SAND AND WATER FEEDMECHAIEHSM FOR STONE-SAWlNG MACHINES.

SPECIFICATION forming part of Letters Patent No. 352,916, dated November 23, 1886.

Application filed September 17, 1885. Serial No. 177,355. (No model.)

To all whom it may concern.-

Be it known that I, JOHN HENRY FRENIER, of Rutland; county of Rutland, and State of Vermont, have invented new and usefullmprovements in Sand and Water Feed Mechanism for Stone-Sawing Machines; and l-do hereby declare that the following is a full and exact description of the same, reference being'had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to that class of machines employed for elevating and distributing sand and water to stone-sawing'rnachines, whereby' the saws are constantly supplied with sand and water, or chilled shot and water, by means of which the stone is abraded or cut away. It is also adapted to machines for grinding and polishing stone.

The object of my invention is to provide a means for automatically supplying the sand and water mixture to the saws, said supply being taken from the drain beneath the stone, thus keeping up a constant supply of the same; and it consists in an improved pump and connection,'by means of which the sand and water mixture is constantly agitated and thereby kept in suspension during its course, as will be fully described hereinafter. I v

In the drawings, Figure 1 represents a side view of my invention as applied to an ordinary stone-sawing machine; Fig. 2, an end view of a spiral coil, which has the pipe wound in three rows, one upon the other, instead of in. one row, as shown 1n Fig. 1; Fig. 3, a section of a portion of the raising apparatus shaft;

Fig. 4, a section of the open inlet end; of the coil, with a removable mouth-piece. Fig. 5 is a partial side view'of a raising mechanism adapted for small machines, the system of gearing employed in Fig. 1 being dispensed,

with; Fig. 6, a modified form of construction, in which a stationary discharge-pipe isemployed instead of arevolving one; Fig. 7, a front view of the distributing-reservoir and the distributing-pipes leading therefrom; Fig.

8, a partial sectional View of the reservoir and.

one of its distributing-pipes with its valve;

' Fig. 9, a top view of. the pipe and valve shown in Fig. 8; Fig. 10, a modified construction of a distributing reservoir with its pipes and valves, and Fig. 11 a sectional detail View of one ofthe pipes. 1 I

To enable others skilled in the art to make and use my'invention, I will proceed to describe fully the construction and operation of the same. a I

' For convenience and clearness of description the invention will be described under several heads, as follows: First,-the main supply-tank and its connections; second, the raising mechanism, and, third, the distributing-reservoir'and its pipes. l a

First. The main supply-tank and its connections: r

- A represents a tank of any suitable size and shape, which is-located on a longitudinal plane sufficiently below the plane of the stone-sawin g machine to obtain the proper fall for drainage. a represents an overflow-opening, by means of which the mud, worn sand, and detritus resulting from the sawing action is car ried off. In this tank is placed the main supply of sand and water invsuch quantities as to fill the same up to the normal level, which is some distance below the line of the shaft of the raising mechanism, as shown. B represents a drain-conduit located below the stone, and leading away to the tank A, as shown partly broken off in Figs. 1 and 6. By means of this drain-conduit the water and sand which fall from the stone andsaws are delivered again into the main supply-tank.

b represents a screen located at the proper point on the conduit, by means of which stones and pebbles are prevented from entering the tank.-

0 represents an auxiliary tank located above the main tank A, and connected therewith by a' proper pipe or trough,c, through which fresh sand is supplied to the main tank at proper intervals in proper quantities to compensate for the waste.

0 represents a water-supply pipe having a cock, 0', by means ofwhich thesand in the auxiliary tank is properly stirred and delivered through the pipe or trough 0 into the main tank A.

' Second. The raising mechanism: D represents a shaft held by any proper bearings upon the tank or other suitable place,

upon which is located a drum, as-shown in.

Figs. 1 and 6, or spider-arms,-as shown in Fig.

employed.

and driven.

d (I represent collars of any suitable construction, by means of whichthe bearings on the shaft are protected from the sand.

E represents a section of pipe wound spirally upon the drum or spider-arms, either in single rows, as shown in Figs. land 6, or in three rows, as shown in Fig. 2, or any other desired number of rows within proper limits. This pipe, as shown in the drawings, is wound spirally, but it may be wound in any form desirable; a1so,instead of a coiled pipe the spiral passage may be made or formed in the wheel, or in any other desirable manner or construction. T

e, Fig. 3, represents a sectional view of a shaft of special construction made hollow in one of its ends, by means of which connection is made with the end'of the coil proper and the flexible pipe-section e, as shown.

This shaft may be made hollow for its entire length, except where connected to the coil. By means OfxtlliS shaft the spiral coil-tube is supported The flexible tube or pipe e is made of any suitable flexible material, and is connected to the shaft D and to pipe 6 by any suitable pipe-coupling.

6 represents a pipe'section leading from th upper end of the flexible section e to a point over the distributing-reservoir, as shown, or to a central reservoir. The upper end of this pipe-section is made with a flaring mouth to better adapt it for discharging its contents :properly into the reservoir.

. e e e represent the parts of a system of gearing by means of which the movement of the shaft D is communicated to upper pipesectio'n,e. Any suitable bearings are provided for the pipe-sections, as shown.

When the mixture is not raised very high, or when the quantity to be raised is small, or for other reasons, the system of gearing shown in Fig. 1 might be dispensed with, (see Fig.

, 5,) as the motion of the drum-shaft is easily transmitted to the revolving pipe e through the flexible pipe 6; but in large apparatus, or where the discharging-pipe c is very large or very long, I prefer to use the system of gearing, as in Fig. 1, to revolve the pipe 6, thus relieving the flexible pipe of all twistingstrain.

i The apparatus represented in Fig. 6 is substantially intended in construction and operation as the apparatus represented in Fig. 1, -the only difference in construction being that in Fig. 6 the discharge-pipe is stationary, the mixture being discharged at the bottom of said pipe through the hollow shaft 6. The

end of shaft 6 is supported and revolved in a packing-box of suitable construction to form' is-adapted for connection at its delivery end 1 with conducting-pipes, so as to force the mix- 1 ture to a number of machines or to long dis-' tances.

- might be fastened to the drum or shaft in any other way, or they mightbe entirely dispensed with. By means of the revolution of the spirally-formed wheel into the tank the sand is constantly agitated and kept in suspension.

The detritus or mud is also separated and broughtto the surface and thrown off overflow-opening d.

Third. The distributing-reservoir: F F, Figs. 1 and 7, represent the distributby the ing-reservoir, of any suitable size and shape,

which is located above one or more machines, according to the circumstances of theicase; but

in circumstances where many machines are to be fed by the same raising apparatus I prefer to raise and discharge the mixture into asuitablecentral reservoir, (not shown in these .95 ervoir, and fitted with suitable pipe or other drawingsQand set above the distributing-res conduit to conduct the mixture to each one of the distributing-reservoirs, said reservoir having an overflow-pipe leading back to the main tank to prevent flooding when any one of the machines is stopped.

f represents distributing-pipes connected to the reservoir in such manner as to turn freely in any direction. By means of this construction the bent discharging ends of the pipes are i plate joint in the distributing-pipe, by means of which the flow of material is cut off when the pipe is turned out of its normal position. f

Any proper valve, also, may be employed for I determining the flow of material through the Y pipe. An overflow-pipe, b, of any proper construction, leading from the reservoir back f, Fig. 8, represents a modified construe-1 tion of reservoir with its pipes f f, two or three or more in number, grouped together, and having one single valve for the entire series.

f is made with one or more holes, f to afford passage to the mixture when open, as shown, the flowingbeing out off, when desired by pulling out the pipe f so as to close the;

holes f proper quantity of sand and water, the shaft;

The general operation 1s substantially as fol lows: The tank having been supplied with the- Dis given revolution in the proper direction by the mechanism shown for that purpose, or by I any other proper mechanism. By the revolution of the shaftthe spiral coil E and its connections are also caused to revolve. At each revolution of theshaft, theopen end of the pipe having the mouth-piece thereon is caused to ,dip into and pass through the volume of sand and water in the tank, taking up in its passage that portion that lies in'its path." As-the coil is and air are caused to progress step by step,

through the coil, and out through the flexible pipe-connection e into the upper pipe-section, c". The air volumesare of course compressed between the sand and water volumes. By means of these air volumes thesand and water volume is broken up so the friction is largely reduced and the lifting action consequently facilitated. By the employment of the air volume also the sand and water are held ina state of agitation, so that the separation of the two does not occur. By revolving the coil in the oppositedirection all the contents may be returned to the tank, this operation being necessary when the machine is to be at rest any length of time, to prevent the sand from settling and chokingthe pipes.

Some of the advantages of the described construction are as follows: The sand and water are properly delivered to the distributing-res ervoir by means ofa slow movement which vdoes not occasion the wear of the parts. N 0 piston or valves are employed. The mouth-piece protecting the end of the pipe may be readily removed, when worn out, to permit the employment of a new one. A small amount of sand and water is required, because it'is distributed to just the parts where it'is needed.

The method of raising sand and Water by the employment of alternate volumes of sand and water and air is not claimed in this ap plication, but may be made the subject of another application. The adaptation of this principle also to the raising of liquids generally is not claimed in this application, but will be made the subject of another application.
