SAND AND WATER DISTRIBUTER FOR STONESAWING MACHINES.

SPECIFICATION forming part of Letters Patent No. 384,615, dated June 19, 1888.

Application filed June 23, 1887. Serial No. 242,234. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN H. FRENIER, of Rutland, in the county of Rutland and State of Vermont, have invented a new and useful Improvement in Sand and \VaterDistributers for StoneSawing Machines, of which the following is a specification.

In stone-sawing machines, which comprise sawing-blades of metal for marble and other stone, it is common to employ sand asa means of cutting the stone by the operation of such blades, and water to distribute the sand; and my invention relates to a novel construction of sand and water distributer, whereby the sand will be more evenly distributed to the several blades in the sash or frame during the reciprocating movements of such sash or frame, and the saws or blades supported therein.

The invention consists in the combination, with a reciprocating saw sash or frame and a gang of saws therein, of a sand and waterdistributer pivoted above and parallel with the line of movement of the saws, and a rod or connection for-imparting to the distributer an oscillating or swinging movement transverse to the line of movement of the saws.

The invention also consists in other combinations of parts, particularly hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical sectional elevation of a saw sash or frame and saws, a stone, a fixed frame, and a sand and water distributer embodying my invention. Fig. 2 is asectional view of the sand and water distributeralone, upon a larger scale, and upon a plane at right angles to Fig. 1. Fig. 3 is asectional view upon the plane of the dotted line x m, Fig. 2. Fig. 4 is a sectional view of a horizontal pipe with numerous outlets anda whereinitis arranged,theoutlets being 'rran'ged to deliver upward against the top of the trough, and the said pipe and trough forming part of the oscillating or swinging distributer; and Fig. 5 is atransverse section on the plane ofthe dotted line yy, Fig. 4.

All the figures except Fig. 1 are made upon a larger scale than said Fig. 1, and in all of the figures similar letters of reference designate corresponding parts.

Referring first to Figs. 1, 2, and 3, A designates a fixed frame, which may be of timber,

and which is provided with suitable guides for I a reciprocating saw sash or frame, 13, wherein are secured a number or gang of saws or blades, 0.

It will be. understood that the term saw as applied herein designates simply astraightedged blade, which serves to cut the stone through the intervention of sand or analogous globules or particles of material carried to the cutting-point by water. The saws O are secured in any ordinary way in the frame or sash B, and the saws and sash are reciprocated with ordinary rapidity.

Above the stone D is arranged a sand and water distributer,which, as here represented, consists of a receiver, E, a pipe, F, leading therefrom, and a cross or horizontal pipe, F, which is provided with numerous outlets throughout its length, as hereinafter described. The receiver E is pivoted upon a rock-shaft, e, and, by means of a rod, 6, attached to an arm, 6 projecting from said rockshaft, the sand and water distributer is oscillated in the directions indicated by the doubleheaded arrows in Fig. 1. By this arrangement of parts the sand and water, which are delivered to the receiver E through a pipe, f, are distributed across the stone, and transversely to the several saw-cuts, s, formed'by the saws or blades 0, and consequently a very uniform distribution of the cutting material to the several saws or blades C is provided for.

Although sand is the only material herein described, it will be understood that small shot and other analogous particles are frequently used in lieu of sand, and constitute a full equivalent thereof, the purpose of such particles being simply to afford an abrading material, which by the reciprocating movement of the saw-blades G is pressed against and caused to cut the stone.

The particular construction of the sand-distributer will be understood from Figs. 2 and 3. I have represented the receiver E as provided at the top with a sieve or strainer, 6, whereby small stones delivered through the pipe f are prevented from entering the receiver E and the pipes connected therewith.

The receiver is secured, as aforesaid, upon a too roek'shaft, c, and, as here represented, c are suitable hearings in which the rock-shaft may oscillate, and said rock-shaft has an arm, 6', at one end, with which the operating-rod e is connected.

I prefer that the pipe F, leading downward from the receiver E, shall have telescopic communication with a second section of pipe applied thereto, and I have here represented the pipe F as sliding within a section, F, which may be secured to it in any position by a set screw, 1'. Consequently the length of the distributor may be increased or, diminished as may be desired for operating with stones of different height.

The horizontal pipe with which the downwardlyextending pipe F F communicates may be either truly or approximately horizontal, it being not necessary that it be in a truly horizontal plane, but it being here described as horizontal to distinguish it from the downwardly-extending pipe F F. I have here represented the pipe F as composed of short sections of pipe and T and elbow fittings, in a well-known manner, and the pipe F has at intervals in its length outlets f which deliver the sand and water from it. In Figs. 2 and 3 these outlets are represented as presented downward, and the pipe F is shown as arranged within a trough, G, the side portions of which may be adjustable toward and from each other, so as to maintain a narrow slot, slit, or outlet, h, in its bottom. I have here shown the trough G as sustained from the pipe F by bearers or clamps f, secured upon the trough, and which holds upon the pipe, and I have here represented the abutments II as arranged opposite each outlet f,and against which the sand and water will be directed. The sand and water which escape from the outlets f 2 being directed forcibly upon the abutments II, the latter will serve to spread and throw off the sand and water in directions lengthwise of the trough G, and consequently from the narrow slot or slit h will issue an approximately continuous sheet of water; or, in other words, the sand and water will be delivered from the whole length of the slot h. The abutments H may have projections riveted in one of the sides of the trough G, and at the opposite ends are projections or tongues which project through the opposite wall of said trough, and through which are inserted keys f By means of these keys the side portions of the trough may be adjusted somewhat toward and from each other, and provision for varying the width of the sloth may thereby be afforded.

Instead of the outlets f 2 from the horizontal pipe F being presented downward, as shown in Fig. 2, they may be presented upward, as shown in Figs. 4 and5; but the sand and water will by impact against the top of the trough be sprayed or scattered, and will be delivered throughout approximately the whole length of the narrow slot or slit 7:. at the bottom thereof.

In Figs. 4 and 5 I have represented rods j, which extend across the trough,G and are pro vided with keys f, whereby the sides of said trough maybe adjusted toward and from each other.

It will be seen that by my invention I provide a very simple system of devices, which serve, by their movement transverse to the line of reciprocation of the saws G and the sash or frame 13, to deliver water and sand or other abradi ng material uniformly to the several sawcnts s, and in the parts of my apparatus no opportunity is afforded for the ready separa tion of sand from the water and the deposit of the sand or other cutting material.

It will be understood that the receiver or reservoir E may be supplied with sand and water from any suitable pump; but for this purpose I prefer to use such a pump as forms the subject-matter of my application for patent, Serial No. 189,913, filed January 27, 1886.

Although I at present deem it preferable to so arrange the receiver and distributer that it may be swung or oscillated in a direction transverse to the line of reciprocation of the saws, I may in some cases arrange the receiver and distributor so that they will be swung or oscillated in a direction parallel with the line of movement of the saws, as by this latter arrangement the advantages of my invention may, in a measure at least, be secured.

I am aware that apparatus of various kinds have been contrived for distributing water and sand upon a stone during the sawing operation, and hence do not claim any and all apparatus for this purpose. In this connection I am aware of the Letters Patent, No. 123,217, granted January 30, 1872, to V. G. Barney; No. 336,840, granted February 23, 1886, to F. H. Cook, and No. 352,916, granted November 23, 1886, to J. H. Frenier.
