GAGE FOR WOOD-SAWING MACHINES.

SPECIFICATION forming part of Letters Patent No. 556,658, dated March 17, 1896.

Application filed November 30,1895. Serial No. 570,721. (No model.)

To @ZZ whom t may concern:

Be it known that I, JOHN BARNES, a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Gages for Vood-Sawing Machines, of Which the following is a specification.

The object of this invention is to provide a gage for Wood-sawing machines by thc employment of which the material to be cut can be iirnily clamped in position and tivo por tions nailed together without removing them from the gage.

In the accompanying drawings, Figure 1 is an isometrical representation of a saw-table top with my improved gage in position. Fig. 2 is a plan view of the gage. Fig. 3 is a vertical section on dotted line a, Fig. 2.

The table-top 1 is of the ordinary construction provided with an opening for the rotary saw 2, and having a groove 3 extending from the front of the table to its rear edge.

My improved gage consists of a circular plate in two sections 4 and 5, separated a proper distance to permit the passage of the saw, and having their rear ends connected by a bridge 6, therebyholding the sections firmly together. The outer edge 7 of the sections is beveled under and each section has a concentric groove S, the outer edge of which is cut under.

To the under face of the section -lis secured a guide 9 iitted to move in the guide-groove 3 in the upper face of the table. A handle 10 secured to the bridge 6 forms the means by which the gage may be moved bodily across the table.

To each of the sections is secured an ad j ustable support against which the material to be out is placed and an adjustable clamp for holding the material against the support.

The support consists of an edge bar 11, to which is secured the strip 12. From the edge bar extends an end portion 13, and a branch 1-1, connected to the end portion, extends radially toward the center of the sections. The end bar has tivo depending projections 15, having their faces beveled to correspond to the beveled outer edge of sections. A clampingbolt has one end, 1G, in hook form which engages the outer undercut edge of the concentric groove S. A screw-threaded shank 17 passes through one opening in the end portion 1S, receiving a thumb-nut 18 on its end 5 5 by means oi which the clamping-bolt and projections 15 engage the section, and byloosen` ing the thumb-nut the support is free to be moved in its engagement with its section. The outer strip 12 Will always extend in a 6o radial direction.

The clamps are of the same general construction as the supports, consisting of a base 19, from the inner end of which rise two ears 20, and from the outer end rises a perforated 65 ear 21, and at either side of the ear 21 extend projections 22, having their inner faces beveled and lying in contact with the outer undercut edge of the section. A clamp-bolt 23 has a hooked inner end which engages the 7o beveled outer edge of the concentric groove S, and has a screw-threaded extension 24 passing through the perforated ear 21, receiving a thumb-nut 25 on its outer end. The under face of the base 19 has a vertical opening and 7 5 a countersunk under face, Within Which is located a headed shank 26, having a horizontal screw-threaded opening, Within which is located a screwr 27.

By means of the thumb-nut 25 the clamp 8o may be loosened and adjusted in connection with its support, and when adjusted may be clamped in position.

The material to be operated upon is placed against the face of the strip 12 and the clamp 8 5 moved near it. The screw 27is turned against the material, clamping it against the strip. The gage is then moved in its connection With the table-top toward the saw, when the material Will be cut off at the required angle. If 9o both supports are adjusted so as to form a right angle of the strips 12 and the material clamped in position after being cut, they can be moved against each other and firmly held, and in such position can be nailed or fastened 95 together as in the manufacture of picture frames.

I claim as my invention 1. In a sawing-machine the combination of a table-top, a rotatable saw, a gage consisting roo of two plates, a bridge connecting the plates at one end permitting the passage of the saw,

the plates having a ymovable connection with the table-top toward and from the saw and strips having a connection with the plates.

2. In a gage, the combination of a tabletop, two semicircular plates, a bridge connectin g the plates at one end the plates guided in connection with the tabletop, a strip for each plate having an adjustable connection therewith, the connection consisting of a base-plate having one end engaging the under-face beveled edge of the plates, a clamping-bolt, having a hooked end located in a concentric groove formed in the plates, and means for forming a connection between the clamping-bolt and base.

3. In a sawing-machine the combination of -a table-top, a rotatable saw, a gage consisting of two plates, a bridge connecting the plates at one end permitting the passage of the saw, the plates having a movable connection with the table top toward and from the saw, strips having a connection with the plates and clamps for holding the material to be operated upon against the strips having an adjustable connection with the plates toward and from the strips.

4. In a gage, the combination of a tabletop, two semicircular plates, a bridge connecting the plates at one endand guided in connection with the table-top, strips having a connection with the plates, a clamp for each plate having an adjustable connection therewith, the connection consisting of a base plate having one end engaging the under-face beveled edge of the plates, a clamping-bolt having a hooked end located in a concentric groove formed in the plates, means for form ing a connection between the clamping-bolt and base, and a swiveled screw having a connection with the base.

5. In a sawing-machine, the combination of a table-top, a rotatable saw, a gage consisting of two plates, a bridge connecting the plates at one end permitting the passage of the saw. the plates having a movable connection with the table-top,strips having an adjustable connection with the plates, and clamps for holding the material to be operated upon against the strips made adjustable in connection with the plates.

6. In a gage, the combination of a tabletop, two semicircular plates movable in connection with the table-top, a-strip and clamp for each plate having an adjustable conne@ tion therewith the connection consisting of a base-plate having one end engaging the under-face beveled edge of the plates and a clamping-bolt having a hooked end located in a concentric groove formed in the plates. and means for forming a connection between the clamping-bolt and base, the clamp havin a swiveled screw.
