Details of soirne Ingenious Devices which are on View and which Posses Features of Interest to Motor-vehicle Users TEE Fifth Exhibition of Inventions was opened on October 2nd and remains open until the 12th of this _month. It has grown from a small beginning, the number of exhibits baring improved, as well as the class of the inventions shown. Even, however, in its improved form it would seem a pity that such an exhibition, held in an industrial country like this, which necessarily depends much on its inventions, should not receive greater support from leading firms who have novelties which appeal to traders and to the public.
The arrangements this year are a decided improvement on those of previous years, each exhibit being fully described on a plainly written card which is attached. Those inventions that may be of interest to our readers are as' follow :— N. 221.—A radiator filler cap which enables a driver or conductor to obtain a supply of warm water from the radiator, for the purpose of washing his hands.
No. 224.—An attachment to a carburetter, whereby a fusible element holds up a spring, which, when the element melts, will press on the needle of the carburetter, and so shut off the supply of petrol. This should be of interest to those concerned with motor coaches, as fires usually start in the neighbourhood of the carburetter.
No. 226.—A roof ventilator for coaches. • ,
No. 275.—A clever device for raising wheels from the ground, while changing pneumatic tyres. This device has been shown 'before, but some detail improvements have recently, been made.
No. 279.—A self-cleaning tractor wheel which is intended for working, during wet weather, on ploughed land. It ls well known that,'In such circumstances, spuds or strakes are needed to be fitted to the wheels to afford a grip sufficient to pull a plough. The clogging up of the spaces between the spuds has always been a trouble in such work, but the present invention appears to have overcome the difficulty in a simple manner.
The rims of the wheels are formed in the shape of two cones joining each other at their larger ends, thus presenting a V shape where they hear on
the ground. To these, spuds of ordinary construction are fitted for the Purpose of digging into soft ground. It is true that the spaces between the spuds may become filled with earth, but on meeting the ground again the earth is pushed out sideways, owing to the V form of the rim. The inventor is a practical ploughing contractor.
No. 280.—A new form of anti-dazzle apparatus. This is only in an experimental form, but is of more than usual interest. No. 282.—An electric-heating element which can,' in frosty weather, be inserted in a radiator and, by a small consumption of current, raise the temperature of the water well above danger point. Na. 298.—A metal diaphragm, fitted to a hub mileometer, which prevents grease from finding its way from the hub bearings into the working parts of the mileometer.
Particulars of all these inventions may be obtained on application to the Secretary, Institute of Patentees (Inc.), 39, Victoria Street, London, S.W.I.
