MANUFACTURING BRICK.

' Specification of Letters latent.

Patented Jan. 1, 1907.

Application filed May 19, 1905. Serial No. 261,104.

To a who/1 1, it may concern:

Be it known that I, ALBERT A. GERY, a citizen of the United States, residing in'the city of Reading, Berks county, Pennsylva nia, have invented certain new and useful Improvements in Manufacturing Brick, of

which the following is a specification.

My invention relates to the manufacture of brick or other material which .8 successively subjected to drying, burning, and cooling treatment; and my main object is to provide for ell'ecting a more positive and uniform action of passing air upon the loosely-piled material for the purpose particularly of thoroughly drying the same preparatory to the urning operation.

The invention is particularly applicable to the continuous method of burning in tunnelkilns, which is fully described in my pending applications, Serial Nos. 228,128, 230,001, and 242,500, wherein the green material is periodically introduced at the entrance end of the tunnel and is successively dried, heated, burned, and cooled as it progresses to the exit end, the tunnel being constantly filled with material in different stages of treatment, and said material being carried upon a moving tunnel-floor made up of a series of abutting cars.

Having ascertained from practical experience that the thorough and uniform drying of the whole mass of green material is.a mat ter of primary irn ortance, the failure of which rs a basic operation can be in no way remedied by succeeding treatment, .l have heretofore employed special methods and means of d rying,involving both indirect heating of the loosely-piled material and the direct action of heated air, as described in my pending application, Serial No. 242,500, above referred to.

i In my present invention lprovide for further improving the drying operation by posi tively insuring the effective and uniform action of the passing air upon the whole mass of material to be dried, the main novel features consisting in maintaining the air in a somewhat-compressed condition during its passage through the drying-chamber and in so controlling its withdrawal as to most ell'ectively. anduniformly utilize the same therein.

The invention is fully described in connection with the accompanying drawings and is ipecifically pointed out in the claims.

igure 1 is an end view, partly in crosssection onthe line 1 1 of Fig. 2, of a seriesof parallel tunnel-kilns embodying reqiusite means for carrying my invention into effect.

Fig. 2 is a longitudinal section of an end portion of a tunnel, shown to reduced scale, but corresponding mainly with Fig. 1.. r

In carrying out my present invention I preferably employ, as shown, a kiln and carfloor construction and an air-pipe system a similar in the main to that set forth in said pending application, Serial No. 242,500, as my improvements are particularly thereto. In this construction the abutting car-floors 1, upon which the brick or other material is periodically introduced to and gradually progressed through the tunnel 2,

adapted are each formed with one or more longitudi 1 nal air-conduits 3 below the floor-surface, andsthese conduits of each car-floor communicate with those of adjoining car-floors to form a continuous passage or passages extending the full length of the train. Atmospheric air drawn into these passages through the foremost car of the train at the exit end of the tunnel flows rearward through the train, abstracting heat in the first place from the outgoing floor-sections and then from the highly-heated inner tunnel floor-sections. When this heated air reaches the entrance end of the tunnel, it delivers its heat in part tothe cooler incoming fioor-sections, so as to indirectly heat the lower layers of brick piled on said sections and the lower strata of air in contact with said brick, and is finally utilized directly upon the incoming brick by delivering it. into the incoming end portion of the tunnel through a suitable pipe system. This latter comprises, as shown, a connecting airpipe 4, removably attached to the rear end of each last-entered car-floor, a fixed vertical air-pipe 5 therefrom to a common transverse. pipe 6, a fan-chamber 7 in connection With,

the latter, and a main blast-pipeS therefrom,

branch blast-pipes with extensiong, having 11 12, extendin into'the tunnel at a height above the movable car-floors and dischar ng the heated air through suitable perforations into the looselywhich is more ful y described in my pending application mentioned.

The heated air thus brought into contact with the undried brick in the tunnel and laden with moisture therefrom, is finally discharged through a transverse fiue'l3, connecting a series of tunnels with a common outlet or iled undried bric'k,- all of l drying end of the tunnel from the side walls thereof in a manner similar to the indirect heating etlected through the movable hollow floor-sections; The drying portion of each. tunnel is also cut off from communication with the inner tunnel during the intervals between the introduction of new cars by the vertically-movable partition 17.

The construction and operation already described enable good. results to be secured;

but I have found that the passing air may be better utilized'and more uniform action attained by more positively and elficaciously controlling the contact and flow of the air through the brick. To this end I convert the entrance cndof the tunnel rearwardot' the movable partition 17 into an approximately air-tight chamber having pro )orly-located and adjustably-restricted outiets, whereby the air forced into said chamber may be sutficiently compressed therein to insure uniform contact thereof with every portion ol" the loosely-pilcd brick, and the low of outgoing air at all points in the length of the chamber may'be properly controlled to secure e ual and thorough treatment through. out. he end closure 18 oi the tunnel is adapted to close the latter, so as to practically cut off the inflow of atmospheric air therethrough to the drying-cliamber, thus ermitting a sullieient compression ol air to e readily maint ained by the forced delivery through the blast-pipe 12. A series of lowdown side outlets 19 tron'rthcdryiiig-chamber communicate through suitable conduits 20 with air-p assages 21 each having d am per-controlled communication with the transverse. flue 13 and the outlet or stack 14, whorebya roperly restricted and distributed liowoi air From the bottom of the drying-chamber to the latter is secured. By means of the unilorm pressure and regulated flow of air thus secured mall partsoi the drying-chainber, in connection with the indirectlyheated side walls and floor, themost etl'ective and uniform treat- I ment of the brick may be positively secured.

The amount of heated air delivered into the drying-chamber and withdrawn therefrom is adapted to effect the thorough drying of each car-load of brick during its normal passa e therethrough.

. RNhat I claim is- 1. The improvement in manu'l'aeturine brick or the like which consists in subjecting the same while loosely piled in a dryingchamber to the action of iii-forced air which is temporarily stored in said chamber under GOMI' ession while circulating thercthrough.
