HULLING ATTACHMENT FOR THRASHING MACHINES.
Application filed August 1, 1922. sci-m1 No. 572,940.
useful Improvements in Hulling Attachments for Thrashing Machines; and I do 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.
This invention relates to an improved hulling attachment for use in connection with thrashing machines and one object of the invention is to provide a hulling attachment which may be placed beneath the upper discharge end of a return pipe of the thrashing machine so that feed such as clover and alfalfa feed which have passed through the thrashing machine without be ing properly threshed may be hulled and returned to the thrashing machine before being again passed through the thrashing machine.
Another object of the invention is to provide this hulling attachment with an improved type of concave and an improved type of roller or cylinder, the cylinder or roller having an improved operating face and the concave being formed in sections yieldably held in an operative position with respect to the roller and movable away from the roller.
Another object of the invention is to so construct this attachment that it may be easily assembled and to further so construct it, that the sections of the concave can be very readily adjusted.
This invention is illustrated in the accompanying drawings, wherein:
Figure 1 is a view in side elevation showing the attachment in place in connection with a portion of a thrashing machine and positioned beneath the upper discharge end. of the return pipe.
Figure 2 is a top plan view of the attache ment with the upper wall removed.
Figure '3 is a vertical sectional view through the device.
Figure 4 is a vertical sectional view taken along the line H of Fig. 3.
Figure 5 is a horizontal sectional view taken along the line 55 of Fig. 3.
This hulling attachment is provided with a housing having side walls 1, front and rear walls 2 and 3, a top 4 and a bottom 5.
The side walls 1 are provided with side flanges 6 to receive fastener bolts which pass through the front and rear walls and with upper and lower flanges 7 and 8 to receive fastener bolts which pass through the top and bottom. Similar flanges 9 and 10 are provided at the upper and lower ends of the front walls to receive fastener bolts which pass through the top and bottom and it will be readily seen that by removing these bolts the housing can be readily taken apart and assembled. It will of course be obvious that the walls and top and bottom may be formed either of stamped sheet metal or maybe formed as casting. Side bars 11 are carried by the side walls 1 and carry bearings so that the protruding end portions of the shaft 12 of the roller 13 may be rotatably mounted. A pulley 14: is carried by one end portion of the shaft 12 so that a belt 15 operated from a pulley 16 of the thrashing machine may be passed about the pulley 14 and rotary motion thus transmitted to the roller 13. This roller 13 has its operating face provided with ribs 17 which are formed as shown in Figs. 2 and'3. From an inspection of these figures, it will be seen that these ribs 17 are V-shaped and extend from the center of the roller toward the ends thereof and further that when viewed in cross section, the ribs will cause the roller to have the appearance of being provided with saw teeth. The provision of the ribs extending from the center towards the sides of the roller in diverging relation will cause the clever and alfalfa feed which is to be hulled, to be spread upon the concave and hulled in a very efficient manner. The concave is formed from a plurality of bars 18 which are positioned side by side and at their upper ends are provided with eyes 19 through which will pass a securing pin or red 20. Therefore, the bars which form the concave will be pivotally mounted so that they may be moved towards and away from the roller. These bars have their lower end portions curved as shown clearly in Fig. and provided with transversely extending ribs 21 and have their lower free end portions extended downwardly and provided with lugs 22 about which will lit the springs 23. These springs 23 engage the abutment bar 24 about the pins 25 carried thereby and it will be readily seen that these springs will serve to yieldably hold the concave forming bars in engagement with the roller drop; ofi off the lower end of the concave but will permit of these barsbeing moved away flOIll. the roller. A cross bar 26 is mounted in the lower portion of the housing between the side Walls and carries set screws 27 to engage the depending end portions-of the bars 18--and move these bars away from the roller. These bars can therefore be set the propel distanceto permit of hulling of the feed without danger of crackingpthe feed.
WVh en this-:device-is in use and assembled as shown; it is put in place and mounted upon the thrashing machine indicated in general byrthe numeral 28 beneath the upper discharge end of the return conveyor- 29 ofthe thrashingunach-ine; The feed which is to; be returned passes upwardly through this; conveyor spout29'and will drop downwardly; into: the hopper'30 carried by the topA: ofthe housing and'positioned about anin'let'opening; Depending platesril are provided: along: the edges; of the inlet" ope-ning -oftthis housingsothat the'feedwill beguidedr asgit passes into'the housing-and directed into-- thespace between the concave and the-roller. This feed which is to be hulled is carried; along: the concave by the roller andbrought over the concave as: it ismoved longitudinally ot-the same. The feed will; be hulled and i the: hulled feed will down-unto thebottom of the housing and outthroughthe outlet ,at' opposite sides of which are provided depending guide plates- 32 These -guide-plates will cause the hulledfeed to be guided into an inlet of the thresher so that the feed will be again passed through the thrashing machine.
I, claim:
1. A hulling device comprising a housing having an inlet and an outlet, a cylinder rotatably mounted in the housing and extending between the inlet and outlet, a concave in the housing between the inlet and outlet and formed of longitudinally extend ing sections pivotally mounted at. their upper ends-and having their lower end portions'curved to conform to the contour of the cylinderand terminating in depending end portions positioned above the outlet, resilient meansengaging the depending end portions of the concave sections to yieldably hold the same against movement away from the cylinder, and means for engaging the depending end portions of the concave sections for moving the same against the action of the resilient'means.
2. The structure of claim 1 including cross bars in the housing beneath the-cylinder and upon opposite sides of the dependingv end of the concave, springs between the depending end portions of the concave sections and one of the cross bars, and setscrews passingthrough the other cross bar and engaging the depending ends of the concave sections.
Iii-testimony whereof I have hereunto set my hand.
WILLIAM R. HUGHES.
