LIFT-VALVE AND lTSGUAR D FOR GAS AND LIQUID PUMPS.
- in Lift-Valves and Their Guards for-Gas and Liquid Pumps, of which the following is'a specification.
This invention relates to improvements in and relating to lift valves and to guards therefor for use in pumps dealing with gases and liquids, and is designed to render such. valves more ellicient, lighter, and'less costly as alsomore reliable against breakage and leakage. I
In the accompanying drawing which illustrates the invention and in which like parts are similarly designated Figure 1 is a vertical section of one form of the improved lift valve and guard; Fig. 2 is a like view but showing a modification; Fig. 3 is a plan of the valve; Figs. at and 5 are vertical section and plan respectively of a further modification.
According to the invention the valve A is, in the caseof all the constructions shown, formed by pressing, stamping or spinning from metallic sheets or from a forged disk of ductile material. The sectional form of the valve is as shown that of an annular ring with a groove or arched passage B formed between the two seating. faces D. The outer wall 0 of the passage-B is utilized in conjunction with the during its lift.
Referring to Fig. 1 the improved guard F guard F for guiding the valve is as above mentioned formed by pressing,
stamping or spinning from a metallic sheet or from a forged disk of'duct-ile material, an annular disk with a central flat portion or depression G be tween which and the circumference of the disk an annular passage H is formed by the downward Hanging of the outer circumference. The circumferential flange or wall J forms-the guide for the valve A and the crown K of the annular passage H forms the stopper for limiting the lift of the valve.
According to the construction of the guard 1 shown in Fig. '2 there is formed between the central flat portion G and the outer circum- 1 ferential guiding wall or flange J an additional annular arched passage H into which can be placed a SPIIDT L bearing on the 5 crown of the passage or arch.
In both constructions the guard F is se- Speciflcation of Letters Patent.

cured to the seat'D by means of a screwed stud or studs M fixed in the seat and projecting through the flattened central part G of the guard F and held by means of a nut M Openings N are made in the guard F between the flange J and the central portion G to allow free passage for air or liquid.
According to the modification shown in Figs. 4 and 5 the guard F is formed as an annular ring having a depression G between two arched passagesH substantially of the same contour as that shown in Fig. 1. This arrangement provides a guard for two annular valves A. In this case the guard F is alsoheld in position by thestuds M in the the crown of the passage B is semi-circular and the guiding wall C is curved slightly, the curve preferably being of a diameter approximately equal to the diameter of the guiding wall itself. This prevents any tendency for the valve to become jammed in the guard. F.
Having now described my invention, what I claim and desire to secure by Letters Patent of the United States is 1. The combination with two concentric annular valves, said valves each presenting in vertical section a form comprising two flat seating faces joined together by a groove or arched passage, of a single valve guard formed to provide a central flattened depression for permitting its attachment to the valve seat, and with an inner and outer flange or guiding wall for guiding the valves during their lift with crowned passages between the central depression and the guiding flanges for limiting the lift of the valves.
2. The combination with a valve seat having two concentric series of openings, of two concentric annular valves,- each adapted to close one of said series of openings, and an annular valve guard having a portion adapted for attachment to said valve seat and a depending annular flange on either side of said portion, said annular flanges being constructed and arranged to guide said valves during the lift of the latter. I
3. The combination with a valve seat having two concentric series of openings, of two IIO 4 having a portion ada ted for attachment to "ed to engage said raised portions of said ries of openings, and an annular valve guard valves to limit the lift of the valves. I
4. The combination with a valve having a 1 portion taised above the seating portion thereof, of a valve guard having a depending portion arranged to co-operate With the raised portion of said Valve to guide the latter during its lift, and means, carried by said depending portion above the lower edge th'er'eof, adapted to engage saidraised tion of said valve to limit the lift of the latter prior to the engagement of the seating portion of the valve with the lower ed'ge'pf the 'de ending-portion of said valve guard. v
n testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
