UNITED STATES PATENT OFFICE.
ROBERT E. VARDEN, OF UNIONTOWN, MARYLAND.
COAL-STOVE.
Specification forming part of Letters Patent No. 91,186, dated June 8, 1869.
Be it known that I, ROBERT B. VARDEN, of Uniontown, in the county of Carroll and State of Maryland, have invented certain new and useful Devices in the Construction of Hot-Air Stoves; and I hereby declare the following to be a full and sufiicient description thereof, reference being had to the accompanying drawings and references, which make part of the specification.
The figure in the drawing represents a vertical elevation of the stove, portions of the front and rear outside plates being removed to show the construction within. Besides these loose outside plates (not seen in the drawings) the front plate, being a part of the fixed cylinder and represented by y y, is removed to show the cylindrical fire-box A below and the hot-air cylinder B above it. Besides this the cylindrical covering of B is also removed on its front side to show the zigzag currents of heated air, which are heated first in the fire-box A, and lastly in the zigzag passages in the hot-air cylinder B.
' The nature of the invention consists in the construction of a compound air-heater, the principal feature of which is in placing the airheater B directly over the middle part of the fire, so that the flame and products of combustion will ascend from the fire-box A on the inside and on the outside of cylinder B, and hence the air must receive heat from two surfaces of meta-l instead of one, as is the case with other hot-air furnaces.
A is a short hollow cylinder, of cast-iron, set in the base of the stove, with a suitable firegrate under it. The grate and the inner periphery of A constitute the fire-box, and is at least a third larger than cylinder B, which is above it. Cylinder B is of the same form as A, but is a third smaller, and twice as high as A. The center of cylinder B is directly over the center of A. The internal part of A is unobstructed with any thing to impede the current of air passing through it. It has a door in front, b, and a discharge opening behind from its top, (not shown in the drawings,) but is of the same form as (H, and leading from the upper part of fire-box A to the lower part of hot-air cylinder B in the rear. CylinderB has its covering removed in front, as shown at w x, to expose the zigzag direction of the currents of hot air passing around it, as indicated by the red arrows.
The air of the room enters the lower part of cylinder A at b, and divides, as seen by the red arrows, one portion going to the right and the other to the left. They meet in the rear and ascend through a pipe, (not seen in the drawing, except by its position at dotted lines 0b,) and enter the hot-air space .in cylinder B and pass in zigzag current, as shown in the drawing, entirely around it, escape through the exitpipe a at the top, and are discharged at a into the hot-air chamber above the stove. (Not shown in the drawing.)
The fire having been lighted in the fire-box A, the flame and products of combustion ascend over the inner and outer surface of the hot-air cylinder B, and, passing upward, escape through the smoke-pipe 2 and down through pipe 1, and so descend to the bottom of the stove through drawer c, thence under the ashdrawer D and drawer c, and out through pipe 4 into the chimney, as indicated by the red arrows.
The short pipe 3 is kept closed by a damper while the stove is in operation; but while kindling the fire it is left open to allow of the direct escape of the smoke.
Immediately under the vertical smoke-pipes 1 and 4 are the drawers 0 0, having the inner side of each hinged to drop down on the bottom, where they rest during the time that the stove is in operation, for the purpose of controlling the draft of the fire on the one hand, and receiving the soot and dirt from the smokepipes on the other.
Drawer D, under the center of the stove, is for receiving the ashes falling from the grate and allowing air-passage for feeding combus' tion.
The advantage of this air heating stove over other hot-air stoves is that the air-heater B is heated both on the inner and outer surfaces at the same time, while other hot-air stoves are heated from only one fire-surface.
The novelty of the drawers 0' is that they perform the double function of being a soot-receptacle and controlling the draft at the same time.
Having stated the nature of the invention periphery, substantially in the manner and and the mode of using the same, what I claim for the purpose set forth. as my invention, and desire to secure by Let- 2. Also, the arrangement and construction ters Patent, isof drawers 0' c, as described.
1. The arrangement and construction of the air-heating chambers in such manner that E while A acts as a fire-box and air-heater, B Witnesses: shall be enveloped by flame and products of J. R. NOTTINGHAM, combustion through its axis and on its outer L. D. GALE.
