BERNAT WEITZENHOFFER, OF EPERIES, AUSTRIA-HUNGARY.
STENCI-I-TRAP.
To all whom. it may concern:
Be it known that I, BERNAT VVEITZEN- HOFFER, subject of the King of Hungary, residing at Eperies, Austria-I-lungary, have invented certain new and useful Improvements in stench-Traps, of which the following is a specification.
This invention relates to a stench trap which is generally suitable for the outlet pipes of lavatory basins, slop sinks, urinals and the like. Heretofore such traps have generally consisted of U-shaped lead pipes, the great disadvantage of which is that they are diflicult to clean because the legs of the thin lead pipe forming the U and especially the horizontal part thereof passing into the wall, are more or less completely inaccessible through the small cleaning opening (usually closed with a screw plug) at the lower part of the U-shaped pipe. A further disadvantage is that the screw plug becomes corroded in time, and in order to loosen it so much power has to be exerted that the lead pipe is torn or otherwise injured; furthermore the lead pipe is liable to be distorted by pressure or by objects striking against it; and the connection becomes leaky when the cement connecting the trap to the lavatory basin or the like crumbles away. And finally such traps cease to act as such when the water seal is destroyed by the outflowing stream of water drawing the water out of the trap, thereby allowing of the escape of efliuvium or gas into the house.
The object of the present invention is to obviate these disadvantages, and for this purpose I provide the lower part of the trap box with a swinging stirrup or a screw after the swinging aside or loosening of which the bowls forming the waterseal and dirt collector can be removed and cleansed. When the outlet pipe is stopped, the said bowls can be removed and the pipe is then easily got at without disturbing the wall in the neighborhood of the lavatory basin or the like.
A further feature of this invention is that the trap box is all in one piece; owing to this fact the gas is prevented from escaping.
The waterseal is arranged in a special bowl which is not subjected directly to the outflowing stream of water, so that a breaking of the seal is not possible, whereby the escape of efiiuvium or gas is prevented.

show by way of examples different methods of carrying the invention into effect.
Figure 1 is vertical sectional view of one form of the invention. Fig. 2 is a like view taken at right angles to Fig. 1. Fig. 3 is a sectional view of a modification. Fig. .L is a horizontal section taken through Fig. 3.
The box 0 and the dip-pipe b are cast in one piece. In the annular space formed by these two cylindrical parts projects the bowl (Z which contains the luting or sealing water and serves partly as a dirt collector; the water Z lying between the lower edge of the clip-pipe b and the upper edge of the bowl d (see Fig. 1) forms the stench trap or seal. The bowl d is furnished with bearing surfaces fitting accurately against the lower edge of the box 0 with suitable jointing material, such as an indiarubber ring, for example, between them. The bowl d is con nected to the box a by means of the stirrup h and the screw 2' (the pointed end of which engages with a recess in the bottom of the dirt collector arranged at the lower part of the stirrup. The screws are let into corresponding recess in the box 0, while the legs of the stirrup are provided with holes the diameter of which is greater than that of the screws, so that the stirrup h, after the screw 2' has been slackened back can be swung in channels f of the projections e and the bowl (Z can be removed and cleaned. Not only can the trap itself be cleaned but also the outlet pipe m, which has heretofore been only partly possible. When the clean ing is completed and the parts d and 7 have been returned to their places the stirrup is turned back into its original position and fixed by means of the screw 2'.
In the arrangement shown in Figs. 3 to 4 the stirrup is omitted. In this case the bottom plate It rests on projection a of the box 0. The screw 2' passing through the bottom plate 7L projects into the thickened part of the bottom of the bowl and when screwed up effects the tight closing of the bottom of the trap. The opening of the trap is eifected by slackening back the screw 2' and turning the plate around about 45. The projections n of the bowl (see Fig. 1) come, when putting the trap together, opposite notches 0 in the box 0 and are then turned around about 45. This position is shown in dotted lines in Fig. 4. The screw bolt 2' passes through the bottom of the bowl cl, its head bearing against the inside of the I v of traps constructed in accordance with this invention is perfectly reliable, that the Water lute orseal cannot be broken because it is not subjected directly to the outfloWing stream, and consequently there is no sucking action destructive of the Water seal Z.
I claim p A device of the class described comprising an outer casing, having an opening in its bottom, a dip pipe projecting into said outer casing, and a bowl having its upper end surrounding the end of the dip pipe and located above the outlet of the outer casing and means for removably holding the bowl in the opening in the outer casing.
In testimony whereof, I aflix my signature in presence of tWo Witnesses.
