FEED. CUTTER Filed Dec. 31. 1928 Inventor I LW/70 Zwan/ih Patented May 5, 1931 UNITED STATES THOMAS F. LANNON, OF 'VAN NUYS, CALIFORNIA FEED CUTTER Application filed December 31, 1928.

This invention appertains to improvements in devices for cutting feed, particularly green feed, and has among its Vmore important objects the provision of means for imparting rotary motion to the crushing rolls and simultaneously inversing the di- Y rectio-n of rotation with respect to each other; the provision of a device of thisV character wherein one of the crushing rolls may automatically adjust itself with respect to the other to prevent damage to either of the two rolls when a rock or some solid object is fed thereto. Furthermore, to provide a device of this character wherein the parts are simple in construction, efficient in operation, and durablein use.

These and other objects will become more apparent to the reader after considering the invention as described and claimed hereinafter.

In the drawings: p y

Figure 1 is a fragmentary top plan view of the slightly Inodied form of the mechanism. y

Figure 2 is a fragmentary side elevation of the modified form of the invention.

In Figure 1 of the drawings, is shown a conventional support A and the trough B. Bearings 1-1 ournally support a shaft 2 30A at one end of which a bevelledY gear 3 is keyed. The opposite end 'of the shaft2 carries a pulley l1.

a stub shaft 6 is in mesh with the gear 3',

whereby the annular structure 9 carrying r the cutter blade 10 is driven.

The shaft 6 projects beyond the opposite side of the annular structure 9 and carries a worm 15. Y

The worm is in driving relation with a gear 16 located on the shaft 17 extending at right angles to the shaft 6. The shaft 17 carries a sprocket over which a sprocket chain 18 is trained and in driving engagement with a sprocket wheel on the shaft 19. The shaft 19 has the lower edge roll 12 mounted thereon, while the upper roll 11 on the shaft 20 carries a sprocket 21 over which a sprocket chain 22 is trained and in driving relation with a sprocket wheel 23 199W@ @il the stub Sha-ft 24g. A Sprocket A bevelled gear 8 onl Serial No. 329,379.

chain 25 is trained over the sprocket wheels on the respective shafts 17 and 24: as clearly shown in Figure 1. The adjustable idler pulley 26 is suitably mounted for taking up the slack in the sprocket chain 22.

Thus it will be seen that the modified form of the invention embodies the same principle set out in the preferred form.

It is also to be understood that certain changes may be resorted to in the manufacture of this mechanism without departing from the spirit or scope of the invention as hereinafter claimed.

Having described the invention, what I claim as new is:

A feed cutter comprising a frame, a feed trough on the frame, a drive shaft carried by the frame at one end of the feed trough and extending transversely of the frame and feed trough, a fly wheel on one end of the shaft, and a beveled gear on the opposite end of the shaft, aV stub shaft arranged at right angles to thedrive shaft rotatably mounted on the frame at one side of the feed trough,

a beveled gear on said stub shaft meshing with the beveled gear on the drive shaft, a feed cutter-wheel secured to the stub shaft, a pair of superposed feed roller shafts arranged between the trough and feed cutter wheel, means forrdriving one of the feed roller shafts from the stub shaft, and means for driving the other feed roller shaft including a sprocket wheel on said last mentioned feed roller shaft, an idle sprocket wheel at one side of the first mentioned sprocket wheel, a lower drive sprocket wheel, a sprocket chain trained about all of said sprocket wheels.

In testimony whereof I afliX my signature.

THOMAS F. LANNON.
