IMPROVEMENT IN BOILER SAFETY-GAUGES.
TO ALL WHOM IT MAY CONCERN:
Beit known that I, R. H. JACKSON, of Sandusky, in the county of Erie, andState of Ohio, have invented certain new and useful improvements in Steam Boiler Safety-Gauge; andl do hereby declare that the following is a full and complete description of the construction and-operation of the same, referencerbeing had to the accompanying drawings, making a part of 'this specification, in which- Figure 1 is a front view of the gauge.
Figure 2 is a side view.
Figure 3 is a top view. v 4
Figures 4 and 5, detached sections to which reference will' be made.
Like letters of reference refer to like parts in the several views.
This apparatus consists of a cylinder', A,'g. 1, to the top B of which is screwed a small or supplementary cylinder, C, in which is fitted a solid piston, indicated'by the dotted lines a, lig. 1, and of which E is the rod. To the lower end of the cylinder A is attached arpipe, F, which reaches to the boiler G, into which it descends to the water space below the flues H, as indicated by the dotted line a. This pipe is provided with a' stop-valve, I, iig. 5, operated by the hand-wheel I. From the upper end of the cylinder project the elbows J J. To the elbow J is attacheda pipe, K, which reaches to the boiler, and is projected into the same near to the top of the ilues, as indicated by the dotted line b. AThis pipe is also furnished with a stop-valve, in construction like the one above referred to, and operated in the saine way, by a hand-wheel, K. To the elbow J is attached aA pipe, L, which reaches to the boiler, and opens just within the shell, as indicated by the dotted line c. This pipe is also provided with a stop-valve, constructed and operated in the same lmannerlas the valves in the pipes referred to. Dependent from the under side of the top orcover of the cylinder A is a lug, M, g. 4, from the inner side of which projects an arm, M. ln the end of this'arm is pvoted a lever, N, to the long arm of which is suspended ailcat, N', by a rod, vO. To the upper sido of the erm M is tted a slide valve, Oi', and which is connected to the minor arm of the lover N by a link, P, and operated by the same, as will hereafter be shown. This valve is kept down upon its seat by a spring, P, and covers a small port leading from the cylinder A into the supplementary cylinder C. Said opening is indicated by the dotted line In the drawing the apparatus is represented as being placed directly over thc boiler, and immediately connected to the same by short straight pipes, but lit is not anecessity that it should be placed in this position, it being shown thus simply for the convenience of illustration. The intention'is to place this gauge in the pilot-house on water-crafts, some ten, twenty, or even fifty feet above the boiler, and in charge of the captain or pilot; also to beplaced in the oiices adjacent to stationary engines, and not left to the exclusive care o f engineers, who, in case of waterfalling below the point of safety in the boiler, are seldom willing to make the fact known until too late. The apparatus when placed thus distant from the boiler is connected to the same by a range of pipe in such a way as the nature of the circumstances may demand. The fire-place and boiler are vconnected to each other by a steam pipe, which pipe is provided with a stop-valve, and is connected by means of a chain or rod to the endl ofv the piston-rod referred to as being in the cylinder C.
Having thus indicated the construct-ion of the apparatus, and. its relation to the boiler, the practical use and operation of the same are as follows 1 The boiler on being filled up with water to the usual level, and steam generated, water will be forced up into the cylinder A, through the pipes-F and K, thereby raising the float N', and closing the port communieating withthe cylinder C by the valve O. So long as the water in the boiler is above the point of danger the port remains closed, but as soon as 4it falls below that point, or on a level with the top of the ilues or crownsheet, and hencebelow the end of the pipe K, and which is the point of danger, steam is admitted into this pipe K, through which it passes into the cylinder A, forcing the water bac-k into the boiler through the pipe F; in consequence the oat falls and opens the port, through which steam rushes up into the cylinder C, the piston in which is thereby pushed up, and opens the valve in the pipe by which the boiler and fire-place are connected, as above said, and through which pipe water from the boiler rushes into the furnaces and extinguishes the fires. The boiler on being again lkilled to its proper .level and the steam lexhausted from the cylinder A, the iioat therein will rise up by the Water flowing into it from the boiler, in the monner as above described,uand thereby Will close the port d by the valve Of, and thus stmt off the vcommunication 'between the two cylinders, which will again be opened in case of flangerin the same Way as before instanced. .When there is no steam up, and hence no pressure on the boiler, the water in the 'Cylinder A` Will fell back into the boiler, thereby preventing the adhesion of the valve O to its rest. The purpose of the` velve I is to gauge or regulate the omount of Water` to {low into the cylinder A, and, if required, vshut oi all commimication with the boiler.
What I claim as my improvement, and desireto secure by Letters Patent, is- 1.\ The pipes K, F, and L, es arranged in combination with the cylinders A and G, and boiler. G, for the purpose and in the manner described. l
2. The Valve O', when arranged and operated by the lever N und iloat N', when in the relationsy to. the
piston a substantially as and for the purpose set-forth.
R. H. JACKSON.
