Leners Patent No. 93,526, ,dans August 1o, 1869-.

The' Schedule referred to in these Letters Patent and making part of the lame.

To all whom it may concern v Be it known that I, J EREMIAH FISHER, of the cit of Reading, inthe county of Berks, and State of' Penn'f sylvania,lbave invented certain Improvements in Treat# ing Clay and Drying Bricks; and I do hereby declare that'the following is a full, clear, and exact description ofthe same, reference being had to the accompanying sheets of drawing, and to the letters of refer` ence marked thereon.

My invention consists in the mechanism used in the" preparation and transportation ofthe clay,and in drying the raw bricks, but not in the moulding of the same, substantially as is hereinafter shown and described.

On reference to the accompanying sheets of drawings, making part of'this specication- Figure 1, sheet l, is a view in perspective, showing my improvements. v

Figure 1, sheet 2, is a side view, the hoist for raising the hot-air cap not being s'hown'; and

Figures 2 and 3 are side views of the truck used for taking the clay from the hopper.

Figure l, sheet 3, isI an end view, and

Figure 2, a plan view of the turn-table. Similar lettersrcfer to similar parts in the several views.

A and B are uppcrand lower floors. The first has the clay-pit O, for receiving raw unground clay, and to that end is slightly lower than the door, to prevent it from spreading, and also forthe more readily con- ,veying-to the hopper' D, the upper end of which is on a level` with the upper floor, the lower end being, situated a short distance beneath it, forming, as it were, a communication or passage between the floors. The hopper .is similar .in construction to those usedv for grinding'clay.

. As the claypasses frprn the hopper, it is caught by the clay-truck L, which, when loaded, is moved on to the door of the elevating-platform E, which 'is raised by the hoist of windlass F, of any suitable construe tion, and fixed to any suitable framing above the upper iloor A, immediately over the'centre of the platform, suitable guides, c aI a @,being used to keep the platform from shifting while elevating,

When the oor of the elevator attains the level of the floor A',the truck is turned in the proper direction by means of the turn-table M, on which it stands, and

passed to the brick-maker.

After the bricks are moulded, they are piled under X the cap G, it 'being raised to a suitable heightA by the travelling-windlass or hoist H.

'Gare must be taken to stack the bricks in such manner that a current of hot air can be readily forced between them, after which the cap is lowered.

The fand, which connects with `the exhaust-end of the furnace, used for generating steam for driving the machinery, is set in motion by means of abelted pulley, driven from any adjacent shafting.

The hot air is drawn from the furnace, and forced into the hot-air cap G, and. passes in between the bricks, whereby they are thoroughly dried in an incredibly short time, after which it is drawn out by the opposite fan J. It will be seen,sheet 1, in red lines, and sheet 3, fig. 1 elevation, that the windlass His movable,'being carried on wheels, which are carried and travel on the tracks or railway c c, situated immediately over. the hot-air cap G, by which means the cap can be elevated and moved While the greenbricks are being stacked previous to drying.

'.lhe truck L forms the table on which the bricks are moulded bythe brick-maker, and to that end the top is made in two parts, which are hinged together at (l.

rlhe part e is capable of being elevated, to throw the clay toward the brickemaker, at his option, as follows:

g, iig. 2, sheet 2, (showing the side of the truck removed to exhibit .its internal mechanism,) is a toothed sector xed to the under side of the vibrating part e, of the top of the truck, depending vertically downward. h is a shaft passing transversely through one end of the truck; it carries the pinion k, gearing into the sector g.

It will be readily seen, as the pinion is turned by means of the handle or lever l, fig: 3, it causes the sector g to move .through the arcof a vertical circle, whereby the part e is made to take the inclined position shown at m, red lines, fig. 2.

After the part e is inclined, as shown, it retains that position through the medium of the toothed sector fn, depending from the part c on the outside of thetruck. When the part e assumes any given. angle, a catch, o, takes into the teeth of the sector 'and supports it.

I do not claim the devices herein shown, either severally or in combination, knowing them to be old; but

What I claim as my invention, and desire to secure by Letters Patent, isv i The arrangement herein described of the two-storied structure, as shown, provided with the clay-pit C, pugmilLD, truck L, elevator E, with its turn-table M and hoist F, hot-air cap Gr, with its fans I- J, and travellingwindlass I L'up'on its tracks c c,'all constructed and operated substantially as and for the purposes herein set forth. In testimony whereof, I hereunto sign my name to this specification, in presence of two subscribing witnesses. Witnesses: J EREMIAH FISHER.
