PATENT OFFICE.

The patent no. The air pressure ignition system laid down in 36442 runs the most diverse Embodiments and a number of the same are presented here.

First, the inventor has the construction of the device for the safe launching of rifles, as shown in Fig. 2 to 5 of patent no. 36442 is subject to simplification; the new device is shown in FIGS. 1 and 2 of the accompanying drawings and is readily understandable. If the air in the line c ^{1 is} compressed by a corresponding pressure, the balloon G ¹ inflates and presses against the upper part U ^{1 of} the envelope swinging around the pivot point d ^1; as a result, the trigger s of the rifle is moved by the spring r ^1, which is connected to U ¹ and can be adjusted by adjusting screw s ¹ , and the rifle then arrives at the gun in a known manner.

The inventor then changed this device and used the resulting new construction to ignite artillery pieces. 3 and 4 show the device as one must think of it to be placed on the vertically arranged ignition hole of a cannon. By the air pressure in the line c, the balloon ² G ² is inflated and pressed against as a result, the hinge ² to d rotatable lever Z7. ² This will. the Arretirung r ² of the tensioned spring F ² subtracted out. that the latter can exert its power unhindered and pulls the grater y out of the hammer tube in the direction of the arrow, as is otherwise effected by the artilleryman by means of the trigger cord. The Frictionssatz ignites the fire propagates in the firing tube \ continued and ignites the charge, the Schufs DAF's done.

In the case of cannons with oblique ignition, the device shown in FIGS. 5 and 6 is attached to the upper part of the ignition screw T.

If the balloon G ⁹ is inflated by pressure in the line c , the angle lever R ⁹ presses on the angle lever r ⁹ and pulls the latter away from the tensioned spring F ⁹ , so that it can freely utter its force and by means of the connecting chain y ^x the friction the beater tube pulls out, causing the ignition to take place.

In the case of gun constructions with central ignition, the friction ignition screw lies in the axis of the barrel, and the device shown in FIG. 7 can be used here. By inflating the balloon G ¹⁰ , the angle lever R ^w is moved so that the nose r ¹⁰ slides into the opening o ^{10 of} the tensioned spring F ¹⁰ ; the latter snaps back as a result and the connecting chain y ² attached to F ^w has a pulling effect on the friction so that the ignition must take place.

FIGS. 8 to 17 show various applications of the system to the ignition of cartridges, mine charges, fireworks, etc. ' ■■ .'-- ■

If, for example, one imagines the device in FIG. 8 placed on the dynamite charge of a borehole and the end χ of the rubber balloon G ³ connected to the surface through a solid tube x ^l made of paper, wood or metal, etc., one can easily go through Connection of a second elastic balloon or in some other way ^{exert pressure on the air contained in the balloon G 3} , whereby the locking piston R ³ with its locking pin r ^{3 is} advanced in the sleeve A , so that r ³ is in the slot e of the tensioned spring F ³ lays, so the latter is exposed and has to hit the squib £ ^{3 with the tip;} the fire of the latter is then transferred in a known manner to the charge in the borehole.

In the device in Fig. 9, when G ⁴ is inflated, the inner sleeve R ⁱ with the corresponding slot provided with the squib ^ ^{4 is} slightly displaced, thereby causing the tensioned spring F * firmly connected to the outer sleeve A ^{1 to} slide off the Edge r ^{4 of} the sleeve i? ⁴ brought. The tip of the spring strikes the squib and ignition takes place.

The ignition device shown in Figs. 8 and 9 can be modified from that given in Fig. Ga. By inflating the balloon G ^{10 w} through a slot of the spring F continuous Arretirhebel R ^u is raised, the latter thereby rotates i around the tip, so the approach DAF r ¹⁰ of the striker spring F slides ¹⁰ and located in the in F ¹⁰ Insert slot e ² . The biased spring F ¹⁰ is no longer retained as a result, it proposes rather low on the primer \ ^10, this ignites the ignition and propagates through the tube in the powder u given to the explosive charge on.

10 shows a construction in which a conical piston R ⁵ is displaced by the inflation of the balloon G ^5. As a result, the locking springs r ⁵ are pressed from each other so that they can pass through the corresponding openings in the plate A ² . The tensioned helical spring F ⁵ can thus freely utter its force and hurl the anvil α connected ^{to r 5} r ⁵ onto the squib ^ ⁵ , whereby the ignition takes place.

Figs. 11 and 12 show a device similar to the previous one, only it is not intended to serve for single use as the well-mounted devices in Figs Serving purposes of the most varied nature. By an exerted pressure in the line, the spring R ^{e is lifted by means of the balloon G 6} , so that the projection r ^{6 of} this spring is detached from the cross piece b of the bolt ^ ⁶ , whereby the latter is thrown forward by the force of the tensioned spring and that the piston p hits the primer, through which the further ignition is effected.

Fig. 13 shows an ignition in which the piston R ^{7 pushed forward by the inflation of G 7} with its rod r ⁷ , which is provided with an ignition charge at its end, pushes itself with some force into an opening O, the wall of which is covered with a friction compound or presents another friction surface. The resulting friction ignites the ignition charge of the rod r ⁷ , which then further ignites the cartridge, etc.; or vice versa, r ^{7 can} also be provided with a friction surface and opening 0 contains only one ignition charge.

Figs. 14, 15 and 16 show different ones Facilities for blasting on the surface.

Fig. 14 assumes the arrangement of the apparatus in a vertical position. By means of compressing the balloon G exerted pressure of the air in the line c ³ of the piston ¹ to K through the opening O \ D in the pipe is lifted ^1, wherein the excess air can flow out through o. ¹ Then the balloon G released, the result is below K ¹ by the return taking place swelling of G an air dilution; so that K ^ fall freely and h on the primer can beat ^l or any squib, the ignition DAF done must,.

The horizontal arrangement of the device in FIG. 15 enables the piston K ² to be thrown forward directly in the pipe D ² by means of the pressure generated ^{in the line c 4 , the air trapped in D 2 in} front of the piston having to be directed outwards in an appropriate manner , e.g. B. through opening o ² . The piston K * hits the primer h ² and thereby ignites the cartridge etc.

The device in FIG. 16 can be arranged in any position. By pressure in the line c ⁵ as a result of the lifting Schlauchbalges G i ⁸ of the Arretirhebel? ⁸ rotated about its fulcrum d ^s , whereby the second lever end r ⁸ , which locks the piston K ³ under pressure from the spring F ⁸ , lifts out of the tube D ³ , so that K ³ becomes strong as a result of the pressure of the spring F ⁸ Able to strike and

the primer h ³ hits through, causing the ignition.

In Fig. 17 it is shown how the ignition of a series of charges in a mining installation can be effected from one point at the same time. If air is compressed by compressing a balloon g or in some other suitable manner, the pressure produced thereby is propagated in the flexible tube c ^e to a solid tube c ⁷ . From here the pressure is transmitted onward through as many branch lines c ⁸ as there are charge points L. Each branch line now acts as its own main line in the manner explained above, so that the described effect is produced simultaneously in all of the apparatus attached to the points LL and an explosion takes place in the entire system.

It is of course not excluded, the elements explained for air pressure ignition to combine in an appropriate manner and the parts of one apparatus with equivalent parts of another apparatus to replace. The details can be changed in various ways and specific to each individual In the event that the most suitable material can be used in order to achieve this to bring the costs of the establishment in the right proportion to the achievement, so that a price increase in the use of air pressure ignition compared to the hitherto customary Devices for the ignition by means of fuse cord, electrical line, etc. does not arise or is canceled out by the advantages offered.
