rMPRovED WATER-SUPPLY REG-Urhsr011;!

F CHICAGO, ILLINOIS.

atea December 22, 186s.

The B'ohedule refened to in these Letters Patent and mak-ing part of the same.

To all whom itmcy concern:

Be it known that I, GEORGE P.' NUT'rrNG, of Ohiinvented a new and improved Water-Supply Regulator; and I do hereby declare that the following is a full, clear, and exact description thereof, which willv enable others skilled in the artfto makeand use the same, reference being had tothe accompanying drawf ings, forming part of this specification, in which- Figure l is a vertical longitudinal section of my invention.

Figure 2 is a horizontal section ofthe same.

Similar letters of reference indicate like parts..

The object of this invention is to maintain the proper water-supply in boilers, by admitting. steam to the supply-pump, when the water reaches a certain level, aud also to announce to the'attendant the fact, the state of the water-level, when, for any reason, the supply-pump ilails to maintain the proper level.-

It consists in the arrangement of parts, as will be hereinafter more fully described.

A is a water-chamber, of metal, surmounted by a steam-chamber, B.

The water-chamber is, in practice, connected with the boiler by a pipe, C, located near the bottom of the boiler a little below the line of the proper water-level, to be maintained in the latter by the opening c, through which the rod d passes to operate the steamevalves in the steam-chamber.

D is a discharge-cock, for the water-chamber. E is a hollow iioat, of copper or othersheet-metal,

rlhe iioat is buoyant on the water, and is formed with a .concavity or recess on its under side, which recess, being filled with water, causes the float to respond 'l more quickly to the subsidence of the water in obedience to the vacuum induced in the recess by the said subsidence. f

The oat is attached, by a lever, G, to some fixed point within the chamber, as a lug on the steampipc H, which latter leads from thev boiler, and up through the interior of the water-chamber, and terminates in a valve-chest, I, with the inten'or of which it communi-- cates.

The upper side of t-hisv valve-chamber seats two conical or other lifting-valves, having their stems attached t o a lever, b, and, at equal distances 4on each 'side of the upright c, affording bearings for the fulcrum-pin, on which the said lever c vibrates.

The aforesaid rod d connects th lever G. l

` It will be observed that the steam-valves e e are reversed, one vopening downward and the ,other opening upward, and, in practice, the areas of the under side of the valves are equal, that they will bebalanced by the steam-pressure, thereby exerting no considerable e lever b with the a pin, h, on the rod d, when the latter is moved downward by the float when the water subsides to a'certain predetermined level, for which the mechanism was arranged, and in which case, the lever Lbeing. moved, the valve f will be moved from its seat, and the escaping steam will announce to the attendant that the water has reached a low level.

The whistle may be of anysuitable construction, the common pocket-whistle form being suiiciently loud for the purpose, `lalthough a steam-whistle of the common form is shown in the drawings. Either may be'used. M is a spring, actingv in the lever L, to keep the valve seated, 'when the lever L is not actuated by the pin `h, as above described.

When the water in the boiler begins to subside from the level at which it is to be maintained, the float will open the valves e, and admit steam to the chamber B, from which it ows'through the pipe J to the steampump, and sets .it in motion, thus raising the water'-V .leveL This apparatus operates to maintain the water in the'boiler at or near the same level, for, as the water subsides, the valves are opened, and the pump isldrven faster, to increase the supply, and as the wat-er rises, the valves are correspondingly closed, thus decreasing the velocity ofthe pump, and the quantity of water supplied by it to the boiler.

y Thecock D is used to clear out sediment from the. -water-chamber, or to serve as a pet-cock in adjusting the apparatus to a change of water-level for it. The cock is wholly or partially opened, to regulate the discharge withV reference to the induction-cock 0,' so that the water will pass from the chamber faster than it enters. The result will be that the valves will be opened.-

Having thus described my invention, I claim Aas new, and desire to secure by Letter Patent-V The arrangement of the chambers A B, pipes H J valve-chest I, valves c e, lever b, rod d, having adjustable pin h, lever G, oat F, arm L,aud whistle K, as

herein set forth and shown.
