SHOE-TURNING MACHINE.

SPECIFICATION forming part of Letters Patent No. 594,810, dated November 30, 1897.

Application filed February 19, 1897- Serial No. 624,211. (No model.)

To all whom it may concern:

Be it known that I, GEORGE H. RYAN, acitizen of the United States, residing at Brockton, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Shoe-Turning Machines; 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.

This invention relates to improvements in shoe-turnin g machines, and particularly to improvements in machines for turning the counter or back part of a turn-shoe,in the manufacture of which shoe the upper and sole are united and the shoe practically made up inside out and turned right side out after it is completed.

The invention relates more especially to improvements in the machine for which Letters Patent of the United States, numbered 460,526,and dated September 29, 1891, were issued to Jason H. Edgerly, of Chicago, Illinois.

The invention has for its objects to improve the construction of the machine and thereby increase the ease of operation, increase its practicability, and lessen the room required for its operation.

With these objects in view the invention is carried out substantially as illustrated on the accompanying drawings,which form an essential part of this specification, and whereon Figure 1 represents a plan View of the machine. Fig. 2 represents a side elevation. Fig. 3 represents a central vertical section of the same. Fig. 4 represents a front elevation of the top part of the machine.

Similar characters of reference refer to similar parts on the different parts of the drawings.

The machine is provided with a suitable standard or support 1 for the support of its various parts, which standard is preferably made circularand hollow, as shown. The head 2 has a portion 3 fitting within the circular upper end of the standard, to which it is firmly secured by means of the set-screw 4. The head 2 is also provided with the horizontal portion 5, made in one piece with the head or secured thereto by means of the screw 6 and having guideways 7 7, one of which is dovetailed, as shown in Fig. 4, and within which the form over which the back or counter part of the shoe is to be turned is held. This form consists of the plate 8, which fits in the guideways 7, properly adjustable forward and backward in said guideways, and firmly secured in its adjustable position by means of the thumb-screw 9, substantially as shown. It also consists of the form proper attached to or made in one piece with the plate 8, having side walls 10 1O projecting vertically from the plate, and a rear wall 11 projecting upward and slanting backward from'said plate, and an open front through which the forward part of the shoe projects while being turned, the top or plan view of said form being substantially that of the rear part of the sole of a shoe to be turned and substantially as illustrated on the drawings. Several of these forms are to be supplied with each machine, differing in form and size in accordance with the form and size of the different shoes to be turned on the machine.

To the lower part of the standard 1 or a bracket 12, attached thereto and preferably at the rear of said standard, is pivotally secured the treadle 13, which preferably projects through slots 14.14 in said standard toward the front of the machine and sufficient to be within easy reach of the operator. Midway the height of the standard, to cars made in one piece therewith or to a bracket 15, attached thereto, is pivotally attached the link 16, the forward end of which is pivotally attached to the upper end of a rod 17, which in turn is pivoted at its lower end to the treadle, as shown. To the link 16 is secured one end of the spring 18, the opposite end of which is secured to the head 2, substantially as shown. The tendency of the spring 18 is to draw the treadle upward with a yielding pull, thus causing the treadle to be normally at its upper position. To the forward end of the link 16 is also pivotally attached the lower end of a second rod 19, the upper end of which is pivoted to the lower end of the curved lever 20, fulcrumed at 21 to the horizontal portion 5 of the head and having its upper end turned downward, so as to be norinally above the form over which the shoe is to be turned. The lever 20 is socketed, as shown at 22, split, and provided with ears through which the screw 23 is screwed for a-purpose as will be described hereinafter. \Vithin the socket 22 is inserted the plunger 24;, which plunger is movable in and out within said socket to properly adjust the length of the plunger,which afterbeing so adjustedis firmly clamped and held in position by the screw 23, as will be readily understood by reference to the drawings. The plunger is provided with a flat surface on its lower end and made easily removable from the socket in the lever 20, so as to be replaced by plungers having different sizes and shapes of flat lower ends to adapt the plunger to the size and shape ofv shoe to be turned and the corresponding form 10 11 used upon the head over which the shoe is to be turned.

The operation of turning the back or counter part of a turn-shoe on myim proved machine is similar to that of the machine described in the patent to Jason l-I. Edgerly, above referred to, and is as follows: After the sole and upper of the turn-shoe have been united or sewed together in a suitable machine for that purpose and is inside out, it is placed upon the form in the head 2, as illustrated on the drawings. The operator then depresses the treadle 13 against the influence of the spring 18, causing the link 1 6 to turn on its bearing in the bracket 15 and the lever 20 on its fulcrum 21, and thereby forcing the plunger 24, attached to the end of said lever, forward and downward in a curved line against the lower part of the counter, where it joins the sole of the shoe which is held on the form by the operator. As the plunger is caused to descend farther into the hollow form, carrying with it the sole of the shoe, the operator gradually allows the upper to be drawn over the rounded edge of the walls of the form and into the hollow part of the form. Thus it will be seen that the back or counter part of the shoe is turned right side out, leaving the fore part of the shoe still remaining inside out, which is then placed upon another machine especially designed to turn the fore part of the shoe; but if so desired the fore part of the shoe may be turned prior to placing it upon my improved back or counter part turning machine.

I-Ieretofore in machines of this class it has been customary to make the form over which the shoe is turned with vertical walls only and to have the plunger move in a straight line vertically into and out of the form When machines of this construction have been used, it has been found by experience that on account of the inward curve from the sole toward the top of the upper of the back part of the shoe the shoe could not be placed upon the form in propel-position to be forced downward into the form, as the sole would naturally project slightly over the back wall of the form and when pressed downward was very liable to be crippled or bent from its proper shape.

By the use of my improved form, having its back wall inclined backward, the shoe can always be placed in such a position that the upper edge of the walls of the form will come at the junction of the edge of the sole with the upper, and by having the plunger mounted upon a lever pivoted to the machine in a position substantially as illustrated on the drawings said plunger moves in a curved line and draws the upper over the top edge of the walls of the form with an easy or rolling motion, said motion being abrupt and liable to injure theshoe when a plunger moved vertically is used.

By dividing the connecting-rod, which is between the treadle l3 and the lever 20, into two parts, as 17 and 19, pivoting said parts together and attaching one end of the link 16 at or near the pivoted connection between said parts and attaching the other end of the link to the standard and pivoting the lever 20 to the head, all substantially in the relative positions shown on the drawings, it will be seen that a'given movement imparted to the treadle will cause a much greater movement of the plunger 24. This increase in the movement of the plunger over the movements of the treadle is caused from the fact that as the treadle is depressed the pivotal connec tions between the treadle and the rod 17 and between said rod and the link 16 both move forward or in the same direction and move substantially equal distances, while the pivoted connections between the link 16 and the rod 19 and between said rod and the lever 20 move in opposite directions, the first-named connection moving forward and the latter moving backward,and as the rod 191s the same length in whatever position it may occupy it will cause the pivotal connection between said rod and the lever 20 to move an increased distance over the pivotal connection between said rod and the link 16, and as the rod 19 is connected to the short arm of the lever 20 and the plunger 24 to the long arm of said lever it will be seen that said plunger must of necessity be moved a greater distance than would be imparted to said plunger if the treadle and the lever 20 were joined by a single rod, as is usual in such cases. This increase of movement of the plunger carries the same upward and backward out of the way of the form which receives the shoe and therefore increases the room for the operator in which to work while placing the shoe upon the form or removing it therefrom without the necessity of increasing the movement of the treadle to accomplish the same result.

Having thus fully described the nature, construction, and operation of my invention, I wish to secure by Letters Patent and claim- 1. In a machine for turning the rear or counter portion of a turn-shoe, a form over IIO which the shoe is turned having an open front,

Vertical side walls, and outwardly-slanting rear wall, whereby the shoe may be placed upon said form with the walls of the form directly under the junction of the edge of the sole with the upper, for the purpose set forth.

2. In a machine for turning the rear or counter portion of a turn-shoe, the combination with a form over which the shoe is to be turned, having an open front, vertical side Walls and outwardly-slanting rear walls, of a lever pivoted to the frame, a plunger mounted on the lever, a treadle, and connected mechanism between said treadle and lever moving said plunger in a curved line into and out of the form, for the purpose set forth.

3. In a machine for turning the rear or counter portion of a turned shoe, a treadle,

a form over which the shoe is turned, a lever fulcrumed to the machine, a plunger attached to said lever, and connected operating meeh-.

end to the frame of the machine and at the other end to the pivotal joint between said rods, for the purpose set forth.

In testimony whereof I have affixed my signature in the presence of two subscribing wit- 0 GEORGE H. RYAN.

In presence of- ISAAC W. SKINNER, Row. M. FULLERTON.
