M U LTIPLE GATE-VALVE.
SPECIFICATION forming part of Letters Patent No. 601,472, dated March 29, 1898.
Application filed February 28, 1895. Serial No. 540,038. (No model.)
To all whom, it may concern:
Be it known that I, JOHN KNIGKERBAGKER, a citizen of the United States, residing at Troy, county of Rensselaer, and State of New York, have invented a new and useful Multiple Gate- Valve, of which the following is a specification.
The objects of my invention are to construct a gate-valve which may be located at the j unction of several pipes to connect them and be operated in such a way as to shut off independent from the others one or more or all the passages leading through the junction and to arrange the parts so that they will be easy to assemble and be true in operation. I attain these objects by the mechanism illustrated by the accompanying drawings, in Which Figure l is a plan of the valve with the cover removed. Fig. 2 is an elevation of the cage or removable guides for the gates. Fig. 3 is a section of one of the gates, the carrierwedge, center wedge, and stop-wedge. Fig. 4 is a front view of the gate, showing by dotted lines the carrier-Wedge, the center wedge, and stop-wedge. Fig. 5 is a vertical section of the valve. Fig. 6 is a plan and elevation of gate. Fig. 7 is a section cut by the horizontal plane 7 7 when passed through the elevation of the valve at that point. Fig. lS is a section of one of the guides as cut by the plane 8 8.
Similar letters refer to similar parts throughout the several views.
The body or casing of the valve O is provided with the branches B B2 Bs B4, to which may be attached pipes at the flanges F', F2, F2, and F4. The opening of each of these branches is controlled by the separate gates or valves G G2 G3 G4, which are respectively raised or lowered by the screw-threaded stems D D2 D3 D4, which pass through correspondingly-threaded nuts in carrier-wedges E' E2 E3 E4. From the carrier-wedges E E2 E2 E4 are suspended the said gates by means of the lugs H, which lit into recesses in the said carrier-wedges.
The cage which forms the guides for the gate to and from their positions is removable from the body or casing C, although this is not absolutely essential, yet by having the guides so arranged they may be readily faced with bronze, if made of cast-iron, whereas if said guides were cast integral with the casing they would not be accessible. By having removable guides the molding of the parts is rendered more easy and the proper fitting of the pieces to their respective positions made more certain. Y
The cage or guide being in position in the case of the valve, the sides J of the cage form guides for the backs A of the carrier-wedges EE2 E3 E4, so as to guide them to and from the seats when they are raised or lowered by the screw-threaded stems,which are operated by the nuts L in the usual manner. When any one of the gates G is lowered to its seat, the stop-wedge M, whichis suspended in the carrier-wedge E, strikes the stop N in the bottom of the casing and is held stationary. The carrier-wedge descending causes the center wedge O to travel outward against `the back of the gate, thus forcing the gate to its seat.
The backward pressure or reaction of the wedging is sustained by the rear or projecting arms of the carrier-Wedge at A, resting against the guides J. From this explanation it will be seen that the guides J serve the purpose of holding the parts in their proper places and resisting the reactions of the seating pressures.
From the above description of the apparatus it will be apparent that each of the openings may be independently shut off, allowing lcirculation through the remaining arms, or
all the openings may be closed. This ability to control the iiow is very desirable, for where all four gates are operated by one stem the closing of one gate closes all, which renders it much less convenient than the one herein described.
The guide or cage is made so that its upper partU is on a level with the cover S. When the cover is fastened on by the bolts T, the cage is securely held in position. The uprights or guides of the cage are connected at their upper and lower ends by diagonal ribs A', which hold them in position andenable them to withstand the strains they are subjected to.
What I desire to claim as new and of my own invention is- IOO l.
