Be it known that I, JAMES J. JOHNSTQN, of the-city and county of Allegheny, in the State of Pennsylvania, have invented a new and useful improvement in Brick-Briers; and I do hereby dcclar'e that the following isa full and exact description thereof, reference being had toIthe accompanying drawings, andxto the letters and figures of reference marked thereon.

The nature of my invention consists in the use of .a dry-house] prov'ided:witl1 :flues, air-conducting pipes, and u suction-fan, said fines, pipes, and fan soarranged with rel'ationto each other that pure air is drawn into k and heated in its passage through the pipes, and forced into the dry-house by the fun without any increase of the draught on the fire of the furnace. v p H My invention further consists in a peculiar form of the dry-house. and bcaringofii cars ortrncks, whichare so arranged with relation to each other that the heat in the dry-house? is hep't in close contact with the brick on the cars or trucks, the form of which readily permits the moisture and vapor to pass offfrom the bricl ,,which are so'arranged in tiers that thcy areexposei'l-to the evaporativeaction of thctdry-housefl the whole being constructed, arranged, and operating in the manner hereinafter described. I I

To enable others skilled in the art to makeand use myinvention, I will proceed to describe its constrnction and operation. In the accompanyingdrawings,'which form part of my spccific'ation- 1 Figure lrepresents a side-elevation'of my improvement fordryingbricks. i s

\ Figure 8 represents a side elevation of the same. I

J In the drawings, A is the dry-house, which is conifcrm when viewed in cross-section; and is formed of boards, sheet iron, or other suitable material. B represents the doors, which are hingedat the point marked 1, Under the floor of the dry-house A are lines f and g, which are connected with the boiler-furnace of the engine used for driving the machinery connected with. the manufacture of brick. In the heat-chamber of the boiler-furnace are two pipes, It and i, which run lengthways of the furnace. To the pipes k and z' are connected pipes m and n, which run longitudinally within the lines f and g, and connect with the case B of the fan. The fines f and g terminate in a. flue, J, which is provided with a stack, P. To the fan-case R are connected two pipes, 0 and s, which communicate with the interior of the dry-house. Through the dry-house runs a railway, x, for the cars or trucks. At each end of this railway should'bc switches x, for shifting the cars from the track a to the return track 22:. The cars or trucks 3/ should be made in the form represented in figs. 5 and 6. lhe boards for supporting the brick on the cars or trucks should be of sufficient length and breadth to hold six brick, as shown in figs. 7 and 8. These'boards with their lead of brick are placed on the shelves 1. of the cars or trucks y, as shown in fits, 6. I I The manner of cbnstructi 'ng the several parts of my improved brick-drier will readily be understood by the skillful mechanic from the above dcscripcion and by reference to the accompanying drawings. I will, thercfore, without further description of-its construction, proceed to describe its operation.

Having all things constructed and arranged substantially as herein described, the brick-as fast as they areuioulded are turned out on the boards, which are as fast as they are filled placed in theirpropcr position on the shelves of the car or truck, which, as soon as it has received its load, is run into the front end of the dry-house, which is its coolest part; and as each succeeding car is loaded and enters thedry-house, the cars whichpreceded them will be uioved fprward into a better part of the dry-house, thus gradually bringing the brick in contact with a. gradual increase of heat in the dry-house, thereby gradually and evenly drying the brick without liabi-litypfcracking them.- It will readily be observed that the form of the car or truck and the arrangement of the brick thereon will greatly facilitate the escape of the moisture and vapor from the brick, and at the same time expose thelnick' to evapora-tjve action of thedry-liouse. After the loaded cars have passed throughthe dry-house, they may by means of suitable railways convey the brick to the kiln, and the brick set foi the burning process. Each loaded czir or truck should remain-in the dry-house for about seven hours, which will be suflicientjtime for drying the brick so that they can at once he set in the kiln for burning. Pure air'is drawn I .into, the pipes k nndi, and from them passes along the pipes m and r. into the fan R, from which it is throw-n or forced through pipes o and 3 into the dry-house at or near its back end. (A represents the front end and B" the back end of the dry-house.) -It will readily'he seen and understoodthat pureair can be forced into and through the pipes h, i, m, and it into the dry-house, therefore I'do not confine myself to a single mode of supplying the dry-house with heated air. The heat of the boiler-furnace heats 'the pipes h and i, and the heat which passes. through the fines f and 9 will heat the pipes m and n, and the air passing throughall these pipes, cpnibined will be heated and put in motion through the dry-house for the purpose set forth. The smoke, dust, and other refuse of combustionof the furnace are conveyed along the fines f and 9 into the flue J, and from it up through and out of the stack P. '-By this arrangement of the fines, pipes, and'fan hereinbet'oi'e described, the flucs of tho boiler-furnace serve atriple purpose, to viit, they-convey the smoke-and dust from the boilerfurnace, they heat the floor of the'dry-honse, and they .heat'and formchambers for the air pipes. v

The skillful mechanic will readily notice another very importunt fcature in niy iuventiom to wit, that I can increase the force of the heated air in the dry-house without any increase of draught to the furnace. This is accomplished by the use of the pipes h, i, an, and n, in combination with the fan. Another feature connected with my improved brick-drier is that its coolest part is next to the fire which imports heat to the whoie of the dry-honse. o I v i In case it should be desired, the escape steam from the engine may be conveyed'through pipes on 'the', under side of the roof of the dry-house, (as indicated by dotted lines'iu fig. 1,) and used for imparting bent to the interior of the dry-house. i

The advantages obtained by the form, construction, and arrangement of the severalparts of my improvement in brick-driers are too apparent to require any recital or enumeration, for any mechanic skilled in the art of drying brick will see at a glance that all the requirements for the hrichwdrying process are fullysupplied by my invention, as herein described and set forth.

Haring thus-described thcnatnre, construction,- nndopcration of my improvement, .what'l claim as of mv invention, is-

- vl ilh e eoniformed dry-house, in combination with the car, (when viewed in cross-section,) provided with ilues connected with the boiler-furnace and its stack, substantially as herein described and set forth.
