IMPROVEMENT lN BRICK-DRYING HOUSES.

Specification forming part of Letters Patent No. 125,013, dated March 26, 1872.

I, GEORGE G. BOVEY, of Cincinnati, Hamilton county, Ohio, have invented an Improved Drying House, of which the following is a specification This invention relates to a house which has been designed for the purpose of evaporating the moisture from newly made bricks before they are placed in the kiln and which comprises an arrangement of furnaces, flues, registers, inclined tracks, and movable trucks, whose details of construction and operation I will now proceed to describe.

Figure l is a transverse section of a dryinghouse embodying my improvements, one half of the house being shown as filled with brick and in operation, while the other half is empty and in condition for receiving brick. Fig. 2 is a longitudinal section of the same with portion of the house broken away; and Fig. 3 is a plan of the house and its accessories.

The house or dryin g-chamber proper consists essentially of walls A, floor B, ceiling G, and roof D, of which the walls, floor, and ceiling should be made of materials that will resist the heat radiating from the furnaces. Running longitudinally of the building are a number of piers, E, which are carried up about half way to the ceiling, and these piers serve to support tracks F, which incline toward the deliveryend of the house, as seen in Fig. 2. Adapted to traverse these tracks are the flanged wheels G of trucks H, upon which the newly-made bricks are hacked. It is preferred that the bottoms of these said trucks should be perforated, or else made of iron bars a suitable distance apart from one another, so as to allow the heat to circulate freely around the bricks. Built into the walls A, and also into one or more of the piers E, are furnaces I, whose tops, sides, and inner ends are perforated at 17, and said furnaces are provided with doors J that are external to the house. These furnaces are provided with ash-pits K, having doors is. Ar ranged transversely of the building, and beneath the floor B, is a flue, L, whose discharging-end communicates with the chimney M, and the bottom of this flue inclines toward said chimney, as shown in Fig. 1. The floor B is pierced at suitable intervals with openings 1) I that communicate with the subterranean flue L, and these openings are furnished with hinged dampers or registers N. The registers N are capable of being opened or closed by means of rods 0, which project through the walls A, and said rods are provided at their outer ends with handles 0. 1- is a catch-basin or cistern, into which all the water of evaporation is conducted by flue L. If preferred, the upper part of the house can be divided into two equal portions by the longitudinal partition B, thereby allowing either half of the drier to be used independently of the other half, or alternately therewith but in this case it will be necessary to provide said partitions with shutters S that can be opened when the entire building is to be used, so as to establish a perfect circulation of air within it. The ends of the house are provided with doors T that are large enough to admit the trucks with their loads of bricks. Pits U facilitate the feeding of the furnaces and attention to the damper rods.

The operation of drying .bricks within this house is carried on in the following manner: The newly made bricks are first properly hacked upon the trucks H, and the latter are then shoved upon the elevated ends of tracks F, and allowed to descend the incline until they reach the lowermost end of the same, where their further progress is arrested. ()ne truck after another is thus placed in the building until it is filled, when the doors T are closed and fire is started inthe furnaces I. The fire, smoke, and heated gases emanating from the furnaces ascend and completely envelop and circulate around the bricks, and the result is that the latter are thoroughly and uniformly dried in a short time, and in the most economical manner.

As there are no openings or other outlets in the ceiling for the escape of heat, all the prod nets of combustion are compelled. to descend and escape through the opening 1) into the flue L, as indicated by arrows in Fig. 1. These openings not only serve as outlets for the smoke from the furnaces, but they also allow all the water of evaporation, that naturally falls to the floor, to escape into flue L, which conducts said water into the catch-basin P. Whenever it is desired to retain the heat within the build-' ing for any length of time, the dampers N are closed as long as necessary, and by opening or partially opening them, the temperature of the drier can be lowered to suit circumstances. All the moisture having been evaporated from the bricks by the above-described process, the fires in the furnace are drawn, the doors of the house opened, and the trucks allowed to run out at the lowermost end of the incline. In the meantime, the other half of the furnace, having been charged with bricks and fuel, may be set in active operation for burning another batch.

In the drawing the furnaces are represented as being made of metal, but it is evident that they may be constructed of brick, a sufficient number of the latter being omitted at intervals so as to leave openings for the escape of heat into the interior of the house.

The perforated furnaces, by allowing the flames to escape therefrom, add greatly to the economy and efficiency of the apparatus, and enable the drying of bricks with much less fuel than could be done if said furnaces were im perforate.
