The annexed engravings are views of an apparatus, for drying malt, grain, &c, for which a patent was granted to T. E. Weed, of Wil-liamsburgh, L. I, February 24th, last year.— As it is expected that more grain will be exported this winter than during any ol the past five years, a good grain dryer is of no small importance for the purpose of preparing grain for safe and successful preservation during voyages, or when lying in storehouses.— Figure 1 is a perspective view ol the machine, and figure 2 is a vertical section. The same letters reler to like parts. a a are circular steam chambers made of two plates of boiler iron, having steam-tight joints, and so placed as to leave a steam space of about three inches between them for steam to circulate. The top plate has a plain surface, the bottom plate inclines to the centre, to allow the condensed afeanvjp pass 4"8own ihe hollow snait, lE B, and escape from the pipe, T. The shaft, B, is a pipe which extends through the centre of the apparatus; it is made in sections, and supports each of the chambers, a a, There are circular sheet-iron hot air pans, c c, supported by the arms, D, which are secured to shaft, B. These pans are larger than the steam pans or chambers, a a. The steam and hot air pans are arranged alternately above one another; the grain from the steam pans is scraped gradually from the centre to the circumference, then tails down on the larger hot air pans, when it is scraped to the centre, where there is an open space, then fails down on the steam pan, and so on from the top to the bottom of the series, when the grain or malt is discharged perfectly dry. F F is a frame work that revolves round.— The top part rests on the shaft, B, which is its axis. The bottom part turns on a ring on the shait which keeps it steady ; g g are scrar pers secured on the arms, H H, of the frame, F ; these scrapers revolve with the frame.— The scrapers which revolve on the steam chambers are set at such an angle as to carry the grain from the centre to the circumference ; those on the hot air pans are set at a contrary angle to carry the grain to the centre; they work the [grain spirally; I I are small chambers that extend around the centre shaft; J J are openings in said chambers, and extend around them; K is a pipe that has an opening into each of said chambers.— A current of hot air is forced into the pipe and passes into these chambers, and a thin stream of it llows through the openings, J J, and passes oH'irom the centre over the sur-i face of the grain on the pans (that is conti-i nually stirred by the scrapers) and through the grain tailing from the pans at the centre, this is for the purpose of carrying off all the vapor that rises; L is an iron bar, that supports the weight of the machine; m is a cross secured to the floor above; the rod, ", which is secured to the main shaft passes into it to hold the machine in position; 0 is a pulley I secured to the frame work for turning it; P is I a feeder which conveys the grain to the ma-I chine on the top steam pan, at the centre; Q l Q are guard plates on the frame, moving with it to keep tha grain from falling over from pans, c, but these pans have elevated rims, while there are none on pans, a. The "t-iimm pif"1 t"—mmu&y otgaui -fimii tlrg-WiteT, connects at R, with the main hollow shaft, from which it is distributed through the steam pans, a a. The above description will convey a clear idea of the nature, construction, and operation of this grain dryer. There are two claims in the patent; one for the main shafa, B, answering as a support and steam passage for the chambers, a ; the other is for the arrangement of the air chambers above the pans, c r., for the purposes described.— There are a number of features combined in j this rmrttited ta attract TKeTOTCTorTjEoSBTrp terested. It can be made ol any size and with any amount of surface. This machine has been thoroughly tested with every kind of grain. All grain shipped to any distance should be kiln-dried.
