SPECIFICATION forming part of Letters Patent No. 377,660, dated February 7, 1888*.

'Application filed Jane, 1886. Serial No. 204,060. (No model.)

To all whom it may concern:

, Beit known that I, VALENTINE G. BARNEY, a citizen of the United States, residing at Charles City, in the county of Floyd and State of Iowa, have invented certain new-and useful Improvements in Stone-sawing Machines; and

and to letters or figures of 'reference marked plete machine.

thereon, which form a partof this specification.

Figure l of the drawings is arepresentation of an elevation, partly in section,4 of the com- Fig. 2 is an enlarged detail section of the pump and tank. Fig. 3 is a modification.

This invention relates to improvements in stone-sawing mechanism, the main objects being to feed the necessary sand and water automatically to the saws, and to automatically separate the used and worn sand from the new and sharp sand.

vThe invention consists in the construction and novel arrangement of parts hereinafter described, illustrated in the drawings,- and pointed out in the claims.

Referring byletter to the accompanying drawings, A designates the frame of the ma` chine, upon which the gang-frame A', holding the gang of saws a a, is reciprocated by a pitman, c', in the usual manner, the block of stone that is operated upon being supported on the main frame over the pit or tank a2 at the lower part of said frame.

B is a rotary pump, the wheel or piston B' of which is so geared or connected to its motor as to run Very rapidly. The wheel B is made, preferably, to fit loosely in its casing, so that the water is made to flow, principally, by the rapid motion of the wheel, as in a propeller, centrifugal or other pump that Works on this principle. The said wheel turns on a step, C, secured to lthe floor of a receivingtank, C', as shown, the step-seat c being secured within the vertical hollow shaft c' ofthe pump-wheel, preferably at a point above vthe tank C.

- D is a clear-water tank situated at a point tate therefrom, and d is a pipe discharging from said tank into the open upper end of the vertical hollow shaft c of the pump-wheel. The step-seat is perforated. centrally, so that water will descend through the shaft and said seat tolubricate the step.

dis a tube branching Vfrom 'a pipe, X, that descends from the pipe D to the sand-box X. The tube d communicates at its lower end with the lower orifice of an axial perforation of the step, so that water can descend from the tank and lubricate the step by rising centrally through it to the step-seat.

.fr is the tube or nozzle through which the sandbox discharges into the receiving-tank C.

E is the discharge-pipe of the pump, *rising therefrom, then bending horizontally, and E is the distributer, consisting of two oppositelyinclined boards situated. below the end of the discharge-pipe and secured to the frame of the machine, as-shown. The distributermay` be of any kind in common use, but preferably has f upon its outer surface riffles and gates, preferably similar to those shown in the patent granted to me on the 10th day of February, 1885, and numbered 312,068.

The discharge-tube E is divided in its'hori-A zontal portion into an upper and lower branch, e e', respectively. The unworn sand will travel at the lower part of the pipe E, and willoonsequently enter the lower branch, e', and be thrown out on the distributer E', while the wornsand will pass to the upper branch, e, and be-thrown directly out of the machine.

H is a pipe connecting the pit c2 of the machine to the receiving-tank C', or to the casing of the pump should the tank Obe omitted.

The water descends through the pipe X to the sand-box from the clear-water tank, as seen in Fig. l, and a branch, d', takes the clear water from the pipe X above the sand-box to lnbricate the step from its lower end. The np-V *per branch, e, of the tube E discharges immeroo I am awareof Patent No. 321,293, granted since my patent above referred to, in which mechanism is employed for feeding sand and water in connection With stone sawing and rubbing machines.

In the application of Valentine G. Barney and B. Lester Barney, filed November 4, 1886, Serial No. 218,001, a machine in many respects similar to that shown in present application is shown; but it has the additional features of the coil-pump, the vertical sand-cleaner, the apparatus for returning the sand into the tank that contains the coil-pump, the stuliing-box, with packing to protect the joint of piping, and the mechanism for raising and lowering the saw-frame. These points are not claimed in present application. The application of Barney and Barney has not the divided tube for separating sharp from worn sand, nor has it the step for the pump lubricated with water, and such parts have not been claimed therein. As both are stone-sawing machines in which Water and sand are fed to the saws, they both necessarily have pumps to raise the mixed sand and water, pipes to convey the same, and distiibuters to feed the mixture to the saws.

Having described this invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a stone'sawing machine, the combination of the rotatory pump, the receiving-tank surrounding the same, the discharge-pipe having its horizontal portion divided into the upper and lower branches for the used and unused sand, respectively, and means, substantially as described, to distribute the unused sand mixed with water, substantially as specified.

2. In a stone sawing machine, the combination of the rotatory pump, the surrounding receiving-tank, the discharge-pipe from the pump, with its horizontal part divided into the upper and lower branches, and the distributer-board situated below the end of the lower branch of the dischargepipe, substantially as specified.

3. The combination of the pump B, having the wheel or piston B', the receiving-tank C', the discharge-tube E, divided into the two branches e e', the distributer, the sand-box G and connectingpipes, and the pipes H, connecting the pit of the machine with the receiving-tank, substantially as specified.

4. In a stone-sawing machine, the combination of the rotary pump, consisting ofthe easing B and piston B', the perforated step C, the tube c', having within a bearing for the upper rounded end `of the step C, the clear-water tank D, and the pipes X and d', whereby water is conveyed from said tank to the step C, substantially as specified.

In testimony whereof I aiix my signature in presence of two witnesses.

VALENTINE G. BARNEY.
