Drivers Uniforms.
P. DONOVAN (Wrexham).—In reply to your query as to where you can obtain drivers' and conductors' uniforms, r-ou will, of course, realise that many firms are quite willing to cater for this class of work, and the advent of -notorcalo companies, throughout the country, has given a onsiderable impetus to this branch of the outfitting trade. rhe Pioneer and the Vanguard Motorbus Companies were -esponsible for large orders of this kind. The General 4otor Cab Company, of London, set its seal on a comnendable fashion, by clothing its drivers in the smart and vorkmanlike blue uniforms which arc now such a familiar .eature in the streets of the Metropolis. If you require t number of names of such firms as are accustomed to this !lass of work, and to whom you can write for prices, we will send you a list, but, in the meantime, we understand hat the major portion of this business, so far as motorcab :ompanies are concerned, has been and is being done by dessrs. H, Lotery and Company, of 4-8, St. Mary's Street, Vhitechapel, E.
Iralce Linings.
GEORGE HELMSLEY (Leeds).—Your letter has duly been eceived by us, although addressed in error to " Roseberg itreet " instead of " Rosebery Avenue." The service you utline is clearly an extremely hilly one, and we should trongly advise you to pursue your original intention of mployinga suitable brake lining for the brakes on your hree-ton machine. In our issue of the 7th May last, we ublished an interesting account of " Ferodo," the efficient roduct of the Herbert Frood Company of Chapel-en-le'rith. We then had occasion to notice, amongst other seful properties of this material, that its action was smooth nd regular, and that it showed no bad effects from exces'.ve heating or other ill-usage. The London motorbus cornaMes, and most of the London underground railways, are ery large users of " Ferodo." You should write to the rcxxl Company for prices.
You will also do well, while you are interested in this .ffiject, to obtain samples and prices from Brown :rothers, Limited, of Great Eastern Street, E.C., of the
Raybestos " material, which is composed of asbestos inter. .oven with brass wire. We have heard very good accounts
the behaviour of this material.
realm for Gear Silencing.
G. PAITL ELWORTH (Oxford).—We are inclined to be 7eptical as to the satisfaction you will achieve in the direcon of silencing noisy gears by the use of specially-prepared ibricant. There is, of course, no reason, however, why m should not try the experiment yourself; exhaustive ials were undertaken with grease-curn-sawdust mixture several of the leading omnibus companies, at the time .hen the Carriage-Office authorities at Scotland Yard were !jectingso many new chassis, on the score of " undue gearxt noise," some two years ago, but the results were di pointing. The friction inside the gearbox was found to
be materially increased by the employment of such a viscous type of lubricant, although noise was reduced.
As a rule, such preparations consist of some reliable quality of thick grease, and into this is introduced a small percentage of g-raphited wood fibre and flake graphite.. We believe the Joseph Dixon Crucible Company of America makes a speciality of such a lubricant, and that it uses a special fibre prepared from kiln-dried, straight-grain, cedar wood. Its English office is at 26, Victoria Street, Westminster.
You should have very little difficulty in procuring a few tubs of this kind of grease from any of the better-known oil and grease factors. Gear-silencing grease is extensively used on the electric-motor gear reductions on tramcars.
Fuel Deodoriser.
GABOW'NER (Wandsworth).—The apparatus for which you are enquiring must be that known as the Barnes' deodorizer. The device was patented nearly two years ago. We have noi personal experience of the efficiency of the arrangement, but, for the information of yourself and of others who may be interested in the matter, we give a few particulars of the deodorizer as supplied by Barnes and Pocock, Limited, of II, Queen Victoria Street, E.C.
The arrangement consists of a circular form of filter which is built up of two concentric perforated rings. These two
rings are lined with fine-mesh gauze and the annular space between them is filled with a special preparation, through which the liquid fuel is caused to pass on its way to the carburetter. The percolation of the spirit through the enclosed preparation is claimed entirely to deodorize the liquid, without causing any deleterious effects upon it as a fuel. The device is also designed to act as a water and dirt collector. One charge of the special preparation is stated to be sufficient for a distance of from 2,000 to 3,0(5) miles, although this must, in the nature of things, depend upon the horsepower of the engine, the weight of the car and other characteristics of the vehicle upon which it is employed. The listed price of a complete deodorizer is 55 shillings, with refills at five shillings each.
