KARL MAU, OF FORSTHAUS KOL'LHOF, NEAR PUTBUS, GERMANY.
AUTOMATIC FIREARM WITH SLIDING BARREL AND A BACK-SIGHT BAR CARRYING THE FORESIGHT.
Specification of Letters Patent.
Patented June 16, 1914.
of this type, the back-sight bar is firmly soldered to the barrel. This arrangement has several disadvantages. First of all,-the.
weight of the masses moved to and fro when firing is increased by the back-sight bar, so that a considerable surplus of work is imposed upon the cartridge during the short time of its function and also upon the forwardly propelling spring. During the movements of the barrel, which, in connection with this arrangement, the back-sight bar must follow, the eye of the marksman, which observes these movements, is disturbed and above all things by the moving foresight on the front end of the back-sight bar. The heating of the barrel due to the firing is rapidly transmitted to the backsight bar connected to the barrel, so that a dazzling of the eyes takes place, which in terferes with the aiming.
Now the invention consists essentially in that the backsight bar is supported on the receiver and connected to the barrel in such a manner that the back-sight bar does not participate in the movements of the barrel.
The back-sight bar covers the barrel like an umbrella and prevents the eye of the marksman being interfered with. As the back-sight bar does not move with the barrel, no additional load is imposed on the cartridge and the forwardly propelling spring. In connection with this arrangement the back-sight bar may be formed of thin spring-steel, so that the total weight of the fire arm is only slightly increased.
The invention is shown in the accompanying drawing by way of example.
Figures 1 and 2 are side elevation and plan respectively of a self-loading gun constructed according to this invention. Figs. 3 and 4 are side elevation and plan respectively of the back-sight bar only. Another modification of the invention is shown in Figs. 59. Figs. 5 and 6 are elevation and plan respectively of the front part of the fire arm with the back-sight bar. Fig. 7 represents the removed back-sight bar on an enlarged scale, as seen from below. Fig. 8 is a section taken on line AB of Fig. 7, and, Fig. 9 is an elevation of the barrel with the back-sight bar removed.
In the modification according to Figs. 14, a guide-bar h is secured to the front end of the barrel Z. The back-sight bar a, which carries the foresight c in front, embraces the said guide-bar h with its correspondingly enlarged flanged front end f and also the barrel Z with a clamp-like member 6 formed in the middle.
The rear part of the back-sight bar is provided with abutments c engaging in recesses of the receiver, also with two lateral clamps d, which bear resiliently behind the front ribs of the receiver, so that the backsight bar can be easily removed from the recelver.
The back-sight bar may be slipped over the barrel in front and when slipped over, it is then completely secured in position. It can also be readily interchanged so that when. hunting, a barrel with a wide bore may be replaced by a barrel with a narrow bore without using special tools.
In order to adapt the back-sight bar to the different lengths of barrels, it can be made according to the constructional form shown in Figs. 5-9. According to this modification, the back-sight bar is formed of two parts a a the part a being fixed or detachably mounted on the receiver by means of abutments c and clamps d in a similar manner to the first constructional form. The other part a of the back-sight bar is preferably bent out of sheet steel in U form and embraces the front end of the part a (Fig. 8) of the bar, also two guide-bars k 72, (Fig. 9) secured to the barrel. The backsight bar is bent together at these embracing or engaging points so that three guidepaths 7 f f are formed on the back-sight bar (Fig. 7).
For the purpose of connecting the two parts a a of the back-sight bar, there is provided on the front part a a spring plate 21 having holes in which pins k engage, the
holding pins 70 are allowed to engage in the 7 holes of the locking plate z at a suitable point.
The whole barrel length can thus always be used as sight path.
I claim 1. In an automatic firearm, the combination with the sliding-barrel and receiver thereof, of a sight-bar having a fixed engagement with said receiver and a sliding engagement with said sliding-barrel, and sighting means carried wholly-by said sightbar.
2. In an automatiefirearm the combina- 3. In an automatic firearm, the combination with the sliding-barrel and thereceiver thereof, of a sight-bar havlng a fixed engagement With said receiver and a sliding support on sa1d sliding-barrel, and sighting ,means CZLI'I'IGCl'SOlQlY by sa1d s1ght-bar, sa1d sight-bar consisting of sections adjustably locked together to permit the use of sa1d sight-bar on barrels of different lengths.
In testimony whereof I have aflixed my signature in presence of two witnesses.
