"The arrangement according-to the invention is not-solely applicable to projectiles with studs and to a cannon whose firing charge is introduced through the breech. it may further be utilized when the projectile iscprovided with stabilizing wings or when it carries its own firing charge. The projectile may even he of the'wing type and carry its ownfiring charge.
The appended drawings show byway of example an embodiment of the invention, a
modification 'of the form 'otthe cock, and a.
modified form ot-construction corresponding to the use of projectiles carrying their own firing charge. K
Fig. 1 is a'lengthwise section of a cannon constructed according to the in'vention.-
' 21s a transverse section oi the cock.

Fig. .6 is a horizontal view of the cock sho wn in Fig. 5, showing the form otthe orifices in said disks. u
Figs. 7 and 8 showa modified embodi ment of the invention in the case in which the projectile carries itsown firing charge; Fig.1.showsthecannon 1 which is divided into two partsby the partition 2, pierced with an orificeor tuyere in which'is engaged theprojection'a secured to the bottom otihe projectile 3. A-conduit 5 formed in the body of'thepartitiOn-Q.and opening into the wall of the tuyere, serves 'to connect this latter with a discharge tube 6 disposed along the cannon, through the medium of a cock '7 whose plug ii is rotatable in a cylindrical body or chamber 9 so as to close or'open tlie orifice of the tube 6.
axis which extends to the extcriorn'iay be actuated by meansot a knob, a crank or in any other manner, and that a dial concentric with the axis will allow oit indicating the positions to be given tothe cock plug in order to obtain thejdesired velocities. In the case above considered in which one fires at a constant angle and at a variable initial velocity, the dial of the cock may he graduated in firing distances. But it has also been stated above that it maybe advantagcousto regulate the degree of opening of the cock in proportion to, the angle of aiming for elevation;. a form of realization of this latter means for controlling thecock plug is shown, in Figs. 2 to 1-. p
This form of realization is given solely by way ot-example, and any other device providing for the connection between the said cock and the means for aiming for elevation while permitting the recoil ot the cannon may .be employed instead of the one'herein described. Such devices are in current use for varying the length of the recoil in proportion to the firing angle,'=lt'or apparatus in which the brake body is subject to recoil, "for example.
To the shaft 10 is keyeda bevel pinion 1-1 which is actuated by a set of pinions contained in a casing 12 se cured to thefmain body of the cock. The end pinion 13 is slidable'on'a rod 14: mounted on an arm 15 which is secured to the non-rolling part otthe pivoting aggregate. In the rod 14 is a longitudinal slot .in which is slidab'le astud carried by the pinion 13, thus obliging this latter to rotate with the rod 14:. i The latter carrie'sat thetront end an actuating pinion 23 t) in gear arrangement with a lateral toothedp ortion 24 ot the sector for aimin'gtor'eleva'tion 16. The arm 16 carries at the end the elevation mechanism comprising an operating crank 17 which actuates by bevel pinions and worm gearing the outer toothed portion'ot the-sector 16.
The values of the elevation are read 'upon the outer face of the sector 16 opposite a pointer25 mounted .on the arm 15. T 0 cor rect'the error due to an inclination of the carriageto the frontor'reanihe sector 16 is not fixed with ireterence'to the small pivot ing carriage 20. A mechanism analogous to the elevation mechanism, but mounted on the small carriage 20, allowsot-turning together as a whole the pivoting aggregate and the said sector, by acting upon the knob 21 which actuatesby bevel ,p inions and worm gearing an inner toothed portion formed on thelower part otthesector 16. A spirit level 22.n1ounted on the sector 16 serves to checkthe proper inclination of the latter.
The sector 16 is graduated in-such manner that the figure which is observed adjacent 'onrtheifiri'n g and the init a onds tofthis positio tothe' sector I16:
