I SEAL DEVICE FOR SEWERS.
SPECIFICATION forming part of Letters Patent No. 498,121, dated May 23, 1893. llp licationiiled JulyZ, 1892. Serial No. 438.825. on model.)
To all whom it may concern:
Be it known that we, DAVID F. L. JONES and JOHN D. MOPHAIL, of Columbus, in the county of Muscogee and State of Georgia, have invented certain new and useful Improvements in Seal Devices for Sewersyandwe do hereby declare thefollowing to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
Our invention relates to an improvement in sewers, and more particularlyto an improved vseal device for sewers,the object being to produce an automatically operated valve for catch basins of sewers, by means of which accumulated water Will be automatically discharged into the sewer and the escape of sewer gas prevented.
A further object is to provide valve mechanism for the catch basin of a sewer, which shall be automatic in its operation, simple in construction and effectual in the performance of its functions.
With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts as hereinafter set forth and pointed out in the claims.
In the accompanying drawings: Figure 1 represents a sectional view of a catch basin having our improvements applied thereto.
Fig. 2 is a plan view. Fig. 3 is a View partly in section illustrating a modification of the valve.
A represents aportion of the wall of a sewer, and B an opening therein which is covered by means of a cover or. grating O of any preferred form of construction. Located in the opening B below the grating O, is an eye pipe D having a flange a adapted to be embedded in the brickwork A of the sewer as shown in Fig. 1. The pipe D projects downwardly into the sewer andis beveled atits lower end to produce a valve seat 19. Projecting upwardly from the top of the pipe D are brackets c, in which a shaft d is journaled, said shaft carrying a grooved pulley E, over which a rope or chain E passes. To one end of the rope or chain E, a conical valve F is attached as shown in Fig. 1, said valve being adapted to or chain E.
bear against the valve seat I) at the lower end of the pipe D and thus normallyclose the lower end of said pipe, being-retained normally in suchposition by means of a counterbalance weight F secured tothe other end of therope 7 Lugs e project from the lower end of the pipe D at diametrically opposite points,to which lugs bell-crank levers or latches Gare pivotally connected. The downwardly projecting arms f of the levers or latches G are recessed on their inner faces and adapted to engage the valve F and assist in retaining it to its seat, the properengagementand pressure of the arms f of the latches against the valve being maintained by means of weights 9 at the extremities of the laterally projecting arms f of the levers or latches G.
Now when, from rain or other cause, water pours into the pipe D, gradually filling it, the weight of the water increases, until, together with the weight of the valve, it balances the counterweight F, and the valve is then held to its seat only by the latches G. As the water continues to increase in quantity and weight, the latches G suddenly give Way under the strain, releasing the Valve F, which at once descends and allows the Water to escape into the sewer. The weight F then descends, drawing the valve back to its seat (the wheel or pulley It being caused to turn as the valve rises or falls) and the latches G going back to their places as the valve re-seats itself. Inasmuch as at the moment of the shutting of the valve, a little water remains within the pipe D,this water draining down into and accumulating in the wedge-shaped annular space at the bottom of the pipe and above and around the cone valve, becomes a sealing medium so as to prevent the upward escape of sewer gas. 7
Instead of constructing the valve F as shown in Fig. 1, the periphery of the valve may be provided with an annular recess h in proximity to its base, and in this recess a ring of rubber or other suitable packing material h may be inserted and adapted to bear against the valve seat at the lower end of the pipe D, thus insuring a tight joint between the valve and its seat.
Slight changes might be made in the details of construction of our invention without departing from the spirit thereof or limiting its scope. Hence we do not wish to restrict our selves to the precise details of construction herein set forth, but,
Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-
1. The combination with a sewer eye-pipe having a valve seat'at its lower end, of a conical valve adapted to normally bear against said valve seat,a counterbalance weight connected with said valve and weighted latches adapted to engage the valve, substantially as set forth.
2. The combination with a sewer eye-pipe having a valve seat at one end, and a counterbalanced valve adapted to bear against said valve seat, of latches, one arm of said latches being adapted to engage the valve and the other arms provided with weights whereby to normally uphold the valve to its seat, substantially as set forth.
3. The combination with a sewer eye-pipe having a valve seat at its lower end and a counterbalanced valve adapted to engage said valve seat, of lugs projecting from the lower end of said eye-pipe, bell-crank levers or latches pivotally connected to said lugs, one arm of each of said levers or latches being adapted to engage the valve to retain it normally to its seat, and a weight at the free end of the other arm of each lever or latch, substantially as forth.
In testimony whereof we have signed this specification in the presence of two subscribing witnesses.
