A spring catch for a door or the like for non- prohibitively retaining the door or the like in a closed position comprises a bolt 15 which is resiliently urged forwardly to an extended position and which includes at its forward or nose end a roller 22 for co-operating with a catchplate or the like, the bolt being formed with a hole or opening 32 which extends rearwardly from the forward or nose end and through which hole or opening a suitable tool can be passed for effecting adjustment of means 27 disposed rearwardly of the forward or nose end and determining the extent to which said forward or nose end of the bolt extends beyond the front of the catch. The bolt is mounted in a body 10 which includes a flat attachment plate 11 provided with holes 12 for attaching the catch to the door and having a hollow cylindrical casing 14 disposed at right angles to the attachment plate and which contains the bolt. The bolt has an end portion 18 of larger diameter than the other end portion 19 to provide a shoulder 20 between which and the rear of the casing is a spring 30. The larger diameter portion 18 is disposed at the front end of the bolt and has two flats to provide sides and is bifurcated to provide two arms 21 between which the roller is mounted. The attachment plate 11 has a non-circular bore 13 which is shaped to receive the roller 22 and arms 21. The portion 19 of the bolt is formed with a bore 25 which contains a screw forming the means 27. The shank of the screw passes through an annular wall 26 at the rear of the bolt and a screwthreaded portion engages a screw-threaded hole 17 in the rear wall 16 of the casing. Thus, rotation of the screw by a screwdriver passed through the holes or opening 32 moves the bolt relatively to the casing to determine the extent to which the roller protrudes through the attachment plate 11. Unwanted rotation of the screw 27 is prevented by a fibre nut 29. The roller is mounted in the arms 21 by a pair of coaxial pins 23 which are rigid with the roller and rotatable in the arms. The roller may be provided with a central annular groove into which the ends of the hole or opening 32 emerge to ensure that the boundary edges of the ends of the hole or opening are not deformed inwardly when the roller engages the catch-plate.

Abstract: 1341471 Tipping bodies and cabs FFSA 19 April 1971 [6 Feb 1970] 21155/71 Heading B7B [Also in Division E2] A fastening device, especially for a vehicle having a tipping body or cab, for fastening a first element 1 which is movable in relation to a second element 2 on which it rests by its own weight, comprises two parts one of which includes a pin 3 adapted to be fastened to the first element and provided with a head 4 and a second part provided with a seat 6 against which the head is adapted to bear, said seat being disposed between two levers 9, 9a pivotally mounted on both sides of the head on a support 7 to which the seat is fixed and which support is adapted to be connected to the second element, the levers in operation pivoting about axes which are parallel to one another and perpendicular to the axis of the seat, said levers being connected by links 12, 12a to a control rod 14 mounted slidably in the support 7 coaxially with the seat, and a push rod 21 slidably mounted in a bore which is concentric with the seat, one end of the control rod being adapted to come into contact with the push rod for moving the levers to releasing positions. When the levers are in the fastening positions the axes of the pivot pins 24, 24a which connect the links to the levers are arranged to be below the axes of the pivot pins 8 and 8a which pivot the levers to the support in an over-centre position and when each lever is in the fastening position there is a gap y between the end portion of the lever and the stud head which can if desired be filled with elastomeric material; the gap is necessary since when the push rod is moved upwardly to move the control rod upwardly against the pressure of a spring 19; the end portion of each lever must first move towards the head before it can move away from the head. The spring 19 is compressed by the initial movement of the control rod 14 since the push rod 21 cannot move until the levers have released the head; the spring also acts to move the levers back to the fastening positions when the control rod is retracted. As shown the control rod is moved upwardly to move the levers to the releasing positions by an hydraulically operated piston and cylinder device. In a modification the holes in the levers through which the pivot pins 8 and 8a pass are slightly elongated so that the levers can move slightly apart, they are however biased towards each other by a spring connecting the pivot pins 8 and 8a.
