Application filed November 9, 1917. Serial No. 201,141.
1 0 all whom it may concern:
Be it known that I, SAMUEL M. Lu'rz, a citizen of the United States, residing at Kingman, in the county of Kingman, State of Kansas, have invented certain new and useful Improvements in Grain-Lifting Devices; 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.
"his invention relates to new and useful improvements in attachments for grain separators, and pertains more particularly to devices for handling headed grain.
The primary object of the invention is to provide a device by means of which headed grain may be manipulated to be fed to a grain separator. 1
A further object of the invention is to provide a device of this character which is power operated, the device deriving its power from the machine on which it is used.
Figure 1 is an end view of a separator having my improved structure mounted thereon,
Fig. 2 is a horizontal sectional view,
Fig. 3 is an enlarged detail view of one of the boom supports, v
Fig. 4: is another enlarged detail view of the same portion of the mechanism,
Fig. 5 is a transverse section on line 55 of Fig. 1, and
Fig. 6 is a detail of one of the crane constructions.
Referring more particularly to the drawings, 1 represents the. base of the mechanism which is mounted upon the platform of a grain separator in any desirable or suitable manner. Carried by the base 1, upon opposite sides of the machine, are the stanchions 2 which are provided with the enlarged heads 3 so as to provide com paratively widely extended top surfaces. The stanchions 2 cally recessed to provide step bearings for booms 4:. The booms are therefore rotatable in the stanchions 2 and at their upper ends are guyed by means of a transverse connecting rod 5, the angularly directed guy rods 6 and forward and rear guy rods 7. Each of the booms 4. carries a crane arm or spar 8, whose foot is heeled upon a bearing collar 9 which surrounds the corresponding boom. in fixed relation thereto above the top surfaces of the heads 3. The outer are centrally and vertiends ofthe spars or crane arms 8 are connected to the heads of the booms 4 by means of cables 10 which are passed in adjustable relation through the blocks 11 which are carried by the booms and spars so that the crane arms may be adjusted for height, or may be lowered on to the separator when the latter is packed for transport.
Furthermore, the collars 9 are annularly provided with worm gear teeth, which are adapted to alternately mesh with the worms 12 and 13 which are fixed upon shafts 14 and 15 respectively. Said shafts 14 and 15 are journaled in slide plates 16 which restupon the tops of the heads 3, and are yoked around the collars 9 in such a manner as to have a certain degree of slidability. The worms 12 and 13 are mounted upon the shafts la and 15 respectively between the bearings of the latter upon the plates 16, and therefore stand opposite the worm gears which are formed upon the collars 9, and owing to the slidable relation of the plates 16, may be alternately carried in the mesh with the worm gears. Thus, by means of the manipulation of the plates 16, the booms may be rotated in one direction or the other in accordance with the worm 12 or 13 which is brought into mesh with the worm gear. In order to slide the plates 16, the latter are connected by links 17 with hand levers 18 which are mounted upon the free ends of fixed arms 19 which project from the sides of the stanchions 2. V v I The shafts 14: and 15 are driven by means of a counter-shaft 20 which is mounted upon the base 1 below the shafts 14 and 15 and is provided with a belt pulley 21 which is adapted to be connected to the most conven ient part of the driving power of the threshing machine. The counter-shaft 20 is geared to the shaft 1i by means of a sprocket chain 22 which runs over sprockets 23 and 24; carried by the shafts 14c and 20, and the shaft 15 is also driven by' means of a sprocket wheel or chain 25 which connects the twoshafts 14 and 15. Mounted upon the shaft 14 is a pair of drums 26 which are loosely carried thereon, but may be fixed thereto by means of the clutch members 27 which are adapted to be operated by means of clutch levers 28. Cables 29 which are wound upon the drums 26 pass through pulleys 30 carried by a horizontal guy rod 31 and thence through pulleys 32 on the upper ends of the booms 4, to pulleys 33 on the outer ends of the spars 8, from which the cables then suspend to carry the forks 34.
In the operation of the mechanism above described, grain may be rapidly and continuously fed to the threshing machine feeding table from stacks on both sides of theseparator. Furthermore, the grain may be fed With a minimum of effort, since the lifting is entirely done by mechanical means, and workmen are only required to feed the forks 34c and to control the action of the fork lifting drums and the rotation of the cranes. The drums 26 are controlled in an obvious manner, while the rotation of the booms 4 is occasioned by carrying one .or another of the worms 12 or 13 into engagement with the worm gears by sliding the plates 16 across the head 3. Since both of the shafts l4 and 15 are continuously driven by means of flexible drive chains, the slight movement which is necessary to carry the gears 12 and 13 into engagement with the worm gear does not interfere with the continuous motion of the shafts, and the rotation of the booms l is effectively accomplished without the use of a complicated reversing gear.
What I claim as my invention is l. A device of the class described including a base, a plurality of booms upstanding from the base, spars carried by said booms,-
a turningcollar mounted on the lower portion of each boom, worm gear teeth on said collars, a pair of plates mounted on the base adjacent the booms and slidable transversely of the booms, bearings on said plates, a pair of shafts extending longitudinally between the booms and j ournaled in the bearings and having their ends disposed at the sides of the turning collars, gear worms 011 the ends of the shafts adapted to selectively mesh with the teeth of said collars, means for sliding the plates transversely of the booms to selectively engage the gear Worms with the collar teeth, and means for driving the shafts,-

3. A device of the class described includ ing a base, a plurality of booms upstanding from the base, spars carried by said booms, a turning collar mounted on the lower portion of each boom, worm gear teeth on said collars, a pair of platesmounted on the base adjacent the booms and slidable transversely of the booms, bearings on said plates, a pair ofshafts extending longitudinally betwee: the booms and journaled in the bearings and having their ends disposed at the sides of the turning collars, gear worms on the ends of the shafts adapted to selectively mesh with the teeth of said collars, means for sliding the plates transversely of the booms to selectively engage the gear worms with the collar teeth, means for driving the shafts, lifting drums loosely mounted 011 one of the shafts, means for clutching said drums to' the shaft and cables wound on said drums and connected with the spars.
