TANK-FLOAT.

Patented June 8, 1909.

Application filed. August 80, 1905. SerialNo. 276,891.

To all whom it may concern:

Be it known that I, FREDERICK M. STEVENS, a citizen of the United States, residing at Waterbury, in the county of New Haven and State of Connecticut, have invented a certain new and useful Im rovement in Tank-Floats, of which the fol owing is a full, clear, and exact description.

The sheet copper balls used as floats in water-closet and other tanks for automatically closing the tank-filling valves, are commonly furnished to the trade in halves, ready to be closed andsoldered together, and the spud to receive the operating lever or rod is then soldered on. Spuds have been applied also by a rivetin or heading-up process.

The object oft is invention is to provide a spud for such floats, which may be secured in place against turning, before the halves are united.

The invention stated specifically consists of a tank float, having a spud provided with one or more projections arranged inside the float and expanded, swaged down or riveted down upon an inside washer, as I will proceed now more particularly to set forth. and finally claim.

In the accompanying dra s illustrating the invention, in the several views of which like parts are similarly designated, Figure 1 is a side elevation with the lower part in transverse section. Fig. 2 is an enlar ed vertical section of one side of the float. l ig. 3 is an enlarged vertical section of the other side of the float. tion of one form of spud detached, and Fig. 5 is a longitudinal section of another form of spud detached. Fig. 6 is a cross-section of the lower part of one of the halves of the float showing a modification in the manner of attaching the spud. Fig. 7 is a perspective view of another form of spud. Fig. 8 is a longitudinal section of the s ud of Fig. 7. Fig. 9 is a section similar to i 6 showing the spud-of Figs. 7 and 8 applied. and also' showing a modification in the construction of the lower portion of the float.

The two halves 1' and 2 ofthefloat are alike, and each comprises a hemis herical shell of copper or other non-corrodib e metal or substance, having half of its edge provided with a plain, straight flange 3 projecting therefrom at right an Ice to its axis, and a pocket-flange 4 similar y projecting from the other half, so that when these halves are in- Fig. 4 is a longitudinal secvertedly arranged and their flanged edges brought into parallel planes and the halves then moved toward each other, the plain flanges willslide into the pocket-flanges of the respective halves, after which these pocket-flanges are closed down upon the plain flanges and solder is applied to the joint thus formed to secure it an make the joint fluid-tight.

Before the halves are united, the spud 5 is applied to one of them. Various forms of .spuds and means of attaching them are own. All of these spuds, however, are

alike in having a shank 6 screw threaded internally at 7 a sufficient depth to receive a rod or lever by which the float isappli'ed for use.

Referring to Figs. 1,4, 6, 7, 8 and 9, the

shank terminates in a solid head having a side u on which the spud-projectipn is riveted own, and suchwasher or reinforce is shown at 11 in Figs. "1, 6 and 9. The shell and the washer'are perforated for the passage of the projection;

Instead of using onepro'ectiou, a number of projections may be use as two, in Figs. 7, 8 and 9, anddesignated 12, and the advantage of using two or more projections is t at the tendency of thespud to turn when e rod is. screwed home is obviated. The projections 12, also, may be cupped or hollowed out at their ends to facilitate the expanding,

swaging down or riveting of the projections when applying the spud.

I Instead of making the spud with three diameters, as shown in Figs. 1, 4 and v6, it may be madeof'two diameters as shown in Fig. 5, and in this instance, the shank and the flange 13 are of a single diameter and integral.

For further securing an air-tight and a fluid-tight joint, a washer 14, Fig. 1, of some soft material, may be inter osed between the flan e and the seat; or as s own in Fig. 6, the spu may be painted with some suitable substance 15, for the same purpose.

The halves may be nested together for economy in packing and transporting, and the shells constituting theses halves may be made plain or corrugated, and their ends formed as in Fig. 1 or Fig. 9; but the present invention is not limited to the construction of the shells of the float, and the invention is applicable to floats generally.

he particular construction of shells herein shown, with the provision of a spud of some sort, constitutes the subject of my patent for tank floats, dated August 28, 1906 No. 829,554.

What I claim is 1. A tank float, having a number of per forations at 'one end, and a spud having a shank provided with a screw-threaded socket and terminating in a solid head, a spreading flange projecting from said head and arran ed outside said float, and a number of solid projections upon said flange extendin through the erforations in said float an clenched against the inside of said float, Wherebythe spud is prevented from turning with relation to the float in applying and removing the float rod.

2. A ta'nkfloat, having a number of perforations at one end, a correspondingly perforated Washer arranged inside the float and next to its perforated end, and a spud having a shank provided with a screw threaded socket and terminating in a solid head, a spreading flange projecting from said head and arran ed outside said float, and'a number of so id projections upon said flange passing throu h the corresponding perforations in the fl dat and its contained Washer and clenched inside of the float a ainst said washer and adapted to prevent t e turning of the spud with relation to the float in applying and removing the float rod.

3. A tank float, having a number of perforations at one end, a correspondingly perforated washer arranged inside the float and next to its perforated end, and a spud having a shank provided with a screw threaded socket and terminating in a solid head, a spreading flange rojecting from said head and arranged outside the float, and a number of solid projections on said flange having cupped ends passing through the corresponding erforations in the float and its contained Washer and clenched inside of the float against said washer and adapted to prevent the turning of the s )Ud with relation to the float in applying and removing the float rod.

4. A tank float, having a shell provided with a depressed seat, a washer arranged inside the shell next to said seat, said seat and washer being provided with registering perforations, and a spud having shank provided with a screw threaded socket and terminating in a solid head, and a spreading flange projecting from said head to lit in said depressed seat, a packing interposed between sald flange and seat, and a pro ection on said head extending through the shell into the inside of the float and corresponding with and engaging the perforations in the seat and Washer and clenched on the inside of the shell against the washer.

In testimony whereof I have hereunto set my hand this 28th day of August A. D. 1905.

FREDERICK M. TEVENS.
