TRAP.

SPECIFICATION forming part of' Letters Patent No. 424,188, dated March 25, 1890.

Application led May Z3, 1889. Serial No. 311,867. (No model.)

To all whom it may concern:

Be it known that I, HENRY B. EARECKSON, of the city, county, and State of New York, have invented a new and Improved Trap, of which the following' is a full, clear, and exact description.

The invention relates to traps for sinks, bath-tubs, laundry-tubs, dac.; and the object is to provide a new and improved trap, which is simple and durable in construction andl very effective in operation, for discharging the refuse water, at the same time preventing any gas arising from the discharge from entering the building'.

The invention consists of details and combinations of the same, as will be hereinafter fully described, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a sectional side elevation of the improvement. Fig. 2 is a sectional plan view of the same on the line @c x of Fig. l, one of the glazed caps being removed; and Fig. 3 is a perspective view of a clip for holding` the valve in place.

The improved trap A is provided with an inlet-pipe B, connected in the usual manner certain parts and with a sink, bath-tub, laundry-tub, &c., andV into the said' pipe B leads an overflow-pipe C, also connected in the usual manner with the overflow of the article to which the inletpipe B is connected. The latter is provided with a sidewise-extending bend B, forming the lower end, the outer edge of which is slightly inclined, as is plainly shown in Fig. 1.

The bent end B of the inlet-pipe B passes through an aperture in the end D of an S- pipe D, having its other end D2 inclined downward and extending into the discharge-pipe E, leading to the sewer or cesspool.

On the outer inclined end B2 of the bend B is held an outwardly-opening valve F, provided at its upper end with a lug F', pivoted on a bolt G of the clip G, held on a rubber ring H, surrounding the end of the bend B extending into the end D of the S-pipe D. The outer edge of the rubber ring H extends slightly beyond the inclined edge B2 of the bend B and forms the seat for the valve F.

The latter is inclined at the same angle as the edge B2, so that the valve is seltolosing. The outer edge ot' the end D2 of the S-pipe D is similarly inclined, and is held closed by a valve I, similar in construction-to the valve F, being provided with a lug I fulcrumed on a boltuG(2 of a clip G3, similar to the clip G, and hold on a rubber ring II', surrounding that part of the end D2 extending into the discharge-pipe E. The rubber ring H forms the seat for the valve I, which latter, on aocount of being inclined as shown in Fig. l, is self-closing.

The distance that the bend B passes into the end D ot the S-pipe D is limited by an annular offset B3, formed on the exterior of the bend B', said annular oiset B3 abutting against the outside of the end D of the S- pipe D. In a similar manner an annular oitset D3 is formed on the 4end D2 of the S-pipc D, said offset abutting against the outside of the discharge-pipe E. In order to fastenthe inlet-pipe B, the S-pipe D, and the dischargepipe E together, I prefer to use solder J, placed between the pipes B and D and between the pipes D and E, as is plainly shown in Fig. l.

Int-o the end D of the S-pipe D leads a fresh-air-inlet pipe K, directly opposite the valve F. A foul-air-outlet pipe L extends from the upper end of the discharge-pipe E and serves to carry off the foul air and gases arising in the discharge-pipe- The top of the end D of the SpipeD is closed by aserew-cap N, provided in its middle with a glass cover O, which permits of examining the workings of the valve F without removing any ot' the parts. A similar screweap P is held on top of the dischargepipe E, and is also provided with a glass cover Q for examining the workings of the valve I.

The operation is as follows The discharge water passing into the inlet-pipe B or the overfiow-pipe C, leading to the said inlet-pipe B, fiows into the bent end B and by its pressure opens the valve F, so that the water iiows into the S-pipe D. In the latter .is formed the seal shown in dotted lines in Fig. l at a', so that the dischargewater passes through the bent part of the S-pipe D into the downwardly-inclined end D2, and by its pressure opens the valve I and iiows into the dischargepipe E. The moment the water discharged IOO into the inlet-pipe B has passed through its bend B the valve F again closes by its own weight, and in a similar manner the valve I closes after the discharge has passed into the discharge-pipe E. As the pipe K, leading into the end D of the S-pipe D, is connected with the fresh-air inlet, fresh air remains in J[he upper end of the pipe D. Foul air andv gases arising 1n the discharge-pipe E cannot pass into the S-pipe D, as the said pipe is closed bythe valve I. The foul air and gases, however, pass upward from the dischargepipe E into the foul-air-outlet pipe L, which extends upward, usually above the building in which the trap is used.

In the lower bent end of the S-pipe D is screwed a screw-plug R, serving to conven- Having thus fully described iny invention,

I claim as new and desire to secure by Letters Patentl. A trap consisting of an inlet-pipe B,hav ing its lower end B bent outward and provided with a valve, the pipe D, having a vertical member D', into the inner side of which said valved end I enters, the pipe D being curved inward and upward under the end'B and provided with an inclined discharge end D2, having a valve I, the pipe E, into the side of which the Valved end D2 enters, ventilating-pipes K L in the pipes D E in front of the valves F I, respectively, and I[he removable caps on the upper ends of the pipes D E over said valves, substantially as set forth.

2. A trap comprising an inlet-pipe having on its lower end aself-closiug valve, an S-pipe into one end of which discharges the said inlet-pipe, a self-closing valve held on the end of the said lS-pipe, a f1esh-air-inlet pipe opening into the inlet end of the said pipe, a discharge-pipe into which opens the valve of the said S-pipe, a foul-air-outlet pipe leading upwardly from the said discharge-pipe, and glazed caps held on the inlet end of the said S-pipe and on the upper endv of the said discharge-pipe, substantially as shown and described.
