SHOE-SUPPORT FOR SOLE-LEVELING MACHINES.

To all whom it may concern:

Be it known that I, ERASTUS E. VVINKLEY, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Shoe-Supports for Sole-Leveling 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.

The present invention relates generally to improvements in shoe supports for leveling machines, and more particularly to improvements in shoe supports for leveling machines of the vibrating roll type.

Sole leveling machines of the vibrating roll type, such for example as the machine of Letters Patent No. 555,548, issued to me March 3, 1896, are commonly used only for leveling welted boots or shoes which are leveled upon the last upon which the shoes are lasted, it being heretofore the practice to level shoes, from which the last had to be removed to attach the sole, and which were not leveled on the original last, but on a follower, so called, upon the several types of rolling pressure and direct pressure leveling machines. This limited use of the vibrating roll leveling machine is largely due to the fact that when a second last or follower has to be inserted in a shoe, it never fits as tightly as does the original last upon which the shoe was lasted, and the shoe is therefore liable to be more or less displaced thereon by the action of the leveling roll on its sole so that the leveling operation is imperfectly performed.

The object of the present invention is to provide a shoe support for sole leveling machines of vibrating roll type whereby such machines may be enabled to successfully level boots and shoes from which the original last has been removed. My invention, however, as to some of its novel features has for its object to improve the shoe supporting devices of this class of machines generally Whether the shoe is to be leveled on its original last or not.

To the above ends the present invention consists ofthe provision in a shoe support for sole leveling machines of a novel clamping means whereby the shoe may be clamped on its follower, and held from slipping under the action of the roll to interferewith the successful operation of the machine, the

present invention further consisting of other improvements in the construction and organization of devices of this class which are clearly pointed out in the claims and which secure advantages which will be obvious. to one skilled in the art from the following description:

The preferred form of the present invention is illustrated in the accompanying drawings in which- Figure 1 is a side elevation of a shoe support embodying the same, Fig. 2 is an end elevation of the heel post removed, and Fig. 3 is a plan of heel support after removal of the heel post.

Referring to the drawings A represents the body of the device, and B the toe support which may be and conveniently are substantially like corresponding parts of the jack shown and described in U. S. Letters Patent No. 580,746 issued to me April 13, 1897, the body A being provided with a raised guide-way a substantially as therein shown and described.

Mounted to slide on the guide-way a is the base 1 of the heel support. Suitable clamping means (not shown) are provided, which may be and conveniently are substantially like that shown in said patent whereby the base 1 may be clamped in any desired position along the guide-way a to adjust the shoe support for shoes of different lengths.

Upon the base 1 is mounted the heel post carrier 2, which as shown consists of a circular base (E, from the top of which is projected a lug 5 The heel post carrier is rotatably mounted on the base 1, a circular guide-way being provided thereon to which the circular base a of the heel post carrier is fitted, and in which it is free to turn. As shown the circular guide-way above referred to is formed by two semi-circular gibs a, and 7), secured by the bolts 0 to the base 1. It will be noted in this connection that by removing either of the bolts 0 in the gib b, the circular guide-way may be opened and the heel post carrier 2 removed. This arrangement enables the entire heel support to be removed from its base, and a different form of heel support substituted therefor to equip the jack for a different class of work. Upon the heel post carrier 2 is mounted the heel post 3, which is arranged to tip thereon toward and from the toe support B. As shown the heel post 3 has a bifurcated lower end a which embraces the lug b on the heel post carrier 2, and which is provided with bearings 5 for a pin 0 supported by the lug Z9 By the arrangement hereinbefore described the jack post 3 is rotatable with its carrier 2 and free to tip toward and from the jack post B independently thereof. The heel post 3 is provided with suitable means for holding the follower, conveniently the spindles (i which extend into suitable holes in the follower. I prefer to use two spindles because the follower is thereby prevented fro-1n turning on the heel support.

While I do not consider the specific con-- struction of the follower as an essential feature of the present invention considered broadly, I prefer to use substantially the construction shown in the drawings because it enables the clamp to be readily inserted in the back of the shoe and I find that when the clamp is applied to the heel portion and tends to pull the shoe onto the follower, it acts most effectively to hold the shoe in position although the clamp may be otherwise located without departure from my inven tion.

In the drawings 4 represents the follower, which may be of wood or iron, and, which as shown is shaped like alast with the back of the heel cut away so that the clamp hereinafter described may be inserted in the shoe back of the follower and engage the heel portion thereof.

I desire to say that the term follower as herein used, unless otherwise limited, includes any device of wood, iron or other material designed to be inserted in a shoe and to support the sole thereof during the leveling operation.

The clamp which holds the shoe on its follower is shown at 5 and as shown has the general shape of the'back of the heel of a last so that when the clamp is closed and in contact with the back of the follower 4 a substantially complete last is formed. The form and arrangement of the clamp 5 and of its actuating mechanism hereinafter described may be varied without departing from the spirit of the present invention. In the form of my invention shown in the drawings the follower is clamped between the toe support B and the heel support by tipping the heel support toward the toe support and as therein shown the same mechanism which actuates the clamp 5 also actuates the heel post 3 to clamp the follower as above stated.

As shown the clamp 5 comprises a bent lever, pivoted at its angle to the heel post 3 and having an arm a projected into an aperture in said post. Above the arm a is a spring 6 which bears against said arm and a fixed portion of said post. Bearing against the under side of said arm a is a sliding rod 6, free to slide in suitable bearings in the post 3, and the lower end of which rests upon a cam a rigidly secured to a short shaft 12, free to rotate in suitable hearings in the lugsd, e, on the base 1 of the heel support. The shaft 79 may be rotated by a hand wheel 0 The above described arrangement is such that a rotation of the hand wheel 0 in one direction tends to raise the rod 6 and to tip thepost 3 toward the toe support 13, and when the toe of the follower 4 is pressed firml against itsrest a further rotation of the wheel 0 tends to raise the arm 64 against the tension of the spring .72 and move the clamp 5 away from the follower 4 thereby causing it to draw the shoe firmly onto the same and to hold it from slipping thereon. When the wheel 0 is turned in an opposite direction the cam a permits the rod 6 to drop and the spring 6 closes the clamp 5 bringing it into contact with the back of the follower 4.

I11 using my improved shoe supporting device, the operator turns the follower 4 with the heel support 3 until it is in a convenient position for insertion in a shoe.

The shoe is then drawn over the follower' and down over the clamp 5, which is then closed and in contact with the back of the follower. The follower is then turned with the heel support until its toe is over the toe rest, and by turning the wheel 0 the operator tips the heel support to clamp the follower between it and the toe support and at inbefore described, but claim as new and wish to secure by Letters Patent:

1. A shoe support for sole leveling machines, having, in combination, a follower, toe and heel supports therefor mounted to have a relative tipping movement to clamp the follower between them, a clamp on the heel support arranged to enter the shoe to clamp it on the follower, and means for relatively actuating the supports and clamp, substantially as described.

2. A shoe support for sole leveling machines, having, in combination, a follower, toe and heel supports therefor having a relative tipping movement to clamp the follower between them, a clamp on the heel support arranged to enter the shoe to clamp it on the follower, and a common actuating mechanism for relatively actuating the toe and heel supports and actuating said clamp, substantially as described.

3. A shoe support for sole leveling ma- 10 for locking said supports Copies of this patent may be obtained for movement and means to simultaneously contract said shoe support and unlock said supports to allow them to be separated, substantially as described.

In testimony whereof I aflix my signature, in presence of two witnesses.
