IMPROVEMENT IN SPOKESHAVES.

Specification forming part of Letters Patent No. 33,589, dated October 29, 186i.

To @ZZ whom it may concern.:

Be it known that I, J OH JENNINGs, Jr., of Natick, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Heel or Spoke Shaves; and I do hereby declare the same to be fully described and represented in the following specification and the accompanying drawin which case, after awhile, the reception-holes become so much worn as to render it difficult to preserve the cutting-edge of the knife at its proper or desi rable distance from the throat-piece b.

In making the stock I not only construct it with two tang-holes c c, but through each tanghole, and so as todiverge in opposite directions from it and parallel or about so to the rear side of the stock, I run or make asaw-kerf or long slit d, the same being as represented in the figures. A screw e is passed transversely through each of the said kerfs, and is screwed into that part of the stock which is in front of the kerf. Consequently when the screw is turned up so as to force its head against the stock the wood thereof will be so sprung that a firm grasp on the adjacent knife-tang may be secured. Thus as the tang-hole may become worn by movements of the tang produced by the occasional adjustment of the knife I have a means of adjusting the tanghole or rendering it smaller.

I do not claim the application of either wedges or metallic clamps to the stock and the fangs of 'the knife in order to fasten the said fangs in place in the stock. My improvement has advantages oversuch, and, besides, it materially cheapens the construction of a heel or spoke shave.

I am aware that it is not new to confine the tangs of a spokeshave in place in the stock by means of screws passing transversely into metallic projections extended from the stock, the ends ot' such screws bearing directly against the tang's extending longitudinally through such projections. Therefore I do not claim the broad ground of confining the tangs in the stock by means of screws; but

I claim- The improved stock as made with kerfs d d, arranged wit-hin it and with respect to its tang-holes c c and to receive screws, substantially in manner and for the purpose as specified.

JOHN JENNINGS, JR.
