JULY 5, 1913. of some interest to mention that this firm have l.een experimenting with a special dope for use on untreated fabrics, tightening and giving the latter a smooth waterproof coating. They have been quite satisfied with the results of these experiments, and have, there fore, placed the dope on the market. Hi THERE is no doubt that welded and pressed steel work, when done by those who know how, lends itself very well to aeroplane work, and it is not surprising therefore to know that a by no means unimportant branch of the business of Messrs. Rubery Owen and Co., of Darlaston, South Staffs, who are known the world over as specialists in this branch of metal work, is that devoted to fittings for aeroplanes and aircraft. Besides being strong and light, the [/OCHT use of pressed or welded steel will often greatly simplify construction. As an example of the work executed by this firm, we show herewith two pressed and welded steel engine mountings, such as would be employed for use with Gnome engines. It only remains for us to add that Messrs. Rubery Owen undertake to execute almost any work of this kind that may be submitted to them. THERE are few aeroplane records which have been made since that historic Sunday, July 25th, 1909, when M. Bleriot flew across the Channel, in which the Chauviere Integral Propellers have not played a part, and ?o they have steadily built up a reputation placing them with the best in the from rank. It is with some satisfaction therefore, that we learn that these propellers are no * being made in this country by British labour. Up to recently M. Chauviere visit the works wc re not in full operation. It will be remembered that the principal feature of the Chauviere lies in the shape of the blades, as illustrated by the accompanying diagram. The cutting edges are curved, the rear edges being straight, ihc ultimate (ffect of which is to allow a part of the air-pressure to be brought behind the axis of the propeller, r'.*., on the rear part of the blades, thereby avoiding deformation which tends to alter the pitch—a fault with many badly-designed propellers. The Integral propellers are built up of layers of picked best quality French walnut glued together with a special glue invented by M. Chauviere. Great precautions are taken to ensuie wood used being of exactly the same density in its entire length. When the propeller is properly formed, a great deal of attention is given to the balancing of the same by means of another invention of M. Chauviere, a special form of balancing mechanism which registers the slightest defect. They have recently placed on the market a propeller with a variable pitch and metallic lioss, a system particulaily suitable for testing or experimenting. In 1908, they patented their metal-tipped propellers for hydro aeroplane work, and now that the latter type of aircraft is well established, the true value of these propellers has a'ready made itself apparent. ALT HOUGH there are several firms supplying the wants of aero- plane constructors so far as wood as a raw material is corcemed, there are only a very few who make a speciality of not only ob'aining the wood itself, but also undertaking to turn out the finished article —such as ribs, skids, struts, &c.—to the designer's own specifica tions. Messrs, R. Cattle and Co., of 27, Wybert Street, Stanhope Street, London, N.W., a firm of wood workers of some 40 years' sanding, and well known in the picture-frame world for their utrned-from-the solid oval frames, is one of the very few exceptions in this connection. They have only just moved into the above premises, which are much larger thun their old works, the ground floor itself covering 16 ooosq. ft. They h-vca very fine plant, most of the machinery having been designed and constructed by them selves. As regards the work melf, we were particularly struck with the excellent finish of that which we saw on the occasion of our vi^it to the factory >ome few weeks back. This is not surprising, however, when it is stated that nearly every employee has been with Mr. Cattle almost from the start, and each man has his own particular class of work, and that only, so tach man is an expert at his own job. A point Mr. Cattle wishes to emphasize is that all work it carried out in confidence. AEROI'I.ANF. designers are now giving much more attention to the comfort of the pilot and passenger by providing better proiec ion from the elements. Important as this is, it more often than not has been represented in this country solely by his office at 307, Euston Road, London, N.W., but lately some temporary workshops have been secured at Kentish Town where Integral propellers will be made and in the near future it is intended to establish a large factory at some convenient place. In the accompanying illustrations are seen a couple of views in the new workshops, but it should be pointed out that at the time of our has the drawback of obscuring the view, in which case the only remedy is to fit windows. Glass is by no means suitable for this purpose, and cellu'oid, though light, is extremely dangerous on account of its inflammability. The Cellon Co., of 49, Queen Victoria Street, Londm, E.C., well known to our readers for their dope for fabrics, manufacture a transparent material that has all the advantages of ordinary celluloid without the dinger referred to 745
