NIED STATES JAMES \V. l-IAWORTH, OF
KANSAS CITY, MISSOURI.
REFLECTOR FOR BOILERS OR EVAPORATORS.
SPECIFICATION forming part of Letters Patent No. 684,818, dated October 22, 1901.
Application filed February 11, 1901. Serial No. 46,957. (No model.)
To (0% whom 231 may concern: I
' Be it known that 1, JAMES W. HAwoRTH, a citizen of the United States, and a resident of Kansas City, in the county of Jackson and State of Missouri, have invented new and useful Improvements in Reflectors for Boilers or Evaporators, of which the following is a specification.
My in vention relates to means to be applied to boilers or evaporators for absorbing from the fire a large portion of the heat which would otherwise be wasted through the stack or chimney and for giving back the heat so absorbed into the combustion-chamber below the boiler or evaporator, thereby maintaining the temperature of the contents of the boiler or evaporator for'some time after the fire is drawn or dies down.
The object of my invention is simply to economize the heat from the fuel, and to this end I cover the brickwork below the combustion-chamber with a thick coating of fire-clay and fill in the space below said brickwork with a bed of cinders. In construction the bed of cinders is first placed between the boilerwalls and tamped solid, and then the brick are laid above the cinders in the manner more fully described hereinafter.
In describing my invention reference is had to the accompanying drawings, in which- Figure 1 is a side elevation, partly in section, of my invention as applied to a boiler, the nearest side wall being broken away and the brickwork above the boiler omitted. Fig. 2 is a transverse sectional view taken on line a b of Fig. 1, except that the boiler is not in section. Fig. 3 is a detail view showing a special form of heat-absorbing tile to be Fig. 4 is a longitudinal vertical sectional view of my invention as applied, to a fiat evaporatingpan. Fig. 5 is a transverse sectional view taken on line 0 c of Fig. 4.
In Figs. 1 and 2, 1 designates a cylindrical boiler supported by hangers resting on. side walls 3. 4 designates the back wall. On the floor of the boiler-room or in a pit sunk below the floor I lay a bed of screened cinders 5 between the side walls 3 and back wall 4. The cinders are tamped rather solid and are filled up to a suitable height, and on top of the cinders I lay one or more courses of brick 6, preferably as shown in Fig. 2; but the arrangement of the individual bricks may be varied, as the object is only to form a layer of brick over the cinders and to conform tho upper surface of the brick to the arc of a circle somewhat larger than that of the boiler. The bricks are preferably built somewhat closer to the sides of the boiler than to its bottom, as shown in Fig. 2, though this is not essential. A coating of fire-clay 7 is then applied to the exposed surface of the bricks, as shown in Figs. 1 and 2. The thickness of this coating may be from one to twelve inches. The purpose of the fire-clay is to provide a smooth heat reflecting surface under the boiler.
Instead of employing ordinary brick I may employ curved segmental tiles 8, such as are shown in Fig. 3. These pieces may be made of cast-iron; but baked fire-clay is the preferred material. The advantage of this form of tile is that they may be more quickly laid and removed than ordinary brick when used in connection with boilers which have to be moved from place to place. In Fig. 3, 8' designates the layer of fire-clay above and between the tiles.
My invention is applicable to the evaporating-pans used in the manufacture of certain syrups, these pans usually being large and shallow. In Figs. 4 and 5, 9 designates such a pan supported by side walls 10. 12 designates a grate, and 13 a bridge-wall extending from one of said side walls to the other. Between the side walls and the back wall I lay a thick bed of screened cinders 14, and above this I lay one or more courses of brick 15, entirely covering the cinders. The brick 15 are covered with a layer of fire-clay 16. The brickwork should be inclined from the horizontal, as shown in Fig. 4, being nearer the pan 9 at its rear end in order that the cooler part of the fire or products of combustion may be closer to the pan than the hotter portion next the fire. The arrows indicate the direction of the products of com bustion. 17 designates the lower portion of the stack, and 18 is the usual pit or chamber below the stack.
The operation of my invention is simply that the fire-clay, brick, and cinders absorb heat from the fire and become a heat-reservoir, and when the fire gets low from any cause this heat is radiated into the combustion-chamber and is mostly communicated to the boiler or evaporating-pan. The fire-clay further acts as a reflector for directing heat into the boiler or evaporating-pan. This is a smoke-consumer as well as a fuel-saver.
Having now fully described myinvention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
The combination with a cylindrical boiler and side walls supporting the boiler, of a mass of cinders between said walls, below the JAMES V. HAWORTII.
