WHETSTONE-HOLDEf-l.
SPECIFICATION forming pari; of Letters Patent No. 368,107I dated August 9, 1887.
Application filed February 2, 1887. Serial No. 226,265. (No model.)
To all whom it may concern) Be it known that I, DE FoREsT PARKER,
of Akron, in the county of Summit and Stateof iOhio, have invented certain new and useful Improvements in Whetstone-Hold'ers; and I do hereby declare the following to. be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it pertains to make and use the same. My invention relates to improvements in whetstoneholders; and it consists in certain features of construction and in combination of parts, hereinafter described, and pointed out in the claim.
' In the accompanying drawings, Figure 1 is a side elevation, partly in section, and Fig. 2 a bottom plan, of a whetstone-holder embodying my invention. Fig. 3 is a side elevation showing keys at both ends of the whetstone.
A represents the whetstone, and B the holder, the latter being of wood,with handles b at the respective ends. A metal plug, C, with a broad dat surface, forms an abutment for one end of the whetstone. this plug extends through the holder and is secured by a nut, c', This shank is of considerable length and has a handle, G, mounted thereon. The nut c may be set in the handle C', so that by turning the latter both the plug and handle C are tightened. At the other end of the whetstone is a key, D. This key has a tapering or wedge-shaped shank, D', that is set in a corresponding mortise made through the holder, and is secured by a thumbnut, E. The taper of this shank is on the outer edgethat is, opposite the whetstone-the incline being more abrupt at and near the under side of the holder, as shown at d in Fig. 1.
By tightening the thumb-nut E, and conse- 40 quently drawing in the key, the latter, by
The shank'c of reason of the wedge shape or incline d, is forced against the end of the whetstone, clamping the lal ter between the key and plug C, and by reason of the abrupt portion of the incline aforesaid and of the shank D approximately fitting the mortise and the nut,thus forming a fulcrum at this point, the lower end of the key is pressed more rmly against the whetstone, thus securing a firm hold on the stone and avoiding the crushing of the edge ofthe stone.
By loosening the key a trilie the stone may be removed in a moment and may be replaced and secured with equal dispatch. As the device is used largely for sharpening reapersickles,the handle C is convenient and allows the one hand that is liable to be injured by contact with the blade to remain out of danger.
Keys D may be used at each end of the stone, as shown in Fig. 3, with this advantage, that as the stones sometimes vary somewhat in length the two keys will accommodate a great range of stones.
What I claim is- In a whetstone holder, the combination,
with a bar having an opening through the same, one wall of said opening beinginclined, of a stop secured to the bar and adapted to engage one end of the stone, a key engaging the other end of the stone and provided with an inclined face adapted to rest in contact with the inclined wall of the opening, and a nut for moving the key, substantially as set forth.
In testimony whereof I sign this specitication, in the presence of two witnesses, this 12th day of January, 1887.
DE FOREST PARKER.
