IMPROVEMENT IN GUiDES FOR SAWlNG-MACHINES.

Specification forming part of Letters Patent N o. 176,565, dated April 25, 1876; application tiled February 21, 1876.

To all whom it may concern:

Be it known that we, HARRISON P. TAYLOR, FRANKLIN A. PERDUE, and JEREMTAH M. PERDUE, of Minerva, in the county of Stark and State of Ohio, have invented a new and useful Improvement in Guides for Sawing- Machines, of which the following is avspecication:

Figure 1 is a top View of our improved guide. Fig. 2 is a longitudinal section of the same, taken through the line w 5c, Fig. 1.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved guide for sawing-machines, planers, Snc., which may be adjusted to varyr the width, the bevel, or the taper ot' the work, and which shall be simple in construction and convent ent in use, and may be quickly and accurately adjusted without the 'use of a rule, square, line, or gage.

The invention will rst be described in connection with drawing, and then pointed out in the claim.

A is a plate, which is let into and attached to the table so that its face may be Hush with the surface of said table. In the plate A is formed a dovetailed groove or a plain slide, to receivea sliding piece,B,which is provided with a setscrew, b', to secure it in place when adjusted. To the forward part of the sliding piece B is pivoted thelower or horizontal arm of abracket, O, near its angle. The rear-end of the horizontal arm of the bracket C has a curved slot, c1, formed in it to receive a clamping-screw, c2, which screws into the sliding piece B, to clamp the said bracket C in place when adjusted. The upright arm of the bracket inclines to the rearward, and is slotted longitudinally, to receive the quadrant shaped plate D, the lower part of which is pivoted to and between the lower parts of the said slotted arm. The upper part of the plate D has a curved slot, d1, formed in it, to receive the clamping'screw d2, which passes through the upper parts ot' the slotted arm of the bracket G. Upon the forward edge of the quadrantshaped plate l) is formed a plate, d3, the side edges of which are beveled to fit into the dovetailed groove in the guide-plate E, to hold the said plate E. The plate d3 is provided with a set screw, d4, to secure it in place when adjusted. The part of the guide-plate E in which is formed the seat for the plate d3 is made thicker at one edge than at the other, so thatthe face of the guide-plate E may be at an angle with the plate d3, as shown in Fig. 2. For ordinary squaring and beveling, the guide-plate E is used, with its thin edge downward; but, for acute beveling, it should be used with the thick edge downward. The edge of the bed-plate A and the curved edge of the quadrant-shaped plate D have scales of division-marks formed upon them, so that the adjustment can be niade with quickness and accuracy without the use of a rule, square, line, or gage.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- In planer-guides, the plate E connected with quadrant D, by a dovetailed plate, d3, on which the plate E slides, as shown and described, to enable the plate E to be reversed at the times and in the manner specified.
