Specification of Letters Patent.

Application filed September 4, 1920. Serial No. 408,324.

This invention relates to shell bogies carried by the usual rotary trunk through which ammunition is lifted in cages to the guns and is particularly intended for use in the supply of ammunition to the middle gun of a three gun turret.

According to the invention the bogie has a shell tray which is supported by the bogie so as to be capable of movement about a vertical axis to bring it from a receiving position in which it is approximately tangential to the trunk into a discharging position in which it is parallel or approximately so to the longitudinal "axis of the turret and in line with the tray or compartment of the lifting or gun loading cage.

A power operated rammer may be provided for transferring the 'shells nose or baseforemost from the bogie tray to the cage and the press or other motor for the ramrner may be carried by the trunk while the rammer itself may becarried by the bogie tray or a part moving therewith, means being provided whereby a connection is automatically established between the motor and the rammer as the bogie tray assumes its correct discharging position.

In order that the said invention may be clearly understood and readily carried into effect the same will be more fully described with reference to the accompanying drawings, in which Figures 1 and 2 are respectively a vertical section and a plan of a bogie provided with a shell tray constructed in accordance with the invention, the parts being shown in the position they accupy when a shell is on the tray ready to be rammed on to the tray of the lifting cage.

Fig. 3 is a view similar to Fig. 1 but showing the parts in the position they occupy when the shell has been rammed on to the tray of the lifting cage, and

Figs. 4 and 5 are sections taken respectively on the lines l, 4 and 5, 5 of Fig. 1 and drawn to a larger scale.

A is the shell bogie which is of substantially usual construction, A is part of the trunk, and B is the shell tray rotatably mounted on'the bogies so as to be capable of moving about a vertical axis, the said tray in the example shown being moved by worm gearing operated by a handle B. The tray is shown by full lines in Fig. 2 in the discharging position in which it is parallel to the longitudinal axis of the turret and in line with the tray B of the lifting cage and. is shown by chain lines in the receiving position in which it is approximately tangential to the trunk. A tray B is attached to the trunk and serves as a bridge between the tray B and the tray B is the rammer operating to transfer the shells nose foremost from the tray B to the tray of the lifting cage, this rammer being in the example shown of the chain type passing around a sprocket wheel C carried by the rear end of a rod C slidably mounted in the tray B; the motor for operating the rod C is in the form of a press D carried by the trunk, the rod D of this press being connected to the rod C in such a manner as to permit the latter to become disconnected from the rod D by movement of the tray B from its discharging toward its receiving position and also as to permit the two rods to become connected by the movement of the tray B into its discharging position; for this purpose the end of the rod D has for example a tongue D of T shaped section (see Fig. 1) engaging in a corresponding groove in the end of the rod C What we claim and desire to secure by Letters'Patent of the United States is 1. In ammunition hoisting apparatus for ordnance, the combination with the ammunition trunk, the shell bogie on said trunk and the shell receptacle of the lifting cage in said trunk, of a shell receptacle on said bogie and means for pivoting the last-mentioned receptacle for swinging about a vertical axis to bring it into line with the firstmentioned receptacle.

2. In ammunition hoisting apparatus for ordnance, the comblnation with the ammunition trunk, the shell bogie on said trunk and the shell receptacle of the lifting cage in said trunk, of a shell receptacle on said bogie andmeans for pivoting the last mentioned receptacle for swinging about a vertical axis to bring it from a receiving position in which it is approximately tangential to the nition trunk, the shell bogie on said trunk and the shell receptacle of the lifting cage in said trunk, of a shell receptacle on said bogie, means for pivoting the last mentioned receptacle for swinging about a vertical axis to bring it from a receiving position in which it is approximately tangential to the ammunition trunk into a discharging position in which it is approximately paral- 191 to the longitudinal axis of the gun turret and in line with the-shell receptacle of the lifting cage, a ramming element on the bogie receptacle, a motor on the ammunition trunk and means whereby a connection is automatically established between said ramming element and said motor as the bogie rece tacle assumes its dischar in nosition.

4. In ammunition hoisting apparatus for ordnance, the combination with the ammunition trunk, the shell bogie on said trunk and the shell receptacle of the lifting cage in said trunk, of a shell receptacle on said bogie, means for pivoting the last mentioned receptacle for winging about a ver- 7 tical axis to bring'it from a receiving position in which it is approximately tangential to the ammunition trunk into a discharging position in which it is approximately parallel to the longitudinal axis of the gun turret and in line with the shell receptacle of the lifting cage, a chain rammer on thebogie receptacle, a rod for operating said rammer also carried by this receptacle, a press, including a cylinder and a rod, mounted on the ammunition trunk and means whereby a connection is automatically established between said rods as the bogie receptacle assumes its discharging position.

5. In ammunition hoisting apparatus for ordnance the combination with the ammunition trunk, the shell bogie on said trunk and the shell tray of the lifting cage in said trunk of a shell tray on said bogie, means for pivoting the last mentioned tray. for swinging about a vertical axis to bring it from a receiving position in which it is tan gential to the ammunition trunk into a hoisting position in which it is approxi mately parallel to the longitudinal axis of the gun turret and in line with the shell. tray of the lifting cage, a ramming element on the bogie tray, a motor on the ammunition trunk and means whereby a connection i automatically established between said" ramming element and said motor as the bogie tray assumes its discharging position.

6. In ammunition hoisting apparatus for ordnance, the combination with the ammunition trunk, the shell bogie on said trunk and the shell tray of the lifting cage in said trunk. of a shell tray on said bogie, means for pivoting the last mentioned tray for swinging about a vertical axis to bring it from a receiving position in which it is 'a proximately tangential to the ammunition trunk into a. discharging position. in which it is approximately parallel to the longitudinal axis of the gun turret and in line with the shell tray of the lifting cage, a chain rammer on the bogie tray, a rod for operating said rammer also carried by this tray,

a press, including a cylinder and a rod,
