Description
HENRYaMGANN,or
cLEvELAND,oHIo
Letters Patent No. 84,502, dated December l, 1868.
l'lMlPROVEIWIEINT IN FLOATS FOR BOILERS.
The Schedule referred to in these -Letters Patent and making part of the same.
To all whom ct lma/y conce/rn:
Be it known that I, HENRY MGGANN, of Cleveland, in the county of Cuyahoga, and State of Ohio, have invented certain new `and useful Improvements in Floats i'or Steam-Boilers; and I do declare-that the following is'a full and complete description of the same, reference being had to -the accompanying drawings, making part of this specification, in which- Figure l is an outside view` of the float.l
Figure 2, a view of the float with a section of the shell detached.
Figure 3, a view of the frame.
Like letters of reference refer to like parts in the diierent views. v
The nature of this invention relates to a float for steam-boilers, constructed with an internal globular frame, whereby the shell of the oat is prevented fromcollapsing in consequence of the pressure of steam exerted upon it.
The oat referred to consists vof an external thin metallic shell, A, iig. l, to which is attacheda rod, B, whereby it is connected to the axial point of vibration. Within said shell is closely iitted a globular metallic frame-work, C,f1g. 3, whereby the outer shell is braced and thereby prevented from beingforced in or collapsed by the pressure of the steam to which it is subjected, and which, as ordinarily made, is very liable to become crushed in consequence of the thinness of the metal of which it is made. To obviate this diiculty the 'floatqhas sometimes been constructed of much thicker plate, so as to .enable it to resist the strain upon it. This additional thickness of the shell has so increased the weight of the iioat that, practically, it has been of little or no value for the loss of buoyancy,
which it is highly important that the shell shouldpossess.
By the use ofthe light globular frame C, closely iitted to the inside, as shown in fig. 2, the shell of the float can be madeof very thin plate,'and thereby retaiuall the buoyancy essential toits practical value, Y
and at the same time possessa strength of structure that will enable it to resist the great pressure of steam that may be exerted upon it.
This frame is easily made by casting it -in suitable moulds, provided with a core, whereby the openings or bars of the frame are formed; hence the expense of a oat thus constructed 4will be but little more than the ordinary one, and less expensive than thosermade of thick metal, Inore buoyant and durable.
What I claim as my invention, and desire to secure by Letters Patent, isx The globular frame C, in combination with the shell A, substantially as herein specified.
H. MCGANN.
