"Application filed May E9, 18S3. (No model.) Paifuted in England Ocioher24,1EE2, No.5,067.

Y ing date October 24,1882,No. 5,067,) of which the following is a specication.

p tion of the hopper, so that a hops, so that the said hops may be The object of this invention is the utiliza tion of the waste material known as spent used again, and the hitters, &c., contained therein utilized, a great saving being thereby effected.

The said invention will be best understood by reference to the accompanying drawings, in which Figure 1 is a front elevation of the machine, Fig. 2, a back elevation. Fig. 2 is a back elevation, showing the fan for exhausting the fumes from the drying or heating chamber; Fig. 3, a plan. Fig. 3 is a ver tical section of the hopper to more clearly show the operation; Fig. 4, a longitudinal section of the dryingcylinder, with a long Bunsen burner underneath; and Fig. 5, a longitudinal section of the separating-cylinder.

The apparatus will be best understood from the plan, Fig. 3.

A is Ithe dryingcylinder on the line x y, Fig. 3; and B, the separating-cylinder. C is a hopper, across which are two slowly-revolving shafts, C. and C2, having arms or equivato separate the hops and keep them from forming into lumps or balls;

A grating is placed across the hopper just over the top shaft,-and upon this the hops are placed. The arms C, in revolving, come up through the spaces in the grating between the bars, and as said arms descend they draw in with them some of the hops to the lower porregular feed is 4the result, instead of the hops falling in in a lump, as would be the case if thisjor a similar one were not employed. This is shown in Figs. l and 3, where I? is the grating.

A spout, D, leads from the side of the hopper, at the bottoni, into the drying-cylinder A, and a sliding door or panel, D', arranged within the hopper, is held back by a spring or equivalen t, D2, leaving the passage open, while a central arm upon shaft C2 is so placed as to catch this slide and move it against the spring as it passes.` As soon as the door is free from the arm itiiies back under the influence ofthe spring D2, and so shakesthe hops forward and downward into the cylinder A.

An adjustable door or slide, D, in the side of the hopper is set open at the proper distance to supply the hopsat the desiredspeed to the cylinder A.- Upon the shaft A of the cylinder A are wings or beaters A2 spirally arranged, so as to stir up and gradually push the hops along toward the far end of the cylinder A, whence they are conveyed in any conwvenient manner to the separatingcylinder B.

The cylinder A is heated in any required manner, a Bunsen burner, E, being shown in 4 the drawings, and I nd this to answer well.

vAn elevator, F, Figs. 2 and 3, which is located to the rear end of the machine,` and which communicates with both the drying and separating cylinders, carries the hops as they leave the rear end of cylinder A to the rear end of cylinder B, which they traverse in the opposite direction to that in A, and come out at thefront of the machine, near the hopper, where they first entered.

The shafts C and C2 are driven from a pul; ley on shaft A/ by a4 cord or equivalent, C", and it may be added that all the shafts revolve slowly. The apparatus is driven by a pulley or handle upon whichever of the main shafts is most convenient, and the various shafts are driven from one another by pulleys and belts, as shown in the drawings, or by gearing; but belts are most convenient.

A rod, G, upon a pin G', fixed in the end of the cylinderA, has its other end connected by a pin, G2, with a disk, g, upon the shaft G3, so that as G3 revolves an oscillating motion is imparted to the cylinder A, which helps to dislodge and break up the hops within. The end ofthe cylinder is closed in any convenient manner, so asto keep in the heat and smell, and a Ventilating-tube, H, leads from cylinder A to the openair, or to a chimney, so as to conduct away the fumes given oif during the drying process, and,where desired, an exhaust-fan, I, may be connected with this, so as to draw off the fumes more rapidly. Cylinder B has also its shaft B with arms or beaters B2 set in the opposite direction to those of cylinder A, so

that the hops are carried back again to the same end'of the machine that they started from.

The frame-work may be made of any suitable material, such as cast-iron; but the most suitable I find to be wrought-iron tubing, joined by couplings, elbows, 850., like gaspipng. This is the kind of framework shown in the drawings, and I find it economical, light, and very strong, and easily put together. It is of course applicable to other kinds of machines besides those described in this specification.

I claiml. In an apparatus for drying or recovering spent hops, the horizontal cylinders A B, arranged in the same plane, having shafts provided with arms set in opposite directions, in combination with means for receiving thematerial from the drying-chamber and elevating the same, whereby it is discharged into the separating-cylinder, substantially as described.

2. The cylinder A, heated as described, and having central revolving shaft,4 A', carrying beaters A2, in combination with rod G and the disk carried by the revolving shaft G3, substantially for the purpose set forth.

3. In combination with cylinder A and spout D, the hopper provided with the upper and lower shafts and grating,as described, and having the sliding panel D and spring D2, said lower shaft having the arm for operating the panel, substantially as set fort-h.

4. In combination with the drying-cylinder and spout D, the hopper provided vwith the shafts and grating, as described, and having the sliding panel D', spring D2, and adj ustable door D, substantially as set forth.

5. In combination with cylinder A, the hopper C, provided with shafts C and C2, and wings or knives G3, and grating P, substan- 4o tially as and for the purpose set forth and shown.

6. In an apparatus for treating spent hops, the combination, with the drying-cylinder A, of an exhaust-fan for removing the fumes, 45' substantially as described. l

In witness whereof I, the said EDWARD DA- vriss, have hereunto set my hand in the presence of two subscribing witnesses.
