SEPTEMBER 6, 1,917. of inability to obtain magnetos. Here, one would think, are magnetos sufficient in quantity to supply the aero engines of the world, and heaps to spare, yet such is the demand, that almost to the exclusion of all else, " Blic " machines for aircraft are the one and immediate article of manufacture. For all that the company are not neglecting the many other- calls for magnetos, as, for instance, for large stationery gas- engines. One of the models for this purpose is shown in the illustration ; it is for large 8-cylinder engines, and weighs 63 lbs. Also the company have an eye on after-the-war necessities, and although the fact that they are engaged at the moment almost solely on aircraft requirements, does not mean that they are incapable oi taking other work, they have laid down the necessary tools and equipment for a number of other types of machine, which will place them in a position, on the cessation of hostilities, to furnish at short notice, any type of magneto that may be required. Mr. Arthur Bennett is^in charge as of old, and it is greatly due to his untiring energy and organising ability that much of the immediate success of the business, and the speed at which it is possible to fulfil orders lies. A DIE HEAD, manufactured by the Murchey Co., of America, andjstocked by their sole agents for this country, the Coats Machine Tool Co., Ltd., of Thanet House, Strand, is specially adaptable for use on the production of aeroplane parts. The die^head was illustrated in our advertisement pages a short time ago, but is Worthy of special notice by reason of the many advantages claimed by the makers for this die head over other types for the purposes under notice. It will thread Nos. 2 and 4 British Association right and left hand. At the same time it has a capacity of £ in. WhitWorth, 6 mm., or -No. O.B.A., so that chasers can be supplied to thread up to all these diameters. To obtain continued accuracy, the bodies are made of hardened tool steel, carefully ground and lapped ; the chasers being firmly held in hardened slots and packed by steel bearings, Which give direct support Where the strain of cutting is greatest. Head known as Type A. can be supplied in any size up to a total capacity of 12 in., and full particulars will be readily furnished by *he Coats Machine Tool Co.. Ltd., on application. ONE of the most useful little tools lately placed on the market s the " Duco " combination valve spring lifter, chain puller, and patch press, which, although designed for motorists, will be found useful in and around an aeroplane Workshop. Used in connection With the removal of valves, it gives a direct lift, thereby avoiding the danger of bent valves, and in addition, leaving both hands free for the work in hand. The lifter is provided with two plates that easily slip into position when it becomes necessary to use the tool for pressing a repair patch on to the inner tube. As a chain puller, a glance at the illustration will show the method of using in one of these minor operations that fall to the lot of those who have to do With motors, and one Where one always feels the want of half-a-dozen hands. With this device, the two ends of the chain can be pulled together, and held in position whilst the pin is inserted and fixed securely. A post card to Messrs. Brown Brothers Will bring full particulars of this handy tool, the moderate prices of which in the two sizes for cycles or cars is a matter of 4s. 6d. for the former, complete with plates, and bs. for the latter without plates. As the name " Duco " implies, it is sold by Messrs. Brown Brothers, of Great Eastern Street. QUITE a strong little pin for use in aeroplane construction is being supplied by Adolphe Arbenz, of 35, Ludgate Hill, Birmingham. The pins are of the well-known semi-spherical brass-headed variety, With steel shanks, yet, members of a common family, they have a point of their own, in addition to the working one. The shank does not pass through or partly through the head, but is butted to the under part, and held strongly in position by a cone-shaped strengthener that is integral with the head and grasps the pin about half- way between the crown and the rim of the head, thus giving strength just where it is required to prevent that exasperating displacement of the head sideways when the pin is being driven into hard wood. NOT entirely new to the business, inasmuch as they were manufacturing aero parts to Government specification before the war, the Rotax Motor Accessories Co., Ltd., have now, owing to insistent demand, laid down additional plant suffi- ciently large as to be able to guarantee early and substantial deliveries of the aero parts of their manufacture. Their latest catalogue just to hand, contains a comprehensive list with illustrations of the various lines handled by the firm, with the further information that any article therein contained, but required in slightly different sizes, can be secured on appli- cation to them, stating requirements. The list contains all the usual articles associated with the small parts necessary to the building of aeroplanes, and will be sent free on applica- tion to Rotax Works, Victoria Road, Willesden, N.W.10. A RADIATOR which has been heavily damaged, often looks an impossible proposition from the repairer's point of view, but the experience of Messrs. Barimar is that it is very seldom if ever, that a radiator need be scrapped from this cause. BEFORE AND AFTER.—The photograph on the left shows a Curtiss radiator as received at the Barimar works, while on the right the same radiator "as good as new'' is se,en after treatment by the ; .• .. . - Barimar experts. One of our two photographs shows a radiator, off a Curtiss machine, which, to put it mildly, has been severely treated, or rather maltreated, yet the other photograph is of the identical radiator, after it had gone through a course of treatment at the Barimar hospital. So, however badly damaged a radiator may be, it will be worth while, especially at the present time when spare parts are so scarce, to send it along to Barimar, Ltd., 10, Poland Street, Oxford Street, W.
