BO OT AND SHOE SOLE SHAPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 300,039, dated June 10, 1884.

Application filed April 5, 1884. (No model.)

10 aZZ whom, it may concern Be it known that I, MAURICE V. BRESNA- HAN, of Lynn, in the county of Essex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Boot and Shoe Sole Shaping Machines, of which the following,taken in connection with the accompanying drawings, is a specification.

This invention relates to machinery for shaping boot and shoe soles after they are attached to the upper; and the object of these improvements are to provide improved means for operating the mold, forcing it against, and withdrawing it from the sole; to provide a suitable support for the shoes which will admit of the movement necessary to adapt the sole to the mold; and it further relates to improvements in the construction of certain parts of the operative mechanism, to be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view showing the end and one side of a machine embodying two duplicate sets of mechanism, and each set embodying my invention. Fig. 2 is a side elevation, and presents a single set of such mechanism withone side of the frame-work removed to better illustrate the several parts as they appear relatively to each other while in the act of molding the sole, and also, by dotted lines, the position of the same parts when in position to permit the taking off and putting 011 the shoe. Fig. 3 is a plan View of two sets of mechanism, and illustrates, together with Fig. 1, the manner of combining two or more sets of mechanism in one frame.

In the drawings the frame-work of the machine is designated by the letters A, which are placed on the several branches thereof. The form for supporting the boot or shoe has a foot portion, B, shaped like the ordinary last, always with due respect to the shape of the intended sole. It is mounted, as shown, on the rock-shaft O, in order, first, that it maybeturned upward, as designated by dotted lines F in Fig. 2, to facilitate in the operation of putting on and taking off theshoe; and, second, to

allow the movement necessary to permit the form to. adapt itself to the mold D when brought against the same under pressure. The mold D is formed with due regard to the style of the intended sole, all in the usual manner, and it is detachably connected to the end of rod H, which rod H is arranged as shown in block R, and is provided with a suitable thread adapted to work in screwwheel, M, also mounted in the block R in such manner that turning the wheel operates to move the rod longitudinally in the block; Said block R has its lateral edges groovedor concaved to fit the rods P P, by and between which it is supported, and along which it is reciprocated longitudinally for the purpose of carrying the mold up to and away from the sole, as referred to hereinafter. The said longitudinal movement of the block R is effected by operation of the toggle-arms 2 3, and these in turn are operated by the mechanism composed of parts 4, 5, 6. 7, 8, and 9, arranged as fully represented in Fig. 2, 8 being a crankshaft adapted to be revolved by any suitable power applied to the wheel 9 7, an arm mounted'loosely on crankshaft 8, and bearing on its end the plunger 6, the two being connected by a screw-joint, as shown, to permit change in length. Said plunger 6 fits loosely in the sleeve 5, and isallowed to slide therein,

as referred to hereinafter. Said sleeve 5 unites with lever 4, the opposite end of which lever 4 connects, as shown, with the toggle-arms 2 3'. The,levers 10 and 11, arranged as shown in Fig. 2, afford convenient and ready means whereby the operator may bring the mechanism composed of parts 4, 5, 6, 7, 8, and 9 into position to force upward the arms 2 3, and thus drive forward the mold D; or the same parts may by a reverse movement of the levers 10 11 be pushed backward into the position represented in Fig. 2 by the dotted lines,

as and for the purposes referred to hereinafter. In operating the machine the workman first draws the shoe over the form B while the form is turned up, as indicated by dotted lines F in Fig. 2. He then turns the form over in line end of sleeve 5, and force upward the togglearms 2 3, thus carrying the mold D forward against the shoe-sole,for the purpose of molding or shaping the same. The toggles 2 3 will now have passed upward by this operation past the center line, and are there held in position by the projections e 6, so that when. the

shaft 8 draws down the plunger 6 it will slide loosely in the sleeve 5, and allow the toggles 2 3 to remain in position to keep the pressure against the sole. This arrangement avoids the necessity of stopping the machinewhile the process of molding the sole is going on. The workman may now turn his attention to molding a sole on the next adjoining set of mechanism, and, for the purposes of convenience as well as economy in manufacture, several sets of mechanism-a half dozen, or more or less-may be united in one frame and run by one driving-shaft, as and in the manner illustrated in Figs. 1 and 3 of the accompanying drawings, passed through the entire set, and coming back to the first shoe,which, by this time has been quite molded, desires to release the same from pressure and remove it from the machine. He grasps in one hand the lever 11, and, reaching round the rod 20, presses it inward against the lever,which operates to throw backward the sliding rod 21, and trips thelever 22, to press inward the rod or pin 23, so that as the plunger 6 reaches the end of its next upward slide in the sleeve 5 the said pin 23 will be pushed into a suitable hole near the end of the plunger, and thereby lock the sleeve and plunger together, so that the next downward throw of the shaft 8 will draw downward the toggles 2 3, thus removing pressure from the shoe-sole. The mechanism composed of the parts 4 5 6 7 may now, by an obvious move ment of the lever 11, be thrown backward into the position indicated in Fig. 2 by the dotted lines d. Pressure may then be removed from rod 20, allowing the pin 23 to be drawn out ward by spring f, thus releasing the plunger 6 and allowing it to play loosely in the sleeve while the workman turns up the last or form B to remove and put on the shoe, whereupon the operation of again clamping the secured shoe is the same as before described.

It will be observed that the last or form B, by being mounted, as described and shown,

on the rock-shaft 0, not only permits being turned upward to put on and take off the shoe, but it also more readily adapts itself to the mold D than when mounted in the usual manner upon a fixed support.

The position of the moldD relatively to the the form 13 may be varied by operation of the screw-wheel M, as above described, so as to accommodate the machine to soles of different thicknesses, as also to regulate the amount of pressure on the sole.

To prevent breaking the machine,as well as to give elasticity to the pressure, a spring or sheet of rubber is placed under the mold in the usual way.

I claim and desire by Letters' Iatent to secure- 1. In combination with the mold D, the form B, said form being mounted ona movable support, 0, and adapted to operate in connection with the mold, substantially as and for the purposes described.

2. In combination with the mold D,the block R, and togglearms 2 3, and the parts 4 5 6, arranged substantially as described, and a suitable driving meehanism, substantially as set forth.

tially the construction described, the combination of lever 4, sleeve 5, plunger 6, and pin 23, said parts being combined and adapted to operate substantially as and for the purposes above set forth 4. In a sole-shaping machine of substantially the construction described, the combination of lever 4, sleeve 5, plunger 6,arranged to operate as set forth, and a clamping or interlocking mechanism adapted to interlock. the sleeve 5 and plunger 6, substantially as andfor the purposes described.

5. The combination of the lever 11, rod 10, lever 4, sleeve 5, plunger 6, and pin 23, all adapted to operate substantially as set forth, and means, substantially as shown, to operate the pin 23, said means being extended upward along the lever 11, as and for the purposes set forth.
