Copies of complete specifications of the patents published on this page can be obtained from the Sales Branch, Patent Office, Holborn, W.C., at the cost of sixpence for each specification.
C. CHALLINER, No. 9896, dated 7th July, 1915.—This specification describes an improvement in the construction Of wheels of the type having spokes of W-section Or hollow tubular section. According to the' invention the' spokes are formed with one or snore radial grooves or depressions extending from near' the hub to near the. outer end or rim of the wheel. A large number of designs are described end illus• trated in the specification.
In • In one case the arms of the W are made sufficiently long to be bent over and welded to the middle.In anotheir ccristruction the limbs of the W are all of the same height and a
separate plate' is riveted to the tops. The 'perspective drawing shows a spoke in which the wings or extensions upon which the rim is secured are formed integral with the spoke
itself. •
A. H. NEULAND, No. 9908, dated 7th July, 1915.--This specification describes a magneto generator in which the current for both lighting and ignition circuits in a motor vehicle is supplied alternatively. A large number of electrical impulses are produced on each revolution, and a few are used for the ignition, the remainder being used for lighting. The drawings show a section through the field magnets and armature. The magnets are circular, and the poles are constituted by diametrically opposite wings. A coil is wound in a slot in the centre of each pole face. The pole faces are toothed, the teeth being regularly spaced except the two adjacent the central slot, in which case the pitch is increased by a half or an odd multiple of a half.
The armature is similarly toothed, and its rotation causes a variation in the flux, as the teeth come opposite one another, thereby generating an impulse in the coil. A simple form of switch' connects the lighting circuit and the ignition circuit alternately with the coil
J. W. MASEELL, No. 13,150, dated 14th September, 1915.— The accompanying drawings show a plan and elevation of a light motor plough which is particularly adapted to turn in a small space so that. afield. can be .ploughed close up to the headland. A single driving-wheel is mounted centrally in the frame and is chain-driven from an engine on the front of the frame. The rear end has steering handles.
A small guide-wheel is adjustably mounted at one side of the driving wheel, and provision is made for attaching this wheel on either side. The plough or other implement which is to be used is carried on a separate frame, and this frame is pivoted above the driving wheel on an upstanding -member. The plough can be arranged centrally, directly behind the driving wheel or to one side as may he desired. Provision. is made for varying the height of the driving wheel.
L. A. PETERSON, No. 11,337, dated 5th August, 1915.— The accompanying drawing shows one construction of an im
proved steering gear. The steering pillar carries near its lower, end, a pinion which meshes with an internally-toothed gearwheel. The pillar itself passes through an arcuate slot in the larger pinion which is of sufficient dimensions to permit the full steering movement. The larger gear is mounted in a casing in which a plate is fitted on top of the gearwheel
This plate supported round the edge, and is pressed for ward by a set screw in the middle so as to bear on the wheel. The pressure exerted by the plate is adjustable, anc it affords certain resistance against rotation of the wheel sc that the steering wheels are more or less locked.
The steering column is preferably made telescopic, so that its length can be varied, and provision is also made for compensating for wear of the gear by mounting the column in an eccentric bush.
