SPECIFICATION forming part of Letters Patent No. '757,988,dated April 19, 1904. Application filed July 3, 1903. Serial No. 164,179. (No model.)

To all whom it may concern:

Be it known that we, HENRY WILsoN and HENRY L. CRUMBLY, citizens of the United States, residing at Richland, in the county of Stewart and State of Georgia, have invented certain new and useful Improvements in Sugar-(Jane Crushers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to improvements in mills for grinding sugar-cane, sorghum, or the like, and it is more especially intended for small mills, which may be put up without the expensive foundations required in the larger plants and which may be operated either by hand power, by machinery, or by horsepower.

Our invention will be understood by reference to the accompanying drawings, in which the same parts are indicated by the same letters throughout both views.

Figure 1 is an end view, parts being broken away; and Fig. 2 is a section on the line 2 2 of Fig. 1 and looking in the direction of the arrows. M

The shafts of the four rollers C, C, (J and G are journaled in journal-boxes in the housing, which is comprisedof two plates A and A, provided with lugs a and a and connected together by the bolts B and B, passing through said lugs. The opposite lugs a are separated by washers 5, while the lugs 60 are separated by a stiff coil-spring B as seen in Fig. 2. To ease the strain on the back rollers C and O cup-springs B may be mounted beneath the nut b on the bolt B, as seen to the right of Fig. 2. Also the mill may be adjusted by easing up or screwing down on the nut on the bolt B.

The two plates A and A are preferably provided with interpenetrating arms a a, (0*, and a to prevent the cane or bagasse from passing out laterally and fouling the gearing.

Across the front of the mill the guard-plate D is mounted, which is secured on the tiebolts E by means of the slotted lugs (Z. This guard-plate has a V-shaped piece D projecting inward from its sides, which piece projects into the space between the rollers C and C, as shown in Fig. 2, while the top and bottom of the plate is cut away and bent in, as at D and sharpened to form scrapers and also guards for the rollers. Thus it will be seen that the two side pieces 1) and the top and bottom pieces D of the plate D form a sort of funnel into whichthe cane or sorghum is fed.

Scrapers D are provided at the back of the mill, which clean the rollers of the bagasse and cause the same to be delivered behind the mill. These scrapers are mounted on the tiebolts E, spanning the back of the mill and are generally similar to the tie-bolts E. The scrapers D may be adjusted by means of clamp-bolts or screws 6.

It represents a perforated turn-plate, which is mounted between the lower rollers and prevents the bagasse from dropping down between the same. The rollers turn in the direction indicated by the arrows.

F represents a combined bed plate and trough at the bottom of the mill, into which the expressed juice falls and from which it is delivered through the spout f. This combined bed-plate and trough is mounted on feet F above the foundation on which the mill rests, and the housing-plates A are secured thereto, as by means of bolts 0 The mill may be driven either by hand-crank K and handle K or by a belt (not shown) over the pulley I or by horse-power connected to the head L.

Where the mill is to be driven from the pulley I, the head L, with the beveled gear L fast thereto, is preferably removed from the pivot L and the handle K is'detached from the shaft H. Where it is to be driven by hand-power, the beveled gear L and head L may be preferably left off. Where it is to be driven by horse-power, the handle alone may No matter what kind of power.

be removed. be used the shaft H is turned, and the gears H and H fast thereon, turn therewith. These gears mesh with the spur-gears M and P, mounted on the shafts M and P of the upper rollers C and C respectively, and thus turn these rollers; Fast on the shaft M is a second gear M which meshes with the gear N on the shaft N of the roller C, whereby this roller is caused to turn. Fast on the shaft I is a second gear'P which meshes with the gear Q, fast on the shaft Q, whereby the back roller C is turned. Thus it will be seen that the rotation of the shaft H in the proper direction causes all of the rollers to revolve and that this rotation may be produced either by the pulley I, by horse-power, or by hand.

It will be obvious that other applications of power may be used to rotate the shaft H and that the mill may be made larger or smaller, as desired. The back rollers should be mounted closer together than the front, so as to distribute the compression between the rollers, and, moreover, the back rollers should preferably be larger and with heavier shafts in order to secure better extraction of the juice.

It will be obvious that various modifications might be made in the herein-describedapparatus which could be used without departing from the-spirit of our invention.

Having thus described our invention, what we claim, and desire to secure by Letters Patent of the United States, is
