Title: Improvements in Agricultural Ploughs.
Inventor: CUNNINGHAM WILLIAM
IPC: A01B3/20
Filed: 1917-09-12
Abstract: 118,421. Cunningham, W. Sept. 12, 1917 Ploughs.-Relates to a one-way plough in which a chip h connecting the shares a has secured to it by a ball-and-socket joint a pin t, which projects through a slot b<1> in the beam of the plough and carries at its upper end the handles q and an extension q' thereof to which the horse is attached. The pin t also carries a shank t<2> projecting rearwardly and provided with hooks t<3>, t<4>, adapted to engage loops of chain or steel rope u, u<1> fixed to the hangers c supporting the plough. When the horso is turned at the headlands, the pin t is free to move towards the middle of the slot and the hook on the shank t<2> is released from its cable, thus permitting the turning of the handles and the pin t until the other hook engages the other cable. The beam may be provided with a pratt to hold the extension q<1> in any desired position horizontally relatively to the beam. The beam carries at each end an adjustable coulter d, land wheel e, and furrow wheel f. A roller may be arranged in front of and above the cutting edge of each coulter, to prevent accumulation of manure, weeds, &c. The chip h is arched on the under side to clear the bottom of the furrow, and is provided with a roller m to support the plough at its middle point. Rollers h<1> are mounted on the side of the chip to ease the passage of the shares through the soil. The breasts a<1> of the shares are connected together at their rear ends where they are provided with a pin a<2>, on which an extension a<3> may be hinged to lengthen the breasts when required. A presser wheel p mounted on an axle p<1> carried in a bearing secured to the under side of the beam may be provided. A steering rod p<3>, which can be adjusted in slots p<5> in an arm p<6>, is provided with a sleeve fitting over the axle p'.

Abstract: 1,167,494. Controlling clutches. ERNEST SCRAGG & SONS Ltd. 26 Jan., 1967 [27 Jan., 1966], No. 3632/66. Heading F2L. [Also in Division D1] In tape drive mechanism for textile spindles, in which one spindle is, or a group of spindles are, driven by a tape from a drive-pulley, support means are provided for at least one tapeengaging element comprising a flexible member capable of flexing so that the element can move between a first position in which it tensions the tape, and a second position in which the tape is slackened. The invention is described as applied to a spinning frame having two banks of spindles, each bank having its own drive shaft 17, and each spindle has its own tape 23 driven from the shaft by its own drive pulley 18. The support means comprise a flexible member 22 connected at one end 22b to a flange 16 of the spindle-rail 11, and at the other to a rigid plate member 20 to which the element i.e. an idle tensioning pulley 24 is attached. The axis of this pulley is parallel but spaced from that of the drive pulley. The support means is biased by a spring 29 to a position where it moves the tensioning pulley towards the wharve 13 and slackens the tape. It is held on tensioning pulley by a cam 31 attached to the plate 20 which co-operates with a roller 32 on a pedal rod 33, which can be moved to tighten or slacken the tape, catch means being provided to hold it. A second idler 25 is provided on the plate 20 with its axis at right angles to that of idler 24. In other forms, the tensioning of the tape is effected by an idler in the position of the idler 25, another idler being provided either in the position of the idler 24 or mounted adjacent the drive pulley 18.
