Abstract

1400269 Hay making machines MASCHINENFABRIK FAHR AG 26 Oct 1972 [23 Dec 1971] 49343/72 Heading A1F A hay making machine has a rake head 1 which rotates about a fixed hollow axle 3 and a cam disc 17 which is slidably mounted on the axle 3 and is moved axially therealong by a screw threaded spindle 18 between a position for swathing in which it is engaged by rollers 16 of control levers 14 connected to radially extending tined arms 11 and so causes the arms to oscillate about their longitudinal axes between raking and release positions as the head rotates and a position for tedding in which it is disengaged from the roller 16 so that the tines 12 extend downwardly. In the swathing position, the rollers 16 are biased against the cam disc 17 by respective torsion springs 13 which are contained in respective bearings 10 for the arms 11 and in the tedding position, these springs urge the other end 15 of the control levers 14 against stops 15 connected to a rim 9 of the rake head. The lower end of the threaded spindle 18 engages a nut 20 having lateral bolts 21 which pass through longitudinal slots 22 in the tubular wall of the axle 3 and are connected to a hub 24 which in a preferred construction is integral with the cam 17. A disc 25 is rigidly fixed to the axle 3 and the hub 24 carries an arm 27 with a ground roller 28. In a modification (not shown) the hub 24 and cam disc 17 are two separate parts and a compression spring, surrounding the axle 3, is placed between the disc 25 and the cam disc 17 to urge the disc 17 against the hub 24. The rake head 1 is connected to a sleeve 8 having a bevel gear 29 which engages a pinion on a drive shaft. The hay making machine may have one or a plurality of such rake heads and, in the case of a number of rake heads, adjacent pairs may be rotated in the same or opposite direction. Reference has been directed by the comptroller to Specifications 1238528 and 1174420.
