floating gun-barrel support; links crossing each other and hinged at their end torfthe' carriage and to the floating support, a, weight I '20 guided in a vertical dii eetion and supported by links pivoted thereto and to the lower end i of the floating gun-barrel support, and asrecoil-brake connected to the upper cross-link g crossing each other and pivoted to the carriage-frarne by bolts f and h respectively and to the floating support by bolts e and t, a bal mice-weight is guided vertically on the carriage-frame and suspended omthe lower end of the floating gun-barrel support, and a. recoil-brake *rt-having its .piston -rod w eonneoted to thebolt e, substantially as specified.
