UNITED .STATEs PATENT OFFICE.
HERBERT COTTRELL, 0E NEWARK, NEW JERSEY.
IMPROVEMENT INSTONE-CUTTING TOOLS.
Specification forming part of Letters Patent No. 144,318, dated November 4, 1873; application filed August 21, 1873.
To all whom "it may concern:
Be it known that I, HERBERT OoTTRELL, of Newark, Essex county, New Jersey, have invented certain Improvements in Stone-Gutting Tools, of which the' following is a specification:
The tool in which my invention is comprised is designed principally to surface rough stones, or to cut a thin layer from the stone, so as to leave a smooth surface thereon. The cutter proper is a revolving circular disk, armed on its periphery with carbons or diamonds, which constitute the cutting-edge. With the revolving circular cutter is combined a stationary wedge or beveled disk, which lies on the upper or outer face of the circular cutter, with its periphery at a proper distance from the cutting-edge, and serves, when the tool is fed against the. stone, or vice versa, as a wedge to break off the portion of the stone left above or outside of the kerf cut by the diamond edge of the cutter. feature of my invention consists in this combination of a revolving circular diamondarmed cutter and a stationary wedge or beveled disk, the principal advantage derived being that, inasmuch as the wedge-disk, which forms part of the tool, is stationary, it is not acted on so injuriously by the grit of the stone, and is not rapidly worn out and ground away, as it would be were it to revolve with the cutter.
The nature of my invention, and the manner in which the same is or may be carried into effect, will be readily understood by reference to the accompanying drawing, in which Figure 1 is a perspective view of a tool made in accordance with my invention, and Fig. 2 is a longitudinal vertical section of the same.
The cutter proper consists of a circular metallic disk, A, armed on its periphery with carbons or diamonds, contained and held in steel sections a in the usual way, so as to 0011- stitute a cutting'edge. This disk is fixed to a revolving spindle designed to be supported in suitable bearings, and to be rotated at a high velocity. The disk can be secured to the spindle by being keyed thereto; or, what is preferable, it may be provided with a screw- The essenti althreaded hub, engaging and fitting the corre spondingly screw-threaded end of the spindle. The cutter-disk is also preferably made concave, as shown; since, with that form, it can more readily clear itself, and more freely admit the supply of water. To the outer face of the revolving cutter is applied the wedge or beveled disk 0, which is fixed to and supported by a hub fast to the front bearing of the spindle B. This wedgedisk is, consequently, stationary. It is made of metal, and is in contact, or very nearly so, with the cutter. It tapers or is beveled in such manner that its exterior edge or periphery is of little thickness, and does not project so as to have more thickness than the kerf cut by the diamondcdged cutter. It will be understood that the tool can be either fed against the stone or the stone can be fed against the tool, as is customary in like cases.
The operation is as follows: The diamondarmed sections attached to the periphery of the revolving circular cutter-disk cut into the stone, the kerf being made by the carbons or diamonds held in said sections. Further progress forces the stationary beveled disk into the kerf, and this disk operates as a wedge to divide the stone by breaking off the portion left above or outside the kerf. Thus, in surfacing stone, but a small portion is ground to powder, the bulk of the rough portion being, by the action of the wedge-disk, thrown off in the form of chips. This wedge-disk, being stationary, is not rapidly ground and worn away and destroyed, as it inevitably would be were it to revolve with the cutter.
What I claim, and desire to secure by Letters Patent, is
The combination of a revolving diamond or carbon armed circular cutter and a stationary wedge or beveled disk applied to and operating in-connection with said cutter, substantially as hereinbefore described.
In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
HERBERT COTTRELL. Witnesses:
