GRAIN-DRIER FLO-OR.

SPECIFICATION formingpart of Letters Patent No. 233,301, dated October 12, 1880. Application filed June 8, 1880. (No model.)

To all whom it may concern Be it known that we, WENZEL TOEPFER and FRANK TOEPFER, both of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Grain-Drier Floors; and we do hereby declare that the following is a full, clear, and exact description thereof.

Our invention relates to the trays used in grain-drying kilns, and its object is to facilitate the use of thin perforated metal as floors for the same.

In the drawings, Figure l is a perspective view, and Fig. 2 a section, of a portion of a tray embodying our invention.

Heretofore drying-trays have generally been covered with wire-gauze stretched over their frames and secured to them permanently, or the drying-floors have been made up of perforated plates placed loosely upon the rafters or riveted together by tie-straps; but ithas been found by experience that wire is apt to give and stretch under the weight of the workmen who shovel and distribute the grain, and form ridges, which the blade of the shovel often impinges to the extent that the Wire becomes worn and broken at points just over the crossties; and the perforated metal plates used must be very heavy, else they do not afford a hold for the rivets, and being thick they hold the lodging grains in an upright position to be broken by the shovels, while thin metal has no tendency to gripe the rivets, but either lets them fall through or be dislodged by the shovplate drawn out.

els. Therefore, with a view to the use of thin perforated sheet-iron, we construct the frames of our trays in sectionsA A, of metal, between six and ten feet long and between ten and thirteen inches wide, and we rivet or bolt a flanged holding-plate, a, to one end of each frame, and then bolt these two frames together. The floor B is now placed upon the frame, and one edge thrust under the horizontal flange of the holding-plate a. The side holdingplates are riveted onto the frame, and a holding-plate similar to a placed on the other end. Each section is floored in a similar manner and bolted to its mate until the required length of tray has been reached, and whenever it becomes necessary to remove the floor of any section the side holding-plate of that section need only be removed and the Thus we are enabled to use very thin flooring, and have it serve the purpose better than any other now in use.

What we claim is A tray for grain-driers, consisting of sectional frames A A, perforated plates, and holding-plates a, the sections being bolted together, as described.

In testimony that we claim the foregoing we have hereunto set our hands this 29th day of May, 1880.
