IMPROVEMENT IN SIOKE-SHAVES.

TO ALL PERSONS TO WHOM THESE PRESENTS MAY COME:

Be it known that I, SETE' T. HU'ICIXINS, of North Anson, in the county of Somersen'and State of Maine, have invented a. new and useful Improvement in Heel or VSpoke-Shaves; and IV do hereby declare the sameto be fully described in' the following specification, and represented in the accompanying drawings, of which- Figure 1 is a top view,

Figure 2 a bottom view, and

Figure 3 a. side elevation of a spoke or heel-shave provided with my improvement.

In carrying out my invention, I not only make the adjustable throat-piece or gauge separate from two buttresses, so applied to the stock as to be capable of being moved or adjusted thereon, in order to properly adjust the throat-piece relatively to the knife or cutter, but I hinge the throat-piece to one ofthe said buttresses in a manner to enable the throat-piece to be turned aside or away from the knife, in order to allow the latter to be sharpened, as occasion may require; the adjusting abutments of the throat-piece remaining in the mean while undisturbed in their positions relatively tothe steek. After the sharpening of the knife may have been effected, the restoration of the-throat-piece to place against the abutment, away from which it was moved, can bev accomplished, by simply turning the throat-piece down thereupon.

In the drawings, A denotes the stock, made in the usu'al form, and having two handles a a.' B is the knifor cutter, fastened. in or to the stock, C is the gauge, and D E its' two adjustable'abutments, each of the latter being held to the stock by means of a clamp'screw, b, going through a slot made in such abutment; the same being so as to enable the distance of the gauge or throatpieee C from the cutting-edge of the knife to be either increased or diminished, as circumstances may require. The gauge C is hinged, at or near one extremity, to the abutment E, and at its other endit bears against the other abutment, which is formed with a shoulder or bearing-surface for the gauge to rest on. This application of the gauge enables it to be moved from the abut meut D into the position denoted by the dotted lines at C in fig. 3.

I do not claim merely applying the gauge to the stock, so as to be adjustable or capable of being'adj usted nearer to or further from the knife, in order to either increase or diminish the chip-throat or passage between the knife and the gauge; but

I. I do claim the combination of the separate abutmcnts D E, applied to the stock A, so as to be adjustable, in manner as described, with the gauge G hinged to one of such iabutments, and being separat-e from the other, and to operate with respect to it substantially as explained. i

, 2. I also claim the application of the gauge to its adjusting-devices, so as to he removable from them or either of them, and the knife, when thc means of the adjustment of the gauge is held stationary relatively to the stock, as described. l

I SETI-I T. HUTCHINS.
