STEAM TRAP.
APPLICATION FILED 00119, 19.08.
920,552 Patented May 4, 1909.1
To (LZZ whom it may concern} lie it known that I, NORMAN ENGLISH, a citizen of the United States, residing at De troit, county of lVayne, State of Michigan, have invented a certain new and useful Iniprovement in N on-Return Steam-Traps, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
This invention relates to steam traps, and has for its object an improved deviceof the type especially known as non-return traps,
ding of the steam system of the water of coi'ulensation with as little loss of steam pressure as possible.
in the drawings :-Figure l, is a side elevation of the device, showing, diagrammatically, the various pipe connect-ions with the coil and boiler. Fig. 2, is a detail of an improved type of steam valve, which 1 consider preferable, though not essential.
n represents the fixed tank, into which water of condensation is conducted from the steam coils through the medium of the pipe Z). the tank being preferably supported some distance above the base (Z by means of brace pieces 0. ater escapes from the tank through the pipe 6 which leads from a point within the tank somewhat above its bottom portion the overflow passes therethrough and through the lower section it of the flexible hose leading to the movable tank g. This tank becomes over weighted, and falls somewhat, causing the opposite weighted end of the pivoted lever is from that to which it is attached to rise, thereby actuating the link f, and raising the free end of the lever m, s which is pivoted at a, and when actuated, is held down by the weight Z. This in turn results in raising the stem 79 of the valve 0, and causing its piston q to unseat from the valve seat 3. As soon as the valve therethrough, both from the lower portion of the pipe 6, and from the movable tank 9 through the hose section it. Slight though the quantity of water thus released is, its 54 release almost immediately makes possible a the rise of the tank 9 and the closure through the lever and link members, of the valve 0.
w The water of condensation thus released :1 passes out through the pipe 2? to the sewer, p and the steam system is thus relieved of its Specification of Letters Patent.

STEAM-TRAP.
Patented May 4, 1909.
tank is relatively very slight, but almost constant, so that the effect is a very frequent though very slight, lifting of the valve disk from its seat 8, so that the flow is slight but almost constant. Preferably a gage glass w is attached to and connected with one end of the tank a. The upper flexible hose section a insures an equality of air pressure above the masses of water in the fixed and in the movable tank.
lV hat I claim is:
1. A non-return steam trap, comprising a fixed tank, a movable tank, a pivotally supported lever on one end of which said mov able tank is supported, a weight on the other end of said lever, whereby the tank when empty is held in raised position, flexible hose connections between the two tanks, an inlet pipe leading into the fixed tank, an outlet pipe rising from connection with the lower one of said hose connections to a point within the fixed tank, a valve controlling the flow therethrough, a pivoted lever weighted at its free end whereby said valve is normally held closed, and a link connection between said last named lever and the tanksupporting lever whereby any movement of the tank due to its filling with water from the fixed tank and the consequent movement of its lever is communicated to said last named lever to effect the actuation of said valve, substantially as described.
2. In a steam trap, in combination with a fixed tank adapted to receive the water of condensation from the steam coils, an outlet pipe therefrom having its upper end rising above the level of the bottom of the tank, a pivoted lever, a movable tank supported on one end thereof, a weight on the opposite end of said lever for maintaining said movable tank at the upper limit of its intended path of travel, fiexible connections from said movable tank to said outlet pipe and to said fixed tank, a valve controlling the flow of {further presence. The movement of the l let pipe, a weighted lever whereby the valve is normally held closed, and a link between it and said first named lever whereby any movement thereof due to the travel of said movable tank is communicated to it and the valve is thereby caused to open, substantially as described.
3. In a steam trap, the combination of a fixed tank, a pipe leading thereinto from the steam coils, an outlet pipe, a valve controlwater through the discharge end of said outling the flow through said outlet pipe, weighted lever for actuating said valve and for holding the same normally closed, a sec ond weighted lever linked to said first named lever, a movable tank supported on the unweighted end of said second lever, and pipes connecting the same with said fixed tank whereby water may be led thereinto from the fixed tank and its supporting lever thereby actuated to in turn cause an opening of the valve, substantially as described.
4. In a steam trap, the combination of a fixed tank, a movable tank, flexible hose connections therebetween, an inlet pipe leading into the fixed tank, an outlet pipe extending from the interior of the fixed tank, its outer portion being connected with one of said flexible hose connections, a valve controlling;
a l the flow through said outlet pipe, a pivoted lever on one end of which said movable tank is sup 'iorted inv normally raised position, a second lever whereby said valve is actuated, a weight on the free end of said second lever whereby said valve is normally held closed, and a link connecting said last mentioned lever with the tank-supporting lever, whereby the free end of the latter is normally held in depressed position, substantially as described.
In testimony whereof, I sign this specifi cation in the presence of two witnesses.
