SPECIFICATION forming part of Letters Patent No. 543,147, dated July 23, 1895.

Application filed May 10,1894.

I To all whom it may concern:

Be it known that I, GEORGE H. CLARK, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Machines for Holding Boots or ShoesWhile Being Operated Upon, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts. .In United States Letters Patent No. 417,148, dated December 10, 1889, a jack for holding boots and shoes while being operated upon is shown, comprising a rotatable holder having two separable members, one of which is pro [5' vided with an inclined face and the other with a heel-piece, and a removable fore part is connected with a sliding block which has an inclined bottom and is arranged to slide upon the inclinedface of that member of the holder having an inclined face, the inclination being such as to enable the foot-41. e.,

the combined heel and fore part-to shorten lengthwise as the boot or shoe is withdrawn therefrom or preparatory to applying the boot or'shoe thereto, and this invention has for its' object to improve the construction of the machine therein shown, to increase its capacity, and also to enlarge its sphere of usefulness. The machine is now designed to 50 be used to hold boots and shoes while being treed, or burnished, or shaped, or finished in any desirable way, and by any means which may be selected.

The machine herein shown and in which 5 my present invention is embodied comprises several separable rotatable holders, trees, or jacks supported by or upon a hub having suitable bearings, and the holders, trees, or jacks are adapted to be brought into position 0 before the operator as desired by taking hold of one of the trees, and thereby rotating the hub, or the hub may be otherwise turned for this purpose. Each tree is provided with a wedge or other means by which the parts thereof may be separated, and means are provided, operated by a treadle, for moving the separating-wedge or for operating the separating device of any tree which may be brought into co-operative action therewith, and a locking device is provided for or in connection with each tree, or is so constructed Serial No. 510,742. (No model) as to hold the parts of the trees separated when the separating device is removed from co-operative relation with the treadle mechanism. The holders, trees, or jacks are or may be made alike, consisting each of two essential parts or members, one of which has a heel-piece, which if desired maybe formed integral with it, and the other of which has an inclined or diagonal face, and a slide-block is supported upon said inclined or diagonal face, extendingover or upon the heel-piece, which likewise has an inclined or diagonal face in continuation of the aforesaid inclined or diagonal face, and a locking device is preferably provided for said slide-block, which is or may be operated by the means employed for separating the parts of the tree, and the fore part of the foot is made removable and adapted to be connected with the slide-block by a spring-actuated latch or other securing device and thereby supported.

Figure 1 shows in side elevation a jack embodying this invention for holding boots and shoes while being operated upon, a portion of the framework being broken away; Fig. 2, a front elevation on a larger scale of a portion of the machine shown in Fig.- 1; 'Fig. 3,a longitudinal sectional detail of one of the trees,- the fore part being removed; Fig. 4, a detail showing particularly a longitudinal section of the slide-block; Fig. 5, an under sideview of the slide-block; Fig. 6, a detail of one of the locking devices which may be employed for locking the tree-supporting hub, and Fig. 7 a detail showing one of the locking devices which may be employedfor retaining the parts or members of the. tree separated.

The main frame which supports the operating mechanism comprises essentially two upright standards A rising from a base A. A hub h, having formed as a part of or secured to it a disk or flange h, is secured to a short shaft or journal 71 having its bearings at the upper end of the standard A. Upon one face of the hub it several holes are formed, four being herein shown, (see dotted lines, Fig. 2,) any one of which receives a pin h (see Fig. 6,) projecting throughthe standard A, and having a hub h with a cam-face, which is adapted to bear upon a similarly ca nl-faced boss fixed on the standard A, and a hand-piece h is provided for turning said hub h, and by so doing its cam-face, acting upon the camhub h to be turned. A spring 7t is provided for restoring the hub 71 to its normal position and thereby moving the pin h inwardly. The disk h of the hub 72 has bolted or otherwise secured to the exposed face thereof several boxes 11, four being herein shown, having circular openings or sockets radial to the axis of the hub.

' 'i, yet turning freely therein.

part c at b.

' The holders, trees, or jacks, four of which are also herein shown, each have cylindrical end pieces a, fitting the sockets of the boxes The trees radiate from the hub hand turn in the boxes t'on axes radial to the axis of the hubh. Setscrews 71 pass through the disk 72/, entering circumferential grooves in the cylindrical end pieces of the trees, and by turning them up tightly said trees will be secured in whatever axial position they may be set.

The trees, as herein shown, each consist of two essential parts or members I) 0, one of which, as c, is secured to or formed integral with the cylindrical end pieces and the other of which, as b, is pivotally connected to the These parts or members are hollowed out interiorly or recessed, as will be observed in Figs. 2 and 3. Between said parts or members I) c, and working within the interior recesses thereof, isa wedge-block 51, adjustably or otherwise secured toapin d,which extends through the part c and end piece 0. axially, and said wedge-block bears upon or against or co-operates with two frictionrolls b one above and the other below, and mounted upon transverse pins or studs secured to the parts I) c. As said wedge-block is moved toward the extremity of the tree, or toward the operator, by means to be hereinafter described, the parts I) 0 will be separated, and when said wedge-block is restored to its normal condition, as it will be by means of the spring (1 said parts will close together. The part b has a heel-piece 11 which may be formed integral with it, or secured to it as desired, and one face of said heel-piece as well as a portionof one side of the part 0, (see Fig. 3,) is made inclined or formed diagonally, and in order that the continuityof the inclined faces may be maintained the part b is recesse to receive the outer end of the part c. A slideblock fis mounted upon the inclined face of the part c and heel-piece 5 extending over both parts and terminating substantially flush with the outer end of the heel-piece I)", it having upon its under side a T-slot or dovetailed groove f, which receites a correspondinglyshaped guide-ribf upon the inclined face of the part c, said rib serving as a guide for the blockf as it is moved longitudinally over the inclined face. A rodf is attached to the upper end of the slide-blockf, extending through a boss or projectionf on the part c and in alignment with the direction of movement of the slide-block, at or near the extremity of which is adjustably secured anutf which, by striking against said projection f limits the movement of the slide-block outwardly. A vertical pin it is secured to a spring a, attached to the part c at a point near its outer end, and within the interior recess thereof, said pin extending up through a hole in said part c and adapted when projected outwardly to enter a hole formed in the slide-block, thereby serving as a locking device for said slide-block.

The tendency of the spring a is to raise the pin a, and a cross-piece n is secured to the inner end of the spring, which bears against the under side of the wedge-block d at its forward end, said block having an inclined face at this end in addition to the inclined face employed for supporting the parts I) 0, although the inclination is in a different radial direction. As the wedge -block is pushed forward to separate the parts I) c, the cross-piece n follows along the inclined under side of the block, and the pin a is therefore permitted to rise.

The forward end of the wedgeblock is slotted or bifurcated to straddle the pin n.

The slide-block fis cutaway upon its under side to receive a flat spring-acting tongue f, the outer end of which is slightly turned down, forming a bevel, and has formed in it a hole f and at the outer end of the slide-blockfa keyhole-slot f is formed just back of the perforated portion of the spring-acting tongue.

The fore part g, different sizes of which will be employed, and hence, of necessity, must be made removable, has, as herein shown, an inclined or oblique rear end, which rests upon the upper or outer face of the slide-block f, and upon said inclined'or oblique rear end at or near the sole face of said fore part 9 a headed stud or screw 9' is secured, which, as the fore part is placed in position on the slideblock, enters the keyhole-slot f slightly deressin the s rin -ton ue 6 untilits headed p b O D g, the head of which is confined within a recess 9 next the sliding blockf, and said shinpiece 9 is connected with a shoulder on said slide-block by means of a dowel 9 This shin piece is preferably made of metal and.

shaped to form a proper continuation or extension above the fore part, and it will beseen that as constructed and arranged it is readily removable with the fore part, to which it is attached, and also readily detachable from said fore part. When it is desired to apply a boot or shoe to this tree, the fore part, together with the slide-block f, is drawn outward its full distance, or until the nut f strikes the projection f and with the parts in this position it will be observed that the heel, b is withdrawn, and during the process of applying upon in any desirable way and with any desirable tools, and when it is desired to pull off the boot or shoe the wede-block is permitted to retreat, the parts I close together, and the slide-block f is released, and as the boot or-shoe is then pulled ed the fore part,

. together with the slide-block, will be drawn easily.

out, thereby withdrawing the heel-piece from the boot or shoe, and afterward enabling the boot or shoe to be removed from the fore part As a means of moving the wedge-blocks to separate the parts b c, Ihave herein provided a bell-crank lever pivoted at e to a stud on the framework, one arm, as e, of which is made angular and extends inward into position to act upon any one of the projecting pins d, which may be brought into proper position, and the other arm 6 of which is connected to the upper end of a treadle-rod t, the lower end of which is connected by a spring 25 with a treadle 2?. The treadle t? is normally held in its elevated position by a spring 6 one end of which is -attached to the framework and the other end to an arm projecting from the bell-crank lever. Thus as the hub his turned and the trees successively brought into position before the operator the pins'd will be brought into proper position to be engaged by the treadle mechanism.

, desirable when shaping or treeing the boots or shoes, and-to accomplish this result I have pivoted a cam m on one of the parts-as c, for

instance-which acts upon a pin on, projecting from the other-part, and as the parts are separated this cam turns and thereby holds the parts in whatever positionthey may be set by the wed ge-block. A spring m is connected with the cam m, so that it will be turned by the action thereof as the parts are separated, and a hand-piece m projects from the cam m,

which enables it to be restored manually.

To turn the tree-supporting hub h the pin h will be withdrawn by turning its handpiece 72. and then taking hold of one of the trees and advancing it the next tree will be brought into position, and the correct-position may be determined by the pin h entering the next hole.

The machine is herein shown in connection with a tool or brush for finishing the boot or shoe. This contrivance consists of a counterbalanced arm B, having its bearings at the upper end of two uprights B, erected upon the standards A, and a driving belt-pulley is mounted uponthe shaft 0, which is connected with a belt 0', over which passes a belt 0 which passes around a belt-pulley 0 secured to a short upright shaft having its bearings at one end of the counterbalanced arm, and

to said shaft-a flexible shaft 0, herein shown, I

as covered with rubber tubing, is connected, and to the lower end of this flexible shaft a rotary brush 0 is attached. To limit the movement of the counterbalanced arm. B in each direction chains 0 are attached at one end to the arm and at the other end to the standards B. This tool is adapted to perform a part of the work which is now commonly done by hand.
