Patent GB-1443641-A (GB)
Title: Rotary cutting assembly
IPC: A01D34/416
Filed: 1974-01-03
Abstract: 1443641 Mowers G C BALLAS 3 Jan 1974 [5 April 1973 8 Jan 1973] 00250/74 Heading A1F A rotary mower comprises an electric motor 103 transmitting, via a vertically disposed shaft 120, rotational drive to a spool like storage member 130 and a concentrically mounted housing 126, having in its side walls, bearing surfaces 131 and 132 which surfaces define therebetween peripheral apertures 107 through which the free ends of non metallic flexible lines 105 protrude. The other end of the lines 105 is wound around the spool 130 which is looked against rotation relative to the housing 126 and shaft 120 by locking nuts 121 and 122. The lines may be pulled from the spool 130 by virtue of the lower flange 125 being resilient, in order to restore an adequate working length of lines after the occurence of a breakage. A fixed blade 110A is provided for trimming the free ends of the lines after their length has been restored so as to ensure a correct working radius. When in use centrifugal forces extend the free ends of the lines 105 in a radial direction and maintain the lines in a yieldably rigid state. Under normal conditions the lines abut the leading edges 131 of the apertures 107 but when a relatively immovable object is struck by a line the line leaves this surface and falls 'back into a trailing edge 132 of aperture 107. These edges are arcuate having a relatively large radius of curvature so as to distribute the forces acting on the line under such conditions over as large a length of line as possible thereby minimizing the risk of breakage. The diameter of the lines lies in the range 0.035 inches to 0.1 inches and the tip velocity of the lines free end has a specific functional relation to the line diameter. In operation the lines cut vegetation in a flail like manner, yielding to more solid objects such as stones, trees, fences and feet providing a degree of safety.  In another embodiment Figs. 5 and 6 (not shown) the trailing edges (232) have a greater radius of curvature. In a further embodiment Figs. 7 and 8 (not shown) housing 126 is replaced by a pair of pins (318) and (319) the circumferential spaces therebetween constituting the apertures of the former embodiments, and a semi spherical or ellipsoidal shoe (307) is provided to enable the head to rest on the ground when in use

Title: A loom shuttle swell
IPC: D03D49/52
Filed: 1945-01-10
Abstract: 588,938. Loom shuttle swells and stopmotions. MACRO, S. Jan. 10, 1945, Nos. 810, 21766 and 25397. [Classes 142 (i) and 142 (iii)] The swell A, which may be loaded by an adjustable leaf or other spring, is carried by equal or unequal links B, B<1> which keep it parallel or substantially parallel with the plane in which it has been set. The pivots C are in advance of the pivots D, D' relative to the incoming shuttle so that the braking pressure is increased, as the shuttle arrives and relieved when it is picked. The angle of the links (and hence the induced braking effect), and the protrusion of the swell into the box, can be adjusted by a screw H and by moving the pivots D, D' along slots. A stop-motion acting if the shuttle fails to box may be operated by a lever K<1> pivoted at D' or elsewhere and resting on the swell at K<2> or against one of the links. Or the link B may be extended beyond its pivot D and the lever K<1> bolted to it, or the lever may be integral with the link. Or the lever may be pivoted to an extension of a link and also rest against the link or the swell so that the angular movement of the lever is greater than that' of the link. When the shuttle boxes, the lever K<1> displaces a finger J so that a tongue is lifted clear of a frog and the stop motion is not actuated. In a modification applied to a circular shuttle box, the protrusion of the swell into the box is limited by stops abutting the ends of the swell. In a modification applied to a two cell drop box the swells are loaded by torsion springs acting on the lever K' which carries a roller resting on the swell.
