CANE MILL.

Application filed December 2, 1922. Serial No. 604,547.

To all whom t may concern.'

Be it known that I, LEE H. DILLMAN, a citizen of the United States, residing at Agra, in the county of Lincoln and State of Oklahoma, have invented certa-in new and useful Improvements in Cane Mills, of which the following is a specication, reference being had to the accompanying drawings.

T his invention relates to improvements in cane mills, and more particularly to an attachment for cane mills whereby the blades of the cane will be removed fromthe stalk as the cane is fed to the mill, thereby permitting their use as fodder.

An important object of the invention is to provide a device of this character the stripping mechanism of which is operated from the drive shaft of the mill.'

A still further object of the invention is to provide a device of this character which is simple in its construction and arrangement, durable in service, and a general improvement in the art.

-in additional object of the invention is to provide a device of this'character embodying guides whereby the stalks may be directed to the crushing rolls without the necessity of the operator coming into such close contact with the crushing rolls as to endanger him.

These and other objects l attain by the construction and arrangement shown in the accompanying drawings wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein like reference characters designate like parts throughout.

ln the drawings Figure 1 is a side elevation of a cane mill embodying the improvements of this invention;

Figure 2 is a horizontal section on the line 2-2 of Figure 1;

Figure 3 is a top plan and partial horizontal section of the invention; and

Figure a is a side elevation looking at the side opposite to Figure 1.

Referring now more particularly to the drawings, the numerals and 11 designate crushing rolls of a cane crushing mill, 12 the main shaft of the machine which drives the main crushing roll 10, and 13 means for rotating the shaft 12, disclosed in the present instance as a sweep. It is well known that the usual practice is to strip the leaves from the cane before the cane is cut and it is also the custom to feed the cane into a crushing mill. rlhese mills are of such construction that if the leaves were to'be left upon the cane and fed into the mill the leaves would be ruined for use as fodder. As a result of these conditions it is vmy aim to provide means 'in association with a grinding mill which will automatically stripioff the leaves of the cane as they areffed into. the mill, thereby making it-unnecessary to strip the leaves in the iield prior to the cutting of the cane. In accordance with my invention l provide upper and lower guides 14 which are directed above and below the rolls -10 and 11 and which are adapted for thev reception of cane stalks tobe fed through the rolls. The stalks may be pushed in at the forward end of the guides and will be guided into the rolls so as to be drawn therethrough during the crushing action.

Disposed at one side of the guides 14 is a framework 15 containing or carrying a vertical shaft 16 mounted in suitable bearings 17. To the upper end of one shaft is connected one end of a lever 18 which lever is pivoted intermediate its ends to arsuitable support, as indicated at 19. Engagement between the shaft and lever is preferably in the form of a slot and pin engagement such as shown at 20, in order that the oscillation of the lever may not place too great a strain upon the shaft. To the opposite end of the lever 18 is pivotally connected a link. 21, the upper end of which is pivotally connected, as at 22, to one end of a lever 23 pivoted upon the support intermediate its ends, as indicated at 24. The free end of Vthis lever overhangs a disk 25 secured to the shaft 12 of the mill,rwhich disk is provided upon its upper surface at spaced intervals with lobes 26 adapted to be engaged by a roller 27 carrie-d by the free end of the lever. During the rotation of the shaft 12 and accordingly the disk 25, these lobes in engaging the lever 23 will impart thereto an oscillatory movement which through the link 21 is in turn imparted to the lever 18 causing reciprocation of the frame 15. A coil spring 28 connectingv the end of the lever having a pintle slot engagement in the shaft 16 with the link 21 A tends to elevate the frame 15 and accordingly relieves in a great measure the force necessary to shift the lever 28 to elevate the frame. y

The frame 15 is provided thereon with a plurality of outstanding flexible beater members 29, the free ends of which extend into the path of canes fed longitudinally between the guides 14 so as to engage against the leaves and tear them from the stalks fed between the guides. At each engagement of the lever 23 Aby a lobe 26, the frame is elevated and upon its release by this lobe is again depressed causing these free ends to beat and strike against the stalks and remove therefrom the foliage. While I have shown and described but a single frame 15, it will be obvious that instead of simply running one of these beater frames at a single side of the guides 14, two of the beater frames may be employed, as shown in Figure 4 one at each side of these guides. As a matter of fact, this latter construction will probably result in more perfect stripping of the stalks. The lowermost beater 29 of the frame 15 will be arranged in spaced relation to the lower end of the frame in order to provide space therebeneath for the collection of the separated foliage which may be removed from time to time. The beatings to which the foliage is subjected will in no manner destroy the value of the same as fodder and at the same time large quantities of waste material is prevented from passing through the mill, thereby lessening the necessary labor in drawing the cane through the mill to a point suicient to provide for additional labor necessary to perform the stripping operation, as above described.

From the` foregoing it is believed to be obvious that an attachment constructed in accordance with my invention will materially assist in handling cane, saving the blades thereof for use as fodder and preventing the operator from becoming endangered in feeding the cane to the mill without adding materially to the necessary labor or power required to operate the mill. It will furthermore be obvious that the construction as hereinbefore set forth is capable of many changes and modifications without materially departing from the spirit of my invention and l accordingly do not limit myself to such specific structure except as hereinafter claimed.

I claim 1. The combination with a cane crushing mill embodying a pair of crushing rolls adapted to receive and crush therebetween stalks of cane, guides directed between said crushing rolls, a framework disposed at one side of said guides, means operated by the rotation of the rolls for reciprocating said frame, and beaters carried by said frame and extending adjacent said guides.

2. The combination with a cane Crusher embodying crushing rolls and a drive shaft for rotating one of said rolls, of guides directed intermediate said rolls,y a frame embodying beaters extending adjacent said guides, and means for reciprocating said frame embodying a cam disk secured to said shaft and a link and lever connection between said cam disk and said frame.

3. The combination with a cane crusher embodying the usual crushing rolls and drive shaft for the rolls, of cane receiving guides directed intermediate said rolls, a support arranged at one side of said guides.y a framework including shafts mounted in bearings carried by said support, said shafts substantially paralleling said guides, beaters carried by said framework and extending adjacent said guides, and means operated by the rotation of said drive shaft for reciprocating said framework.

ln testimony whereof I hereunto aflix my signature.

LEE H. DLLMAN.
