i; a I. 4! TTORNEK Filed Feb. 3. 1950 Patented June 23, 1931 UNITED STATES PATENT OFFICE FRANK G. BROTZ, OF KOHLER, WISCONSIN, ASSIGNOR' T KOHLER COMPANY, OF KOHLER, WISCONEiYIN, A CORPORATION OF WISCONSIN LAVATOR-Y HAND LIFT DRAIN Application filed February 3, 1930. Serial No. 425,471.

This invention has for its object to provide a lift drain for lavatories and the like requiring only the lifting and turning to one side of the drain plug in order to open the drain and permit the contents to flow out, the return of the drain plug to its seat again closing the drain outlet.

Another object of the invention is to provide such a drain plug with a removable valve member bearing the handle by means of which the plug is turned for locking and unlocking it and for engaging and disengaging the screw threads by meansof which the valve member is secured to the guide tube.

lVit-h the above and other objects in view the invention consists in the lavatory hand lift drain as herein claimed and all equivalents.

Referring to the accompanying drawings, in which like characters of reference indicate the same parts in different views,

Fig. 1 is a sectional elevation of a lavatory hand lift drain constructed in accordance with this invention;

Fig. 2 is a similar view with the drain plug held in its open position;

Fig. 3 is a similar view wth the plug member removed, and

Fig. l is a sectional view on the plane of 33 line 44 of Fig. 1. I

In these drawings, 10 indicates a lavatory or like container having an overflow passage 11 and provided with a drain spud or drain connection 12with' its funnel-shaped flanged upper end sealed into the outlet opening and clamped in place by a nut member 13 threaded thereon with a gasket 14: of rubber or other suitable material clamped between it and the bottom of the container. 7

Loosely contained within the drain connection 12 is a guide tube 15 having threaded within its upper end the lower portion of a plug member 16 bearing a handle or knob 17, by means of which it may be turned or raised andlowered. The plug member 16 has a conical valve surface resembling a poppet valve which closely fits a corresponding- 1y shaped valve seat 18 in the upper end of the drain connection 12 so that when the 55 valve is in its lower position, as in Fig. 1, it

19 in tube 15 registering with the overflow rope'nings 20 in the drain connection 12. One of said openings 19 is of an inverted T shape and has projecting into it a stop pin 21 which may be riveted or otherwise fastened to the drain connection. Such stop pin prevents the 11;

removal of the tube 15 and, by engaging with the shoulders formed on either side of the contracted portion of the inverted T-shaped opening 19, it supports the waste plug in its elevated or open position, as shown in Fig. 2,

thus permitting the drain of the container through the openings 19, which are then exposed.

While the plug member 16 can be unscrewed from the guide tube 15, it normally 7 remains connected therewith and is-only disconnected to permit of access to the interior to permit the cleaning of the pipes and trap through the drain opening. The tube is not removable and consequently there is not the 7 likelihood of the plug being misplaced or stolen from hotels or other public places.

Instead of exposing the lower threaded end of the drain connection as usual and expanded tailpiece 22 is employed, which is threaded into a skirt portion'23 of the nut member 13 and makes a neat connection therewith concealing all screw threads.

What .I claim as new and desire to secure by Letters Patent is:

A lift drain for lavatories or the like comprising a drain connection, a plug member seated therein and provided with a handle by means of which it may be turned or lifted, a guide tube in which the plug member is re movably threaded, said guide tube fitting loosely in the drain connection and having a pin and slot connection therewith for limiting the movements of the plug member.

In testimony whereof, I aflix my signature.

FRANK Gr. BROTZ.
