Abstract: A trailer drawbar has a housing with a cylindrical outer chamber and a cylindrical inner chamber separated from one another by a stop. First and second compressible bushings respectively fit in the outer and inner chambers. The bushings have aligned bores. A rod extends through the bores in the bushings. One rod end contains an annular base, which abuts the first bushing, and a drawbar eye. The other rod end is threaded. An annular seal is positioned on the rod adjacent to the second bushing. The first bushing has a length and compressibility such that the seal remains entirely within the inner chamber when the first bushing is compressed to a pre-determined level. The second bushing has a length and compressibility such that the first seal is not located completely inside of the inner chamber when the second bushing is compressed up to a second pre-determined level.

Abstract: Coupling devices for different landing gears of aircraft are disclosed. In one embodiment, a coupling device for coupling to a landing gear of an aircraft may include a first landing gear adapter that is designed for coupling to a landing gear of an aircraft of a first type. A second landing gear adapter that is designed for coupling to a landing gear of an aircraft of a second type is provided. The second type is different from the first type. A change device is coupled to the first and second landing gear adapters and designed such that optionally the first or the second landing gear adapter can be positioned in an operating position, or location of the coupling device, suitable for coupling to the landing gear. A plurality of second landing gear adapters may be provided and may one at a time be moved into the operating position in a pivoting manner.

Abstract: Line holding apparatus including a tubular mounting member secured in a substantially stationary position to a support, a cap which fits against the end of the mounting member spaced outwardly from the support, and a spring yieldably biasing the cap against the end of the mounting member. An elongate arm secured to the cap extends upwardly therefrom to confine and hold a portion of a cable when the cap is held against the mounting member. A lip on the cap engages side surfaces of the mounting member to inhibit lateral shifting of the cap. A member attached to the cap engages a notch on the end of the tube to inhibit rotation of the cap and arm. A force applied by the line against the arm which is greater than the biasing force of the spring releases the arm in almost any direction in which the line force is applied. An adjustment device is provided for increasing or decreasing the tension force of the spring.
