Patent GB-163955-A (GB)
Abstract: 163,955. Paterson, W. G. Oct. 8, 1920. Teaching small-arm shooting; machine and aiming rests.-Relates to aiming-practice devices of the kind in which a rifle, revolver, &c. is mounted to swivel on a fixed stand or base and is provided with means for spotting the aim taken on a distant target by means of projected light; and consists of means for locking the gun in position and for spotting the aim taken when the trigger is pulled. Coin-freed mechanism may be provided for controlling the operation of the apparatus. In the form shown, the gun has a depending plate 1 pivoted at 2 in supports 3 rotatable in azimuth on a base B. The plate 1 has serrations co-operating with a knife-edge 4 carried by arm 6 pivoted at 7 to the base B. Arms 11, Fig. 3, fixed to the supports 3 carry a serrated cross-piece 10 co-operating with a knife-edge 12 on a plate 13 capable of depression in a bracket 14 against a spring 15 by pressing a knob 17. The gun is fitted with a lens 47 and an electric lamp 46 connected to a battery 21 through switch arms 22, 23, the arm 23, which is pivoted at 24 and weighted, being normally held out of contact with the arm 22 by a lever 25 weighted at 28. A coin placed in a shoot 32, Fig. 9, deflects horizontally a lever 33 which withdraws a locking-rod 36 from the slidable plate 13. Pressure on the knob 17 then depresses this plate withdrawing the knifeedge 12 from the piece 10 and freeing the gun supports 3 for azimuthal movement. Simultaneously, the lower end of a sear 8 pivoted at 9 to the supports 3, and actuated by a spring 18, rides up the inclined forward end of the plate 13, first moving a cross-piece 19 carried by the sear away from the arms 6 and permitting them to drop by gravity to release the knife-edge 4 from the serrations on the plate 1 and free the gun for elevation movements, and then mounting the end of the plate to maintain it in depressed position. The coin is retained in the shoot 32 by a spring-actuated plate 38 during the operation of aiming. On pulling the trigger, the sear 8 is tripped from the end of the plate 13, which rises under the action of the spring 15. Its inclined forward end wipes along the lower end of the sear 8, forcing this forward to cause the crosspiece 19 to raise the arms 6 to lock the gun in elevation. When the plate 13 reaches its uppermost position, the knife-edge 12 locks the gun in azimuth. During the upward movement of the plate, a projection 42 thereon trips past a spring- piece 41 and causes the guard-plate 38 to turn momentarily from the shoot 32 so that the coin drops into a pan 44 on the other end of the lever 25. The lever 33 is thereby released, causing the bolt 36 to lock the plate 13. The weight of the coin causes the lever 25 slowly to rotate and the initial movement releases the switch arm 23, which turns into contact with the arm 22 closing the circuit and causing the lamp 46 to project a spot of light on the target. When the lever 25 has passed its horizontal position, the coin drops into a receptacle 45, and the lever 25 then returns to its original position and cuts off the light.

Abstract: 736,566. Dynamometers. VYVOJ TVARECICH STROJU NARODNI PODNIK. June 15, 1953, No. 16408/53. Class 106 (2). An apparatus for measuring the tension of warp threads in a loom comprises a central comb 2 movable with respect to two parallel outer combs 1, the combs having teeth adapted to fit between the warp threads. The combs are interconnected by links 3 and springs 6 are used to bias the central comb 2 to the left relatively to the outer combs 1. In operation, a slide 7 is moved along the comb 2 to abut a stop 9. The outer combs 1 are then in the position shown in chain lines with respect to the comb 2. The apparatus is lowered on to the warp threads so that the teeth extend therebetween and the springs 6 are allowed to displace the combs and hence the warp threads. The tension in the threads may be determined from the relative displacement of the combs. The initial tension of the springs 6 may be varied by adjusting a cross-arm 5, on which they are mounted, relatively to the comb 2.
