Humber Back-axle Construction. Vaporizer for Heavy Oil. Ignition Apparatus. A Built-up Tire.
Ilummu, LTD., and F. T,. BunGzas,. No. 14,687, dated 18th October, 1915.—The object of this invention is to prevent leakage of oil along the driving,ehafts from the differential casing in that .typeof axle in Which the whole of the gearing is removable through an aperture in the casing. A flange or partition is provided in the casing at each side of the removable . cover, and a sliding bush or sleeve fits closely in each of these partitions. The driying shafts extend through these sleeves, but do not bear On them. The inner ends of these bushes are flanged and bevelled, and a spring is arranged to press each of them normally towards the centre of the gearing. A. pin limits the movement.
Similar shields are fitted on the ends of the box tarrying the differential in such a manner that they butt up against the first-mentioned bushes and form an oiltight joint. Any lubricant in the acing, therefore, cannot lealt'.abmg the shaft, but is Wholly enclosed by the partitions, bushes and removable cover,
A. GRAY, J. GASKELL, and W. T. Witaizs, No. 101,111, dated 28th February, -1916.--According to this invention the vaporizer and induction pipe are constituted by the same member. The induction pipe, as illustrated, has a central connection for the carburetter and a connection at each end for the cylinders. A tube extending centrally through this pipe carries the exhaust gases, and radiating fins are attached to this tube to distribute the heat. These fins are so shaped as to form a zig-zag, spiral or other circuitous passage for the gases and are contained within a close-fitting external tube, which fits inside the induction pipe.
An air space is left around this close-fitting tube to serve as a beat insulator, whereby the heat of the exhaust gases is kept within the induction pipe.
IT. R. TAN DEVENTER, No. 13,815/15, dated under Inter. national Convention 1st October, 1914.—In this ignition apparatus a make-and-break is provided within the cylinder. The cylinder wall is shown on the right-hand side of the accompanying drawing and a hracket,bolted on to it carries the operating mechanism for the make-and-break, and also the magneto itself. The tripping mechanism for the contacts is
operated by a reciprocating rod, and comprises a bifurcated lever which engages a finger on the magneto spindle. The operation of the contacts therefore, effects the reciprocation of the armature, but the special advantage of this construction is that the whole magneto can be removed without disturbing the operating mechanism. Another source of current could therefore be connected up and used if desired_
C. A. SeramoNs, No. 14,115, dated 5th October, 1915.—Tires having a tread built up of separate blocks are advantageous in that the blocks can be renewed individually as they be, come worn. The objection that these tires lack resiliency is removed by the construction forming this invention. The resilient blocks are cylindrical in form and are spaced apart by metal retaining plates which axe shaped to bear on a
comparatively large surface of the block. These retaining
plates fit closely between the blocks ;' they are free to move radially of the wheel and to swing about their pivots. When one block, therefore, is loaded and distorted, it transmits the pressure in both directions to the adjacent blocks. The load is thereby distributed over a large number of resilient blocks, all of which contribute to the deformation and resilience of the tire, and assist in sustaining the load.
