To all whom t may concern:

Be it known that I, WILHELM RoEDiiR, en-

' ineer a citizen of German residin at g a y:

Hanover, Germany, have invented new and useful Improvements in Automatically-Operated Guns for Soaring Birds or Like Purposes, of which the following is a specification.

This invention relates to automatically operated guns for scaring birds, ysignaling or like purposes, of the type in which the lock-V ing members of a series of striking bolts disl`posed side by side are operated by clockwork to release the striking bolts consecutively and so discharge the cartridges.

In a previous construction the locking members after being released by the clockwork hadto be replaced singly by hand to retain the striking bolts in their raised position, but this arrangement occupied considerable time and there was alwa sa chance of the striking bolts being ine ciently `re-V tainedso-that the vibration of the apparatus after the first cartridge had been discharged was liable to release some of the other strikwhenv the striking bolts had been properly made to engage their retaining members the vibration caused by firing loosened theremaining locking members which usually engaged grooves formed on the striking bolts.

According to this invention these disadvantages are obviated by the locking members being automatically forced into grooves on the striking bolts by means of springs. Further, rotating tappets first employed for moving the striking mechanismV with such' Vguns in connection with a primer band travcling under a striking member, are according to this invention used with a cam shaft for actuating the locking members. The

` arrangement according to the present invention is such that the device can be used in any position without danger'of premature show a construction of apparatus according release of the striking bolts, and further to reset the striking bolts it is merely necessary to .pull them upward into their raised position, their retention in this position being automatically effected by the spring-conti'olled locking members; further any loosening of the retaining members is prevented by means of these springs.

In the accompanying drawings Vwhich to this invention, Figure l is a cross section taken on the line A-B of Fig. 2. Fig. 2

yadvance the plate z' the bolts f can freely is a plan. Fig. 3 is a section on the line C-D of Fig. 2, and Fig. 4 shows a cartridge carrier in side elevation.

A casing a is provided for clock-work ymechanism b which rotates a spindle c on which are mounted a number of tappets Z which successively shift locking members e when the spindle rotates so that the striking boltsf are released and strike the pins of cartridges 7L in the carrier g. The locking members e carry plates z' which are slotted at k, the dimensions of the slot being such that when the striking bolts are in their raised position as in Fig. 3 the eX- Ytremities of the plate z' engage grooves Z formed on the striking bolts. As soon, however, as the locking member e has been moved against the action of its spring n to pass through the widened portion of the slot if: under the action of a coiled spring m. Vhen the bolt has again been pulled up, the spring n forces the locking member e back intoits normal position and so moves the plate into the position shown in Fig. 3

where it willengage the groove Z when the striking bolt is again raised.

The cartridge carrier or magazine g can easily be removed for purposes of i'e-chargingor cleaning; the clock-Work b may be disposed in the center of the casing a. or in 1 other desired position as may be found most convenient.

That I claim is:

l. A device of the character described, comprising a cartridge magazine, a series of spring-influenced bolts, a series of springinfluenced locking-members adapted to engage tlie bolts, a rotatable spindle, and tappets on the spindle adapted to successively actuate the locking-members.

2. A device of the character described, comprising a cartridge magazine, a series of grooved spring-influenced bolts, a series of spring-influenced locking-members having elongated slots adapted to engage the bolts, a rotatable spindle, and tappets on the spindle adapted to successively actuate the locking-members.

Signed by me at Hanover Germany this 3 day of April 1909.
