ATTACHMENT FOR FLUSH TANKSv Application tiled March 30, 1925. Serial No. 19,485.V

To all who/ml #may concen:

Bc it known that I, BERT O. TILDEN, a citizen fof the United"States, residing at Trenton, in thecounty of Mercer and State of New Jersey, have invented certain new and useful Improvements in Attachments for Flush Tanks, of which the following is a specification.

This invention relates to improvements' in `{iush valve operating mechanisms, designed particularly for use in connection with vitrified 'china flush tanks, and has for its object to provide a fitting of the class, wherein all of the exposed part-s are made of durable and ornamental vitritied material` which effectually conceal all of the metal connecting` and supporting parts that usually extend beyond the tank. A particular obiect of the present invention is to provide a novel. and simple china head-piece, which is supported byand conceals a portion of the valve-operating stem, and at the same time affords a novel support for the vitriticd operating handle. `A further object is to provide a. head-piece, which is operated upon in the molding stagi-if of its manufacture, for facilitating the connecting and securing of the related parts Without requiring any machining or yother Work. And a further object is to provide a china head-piece, which is so constructed and applied to'the metal parts of the fitting that, should the head-piece become broken or de'- stroycd the metal operating parts may still perform their regular functions.

I attain these objects by the means set forth in the detailed description which follows, and as illustrated by the accompanying` drawing, in which- Figure 1 is a broken front side elevation of a flush tank to which my improvement is applied. Fig. 2 is a broken end elevation of the tank. Fig. 3 is a horizontal section taken centrally through the operating arts shown in Figs, 1 and 2. Fig. 4 is a ront end view of the china head.v Fig. 5 is a rear end view of the same. Fig. 6 is an enlarged central section taken on line 6 of Fig. 7. And Fig. 7 is an enlarged elevational view taken in the direction of the arrow in Fig. 6.

In the accompanying drawing, 2 represents a china ush tank of the usual construction, which preferably has its front face curved, as at 2 for strengthening and ornamenting the tank. The flushing Water may be supplied tothe tank by `any of the usual means (not shown). The filling of the tank may be controlled in the usual manner by a float 3, shown conventionally in Fie. 2. The emptying of the tankmay be effected by any of the well-known flushing valve i'nechanisrns` which it is not deemed necessary in the present case to show. The flush valve however, may be operated by means of a lift rod 4t', which may' be moved vertically by means of a lever Il, one end of which is preferably formed U-shaped for facilitating mounting the lever between perforated ears 5', of a bracket 5 which mounted on the inner wall 21 of the tank, as best seen in Figs. 2 and. 'lhe bracket 5 is 'formed with a. tubular huh 5, which is shown inserted part-way into a molded opening 2h, of the front wall oi' the tank, and forms together with a. fiange bushing` G which is inserted from the outside of the tank, a bearing that supports n relatively long externally threaded sleeve 7, to which the bushing 6 is threaded. A nut S is applied to the projecting inner end of the sleeve 7, for rigidly clamping and holding the parts in place, as shown in Fig. The lever It is rocked, for opening and closing the flush valve, by means of a relatively large loop 9, which is mounted on or may form a part of the inner end of a stem 9, the latter preferably passing through and being freely rotatable in the sleeve 7.

Outside of the tank` and beyond the bushing 6, is mounted a china escutcheon, 10, the latter having a central opening to receive the sleeve 7. The bottom face of the escutcheon is preferably concave, as at 10', to receive and afford clearance for the flange of bushing 6. The reduced end of the escutcheon is formed with a relatively deep concentric cavity 10a, into which the outer end of the sleeve 7 projects, and to this end of the sleeve is threaded a, spannermut 12, for clamping the escuteheon against the outer face of the tank. The nut 12 only partially fills the socket 10a and is preferably formed with a round face that lits 'ball-like into the socket 10', the stem 9 projects a considerable distance-beyond the escntcheon and its outer end is inserted axially in a substantially globular head-piece 13, which is formed with a relatively deep socket 13 to receive the stem. At one side the head-piece is formed with a reduced cylindrical portion, as 13a, and this portion is inserted loosely and axially in the socket 10, and preferably lightly contacts with the outer face of` the spannernut 12, so as to avoid frictional wear and abrasion ot' the parts. The globular portion ci' the headpiece is formed with a circular socket, as 13b and with a concentric opening 13, which connects the tivo sockets. llrepresents a vitrified handle, by which the flush valve operating mechanism is manipulated. One end of the handle is formed, with a molded axial socket, 111/, in which is permanently embedded1v a metal connecting rod 15, in such manner that the 'free end of the rod, which is preferably threaded, may be inserted through the socket 13'), and the opening 13C, and thence into a transverse threaded hole 9:l of the stem, as best seen in Fig. 3. When assembling the handle and headpiece, a washer 1G, preferably rubber or leather, is usually lirst inserted in the socket 13b, so that when the handle is screwed up tight the china ot' the handle insulated fronrthe china. head-piece 13, for preventing abrasion when lthe parts are tightened.

By the construction and arrangen'ient of the parts, as described. there is an all-metal connection starting with the rod 15, throughoutthe train of parts, to the lift-rod l. rlhis arrangement is provided 'for the purpose of enabling the users ot the toilet to operate the flush-valve even though all of the china parts should be 1broken or destroyed, and it Will also be understood 'that none of the movable china parts are allowed to make direct rictional Contact with each other either, during the assembling or the subsequent operations of the ilushing mechanism.

The head-piece 13 performs a valuable and material function, in that it cooperates with the stem 9, for operatively supporting the handle 14, and also contributes greatly to the ornamental appearance of the external parts of the itting, since the handle, the head-piece, and the escutcheon are all made of china, and correspond with the viti'ilied tank 2, which is very desirable.

Having thus described my invention, what l claim, is

1. As a new article of manufacture, a head piece for the handles of flush valve operating mechanisms having stems for actuating the valve, including an integral globular vitrilied body having a cylindrical neck projecting outwardly vfrom a side oi the body, said neck having a stem-receiving socket extending from its outer end into the body, the body being formed with a recess in its periphery arranged in substantially the plane ot' the adjacent side of the neck and disposed at right angles to the socket and being iurther formed with an opening extending `lrom the recess into the socket.

2. A head piece for the handles ot V[lush valve operating mechanisms having stems 'lor actuating the valve, including an integral globular vitrilicd body having a cylindri 'al neck projecting outwardly from a side of the body`r said reck having a stemreceiving socket extending from its outer end into the body, the body being Yformed with a recess in its periphery airanged in substantially the plane ot the adjacent side ot' the neck `and dixposcd at right angles to the socket and being Yfurther formed with an opening extending` from the recess into the socket, and an escutcheon for the headpiece including a circular body having a central axial opening and having a concentric socket atone end to receive the neck ot the head piece, the bottom wall ofthe socket being concave, the lopposite end of the body being formed with a circular cavity surrounded by an annular face which latter is concaved to contormablyseat against the convex outer faceot a lush tank.

In testimony whereoitl I a'tliX my signature.

BERT O. TILDEN.
