Application filed February 13, 1911. Serial No. 608,242.
T 0 all whom it may concern:
Be it known that I, BORIS SVISTOUNOFF, a subject of the Emperor of Russia, and residing at Woskresjenskaia Quai No. 30, Flat 8, St. Petersburg, Russia, have invented certain new and useful Improvements in and Relating to Sight-ing Devices for 'Machine.
Guns and the Like, of which the following is a specification.
This invention relates to sighting devices for quick firing and machine guns of the type in which the sight is automatically adjusted to a height corresponding to the range while the gun is being elevated or depressed.
The object of the present invention is to provide a simple and compact apparatus of the above kind.
The invention is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of the im proved apparatus, Fig. 2 is a front elevation as seen from the place where the gunner or operator is standing and Fig. 3 .is a section on the line A-B of Fig. 1.
According to the present invention the lever 7 which connects the sighting device to the trunnion 8 is provided with slots or recesses 19 with intervening strengthening ribs 20, and is formed with a cast-on boss 16 which receives a clamping screw 14 which works in a slot in a curved link 13 secured to the body of the gun.
The end of the lever 7 which is clamped to the eyepiece of the tripod or stand 9 of the gun is bent back upon itself so as to form a spring arm 18, so that the trunnion 8 passes through two eye pieces of the tripod, the rear end of the machine gun the lever 7 and the arm 18. The lever is clamped in position by means of a nut 15 which is cut obliquely and can be turned on the screw 10, which is secured to the lever 7 and passes through the spring arm 18, by means of the lever 11, thereby pressing against the ring 12 which is also cut obliquely. Both the nut 15 and the ring 12 are provided with shoulders 21, which prevent the nut 15 from slacking back. That side of the lever 7 which is in contact with the rear end of the gun is provided with a ring-shaped projec tion or extension 17 fitting into a recess provided in the rear end.
The sight is carried by the rack 2 which is guided in its movement by the casing 1 which is carried by the lever 7 Passing through the casing 1 is a pin 3 which carries a toothed pinion 4 and a toothed wheel 5 firmly connected together, the toothed wheel 5 engaging with the teeth of the rack 2, and the toothed pinion 4L engaging with the teeth of a curved rack 6 secured to the rear end of the gun. This arrangement allows of a greater range of movement of the rack 2 than is obtained by the previous con struction.
The device is operated as follows :F irst the gun and sight are laid on the target, the sight being clamped in zero position by screw 14: and the screw 10 being slackened. The lever 7 is then fixed by the handle 11, the screw 14: is slackened and the elevating gear set in operation. As the rear end of the gun sinks the curve 6 descends with it and turns the pinion 4. and the toothed wheel 5, so that the rack 2 is pushed out. The sighting line thus remains parallel to its original position for all aiming angles and therefore always remains trained on the target. The actuation of the elevating gear is stopped when the height of the automatically advancing sighting device corresponds to the distance of the target. IVhen the gun has to be trained on another target, the clamping screw 10 is slackened and the si hting device thus freed, when it sinks back to its zero position whereupon the laying is eltected as described above, or the screw let is tightened the clamping screw 10 slackened and the sighting line trained on the new target after which the screw 10 is tightened, the screw 14. slackened, and the gun is elevated or depressed by the elevating gear so as to adjust the sight to the height corresponding to the range.
Having now described my invention what I claim as new and desire to secure by Letters Patent is 1-. In a sighting device with independent sighting line for use with quick-tiring guns a stand supporting the gun, a lever connected at one end to said stand, a casing carried upon the other end of said lever, a rack slidably mounted within said'casing, a sight upon said rack, and means for automatically adjusting the rack in a vertical direction when the gun is moved in elevation.
2. In a sighting device with independent sighting line for use with quick-firing guns a stand support-ing the gun, a lever connect ed at one end to said stand, means for clamping said lever to the stand, a sight supported at the other end of said lever, and means for automatically adjusting said sight when the gun is moved in elevation, whereby the direction of the sighting line remains constant.
8. In a sighting device with independent sighting line for use with quick-firing guns horizontal trunnions for supporting the gun, a lever connected at one end to a horizontal trunnion, means for clamping said lever to the trunnion, a sight supported at the other end of said lever, and means for automatically adjusting said sight in a vertical direction when the gun is moved in elevation.
4. In a sighting device with independent sighting line for use with quick-firing guns a stand supporting the gun, a lever connected at one end to said stand, a casing at the other end of said lever, a pin passing through said casing, a toothed pinion carried upon said pin and a toothed wheel firmly connected thereto, a toothed rack upon the rear end of the gun and engaging with said toothed pinion, a rack slidably mounted within the casing and engaging with said toothed wheel, and a sight upon said rack.
5. In a sighting device with independent sighting line for use with quick firing guns horizontal trunnions for supporting the gun, a lever connected at one end to a horizontal trunnion, a sight supported at the other end of the lever, means for automatically adjusting said sight in a vertical direct-ion when the gun is moved in elevation, a spring arm formed upon the lever, a screw fixed to said lever and passing through its spring arm, a ring upon the spring arm, projections formed upon said ring, a nut. upon the screw, and projections upon said nut.
6. In a sighting device with independent sighting line for use with quick firing guns, a stand supporting the gun, a sight supported upon one end of a lever and which is automatically adjusted when the gun is moved in elevation, a clamping device at the other end of said lever, whereby it is secured to the stand of the gun, and a guide upon said gun for limiting the movement of the lever relatively to the gun.
7. In a sighting device with independent sighting line for use with quick firing guns horizontal trunnions for supporting the gun,
within the casing communicating motion from one rack to the other.
8. In a sighting device with independent sighting linefor use with quick firing guns horizontal trunnions for supporting the gun,
a slotted lever connected at one end to a.
horizontal trunnion, a clamping device for securing said lever to said trunnion, a casing formed upon the other end of said lever, a pin passing through said casing, a toothed pinion carried upon said pin and a toothed wheel firmly connected thereto, a toothed rack upon the rear end of the gun and engaging with said toothed pinion, a rack slidably mounted within the casing and en-v gaging with said toothed wheel, and a sight upon said rack.
9. In a sighting device with independent sighting line for use with quick firing guns a stand supporting the gun, a sight supported upon one end of a ribbed lever and which is automatically adjusted when the gun is moved in elevation, a clamping device at the other end of said lever, whereby it is secured to the stand of the gun, a guide upon said gun for limiting the movement of the lever relatively to the gun, a cast-on boss upon the lever, and an adjusting, screw within said boss working within said guide;
10. In a sighting device with independent sighting line for use with quick firing guns a stand supporting the gun, a sight supported upon one end of a slotted lever andwhich is automatically adjusted when the gun is moved in elevation, a clamping device at the other end of said lever, whereby it is secured to the stand of the gun, a guide upon said gun for limiting the movement of the lever relatively to the gun, a cast-0n boss. upon the lever, and an ad usting screw within said boss'working within said guide. 7
