UNITED STATES PATENT OFFICE.
JOHN H. JACOBS, OF MARQUETTE, MICHIGAN.
S AW-BLADE FOR STONE-SAWING MACHINES.
SPECIFICATION forming part of Letters Patent No. 428,395, dated May 20, 1890. Application filed February 21, 1889, Serial No. 300,730 (No model.)
To all whom it may concern.-
Be it known that I, JOHN H. JACOBS, a citizen of the United States, residing at Marquette, in the county of Marquette and State of Michigan, have invented certain new'and usefulImprovemen ts in Saw-Blades for Stone- Sawing Machines and I do declare the follow ing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon, which form a part of this specification. 4
The figure of the drawing represents a side view of the device.
This invention relates to a new saw-blade to be used in stone-sawing machines. The saw-blades of these machines have notches in their cutting-edge, so as to form teeth. By constant use these teeth are worn down and the notches disappear. New teeth then have to be made.
The object of this invention is to produce a blade which will keep itself always sharpened, and in which as fast as one set of teeth are ground oif another set takes their place.
The invention consists in the construction hereinafter pointed out.
In the annexed drawing the letter A indicates a saw-blade having in its working-edge a the notches a. Above these notches is a line B of holes 1); above these other lines 0, D, E, F, G, H, and I of holes 0, (Z, e,f, g, h, and i. There may be only two or three of these lines of holes, or the blade maybe filled with them, as shown in the drawing; also, the top of the blade may have a line of notches m, so that the blade will be reversible. It will be seen that the lines are arranged so that the holes of the alternating lines are above each other, the other holes coming in between.
In making the lines of holes it is preferable that the bottoms of the holes of one line should be on a line with the tops of those be low, the bottoms of the holes b being on a line with the top of the notches a. By this 0011- struction, just as one set of notches disappears another set is made. It is also preferable that the notches and the holes should have their vertical axes longer than their transverse axes. By this construction sufficient width is given the notch to form the teeth, and at the same time the teeth are deeper, and therefore last longer.
Having described my invention, What I claim is- 1. A saw-blade for stone-cutting saws, provided with notches on its edge, and back of these notches with one row or more of holes. the lower ends of the holes of one row being on a line with the tops of the notches or the holes of the row beneath, as set forth.
2. A saw-blade for stone-cutting saws, provided with notches on its edges, and back of these notches with one row or more of holes, the lower ends of the holes of one row being on a line with the tops of the notches or the holes of the row beneath, the notches and holes being longer vertically than transversely, as set forth.
In testimony whereof I affix my signature in presence of two witnesses.
JOHN H. JACOBS.
