MACHINE FOR TREEING BOOTS.

SPECIFICATION forming part of Letters Patent No. 239,351, dated March 29, 1881.

Application filed February 15, 1881. (No model.) I 7 Natick, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Treeing Boots, of which the following, taken in connection with the accompanying drawings, is a specification.

' My invention relates to a machine for treeing boots, and is an improvement upon Letters Patent No. 232,078, granted to me Sep tember 7, 1860; and it consists in the addition ofa joint to the sliding strap-guiding plate, whereby its lower end may be swung about a pivot, thus greatly facilitating the operation of the strap upon the foot and toe of the boot.

It further'consists in the combination, with the swinging frame, of a toggle-connection, one

end of which is pivoted to said frame and the other end to astationary stand, and a weight attached to said toggle, which serves tocounterbalance the weight of the frame when swung from a vertical into an inclined position, thus reducing the labor of operating the machine. It further consists in connecting to the sliding strap-guiding plate a treadle mechanism and attaching a weight to the treadle, the treadle and its connecting mechanism enabling the operator to press the sliding plate downward, thus bringing the strap to bear with increased pressure upon the boot, and the weight serving to counterbalance the weight of said sliding plate when no extra pressure is needed.

It further consists in certain other details of of the lower portion of said frame, showing the parts in position for operating upon the foot of a boot. Fig.6 is a horizontal section on line arm on Fig. 1, looking downward; and

Fig. 7 is a partial horizontal section on line 3 g on Fig. 1, also looking downward. Figs. 4t0 7, inclusive, are drawn to a scale one and one-half time as large as the scale of Figs. 1, 2 and 3.

A is the driving-shaft, having its hearings in the hangers B B, and having secured upon one end thereof the fast pulley a, and mounted loosely thereon the loose pulley a, which serve, in connection with abelt and shipping device, (not shown,) to set the machine in motion and stop it at the will of the operator in a well-known manner.

0 is a swinging frame, suspended by bearings b I) from the shaft A, and having cast upon or secured to its front side, near the upper end, suitable guideways, to which are fitted the two sliding blocks or cross heads D D, adapted to reciprocate in a vertical direction, motion being imparted thereto through the medium of the connecting-rods c c by the two cranks d d, forged in one piece with the shaft A.

E E are two cords or round belts, attached at their upper ends respectively to the two cross-heads D D,and, passing downward from thence around the inner-edges of the guiding pulleys or sheaves e e, thence around the outer edges of the sheaves f f, thence around the inner edges of the sheaves e c, thence in contact with the sheaves g g, are secured at their lower ends to the ends of the strap G. The sheaves e e and c e are mounted upon pins set in the swinging frame 0, while the sheaves ff are mounted upon pins set in the ends of the take-up levers F F, which are pivoted at f f to the frame 0, and are adapted to take up the slack of the cords E E. The free ends of the take-up levers F F are moved outward or inward by the links F F, each pivoted at one end to a lever, F, and at the other end to the sliding plate H, having tongues or ribs on its rear side fitted to slide in a groove, h, in the frame 0, the plate H being held against the a suitable surface on the back of the frame G.

Instead of prolonging the lower end of the plate H into two ears rigid therewith, as in my former patent, before cited, I pivot thereto, by the pin 7L2, a forked frame, composed of the two arms I I, connected by a suitable bar at the top.

To the lower ends of the arms I I are pivoted the levers or strap guides J J, in the lower ends of which are mounted the rolls jj, which are made quite small in diameter, in order that the strap Gr may be pressed firmly against the shank portions of the boot.

In a slotted portion of each of the strapguides J J is mounted a sheave, J, which acts as a guide to the strap G, the face of the sheave being made flat for that purpose, and the slotted portion of the guide or lever J surrounding said strap to prevent it fromslipping off from the face of the sheave J.

To the lower ends of the guidesJ J, in close proximity to the rolls j j, aresecured the handles j j, by which the operator guides the strap Gr over the surface of the boot. I prefer placing the handles jj in the position shown, as an improvement over myformer patent, as by so doing they are brought closer to the boot and working portion of the strap Gr, thus enabling the operator to guide it with greaterease over the surface of the boot and press it into the curves of the shank portion thereof.

By pivoting the arms I I to the plate H they can be swung at an angle therewith, to-

gether with the strap-guides J J, either in a forward direction or slightly toward the rear, for the purpose of effectually rubbing down the foot and toe of the boot. The are through which the arms I 1 can be swung toward the rear of the machine is limited by the lug 2' coming in contact with a shoulder, 70, on the plate H, and the forward motion is limited by the lug 41 coming in contact with the set-screws It is, screwed into an car on the plate H, said set-screws thus making the limit of the forward motion adjustable, and should be so adjusted that when the frame I I is swung forward to its stop it shall be in proper position for the strap G to act upon the foot of the boot.

The sheaves g g are mounted on pins set in the brackets l l, which are secured to the frame I I, said sheaves serving as guides to the cords E E as the frame I I is swung about its pivot 1L To each of the brackets I I is secured a hook, l, as shown in Fig. 7 which partially surrounds the cord E and prevents it from slipping off from the sheave 9. For a similar purpose four small guard-plates, m m and an, are fastened to the frame 0 in close proximity to the sheaves e c and c 0, respectively; also, portions of the forked ends of the take-up levers F F surround the cords E E as addi tional guides to the cords in their rapid reciprocation.

In my former patent the take-up levers were made curved or angular in form, and were thrown outward by the cam-shaped upper end of the sliding plate H; but I prefer to operate them, as here shown, by the links F F, inas- A handle, 1, is attached to the plate H, by

which it may be raised or lowered.

K is a table, supported upon legs K K, which may be firmly secured to the floor, and having bolted upon it the stand L, to which is secured the swiveling boot-tree M, carrying the boot N. The treadle and mechanism connected therewith for operating the boot-tree to stretch the boot N thereon, forming no part of mypresent invention, are not illustrated in the drawings.

To the rear of the swinging frame 0, at or near its lower end, is pivoted one end of the toggle-connection O, jointed at O, and connected at its lower end to the stationary stand 0 bolted to the top of thetable K. Aweight, P, is suspended from a hook at or near the joint 0 of the toggle O, and serves to counterbalance the pressure caused by the tendency of the swinging frame 0 and mechanism mounted thereon to assumea vertical, or nearly "ertical, position. When the frame 0 is at rest in a normal or nearly vertical position the weight P is nearly in a vertical line over the pivotal connection of the toggle O to the stand 0 thus exerting little or no pressure against the frame 0; but as the frame 0 is swungfor- Ward to allow the strap G to act upon the foot of the boot the weight P also moves forward, causing the toggle O to exert a greater pressure upon the lower end of the frame 0, thus effectually counterbalancing the increasing tendency of said frame to swing backward to its normal position. The above device constitutes one of the important features of my present invention, and greatly reduces thelabor of operating the machine.

To the upper end of the sliding plate H is attached, by the pin 9, a rod, Q, adapted to slide up and down with the plate H, its upper end being guided in a bearing, 19, on the back of the frame 0.

To the upper end of the rod Q is attached one end of the link q, the other end of said link being attached to the lever B, pivoted at the center of its length to a suitable support, i". To the opposite end of the lever It is attached a rod, S, which extends downward, and is connected at its lower end to one end of the treadlelever T, pivoted at or near the center of its length to a cross-tie connecting the legs K K of the table K. A weight, U, is secured by a suitable set-screw to the treadle-lever T, it be the boot at the commencement of the operation of treeing, and also to bring the strap G to bear with greater pressure upon the boot whenever such pressure is needed.

The link q might be attached directly to the sliding plate H; butIprefertointerpose therod Q, as by so doing the pointof connection with the link (1 is brought nearer to the point of suspension of the swinging frame 0 thus decreasing the tendency of the weight U to exert a force upon the frame (J to pull it backward or toward a vertical position.

What I claim as new, and desire to secure by Letters Patent of the United States, is-- 1. In a boot-treeing machine provided with a flexible reciprocating rubber for acting upon the boot, the combination of the swinging frame 0, the reciprocating or sliding plate H, the forked frame I I, pivoted to the plate H, and adapted to be moved about'an axis in a plane parallel to the plane of movement of the frame 0, the levers J J, pivoted to the frame I I, and adapted to move in planes at right angles to the plane of movement of said frame I I, and suitable pulleys or rolls for guiding the rubbing-strap in its movements, substantially as described.

2. In combination with the swinging frame 0, having mounted thereon the mechanism for rubbing the boot, and a tree-supporting stand,

the toggle-connection O, and the counterbalance-weight P, all arranged and adapted to operate substantially as described.

3. The combination of the swinging frame 0, the sliding plate H, carrying the strap-guiding arms J J, a treadle and suitable connections for moving said sliding plate, and a weight for counterbalancin g the same, substantially as described.

4. In a boot-treeing machine, the combination of the swinging frame 0, the sliding plate H, pivoted frame I I, pivoted leversJ J, take-up levers F F, flexible rubbing-strap G, and connections E E, guiding sheaves or pulleys e, f, e, 9, and J, and mechanism, as set forth, for imparting to said rubbing-strap an endwise-reciprocating motion, substantially as described.

5. The combination of the swinging frame (J, sliding plate H, take-up levers F F, the links F F, the flexible rubbingstrap G, suitable pulleys for guiding. said strap, and mechanism for imparting to said strap a reciprocating end wise motion, substantially as described.

Executed at Boston, Massachusetts, this 12th day of February, A. D. 1881.
