Letters Patent No. 99,466, dated February Al, 1870 IMPROVEMENT IN BOOT AND SHOE-SHAVES- The Schedule referred to in these Letters Patent and making part, of the same.

To all whom it may concern:

Be it known that I, SUMNER PACKARD, of Grafton, in the county of Worcester, and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Boot and Shoe-Shaves; and I do here'by declare that vthe following isla full, clear, and exact description of the same, reference being had to the accompanying drawings,'ibrrniug a part of this specification, in which- Figure l represents a bottom view of my improved boot and shoe-shave',

Figure 2 represents a top view of my improved boot and shoe-shave;

Figure 3 representsa front view of the same; and

' Figure 4 represents a transverse cent-ral section, online A B, fig. 2.

To enable those skilled in the art to which my invention belongs, to make and use the same, I 'will proceed to describe it more in detail.

The nat-ure of my invention consists,

First, in the combination, with the blade, of conicalpointed adjusting-screws, as hereafter explained. l

Second, iu the combination with the shanks of the blade, of holding-screws, arranged in the front of the handle, as hereinafter described.

Third, in the combination with the handle of the shave, of a guard-plate and blade, and devices for adj usting the same, as and for the purposes hereinafter explained. v

Fourth, the combination with the blade and handle, of a back rim, as and for the purposes stated.

In the drawings, the part, marked A is the handle, and B is the blade, inserted ina recess formed in the handle A, as indicated in the drawings.

'The shanks a., of the blade B, project out past the ends of the blade, and are then turned up, so as to tit slots in the handle A.

A rim, C, is formed at the back of the blade B, against which the latter rest, and conical-pointed screws, c, are arranged through said rim, with their conicalpoints passingover the reinforce or flange b, at the back of the blade B, in such a manner that when the screws c are run in, the blade lis forced down by the conical points pressing upon the reinforce l1.

In this way the blade B can be very nicely audaccurately adjusted, to remove any thickness of shaving desired, and when the screws vare once properly set they do notrequre to be changed when the blade B, is removed for sharpening, consequently no time is lost or taken up in readjusting the blade, as is the case with the shave as ordinarily constructed.

The blade is held securely in any adjusted position, by means of screws d, that pass through the handle A, from the front side, land press against the front of the Shanks a, as indicated by dotted lines in g. 2 of the drawings.

By arranging the holding-screwed so as to be inserted 'from the front of the handle, sufficient thick- -ness ,of metal is obtained to receive the entire length of the screw-threads, while at the same time the pressure is thrown against the shauks a, in such a manand said plate, is held in placeby a clamp-screw, f,

which passes through a transverse slot, c, in the handle A, and by loosening said screw f, the guard-plate E can readily be moved back, to compensate for the wearing away of the blade- B, as occasion may require, thus preserving their relative ,distance apart until the plate is completely worn out.

- Those skilled in the art will readily appreciate the practical importance aud`value of the conical-pointed adjusting-screws c, since they enable the operator to remove the blade for grinding or sharpening, and replace the 'same very quickly, in the exact position which it before occupied, so that it will cutthe same depth of shaving that it cut before it was'removed.

Any desired size-of pointed screws may be used for the purpose of adjusting the blade. i

-A small projection, a, is formed on the front ofthe rim C, for the purpose of giving the blade a central support, as shown in igs. l and 2.

The rim C also-protects and shields the blade B from liability of being rapped or thrown out of place, while, at the same time, it stiffens and strengthens the handle A, so that the' latter can be made much lighter than would otherwise be the case. v

Having described my improvements in boot and shoe-shares,

That I claimI therein as new, and of my invention, and desire to secure by Letters Patent, is

1. The conical-pointed adjusting-screws c c, substantially as and for the purposes set forth.

2. The arrangement, in the handle A, of the blade B, and the holding-screws d d, said. screws being inserted from the front of the handle, so as to press againstthe vShanks a, andl case the blade to take. a directbearing upon the handle, in the manner and for the purposes set forth.

3. A boot and'shoe-shave, composed of the handle A, blade B, guard-plate E, holding-screws d, and ad justing-screws f and c, said parts being arranged to operate as shown and set forth. I
