GRAIN-DRILL CLEANER.

Specification of Letters Patent.

Patented Apr. 16, 1918.

Application filed August 29, 1916. Serial No. 117,531.

T0 all whom t may concern: Y

Be it known that T, EDWARD L. VAN VLEET, a citizen of the United States, re-

siding at Goodland,y in the county of Sherman and State of Kansas, have invented certain new and useful Improvements in Grain- Drill Cleaners, of which the'following is a specication.

This invention relates to picker attachments for drills and the object of the same is to provide a. device as specified thatis simple in construction, efficient in operation and consists of the minimum number of parts.

1V ith these and other objects in view, this invention consists of certain novel constructions, combinations and arrangement of parts, as will be hereinafter fully described and claimed. f

Tn the accompanying drawings:

Figure 1 is a view in end elevation of my device in connection with a drill.

F ig. 2 is a top plan view of the same as shown in F ig. 1.

Fig. 3 is a fragmentary longitudinal sectional view taken through a portion of one of the shaft supporting brackets.

Referring to the parts by reference numerais, the frame of the drill is designated by the numeral 10, the axle by the numeral 11 and the supporting wheels by the numeral 12. The picker proper comprises a shaft 13 having secured thereon at uniformly spaced intervals the pickers 14. This shaft 13 is rotatably carried by the frame 10, the supporting arms 15 having the castings 16 at the lower end thereof through which the shaft 13 is passed. These castings are at uniformly spaced intervals on the shaft 13 between the pickers 14. A crown gear 17 is keyed to the shaft 13 adjacent one end thereof and a substantially U-shaped bracket 18 is also carried by this shaft 13 adjacent the ends of the same that has keyed thereto the crown gear 17. A plurality of collars 19 are keyed to the shaft 13 to retain the crown gear 17 and the bracket 18 in position as clearly shown in Fig. 2. On theaxle 11 is a crown gear 20 and also a substantially U-shaped bracket 21, the said gear and bracket being secured in the desired position on the axle by means of the keyed dollars 22. 1t is to be understood that the gears 17 and/20 are keyed to the shaft 13 and aXle 17 respectively, for rotation therewith. The substantially U-shaped brackets 21 has formed therein an elongated slot 23 and in alinement therewith is an opening formed in the bracket 18. A shaft,

Therefore by rotation of the axle 18, f the v shaft 13 is rotated therewith by means of the shaft 18 and the intermeshing gears 17 and 28 and 20. Y

T have provided a means whereby the shaft 11 can be rotated independently of the shaft 13, the same comprising a pedal 29 that is pivotally carried by the spaced ears 30 on the frame 10 and terminates in a forked end 31 that embraces the large portion 26 of the shaft 24C. As has been previously set forth, the enlarged portion 26 of the shaft 24 above mentioned is journaled through the slot 23 in the bracket 21 and is normally retained in such a position in said shaft as to retain the spur gear 28 that is secured thereto in mesh with the lcrown gear 20. This retaining means comprises a strip 32 that passes through a slot 33 formed in the bracket 21 and projections 34 are formed on this bracket 21 to receive one end of the bolts 35 each of which has the opposite end thereof passed through the strip 32. Coil springs 36 are wound about these bolts 35, the said springs being of the eXpansible type and normally move the shaft 24. so as to retain the spur gear 28 keyed thereon in mesh with the crown gear 20.

Tt is obvious that when it is desired to have the axle 11 rotate independently of the picker all that is necessary is to apply pressure on thev pedal 29 and thus move the shaft 24C so as to move thel spur gear out of mesh with the crown gear 20. It is to be understood that the opening in the bracket 18 through which the .reduced portion 25 of the shaft 24 is journaled is of such "size as to permit slighty movement of the shaft for this desired function.

lt is to be noted that the pin 32 in the slot 33 is limited in its movement by the slot so that the pin will not force the shaft against one end Wall of the slot 23 and thus bind the shaft and prevent the ready rotation thereof.

t'is obvious that minor changes may be made in the form and construetioniof this invention Without departing from the 1na terial parts thereof. it is therefore not WisheL to confinethe invention to the exact form herein'shovvn and described, but it is wished to'inclnde all such as properly come Within the scope claimed.

l. In combination with a drill having a frame, supporting Wheels therefor' and an axle having a gear keyed thereto and a bracket thereon, of a rotatable Apicker cornprising a shaft and series ofpickingelements, a substantially U-shapedbracket on said shaft, a gear Wheel keyed to said shaft, a second shaft journaled through said bracket and having a gear Wheel thereon in mesh with said gear Wheel on said picker, a second gear on said second mentioned shaft and in engagement With said gearon said axle whereby by the rotation of said axle rotary movement Willxbe imparted to said picker, means on said bracket on said axle and :in engagement with said second shaft lto vnormally retain certain of said gears in :mesh andmeans for moving said Vsecond mentioned shaft to move vsaid last mentioned gears out of mesh.

2. In combination with a drill including an axle, of arrotatable picker, means to rotatesaid picker including a shaft having pin for ynormally urging the saine into engagement Withsaid shaft toretain said gear Wheel in .mesh and means for moving said shaft in said openinmin said'support against the tension of said springs to move said gears out of mesh.

3. in combination with a drill having a gear keyed to'themain axle thereof, of a :rotatable picker, a shaft for imparting rotary movement to said picker having a gear thereon, a bracket carried by said main axle and means on said bracket for normally retaining said gears in mesh and a second means for moving said gears out of mesh as and for thepurpose set forth.

.Intestimony whereof l afdx my signature in presence of two Witnesses.
