MALT-DRIER.

SPECIFICATION forming part; of Letters Patent No. 325,018, dated August 25, 1835.

A pnlicaticn filed March 2'7, 1835.

T0 at whom it may concern..-

Be it known that I, ADAM SCHULTZ, of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Apparatus for Drying Malt, of which the following is a specification.

This invention relates to apparatus for drying maltand other material; and it consists in the novel combination of devices hereinafter described, and specifically set forth in the claim, reference being made to the accompanying drawings, illustrating my invention, in which Figure 1 is a side elevation of my improved malt-drier. Fig. 2 is an end elevation, and Fig. 3 a plan view, thereof. Fig. 4 is a detached plan of the malt-feeder.

Similar letters of reference indicate similar parts.

The machine consists of a frame-work, A, of wood or iron, upon which are mounted the traveling floors or aprons C. These aprons are endless bands of wire-cloth of any desired mesh, stretched around the hollow drums B. The drums are mounted upon shafts or gudg' eons b I), provided with journals which turn in bearings secured to the frame-work A. The boxes or bearings of the shafts b, at the left side of the machine, Fig. 1, are rigidly secured to the frame-work, while the boxes of the shafts I), at the right side of the machine, are adjustable in a horizontal direction by means of the tempering-screws 7), whereby any desired tension may be given the wire-cloth aprons (J.

Mounted upon the side rails, A, of the framework A are cross-ties (t a, upon which rest and are secured the iron rails c 0. These are set close under and parallel with the motion of the aprons O, and prevent an overstrain of the latter by the load of malt.

Between the upper and lower portions of the aprons G steanrheating pipes G are placed, through which steam circulates and furnishes the heat required to vaporize the moisture in the malt. These pipes are arranged to receive live steam in the lower tier within the lower apron O and pass the same from the lower tier to the tier next above, and so on to the uppermost tier of heating'pipcs in the ma 0 chine.

Sprocket'whecls D, of uniform diameters,

(X0 model.)

are keyed to the shafts of the drums B, around which are trained the link-belts 1*], whereby the drums at the opposite ends of the machine are caused to revolve by positive connectors and at the same speed. To one end of the shaft 1) of the upper drum, B, a worm-wheel, H, is keyed, into which the drivingworm H meshes. The worm is keyed to the drivingshaft 71, which turns in hearings in the housing H, secured to the flll']l6-\\'Ol1( A. H may be a spur-wheel or belt-pulley to receive the power required to operate the machine.

Spur-wheels F, keyed to the shafts b of the drums B, give motion to all the drums below the uppermost one. These are of uniform diameter, and cause the drums B and aprons C to move at uniform speed, and, as shown by the arrows in Fig. 1, to move in opposite or alternate directions. Thus the apron at the top of the machine travels from left to right, while the apron next below travels in the opposite direction, or from right to left, the alternate aprons traveling in the same directions. In this manner the maltis carried from the hopper J to the right side of the machine, there dumped upon the end fender, K, which directs it upon the apron 0 next below, which apron carries it back to the left side of the machine, where it is dumped on the end fender, K. This in turn directs the malt upon the apron (1 third in order from the top of machine, which again carries it from left to right, and so on according to the number of aprons, of which there may be any desired number in the machine.

The hopper J is provided with a toothed feed roll or agitator, J, turning in journalbearings in the ends of the hopper, and driven from the upper drumshaft by the sprocket wheelsj j and link-belt J A fixed comb or rack, J is set in one side of the hopper, by means of which and the feed-roll the malt is regularly supplied in granular form from the hopper to the upper apron G.

The aprons G are in width equal, or about equal, to the length of the drums B, and are attached to the linlebelts E by the clips or lugs e, which project inward from the belts, as shown in Fig. 3, and are riveted to the edges of the wire-cloth apron. In this man nor the aprons are uniform] y strained through out their length or circuit, and the drums B are simply carriers around which the aprons are guided; but the driving strain required to move the aprons O is obtained directly from the link-belt E through the clips 6, as described.

L is a hood or inverted hopper, placed over the machine, which collects the vapor arising from the damp malt, and M an eXhaustfan, which draws the vapor from the hood L down through the pipe L and expels it from the room in which the machine is worked.

70 7c are side fenders, secured to the frame A upon each side of the machine, to direct the malt inward from the edges of the wirecloth apron C while falling from one apron to the next below.

The operation of the machine is continuous. Motion being given the drums B and wirecloth aprons 0 through the driving-gear or pulley H, worm and worm-gear H H, and spurgears F, and sprocket-wheels D, and link-belts E, the malt is regularly supplied from the hopper J to the upper of aprons C, while upon this apron the damp malt travels over the n pper tier of steam-heating pipes G, and a portion of the moisture vaporized therefrom, and is regularly delivered from the right end of this apron O to the apron next below, when it is further heated over the tier of steam-heating pipes in this apron and then delivered to the apron next below, where it travels over the tier of steam-heating-pipes in this apron and is finally delivered to the lowermost apron G in the machine, upon which it is completely dried.

Any desired number of wire-cloth aprons C may be used, but I have shown four only to illustrate the general arrangement of 'my improved apparatus.

The foraminous nature of the endless traveling aprons is very important in that the heat from the pipes is permitted to pass upward through the meshes of the wire-cloth into direct contact with the malt carried thereby, thus largely increasing the efficiency of the machine.

The width and length of the aprons C will depend upon the amount of malt to be dried in a given time, and the speed at which the aprons will travel will be adapted to the number and.length and width of the aprons to cause the malt to be completely dried before it leaves the lowermost apron.

Having thus described my invention, what I claim is In a malt-drying machine, the combination of a series of drums, B, the series ot'foraminons aprons alternately traveling in opposite directions, the spur-wheels F, connecting the shafts of the drums at one end of the machine, the hopper J, the agitator J, and the link-chain J connecting the shaft of the agitator with the upper drumshaft, substantially as described.

In testimony whereof I have signed my name to the foregoing specification in the presence of two subscribing witnesses.

ADAM SCHULTZ.
