CANE-MILL.

SPECIFICATION forming part of Letters Patent No. 794,722,

dated July 18, 1905.

Application filed September 3,1904:- Serial No. 223,225-

To all] whom it may OOH/(36TH:

Be it known that I, GEORGE M. LEAR, a citizen of the United States, residing at Donaldsonville, in the-parish of Ascension and State of Louisiana, have invented certain new and useful Improvements in Cane-Mills, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to mills for grinding sugar-cane; and the object thereof is to provide improved means for adjusting the turnplate with reference to the cane-roller, so as to facilitate the operation of the mill and the cleaning thereof, a further objectbeing to'provide a turn-plate of improved construction; and with these and other objects in view the invention consists in the construction, combination, and arrangement of parts hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanyingdrawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which- Figure 1 is an end view of a mill made according to my invention; Fig. 2, a partial section on the line 2 2 of Fig. 1; Fig. 3, a section of the turn-plate on the line 3 3 of Fig. 6; Fig. 4:, a plan view of the bottom portion of the turn-plate; Fig. 5, a bottom plan view of the top portion of the turn-plate; Fig. 6, a transverse section of the turn-plate on the line 6 6 of Fig. 3; Fig. 7, a sectional view of one of the supports of the turn-plate, and Fig. 8 a plan view thereof.

In the drawings forming part of this specification I have shown the main frame and main parts of an ordinary cane-mill such as is now used for grinding cane for the purpose of making sugar and molasses, and this mill comprises a main frame composed of end members a, which may be rigidly connected in any desired manner or bolted to a suitable fountain in the usual Way.

Mounted in the main frame or between the end members thereof are the usual rollers Z), c, and d, the roller 72 being called the top roller, the roller 0 the cane-roller, and the roller (Z the bagasse-roller.

Running longitudinally of the mill and between the rollers 0 and OZ is the turn-plate e, which in my improvement is supported by end arms f, arranged approximately at an angle of forty-five degrees between the rollers Z) and (Z and at the ends thereof.

The arms f are provided at their lower ends with keepers f forming angular sockets, and the turn-plate e is provided with end members x, which pass through said sockets. 'The upper ends of the arms f are formed into screws, as shown at f and secured to the end members a of the main frame of the mill, at the back thereof, and between the rollers b and (Z are keeper-plates g, having ears g and mounted in the ears g are journals 7L, pro vided with heads ]L2, to which the screws f of the arms f pass, and above and below the heads 71/ of the journals h are placed nuts c'. The screw portions f of the arms f pass loosely through the heads k of the journals h, and the position of said arms in said heads and the position of the turn-plate 6 may be easily adjusted by the manipulation of the nuts '5, as will be readily understood, and the turn-plate 6 may be moved from the roller 0 or toward said roller, as may be desired.

The turn-plate e is divided longitudinally into two parts a bottom part 0 and a top part e and the bottom part 6 is provided at one side with a raised tongue 0 and at the other side with a countersunk groove 6 while the top part is provided at one side and in the bottom thereof with a groove 6 adapted to receive the tongue 6 at the top of the part 0 and at the opposite side with a tongue 0 adapted to enter the groove 0 in the part 0 and said parts may be connected by moving the top part a transversely over the bottom part 6 The bottom part 0 is also provided in the bottom surface thereof with an angular recess 6 and the top part 6 is provided on the bottom surface thereof with an angular lug or projection 6, adapted to enter said recess when the separate parts 0 and e are connected. The bottom part 6 is projected at both ends, so as to form end members as,

which pass through the keepers f at the lower ends of the arms f, and in the top portion of one of said end members is a longitudinal groove 7', at the inner end of which is a deep angular recess f and placed in the groove 7' is a screw is, the head of which fits in and is movable in the recess and the outer end of the screw in is angular in form, as shown at 73 and said screw may be turned by a wrench or other device. The head 70 of the screw 76 projects beyond the bottom part 6 of the turn-plate, and the top part a of said turn-plate is provided in the bottom thereof with a recess m, adapted to receive part of the head 70 of the screw is, and mounted on the screw fi is a nut m which fits in a corresponding recess in the end member a: of the bottom part c of the turn-plate in which the screw 70 is placed, and when the parts 0 and e of the turn-plate have been connected by moving one transversely of the other, so that the lug or projection 0 will enter the annular recess 0 the said parts may be locked together by turning the screw k which will force the lug or projection 0 into the longitudinal portion of the recess 6 l With my improvement the turn-plate is not so apt to be broken or bent as with the old construction, and if by accident the same oc curs the separate parts thereof may be more easily disconnected; but by connecting the separate parts as shown and described the tongue-and-groove connection at the opposite sides and the lock for holding the parts together make the entire turn-plate substantially of one piece, the strength of each being added to the other, and if an accident occurs the separate parts of the turn-plate may be disconnected more easily than with the construction heretofore employed.

By employing the armsffor supporting the turn-plate and providing means whereby the latter may be adjusted toward and from the roller 0 I. also provide means whereby the mill may be more easily and quickly cleaned than with other devices of this class as heretofore constructed, and the operation of the mill is in this way facilitated and made more efiectual without any appreciable increase in the cost of the construction thereof.

The journals it, through the heads if of which the screw portionsf of the armsfpass, are provided between the ears with collars k which prevent the lateral movement of said journals and permit them to turn freely in the bearings formed by the ears 9 The end housings or members a of the main frame are provided centrally with openings n, in the bottoms of which are placed steel blocks or similar supports m and the end members a: of the bottom portion 6 of the turn-plate are projected so as to rest on these blocks; but my invention is not limited to this particular arrangement, and any other support for the turn-plate may be provided, the object of the arms f being to adjust said turn-plate with reference to the roller 0 or move said turnplate as may be desired in the-operation of the mill and in the cleaning thereof when necessary.

It will be understood that, independent of the construction herein described and claimed, the operation of the mill is the same as that of other mills of this class, and changesin and modifications of the construction herein described may be made without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, what 1 claim as new, and desire to secure by Letters Patent, is 1. A canemill provided with the usual rollers, and a turn-plate located between the bottom rollers, said turn-plate being provided at the ends thereof with arms which project upwardly and backwardly and which are adapted to swing in a vertical plane, and means for adjusting said arms longitudinally, substantially as shown and described.

2. A cane-mill provided with the usual top and bottom rollers, a turn-plate mounted between the bottom rollers, brackets secured to the back top portion of the frame of the mill, and arms connected with said brackets and with the ends of the turn-plate, said arms being adjustable longitudinally, substantially as shown and described.

3. A cane-mill provided with the usual top and bottom rollers, a turn-plate mounted between the bottom rollers, brackets secured to the back top portion of the frame of the mill and arms connected with said brackets and with the ends of the turn-plate, said arms being adjustable longitudinally and adapted to swing in a vertical plane, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of the subscribing witnesses, this 8th day of August, 1904.

GEORGE M. LEAR. Witnesses:
