IMPROVEMENT IN SUGAR-MILLS.

Speeilieation forming part of Letters Patent No. 41,265, dated January 12, 1364; antcdatcd December 10, 1863.

To all whom; it may concern:

Be it known that I, LUTHER E. PORTER, of Lake Mills, in the county of Jefferson and State of Wisconsin, have invented certain new and useful Improvements in Sugar-Mills; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and the letters and iigures marked thereon, which form part of this specification.

In said drawings, Figure l represents aside View of my invention. Figs. 2 and 3 are rcspectively a longitudinal and cross section of the 'sliding fulcrum G. Fig. Lt is afront and top view of the loop c, and Fig. 5 is a view of the lower side of the lever E.

Similar letters in the diiierent figures indicate corresponding parts of my invent-ion.

The nature of my invention consists in a novel inode of adjusting the crushing-rollers of a sugar-mill by means of a lever operating upon sliding journal-boxes sul'lporting the rollers, so that the pressure of said rollers upon the cane is equal throughout the entire length ofthe cane, notwithstanding the const-ant variation in the size thereof.

To enable others skilled in the art to understand how to construct and use my invention, I will proceed to describe the same with pariicularity, reference being made to the drawings. l

InA Fig. l, I-I II represent the end frame, which supports the crushing-rollers, of which there are three, arranged horizontally in the positions i ndicated by the dotted circles marked A B O. The position of the rollers B O between which 'the cane is fed oigput into the mill, is iixed; but the journals of the-roller marked A a av are supported in a sliding box, (marked D,) which istted in a groove in the end frames, running toward thevcenter of the roller C, so that the said roller A can movetoward or recede from the roller C, as may be desired. The said rollerA is'kept in position by means of the lever E, operating upon the adjustable journal-box D, as shown, resting upon the fulcrum G, which 1s adjustable longr tudinally upon the shoulder H by means of the screw s and the nut a, or in any other suit'- able manner.

d represents a small ball, which serves as a bearing between the lever E-.and the sliding box D, and Amaybe adjusted at diiferent polnts nPQil said lever, so that, 1n connection with the sliding fulcrum Ur, the short'arm of said lever may be varied in length., as may be desired. A weight, IV, is attached to the long arm of the lever E, of such weight and at such point thereupon as to cause the proper amount of pressure upon the sliding box l); or an ach ditional lever, F. may be employed in combination with the lever E, as shown; or, if a still greater pressure should be desirable, the lever F may be arranged as shown by the dotted lines, by employing a loop, Fig. 4, of sufeient length. In the drawings thearrange'mcnt is shown only at one end of the roller A; but the same device, arranged in the same manner, is employed at each end of the roller, and, being duplicates, only one view is shown.

The operation of my invention is as follows: The weights W being suspended upon the levers E, the roller A is pressed up against the roller C. The cane is put into the mill between the rollers B G, as indicated bythe red arrows, which are at such a distance apart as to break and partially crush the cane, which passes along and enters between the rollers A O, which press closely upon the cane and extract the juice, the pressure being equal throughout the entire length and varied diameter of the cane by means of the operation ot the le'ver and' weight, as described. Instead of operating said lever by means of a weight, as shown, a spring or other mechanical device maybe employed, though I deem the employment of weights the cheapest and simplest method.

I do'not confine myself to the particular arrangement oi the levers shown and described, the material point being that the -sliling box shall be adjusted by a lever provided with a suitable fulcrum, and operated by any power properly applied.

Vhat I vdo claim as my invention, and desire to seeurelby Letters Patent, is-

1. The combination and arrangement of the roller A, the adjustable journal-box D, with a lever or combination of levers, operating substantiall y as and for the purposes herein specied and shown.

2. In combination with said adjustable box and levers, the employment of the sliding fulcrunn G, arranged and operating as and for the purposes herein shown and described.
