UNITED STATES PATENT I OFFICE.
GILBERT ALFRED CASSAGNES, OF PARIS, FRANCE.
ORDNANCE.
FPECIFIGATION forming part of Letters Patent No. 279,636, dated June 19, 1883. Application filed March in. 188.1. (No model.) Patented in France February 12. I883.
To all whom it may concern.-
Be it. known that I, GILBERT ALFRED Cas- SAGNES, a citizen ot' France, residing in the city of Paris, in the French Republic, haveinvented a new and useful Improvement in Ordnance, (for which I have obtained a patentin France, bearing date February 12, 1883, for fitteen years,) of which the following is a specitication.
Ordnance as at present constructed are usually strengthened internally with cylindrical metal hoops heated and shrunk in position. These hoops of iron or steel otier considerable resistance in a transverse sense, but add noth ing to the longitudinal resistance of the arm.
The objectof this invention is to so form and apply the hoops that they are compelled'to participate in the longitudinal resistance. With this view, and as represented by the accompanying drawing, which is alongitudinal section embodying my invention, 1 give a truncated form to the internal and external surfaces of the hoops when several layers are superposed, the inclination of the superposed cones being placed inversely, care being taken to cross or alternate the joints. Thus the inner or first layer of cones, formed of the hoops A Af A A A, have their bases facing toward the breech of the gun, while the exterior of these same conical hoops and the interior of the second or outer layer of cones,B B B B 'B, have their bases turned to the mouth of the gun-that is to say, the inner summit of the conical hoops of the first layer, A A A A" A, faces the muzzle, while the external summit of each of these same cones, aswell as the internal summit of each of the cones B B B B B of the second layer, is placed toward the breech.
It should be mentioned that in the drawing the truncation of the conical hoops is exagger ated, so as to render them more visible. The result of this arrangement is thatany displacement of the metal tube which would have a tendency to unbreeeh the rear of the cannon would have the effect of wedging the hoop immediately above a, which would cause the longitudinal pressure to bear on the hoop B of the second layer. This latter would transmit the pressure to the hoop A, which would coinlnnnicate it to B, which again transmits it to B, and so on successively to the trunnionhoop B. The rear ends of the hoops A A A", &c., bear against shoulders that are formed on the body of the gun. It follows that, the whole being composed of detached parts, this novel mode of hooping constitutes an ensemble eapable of resisting the breakage as well as the unbreeching of the cannon.
Having thus described my invention, 1' claim- The cannon constructed and combined with truncated metal hoops in several concentric layers, the inclination of the concs being reverse( 1 each layer of cones, and each outer layer breakiugjoints with the inner layer, the hoops of the innermost layer bearing with their rear ends against shouldeis on the body of the cannon, substantially as described.
GILBERT ALFRED CASSAGNES.
