VALVE.

SPECIFICATION forming part of Letters Patent No. 556,312, dated March 10, 1896.

Application filed June 27,1895. Serial No. 554,238. (No model.) I

T at whom it may concern.-

Be it known that I, CHRISTOPHER GULL- MANN, a citizen of the United States, residing at New York, in the co unty and State of New York, have invented new and useful Improvements in Valves, of which the followin is a specification.

This invention relates to a valve or faucet which during the opening movement is loosened or lifted from its seat and during the closing movement is pressed to the seat so as to effect firm closure; and the invention resides in the novel features of construction set forth in the following specification and claims and illustrated in the accompanying drawings, in which Figure 1 is a sectional elevation of the valve open and showing a manner of use. Fig. 2 is a sectional elevation of the valve closed. Fig. 3 is a section along line a; m, Fig. 2. Fig. 4 is aview of apressure-chamber sectioned along line y y, Fig. 3. Fig. 5 is a sec tion along line .2 2, Fig. 3. Fig. 6 shows a modification.

In the drawings the valve is shown applied to use in connection with a pump-chamber 1, also known as a pulsator and familiar in such works as dredging; but of course the use of the valve need not be limited to such apparatus. The inlet 2 causes matter to be discharged into chamber 1 when a vacuum has been formed in the latter, and the outlet takes off the matter discharged by pressure in the chamber 1, as known.

The inlet 2 is shown with a valve-chamber athaving a valve-actuating shaft 5 from which extend arms 6 carrying the valve-lid part or section 7, to which is connected the lid part or section 8 by pin-and-slot connection 9 and 10 to allow the two lid parts 8 and 9 certain play or motion with respect to one another.

The lid part 8 has a nose or incline 11 extending into a hole or recess 12 in lid part 7. The closing movement of shaft 5 carrying the valve-lid 7 and 8 toward the stop 13 and the lid portion 8 being arrested by said stop while the lid portion 7 continues somewhat farther in the closing movement, the action or press ure of lid portion 7 riding along the wedge or incline 11 will press the lid portion 8 firmly to the seat to effect tight closure. A return or opening movement of shaft 5 and lid por- 17 the blades 14 are moved to give a closing swing or turn to shaft 5, while an exhaust through ports 16 and pressure through ports 17 will cause the valve to be opened. The pressure-chamber is suitably divided into compartments by partitions 18. The pressure entry and exhaust through ports 16 and 17, as known, is effected by suitable valves 19 worked by hand or by suitable well-kn0wn mechanism.

To prevent slamming of the blades 14: a dash-chamber 20 is provided. The portion of shaft 5 which projects into the dash-chamber is provided with blades 21, Fig. 5, and as the shaft rocks the blades 21 are arrested by striking soft pads or springs 22 suitably secured in the dash-chamber. Other forms of dash-chamber or dashpot might answer, as by filling chamber 20 with fluid, but the construction shown is simple.

The outlet 3 may have a like valve as inlet 2, but a simple lid-valve or other valve may be made to answer for outlet In place of operating shaft 5 by pressurewings 14., any other actuatoras, for example, a handle or lever 14may be taken as an equivalent for actuating said shaft.

The vacuum and pressure in pump-chamber 1 can be produced, as well known, by allowing steam to enter the chamber and then condensing the steam by a suitable dash or jet of water, thus causing a vacuum, while pressure in chamber 1 is readily created by allowing water or steam pressure to enter the chamber 1 as required. For controlling the water and steam inlets into chamber 1, valves as just described, actuated by a handle, as

lid and an actuating-shaft for the lid, eo1nbined with a pressure-chan1ber, actuatingwings in said pressure-chamber secured to said shaft, a dash-chamber, and dash-wings in the dash-chambersecured to the shaft suhstantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

CHRISTOPHER GULLMANN.
