ROBERT M. DUDLEY, OF METAMORA, MICHIGAN.

BAND-CUTTER AND FEEDER.

SPECIFICATION forming part of Letters Patent No. 466,225, dated December 29, 1891.

Application filed March 9, 1891- Serial No. 384,306. :(No model.) 3

To all whom it may concern.-

Be it known that I, ROBERT M. DUDLEY, a citizen of the United States, residing at Metamora, in the county of Lapeer and State of Michigan, have invented certain new and useful Improvements in Band-Cutters and Feeders; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in a new and improved band-cutter and feeder, which is comparatively simple in its construction and very effective in its operation; and the invention will be hereinafter fully described and claimed.

Referring to the accompanying drawings, Figure 1 is a perspective view of my new and improved band-cutter and feeder. 1 Fig. 2 is an end view of the same. Fig. 3 is a central sectional view, and Fig. 4 illustrates in detail the band-cutter knife. Fig. 5 illustrates in detail, on an enlarged scale, the distributors 32 and their operating mechanism.

The same numerals of reference indicate corresponding parts in all thefigures.

Referring to the several parts by their designating-numerals, 1 indicates the main frame of the device, and 2 indicates the lower table, on which the bundle of grain is discharged after its band has been cut. Beneath this table is mounted a drive-shaft 3, having a band-wheel 4, around which passes a drivebelt from any suitable source of power, usually from a drive-shaft of the thrashing-machine to which the device is attached. On the outer end of the shaft 3 is mounted a beveled cog-wheel 5, which meshes with a similar beveled Wheel 6 on the inner end of the shaft 7, which is mounted in bearings at right angles to the shaft 3. On the outer end of the shaft '7 is mounted a pulley 8, and a belt 9 passes around this pulley and a corresponding pulley on the end of a transverse crankshaft 28. A second belt 9 passes from the pulley 8 around a pulley 10 on the front roller-shaft 12. A slatted conveyor belt or apron 11 passes around the forward and rear rollers 12 12?, passing over the main table 14, upon which the bundles are first thrown.

Upon theends of the roller-shaft 12 are the feed-belts 13 and 20 will be revolved in the 1 direction indicated by the arrows.

In operation the bundles of grain are thrown upon the table 14, when the revolving conveyer-belt 13 carries them forward beneath the frame 16, where the feed-belt 20 comes in contact with them and the bundle is carried forward by the two revolving belts or conveyers. The rear end of the pivotally-mounted frame 16 is supported by the arms 22, formed with the longitudinal slots 22 near their upper ends, through which studs 23 on the rear end of the frame pass. It will thus be seen that the rear end of the frame is allowed a certain amount of play or movement to accommodate itself to the thickness of the'bundles passing between it and the table 14.

24: indicates the long cutting-blade, the ends of which pass through slots 15 in the end plates 15 and are pivotally mounted upon the small crank-shafts 25. The ends of these crank-shafts are mounted in bearings on the end plates 15, and they have the pulleys 26 secured upon them. A cord or small band passes around these pulleys and fits in annular grooves 27 in the pulleys on the ends of the roller-shaft 12. It will be seen by this arrangement that as the roller-shaft 12 is revolved the long knife 24 will be swung down to cut the band of each bundle as the latter passes beneath it, and will then be raised to permit the out bundles to pass freely beneath it. The cut bundles fall upon the inner end of the table 2, where they are scattered and pushed forward to the packers by the following device: The'transverse shaft 28 is formed near each end with the double cranks 29. which are pivotally connected by small pitmen 30 31 with the rear edges of the distributers These distributers consist of two boards or pieces 32 32, arranged transversely to the body, which extend entirely across the end of the lower table 2, being arranged one immediately above the other and being connected to the two cranks 29 2!) by the pairs of pitmen 30 81, which are so arranged that as the lower distributer is slid forward by the revolving crank-shaft the upper one is slid back and as the lower board is drawn back the upper distributer is slid forward. The advantage of this construction and operation is that as the lower board or distributer is slid back after having pushed the loosened grain from the cut bundle forward on the table the upper distributer sliding forward over it prevents the grain which is falling from the cutting-knife from being drawn back by the re ceding distribnter and pushes the said grain forward, while the lower board is moved back. By this construction the feed of the loosened grain forward over the table 2 is much more rapid and eifective than is possible where a single feed-board is employed or where the feeder is composed of two sections arranged side by side.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-- 1. In a band-cutter and feeder, the combination, with the revolving crank-shaft formed with the double cranks 99, of the transverse upper and lower distributers 32, arranged transversely to the body, one above the other, and connected by the pitmen 3O 31 t0 the double cranks of the shaft 28, so that they will be alternately reciprocated back and forward, traveling, respectively, above and below each other, substantially as and for the purpose herein set forth.

2. In a band-cutter and feeder, the combination of the table 14, the revolving conveyer-belt 13, the frame 16, the revolving feedbelt 20, mounted on the same, the long, blade 24, the revolving crank-shafts 25, on which the ends of the blade are pivotally mounted, the revolving shaft 28, formed with the double cranks 29, the reciprocating upper and lower distributers 82, arranged transversely one above the other and operating as described, and the pitmen 3O 31, connecting the same pivotally with the cranks of the shaft 28, substantially as set forth.

In testimony whereof I ailix my signature in presence of two witnesses.

ROBERT M. DUDLEY.
