MACHINE GUN Filed May 13, 1921 atvented Feb. 20, 1923..
UNITED STATES ERNST LUDORF, O BERNE, SWITZERLAND.
MACHINE GUN.
' Application led May 13,
Z'o all whomz't may concern.'
Be it known that I, ERNST LUDORF, a citizen of the German Re ublic, Yresiding at Berne, Engerstrasse o. 6a, Switzerland, have invented new and useful Improvements in Machine Guns, of whlch the following is a description.
The present invention relates to an automatic machine gun.
One object of the invention., is to prov'ide a machine gun of very greatly simplified construction in which the number of Working parts is very small, the gun being thoroughly eicient in operation and of very light weight.
A further object of the invention consists in the provision of means to damp the recoil in such a manner that the initial speed olf the projectiles leaving the muzzle of the gun is the same in vertical or hori zontal position of the gun.
Another object of the invention consists in providing a Huid brake of an improved construction which is of light weight and very compact.
y A further object of the invention consists in the provision of means to feed the projectiles positively into the gun.
With these and y other objects in View the invention resides in the parts and combination of parts hereinafter described and particularly set forth. in the claims appended hereto.
In thedrawings which form a part of this specification:
Fig. 1 is a partial sectional elevation of an automatic machine gun, the breech casing being closed.'
F ig. 2 is a partialV sectional elevation of the gun showing a section on line Gr--H of Fig. 1, the breech case being open.
Fig. 3 is a section on line A-B of Fig. 1 showing the breech casing with the Huid brake. l
Fig. 4 is a section on line C-D of Fig.
1 showing the fluid brake.
1921. Serial N0. 469,275.
firing pini8' being released is thrown forward by the spring 9 and fires the cartridge 7 which has been inserted in the chamber ber 19 andfrom the chamber 19 through the'bore -20 into the cylinder 4. By the rearward movement of the piston 17 the spring 25 is-compressed, the slide 12 which rests on the-lug 14 is brought back to its initial position, until it falls behind the.
The device to feed the cartridge comprises a slide 32 having an arm 33 slidably mounted in the breech casing and project' ing with its free end into the path of the lug 14. If the breech bolt 5 moves rearwardly the slide 32 takes part in thismovement.v The slide32 is provided with cams 34 adapted to swing a double armed lever 35, 36 about its pivot. "The arm 36 pushes cartridges 7 which are fed by al channel 37 into the slot 38 one by one into said barrel chamber in front of the breech bolt 5.
The empty' cartridge case is thrown out throughthe slot 38. The slide 32 is brought back toits initial position by a spring suitabl arranged.
'IYo insert the first cartridge the nut-40 is 1,44e,ase
unscrewed, the cylinder v4 with the breech bolt 5 is withdrawn and the one cartridge inserted through the channel 37.
The slide 21v frees the bore 2O only after the cartridge has been fired, thus the fluid has to withstand the gas pressure.'
I wish to point out that various changes may be made without departing from the spirit of my invention. 'i
What I claim and wish to secure by Letters Patent is I Y 1. A machine gun of the kind hereinbefore referred to having a barrel, a breech casing, a breech bolt slidably arranged in said breech casing, a cylinder co-axial ;to said breech bolt, a piston on said breech bolt slidable inv said cylinder, a fluid within said cylinder, said cylinder having openings beyond the limits of the movement of the piston, a slide governing one of said openings and operating means for said slide, said operating means actuated by the breech bolt to open 'and close said opening.
2. A machine gun of the kind hereinbefore referred to having a barrel, -a breech casing, a breech bolt slidably arranged in said breech casing, a cylinder coaxial to said breech bolt, a piston on said breech bolt slidable in said cylinder,'a fluid within said cylinder, said cylinder having openings beyond the limits lof movement of the-piston, said cylinder and piston having rectangular cross-section, the cross-section decreasing gradually, a slide in said piston, and a spring acting on said slide to progressively piston.
3. A machine gun of the kind hereinbefore referred to having a barrel, a breech casing, a breech bolt slidably arranged in sard breech casing, a cylinder co-axial to said breech bolt, a piston on said breech bolt slidable in said cylinder, a fluid within said cylinder, said cylinder having openings bebrake the rearward movement of theV yond the limits of movement of the piston, 4
a slide governing one of said openings, a lug on the breech bolt co-acting with said slide, and means for automatically discon-v necting said slide from the breech bolt.
In witness whereof I aiiix my signature.
ERNST LUDORF.
