GUN WITH RAILWAY GUN-CARRIAGE.

. Specicaton of Letters Patent.

Patented Nov. 30, 1920.

Application led September 8, 1920. Serial No. 408,980.

T0 all who/m t 'may conce/rn:

Be it known that I, RUDOLF LORENZ, residing at Essen, Germany, a citizen of the German Republic, have invented certain new and useful Improvements in Guns with Railway Gun-Carriages, of which the following is a specification.

This invention relates to `guns with railway gun carriages and has reference' to the special arrangement of the rear bogie of the railway carriage.

The invention will be described with reference to the accompanying drawings in which the invention is diagrammatically illustrated.

Figure l is a side elevation of the gun in the transport position,

Fig. 2 is a side elevation or' the gun in the firing position and Fig. 3 is a transverse section on a larger scale through the bogie pinbearing of the rear bogie.

rEhe railway gun carriage `has a frame B, which is supported at 01 and Z1 on two D. The gun barrel E is guided in the cradle i?, which is pivotally mounted in the frame B by means of horizontal trunnions f1. Between the cradle F and the frame B there is interposed an elevating gear not shown in the drawing.

rEhe pivot pin ot' the rear bogie D, which is constructed in the form of a knuckle pin J (see Fig. 3) bears in a pan di. This knuckle pinis fixed to the frame B by means of ribs g1 of a slideway plate G connected to the frame. The bogie D is secured relatively to the frame B by means of a bolt H (see Fig. 3) which can Vbe inserted in bolt holes in the parts B, Gr and .l J1. in the frame B and the slideway G are formed bolt holes which correspond to the positions I and Il of the bogie D (see Figs. l and 2) When the gun is in the transport position, the rear bogie D occupies the position I (see Fig. l) in which it is brought so near to the front bogie C that on curves the gun is not swung too far sidevise, and therefore the contour of the railway line can be ei'iiciently utilized. The distances i and *1 between the vertical axes oi: rotation of the bogies C, D, from the center of gravity S of the gun as a whole are so calculated that the load is uniformly distributed on the several axles of the bogies.

As shown in the drawing the center of gravity S lies nearer to the front bogie C, which is therefore more heavily loaded and therefore has one axle more than the rear bogie` This corresponds to the actual conditions and is the result of the fact that an equalizer (not shown in the drawing) is to be mounted on the front part Oi' the frame B, which compensates the front weight of the parts of the gun, which oscillate about the trunnions.

T'Vhen the gun is to be transferred to the ring position, the bogie D is pushed to the rear into position II, (see Fig. 2) and secured in this position by the bolt Bl. vVith the rear bogie in this position the distance between the bogie D and the trunnions fl is so great that the gun barrel E when iii-ed at an elevation and recoiling does not st1 e against the bogie (see the position of the barrel E shown in dot and dash lines in Fior. 2).

laims.

l. A railway gun and carriage therefor which comprises a frame, a gun supporte@ on the frame, two bogies, means pivotally supporting said frame at each end thereof upon one of the bogies and means whereby this pivotal support at one end of the traine may be varied.

2. A. railway gun and carriage therefor which comprises two 1oogies., a frame supporting the gun, pivotal connections between each end of the frame and the bogiA i and means whereby one of these pivotal connections can be adjusted longitudinally oif the frame.

3. A railway gun and carriage therefor which comprises bog-ies, a frame supporting the gun, means pivotally supporting' each end of the frame upon the bogies, one of said pivotal connections comprising a knuckle pin, a bearing therefor, said knuckle pin being slidably mounted with respect to said frame and means for securing said knuckle pin in its adjusted positions, substantially as described` The foregoing specification sil ned at Essen, Germany, this 20th day of Miay, 1920.
