IPC: G07D5/04
Filed: 1953-01-15
Abstract: 718,949. Coin-weight testing. ICE-MATIC, Ltd. Sept. 10, 1953 [Jan. 15, 1953], No. 1224/53. Class 27 A coin-weight testing mechanism for coin freed apparatus comprises a platform 11 pivoted on a fixed wall 4 and tilted by an adjustable weight 13 or spring to bridge the ends 10 of a gap in a ledge 6 forming a coin track at the bottom of a recess in a hinged clearing wall 5. A coin 7 of correct weight will depress the platform 11 sufficiently for the coin to clear a corner abutment 15 at the top of the recess and continue down the track to other testing devices or to the freeing mechanism. A light-weight coin will be arrested by the abutment 15 and an over-weight coin by the stepped-down end 10 of the gap, unless it is sufficiently heavy to depress the platform until the coin can fall through between the ends of the gap. Arrested coins are cleared by moving the clearing wall away from the fixed wall by means of a button depressed by the user or by operation of a drawer of the apparatus or, as shown in Fig 1, by means of delayedaction pendulum means which allows time for the coin test or tests. The clearing wall 5 is normally held away from the fixed wall 4 by a two-armed lever 16 engaging a pin 18 on the clearing wall but an inserted coin 7 bears on a roller 20 on a lever 19 and, as the lower part of the lever moves to the right in Fig. 1, the lever 16 is removed from below the pin 18. The return of the lever 19 to its normal position is delayed by escapement mechanism comprising a pendulum weight 24 pivoted at 25 and having two pawls 23 engaging an arcuate toothed portion 22 of the lever 19. On return of the lever to its normal position, an adjustable stud 27 lifts the weight 13 and thus lowers the platform 11 to clear any arrested coins. Specifications 425,024 and 471,644 are referred to.

Title: Improvements in or relating to typographical composing machines
IPC: B41B11/18
Filed: 1952-01-18
Abstract: 702,805. Type-bar-making machines. MERGENTHALER LINOTYPE CO. Jan. 18, 1952 [Feb. 1, 1951 No. 1478/52. Class 100 (3) Distributing matrices.-In a typographical composing machine such as known under the Registered Trade Mark "Linotype," of the kind wherein the matrices are distributed by a mechanism including rotatable screws for conveying the matrices along' a distributer bar, the screws being driven through a clutch which is adapted to be rendered inoperative by axial movement of one of the screws on overload due to jamming of the matrices, the clutch includes driving and driven members capable of axial separation for disconnecting the drive to the distribution screws, the axially-movable clutch member being adapted to be moved to the disconnected position by axial movement of the movable distributer screw on overload. Axial movement to the left, by the camming action of a jammed matrix, of the screw 1a causes swinging of one arm 20a, carrying a roller 22 of an inverted U-shaped member 20 pivoted on a shaft 21, whereby a knife-edge 23a on a plate 23 carried by the second arm 20b of the member 20 is withdrawn from its normal engagement with a plate 25c carried by one arm 25a of a second inverted U-shaped member pivoted on a shaft 26. Consequently, a disc 27 on the end of the second arm 25b of said second member is moved by the action of a compression spring 28 against a threaded sleeve 10. The sleeve 10 is secured to the driven member 8 of the distributer clutch, and since it is rotating, the roller 27 cams it to the right to open the clutch. The sleeve 10 carries a collar 31 which, on the rightward movement of the sleeve, acts against one of two rollers 29a to move a slide 29 to the right. The movement of the arm 25b causes a finger 33 thereon to release a pawl 32, which moves by spring action into a position to hold the slide 29 in its rightward position and thereby, through the other of the rollers 29a, to hold the clutch disengaged. The second U-shaped member has a handle 25f and by moving this to swing the roller 27 out of contact with the sleeve 10, a cam edge 25e on a portion of the plate 25c acts on a depending portion of the plate 23 to swing over the member 20, so that the roller 22 moves the screw la to its normal position. Movement of the handle also moves the pawl 32 out of engagement with the slide 29 to allow the clutch to close. Magazines-.-When a magazine entrance is in position to receive distributed matrices, a set screw 40 carried thereby acts on a lever 36 to hold an upstanding bevelled finger thereon out of contact with a set screw carried by the arm 20a. When no magazine entrance is in proper position, the action of the finger on the set screw cams the arm 20a to the left so as to open the clutch as described above.

Title: A control arrangement for an electro-magnetic clutch
IPC: F16D37/02
Filed: 1955-01-18
Abstract: 781,934. Automatic current control systems. ELEKTRO-MECHANIK GES. Jan. 18, 1955 [Jan. 23, 1954], No. 1509/55. Class 38 (4). The starting current of a motor, for driving a machine through an electro-magnetic clutch, is maintained constant by including a magnetic amplifier in circuit with the energizing supply for the clutch, the magnetic amplifier being controlled for varying the motor load, in accordance with deviations of the motor current from a desired value. A squirrel-cage motor 10 has its three-phase stator winding energized over a switch 27, and the A.C. windings 15, 16 of an auto-excited magnetic amplifier 14 are connected to the motor supply in series with a transformer 13 supplying a clutch winding 11 over a rectifier 12. The magnetic amplifier has oppositely-wound control windings 19, 20, the former being energized over a rectifier 22 from the output of a transformer 21 representing the motor current, and the latter being energized over a rectifier 23 from the constant output of a saturating transformer 24 representing a desired reference value; the latter value may be set by resistors 25, 26. A desired degree of clutch excitation is obtained by varying a tapping on the primary of transformer 13. In operation, with the motor current at the desired value, windings 19, 20 carry equal currents, the degree of saturation of the amplifier core being such as to allow the required excitation of winding 11 ; deviations of motor current result in unequal currents in the control windings, with a consequent change in core excitation to adjust the clutch excitation in a sense as to restore the motor current; the non-attainment of the desired value of the latter may be signalled by passing the control current through opposed windings of a relay, which is switched in during starting of the motor. In a modification, the clutch winding 11 may be supplied directly through slip-rings from the amplifier, in which case transformer 13 is omitted, and amplifier 14 is supplied from an A.C. source through an input auto-transformer with a variable tapping. The control is also stated to be applicable to a separately excited clutch.
