Brushes for Engine 'Cleaning.
For the successful and continuous running of an engine, it is, of course, essential that the various working parts should be kept free from dust, grit and an undue accu mulation of oil. For this purpose, the beet method is to employ a cleaning brush. Although only a simple accessory in construction. with no wide choice of design, there are a certain number of cleaning brushes on the market. Some of these are of little, if any, value for the purpose for which they are intended.
It tria,y be contended that any sari of brush will do for engine cleaning, but it must be borne in mind that upon the working of the engine de pends the running of the vehicle, and that if certain, external me chanism is not effectively cleaned, the engine will not work as well as expected. It is far better to utilize a brush which has been designed for engine-cleaning purposes than to turn to account the first brush that comes to hand, which may perhaps have been intended for house decorating. In this respect, we would draw our readers' attention to the repro duction of a composite line illustra tion which we include herewith, of five different brushes manufactured by the Fearless Brush Co., Ltd., 4, gorthwold Road, High Street, Stoke Newington,N. The speciality of this concern is various designs of brushes for cleaning engines. The chief outstanding feature concerning the Fearless brush is the method by which it is manufae tured. The brush itself is constructed upon an iron hook, the size of which is varied according to the type of brush. The bristle, hair, or fibre, as the case may be, is put over the hook and doubled. The hook is then clamped to make contact with the stem of the handle, thus firmly holding the material in the centre. The brush is then bound with strong wire, which is afterwards soldered to form a solid metal casing firmly attached to the handle. By this method of con struction, it is claimed that it is im possible for there to be any loss of bristle except such as may be occa sioned by actual usage. A distinct advantage is that the iron hook employed permits of the head of the brush being set at any angle.
If necessary, the -brush can be thoroughly cleansed by immersion' in any disinfecting or deodorizing liquid., in petrol or any other cleansing medium—it can oven be boiled
—without having a tendency to loosen or cause the bristles to become detached.
Many types of brushes are made, each having a specified use, and we would particularly call attention to one which has recently been introduced for cleaning agrimotor and stationary engines, as well its agricultural machinery. This brush is illustrated herewith. We are given to understand that 252,000 Fearless brushes have been supplied over a period of 18 months to the British military authorities, whilst 15,000 are at present on order for the Royal Flying Corps. These facts are sure evidence of the uS'efulness of Fearless engine cleaning brushes.
A "Pink Form" Benefit.
Although we believe that most of our readers are familiar with the special trading terms offered by the Dunlop Rubber Co., Ltd., to purchasers of its tires and tire accessories for vehicle i used expressly for goods-carrying purposs, we think that there are a number of them who do not appreciate to the full the actual benefit to be gained by filling in the company's " pink form." By returning this form when ordering new tires, the commercialvehicle User derives the benefit of a useful discount.
The principle involved by the company in recognizing the difference in the position of the van or wagon used exclusively for conveying goods and the ordinary touring car is sound.
A .pink form for signing can be obta,med from any agent who deals in Dunlop tires.
Adapting Pneumatics to Miry Roads.
The accompanying diagram illustrates an emergency device, designed by an American firm to extricate light pneumatic-tired vans which have become stalled in the mud. It is described as a mud hook, and comprises a " spud " shaped to slip over the pneumatic tire, being held in position by a strap which passes over the fellee of the wheel, and held taut by a buckle. The hook adiusted against the tread of the tire is perforated by four small rectangular openings, with a central flange parallel with the axle of the vehicle, and slightly curved at the top. There is also a small transverse flange or web on either side. These flanges are designed to dig into the ground and to exercise a lifting effect upon the wheel, while at the same time offering resistance to lateral strains and tendency to slip sideways. Being made from malleable iron, the hook is able to stand up to heavy duty. One hook is attached to each wheel when the latter has become mired. The subsequent rotation of the wheel brings the hook to bear upon the hard ground and gives the wheel the necessary upward lift to enable it to roll forward to secure a purchase. When the vehicle has been extricated the hook is detached. A device of this character should prove useful when a car is being used upon the farm, the load often being adequate to render the vehicle helpless in soft ground.
