Notices of Useful Specialities from the Factory: and in the Showroom.
We have received an inquiry from a well-known commercial-motor manufacturer, who is anxious to get into touch with the firm of irown and Walling, of Southampton Buildings, who, some four years ago, manufactured a paraffin carburetter known as the " B.W." If any member of the firm of Brown and Walling will communicate with us, we shall be pleased to place him in touch with the inquirer.
Taxi Accessories.
A copy is to hand of the new accessory list issued by Oylers, Ltd., 35, New Cavendish Street, W. The "Skew" security bolt factored by this company possesses a great selling point in that the shape of the head follows the contour of the rim and enables the bolt to grip the rim firmly. The ends of the rubber covering are also tapered away, so that it is an unlikely thing for a sudden break to occur ; further, the danger of the tube's wearing is minimized. A feature is also made in the list of tire pumps and levers, and also of pressure indicators and accumulators, these latter being specially designed for car-lighting equipment.
Drummond "Repeats."
We are informed that several repeat orders have been received by Drummond Bros., Ltd., Guildford, from Government departments for its well-known 3i in. centre lathes. The electric-motor drive, which is a feature of the latest Drummond design, seems to be becoming increasingly popular ; many orders are being received specifying this electric drive. We reproduce on this page a photograph showing part of the latest official order. Amongst engineers these small lathes are maintaining an already valuable reputation, and big fields exist for this type of machine amongst the owners of one or two small delivery vans, who are, with its help, enabled to effect many small repairs. Thermo-Electric Pyrometers.
The Cambridge Scientific Instrument Co., Ltd., makes two types of thermo-electric temperature indicators, the ordinary form of which is manufactured for work in the laboratory or workshop, while the wall type of instrument is intended for indicating the temperature of hardening and annealing furnaces, etc. Both instruments were lately to be seen in use at Olympia.
Dynamo Set for Car Lighting.
Brown Bros., Ltd., of Great Eastern Street, B.C., has issued a new catalogue dealing with the " Brolt" car-lighting system. The complete appliance is the outcome of many years of experience, for the makers were amongst the earliest in the field of dynamo electric lighting for motorcars. The catalogue gives technical details in as simple a manner as is possible. Useful half-tone photographs and line drawings amplify the text. The instructions for working are clear and concise, and no difficulty should present itself when handling the plant to the every-day driver who gives the instructions five minutes of attention.
The system is entirely enclosed and rainproof. The switchboard is made of metal throughout. and it is fitted with a combined ammeter and voltmeter, together with a switch and visible indicator. A further interesting feature is the tell-tale indicator with a red lamp which lights up should the tail lamp go out of action.
Although a refined system of lighting such as this is does not directly appeal to users of heavy commercial vehicles doing a large amount of heavy road running, it should be of great interest to users of the numerous highly-finished commercial chassis for light goods. where a showy and artistic appearance is a valuable asset. Brown Bros., Ltd., will forward particulars of this system to interested users.
A time-saver in garages, The Garage Pump.
It is somewhat surprising the amount of time that is wasted, even in what are, in other respects, wellequipped garages, in the pumping up of tires. This remark is caned forth after an examination of the portable three-throw pump for garages made by Ross, Courtney and Co., Ashbrook Road, Upper Holloway, N. This pump is adapted to be driven by hand or by power, a h.p. motor being sufficient to supply a power-drive if required It is intended to be run at a speed of 250 r.p.m., and, when used in big garages the makers advise the installation of a compression tank and retainer, from which air can be taken direct, and the pressure maintained by means of the pump. A Portable Workshop Forge.
The steels used in the modern shop demand appliances for their working which represent a distinct edva,nce on the methods of a few years ago. The Sturtevant Engineering Co., Ltd., has fully grasped his fact, arid is placing on the market a range of selfontained forges which are particularly well suite3 o motor workshop use. The forge, illustrated hereith, is powerful enough to heat a moderate-sized iece of material, either as casting, forging or press ' g, to any reasonable temperature. It can be operated and used by the youngest apprentice withut trouble. The motor, fan, switch and transformer are all so placed as to be well protected from danger.

A Heavyweight Saw.
Modern machine saws are indispensable in works-. where automatic and semi-automatic repetition machines are employed. To feed, say, a capstan lathe with metal blanks, without the wastage of steel which so often occursdue to slipping and bending of the saw blade—a substantial and well-designed quickaction machine is useful. The saw made by E. G. Herbert, Ltd., Leeenshulme, Manchester, and illustrated herewith, is a fine specimen of a modern tool.
intended for this and other similar purposes. • The saw blade is held clear of the work on the return stroke. The fall is arrested by an oil-dashpot. A quick-action swivel vice is supplied with the machine, together with an adjustable device for stopping the work at the end of the cut, or near to the end, if this should be desired. The speed recommended for effective work is 125 r.p,u1., and the net weight is 560 lb.
Saws 4-in.-diam. round steel in 10 minutes. A One-lozk Adjustable Reamer
The workshop practice of to-day calls for greater, and ever greater accuracy of workmanship. Parts must be interchangeable. Strange phrases are be coming household words. "Running, sliding, slip, tight, push, drive," all these represent different sizes and fits which the latter-day workman is continually called upon to produce. Few tools are so useful in effecting such work as a reamer, if it be a good, adjustable reamer. Wear can be taken up, cutting edges can be ground, and, when accurately set, work is turned out to the required size. with almost monotonous regularity. Such a tool is the V.S.M. adjustable reamer, made by Vickers, Ltd. The adjustment on this accessory is: infinitely variable within the range of any particular size, and, when once locked, the reamer is as rigid as. a solid bar of metal.
