Title: Improvements in motor lorries fitted with tilting platforms and with gear for hauling loads thereon
IPC: B60P1/10
Filed: 1925-01-26
Abstract: 228,200. Tenner, A. [Firm of], and Ballert, O. Jan. 26, 1924., [convention date] Interlocking and guarding against wrong movements.-In a motor lorry intended particularly for transporting refuse, gear for tipping the platform and for hauling a container or vehicle U thereon is mounted directly on the chassis, and either the tipping or the hoisting mechanism may be coupled at will to the driving shaft by means of one lever acting on a sliding rod, the lever also controlling a bevel reversing gear. The worms a', b<1> for tipping and hoisting respectively are driven from the engine through shafts d, c and gearboxes C, D controlled by the lever R. For tilting the platform, the lever R is moved to the left, actuating a rod F and lever T to connect a worm a<1> and shaft c. The lever is then raised or lowered to connect shafts c and d. When the platform is in the position shown in Fig. 6, a recess in a quadrant H is opposite the end of the rod F. The lever R is moved to disconnect shafts c and d, and is then moved to the right to disconnect the tipping-gear and connect shaft c with the worm b<1> of the hoisting gear. The hoisting gear can only be driven when the platform is in this position. The platform may be tilted further, as shown in Fig. 4, for emptying the vehicle U through an end door. The tipping gear is disengaged automatically by a stop-lever after the tipping of the platform.

Abstract: 450,862. Fire-extinguishing; inertiaoperated devices. GRAVINER MANUFACTURING CO., Ltd., First Avenue House, High Holborn, London, and SALMOND, H. M., Briarwood, Fareham, Hampshire. Jan. 24, 1935, No. 2369. [Class 47 (ii)] [See also Groups XXVI, XXIX, and XXXVII] An inertia - operated mechanism for controlling safety devices, such as fire-extinguishers, switches, or valves, for vehicles or aircraft, comprises a pendulum 10 which is suspended by a universal joint from a spindle 11 and has an enlarged head 12 with a crater-shaped surface 13 and a central bore, the diameter of the crater being about half the suspended length of the pendulum. The surface is engaged by a stud 14, having a conical upper end with rounded edges, carried by a lever 15 pivoted on a spindle 16 which is arranged at right-angles to the axis of the pendulum and in the plane of engagement between the stud 14 and surface 13. The lever 15 is pressed by a spring 19 which is adjustable by rotating a boss 17 with an index plate 17<a>. Preferably, the pendulum 10 and lever 15 are about 1¢ inches long, the head 1 inch in diameter and ¢ inch thick, and the crater inch in diameter with its surface inclined to the horizontal at an angle of 15‹. With these dimensions and a suitable adjustment of the spring 19, it is stated that disengagement of the stud 14 and surface 13 is prevented when the device is vibrated at amplitudes of from À05 to À15 inch at a frequency coinciding with the natural frequency of the pendulum, but is permitted when the device is subjected to decelerations of the order of 3 to 4 g, where g represents the acceleration due to gravity. The index plate 17a is calibrated in values of g. The device may be tested successively on whirling and vibrating tables. The coacting surfaces of the head 12 and stud 14 may be reversed. As shown, release of the stud from the pendulum allows a spring contact-arm 21 to engage a contact 20. Normally, the arm 21 is held open by an eccentric 22 such that the reaction of the arm 21 acts through the axis of the spindle 16. The device is reset by means of a knob 16<a> on the spindle 16.

A hydrodynamically supported head, embedded in an epoxy-resin pad 20, is supported by a pair of cantilever springs 22, Fig. 2 out of the viscinity of a drum surface 12 when the drum is at rest and is dragged into transducing relationship with the drum by virtue of the drag of the boundary layer of air on the underside of the pad 20 and its impact on the leading edge of the pad, in combination with the angled relationship of the cantilevers 22. The approach of the pad to the drum is limited by the resisting air-bearing force between the pad and drum. In a modification, Fig. 7, the cantilevers are joined to the leading edge of the pad, and with a deflector 34, a low-pressure region is created on the downstream side of the cantilevers and the ambient air pressure A acts to augment the other downward dynamic forces. A similar arrangement, Fig. 9 may be used for pairs of heads operating on adjacent discs. The pairs of cantilevers may also act as the leads to the head windings.
