GEORGE E. WOOLSTON, OF DISTRICT OF ORANGEBURG, SOUTH CAROLINA.

SAW FOR SAWING AND SMOOTI-IING BOARDS.

Specification of Letters Patent No. 8,393, dated September 30, 1851.

To all whom it may concern Be it known that I, GEORGE F. WOOLSTON, of the district of Orangeburg and State of South Carolina, have invented a new Improvement in Teeth of' Saws, which is for the purpose of planing lumber in the operation of sawing, or producing a smoother sur face, so that it may be the more easily planed; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 represents a circular saw; B, teeth of the usual form for sawing; C, teeth formed with a groove in the underpart, so as to form double edged chisels;-having sharp edges at the sides for the purpose of planing; and may be set so as to cut slantwise. The planing teeth may be formed or set, by a process which will be understood by reference to Fig. 2, in which D represents a wedge, formed of parts D F and G, connectas represented by Fig. 4:, by being widened,

and having square edges at the sides. Incircular saws, to prevent back scratching, a thin circular plate may be attached to the saw, as represented by the line K; so as to be between the log and the saw blade.

I claim, for the purposes above set forth,.

Forming and arranging teeth of saws substantially as herein descrlbed.

GEORGE F. WOOLSTON.

Witnesses JOHN Lacuna, JAMES JONES.
