To all whom it may concern:

Be it known that I, WARREN R. Goonwnv, ot Stonehani, in the county of MiddleseX and State of Massachusetts, have invented certain new and useful Improvements in Sole-Laying Machines, of which the following is aspecification.

This invention relates to machines for pressing cement-coated outer soles against lasted I I0 uppers of boots or shoes and holding said The same letters of reference indicate the same parts in all the figures.

In the drawings, a represents the supporting-frame, having vertical tubular sockets or guides b b, in which are fitted to slide the rods or standards 0 0. On the upper ends of said rods are the sole supporting and molding pads d d, which in the present instance are two in number, one formed to support and mold the heel and shank and the other the fore part. Each pad is composed of rubber and rests on a metal plate, 6. The plates 0 e have semicircular bosses ff on their under sides, fitting corresponding sockets g g, secured to the upper ends of the standards 0 c, the pads being thus adapted to assume various inclinations. If

desired, however, a single pad, (I, may be employed, instead of the two pads, said single pad being supported by the two standards 0 c, as shown in Fig. 3.

The standards 0 o are supported by a rocking lever, h, pivoted to a central standard, I, which is fitted to'slide in a guide or socket in the frame a, and rests at its lower end'on a lever, j, which is pivoted at k to the frame a. The

lever j rests on a foot-lever, Z, and is raised with Fig. 3 reprethe standard 13 by the depression of the outer V end of said lever Z by the operators foot.

It will be seen that the raising of the standard 1' causes the roekin g lever h,pivoted thereto, to raise the standards 0 c and the sole-pressing pad or pads. It will also be seen that the pivotalconnection of the rocking lever h to the standard i enables said crosshead to oscillate andassume any desired angle, thus permitting any desired inclination of the pad or pads cl and enabling said pad or pads to conform to last-bottoms of different shapes. The operator raises the sole-pressing pad or pads in the man ner described sufticiently to bring the sole laid on said pad or pads into contact with the bottom of the upper on the last, which is held by the devices hereinafter described. I .When the operator releases the foot-lever Z, after raising the pads, the standard i is automatically locked in its raised position by two locking-jaws, n it, formed to bear against opposite sides of the standard 1' and held thereagainst by two links or levers, 0 0, pivoted at their outer ends to the frame a and bearing at their inner ends against rods 1) p, which are interposed between said inner ends and the outer sides of the jaws n n. The pivots of the links 0 0 are lower than the bearing-points of their inner ends, so that when the standard 1' is raised the links and jaws yield and offer no resistance to the upward movement of the standard; but when the foot-lever is released the inner ends of the links immediately press the jaws n n with sufficient force against the standard i to hold it and the devices supported thereby in the position to which they were elevated by the foot-lever.

' The rods 1) p project outwardly from the jaws a a, through slots 1 in the frame a, and bear upon one arm of an angular lever, I, which is pivoted at s to the frame a. When the operator desiresto depress the pad or pads d, he IllOVEStllG lever 7' so that its lower arm raises the rods 1) p and jaws n It, thus releasing the standard 6, whereupon said standard, the pads, and the intermediate devices fall by their own weight.

enter the socket in the rear portion of the last and the other to bear upon the fore part of the last. Said standards are secured to a crosshead, a, which is attached to a vertical rod or slide, 1), fitted to slide in a socket, w, on the upper part of the frame a.

areprcsents a lever pivoted at b to the frame a and atc to the jack-supporting slide 1). The opposite end of said lever is connected by a rod, (1, with an eccentric, c, on a shaft, f which is geared to a driving'shaft, g. The retation of the shaft f and the eccentric thereon causes the lever a to oscillate, and thus alternately raise and depress the jack, consisting of the crosshead a and standards i 1 and the last supported by said jack.

The driving-shaft has a pulley, i, on which the driving belt runs. Said pulley is adapted to be made loose on the shaft and is engaged with the shaft by suitable devices, so that when the eccentric c is in its highest position and has depressed the last to the lowest point the rotation of the drivingshaft may be stopped by the automatic disengagement of the pulley i from it and the eccentric held in the position last described to maintain the pressure on the last and the sole held between it and the pad or pads at until the cement has sufficiently set or hardened, when, by a movement of a suitable foot-lever, j, the pulley may be again engaged with the driving-shaft and the latter rotated until the eccentric reaches its lowest point, where it may be again automaticallyarrested until the operator has had time to remove the last and the cemented sole and upper thereon and apply another last and place another sole on the pad or pads.

In Fig. 6 Ihave shown ascction on the line 2, Fig. 2, looking toward the pulley i. As shown in said figure, the hub of said pulley has a series of internal teeth, 7:, while to the shaft 9 is affixed a collar, m, having pivoted to it a pawl, 0, adapted to engage the teeth 7 and held in engagement therewith by a spring, 1), acting on a lever, q, affixed to the pivot of the pawl 0.

1' represents an arm which is attached to the foot-lever j, and is so arranged that when said lever is in its normal position it (the arm 1-) will stand outside of the path in which the lever q travels, as shown in Fig. 4; but when the foot-lever j is moved by the operators foot the arm 1" swings into position to collide with the lever and disengage the pawl o from the hub of the pulley.

The operation of the machine is as follows: The jack being raised and the pad or pads d depressed, the operator applies a last having an upper to the jack, and places a cementeoated solo on the pad or pads (1. He then, by depressing the fo0t-lever Z, raises the pads and causes the sole thereon to bear on the bottom of the upper. Thejaws n a hold the pads and sole at the point to which they are thus elevated, as above described. The drivingshaft is then set in motion and the eeeentrice raised, causing the depression of the last and the upper thereon, and pressing the sole and upper firmly together, the last being held depressed, as above described, until the cement has hardened.

My invention is not limited to the details of construction herein described, and the same may be varied in several particulars. For example, one of the locking-jaws a may be Iiaed instead of being on the movable end of a l1nk or lever, or only one jaw may be employed, one side of the guide or socket in which the standard 77 slides being the equivalent ofa fixed jaw.

The power-driven mechanism which raises and depresses the jack: may be stopped by devices which are not automatic, instead of by the automatic means herein described.

The foot-lever I, which raises the standard 17, may act directly on said standard instead of acting through the intermediate lever, j.

I claim 1. In a sole-laying machine, the combination, herein described, with suitable last-supporting devices, of a sole-pressing pad or pads, two verticallyanovable standards supporting the same, a rockingleversupportin g said standards, a supporting-standard for said rocking lever, and a foot-lever whereby said standards may be raised simultaneously, the rocking lever enabling the pad or pads to con form to the inclination of the bottom of the last, as set forth.

2. In a sole-laying machine, the combination, herein dcscribcd,ofsuitable last-supporting dcvices,a sole pressin g pad or pads, a verticallyanovable standard supporting said pad or pads, a foot-lever adapted to raise said standard and pad or pads, and automatic locking devices, substantially as described, whereby the standard is locked at any point to which it may be raised, as set forth.

- 3. In a sole-laying machine, the combination, herein described, ofsuitable last-supporting devices, a sole-pressing pad or pads, a vertically-movable standard supporting said pad or pads, a foot-lever adapted to raise said stand ard and pad or pads, automatic locking devices, substantially as described, whereby the standard is locked at any point to which it may be raised, and means whereby the standard may be released to permit the gravitating movement of the standard and the pad or pads supported thereby, as set forth.

4. The combination, with the pad-supporting standard and devices, substantially as described, for raising the same, of the jaws hearing against opposite sides of said standard,and the links pivoted at their outer ends to the supporting-frame and engaged at their inner ends with said jaws, as set forth.

5. The combination, with the pad-supporting standard and devices for raising the same, of the jaws, the pivoted links arranged and engaged with the jaws, as described, the rods or pins projecting from said jaws, and the angular pivoted lever arranged to bear against said pins and raise the jaws, as set forth.
