Title: Improvements in or relating to spring suspensions for vehicles
IPC: B60G11/04
Filed: 1920-09-27
Abstract: 173,583. Palladium Autocars Ltd., and Smallwood, H. F. Sept. 27, 1920, Laminar springs; spring shackles.-In a spring suspension for vehicles, two cantilever springs are fulcrummed one above the other and at or near the middle to a frame, which is trunnioned to the chassis so as to move in a vertical longitudinal plane about a fixed axis situated between the springs, and are pivoted at one end to the wheel axle bracket above and below the centre line of the axle and connected at the other end to the chassis. As shown in Figs. 1 and 3, the springs B are secured by caps E to a frame C which is pivoted on a trunnion C<1> carried by a chassis bracket C<2>. The springs are pivoted at one end to pins a<1> on the axle bracket A<1> and, at the other end, the lower and upper springs are pivoted respectively on a pin d<3> at the lower end of a link D<2> and on a pin d<2> which pivotally connects the link D<2> to a shackle D trunnioned to the chassis at d<1>. The trunnions C<1>, d<1> may be formed on shafts extending transversely across the chassis or, as shown in Fig. 3, the brackets C<2> on opposite sides of the chassis may be connected by a cross-rod C<2>X. The leaves are formed at the centre with inter-engaging spherical projections and recesses. The projection on the top leaf of the upper spring engages a recess in its cap E, while the recess in its bottom leaf engages a stud c on the frame C, a similar arrangement being provided for the lower spring except that the stud is on the cap E and the recess in the frame C. The beds c' of the springs on the frame C are rounded. The ends of second leaf of each spring B are extended and curved downwards as shown in Fig. 1, so as to enable the springs to function in the event of fracture of the lower or master leaves. As shown in Fig. 3, the caps E are flanged to extend over the sides of the springs and fit over bosses CX on the frame C, but in a modification the flanges on the caps are dispensed with, lateral movement of the springs being prevented by the holding-down bolts and by upwardly and downwardly extending flanges on the frame C. The shackle D may be resiliently connected to the chassis as shown in Figs. 9 and 10. The shackle D carries bolts d<5> which slide in a member D<5> against the action of adjustable coil springs D<4>, other bolts d<6> carried by the shackle serving to guide' and limit the movement of the shackle relatively to the member D'.

Title: Improvements in or relating to bucket grabs
IPC: B66C3/06
Filed: 1939-10-11
Abstract: 535,033. Grabs. PAGE, M. W., FLOOD-, and WESTWOOD & CO., Ltd., J. Oct. 11, 1939, No. 27670. [Class 78 (iv)] Comprises an improved disengageable coupling between the lower purchase block and the lower crosshead in grabs of the type in which the buckets are pivotally suspended from an upper crosshead and are linked to a lower crosshead which is moved to and from the upper crosshead in the closing and opening movements of the buckets, the lower and upper crossheads carrying guides which telescope during the movement as described in Specification 322,908,[ Class 78 (iv],and also guide the lower movable purchase block. Fig. 4 shows the position of the parts at the moment the open grab has been lowered into contact with the heap of material. The first step is to lower the block 2 in the guides 3, 5 by paying out the rope 22. During the lowering the pin 11 trips the lever 9 and enters the notch 12. The lever 9 raises the pivoted lever 13 momentarily during this process and the latter then falls by gravity so that the roller 15 engages behind the lever 9 and locks it to the pin 11. Hauling in the rope 22 till the lower block 2 again reaches the position shown then raises the lower crosshead 6 to close the buckets. In this position a counterweight 17 bears against the tail 16 of the lever 13. When the grab is lowered on to the dump heap and the rope 22 slackened the lower block falls and takes up a slight clearance between it and the crosshead 6. This lowers the pin 11 to partly relax the pressure between the pin and the lever 9. This allows the counterweight 17 to raise the lever 13 and thus release the lever 9 so that the pin 11 can pass it when the rope 22 is again wound in. The crosshead 6 is thus left behind and the buckets open under the weight of the load, leaving the apparatus ready to be lowered once more on to the loading heap. For dumping while the buckets are in suspension, a lever 19 is used to raise the lever 13.
