UNITED sTATEs PTENT oEEIoE.
ALBERT H. JUDD, OF MARINE TOWN, ILLINOIS.
WATER-LEVEL INDICATOR FOR STEAM-IBOILERS.
Specification of Letters Patent No. 8,273, dated August 5, 1851.
T0 aZZ whom t may concern:
Be it known that I, ALBERT H. JUDD, of Marine Town, county of Madison, and State Aof Illinois, have invented new and useful Improvements in Float-Indicators of Steam- Boilers; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification.
Figure l, is an end view of a steam boiler, showing the index of my improved water gage, and graduated arc for measuring the height of the water within the boiler; Fig. 2, inner sectional view of a portion of the boiler, exhibiting parts of the water gage and their position when the index is at zero; Fig. 3, horizontal section of the same portion of the boiler in the line A, B, of Figs. l, and 2.
Like parts in the several figures are designated by like letters.
I place a gage cock z, Ze, 2'-, in the head of a boiler -in any well known or usual man ner; and to the outer end of the valve rod 7L, I secure the index Z. On the outer side of the head of the boiler, I figure (or secure thereto) a spaced and numbered arc m, to enable the index Z, to point out the height of water in the boiler. Within the boiler I place a shaft d, in the bearings e, which bearings are secured to the side of the boiler in such positions as to bring the said shaft in a line with the axis of the valve h, of the aforesaid gage cock. A slit or mortise g, is formed in one end of the shaft CZ, into which a tenon f, on the inner end of the valve h, of the gage cock, accurately fits. Then the valve ZL, is forced outward firmly into its seat, the tenon on its inner end is partially drawn out of the slit or mortise in the shaft CZ, which enables the valve to be forced inward whenever it may be Anecessary to aid in indicating the height of water in the boiler, or for preventing it from getting too firmly fixed within its seat. Arms c, project from the shaft LZ, to which a hollow metallic float a, is secured, which is located above the space between the two iues 6, b. The shaft CZ, is so arranged within its bearings that it can turn freely therein. As the surface of the water in the boiler rises and falls the float a, ascends and vdescends with it, and consequently turns the shaft CZ, and the valve 71., of the gage cock within their bearings. Thus the float, as it rises and falls with the water in the boiler, communicates its motion to the index Z. The arc m, is so graduated that the index points to zero when the surface of the water in the boiler is even with the top of the flues Z), Z), and in dicates by figures the number of inches which the water rises above the said flues. The float a, is placed directly over the space between the iiues in order that the concentrated current of steam, as it rises through the water in this space, may agitat-e the float and thereby communicate a trembling motion to the index.
In my improved gage, any obstruction to its free act-ion is indicated by the cessation of the trembling motion of the index, and may be immediately remedied by pushing in the valve ZL, when steam (or water) will be forced out through the aperture in la, and remove the impurities that have accumulated about the valve.
IYhat I claim as my invention and desire to secure by Letters Patent, is-
The connecting the ordinary float placedy within a steam-boiler with an index placed on the out side of the same, through the Inedium of the valve of a gage-cock, by which I am enabled to remove any impurities which may at any time hinder the effective action of the float substantially as herein set forth.
The above specification of my improved water gage for steam boilers signed this 21st day of May 1851.
ALBERT H. J UDI).
