A New Thornycroft Rear-axle Drive. Wyles Plough Improvement. Improved Radiator Construction. Another Front-wheel Drive.
J. McGnimeee, No. 5109 of 1914, dated, under International Convention, 27th February, 1913.—In the construction described in this specification the fixed axle is provided with a pair of arms extending horizontally one above the other, and a hollow sleeve is pivoted in them. Secured to this sleeve
is a stub-axle carrying the road wheel, and extending through it is a shaft carrying a pinion which meshes with a crown-Fear fixed on the inner side of the road-wheel. This shaft is driven through a pair of bevel gears from the live-axle which is mounted inside the fixed axle.
The accompanying illustrations show vertical and horizontal sections, and it will he seen from the latter that the construction admits of a very wide steering lock. The hub is comparatively small, so that the bearings are inexpensive, and the power is applied to the wheel at a point outside the hub, whereby greater strength is secured.
P. J. BUDDERY, No. 8235, dated 1st April, 1914.—The radiator described in this specification is designed to be of great cooling capacity and to be such that, in case of accident or damage, any of its cooling units can be readily removed. In this ease the usual upper tank is used and is connected to the circulating system in the ordinary way. Beneath this tank, top and bottom transverse tubes are mounted in the framework of the radiator and they are connected by the cooling units. These consist of spirally coiled tubes of any convenient section, and they are connected by detachable union joints to the top and bottom transverse tubes, each spiral being independent of all the other spirals. These units may be added to any existing radiator to increase its capacity or they may be used alone. Various details of construction such as the bracing of the radiator frame are described in the specification, but it will be understood that the main feature of the invention is the construction and arrangement of the cooling units.
J. E. THORNYCROITT, No. P29,631, dated 23rd December, 1913.—In this rear-axle-drive a separate worm and wormwheel is provided for each half of the back-axle. The differential is provided with a gearwheel at the front and back ends, each driving a worm-shaft set on the same level as the
differential-shaft and parallel to it. The worms each drive one road-wheel, the two parts of the live-axle being quite separate. This arrangement provides several constructional advantages, one of the principal being that the casing is very simple and can be divided horizontally at the level of the worm and differential-shafts so that they are all easily accessible for inspection or removal without interfering with the main driving axles.
A. WYLES.-NO. 25,974, dated 12th November, 1913.—In this specification there is described a motor plough in which the road-wheels are so mounted that the force of the motor driving them may be caused to raise the frame of the vehicle relatively to the wheels by the reaction of the driving gear. As shown in the accompanying drawing, one of the wheels is mounted on a bell-crank lever pivoted on the frame of the vehicle. The drive is by chain to a countershaft and thence by a pinion to a gearwheel mounted on the pivot of the bellcrank lever. The final drive is by a pinion on to an internal gear on the wheel, this arrangement providing for the gear connection always being maintained whatever the position of the road-wheel may be.
The bell-crank carrying the road-wheel is arranged to be adjustable by hand by means of a screwed tie-rod and sleeve, which locks the bell-crank lever in position. If, however, it is left free the reaction of the driving gear can raise the frame relatively to the wheel within limits determined by the handwheel.
