' STONE-SAWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 373,300. dated November 15, 1887. Application filed April 14, 1886. Renewed October-7, 1887. Serial No. 251.770. (No model.)

To all whom it may concern.-

'Be it known that We, AARON E. NORTH and WILLIAM K. SHELDON, citizensof the United States, and residents of West Rutland, in the county of Rntland and State of Vermont, have invented certain new and useful Improvements in Stone-Sawing Machines, of which the following is a specification.

Our invention relates to improvements in stone-sawing machines, and has for its object the provision in a machine of the class named of means for insuring an even distribution of the feed-water and sand over a large surface, for delivering the said feed-water and sand to r 5 any desired point of said surface, and for ad- I rangement, and combination of the several parts for service, substantially as hereinafter described, and specifically pointed out in the claims.

In the drawings, Figure 1 represents aplan View of a stone-sawing machine embodying Fig. 2 is a side elevation our improvements. thereof. Fig. 3isa longitudinal sectional View taken on the line a: a; of Fig. 1. Fig. 4 is a transverse sectional view taken on the line yy of Fig. 1. Fig. 5 isahorizontal sectional view taken on the line 2 z of Fig. 2. Fig. 6 is a detail view of the distributing-box-raising mechanism detached from the machine. Fig. 7 represents a detached detail view of one of 5 the water and sand distributing nozzles.

Referring to the drawings, in which similar letters of reference denote similar parts, A designates a stonesawing machine having cornet-posts A, connected at their bottoms by 4.0 longitudinal and transverse timbers A) A provided with a platform, A, to receive the stone to be operated upon, and at their tops by similar longitudinal and transverse tim-v bers, A A, the former, A of which is provided with short upwardly-projecting studs a,

that form supports for rails A, the purpose of which will be hereinafter explained.

' O designates the saw-holding frame, having side rails, 0, end rails, c, and adjustable saws c, operated in the usual manner.

D designates the distributing-box, consisting in sides d, having upwardly-projecting portions (1 and ends d d the latter of which connect the inclined ends of the projections d.

E E designate water-cards, placed within and supported in an inclined position upon blocks e e, secured to the sides of the box D. These cards E E consist of longitudinal side rails 6, connected together by transverse rails 6 that support a series of thin laths. e e designate studs that project downwardly from the inner ends of the side rails e of the water-cards and operate, in connection with the block's e, to limit the outward movement of said cards.

F designates a water-table,that is secured to and extends from side to side of the box D, Within and near the top thereof. (See Fig. 3.)

' This table consists of a central horizontal portion, d, and downwardly-inclined side portions, at, placed a short distance therefrom.

G designates the feed-pipe, that extends from a suitable reservoir, P, above the machine to a point above and intermediate of the ends of the table F, to conduct water and sand from said reservoir to the stone under treatment.

We preferably make the pipe G in two sections, 99, one of which, the upper, g, is smaller in diameter than the other, 9, and is placed and moves within the upper end thereof, whereby said pipe may be adjusted in length and held at any desired point by an adj usting-- screw, 0. The lower end of the pipe G is connected by a T-coupling, gflwith laterally-projecting pipes G, providedat predetermined spreaders-H, formed of short fiat sections of metal plate, having notches it formed in their side edges at points intermediate of their ends to engage the bars 9, formed by the uncut portions of the pipes, for the purpose of holding the spreaders in position, and at right angles to the longitudinal axis of the pipes or nozzles G for the purpose of spreading the feed-water and sand over a large surface and in different desired directions, for which latter purpose the nozzles G2 may be wholly or partially rotated.

G designates plugs that close openings formed in the Tcouplings g g, opposite the nozzles G for the purpose of removing obstructions from said nozzles.

To accommodate stone of different thicknesses, we provide that the distributing-box D be adjustable in vertical and longitudinal (lirections, which results we accomplish by and in the following-described means and manner, viz:

I designates timbers,that are seen red at their lower ends to the opposite sides of the box D, and project thence upwardly,and are connected together at their tops above the machine by a rail, I.

I designates rackbars secured to the forward surfaces of the timbers I, the teeth of which engage the teeth of pinions K, that are mounted upon a shaft, K, near the ends thereof, journaled in movable boxes K placed outside ofsaid pinions and supported in manner hereinafter described. The piuions K are each provided upon one side with ratchetwvheels K, preferably of greater diameter than said pinions and rigidly secured thereto, and upon their opposite sides with bosses 7;, having circumferential grooves 7t, to receive the curved ends of U -shaped straps L, that extend at each side of each of the rack-timbers I, and are connected together upon the back of said timbers by bolts Z, provided with friction-rollers l, as shown.

M designates pawls pivoted upon one side, preferably the outer, of each of the timbers I, to the straps L, and provided with oppositelycurved free ends m, that engage the ratchetwheels K, and, as before stated, hold the bars or timbers I and box D at different desired elevations.

The journal-boxes K are each provided with downwardly-proj eeting side flanges, it, that extend at each side of the rails A hereinbefore described, and said boxes may or may not be provided at each end with rollers 7?, that move upon the upper surfaces of the rails A. The boxes may be operated back and forth upon said rails in any desired manner.

The operation of our invention will be understood without further description, it being understood that the distributing-box D may be raised or lowered or movedback and forth to accommodate different-sized blocks of stone, and that the pipe G will, by reason of its adjustable features, accommodate itself to such movements of the box; also, that the nozzles G may be turned in their couplings.

If desired, a circular spreader may be used in lieu of the ilatspreadershown atH, or such spreader may have other desired configuration of outline.

If desired, the water-cards E E and table F may be adjustable up and down in the box D.

W'ithout limiting ourselves to the exact con struction of parts shown herein,we elaim 1. In a stonesawing machine, a feed-reservoir, a feed-distributing box, a feed-distributing pipe connecting said reservoir and box, and tubular feed-nozzles having on t-away sides,
