895,937. Side-delivery rakes. VAN DER LELY N.V., C. July 22, 1958, No. 23584/58. Class 6(3). A tractor-mounted side-delivery rake of the oblique rake-wheel type is capable of movement to several working positions corresponding to side-delivery, tedding and swath-turning, and in the sidedelivery position the rake-wheels work a swath which is laterally displaced from the track of the tractor 9 so that the latter does not run over the crop to be turned. The implement comprises a frame having a part 1 which is mounted on the tractor draught-links 6, 7, 8, and a part 2 which is movably mounted on the part 1 and carries the rake-wheels 19-22. The part 1 consists of U-shaped tubes 10, 11 terminating in two vertically-spaced coaxial bearings 13, 14. The part 2 consists of two parallel beams 15, 16 pivotally inter-connected by tubes 23, 24 to form a deformable parallelogram having apices 25 28, the' beams 15, 16 having extensions 17, 18, outside the parallelogram, which carry the rake-wheels on spring- loaded cranks 46. The parallelogram is secured against deformation by an arcuate strip 29, carried by the beam 15, to which strip the beam 23 is pinned at 33. For swath-turning, the pin 33 is removed and the parallelogram swung into the dotted position so that the rake-wheels form two groups of two 19, 20 and 21, 22, laterally spaced. The beam 15 is integral with two U-shaped beams 34, 35 which terminate in bearings 37, 38 coaxial with the bearings 13, 14 on the frame-part 1 so that the frame-part 2 can be swung bodily around the part 1 into the position shown in Fig. 4, without deformation of the parallelogram, the frame parts 1 and 2 being locked together in both positions by a stay 44 engageable with apertured strips 40, 67 and with lugs 42, 65, on the frame-part 1. In the position shown in Fig. 4, each rake-wheel operates independently so that the device is a tedder. Specifications 895,938, 895,939 and 895,940 are referred to.
