fro ALL WHOM 1T MAY coNoERN;

362e it known that I, BROWN, of `@Bereinin the county. of Cuyahoga, and vState of Ohio, have invented 4certen'new and useful improvements in Rests for Grinding Tools; and I do hereby declare that the following is a full Vand complete description of the same, reference, being had to the accompanying drawings, making s part of this specification, in .which- I i Figure 1 is a to'p view of the rest. Figure 2i is a. bottom view of the same. Letters .of referencerefer to like partsinthe different views. y 4The rest consists of the central stein A, iig. 1,to the upper end of `which is mortised the curved arm B,

and aboutmidway down .are projected the arms Cf To' the latter arms are connected the adjustable sides D D.

by a pivoted-joint, E. The arms B are made to slide through the'sides Da mortise being beaten for that purpose, so that Ythe sides may be spread outward more orl lesa-as. indicated by the-dotted lines a, and for the purpose hereafter` shown'.y F is a draw-shave, or it may be4 any other tool of a similar shape, and is placed between the upper ends and upon the under sidejof the sides "D, and'secured to the stem by the hooks G.' The stems of the hooks pass upward 'through the sides, and each is 'provided'with avthread and ainger-nut, by the means of which the tool is firmly heldin place; also to assist inholding the tool whilel'being ground. Gains Vare out immediately under the hook, into which -the shank of the tool is placed, and thereby prevented from slipping away-'from the stone. I is a plane-iron, a chisel, or it may be any other tool ofl a like shape. This tool is placed on4 the under sid'e of the rest, and secured by a staple or yoke, 25 vThis staple passes up through. the rest, the ends of which are riveted to a cross-tie, c. 'In the eentrefof Ithe tie isa thumb-screw, c. The tool on being'slipped under the staple is then screwed tightly down upon'it, and is thereby held securely for the purpose of grinding. l 1

l Themanner oiunsing the rest is as follows: The draw-shave or other tool being properly secured to the adjustable sides, which, as'abovc stated, may be spread outward in order to adjust it toan implement of. any

length, the lower end ot the'rcst,which is provided with a'p'ointed stem, J, is allowed to-stand 'upon the framev or table o't' the stone, the distance from the 'stone being ydetermined ,by the degree of-,bevel to'be given the tool. It is then brought to the face ot' the stone, and is by `thismeans held'irmly and secu-rely to the grinding surface, and a true and 'uniform bevel given thereby to' the implement. When a chisehorv any other tool lof 'a similar nature, is. to be ground, it is placed 'in the yoke or staple b, and'is then adjusted tothe stone in the 4same manner as above described in reference -to the draw-shave. y

What l' claim as -my improvement, and desire to secure by Letters Patent, isv lThe stem A, adjustable sides D pivoted to the arms C, in combination with' the arm B, hooks G, and staple Efprovided with screws as and for the purpose set forth: I
