IMPROVEMENT m BRICK-CARRYING CARS.

Specificationfonning part of Letters Patent No. 75,243, dated March 10, 1868; Reissue No. 8,027, dated To all whom/it may concern:

Be it known that I, J OHN K. CALDWELL, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Brick-Carrying Oars and I do hereby declare that the following is a full, clear, and exact description thereof, that will enable others skilled in the art to which it appertains to make and use the same, reference being had,

.to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Figure 1 illustrates, in perspective, the construction of my improvement- Fig. 2 shows,

by an enlarged view, the shape of the recesses in the supports; and Figs. 3 and 4=show the shape of the supports and tables, the upper ones of which are elevated, and are in transverse vertical section. a

- My inventionconsists, primarily, in so constructing the tables and supports of a drying-.

'car that the former may be turned up or folded eitherto one side or to the other, at pleasure,

on the latter for convenience of loading or unloading.

My invention further consists in so constructing said tables and supports that, when the former are turned up or folded, each. of

said upper tables shall be out of the way of loading or unloading the next table below.

-My invention still further consists in so constructing said tables that they shall have a flat bearing-surface on which to-be support-e when raised, as well as when lowered.

To enable others skilled in the art to make and use my invention, I will proceed to delength that sufficient space will be left between eaeh two tables, b, to receive alayer of bricks on their sides, edges, or ends, as may be preferred. The shape of each of these notches is shownin enlarged view in'Fig. 2, c being the ledge on which each table rests when down, 0 the incline on which the edge-of the table'rests'when thrown up, and e the tenon, on

January 8,1878; application filed November 27,1877.

which each table I) is pivoted by a mortise, e, 'iu the edge of the table. Then, when each table b is raised, as illustrated by the two upper tables in Fig. 1 its lower edge, rolling over the tenon 0, will be carried back from the'ledge c to the incline c, and so be more perfectly removed out of the waypf loading or unloading the next lower table. i

Each of the two side edges of the tables bis formed with a mortise, e, and the supports on both sides of said tables are provided with a corresponding tenon, e, as shown. By this arrangement the tables are, in efl'ect, hinged on two sides, and these hinges are yet of an open construction, so that said tables may be raised from either side at pleasure,each table I turning as on a pivot, no matter on which one of its two sides it is raised.

The angle which the incline 0 makes with a horizontal surface may be varied, according as the tables areraised more or less nearly vertical, the object being to give an even surface on which to rest the edge of each table b.

To load the car, I commence with the lower table, all the others being raised, and to unload commence with the upper table, and raise each table as it is unloaded.

. The tables b, when raised, may be supported in any convenient manner by braces d or books d, or by other suitable well-known devices.

.The tables b I make of slats, as shown, with suitable openings between for the free dissemination of hot air or steam between the bricks, or in any other known way whereby the same result will be secured.

It will be observed that, as shown in the drawing, the tablesb may fold over either way, or, if so preferred, only one way. They may in like manner be made to turn up at either or both ends, or at any desirable point between the sides or ends.

In this way I construct a car for drying brick, 8w, convenient for use, of moderate cost, durable, and ed omical of space.

What I claim as m invention, and desire to secure by Letters Patent, i s

1. A drying-table having supports on two sides, said table and supports being provided with open hinges, which will permit the table to be raised from its support on either side,

turning pivotally on the support of the other side, as and for the purpose set forth.

2 a goes 2. A drying-table, b, having mortises e in its edges, in combination with supports a,

formed with tenons c, substantially as shown and described.

3. A series of tables, b, resting and turning in recesses in the supports a; in a drying-car,

substantially as set forth.

4. In a drying and bearing car, the supports a, having ledges c, inclines c, and tenons e, substantially as and for the purpose set forth.

5. The combination of the tables b, supports a, ledges c, inclines n, and tenons e, in a drying-car, substantially as and for the purpose specified.

6. In a drying-car a table, b, sustained upon supports a, and adapted to turn upon one or eitherof its ends, in the manner herein described.

In testimony that I claim the foregoing I have hereunto setmy hand this 23d day of November, 1877.

JOHN CALDWELL.
