871,824. Haymaking machines. VAN DER LELY N.V., C. Sept. 19, 1957 [Sept. 29, 1956], No. 29560/57. Class 6(3). A rake-wheel type side-delivery rake having rake-wheels which either operate all in unison or in groups, for swath-turning, comprises a first frame 5, 12 supported on three ground wheels 16, 27, 28, and carrying a first group of rake-wheels 1, 2, and a second frame 47 carrying a second group of rake-wheels 3, 4, the second frame being attachable to the first at various positions corresponding to the different haymaking operations. The first frame comprises a cranked beam 5 passing through the bearings 8, 9 rotatable about the cranked beam but normally fixed by latches 10, 11 the rake-wheels 1, 2 being obliquely and freely rotatably arranged on the bearings. The beam terminates forwardly in a member 12, to which a front swivel-wheel 16 and drawbar 18 are attached and rearwardly in a member 26 carrying lockable swivel-wheels 27, 28 at its ends, all the swivel-wheels being height-adjustable. Both members 12, 26 carry a plate 23, 41 to which the beam 47 carrying the rake-wheels 3, 4 can be alternatively attached by pins 45, 46 passing through aligned holes 25 in the plates 23, 41 and in a plate 44 carried by the beam 47. For side-delivery the rake-wheels are arranged as shown and the device is drawn in the direction V ; for swath-turning, the beam 47 is attached to the plate 23, so that the rake-wheel groups are parallel but the device is drawn in the direction V.1., whereas, for tedding, the device is drawn in the direction W, but the bearings 8, 9 are all rotated through 180 degrees so that the rake-wheels occupy the chaindotted positions. The rearmost rake-wheel 4 is detachable to reduce the weight on the beam 47 during transference. Specification 871,825 is referred to.
