Patented July 5, 1938 PATENT oFFlcE WASTE AND* OVERFLOW FITTING Gunnar B. Nystrom, Cleveland, Ohio, assignor d to The Republic Brass Company, Cleveland,

Ollio,' a corporation of Ohio Application November 1 claim.

This invention relates to a waste and overflow fitting and control therefor which is particularly adapted for use in connection with a bath tub but which is susceptible of use in other similar connections such as a lavatory or the like.

One of the objects of the invention is to provide a combined waste .and overflow fitting which includes a valve for controlling the discharge through the waste pipe and which is operable from the exterior of the Xture in such a manner that the valve is opened and closed with a minimum effort and with a snap action.

Another object of the invention is to provide a combined waste and overilow fixture and control therefor which is simple in construction, positive and convenient in operation and which is well adapted for production at comparatively low cost.

Another object of the invention is to provide a Waste .and overiiow fitting of the character described which is so constructed and arranged that the Waste valve may be removed through the overflow pipe and in which the mechanism for operating the valve is mounted on an escutcheon plate which is disposed over the end of the overflow pipe.

Further and more limited objects of the invention will appear as the description proceeds and by reference to the accompanying drawings in which Fig. 1 is a vertical sectional view showing my improved xture applied to a bath tub; Fig. 2 is a fragmentary sectional View showing the Valve operating mechanism in one position; Fig. 3 is a view similar to Fig. 2 with the parts shown in another position; Fig. 4 is a horizontal sectional view on the line 4 4 of Fig. 2 with the parts in an intermediate position; Fig. 5 is a detail View in end elevation disclosing one of the parts of the valve actuating mechanism; and Fig. 6 is a fragmentary detail view taken from the inner side of the escutcheon plate.

In Fig. 1 there is disclosed a portion of a bath tub I of usual construction placed against a wall 2. The bath tub has an overhanging portion 3 which engages the wall. Between the wall of the bath tub and the wall 2 extends the overflow pipe 4 which connects with a valve chamber 5. Leading from the valve chamber 5 is a waste pipe 6 which communicates with the bottom of the bath tub. Arranged within the valve chamber 5 is a valve 'I which seats on a valvey seat 8 and serves to control the discharge through the waste pipe. An actuating rod 9 which is preferably made up of a plurality of links is connected at its lower end with the Valve 'I as shown at Ill and extends upwardly through the overflow pipe 4 and threadedly secured to the upper end thereof is an adjustable connection II. The bath tub is provided with the usual overflow opening I2 and the upper end of the overflow pipe is connected in covering relation to said opening in any suitable manner.

Disposed over the opening in the bath tub is an escutcheon plate I3 which is held in place by means of screws I5 and I6 which engage in threaded openings provided in the iianges II and I8 on the overflow pipe 4. A gasket I9 is disposed between the overflow pipe and the outer Wall of the bath tub. The escutcheon plate I3 is provided with a centrally disposed somewhat elongated opening 20 which ares outwardly on the inner side thereof. Pivotally mounted in the opening 20 is a valve actuating lever 2I the inner end of which is connected With the member II on the upper end oi' the valve actuating rod 9. The outer end of the valve actuating lever 2| is somewhat T-shaped so as to provide a handle for actuating the same. The lever 2I is also provided with a somewhat spherical portion 22 which engages in the opening 20. The inner surface of the escutcheon plate immediately adjacent the opening 20 is provided with a boss 23 which has therein a pair of grooves 24 and 25 which are disposed on opposite sides of the opening, the purpose of which will hereinafter appear.

Slidably and loosely mounted on the lever 2| is a member 26 which is spring pressed outwardly by means of a coil Spring 21 which is held in place by means of a washer 28 and a pin 29. The member 26 has thereon a pair of spaced fingers 30 and 3| the outer faces of which are tapered to provide knife edges which engage in the grooves 24 and 25, respectively. The spring 2l urges the member 26 intol engagement with the grooves provided on the inner face of the boss 23. The inner face of the opening 20 in the escutcheon plate is elongated and ared outwardly slightly .and these faces serve to limit the movement of the Valve operating lever in two directions.

With the parts in the position shown in Fig. 2, the valve is in the elevated or open position to permit Water to be discharged from the bath tub through the waste pipe. The spring pressed member 26 serves to hold the valve in the open position. When the parts are moved to the position shown in Fig. 3, the valve is in the closed position and the spring pressed member 26 serves to hold the lever in the position shown. When the valve is moved from the open to the closed position by means of the valve operating lever, the spring produces a snap action and serves to hold the lever in either of the two'extreme positions, the edges of the opening in the escutcheon plate serving to limit the movement of the lever in two directions.

Should it be desired to remove the valve for the purpose of replacement or repair, it is only necessary to remove the escutcheon plate and pull the valve and valve actuating mechanism out through the overilow pipe.

It will now be clear that I have provided a combined Waste and overflow tting and valve actuating mechanism thereforrwhich will accomplish the objects of the invention as hereinbefore stated. It is to be understood that various changes may be made 4in the details of construction and arrangement of parts Without departing from the spirit of my invention and that the embodiment of the invention herein disclosed is l to beconsidered merely as illustrative and not in a limiting sense as the invention is limited only in accordance. with the scope of the appended claim.

Having thus described my invention, what I claim isz.

A combined waste and overflow fitting including a Waste pipe and an overiiow pipe, a valve for controlling the discharge through said Waste pipe, a valve actuating link connected with said valve and extending upwardly through said overflowV pipe, a plate disposed over the upper end of said overow pipe, a Valve operating lever pivotally mounted in said plate and opera-ble from the exterior thereof and connected with said link, a member slidably mounted on said lever and having a knife edge, the inner face of said plate having a groove therein receiving said knife edge, and a sp1-ing urging said member outwardly and serving to hold'said lever in either of two positions.
