Description

IMPERIAL

PATENT OFFICE.

The element driving the detonator is the air, namely the draft generated by the flight and the rotation of the projectile around its own axis, which must turn helical wind fans on a wind vane and the latter itself if a small wind hood A is arranged around the upper part of the wind vane will. This wind hood A is made of tempered or iron cast iron and adapted to the cross section of the wind fan. Air escape holes ο are provided at the base of the hood so that the air flowing in through the small air passage holes χ at the top of the hood can find its way out again and cause a good draft in the wind hood. A sleeve B is arranged around the actual detonator and is firmly connected to the projectile. Likewise, the wind hood and sleeve are firmly connected to one another.

The wind impeller consists of the helical wind blades a, the axis b and the gear wheel c and is mounted in bearings d. A double gear ef , which runs in bearings h, is connected to the gear c on the main axis b. With this gear is again provided with a firing pin and helical spring comb wheel i in connection, which can only make one slowed rotation due to the gear transmission; by engaging a further or two further gearwheels, the rotation of the ignition impact wheel i can be slowed down significantly. The axis of the ignition impact wheel is denoted by I; the wheel i has a strong hub k and is pulled down by the helical spring m held by the pin η. A slide pin ρ is attached to the gear wheel i.

The Zündschlagrad i can be lifted over a rotatable drum g respectively. push up; this drum g rests in a floor and is fastened in the same by a fold. In this rotatable drum g there is provided a slide hole c ¹ calculated for the pin ρ of the ignition impact wheel i and precisely on the periphery of the revolution of the same. G to the rotatable drum, a riser brackets ■ {is attached to the sites of the deflecting device.

The firing pin ο stöfst in the Zündmasse which is on the r held by a bracket and powder filled Zündschlagröhre C. So that at event. If the detonator is unable to turn the main drive wheel with the wind vanes α , a small ratchet wheel d ^{l is} attached to the axis b , into which a locking bracket b ^r with a ratchet tooth can be pressed.

If the locking bar is switched on, the drum g can be turned around as desired by means of the adjusting pin \ without the cocked detonator being able to go off.

The operation and mode of operation of the detonator is now as follows:

The detonator is placed before screwing on, ie the hammer tube C with the hammer socket is carefully pushed sideways by first pushing back the hammer spring a little. Once this has been done, the striker I is pushed up with the spring until the pin ρ on the comb wheel i is above the drum g . A small turn of the bolt / from left to right then secures the pin on the slide drum. You now run through

turn the bolt, move the detonator from left to right until the pin ρ is close behind the small bead ν on the slide drum.

The spring m is tensioned and the comb wheel i is raised by the length of the sliding pin ρ on the comb wheel f . The main drive wheel is now fixed by the locking bracket b ¹ and the drum can then be turned around in its path as desired without running the risk of ignition.

The ignition device is therefore set to the explosion time for the furthest distance. You then screw the detonator onto the missile. Above the adjusting bracket, a scale is attached to the periphery of the jacket, e.g. B. io to ι km from Y ₂ to Y ₂ falling. When the command comes z. For example: "5 kilometers", you set the bracket to 5, the drum rotates and the detonator's expiry time is shortened from 10 to 5 km. The sliding pin ρ must therefore slide faster into the sliding hole c ^{1 of} the drum.

You now put the locking bracket b ^{1 off} again, and the storey is ready for loading.

The cocking can be done in the depot and the ignition is immediately set to the furthest distance; the rotation of the wind impeller is prevented by the locking device b ¹ ; in such a condition the finished story can be kept for a long time.

With the command "500 meters" the soldier puts the bracket of the adjusting device on, for example, 5 of the scale and on the command "done" the soldier pushes the locking device back, and the storey is ready for loading. The stroke of the striking mechanism can be increased by lengthening the comb wheel / and the sliding pin ρ . It is also possible to manufacture several detonators for the different types of gun, large and small, with short or long gear transmission, and by engaging one or more gear wheels the rotation of the impact wheel i can be reduced to a minimum, thus also a long flight time of the projectile use it for ignition. Furthermore, you can slow down the rotation and the mode of action of the detonator by 1. drilling the wind passage holes χ at the head of the wind hood A large or small and thus allowing the air to flow through strongly or weakly, or 2. making the mainspring m weak or strong in order to accelerate or slow down the striking mechanism through such. ·.
