. SPECIFICATION forming part of Letters Patent No. 486,931, dated November 29,1892. Application filed July 21, 1892. Serial No. 440,775. (No model.)

To all whom t may concern.-

Beit known that I, NATHAN HARPER, a citizen of the United States, residing in Newark, county of Essex, and State of New Jersey, have invented certain new and useful Improvements inDrier-Cars forBricks; and I do hereby declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, aud to letters of reference marked thereon, which form a partof this specification.

The object of this invention is to provide a drier-car for bricks or other clay products, whereby a large saving can be eected in the amount of fuel heretofore required in the drying process, while by the same means the capacity of the car and also of the dryingchamber are both largely increased without any addition to the size of eit-her.`

The invention consists in the improved drier-car and the combination and arrangements of the various parts thereof, substantially as will be hereinafter more fully described, and finally embodied in the clauses of the claim.`

Similar letters of reference `indicate corresponding parts in each of the several figures.

Figure l is a side elevation of my improved drier-car, together with its load of pallets carrying the bricks. Fig. 2 is a similar view of an ordinary drier-car, drawn to the same size as Fig. 1, and illustrates the dilference in the respective capacity of the two structures and in the disposition of the load on each. Fig. 3 is an end elevation of Fig. l, placed in a drying-tunnel, and illustrates how completely the load on the improved car occupies all the space availablewithin the tunnel. Fig. 4 is a top plan view of the improved car, and Fig. 5 is an enlarged sectional view on line Fig. 4.

In said drawings, a a represent the side bars or frame of the improved car, which are secured and held firmly in their respective positions by rods or braces c or in any other desired manner. Projections el extend upwardly from said side bars to receive or sustain boxes or bearings e and axles f carrying wheels g, all of which are secured in their respective places by any of the usual means.

tially all the space from the surfacev of the.

rails to the top of the drying-tunnel B to be occupied with bricks. The top of said side bars or frame may of course be constructed -at any height desired below the top of the wheels.

Should the top of said frame be'carried high The pallets h, containing the bricks enough to receive the axles of the wheels, the

upwardly-extendin g projections would in such case have nothing to sustain but the brick pallets placed thereon.

In all drier-cars heretofore used the top of the frame or sidel bars has always been arranged as high or higher than the top of the wheels, as illustrated at o', Fig. 2, whereby all the space between the top of said frame and the surface of the rails i has been unoccupied with bricks, therefore unutilized. As thus constructed the area of the unoccupied space beneath the car is nearly equal in extent to the combined area of all the spaces between the bricks, and as this latter area is divided by the bricks into a `largenumber of narrow channels which greatly impede the passage of the air-currents, while all the space beneath the car is united in one large open channel, the result is that fully one-half 'of all the heated air drawn through the drying-chamber passes beneath the car without coming in oontact with the ,bricks thereon and is thus wasted, thereby causing the loss of about onehalf the fuel used. On my improved car the bricks can be loaded close down to the surface of the rails, thus compelling substantially all the air traveling through the drying-chamber to pass directly between the various courses of bricks, thereby utilizing the heat to the fullest possible extent and reducing the consumption of fuel in a corresponding degrec.

By comparing the load on the improved car,
