SOLE LAYING AND PRESSING MACHINE.

SPECIFICATION forming part of Letters Patent No. 393,216, dated November 20, 1888.

Application filed July 14, 1888. Serial No. 279,989. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK W. Gov, of Boston, in thecounty of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Sole Laying or Pressing Machines, of which the following isaspecification.

This invention relates to a sole laying or pressing machine organized substantially as shown in Letters Patent of the United States, No. 376,406, granted to me January 10, 1888. In said machine a frame carrying a series of jacks is rotated so that the jacks come successively to a given point or operators station, where each jack is released from the pressure that causes it to act on the sole, the jacks being hinged to the rotary frame, so that each jack can be swung forward when it is thus released, the forward swinging motion removing the last 011 the jack from under the molding pad or die that cooperates therewith and permitting the work to be conveniently applied and removed. A

My present invention has for its object, first, to enable the operator to notonly swing the jack out and in, as described in my former patent, but also to give the last a partial rotation when it is swung forward, so that its position may be more favorable for the operation of applying and removing the work.

The invention also has for its object to provide means whereby the operator may raise and lower the jack independently of the power-driven mechanism of the machine, so that after the work is applied to the last and before the last has been raised by the power'actuated mechanism the operator may raise it sufficiently to bring the sole to a light bearing on the pad or die, and thereby confine the sole between the last and pad, so that the sole will not be liable to he accidentally displaced while the jack is moving forward and the mechanism of the machine is raising the jack to exert the operative pressure on the sole.

To these ends the invention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents ments. Fig. 2 represents a section on line mm, Fig. 1. Fig. 3 represents a section on the same line, showing the jack partly raised by the hand-operated cam-shaft. Fig. 4 represents a perspective view of said shaft.

. The same letters of reference indicate the same parts in all the figures.

In the drawings, a represents a portion of the rotary supporting-frame, which is provided witha series of vertically-movable jacks, b, a corresponding series of sole-pressing pads or dies above the jacks, toggle-links 0, arranged to elevate and depress the jacks when forced into and out of alignment, and a fixed cam which supports said links, and is caused by the rotation of the supporting-frame to hold the links in alignment and cause them to hold the jacks in elevated positions, excepting at the operators station,where the cam is formed to permit the links to move out of alignment and thus depress the corresponding j ack. Each jack is supported by a slide, j, adapted to move in a vertical guide in the rotary frame a, the upper link, 0, of the toggle-joint being connected to said slide. The jack proper is composed of two last-supporting standards, ef, one having a spindle and the other a toe-rest for the last 9, and a lever, h, supporting said standards and pivoted at its lower end at t to the slide 3', so that the jack can either rest on the upper end of said slide and be moved upwardly thereby against the corresponding pad, or can be swung forward to remove its last from un der the pad. 7

The construction thus far described is the same as in my above-named patent, to which reference may be had for a full description of the machine and its operation.

In carrying out my invention I make the pivoted swinging lever h in two sections, 2 3, the upper one of which bears the last-supporting standards e f, and has a shank, 4, fitted to rotate in a socket, 5, in the lower section, so that when the lever h is swung forward the upper section and the last thereon may be partly rotated, as shown in dotted lines in Fig.

2, so as to cause the last to stand lengthwise with relation to the operator, and thus enable him to more conveniently apply and remove a boot or shoe than he could if the last stood sidewise, or in the position it occupies when in operation. The rotary movements of the section 3 and the last thereon are limited by.

stops k Z on the lower section and a pin, m, on the upper section playing between said stops, the arrangement being such that the upper section can have about a quarter rotation. The stop Z insures the proper position of the last when it is turned back preparatory to being raised. It is obvious, however, that any other suitable stop devices may be employed to limit the movements of the swiveled section.

To enable the operator to raise the last and thus bring the sole thereon tea light bearing on the pad before the pressing operation, I provide the slidej with a shaft, 8, having cams it, on which the upper section, 3, bears. Said shaft is journaled in bearings u a on the slide j, and is provided with a crank or lever, 11,

whereby it may be rotated. The rotation of the shaft 8 in one direction causes its cams to raise the section 3, as shown in Fig. 3, the shank 4 of said section being adapted to slide vertically in the socket of the section 2. The upward movement thus imparted to the jack causes the last to hold the sole against the pad with sufficient firmness to prevent displacement of the sole while the jack is being raised by the fixed cam and toggle-links. When the molding pressure is eompleted,the jack may be quickly depressed to free the sole from the pad by turning the shaft 8 back to the position shown in Fig. 2.

It is obvious that an iron last or form may be applied to the jack,'in which case the standards e f would not be used, but the base of the iron last or form would be swiveled to the jack.

I claim 1. In a sole-pressing machine, the combination,with the vertically-movablejack-supporting slide of a jack having its lower portion 2. In a sole-pressing machine, the combina- I tion,with the verticallymovable slidej, of the jack composed of the lower section, 2, pivoted at t to said slide, and the upper section, 3, having the last-supports and provided with the shank or pivot 4, arranged at right angles to the pivot t and swivcled in the upper end of the lower section, as set forth.

3. In a sole-pressing machine, the combination of the slide j, having the horizontal shaft 8 and cams t t, a jack composed of a lower section connected by a horizontal pivot, i, with said slide, and a vertically-movable upper section connected by a vertically-movable shank or pivot, 4,wit'h the lower section, and bearing on said cams and adapted to be supported at different heights thereby, as set forth.

Intestimony whereof I have signed my name to this specification, in the presence of two subscribing witncsses, this 2d day of July, A. D. 1888.

FREDERICK V. COY.
