MAGAZINE IN BASE-BURNING' STQVES.,

The Schedule rfened to in these Letters Patent and maldng part of 'the sama.'

To all lwhom tt may concern v Be it known lthat we, JASPER VAN WoRuER and MICHAEL MCGARVEY, both of the city-o);` Albany, in the county of Albany, and Statepf New York, have invented a new and useful Improvement in Magazines for Self-Feedin g Stoves and we do hereby declare that the following is a full. and exact description thereof, ref? erence'being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a sectional view of a complete stove having our improved magazine or feeder, f

Figure `2 is a perspective view of the magazine or feeder.

Figure 3 shows our method of hanging the feeder in thel steve, so that it may be adjusted to regulate the discharge of the coal.

Figure i represents our 'method of connecting the twokparts of the feeder, t'. c., the vreservoir and the nec Like letters refer to like parts.

A. is the coal-reservoir, having its lower part, C, contracted.

B is the neck, having a flaring mouth-piece, D, attaehed to its upper end.

E E are pins, attached to the outside ofthe flaring mouth-piece D.

F E are notches in the lower edge of the contracted end, C, of the reservoir.

I, iig. 4f, is the portion of this lower edge between :the notches, cut on an incline.

'Ihe dotted line H H, iig. 4, is the upper edge of the flaring mouth-piece D, as it rests on the inside of the contracted end, C.

In self-ieedin g or magazine-stoves, as heretofore constructed, there have been found several seriousiobje'ctions, arising from the peculiar construction of the reservoir.

When the reservoir has been made of the same size throughout its entire length, or where there has been a slight gradual increase in size towards the lower end, it is found that the coal in the reservoir presses down on the burning mass of coal underneath with too great weight.

- When the reservoir is constructed with a contracted discharge-end, the coal is continually choking and clogging up at the outlet, so that its descent is not free, often clogging during the night, causing the fire to go out for the want of a supply of fuel. The most tangible reason for this obstruction is that the heat enters the coal at the lower end of the reservoir, where it lies immediately over the burning mass in the iire-pot causing the coal to become expanded, and bind itself fast, forming an arch, so that a poker or iron bar has to be used to force it down into the lire-pct.

l To obviate and overcome these difculties, we construct a magazine or feeder as follows:

The upper portion A consists of a reservoir, made large, so as to hold a large body of coal, and having its lower portion contracted, as shown in the drawings.

Attached lto this reservoir, and forming the lower part of the yfeeder, is a neck, B, of sufficient length that the reservoir, with the body of coal in reserve, shall be placed at such a' distance from theburning coal as to b'e out of the intense heat. This neck is enlarged at its lower end, giving a free discharge of the coal, with no risk of clogging or choking. The

enlarging of the neck at its lower end will completely mouth-piece, formed at an angle to correspond with that of the contracted part of the reservoir. The diameter of the upper part of the mouth-piece must begreater than that of the lower edge of thecontracted end of the reservoir, so that, while the ,mouth-piece will iit down into this contracted end, it will not slip entirely through it, but will be supported by it. In the lower edge of the contracted end of the reservoir are cut three notches, of the same size, and at a uniform distance apart. Three pins are attached tothe outside of the aring mouth-piece ofthe neck, so as to correspond. with these notches, and to allow of their passing down through the notches. The lower edge of the contracted end of the reservoir, between each of these notches, is cut on 'an incline, so that, when the neck has been passed down through the reservoir, the pins passing through the notches, the daring mouthpiece of the neck resting upon the inside of the contracted end of the reservoir, by a slight turn of the neck, the pins pass under the inclined edge, and lock the neck and reservoir firmly together.

What we claim as our invention, and desire to secure by Letters Patent, is-

1. Attaching to the ordinary contracted reservoir a neck, having its lower end enlarged, substantially as and for the purpose described.

2. The method of attaching the neck to the reservoir, :substantially as set fort JASPER VAN WORMER.
