352,162. Distributers for seeds. McCALL, T., 485, Govan Road, Glasgow. May 16, 1930, No. 15045. [Class 6 (i).] In a sowing-machine in which seeds are delivered from a receptacle to an overshot rotary feed wheel, the feed wheel comprises a pair of side discs or cheek plates and an intermediate plate or disc having pockets or recesses in its periphery, the several parts being made separate from one another and detachably secured together, so that the wheel may be adjusted for different kinds of seeds &c. by substituting a different intermediate recessed plate or disc. This intermediate disc may be of laminated form consisting of thin notched discs adjustable relative to one another so as to bring the notches or recesses into or out of register. The sloping receptacle 10 of the hand implement shown in Fig. 2 may be rectangular, with a tapered part 10a terminating in a feed spout having its outlet partially closed by a fixed or adjustable shutter. The feed wheel 12 extends into the feed spout and fits against a depending curved plate. The lower part of the feed wheel 12 may be enclosed in a casing which may be extended forwards and shaped to receive and distribute the seeds. The feed wheel is driven by one of two wheels 16, 18 running along a straight edge 17. It is removably secured on a spindle 13 and comprises two side plates or discs 19, 20 and one or more intermediate notched discs 24, the discs 20, 24 being adjustably secured on a hub on the disc 19 by a nut 22. By adjustment of the discs the notches or recesses 26 may be arranged to give a continuous or intermittent feed. In the arrangement shown in Fig. 6 the side disc 28 is connected to the side disc 27 by studs 37 and relative rotation of the intermediate disc 29 is prevented by a key 36. The discs 27, 28 extend beyond the disc 29 and are bevelled so that the feed wheel has a peripheral groove, into which the tapered feed spout 31 may extend. Several discs, or a disc having pockets of different size and spacing, may be substituted for the disc 29. The supply of seeds from the receptacle 32 to the spout 31 is regulated by means of a slide 39. A curved guard 41 fits against the disc 29.
