Title: Improved method and apparatus for controlling the operation of automatic mechanism such as automatic guns on aircraft
IPC: F41A19/58
Filed: 1941-04-18
Abstract: 573,305. Automatic guns. DUNLOP RUBBER CO., Ltd., and TREVASKIS, H. April 18, 1941, No. 5039. [Class 92 (ii)] An electric-motor firing-unit for attachment to a machine gun comprises a continuouslyrunning motor and means controlled independently of the motor to cause transmission of mechanical energy momentarily from said motor to actuate the sear. In the form shown, the casing 3, Fig. 4, of the unit is attached to the gun, shown in dotted lines, at a position adjacent the sear x, the casing being fastened to a plate on the gun by a quick-release device not shown. The motor comprises a rotary armature 2, permanent magnet 13, and arcuate polepieces 14. The armature carries a small flywheel 16 having an eccentric projection 17 which momentarily engages one end of a lever 18, the other end of which is loosely mounted on a spindle 33. The central part of the lever 18 passes through a slot 21, Fig. 7, in a member 19 which is axially rotated by an electromagnet 25, Fig. 5, energized by pressing a remote firing button. This causes the lever 18, under the control of a timing cam 42, to move into the path of the projection 17 which moves the lever along the slot 21 and thereby effects rotation of a cam 29. This cam through a follower 35 and link 40 actuates the sear to release the breech block and fire the gun. The lever is then moved into the enlargement 22 of the slot 21 by a spring pusher 23 and thus occupies an inoperative position. When the firing button is released and the solenoid de-energized, the member 19 is rotated in the reverse direction by a spring 28. The lever 18 is then disengaged from the enlargement 22 and returns under the action of a torsion spring 34 to the inoperative position shown in Fig. 7, and the cam 29 rotates to release the link 40 and permit the sear to reengage the breech block in the open or cocked position. The separate electric leads for the armature and solenoid are connected to the unit at 46.-

Filed: 1957-02-15
Abstract: 818,970. Sewing machines. CLUETT, PEABODY & CO. Inc. Feb. 15, 1957, No. 5295/57. Class 112 In a lock stitch seam a predetermined amount of slackness is produced in the looptaker thread, to counteract the formation of seam shrinkage and stitch pucker in subsequent laundering of the fabric, by alternately holding the looptaker thread on opposite sides of the path of the stitching needle and of the seam during the formation of each successive stitch. Said holding is effected by moving a finger 35 back and forth across the path of the needle 6 into and out of engagement with the looptaker thread 39, said finger projecting in the direction of seam formation. The needle thread 38 is tightened along the upper surface of the fabric in the usual manner. Finger 35 is carried by the upper end of an arm 32 arranged to reciprocate transversely of the direction of work feed in a slot 33 formed in the throat plate 11 in front of the needle. Arm 32 is fixed to one end of a rod 28 slidable in a bracket 29, a pin 30 on the other end of rod 28 being disposed in a slot 27 formed at the lower end of a lever 23 pivoted at 24. A cam follower pin 26 on the upper end of lever 23 co-operates with a cam groove 22 formed in a cam drum 21 carried by a shaft 20 driven by gearing 17, 18, 19 from the main shaft 8 of the machine. The finger 35 is moved across the needle path each time the needle commences its descent, and consequently remains in contact with the loop-taker thread until the subsequently formed stitch has been set. The action of the feed dog then serves to move the stitch off the finger. The degree of slackness is determined by the stroke of rod 28, and said stroke may be varied by changing the cam drum 21. In a modification, Fig. 7, the finger is in the form of a length of wire 42 over which a plurality of stitches is formed.
