VALVE.

Specification of Letters Patent.

, Application filed February 15,11906. Serial No. 301,160.

Patented oct. 3o, 1906.

To all whom it may concern.-

Be it known that I, JOSEPH `JAMES WiL- BER, a citizen of the United States, and a resident of Perth Amboy, in the county of Middlesex and State of New Jersey, have inventeda new and Im roved Valve, of which the following is a fu clear, and exact de- Scri tion.

T is invention relates particularly to comio bined gate and check valves, the object being to provide a valve mechanism that ma be readil reversed depending upon the direction of the flow of liquid through the pipes, and also constructed so that it may be easily regaired.

will describe a valve embodying my invention and then point out the novel features in the a pended claims.

Reference is to be had to the accompanyi2o ing drawings, forming a part of this specification, in which similar characters of reference indicate corresponding arts in all the figures.

Figure 1 is a sectiona elevation ofa valve Athe pressure 'of liquid in the pipe-section 6 mechanism embodying my invention. Fig. 2 is a section on the line 2 2 of Fig. 1, and Fig.

3 shows the pintle for the gate-valve.

Referring to the drawings, 5 desi nates the valve-casing, communicatlng at its ower portion and at opposite sides with pipe-sections 6 7.

The valve-casing at its upper end is provided with a removable bonnet 8, through Which the threaded valve-rod 9 asses, t e interior of the bonnet of course eing provided with a thread to engage the thread of therod. On the upper end of the rod is a hand-wheel 10, and on the lower or inner end is a head 11, which removably engages in a socket member 12 on a valve-controlling It will be noted that the socket member 12 opens outward at one side, so that when removed from the valve-casing it may be removed from the valve-rod.

At opposite sides of the block 13 are guideribs 14, which engage in channels 15 in the walls of the valve-casing. The block is limited in its downward movement to properly seat the valves by lugs 16, extended upward from the bottom of the casing. Detachably arranged on one side of the block 13 is a cap 17, which serves as a closure forone of the pipe members. Ah'ereshown it is arranged to close the pipe members 7. The other pipe member or the inlet thereof into the valve-casing is controlled by a gatevalve 18, attached to an arm 19, having its upper end curved and extended into a recess 20, formed in the valve-casing. The arm is arranged to swing on a intle 21, having an enlarged screw-threade head 22 for engaging in a tapped opening in one wall of the casing, the inner end of the pintle being seated in a recess 23 in the o posite wall of the casing. It will be noted t at a recess 20 is formed at each side, so that the ate-valve may be reversed or changed to cit er one of the pipe-sections. When the gate-valve is at one side, the tapped opening at the opposite side will be closed by a screw-block 24.

The block 13 is provided with a verticallydisposed channel 25, the inner wall of which is cam-sha ed or curved, as indicated at 26, and with t 's inner wall 26 the swinging arm 19 isdesigned to engage.

In the operation upon raising the block 13 will move the gate-valve to open position. Then of course the liquidiwill pass through the valve-casing and into the pipe-section 7. Upon a downward movement of the block the cam-surface 26 by engaging the arm 19 will move the gate-valve to its closed position. 1

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A valve-casing having recesses in its o posite walls, a pintle adapted to pass tgheither one of said recesses, an arm mountedm'gwing on the pintle, a gate-valve carried by said arm, a block movable inthe casing and having 'a cam-surface for engaging said arm, and means for moving said.

block in the casing. i

2. A valve-casing having recesses in opposite walls, a pintle adapted to pass through either one of said recesses, an arm mounted lto swing on the intle, a gate-valve carried by the arm, a b ook movable in the casing and'adapted to close the gate-valve, and a cap detachably arranged on the block opposite the side of the gate-valve.

3. A valve-casing, a removable bonnet at one end thereof, a screw-rod operating yof the rod, a gate-valve mounted to swing in through said bonnet, a block having rotary and detachable connection with the inner end the easing and ada ted to be moved to closed osltion by sind block, and a cap detaehab y arranged on the block at the opposite side to that of the valve.
