  • This invention relates to apparatus for retaining a machinemember in an active position thereof.
  • actuatmg means to en- .gage and positively to move said member from the inactive to the active position thereof, a solenoid the pole of which is engaged by said member in its active position, circuit means to energise said solenoid thereby to retain said member in its active position, and a restoring ele- 'ment to restore said member to the inactive position thereof on non-energisation of the solenoid.
  • a self-aligning arma- In a preture is carried by the machine member for engagement with the pole of the solenoid.
  • each actuating means may comprise a pivoted plate, an abutment carried by the plate to engage the code bar appropriate thereto, and a spring connecting the plate to said operating member to effect pivotal movement of the plate on actuation of the operating member thereby through said abutment to effect movement of the code bar from the inactive to the active position thereof.
  • Actuation of the operating member may be effected by a cam and linkage connecting the cam with the operating member, thereby to effect movement of the operating member to a position beyond that at which the springs have completed rocking of said plates to move the code bars into co-operation with their solenoids and so ensure proper ,co-operation between the code bars and solenoids.

  • Fig. 2 is a view of the rear of the unit shown in Fig. 1
  • Fig. 3 is a section on line III-III, Fig. 1,
  • Fig. 4 is a view of a part of Fig. 3 showing some of the parts thereof in different positions
  • Fig. 5 is an end elevation of the upper part of the apparatus shown in Figs. 3 and 4, and
  • Fig. 6 is a circuit diagram illustrating the manner inwhich the solenoids employed in the de-coding unit receive impulses to energise the solenoids.
  • the de-coding unit comprises five bars 10, Fig. 1, supported by fixed upright y provided as being indicative of data otherthan a digit in its active position.
  • Fig. 1 the code bars 1-2-8 are shown in the normal, inactive, positions thereof and the code bar 4 is" shown Movement of the bars 10 from the inactive to active positions thereof is effectedsimultaneousiy by actuating means shown in Fig. l as triangular plates 15, a plate 15 being'provided for each bar 10 and pivoted at 16 to a fixed frame plate 17. Movement of the plate 15 about the pivot 16 is simult-aneous'under the control of an operating member 18 supported for vertical sliding movement in brackets 19; Each plate" 15 is connected to the operating member 18 by 'a spring 20 which, when the operating member 18 is permitted to move downwards, as viewed in Fig.
  • a spring anchor pin 24 secured thereto rests against a shoulder 25 on the operating member 18 and downward movement of'the operating member is effected by a rocking plate 26 which co-operates with a projection 27 on the operating member and is pivoted about the axis of a pivot pin 28.
  • the rocking plate 26 is connected with a link 29 supporting a cam roller 30 co-operating with a cam 31 secured to a shaft 32 driven by means, not shown, from'the main drive of the machine to which the unit is attached.
  • the cam 31 is so constructed that when it is operated to move the operating member 18 downwards, against the action of a spring 33 connected thereto, it moves the operating member downwards until there is a clearance between the spring anchor pins 24 and plates 15- and the shoulders 25 on the operating member. 'By this means it is ensured that the abutments 21 on the plates 15 have each moved their bar 10 into positive engagement with the pole of the solenoid 23 which co-operates therewith.
  • each bar 10 has connected thereto an armature34, the armature being so connected to the bars as to beselfaligned with respect to the pole of the solenoid 23 when it is moved into engagement therewith.
  • the armature 34 is supported on a split pin 35 to be freely movable on the pin, and the pin itself is located in a slot, not shown, formed in the bar to facilitate free-movement of the armature and ensure the self-aligning movements thereof.
  • To the head of the split pin 35 is connected one end of a spring 36, the other end of the spring being anchored to the fixed upright member 11.
  • the spring 36 acts as a restoring element to restore'the bar to the inactive position thereof in the event that,'on presentation of the bar to the solenoid co-operating therewith, the solenoid is not energised or, alternatively, when the solenoid is energised to permit return of the bar to the inactive position thereof on de-energisation of the solenoid.
  • Fig. 6 illustrates diagrammatically a circuit whereby energisation of a solenoid 23 is effected, it being understood that a similar circuit if provided for eachof the solenoids.
  • R represents a part of a register in which the result of a multiplication operation performed by the calculating apparatus for the machine is set up and a reading-out operation is controlled by a read-out switch RO which is cam-operated from the main shaft, not shown, of the machine.
  • a read-out switch RO which is cam-operated from the main shaft, not shown, of the machine.
  • the pulse along line L from register R is, however, of short duration and accordingly, to ensure that the solenoid 23 remains energised for the required interval of time, there is provided a hold-on switch which is also cam-operated from the main shaft of the machine.
  • a hold-on switch which is also cam-operated from the main shaft of the machine.
  • testing members 14 After selection of the bars 10 has been effected by the solenoids 23, the testing members 14 are moved downwards to perform the testing operation. Prior to the testing operation the testing members 14 are retained in the inactive positions thereof by a restoring bar 37 secured to an actuating plate 38, Fig. 2, for movement therewith.
  • the testing members 14 are each provided with a pin 39, Fig. 4, which is engaged by the top of the restoring bar 37 during the restoring action thereof.
  • Movement of the actuating plate 38 is effected by a bell crank 40, Figs. 1 and 2, pivoted at 41 to the fixed frame plate 17, the bell crank 40 carrying a roller 42 which is engaged by a slide 43, Fig. l, to which is connected a link 44, the link being also connected to a rocking arm 45 secured to a pivot pin 46 to which pin is also secured an arm 47 carrying a roller 48 co-operating wtih a cam 49 on shaft 32.
  • Movement of the slide 43 to the right, as viewed in Fig. 1 rocks the bell crank 40 thus moving downwards the actuating plate 38 so that the restoring bar secured thereto is also moved downwards and the testing members 14 tend to follow the movement of the plate 38 due to the action of springs 50, Fig. 2.
  • the pins 13 on testing member 14 encounter a free passage provided by slots in the bars 10, as indicated by the pins 13 on the restoring bar 14a, Fig. l, the pins 13 will be arrested by the upper edges of the bars 10.
  • Each testing element 14 is provided with an abutment 51, Figs. 3, 4 and 5, and as can be seen from Fig. 3, the abutments 51 on elements 14 which have been arrested by the upper edges of bars 10 will be disposed in a position above that of an abutment 51 on an element such as 14a which has been moved by its spring 50 into a free path defined by slots in the bars 10.
  • the springs 50 do not, however, operate to move the element 14 to its full downward extent, this being effected positively by a plate 52 pivoted on a spindle 53 and sprung inwards towards the testing elements 14 by a spring 54, Fig. 2.
  • the spindle 53 is movable in vertical slots 55 formed in stop plates 56 carried by the plate 38 and is urged against the lower edges of stop plates 156 by springs 57, Figs. 1 and 5.
  • the spindle 53 is moved downwards by the plate and adjustable stops 58 ensure that the plate 52 is not disengaged gom3driving engagement with abutments 51 as shown in
  • adjustable steps 59, Figs. 1 and 5 which ensure that when the plates are fully restored the spindle 53 supports plate 52 in the position shown in Fig.
  • a decoding unit comprising a plurality of code bars supported for movement to and from inactive position thereof, testing members co-operating with and movable relative to said code bars to effect decoding according to the arrangement of code bars retained in the active positions thereof, actuating means for each code bar to effect movement thereof from the inactive to the active position thereof, a solenoid for each said code bar and having a pole to co-operate with the bar when the bar is in its active position, circuit means to energise said solenoids to retain in active position the code bars co-operating therewith, a restoring element for each said code bar to restore it to the inactive position thereof on non-energisation of the solenoid co-operating therewith, and an operating member common to all said actuating means to effect simultaneous movement of all said code bars from the inactive to the active positions thereof.
