Patent GB-460864-A (GB)
Abstract: 460,864. Workmen's time recorders. STROMBERG ELECTRIC CO. June 4,1935, No. 1711/36. Convention date, July 12, 1934. Divided out of 460,845. [Class 106 (iv)] In a workmen's time recorder, the operating member controlling the time-printing mechanism is located adjacent the mouth of the card holder so that it may be actuated by the hand inserting the card. The operating member is in the form of a push bar 181a, Fig. 5, placed at the rear of the card-holder aperture 7 and connected by links 181c to levers 181f pivoted at 181g and having projections 181h, which engage a bail 181k connected to a lever 181b on which is pivoted a pawl 68 engaging the hammer 61. The hammer is thus rocked clockwise about its pivot 62 and turns with it a lever 74 about the same pivot against the action of a spring 73, the hammer contacting with a projection 76 of the lever 74. When the bottom of the hammer escapes from the pawl 68 the spring 73 turns the lever 74 and the hammer 61 anticlockwise until a projection 78 on the lever 74 is arrested bv a fixed member. The hammer 61 continues to move to make the impression, stressing the spring 75 which afterwards restores the hammer to its normal position. In a modification, Fig.'20, a lover 64 carrying the pawl 68 is rocked by the vertical depression of a bar 171 connected to the lever by a link 174 and bell-crank 176. The invention is shown embodied in a time recorder fully described in Specification 460,845. The Specification as open to inspection under Sect. 91 describes also a time recorder in which the operating member is situated in the front of the casing, towards the bottom thereof. This subject-matter does not appear in the Specification as accepted, but is described in Specifications 460,845 and 460,863.

[Also in Division F2] In a braking unit adapted to be secured to the bogie of a railway vehicle, a pair of brake beams 35, 40 are disposed on opposite sides of a bolster 15 which is mounted on springs 16 for vertical movement relative to the side frames 13, 14 of the bogie and brake beam operating means includes a beam operating lever 28 extending upwardly from one of the brake beams 40 at an angle to the vertical to be in operative connection with a horizontally mounted force multiplying lever means 26 operated by the piston means of a brake actuating cylinder 20. The brake actuating cylinder 20 and the force multiplying lever 26 are mounted on the bolster 15 for vertical movement with the latter such that the intersecting contact point 55 between the beam operating lever 28 and the force multiplying lever 26 is varied with movement of the bolster such that any change in the loading of the railway vehicle changes the multiplying effect of the force multiplying lever 26 so that the amount of braking force applied to the force multiplying lever 26 to the brake beam operating lever 28 increases as the weight of the railway vehicle increases, and decreases as the weight of the railway vehicle decreases. The brake beam operating lever 28 acts as a live lever and is interconnected by means of a horizontal rod 30 with a dead lever 32 the upper end of which abuts against a lug 44 formed on a slack adjuster 45 associated with the brake actuating cylinder 20. The position of the lug 44 on the slack adjuster 45 may be adjusted manually by rotation of an exterior handle 80 attached to a threaded shaft 82 or alternatively, the adjuster lug 44 may be automatically adjusted when the stroke of the brake actuating piston exceeds a predetermined amount. Provision is made for the attachment of a hand brake pull rod 150 to the pin 50 associated with the end 25 of the piston-rod 22, so that the pull rod 150 actuates the force multiplying level 26.

To maintain the spacing between separate biasing and recording heads 11, 10, Fig. 1c, constant, as the heads, particularly the recording head 10, wear, the biasing head 11 has arranged, over its working surface, a strip 19, Fig. 6, of wear-resistant material such as nylon or other plastics retained by pressure plates 20a, 20b and screws 21. The strip is slightly narrower than the tape 12, Fig. 7, so that as the tape wears a groove 68 into the record head 10, the strip can follow the wear and maintain the gap-spacing constant. The strip is resiliently biased against the tape by spring means (not shown) and acts as a tape pressure pad against the record head.

Abstract: 1443485 Cleaving meat carcases, removing teeth therefrom STATHMOS AB 5 Nov 1974 [8 Nov 1973] 47859/74 Heading A2U  A method of treating an animal carcase comprises (a) cutting open the carcase, (b) removing the offal, (c) pulling the carcase, lying on its back, through a cleaving station where it i's sawn centrally through the spine into two halves, (d) separating the two halves, (e) simultaneously tipping the upper part of each half inwardly and the lower part outwardly thereby forcing the spine portion to project and (f) sawing the spine portion from each half. In a suitable apparatus-Fig. 1-a carcase suspended by its hind legs from an overhead conveyor 15 engages at its lower end a trolley 13 and is tipped on to its back by advancement of the conveyor. Rails 20-25 ensure that the carcase arrives on its back on table 11 in correct alignment. The carcase is sawn in half by circular saw 30 and the two halves separated and suitably aligned by two ploughshareshaped members 34 and 35. Two circular saws 31 mounted on arms 32 can be swung upward from an inoperative position below table 11 to. cleave the spine portion from each half. On leaving the apparatus, the two halves are pulled back to a vertical position on the conveyor. If the carcase is to be cleaved with its head on, the front and canine teeth must first be removed using the apparatus shown in Fig. 8. Rocking carriage 50 is biased downwards on the lift by weight 53. When the suspended carcase contacts the carriage, it will be tilted towards the horizontal and the nose of the carcase will contact fixed cutting member 60 which will cooperate with sliding cutting member 59 to remove the teeth.

A device for drawing curtains includes a motor 14 driving a pulley 25 around which the bight of a drawcord is passed and includes a limit switch 20 which is actuated to stop the motor 14 by movement of a resiliently mounted member on which the pulley 25 is mounted when the tension in the cord increases at the end of the curtain travel. As shown in Fig. 2, the pulley 25 is carried on the motor shaft 24 on one side of a rocker plate 13 carried by the motor 14 which is hinged 16-18 to a fixed rectangular yoke 12. The cord passes upwardly from the pulley 25 and passes over guide rollers to extend horizontally along the curtain run. The rocker 13 is adjustably biased by a spring 21 to a position to tension the cord. When cord tension increases at the end of the curtain travel the rocker 13 hinges to engage the switch actuator 19 to stop the motor 14.
