ROAD TRAINS.—Burnside and Another.—No. 14,243, dated 20th June, 1907. —This invention has for its object to pro vide means for connecting the adjacent ends of road-train vehicles in order to prevent side oscillation of the vehicles when in motion. The train is provided with the usual steering connecting rods (C) and propelling shaft (D) which extend the whole length of the train. The frames (A, Al) are connected together by rods (E). The rods (E) are connected to bolts (G) supported in brackets (H) carried by the frames (A, A1). Springs (J) are interposed between the bolts (G) and brackets (H). These springs constitute flexible connections for the rods (E).
COOLING ARRANGEMENT.—British Thomson Houston Co., Ltd., and Another.—No. 14,287, dated 20th March,
1907.—This invention relates to means for ventilating or cooling the motor and motor generator on a vehicle driven by what is known as the petrol-electric system. The body (a) of the vehicle is provided with a false bottom (b) in which a pipe (f) communicating with the interior of the motor and motor generator is arranged. The space between the bottom (c) and the false bottom (h) of the vehicle forms a duct through which the air travels on its way to the interior of the motor and motor generator. A fan (h), which is mounted on the engine shaft,
sucks the air from the interior of the motor and motor generator and opposes the draft of heated air proceeding from the cylinders of the engine. Baffle plates (e) are provided under the seats so as to prevent dust from being sucked up by the inrushing air,
ROAD TRAINS.—Manville and Another.—No. 5,870, dated 11th September, I907.—This invention relates to road trains of the Renard type. The locomotor (a) is provided with a petrol or steam engine (b) which drives a motor generator (c) the rotor of which is mounted on a flexible shaft (d) which runs through the train of vehicles and transmits its motion to the driving wheels of the locomotor (a) and trailers (e). The locomotor also carries a secondary battery (g) and electric controller (h) to
gather with the usual automatic, electric control devices used in this type of motor mechanism.
IMPROVED DRIVE FOR MOTOR VEHICLE S.—Renshaw.—No. 7,081, dated 25th March', 1907.—This invention relates to motor vehicles in which the wheels are independently driven. Each wheel is provided with a separate motor which is mounted within the wheel struc
ture and on a central swivelling arm. Each motor consists of four, single-acting pistons working in pairs and set at an angle of 90 degrees within the wheel structure. Fluid pressure is supplied to the motors from a suitable source of supply (diagrammatically shown at j) by means of two supply pipes (k, I) and branch connections (kl, /1). One set of supply pipes (k, kl) conveys the pressure required for the forward movement of the vehicle and the other set of pipes (/, 11) that required foe the reverse movement.
LOCK NUT.—Jennings.—No. 63/1908, dated (under Convention), 7th January, I907.—A nut (B) is provided with a taper ing, reduced portion (b) which is externally screw-threaded and split in one or more places as shown at b1. The reduced portion of the nut is adapted to receive a locking nut (C) the internal thread of which is slightly tapered. It will be seen that, when the nut (B) is screwed into position, the locking nut (C) may be screwed home thus binding the bolt (Al with the nut (B). When the locking ringor nut (C) is in position the ends of the reduced portion (b) are turned up so as to form a flange and thereby prevent the locking nut (C) being entirely removed.
SELF-PROPELLED WATER CART. —Fengler.—No. 5,752, dated 9th March, 1907.—This invention relates to a motordriven water cart. On the driving shaft (2) which transmits motion to the driving wheels (3) of the vehicle a pulley (6) is arranged ; this transmits its motion to a further pulley (7) mounted on the crankshaft of an air pump (El). This pump supplies air under pressure to the tank (10). An elbow (16), which carries a semi-circular distributor (19), is mounted on the roar of the tank (10). This semicircular distributor is provided with a shield (18) and is capable of rotary motion relative to the shield so that a greater or less amount of the distributor may be covered. The angular position cf the distributor is controlled by the driver by means of a hand wheel (12) mounted on, a spindle on which is a spur wheel (13)..
This spur wheel transmits its motion by means of a chain (14) to a spur wheel (1a) carried by the distributor.
