UNITED STATES PATENT OFFICE.
MERTON E. DAVIS, OF FAYSTON, VERMONT.
SPECIFICATION forming part of Letters Patent No. 651,652, dated June 12, 1900. Application filed March '7, 1899. erial No. 708,157. (No model.)
To all whom, it may concern:
Be it known that I, MERTON E. DAVIS, a citizen of the United States, residing at North Fayston, in the county of Washington and State of Vermont, have invented certain new and useful Improvements in Saw-Guides, of which the following is a specification.
My invention relates particularly to guides adapted to be used in connection with circular saws; and its object is, among others, to to provide a guide which will steady the saw, preventinglateral vibration, bending, or dishing of the same without the danger of overheating the saw by the friction; and to this end it consists of the arrangement hereinafter described and claimed, and illustrated in the accompanying drawings, in which like letters refer to like parts in each figure thereof.
In the said drawings, Figure 1 is a horizontal medial section of an adjustable saw-guide embodying my invention, with the adjacent portions of the saw and saw-table shown detached. Fig. 2 is a side elevation of the same.
The rollers A are adapted to be located one on either side of the saw 0, near the periphery thereof and beneath the saw-table. They are journaled upon the stepped bolt 13, which has a head 13 at one end and a threaded portion 13 at the other, adapted to receive the nut D, by which it is secured to the arm E or E through the slot 6 therein, along which it may be moved for adjustment, the step on the inner end of the portion B abutting against the side of said arm, and thus preventing the roller from being pinched between the head 13 and the same and allowing space for the said roller to rotate freely upon the'bolt. The roller is so disposed that the portion nearest the saw is parallel with the side surface of the same, and its axis is disposed in a substantially-radial position, so that the said rollers when they come in contact with the revolving saw will rotate easily and with very slight friction upon the same. Each roller issupplied with oil or other lubricant through the channel 13 in the bolt. The arms E and E extend to a post or other part of the saw-table frame, the latter directly and the former describing a curve around the edge of the saw and resembling the letter J in shape.
What I claim is 1. In a saw-guide in the combination of the curved arms E, E, the stepped bolts D and rollers A, substantially as herein shown and described.
2. In a saw-guide in the combination of the arms E, E, bolts B, slots 6, e and rollers A, substantially as herein shown and described.
3. In a saw-guide in the combination of the rollers A, stepped bolts D, channels B slots e, e and arms E, E, substantially as herein shown and described.
.. Signed at Fayston, Vermont, this th day of February, 1899.
