WIIJLIAM MOORE, OF KOKOMO, INDIANA.

IIVPROVEIVIiENT IN AUTOMTIC BO'lLER-FEEDERS.

To all whom t 'may concern:

Be it known that I, WM. MOORE, ofl Kokomo, in the county of Howard and State of Indiana, have invented a new and useful lmprovement in Automatic Steam-Boiler Feeders; and I do hereby declare the following is a full, clear, and exact description of the same, reference bein ghad to the accompanying drawings, and to the letters of reference marked thereon, and which make part of this specifi! cation. n

Like letters in each of the 'figures denote the same parts.

Figure 1 is a top view. Fig. 2 is a front view. Fig. 3 is a section,showing supply and waste pipes, also how the partition may be made movable, 85e.

The object. of my invention is to supply a sufficient quantity of water to the boiler at all times, as well as to indicate the quantity in the boiler, thereby aifordin g a sure precaution against the losses and danger to life Iconsequent upon explosion of steam-boilers, especially those used in saw-mills and for similar purposes.

Ihe nature of my invention consists in attaching a swinging nozzle to the supply-pipe, and regulating the saine by means of a oat and levers, which are so arranged that when the water is lower in the boiler a greaterquantity will be supplied by the nozzle being brought more l,directly over the mouth ofthe pipe which supplies water to the heating-chest, and which chest is connected directly to the force-pump which supplies the boiler. As the water is higher in the boiler a less quantity will be supplied, in consequence of said nozzle receding or coming more directly over the waste-pipe, the wastepipe and supply-pipe being separated at top only by the thickness of a piece of tin.

`To enable others skilled in the art to make and use this feeder, I will proceed to describe the same by means of the drawings.

A is a boiler of any ordinary construction, perforated in either end (or in the side, if desirable) by a hole of suitable dimensions, into which I insert the shaft M, Fig. l, which is rendered steam-tight by means of a stufiingbox. On the inner end of said shaft is attached the tloat X, Fig. 2, having a suitable lever to cause it to rise and fall with the surface of the Water in the boiler. Said shaftY extends out from the boiler over the support It, which has a partial iiange on the upper side, against which the outer end ofthe shaft Works on a pivot at L, Fig. 2.

J is a lever attached to the shaft for the purpose of balancing the float X. T is a cam working against a spring', (or the same effect may be produced by the usual leverand-joint arrangement,) which gives an alarm by means of the Whistle S when from any cause the force-pump has failed to supply a sufticiency of water to the boiler. U is au arm connected to another arm, YV, by means of a togglejoint. The arm U is connected yto the shaft It by a fixed joint. The arm W is connected to the swinging' nozzle a, and by the rising and falling of the iioat X it will be readily seen the nozzle Will be regulated over the supplypipe Gr or waste-pipe E as a greater or less quantity of water is needed, and so accurately may it be'graduated that it is impossible for the water to vary so as to cause any danger of explosion or any perceptible irregularity in the generation of steam.

It, Fig. l, is the force-pump, with its pipes for receiving and discharging water. I is a hot-water chest, which is heated by wastesteam, to which is attached a waste-Water pipe, P, and a wastesteam pipe, E.

I would here state that instead of the swinging nozzle an indiawrubber tube may be used, or the tube V may be Xed or stationary7 and the supply and waste pipes may be hung or iiXed to move to and fro under said tube; or in some cases it might be more convenient to have all three of the tubes fixed and the partition movable, so as to direct the water into the supply or waste pipe, as necessity required.

The principal difficulty I aim to overcome is that experienced in the use of automatic stop-cocks and other means heretofore in use in supplying water t6 steam-boilers, by which the supply becomes irregular and sometimes ceasing entirely in consequence of the parts becoming iilled up by sediment or by the stopcocks becoming inoperativeA by corrosion and other causes. In my invention these difficulties are meant to be overcome, for however muddy the Water it has a free passage from the size of the tube used, and its ceasing to flow is readily discernible at all times.

Another advantage of my automatic boi1er feeder consists in the manner of arranging the shaft so as to overcome a great amount of y friction, and at the same time attaching a Whistle, so as to give an alarm if from any cause the water should becomelow in the boiler.

In my arrangement the only friction to overcome is that in the stuffing-box and at the pivot, both of which can be easily lubricated. The float being thus rendered very reliable,

the whistle can therefore be depended upon,

1. The swinging nozzle or its equivalent, y

constructed and arranged substantially as described.

2. The combination of the swinging nozzle with the shaft B, arranged Vin the support R,

with the pivot L, substantially as described,`

and for the purpose set forth.

3. The combination and arrangement of the nozzle a, shaftB, and Whistle S, all constructed and arranged as and for the purposes set forth.

In testimony whereof l have signed my name to this specification. l l WILLlAM MOORE. Witnesses:

H. GARRETT, I. F. WILDMAN.
