FRED B. DUES, OF MINSTER, (EH10.
SNAPIPING ROLL.
Application filed April 17, 1922. Serial No. 553,473.
T 0 all whom it may concern:
Be it known that I, FRED B. Duns, zen of the United States,
a citiresidlng at Minster, in the county of Auglaize and State of Ohio, have invented a new and useful Snapp e: fication.
Roll, of which the following is a speci- This invention relates to snapping rolls straightened out and rolls without spreading interfering with the snapping operation.
WVith the foregoing and other objects carried between the the rolls apart and view which will appear as the description proceeds, nation and the invention resides in the combiarrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be the spirit of the invention. In the accompanying made without departing from drawings the preferred form of the invention has been shown.
In said drawings- Figure 1 1s a view partly in section and partly in elevation of the mechanism constituting the present invention.
Figure 2 is an end elevation of one pair of snapping rolls.
Referring to the figures by characters of reference 1 designates snapping rolls arranged in pairs,
all of the rolls being of the same construction although the rolls of each pair are oppositely disposed, one being designed to rotate in a clockwise direction and the other in a counter-clockwise direction.
Each roll% is mounted shaft of one roll of each stationary bearings on a shaft 2 and the pair is supported in 3 while the shaft of the other roll of each pair is mounted in slidable bearings t. These slidable bearings are supported in guides 5 holding springs 6 which thrust against may be placed compression by screws 7. The ed in the stationary bearings 3 are provi under different degrees the bearings 4L. The springs shafts mountded and these gears, in turn, mesh 9 secured to short shafts 10. These shafts 10 are connected by universal joints 11 to those shafts mounted in the bearings 4. The outer ends of the shafts 10 are mounted in movable bearings 12 supported by a frame 13. Thus it will be seen that one roll of each pair is capable of moving away from and toward the other roll of said pair without interfering with the transmission of motion through the gears. drive wheel 14; can be connected to one of the shafts 2.
Each of the snapping rolls is provided with longitudinal series of recesses or pockets 15, each pocket having its inner wall flat and tangent to an imaginary cylinder concentric with the roll while its other longitudinal wall is radially disposed as shown at 16 in Figure 2. Both walls of each groove are extended to the periphery of the cylinder or roll. Each roll is provided at diametrically opposed points with longitudinally extending fiat faces 17 and formed within each of these flat faces is a longitudinally extending angular groove 18, these flat faces and grooves being extended throughout the len th of the rolls.
When the apparatus is in operation the stalks will be received between the rolls and the radial walls 16 of the recesses will enga e ears and sna them from the stalks.
with gears 8 wlth gears hbuld any of the stalks be presented crosswise to the rolls they will be directed into the longitudinal grooves 18 and be carried between the rolls without spreading them apart. It will be noted in Figure 2 that the grooves on the rolls of each pair are adapted to register during the rotation of the rolls.
that is claimed is 1. In a corn harvester, superposed pairs of snapping rolls each having longitudinal grooves extending from end to end and longitudinal series of pockets disposed in sta gered relation between the grooves, eac groove and each pocket having one wall disposed radially of the axis of rotation of the roll and having its other wall perpendicular to the radial wall. v
2. In a corn harvester, a snapping roll having longitudinal grooves extending from end to end thereof and longitudinal series of In testimony that I claim the foregoing as pockets extending from end to end between my own, I have hereto aflixed my signature 10 the grooves, the pockets of the series being in the presence of two witnesses.
staggered, the rear or following wall of each the axis of rotation and the other Wall of Vitnesses:
' groove and pocket being disposed radially of FRED B. DUES.
each groove and pocket being perpendicular J. J. DUES, to the radial wall thereof. JOHN G. Duns.
