10 Claims.

This invention relates to equipment for lavatories, bathtubs, and the like, and more particularly to a waste outlet fitting embodying both a waste stopper construction and trap means for hair, lint, gems or other small articles that might pass the stopper, and clog the waste system.

A principal object of the invention is to provide a device of this character that will prevent clogging in a Waste system.

Still another object of the invention is to provide a waste outlet fitting having a receptacle or trap from which articles .accidentally dropped into the bowl or tub may be recovered readily.

A further object of the invention is to provide a simple fitting whose parts may be readily removed as a unit fromthe waste outlet for cleansing purposes, thus providing a sanitary construction.

Another object is to provide means whereby the parts may be removed as a unit from a body only in determined positions of the parts relative to said body so that they may be removed for cleaning or emptying of the receptacle or trap, but in normal use will not be removable from the body.

To the accomplishment of the foregoing and such other objects as, may hereinafter appear, this invention consists in the novel construction and arrangement of parts hereinafter to be described and then sought to be defined in the appended claims, reference being had to the accompanying drawings forming a part hereof which shows, merely for the purpose of illustrative disclosure, preferred embodiments of the invention, it being expressly understood, however, that changes may be made in practice within the scope of the appended claims Without digressing from the inventive idea.

Referring to the drawings, and first to Figs. 1-5, inclusive, l0 denotes a tubular body adapted to be inserted inthe drain opening of a lavatory, Washbowl, tub, or the like. This body has an annular flange II which is adapted to seat around the mouth of the drain opening. It is provided, also, with an externally threaded portion 12. A clamping member, or look nut, l3, threadedly engages the threaded portion I2 and serves to fasten the body In securely in the drain opening. Suitable sealing means, such as the ring 14, of rubber or other available packing material, is provided. A washer l5 of metal, or the like, lies between the ring l4 and the lock nut l3.

The body I0 is provided with a second threaded portion [6 for attachment thereof to a waste pipe or the like (not shown). An internally extending shoulder is provided for the body. This shoulder, in the embodiment shown, consists of an annular rib l'l formed on said body. Suitable overfiow drain openings ID are also provided in the body member.

The body [0 serves to receive the waste plug, valve or stopper member, I8. This member [8 is hollow and is admeasured externally to seat in its closed position upon a seat [9 provided on the body member ID. The stopper I8 has an in- It also has an opening 2| in its top 22.

A lift member, or lever, 23 is provided for raising and lowering the stopper. This lever 23 has a ball portion 24 and a pair of arms 25, 25a. The ball portion 24 is rotatably supported within the stopper I8 and the manipulating arm 25 extends outwardly of the opening 24. Suitable packing 26 is provided around the ball 24 to prevent leakage. This packing is suitably pressed into sealing engagement with the stopper and the ball 24 by a Washer member 21. The latter is pressed into place by a threaded ring portion 29aof a hollow guide member 29, the portion 29;; being screwed into the threaded portion 2!] of the stopper.

The guide member has a number ofspaced prongs or feet 30 depending from thering iportion 29a. Transverse, parallelly-extending ribs 3| are provided between adjacent pairs-of the prongs or feet 30 just below the ring portion 29a.

These ribs are reentrant at 3Ia appearing .as chords of the ring member portion 29a in Fig. 5. The spacing between the ribs 30 is less than the diameter of the ball 24 and their upper inner edges 39b serve as abutments to retain the ball 24 within the stopper when the guide member 29 is assembled with the stopper. The arm 25a of the lever 23 extends into the space between the ribs 3m and is so admeasured in width that it prevents rotation of the ball member on a vertical axis but permits its rotation on a horizontal axis. The lower ends of the feet 30 are suitably joined by a guide ring 32. The described elements of guide member 29 are preferably a one-piece construction but may be individual parts suitably united to form the said guide mem: ber. The ring member 32 has an overall diameter admeasured to permit free but guiding move= ment of the guide member 29 within the body I so that guide member 29 as a unit guides the movement of the stopper I8.

A waste receptacle, or trap, 35 that acts as a strainer, is provided. This receptacle may be of any suitable construction. In Figs. 1-5, inclu sive, it has cup-like form and is admeasured to lie within the body I0 with sufiicient clearance between its outer surface and the inner wall of thebo'dy Ii] toperniit free drainage through its perforations 35 The strainer 3-5 is adapted to be supported from the shoulder H. To this end, it has an annular flange 37 that restsupon the shoulder IT. This flange is provided witha suit able slot 38. A bayonet pin, 'or lug, 39 is provided on' the wall of the body Iii adjacent the shoulder I'I'so that seating of the flange 31 on shoulder I'irequires the slot 38 and stud 39 to be in alignment so that the flange can pass'the pin 39. When the slot and pin are out of alignment the receptacle cannot be withdra'wzifrom the body III, as will be described more in detail hereinafter. The receptacle, or strainer, 35 is provided in its bottom with a threa'ded'opening 40 that lies substantially in the axisof' saidreceptael'e. A rod, or "stud, II having a threaded reduce-d peruse 32 is tllieadedly supported in theopening 46' and. extends substantially axially of the strainer to a point above the Ieve ci the sense at. The rod 4| is suitab i'i couples to a portion 25b 'of' the arm 25a of the ball lever 23 by a link 55. This link is pivoted at '46 to the rod 4| and at 41 to a portion 25b of the arm 25a. Thus, the waste receptacle 35 is in efiectremovably coupled'to the lever 23.

The arm 25a has a nose 25c that is adapted to limit rotation of the ball 24 in one direction by abutment with the ring portion 2% or the guide member 29. "The link 46. and the rod, or stud, 41 are so adine'a'surcd in length that, when the aforesaid abutment occurs, the pivot points 63, 4 are farthest apart in the axial direction of body Iii, as shown in Fig. 2', and the stopper I8 is then lifted away irbin its seat is. This represents the open position of the waste plug or stopper IS. The "stopper or waste plug member is closed by grasping the manipulating arm 25 of the ball lever 23 and rotating the latter to move said arm 25 to the position shown in Fig. 1. This, through the action of link 45, causes the pivot point 41 tomove axially toward pivot point 4.6 and causes the stopper to be moved into closed relationship on the seat I9 of the body I0. Dur i'ng movement of the stopper onto or ofi its seat, I rsu mem er. 23 rves to maint n th stopper I8 in substantial alignment with said seat I9.

To clean or empty the basket or strainer 35, the manipulating arm 25 is grasped and rotated until slot 38 and pin 39 are in alignment. The assembled stopper I8 and waste receptacle 35 can then be removed as a unit from the body II]. The receptacle 35 is then unscrewed from the stud 4|, emptied, and replaced thereon. The

reassembled parts are put back into body It and rotated until the slot 33 and pin 39 are realigned. This permits the flange 31 to pass said pin 39 and reseat itself on shoulder I1. When this occurs, a further slight rotation of the stopper I8 mis'aligns the slot and pin and places the device in condition for use. In this condition the stopper and receptacle cannot be withdrawn from body Iii. Thus, during use, the stopper and receptacle assembly will not be lifted out of body It when the arm 25 is grasped. In other words, means are provided by the slot-and-pin arrangement to retain the parts in position of use.

A modified form of construction is shown in Figs. 6-8, inclusive.

Referring to these figures, I05 denotes a tubular body substantially similar to the body I 0. This body IBEI. has an annular flange III which is adapted to seat around the mouth of the drain opening. It is also provided with an externallythreaded portion II2. A clamping member, or lock nut, I I3 threaded engages the threaded portion H2 and serves to fasten the body I00 securely in the said opening. Suitable sealin means, such as the ring H 3, of rubber or other available packing material, is provided. A washer H5 of metal, or the like, lies between the ring H4 and the'lock nut I I3.

The body is provided with a second threaded portion I I6 for attachment to a waste pipe or the like (not shown).

An internally-extending shoulder i provided for the body. This shoulder, in the embodiment "shown, consists of a bead or ribs II'I formed on said body. Suitable overflow drain openings III) are provided in the body member.

I The body I serves to receive the waste plug or stopper member II8. This stopper is hollow and is admeasured externally to seat in its closed position upon a s'eat I-I 9 provided on the body member I00? The stopper has an internallythreaded portion I20. It also has an opening -I2I in its top 122'. A lift member I23 is provided for raising. and lowering the stopper. This member has a ball portion I24 and a pair of arms I25, 125a. The ball portion I24 is rotatably supported within the'stopper I I8 and the manipulating arm I25 extends outwardly 'of the opening I24. Packing I26 is provided around the ball I24. The ball I24, in turn, is suitably held within the stopper by a. retainer member I2 l. The'latter is held in place by a hollow guide member I29 which has a threaded. portion I29d screwed into the threaded portion I20 of the stopper;

The guide member has a number of spaced prongs, or feet, I30. The member I29, too, is provided with ribs I3I on its ext'ernalfsurface. In the embodimentshown, these ribs extend 'in-alignment with the feet.

A waste receptacle, or trap, I35 that acts as a strainer, too, is provided. This receptacle may be of any suitable construction. In the embodiment shown, it has cup-like form and is ad- ,measured to lie within the body I00 with suificient clearance between its outer surface-and.

the inner wall of thebody I 96 to permit free drainage through its perforations I 36, The strainer I35 is adapted to be supported from the shoulder III. To this end, it has an annular flange I31 that rests upon theshoulder III. This flange, likewise, may be provided with a slot I33 for the same purpose as slot 38. A bayonet pin, or lug, I34, similar to, and for the same purposes as, pin or lug 39, may be provided on the body I113.

The bottom of the receptacle has a reentrant groove I33 and a slot I39 arranged at substantially right angles with it. It also has an opening I43 that is substantially centrally located relative to the groove and the slot. A rod or stud I4I, which has a reduced portion I42 that fits slidably in the opening I43, is provided. A spring I43 surrounds the reduced portion I42 and'serves always to urge the rod away from the bottom of the strainer I35. A suitable limiting pin member I44 is positioned in the reduced portion I42 of the stud MI and extends substantially transversely of the axis of the said stud I4I. This pin is admeasiired in length and diameter as to lie within the groove I38 in the assembled relationship of the parts and also to be capable of passing freely through the slot I39 when it is desired to remove the strainer I35 from the rod or stud I4I. Such removal is eifected by depressing the rod I4I so that the pin member I44 clears the groove I38 and by then rotating the strainer I35 to bring the pin member I44 into alignment with it. Thepin member then can easily pass through the slot I39 and the strainer or basket I35 can then be removed from the rod I4I.

The rod MI is suitably coupled to the arm Ia of the ball lever I23 by a link I45. This link is pivoted at I46 to the rod MI and at I41 to the arm i25a. Thus, the waste receptacle is in efiect removably coupled to the lever I23, and thereby the stopper H8 and receptacle I are removable as a unit from the body I03.

The link I45 and the rod I4! are so admeasured that, when the pivot points I46, I41 are in axial alignment, as shown in Fig. 2, the stopper H8 is lifted from its seat H3. This represents the open position of the waste plug or stopper H8. The stopper or waste plug member is closed by grasping the manipulating arm I25 of the ball lever I23 and rotating the latter to move said arm I25 to the position shown in Fig. 1. This, through the action of link I45, causes the stopper to be moved into closed relationship on the seat II9 of the body I30. During movement of the stopper onto or oil its seat H3, the guide member I33 and its ribs I3I serve to maintain the stopper H3 in substantial alignment with said seat II9.

To clean or empty the basket or strainer I35, the manipulating arm I25 is grasped and rotated until the slot I33 and pin or lug I34 are aligned. The assembled stopper I I8 and waste receptacles I35 can then be removed as a unit from the body I53. The stud MI is then pressed down against the resistance of spring I43 so that the pin I44 clears the groove I38. The perforated receptacle I35 is then given a turn sufiicient to align the slot I33 and pin member I44. This will permit separation of the receptacle I35 and the stud I4I by the removal of the receptacle from the stud or vice versa. The separated receptacle now can be emptied and cleaned.

After cleansing, the receptacle is reassembled with the plunger MI and the assembled unit is reinserted in the body I00.

With the devices described, simple, efiicient constructions are provided with few working parts. Waste material is caught by the baskets or strainers 35 or I35 and retained therein for removal rather than passing to the drain pipe and causing clogging Another advantage is that valuable articles, such as gems or the like, can be recovered from the strainers or baskets 35 or I35 as they will be retained by either. Moreover, another advantage of the invention is that the traps or receptacles 35 or I35 and their respective plugs I8 or H3 are removable as a unit from the device only in determined positions of the receptacles relative to the bodies I3 or I00, namely, when slots 38 or I33 register with lugs 39 or I34. In normal use of the device, as stoppers and traps in drain bodies III or I00, removal as units is prevented by the pins or lugs 39 or I34.

While specific embodiments of the invention have been disclosed, it must be understood that variation in structural detail within the scope of the appended claims is contemplated. There is no intention of limitation to the exact details of constructions shown and described.
