IMPROVEMENT IN GUIDES FOR CIRCULAR SAWS.

Specification forming part of Letters Patent No. 140,096, dated June 17, 1873; application filed May 24, 1873.

To all whom it may concern:

Be it known that I, SAMUEL TAYLOR, of OIamon, in the county of Penobscot and State of Maine, have invented certain new and useful Improvements in Guides for Circular Saws; and I do hereby declare that the following is a full, clear, and exact description thereof, that will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings and to the letters of reference marked thereon, which form a part of this specification, in which Figure 1 shows a side view; Fig. 2, a plan of ym device.

Same letters show like parts.

My invention is designed for application to circular saws and edgers, and consists of an arrangement of devices by which an anti-friction roll for assisting the lumber past the saw is made adjustable to the different widths of the lumber required. I am aware that the roll has been used before for this purpose, but I do not claim it broadly.

My devices for rendering it adjustable will be understood by reference to the drawing, in which a shows the saw-table, and b the saw.

At 0 is a stationary standard bearing my device, which consists of a plate, 01, in which slides a rod or bar, 0, having upon its end nearest the saw the friction-roll g. Pivoted to the rod or bar is a handle, h, one end of which is formed into a pawl, t", engaging the teeth of a rack, j, attached to the plate at, and kept down upon said rack by means of a spring, is. The teeth of the rack are so spaced that they hold the roll at regular distances from the saw, which distances are indicated by numerals upon the bar 6, and gage the width of the lumber.

My device, as will be seen, is simple, and the gage can be changed almost instantly, and the roll set to different distances. The spring-pawl and handle, being in one piece, enables the operator to disengage the pawl from the rack and push in or draw out the roll at one operation, while the gage upon the rod shows at a glance when the roll is in the proper position.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination of the roll g, sliding bar 0, spring-pawl and handle 11. i, and rack j, substantially as and for the withiudescribed purposes.

In testimony that I claim the foregoing I have hereunto set my hand this 21st day of May, 1873.

SAMUEL TAYLOR.
