SPECIFICATION forming part of Letters Patent No. 287,069, dated October 23, 1883.
Application filed July as, 1883. (No model.)
the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.
Figure 1 of the drawings is a side elevation V of my invention; Fig. 2, a detail view of the band, and Fig. 3 a cross-section of the steampipe through the line of perforations.
This invention relates to certain new and useful improvements in steam-pump regulators, the object thereof being to provide such a device simple in its construction and effective in its operation, toseeure a uniform pressure of steam, no matter what may be the resistance of the machinery or the amount in the boiler; and the invention consists in the gen eral construction and arrangement of the several operating parts, as illustrated in the accompanying drawings, and hereinafter more fully described.
In the drawings, A represents a pipe, through which the steam is admitted from a boiler to a reservoir, B, from whence it passes through perforations G into a pipe, D, said perforations being equal in number and equi distant apart to cause an equality of pressure, the pipe D being closed at its top and its upper portion surrounded by a band, E, provided with a bail, F. The steam 110w passes down the pipe D, on its way to the engine, and when it is desired to regulate the supplya valve, G, is turned, so that the steam may pass through as well as toward said engine.
. The steam thus passing through the valve G the boiler.
' pipe D, sothat,,if there is a high pressure of steam, the greater said pressure through the valve G upon the plunger H. the farther the band E will be closed over the perforations in said pipe D, thus shutting off steam in proportion to the amount of pressure on said plunger.
If there is lowpressure of steam, a spring, N, incased in a cylinder, 0, acts to force the lever K down, thus raising the band E and enlarging the perforations G in the pipe D, so that the pressure of the steam will remain the same, no matter what the amount may be in tween brackets projecting from a standard, 1?, to which is pivotally connected the lever 'K, and is secured upon the top of the reservoir B by set-nuts, forming a boxing for the rod M, said spring being provided with a follower, B, which rests upon said lever K, and is controlled by'a tension-screw, S, threaded in the upper bracket.
Should the spring N be insufficient to depress the lever, a weight, T, may be secured to the end of said lever to increase the downward pressure; and, indeed, it may be found preferable to always employ this weight.
Having now fully described my invention, whatI claim as new, and desire to secure by Letters Patent, is i Y 1. The movable band E, having a bail, F, secured to a rod, M, in combination with the pipe D, closed at its top and provided with an even. number of perforations equidistant apart, the reservoir B, having secured thereto a bracket, 1?, and the mechanism for erating said movable band, substantially as shown and described.
2. The lever K,pivotally secured to the standard 1?, and provided with depending rods L M, the former connecting with the plunger H and the latter with the movable band E, in combination with the spring N, incased between brackets projecting from the standard I and provided with a follower, R, and tensionscrew S substantially as and for the purpose specified.
3. The reservoir B, provided with an inletpipe, A, in combination with the pipe D,
This spring N is secured beclosed at its top and provided with perforahereunto subscribed my name in the presence 10 tions 0, the movable band E, valve G, plunof two witnesses.
ger H, rods L M, lever K, having a weight,
T, the standard P, provided with projecting 5 brackets} a spring, N, incased between said brackets, follower R, and tension-screw S, all
constructed and arranged to operate substan- W'itnesses:
tially as and for the purpose set forth. A. G. LUCAS,
In testimony that I claim the above I have J. M. WILFLEY.
