STEAM TRAP.
AIPLICATION FILED MAY 20, 1905.
mvrrnn STATES STANL EY BEZVODA, OF BALTIMORE, MARYLAND.
STEAM-TRAP.
Specification of Letters Patent.
Patented Nov. 21, 1905.
Application filed May 20, 1905. Serial No. 261,456.
To whom, it may concern:
Be it known that'I, STANLEY BEZVODA, a citizen of the United States, residing at Baltimore city, State of Maryland, have invented new and useful Improvements in Steam- Traps, of which the following is a specification.
My invention relates to an improvement in steam-traps; and the object of my invention is to provide a trap in which the valve controlling the discharge of water or steam is held closed until the water rises sufficiently high to fill the float, whereby to cause the float to fall, thereby opening the dischargeopening.
The invention consists of certain other novel features of construction and combinations of parts, which will be hereinafter described, and pointed out in the claims.
In the accompanying drawings, Figure 1 is a sectional view of my invention. Fig. 2 is a top view, and Fig. 3 is a detail.
A represents the shell or body of the trap su ported on standards 1, and B is the cover. The shell or body and cover are provided with flanges 2 and 3, respectively, which are securely held together by bolts 4 4, and a packing 5 is placed between the flanges to form a steam-tight joint.
A steam-inlet C enters the body or shell A, and steam entering said opening impinges against a baffle-plate 6, projecting from the upper side of the shell or body, and is deprived of a large portion of water of condensation which it holds in suspension. The cover B is provided with a discharge-opening D for the escape of the steam by means of a suitable valve.
In the shell or body A is a float E, having a valve-rod 7 secured thereto by any suitable means, which valve-rod is guided in its movements in a pipe 8, secured in an opening 9 in the cover B.
In operation the steam or water entering the inlet C passes into the shell or body A, which after reaching a certain point begins to fill the float E through the opening 10, as well as at the top. When the float begins to descend, it opens the valve-opening 1 1, allowing the ball-valve 12 to follow the valve-rod 7 in its descent, thereby permitting the escape of the steam through the outlet D. The air-cock 13 is placed on the cover B to allow the escape of air from the shell or body. A cap 14 is also removably secured on the cover to permit of the placing of the pipe 8 and valve-opening 11. On the bottom of the shell or body is an opening 15 for draining the trap, and a nut or similar means is screwed in the opening when the trap is in use.
Slight changes might be made in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the exact con' struction herein set forth; but,
Having fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is a 1. A steam-trap comprising a shell or body portion having a steam-inlet, a cover provided with a discharge-opening, a pipe depending from the cover, the upper end of the pipe having a cap thereon with a valve-opening located therein, a valve-rod fitted to the pipe, a ball-valve between the upper end of the rod and the opening and a float secured to the lower end of the valve-rod.
2. A steam-trap comprising a shell or body portion having a steam-inlet therein, a cover secured to the shell or body portion, a cap having a screw-threaded orifice therethrough, a pipe screwed into the orifice and depending into the shell or body portion at its lower end and projecting above the cover at the upper end, a cap screwed to the upper end of the pipe and having a valve opening therethrough, a valve-rod fitted loosely within the pipe and carrying a float, a ball-valve interposed between the upper end of the valvestem and the cap, a cover having a dischargeopening and a cap removably secured on the cover to permit of the placing of the pipe in the orifice in the cover.
In testimony whereof I affix my signature in presence of two subscribing witnesses.
STANLEY BEZVODA.
