IMPROVED ROLLING OR POLISHING MACHINE.

Specification forming part of Letters Patent No. 38,257, dated April 2l, 1863.

To all whom it may concerm- Be it known that I, BENJ. Q. BUDDING, of Milford, in the county of Worcester and State of Massachusetts, have invented a new. and useful Machine for Rolling or Polishing; and I do hereby delare that the following, taken in connection with the drawing which accompanies and forms part of this specification, is a description of my invention sufficient to enable those skilled in the art to practice it.

My invention consists ina machine for solidifying the soles of boots and shoes when in process of construction, and while upon their lasts]7 which solidifyin g operation, intelligently directed, produces the desired form of surface, and also leaves the surface and edges of the soles in a condition to be easily and highly nished. This operation is sometimes technically termed leveling, and is performed by my invention by the movement of a roller, or of a rubber actuated by the combined impulse of power andof the operator, the application of the roller or rubber being controlled and directed by the operator. The operation is that heretofore produced by manipulations with ahammer and rubbing-stick, though these did not produce the desired result nearly as well or as rapidly as does my machine.

The drawing represents my machine in plan and in elevation, sections being made through same parts shown in elevation to illustrateV better the detail of construction.

The mechanism consists of two distinct parts, each of which has its own function, and which are separately operated and may be separately. considered. One part is the holder or jack for holding or jacking the boot or shoe, so as to present it firmly to the action of the other .part of the mechanism, which consists of a roll or rubber, and the machinery per end, so that the piece g, which carries b, can yextend into it, and so that the shoulder upon which the last 7L rests can be raised or v lowered, and lixed by a set-screw according as the lasts are high or low. o may be made of considerable length, so that the long legs of boots can be placed over it Without coinpressing, folding, or turning them. b is pivoted to g, so that it may assume any desired angle with the axial line of c and g, which angle is regulated by the set-screw t'.

It will be seen that movement of o toward a will clamp or cramp7 the last and shoe firmly in position, with the toe resting on a. To` effect this forward movement of o there is provided a treadlelever, j, pivoted on 7c, which bears, pivoted upon an arm, l,y affixed thereto, a long pawl, m, which engages with the teeth of f, being held up in position, soto do by the spring n, iiXed in the frame. j is also provided with a spring, o, iiXed in the frame, of j sufficient elasticity to keep j elevated to its highest position when left free to move.

It will now be seen that the shoe is clamped upon the toe-piece a, by depression by the operator of j, thus moving the pawl m forward, and inclining o toward a. The lever j is held in that position, which clamps the shoe by means of a catch or tooth which engages with the notched bar p.

When it is desired to release the boot or shoe from the jack, the opera-tor gives a sidewise movement to j, which unlocks it from p, and the spring o carries j to its highest position, which causes m to impinge against stop q, thereby bending n and releasing m from f, leaving o free to be inclined backward by the operator, thus unclamping the boot or shoe, which is then removed.

VTo actuate the roller r or rubber, power is applied to shaft s, which, by means rof the bevel-gears shown, rotates a vertical :shaft in the support t, on which shaft is xed a disk provided with a slot by which the throw of the crank u can be varied. This crank carries a connecting-rod, w, which has at o provision for vertical vibration of w, and at x provision for torsion of w. The other end of the connecting-rod is pivoted to a yoke, y, which can turn on the shaft on which the roll t revolves, and which connects the two parts of the crosshead z, which through the means-described is reciprocated back and forth on theslidcs a.

The slides a' and pieces b form a frame, which is pivoted to and supported in a box, c', which box is pivoted at d to the supportf. It will be apparent that the slides can be inclined in any direction from a horizontal plane, and that when horizontal orso 'inclined the rotation of crank a will reciprocate the roll or rubber back and fort-h on the slides.

The position of the frame a a b bI is controlled by the operator through the medium ot' the handles d', and the connection e with the lever f', which is pivoted at 7c, and whichy the counterbalance-weight g tends to keep elevated. llhe connection of e with f is made by means of a long leaf-spring, h, which is secured to f near 7c.

Suppose a boot or shoe to be jacked in position, and the crank a to be rotating, it will be evident that the roll r will be reciprocated over the Surface of the sole, and that by treading onf the roll can be made to bear on the sole with more or less force up to the limit of the bending of the spring IL', the stiffness of which can be increased by sliding the strap i toward the operator. The roll can be made to operate on every part of the surface of the sole by means of the handles d.

The roll is shown as concave, and long enough to be put in contact with an y part of the widest sole. The roll, however, might be of any other form desiredconvex, cylindrical, or conical. For some purposes the roll might be narrow, orornamental figuring might be engraved thereupon. The frame a' a b b might be arranged so as to be capable of having a movement from right to left, and vice versa, which would be accomplished by mounting` the horizontal pivots d of the box c on a vertical pivot. While the roll serves best to solidify the sole and bring it into shape, a rubber will probably produce the best polish. A fixed rubber of any suitablematerial may be made to take the place of the roll, or the roll m-iy be locked and prevented from rotating, thus forming a rubber. The spring h allows the roll or rubber to yield so as to pass, without particular attention on the part of the operator, over irregularities of surface-such, for instance, as where a tapsole terminates near the shank.

While I have described my machine as adapted to operate upon boot and shoe soles, it is evident that it may be employed as well to advantage in otherbranches of the mechanic arts to shape, condense, and polish other materials than leather, and also that the devices for imparting motion to the roll orrubber, and for controlling` its position and pressure, may be modified from those shown and described herein without departing from the spirit of my invention.

I am well aware that it is not new to polish leather or other substances by rollers or polishing-iools hung on vertical levers, and worked by hand over the surfaces to be polished, nor to apply springs in connection therewith to produce pressure, or to release the article being polished from pressure, nor is it new to give a polishing tool by hand or by mechanism a reciprocating movement overV the surface being polished, nor is it. new to produce great pressure on such surface by means of clamps operated by hand-levers or treadles. Devices for attaining these results are common, and may be found in many machines where friction ot' rolls or other tools is used. (See, for instance, machines patented in the United States by W. Gobwin in 1839; by John Gardner in 1843; by J. H., J. M., and H. tg. Thompson in 1855, and by G. W. Pruyne in 1&56.) vBut I believe it is novel to combine with a'mechanism for rigidly holding in position a boot-sole or other article being polished, with a mechanism for giving a reciprocating longitudinal movement to the polishing-tool over such surface, such mechanism being at the same time combined with other devices which allow at the same time angular, vertical, and transverse movements to be given to the polishingtool, as described.

l. Combining, with a holding mechanism a mechanism which, while carrying a roll or rubber back and forth, at the same time permits vertical and angular movements to the roll or rubber, for the purpose of adaptation to curved or irregular surfaces or outlines.

2. Controlling the clamping or holding of the matter to be operated on through the medium. ot' the treadle j and its spring o, the ratchetf", pawl m and its spring n, and stop q, or their equivalents.

v Combining with the waysa (if, over which the rubber or roll is reciprocated, the transverse or rocking levers b', rod e', and lever j", operating together, for the purpose asabove Y set forth.
