or said hoop may be first soldered or otherwise securely attached to the edge portion I) and the edge portion b forced into place over the hoop. At the time of assembling contacting surfaces vof the edge portions with each other and with the hoop and diaphragm are soldered or otherwise securely united, although it may not always be necessary to attach the hoop and the diaphragm to the edge portions by other means than that afforded by the nature of the construction of these parts. After being assembled the joint and oat are completed by depositing a coating c' over the outside of the sections a and a', including the edge portion 7e now have a float which possesses all of the advantages hereinbefore enumerated.
The presence of the diaphragm, together with the means of connection, enables us to use very thin metal for the parts, and the eX- ternal plating or coating not only unites the sections into a homogeneous mass, as it were, but serves to remove inequalities in the outside surface and to bring the oat up to the required weight. The coating also assists in holding the sections together and'preventing the opening of the joint and renders the fioat seamless. rlhe diaphragm offers strong' resistance to outside pressure, while the hoop and coating offer like resistance to both inside and outside pressure, and all together they produce the desired results. Furthermore, the exterior bulging belt comprising the overlapping edge portion, with its offset and hoop, receives whatever wear the fioat may be subjected to by being rubbed against the side of the tank or'other receptacle in which said ioat is located, and said hoop, with the diaphragm, protects the float from harm when it sustains a blow.
As shown in Fig. 3, the bead c may be of suiicient size to receive a second hoop c, which still further stiffens the construction. Other hoops may be utilized, as before inti* mated, and of course the diaphragm might be duplicated; but for all ordinary purposes it -is believed no such additional members need be employed.
The holes in the diaphragm need not necessarily be round, nor the hoops half-round in cross-section, and we do not desire to be restricted to any particular kind of float, but seek to include within the scope of our invention and claims any jointed sheet-metal float or similar device.
Copper is probably the most practical metal of which to make our float throughout; nevertheless some other metal can be used for the diaphragm, in which event the latter should not be soldered to adjacent parts of the edge portion b, andsuficient clearance should be left between the edge of said diaphragm and the groove in the portion formed by the bead c and the flange d, to allow for any difference there may be in expansion and contraction between the two metals.
What we claim as our invention, and desire to secure by Letters Patent, isPq l. As a new article of manufacture, a iioat having a diaphragm therein and provided with means to hold said diaphragm in place.
2. As a new article of manufacture, a float havingwa perforated diaphragm therein, the edges of the perforations in said diaphragm being swaged or turned out.
3. As a new article of manufacture, a float having' a diaphragm therein and provided with means to hold said diaphragm in place, clearance being left between the edge of the diaphragm and adjacent parts of the ioat to allow for expansion and contraction.
4. As a new article of manufacture, a float having certain portions which are meridionally straight and provided with an internal diaphragm and means to hold said diaphragm in place.
As a new article of manufacture, a oat comprising sections having lapped portions, one of lsuch portions being provided with a bead and a flange, and an internal diaphragm held in place by said bead and flange.
6. As a new article of manufacture, a oat comprising sections having lapped portions with a hoop between such portions, an internal diaphragm, and means to hold said diaphragm in place.
7. As a new article of manufacture, a float comprising sections having lapped portions with a hoop between such portions, an internal diaphragm, means to hold said diaphragm in place, and a coating or deposit over the outside' of all.
In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
