FLOAT FOR CONTROLLING SHUT-OFF VALVES.

SPECIFICATION formingpart of Letters Patent No. 687,625, dated No ember 26, 1901.

Serial No. 70,035. (No model.)

To all whom it may concern:

Be it known that I, WINFIELD E. HINSDALE, a citizen of the United States, residing at New York, in the borough of Manhattan, county and State of New York, have made a new and useful Invention in Floats for Controlling Shut-Off Valves, of which the following is a specification.

My invention is directed to a novel form of float for use in connection with shut-01f valves-such, for instance, as are found in cistern watecclosets and railway and other water-tanks-in short, in any place where it is desired to have the flow of water controlled by the action of a float when it (the water) reaches a certain level. I

My invention will be fully understood by referring to the accompanying drawings, in which- Figure 1 is a side elevational view of my improved float. Fig. 2 is a side elevational View as seen looking at Fig. 1 from the bottom toward the top of the drawings, the means for attaching the valve-controlling rod to the gripping or supporting band about the float being shown in sectional view, a part of the float being broken away and also shown in sectional view for the purpose of more effectually illustrating the invention. Fig. 3 is an end elevational view as seen looking at Fig. 1 from right to left, the body of the float proper being shown in dotted lines.

Shut-0E valves have heretofore been controlled by means of floats made of thin sheet metal, such as copper, in the form of two hemispherical cups, said cups being soldered together and attached to a valve-controlling rod. This type of float, however, is faulty in i that the acids and other materials usually fact the imperfect deposition of the electroplating material often leaves points of attack for the acids in the water, so that they are open to the same objection as are the twopart cups first described. A still further novel form of float has been constructed, consistin g of a hollow glass ball having a molded neck threaded exteriorly, to which threaded neck a coupling and valve-controlling rod are attached. In the construction of this float, however, the neck and the hall are made separate and afterward fused together. A brass coupling screw-threaded interiorly is then secured to the threaded neck and the valvecontrolling rod in turn secured to the coupling. In fusing the glass parts together the best joint is not always effected, and it is found in practice that the neck and the ball often become'separated, thus making it worthless. My improved form of float is designed to overcome all of these objections and will be fully understood by referring now to the accompanying drawings in detail, in which- A is a hollow glass ball so constructed when blown as to have two heads B B located on opposite sides ofits equator, thereby leaving a groove or channel G for receiving a drawband D, provided with holes or openings at its opposite ends adapted to receive screws F F, extending into lugs or extensions E E of a coupling-piece G. This coupling-piece is in turn screw-threaded, as shown, so as to receive one end of the valve-controlling rod R, having screw-threads at its opposite ends and adapted to be secured to the valve-rod or other attachment ordinarily used in connection with such devices in the usual way.

In putting this float together the ends of the draw-band D are bent outward, as shown in Fig. 2, and it is laid in the groove C between the beads B B, one end thereof being secured by one of the screws F directly to the coupling-piece G, after which the' other end is drawn into position and the second screw F secured in place,there being sufiicient draw or tension upon the band D and couplingpiece G when the screws are firmly set to cause said band to firmly grip and secure the coupling-piece against the ball, after which the valve-controlling rod is secured in place and the completed article is ready for trans portation and use.

' I am aware that it is old in the art to support a glass-ball float by a series of curved rods or arms of metal secured to a valve-controlling rod or lever by a set-screw, as disequator; together with a surrounding grip-- closed in United States patent to G. B. Moore, No. 588,461, granted August 17,1897, and that it is also old to support metallic-ball floats made in two parts, such as. hereinbefore referred to, by a studded disk and straps or bands which surround and secure the ball to the disk, as disclosed in United States patent to V. D. Anderson, No. 640,073, granted December 26, 1899, and I make no claim hereinafter broad enough to include such structures.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. As an article of manufacture a hollow glass float provided with a groove around its ping-band provided with holes at its opposite ends, a coup1ing-piece and screws for securing the opposite ends of said band to the V coupling-piece, substantially as described.

2. As an article of manufacture a hollow glass float provided with a groovearound its equator, a surrounding band provided with holes at its opposite ends; a coupling-piece, screws for securing the opposite ends of said band to the coupling-piece and a. valve-controlling rod secured to the coupling-piece, substantially as described.

3. As an article of manufacture a hollow glass float A having a groove or channel 0 in the plane of its equator; a surrounding grip ping-band D provided with holes at its opposite ends; together with a coupling-piece G, screws F, F adapted to secure the opposite ends of said band to the coupling-piece and a valve-controllin g rod B provided with screwthreads at its opposite ends for securing one end to the float and the other to the valve to be controlled, substantially as described.

4. As an article of manufacture a'glass float A having a groove or channel Gin the plane of its equator; a surrounding gripping-band D provided with holes at its opposite ends; a coupling-piece G having an extension or neck screw-threaded internally; screws F, F adapted to secure the opposite ends of the gripping-band directly tothe coupling-piece; together with a valve-controlling rod screwthreaded at its opposite ends in such manner that one end thereof may be secured directly to the neck of the coupling-piece and the other to the valve to be controlled, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

WIN FIELD E. HINSDALE.
