a tire with Ftribberine or other similar compounds. The tire is secured to the rim by an inner band which is divided into sections, each section being held in place by security bolts. Two of the security bolts are hollow, and they are preferably at opposite sides of the tire. One of these is used for inserting the Robberine, while the semnd is used as a vent-pipe.
When filling the tire the compound is forced in at the bottom, and the air escapes from the vent-pipe at the top. This vent-pipe consists of a tube inserted through the hollow security bolt and extending outwards to the tread of the tire so as to ensure that all the air is displaced from the tire. When the tire is filled the two stop-cocks are closed and the tire is laid horizontally until the composition sets, A. A. SCOTT,. No. 11,707, 1915, dated 14th December. 1914. The accompanying drawing shows a side elevation and plan of a three-wheeled motor vehicle in which the front steering wheel is in line with one of the rear..driving wheels. The chassis is composed of two triangulated side structures which are tied together by straight and diagonal cress-ties, The front wheel is mounted on a double triangular structure which is pivoted on a horizontal bar at the front of the chassis and this structure is connected by spiral springs to some other part of the frame, so that a bell-crank lever effect is obtained.
The rear wheels are mounted on a single axle carried by radius rods; and this axle also is connected to the main frame by tension springs. The drive is taken from the engine by a shaft mounted in the interior of the adjacent radius rod and transmitted to the road wheels in any desired manner. colmecting rods of a petrol engine, without necessarily using a built-up crankshaft.
The crank-pin is hardened to form one race, and the outer race is constituted by or fixed in the big-end. The outer races are slipped ever the crank-webs and mounted in position arou»d the crank-pin. The rollers themselves are of a length not more than half the length of the crank-pin so that they can be inserted laterally into their races. The space then remaining at the side is filled by a split cellar.
J. E. WILD and J. R. TOGNARELLT, No. 639, dated 15th January, 1915.—In this carburetter an annular float-feed chamber is provided around the base, and a large number of jets extend from the top of this chamber inwards to the mixing chamber, the fuel being supplied to the jets by a felt pad or other material which will soak it Up. The air inlet on the left-hand side is controlled by a vertically-sliding shutter which is shown in its uppermost position. Within the mixing ehamber there is provided a sleeve which can be turned to throttle the air pply, and which is also capable of a slight axial movement, upwards or downwards, so as to open or close the fuel jets to any required extent. The air inlet is shown as fully opened, while the jets are half closed.
The bottom of the valve is shaped in the manner shown to give a smooth and steady current of air over the jets.
The control is effected by means of a spindle on the sleeve extending downwards through the float-feed chamber, and various details of the construction and packing to ensure fght joints are fully described in the specification.
