DE330966C - Device for setting guns, searchlights and similar objects from an observation point, taking into account the parallactic deviation caused by the location of the guns - Google Patents

Description

In the facilities where several spatially separated objects, such as guns, searchlights, Telescopes or similar, turn pointed from one place to a certain point must, it is necessary to depend on the location of the items parallactic deviation to be taken into account in order to set up the individual precisely ίο items to ensure the specific destination. Facilities have already become known in which the correction ■ · - of the setting with consideration for the equatorial Deviation · happens. It has therefore been assumed that the distance of the observed point in relation to the distance of the gun from the observation point is not too big. In this case the parallactic deviation can be; after so calculate the following formulas:

B (Fig. I) denotes the measured distance of the target from the observation point, α the observation angle which the target line forms with the inclination line of the schematic throwers or telescopes, A ₁ , A ₂ , A _s the distances between the individual objects Observation point so is

ie ß =

tgy -
tg * =

E · sin α

E · cos α - A ₁

E · sin a.

E · cos α - ^ ₂

E · sin α

£ cos ci-A,

etc.

These known devices can be used in cases where the distance of the target of the gun is very large, do not use it. Geraide these cases, however, are the present large ranges of the guns the more frequent. You can use the Distance · of the individual guns from the observed point equal, so that then, according to Fig. 2, the equations for the parallactic deviations result:

2. sin O ₁ = - ~ sm α

A ₂ . sm Ct ₂ = - ~ sm a.

K ■ sm ag = - ~ sin α etc.

It follows that the ParaHaxe with the

■ The sine of the lateral angle grows linearly with it. the distance decreases.

While ', as mentioned above, use is made of the formulas ι in the known device, the invention now relates to a device which is based on the formulas given under 2. As a result, one and the same amount for the lateral direction is communicated to the individual guns from the observatory, and! the parallactic correction does not take effect until the individual guns are set in the direction indicated. The device can be designed in such a way that the correction device acts after a pointer adjusted by the observation point ^{when the cannon 1 is mounted;}

ao active setting of the gun comes into effect.

On the drawing is in Figs. 3 and 4 an Ausfühnungsformi of the invention for Case indicated that the adjustment of the guns by the operating crew itself takes place.

The aiming device α (telescope or the like) acts in a known manner on a transmitter system b , which transmits its setting corresponding to the movement of the target to the receiver systems C ₁ , C ₂ , C ₃ attached to the individual guns. On the

■ Pointers d _lt d ₂ , d _{z of} these receiver systems are then set with simultaneous adjustment of the guns counter- _{pointers e w} e ₂ , e ₃ . The movement required to set this counter-pointer is now corresponding according to the invention! the different locations of the guns also · different. This is caused by a correction device, which is shown in detail in FIG. -This device is connected between the counter marks e moving parts p and the drive spindle f for the gun to be set.

Wind for the purpose of setting a counter mark e (Fig. 4) on the pointer d, the shaft /, which carries a planet wheel η , rotates, the planet wheel: 0, which is connected to the shaft ^, causes an adjustment of the "counter mark e The mating gear q of the planetary gear is now not fixed, but makes one, e.g. B ^! . movement generated by the rotation of a cam disk I or the like

movement, so that the movement communicated by the wheel η to the drive bracket 0 is not transmitted directly to the shaft p , but with a sinusoidal correction or addition

. sentence.

For example, the disk I wdrjd, as can be seen in Fig. 4, is also driven by the shaft / from, and is used to move a rack r, which in turn causes the movement of the drive s and, through the transmission gears ν and w, the drive of the planetary rail q . ', Y shape of the effective part of the disc · I, in the present case of the slit, taking into account of the ratios' of the size and' is the correction due _r contactor in the setting of Ge. The length of the slot y varies depending on the location of the associated gun.

In this embodiment of the invention, the adjustment takes place according to the different distances of the target by changing the size of the slot y by changing the distance of the sliding roller χ guided in the slot y from the pivot point of the disk I by means of curve, segment or cable transmission u So that the correction corresponding to the distance is also transmitted by the toothed racks to the planetary gear and thus to the counter-pointer β.

In order to automatically take into account the various distances when setting the parallactic deviation, the curve transmission w can be adjusted by a drive k . This is in engagement with the device for adjusting the gun to the height direction.

The arrangement can also be made so that the adjustment of the guns takes place automatically. For this "purpose, for example, when the pointer d moves out of the normal position, contacts can turn closed, which close the circuits for the drive motors ■ for gun adjustment Pointer have taken a certain side direction.

It should be mentioned at the same time that the Transmitter and receiving devices fozw. Systems can be designed in any way, e.g. B. also · with multiple, pointers and Counter-pointers to unite coarse and. a fine adjustment to undertake.
