United States My invention relates to new and useful improvements in swath turning assemblies, an object of my invention beingto provide a'device of the character herewithin described whereby the swath of grain lying in the field atent O may be picked up, and relaid rearwardly of the devicein a position toone side but parallel therewith the original swath.

A further object of my invention is to provide a device of the character herewithin described which, in conjunction with] the foregoing object, permits the swath to be replaced at the side of the original path and therefore upon ground which has been exposed to the air previously and which therefore may be considered to be drier than the ground upon which the swath was originallylaid.

Yet another object of my invention is to provide a device of the character herewithin described which, due

to the obtuse angle of travel thereof, gives a more efficient pick-up as the stalks of the grain in the swathare usually aligned with the direction of travel.

Still another object of my invention is to provide a device of the character herewithin described which, during the pick-up'and transferring of the swath, redistributes the grain therein, thereby leading to a more efiicient air circulation and enabling the swath to be air cured more rapidly and fefficiently;

Still anotherobject of my invention is to provide a device: of vthe. character herewithin described which is simple inf construction, economical in operation, and

otherwise well suited for the purpose for which it is designed.

With the foreging objects in view, and such other objects and advantages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, my invention consists essentially in the arrangement and construction of parts all as here inafter more particularly described, reference being had to the accompanying drawings in which:

. Figure 1 is a perspective view of my device.

Figure 2 is an enlarged perspective fragmentary View of one end of the main beam with parts broken away. Figure 3 is an enlarged fragmentary view showing the drive means for the drum and roller at one end thereof.

Figure 4 is an enlarged fragmentary end view showing the drive means at the opposite end to that of Figure 3. Figure 5 is an enlarged top plan'view of one end of my device with parts broken away.

Figure 6 is a perspective enlarged view of one of the rollers thereof.

Figure 7 is a reduced schematic view of my device behind a tractor showing the sideways movement of the swath being turned.

In the drawings like characters of reference indicate corresponding parts in the different figures.

Conventional swath turning devices normally attempt to pick up the swath from the field, pass it rearwardly of the machine, and then lay it down in a similar position upon the ground. These machines suffer from several disadvantages, some of the principal ones being that the "ice ground upon which the swath is laid originally, normally does not get an opportunity to dry, which means that the drying of the swath itself is retarded. Furthermore, the average swath, when laid down, has the stalks thereof in alignment vwhich makes it extremely difiicult for a swath turner to pick up alarge percentage of the swath. My device overcomes these disadvantages by the fact that the swath pick up drum is angulated with respect to the direction of travel and therefore transfers the swath onto a path parallel to that upon which it was originally laid and, furthermore, due to the angle at which the pick up drum attacks the swath, a greater percentage thereof is thus elevated.

Proceeding now to describe my invention in detail it will be seen upon reference to the accompanying drawings that l have provided a main channel beam or frame membet 1 extending transversely. The end2 of the beam is provided with a forked bearing post 3 within which a wheel post 4 may pivot, a wheel assembly 5 being mounted for rotation upon this post in the conventional manner.

At the opposite end 6 of the beam 1, a further ground wheel 7 is mounted for'rotationupon a stub axle 8 and it will be seen thatthis stub axle is mounted for rotation within a pair of bearings 9 and 10 which in turn are bolted or otherwise secured upon the beam 1. It will be seen that bearing 9 is offset with relation to the beaml and it will be appreciated that the distance of oiiset of this bearing controls the angle at which the axis of the wheel "7 makes with the axis of the beam.

A hitch assembly 11 comprising a pair of links 12 and 13 is pivotally secured adjacent to the end 6 of the beam by means of theeyes 14, The links 12 and 13 convergeupon the wheels 5 and 7, trails rearwardly as clearly illustrated in Figure 7 of the accompanying drawings.

A pair of support plates 19 and 20 are secured at their lower edges 19 and 20" to the beam upon the upper surface thereof and extend forwardly as illustrated in Figure 1. These support plates contain bearings and in these, bearings 21' I have mounted for rotation a swath pick-up drum collectively designated 21. This drum is conven-' tional in construction for example such as is shown in U. S. Patent No. 2,592,269, and includes an axle 22, cylindrical spacing drums 23, transverse ribs 24 securedto the drums 23, and a plurality of swath pick-up tines 25 which extend outwardly radially between adjacentpairs,

of drums 23.

Rearwardly ofthe pick-up drum 21, I have provided a pair of parallel rollers 26 and 27 also mounted for rotation within bearings 26 and 27 contained in the plates 19 and 20, each of these rollers taking the configuration best shown in Figure 6 of the accompanying drawings. It will be seen that these rollers include a shaft 215 having a core 29 of substantially square cross-sectional configuration, the sides 30 of the core being concave as clearly illustrated. This core is covered with a sheath 31 following the configuration of the core thus making a concave sided roller as shown.

Rearwardly of the rollers 26 and 27 and mounted for rotation between brackets, one of which is shown at 32, is a further roller 33 of square cross-sectional comiguration which completes the swath moving portion of my assembly.

Means to rotate the drum 21, the rollers 26 and 27, and the roller 33, are provided in the form of a telesc'opic drive shaft 34 which extends from the power takeoff (not illustrated) of the tractor 17. The drive shaft connects through a universaljoint 35 to a further drive shaft 36 mounted for rotation within a pair of bearings 37 which in turn are supported upon a bracket 3'8 secured by bolts 38' to the main beam 1. A belt pulley 3:9v

is secured to the end'of' the shaft 3'6 and'carries belted which transfers power from the shaft 36, via a pair of parallel pulleys 41' mounted within bracket 42, to a further. beltipulley 43 secured to the end of-rhe shaft 230i. the rearmost of the two rollers and 27.

Also secured to the end of the shaftZSis a chainwheel 44 which carries a chain 45 extending around a corresponding sprocket 46 secured to the endof shaft 22 of the swath pick-up drum 23.. The lower run 45' of the chain 45 engages with the underside ofa further sprocket wheel 47 which. is keyed to the end of the shaft 48 upon which is mounted the foremost roller 26hereinabovedescribed. A sprocket wheel 4-9, mounted within a slot (not illustrated) in plate 19, for movement towards and away from the chain 45 permits tension to be adjusted within chain 45 and ensures that the lower run 45" thereof engages the aforementioned sprocket 47.

Turning now to Figure 4 of thedrawings, it will be seen that, a sprocket wheel 50 is secured upon the opposite end of shaft 28 and that a sprocket chain 51 extends around this wheeland around a further sprocketwheel 52 which is secured to the shaft upon which the rearmost of the pick-up drum 21 rearwardly or in the direction of arrow 53, causes the tines 24- to engage the swath and nection I have provided a pair of tension springs 54 ex:

tending between a bracket 55 depending from the main,

beam 1 and a bracket 56 secured by an adjusting screw 56, to a cross-member 57 spanning the links 12 and 13 of the hitch assembly 11. These springs, therefore, maintain normally the pick-up drum 21 at its highest point above the ground and the distance is selectively varied by the provision of a ratchet lever assembly 58. This lever assembly is secured by a pivot bolt 59 to the beam 1 at its lower end thereof, the ratchet lever 58' of theassembly being selectively engageable within a quadrantSS! upstanding from the links 12 of the hitch lliso, that movement of the lever 58 in the direction of the. arrow 59 causes the pick-up drum 21 to be lowered towards the ground against tension within springs 54, v

' Reference should now be made to the schematic diagram in Figure 7 of the accompanying drawingsfrom which it will be seen that the tractor 17, progressing in the direction of the arrow 18, draws the devicetherebehind,

and at an obtuse angle to the direction of travel. Rotations elevate same rearwardly over the drums and onto the rollers 26 and 27. These rollers in turn are revolving in the same direction and shake and move the swath rearwardly to be thrown off finally by roller 33 in a position to one side of and parallel to the existing swath path.

Since various modifications. can be made in my invention as hereinabove described andmany app arently widely dilferent embodiments of same made within the spirit and scope of the claims without departing from such spirit and scope, it istintendecl that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
