I GEORGE A. DAVIDSON, OF MALDEN, ASSIGNOR TO HIMSELF AND HORACE T. OASWELL, OF TROY, NEW YORK.
IMPROVEMENT IN STONE-SAWING MACHINES.
Specification describing a new and useful Improvement in Stone-sawing Machinery, invented by GEORGE A. DAvrDsoN, of Malden, in the county of Ulster and State of New York.
Figure lis alongitudinal sectional elevation of my improved sawing apparatus taken on the line :v a: of Fig. 1, and Fig. 2 is a transverse section of Fig. l on the line y y.
deep enough to let the saws, which are not al- Ways exactly level, work entirely through the stone from end to end before striking the bottom of the grooves, and thus I save the Specification forming part of Letters Patent No. 130,845, dated August 27, 1872.
.which are so cut up in a short time as to be worthless.
In this example these bars are represented as having angle pieces at the ends extending down alongside of the ends of the platform with screws G screwing into or Aagainst the platform to hold them in place; but While I prefer this arrangement I do not limit myselfl to it, for other contrivances may be employed.
Having thus described my invention, I ela-im as new and desire to secure by Letters Patcnt- The angle pieces F and set-screws G, combined with the said grooved plates and the platform, substantially as specified.
GEORGE A. DAVIDSON. Witnesses:
B. M. FRELIGE, WM. H. ECKERT.
