826,350. Side-delivery rakes. VAN DER LELY N. V., C. Nov. 25, 1955 [Nov. 27, 1954], No. 33864/55. Class 6(3). A side-delivery rake, of the type having an oblique series of rake-wheels driven by groundcontact, is mounted on tractor hitch-links so that the rake-wheels may either co-operate, for side-delivery, or operate separately for tedding and swath-turning. As shown in Fig. 1, the frame comprises a tube 9 carrying rakewheel axles 13, 14, 15 and a tube 16, at a higher level, the tubes being joined to a bar 21 which is attached to a triangular frame 28, 29, pivoted to the hitch-links 4, 5, 6, so that the implement frame can be adjusted, within limits, to the line of draught. Alternative hitchlink connections 48, 49, 50 are provided on the members 9 and 16 and the implement is in. verted when these are used, Fig. 3, the rakewheels then operating independently. Shoes 46 are carried by extensions of the rake-wheel stub-axles 13, 15 and support the implementframe, with the assistance of a chain 31 connected to the upper hitch-link connection 30. In Fig. 4, alternative hitch-link connections 61, 62, 63 and 89, 90, 91 are provided on the main frame 70 and the frame carries two additional stub axles 83 to which the two rearmost rake-wheels 84 may be transferred, to convert the device into a swath-turner having two groups of rake-wheels, Fig. 6 (not shown). The stub axles 82, 83 are swivellable about vertical pivots 78 and are carried by bushings 74 which are adjustable along the tubular frame 70. In Fig. 8, only one frame 106, 107 is provided for attachment to the hitch-links, the main frame being swivelly mounted in a tube 112 so as to be rotatable therein through 180 degrees in converting between the side-delivery and tedding positions. As shown, for sidedelivery the tube 118 carries stub-axles 125 for rake-wheels 126, two axles being extended to carry ground-engaging shoes 127. An axle 116 fixed to the tube 118 is floatable, within limits, in the tube 112 which can be pinned to a sector-shaped frame 108, on the hitch-links, at various angles to the line of travel. The frame 108 is maintained horizontal by a chain 114 connected to the upper hitch-link connection 103. The chain may, however, be replaced by a rigid link and the whole implement is then supported by one or more springs connected between the frame 108 and the tractor. Specifications 826,351, 826,352, 826,353, 826,354, 826,355, 826,356, 826,357, 826,358 and 826,359 are referred to. Reference has been directed by the Comptroller to Specification 793,434.
