UNITED STATES PATENT OFFICE.
RECORDING PRESSURE-GAGE.
SPECIFICATION forming part of Letters Patent No. 287,686, dated October 30, 1883.
Application filed June 14, 1883. No model.)
To all whom, it may concern Be it known that I, FLORENTINE A. Jonns, of the city, county, and State of New York, have invented new and useful Improvements in Recording PressureGages, of which the following is a specification.
This improvement relates to gages for showing the extent and variations of pressure in steamboilers, cylinders, or other vessels containing air, gas, liquid, orother fluids.
The accompanying drawing shows a plan view of my improved recording pressure-gage with the dial of the gage-box removed.
A and A are boxes secured to each other by the connection 13, which has a passage, B, for the accommodation of the connecting mechanism.
In place of the ordinary Bourdon tubular spring, which has been heretofore used in the gage-boX, I employ the double tubular spring O O, acting on the same general principle as the usual Bourdon spring. This spring may be integral, receiving through a single aperture the steam from the hollow plug P, or the parts 0 and C may be separate, each connecting with said plug 1?.
E is the ordinary mechanism of a steam gage, consisting, essentially, of a segmental rack, D, pivoted near its rear end at d, and meshing intoa pinion carrying a pointer. (Not shown in the drawing.)
G is a bifurcated lever, having its branches pivoted at g g to the parts 0 O of the spring, and connected with the rack D by a link, H, pivoted to said rack and bifurcated lever. Thus the spring 0 O imparts motion to the mechanism E, which gives movement to the pointer, showing, in connection with the dial, the steam-pressure.
I is a dial rotated by a clock-movement, and
having uponits surface twenty-four radial curved lines, a, corresponding with the number of hours in a day, and ,a certain number ofconcentric circles, b, corresponding with the pressure indicated upon the dial of the steamgage. K is a lever, crooked for convenience, and pivoted at k to the standard L, so as to freely swing back and forth, and provided at its free end with the marker 0.
N is a connecting-rod pivoted to the lever K, and to the rigid projection R, immovably secured to the link S is a slot in the lever K, by means of which the point of attachment of the rod N may be changed at will.
I11 operation, as steam or other fluid enters the double hollow spring or springs O O through the plug P, the pressure on the inner surface of the spring or springs causes expansion, forcing the free ends of the parts apart, or contraction, drawing said free ends toward each other as the pressure is greater or less; and this movement is communicated by means of the bifurcated lever G, link H, rigid pro j ection R, and rod N to the lever K, thus causing the pencil e to vibrate with the movement of the double spring, and with the pointer on the dial of the steam-gage, and give a delineation of the pressure and the time of any change therein on the dial I, which is arranged to rotate once in twenty-four hours.
The connecting mechanism between the spring and the lever K may be subjected to various modifications, one of which is indicated by the broken lines V, which represent a link connecting directly the lever G and lever K.
The double Bourdon spring, bifurcated lever G, and link H, connecting the latter with the rack D, are not novel in this invention.
Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is
1. In a recording pressure-gage, the combination of the following elements, viz: the double tubular spring or springs O O, suitably secured therein, a multiplying delineating-lever extending to the recording-surface, and suitable intermediate mechanism, whereby motion is transmitted from said spring or springs to said lever, substantially as and for the purpose set forth.
2. In a recording pressure-gage, the combination of the following parts, viz: a suitablysecured double tubular spring or springs, O O, the bifurcated lever G, the link H, provided with the rigid projection R, rack D, link N, lever K, provided with an indicating or delineating device, and a suitable surface for the recording of the pressure, all arranged and constructed substantially as and for the pun pose described.
