Specification of Reis'sued Letters Patent. Reissued Aug. 27, 1907.

Original No. 846,600, dated March 12, 1907 serial 329,665. Application for reissue filed May 17,1907- Serial No. 374,311.

To all whom it may concern:

Be it known that I, BEN OAKES, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Water-Closet Bends, of which the following isna specification.

My invention relates to plumbing, and has particular reference to water-closets bends which make the i connection with and carry the soil from the closet-to' the soil-pipe stack, and is e e-constructed that it provides for the discharge of the waste from the bath-tub,

lavatory, sink, or other fixtures into the soil-pipe stack eitherwith a Y or '1 connection without danger of siphoning, as hereinafter set forth. I

A further object of my invention is to .provide a wator-closet bend constructed in such a manner that it provides for carrying the waste from lavatories, bathtubs, sinks, and the like into the soil-pipe stack and which bond shall be as substantial and sanitary as possible and at the same time .be readily adapted to various circumstances and conditions. Heretofore,

with a wiped joint.

. such as the settling of the soil-pipe stack or of the building or by expansion and contractiomof the bend, both hotand cold water being discharged into them. The work necessary in making these iorms of construction has a tendency to weaken the lead by overheating. i

With these and other objects in view my invention consists generally'of afcombination water-closet bend i withfiange arranged to receive soil and waste from water-closets, bath-tubs, lavatories, sinks, or other fix tures and to carry said waste direct to the soil-pipe stack with only one calked or'screwed joint without danger of siphon action one upon the other, and is also constructed that the floor connection can be: screwed in at any time before the floor is laid, thus avoiding danger of injury by plasterers and'other workmen before the floor is laid. i i Y My invention furtherconsistsin the-novel details of construction and in the peculiar arrangement and relative positions oftheseveral parts, all as hereinafter described and particularly pointed out. V q

My invention will be more readily understood by reference to the drawings hereto attached, in which:-

Figure li's a view perspective showing my in-' ventionwith the parts united. Fig. 2 is a sectional view of Fig. i. Fig. 3 is a sectional view of the enlarged end of my bend. Fig. 4 is an end view of the enlarged end. Fig. 5 is a sectional view of the bend, showing how the lead pipe is connected without a-soldered joint. Fig. 5 Fig 7,.is a section 'view'of Fig.8, which figure shows the eccentric form of the flange of my ben'd.

Similar letters refer to similar parts throughout the several views.

A is the water-closet bend and is preferably made of cast-iron of the same general style as to thickness and quality of iron used as ordinary "cast-iron soil-pipe. This bend is provided-with the waste-opening E, the said opening being threaded to receive the pipe-making connection for waste from other fi xtures than the water-closet. It will be noticed that the opening E is made on the top line of t ebend, and as the opening of the closet is of less capacity than that of the bend there .will always be an air-space at the top thereof, and the connections being made at the top siphoning will thus be prevented. An opening, preferably two inches in diameter, may be provided in the top of the bend 'for ,vent of closet wherever such construction is required or desirable.

strength at this point. This bead a is threaded on the inside to receive the brass flange B, which is also threaded. The outlet end'of the bend is intended to enter a T or Y in' the soil-pipe stack with a calked or screwed connection in the usual manner. I

The brass flange B, the construction of which can be varied and used in the form of a collar or thimble, has

7 the threaded extension b, as shown in Fig. '2, for the as only cold water passes the lead pipe C.

purpose of making a screw-joint connection with the inletend of the bend, the parts being screwed together with red or white lead to make a tight joint without the use of a washer. To the upper side of the brass flange B is attached the lead pipe C, which may be of any rcquiied length toextend far'enough above the floor to make'the usual opening for the closet. The Rad .pipe is connected to the flange B by means of the soldered joint D, which may be a wiped or sweated joint orof any approved'kind, and, if desirable, can be made at the lower'inside' end of theflange. The lead pipe C Y will take care of any slight settlement of the building'or soil-pipe stack or expansion and contraction of the parts,

'A somewhat less' expensivehjoint can be made and which at the same time will be substantialand' sa tary by the use of an'iron. flange, suchas isshownfih Fig. 6. When this is used, the lead pipe 0 is extended Fig. Gshowsthe form of flange used in...

The inlet end of the bend A is constructed with the heavy head 11, thus providing for additional through the flange and then turned over the extension b of the flange and up the side thereof, the said extension b in this construction being only about one-half threaded, the plain part thereof being somewhat reduced in diameterto form a recess d, into which the lead pipe (3 is fitted. The flange and lead pipe thus arranged are screwed into the bend A until the lead comes in contact with and is screwed tightly against the shoulder e at the neck of the bend, which is low- The lead is caught by the screwuse of white or red lead a tight permanent joint is assured.

In both forins of construction the flange is provided with the lugs c to assist in conveniently screwing the parts tightly'together.

Figs. 7 and Sshow a variationoimy invention, which allows of the-shifting of the position of the closet-opening. This is accomplished by constructing the flange C with the opening at one side of the center, whereby an eccentric is formed, and increasing the size of the inlet end of the bend to correspond'with the increased size of the flange so as to receive the same. The position of the load pipe can be varied to any desired point within the radius of the eccentric.

The flange B and the lead pipeO can be united with a soldered joint made at-the lower cnd of the extension b of the flange whenever suchgconstructior'i would be desirable. i

The enlarged end of the bend is "shown in Figs. 3 and 4. This construction provides for one or more waste connections other than from the closet and is constructed in such a manner that wi in one calked joint or screwed connection of the-bend with the'soilpipe stack two or more openings for waste are provided 4 I) I out danger ofsiphon action on the wasteconnections for and the waste conducted to the soil-pipe stack withirom the discharge of soil through the bend, as waste connections are run along the top or side of the outlet end of the bend, and by the use of the partitions G each waste-opening has direct and separate communication to the soil-pipe stack at all times. By making the proper and necessary connections with the chambers G this construction can also be used for vent purposes.

While I prefer the construction, as shown in the drawings, having the partitions G, still these partitions mayv bcndhaving the outlet end contracted but allowing sufficient capacity in the bend to take care of the waste from the closet.

The lower edge of the flange 6 determines roughly the level of the water in the bend A. Thus the level will be roughly as indicated by the dotted lines 9, g, leaving above the fluid in the bend an air space with which ,tially as described.

the opening E communicates, and into which air may pass from the delivery end of the bend, so that a siphoning action cannot take place in the auxiliary waste=inlets. Obviously the effect will be the same in the construction of Figs. 3 and 4, the same air space is secured reaching to the delivery end of'the bend.

The bend can also be made with the T'connection of the soil-pipe stack and the bend cast together in one piece, with a vent-opening in the top and nearthe outlet end of the bend.. By reducing the length of the,

outlet end of the bend-and providing it with standard screw-threads and other slight changes my improved bend can readily be adapted to be used in what is known among-plumbers as the Durham system. I I wish it understood that any or all of the inlet connections into the bend can be made by.use of a hub to receive a ferrule and calked joint in the place of screw connections, as herein shown and described.

Modifications of the.=minor details of my improved soil-pipe bend will doubtless readily suggest themselves to those skilled in the. art to which it appertains,

and I therefore do not desire to limit myself to the scribed. I I

Having thus described my invention,what I claim 1. A water-closet bend, its inlet screw-threaded to receivc a flange, the flange having an opening eccentric to the threaded portion to receive a pipe connection leading to a closet, the construction being such that a slight lateral adjustment of the pipe with reference to the closet and bend may be effected by rotating saidflange, substan- 2.
