Boor-TREEING MACHINE.

SPECIFICATION forming part of Letters Patent No. 289,044, dated November 27, 1883.

Application filed March 1983.

To all whom it may con/cern:

Be it known that I, JOHN VARREN, of Bos ton, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Boot-'freeing Machines, of which the following, taken in connection with the accompanying drawings, is especification.

ll/Iy invention relates to a machine for rub- 1o bing the exterior surfaces of boot-uppers in the operation technically known as treeing; and it consists in the employment of certain novel devices and combinations and arrangements ofv parts, which will be readily understood by reference to the description of the drawingaand to the claims, to be hereinafter given.

Figure l of the drawings illust-rates a sectional elevation of a machine embodying my eo invention, the right-hand half of said figure representing an elevation with the shank-rub hing wheel removed, and the left-hand portion representing a central vertical section in a plane at right angles to the wheel-shaft. Fig.

2 is a central vert-ical section in a plane through the axis of the wheel-shaft. Fig. 3 is a partial section on line :c a" on Fig. 1, showing the position of one ofthe tlexible rubbers when in operation upon a bootleg with the tree 3o therein; and Fi g. A represents an elevation of the sh ank-rubbing wheel with the leather covering removed from the right-hand half thereoi'.

A is a column, provided with the base-flange A and the two upwardly-projecting arms A A?, in the upper ends of which are formed the hearings A A3, in which is mounted the shaft B, having firmly secured upon one end the driving-pulley C and upon the other end the 4o shank-rubbing wheel D, as shown.

E E are two disks or wheels iitted to t-hc shaft B, between the bearings A3 A3, in such a manner that they may be moved toward and from each other upon said shaft, while they are compelled to revolve therewith. The hubs of the wheels E E have set therein keys or feathers a, which also fit into and slide in grooves formed in the shaft B in a well-known man- 1 ner.

F is a spiral spring surrounding the shaft B, between the hubs of the wheels E E, and

(No model.)

acting thereon by its tension to force said wheels apart.

G G are two rings iitted loosel7 upon the shaft B, outside of the wheels E, each in close proximity tothe hub of one of said wheels, and pivoted to the upper end ofone of the elbow shipper-levers II H, which levers are pivoted at Z1 b to ears c, formed upon the inner sides of the arms A A2, and forked at their upper ends, and provided with pivotal pins or centers d to receive'the rings G G, as partially shown in Fig. 1. The lever-arms of the shipper-levers II H project inward or toward each other till they nearly meet, and are connected by the links e e and rod f to the treadle I, pivoted by its rear end within the column A, and projecting through the slot g, cut ,through the front side of the column A, as shown.

J is apawl-lever pivoted to the treadle-lever I, and arranged to engage with the ratchetteeth 7L, formed upon the column A, on each side of the slot g, for the purpose of retaining the wheels E E at the required distance apart when they are moved inward by depressing the treadlelever I, to adapt them to a-ny particular job.

A series of leather tubes, K, are arranged at regular and equal distances from each other around the peripheries of the wheels E E, with their central portions curved inA ward toward the shaft B, and their end portions radial thereto, said tubes being bent around grooved pulleys i i, mounted in slots formed in the peripheries ci' said wheels, and each being connected at each end to a spring', j, the other end of which is connected to a pin set in the hub of the wheel E, as shown in Fig. 2. The leather tubes K are filled with a core, k, of some ileXible material-suoh as a cord oi' leather or textile material or powdered soapstone-and have secured to each endthereof a metallic coupling, L, composed of the sleeve Z and plug Z', the latter being provided with the eye an, as a means of connecting the spring j thereto, and screwed into the sleeve l, as shown. The greater part of the lengths of the sleeve Z and plug l are made tapering, or in the form of frustums of cones, and the conical periphery of the plug Z is roughened by forming thereon a screw-thread adapted to IOO ` purpose of preventing the tubes K from being ribs m of the wheels E E, and said pulleys are press it, and thus move the wheels E E toward cutting it, as'shown in Fig. '2.

Thepulleys'i i are provided with journals which rest in slots formed in the edges of the press into the leather of the tube K without prevented from leaving said bearings, in case of the breakage of a tube K whileA the wheels E are in motion, by caps or guards over said journals, as shown at n in Fig. l.

An endless band or hoop, M, is fitted closely to and secured upon the periphery of cach of the wheels E, as shown in Figs. l and 2, for the displaced from the pulleysz "i, said hoops being made preferably of metal and covered with leather.

The shank-rubbing wheel D consists of a plain circular metal disk, n, provided with a suitable central hub, and meansof securing it iirmly to the shaft B, and having cast upon its outer radial face a series of lugs, n2 n2, upon each of which is secured a block of wood, o. the outer face of which is curved to the desired shape, as shown in Fig. 2.

The blocks of Wood o and the lugs n', with the beveled periphery ofthe disk, are covered with leather o', which is first molded to the desired shape, then placed in position on the wheel D and secured thereto by the metal clampingrings p and q, secured to the wheel by suitable screws, as shown in Figs. 2 and 4.

The operation of my invention is as follows: The `boot being stretched'upon the ordinary tree, the operator takes it in his hand and, holding it in the desired position in contact with one or more of the leather rubbing cords or tubes K, sets the shaft B in motion, to canse thewheels E E to revolve and bring each of the iiexible rubbers K into action upon the boot in succession, the operator meanwhile placing his foot upon the treadle-lever I to deeach other, and cause the flexible rubbers K K to be bent around the boot to a greater or less extent as he presses the boot toward the axis of the shaft B, and at the same time turning the boot in his hands, as maybe required to present all parts of the boot-upper that can be touched by the rubbers K into position to be acted upon thereby.

In order to finish those portions of the upper in proximity to the sole-edge along the shank and fore part of the boot, the operator applies those parts of the boot to the action of the wheel D. By this means all parts of the boot may be acted upon by the machine, and

the treeingl may be completed without other hand-work than placing the boot upon and removing it from the tree.

What I claim as new, and desire to secure by Letters Patent of the United States, is-

'lf In a machine for treeing b oots, oneor Amore iiexible rubbers in the forni of round cords or bands, arranged in planes radial to, and extending longitudinally of, and adapted to be revolved about an axis of motion, and to be bent or wrapped partially around the boot by contact therewith, substantially as described.

2. In a machine fortreeing boots, a series of flexible rubbers in the form of round leather cords or straps, arranged in radial planes around and equidistant from a common axis,

about which they may be revolved, and adapted,

to be brought successively into contact with the boot to be treed, and to be bent partially? anism for moving the wheels E E toward and from each other, substantially as and for the purposes described.

5. 'Ihe combination of the shaft B, the Wheels E E, a series of flexible rubbers, K K, a series of pulleys, il i, a series of springs, j j, the spring F, the two shipper-levers H H, connected to and adapted to move said wheels E E toward each other, the treadlc-lever I, and means of connecting said treadle to the levers H H, substantially as described.

6. The wheel D, composed of the metal disk n', provided with the lugs of n, the wooden blocks o 0, leather coveringo, and the clampr ingrings p and q, all arranged and combined substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 20th day of March, A. D. 1883.

JOHN XVARREN.
