Title: Improvements in or relating to electrically operated switch, crossing gate and like machines for railway and other purposes
IPC: B61L7/06
Filed: 1926-12-06
Abstract: 286,375. British Power Railway Signal Co., Ltd., Glenn, S. L., and Pierce, E. E. Dec. 6, 1926. Electric operation. - An electrically-operated machine for railway points, level-crossing gates, and swing or lift bridge bolts, of the. kind described in Specification 251,339, has a non- - intermittent drive to the power bar and has a pole-changer actuated by a cam-slot connection having sloping ends and intermediate, straight part, the lock-bar being omitted. The machine may be manually operated by a handle applied to the armature shaft of the electric motor 1, as in Specification 284,817, or by a hand-crank applied to the large bevel wheel 30 Fig. 9, or both means may be provided. Application of the hand-crank can only be effected by raising a plate 42 which rotates a shaft carrying an insulated contact 49 bridging contacts 47, 48 in the motor circuit. The power bar 4, Fig. 2. is driven by a stud-and-notch gear, or by a rack 15 and pinion 14, the pole-changer 3 having a pin 12 engaging a cam slot 5 in the bar 4. To provide for alteration in the stroke of the bar 4, it has a detachable plate 16, Fig. 4, carrying one end of the cam-slot, this plate being replaced by one having a different slot. The rack plate may also be changed if desired. To enable the apparatus to be moved by hand without rotating the whole of the gearing, bevel wheel 30, Fig. 2 is raised out of engagement with bevel pinion 32 by arms 36 on a shaft 35 rotated by a hand-lever 18. This lever carries an arm 27, Fig. 6, having a lug 28 passing through a recess 29 in the power bar 4 so that the lever can only be moved when the power bar is in normal position. The lever is held by a spring bolt 22 which engages notches 25, 26 of different depths, and carries a lock 19 with bolt 24 which can enter a recess in bolt 22 only when bolt 22 is in notch 25; the key being retained in the lock until bolt 24 is shot home. Shaft 35, Fig. 2, also carries an arm 42 which actuates a circuit-breaker 20.

Abstract: 499,953. Vehicle spring-suspensions. HUEPER, A. Oct. 27, 1938, No. 31089. [Glass 108(ii)] A spring-suspension for vehicles has a blade spring 11, Fig. 2, parallel to the axle and, in the same plane, upstanding auxiliary springs 12 and 13, which directly or indirectly bear slidingly and supportingly against a transverse girder 1 or other sprung part of the vehicle. Support against lateral movement, and friction damping against vertical movement are thus provided. The upstanding springs may be inclined or provided with stops to limit vertical travel of the sprung part of the vehicle. In a modification, Fig. 3, helical springs 22 acting in conjunction with levers 18 are employed in combination with the main leaf spring 11. When desired, the springs may be removed and the transverse girder 1 fixed directly on the flanges 9, 10, of the axle.

Abstract: 461,925. Extensible tables. GILES, N. S. Nov. 11, 1935, No. 31144. Convention date, Nov. 12, 1934. [Class 52 (iii)] In a table top of the kind comprising end sections 21, 22 with a centre section 26 adapted to be stowed beneath their inner parts, the end parts 21, 22 are fitted on their undersides with pairs of battens 23, which slide on guide bars 24. The intermediate leaf 26 is housed in cut-out parts of these bars 24. When the leaves 21, 22 are drawn out, the leaf 26 is raised by levers 28, Fig. 3, actuated by members 31, e.g. pins, on the undersides of the parts 23. The parts 21, 22 are connected by a lever 63 and links 65 so as to move inwards and outwards simultaneously. The parts being closed up are released by a trigger-operated catch 67, the parts 21, 22 are pulled apart and the leaf 26 is raised. During this movement, pins on the transverse edge of the leaf 26 move in the vertical parts 44, Fig. 6, of 7-shaped slots in brackets 45. When the leaf has reached its uppermost position, a hand lever 52 is moved so as to move the leaf 26 laterally ; the pins referred to then move laterally in the parts of slots and retain the leaf in its upraised position. The sections 21, 22 are then moved inwards until they meet the edges of the centre leaf 26.

Abstract: 1,058,745. Shaft couplings. R. GABBIONETA. Aug. 4, 1964 [Feb. 15, 1964], No. 31389/64. Heading F2U. [Also in Division F1] In a pump (see Divisior F1), an extension 32 of the rotor is surrounded by an acid-resistant, wear pre ventive sleeve 35 forced against an acid-resistant seal 6 by a nut 7. A gasket (not shown) is arranged be tween the nut 7 and sleeve 35. Preferably, the thread between the nut and ex- .tension is sealed by acid resistant plastics tape After removal of pump cover 17 the assembly of rotor 31, extension 32 sleeve 35 and nut 7 can be removed by unscrewing a nut 10 from the nut 7, the nut 10 seating against a fixed shoulder 23 and thereby forcing the assembly to the left. The extension 32 is keyed at 9 to the shaft 8 and at 34 to the sleeve 3.5. The nut 10 is locked to the shaft 8 by a screw. 13. The nuts 7, 10 are tightened in a direction contrary to the direction of rotation of the shaft 8. The pitch of the thread between nuts 7 and 10 is greater than that between nut 7 and extension 32. Thus during pump operation, the nut 7 cannot slacken on the extension 32 on account of different pitches and the abutment between the extension and a shoulder 12 on the shaft 8. Rings 14 and 15 are split to permit their removal and thereby access to the nuts 7, 10 and screw 13.
