Specification of Letters Patent.

- Application filed January 18, 1915. Serial No. 2,962.

ToaZZ whom it may concern:

Beit known that I, EDWARD KENNEDY,-a-

citizen of the United States of America, and

a resident of the borough of the Bronx, in the city of New York, in the State of New York, have invented certain new and useful Improvements in Testing Devices for Wa- Xt'er Systems, of which the following is a specification.

This invention relates to means usable in the construction of buildings for testing the pipe systems thereof.

The object of the invention isito provide a device of this character usable in connection with the trap at the base of the sewer system and having valved connections with both legs of the trap, which facilitates-the drawing oif and discharge into the sewer of the test water after the testing operation is completed. In the drawings, Figure 1 is a front elevation of a house trap constructed according to my invention, with testing apparatus in-place; Fig. 2 is an end view thereof; and, Fig. 3 is a sectional view of a portion of my improved trap with testing apparatus re moved.

Similar reference characters designate corresponding parts throughout the several views. v

Referring to the drawings, and more particularly to Fig. 1 thereof. the invention comprises a house trap 1 at the lower end of the plumbing system. having an arm 2 connected to the house system, and an arm 3 connected to the street sewer, and provided respectively with inlet and discharge openings l and 5. The arm 2 is of a larger diameter than the arm 3 and the inlet opening el, and is preferably of the size known a to the trade as one size larger than the said arm 3 and inlet opening. Such construction allows of the easy insertion by the hand of a bushing,hereinafter more fully described, and also permits the trap to be readily cleaned by the hand. The inlet opening 4 is interiorly threaded, as at 6. and is provided with a flange 7, the said threaded portion having an inner diameter of a greater width than the inner diameter of the inlet' pipe 8, which is fitted and calked into the said inlet opening. When the construction of the'building and plumbing, system is completed, and it is desired to test the same, a reducing plug 9 threaded interiorly and exteriorly, and provided with anintegral nut 10 is inserted in the arm-2 through the open end thereof, and is screwed into; the

opening-3, first by hand, and then further screwed and tightened by a-ratchet wrench or the like.

An elbow feed pipe comprises the. following parts, or their equivalents, a horizontal Patented Oct. 5. 1915.

member 11, a vertical member 13, a connecting elbow joint 12, an extension 15 having a valve 16, and a T c'oupling l-lconnecting the extension 15 with the vertical member 13. An elbow discharge pipe 17 is provided with a mlve '18 and the horizontal arm thereof is connected with the elbow feed pipe, preferably by the-intermediate nipple of the T coupling 14, and its opposite end is arranged to discharge into the off or outlet leg of the U-shaped trap. These valved connections enable the elbow feed pipe to feed the test water to the house system. through the pipe 8 thereof when the valve 18 is closed and the valve 16 is open and in connection with the elbowdischarge pipe 17 to discharge the test water from the house pipe system into the off leg 3 of the trap and thence to the sewer when the valve 16 is closed and the valve18 is open. These various parts to be fitted into the trap may be very readily constructed from standard stock.

When it is desired to test .the system, the valve 16 is opened, the valve 18 .closed,-and water from the supply pipe is admitted through the bushing 9 into the system of pipes to be tested until the same are filled. When the test is completed, or if there are any repairs to be made, the valve 16 is closed, valve 18 opened, allowing the water to run out through the test fitting into the outlet leg of the trap to the sewer, and the repairs made if necessary. The system having been thus tested." the pipes and bushing 9' are removed, a bushing or bush-nipple 19,

having its inner diameter equal to that of the pipe 8, is screwed ,by hand into the opening 3, so as to give the inlet a smooth and unobstructed surface, and a plug 20 1s screwed, calked, or otherwlse secured, in the end of the arm 2, thereby closing the ends of the trap for ordinary use.

In this construction, I have provided a most practical and efficient testing means,

which a true testing may be -accome 'plished, there being no points to give way to pressure as in a device employing rubber or other such col'inections.

I have illustrated and described a pre ferred andsatisfactory lorm oi nrv invention, but it is obvious that changes ma be made therein within the spirit and scope tl'iereo'f, as defined in t1 3 appended claims,

and that the principle may be applied toother parts of the plumbing system.

I claim r 1. A device of the character described comprising a U-shaped trap. both legs of which are provided with nipples at their upper ends and with lateral nipples, the inlet leg being of larger diameter than the outlet leg, the lateral nipple of the inlet leg having a. screw-tln'ea(.led throat of larger diameter than the inlet pipe connected with said nipple, a testing apparatus comprising a reducing plug adapted to engage said throat, a T coupling, a pipe connecting Said T coupling with said reducing plug. a valved pipe adapted to connect said T coupling with-a water supply pipe and a 'alved pipe for connecting said T. coupling with the outlet legvot said trap.

A device of the character described comprising a U-shape trap, both legs of which are provided with nipples at their -upper ends and with lateral. nipples, the inlet leg being of larger diameter than the outlet leg. the lateral nipple oi the inlet leg having a screwthreaded throat of larger diameter than the inlet pipe connected with said nipple, a testing apparatus comprising a reducing plug adapted to engage said threat. a T coupling, a pipe con necting said T coupling with said reducing plug a valvedpipe adapted to connect said T coupling with a water supply pipe and a valved pipe for connecting said T coupling with the outlet leg of said trap, and a bushing interchangeable with said test reducing plug and adapted to make said threaded throat flush with the inlet pipe when the test device is not in use.

3. A device of the character described comprising a U-shaped sewer trap having lateral inlet and outlet openings on its respective legs: a reducing plug engaging said inlet opening, an elbow feed pipe whereof the horizontal member is connected with said plug within the inlet leg of said trap and the vertical member extends outward through the top of said leg, a valved discharge pipe connected at one end with said elbow pipe and delivering into the outlet leg of said trap, and a valved supply pipe connected with said elbow feed pipe above the connection therewith of said discharge pipe, said elbow feed pipe being adapted to supply test water to the pipe systembeing tested and in conjunction with said 'alved discharge pipe to deliver the test water from said system into the ott leg of said trap.

In testimony that I claim the foregoing as my invention, I have signed my name in presence of two subscribing Witnesses.
