UNITED STATES EMANUEL FOERSTER,
PATENT OFFICE.
OF NEW YORK, N. Y.
PROCESS OF CUTTING STONE.
SPECIFICATION forming part of Letters, Patent No. 419,194, dated January 14, 1890.
Application filed January 5, 1889. Serial No. 295,502. (No model.)
.To all whom it may concern.-
Beit known that I, EMANUEL FoERs'rER, of the city of New York, in the county and State of New York, have invented an Improved Process of Cutting Stone, of which the following is a specification, reference being had to the accompanying drawings,*form ing part of this specification, in which--` Figure 1 is a vertical longitudinal sectional elevation of a stone-cutting machine by which my process can be carried out` and Fig. 2 is a cross-sectional view of the reciprocating tools which I use in my process.
In carrying out my invention I feed the stone to be cut from behind the cutting-tool or in the direction in which the cuttingtool moves to cut the stone.
In the accompanying drawings I have shown means for carrying out my process.
In said drawings, the letter A represents the frame of a stone-cutting machine, at the upper part of which is suitably journaled a horizontal sha-ft B, that is provided with an eccentric a. The shaft B may be rotated in any suitable manner.
Dis a sl-iding reciprocating toolcarrying plate that is guided in movable guides b, carried by the frame A. The reciprocatingplate D is pivotally connected by straps (l with the eccentric a, whereby when said eccentric rotates the plate D will be reciprocated.
c is an arm conected with the strap d, which arm is also pivotally connected by a link f with a sliding rod g, whereby when the rod g is moved the reciprocating` plate D will be swung or raised and lowered.
E is a frame or track upon whicha stonecarriage F is adapted to move.
The frame E is adapted to be raised and lowered and is supported by screwerods 7L at the sides of the machine, which are turned by suitable means, so as to raise and lower the track or frame E and thereby the stonecarriage F.
i is a longitudinal shaft that extends parallel with the track or frame E, and is connected by gearingj Z m with the stone-carriage, so that as said shaft is rotated the stonecarriage will be moved longitudinally. The shaft t' is connected by gearing n, o, p, and q with the main shaft B of the machine, whereby the shaft is driven.
The above construction and arrangements of parts are similar to those shown in Letters Patent of the United States No. 392,601,
granted toYY me November 13, 1888, and I therefore refer to such patent for a more particular and detailed description of the construction and operation of the before-mentioned stone-cutting machine; but it is evident that the reciprocating plate D may be actuated and the stone-carriage F raised and lowered and moved longitudinally by means other than that shown herein, if desired.
GrV represents the cutting-tool, which is carriedr by the reciprocating plate D in suitable manner.
In cut-ting the stone by my process, and also in order that the tool will not chip or break off the stone, as is done with stones that are fed toward the tool, I move the stone from under the tool, or, in other words, I move the stone in the direction in which the cutting-tool is moved to cut. For inst-ance, suppose the cutting-tool G to be moved in the direction of the arrow in Fig. 1. To dress the stone, the stone is moved in substantially the same direction as indicated iu said iigure by the arrow a4. Then setting the stone to be cut, the stone is first placed under and behind the tool, and is thenmoved toward the tool in the direction of the arrow a or of the cutting movement of the tool, so that the edge of the stone will first be encountered by the tool. As the tool 'is reciprocated and the stone is moved in the direction of the arrow a4 the tool will cut or dress the stone that is fed to itvfrom beneath or behind, thereby leaving a dressed edge on the stone in front of the tool, as shown. As the tool does not encounter a mass of stone in its front, but rather shavcs the stone oit from behind, the stone will not be chipped or brokeu, but an even cutting' will be effected. There being no part of the stone to be cut in front of the tool, there will be no chipping of the stone.
Having now described my invention, what I claim isr1`he process of dressing or cutting stone herein described, which consist-s in feeding the stone to the reciprocating toolV in the direction of the cutting stroke of the said reciprocating cutting-tool, substantially as speciiied.
EMANUEL FOERSTER.
