Abstract
14,431. Lohay, C. G. July 7. Sights and methods of sighting.-The predetermined movement of the back-sight of a gun is obtained by a motor the circuit of which is controlled by a switch which is opened by a second motor the operation of which is controlled by an electro-magnetic escapement. When several machines are to be operated, the arrangement is multiplied. The driven mechanism t is geared to the motor Y through worm-gearing b, c and pinions e,f. A disk s of insulating-material mounted upon a shaft d carries a series of spirally arranged contacts u, which control the successive energizations of an electro-magnetic escapement shown in Figs. 1 and 6. A motor X placed in parallel with the motor Y operates a device 3 through the medium of worm gearing 29, 35 to open the circuit of the motor Y after the number of revolutions has been made. To operate the motor Y to produce a certain movement in one direction, the switch J is moved an angular distance #, thereby bringing the lead m into contact with the conducting ring q and energizing one of the magnets of the reverser 47 to close the circuits of the motors. As the motor Y revolves, the contacts u on the disk s successively contact with the brush z mounted in a slide 42 movable in uprights 43, thereby intermittently energizing the coil of the magnet core 33. A spring 32 normally keeps the armature 31 from the core 33. As shown in Fig. 6, the motion of the spur-wheel 29 carrying the releasing-device 3 is locked by the armature 31 engaging with the groove 30. When the magnet 33 is energized, the armature is moved into the position 31<1> in the groove 30<1>, thereby allowing the wheel 29 to advance a distance 45. A further rotation of the plate s de-energizes the magnet 33, returning the armature 31 to the groove 30', which allows the wheel 29 to advance a further distance 46 corresponding to two divisions on a dial w. This motion continues until a bolt 3 carried upon the wheel 29 has moved through an angular distance # and comes opposite a hole 21, Fig. 5, in a frame 9 carrying a switch J, and by means of a spring, opens the switch, thereby interrupting the motor circuits. The handle 5 of the switch J is provided with a spring-actuated lever 23, Fig. 4, connected to a slide 24 carrying a heel 25 on its upper face and a cam 26 on its lower face. When the bar 23 is drawn inwards, the heel 25 lifts the bar j from the contact 18, while the cam 26 forces the bolt 3 from the base of the frame 9, thereby releasing it. When the handle is moved towards the right, the contact n engages with the contact o, Fig. 5, and the conducting-frames 10, 11 slide over the riogs q, r while the arch 15 of the bridge-piece 14 slides upon the ring k. When the lever 23 is released, the bar j is lowered into enlargements 18 of the contacts n, n<1>, and the motor circuits are completed. When the bolt 3 comes under the hole 21 in the frame 9, it forces the bar j from the contacts 18 by means of a spring, thereby breaking the motor circuits. Any number of similar mechanisms may be controlled by multiplying the number of arrangements, the disks 29 being mounted upon the same shaft which also carries a corresponding number of pointers 4.
