SINK TRAP AND LIFT.

Application filed April 9,

T all whom it may concern:

Be it known that I, JOSEPH A. OLAUGH- LIN, a citizen of the United States, residing at Hutchinson, in the county of Reno and State of Kansas, have invented certain new and useful Improvements in a Sink Trap and Lift, of which the following is a specification.

This invention appertains to novel improvements in combination water traps and lifts and the primary object of the present invention is to provide novel means for lifting water from waste traps in basements and the like to the sewer pipe, said means including a novel device for automatically preventing the backing up of the water in the trap and the consequent flooding of the basement should the sewer become stopped up or in any other way rendered unfit to carry away the sewage.

Another prime object of the invention is the provision of an automatic lift for water traps including a novel valve arrangement so constructed as to permit the flowing of the water up past the same to the sewer pipe but prevent the downward flow of water past the same into the trap.

A further prime object of the invention is the provision of a drain of a non-automatic or of an automatic construction within an airtight casing connected to a laundry drain or cesspool for facilitating the lifting of the water for a considerable distance above the laundry drain or cesspool.

A further prime object of the invention is the provision of novel means for changing the drain either into an automatic device or into a non-automatic device, the drain when constructed to work a-utomatically embodying a valve controlled float, which is arranged to operate to shut off the con-- nection between the drain and the trap when the water in the trap falls below a predetermined level.

A still further object of the invention is to provide an improved device of the above character, which will be durable and eflicient in use, one that will be simple and easy to manufacture, and one which can be incorporated in a plumbing system at a small cost.

With these and other objects in view, the invention consists in the novel construction,

arrangement and formation of parts, as will be hereinafter more specifically described, 5 claimed and illustrated in the accompanying drawings, in which drawings:

Figure 1 is a fragmentary side elevation of my improved drain and trap connected with a plumbing system, the drain being shown of a non-automatic construction, the trap being shown in cross section.

Figure 2 is an enlarged vertical section through the improved drain portion of the invention, the drain being of a non-automatic character.

Figure 3 is a detail horizontal section through the drain taken on the line 3-3 of Figure 2, and

Figure 4c is an enlarged vertical central 7 longitudinal section through the improved drain constructed to operate automatically.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the 7 several views, the letter A generally indicates the improved trap and drain and B a plumbing system with which it is incorporated.

As clearly shown in Figure 1 of the drawings, the plumbing system B includes a laundry drain or sink 5 located in a basement or the like below the main sewer pipe 6. As shown water is supplied to the laundry tub or sink 5 by means of supply pipes s5 7 one of which, preferably the cold water pipe has connected thereto a branch pipe '8 which leads to a part of the improved drain and trap A, as will be hereinafter more fully described. The outlet of the o0 laundry tray or sink 5 is connected to the trap and drain A by means of a pipe 9 which will be also hereinafter more fully described. 1

The improved trap and drain A shown 05 in Figures 1 to 30f the drawings is of the non-automatic nature and consequently a hand operated globe valve or the like 10 can be incorporated in the length of the pipe 8 for controlling the flow of water there- 10 through to the drain.

The drain and trap A comprises an outer casing 11 which can be of the airtight nature and to which has connected at the lower end thereof the drain pipe 9 from 5 the sink or laundry tray 5.

Disposed axially within the airtight casing 11 is the drain portion 12 per se of my invention. This drain portion 12 embodies a tubular outer shell 13 to which is threadedly or otherwise connected an outlet cap 14 at its upper end. This outlet cap 14 in turn supports an inner tubular sleeve 15 which comprises the portion through which the water or other sewage is adapted to flow. The upper end of the sleeve 15 has connected thereto the outlet sewer pipe 16 which extends to the main sewer pipe 6. It is to be understood at this point that my invention is particularly adapted for use in basements, cellars and the like where the main sewer pipe is located above acesspool, laundry tub or the like so as to insure the :efiiective carrying oil of the water ZfI'QIIl the basement to the main sewer and thus prevent theflooding of the basement.

Arranged within the sleeve 15 at a point intermediate its ends I provide a valve seat 17 having an axial way 18 therethrolgh. A ball valve 19 is adapted to normally fit upon the seat 17 and the provision 01 this seateand valve forms one of the most important features of my invention. The lower end of the tubular pipe or housing 13 is closed by a removable cap 20, when the device is of a non-auto=matic nature as shown in Figures 1 to 3 inclusive The lower end otthe sleeve 15 can have connected therewith in any preferred way a nozzle 21 which is arranged below the valve seat 17. plurality of ports 22 are formed in the tubular pipe or housing 13 and communicate with the inner sleeve 15 below the valve seat 17. These ports permit the flow of the sewage from the-casing 11 into the inner sleeve :15.

The water branch feed pipe 8 is connected with the'cap 14L andthe upper end of the tubular pipe orrhousing 13 as is clearly shown in Figure 2 of the drawings.

In operation of the improved drain and trap, when it is desired :to carry the water off from the casing 11, which has collected therein from the sink tub orwthe like 5, the valve 10 is open which permits the flow of water between the tubular pipe or housing 13 to the inner sleeve 15. This water will flow downto the lower end of the drain and then up through the nozzle 21 through the sleeve 15, up the pipe 16 and into the sewerage 6. This flow of water :will unseat the valve 19 and cause a suction inthe ports which will suck in the water from the easing'll andthus effectively raise the sain to the-main sewerage pipe 6. Iii-tor any reason the sewerage pipe -6 ispreventedtrom carrying oft the water and othersewage and-it thewater and sewage-fromthe main pipe 6 starts tovback up in the drain, the valve :19 will :be forced on its seat 17 which will .e-tl ec- :tively. preve nt the collecting of the sewage into the casing 11 dirom :t-he'niai-n sewerage sinking the same level with the floor of the cellar or basement and provide recesses in the upper wall of the casing.

In Figure 4 of the drawings I have shown the automatic arrangement for the drain and this drain is constructed identically with the drain shown in Figures 1 110.3 inclusive with the exception that :the lower cap is removed to the automatic device incorporated with the tubular housing 13 in lieu of-said cap.

As shown the automatic drain comprises an outer'tubular housing 25 to which is connected at its outer end a cap 26 for supportingthe inner sleeve 27 which leads ;to the sewerage pipe 6. The can 26 also receives the branch-water pipe 8 as in the drain previously described. At point above its lower end, the sleeve 27 is provided witha valve seat 28 on which is adapted-to seat -the ball valve 29. The lextreme'lower end ofthe sleeve 27 is provided with a combined nozzle and valve seat 30 onwhich is adapted to tit the sliding valve head 31, which is connected to an operating plunger 32. The plunger 32 is slidably mounted in a suitable packing gland 33 carried by the cap 341 which is threaded with the lower end of the :tubular housing 28. Suitable ports 35 are provided for permitting the :flow of the sewage from the casing 11 into the sleeve 27 betweenthe valve seats 28 and 30. As shown these ports 35 include short lengths of tubes which extend through-the tubular housing 25 and the sleeve 27.

A float 36 of annular .-cons,truction is slidably mounted on-the tubular housing 25 and is adapted to be raised and lowered by the water in the casing 11. The lower end of thefloat 36 has-rigidly connected-thereto at diametrically opposite points depending arms 37 which arein turn connected by a pin and slot connection 38 with lovers 39 which are pivoted as at 10 to depending supporting; brackets 41 carried by-the cap 34;. The iiiner ends otthe levers 39 are'piv otal-ly connected as at 412 to the plunger of the valve head 31 Now it is ohviousthat when the casing 11.

becomes filled with water that thefloat 36 will be raised which will move the valve bodv '31'below and oli' of the seat 30 which will permit the flow otthe water from the branch pipe 810 enter into the sleeve 27 and force the valve 29 from its seat, which will suck the water from-the casing 111 and as soon as the water or other sewage inethe easing ll falls below a predetermined level, the float 36 will fall and thus seat the valve body 31 and prevent the water flowing further through the valve seat 30 into the sleeve 27.

From the foregoing description, it can be seen that I have provided an exceptionally simple and durable means for insuring the efl'ective lifting of water from traps and the like to overhead sewerage pipes which will effectively prevent the backing up of the water into the trap from the sewerage pipes should the same become clogged up through any cause.

Changes in details may be made without departing from the spirit or the scope of this invention.
