DRAIN FIXTURE.

Application led February 16, 1925. Serial Nb. 9,576.

concealment of 'the drain valve operating mechanism and yet render the operating parts readily accessible for cleaning and repair. This difficulty is particularly -pronounced in the case of built-in bath tubs in which the .drain and overflow pipes are wholly enclosed by the wall of the tub.

One object of the present invention is the provisionof a drain fixture lin which the drain valve is readily accessible and operated by concealed mechanism.

Another object is to simplify and otherwise improve the construction and operation of devices of this character.

Other objects and advantages will appear from the following description of an illustrative embodiment of the present invention.

The single figure of the drawing is a sectional view of a combined drain and overiow xture constructed in accordance with the present invention.

The fixture selected for illustration comprises an overflow pipe 10 and drain pipe 11 both communicating with a discharge or soil pipe 12 through the usual T-itting 13. An elbow 14 is fixed tothe upper end of the pipe 10 and adapted to register with the usual overiow opening 15 formed through the end wall 16 of the tub. This elbow is flanged, as

' How from the tub t'o and through the elbow 14 and pipe 10. The wall of the tub is clamped between the elbow 14 and escutcheon by any appropriate means, such as a pair of which extend through the escutcheon and are threaded into appropriate lugs 21 car-- ried by the elbow.

An elbow 22 ixed to the end of pipe 11 is adapted to register with the usual drain opening 23 formed through the bottom 24 of the tub. The open end of this elbow is flanged, as at 25, or otherwise fashioned, to l,

screws, one of which is shown at 20,y

land passage 29 in the valve seat 27 the inner face of the bottom of the, tub, so

that the bottom wall of the tub may be securely clamped between the valveseat 27 and elbow 22.

The port or passage 29 through the valve seat is controlled by a valve 30 in the form of a disk having a depending peripheral ange 31 adapted to project into a corresponding groove 32 formed in the exposed face of the valve seatand surrounding the passage 29. j The valve carries a rigid stem 33 depending through the passage 29 into the elbow 22. A valve operating chain 34 is connected tothe free'end of the stem 33,

andextends through drain pipe 11, fitting 13 and overflow` pipe to an appropriate control mechanism preferably mounted.in the escutcheon 18. In this instance, the control mechanism comprisesl a hollow rod or tube 35 closely fitted forlengthwise movementin an appropriate boss 36 formed as an integral part of the escutcheon. An appropriate packing land 37 surrounding the rod 35 offers su lengthwise movement of the rod` as to yieldably retain it in any position of adjustment.l 4The rod 35 projects through the overiiow opening 15 in the tub with the inner open end thereof in position to receive the chain 34. At its outer end the rod carries a hollow knob 38 constituting a suitablevoperating handle.

In assembling the valve and control mechanism the chain 34 is ordinarily threaded through the passage 29, pipes 11 cient frictional resistance to and 10, overflow opening 15, and tube 35,

and the valve 30 isplaced in the full line position shown before the escutcheon is.

placed over the overow opening. The escutcheon is then mounted in position and the tube 35 adjusted to the full line position shown. The chain 34 is then drawn upwardly through the rod 35 until all excess valve control mechanismv to fixtures .of

various sizes.

With the tube kor rod 35 in the full line position shown, the chain 34 is slack andthe valve 30 rests by gravity upon the upstanding rim `39 formed between the gro'over2 slack is taken up, and fixed in such position lfm drain passage 29 is thus effectively closed. To open this passage it is only necessary to pull the rod A upwardly into the dotted line position shown. This movement of the rod is transmitted through chain 34 to the end ofthe valve stem 33, causing the valve 53() to tilt upwardly away from the rim 39 into the dotted line position. Vater from the tub is thus permitted to escape beneath the valve and through the passage 29 and drain pipe ll. It will be noted that in all positions of' the valve, a portion at least of the flange 3l remains in engagement with the groove 32. thus providing an appropriate fulcrum during this tilting or rocking action of the valve. The flange 31 and groove 2&2 also serve to guide the valve into proper closing position when the slack in the chain 34 is again released by shifting the rod 35 into the full line position shown.

l have discovered that the use of a tilting valve above the drain opening of the tub results in an increased flow therethrough. This increased fiow is attributed to the fact that the upwardly inclined open position-of the valve tends to destroy the vortex effect which ordinarily occurs in draining a tub or basin.

Variouschan-ges may be made in the embodiment of the invention hereinabove' specifically described, without departing from or sacrificing any of the advantages of the invention as defined in the appended claims.

I claim:

1. ln a drain fixture the combination of an overflon7 passage, a drain passage in open communication therewith, a valve normally covering said drain passage, an element depending from beneath said valve into said drain passage. and a flexible tension transmitting means in said overflow passage connected with said element for pulling the same laterally to thereby lift said valve.

2. ln a drain fixture the combination of an overflow pipe, a drain passage, a valve cooperating therewith and movable axially thereof, a centrally disposed member dcpending from said valve and extending within' said passage, and tension transmitting means associated with said member and operable to tilt said valve.

2l. lua drain fixture the combination of al valve seat having a drain passage therethrough, a valve `resting on said seat. to close said passage and so arranged as to be movable axially thereof, said valve having a downwardly projecting stem, and flexible tension transmitting means secured to said stem and operable to tilt said valve to eflect adjustment thereof.

- 4. ln a drain fixture the combination of a valve seat havingl a drain passage therethrough and a groove encircling said passage, a disk valve resting on said seat to close said passage and having a flange engaged in said groove, a member depending from said valve and means pulling laterally on said member for tilting said valve to open said passage.

5. ln a drain fixture the combination-of a valve seat having a drain passage therethrough` a valve resting on said sea-t to close said passage, interengaging means between said valve and seat to restrain said valve against lateral .movement on said seat, a

member depending from said valve Vandy means pulling laterally on said member .for

` tilting said valve to op'en said passage.
