Pivoted Hook Patents (Class 213/179)
  • Patent number: 8915385
    Abstract: A coupler head for a coupling arrangement is shown, which coupler head includes a coupler head housing (6) extending in a longitudinal direction from a first end (6a), attachable to a drawbar, to a second end (6b), which is arranged to carry a coupling interface between coupled rail vehicles, which coupler head housing houses mechanical coupling components (8,9) effective for automatic coupling to the corresponding components of a connecting coupling arrangement. The coupler head is characterized in that the coupler head housing has at least one notch (11, 11?) for a predetermined and primarily axial compression thereof with absorption of energy from a deforming compressive force that is applied to the coupler head in the longitudinal direction thereof. The coupler head has preferably at least one notch (11, 11?) for a predetermined folding of the coupler head housing.

  • Patent number: 4825778
    Abstract: A rail car is adjustable in length to accommodate the mounting thereon of cargo containers of various lengths and widths, such as the presently employed 20 foot, 40 foot, 45 foot and 48 foot lengths and 96 and 102 inch widths. Length adjustment is effected either by forming the rail car frame in two telescopic end sections, or by providing an extensible coupling tongue on one or both ends of the rail car frame. The rail car also may incorporate a collapsible fifth wheel connector for the king pin of a cargo container trailer chassis to accommodate transport of a trailer-mounted cargo container. The rail car also includes structure by which it may be manipulated by external lifting equipment to stack a plurality of the rail cars one atop another, either for stationary storage in a rail yard or for transport in a train to another location.

  • Patent number: 4771719
    Abstract: A standoff bracket arrangement, for securing boats to a landing structure, is provided having one member secured to the boat and another member secured to the landing structure and a gravity-actuated latch for cooperatively connecting these two members. Initial sliding engagement of the boat member with respect to the landing structure member causes the latch to be upwardly displaced, providing free access to a slotted portion in one member for a latchable portion in the other member. Further insertion of the latchable portion into the slotted portion permits the latch to be downwardly displaced under the influence of gravity to prevent removal of the latchable portion from the slotted portion. The latch also includes a cam surface slidably engagable by the latchable portion when within the slotted portion to cause downward displacement of the latch which also prevents removal of the latchable portion.

  • Patent number: 4232794
    Abstract: A car coupler includes first and second complementary coupling members which are respectively attached to cars by means of drop pins about which the coupling members can rotate horizontally. The first coupling member (female) includes an elongated coupling bar which is supported by a frame allowing 360.degree. of access thereabout. The second coupling member (male) comprises a frame having a latching lever and a locking lever with axes approximately parallel to the coupling bar. The latching lever forms a latching hook having a nose portion which pivots behind the coupling bar when the latching lever is pivoted to a coupling position. The nose portion defines a notch which is engaged by a locking hook of the locking lever on the other side of the bar for locking the latching lever behind the bar.
