Specification of Letters Patent.
Patented May it, 1912.
Application filed May 25, 1911. Serial No. 629,403.
To all whom it may concern;
Be it known that I, EMIL Mi'jnnnn, engineer, a subjectof the German Emperor, residing at 83 Collenbachstrasse, Dusseldorf, Germany, have invented certain new and useful Improvements in Firing Devices for Guns with Differential Recoils; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
Guns with differential recoil are generally fired by the trigger lever coming into contact wit-h a fixed stop shortly before the end of the run out motion; the trigger lever is consequently operated and the charge is fired. Should a mis-fire occur the energy of the running out movement is not absorbed by the recoil of the gun after firing but the gun is urged with great force by the spring or air accumulators to the end of its path and may very possibly be forced out of its direction. The trigger must then be released a second or third time by hand until at last the charge is fired. The whole energy of the recoil must then be absorbed in the comparatively short recoil stroke ar- "anged for guns with differential recoil, since the running out movement is finished and consequently the force due to the recoil will be twice as great as if the charge were fired during the run out. The present invention avoids this drawback by an arrangement in which the members which bring about the automatic firing are so constructed that the trigger lever is repeatedly operated during the course of the run out.
A. constructional form of the invention is represented in the accompanying drawings in which- Figure 1 is a side view of the gun in a horizontal position, Fig. 2 is a section across the line 2-2 of Fig. 1, Fig. 3 represents the gun with the barrel in an inclined position. The fixed piece a, encountered by the trigger lever 29 during the running out movement is provided according to the invention with several teeth or projections which cause the trigger lever Z; to be operated several times in quick succession during the forward movement, so that it is possible and probable that an effective firing will occur, even if a mis-fire has occurred the first time. The trigger lever is so arranged that it is drawn back during the forward movement by the teeth of the fixed piece a; while during the recoil it can be displaced by a certain angle in the direction of the arrow shown in Fig. 1, so as to avoid the projections of the piece a. The arrangement can obviously be altered so that there are several teeth on the trigger lever and only one on the fixed support.
In the constructional form shown the firing support a is adapted to be automatically displaced so that as the elevation is increased the course traversed before the firing position is reached will be increased, in order to prevent the longer recoil of the gun, due to its greater elevation, from running the gun beyond the cradle. For this purpose the firing support a can slide in guides c in the cradle and is linked through a connecting rod (Z with a point e of the carriage situated above the trunnions. By this de vice the firing support a is drawn fart-her forward on the cradle as the gun is elevated, so that the distance the gun is run out before it reached the firing position is automatically increased.
I claim as my invention:
1. A firing device for differential recoil guns comprising, in combination with a barrel, a trigger lever, and means cooperating wit-h the trigger lever for repeatedly operating it during the run out of the barrel.
2. A firing device for differential recoil guns comprising, in combination with a barrel, a trigger lever, and a series of teeth for operating the trigger lever during the run out of the barrel.
3. A. firing device for differential recoil guns comprising, in combination with a barrel, a trigger lever, and a plate for cooperat ing with said trigger lever and having means for operating itseveral times during the run out movement of the barrel, and means for automatically displacing said plate relatively to the barrel according to the elevation of the latter.
l. In combination with abarrel, the cradle therefor, and means pivotally supporting the cradle, of a trigger lever carried by the barrel, a plate slidably mounted on the cradle and having a series of teeth with which the trigger lever is designed to engage 0n the run out of the barrel, and a link pivotally connecting said plate and the cradle support ata point above the pivot of the craclle In testimony whereof, I have signed this l for automatically changing the position of WV1tnesses:
