SOLE-LAYING MACHINE.

SPECIFICATION forming part of Letters Patent No. 315,913, dated April 1%, 1885.

Application filed September 23, 1884.

To all whom it may concern.-

Be it known that I, PETER A. Conrail, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain Im- 5 provementsinSole-Laying Machines, of which the following is a specification.

This invention relates to that class of boot or shoe sole laying machines in which the lasted upper is pressed against the outer sole while the cement applied to the proximate surfaces of the upper and sole is setting or hardening, the sole being support-ed by a sectional support which conforms to the curvature of the bottom of the last, while the last is pressed against the sole thus supported.

The invention consists in the improvements hereinafter described in the construction of the sectional support, and in the means for pressing the upper and sole against said support.

In the accompanying drawings, forming a part of this specification, Figure 1 represents a side elevation and partial section of a machine embodying my invention. Fig. 2 rep- 2 resents a section on line as :0, Fig. 1. Figs. 3 and 4 represent, respectively, bottom and top views of the sole-support. Fig. 5 represents a longitudinal section of the same. Fig. 6 represents a section on line 3 y, Fig. 3.

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

In the drawings, a represents a fixed frame having a series of vertical sockets, b b b, in which are placed sliding rods c c. Said rods have threaded stems or extensions 0, which pass through nuts (I, swivelcd in the sockets b, the rotation of said nuts raising or lowering the rods 0, according to the direction in which the nuts are rotated.

To the upper ends of the rods 0 are connected by bolts 6 a series of plates or sole-supporting sections, f, which are formed so that their upper surfaces collectively correspond to the form of the bottom of the last on which the upper g is placed. The plates f have slotted ears 2 on their lower sides, through which the bolts 6 pass, the slots j in the ears permitting any desired vertical adjustment of either rod 0. The end sections, f, each have three ears 2', two of 50 which are placed side by side and connected No model.)

to one of the rods 0. The middle section has two cars projecting from its opposite ends and connected with the single lugs projecting from the proximate ends of the end sections to the two middle rods 0. It will be seen, therefore, that the curvature of the support formed by the plates f can be raised by adjusting the rods 0, said support being thus capable of conforming to differently-shaped lasts. Each section is connected by its ears '5 to two rods 0, so that each section is prevented from tipping loosely and can only be inclined by the vertical adjustment of one or both of the rods 0, to which it is connected. I prefer to place a sheet, k,

of rubber or other yielding material on the upper surfaces of the plates or sections, said sheet extending continuously from end to end of the support, covering the spaces between the sections, and being held in place by flanges at the margins of said sections.

Z represents a jack or lever which is capable of oscillating on a bolt, on, afixed to cars on the frame a. Said jack is provided with a toe-rest, 41., adapted to bear on the toe portion of the lasted upper, and with a spindle, o, adapted to enter the spindle-socket in the last, the spindle being formed on the end of a lever,

12, which is pivoted at q to an arm, 0', projecting downwardly from the jack, and attached thereto by a bolt passing through a horizontal slot, 8, in the jack, the arm with the spindle being thus made capable of adjustment in the direction of the length of the slot 8.

The upper end of the arm 1* is provided with ratchetteeth a, with which a dog, 0, on the lever 19 engages and holds the lever in any desired position, the spindle being thus adapted to press the last forward against the toe-rest. The jack is provided with a slot, 11;, in which is a block, 42:, the pivot-bolt m passing through 0 said block. The jack is free to slide vertically on the block, and is supported bya spring, a, interposed bet-ween the block at and the upper end of the slot w. The jack can therefore be moved vertically downward against the press- 9 5 ure of the spring, and can also oscillate on the pivot m. The jack Z is extended downwardly below the pivot m, and curved forward to form an arm, 2-. Said arm is connected by a rod, b, with a treadle, e.

The operation is as follows: The sectional support being su'itably adjusted, the sole, coated on its upper surface with cement,is laid upon it, and the lasted upper is placed on the jack-spindle with its toe bearingagainst the rest a. The operator then depresses the treadle, thus causing the jack to first turn on the pivot m, and thus press the toe portion ofthe upper against the corresponding portion of the sole, and then to move bodily downward against the supporting-pressure of the spring a until the entire under surface of the upper is pressed downwardly upon the supported sole. The jack is held depressed until the cement has sufficiently hardened, when the treadle is released and the jack is raised by the spring, and raises the upper with the sole from the support.

I It will be seen that the provision of the spring a and means whereby the jack may be depressed bodily against the supportingpressure of the spring enables the upper to be pressed first against the toe and then against the rear portion of the sole. By thus applying the pressure better results are obtained than by applying it simultaneously along the entire length of the sole, because the operator can adjust the rear portion of the sole laterally after the toe of the upper strikes it, and cause it to coincide more perfectly with the bottom of the upper.

I claim- 7 1.In a sole-laying machine, the sole-support composed of sections or plates, each jointed to two independently-adjustable rods, as set forth.

2. The sole-support composed of flanged sections or plates, each jointed to two independently-adjustable rods, and provided with a continuous flexiblecovering held in place by the flanges of the plates, as set forth.

3. The combination of the rods, the sections or plates, each jointed to two of said rods, and the supporting-frame having sockets for said rods, and swiveled nuts engaged with threaded stems on the rods, as set forth.

4. The combination of the adjustable rods and the plates or sections having slotted ears, each plate being connected to two of the adjustable rods by bolts passing through the slots of its ears, as set forth.

5. In a sole-laying machine, the combination of the sole-support and the jack having the slot w, and the block in said slot swiveled to a fixed support,whereby the jack is adapted 5 to oscillate and to move vertically, and a supporting-spring whereby the jack is normally elevated, as set forth.

6. The combination of the jack having the slot w, the fixed pivot, and the swiveled block thereon located in said slot, and the spring interposed between the block and the upper end of the slot, as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 17th day of September, 1884.

PETER A. OOUPAL.
