thrown out of engagement with the groove 40. One of the pins 39 extends through its bearing in the fork 3S and is pivoted to a guide-bar 40, secured in suitable ways 41, in the lever 42, in which it is free to slide. The lever 42 is pivotally connected to the treadle 43, fulcrumed on frame A, the arrangement being such that the lever 42 may be raised by the treadle 43 (a suitable spring or the weight of the treadlc restoring it to its original position after being raised by treadle) and is free to swing upon its pivotal connection with the treadle carrying the sleeve 34 along the shaft 32.

Upon the gear 30 are a series of inclined or wedge-shaped dogs 45 45 45, 830., which as the gear 30 rotates are adapted to come in contact with the lever 42, or the projection 46 therefrom,when the lever 42 is in its normal position, the result being that the lever 42 is swung backward upon it,bearing upon treadle 43 by the action of the inclined face of the dog 45, carrying with it the swinging fork 3S and sliding the sleeve 34 along the shaft 32 and disengaging same from sleeve 35 and stopping the rotation of shaft 32 by pulley 33.

The dogs 45 45, &c., are so placed upon the gear 30 that the stopping of the rotation of shaft 32 above described occurs when the cam-rolls 21 21 are in such position on the cam-paths 22 22 that the form is in a position of clearance.

it will be noted that there is a dog 45 for each of the arms D D, &c., upon the frame B.

\Vhen it is desired to again start the rotation of shaft 32, the lever 42 is raised by the treadle 43 until the projection 46 clears the dog 45, which leaves the lever 42 and fork 38 free to swing forward, the spring 37 acting to move the sleeve 34 along the shaft 32 and engage the same with the sleeve 35.

The operation of my invention is as follows: The operator standing in front of the machine, power being applied to pulley 33, tips out one of the jacks 5 and adjusts thereon a lasted upper. He then places the pasted outer sole in position thereon, tips the jack 5 back to a vertical position under its form F, and by a downward pressure of the treadle 43 sets the frame B in rotation, which carries the camrolls 21 21 along the camways 22 and allows the springs 20 2O 2O 20 to bring the form F down onto the pasted outer sole and to exert their tension (or compression) to firmly press the sole on to the upper and bring it into approximate conformity with the bottom of the last. As already stated when brought down upon the sole the flexible strips 10 1O 10, being independently supported at each end, readily adapt themselves to the shape of the bottom of the last and exert an even pressure on all portions of the sole, whatever the size or style. The frame B continues its rotation until the form upon the next arm D is brought into a position of clearance,when its rotation ceases, and the operator tips out the jack 5 thereon and removes the finished work there from and adjusts another upper and sole. It will be readily seen that by this arrangement I secure all the advantages of a plurality of jacks, upon each of which the work can remain under pressure while the Work on the others is being removed and other work adjusted, without multiplying expensive toggle mechanisms or other devices by which pressure has heretofore been secured-in machines of this class.

Having thus fully described my invention and the mode of its operation, I wish to say that I do not consider my invention limited to the details of construction herein shown and described, but I claim as novel and desire to secure by Letters Patent 1. In a sole-laying machine the combination, with a suitable support therefor, of a rotating frame, a series of shoe-supporting jacks mounted upon said frame, a series of movable pressing-forms also mounted upon said frame, a series of springs, acting upon the pressing-forms and connected with a fixed portion of the frame, for bringing each form in contact with a last placed upon its associated jack, camways secured to said support, and cam-rolls connected with said pressingforms acting with the camways to bring each form into a position of clearance,substantially as described.

2. In a sole-laying machine the combination, with a suitable support therefor, of a rotating frame, a series of shoe-supporting jacks mounted upon said frame, a series of movable pressing-forms also mounted upon said frame, a series of springs arranged to bring each form in contact with a last placed upon its associated jack, and mechanism common to all the forms for raising each form independently into a position of clearance, substantially as described.
