IMPROVEMENT IN AUTOMATIC BIOILER-FEEDERS.

running by gravity past a check-valve. 4From the feed-vessel two pipes lead to the boiler, one going to the lower part, and provided with a checkvalve, and the other to the steam-space of the boiler, either at or above the water-line, and to this steam-pipe a valve y is applied, controlled by the expansion of alcohol or other material, or its vaporization in a vessel that is periodically exposed to the action of steam; The expansion closes the steam-valve, and, as the apparatus cools, the steam condenses, the pressure lessens, the feed-water runs in, and, cooling off the apparatas, lessens the pressure of the alcohol in the expansion-vessel, and the steam-valve is opened by a weight, the pressure equalizes in the feeder and boiler, and the water runs into the boiler by its hydrostatic pressure, and the steam reaches the expansion-vessel, heats the same, and the operations are repeated. y
An apparatus has been made for feeding water to a boiler, in which the expansion or vaporization of alcohol or similar material, has been availed of to turn cocks inthe steam and water pipes; but these are liable to be partially turned and allow steam or hotwater to blow through the supply water-pipe.
By using valves in the supply and water pipes, leading to and from the feed-vessel, these become self-acting, and the steam-valve,
opening against the steam pressure, will move suddenly, hwhen the weight is unsupported, and opening fully admits steam into the feedervessel ,"hence the apparatus will always be in a fully-operative condition. W
f In the drawing I have represented this improvement by a vertical section of the apparatus.
The vessel a is provided with a pipe, b, and
check-valve c leading to a reservoir, or other water-supply. The check-valve e is in the pipe d, that passes to the water-space of the steam-boi1er,or to a steam-generator for heating apparatus. The valve fis in the coupling that connects the steam-pipe g to the vessel a, and this valve is opened against the steam pressure by the lever h and weight k.
The expansion-vessel l is preferably made of .a copper case, m, and diaphragm n, above which is the press-bar o, that connects with the lever h.
The alcohol, or other expansive or volatile material contained in the vessel l, expands and, raising the lever h, closes the valve f, whenever the steam heat, reaching such vessel l through the tube r to the containingcase s, is suliioient to generate the required pressure.
It will now be understood that when the vessel l is cool the valve fis open, and steam passes in from the boiler to the vessel a, and, closing the valve c, shuts off the inlet of' water, and whenever the pressure of steam in a corresponds to that in the boiler the water will run from this feed-vessel a into the boiler by gravity, and the steam reaching the lower end of the pipe r will take the 4place of the water therein, and pass to and heat the expansion vessel l, and close the valve f. The valve e will close by the pressure from the boiler, and both e and f will remain closed until the pressure in a decreases, the fedl water runs into the vessel a, and the expansion# vessel l' is cooled and contracted sufficiently to allow the weight k to open the valve f, and the operations are repeated.
When the steam-pipe g is connected to the boiler, at ornear the standard water-line, the vessel a will not become4 empty until the water-line descends so asto allow steam to take the place of the water; but there may be a circulation of the water through this'vessel a if the same is entirely filled, but that will not heat the expansion-vessel l; hence the valves f and c will remain open.
