Further Notices of Useful and Interesting Specialities Now Being Exhibited at Olympia.
More Lubricants.
Price's Co. (Pricers Patent Candle Co., Ltd.), of Belmont Works, Battersea, S.W., is represented at Olympia by a good show of lubricants for all types of steam,. gas and petrol engines, together with a range of insulating oils for transformer oil brakes, switches and other electrical purposes.
The Hoyt Metal Co.'s Specialities.
The Hoyt Metal Co. (of Great Britain), Ltd., is a live concern making a speciality of die-cast bearings. These are cast on a machine patented by the company which claims that the natural skin on these castings makes them of much value in motor work. The work, the company guarantees, is cast true to size to within .0001 in. by this method.
More of the Wrigley Worm.
An increasing business is being done by E. G. Wrigley and Co., Ltd., Foundry Lane Works, Birmingham, in the drills, milling cutters, reamers, hobbing cutters and other edged tools which form such a large proportion of its output. Opportunity has been taken at Olympia to demonstrate the cutting powers and speeds of the Wrigley drills. Interesting tools on show are the hobbing tools and the Wrigley worms, which were fully described in our issue for the 7th March last, under the heading of " The Birthplace of the Wrigley Worm." We were told that an order for 200 2it in. twist drills was received during the Machinery Exhibition.
Oil and Greases.
The products of the Stern Sonneborn Oil Co., Ltd., of Finsbury Square, E.C., are not unknown to engineers. A product of this company which is not at the moment quite so familiar, but which will, we have no doubt, quickly become usual in the works and the garage, is the " Screwol " soluble oil for use with machine tools in place of soap and water and other lubricants. " Hefty " cuts are curled off on a small centre lathe at Olympia when " Screwol " is used as a lubricant, much to the edification of an interested crowd of observers.
"Sentinel" Manufactures.
An old friend in Alley and MacLellan Ltd. of Glasgow is to be found at Olympia, where a fine exhibit of the famous "Sentinel" valves is to be seen. Between 30,000 and 40,000 valves of all kinds, ranging in size from 2 in. to 66 in. bore are turned out by this company every year. We are told that the valves on view are not specially finished, being taken from stock, and, if this be so, no finer advertisement of careful workmanship can be desired. The valvespindles are of nickel steel, nickel plated, and they possess clean full threads of which the company is very proud ; these are cut by a specially designed machine. Great attention has been paid to the design of all the valves, with a view to overcoming the structural weaknesses possessed by many makes, and a feature of interest is the lip cast on the inside of this maker's flanges which is intended to overcome any possible flange weakness. Lubricating Oils.
High-grade lubricating oils and greases for all kinds of workshop machinery and appliances are shown on the stand of the Vacuum Oil Co. Ltd., of Caxton House, Westminster, S.W. Forced-feed automatic lubricators for the cylinder lubrication of all types of engines are also exhibited, together with lubricators, with ratchet, oscillating-lever, or wormgear reduction motion, working under pressure.
Drop Forgings.
The advance in the art of drop-forging is well illustrated on the stand of Thomas Smith and Sons (of Saltley), Ltd., Birmingham. This company manufactures a complete range of drop-forgings suitable for heavy motor vehicles, and at Olympia some extremely clean specimens are to be seen. The workshop accessories, such as spanners, shafting, collars, hammer heads, carriers, etc., are already well known to engineers.
The Efandem Display.
By far the most interesting exhibit at the Efandem Co.'s stand at Olympia 25 the Johnson friction clutch, which is intended for use with a wide range of workshop components, including pulleys, lathes, woodworking machinery, and so forth. The few parts of the clutch render it simple, yet efficient in operation. We are told that 16,000 have been used on lathe heads by one manufacturer of turret lathes. It. is claimed to be impossible for the Johnson clutch accidentally to become disengaged.
Washing Appliances.
The " Evertrusty" Star vehicle washer, manufactured by Wallach Bros., Ltd., of Finsbury Square, EC., is constructed with a view to avoiding the dragging of heavy lengths of hose pipe when washing down vehicles. This appliance is intended to be secured to the roof or to some overhead girder in the garage or yard. It is provided with a revolving arm, to which a short length of hose is attached. By this means, the pipe is always ready to hand, vehicles can be easily and quickly washed, and the hose drains itself when the water is shut off. All the metal parts of this appliance are constructed of brass, which, so the maker says, is guaranteed not to leak.
At Olympia, Wallach Bros., Ltd. exhibits a comprehensive range of workshop appiiances. An elec trically-driven lathe fitted with many useful improvements occupies a prominent position on the stand, and, close at hand, are shown several high-speed,
portable, electrically-driven drills at work. These tools are capable of drilling mild steel holes up to 1 in. in dia,meter. An important feature in their construction is that no cut-out is necessary.
Tubes and Tools.
Several inquiries have been received at THE COMMERCIAL MOTOR. office recently, asking for names of makers of tubing for use on commercial vehicles. E. Bennett and Son, Ltd.,. of Aldgate East Chambers, KC., is doing an increasing business in this line, and at Olympia a great point is made of the company's copper-pipe work, and of iron, steam, water and gas tubes, all of which are bent, cut and screwed to any particular shape or pattern desired.
The Whittle Belting.:
It is interesting to note that the patent belting manufactured by Thos. Whittle and Sons, Ltd., Warrington, is meeting with approval in many of the most modern and progressive motor-manufacturing concerns. Users include the L.G.O.C., which company is alarge purchaser of the Whittle products. The peculiar construction of this belting enables it to be employed on the most awkward and complicated drives, and in places where the ordinary flat belting is proving satisfactory, existing pulleys can readily be equipped to take the Whittle endless link-grip belt with the everlasting steel centre.
Cutters and Guards.
The high speed of modern cutting tools has rendered their operation doubly dangerous to the worker, and a great field is now open for the manufacturer of safety guards. S. N. Brayshaw, of Huline, has designed a novel guard for this purpose, which possesses two desirable features in that it is at once cheap and effective. The guard, mounted on a rod which can be bolted by a flexible chain and lock nut to any suitable or convenient position, protects the operator from the revolving tool, without in any way obstructing the view of the work in progress. A number of Brayshaw furnaces are shown in operation at Olympia, together with several furnace accessories of great interest. These include an oil-tempering bath and patent salt-bath furnaces.
High-class Measuring Tools.
It has been the avowed intention of the L. S. Starrett Co., Ltd., since its inception, to provide none but the highest class of tools for use in workshops. It is perhaps not too much to say that 99 out of 100 engineers mention the name of Starrett when highclass tools are the subject of conversation. It would be impossible to give, in the space at our disposal, a one per cent. list of the different workshop tools made by this company, but it is enough to say that the spring-nut callipers, which were first manufactured many years ago, still hold their own in face of much competition, as also does the Starrett micrometer, which is by now regarded as a standard measuring tool in workshops all over the -world. Most engineers have in their possession a Starrett catalogue acquired in the early days of their apprenticeship, and, at Olympia, the old stagers will have an opportunity to review early friends, and to become acquainted with the company's later productions.
More Works Extensions.
Messrs. G. Scarnmell and Nephew, of Spitalfields, inform us that their new works, which will be, when Mrnpleted, a distinct acquisition to the heavy-vehicle depots situated in London, are on the point of completion. Separate departments will be provided for dealing with steam and petrol vehicles, and a. specially-trained and expert staff will be employed in each department. Plant has already been installed for oxygen-acetylene welding, together with a cornniete pneumatic plant and a useful selection of the latest machine tools designed for the rapid and accurate production of motor component parts. Messrs. Seammell and Nephew are prepared to carry out any repair large or small on either steam or petrol vehicles in their own works, from steam-boiler work to painting and upholstering.
