James Bartle and Co.

Office and Works : 23Cia, Lancaster Road, Notting Hill, London, W.

We are enabled to illustrate the "Easyweigh " six-ton hydraulic jack, which is a speciality manufactured by this firm of engineers. This jack has been designed with a view to supplying the needs of those who require heavy lifting tackle, and who, at the zame time, are in need of weighing apparatus, a.nd yet are not in a position to put down a weighbridge. The " Easvweigh " jack is ingeniously designed to register the weight which it is lifting while it is in operation. The simplicity of its movernent is remarkable: there are no valves, the liquid being displaced by a hand-operated screw. A small hey can, as a matter of fact, lift the front of a steam wagon with it. It is a jack which we can confidently recommend to all those who are using heavy vehicles of any kind. It also has considerable possibilities in connection with the employment by tramway, railway and other authorities; it can be supplied with or without the weighing gauge.

It is interesting to note that these makers also handle a number of other specialities, amongst which are special towing hooks of the English War Office subsidy pattern, and tipping gear for tip wagons.

The bevel-gear generator known as the " No. 2 D.B.S." will be found of great service in large repair and engineering shops, for cutting teeth and wheels of many descriptions. It need hardly be ea:al that a machine of this kind must be kept continually employed if it is to prove a profitable investment. Most of our readers will, no doubt, prefer to order the required number of cut wheels direct from David Brown and Co., Ltd. On the other hand, municipalities and large firms, who have enough gearwheel work to do, will find that it pays to add the special machine to their existing plant.

A permanent staff of experts is employed by the company, which is pleased thoroughly to enter into the gearing requirements of customers and to prepare designs and specifications well-suited to particular conditions. The important question of the relative advantages of the under nr over-type wormdrive for reae axles is one upon which the David Brown staff is particularly qualified to advise. The drives are made for many differing duties.

Fastnut, Ltd.

Head Office : 115, Newgate Street, London, E.C.

Although many potent lock nuts are manufactured and sold, it is doubtful whether any one of these closely approaches the Fastnut, so far as safety in use and cheapness in cost are concerned. This device is now extensively used by machinery makers and engineers generally. It, has been largely incorporated by chassis makers in their models, especially where it is known that the work to be done will produce undue vibration and shaking. Its Use saves much time in assembling.

The Herbert Frood Co., Ltd.

Works: Chapel-en-le-Frith, Derbyshire. London Office : Upper Rathbone Place, London, W.

Many metals and compositions have been tried from time to time in the search for some suitable material which can be used for the lining of brake blocks and clutches. Few of those have, on the whole, given greater satisfaction in service than has the special fabric-metal composition known as Ferodo, which is manufactured and sold by the Herbert Frond Co., Ltd. Ferodo is used for the lining of vehicle brake blocks by many railway and tramway companies, and motorbus companies in all parts of the world line the clutches and brakes of their machines with it: results are excellent. This material is made up in sheets and blocks, which present no trouble in cutting and working into any required shape. Some of the Ferodo clutch linings have done very big mileages under heavy service conditions. The Herbert Freed Co., Ltd.. has lately produced a special improvement intended for use with Forodo, which greatly assists in keeping the lining cool when in use. It consists, broadly speaking, of a corrugated metal sheet, which is placed between the Ferodo lining and the brake block proper, avid greatly assists in dispersing by radiation the heat generated during application of the brake.

Fletcher, Russell and Co., Ltd. Head Office and Works: Warrington, Lanes.

The great improvement made of late years in high-speed steels has led to the introduction of many appliances which are specially intended for the treating and working of such material. A satisfactory hardening and annealing furnace is essential if the best work is to be obtained from high-speed

steels. The furnace illustrated herewith is a representative type of such an appliance. It is manufactured by Fletcher, Iluesell and Co., Ltd.

It can be geared to horsed cabs, sledges, and so forth, as well as, of course, to ordinary motordriven vehicles. This taximeter can be suited to all foreign coinage and distance data. The British Motor Cab Co., Ltd., has fitted, in all, 1500 of its cabs with Halda taximeters.

Harvey, Frost and Co., Ltd.

London Office : 39 and 41, Great Eastern Street, E.C.

We need hardly say at this stage that Harvey, Frost and Co., Ltd., occupies a prominent position in everything pertaining to tire repairs. It is a hard fact that one of the greatest expenses connected with the running of commercialmotor vehicles is that of tires. A really bad cut, during the early days of a tire's life, will frequently lead to early total destruction, if it he not seen to at an early stage. The HY. Co. supplies all kinds of vulcanizing plants, both large and small. It will repay many users of light vans, motorcabs or parcelears to put down a small H.F. vulcanizer. Many a tire can be invested with further mileage capacity if repairs are tackled promptly.

Hollings and Guest (1908), Ltd.

Head Office and Works : Thimble Mill Lane, Birmingham.

Of particular interest to our readers, so far as the manufactures of this company are concerned, are the special hydraulic tire and screw presses. These appliances are constantly being supplied to tire firms in England and Overseas. Many of the well-known tire companies employ from six to twelve of these presses. These are designed to deal with a. great number cf band tires. Overseas readers, however, will be specially interested in the smaller screw press, which is worked by hand, and which is intended for use where only one or two vehicles are employed. Providing always that the steel-tire band has not been rusted on the wheel for years, this press is powerful enough to remove it, and also to replace a new one without trouble. In case, however, of any band being almost irremovably rusted on, it can be removed by sawing and breaking. A new tire can then be put on, with the aid of the Hollings and Guest screw press, which is capable of giving a total squeeze of 40 tons.

Many motor manufacturers recommend the use of Price's oils.

Hans Renold, Ltd.

Head Office and Works : Progress Works, Brook Street, Manchester.

The chains made by this company require no urgent recomtremdation from WI. Their application to motor-driven vehicles is already considerable. Overseas readers, however, may not be aware that this maker supplies chains for many other purposes than that of final-drive transmission. Amongst these other applications may be cited chains for transmitting power in the workshop, for auxiliary motors, lathes, gearboxes and other machines and accessories. It may be stated broadly that, wherever belts are employed for power transmission, Hans Renold, Ltd., is equipped to supply a scheme and quotation for a specially-designed chain drive, which would do the required work.

Head Office and Works : 24 and 24a, Caledonia Street, King's Cross, London, N.

A rapidly-increasing number of motor vehicles is now being equipped with these radiators. It would be difficult to imagine a more-efficient system of tube cooling than that adopted by the Spiral Tube and Components Ce. It is particularly important, where machines are to operate in tropical climes, that the cooling system should be extremely efficient. The success which is attending the use of spiral tubes for vehicles intended for use under a hot sun, is ample proof that this component is proving satisfactory in service. The tube made by this concern presents many advantages over the ordinary type: it is both light and strong, and the minimum of soldering is needed in the jointing of the corrugated ribbon, which is helically wound on the tnise. The company has had groat experience in radiator construction, and the plaiit installed is capable of turning out a large number of these components.

Tubes, *Ltd.

Head Office and Works : Birmingham.

The increasing demand for efficiency in the construction and design of commercial motors has led several firms to give 'great attention to the materials and construction of various (component parts, on which the life of chassis may be said ;materially to depend. A prominent British factory which (has specialized in this particular-clase of work is Tubes, Ltd. ,It need hardly be said that expert opinion on back-axle (sleeves, torque tubes, and high-grade nickel-steel components, !etc., may readily be obtained from this company. Nothing 1,could he more conducive to extravagance in running than the trepeated failures of, say, a torque tube on a commercial vehicle, which may be, at the time, operating at a distance of several hundred miles from the nearest depot. It is only by paying strict attention to the materials from which these parts are made, that such a disastrous possibility can be obviated.

United Motor Industries, Ltd.

London Office : 45-6, Roland Street, W. It is questionable whether this company is not better known as the D.W.F.

C. A. Vandervell and Co.

Office and Works : Warple Way, Acton Vale, London, W. •

The C.A.V., dynamo-lighting system differs from all others in many essential features, one of which is the fact that a magnetic cut-out is not needed. By an ingenious use of the magnetic actions and reactions which occur between the armature and the field magnets, the output is kept constant at all speeds of the engine. It is a well-known fact that if a dynamo be run as a motor, and supplied with current from an accumulator, the amount of current taken will be proportionate to the load. In the case of a machine which is driven through chain or gearing by an engine, it will naturally= try to drive the engine, and the current will be excessive. In the C.A.V. dynamo a simple freewheel is interposed between the pulley sad the armature spindle, so that, when the engine is stopped, or is run too slowly for the dynamo to charge the accumulators, the armature may still revolve quite freely, thus overrunning the driving pulley. Owing to the design of this machine, a very small current is taken from the battery, because it is impossible to put any load upon the dynamo shaft while it is running az a motor. In service this system is meeting with a considerable amount of success. A large number of sets is in use on industrial vehicles.

C. C. Wakefield and Co.

London Office : 27, Cannon Street, E.C.

It is by now, we think, universally known, at any rate to users of motor vehicles, that a proper system of lubrication, together with suitable lubricants, must be employed if anything like the desired efficiency is to be obtained from motordriven vehicles in constant service. There are one or two firms who have made the question of lubrication and lubrirants a special study. The demand which is experienced for the services and manufactures of these firms is sufficient evidence that the departure has been fully justified.
