Title: Improvements in or relating to motor turnwrest ploughs
IPC: A01B3/421
Filed: 1920-09-09
Abstract: 151,603. Dubois, L. L. Sept. 27, 1919, [Convention date]. Ploughs.-A motor turn-wrest plough is provided with means whereby the plough frame is caused to swing over when the machine is turned at the headlands. The plough frame 3, which is in two parts coupled by adjusting plates 4, 4' for the purpose of setting the shares correctly for any depth of ploughing, is rotatably supported in a vertically adjustable socket 15 on the tractor portion of the plough. The plough frame is locked in position by a spring-pressed pawl 11 which engages one or other of two notches on the plates 4, 4<1> and which may be lifted by the attendant. The tractor frame is carried by two main driving-wheels independently controlled and adapted to be engaged by brakes for the purpose of steering. The tractor frame also carries a front steering-wheel 5 which, when the ploughs are in working position, is raised from the ground. On arriving at a headland, the attendant reverses the machine. The reaction of the drive forces the front of the tractor downwards until the wheel 5 reaches the ground, the ploughs being lifted from the ground. The attendant then lifts the pawl 11 and holds one of the wheels of the brake. As the tractor pivots about the braked driving-wheel the ploughs rub over the ground and turn on their pivot in the socket 15. After the machine has turned through about 120 degrees, the motor is stopped and restarted in the forward direction, the brake being freed from the one wheel and applied to the other. The tractor frame swings on the wheels lifting the wheel 5 and depressing the plough frame so that the shares engage the ground and turn until the pawl 11 slips into its notch, after which the attendant releases the brake. Specification 145.077, [Class 79 (ii), Motor-vehicles, Driving &c.], is referred to. The Specification as open to inspection under Sect. 91 (3) (a) describes a modification in which it is stated that the turning of the ploughs may be produced by distributing the masses on the plough frame unevenly. This subject-matter does not appear in the Specification as accepted.

[Also in Division E2] A motor van has a fixed or removable body having a flexible closure member 10 with a leading edge 22 moving across an opening and being connected to chains or cables 14 which pass over sprockets 15, 16, 17, the sprockets 15 being driven by an electric motor 20. The closure member 10 is of corrugated resinbonded glass fibre or is of an articulated slatconstruction, and runs in guides 11. The motor, which is reversible, is stopped by the opening of switches MS1 or MS3 by cam 23 on fixed to the closure member 10; one or more microswitches attached to edge 22 can either stop or reverse motor 20 when the edge meets an obstruction, these micro-switches being rendered ineffective by a switch MS2 as the opening is closed. A push-button is used to start closing movement of member 10 which is opened by a switch needing a key for operation which may be the same key as controls the van engine. A remotely-controlled lock holds the member 10 in the closed position. Specification 827,218 is referred to.

Abstract: 1353356 Control apparatus-open-end spinning TOYODA JIDOH SHOKKI SEISAKUSHO KK and MEIDENSHA KK 19 April 1971 [8 April 1970] 26512/71 Headings DID and D1F The detection of yarn breakage at any spinning unit 10 (a-n), Fig. 1, of an open-end spinning machine causes a circuit 4 (a-n) of the unit to disconnect the unit from a central normal-running control 1 and to connect the unit either to a central control 2 for control during yarn repair or to a central control 3 to stop the unit to await yarn repair. When a detector 17 (a-n) of a unit detects a yarn breakage it emits a signal B which isolates the unit from control signal A of control 1, and which causes the associated circuit 4 to activate control 2 to emit signal G to control the unit. When the breakage is repaired, a signal H from control, 2 causes the circuit 4 to reconnect the unit to control 1. If a second breakage on a second unit 10 has in the meantime caused a second signal B to be emitted, this second signal will activate control means 3 to emit signal 7 to stop the second unit. The emitting of signal H by control 2 to re-connect the first unit 10 to control 1 also causes the second signal B to activate control 2. In a second embodiment (Fig. 2, not shown) the circuits are scanned to detect the existance of a signal B. The detection of such a signal stops the scanning process, and enables the unit to be controlled by control 2. Further units controlled by control 3 are connected by the scanner to control 3 when the first unit has to be re-connected to control 1.

The magneto casing 11 is extended to house the coupling members and is rendered oil-tight by packing 40. Angular displacement between the members 12, 14 is limited by lugs 25 which engage in arcuate recesses 26. The springs 17, 18 are wound by arresting the member 12 by means of pawls 30, which are pivoted between ears 29 on the member 12 and are adapted to pass through slots 36 to engage notches 35 in a member 33 fixed to the magneto frame.

Adjustable springs 44, fitted in grooves in the ears 29, may be used to throw the pawls into engagement with the notches at a predetermined speed. The provision of notches on both sides of the member 33 facilitates the adjustment necessary if the direction of rotation is to be reversed.
