11 Claims.

This invention relates to waste and overflow fittings such as are particularly adapted for use on bath tubs and the like. It is customary in making fittings of this type to employ a T mem- 1 her to which the overflow, waste and outlet pipes are connected. In this construction the overflow and outlet pipes are connected to oppositely disposed portions of the T member and are consequently maintained in vertical alignment. Because of the variations in the slope or inclination of the side walls-of different fittings, the'waste pipe connecting the waste outlet of the tub and the T member varies in length. This requires the use of a specially formed waste pipe connection, depending on the slope of the particular tub, and entails considerable difficulty in making the fitting.

The primary object of my invention, therefore, is the provision of a combined fitting whereby 20. the use of a T member is obviated and to which the various connections are adapted to be made regardless of the'slope of the sides of the tub.

In carrying out the invention I prefer to combine the waste pipe L, overflow L connection and. discharge outlet connection into a single integral unit as will be hereinafter more particularly described.

A further object is to provide a fitting which is directly associated with the waste outlet and which may be utilized regardless of the pitch of the tub.

Another object is to provide a fitting which permits flexibility in assembling the various parts which are adapted to be connected thereon.

A further object is to provide an overflow L fitting or attachment which is adjustable and which is maintained against the side walls of the tub at any desired angle. The overflow pipe extending therefrom is readily connected to the combined fitting regardless of the pitch or slope of the tub.

Another object is the provision of a waste plug strainer in which the water outlet therethrough is considerably enlarged thereby permitting a more speedy emptying of the waste matter in the tub.

Another object is to provide a fitting of this type with one or more adjustable connections of novel construction which are associated with the said combined unit as will be hereinafter more particularly described.

My invention further includes other objects, advantages and novel features of design, construction and arrangement hereinafter more particularly referred to and which will be apparent from the accompanying drawings.

Referring to the drawings, and particularly to Figures 1 and 2, the apparatus made in accordance with my invention includes a combined fitting for the discharge of waste fluid either directly from the waste outlet of the tub or indirectly from the overflow connection associated therewith. This combined fitting is indicated at 20 and integrally includes a waste L connection 21 directly associated with the waste outlet of the tub, an overflow L connection 22 and a dis charge outlet 23. 7

While the invention as hereinafter described will be made to relate to plumbing for the release of waste water, it will be understood that the flow of other liquids may also be controlled by the use of a fitting made in accordance therewith.

The bath tub, or similar fixture, with which the invention is associated comprises a sloping side wall and a bottom wall as indicated at 24 and 25 respectively. The bottom wall 25 of the tub has the usual waste opening indicated at 26 in which a waste plug member 27 illustrated in Figs. 4 and 5 is located. The upper portion of the member 27 is flanged as indicated at 28 to maintain the same in a fixed position in the opening 26 substantially coincident with the bottom portion of the tub. The lower portion of the member 27 is threaded as indicated at 29 to engage a tapped opening 30 in the waste L portion of the fitting 20. A suitable washer 31 is interposed between the under surface of the tub and the waste L connection 21 of the fitting to insure a water tight joint between these respective members.

Cross bars 32 and 33 are integrally associated with the lower portion of the member 2'? to form a strainer therefor. The cross bars are arranged substantially at right angles to one another and extend from the member 27 in the form of a basket. This construction increases the area available for the discharge of the waste water and consequently facilitates a speedier emptying of the contents of the tub.

A circular rib 34 extends from the body portion of the fitting 20 and is internally threaded as indicated at 35 to receive an externally threaded fastening member or nut 36. The portion of the casing 20 defining the discharge opening 23 is curved in a downwardly direction as indicated at 37, the lower surface of the same presenting a circular concave surface or seat 38 against which the curved upper portion of a discharge pipe 39 is adapted to position. A gland ring member is indicated at 46, the purpose of which will be hereinafter more particularly described.

In making this connection the upper portion of the discharge pipe 39 is manually worked into a flange, the pipe being of lead or similar ductile material to approximate the concave surface 38 of the member 20. On the tightening of the nut 36 the upper surface of the gland ring presses against the under surface of the pipe flange and forces the same to position against the concave surface 38 as clearly indicated at 41. Due to the flexible characteristics of the lead pipe, a firm fitting of the same in the member 20 is assured in this manner even in the event that the cooperating members are not perfectly aligned.

The overflow L of the combined fitting 26 is inclined at an angle slightly more than 90 with the center line of the fitting 20. This permits a greater degree of flexibility in joining the overfiow pipe 42 to the L portion 22 as will be hereinafter more particularly described. The upper portion of this fitting is screw threaded as indicated at 43 to receive an internally tapped nut 44. The interior walls are bevelled as indicated at 45 to seat a washer 46 between its surface and the exterior of the overflow pipe 42. The Washer is preferably of lead or similar ductile material so that the inner surface of the tapped nut 44 will force the washer to a tight fit against the bevelled surface of the fitting 20'when the nut is tightened.

In this construction the end of the overflow pipe 42 extending into the fitting 20 is not rigidly maintained in alignment with the overflow L. portion of the fitting. Regardless of the angle, which the pipe 42 may assume in the fitting 26, a tight connection is assured through the washer 46. A greater degree of flexibility is therefore obtained between these respective parts by having the overflow L connection of the fitting 20 pitched'substantially at a corresponding angle to the average slope or inclination of the side walls of a tub.

An overflow elbow connection 47 is threaded as indicated at 48 to maintain the tapped end of the overflow pipe 42 therein adjacent the tub. The elbow connection 4'? comprises a bell shaped flange 49, the surface of which is adapted to engage a washer or gasket 50. In the interior of the elbow 47 are oppositely disposed recessed lugs, one of which is indicated at 51, the inner surfaces of the same being adapted to coact with the curved end surfaces of a cross bar 52, clearly illustrated in Figure 1. A flanged ferrule 53 is adapted to extend through the overflow outlet opening in the tub wall to maintain the washer 5O thereon. Bosses 54 and 54 extend from the ferrule and contain screw openings therein through which the screws 55 and 56 are placed to engage tapped openings 5'? and 58 in the cross bar 52 illustrated in Figures 3, 6 and '7. When the retaining screws 55 and 56 are drawn tight the elbow 47 is firmly pressed against the washer 50 and connected to the tub wall, regardless of its pitch, the curved surface of the cross bar 52 adapting itself to position against the lugs to accommodate variations in the slope of the tub walls. The overflow opening is covered by the usual plate or escutcheon 59 secured in position by a center screw 60 in the tapped opening 61 of the cross bar 52. The customary chain and stopper associated with the tub fixture are indi cated at 62 and 63 respectively.

Referring to Figures 8 and 9, modified forms of the cross bar and overflow plate are illustrated. The plate or guide for the overflow opening is constructed to include a circular recessed groove 64 adapted to coact with the outer surface of the ferrule 53. The cross bar has a single centrally tapped opening 65 for the reception of the screw 60. In this construction the elbow is secured to the tub by the use of a single central screw from the plate to the cross bar, the ferrule being maintained in position against the plate and the washer against the bell shaped flange of the elbow. The cross bar adjusts itself within the oppositely disposed lugs in the elbow so that these respective members are fastened together withoutexerting any bending action on the screw. The connection of the various members associated with the elbow is easily facilitated regardless of the pitch or slope of the tub.

Referring to Figure 10 a modification of the combined fitting is illustrated in relation to the waste outlet of the tub. The combined fitting unit is indicated at 66 and is directly associated with the waste plug member 67 substantiallyas hereinbefore described. The overflow L connection integral therewith is indicated at 68 into which an overflow pipe 69 extends and is adjustably maintained by a nut '70 and washer 71. A discharge connection of the fitting is indicated at 72 which in this instance is located in alignment with the overflow L connection, it being particularly desired to emphasize that the position of the discharge outlet may be located at any desired point in the combined fitting without departing from the nature and spirit of the inven- 1' tion. A discharge pipe is indicated at 73 and is adjustably secured to the connection 72 by means of a nut 74 and washer '15.

Referring to Figures 11 and 12, the fitting is illustrated having a discharge connection located 1 at one side of the same as indicated at 76. Waste outlet and overflow L connections are indicated at 7'7 and 78 respectively.

The discharge connection 76 is internally threaded as indicated at 79 to receive a tapped spud insert having a circular concave face 81 extending outwardly therefrom, the upper portion'being. substantially flush with the end of the discharge connection 76. This connection is also exteriorly threaded as'indicated at 82 to receive an internally tapped fastening member or nut 83. A gland ring is indicated at 84. In a manner substantially similar. to that hereinbefore described, the upper portion of a discharge pipe 85,-which is of ductile or soft material such as lead, is manually worked into a flange approximating the concave surface of the spud insert 80. When the fastening member 83 is tightened on the outlet connection 76, the gland ring presses against the under surface of the flanged pipe 85 and forces the same to position against the concave surface 81 of the spud insert. The pliable character of the lead pipe insures that a tight fit be made around the entire periphery of the spud insert even in the event that the outlet connection 76 and discharge pipe 85 are not in perfect alignment.

The inventive concepts herein disclosed may be employed in other desired forms. Therefore, various modifications of the present improvements may occur to those skilled in the art and may be made without departing from the scope and purview of the invention.
