Title: Improvements relating to clay pigeon traps
IPC: F41J9/20
Filed: 1966-02-25
Abstract: 1,074,410. Clay pigeon traps. S. GAGLIARDINI, O. TIRANTI and A. ANTONUCCI [trading as OFFICINA MECCANICA GAGLIARDINI-TIRANTI &c.] Feb. 25, 1966, No. 8450/66. Heading A6D. A trap for hurling clay pigeons comprises a longitudinal frame 1 on which two grips 3 and 4 are formed, a base element 2, and a hurling assembly pivoted via hub 7' about a bolt 5, the hurling assembly comprising a bell crank lever 7 having two arms 7a, 7b, the free end of the lever arm 7a being attached to one end of a helical tension spring 8, the.other end of which is hooked into an annular groove provided in the head of a bolt 9; the other lever arm 7b is secured by screws 10 to an elongated plate member 11 to which a guide member 12 is fastened by screws 13. This guide member 12 has a strip 14 of frictional material fastened to it and is spaced apart from the plate 11 by spacers 15, thus forming a guide channel for the base portion of the clay pigeons. The detent of the trap comprises a rigid tongue 16 extending from the hurling plate 11, and a trigger 17 pivoted at 18 in a cavity 19 formed in the base 2. The upper portion of the trigger engages the tongues 16 when the hurling plate is rotated clockwise until said tongue 16 abuts against a stop 20. Two inertia members 22 and 23 are secured to the ends of the base 2.

Title: Improved construction of apparatus for assembling parts of clips or holders for revolver cartridges
IPC: B25B27/00
Filed: 1919-04-04
Abstract: 139,910. Prideaux, W. de C. April 4, 1919. Ammunition receptacles.-Consists of an apparatus to facilitate the assemblage of the outer spring arms 1, Fig. 4, of clips for revolver ammunition of the kind described in Specification 22653/14. A post C on a frame A, Figs. 1 and 2, has a table D at its upper end to which six arms ex are pivoted at K. The lower portions of the arms pass through slots J in a vertically movable plate I, and their inner edges rest against a ring L movable with the plate 1. The plate and ring are slid on the post C against the pressure of a spring M by a stirrup N, which is fixed to the plate and actuated by a pedal. When the plate I is depressed, the upper ends of the, arms G are moved outwards, and the outer spring arms I of the cartridge clip are dropped into position between the arms G and are centred by an extension H of the post C. The plate I is then raised, so that the upper arms G move inwards through the slots 10 in the clip arms. A second lowering of the plate I, preceded by pushing down the spring arms, again moves the upper arms G outwards, thereby also opening out the clip arms, so that the disk 5 of the clip may be dropped readily over them, the arms being then in position to pass through the holes in the disk.

Abstract: 1306822 Photographic copying REPLICA ASSOCIATES INC 25 Feb 1970 [8 April 1969] 8967/70 Heading G2A [Also in Division F1] A pair of opposed flexible sheets, of which at least one is translucent, has means for releasably clamping their peripheral edges together to make an air-tight enclosure which can be evacuated. The arrangement is used for accurately locating patterns on a lay marker table so that they may be photographically copied. As shown, the lay marker table 10 comprises a frame 14 which has a number of horizontally disposed light sources (22), Fig.3 (not shown) therein. These support a flat transparent sheet 26 which forms the actual working surface of the table, and which has grid lines marked thereon. Over this is laid a transparent sheet 36, on which is laid in turn a number of original patterns 38, the reference grid enabling their positions to be accurately determined. A sheet 40 of light-sensitive material is now laid over sheet 36 and the patterns, and a final transparent cover sheet 42 is laid over the whole assembly. This is all sealed in position on the table by magnetic tape 44 along all four sides, so that the assembly is firmly fixed to the metal edges 20 of the table. At the same time this seals the edges of sheets 36 and 42 so that the space between them forms an air-tight enclosure. This space can be evacuated through a conduit attached to sheet 36 at an outlet 48. Sheet 42 has ridges 54 forming channels which facilitate the evacuation, after which the patterns and the light-sensitive sheet are held firmly in contact with each other, and also flattened firmly against the table top.

Title: Toroidal winding machine

IPC: H01F41/08
Filed: 1956-03-23
Abstract: 809,370. Winding toroidal coils. STANDARD TELEPHONES & CABLES Ltd. March 22, 1957 [March 23, 1956], No. 9148/56. Class 83 (4). A method of winding a length of wire on to a toroid is characterized in that the said length of wire is anchored at one end and is repeatedly engaged at intermediate points in its length and repeatedly transported in loop form around and through said toroid to form successive turns of a winding. One end of a length of wire 5 in a wire chamber 1 is passed through friction pads 4 at the end of the chamber, through a toroid 6 on which the wire is to be wound, and is anchored at 7. A pulley 3 is then moved around the toroid 6 so as first to engage the wire 5 between the chamber 1 and the toroid and then to carry the loop so formed around part of the toroid to a position to the right thereof, Fig. 1b. A hook 2 is then moved above the chamber 1 and through the toroid 6 to engage the loop around the pulley 3, Fig. 1c. The hook 2 then withdraws the wire through the toroid and into wire chamber 1 until the wire slips off the hook due to its finite length, Fig. 1d. Thus one turn is wound on the toroid 6 and for each further turn the cycle is repeated, the toroid being suitably rotated or reciprocated during winding. A split flexible material top may be fitted to the chamber 1 and the hook 2 may be inclined so that the slit closes up after it to hold the wire 5 captive. Another arrangement, Fig. 3, for winding a toroid 15 has a circular wire chamber 7 and a hook 9 carried by a suitably driven arm 10.
