BACKWATERiA ND SEWER-GAS TRAP.
SPECIFICATION forming art of Letters Patent o. 542,417, dated July 9,1895.
I Application filed November 21, 1894" Serial No. 529,439. (No model.)
To aZZ whom it may concern.-
Be it known that I, PHILIP F. LENHA RT, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Backwater and Sewer-Gas Traps, of which the following is aspecification.
This invention relates to certain improvements in sewer-traps of that class in which a swinging valve is used, which opens readily to interior pressure but closes tightly by gravity and exterior pressure, so as to prevent the ingress-of backwater'and sewer-gas, the trap being furthermoreso arranged as to be readily accessible forcleaning and repairs; and the invention consists of a backwater and sewer gas trap provided with a swinging valve, which is located. in an inclined guidebox that is formed of angular abutting flanges on the two adjacent pi pe-scctions of the valvecasings, said flanges being connected by bolts.
straight and enlarged top part for permitting the swinging of the valve which is hinged to an inclined valve-frame inserted in the guidebox, which valve-frame is made removable from the guide-box and formed of two sections,the inner one having aseat for the valve which is hinged to the upper part of the outer section, as will be fully described hereinafter.
In the accompanying drawings, Figure 1 represents a vertical longitudinal section of my improved backwater and sewer-gas trap. Fig.2 is a top view of the same. Fig. 3 is an elevation of the inner pipe-section, showing the valve-frame in partly raised position; and Fig. 4 is a side elevation showing the trap arranged on a smaller scale, so as to be used for sinks, basins, 85c.
Similar letters of reference indicate corresponding parts.
Referring to the drawings, a a represent the casing of my improved sewer-gas trap, which is inserted in the usual manner into the pipe connecting the sewer with the house, so as toprotect the same against sewer-gas and against overflow by backwater from the sewer. The valve-casin g is made of two pipesections a a", an inner section a. back of the valve B and an outer section a in front ofthe valve B. The sections a a. are united at a suitable angle of inclination to the longi tudinal axis of the trap by means of inclined angular flanges a which are connected at their upper and lower ends by screw-bolts a A suitable packing is interposed between the faces of the flanges at their sides and bottoms.
The inner section Ct of the valve-casing is made of a somewhat smaller diameter than the outer section a, which latter is enlarged at its upper part and provided with astraight inclined portion of, so as to give sufficient play for the valve B when the same is swinging into open position. The valve Bis hinged to eyes I) at the upper end of a valve-frame 0-0, which is formed of two sections, an'inner' section O, which is of the same diameter and'in line'with the inner pipe-sectiona of the valve-casing, and anouter section 0, which is in line with the inner surface of-the outer section a.- The inner sectionO' of the valve-frame is provided with a seat (1 of typemetal, while the valve B is made of composition that is not liable to corrosion by the action of fluids on the same. Both sections 0 O of the valve-frame are inserted into the open top part and supported by the sides and closedbottom part of theinclined guidebox formed by the angular flanges a. of the pipe-section a, a, the valve frame being tightly retained in the oblong opening formed by the inclined guide-box. The upper part of one of the sections is provided with a han dle h, so that when the connecting-screws a? are loosened the entire valve-frame can be readily removed, so as to permit the cleaning of the valve and its valve-frame, while giving access to the pipe-sections a a, so as to dispense with the hand-hole and handhole cover heretofore used in traps of this class, as the opening in the top of the guidebox a a is large enough to permit the intr0- duction of the hand and arm for cleaning the pipe-sections ct a, of obstructions or sediments. When any liquid is passed through the trap the valve is moved into open posivents the passage of backwater and sewergases into the service-pipes of the building. As the valve swings freely out of the way of the outflow, no sediments are formed around the valve which would prevent the proper closing of the same against backwater and sewer-gas. lhe valve can also be constructed on a smaller scale, as a trap for wash-basins, sinks, &c., in which case the connection of the pipe-sections, instead of being made by calking, as in large-sized traps, is made by unions with the connecting-pipes, as shown in Fig. 4. The same advantages result in this ca senan1ely, the convenience of removing the valve and its valve-frame, so as to give access to the valve and to the interior of the valve-casing for cleaning, and the reliability by which the trap accomplishes its functions of opening to the outflow of the drainage and of closing against backwater and sewer-gases.
As the valve proper is made of non-corrodible composition metal and the valve-seat of type-metal, the valve and the seat are not affected by the liquids and gases passing through the trap, and the same is rendered thereby much more durable than the castmetal valves used in sewer-traps heretofore.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination of a valvecasing, formed of an inner and an outer pipe-section, said pipe-sections being provided with exterior, angular flanges forminga guide=box open at the upper end, bolts for connecting said flanges, and a valve-frame inserted into the open top-part of the guide-box and provided with a valve-seat and with a valve hinged to the upper part of the frame, substantially as set forth.
2. The combination of a valvecasing, formed of an inner and an outer pipe-section, said pipe-sections being provided with exterior, angular flanges forming a guide-box, bolts for connecting said flanges, and a valveframe inserted into the open top-part of the guide-box and formed of two sections, the inner section being provided with a valveseat and the outer section with a valve which is hinged to its upper part, substantially as set forth.
3. The combination of a valve-casing, composed of an inner and outer pipe-section united at a suitable angle of inclination to the longitudinal axis of the casing, said pipesections being provided with inclined angular flanges abutting at the sides and bottom and being open at the top, bolts for connecting said flanges, a valve-frame guided by said inclined flanges, and composed of two sections, one section being of the same interior diameter as the inner pipe-section of the valvecasing, while the outer section is in line with the interior surface of the enlarged outer pipesection of the valve-casing, and a valve hinged to the upper part of the outer section of the valve-frame and adapted to swing in the enlarged upper part of the outer pipe-section, substantially as set forth.
In testimony that I claim the foregoing as my invention I have signed my name in prescnce of two subscribing witnesses.
