Fig. 4 is a is fitted a block d grooved upon opposite top plan viewof one of the supporting-plates sides to engage the plate in which the slotis which in the preferred formof my invention formed and free to reciprocate along said support the pad-sections.

Fig. 6 is a formed of an upper plate 3 and-a lower plate I 4, between which is formed a socket d to which is fitted a ball d. The ball cl is secured to the lower end of a threaded bolt al which is provided with a correspondinglythreaded bearing in the bed A. To permit the ball (1- to be inserted in the socket d", the upper plate 3 is formed of two sections 5 and 6, the perforation 7, which receives the bolt d being formed partially in each. The sections 5 and 6 are bolted or otherwise suitably secured to the plate 4 to form the block (1 The lugs 2 2 are projected above the plates (1, d, and (1 to which they are secured, and engage the sides of the bed A, acting to prevent any lateral movement of the plates cl, (1, and d From opposite ends of the bed A are projected the downwardly-extendin g lugs a a through threaded hearings in which extend the correspondiugly-threaded bolts 6 e, the inner ends of which bear against the vertical shoulders (Z d t secured, respectively, upon the supporting-plates d and (1 The above-described arrangement is such that by turning the bolts 61 d the .plates d, cl, and d? and the pad-section b, b, and I) carried thereby may be tippedlongitu'dinally and set at any desired angle, and then by turning the bolts 6 e the plates cl d (Z and their supported pad-sections may be moved longitudinal-1y to approximate their adjacent ends, the blocks (Z sliding in the slots (2 or, it the change of inclination brings the-sections b, b, and 19 too closely together, the bolts 6 6 may be turned in an opposite direction and the sections 1), l), and I) allowed to move apart. I desire to say in this connection that while I prefer to have all the pad-sections movable, as hereinbefore described, such arrangement is not essential to the present invention, and good results can be secured by arranging the toe and heel sections, or even the toe-section alone, to be movable, as hereinbe'fore described, while the other sections are arranged in the usual manner.

In practice I provide in each-ofthe lugs a a slot a, which receives the shoulder (1 so that said shoulder further acts to's-teady and guide the plate to which it is attached.

I wouldfurther say that in practice I provide a proj-ectedshank-section b, and in connection therewith a spring=supported shanle block f, which bears upon the projected shank portion with a yielding pressure, which may 'be regulated by means of the adjusting-bolt f. I do not, however, consider a detailed description of the shank-block and itscontrolling mechanism necessary in the present application, as the same isshown and fully-described in another application filed January 14, 1896, Serial No. 575,491. Imay say, however, that when theshank-block f-is used the plate cl is cut away at f (see Fig. 6) to receive the upper portions of the same, and the sides of the shank-block f are projected be- 3 tween 'thepl-atecl and the p'a'd section bi.

Having thus described my invention and its mode of operation, I claim as novel and desire to secure by Letters Patent of. the'United States- 1. In a pressing-form for sole-laying machines the combination, with a suitable support therefor, of an elastic pad comprising heel and shank sections, and an independent toe-section, arranged to tip longitudinally to vary its longitudinal inclination, and movable longitudinally toward and from the shanksection, substantially as described.

2. In a pressing-form for sole-laying machines the combination with a suitable bed, of a series of independent supports on said bed, a series of independent elastic pad-sections mounted upon said supports, and an elastic reinforcing-strip interposed between each section and its support and covering substantially the edge-pressing portion of each section, substantially as described.

3. In a pressing-form for sole-laying machines the combination, with a suitable support therefor, '01: a series of independent padsections, means for tipping said sections to adjust their longitudinal inclination, and means for longitudinally moving said sections to approximate or separate their adjacent ends, substantially as described.

4. In a pressing-form for sole-laying machinesthe combination with a suitable bed, of a series of supporting-plates supported from said bed, a series of hollow elastic pads'ections mounted upon said plates, means for tipping the plates to adjust their longitudinal inclination, and means for longitudinally moving the plates to approximate or separate their adjacent ends, substantially as described.

5. In a "form for sole-laying machines the combination with a suitable bed, of a series of independently-1novable supports secured to said bed, independent toe and heel pressing sections and a projected shank-pressing section mounted upon said supports, and a yieldingly-supported shank-block interposed between the sllanlepressing section and its support, -substantial'ly as described.

6. Ina pressing-form for sole-laying machines the combination, with a suitable support thereforof an elastic pressing-pad, comprising an independently-movable section, and a longitudinally tipping and sliding support for said section, substantially as de scribed.

7. In a pressing-form 'fo'r sole-laying machines the cembination, with a suitable bed, of an elastic pressing-pad comprising an indepen dently movable section ,an independent support for said section, and a sliding and tipping connection between said support and bed, substantially as described.

8. In a pressing-form for sole-laying'machines the combination, with a suitable bed, of an elastic pressing-pad comprising an independently-movable section, a longitudinally-slotted plate supporting said section,

ICC

and connections between the plate and bed chines, the combination, with a suitable bed, of a pressing-pad comprising an independently-movable section, and a support for said section interposed between the same and the bed, and lugs on said support arranged to engage opposite sides of the bed, substantially as described.

In testimony whereof I have hereunto set my hand, in the presence of two attesting witnesses, this 7th day of February, 1896.

ERASTUS E. WINKLEY.
