RALPH GREENVOOD, OF AIIOONA,.PENNSYLVANIA IMPROVEMENT IN FIRE-.BOXES FOR LOCOIVIOTIVE-ENGINES.
Specication forming part of Letters Patent No. 25,009, dated August 9, 1859.
To all whom it may concern.-
Beit known that I, RALPH GREENWOOD, of Altoona, in the county of Blair and State of Pennsylvania,`have invented a new and useful Improvement in Fire-Boxes for Steam- Boilers; and I do hereby declare that the following is a full, clear7 and exact description of the same, reference being had to the annexed drawings, marking a part of this specification, in which- Figure l is a side view of a locomotive iirebox. Fig. 2 is a front sectional view of the same, taken in the line t x, Fig. 3. Fig. 3 is a side sectional view ot the same, taken in the line y y, Fig. 2.
Similar letters of reference indicate corresponding parts in the several figures.
This invention, although applicable to all steam-boilers, is more especially designed for coal-burning locomotives.
The obj ect of this invention is to consume the inflammable products of imperfect combustion and at the same time present to the direct action of the tire.a larger area of heating-surface, thereby economizing in fuel and augmenting generally the efficiency of coalburning locomotives.
The invention consists in the employment or use of a mid-feather or water-chamber placed directly over the iire and provided with a plurality of small tlues, which form a communication between the fire-box and a gaschamber above, into which, as well as into the fire-box below, air is admitted through hollow stay-bolts at the sides and end of the boiler and the desired object attained.
To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.
A represents the iire-box ot a locomotive provided with double walls, which form water-spaces a, communicating with the boiler B.
C is a mid-feather or water-chamber, which is placed within the fire-box directly over the tire. This mid-feather extends the whole width and length of the iire-box and forms a 'partition or barrier between the tire-box and what may be termed a gas-chamber, D, which communicates with nue-tubes Z). The water-chamber C communicates at its front end with the boiler B by a vertical tube, cand said water-chamber is provided with hol,
low stay-bolts d, by which a communication is formed between the fire-box and the gaschamber, as shown clearly in Figs. 2 and This mid-feather or water-chamber C maybe constructed of boiler-plate and arranged precisely similar to the double-walled waterspaces d of the fire-box; or perforated iirebricks may be used with advantage, although the water-chamber would be preferable, on account of its economy in increasing the heating-surface of the boiler.
The gas-chamber D is made to communicate with the` external air at one or both sides by means of perforations c, formed by hollow stay-bolts, the outer oriiices of which are provided with a register, E. The fire-box A, also, is made to communicate at each side with the external air by means of hollow stay-bolts f, the outer orifices of which are also provided with a register, F. The two registers E F at each side of the tire-box are connected by a lever, G, as shown clearly in Figs. l and 2.
The water-spaces d at the front end of the tire-box and gas-chamber are also provided with hollow stay-bolts g to admit air to the tire-box and gas-chamber, and the fire-box is also provided with hollow stay-bolts 71 at its back end.
By having the registers E F connected by the lever G, as shown, the openings c fof the gas-chamber and tire-box may be contracted or enlarged simultaneously, according' to thc amount of oxygen required.
The operation is as follows: The draft from the tire being through the hollow stay-bolts d of the mid-feather or water-chamber (l, the products of combustion, or, rather, the products of imperfect combustion, are divided, so as to readily combine with the oxygen admitted into the gas-chamber D, and the temperature of the gases, when combined with oxygen, will be sufficiently high to cause them to Aignite and be consumed. Oxygen is also admitted into the fire-box through the hollow stay-bolts g 7L f, so as to produce a perfect and even distribution of draft through the midfeather or water-chamber and a more perfect union of the gases and oxygen.
I am aware that a mid-feather has been used in connection with an air-chamber as a means for distributing air into the iire-box, and I do not claim such device when placed in relation with an air-Chamber fors'uoh purpose; but I am not aware that a mid-feather has been used singl)7 and simply as a distributer to divide or spread the inflammable products of imperfect combustion and render their union with the oxygen admitted into the chamber more perfect than it would otherwise be.
I claim therefore as new and desire to secure by Letters Petent- 1. The mid-feather C, when used in eouneetion with a gas-chamber D, and lfire-box A,
provided with openings e f g 7L, the parts being arranged relatively With each other to operate substantially as and for the purpose set forth.
2. The two registers E F, when applied to the orices of the gas-Chamber and lire-box and connected bya lever, G, to operate simultaneously, as and for the purpose set forth.
RALPH GREENVOOD.
