732,304. Side-delivery rakes. VAN DER LELY N. V., C. June 4, 1953 [June 16, 1952], No. 15402/53. Class 6(3). A side-delivery rake, of the kind having a series of rake-wheels 1-6 obliquely-arranged to the line of travel is characterized in that supporting wheels 23, 29 for the frame are resiliently-mounted relatively to their supports 13, 14 and that rake-wheels are non-resiliently mounted upon these supports. The frame comprises an arched beam 30 terminating in the supports 13, 14 which are adjustable about vertical axes so that the frame may be swung into the dotted position (Fig. 1) for swath-turning. An adjustable arched arm 32 terminating in a swivel-wheel 33 is pivoted at 31 to the beam to provide lateral support for the beam and carries a hook 34 by which the rake can be towed. The supports carry horizontal axles 8, 11 for the rake-wheels 2, 5, and axles 19 for arms 15, 17 carrying the rake-wheels 1, 4, the rake-wheels 3, 6 being carried on further arms 16, 18 pivoted to the axles 8, 11. The swivel-wheel axle 21 is mounted in a tube 20 in which it is adjustable by a screw 28, the tube 20 being carried by parallel links 24, 25 pivoted to the support 13. A bracket 45, integral with the tube 20, is attached by springs 40, 43, 44 to the support 13 and to the arms 15, 16 respectively. The springs 43, 44 support the rake-wheels 1, 3 and oppose the spring 40, thereby assisting in supporting the frame 30. The device may be adapted for tractor or animal draught.
