` By'my'inveuton I utilize the wneie heet from Ae. brick 'kiln by conveying the' heated noir from the 4kiln to. thel drier andl admitting '30 it toeny one' orali of the three chmnbeieo' Referring to the drawings, 1 is the casing tain; 2, which are nldepted` to rollers 3 and whichcun'be to allow trucks to pass from oesectionto another and to be lowered -atei the trucks are in position. In the present instance, there are three iongituchnai tracks 4:, which extend entlrely through the drier und on these tracks are trucks cern- 46 'ing the bricks. The bricks are piled on the trucks insuch a' manner thatalr can circle late freei through the spaces between the bricks. t the forward end of the drier is n door 6 in the form of a curtain und'at the dischgrge end of the drier is n door 7, nl so in the iu-Lm of'a curtiii. 8 is u series .nf circulating 'felis located4 in jglgg upper, portion. o fthe drier, and, inthe present instance,

The waste heut from the kiln ieusi'x'llyfl/V disclulrged from the kiln at about 500 d ggz-eee F., und the temperature moy be reduced by the admission of fresh air throu h the duc?J or flue 18 to about l2300 de eesgF., or. much iower, und by reg-uistn V.t edampers the 7x-oper de ee of heut can. maintained in tie Severn 'sections of the' drier. The' dempers are preernbly controlled by automatic dnmpeiyreguintors which may'be ofany of the common types.

By this construction, the zir passes from the discharge end of the drier toward the ,iorward end, consequently, the moisture in the air is greater at the section where the bricks are Vadmitted to the drier than :1t the point where they are discharged therefrom, consequently. the bricks are subjected to the moist, heated air in the first section of the drier and. to heted nir of :t less degree in the second section, so that the moisture is held in the bricks to prevent the bricks from drying on the outside before the interior is thoroughly dried. Vi'hen the bricks pass into the third chamber the)r nre subjected to dry heat which completes the drying of the bricks so that when they nre delivered et the discharge end of the drier they are thoroughly dried.

l preferably extend the fresh air duct or fine 18 at the side of the drier. as shown at. 31, and connect it with the sections a und b through ducts 32 und 33 respectively, euch having a damper therein. By this mea-ns, the temperature in the several sections can be reduced, iffound desirable.

I claim; l

1. The combination in a, drier, of a series of compartments, each compartment having e dry ing chamber; means for supporting the material tombe dried in said chambers; lines for conducting hot. air to the. several chambers.; dues connecting the several chambers; and an exhaust fine communicating with one ofsaid chambers so as to exhaust the moist air from said. chamber.

2. The combination in adrier, of alseries of compartments, each compartment having a drying chamber; means for supporting thel material to be dried in the several chambers; movable curtains dividing the chambers so that material can be transferred from one chamber to another; a flue for hot gases communicating with the last of the series of chambers; flneslconnecting the several chambers; and an exhaust tiue communicating with the first. chamber so-that the air, as it passes fromv one`,c`hamber to another, will collect the moisture and willbe finally discharged from the'chamber into which the material to be dried is rst entered.

3.. The combination in n brick drier, of n series of compartments; curtains separan ing the compartments; tracks extending through the compartments so that cnrs carrying the bricks can he moved from one compartment. to inother; n [ine for hunted uir communi eating with euch of snid compartments; lr-impers for cutting olf any one ot' the compartments; fines forming communication between two adjoining compartments; :i damper in each flue; und :in exhaust fiue eommunicating n'ith the first compartment to remove moist. air from snail compartment.

al. The combination in n brick kiln, of a series of compartments; n. track extending through the kiln so ns to nllow trucks on which the bricks nre mounted to be transl crred' from onel eompnrtirent to :mother during the drying process; menus for circulating nir in euch ot' said eonipnrtments; n'flue for conducting,r hot. a ir und communicating with the severalcomlnirtments; dempers for regulating the passage of the. nir to the several compartments; a flue. for admitting fresh nir to the first con'ipm-tn'icnt.; fines con nectmg one compartment with another; u. demper in erich flue; .find n n exhaust [inc for the discharge of moist air in the first compartment so that the nir in the first compartment will be moist while the air in the last compartment will he dry in order that the moisture may be held in the. bricks of the first compartment to prevent the bricks from drying` on the'outside before the interior is thoroughly dried, while the bricks in the last compartment. are subjected to dry heat which completes the dryingof the bricks. The combination in adrier, of -si series of compartments, each compartment having a drying chamber; means for suppolting the material to be dried in said drying charnbers; lues for conducting hot air to the sev-4 eral chambers and fines for conducting fresh air to the said chambers; ues connecting the several chambers g dempers in said fines: and' means for exhaust-ing the moist nir from one of said chambers.

In witness whereof I ax my signature..
