STONE-SAWING MACHINE.

SPECIFICATION-forming part of Letters Patent No. 377,595, dated February '7, 1888.

Application filed November 4, 1886.

To all whom it may concern:

Be itknown that we,VALE1vtrINE G. BARNEY and R. LESTER BARNEY, citizens of the United States, and residents, respectively, of Charles 5 City, Iowa, and of Swanton, State of Vermont, have invented certain new and useful Improvements in Stone-Sawing Machines; and we do declare the following to be a full, clear, and exact description of the invention, such as will IO enable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of thisspeoification.

chines; and it consists in the construction and novel combination of parts, as hereinafter described, and pointed out in the claims.

Referring by letter to the accompanying drawings, A designates a drum, around which a coil of pipe is wound, p p 10 pp designating the coils, one-half of the first coil, 10, commend ing at its mouth, being enlarged.

' 'g designates an extension of the end coil, 10,

pipe n. The drum and coiled pipe form the pump. This pump is a rotary pump and has its shaft journaled in bearings on the tank Q, which receives the mixture to be raised and deposited on the stone to be sawed. L

It should be stated here that the tank Q should be always immersed in the mixture.

A is a blade which is set on the outside of the pump at an angle to scrape'the sand or 0 other material used in sawing which may settle under the wheel to or near the mouth of the pump.

13 designates a stuffing-box, on the inside of which is a circular groove, m, which is sup-' 5 plied with clear water under pressure from the pipe H, the pressure of the water in said groove in the pipe H to be greater than the pressure of the material being raised, so that the abrading material can never reach the Serial No. 218,001. (No model.)

nota positive necessity, however, as the water under pressure will be effective in preventing the material from reaching the pack-V ing without the use of the groove. It is better to use it, and we prefer to use it, and sometimes do so. The current of clear water,passing inwardly around and between the dischargepipe at and the stuffing-box B, renders it impossible for the grit to reach the packing.

B designates the pipe leading from the 7 pump to the sand-cleaner. When the sandcleaner is not used, the pipe B would'continue' to the distributer E. When used, it is a re-- ceiver into which the mixture is forced for the purpose of cleansing the sand. The sand being forced in an upward direction, the wornparticles rise and pass off or out through the pipe 0, the pipe G supplying astream of clear water to assist in cleaning the mixture. When the cleaner is not used, the mixture goes directly to the distributer..

H is apipe leading from the cleaner O tothe distributer E, two sections of said pipe being connected at D by flexible hose. The pipe H is supported'near its elbow by a cord, f, running over a pulley and connected at its lower end tov the frameof the sawingzmachine.

D is a loose-fitting pipe which is secured to the lower endfor the purpose'of raising or lowering the distributor E of'the' pipe H by set-screws d, so as'to raise and lower .it'0n the pipe H ,said pipe 1) leading to the distributer E. The distributerE consistsof a hollowstem,

X, provided with two downwardly inclined hollow wings. The distributer is provided 8 5 with a wedgeshaped divider, Z, which may be turned to conduct the material to either wing or to both wings V W, as may be desirable or necessary. The form of the distributer, I however, is not essential, and any other form '9c may be used, if preferred.

M designates the saw-frame, which is moved back and forth by power over the stone to be sawed. I

' N'is the slanting bottom which receives and conveys the mixture after passing the saws back into the tank Q, causing said mixture to pass through the wiresoreen O and the spout P.

S is a box which receives the worn material which overflows from the receiver 0 through BARNEY,

the pipe 0, and this box S is provided with a partition, 8. On one side of this partition the box S is connected by a vertical pipe, V, leading to the tank Q. On the other side of the partition the box is connected with a spout, U, which carries off the worn sand or other material away from the machine.

X is a float in the tank Q,which rests on the water therein. A cord, 1, is attached to the float X, said cord 1 passing over apulley, 2, and is connected with a flexible pipe, T, having a discharge-pipe, t. A weight,W, is connected to the opposite side of the pipe or hose T by a cord, 3, passing over a pulley, 4.

K is a sand-feed box having a descending slanting or inclined bottom. The sand-feed box communicates through a spout, L, with the spout P, leading to the tank Q.

Z Z are cross-bars, which are suspended by chains, screws, or otherwise, and held in position by slides 12 b b b, which slides move up and down on rods a a a a.

The saw-frame MI is suspended by rods q q q q, connected to said cross-bars Z Z. Said sawframe is prevented from swinging laterally by the crossed braces Y Y, and can move longitudinally only. The rods (1 are suspended on the bars Z by the loops 0, and have at their lower ends the loops c, in which rest the bearing-pieces c of the saw-frame M. But one sawframe is represented in the illustration, as that is sufficient to show our invention; but we can and do use a number of gangs,which will be usually done, and they will all be supplied with abrading material by one pump, the pipes leading to the different gangs, the latter being connected to the receiver 0. When the supply of material is greater than necessary, the float X will rise and the cords and weight W will carry the discharge-pipe t to the outer side of the partition s,so that it will pass out of the machine. VVhen the material is scant, the float falling will draw the pipe t to the inner side of said partition and the material will pass down the pipe V to the tank Q.

The operation of the machine is as follows: Tank Q being supplied with the sawing or abrading material,the machine is set in motion. The pump at each revolution takes in sand and water, or other abrading material used for sawing,and air, the proportion being about three parts air to two parts of the mixture used for sawing. As the revolutions continue and the mixture ascends the dischargepipe, the pressure from the column of the mixture in the discharge-pipe forces that in the coils to riseto one side. Allthese columns of the mixture in the coils combined, and being separated by the air-columns, which are compressed considerably, force the mixture to a height in proportion to the number of coils. The mixture passes into the receiver 0 and is there cleansed, as described heretofore, the cleansed material passing through pipe H to the distributer, where it is distributed to the saws, whence it falls onto the slanting bottom N and passes through screen 0 and spout P back to tank Q. The waste and worn particles that pass ofl' through 0 are replaced by fresh sand and water from the feed-box K, the material being washed down by a jet-pipe, J, from the elevated water-tank F through spout L and through screen 0 and spout P. The mixture in passing through screen 0 is separated from gravel and other objectionable material which it is desired to take out. The tank F supplies the water to the jet-pipe J.

A is a shaft journaled in bearings secured to the main frame operated bya crank-handle, A and provided with a ratchet-wheel, A, which is controlled by the pawl A, attached to the main frame.

A A are ropes or cords secured to the bars Z, passing over the pulley A and winding on the shaft A, those on opposite sides thereof winding in opposite directions. By this means the saw-frame can be raised or lowered at will.

WVhen the cleaner is not used, the abrading mixture goes directly to the distributer.

The material may go the round many times before being used up and worn out. The distributer is adjustable as to height for high or low blocks by means of cord f.

The pump herein described can be used for raising sand or other abrading material for the purpose of scouring or finishing marble on a rubbing bed or wheel, such as is commonly used in mills for such purposes, or it may be used for any other machine where sand must be raised for finishing marble.

F is a cord having a hand-hold at its lower end for the purpose of turning the valve -f and regulating the flow of material to the distributer.

We are aware that a pump working on a principle somewhat similar to ours, although of different construction, is now in use. Our construction, however, is an improvement on the other, that being made by a hollow passage which leads from the outside to the center, the pipe being coiled around and around upon itself. Our construction is better than that for the reason that it is more easily made, the coils being on larger curves and aligned horizontally upon the supporting-drum A. In the old construction the wheel has to be made too large in order to get coils enough to raise the material to the height that may be desirable, while ours can be extended to any length without increasing the diameter of the wheel. and the abrading material will be raised to a height proportional to the length of the coils.

The method is preferable to all others for the reason that there are no valves to wear or clog. The mixture is discharged in a continuous stream without friction or wear, except at the stuffing-box, and that we protect as described. It has also the advantage of running at a slow speed, only about twenty revolutions per minute being required.

In the application of Valentine G. Barney, filed June 3, 1887, Serial No. 204,060, a machine in many respects similar to that shown IIS V in present application is shown; but it has the additional features of the step lubricated by water and the dividedpipe to Separate the worn from the sharp sand. Neither of these is claimed in present application. In Valentine G. Barneys' application the vertical sand-cleaner, the stuffing-box with packing to protect the piping-joint, the coil-pump, and the mechanism to raise and lower the sawframe are not shown. Both beingrstonesawing machines in which sand and water are fed to the saws, they must necessarily have some points in common; but the points of difference have been carefully noted and stated.

Having described this invention, what we claim, and desire to secure byLetters Patent, 1s
