UNITED STATES PATENT CEEIGEQ CHARLES R. ELMER, OF BRIDGETON, NEW JERSEY.

IMPROVED MlLLSTONE-PICK.

Specification forming part of Letters Patent N0. 51,030, dated November 21, 1865.

To all whom it may concern:

Be it known that I, CHARLES R. ELMER, ot' Bridgeton, Cumberland county, New Jersey, have invented an Improvement in Picks for Dressing Millstoues; and I do declare the following to be a full, clear, and exact description of the same, reference being hadto the accompanying drawings, and to the letters ot' reference marked thereon.

My invention consists ot' a metal head having certain lugs and a thumb-screw combined with a double-edgedcutter adapted to the head and screw, substantially as described hereinafter, the whole forming a cheap, simple, and elticient instrument for dressing millstones.

In order to enable others to make and use my invention, I will now proceed to describe its construction and operation.

On reference to the accompanying drawings, which form a part of this specication, Figure l is a perspective view ot' my improved millstone-pick, Fig. 2, a plan View; and Fig. 3 a section on the line 1,2, Fig. 1.

A is a metal block or head, which is secured to a handle, B, and t'i om one end of which eX- tends a projection, c, ofthe shape illustrated or of any other shape which may be deemed appropriate, as the main object of this portion otl the head is to increase its weight. The upper side of the head A is tlat, and near each edge is a lug or tlange, b, a steel plate or-cutter, C, (properly sharpened at the opposite ends,) resting on the Hat portion ot' the head, and fitting snugly between the said lug.

In the middle of the plate C is an elongated opening, D, of thcformpseen in Fig. 1, this opening being enlarged at a pointmidway between the opposite ends for receiving the stem e ot' the thumb-screw E, which screws into the head A, and the head c of which bears against the steel cutter G.

It will be observed that the cutter is held iirmly in itsplace by the screw E and the lugs b b, the screw sustaining the full force of the blow.

When one edge of the cutter becomes dull it can be readily detached and reground and as readily readjusted to the head, and when one end of the cutter has been worn away by repeated sharpeniugs it can be easily reversed and the opposite end used.

It will be evident that the instrument is of the most cheap and simple character, the head being a plain block oi' cast-iron, to which itis unnecessary to impart any finish.

I do not desire to cla-im the heada, as the same has been heretofore used; but

I claim as my invention and desire to secure by Letters Patent The head A, with its lugs b b and thumbscrew E, in combination with the cutter C, constructed and adapted for attachment and adjustment to the head and screw, substantially as described, for the purpose specitied.

In testimony whereotl l have signed my name to this specification in the presence of two subscribing witnesses.

CHAS. R. ELMER.
