SPECIFICATION forming part of Letters Patent N0. 260,828, dated July 11, 1882.

I Application filed January 9, 1882. (No model.)

To all whom it may concern:

Be it known that I CALEB J. BLAKELY, of Janesville, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Boot and Shoe Burnishin g 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'itpertains to make and use the same." 77 V,

My invention relates to an improvement in boot and shoe burnishing machines; and it consists in the novel manner of constructing the burnishing-tools and holders, and the manner of operating and limiting the movement of the same with respect to the boot or shoe, which latter is-held against the burnishing-tools by the operator.

- In the accompanying drawings, Figure 1 represents a perspective view of my improved machine. Fig. 2 is a side view of the same.

, Fig. 3 is a detached view ofthe tool-holder.

Fig. 4 is a detached view of the top-lift burnisher. Fig.5 is a vertical section through the cam-wheel and pin, and Fig. 6is avertical sectionalview 'ot' the edge-'burnisher with its attachment.

A represents the bas'eof the machine, provided at its rear end with the standards B, which latter are recessed at their upper ends for the reception of the two part bearings G.

' These two=part bearin gs (J are held in place by the caps a, and are adapted to support the driving-shaft D, which latter is provided between the standards B with the loose pulley E, on which the driving-belt moves when the machine is at rest, and with the rigid pulley E, on which the belt moves to impart a rotary motion to the brush F and a reciprocating motion to the burnisher. This brush F is situated near one end of the driving-shaft D,just behind the cam-wheel G, and is adapted to remove corrosiveinksremaining on the sole. The cam-wheel, as before stated, is secured to the outer end of the driving-shaft D, and is provided with a movable crank'pin, H, to which the pitm an 1 is connected. If this crank-pin H were rigidly securedto thecam-wheelG,thelength ofthe'stroke of thetool-holder J would always be the same,

and to remedy thisdefectlhave provided means whereby the length of the stroke of the toolholder and burnisher can be increased or diminished so as to suit the different kinds of work capable of being performed on this machine.v Thus, forinstance,the shank-burnisher must be operated with a shorter stroke than the top-lift burnisher, and different sizes of heels necessarily require difierent lengths of stroke. To produce this variable stroke I have providedthe cam-wheel G with a T- shaped groove, K, running centrally through the same, in which the crank-pin H can be removably secured at any point from the center to the periphery of the same, thereby regulating the stroke, from the smallest possible one to the largest one, which is dependent on the diameter of the cam-wheel. The crankpin H is provided with a T-shaped head,'b, adapted to fit in the T-shaped groove K, which prevents it from turning while the shank thereof is rounded, and provided with a screw-threaded end, by which the pitman I is secured thereto. 7 This crank-pin H is also provided with the removable sleeve L, which'latter is adapted to form the bearing for the pit- 7 5 man I; This sleeve is also provided with the enlarged ringor collarc,adaptedto bear against the outerside of the pitman. To adjust the length of the stroke it is necessary to loosen or remove the nut 61 on the endot' the crankpin, which loosens the parts and allows the said crank-pin to be moved toward the center or toward the periphery, as the case may be. When the proper position that will give the desired stroke has been reached the nut d is again screwed uptight, which forces the crank-pin H outward and the sleeve L and collar 0 inward, and causes them to clamp that portion of the cam-wheel between them firmly which holds the parts in position. c

The opening (2 in the end of the pitman Ii'or the reception of the crank-pin H is provided with the annular split collar or bearing-ring by means of which, together with the screw 9 in the end of the said pitm an, thewear is taken 9 5 up, which prevents any loss of movement, as Well as the waste of any power. The opposite end of the pitman I is connected to the slide M, which latter has the tool-holder J removaand on its under surface with a V-shaped ten on, h. The slide M is adapted to move on this slide-bearing N, and is provided with the two lateral extensions 11 and z, the lower one being provided with a V-shaped groove or mortise, h, in which the V-shaped tenon on the slide is guided, while the upper extension is provided with a downwardly-projectin g flange, P, which, together with its connected parts, is adapted to receive and retain the adjustable bearing-piece Q. This bearing-piece Q is provided with a V-shaped tenon, h, adapted to rest in the groove h, and is heldin position by the screws Z and Z, adaptedto bear against its side and top, respectively. When this part Q becomes worn the screws 1 are loosened and the screws Z driven farther in, which forces the piece Q to its proper position on the slidehearin g, when the screws lare again tightened, which holds the said piece firmly in such position. The slide M is provided on its outer side above the pitman-connection with an inclined lip m, adapted to afford bearin g and means of attachment for the tool-holder J. This tool-holder J is provided atits lower end with screw-holes for its attachment to the lip m, and at its upper end with the arms J, between which the burnishing-tools are adapted to be secured. The slot J between the arms J is suflicientl y long to allow the arms a slight spring, which is necessary to securely fasten the holders therein.

The top-lift burnisher R is curved, substantially as shown in the drawings, and is provided with the shank R, havingthehole ntherein, through which the bolt S passes. This shank R is placed between the arms J, and the boltS passed through suitable openings in the upper ends of the arms J and through the opening in the shank, where it is secured in any desired position and inclination by the thumb-nut T. This burnisher R is hollow, and is heated by gas conveyed to the same through the flexible pipe T.

The shank-burnisher shown in Fig. 6 of the drawings is provided with the attachment U, by which it is secured between the arms J, precisely like the top-lif t burnisher, already referred to. The head U of the attachment is provided with the openin g p,extendin gthrough the same, into which one end of the screw 1) is adapted to project more or less and restrict the opening at that point. The shank of the burnisher b is provided with the rectangular cut-away portion 1', into which the end of the screw 12 projects and prevents the said burnisher from being withdrawn from its attachment. That portion of the shank of the burnisher between the head of the attachment and the shoulders s is surrounded by the spiral spring W, adapted to allow the burnisher to The burnisher can be heated by gas In using this machine to burnish boots or shoes the operator stands to the side of the machine and holds the portion thereof being burnished against the burnisher, which is reciprocated over it. If desired, another burnisher, with its connected parts,can be secured to the opposite side of the machine and connected with a cam-wheel on-the opposite end of the shaft D, thereby enabling a shank-burnisher to be operated on one side and a toplit't burnisher on the other side, or two top-lift burnishers to two shank-bunishers on the one machine. Itis also evident that a tool to burnish the entire shank or for setting the edges can be used in connection with this machine, and hence I would have it understood that I do not limit myself to the exact construction ot'parts shown and described, but consider myself at liberty to make such changes as come within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, isv 1.
