sack-WATER SEWER-VALVE.
Specification of Letters Patent.
Patented July 1?, 1917..
To all whom it may concern:
Be it known that we, GEORGE L. MULLANE and ALBERT C. EKMAN, citizens of the United States, residing at Minneapolis and Robbinsdale, respectively, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Back-VVater Sewer-Valves, of which the following is a specification.
Our invention relates to back Water sewer valves and has for its object to provide a' valve for attachment in a sewer outlet of any building or part thereof which Will have the effect of shutting off back flow through the outlet pipe due to excessive rains, clogging of the main sewer or other causes.
In carrying out our invention we have applied novel and particularly efficient means to the making and assembling of the valve mechanism and to the organization and arrangement of out-let and inlet pipes connected with the valve. We have also devised eflicient means for forcing the valve member into position to break sticks and squeeze out obstructions which may have accumulated between the valve member and its seat.
The full objects and advantages of our invention will appear in connection with the detailed description thereof and are particu larly pointed out in the claims.
In the drawings, illustrating the application of our invention in one form,
Figure 1 is a longitudinal section through the valve. Fig. 2 is a transverse section viewed toward the front of the valve.
As illustrated, the device comprises a casing 10 having an inlet 0 ening 11 adapted to communicate with the discharge pipe of the building in the usual way. The casing comprises an inner flange-like structure 12 having a shoulder 13 with a circular seat 14 surrounding said shoulder and turned toward the discharge side of the pipe. Below the circular seat 14 the casing drops down, as indicated at 15, and the discharge pipe 16 to the sewer extends from that level. Above the depressed portion 15 and seat 14 the casing is formed in a circular ring 17 surrounding a clean-out opening 18 which is normally closed by a plate 19 bolted to the ring 17, the opening 18 being above the depressed entrance to discharge pipe 16.
Within the seat 14 is secured a removable ring 21 preferably of brass or some other material than cast-iron. The ring 21 has rigidly connected therewith a lug 22 to which is pivotally connected by means of hinge members '23 a swinging valve 24. This valve is adapted to cooperate with a seat 25 on the exposed edge of ring 21 so as to close the opening from passageway 11 when there is any back flow through pipe '16. The ring 21 is secured within the seat 14 in contact with the shoulder 13 by the use of oakum and melted lead or solder. This attachment of the ring 21 may be easily effected by the introduction of the oakum and lead through the opening 18 and the discharge pipe 16.
Above the discharge pipe 16 the flange 17 is thickened to form a supporting rib 26 within which is secured a screw plug 27. The screw plug 27 is threaded and has therein a threaded portion 28 of a stem 29 having thereon a hand-wheel 30. The stem 29 is made water-tight by means of a packing cap 31. By rotation of the stem 29 the same may be forced into engagement with the valve 24 opposite a thickened portion 32 on the front of said valve. By this means the valve may be closed down upon the seat 25 on ring 21 so as to break off and squeeze out any substance, such as a piece of pencil, wood or paper, which may have lodged between the seat 25 and the valve 24. In this connection it is important to note that the discharge point from the pipe 11 into the outlet pipe 16 over the lower portion of seat 25 is considerably above the bottom of dis charge pipe 16, thus generally insuring the removal of material from inside of ring 25 so that the valve 24 will operate effectively. With this arrangement it will very rarely happen that any obstruction gets between the valve and seat 25; and if it should happen, the stem 29 will readily remove it. If the stem 29 is manipulated occasionally during the summer months the valve will always be in working order. Furthermore, if during a storm it should be found that the valve had not closed and water was backing up into the pipe, the operation of the stem 29 will quickly remedy the difiiculty, when the stem can be turned to nonengaging position and the back pressure will hold the valve closed. The cover 19 may readily be removed at any time to permit exhaust to the valve for cleaning out the trap below the same or repairs.
' We claim:
1. A back water sewer valve having a casing adapted to be positioned substantially horizontally in asewer, said casing providing an inlet passageway, and an outlet passageway at a lower level, with a vertical abutment and a free swinging normally vertical valve in the plane of junction of the inlet and outlet- 1 passageways, said passageways otherwise being free and unobstructed,
- and manually controlled means for seating said valve against obstructable material ll tending to hold it open.
2. Aback water sewer valve having a cas- .ing the ends of which are adapted to engage with the ends of a sewer pipe, a recess within saidcasin'g, a valve seat inserted within said recess, the joints between said casing -and said valve seat being packed with oakum GEORGE L.
