Title: Improvements in electric circuit breakers
IPC: H01H77/06
Filed: 1966-05-19
Abstract: 1,140,612. Automatic circuit breakers; gas blast switches; electromagnetic switches. GENERAL ELECTRIC CO. 19 May, 1966 [21 May, 1965], No. 22345/66. Heading H1N. An overload circuit breaker is provided with separable contacts 15, 16, 17 adjacent to a passage interconnecting an arc initiation chamber 63 and an arc extinction chamber 64, the walls of these chambers evolving hydrogen under the influence of the arc. The side walls 67 and the back wall 65 of the chambers are preferably of polyoxymethylene which produces hydrogen without free carbon. The chambers are sealed except for vents 67B and the gas produced consequently drives the arc rapidly towards a plurality of parallel copper or brass splitter plates 68. The movable contact 17 is mounted on a shaft 45 attached to the armature 46 of an electromagnet 50 which directly moves the contact 17 to the open position upon overload. The shaft 45 is connected to contact 17 and to armature 46 by lost motion devices 57, 60 and carries a cam member 44. A handle 30 moves, through an overcentre spring 47, a pair of spring blades 40 whose ends 43 normally engage with a groove 44A in member 44 to move it between the open and closed positions. When the shaft 45 is moved by the electromagnet its rapid movement disengages the blades 40 from member 44 and it moves to the open position without moving handle 30. The blades 40 subsequently contract around shaft 45 (Fig. 3, not shown) to prevent the contact rebounding to the closed position. In series with the contacts and the coil 24 of the electromagnet are a pair of blowout coils 18, 21 associated with cylindrical cores 69, 70 and Y-shaped polepieces 72 aligned with arc runners 15A, 16A in the arc extinguishing chamber. The handle 30 may be replaced by a power operating mechanism.

[Class 74 (ii)] A rotary auxiliary pattern drum for needle selection is provided in a circular machine in which the sequence of various operations is determined by a control drum or equivalent device, means being provided for rotating the auxiliary drum about its axis in a series of angular movements, one or some of which differ from another or others in extent so that the longest pattern, or a complete pattern which is shorter than the longest pattern, can be produced from one complete revolution of the drum. A shield 202 can be moved from a position in which it renders inoperative a pawl 104, into a first position in which the driving stroke of the pawl is so limited that the pattern drum 82 is racked round one tooth of the ratchet wheel 102, or into a second position, in which it is racked round two teeth. The first and second positions are determined by low and high studs respectively, on a pattern chain. In practice, the chain studs are arranged so that the number of movements the auxiliary drum makes in one revolution is equal to, or is a multiple of, the number of courses in the pattern. The number of high studs will be equal to the difference between the number of courses in the pattern and the number of teeth on the ratchet wheel, there being as many studs altogether as there are courses in the pattern. Preferably the high and low studs are grouped separately. When the drum is racked round two teeth of the ratchet wheel, an intermediate vertical row of patterning studs 114, has to pass the ends of selecting levers 120 without disturbing the pattern, and to this end their arrangement may be identical with that of the preceding row. The studs 114 are detachably secured in holes 116 in the drum, there being as many vertical rows as the ratchet wheel 102 has teeth. When a stud engages an end 119 of a pivoted lever 120, a cam 122 on its other end 121 is moved out of operation on the coacting needle selector. Specifications 15008 /00, [Class 74], 24290/12, 230,857, [both in Class 74 (ii)], 427,099, and 428,799, are referred to.

Abstract: 821,588. Gearing for stopping and starting machinery; securing stop-rings on shafts. COLLINS RADIO CO. July 15, 1957, No. 22396/57. Class 80 (2). A radio-tune shaft 11, the rotation of which is arrested in predetermined positions, carries a number of stop-rings 23 each having a single peripheral notch for engagement by an associated pawl (not shown), tightening a thumbscrew 31 urging a transverse bar 28 rightwards of the Figure against a gear 27 to clamp the stop-rings frictionally to the shaft and to the driven member 16b of a slip coupling 16 (not further described) having its input side fast with a gear 14 meshing a driving gear (not shown). On release of the thumb-screw 31, the stop-rings 23 are freed from the shaft 11 and simultaneously a click-over detent 50 is coupled to the shaft which can then be rotated by turning a knob 33. The click-over detent 50 comprises a spring disc 54 formed with holes 56 arranged in a circle and each containing a bearing ball 57 co-operating with similarly-arranged spaced holes 58 in a stationary casing. Fast with the spring disc 54 is a ring 51 having axially projecting lugs 67 which can engage notches 66 in a flanged hub 41 secured to the shaft 11. Tightening the thumb-screw 31 acts through a rod 64 within the shaft 11 to force the detent assembly 50 rightwards against bias of the spring disc 54 and thus disengages the lugs 67 from the notch 66, so that the shaft 11 is free of the detent 50. Release of the thumb-screw 31 allows the spring disc 54 to engage the lugs and notches 67, 66 so that turning the knob 33 and shaft 11 rotates the disc 54 &c., and the bearing balls 56 click in and out of the associated holes 58.
