CHECK VALVE. No. 326,549. X Patented Sept. 22, 1885 f PE- E 17- I M INVENTUR'.
UNITED STATES PATENT OFFICE.
JULIAN DESTE, OF MEDFORD, MASSACHUSETTS.
CH EC K-VALVE.
SPECIFICATION forming part of Letters Patent No. 326,549, dated September 22, 1885.
Application filed November 19, 1884.
To all whom it may concern.-
Be it known that I, J ULIAN' DESTE, asubject of her Britanic Majesty, and a resident of Medford, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Check-Valves, of which the followingis a specification.
The object of my invention is to provide a check-valve so constructed and placed in the pipe that the valve and seat, although making an absolutely tight joint in said pipe, may be easily removed therefrom, when desired, without disturbing any portion of the pipe itself.
One form of my improved check-valve is shown in the accompanying drawings, in which Figure l is a vertical section of pipe and check-valve in position. Fig. 2 is a top plan of check-valve in position in the pipe, the pipe being cut in section on line y g of Fig. 1. Fig. 8 is a vertical section of pipe and check'valve on line :0 w of Fig. 1. Figs. 4 and 5 are details of check-valve and seat removed from the pipe. Figs. 6and 7 are details of a peculiarly-shaped wedge with two arms which hold the check-valve and seat in position in the pipe.
The same letters indicate similar parts in the different drawings. 7
A is that portion of a pipe, of metal or other suitable material, in which the check-valve and seat are to be placed. It is provided with the usual cap screwed on air-and-steam tight.
Blis the valve-seat, which has a smooth lower surface fitting closely to a corresponding annular surface in the pipe. The upper surface of the valve-seat is an inclined plane, and on this the valve 0 rests.
D represents two side lugs or shoulders formed 011 the inside of the pipe, and against (ModeL) them press the upper edges of the two-armed wedge E, the lower edges pressing against the outer rim of the seat B.
After the valve and seat are put inside the pipe in position through the opening covered by the cap before mentioned, the wedge E is put in and driven home, and, by the close pressure of its arms between the lugs D and the valve-seat B, holds the valve and seat firmly in place, making aperfectly tight joint.
When it is desired to remove the seat and valve for any cause, it is done by turning a screw, F, which is threaded through the central portion of the two-armed wedge E, and bears against the outer rim of the valve seat B. It is obvious that by turning this screw F inward toward the valve-seat, which resists all advance in that direction, the wedge E is drawn slightly outward, enough to relieve its pressure upon the lugs and valve-seat, and it may then be easily drawn out by hand.
The advantages of my improved check-valve would seem to be obvious without further explanation.
I claiml. A loose check-valve and seat hinged upon each other, formed separately from the pipe, and provided with a wedge, E,- for holding said valve and seat in the pipe to make a steam-tight joint, and a screw, F, for removing said wedge, as herein described and shown.
2. The two-armed wedge E, provided with the screw F threaded through the same, and a fixed bearing for said screw, as herein described, and for the purposes specified.
JULIAN DESTE.
