duction of engines of this type. Before proceeding to give a brief description of the various /types of engines made by this firm, a few historical notes may be of interest. The entry of Messrs. Brazil, Straker and Co., Ltd., into the field of aero engine manufacture dates back to the summer of 1915, when aero engine work was undertaken for the Air Department of the Admiralty. Ever since then the firm has been engaged upon work for this department and, later, for the Air Ministry, the work including the reconstructed Curtiss, and the " Hawk" and " Falcon " Rolls-Royce aero engines. Incidentally, it might be mentioned that, JULY 3, 1919 for the management of the Cosmos Engineering Co. realised the importance of not attempting to carry out experimental work in the production factory and, more than two years ago, an entirely separate experimental factory was formed which is organised and controlled by a separate experi mental staff. The experimental department of the Cosmos Engineering Co., Ltd., is now.one of the best-equipped in the country, being installed in new buildings, with a new machine shop, and with an excellent test house in which new features of design are thoroughly tested out before being finally adopted. THE COSMOS 450 H.P. "JUPITER" ENGINE.—Front and rear view. so far as we are aware, this is the only firm which has been entrusted with the manufacture of Rolls-Royce engines, apart, of course, from Messrs. Rolls-Royce themselves. Also, with the exception of the original experimental engine, Messrs. Brazil, Straker and Co., Ltd., have produced the whole output of the R.R. " Hawk " engine. At the close of 1918 the firm of Brazil, Straker and Co., Ltd., was reconstructed, and became the Cosmos Engineering Co., Ltd., and, as already mentioned, the firm has decided on a post-War programme concentrating on the production of radial air- cooled engines. Already during the War those responsible One part of the building is fitted up for the testing of separate cylinders, the power developed, the petrol and oil consumption and the temperature being taken and noted. When a single cylinder has in this manner been thoroughly tested out and has fulfilled the rigorous demands imposed by Mr. Fedden, technical director of the firm, a complete engine is erected and tested in another shop where such parts as were not incorporated in the test of separate cylinders are given a thorough try-out. When parts have been tested here, and any of them that proved unsatisfactory have been re-designed and tested, the complete engines are given long The Cosmos " Jupiter engine, 450 h.p., installed in a " Bristol " Badger.
