Abstract

1325484 Rake-head for haymaking machines MASCHINEN FABRIK FAHR AG 20 Aug 1970 [30 Aug 1969] 40067/70 Heading A1F A rotary rake-head for haymaking machines comprises means by which the prongs are moved from their substantially horizontal transport position to their operating position by or as a consequence of centrifugal force. The rake-head comprises a hub 3 rotatably mounted on an axle 2 to which a guide member 10 is rigidly connected. Spokes 11 are provided with resilient prongs 19 secured to plates 18 which in turn are welded to sleeves 17 rotatably mounted on the spokes 11. The rotation of the spokes, and consequently also of the sleeves 17 and prongs 19, is achieved by an inclined disc 15 mounted on the axle 2 and provided with a cam-plate 16. The spokes 11 are guided in the cam-plate 16 by means of a shoulder 12 which acts as a crank 4 in which a bolt 13 provided with rollers 14 is inserted, so that the prongs 19, rigidly connected to the spokes, rise from the ground over a certain portion of their path. The sleeves 17 are connected to the guide member 10 by means of springs 24 joining the eyelets 25, 26. As the rake-head rotates, the sleeve 17 is brought to the operative position by centrifugal force, guided by mounting tracks 27, and secured by variously shaped locking devices, in this case by the bolt 21 engaging in the recess 22. When the power is switched off, the sleeve 17 is pulled inwards as far as the stop 23 by the spring 24, and the prongs assume their transport position by means of a counterweight 20 affixed to the sleeve 17. In a further embodiment the inward end of the sleeve is curved and moves over a similarly curved part of a shoulder of the guide member when the rake-head is not in motion thus bring- ing the prongs to their transport position. In another embodiment, Fig. 7, the spoke 72 is tubular, containing a bolt 76 mounted on a guide member 75 affixed to a spring 78, and the bolt 76 engages in a recess 79 in the sleeve 73 when the rake-head is in motion. A counterweight 80 brings the prongs into their transport position, as before.
