fltnttml time HENRY E..S,'I AGE R, OF MILWAUKEE', WISCONSIN Letters Patent No. 93,564, dated August l0, 1869, antedated July 31, 1869.

IMPR'ovEMEiv-r IN AUroMA'x-Ic Bomen-Femmes.

The Schedule referred to :in these Letters Patent and making part of the same.

To 'all whom it 'may concern Be it known that I, HENRY E. STAGER, of the city and county of Milwaukee, and State of Wisconsin, l1ave.'invented a new and useful Improvement in SteamBoiler Feed-lVater Regulator; and I do hereby declare that the following is a full, clear, and exact description thereof, which will 'enable those skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification, in which- Figure 1 is a perspective view.

Figure 2, a sectional view.-

Similar letters l of reference in each of the figures .indicate corresponding parts.

The object of my invention is to regulate the flow of .water into a steam-boiler, so that-the water may be kept at a uniform height, no matter how much steam may be used;

A is the top, or crown-sheet.

B, the bot-tom. f

C, lever.

l), weight on the lever O.

E, standard, resting bn a cross-bar forming a fulcrum for lever C.y

F, pipe connected ywith'the upper part of the regulator, and with the boiler below the water-line.

G, pipe connecting the lower part of the regulator with the boiler, either above or below the water-line, according to the height of water in the boiler. This pipe is made in V-shape, or in the shape of a siphon,

and is to have its end in-'the boiler, at the point Where "it is desired to have the water-surface the highest.

H, valve. Thisvalvehas an upperand lower plate, with a space. between, exceptwhere connected in the centre.

I, a ring, forming a circular wall for the chamber,

Ii, centre-pin of the valve.

`L, a round sheet of rubber packing, forming a diaphragm, lfastenedto valve H by the centre-pin K, projecting through and headed down. This rubber diaphragm is large enough to lill the space out'under ring I, and under this rubber, and under ring I, is a metal ring, made fiat, just as wideas the thickness of ring I, fitting into a recess turned in the bottom B.

M is a rubber diaphragm, on the, top of valve'H, secured and fitting in a recess over ring I, with a metal ring in -same manner, a s heet, L, at the bot-d tom, the upper and under pieces A and B 'secured firmly on to the ring I by the bolts shown in iig. 1, making a perfect steam-joint both at the top 'and bot-Y tom of ring I.

N is the opening in pipe F. i

O is the opening in pipe G, -both communicating with the boiler.

P, water-space under valve H. Q, water-space over valve H. Valve H is connected tothe case of' the regulator by the rubber sheet L and M, the elasticity of which will .permit valve H to rise and fallas it may be acted on, and thus raise or lower the weighted end of lever C.

Ris a pivot or pin in one side of valve H, there being a corresponding oneon the opposite side, passing through openings in ring I, large enough to permit them to rise and fallsuicient for the object tobe obtained. t y

To these pins is a standard, 011 which isv secured the .cross-bar on which rests the fulcrum E, forming a yoke.

Operation. v The regulator is first connected with ,the boiler by pipe F, at a point always below the water-line in the boiler, and by pipe G with its end, just at the point in the boiler where itis intended to have the waterline when the water is at the highest point. l

Vfor an overliow, which returns the water to the reservoir from which it is taken; and this action is accomplished in this'way:

When the water in the boiler is below' the end of pipe G, that pipe is illed with steam in that leg `connected with the boiler, and the pressure on the under side of valve H is greater than the pressure on the l `upper side, and the valve is raised, and with it lever C,- by means of fulorum E, resting on the yoke coni nected with the valve bythe stems R, and the cock 'cpmniunicating with the boiler from the water-reser-A voir is open, and the water flows into the boiler, or is forced in by the feed-pump.

As soon as the water in the boiler rises above the end `of .pipe G, the steam in the pipe is condensed, and watertakesdts place, and, as water is heavier than steam, the pressure is taken o ifthe lower side of valve H to the extent of the difference for the whole water-surface.

The pressure on the upper side being continuous, the valve falls, lever O is depressed, and the watercommunication. with the boleris closed.

When the water in the boiler falls below the end of pipe G, the water is emptied tothe-summit of that leg, and steam takes its place, and thepressure is increased on the bottom of valve H, and water is again communicated to the boiler, and thus the water is kept at or near a uniform height.

VVhab I claim as my invention, and desire to secure by Letters Patent, is A 1. Valve H, diaphragme L and M, amd.V ring I, :1.1;- ranged substantially as described.

2. The arrangement of the valve H"Wil,l1 the yoke, resting on stem R, fnlcrnm E, and lever @,snbstantially as described.

3. Pipes F and G, in combination with valve H, sheets A and B, and ring I, whereby to increase and diminish pressure by alternations of steam and water,

substantially as described.
