  • Patent number: 4481388
    Abstract: An electrical plug comprises a plug body which houses two or more electrical terminals for connection to electrical cables, at least one of the terminals being conductively connectable and disconnectable from its respective contact pin. To achieve this, the plug body is provided with a tumbler switch, operable to effect electrical contact between a spring contact permanently conductively connected to the contact pins and the terminal by means of a pivoted lever normally biassed out of contact with the terminal by means of the spring contact. The rocker of the switch may be operated manually, but manual operation will be over-ridden on insertion and withdrawal of the plug from its complementary socket. The automatic switch control means comprises an axially slidable pin projecting from the plug body in the "switch on" position and retractable into the plug body on engagement of the axially slidable pin with the front face of the complementary socket, to urge the switch into the "off" position.

  • Patent number: 4479687
    Abstract: The invention provides an electrical distribution system comprising a length of conduit 10 containing a plurality of continuous conductors. Electrical access to the conductors is achieved via a contact plug and a series of spaced entry apertures which are shaped to receive the plug in a particular orientation. Safety door means are provided within the conduit for each aperture and are designed to prevent contact with the conductors by means other than the correct contact plug. In one embodiment of the invention, the conduit is in two parts comprising a support section for securing to a supporting surface, and a wall section containing the entry apertures. The wall section can be connected to the support section at any desired location along its length.

  • Patent number: 3985394
    Abstract: An agricultural tractor has a cab enclosed operator station and a pair of rearward hydraulic coupling elements, one of which is selectively connected to the tractor fluid pressure supply and the other of which is connected to the tractor reservoir by means of a control within the cab. The tractor tows and powers a pull-type forage harvester having three hydraulic cylinders that respectively control the deflection of the discharge spout cap, the rotation of the discharge spout, and the transmission control lever that controls the rotational direction of the feed roll drive. A valve package is removably mounted on the exterior of the cab rear wall and has a pair of inlet lines respectively connected to the tractor hydraulic coupling elements, three sets of hydraulic lines to the respective hydraulic cylinders on the forage harvester, and three control valves for controlling the flow of fluid between the inlet lines and the three sets of outlet lines.
