GRAN-CLEANER ATTACHMENT THRASHING MACHINES.

Application filed April 21,

To all w hom t may concern,

Be it known that I, Moses J. DoRAN, a citizen of the United States of America, residing at Pierpont, in the county of Aishtabula and State of Ohio, have invented certain new and useful Improvements in Grain-Cleaner Attachments for Thrashing Machines, of which the following is a speciication. I

The primary object of the present invention is to provide a grain-separating spout adapted for oscillatory suspension within a thrashing machine spout for the reception of the thrashed grain as it leaves the machine and whereby clean grain may be bagged at the thrashing machine which will not require further cleaning or separating.

A further object of the invention is the provision of an auxiliary spout for receiving the grain from a thrashing machine for separating and conducting clean grain to one side of the machine and the waste to the other side thereof, my device being adapted for agitation by connection with a movable part of vthe machinery of the thrashingmachine with which the deviceis employed.

A still further object of the invent-ion is to provide a separating spout that is simple in construction, easy and inexpensive to manufacture and may be easily installed upon an ordinary thrashing machine for the final separation and `cleaning of the grain from the chaff.

With these objects in view theinvention consists of the combination and arrangement of parts hereinafter more fully de'- scribed in connection with the accompanying drawing andin which like reference characters designate corresponding parts throughout the several views.

In the drawing,

Figure 1 is a side elevational view of the invention illustrating in dotted lines a manner of suspending and oscillating the same,

Figure 2 is a central longitudinal sectional view thereof,

Figure 3 is a top plan view of the same,

Figure l is a transverse sectional view taken upon line IV-IV of 'Figure 1, and

Figure 5 is a similar sectional view taken upon line V-V of Figure 1.-

Referring more in detail to the drawing, it will be understood that my invention is an attachment for use within the grain spout of a thrashing machine and broadly 1921. Serial No. 463,259.

consists of an auxiliary spout having opposite sides 10 and 11 with an inclined bottom 12, and a sieve vor screen 13 oppositely inclined above the bottom 12, for receiving grain directly thereon. rlhe sides 10 and 11 are adj ustably connected together by four transverse bolts 14k having heads 15 outwardly of the side 11 with winged nuts 16 threaded upon the opposite ends of the ybolts outwardly of the side 10.

The screen 13 is pivoted adjacent its higher end 17 upon one of the upper bolts 14: and extends between the sides 10 and 11 beneath the corresponding upper bolt at the opposite end of the spout while the bottom board 12 rests with its lower end 18 upon the bolt let beneath the end 17 of the screen and with the upper end of the bottom 12 between the sides 10 and 11 at a considerable distance inwardly of the lower end of the screen 13. The bottoniv 12 and screen 13 are maintained adjustably inclined in opposite directions by tightening the nuts 16 upon the bolts 1li, thereby securing the same between the sides 10 and 11.

vThe screen being adapted for the reception of grain, the device is designed for suspension for ready oscillation within the discharge spout of thrashing machine and suspending members such as hooks 19 illustrated by dotted lines may be employed for this purpose engaging beneath the upper corner extensions 2O of the sides 10 and 11. The draft from, the thrashing machine serves to blow away the 'chaff and vwaste which with the grain travel upon thescreen 13 toward the lower end 21 thereof when 4the device is longitudinally oscillated as by -means of a pitman 22 herein illustrated by dotted lines adapted for connection with any suitable moving part of the operating mechanism of the thrashing machine.

i grain saver is provided adjacent the lower end of the screen 13, consisting of a metallic shelf 23 beneath the foraminous member 24E of the screen 13 and oppositely inclined whereby grain passing through the foraminous member 24 beyond the sides 10 and 11 falls upon the shelf 23 and by reason of the oscillations of the device the grain passes to the inclined bottom 12 and is discharged at the lower end 1S thereof for bagging. Suitable cross braces 25 are provided for the screen `13 and it will be evident that the relative inclination of the screen 13 and bottom 12 may be changed as found de sii-able as indicated by dotted lines in Figure 2, of the drawing. The shelf 23 has an end wall 26 engaging the foraminous member 24; at the lower end 21 of the screen 13 so that the shelf 23 collects and saves all of the grain that would be otherwise lost by falling outwardly of this end of the auxiliary spout. The lower end of the shelf 23 is adapted to overlie the upper end of the inclined bottom 12 thereby constituting in reality a continuation of the bottom 12. It will thus be seen that the grain passing' from the shell 23 will fall onto the inclined bottom 12 to be discharged at the lower end 18. By so providing the screen 13 with the shelf 23 the cost of production of the entire device will be greatly decreased. It will alleviate the necessity of providing a bottom 12 and side walls 10 and 11 of the same length as the screen 13 and at the same time will provide a relatively long screening surface Q4 for the screen 13.

The complete operation of the invention will be fully understood from this detailed description thereof, and while the form of the invention herein set forth is believed preferable, it will be understood that changes may be made therein without departing from the spirit and scope of my invention.

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is

1. An auxiliary grain spout comprising side walls, an inclined screen pivoted at its upper end between said walls and extending beyond said walls at the opposite end of the device, an inclined bottom positioned between said side walls and a shelf beneath the lower end of the screen adapted for dis charge upon said bottom.

2. An auxiliary grain spout comprising side walls having upper end extensions, upper and lower bolts adjustably connected between said walls, a screen member pivoted upon one of said upper bolts and beneath the other upper bolt extending longitudinally between said walls, an inclined bottom board beneath the screen with its lower end positioned upon one of said bolts beneath said upper pivoting bolt and an inclined shelf beneath the lower end of the screen overlying the upper end of said bottom board.

A grain spout adapted for oscillatory movement comprising sides, a screen of greater length than said sides positioned therebetween, a bolt connected through said sides pivotally engaging the upper end of the screen, an adjusting bolt secured between said sides adjacent the opposite end of the device positioned above said screen, an adjustable bottom board oppositely inclined beneath the screen and a shelf beneath the screen having a discharge end above said board.

4t. A grain spout adapted for oscillatory movement comprising sides', a screen of greater length than said sides positioned therebetween, a bolt connected through said sides pivotally engaging the upper end of the screen, an adjusting bolt secured between said sides adjacent the opposite end of i the device positioned above said screen, a

shelf beneath the lower end of the screen having a closed end portion engaging the screen, the shelf being inclined downwardly toward the pivotal end of the screen and a bottom board beneath the screen and shelf adjustably positioned between said sides.

5. A grain spout adapted for oscillatory movement comprising sides, a screen of greater length than said sides positioned therebetween, a bolt connected through said sides pivotally engaging the upper end of the screen, an adjusting bolt secured between said sides adjacent the opposite end of the device positioned above said screen, a shelf beneath the lower end of the screen having a closed end portion engaging the screen, theshelf being inclined downwardly toward the pivotal end of the screen, a bottom board beneath the screen and shelf adjustably positioned between said sides, a lower bolt between said sides beneath the pivoting bolt, a bottom board oppositely inclined with respect to the screen positioned beneath the screen with its lower end upon said bottom bolt and adjustable retaining means between the sides beneath the opposite end of said board.

In testimony whereof I atix my signature.

MOSES J. DORAN.
