Classes 79(2) and 79(5) [Also in Group XXIV] In a motor vehicle having driven front and rear wheels a differential gear DDM is slidably mounted on aligned shafts 1, 3 connected to the engine E and one pair of the wheels, respectively, whereby either the aligned shafts can be connected for drive of only one pair of wheels or all the wheels can be driven with the differential gear interposed between the front and rear wheels. As shown the output shaft 1 of a change speed gear GB has a spigotted non-driving connection with the shaft 3 in a casing C, the shaft 3 being drivingly connected to a differential gear D2 for the rear wheels of the vehicle. The sliding movement on the shafts 1, 3 of the gear DM is under the control of a manual lever (not shown) and the gear DDM comprises output members 28a, 29a and an input member 43. With the gear DDM in the position shown in Fig. 3 the shafts 1, 3 are rigidly interconnected by splines on the member 29a whereby only the rear wheels are driven. Movement of the gear DDM to the right in Fig. 3 causes the member 43 to be clutched to a splined portion 7 of the shaft 1, the splined member 29a to be connected only to a splined portion 8 of the shaft 3 and a splined portion 21 of the output member 28a to be connected to a gear 9 connected by gearing 12, 13 to a gear 14 on the shaft 16. The shaft 16 can be connected by dog clutches 17, 18 to a shaft DS1 drivingly connected to the differential gear D1 of the steerable front wheels of the vehicle and to a power take-off shaft 19. Further movement of the gear DDM to the right causes the gear 9 to be positively connected to the splined portion 7 of the shaft 1 by the member 28a and no drive to be transmitted to the vehicle rear wheels. The front wheels of the vehicle are each rotatably mounted on a stub axle 64 steeringly deflectable about the axis of a pin 66, the pin carrying a gear wheel 67 meshing with a gear 71 of the associated output shaft 69 of the gear D1 and with a gear 72 united with the wheel whereby the drive to the wheel is transmitted.

Title: Improvements in and relating to tippler apparatus for discharging the contents of wagons and the like
IPC: B65G67/00
Filed: 1942-10-05
Abstract: 560,211. Tipping-apparatus. BRITISH REFRACTORIES RESEARCH ASSOCIATION, and MACEY, H. H. Oct. 5, 1942, No. 13924. [Class 78 (iv)] Tipping apparatus, particularly for clay wagons, comprises a counterbalanced frame or platform a mounted for rotary movement between fixed sections of the track about an axis d offset from the vertical plane containing its centre of gravity, the platform being held in its normal position by pivoted lever means thereon, engaging a fixed stop e<1> from which it is released automatically when engaged by a loaded wagon moving on to the platform so that the platform rotates through a complete revolution against the action of a counterweight n which may be adjustably mounted. During the tipping movement the wagon is disengaged from the lever means which then assumes its original position and at the conclusion of the movement re-engages with the stop, permitting the empty wagon to roll off the platform. The invention may be applied to apparatus in which the platform or frame is carried in ring members rotatable on a roller cradle. As shown, the pivoted lever means comprises a catch-lever .g mounted on a post f on the platform a and weighted by a pivoted pawl i which is adapted to be engaged by a projection j on an incoming wagon to rotate the lever g and free it from the stop e<1>. During tipping, when projecting members k on the wagon engage retaining members m on the platform, the pawl i is rocked by gravity from engagement with the projection j and at the end of the return movement, when the gradient of the platform causes the wagon to move forward again, the projection j is clear of the pawl and the pawl and lever g reset themselves. The platform may be brought to rest smoothly by a frictional or other device and rebound prevented by a spring-loaded or like member o engaging a stop p on the post f. The lever and pawl may each be spring-loaded, in which case the pawl is released from the projection j during tipping by means provided at the rising side of the platform. Means may also be provided for arresting a second wagon at the entrance to the platform.
