IMPROVED BOITIER-FEEDER.

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

the d rum, where it would remain until the water in the vboiler' shall have fallen below the mouth of the pipe D, when steam will again flow into the vessel, and the water will pass into the boiler.

When the device is operating regularly to feed the boiler, and a suicieut quantity of water has passed out of the drum A, to enable the weight O to raise it, the lower valve-seat is brought iu contact with the lower valve, and thecommunication between the boiler and the vessel A is cut off. At the same time the upper valve is carried away from its seat, thus permittingrwater to flow into this vessel through the apertures e', and refill the same, when it will beiy again carried down, and the communication with the boiler Y established', and thus the operation will be repeated so long as is desired.

The diaphragm N is to prevent leak and friction, which are two very lmportaut items in automatic feeders, for the following reasons, viz: Suppose the height of the feeder gives a gravity of ve pounds to the square inch on the boiler, and the running pressure of To all whom it may concern Be it known that I, SAMUEL J. PARKER, of the city of Williamsport, in the county of Lycoming and the State of Pennsylvania, have invented certain new and useful Improvements in Boiler-Feedersyand I do hereby declare that the following is a full and exact description thereof.

a pipe otherwise supplied, under slight pressure, and which is transmitted to the boiler at intervals through an intermediate vessel, which is alternatelyglled with water and steam, as hereinafter will be more perfectly described.

The accompanying drawing forms-a part of this specification, and like letters denote like parts. Figure 1 is an elevation of my improved apparatus; and

Figure 2 is a vertical section, with the4 chamber in its lowest position, so that it receives steam from the boiler in its upper portion, and discharges water into the boiler from its lower part.

The red dotted lines show the chamber in its most elevated position.

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

A is a 'strong drum or movable vessel hung under the frame B, and sustained by a counter-balance lever, C.

D is a small pipe from the water line of a steamboiler, terminating-in the drum at the valve-seat E, which must not be over one-fourth the area of the valve-seat E, or the said drum would come to a balance. The flanges E' E" on the valve are necessary, not only to catch the current of steam, to react the drum and close the valve, but they make a larger chamber, to allow the steam or water, as the case may be, to circulate through the holes e.

The pin K is stationary with the frame B.

The drum A must be of suiiicient capacity to hold more than enough water to balance the weightO, and

pounds out to one pound in, the smallest leak will make a greater current out than into the boiler, and y empty rather than feed it.

A small amount of friction, when soft water is used, `is not very disadvantageous, but when hard water is used, considerable caution and watching is wanted to keep the feeder in operation.

In my feeder it will be seen that no friction or pack- -ing is used, and that n o leak can occur in a perfect apparatus.

Having fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is

,1. The combination ofthe vessels A G and the movable valve-seats E, substantially as -shown and described.

2. The combination of the stationary valve I and movable valve-seats, the'connecting-ppe, with the diaphragm N upon its upper'end, and the weighted lever C, substantially as described.

3. The arrangement of the pin K for holding the on the boiler.
