DAVID C. VALTER, OF TOLEDO, OHIO.

FEED-WATERA REGULATOR.

SPECIFICATION forming part of Letters Patent N0. 294,705, dated March 4,1884.

Application filed April 2T, 1883.

To all whom, t may. concern,.- l

Be it known that I, DAvID C. VALTER, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented a new and useful Feed-Water Regulator for Steam-Boilers, of which the following is a specification.

My invention relates to improvements in feedwater regulators for steam-boilers, in which is placed, in close proximity to theboiler, an upright cylindrical chamber containing a float operating a valve delivering steam to a positive-acting steam feed-pump; and the objects of my improvements are, first, to keep water in the boiler'to its proper height; second, to provide means whereby steam `is delivered to the steam feed-pump direct from the boiler, the object being to avoid creating a reduction of pressure in the float-chamber, which causes the water in said chamber to rise vabove the'water in the boiler, thereby closing the valve before the proper time; third, of, an overfio f-pipe placed just above the water-line. In case the water rises in the chamber above the proper height it will flow through said pipe back into the boiler, thus preventing the, float from rising too high. I attain these objects by the mechanism illustrated in the accompanying drawings, l in which;

Figure l is a side view of my improvement attached to a boiler. In this view a portion of the chamber is broken away, showing thelocation of the valve-arm and its c onnectingrods.

Similar letters refer to similar parts throughout the several views.

In Fig. l, A is an upright cylindrical chamber containing a float, h, (cylindrical in form,)

the chamber A communicating with the steam nected to the float h in said chamber by the valve-arm f and connecting-rod g. The'float is weighted at the lower end with heavy suitable materialfto keep it in a vertical position and give it weight sufficient to move the valve.

Fig. 2 is a detailed view of the chamber, ioat and valve, and balance-rod and ball.

(No model.)

steam-tight wall between the valve and float chamber, thus preventing the escape of steam from said chamber, the obj ect being to prevent any reduction of pressure in the float-cham ber.

In Fig. 2 the Valve-shaft m extends through the casing of the float-chamber, the fioatbeing connected to the shaft m in the manner shown at a" by the valve-arm f and connecting-rod g.

e2 is a portion of the valve-chamber extending from and into the chamber leading to the cylindrical Heat-chamber. The opposite end of the valve-shaft extends through a metallic stuffing-box, J, which, beingscrewed in against a shoulder on the valve-shaft, forms a steamtight joint, and also takes up lthe wear of the valve. T K

b3 is a knob secured to the outer end of the shaft m. Y

O is a balance-rod passed through an opening in said knob at right angles to the shaft m.

P is a weight secured to one end of the rod O. By shifting this rod from one side to another the valve may be regulated without reference to the float.

Z is a steam-whistle placed above the upper wing of the valve.

In case the water in the boiler gets too low the upper wing of the valve passes the port, giving steamto the whistle, thus giving low- Vwater alarm. The reverse of this movement gives alarm for too much water..

The pipe-o1J is situated just above the water- Y line, between the iloat-chamber and boiler, and

in case of any reduction of pressure in the chamber the water will iiow back into the boiler and prevent the iioat from rising.

In a `boiler-feeder substantially as described and shown, the combination ofthe boiler, the float-chamber arranged alongside of and connected with the boiler by steam and water I OO pipes, the neat, the valve-chamber connected j by suitable pipes with pumping-engine and tween the valve and Hout chamber, whereby IO supported on and opening,` into the ont-ehmnthesteain is passed direct from theboiler to the ber, the steam-pipe connecting the boiler and pumping engine, substantially :is described, the YulYe-ehmnber, and the rotary valve Con- :ind i'or iliepurposes specified.
