WALTHER AKEMANN, OF ESSE'N, GERMANY, ASSIGNOR TO FRIED. ERUPP AE'EIEN- GESELIl-SGEAFT, F ESSEN-ON-TI-IE-RUHR, GERMANY.

CONNING TURRE'I.

Application filed January 3, 1921. Serial No. 434,633.

I (GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, .41 STAT. In, 1313.)

To all whom it may concern:

Be it known that I, WALTHER AKEMANN, residing at Essen, Germany, a citizen of the German Re ublic, have invented a certain new and useful Improvement in (Jouning Turrets (for which I have filed application in Germany, filed July 8th, 1916), of which the following is a specification.

This invention relates to a fixed conning 10 turret for men'of-war, having a cupola adapted to rotate about a vertical axis and supporting a telescope sight for its part ca pable of being stabilized by means of a gyroscope, and positively connected to a transmitter mounted within the turret and appertaining to an apparatus serving for laterally training the guns at long distance. The invention will be further described with reference to the accompanying drawing which illustrate one embodiment of the subject matter of the invention by way of example and in which a conning turret of a man-of-war is shown in a vertical section.

Referring to this drawing A denotes the turret which is rigidly mounted on the ship and is provided with a series of sight openings a and within the cover a of which a cupola A is disposed to rotate about a vertical axis. A bracket a extending into the interior of the cupola and fixed to the side wall "thereof carries a telescope sight a capable of being stabilized by means of a gyroscope (not shown). In addition 5 there is arranged in the side wall of the eupola, and in front of the object lens of the telescope sight a, a narrow observation opening a through which the object to be fired at may be observed by means of the telescope sight a A toothed wheel B having a hand wheel 12 pivoted to the cupola A and cooperating with an internally toothed wheel a, for its part rigidly fixed to the cover a of the turret serves to rotate the cupola A A seat a is arranged at the inner wall of the cupola A facing the eyepiece of the telescope sight, for the man appointed to observe the object; said seat being so located that the man may observe the object and at the same time rotate the hand wheel 6 The cupola A is furthermore provided with a part a extending into the turret and supporting a toothed-wheel a. A toothed wheel 0 meshes with the wheel a, the said toothed wheel 0 being mounted on the adjustable part G of the transmitter of an apparatus for laterally training the guns at longdistance, while the stationary part C of Said transmitter is fixed to a side wall of the turret. From the stationary partC of the transmitter a series of electric lines 0 run to the appropriate receivers (not shown) disposed at the gun emplac'ements, of the long-distance training apparatus. This apparatus is so constructed that every turn of the cupola A will be followed by a rotation, perfectly true in angle, of the adjustable parts of the respective receiver.

In the use of the described conning turret for laterally training the guns located at the receiver stations, and this while the ship is rolling, the gyroscope (not shown) is first of all set in motion and the telescope sight (L5 focused horizontally. Hereupon, the observer, seated as said at a sets the hand wheel Z2 in rotation, while at the same time observing the object by means of the telescope sight a. As the hand wheel I) rotates, the toothed wheel B rigidly connected to the hand wheel rolls over the stationary toothed wheel a so that the cupola A is set in rotation about its vertical central axis. The rotation of the hand wheel 12 and therewith the rotation of the cupola A is continued until the telescope sight a, which retains its horizontal position owing to the effect of the gyroscopic rotation, has been focused laterally upon the object to be fired at. In this rotation of the cupola A participates by intervention of the toothed gear (L10 c the adjustable part C of the transmitter C C of the long distance train- 'ing apparatus for the guns to be pointed,

and this in such wise that the angular lateral displacement imparted to the cupola A will be transmitted true in angle, upon the receivers located at the gun emplacements. 4 g

The hereinbefore described conning turret is distinguished by the parts required for lateral training at long distance being so constructed and arranged that, on the one hand, the lateral training at long distance of the guns in question can e effected with utmost accuracy even while the lit! ship is rolling, Whereas, on the other hand, the probability of shells penetrating the sight opening provided for observing the object that may be located'in any direction whatsoever, is reduced to a minimum.

Claims.

1. An arrangement of the class described comprising a conning turret, a rotatable cupola mounted upon said turret, a sighting device and stabilizing means therefor supportedin' said cupola, means for rotating said cupola and rotating therewith, and means initiated by the rotation of said cupola for laterally training guns.

2. An arrangement of the class described comprising a conning turret, a rotatable cupola mounted upon said turret, a stabilized sighting device supported within said cupola for rotation therewith, means for rotating said cupola'with respect to said turret and an electric long distance control device operatively connected to said cupola and operated upon its rotation for, effecting a lateral training of guns.

3 A conning turretfor men-of-War com prising in combination a cupola, means securing said cupola to said turret to permitsaid cupola to rotate about a vertical axis and relatively to said turret, a stabilized mechanism for rotating said cupola relatively to said turret, a transmitter secured to said turret and forming a part of an electrical distance gun training mechanism and mechanical connection between said transmitter and cupola whereby rotation of said cupola will effect a rotation of said transmitter.
