ARTHUR w. masons, or BROOKLYN, NEW YORK.

COCK.

SPECIFICATION forming part of Letters Patent No. 275,406, dated April 10, 1883.

Application filed November 23, 1882. (No model.)

To all whom it may concern Be it known that I, ARTHUR. WEBB PAR soNs, ofthe city of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in V (Jocks, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, in which like letters indicate like parts. Y

My improved cock is peculiarly adapted to be used in connection with filtering apparatus, although it may be used with any other apparatus or system of piping, if desired.

The peculiar feature of the cock consists in so constructing its barrel and plug that the plug shall have but two passages through it, which shallconnect with suitably-located ports through the barrel to which the piping shall be connected, whereby what may be called direct, reverse, and by-passing flows of liquid may be obtained; and the best method known to me of constructing it is to have the centers of the two passages in the plug and the centers of all the ports in the barrel on the same transverse plane.

I do not claim, broadly, a single cock so constructed that by rotating its plug liquid may be made to flow through such apparatus as may be connected with it in opposite directions, and also by-passed, cutting out such apparatus, for I am aware that such a cock has been constructed.

In the drawings I have shown the cock constructed with the ports and plug-passages all on the same plane, and have represented it as connected with an ordinary filtering apparatus. The ports in thebarrel of the cock, however, need not necessarily be on the same transverse plane. They may be in different planes, the passage or passages through the plug curving to connect with them.

Figure] illustrates a section of the cock through the center of the passages in the plug and of the ports in the barrel and connected with a filter not in section. The cock-plug is in the proper position to filter the water. Fi 2 illustrates the cock in the same section and with the plug in position to efl'ect a reverse flow of liquid to cleanse the filter. Fig. 3 illustrates the cock in the same section and with the plug in position to bypass the liquid.

Fig. at illustrates a top view of the cock, showinglthe handle and stops to regulate the turning of the plug.

In the drawings, X is the filter. X and X are two ordinary screw-conplin gs, whereby the filter may be readily disconnected from the piping and removed.

A is the barrel of the cock, furnished with live ports, H, S, D, F, and F. They'are distaut from each other from center to center on the inside of the barrel exactly one-fifth the circumference of the barrel on the inside. The port H connects with the house-pipe, S connects with the supply-pipe,1) connects with the drain-pipe, F connects with one end of the filter, and F"'with the other end.

0 is the plug ofthe cock. 0 and (l are the two passages through it. These passages are so distanced that C connects with any two of the ports which are adjacent to each other, and O connects with any two ports which are separated by one interposed port; and to secure this the centers of the ports on the inside of the barrel should be, as already stated, substantially onefifth the circumference of the cock on the inside of the barrel apart. 0 extends to the periphery ofthe plug, although it is not necessary that it should do so. 0 passes through the plug, leaving the bearingsurf'ace 0 outside of it. By reference to the drawings it will be at once seen that when the plug is turned into the several positions illus trated the liquid brought to the cock by the supply-pipe S will be made to flow in different directions, as I have. indicated by arrows on the drawings-that is to say, in Fig. 1 the water is passing from the supply-pipe through the plug-passage O to the filter, through it and the plug-passage O to the house-pipe. When desired to cleanse the filter, the plug is turned to the position shown in Fig. 2. Now, the water passes from the supply-pipe through through the filter in the opposite direction, and thence through 0 to the drain-pipe, cleansing the filter; and when the plug is turned as strike, thus determining the degree ofrotation I having five ports in its barrel and two pasto be given to the plug. sages only through its plug, one passage con- Having thus described my invention, 1 neeting with adjacent ports and the other pasclaimsage conuectin g with alternate ports, substan- 5 1.
