Which of the following most accurately describes the problem?

New Slide-valve Engine. Lancia Brakes. Daimler Spring-shackle Lubricator.

A. B. Moxl.c.rt, No. 27,450, dated alth November, 1913.— The engine described in this specification is well provided for water-cooling. Two flat slide-valved are employed for each cylinder. These valves c.re driven by eccentrics, and work one on the face of the other between water-cooled walls in the cylinder casting.

In the construction illustrated the single aperture at the top of the cylinder is for the sparkioL:-oltt, %%bile of the two

ports at the side ot the cylinder, the upper one is the exhaust and the lower one the inlet.

These ports are surrounded by water-cooled walls, and the passages leading from them are also surrounded by cooling water. The valves and their conduits are enclosed by a detachable case, and above the ends of the valves there is a hollow detachable-cap through which the cooling water passes. lit some constructions the head of the cylinder may be detachable, and the valves may be arranged to slide horizon

tally therein, instead of vertically as illustrated. The invention is described in connection with single and multicylinder engines.

LANCIA AND Co., No. 29,128, dated under International Convention, 11th August, 1913.—The brake drum is provided with two shoes pivoted at one side of the drum and surrounding it in the usual manner. The force for applying the brake is conveyed to a chain lying on the outside of each of the shoes. These chains have a series of flat links pivoted together, and the pivot pins project above the links so that they come in contact with the shoes. The chains thus engage the blocks at a large number of uniformly-spaced contact points.

This construction ensures that the pressure is equally distributed over the whole surface of the brake drum owing to the extreme flexibility of the chain. Irregular wear of the shoes with its consequent disadvantages is thereby avoided. To enable the brakes to be released two tension-springs are connected to the chains, so that normally they are drawn back frout contact with the brake shoes. Means for chain adjua. meat are also provided. H. A. A. J. LELARGE, No. 14,687, dated 25th June, 1913— Iii this carburetter the float-feed chamber is situated vertically above the jet, which is arranged horizontally. The jet is situated in a choke-tube which is shaped as a Venturi tube with the jet nozzle in the throat. Directly facing the nozzle there is a diffuser, which in this case is an elongated cone having the angle at the apex less than 12 degrees. The air is drawn in from the bottom through a network of

flat metal-spirals which extinguishes any flame in the event of backfiring. A loaded non-return valve is provided in the petrol supply-pipe to limit the flow to the required amount..

The situation of the float-feed chamber immediately over the jet ensures that tilting of the apparatus cannot affect, to any serious extent, the pressure-head under which the petrol is fed to the jet.

When the fuel issues from the jet it impinges on the base of the diffusing cone and spreads out laterally. The air acquires a very high velocity in passing through the Venturi tube, and the petrol is violently carried along and immediately atomized..

R. M. S. :MAXWELL and THE DAIMLER Co., LTD., No. 19,641, dated 30th August, 1913.—This lubricator is for the shackle bolts of springs, and the lubrication is effected through the vibration of the bolt. The reservoir for the lubricant is either formed in the head of the shackle bolt or carried on it.

At the bottom of the reservoir there is an outlet leading to a passage in the shackle bolt. The flow of lubricant through the outlet in the reservoir is controlled by a ball-valve which normally rests in such a position as to close it. Vibration of the shackle bolt, however, will tend to throw the ball off its seat, and thus permit the intermittent flow of lubricant.

The cap of the reservoir is screwed into place and, as a precaution against its being lost, it may be anchored by a chain to a bar running across the reservoir. This bar may be arched at the middle so as to throw the chain towards one end, in which position the slack of the chain will rest, against the ball-valve and tend to displace it from its scat.
