ALEXANDRE DE BEAUMONT, OF PHILADELPHIA, PA., ASSIGNOR OF ONE- 4 ,HALF HIS RIGHT TO WILLIAM H. PALMER, OF SAME PLACE..

IMPROVEMENT IN HEATER AND FEEDER FOR STEAM-BOILERS.

Specication forming part of Letters Patent No. 187,825, dated February 27, 1877 application filed IIanuary 8, 1877.

To all whom 'itrmay concern:

Be it known that I, ALEXANDRE DEBEAU- MONT, of Philadelphia, Pennsylvania, have invented a new and useful Improvement in Heater and Feeder for Steam-Boiler, of which the following is a specification:

The-main object of my invention is to utilize the whole or-a portion of the exhaust steam of a steam-engine, by forcing it into a-boiler with a supply of water, in the manner described hereafter.

The figure inthe drawing is a vertical section of apparatus for carrying my invention into effect.

A is the cylinder, to Which is adapted a plunger, B, the latter being reciprocated in the present instance lfrom a shaft, D, through the medium of au eccentric, c, and rod b, and the shaft being driven by the en gine.

At the bottom of the cylinder is a tubular i projection, d, the upper end of' which forms the seat for a valve, e, which rises, when the plunger is moved upward, and permits exhaust steam to enter the cylinder from the pipe E, which communicates with the exhaustpipe of a steanrengine.

Water is also admitted in the form of a jet to the cylinder, beneath the plunger. through the pipe F, which communicates with a hydrant or reservoir, a check-valve,'f, in the pipe F, opening on the ascent of the pump-plunger, and closing on its descent.

G is the discharge-pipe, through which and through the chest H, containing a check-valve, the exhaust steam may be forced directly into the boiler.

As the pump operates continuously, however, I nse, in connection With the pipe G, a devicefor automatically regulating the amount of Water which passes into the boiler, so that it will accord with the .requirements of the latter.

'Ihis device 1 will now proceed to describe:

The force-pipe G communicates with the chest I, and the latter, through a pipe, G', with the boiler J. Within this chest is a regulatingvalve, m, which is connected by a rod, lo, to a piston, n, in a cylinder, K, the latter communicating at the top through the pipe L with the steam-space of the boiler, and having a direct communication below at'all times with the outlet-passage q of the chest I, and consequently with the Water-space of the boiler.

The position ofthe piston 'n in the cylinder K is governed by the height of the Water in the boiler, and when the water is at its proper level the lateral openings in the regulatingvalve coincide with openings in that part of the chestin which the valve operates. so that the exhaust steam, combined with water, will pass freely through the chest into the boiler. Should the Water inthe boiler, however, rise above its proper level, the piston n and valve m will also rise and open the lower port w in the chest I, through which port as much of the combined exhaust steam and water will cylinder K, and its float n, carrying a valve,

m, with the chest l, its two sets of ports, and its Waste-pipe Q, as set forth.

In testimony whereof I have signed` my name to this specification in the presence of twosubscribing witnesses.

ALEXANDRE DE BEAUMONT.
