To aZZ whom it may concern.-

Be it known that I, GEORGE E. SMITH, a citizen of the United States, residing atExete r, in the county of Rockingham and State of New Hampshire, have invented certain new and useful Improvements in Burnishing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present improvements relate to burnishing machines for use in the manufacture of boots and shoes.

The object is to'simplify, cheapen and perfect the construction of machines of this class, and it therefore consists in the construction,

arrangement and combination of parts, substantially as will be hereinafter described and claimed.

In the accompanying drawings illustrating my invention, Figure 1 is a front perspective view of my improved burnishing machine. Fig. 2 is a rear perspective view of the same. Fig. 3 is an enlarged sectional plan view showing the mechanism for operat ingthe brush.

Fig. 4 is a vertical sectional view of the 1101-,

low standard or base and the interior mechanism which is shown in elevation. Fig. 5 is a detail sectional plan 'view showing the lever and other mechanism for shifting the rotary support which carries the jacking mechanism for the boots and shoes to be burnished. Fig. 6 is a cross section on line m :c of Fig. 5. Fig. 7 is a cross-section on line y y of Fig. 5. Fig. 8 is an enlarged sectional edge view of the devices whereby the tool carriers are gradually reciprocated during the operation of the machine. Fig. 9 is a cross section on the line .2 z of Fig. 8. Fig. 10 is a detail edge view of the horizontal bar which operates in conjunction with the upper portion of the devices shown in Fig.8. Fig ll is alongitudinal sectional view of one of the levers that compose the head of the machine. Fig. 12 is an enlarged sectional detail view of a portion of the clamping or jacking devices for holding the boot or shoe. Fig. 13 is a view of one of the outer heads or castings that supports one end of each of the several levers composing Fig. 14 is a view of the inner head or casting employed for supporting the other end of each of said levers. Fig. 15 is an edge view of the part shown in Fig. 14. Fig. 16 is a perspective View of a modified form of the jacking mechanism. Figs. 17, 18 and 19 represent a modified form of burnishing tool which may be employed.

Like letters of reference denote like parts in the differentfigures of the drawings.

A designates the main frame or standard of my improved burnishing machine, which frame or standard may obviously be constructed in any desired manner, having any suitable shape and proportions. It is prefer ably hollow to allow certain mechanical parts to be accommodated therein, and is provided with a side door A, to perniitof access to those parts.

At oneside of the lower portion of the bed or standard .A, is located a horizontal countershaft 13 supported horizontally in suitable hearings in the standard A and in a bracket B, on the side of said standard A, said counter-shaft B having thereon a fast and loose pulley B which is adapted to receive an actuating belt running from any suitable driving power, and said shaft B having also thereon the pulley 13 around which passes a belt which runs upward and around a loose pulley F on the shaft F belonging to the brush-operating mechanism and also around a pulley H on the shaft Hbelonging to the mechanism which operates the burnishing tools, both of said pulleys F and H being consequently driven by said belt.

The shaft F is supported in horizontal bearings ff, fastened rigidly onthe main standard A or formed as a part thereof. See Fig. 3. Parallel to the shaft F is another shaft 1, which carries at one end the brush I, said shaft I having one of its bearings in an upright casting I which is rigidly mounted upon the shaft F astride of the bearing f, all as clearly shown in Fig. 2, and said shaft I having another bearing near the brush 1 in a horizontal sleeve '5, which is pivotally supported in the bifurcated end of a rod J, that passes downward through a rightangled socket f fastened on the adjacent end of the shaft F, the lower end of rod J being enveloped by a spiral spring j which is tensi'oned between a collar on the end of rod J and the socket f The shaft I is made in two parts that are connected together at a point near the casting 1 by a knuckle or universal joint I in order that the brush-carrying end of the shaft I may have a certain freedom of movement laterally to the extent permitted by its connection with the spring-enveloped rod J. On the shaft F is a pulley F made fast with the loose pulley F and on the shaft I is a pulley I opposite to pulley F A belt passes around these two pulleys so that motion is communicated from loose pulley F to shaft I to drive brush 1. On the shaft F is a segment pinion E, see Fig. 2, seen-rely fixed thereon, which is engaged by a segment gear D carried on the end of lever D, which is fulcrumed on stud (Z projecting from part f, see Fig. 3, or some other suitable part of the frame. The opposite end of lever D, as will be seen by referring to Fig. 4, is located within the casing A, and ispivotally attached to theupper end of the connecting rod 0, whose lower end is connected to acrank pin onv the stud-mounted gear-wheel a, which meshes with a pinion b, on the counter-shaft B. By these connections between, the shaft F and the counter-shaft B, it will be seen that shaft F will be rocked alternately in one direction and then in another and this will take place simultaneously with the swift rotary motion imparted to brush 1" from the belt connections with shaft I. Securely attached to the shaft F at a point between the casting I and the segment pinion I is a counter-balancing weight F. The effect of alternately rocking shaft F will of course be to carry with it the parts that are firmly and rigidly attachedto it and since hearing I and socket f are thus attached the result will be to alternately transfer the shaft I from the position shown in Fig. 2 where it is vertically above the shaft F, to the position shown in Fig. 3, where it is horizontally opposite to it and also to such other positions as it might assume during the oscillations, depending of course upon the size of the segment gears. Pivotedon the socket f is a short lever g, one end of which is attached to the bifurcated upper end of shaft J, while the opposite end carries a weightG. This weight serves to balance the weight of shaft I and to keep the brush Ifrom dropping off the heel of shoe, when it is operating on the bottom thereof'and to sustainthe weight ofthe shaft and keep same from pressing on the shoe when on top. The weight F counterbalances the entire brush-operating mechanism and keeps its motion steady and uniform. The segment gear connections will cause the brush to run: back and forth. from one side of the heel to the other about sixty times per minute, while at the same time the brush is rotating about one thousand times per minute in consequence of the actuation of its shaft in the manner I have described.

The horizontal shaft H which we have seenhas thereon a drive pulley H is supported in suitable hearings in the base of a back box or by flanges on the wheel face.

handle and the thimble L standard K which is bolted to the top of pedestal A, said standard K being so recessed or otherwise box-shaped as to permit a vertical worm wheel L to be mounted therein on a stud as shownsee Figs. 1 and 8, said wormwheel being in engagement with and actuated by the worm H on shaft H. In the end of shaft H, opposite that which carries the pulley H, is an eccentric pin it which operates as a cam. This pin 72 is located within a vertical slot m in the lower end of a vertical lever M which is fulcrumed near its middle point upon a stud projecting horizontally from segment pinion M on the horizontal shaft N,

which is journaled in the upper ends of standards K and K and which carries the burnisher' mechanism. Thus it will be clearly seen that as the worm-shaft H revolves, the shaft N will be oscillated by the segment gearing, and the cam movement.

Alongside of the standard K and situated opposite to the internal worm wheel L is a parallel' vertical lever K which is supported at its lowerend on a stud at the bottom of standard K. See Figs. 1 and 8. The upper end of lever K is connected to a horizontal rod 0- see Fig. 10whic'h is attached by its angular semi-circular part, to the grooved casting P- see Figs. 14 and 15Which slides upon the shaft N and is a partof the burnisher operating mechanism. The connection between lever K and rod 0 is made by a bolt 0, passing through lever K into a split sleeve 0 which embraces rod 0 and is clamped thereto by a bolt and which slides into the upper end of standard K, through a suitably shaped opening provided therefor by the side of the bearing for shaft N, as shown in Fig.8. The fulcrum of the lever K is obviously at its lower end where it is pivoted upon the stud.

At a point opposite to the worm-wheel L the lever K is provided with a slot is.

See Figs. 1 and 8. On the face of the wheel L next to slot 7a, is a slot or uide-wa L across the center of the Wheel L, which is preferably formed This slot L receives the square head Z of a bolt L which passes loosely through a thimble L that is placed thereon, with a shoulder next to the worm wheel, as shown, said thimble being made as-a square block and being situated in 4 This block or thimble is adapted to slide back and forth in the slot ic. A handle L screws upon the end of bolt L and" a washer is interposed between the Thus there is a square block to slide in slot 7.: and a washer or shoulder on each side of said slot to keep 1 the block in place. volves, the thimble L will travel back and As the worm wheel L reforth in slot Zr, and this will oscillate lever K. If the head. Z of bolt L is at the center of wheel, then as worm wheel L rotates, lever K formed by the lugs 19, and the outer head Q from slipping.

will remain immovable and will not oscillate. If however we move head I along slot L a short distance from center of wheel L, then the thimble will travelin slot 7c and the lever will oscillate sufficiently to regulate to the desired degree the position of the burnisher mechanism. Thus by laying hold of handle L and properly adjusting the head Z, the burnisher mechanism can be adjusted to operate,

upon heels of any length, shape and size.

I will now describe the burnishing mechanism proper which is located at the top of the machine and which operates the burnishing tools. The shaft N has already been mentioned as being journaled in standards K and On this shaft are the two castings P and has the radial openings g. In the present example of my invention there are five levers R, but I do not wish to be restricted to .this number. Consequently the heads P andQ each have five slots in which the five levers R are supported in horizontal positions, as

shown in Figs. 1 and 2, the lever B being shown in detail in Fig. 11. The head Q is secured fast upon shaft N by means of a setscrew. See Fig. 13. The inner ends of levers R are perforated and connected by screws or bolts to the'lugs p on head P, which slide on shaft N. Thus it will be seen that the inner ends of the levers R are all connected together by the head P, while their forward ends are free to slide in the slots q of the head Q, whenever a longitudinal movement of the levers R occurs.

The levers R are all similarly constructed and arranged. See Fig. 11. The forward end is split and a screw-bolt serves to draw the halves tightly together so as to clamp, be-

tween them, the spindle of the tool-holder'R. This tool-holder may obviously be of any desired kind, and being supported as stated, it will be readily adjustable for any size and shape of heel. These tool holders R preferably have a pin in the center to keep the tool On the top of each lever Ris a small pulley r, which may be supported on a stud projecting from a lug on the lever as shown in Fig. 11. A cord, belt orstrap it, passes around all these pulleys r and also down over. the guide rollers and into the base A, where the two ends ofbelt'n are fastened to a clamp n' made preferably of two pieces with a cap screw in the center to hold them tightly In the bottom of base A is a horizontal lever T, which is hingedat one end to "be acted on by the buruishing tools.

the wall of base A and has its other end projecting through the opposite side of base A, see Fig. 1, and carrying an adjustable weight T. A connecting rod t connects the lever T with the clamp n. Thus the weight T acts to keep the belt n at the proper tension. This belt serves therefore as a pressure belt, giving the same pressure upon levers R for any size or shape of heel. To reduce or increase the pressure the weight T. may be adjusted upon the lever T.

The under side of levers R is cored out to receive a longitudinal portion of gas pipe R one end of which is bent and passes through the lever B so that a flexible tubing B may be connected thereto, while the other end enters a heat chamber R adjacent to the burnishing tool. This pipe is used only when necessary as the friction from the tool itself generally gives a good deal ofheat. The several rubber tubes R see Figs. 1 and 2, connect to a suitable gas cook R on the standard K whereby they are all supplied from some suitable source. Each lever B has a setscrew R near head P to adjust itself with y when large heels are being burnished so as to keep the tool from'closing down sufficiently far to prevent these large he'els'from entering the machine.

A variety of tools may be employed with the tool holders R and I do not wish to be restricted to any particular kind The tool maybe made like a spiral spring and formed around the heel as shown in Figs. 1 and 2. The wire employed for this purpose is preferably oval in cross section. With the wirein this shape a fine burnish is given to the heel with a light pressure. The wire is arranged to cover the heel entirely around it. I-Ience such a burnisher will operate very fast indeed as it has only to run the length of the heel from the top lift to the upper. Instead of the wire burnisher a cast iron or other metallic tool may be employed. An example of such a tool is shown in Figs. 17, 18 and 19. It has a wax chamber containinga supply of wax, a passage for delivering the wax to the heel and a set-screw to adjust the wax. Tools of this kind'are made rights and lofts.

The jack frame consists of a hub U provided with any suitable number of arms to (say four for example) which furnish rests at their ends for the bottoms of the shoe heels, and also with a similar number of jack arms U which carry the jacking or clamping devices for clamping the shoes firmly in position against the arms to where they can readily This jack frame has its hub U mounted on a shaft U on which it slides, said shaft projecting horizontally from one side of base A. See Fig. 5. A horizontal lever arm V which is pivoted at 1; within the base'A to the wall thereof, projects through the slot A near the top, of base A. This lever connects by a rod V with" the hub U. The operator therefore can by means of the lever V shift the hub U and con- ICO sequently the jack frame, back or forth upon the shaft U This shaft U has a certain number of splines thereon, say four for instance, and'these splines are entered by a pin or pins on the hub so that the hub cannot be rotated on shaft U except when it is at the outermost end thereof and farthest away from the burnisher mechanism. The jacking de-' vices at the end of each jack arm U are shown in detail in Fig. 12. They consist essentially of a segment gear W on the end of a pivoted arm W. This segment engages a rack to on a sleeve w which is split and furnished with a bolt to enable its halves to be drawn together so that it may serve as a clamp to securely hold within it the spindle W which enters the shoe and forces the heel against the arm 'u, as shown in Fig. 1, said end of the spindle W within the shoe, carrying a thimble with a spring herein so as to make it somewhat yielding to allow for the varying of the heel. Obviously the'spindle VV can by means of the sleeve w be set for any length of heel. On the side of each arm U adjoining the jacking devices is a catch device which projects beneath thelever W and holds the same in the position shown by dotted lines in Fig. 12. This-catch consists of asmall lever W which operates a pin that projects beneath lever l/V This lever has a spring that keeps it in such position that the pin is normally projected at all times. By pressing on the lever however, the pin is withdrawn so that the lever W can drop into the position shown in Fig. 12, which releases the spindle W- from the shoe and is what takes place in unjacking.

e0 denotes a rubber or elastic bumper for the lever W to strike when it falls so as to make no noise or jar. As the hub U is mounted on the spindle U as described, it can be readily removed therefrom. Thus the four arm jack can be taken off and one having more or less arms used when desired.

In Fig. 16, I have shown a jack having only two arms. This style of jack is used for wax and bright burnishing and is operated so that while one shoe is being burnished another will be brushed. When there are but two jack arms as in this case a weight, as for instance ball U is fixed below hub U, so as to keep the jack from burning.

Numerous changes in the details of con struction maybe made without varying from the claims.

Having thus described my invention, what I claim as new, and desire to secure Letters Patent, is-
