Title: Harvesting machines
IPC: A01D41/12
Filed: 1973-06-27
Abstract: 1460715 Harvesting machine CLAYSON NV 14 June 1974 [27 June 1973] 30634/73 Heading A1F A crop entering a harvesting machine is partially separated into grain and straw in a transversely extending threshing cylinder 6 before it passes into a rotary separating mechanism 27, of greater transverse extent than the threshing cylinder 6, where the crop is conveyed on a helical path 91 (Fig. 2) towards the end of the separating mechanism while undergoing a separating action. As shown, the crop is received into the threshing cylinder 6 from a conveyor 2, where it is struck and separated by rasp bars 10 as it is moved rearwardly. The crop passes to a straw beater 19 which is of the same transverse extent as the threshing cylinder 6 and in which the crop is further separated by beater plates 23 as it moves toward an opening in a casing 28 of the separating mechanism 27. Since the separating mechanism 27 is wider than the straw beater 19 the crop is fed to a central portion 37 of a first rotor 29 of the separating mechanism where it is engaged by tines 38, inclined rearwardly to the direction of rotation 86, and moved thereby to the central portion of a second rotor 30 where the crop is separated and split into two equal portions by separator vanes 50 which guide the crop onto a helical path 91 (Fig. 2). The crop moves almost one revolution on the second rotor 30 before it is reentrained by the first rotor 29, but, due to the helical action, at the ends which extend beyond the threshing cylinder 6, where it is again separated by separator vanes 43 and continues to be moved on a helical path until the crop reaches tines 40. Finally the crop passes back into the second rotor 30 where discharge vanes 51 impart a final separating action before discharging the straw through openings 57 (58). In each of the separating stages any grain separated falls through concaves, located under the threshing cylinder, straw beater and separating mechanism, to be collected. The rotor 30 can be positioned above the first rotor 29 (Fig. 9 not shown). In both rotor positions, the straw beater 19 may be omitted. In a further embodiment, the central area 37 of the first rotor 29 is replaced by a threshing mechanism. In a further embodiment, an intermediate wall, between the two rotors of the separating mechanism, defines two side openings through which the crop can pass from the first rotor to the second rotor (Fig. 12, not shown). In all of the embodiments described cutter means can be provided in the first rotor 29 to separate a single mat of crop from the threshing cylinder 6 into two equal portions.

Abstract: 695,701. Gearing for conveying rotary motion. COCHRANE, A. P. M. Nov. 2, 1949 [Dec. 2, 1948], No. 31280/48. Class 80 (i). To introduce a variation in the transmission ratio as between the central and either extreme position of a screw and nut gearing for e.g. a motor vehicle steering mechanism, an axially moving nut N driven by the rotation of a screw S on the vehicle steering column has a partial rotation imparted to it and furthermore carries a gear worm 10, of opposite hand to the screw thread, to engage the threads 11 of a worm wheel or section Q secured to the driven shaft 12, e.g. a pitman shaft. The nut rotation may be imparted by the engagement of a stud 2 located in the mechanism housing H with a slot in the nut, and the slot may be parallel with screw axis at its central portion and inclined to the axis towards its extremities to produce, depending upon the direction of inclination, an acceleration or alternatively a deceleration not only of the nut's axial movement, but also of the gearing 10, 11. In modifications, the relative positions of the stud 2 and slot 1 may be reversed, or the slot may be of partly circular section and engaged by a steel ball, or the slot may be replaced by a rib or projection for engagement with pins, rollers or balls. To prolong the life of the gearing the stud 2 is eccentrically supported in a housing cup piece 4 whereby partial rotation thereof causes different working surfaces of the slot and gear teeth to be used; also the sector Q is replaced by a complete wheel. The motion between the screw S and nut N may be transmitted by plain screw thread gearing, or alternatively by balls contained in a helix or helices as described in Specification 616,979. Specification 605,205 also is referred to.

[Class 40 (iv).] A magnet system particularly for loudspeakers, but also applicable to pick-ups and the like, comprises an armature adapted to oscillate about an axis which is substantially normal to the four ends of a pair of polepieces, and is characterized in that the armature can pass alternately between one and the other pair of pole-shoes, the driving member associated with the diaphragm or the equivalent engaging the armature between the pivotal axis and one end' of the armature. In the loud-speaker movement shown, two U-shaped flat pole-shoes d are secured to the ends of a horse-shoe magnet so as to face each other and provide two aligned air gaps in which an armature a is mounted. The armature is so arranged that it is virtually pivoted about an axis transverse to the air gaps, and it is adapted to vibrate with its ends moving parallel to the pole faces. The armature is connected by a rod c to the diaphragm (not shown), the point of attachment of the driving rod to the armature being located as described above. A U-shaped flat spring i supports the armature by being connected to a transverse part a<1> of the latter, the blades i<1> of the spring being screwed at g to a lug f which projects up from a strip e. This strip, of non-magnetic material, is secured to the underside of the polepieces d, bridging the gap between them. With this arrangement, the virtual axis of pivotation lies between the lug f and the member a<1>. The spring i may either be separately formed and secured to the armature, or may be integral therewith, transverse grooves being formed in the branches of the spring to define the pivotal axis. The armature may taper towards its ends in length and/or thickness. It may also be curved lengthwise, so that its immersion in the magnetic field is not constant. Fig. 10 shows a modification in which the armature is adjustably mounted on the support e. The armature a is in this case screwed to a member q, which is mounted by a leaf spring o in a recess in the part e. An extension r of the member q is adjustably controlled by a screw s coacting with a spring t.
