STEAM-TRAP.
SPECIFICATION forming part of Letters Patent No. 600,279, dated March 8, 1898. Application filed July 2, 1897. Serial No. 643,267. (No model.)
To all whom, it may concern.-
Be it known that we, HUBERT EDSON and State of Louisiana, have invented certain new and useful Improvements in Steam-Traps, of which the following is a specification.
This invention relates to certain new and useful improvements in steam-traps adapted more particularly for use in steam and hotwater systems; and it is the object of the invention to provide a simple and efficient steam-trap which shall be automatic and certain in its operation and one which is not liable to get out of order.
\Vith this object in view the invention consists in the construction and arrangement of the parts hereinafter more fully described.
In the accompanying drawings, forming a part of this specification and in which like letters and figures of reference indicate corresponding parts, Figure 1 is a vertical sectional view of the invention, and Fig. 2 is a similar view on the line w 00 of Fig. 1.
Briefly stated, the invention consists of a receiver provided with a supply-pipe through which steam and water of condensation are supplied to the receiver and with a valvecontrolled discharge-pipe leading from the receiver to a boiler to which the hot water of condensation is to be conducted. The receiver is normally held suspended by means.
of an overbalance-weight or equivalent device, and the valve of the discharge-pipe is maintained in its closed position. The receiveris, however, capable of an up-and-down movement relative to the discharge-pipe to open and close the discharge-valve.
Referring more particularly to the drawings, A designates the receiver, which is of suitable shape and capacity and is pivotally connected at its upper end by means of a link 1 to one end of a lever 2,which is in turn pivotally connected intermediate its ends to a hanger 3. At its opposite end the lever 2 is provided with an adjustable overbalanceweight 4 or its equivalent-as, for instance, a spring-which weight is normally sufficiently heavy to depress one end of the lever 2 and elevate the opposite end, to which the receiver is connected, and thereby raise the said receiver.
' The receiver A is provided with a waterglass 5, by means of which the height of the I water contained therein may be ascertained,
and it is also provided with a detachable bottom or plate 6, provided with lugs 7 and with a central opening 8, surrounding which is a stuffing-box 9. Having its upper end extending through the central opening 8 of the plate 6 and projecting into the receiverAis an openended cylindrical casing (),and upon this casing the receiver is adapted to freely move.
WVithin the lower end of the casing G is a piston 12, surrounded by a stuffing-box 13, which piston constitutes a pressure-equalizer to compensate for the difference in area between the upper and lower ends of the receiver, and'the lower end of the piston bears upon a yoke 10, the arms of which are connected to the lugs 7 of the receiver A.
Leading from the receiver A is a dischargepipe D, which extends to a boiler or to any other desirable vessel. Preferably, though not necessarily, this pipe projects into the receiver, as shown, and is connected to the easing 0, through which it extends longitudinally, the exterior diameter of the dischargepipe being, however, less than the interior diameter of the casing to permit the free inflow of steam and water through the casing into the receiver. The discharge-pipe D is provided at its upper end with a valve-seat, with which cooperates a suitable valve to control the outflow of water from the receiver. As illustrated, the pipe is provided with two diverging branches 14 15, which are connected at their upper ends by means of a horizontal section 16, provided in its upper and lower sides with alining ports 17 and 18, having seats for suitable controlling-valves 19 20. By thus arranging the discharge-ports the water is allowed to flow more freely from the receiver than if a single port were provided, as any air or steam which may be combined with the water is permitted to freely escape to the upper end of the receiver. It will be obvious, however, that a single valve and port may be employed in some instances. The valves 19 and 20, together constituting a balance-valve, are mounted upon a vertical stem 21, carried by an inverted-U-shaped support 22, which extends between the branches 14: 15 of the discharge-pipe below the horizontal section 16 and is in turn connected to the receiver A to move therewith, and, preferably-the: support 22 is carried upon the detachable bottom of the receiver. One of the valves 19 is arranged within the horizontal section 16 and the other beneath the said section in position to close the ports 17' and 18 when the receiver is" elevated and to open said ports when the receiver is lowered in the slightest degree.
In operation the weight 4 is adjusted upon its lever to maintain the receiver elevated until a predetermined amount of Water is accombined-weight of the receiver and the water contained therein, lifts the receiver and forces the discharge-valves to their seats to close the discharge-pipe.
From the above it will be'apparent that a steam-trap is provided which-is not only simple in construction and absolutely-certain in operation, but one in which theuse of floatvalves and delicate mechanism that is liable to get out of order is dispensed with.
It will be'noted, moreover, that the discharge-valves and their cooperating devices are connected to a'single plate, which is made detachable fromt-he receiver-to render all ofthe parts 4 easy of access.
It will 'be obvious that while the dischargepipe is describedas being stationary and the valves controlling the discharge-ports as 'being carried upon the receiver to move there-, with the discharge pipe may be supported upon the receiver and the valves carried upon the stationary base withoutvdeparting' from the scope of the invention, and it will also be obvious that the inlet and discharge pipes may enter the receiver through the top thereof as well as through the bottom, as shown.
Without limiting ourselves to the precise construction and arrangement of parts shown,
-we claim as our invention- 1. In a steam-trap, the combination of a vertically-movable receiver provided with an inlet, a stationary discharge-pipe extending into the receiver and having a horizontal portion at its upper end provided with a port,
and a valve carried upon the receiver and adapted to'control the port of the dischargepipe, substantially as described.
2. In a steam-trap, the combination'of a vertically-movable receiver provided'with an inlet and with a detachable plate, a "station- 'ary "discharge pipe extending into thereceiver; said? pipe being provided with a port, and a valve connected to thedetachable plate and adaptedlto control the' port of the'discharge-pipe, substantially as described.
. 3.'-In a steam-trap, the combination :of a vertically-movable receiver provided in its bottomwith an inlet, having a pressure-equal- -izer, and a valve-controlled discharge-pipe leading from the receiver, substantially as described.
4. In a steam-trap, the combination with a vertically-movable receiver, of a stationary cylindricalcasing extending into the receiver,
an inlet-pipe communicating with the'casin g,
-astationary discharge-pipe likewise extending into the receiver, and a valve operated by the movement of the'receiver to control thepassage of said pipe, substantially as-described.
In testimony whereof We have signed our names to this specification in the presence of two subscribing witnesses.
