SOLE-LAYING MACHINE.

SPECIFICATION forming part of'Letters Patent No. 368,131, dated August 9, 1887.

Application filed June 27, 1887. Serial No. 242,034. (No model.)

To aZZ whom it may concern.-

Be it known that we, NICHOLAS P. CLARK and HENRIE D. STONE, residents, respectively, of Lincoln, in the county of Providence and State of Rhode Island, and of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Sole-Laying Machines, of which the following is a specification.

This invention relates to machines for pressing cement coated soles of boots or shoes against lasted uppers, and for holding the soles in close contact with the uppers while the cement is setting or hardening; and it consists r 5 in the several improvements which we will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a front elevation of our improved machine.

Fig. 2 represents a vertical section on line 0002,

Fig. 1. Fig. 3 represents a bottom View,

hereinafter referred to. Figs. 4, 5, 6, and 7 represent detail sectional views, hereinafter described.

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

In the drawings, the supporting-frame is composed of a base, a, vertical uprights b b,

attached to the base, and a jack-supporting head, 0, attached to said uprights. Fitted to move between guides formed in the base a is a plunger or slide, (Z, having on its enlarged upper end a hemispherical. boss, 0.

f represents a metal bed or plate having a flat upper surface, and provided on its under side with a socket, 9, formed to fit the boss 0 and move in any direction thereon, the socket being of less depth than the height of the boss, so that when the bed fis in a horizontal position space is afforded for the downward movement of any portion of the socket on the boss. The sole pressing and molding pad 72., of rubber or other yielding material, is attached to the bed f, and is permitted by the boss and socket to tip in any desired direction, either longitudinally or laterally, and thus conform to any differences between the inclination or form of the bottoms of different lasts.

The jack which supports the last and the upper thereon is composed of two standards, 0 2' z, constructed the one to support the heel and the other the toe portion of the last. Said standards are adapted to slide on horizontal guides on the head 0, and are provided with studs 9 j, which enter cam-shaped slots is k in a disk, Z, Fig. 3, which is affixed to a vertical rod, m, journaled in a bearing in the head 0. The upper end of said rod is provided above the head cwith a handle or wheel, 12, whereby it and the disk Z may be rotated. The rotation of the disk causes the cam-shaped slots is k to move the standards simultaneously toward or from each other.

The plunger or slide (1, supporting the pad h and its universally-tipping bed, may be raised to press the sole against the lasted upper by any suitable means, and the pressure may be effected partly by the upward movement of the pad and partly by the downward movement of the jack, as in other sole-laying nia- 7o chines now in use, or wholly by the upward movement of the pad. \Ve have shown in the present case an organization whereby the p ressure is entirely effected by the upward movement of the pad. 7 5

0 represents a lever, which is pivoted at p to the base a, and at q to the slide or plunger (Z. The outer end of said lever is connected with a foot-lever, 1', which is pivoted at s to the base a. \Ve prefer to employ a stout spi- 8o ral spring, '6, as the means of connecting the lever 0 to the foot-lever 1-, for a purpose hereinafter specified, although, aside from such purpose, an ordinary connecting-rod may be substituted for the spring. The depression of the foot-lever 1 causes the elevation of the slide or plunger (1 and pad 71, and partially presses the sole on the pad against the lasted upper, the pressure thus obtained being comparatively light.

a represents a piston or standard, which is fitted to slide in a socket formed for it in the plunger or slide d.

12 represents a locking-cam, which is pivoted to the plunger (1, and is formed to permit the 5 upward movement of the plunger upon the standard a by the foot-lever r, as above described, but binds upon the standard and locks the plunger d to it when the standard is raised, so that while the depression of the foot-lever r raises the plunger independently of the standard the raising of the standard by the powerdriven devices, hereinafter described, causes the plunger to also rise. The lower end of the standard a is formed to bear on an eccentric, w, on a power-driven shaft, a. The elevation of the eccentric by the rotation of the shaft a raises the standard a and plunger d, and imparts the full and final pressure to the sole interposed between the pad and lasted upper.

, The standard and plunger are locked in the position to which they are thus raised by a locking-cam, b, pivoted to the base a, and arranged to bear on the standard and prevent its downward movement without opposing its upward movement, said cam being held in contact with the standard by a spring, 0, acting on a lever, d, attached to said cam.

We provide suitable means for automatically stopping the rotation of the shaft after each complete rotationthat is, when the eccentric, after raising the standard a and plunger d, has descended to its lowest positionand said means will be presently described.

It will be seen from the foregoing that when the operator has placed a sole on the pad h he raises the slide or plunger d, with the pad, by depressing the foot-lever r, thus. bringing the sole to a bearing on the lasted upper. The downward movement of the foot-lever is continued until said lever strikes a lever, e, which is pivoted at f to the base a and is rigidly attached to another lever, g, which normally stands in position to arrest a short arm, h, pertaining to the clutch shown in Letters Patcut to B. F. Young, dated November 2, 1875, No. 169,394. The engagement of the lever g with the arm h holds the shaft a out of engagement with its driving-pulley, while the depression of said lever g releases the short arm h and engages the driving-pulley with the shaft, as described in said Letters Patent. It will be observed, therefore, that the depression of the foot-lever r first raises the plunger d and pad hand then starts the driving-shaft, which raises the eccentric, and with it the standard it and plunger d, and gives the full pressure to the sole, the standard and plunger being automatically detained in their raised position by the cam b. the foot-lever 1' before the shaft has completed a rotation, so that the lever g is released and allowed to assume its normal position in season to arrest the arm h and disconnect the shaft or from the driving-pulley when the eccentric has reached the lowest point of its rotation. After the pressure has been applied to the sole and upper a sufficient length of time the operator turns the cam b by the lever d sufliciently to release the standard a, whereupon the standard, plunger, and pad fall until the standard bears on the depressed eccentric. The operator then, after removing the last with the upper and sole thereon from the jack and applying another last with an upper thereon to the The operator removes his foot from jack and placing another sole on the depressed pad, again depresses the foot-lever r, with the result already described.

The spiral spring t, connecting the lever o with the foot-lever r, enables said lever to be depressed after the plunger has been raised as high as it'can be by foot-power, and thus operate the clutch-releasingdevice with certainty.

Gear h is loose on shaft a, and is provided with an annular recess, h, Fig. 4, adapted to receive a block, h, therein. Said block is connected with the short arm h, by a pin, h, which passes through collar h rigidly secured to shaft a, Fig. 5. Short arm h bears against one end of the lever g, rigidly secured to one end of a short shaft, f, journaled in frame a. On the other end of shaftf is the lever 0, provided with a pin, A, passing under foot-lever r. (See Figs. 6 and 7.) v

The position of the mechanism above described for operating the machine is in its nor-. mal or inoperative position. If, now, the operator depresses foot-lever r sufficiently to engage it with pin A, the operation depresses lever e, and with it lever 9, until the end of said lever clears short arm h, when, as gearwheel h rotates to bring pocket 71. under block h, said block h will turn on its stud h so that it will engage with said pocket, and by its connection with collar it, through pin 7L7, will rotate shaft a.

When, after foot-lever 0 has been depressed and the machine started, as above explained, the pressure of the operators foot being removed, the deviees resume the position shown in the drawings by the means of springs, (not shown;) but block h will remain in its position in pocket h, last described, until one revolution of shaft a has been made, when short arm h will come in contact with the end of lever g, as shown in Fig. 7, striking the same with a yielding blow, this movement turning block h into the annular groove h and stopping the machine, as shown and described in the here inbeforamentioned patent.

We claim 1. In a sole-laying machine, the combination of a last-supporting jack, a sole-pressing pad formed to extend along the entire bottom of the sole, and a pad-support consisting of a single metal plate on which the entire length of the pad bears, a hemispherical boss, and a corresponding socket undersaidplate,whereby the latter is permitted to tip bodily in any direction, and a supporting device for said boss, as set forth.
