ANDREW YOUNT, OF KOKOMO, INDIANA, ASSIGNOR TO HIMSELF AND JOHN CHANDLER, OF SAME PLACE.

IMPROVEMENT IN WATER-REGULATURS, INDlCATORS, AND LOW-WATER ALARMS.

Speciiicatlun forming part of Letters Patent No. 155,784, dated October 6, 1874 application filed i February 13, 1874.

To all whom it may concern:

Be it known that I, ANDREW YOUNT, of Kokomo, in the county of Howard and inthe State of Iudiana,have invented certain new and useful Improvements in Water-Regulator, Indicator, and Low-Water Alarm; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and Avto the letters of reference marked. thereon,

making a part of this speciiication.

The nature of my invention consists in the construction and arrangement of a combined water regulator, indicator, and low water alarm, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawings, in which- Figure 1 is a side elevation, partly in section, of a boiler with pump, heater, and tank embodying my invention. Fig. 2 is a perspectiye view of the indicator, part in section, to show the interior thereof. Fig. 3 is an enlarged section of the water-regulator.

A represents a steam-boiler, connected by a pipe, B, with a heater, O, which pipe connects the top of the boiler with the bottom of the heater. D is acold-water pump for pumping cold water into an elevated tank, G, the water passing from the pump through a pipe, E, into a pipe, El, and from thence into the tank. To the lower end of the pipe E1, below the entrance of the pipe E, is attached the water-regulator H, constructed substantially in the form shown in Figs. l and 3, and its lower end connected by a pipe, E2, with the heater C, at or near the top thereof. Within the boiler A is a float, I, from which. extends a rod, a, vertically upward through a pipe, J, .into an indicator-casing, K. The rod a is made in two sections, united together by means of a suitable coupling, b, so that to attach the float to the indicating mechanism it will not be necessary to getinside of the boiler. The upper end of the float-rod 'a is pivoted to the end of a lever, d, the other end of which is pivoted to one end of a short lever, d1. The

other end of this lever dl is pivoted to or on a pin or stud in the casing K. To the center of the lever d is pivoted one end of a lever, d2, which is curved, as shown, in semicircular form, and provided with journals e e upon a line with each other. These journals pass, respectively, through, and have their bearingsin, the front and back of the casin g K. On the front journal e is secured an index hand or finger, f, to show by the action of the float I, through the medium of the levers d d1 d2, upon the graduated or dial face of the indicator-casing, the state of the water in the boiler. On the end of the rear journal e is secured a lever, j", which is provided on its inner side with pins These pins, as the water recedes in thc boiler below low-water mark, or as it rises above high-water mark, act upon a lever, 7L, to operate the whistle L, placed upon and attached to the indicator K. From one end of the lever f a Wire or cord, m, extends to a curved or L-shaped lever, -M, arranged above the Water-regulator H. The other end of this lever is, by a wire or cord, m', connected with a weighted lever, N, placed upon the end of a shaft, n, which passes horizontally through the water-regulator H. In this regulator is a horizontal partition, O, with a longitudinal concavity in its under side, in which the shaft a is placed. In the partition O are two valveseats, x and m', one from the top and the other from the under side of the partition. On the shaft n is secured a lever, P, one end of which is provided with a valve, p, to iit in the valve-seat and the other end is provided with an upward-projecting stem, p2, carrying the valve p1 to fit in the valve-seat a.

The operation of this machine is as follows: The tank G and heater G being both full, and the requisite amount in the boiler A, the pump D is not in operation. As the water sinks in the boiler, the loat, by the connections described, raises the lever N, opening both valves p p1, and allowing water from the tank to pass into the heater, and from the heater it passes through the pipe B into the boiler, and as the water and float rise in the boiler, the lever N falls by its weight, closing the valves p p1, and so on, perfectly regulating the iiow of Water from the tank to the heater and the boiler.

The valves p and pl, being arranged one above and the other below the partition O, are perfectly balanced and kept closed by the pressure of Water from above.

By the arrangement of the levers d d* d2, the oat-rod a is allowed to move vertically up and down, Without any motion to either side, which admits of using a pipe or stein, J, for the indicator smaller than is usually done.

Having,` thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The levers d and d1, and bent lever d2, having journals e e', in combination with the ro'd a, float I, and nger f, as and for the purposes herein set forth.

2. The combination of the supply-tank G, heater C, interposed regulator H, with parti Jfion O, balanced lever P, with valves p pl, Weighted lever N, connecting-wires m m, elbow-lever M, lever f', indicator-shaft rod a,

and oat I in the boiler A, all constructed ANDREW YOUN T.
