SQ'ECIFICA'ION forming part of Letters Patent No. 303,575, dated August 12, 1884.

Application filed October E9, 1583. (No model.)

To all whom t may concern:

Beit known that I, MATHIAS 'JRGENsnm of Sonoma, county of Sonoma, State of California, have invented an Improved Automatic Boiler-Feed Regulator; and I hereby declare the following to'be a full, clear, and exact dcscription thereof.

My invention relates to automatic devices for regulating the supply of .feed-water to steam-boilers, and it Aembraces certain 4improvements in such class of boiler attachments having for their object to produce a simple and reliable device for automatically turning on a supply of feed-water, as required by the boiler, and shutting ofi' the supply when the desired quantity has been supplied.

The following `description fully explains the natu re of my said improvements and the manner in which I produce, construct, apply, and combine them for the desired purpose, the drawings being referred to by letters and fignres.

Figure l is a general outside view in elevation of a device constructed after my invention. Fig. 2 is a vertical section through the case and fioat. f

A cylindrical case or chamber, A, has connection from the bottom through a pipe, B, with the water-space, and through a pipe, G, at the top, with the steamspace of a boiler, both pipes provided with the necessary valves and cocks x y. Through these connections the same'conditions of steam and water -existrin the cylinder as they do in the boiler, and as the level of the boiler-water is thus always indicated, in the cylinder it is caused to operate agravity-iioat, D-that is, a fioat or drum so ballasted that it is always maintained at a certain depth of immersion, and will fall as well as rise with sufficient force or momentum to operate upon a gear-wheel and impart rotation to a shaft connected therewith. This drum is a weighted cylinder, D, with a tubular shaft or axis, d, extending centrally through it from top to bottom, land carried perpendicularly above the top, also to form a support for or constitute the body of a rack, E. The head of the case A has an extension-chamber, A', upon the top, and in line with this central tube affords room forV the vertical play of the drum, and at one'side -of this space a recess, A2, is fixed to receive a short shaft and a pinion, g.

Athe valve.

Ihe manner in which I connect this shaft.

with the watersupply is as follows: By means of a spur-wheel, J, and pinion K, I connect the shaft g with a counter-shaft, rv', just above it, and to the end of the countershaft I join the stem of a valve in the steam-pipe `of the feed-pump; or, if direct control of a service-pipe is required, the connection will be to the service-cock. In either case rotation of the eountershaft is employed to turn The amount of motion required to open and close the valves determines the proportion and the positions of the wheel and pinion, as will be understood.

To operate a globe-valve, the shaft will require to make several revolutions, and the pinion and spur-wheel will be arranged as shown in the drawings. The float slides upon the fixed guide-rod L, passing through the tubed and secured in the top and bottom ends of the case, and to keep the rack in gear with the pinion a rib or lug, p, on the side of the fioat, takes into a groove, p', in the side of the cylinder. Being thus connected, the float moves up and down as the water-level changes, and between the two extremes of high and low water there is produced sufficient movement of the rack to operate the pinion-shaft with the amount of 93 movement necessary to open and close the valve having connection with the shaft.

In connection with the apparatus thus produced I provide an alarmsignal to indicate automatically any derangement or improper working of the device or its attachments, whereby the supply of feed-water to the boiler is interrupted or is not turned on by the apparatus when required. Upon the steam -pipe O, I place an alarm-whistle, WV, the lever of `which is connected to a chain running over a small sheave, s, on the shaft g, the connection being made by a long link or slotted bar, m., in the chain and a pin in the end of the lever IOO I 5 the alarm-lever.

n, so as to permit the shaft to rotate vunder ordinary conditions without pulling the lever. This attachment is so applied and regulated that if the loat continues to descend in the 5 chamber after reaching the low-water line, at

1o watersupply will be immediately indicated by the alarm-whistle. As no water enters the loat-chamber, the iloat descending below the proper water-linerrwill rotate the shaft sufficiently to wind up the chain and draw down Vherc the same shaft connects with the valve or cock controlling the feed-Water, the valve should have sufficient arca of opening to permit this additional rotation of the shaft to take place without closing 2o or contracting the outlet.

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

l. A feed-water regulator for steam-boilers,

25 consisting of a case or chamber, A, having connection with the water and steam spaces of the boiler through pipes B C, the weighted float, the guides p2, and mechanism connecting said float with a globe-'valve in the steamo pipe ot' the feed-pump in a direct water-sup and applied for operation substantially as hercinbefore described.

2. In a feed-Water regulator, the combination, with a case or chamber having inlets for connection with the water and steam spaces of a steam-boiler, of. the float D, guides 1)?, rack E, pinion g, within the case, and the pinion-shaft Working through the side of the case and having connection with the stem of the valve or service-cock to be operated on,where by the falling and rising movements of the float are caused to open and close the valve or cock, substantially as hereinbeiore described.

3. In a feed-water regulator of the character hereinbefore described, the combination, with the float D, of the rack extending above and from the center of the ioat and the pinion g, within the case, having its shaft projected through a stuihng-box in the side of the pinion-chamber A2.

4L. In a feed-water regulator of the character hcreinbefore described, the combination, with the steam-pipe C, of the alarm-whistle and mechanism, as W, connecting the lever thereof with a shaft, (j, which receives rotation from the rising and falling movement of the float, substantially as hereinbefore de scribed, to operate as and for the purpose set forth.

In witness whereof I hereunto set my hand.
