Which of the following most accurately describes the problem?

Novel Frame Construction. Carburetter Improvements. Cushion-tire Covers.

Accessible Valve Gear.

F. W. MEAD, No. 23,615, dated 18th October, 1913.—The vehicle frame described in this specification consists of two channelled longitudinal members connected by channelled transverse members. The inner sides of the two longitudinal members extend at right angles to the top but the sides slope

outwards and downwards and are flanged to carry running boards. The inner sides may be similarly flanged.

The inner sides of the two end cross-members slope downwards towards each other and are attached to the longitudinal members of the frame. The trough formed between them may be covered at the bottom by plates which should be detachable. These plates would form the undershield.

Near the front cross-member is an inclined transverse-plate which is attached to the longitudinal members and assists to support the running boards and the shield plates.

The complete frame can be made very stiff and light, and since there am no curves in the metal the cost of production is low.

C. E. JAMES and T. R. Reimarsox, No. 25,324, dated 6th November 1913.—In the construction of the carburetter illustrated in this specification, a choke-tube is fitted beside the float-chamber and has its open end upwards. A conical valve normally closes this opening, which is held up by a spiral spring. The valve is guided by a hollow central stem which constitutes the fuel jet. A series of small-bore tubes is mounted on the air valves; these are of such length that their -open ends project downwards towards the fuel in the central stem and enter it when the valve is drawn downwards by the suction of the engine.

These tubes deliver the fuel at the edge of the air valve, -where it is efficiently vaporized. A pilot jet is arranged so that one end is always immersed in the fuel in the central item, and the other end opens into the induction pipe beyond the throttle valve.

W. S. CLAYEIMIN AND 0. FAR.X.ASCH, No. 29,801, dated 27th December, 1913.—The object of this invention is to provide an improved method of securing a supplementary cover upon a solid or cushion tire.

A fixed and a detachable rim are mounted on the felloe in the usual manner so as to grip the beading on the supplementary cover closely upon the inner core. This core may be of solid rubber or it may be provided with continuous or separate air spaces to form a cushion tire.

The detachable rim is held in position by a series of clamping pieces, each of which has a screwed socket extending into the feline,. A bolt is screwed in from the opposite side of the felloe to engage the socket, and a spring between the feline and the head of the bolt takes up any slackness and affords the desired resiliency to the mounting. The outer cover may be an ordinary pneumatic tire cover, and if desired, old or cast-off covers may be used.

M. BIE,K/GT, No. 28,836/1913, dated under International Convention 14th December, 1912.—In this valve gear the inlet and exhaust valves are placed on opposite sides of the cylinder-head with the camshaft between them. The rocking levers for the valves are pivoted on two rods lying near the respective valves; the special feature of this invention is that these rocking levers are free to slide along their spindles to render the valves accessible.

The rods on which the levers are mounted are supported only at one end, but they are located beside each rocking lever by half-bearings on the upper side, which are mounted on the cover for the valve gear. These bearings also prevent the rocking levers being displaced during normal working. It will thus be seen that when the valve cover is removed it is only necessary to slide each of the rocking levers to one side in order to leave access to the valves.
