Definitions

  • This invention relates to a device em- ⁇ for the dischargeof the Aliquid which is submittedto the action of springs, the said stroke of .the valve and the tension of the device controlling the ⁇ regulation of .the
  • the said inclined plane will occupy for each aiming angle a determined position which it preserves throughout the entire period of the recoil and which 4depends solely upon the orientation of the cam.
  • the said cam is preferably set in rotation starting from a given aiming angle, and the position thereof will be subsequently modified for all greater inclination which is given to the piece.
  • Figs. 1 and l*L are side elevations of the piece.
  • Fig. 2 is a vertical section on the line A--A, Fig. 1.
  • '0'. 3 is a partial vertical F1 une is-B, Fig. 1.
  • section on the Fig. 4 is ahorizontal section on the line C-C, Fig. 3.
  • a brake body 7 is secured to the piece 1 for instance by a hoop 8, and the piston rod vof the brake 9 is secured to the front part of the cradle 3.
  • Tothe main body of the brake is secured a receptacle 10, containing-.in a known manner the valve employed for theldischarge of the liquid whichis subject tothe ⁇ tension of a weak spring, and also the stopl piece of the said valve which is separated from the said yregulating inclined plane by a stronger elastic device.
  • the said cam is mounted upon two trunnions 14 and 15 which are maintained-in the bearings 16 and 17 secured to the cradle 3.
  • the said device is operated as follows: At the same time as the piece is aimed in elevation, the quadrant 22 controls the position of the cam 13 by means of the gear wheels 21, 19 and 18. By reason of the spiral form of the said cam, the roller 12 will be more or less raised according to the angle. and in consequence the inclined plane will come into action to a greater or less degree within the casing 10 in order to gradually counteract the lifting of the valve by the opposition ofthe resistance due to the powerful elastic device. It is preferable that the quadrant 22 should come into action only after a given value of the aiming angle is reached. To this effect, the said quadrant comprises a smooth portion having a radius of greater value than that of the bottom of the teeth. In these conditions, during the entire passage of the smooth part of the said quadrant be'liore the pinion 21, the latter Will be immobilized and the device cannot be put out oit order.
  • the cam 13 may be given any suitable profile in order to obtain a constant reaction during the entire period o'l' the recoil in a very exact manner.
  • a regulating device for vthe flow of liquid comprising 'a regulating element for the HOW, a revoluble cam mounted on the cradle of the piece of artillery and acting upon the said regulating element, the said cam having the same length as the recoil stroke of the cannon, a piston fixed to said cradle, a hydraulic cylinder for the piston movable -vvith the cannon, said cam being rotatable independently of said cylinder, and transmission means for effecting the orientation of the said cam in cooperation With the aiming of the cannon for elevation.
  • a regulating device for the flow of liquid comprising a regulating element for the flow, a roller disposed upon the said element, a revoluble cam adapted to be mounted upon the carriage of the piece of artillery and having the same length as the recoil stroke of the cannon and a cross-section in the form of av spiral, the said roller being caused to roll during the recoil along a generatriX of the said cam, and transmission means for effecting the orientation Vof the said cam in cooperation with the aiming of the cannon for elevation.
  • a regulating device for the flow of liquid comprising a regulating element for the HOW, a revoluble cam mounted on the cradle of the piece of artillery and acting upon the said regulating element, the said cam having the same length as the recoil stroke of the cannon, a piston liXed to said cradle, a hydraulic cylinder for the piston movable with the cannon, said cam being rotatable independently of said cylinder, a bevel gear mounted on the aXle of the said cam, a stationary toothed quadrant secured to the carriage of the piece of artillery, and gear Wheels connecting the said quadrant with the said bevel gear.
  • a regulating device for the flow of liquid comprising a regulating element for the flow, a revoluble cam adapted to be mounted on the cradle of the piece of artil- Alery and acting upon the said vregulating element, the said cam having the same length as the recoil stroke of the cannon, a bevel gear mounted on the axle of the said cam, a toothed quadrant secured to the carriage of the piece of artillery, and gear Wheels connecting the said quadrant With the said bevel gear, the said quadrant having a nontoothed portion whereby the same shall be prevented from acting except after a stated value of the aiming angle is reached, the non-toothed portion having a greater radius than that of the bottom of the teeth.
