The drawing accompanying this specifica- Heretofore, in machinery for setting soletion represents, at A, a jack of any suitable edges the burnishing-tool has been a rotary character for properly supporting a boot or one, but I have found that for certain grades shoe while the sole of the latter is being operof work, and the better to adapt the tool to ated upon, this jack being mounted in an adthe irregular curvature and angle of the sole justable manner upon the top of a curved or heel, a reciprocating or vibratory motion standard, B, which standard is in turn swivof the tool is preferable; and in order to careled upon the top of a table or platform, 0, ry out the purposes of my invention by so duly supported upon the top of two swinging adapting said burnishing-tool that while travor rocking standards, D D, whereby the jack eling about the circumference of the sole it and the boot carried by it may be advanced shall act thereupon with areciprocating or vito or removed from the burnishing-tool. In bratory motion I have devised the following rear of the rocking table 0 I erect, upon the mechanism, in which I have so arranged defloor of the apartment containing the machine, tails as to instantly bring into action either a or upon the base of such machine, two upright tool which reciprocates to and fro of aright or standards, E E, and between these standards curved line, or vibrates upon its own pivot, or I mount an upright swinging or rocking standboth reciprocates and vibrates, substantially ard or frame, F, to the upper part of which as hereinafter explained, the novelty in the frame I pivot, by a stud, a, a horizontal, flexinvention consisting in the adoption, in conible, or swinging arm or beam, G, which pronection with a boot-supporting jack, of a burjects forward toward the jack, this beam benishing-tool so mounted as to act upon the ing balanced or overbalanced in any suitable entire sole-edge with polishing effect, resultmanner in order to relieve the operator of ing from a reciprocating or vibratory, or comthe labor of supporting its weight, the standpound reciprocating and vibratory motions. ard E being provided with oppositely-disposed To this end, and in pursuance of the object of springs 11 H or their equivalents, whereby it my invention in one manner in which the same is held in any position in which it may be left. may be eflected, I employ, as herein shown, The burnishing or setting tool is shown at c first, a jack of proper construction for supportin the drawing as an oblong bar pivoted pracing the boot or shoe and advancing to the imtically at about its center to one side of a mediate vicinity of the burnishing or setgrooved block or carriage, d, which is mountting tool and, second, a burnishing-tool ed upon the outer end of the beam G before swiveled upon a carriage which either slides named, the lower end of the said bar being fashioned into the requisite form to obtain the desired outline to the'sole-edge. In order to vibrate or rock the tool 0 upon its pivot while the carriage d is stationary or reciprocating with short intermittent movements, I fulcrum at about its center a long upright lever, c, to the side of the standard E, the oscillations of this lever upon its fulcrum f being induced by connecting its lower end to the wrist-pin g of a crank or crank-wheel, h, aflixed to the end of a horizontal shaft, '5, mounted in a suitable standard, j, erected between the standards E E before named, the upper end of the said lever being connected to the rear end of a pitman, k, which lies alongside of the beam G and follows its vertical swinging motions. The front end of the pitman 7c is fashioned into a link-head, l, formed with an upper and lower link, on and n, the former of which embraces at all times a lateral stud, 0, projecting from the adjacent side of the upper end of the bar or tool 0, while the lower link 02. operates in connection with a second lateral stud, 0, projecting from the opposite side of the tool 0 to embrace, when lowered, said stud 0, and when elevated to be removed from contact therewith. Upon the opposite side of the carriage d I form or apply a fork or recessed plate, 1;, the opening q of which expands at its upper part, while in front of this fork I pivot, by a stud or jourrial, a, to the front end of the beam G, the front extremity of an arm, q, the rear extremity of such arm bearing a lateral stud, 1', which coincides with and enters, when depressed, the fork p, and either locks the carriage d to the beam G or compels it to reciprocate in very short movements thereupon, according to which part of the flaring recess 1 the stud remains in, the pivot of the arm q being provided with a knob or handle, 8, by which the operator may'instantly and readily elevate or depress its free end, and thus adjust the position of the carriage 01 upon the beam G. In order that, with the descent of the arm q in the act of partially or entirely locking the carriage d to the beam Gr, as last stated, the link a shall be elevated from contact with the stud 0, and thus permit the vibration of the lever 0 through the agency of the pitman k to reciprocate the said carriage 01 upon the beam G, I make use of the following compound-lever motion-that is to say, I affix to the outer end of the stud a an upright arm, t, to the upper end of which arm I pivot one extremity of a pitman, u, the opposite termination of which is pivoted to the lower end of an arm, 0;, which is affixed to and depends from a horizontal transverse rockshaft, w, mounted in the upper part of an upright post, or, erected upon the beam G at about its center, while to the opposite end of such rock-shaft I affix a horizontal arm, 3 to the rear or free end of which arm I pivot the upper extremity of an upright link or pitman, z, the lower end of this pitman 2 being pivoted to the pitman is, before named, at about the center of the latter.

The above constitutes the mechanical elements of a machine for carrying out in one manner the purpose of these improvements. The variable transverse movements of the jack are for the purposes, as before stated, of advancin g the work to the burnishiug-tool, while the longitudinal and vertical freedom of motion of the standard a and beam G are for the purpose of presenting the burnishing-tool to the sole-edge and compelling such toolto travel about the entire circumference of such sole or of the heel, the motions of the burnishing-tool, whether vibratory, reciprocating, or compound, acting upon the leather with the proper polishin g action.

If desirable, however, may be imparted to the beam the lateral motions G in lieu of the jack, and the latter swing backward and forward; and for this purpose the arm G may be applied to the standard E by means of a balland-socket or other joint.

The operation of the details of mechanism which connect with and actuate theburnishin g is as'follows: If the operator desires a vibratory or compound motion of the burnishingtool he seizes the knob s, and, by means of it, depresses the arm q and lowers the stud 1' of the latter into the flaring opening q of the forked or recessed plate 19' before named as constituting part of the carriage 01, thus locking the said carriage rigidly to the beam G, or allowing it to reciprocate thereupon with very short reciprocations, according to the depth with which the stud r enters the opening q, it being understood that such stud is of a size to entirely fill the lower termination of said opening in order to effect the said rigid connection. Simultaneously with the descent of the arm q and the partial or entire locking of the carriage d to the beam Gr, as last stated, the head of the pitman 7c is elevated and its link or notch or removed from contact with the stud 0, this elevation of the pitman being effected by the arm t, pitman to, arm 0), shaft w, arm y, pitmen z and k, and lever e, hereinbefore explained, in manner as will at once be apparent to the observer. If a reciprocating motion of the burnishing-tool to and fro of the beam G is desired the operator has only to remove the motion of the knob or handle 8, which has the effect, through the agency above named, of freeing the arm q from the carriage d, thus allowin g the latter to slide upon the beam Gr, and, at the same time, of depressing the pitmanhead I and compelling it to embrace tightly both studs 0 0 of the tool 0, by this means locking the latter rigidly to the carriage and forcing it to travel with it, as, by this depression of the pitman-head, the oscillating-link motion becomes, by the change of position of the arm q, transformed into a rigid connection, which, as stated, compels the carriage, freed from the control of such arm, (which confined it to the beam,) to traverse the latter with intermittent reciprocations.

The burnishing-tool 0 can be made in various forms-as, for instance, present general shape,

both its ends, in its may be wrought into the desired polishing-surface or it may be a many-sided block, bearing upon one or all its faces the desired configuration in varied sizes or character.

I do not, in any sense, limit myself to the herein-described details of mechanism for imparting the desired motions to the burnishingtool, as these may be varied to a very great extent by any good mechanic without departing from what I believe to be the novel features in myinvention, which is the employment, in a machine for traversing and polishing the edge of boot and shoe soles, of atool to which reciprocating, vibratory, or compound motions may be imparted.

I therefore claim as of my exclusive invention the following, to wit:

1. In; machinery for traversing and burnishing or setting the edges of boot and shoe soles, a burnishing or setting tool to which reciprocating, vibratory, or compound motions are imparted, substantially in manner and to produce results herein stated.

2. The combination, with the boot support or jack for holdingthe work and presentin git to the burnisher, of a burnishing-tool carried by a flexible or jointed frame, and arranged and operated so as to have imparted to it reciprocating, vibratory, or compound motions, substantially as and for the purposes herein shown and described.

3. In machinery for burnishing sole-edges, the combination, with the burnishing-tool, whereby the movement of said tool may be changed expeditiously from a vibratory to a reciprocating motion, or vice versa, as set forth.

4. The combination of the beam G, carriage d, tool 0, pitman k with its head 6 fashioned as stated, and the arm q, the arrangement and operation of such parts being substantially as hereinbefore stated.

5. In combination, the standard E, beam G, carriage d, and the pitman k, and arm q, or their equivalents, essentially as and for the purposes stated.
