Title: Suspension means for the driven end of motor-vehicles
IPC: B60G11/04
Filed: 1947-02-25
Abstract: 621,428. Vehicle suspensions. JAGUAR CARS, Ltd., HEYNES, W. M., and KNIGHT, R. J. Feb. 25, 1947, No. 5398. [Class 108 (ii)] [Also in Group XXXI] A vehicle suspension is arranged with the rear axle so connected to a longitudinallyextending laminated spring 20 disposed at each side of the vehicle that the angle between the axes of the propeller shaft 16 and the driven shaft 17a of the differential 17 is kept substantially equal to that between the axes of the propeller shaft and the gear-box shaft 12 as suspension movements occur. By connecting the rear axle to the springs 20 to some point other than the mid-point of the latter, the downshaft 17a would during suspension movements, remain substantially parallel to the tangent to the springs at the point of attachment of the axle. It is therefore possible, by using a scale drawing, to find for any particular combination of shafts and springs an inclination of the differential shaft such that the said angles are initially equal, and to find the point along the length of the springs at which the axle must be attached so that, as suspension movements occur, the angles are still equal, although they have changed in value. The initial value of the angles could be 175 degrees, and the springs so arranged as to be horizontal under normal load; if the axle is connected to the springs at a point one-third along the length of the latter, the angles might each be 171 degrees after the maximum suspension movement had occurred.

Abstract: 349,595. Heating vehicles. HILES J. E., Offa Street, St. Peter's Square, Hereford. Feb. 20, 1930, Nos. 5619 and 34710. [Classes 64 (i), 64 (ii), and 123 (ii).] A motor vehicle is heated by hot water or steam circulated from a water heater through which the exhaust gases pass, and which is secured against the cylinder block of the engine. A water chamber 3, Fig. 2, is provided with upper and lower compartments 4, 5, connected by tubes 6. A damper 14 in the compartment 5 is adapted, in the position shown, to divert exhaust gases from the cylinder block 1 upward through the tubes 6 and thence into the exhaust conduit 13a. When the damper 14 is raised to the dotted position, the water heater is cut out and the exhaust gases are discharged direct. The damper 14 may be in any intermediate position. The water chamber may be filled to the top of the tubes 6, and the steam generated passes through an external tube 7 to a superposed chamber 2, and thence through pipe 8 to a suitable radiator. Water may be used in place of steam as the heating medium, in which case the chamber 2 is filled with water or dispensed with. In a modification, Fig. 6, the exhaust gases from the passage 10 pass over hollow baffles 20 communicating with the water chamber 3. The first Provisional Specification describes a water heater or steam generator which takes the place of the cylinder head water jacket, and is provided with controlling valves to connect it either to the cooling system or to the heating radiator in the vehicle. To facilitate generation of steam, the cylinder head jacket may have parts depending into the combustion space.
