A Resum6 of Recently Published Patents.
The. type of body for a commercial motor vehicle, which is described in specification No. 150,856, is ranch in demand in colliery districts, and in the induatrial areas of Lancashire and Yorkshire. It is not therefore a matter for surprise that it originates in Yorkshire, in which county the two patentees, O. II. Roe and T. Tate) reside. As described and illustrated, the body is made up of three compartments, although the number may, at course be varied, and the patent, is nob limited in its application to a vehicle of any precise number of divisions.
Two longitudinal runeers ere mounted on the frame of the chassis. Aceoes these are laid bearers, in number according to the number of compartment& into which the body is to be divided. In the present case, with three compartments, there are four such bearers. Bearings on these bearers acecen2noclate longitudinal
tubular rumens. They support, by means of inverted U-shaped brackets, frames of channel steel. The compartments are arranged to tip to either side of the chassis and are fitted with the usual type of swinging door at each end to facilitate the discharge of the contents. To the esederside of the compartments are fitted brackets and rollers, and the latter ran on the inside of the channel steel frames. Screw and nut mechanisru is provided, one set for each comparte meat, by the use of which any compartment may be moved to either side of the lorry. This mechanism may be controlled from either side of the vehicle. It does not move, however, so far as to overbalance. The actual operation of tipping the compartment is effected by another screw-and-nut gear running the full length of the chassis, and actuating. through bevel gearing, vertical screws which tip each compartment. All the vertical screws are worked by means of the one longitudinal shaft, and the three compartments, may be tipped either all together or separately. If the latter, then the gearing which effects the tipping of the two which are not to be tipped. must be disconnected, for which purpose each set of bevel gears is fitted with a clutch. which can be manipulated from either side of the chassis by means of a hand lever

Other Patents of Interest.
Alldeys and Onions, Ltd., have patented, in specification No. 150,768, a form of carburettor which appears to be particularly suitable for use with twin fnelseof which one is for starting, and the other, which may be heavier and lose volatile, for ordinary rum/ling. The carburetter is of the type in 'which the jet orifice is regulated by a, tapering needle, which is lowered into, or raised from, the orifice according to the demand for fuel. In this case the movement of the 'noodle is governed by the suction of the engine; this takes effect on a valve which is attached to the' needle. The seine valve also controls the amount of air which is admitted to the engine. The jet itself is situated in quite a small choke tube, leading from an aer inlet pipe of correspondingly small size. The rich mixture of air and fuel thus formed is taken along a coil of piping which is placed within the exhaust box of the engine, and is duly heated thereby, before it passes to the main mixing chamber of the carburetter, this being situated above the floating valve to which we have already referred.
Ni. 150,796 refers to a detail of the well-known portable gas-producing plant which was invented by IA.-Col. D. J. Smith, who is also responsible for the present patent. In order to reduce the weight of the plant, he makes the refractory lining of the combustion chamber much thinner, keeping up the strength either by making it of re-inforced material, or winding it with wire or thin strips of metal. -Further, in order that the outside of the apparatus may be kept as cool as possible, a second annular chamber is arranged round this lining, and the incoming air to the producer is caused to traverse this chamber on its way to. the furnace:
An ingenious two-speed epicyclie gear, which is meant to he moue/bed in the rear axle case of a motor vehicle, is described in No. 150,868, by J. Sutton Withers. On the inner ends of the live axle driving 'sheik/tare inometeklethe!usual sun wheels of the differential gear. The outer case of the differential, however, instead of
carrying the crown bevel or worm wheel of the final transmission, is drilled to accommodate three pins which form the bearings for the planetary pinions of an epicyclic gear. These pineena mesh, on the one head with a sun, wheel, which is integral with the main crown bevel wheel, and on the other with aninternallytoothed gear which is slicleable eu the direction of its axis. In one of its extreme positions it engages with a wheel which is secured eo the axle case, and is thus held stationary : in the other extreme position it engages with a. clutch wheel on the crown bevel. In the third, or mid position, it is free of both these wheels. Them are thus provided two speeds and neutral.
No. 150,767 is by•Mr. S. S. Guy, and relates to his well-known type of V engine. It has mainly to do with a detail
of the construction of the cylinder heads, which are, as before, removable without interference with the rfiechanism of the valve gear. The valves are operated from the camshaft, by rockers, and the whole of the valve gear, while being enclosed, is nevertheless in communication with the interior of the crankcase, and thus has the benefit of the oily mist which is constantly floating about that chamber.
No. 150,794, by M. K. Ingoldby, refers to a previous, construction of hydraulic tranandesion gear. The present invention, is concerned with the method of obtaining, with the previous construction, a direct drive on top.
The method of starting acre engines by using i the power of a motor vehicle engine s referred to in a patent by G. Holt Thomas; in which the inventor describes a safety gear. The specification is numbered 150,840.
In the silencer, which is described by A. Castete, in specification No. 150,897, a spherical cdsing contains a freely revolving series of vanes. The exhaust gases, in passing through the silencer revolve these vanes, which operation conduces to the silencing of the noise made by issuing ga
