FLOAT FOE STEAIE TRAPS AND TEE LTKE.

Application filed October 5, 1921. Serial No. 505,524.

To all whom it may concern:

Be it known that 1, JOHN ROWLAND BROWN, a citizen of the United States, and a resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented anew and useful Improvement in Floats for Steam Traps and the like, of which the,

following is a specification, the principle of the invention being herein explained, and the best mode in which I have contemplated applying that principle so as to distinguish it from other inventions.

The present improvements relate more particularly to floats composed of an internal hollow foundation and an external seamless metallic shell or coating formed by electroplating such foundation. The latter may be formed of various materials as for example papier mach, celluloid and the like, and the coating will usually be of copper although nickel or other metals that are capable of being electro-deposited may of course be used. Still more particularly the present invention relates to the construction and manner of attachment of a spud to such float whereby the latter may be connected with suitable operating mechanism, such spud including either an internally or an externally threaded nipple.

To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims, and the annexed drawing disclosing but one of various mechanical forms in which the principle of the invention may be utilized.

In said annexed drawing Figs. 1, 2 and 3 are corresponding axial sections of the nipple, a plate for holding the same, and the hollow foundation or core of the float, shown in separate, i. e.. disassembled condition; Fig. I} is a similar view of the foregoing parts in assembled condition; Fig. 5 is a horizontal section through such nipple and plate in assembled condition, the plane of the section being indicated by the line 55, Fig. it; Fig. 6 is a bottom plan view of the nipple and holding plate; and Fig. 7 illustrates the adaptation of the device threaded nipple.

The core 1, while shown in Figs. 3 and t as of approxhnately spherical form, may of course take on any shape required by the for use with an externally exigencies of the use to which the completed" float is to be put. It is also a matter of indifference, so far as the present invention device of present interest is tote attached, such device being ordinarily termed a' spud in the trade. At this point the'core or shell 1 is formed with acircular aper ture 2 and surrounding such aperture the material is depressed to form an annular recess?) of the proper size and shape to receive a stamped-up metal plate 4. The latter is formed with a central hollow boss or depression 5 preferably of polygonal cross section and is adapted to receivea nip ple 6 that is formed with a head 7 of corresponding cross section. The depth of the recess in boss 5 is slightly greater than that of such head so that when the nipple is inserted the boss may be criinped inwardly at its base, as clearly shown in Fig. 4, and tliereby firmly secure the nipple 6 to the p ate.

Such nipple is shown as internally threaded but may obviously take the form of an externally threaded stud or any other form of connecting element may be utilized so long as it is provided with a suitable head adapted to be secured in the plate in the manner just described. Preferably for convenience in manufacture an internally threaded nipple will be employed as a standard fitting and where an externally threaded stud-connection 8 is desired, the latter will simply be threaded into such nipple 6, as shown in Fig. 7.

It will be observed that the plate 4- is imperforate and that the depth of recess 8 surrounding aperture 2 in the core corresponds with the thickness of the flanged portion of such plate. Accordingly when the latter is seated in the recess and there secured by a suitable cement, not only is the core completely closed, but the exterior surface thereof is left smooth and continuous insuring an even deposit of the metallic coating, when the latter is electrolytically applied, right up to the nipple 6 or equivalent con necting member. lVhether the joint between the latter and the plate 4: is perfectly sealed is a matter of indifference since the plate in itself affords a perfect closure for the core. The deposited metallic coating on the core being integrally united with the plate supplements the cement between the latter and the depression 3 and insures a very substantial and permanent mounting for the spud as a whole.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention 1. In a device of the character described, the combination of a hollow core having an aperture, a depression being formed in the wall of said core surrounding such aperture, a plate fitted in such depression and formed with an inwardly directed hollow boss received in such aperture, and a member providing external connecting means for said core secured in such boss.

2. In a device of the character described, the combination of a hollow core having an aperture, a depression being formed in the wall of said core surrounding such aperture, a plate fitted in such depression and formed with an inwardly directed hollow boss received in such aperture, and a threaded nipple providing external connecting means for said core, said nipple being formed with a head received in such boss and the latter being crimped inwardly at its base, whereby said nipple is firmly secured thereto.

3. In a device of the character described, the combination of a hollow core having an aperture, a depression being formed in the wall of said core surrounding such aperture, a plate fitted in such depression and formed with an inwardly directed hollow boss received in such aperture, and a threaded nipple providing external connecting means for said core, said nipple being formed with a head of polygonal cross-section received in such boss and the latter being crimped inwardly at its base, whereby said nipple is firmly secured thereto.
