1,024,726. Hay balers. GEBR WELGER. Aug. 27, 1963 [Aug. 30, 1962; July 12, 1963 (2)], No. 33884/63. Heading B5F. [Also in Division A2] Bales of e.g. hay, which cohere without binding or tying, are produced by rolling the hay in a conical chamber W formed by circularly disposed rollers 2-6, of truncated cone shape as in Figs. 1 and 2, all of which are rotated in the same direction by a main shaft 9 acting through a gear 10 and co-operating gears 8. Material is fed from deck 1 into the chamber by retractable tines 7 mounted upon roller 2 and is rolled into a continuous cylindrical bale which is forced from the chamber into an axially aligned cylinder 11, rotated, in the same direction and speed as the continuous bale, by a pulley and belt 15, 14. The density of the issuing bale is controlled by adjustable leaf spring 20 which project into the interior of the cylinder. Spring biased members 23 are mounted upon a sleeve 24, which is reciprocated along the cylinder, by the pin 26, of lever 27, which co-operates with groove 25 of the sleeve, so that when the members are forwarded with the bale but at a greater speed the members bite into the continuous bale and tear off an individual bale which is then removed from the machine. In an alternative embodiment in Fig. 3 (not shown), the chamber comprises four rollers, one of which, 30, is driven directly by shaft 34, the others being driven through a gear 36 mounted upon a cylinder 37 having bale density controlling springs 39. The bale issuing from the cylinder passes through stationary cylinder 45 and abuts flaps 47, adjusted to yield under a certain pressure against the action of spring 50. When the flaps yield a one-revolution clutch is actuated by link mechanism 48, 55, 56 which rotates tearing member 51 to tear off an individual bale. The above baling mechanism may be mounted upon a side feed baler as in Figs. 6 and 7 (not shown), individual bales being ejected by resilient rotating rollers.
