Filed: 1937-05-05
Abstract: 495,315. Adjusting wireless apparatus. METCALFE, C. May 5, 1937, No. 12804. [Class 37] A radio receiver is provided with an indicator having station names and their corresponding tuning marks arranged in wave range groups, a tuning indicator co-operating with the marks and being independently operative throughout each range, and a common actuating means for the station indicator and range changer arranged so that successive presentation of each name singly occurs from group to group as the actuating member is operated. As shown, a carriage 16 carrying a pointer or cursor 30 over the station name indicator 12 moves along an upper frame member 15 secured to forwardly extending side flanges 10, 11 on uprights 8, 9, the name indicator 12 being of the curtain type on rollers 35, 36. Alternatively, the indicator can be in the form of a drum with suitable gearing. A cord drive 20 from the spindle 25 of the tuning condenser to the carriage 16 is controlled by coarse and fine tuning spindles 26, 28. Actuating mechanism 18 for the name indicator 12 and wave range switch is supported on a lower frame member 17 and comprises a spindle 37 in the hollow spindle of a range change switch. On spindle 37 is a wheel 42 meshing with a pinion 45 having projections 47, 48 engaging abutment 49 and forming limit stops, the shaft 64 of pinion 45 driving the scale rollers 35, 36 through gearing 55 ... 60. Pinion 45 also has pins 50 ... 52 engaging slots in a Geneva wheel 53 gearing with the wave range spindle. Roller 36 is under spring tension and a further spring 62 is provided so that the name indicator always remains in the position to which it is set. At each end of roller spindle 61 is a boss 70 connecting with an arm 76 through lost motion washers, the arm 76 being linked to pins 78 on a mask 81 that fills the aperture 32 in an escutcheon 31. The mask 81 has viewing apertures 83, 84, the latter registering with an enlarged part 34 of the aperture 32 in escutcheon 31. Further pins 85, 86 are spring-connected to points 89, 90 on the members 10, 11. The station indicator is of translucent material with the names in opaque ink, the tuning-marks almost filling the aperture 83 in the mask 81, and the names filling the aperture 84.

Title: Breech-action for firearms
IPC: F41A3/66
Filed: 1937-05-05
Abstract: 488,090. Breech actions for automatic guns and ordnance. BROWN, H. R. S. May 5, 1937, No. 12813/36. [Classes 92 (ii) and 119] The breech-block 11 of a firearm is of prismatic form, the crosssectional shape approximating to an isosceles triangle of which the greatest angle lies between 80 and 100‹, the seat 9 and the slideway 4 for the block corresponding in form to the sides thereof which include the said angle, whereby a short transverse movement of the block seats it in the locked position, and a small movement in the opposite direction moves it clear of the seat so that it may reciprocate along the slideway to effect extraction and feeding of the cartidges. The breech-block 11 and a plate 15, which moves along grooves 8 in the slideway, are slidably connected, by dovetail joints 14, 16 with an end face and the upper face, respectively, of a triangular carrier block 13, and are connected together by links 17. A projection 5 at the forward end of the under-portion of the slideway 4 serves for the attachment of a magazine. Upon sliding the plate 15 forwardly from the rear of the slideway, the breech-block engages the end of a cartridge from the magazine and feeds it into the barrel, and when the front face of the breech-block is within a short distance of the rear end of the barrel, a pin 25, Fig. 3, carried by the breech-block is pushed rearwardly to move a spring catch 26 on the carrier block out of engagement with a notch in the breech-block, the continued forward movement of the plate 15 causing the breech-block to be moved vertically downwards by the links 17, to engage with the seat 9. Retraction of the plate 15 raises the breech-block clear of its seating and then moves it longitudinally to effect extraction of the spent cartridge. The inclined contacting surfaces of the slideway and breechblock may be plane or stepped, and the rear face of the block may be grooved for engagement with corresponding ribs on the seating 9. The rear end of the barrel 20 is formed with a triangular portion 20<1>, having a cross-section similar to that of the breech-block, and which engages in the front of a recessed portion 3 of the stock in which the seating 9 is formed, and the barrel is secured in position by means of pins inserted through holes 21<1>, 24, at the forward and rear ends of parallel arms 2 of the stock, between which the barrel lies. The stock is preferably made of pressed metal. According to a modification, the carrier block may be dispensed with, the breech-block being connected to the plate 15 by parallel links or other suitable means.

Title: Improvements in counter-cylinders for jig conveyors
IPC: B65G27/00
Filed: 1927-05-12
Abstract: 271,099. Klerner, H. May 12, 1026, [Convention date]. Compressed-air engines. - In shaking-shoot motors wherein the upstroke is effected by a piston in a cylinder M with a fluid-actuated valve, the down-stroke is effected by a counter-cylinder G which is provided with a fluid-actuated distributing-valve which may be controlled or put out of action so that the counter-cylinder may act as an adjustable motor element or merely as a fluidactuated spring. When compressed air enters the cylinder M by passages 17, 10 the shoot is raised contrary to the direction of transport until the piston 2 passes the port 14 when fluid pressure passes through passages 12 to the back of the annular head on the valve and effects its reversal, thereby cutting off the air supply; at the same time piston 2 of cylinder G moves to the left and the air in the cylinder exhausts through the port 7, passage 5 and outlet A until port 7 is closed when the air is compressed and the valve is thereby reversed. The left hand of the cylinder G then communicates with the supply main and the compressed air is forced back into the piping by the energy of the moving shoot until the main valve of cylinder M is reversed and the cylinder put to exhaust. The pistons 2 of the shoot then move to the right until the port 13 is opened and the valve of cylinder G reversed. If the working motor is initially too strong, for example, with a short shoot, the apertures 13, 14 of cylinder G are closed by valves 15, 16. The piston 2 therein then reciprocates with the main air pressure acting on its working area. The valves may be wholly or in part positively actuated.

Abstract: 1,005,003. Mobile collapsible jib cranes. KOEHRING CO. April 4, 1962, No. 12968/62. Heading B8B. In a mobile jib crane, having a jib composed of two parts 11, 22, Fig. 4, hinged together by an offset pivot 21 so that the two halves can be folded down parallel to each other, the jib is erected from the travelling position, Fig. 1, by a cable 50, Fig. 4, which passes round lever arms 53, 56 between the outer tip of the jib 30 and hoisting tackle 52, 72. To erect the jib, arms 41, 42, Fig. 1, are raised to the dotted line position and held there by pins 44. With a winding drum 85, Fig. 6, braked, the jib is raised to the position shown in Fig. 3 by a double winding drum 65, Fig. 6, which acts through sheaves 52, 72 on cables 50, 51. The arms 41, 42 are next pinned to the crane base at 118. So that the cable 64, Fig. 6, may be kept short, with a consequent reduction in the size and cost of the double drum 65, a smaller and cheaper drum 85 is used to wind in an interconnected cable 86, with the drum 65 running free, so that the sheave 72 is moved away from the sheave 52, compare Figs. 3, 4, ready for the next part of the erecting routine. The drum 85 is now braked and the jib part 22 is raised by the drum 65. Pivoting of the lever arms 53, 56 during the raising of jib 22 is such as to increase the moment arm as the jib approaches a horizontal position. The crane runs on a turntable 6 and outriggers 8, 9, Fig. 1, are provided. A welded construction is used with square section tubular chord members 23 and round section tubular lacing members 24.
