LUMBER-DRIER.

SPECIFICATION forming part of Letters Patent No. 347,387, dated August 17, 1886.

Application filed December 28, 1885. Serial No. 186,953. (No model.)

To aZZ whom it mayconcern:

Be it known that I, GEORGE W. SHARER, a citizen of the UnitedStates, residing at Terr-e Haute,in the county of Vigo and State of Indiana, have invented certain new and useful tion and utility in the arrangement of the part which will expedite the drying and-attain the best results;

The invention therefore consists of constructhe air-ducts; Fig. 5, avertical section on line as m, Fig. 2; Fig. 6, a side elevation of part of the drier, and showing the interior of the shed; Fig. 7,.an end elevation of part of the drier and the flue and chimney; Fig. 8, a section on line 3 y, Fig. 2; Fig. 9, a section on line 2 2, Fig. 8; Fig. 10, a section on line 1' r, Fig. 2, and looking in the direction of the arrow 1 Fig. 11, a section on line 8 s, Fig. 10, the damper at closing the ventilating-tube d; Fig. 12, a side elevation of one truck; Fig. 13, an end elevation of the truck shown in Fig. 12; Fig. 14, a section of the truck taken through the wheel; Fig. 15, a side elevation of the means for lifting the door,and Fig. 16 an end view of the same.

A represents the furnace,having grate-bars a, the bridge-wall a upon which the grate-bars rest, the air-vault a covered by bars or perforated plate c v and connected with the ashspace a by duct a and a sliding door, a. The furnaces (two of which are shown) are proper distribution of the air.

made of brick or other suitable material and provided with buck-staves a through which rods a? pass to corresponding buck-staves (not shown) on the back of the furnaces. Upon each side of the furnaces are buck-- staves a", connected together by the rods c These buck-staves a and a and rods a a l bind the furnaces securely together, whi ch fur naces are protected by the roof A.

Leading fromthe furnace are flues A fllined for part of their way with firebrick, and extending to the soot-flue A having chimney A outside of the drier. This chimney is provided with a regulating-damper, A, having rods a and a and lever a.

. In the upper wall of the furnace, immediately over the fire-box,are the air-fines B, extending from the front of the furnace to the chamber B, having the large outlet-duct B",

which rests upon the top wall of flues A, and extends about two-thirds (t) the length of the drier, and terminating in a cross flue or duct, B", having its upper side perforated for the The duct B is of less width than the width of all the fines A, so that heat from the latter will be radiated into the drying-chamber, as well as absorbed by the air passing through the ducts.

Piers O are arranged at suitable intervals on each side of fines A and each is provided with a wooden cap, 0, and a block, 0, which rests upon cap 0 and supports the beam G,extending the whole length of the drier. At the sides of the flues are piers 0, upon which are placed the beams 0 extending the whole length of the drier. Gross-beams 0* are placed across the beams O and G and supportthe longitudinal beams 0 upon which the tracks 0 are laid. Between the piers O and 0* and cross-beams 0* are the metallic partitions G which form the compartments Gflthat receive radiated heat from the fines, and also prevent the-heat from one compartment from passing into another. Between the tracks 0 are the partitions (3 which are practically a continuation of the partitions G and proj ect upwardly between the tracks to or slightly above the top of the trucks. These partitions O are made of rubber, felt, or other elastic material, so that when the car is moved it will give sufficiently to permit it to pass and have at the same time contact with the contents of the car to prevent the heated air from duct B from passing said car or cars.

The walls of drier D are made of brick or other suitable material, embrace the furnacefiues A" and the parts above them,and capped by the roof D, which is preferably made slanting from the center to the sides and provided with felt partitions d These partitions prevent the heated air from the duct B from passing over the ears. At the front end of the drier is an air-escape duct, D, for the dryingchamber. This ductis provided with a transverse partition ,D, having the vcntilatin g-tubes I), Figs. 2, 10, and 11, each having a damper, d, operated by a rod, (1, so that the opening in the tube may be opened or closed to regulate the exit of the heated air passing from the drying-chamber.

The front and rear ends of the drier are each provided with doors, (marked, respectivcly,D and D The door D is provided with bar I), to which is attached at each end a cable, d which pass over pulleys d on a beam, 1), and are provided with weights (1, for an obvious purpose. The rear door, 1), may be operated in the same or any other desired way. Upon the rear end of the drier is a shed, D", where the articles are cooled off before being carried away.

The trucks E (shown in detail, Figs. 12, 13, and 14) consist of two longitudinal beams, E, joined together at their ends by cross'pieee c, and carrying the rigid axle e for the wheel 0', which is free to revolve on the axle and move longitudinally thereon, so that if there are any inequalities in the track the load above will not be disturbed. These trucks, as shown, are complete in themselves and run upon a single track, but take two or more of them and the load, if lumber be used, to make the car, as shown in Fig. 8. If articles too small to extend across the space between the trucks are to be dried, then planks or other material can be laid across the trucks for their support. \Vhen the car has reached the shed and it is desired to use the trucks again, they can be easily transported from one end of the drier to the other, or that having the platform A.

The operation of the device is as follows: After the fires have been started and the driers evenly heated by radiation from the flues A" and the hot air admitted thereto, the cars are run into the drier through the front door. The heat radiated from the fines A passes upwardly to the cars and reheats the air admitted through the air-duct, which air has become more or less cooled by absorbing the moisture of the articles dried. In other words, heat is added to the current of air at points to give greater efficiency to the drier. After the material has been thoroughly dried it is passed across the compartment in which the crossdnct is placed, to permit the contents of the ear to become partially cooled before passing the latter into the shed. When lumber is dried in this way no checks are made.
