BACK-PRESSURE TRAP FOR SEWER-PIPES.
Specification of Letters Patent.
Patented Jan. 23, 1906.
Application filed August 15, 1904. Serial No. 220,705.
in the State of Missouri, have invented certain new and useful Improvements in Back- Pressure Traps for Sewer-Pipes, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to improvements in a back-pressure trap for sewer-pipes; and it consists in the novel arrangement, construction, and combination of parts, as will be fully hereinafter described, and set forth in the claim.
The object of my invention is to construct a trap to be placed in the basement or cellar of a building and located on the drain-line be tween the water-closets and sewer.
A further object of my invention is the automatic action of the trap, closing when a back pressure occurs and when open providing a clear unobstructed passage for the free discharge of drainage to the sewer.
A further object is the general construction of the trap, having a reach-opening directly above the automatic valve and a gate-valve in the delivery-pipe between the automatic valve and the sewer, the reach-opening covered with a spring-actuated plate adapted to be raised when the pressure is caused in the pipes by gas explosions, thus preventing breakagelto the pipes and trap-castings.
The mostyessential feature of my invention.
is the automatic closing of the trap by the backwater of a, sewer to prevent the flooding of the premises, and the gate-valve, which may be closed when it is necessary to repair the trap and its pipe connections.
Figure 1 is a vertical longitudinal sectional view of my improved trap. Fi 2 is a top plan view of the same, a part tflereof being broken away and in section. Fig. 3 is an end view of the gate-valve looking from the left-hand side of Fig. 1. Fig. 4 is a diagrammatic view showing my device in its relative position to the draining system.
In the construction of the device as shown I provide a pipe 3, its end 4 communicating With axpipe leading to the basement'or cellar floor and its end 5 supporting a gate-valve 6, which in turn forms the connection to the pipe 7 communicating with the sewer. 7
An opening 8 is formed in the top of the pipe 3, over which is mounted a casing 9, suitably flanged at the top and: bottom, and is covered with a plate 10, the contacting surfaces being suitably packed with packing material 11 and held together by bolts or studs 12, forming leak-proof joints. The plate is also provided with an opening 13, in which is swaged a tube 14, composed of non-corrodible material, its lower end 15 being sharp and acting as the valve-seat. The
purpose of the sharp surface is to out and dislodge from the valve such material as paper, straw, or the like and allow the valve to perfectly close. Upon the plate 10 and in alinement with the opening of the tube 14 is mounted a T 16, being securely retained in position upon the plate by the screws or bolts 17.
The upper end of the T 16 acts as the reachopening and is provided with a beveled face 18, in which is seated the plate 19; A boss 20 is formed on the plate 19 and a yoke 21 contacting with the flange of the T 16. The said yoke is provided with a screw 22, carrying a cap 23. Between said cap 23 and plate 19 around the boss 20 is a coil-sprin 24, the tendency of which is to normally old the plate in closed position.
To the member 25 of the T 16 is connected the water-closets 26. In the casin 9 is located the automatic valve 27 and va ve-operating float 28. The said valve and float are held in a suspended position within the casing by pins 29 and 30, supported by angles 31, secured to the under side of the plate 10, the
The float 28 is of an elongated design, as shown in Fig. 2, the purpose of which is to economize space and yet, obtain the proper rising properties. A block 32 is placed upon the wall of the casing 9 to the rear of the said float to prevent said float from back movement.
It will be observed that the space in the casing before the valve and the passage in the pipe 3 below the valve are free and unobstructed. Therefore the automatic action of the valve is always intact.
The gate-valve 6 consists of the outer cas ing 33, in which operates the gate 34, connected to the operatingrod 35, passing through a stufling-box 36. This gate 34 is provided with two wedge-shaped lugs 37, lo cated on the rear side thereof, and are adapted to come in contact with inclined surfaces 38, formed in the casing, to wedge the said gate against the surface 39 of the end 5 when said gate is closed. A strip of rubber 4.0 or
other soft material is located in the casing extending about half-Way around. This is to receive the end ofthe gate and cause a tight joint. It is also for the purpose should any small article, such as gravel, lodge upon the seat the rubber would give under the strain of the gate and also avoid a cavity for substances to lodge in. The rubber liner is also a valve-seat for one-half of the circumference of the edge of the valve.
The operation of my invention is as follows: Should at any time the water from the'sewer back up into the pipe 8 and rise in the trap, the float will rise, pressing upwardly upon the valve 27, bringing it in contact with the seat, and thereby automatically closing the trap, preventing the water and sewage from entering the closet and overflowing the basement. If at any time a back pressure should occur by the rising of the riveror a sewer of too small a capacity and the trap should have been removed for repairs, the attendant of the premises closes the gate-valve, thus doubly securing against overflow.
If it is desired to wash the basement-floor, the attendant removes the cover from the inlet 41, which is arranged flush with the floor, allowing the water to pass to the sewer. Again, should the remises be destroyed by fire and the cellar be flooded by water from the fire-hose the debris may be removed at gular flange supporting said casing, a cover provided with an opening located upon said rectangular casing, a valve-seat located Within said openin a IT-casing located upon said cover and in a inement with the valve-seat, a pair of angles suspended to the under side of said cover immediately to the rear of the valve-seat, a valve hingedly suspended from said angles, an elongated float, a pair of arms supporting said float and hingedly suspended to the angles, said'float arranged to come in contact with the underside of the valve to automatically close said valve by the flow of gater from the sewer, substantially as speci- In testimony whereof I affix my signature in presence of two witnesses.
