Diamond-Saw for Cutting Stone.
Patented Oct. 11, 1875.
I v M 22% UNITED STATES PATENT OFFICE.
HENRY RUNG, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF HIS RIGHT TO ROBERT BAUMGARTEN, OF SAME PLACE.
IMPROVEMENT IN DIAMOND-SAWS FOR CUTTING STONE.
Specification forming part of Letters Patent No. 168,786, dated October 11, 1875; application filed August 10, 1875.
To all whom it may concern:
Be it known that I, HENRY HUNG, of Chicago, in the county of (look and State of Illinois, have invented an Improvement in Diamond-Saws for Out-ting Stone, of which the following is a specification:
The nature of my invention relates to an improvementin stone-saws ofthat class wherein carbon points are secured to one edge of theblade to serve as cutters; and its object is to afford a means for readily and firmly securing the carbon points in position.
The invention consists in a saw-blade made or built up of two thin strips with spacerblocks riveted between them, each having a socket in an outer corner to receive one corner of the carbon point, which is held therein by a gib pressed against the other by a wedgeshaped key, as more fully hereinafter set forth.
Figure 1 is a perspective view of my saw. Fig. 2 is a longitudinal section.
In the drawing, A represents the saw-blade, built up of thin strips of steel, with spacerblocks B riveted between'the blades wherever a carbon point is to be inserted. In the outer corner a half-dovetail notch is cut to receive the base of a prismatic point, a, which is held in place by the corner of a gib, O, inserted from the back of the saw, and which gib is filed to fit and embrace the projecting corner of the point a, the gib being forced against it by a wedge-shaped key, D, driven between it and the next spacer-block.
The carbon points need not necessarily be uniform in size and shape, as heretofore, as the gib corner can be filed to tit accurately an uneven or odd-shaped point that is to be se- HENRY HUNG.
