Definitions

  • a printed line usually consists of a succession of printing characters that can be set into the periphery of typewheels.
  • each wheel carries a set of printing characters on its periphery and the line of type can be set by hand by rotating the type-wheels into the individual positions in which they jointly give the desired line of print.
  • the typesetting takes place automatically, without necessitating any halts and possibly even without slowing down the printing rate.
  • the invention accordingly provides for associating to each type-wheel a rotary contact adapted to cooperate with fixed contacts equal in number to the number of printing characters carried by said wheel, means for rotating the type-wheel in synchronism with the associated rotary contact, means for locking the type-wheel in the position required for line composition, and selection means for energizing the fixed contact corresponding to the chosen character, whereby to cause closure of the electric circuit leading up to said fixed contact to rotate the type-wheel and associated rotary contact until the latter encounters the selected fixed contact, thereby locking the type-wheel in the printing position corresponding to the chosen character.
  • the rotary contact is carried by a wheel distinct from the type-wheel but is adapted to be driven in synchronism therewith.
  • the fixed contacts are dis osed over a circumference on a stationary plate adjacent the type-wheel carrying the rotary contact.
  • the locking means can include bars acting as engagement pegs and each adapted to be retracted against the countering force of a spring when a coil surrounding the bar is energized. Provision is made for two pegs acting simultaneously, one to lock the type-wheel and the other to lock the wheel carrying the rotary contact.
  • the type-wheel can comprise notches between successive print characters to receive the tip of the associated peg, while the wheel carrying the rotary contact can comprise peripheral notches which are spaced in identical fashion to the type-wheel notches.
  • the type-wheel and the wheel carrying the rotary contact can be combined into one.
  • the rotary contact can then be lodged in a recess in the ty e-wheel and cooperate with a fixed printed circuit which is connected to the selective system and disposed between two successive type-wheels.
  • Such an apparatus executed in accordance with this invention can be used separately for printing cheques, envelopes and the like, as well as documents which have already been printed and cut to size. it can also be used for continuous printing, in which case it is coupled to a continuously operating machine enabling the typeset to be changed automatically without requiring a halt and possibly also without slowin down the printing rate.
  • composition of a line can be changed automatically in this way by connecting the apparatus electrically to any convenient device whereby to set the line of type as required and also to determine the quantity of documents to be printed with a given composition and the order in which the composition is to be changed.
  • FIG. 1 is a schematic fragmentary sectional view of an apparatus according to the invention
  • FIG. 2 is a diagrammatic detail side elevation of the printing device
  • FIG. 3 is a schematic illustration of one embodiment of the invention.
  • FIG. 4 is a schematic illustration of an alternative embodiment of the invention.
  • FIG. 5 is an axial section taken through a type-wheel in the embodiment of FIG. 4;
  • FIG. 6 is a similar view to FIG. 3, showing a third possible embodiment of the invention.
  • the apparatus illustrated in FIG. 1 comprises a set of type-wheels 1, la, lb of identical diameter, bearing letterpress printing characters on their periphery.
  • Said type-wheels are removably mounted on a shaft 2 and adapted to be rotated by friction by shaft 2.
  • Said shaft 2 is supported on a casting 3.
  • the type-wheels as a whole can be translated under the action, for example, of a connecting-rod d of which one end 4a is revolved and the other end db which is rigid with the type-wheel shaft 2, slides in a stationary slideway 5 in the casting (see FIG. 2).
  • An inking device comprising parallel rollers 6, 6a, 6b, for instance, conveys ink from a reserve supply 7 onto the type face on the type-wheels.
  • Shaft 2 carries on its end a bevel pinion hi meshing with another pinion 11 mounted on a shaft E2 of variable length, which'shaft consists for instance of two telescopic sections (as illustrated) or two sections connected by a universal joint.
  • Said shaft 12 mounts on one extremity a pinion 13 which meshes with a pinion 14 on a shaft 15.
  • Shaft 15 supports a set of tracking wheels 16, 16a, 16b the number of which is equal to the number of type-wheels and which will be described in greater detail hereinafter.
  • the tracking wheels are mounted on shaft 15 in the same way as the type-wheels on shaft 2, i.e., they are removable and can be rotated by friction by shaft 15.
  • the tracking wheels can be mounted on a fixed casting.
  • the coupling between shafts 2. and i5 is such that the two shafts rotate in synchronism.
  • Shaft 15 likewise extends through a set of stationary wheels 1], 17a, 17b each of which is associated to a tracking wheel.
  • the system will comprise a set of tracking wheels separated by stationary wheels.
  • Shaft 15, and consequently shaft 2 is rotated by a motor 19, through a suitable reduction gear 213, 21.
  • Motor 19 can be an independent motor or be the very motor of the machine to which the apparatus is coupled.
  • each type-wheel 1 there correspond a tracking wheel 15 and a stationary wheel 17 or commutator, two associated wheels being susceptible of rotation at the same speed.
  • said contacts are radially-disposed and uniformly-spaced conductive elements on the periphery of stationary wheel 17.
  • Each fixed contact a, 25 is connected by a conductor 26a, 26b, to a corresponding terminal 27a, 27b, forming part of a selector system.
  • Said selector system could be provided in the form, say, of a mobile contact 28 driven by suitable means such as a scanning head on an electronic machine.
  • Wheel 15 which is rotatable by shaft 15, carries a rotary contact 39 so disposed as to be able to touch each of fixed contacts 25a, 25b,
  • said contact 30 can be pivotally mounted on a shaft 31.
  • Wheel 16 is also provided on its periphery with notches 32 corresponding to the notches 33 which are embodied on the periphery of type-wheel 1 between successive printing characters.
  • the tracking wheel is preferably of the same diameter as the type-wheel and the spacing between notches 32 will therefore be equal to the spacing between notches 33.
  • An electric circuit comprises an input terminal 34, a conductor 35, two terminals 35 and 37 adapted to be connected through a contact 33, and two coils 39 and 4% connected in parallel across a conductor 41 leading rom terminal 37 and a return conductor 42 leading up to output terminal Coils 3? and 4% respectively surround peglike bars 44 and 45 loaded by springs 46 and 47 respectively.
  • Peg 44 is so designed that its extremity be urged by spring 46 into engagement with one of the notches 32 on wheel 1* when coil 3) is not energized.
  • peg 45 is so designed that its extremity be urged by spring 47 into engagement with a corresponding notch 38 on wheel when coil is not energized.
  • a circuit 4 leads from conductor 35 to rotary contact 39.
  • This circuit includes a coil 4? surrounding a bar so joined to contact 33, while the fixed point 51 of moblic contact 23 of the selector system is mounted on conductor 42.
  • Mobile contact 28 forms a separate and distinct switching device between each of the contacts 27a, 2'71) (and thus commutator fixed contacts 25a, 25b, respectively) and fixed switching contact 51.
  • the selection system When it is desired to compose a line for printing a document of any sort such .as a cheque, envelopes, or the like, the selection system (a scanning head of an electronic machine, say) commands a change in typesetting. Since the selection system is not in itself part of the invention, it can differ from one manufacturer to another. It will be understood, therefore, that the description tbereof given hereinbefore was provided by way of example only and not of limitation.
  • the selection system consequently places the contact 28 of each selector in contact with the terminal 2'7 associated to the character which is to be printed by the type-wheel 1 associated to the system.
  • Wheel 26 rotates until the rotary contact 30 it bears touches the fixed contact 25b connected to the selected terminal 271). This causes current to flow through conductor 48, whereupon coil 49 is energized and contact between 36 and 37 is no longer etsablished by 3. As a result, coils 39 and are no longer energized and pegs 44 and 4-5 are thrust back by springs 46 and 47 and simultaneously engage with cor-responding notches of wheels 16 and 1, which are thus held immovable. Type-wheel 1 is thus in position to print the chosen character.
  • This operation takes place simultaneously for all the wheels 16 and 1.
  • total selection is eifected in a maximum time slightly less than that taken by the wheels to make one revolution.
  • the selection control can be simultaneously for all the characters composing a line. It can be given at any time while printing is underway, the
  • one line can be earmarked for ma netic readings, another line consisting of ordinary printing characters.
  • a tracking wheel such as 16 is necessary when printing a line of which the pitch, i.e., the width of a character plus the space separating it from an adjacent character, is small.
  • the tracking wheel and the type-wheel can be combined into one, as schematically illustrated in FIG. 4 and in FIG. 5.
  • typewheel 1 (forming part of a set of type-wheels mounted as in the embodiment of the previous figures) is relatively thick and likewise bears peripheral characters separated by regularly spaced notches 33'.
  • Said type-wheel 1 is mounted on shaft 2 and associated to a fixed plate 17 having thereon an electric printed circuit which is composed, on the one hand, of a set of fixed contacts 25 arranged along a circumference and connected by conductors 2 6 to the selection system terminals 27 and, on the other, of an endless terminal 52 which consist of a rim concentric with said circumference and connected to the conductor 48 in which coil 49 is mounted.
  • a rotary contact 3% which is rigid with wheel 1 and therefore rotatable therewith.
  • Contact 36' is so designed that one of its extremities touches endless circular terminal 52 and its other extremity can touch all the contacts 25 in succession.
  • FIGURE 6 represents a simplification of the first embodiment described hereinabove.
  • Tracking wheel 16a is part of the set of tracking wheels and embodies peripheral notches 32a cut into the form of gear cogs, and this likewise applies to the other tracking wheels.
  • Each type-wheel such as 1a is provided with an equal number of cog-like peripheral notches 32a of same module as the tracking wheel notches and meshing therewith.
  • the locking peg 44 which locks the tracking wheel also locks the type-wheel associated thereto.
