SPECIFICATION forming part of Letters Patent No. 548,009, dated October 1 5, 1895.

' Application filed May 5,1894. Serial No- 5 012336. (No model.)

In all whom it may concern.-

Be it known that ELMORE W. ROSS, deceased, late a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, did invent certain new and useful Improvements in Cane-Cutters, of which the following is a specification.

Said invention relates to improvements in cutters for tropical canes, sorghum, fibers, &c., the machine being especially adapted for cutting sorghum and tropical canes into small lengths across the stalks, and thus across the cells containing the juice, which run lengthwise of the stalks or canes. It has been found that it is desirable in the manufacture of sorghum to have canes of this character cut into small lengths, whether the sugar is afterward extracted by the diffusion process or acted upon by the roller-mills for this purpose. In a machine of this character used in sugar-making the constructions should be such that the machine can run continually night and day during the summer season with only such occasional stops as are absolutely necessary to change and sharpen the knives. It is necessary, therefore, that the machine be strongly and compactly built and'be so designed and arranged as to prevent delays or breakages occasioned by choking or by the introduction of foreign matter or from other causes which would compel the machine to lie idle while such breakage was repaired.

The object of this invention is to provide in a cutter of this character a novel arrangement of the cutting or knife cylinder and the driving mechanism whereby the knife-cylinder may be readily removed from the machine and be replaced by another cylinder when the cutting-knives become dull.

The further object of this invention is to provide, in combination with the removable cylinder and the driving mechanism, a yielding coupling, which will permit the knife-cylinder to stopindependent of the driving mechanism, and thus prevent breakages by the introduction of foreign substances or from other causes.

. The further object of this invention is to provide a novel arrangement of the driving and feeding mechanism in connection with the detachable knife-cylinders and knives.

The further object of this invention is to provide novel arrangements of the feeding mechanism, together with supplemental rolls for feeding the cane uniformly to the cuttingcylinder.

The further object of this invention is to provide a novel arrangement of parts by which the feeding-rolls and the supplemental rolls forming the feeding mechanism are adapted to yield or move independently at each end to accommodate varying. sizes and quantities of cane or. other material.

The further object of this invention is to provide a novel arrangement of the cutting blades on the cutting-cylinder to prevent the canesfrom being forced diagonally across the line of cut and to prevent end strain on the cutting-cylinder shaft.

The further object of this invention is to provide means for preventing an end movement of the cylinder-shaft and the detachment of the yielding coupling.

These objects are attained by the constructions set forth in the accompanying drawings, in which- Figure 1 is a plan view of a machine embodying the invention. Fig. 2 is a partial sectional view showing one side of the hopper and the arrangement of the driving and feeding mechanisms and the means of communicating power thereto. Fig. 2 is a detail of the clutch. Fig. 3 is an end view showing the opposite side of the hopper and its mechanisms. Figs. 4 and 5 are respectively a plan and side view of the vibrating arm or bearings in detail, hereinafter referred to. Fig. 6 is a longitudinal sectional view taken on the line of the main and cylinder shafts. Fig. 7 is a transverse sectional view taken through the hopper and feed-rolls. Fig. 8 is a partial side view of the knife-cylinder. Fig. 9 is an end view of the same. Fig. 10 is aside elevation view of the cylinder and cylinder-shaft. Figs. 11 and 12 are respectively an elevation and side view ofa modification in the form of a knife-head and in the arrangement of the knives thereon to form a knife-cylinder. Figs. 13 and 14 are detail views of parts of the same. Figs. 15 and 16 are detail views showing the arrangement of the pivoted rocking bearings for the supplemental feed-rolls and the slotted frame-openings through which the roll-shafts operate. Fig. 17 is a detail view in section of the detachable frictionclutch on an enlarged scale.

Like parts are represented by similar letters of reference in the several views.

The machine herein set forth is of that style which is known as the inclined force-feed in distinction from those machines characterized bya level bed with an automatic carrier-feed, the hopper and feeding mechanism being in this case placed in a plane at an angle to the horizontal and inclined downwardly toward the cutting-cylinder.

In the said drawings, A A represent the main frame or bed-plate of the machine, on which the operating parts are supported. B is the main driving-shaft supported in suitable bearings a a on said bed-plate or frame, said bearings being provided with removable caps or covers to permit a ready removal of the knife-cylinder, as hereinafter specified. That portion of the frame A above and in front of said bearings is also hinged at A as shown in Fig. 7, to permit ready access to the knife-cylinder and its bearings for the purpose of removal or otherwise. 13' B are pulleys on said main frame, on which the driving-belt runs to supply the power to the machine, one of said pulleys being connected rigidly to the shaft and the other adapted to turn loosely thereon, forming tight and loose pulleys in the ordinary manner.

13 is a fiy-wheel, which is preferably arranged and constructed as shown in Patent No. 255,196, granted to said ELMORE W. ROSS, but, if desired, may be secured rigidly to the shaft B in the ordinary manner.

0 is a knife-cylinder mounted on the shaft C, adapted to turn in suitable bearings a a at each end thereof and in line with the main shaft B. The knife-cylinder O is composed of a series of cutting blades or knives b, supported upon suitable knife-heads d on the shaft C. The cylinder O is adapted to be revolved in the direction of the arrow in Fig. 7, so as to bring the knives or blades 12 in close proximity to a stationarycutter-bar D, which extends transversely across the lower part of the hopper just back of the feeding-rolls in what is termed the throat of the machine.

In a machine of thischaracter it is necessary that the knives cut across the entire length of the cutting-bar, which is quite long in the ordiuary-sized machines. It is also desirable that the knives or blades be placed spirally about the cylinder in order that a shearing cut may be secured. When thus arranged, a heavy pushing or crowding of the canes in the direction of the shear of the knives and a corresponding thrust of the knife-cylinder in the opposite direction are experienced, which results in forcing the canes to feed diagonally across the fixed cuttingplate, thus producing a long diagonal cut instead of a square cut, and at the same time by the heavy thrust upon the knife-cylinder inder.

causing a wear upon the ends of the bearings and knife-head hubs. To overcome these difficulties, the knife-cylinder is formed in sections, and the blades forming the respective sections spirally about the same cylinder are arranged in such a manner that the shear of the knives in one section is in the opposite direction from the shear of the knives in the other section, so that the inclination of one set of knives to press the material and the knife-cylinder in one direction is overcome by the opposite shear in the other set of knives. The knives are preferably arranged, as shown in Fig. 10, so that the knife-sections at each end of the cylinder incline toward the center. The knives are also arranged in one section slightly in advance of the corresponding knives in the other section. The arrangement of the knives in sections, with the knives in one section in advance of those in the other section, relieves the cylinder momentarily from a long continuous cut, thus using the power more uniformly than when a single long knife is used.

As before stated, the knives are supported upon knife-heads (1. It has been the common practice to secure the knives directly to the heads by means of bolts extending through said knives and connected to theknife-heads. In order that the knives may travel in the proper circle as the cylinder is revolved, they are made in the are of a circle in cross-section. They are also arranged spirally about the cyllVhen thus constructed considerable difficulty has been experienced in adjusting the knives, since a movement ofone end of the knife greater or less than at the other end of the knife at once detaches it from its firm seat by changing the angle of the knife, and thus preventing a greater or less circle to the bear ing or seat than that uponwhieh it was originally formed and tempered. In this machine, in connection with the knife-heads d, are used small saddle-plates c, on which the knives rest. These saddle-plates are each formed on their upper edge to conform to the circle of the knife-blade and are provided at the rear with upwardly-projecting flanges 0, adapted to come squarely against the back of the knife and retain at all times the same relative position with said knife. These saddle-plates are rested on inclined bearing-faces e on the knifeheads d and are secured thereto by fasteningbolts 6, which pass through said knives and saddle-plates and through the bearing-supports e, which are preferably formed in the nature of a flange on said knife-heads d. The hole through which the fastening bolt e passes is made slightly slotted or larger than the bolt 6, so that an adjustment of the saddle and the knife thereon may be secured by loosening said bolt. Immediately behind each of the saddle-plates and adapted to rest in contact therewith is an adjusting-screw 6 which screws into a projecting flange or boss formed on the knife-head, the said screw 6 being screwed into said boss or projection ITO from the side on which the saddle-plate is located, the head of the said screw resting against the saddle-plate. A j am-nut e is also provided, adapted to be tightened against the boss or projection e and thus hold'said screw firmly therein. By this construction the knife may be readily adjusted forward or backward, and as the end of the knife is adjusted the back edge of the knife, resting against the flange of the saddle-plate, twists the said saddle-plate around with it, always retaining, therefore, the same solid seat for the knife, so that no rocking of the knife can occur, or can the knife be twisted out of its original and correct form by tightening the fasteningbolt 6'.

In the modifications shown in Figs. 11 to 14, inclusive, the inclined seats or bearing-faces e, on which the saddles 0 rest, are made in the nature of separate blocks adapted to rest on the peripheral flanges e on the knife-head, the knife-head being provided with small projecting lugs e against which the bearing blocks 6 rest to prevent said bearing-blocks from being forced longitudinally as the saddle is moved along the inclined faces. In Fig. 11 is shown one of the knives and saddles pushed up along the inclined bearingseat to show the rapid adjustment secured by this construction. It will be noted that by this construction and as indicated by dotted lines in said view, as the knives are forced outwardly the clearance at the back of the knife is increased. As before stated, the cylindershaft 0 and the main shaft B are located in the same horizontal line. These shafts in the present machine are connected together by a yielding coupling E, the outer portion E of which is secured to the main shaft B and the inner portion E secured to the cylinder-shaft C. The outer portion E is preferably secured to the shaft B upon a spline or feather-key f so that it turns readily with said shaft, but is capable of a longitudinal movement thereon. The other or inner portion E is secured rigidly to the cylinder-shaft O. The outer portion E of the coupling is formed in the nature of a casing adapted to receive'the inner portion E The inner portion E is turned off on its periphery and fits loosely in said casing. This outer casing is provided with pockets g, preferably three in number, adapted to receive bearing blocks g, which are adapted to be moved to or from the part E by set-screws g passing into said pockets. Located about the inner portion E is a fastening-ring E provided with bearing-faces 77., adapted to rest on the hub of the part E and having projecting ears h to receive fasteningbolts 7L which are provided at one end with eyes 71 adapted to receive pins 7L5, which secure them to projecting ears h on the outer portion E of the coupling. By this construction the parts of the coupling are held firmly together. By loosening the bolts hi however, the said bolts may be thrown back out of the ears h of the fastening-ring E permitting the saidring to. be removed and the outer portion E of the clutch to be withdrawn from the inner portion, thus readily uncoupling the shafts to permit the knife-cylinder to be removed. The bearing-blocks are made of any suitable material and are adapted to be forced against the inner portion E of the coupling to produce any desired amount of friction between the parts to cause the knifecylinder to revolve with the main shaft, but at the same time to form a yielding connection which will permit the knife-cylinder to be retarded or. to stop suddenly whilethe driving mechanism continues to revolve, this being accomplished by the slipping of the bearing-blocks upon the periphery of the inner part of the coupling.

Immediately in front of the cutting-bar and the knife-cylinder in the hopper are the feeding-rolls F F, one of which is provided with yielding bearings and adapted to move to or from the other stationary roll, as more or less material is fed between the same, in anyusual or weltknown manner. In order to provide for driving the feeding-rolls and the other portions of the feeding mechanisms, as hereinafter described, without interfering with the detachable cylinder, a counter-shaft G is provided, supported in suitable bearings i on the main frame, and connected to the main shaft at its outer endwith a suitable sprocket or other gear G and at the other end by a spur-pinion and gear G2 G to the stationary feeding-roll F.

F F F and F are the supplemental rolls which are located in the hopper in front of the feeding-rolls F F. These rolls are arranged in pairs, two pairs being shown in the drawings, though a greater or less number may be used, if desired. Each pair is ar-,

ranged closer together than the next preceding pair, so that a converging throatis formed up to the feeding-rolls and knife-cylinder. The journals of the lower supplemental rolls F F of each pair pass through slotted openings F F in the frame, (see Fig. 15,) and are supported at each end by vibrating arms H,

adapted to permit of an independent moves.

ment at each end of said rolls tooompensate for Varying quantities of material fed thereby. These vibrating arms H are each pivoted to a transverse shaft H, which extends transversely through the hopper and conveys the power to drive the rolls from onerend of the machine to the other, as hereinafter set forth. The power to drive the upper supplemental rolls F and F of each pair is communicated from aspur-gearj on the shaft of the feedingroll F through an intermediate spur-gear j to a spur-gear 7' on the shaft of the supplemental roll F from this through an intermediate gearj to a spur-gearj on the shaft of the supplemental roll F. From the spurgearj through the medium of an intermediate gearj and its pinion j, power is transferred to the shaft H; from the shaft H to the lower supplemental roll F on the opposite side of the hopper by a spur-gearj operating into a similar gearj thence from the supplemental roll F to the supplemental roll F by a chain and sprocket-gearj. By the construction thus described and by the use of the intermediate gears of proper relative sizes a uniform peripheral speed of the supplemental and feed rolls is secured, while at the same time the rolls are arranged converging, as described, and the rolls of the respective pairs adapted to be separated to compensate for varying quantities of the material. The vibrating arms H, in which the bearings for the lower supplemental rolls are located, are each provided with an end bearing for the shaft H. The bearings proper 70' for the roll-shat ts are each provided with trunnions k adapted to rest in suitable bearings 76 in said arms, so that a rocking motion of the shafts is permitted, to allow one end of the supplemental rolls to move up or down independent of the other end. Springs k serve to hold the supplemental rolls and the vibrating arms in their normal positions,but permit them to yield to accommodate the material.

In order to guard against longitudinal movement of the cylinder-shaft O and to insure the parts of the coupling E from being disconnected and to prevent strain upon the respective parts, the end of said shaft 0' is provided with a steel toe Z, adapted to run in a hearing or step Z in a bracket I, secured to the main frame A A, a set-screw Z being provided to adjust the said hearing or step against the end of the said toe. The bearing 1 for the toe Z is adapted to set loosely in the bracket I, so that when the set-screw is loosened and the coupling disconnected the cylinder may be readily removed from its.

bearings.

Power to drive the lower feeding-roll E is transmitted from the upper feeding-roll F through the medium of a spur-gear J and a round-face gear J, hungin a vibrating bearing and connected with a universal joint in the manner described and claimed in said EL- MORE 'W. Ross former patents, Nos. 254,843 and 275,861.

The operation of the machine as thus described it is thought will be understood from the above description. The canes are fed to the supplemental rolls by means of an endless carrier or in any other desired manner, the discharge end of said carrier or conveyer being preferably located considerably above the hopper of the cutter, so that the material will be conveyed by gravitation through a chute into the hopper of the machine, the rolls and working parts of the machinebeing placed at about the same angle as the incline of the chute, thus avoiding the necessity of an extra carrier between the cane-carrier and the throat of the machine. The canes are drawn in by the supplemental rolls and gradually forced together until they meet the feeding-rolls, whence they are drawn into the knife-cylinder and are out between theknives of said cylinder and the stationary cutter-bar, from whence they are discharged into asuitable receptacle or carried away by an elevator or carrier, as indicated at L in Fig. 3.

The bed-plate A A is extended underneath the several parts of the cutter, which are secured in rigid frames and bearings to said bed-plate in order to prevent any of these several parts getting out of alignment. As the two sections of the main shaft B and G are intended to be in exact alignment, and one end of the shaft 0 being inserted within the recess in the movable casing'E on the shaft B, the slightest settling of any part of the machine would prevent the coupling from holding the two shafts B and 0 together and defeat and destroy the practical workings of the parts at this point, the solid frame, therefore, being intended to obviate the trouble occasioned by the settling of its foundation or the building in which it is located, as every part of the machine would retain its proper relation to the other parts, although the bedplate would settle.

By the arrangement of the detachable knifecylinder in connection with the main shaft and yielding coupling the knife cylinder may be readily removed and be replaced by another with sharpened knives, the change occupying but a few minutes. The knives on the cylinder may be taken off and resharpened and be readily set to their position in readiness to be replaced on the machine when the knives on the other cylinder become dull. By this arrangement a probable breakage from foreign substances entering the knife-cylinder or from other reasons is also obviated, as by the yielding coupling the knife-cylinder may be permitted to come to a stop without any damage other than perhaps the nicking of the knives where the foreign matter was struck.

By the arrangement of the counter-shaft and feed-gear the feed mechanism is left undisturbed when the knife-cylinder is removed. By the feed-gear as described a uniform peripheral motion is imparted to the supplemental rolls and the feeding-rolls. By the use of one or more pairs of supplemental rolls a continuous feed of the machine is secured and the liability of choking by crooked canes or varying quantities of material is obviated.

By means of the vibrating arms and rocking bearings thereon for supporting the supplemental rolls one end of said rolls is permitted to drop down more than the other and thus compensate for a varying quantity of material on one side of the machine.

By the arrangement of the too or step on one end of the shaft the danger of separation of the parts of the coupling and the wear on the knife-cylinder are reduced.

In the end of the shaft 0 and, if desired, at each end of the knife-cylinder is provided a groove an, adapted to receive a hook or rope forming part of the sling by which the knifecylinder is raised from its position in replacing the cylinder. This groove m prevents the hook or rope from sliding olf from the end of said shaft and retains the same in position, thus obviatingthe liability of slippages and breakages resulting therefrom.

The machine as above described is especially adapted for use in su gar-making, though its utility is by no means confined to the cutting of cane. It is obvious, however, that it may be used for cutting any material for which it is adaptedsuch, for instance, for cutting fibers of various kinds in the manufacture of paper and for other purposes.

By the arrangement of the knife-heads and saddles, together with their adjusting-screws, means are provided by which the knives may be readily adjusted without straining a knife or putting it in afalse position. The adjusting-screws, being screwed into their supporting bosses or bearings from the side on which the knife or saddle is located and each provided witha head between the said knife and bearing or boss, are held positively against displacement and cannot become loosened and drop into the cylinder-knives or into the other parts of the machinery, as not infrequently happens with other arrangements of the adjusting parts.
