UNITED sTATEs PATENT oEEicE.
JOSE TOLL, OF LOOUST GROVE, OHIO.
MARBLE-SAWING MACHINE.
Specication forming part of Letters Patent No. 15,713, dated. September 9, 1856; Ressued December 9, '1856, No. 413.
To all whom it may concern Be it known that I, J osE TOLL, of Locust Grove, Adams County, Ohio, have invented a new `and useful Improvement in Marble- Sawing Machinery; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being hadto the annexed drawings, making part of' this specification.
My improvements have relation to an arrangement of duplicated and connected fender bars and guiding pieces, by which the bar of one set of saws at either end of the set, serves as the point or fulcrum for the adjustment of the corresponding pieces of the other set at that end, a single movement result-ing in a uniform adjustment of the guide pieces of an entire set; and enabling two interposed sets of diverging saws, to be driven from a single crank or its equivalent.
In the annexed drawing, Figure l is a side view of a machine embodying my im` provements. Fig. 2 is a top view thereof, Fig. 3 is a side View of a fender bar.
(a) is a heavy framing of sill pieces, sup-4 porting four stanchions (b). To the inner sides of the stanchions there are aiixed cross rails (c) which in the present illustration are four in number, two above and two below. These rails (c) have vertical slots (cl), holding or containing bolts (e) for the attachment of guide strips (f) eight in number; a pair of these strips is attached as represented at the desired angles at or near each end of each cross rail (o), one of each pair of strips being fastened above the rail and the other below it.
Saw blades (g g') (G G) are attached to posts (h I-I) in the manner represented namely-with a blade (g) fixed at the right hand side of one post and at the left hand side of the opposite post of the gate above;
another blade (g) being similarly fastened to the same posts below. A stretcher (i) is then keyed fast between the posts of each pair midway between the upper and lower blades. Several sawgates (g g 7L z') (g g it d) being thus constructed, others "(Gr G I-I I) (G Gr H I) are similarly formed with the difference that the blades (G G) of the second set are in each instance fastend on their posts reversely to those before described, so as to bring blade opposite to blade and post to post alternately.` Then the two several kinds of gates being placed alternatingly side by side, are secured to their respective sets of fender bars (j j) (J J) by means of cleats (o) (O) lwhich having been carefully adjusted are bolted to the `slotted bars j j J J This Inode of attachment, while it compels the gates to travel to and fro with the bars, permits them to sink their way through the stone. The upper and lower bars (j j) to which the first set are secured being placed a little in advance of and on a level with the corresponding bars (J J of the second set respectively, each pair of adjacent bars of the respective sets are then connected by a pair of links (lcfs), holding them constantly parallel with varying longitudinal adjustments of the bars as hereafter explained.
Each respective upper and lower pair of bars of each set of `saws have their corresponding ends connected by rails (Z Z) (L L). The connection of the rails and bars being in each case made by means of a single round bolt (m) forming a hinge joint so that the two bars and the connecting rails of each set constitute a quadrilateral framework, capable of assuming any angularity that may be desired. These sliding rails bear against the guiding strips (f f F F) which, being bolted at any desired corresponding parts of the rails (o) determine and govern the direction of mo'V tion of the gates; the sliding rails (Z Z L L) by their hinged connection to the bars (j j J J assuming the corresponding angularity to the strips, and the saws also having been previously carefully adjusted to parallelism with their sliding rails and secured thereto by the bolts and cleats upon the slotted fender bars, conform simultaneously and automatically to any adjustment of the guide strips; so that one guide strip of each set being fixed as desired, the sliding rails belonging to the other strips afford an accurate gage for the adjustment of their respective strips. The guide strips of one set being fixed, the corresponding fender bars afford by the linked connection (7: c) a convenient and fixed. fulcrum or bearing for the relative adjustment of the other set. This linked arrangement also enables a single crank to work all the saws of both sets, the crank being connected to a post (IVI) attached to the two forward fender bars of the firstset.
In operation, both sets of gates being simultaneously drawn forward by the crank each set is compelled by its respective guide vstrips to move in a. path parallel with its (g) are posts supporting the upper platform.
I am aware that there have been heretofore machines for sawing marble in taper form and therefore make no claim to such; but
What I claim as new and of my invention is- The particular combination and arrangement of the fender bars J, J', j, j', with the adjustable guide pieces, when the same are constructed and arranged to operate in relation to each other in the manner and for the purpose set forth.
In testimony whereof, I hereunto set my' hand before two subscribing witnesses.
JOSE TOLL.
