NATHAN PUGKETT, or DEMING, INDIANAQ e BOILER-FEEDIN Specification of Letters Patent No.

To all 'whom it may concern: t

' Be it known that I, NATHAN PUGKETT, of Deming, in the county of Hamilton, and State of Indiana, have invented a new and useful Improvement in Boiler-Feeders; and Ido hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making part of this specification.

Figure l, is a vertical transverse section through a steam boiler, with theimproved feeder attached to its side. Fig. 2, is a vertical longitudinal section through the `feeder at the dotted line l, 2, ofFignl. i

Similar letters in the figures refer to corresponding parts. t

To enable others skilled in the art to make and use my invention I willproceed to describe its construction and operation.

The valve chest A, is made of a rectangular form open above and below, with a recess A', formed in the surface against which the face of the valve bears, for increasing the quantity of water conveyed by it. Near the upper end of this chest, and on theground interior valve surface, `is made an1 oblong opening B, which is situated a short disand communicates through a feed pipe with any suitable formed heater arranged at the proper elevation to causethe water from it to fill the chalnber of the valve. Another oblong opening C, corresponding with the opening B, is made near the lower end of the valve chest, which opening communicates with the boiler a short distance above the low water line, and this opening C, and the before mentioned feed opening B, are made to alternately communicate `with a chamber or space D, formed in the face of the valve E, which chamber or space communicates with the space or recess A, at all times, but with only one of the openings B, l C, at a time, on account of the difference in the height of the chamber D, with the distance apart of said openings B, C. l

The valveV E, receives its up and down motion by means of a cam or protuberance F, on the periphery of a hub secured` on a horizontal revolving shaft Gr, `turning in suitable boxes secured to the top of the valve chest, which cam or protuberance F, is caused to alternately operate during its G ArPAaATUs. y
