WASTE-TRAP.

Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed June 1, 1905. Serial No. 263,286. I

T0 at whom it may concern.-

Be it known that LALBERT S. Nnwroma citi- Zen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in WVaste-Trapaof which the followingis a specification, reference being had therein to the accompanying drawings.

My invention relates to sanitary or waste traps of all kinds, and has for its objects the ends commonly sought in structures of such a character, but more particularly to provide a perpetual and eflicient water seal against the accumulation and escape of gases in nonventilated traps.

To the above ends my invention consists in the novel internal flange and its relation to the various parts of the trap hereinafter described, and illustrated in the accompanying drawings, wherein Figure l is a vertical central section of a trap embodying my invention; Fig. 2, atrans' verse section of the same on linew w ofFig. 1; Fig. 3, a vertical section of the seal-flange and adjacent parts; Fig. A, a like section of the same when an auxiliary ring is employed. Figs. 5 and 6 are vertical sections of modified forms of traps embodying my invention.

Like reference characters indicate like parts throughout the views.

In the drawings, A represents the body of the trap, and B the inlet and G the outlet ducts or pipes.

D is the cap, havingits inner margin thread-7 ed to engage the threads upon the exterior of the upper margin of the body, thereby producing a joint (0. Upon the body exterior below the joint a projects an upright extension-collar 6, intermediate which and the lower edge of the cap D is the packing c. The collar 6 may be either connected with or cast to the body of the trap, its purpose being to prevent leakage of water upon the ceiling or parts below when occasion arises to remove the cap D. Extending from the inner margin of the body at its upper extremity, adja cent the joint (0, is an upwardly-inclined aunular flange E, which produces, in conjunction with the wall of the cap D, asubstantially V- shaped receptacle (Z.

F is the usual partition, whose upper end must lie in a plane not lower than the horizontal plane of the flange E; but in actual practice I find the best results attained when the partition extends slightly above the flangeplane. The partition is diametrically disposed in relation to the trap-body and rises from the baflie-plate G.

H is a horizontal shelf above the inlet-pipe, and I an extension of the vertical partition F.

The parts H and I are not essential to my trap and may be omitted, as shown in Figs. 5 and 6. In fact, my invention is equally operative in a structure like that shown in Fig. 6, wherein is substituted for the partition and baffle-plate a continuation of the outlet-pipe G into the trap, its upwardly-curved end F lying in the same or a higher horizontal plane than that of the flange E. The curved pipe end F may be provided with the exterior collar or guard-plate 6.

While my invention is shown embodied in a brass or hard-metal trap, it is obviously as applicable to a lead structure. In the latter case, however, the cap D is screwed to an auxiliary eXteriorly-threaded hardened ring m, soldered to the body A, as shown in Fig. A. The ring at is described in detail in United States Letters Patent to me, No. 698, 217, dated April 22, 1902.

The course of the water as it passes through.

the trap is indicated by the arrows in Figs. 1 and 6. When the water overflows in its ascent the upper edge of the partition F, it of necessity enters the annular pocket d and remains therein, as shown in Fig. 3, even after or when the water in the body of the trap has reached a lower level. The pocket d is therefore always filled with water and is a sure seal to the joint 40 against the escape of gases.

What I claim is 1. In a waste-trap, the combination with the body, the cap upon the body, and the vertical partition traversing the body below the cap, of an upwardly-inclined flange upon the interior of the body adjacent the cap, the free margin of said flange being in the same horizontal plane or lower than the top of the partition.

2. In a waste-trap, the combination with the body, the cap upon the body, and the curved ICO extremity of the outlet-pipe, of an upwardlyjoint, and an upright extension-collar upon inclined flange upon the interior of the body the exterior of the body below the joint. 0 adjacent the cap, the free margin of said flange In testimony whereof I have affixed my sigbeing in the same or lower horizontal plane nature in presence of two witnesses.
