@sind @twine SAMUEL KEEN, 0F EAST BRIDGEWATER, MASSAGHUSlC'lTS.
' Latas Patent No. 96,120, zml 00am 2o, 1869.
IMPROVED HEEL-CUTTING- MACHINE. E40- The Schedule referred to in these Letters Patent and making part of the same.
To all zqhom lit may concern Be it known that I, SAMUEL KERN, of East Bridge. water, in the county of Plymouth, and State of Massachusetts, have invented certain new and useful 1mprovements in Heel-Cutting Machines; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. A
The nature of my invention consists- First, in giving to the knife of 'a heel-cutting machine a motion tangential to the heel-pattern or guard, so that it will cutnaturally on the tangent line.
Second, in certain mechanical devices, which can lonly be understood by reference to the drawings and specification.
To enable others skilled iu the art to make and use my invention, I will proceed vto describe its construction and use.
'Drau-ings. Figure l represents a perspective view of my machine.
Figure 2 is au elevation, the shoe-holding part L L (fig. l) being removed, to show the other part more clearly.
Figure 3 shows the knife and handle..
Figure 4 is a section ofthe knife.`
l construct my machine as follows:
A B represent the base and standard, to which th other parts of the machine are attached.
C is a shaft or spindle, supported by the standard B, and operated by the hand-lever C.
To the shaft G, the cam D, the head-piece L of the jacking-device L1L2, and the heel-pattern or guard P,
' are att-ached, and are severally removable.
The cam D, the shape of which is more clearly'indcated in lig. 2, operating upon the projection l)3 of the lever Dl, fig. 2, acting through the lever D1, link D2, lever E, and knife-socket H, causes the knifeH1 to move up and down; that is, tangentially to the heelpattern P. I
As this tangential 'motion of the knife, caused by the cam D, is the essential feature of my invention, I wish to call especial attention to it.
If the heel-pattern P were round, there would be no need of this tangential motion of the knife H, for then the knife might be set in position, and it would cut perfectly well, but as the pattern P is not round, it is evident that if the knife is set so as to be tangent -to one part, as, for instance, the point 1), ng. 2, it would not be tangent to the point p', when that has revolved so as to come inv Contact with the edge of the knife.
By my device the knife moving tangentially up and down, as the case may be, at the same time it is heilig revolved, the resultant of these two motions will, if the cam D is arranged properly, be a line always tangent to the pattern; ill other words, the knife will always cnt at the best advantage.
M M is a screw, by means of -which the shoe is held in position.
P', on the pattern l,`serves as a guide and support for the front edge of the heel.
N is a small roller, hung eccentrically upon the bar N, and serves as a rest, to hold the toe of the shoe.
N being eccentric, by turning it,it can be made to suit the different style and sizes of boots and shoes.
The handle K of the knife H is 'made cam-shape, as shown at K2, figs. 2 and 3.
This foam-form part rests against the guide K, so that when it is desired to change the lateral position of the knife, to suit heels ofdiiferent thicknesses, it may be turned so as to vbring different parts to rest against the guide K1.
H2, gs. 3 and 4, is a lip, the upper end of which is sharpened.
This lip runs between the sole and upper, and serves as a guide to the knife, and at the same time outs o" the feather-edge. f
S is a spring, which sei-.ves to keep the knife in proper position.
When this machine is in use, the operator controls the motion of the knife somewhat by the handle K, by means of which the style 'of the heel may be varied.
The lever 1*),to which' the knife-socket H is attached, by means of the pin R, is provided with a number of holes, lr, r', 860'., so that the position of the knife may be changed to suit different-sized heels.
That I claim as my invention, and desire to secure by Letters Patent of the United States, is#- l. The reciprocating knife Hl, operated by the cam I), or its equivalent, substantially as described, and for the purpose set forth.
2. The combination and arrangement of the cam K2, the knife H, and the guard K1, substantially 'as described, and for the purpose set-forth.
3. The combination of the adjusting-cam N with the jacking-device L L1 L2, substantially as described, and for the purpose set forth. v
