FLOAT.

Specification of Letters Patent. Application filed February 27, 1908. Serial No. 418,025.

PatentedAug. 9, 1910.

To all whom 'it may concern:

l 3e it known .that I, BERT O. TILDEN, a citizen of the-United States, residing in New vYork, borough of Manhattan, in the county I of New York and State of New York, have invented certain new and useful Improvements in Floats, of which the following is a specification.

The present improvement relates to floats, and has for an object to provide an air tight hollow nnperforate clay float, particularly such as is adapted for use with'water tanks,

such for instance as water closet tanks, and

one which may be supported forv rotary motion on its support.

A further obj ect of the invention is to provide an improved support for such ball or float whereby the same may be revolved when coming in contact with the side of the tank to decrease the frictional resistance occasioned thereby.

In the drawings accompanying and forming a part of this specification, Figure 1 is a perspective view of a practicable embodiment of a form of my improved float and its supporting means attached in position. Fig. 2 is a view of the supporting means detached; and Fig. 3 is an axial cross sectional view of the float with its supporting means attached.

Heretofore it has been impossible .to produce an imperforate hollow vitrified clay body. My float is a hollow vitrified impervious clay body without any openings whatsoever through its walls.

Various attempts have been made to produce a water tight hollow float and a support for the same so that the float could rotate upon the support. Particularly in water closet tanks it is desirable that the float be permitted to rotate upon its support as it rises and falls so as to remove friction and thereby prevent bending of the parts or the destruction of the float. None of these previous devices in practice proved to be water tight.

In the present illustration the float shown at 2 is a molded vitrified clay body, hollow,

and without openings through its walls. The float illustrated is made up of two halves, 3 and 4, which are molded from suitable ceramic material, and after having been thoroughly dried and joined together are fired after the manner of firing for producing vitrified china. The two halves are joined together by the use of a suitable intermediate strip of clay placed upon or between the meetlng edges and the said meeting edges forced together upon this inter mediate strip. If the entire circumference of the meeting edges were covered with this intermediate strip of clay and the two halves forced together such intermediate strip would be forced outward by the compression within the body. The strip of clay will ordinarily be laid upon the edge of one of the halves and an interruption or opening made in it by some suitable device, as for instance a piece of wire. The two halves are then brought together in proper relative positions and are forced together. As they are being forced together the'air which otherwise would be compressed escapes through this opening, and at the time the meeting edges are about in their final positions the outgoing air and the force of the coming together of the edges will close up the place where the opening was, and by the time the body is ready to be put into the kiln there will be no opening or perforation whatsoever throughout the entire walls. The float resulting from the baking or firing will be a hollow, imperforate, impervious, vitrified body.

For the securement of the supporting device in a manner to permit rotation of the float the float is usually provided at its opposite side with recesses 5 and 6 formed therein during the molding of the halves. These recesses are for the reception of the support. The support in the present in stance comprises a rod 7 having its end terminating in a resilient float supporting portion shown herein as substantially U-shaped, as at 9, and preferably conforming to the shape of the float. The rod in the formation of this U-shaped or supporting portion of the float is bent backwardly upon itself, as at 8, and has its free or opposite end bent inward, as at 10, thereby forming a pair of point members or projections adapted to enter the recesses 5 and 6 in the walls of the float to support the same. Attachment of the float to the support will be readily attained by springing the U-shaped portion of the rod into position upon the float whereby, as will be readily seen, the float is freely revolved, so that upon coming in contact with the walls of the tank it will be free to rotate during its upward and downward movements. This mode of connection, it will be observed, provides a support which may be fastened to the float without impairing its rotary movement and also without the necessity of providing holes in the walls of the float.

I claim as my invention: r

1. A hollow air-tight'float made of a fired vitreous material and free of any opening or core through any of its walls.

2. A hollow imperforate clay float free"o f any'opening or core through any of its walls.

- 3. float comprising a hollow, integral, imperforate, air-tight, fired clay member having integral portions for the attachment of a supporting member. I

4. Afloat comprising a hollow, integral, imperforate, air-tight, fired clay member having opposed recesses in its walls for attachmentof a supporting member.

5. A float comprising a hollow, integral, imperforate air-tight, molded and fired clay member having molded portions for the attachment of a supporting member.

6. A float comprising a hollow, imperforate air-tight, integral molded and fired clay member having a pair of opposed molded recesses for the attachment of a supportin member.

A hollow, imperforate float, and means for supporting the same comprising a rod having resilient clamping portions to engage; the opposite sides of saidfloat without passing through the walls thereof.

8. A hollow, imperforate float, and means for supporting the same comprising a rodi bent to partly encircle said float and having? resilient clamping portions adapted to engage opposite sides of said float without l passing through the walls thereof.

9. A "hollow, integral, imperforate airposedlmolded recesses in sides, and supporting means therefor comprlsmg a rod bent to partly encircle said float and form a resilient clamping portion provided with projections extending into the recesses of said float.

, 10. A supporting member for a float of the class described, comprising a rod having a portion bent to form a U-shaped portion and a pair of projections adapted to engage a float, said rod having a portion thereof bent upon itself to form one of said projections.

. 11. A hollow, imperfora'te air-tight, integral, molded and fired clay float member, and a supporting member having a resilient part adapted to partly encircle and clamp said float member, one of said members havof the other of said members.

12. A float of the class described, comprising an integral, air-tight, molded member, and supporting means comprising a rod having a part adapted to be sprung around and partly encircle said float member, one of said members having means for receiving projecting portions of the other of said members.

13. A float of the class described, comprising an integral, air-tight, molded clay member having opposed recesses in its outer walls, and a supporting member comprising a rod having a portion bent to be sprung around and partly encircle said float member and provided with, projections extending into the recesses of said float member, said rod having a part thereof bent upon itself to form one of such projections.
