' JOHN CARREER, OF REYNOLDS BRIDGE, CONNECTICUT.

KNIFE POLISHER AND GRINDER.

SPECIFICATION forming part of Letters Patent No. 265,577, dated October 10, 1882.

Application filed June 26, 1882.

To all whom it may concern:

Be it known that I, JOHN CARREER, of Reynolds Bridge, in the county of Litehfield and State'of Connecticut, have invented certain new and useful Improvements in Apparatus for Grinding and Polishing Knives; and I do hereby declare that the following isafull, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to machines for grinding and polishing knife-blades, and has for its object to provide a device that will lessen the labor and at the same time be simple, durable, inexpensive, and efficient.

To this end it consists in certain improvements in the construction and operation of the same. I

In the drawings, Figure l is a side view of the machine; Fig. 2, a veitical longitudinal sectional view thereof; Fig. 3, a vertical transverse section, and Fig. 4 a top view.

Referring by letter to the drawings, AA designate two horizontal base-pieces, by which the device may be secured to a table or stand in front of the grindstone or direct on the frame of the latter. They are provided at one of their ends with upright standards B B, near the tops ot'which are secured rearward-inclined guides or braces C C, having longitudinal slots D D, in which is adjustable, by means of setscrews E E and blocks F F, a bail-shaped cross rest or brace, G, as shown. The standards B B are provided with vertical slots H H, in which work -|-bloeks I I, havingsecured to their outer ends plates J J, provided with a horizontal extension, K, at their tops, which extends in the slots and embraces a groove, L, around the lower end of an upright lifting or adjusting (No model.)

turned up to the position shown in full lines,

Fig. 2. The face of the boxing Q, is provided with a plate, S, at its top. on which the blades are to be fastened to grind flat or concave, and below this with a plate, T, held in place by a transverse pin or bolt, U, on which the blade is to be secured to be ground full or convex.

The operation and advantages of my invention will be readily understood. The blades are secured on the boxing of the lever and the latter turned and held over to bring them in contact with the stone, as in dotted lines, Fig. 2. The lever is readily adjustable with respect to the stone,and its relative angle thereto can be regulated.

I claim and desire to secure by Letters Patcut-- The combination, with the base-pieces having the upright standards and inclined guidebraces provided with an adjustable cross rest or brace, the standards carrying vertical] y-adjustable bloeks connected by atransverse shaft, of the block having a bearing on and laterally movable on said shaft, provided with means for holding the knife-blades and adapted to be turned over and held against the grindstone, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in presence of two witnesses.

JOHN CARREER. Witnesses:
