Description

,initd tair @wat @Wina HENRY I. BRUNNER, OF NZARETEL PENNSYLVANIA.

v Letters .Patent No. 911,515, dated .Tu/ne 22, 1869.

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

To all whom 'it may concern yBeit known,that I, HENRY I. Bauma, of Nazareth, in the count-y of Northamptomand State of Pennsylvania, have invented a new and useful Improvement in Steam-Boiler Feeders; and I do hereby declare that the following is a full, clear, and exact description thereof, whichwill enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

f'lhis invention relates to a new and improved device for supplying steam-boilers with water, whereby many of the uncertainties and dangers ofthe ordinary forcepumps are avoided.

This invention consists in an larrangement for passing the feed-water to the boiler, by means of a transverselyperforated rotating valve, in such a manner that the 'feed-water falls into the boiler by its ,own gravity when `the water in the boiler is low, or when there is a deficiency. When there is a suicient supply of water in the boiler, there is no discharge by the cock, as will be hereinafter more fullydescribed.

The accompanying drawing represents the arrangement attached tothe boiler, partly in section.

A lrepresents the boiler.

B is a chamber in which the valve rotates, and which lorifieethe water is introduced from theV supply-pipe, and then transmitted to the boiler.

As seen in the drawing, it is in communication with the supplypipe, or in a horizontal position. When it assumes a. vertical position in the ycourse of its rotation, the` water it contains is subjected to the boiler-pressure, or to an equal pressurefrom each of the pipes Gand D. The water, being thus balanced in the valve, will fall by its own gravity into the water-pipe D, if the water has fallen below the water-line II, or t there is adeeiency of water in the boiler.

Should there not be a deficiency, or should the water be up to Vthe water-line, there would be no discharge from the valve, as the water it contains would be balanced.

The valve may be rotated by a belt, as indicated in red color in the drawing, or by gearing, or be actuated in any convenient and suitable manner.

I isa stop-cock in the supply-pipe F.

J andK are stop-cocks in the pipes O and D.

L is a small cock in the supply-pipe for letting oft' air, When starting the valve.

It will thus be seen that the boiler is supplied with a constant and uniform quantity of water, without forcing the water against the boileras it is where a force-pump is used; and that the pressure on the valve being balanced, the valve will rotate without any injurious amount of friction.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent- The arrangement of the transversely-perforated valve E, in relation to the supply-pipe F aud pipes O and D, respectively communicating with the steam and water-spaces of the boiler A, substantially as HENRY I. BRUNNER.
