Definitions

  • ABSTRACT Carrier for type carriers on a type cylinder for a type printing machine as for example a telex or teletype printing machine.
  • the type carriers are biased against the peripheral face of the cylinder by an elastic belt or band, accommodating radial outward movement of the type carriers to make a printing impression and then returning the type carriers to their rest positions after a printing operation.
  • the elastic band may be formed from an elastic belt made from rubber, an elastomer or a like material, which may extend through apertured portions of the type carriers to retain the type carriers to the type cylinder.
  • the belt may also be in the form of a relatively wide flat band having uniformly spaced apertures extending therethrough, and forming a means to accommodate buttoning of the type carriers to the band.
  • the present invention is directed to a high'speed teletype printing device and more particularly to a device for supporting the type carriers on a type cylinder and returning the type carriers to their rest positions after making a printing impression, in'which the support and return means for the type carriers is in the form of an endless elastic band or belt.
  • a principal object of the present invention is to provide a simple and efficient support for the type carriers of a high speed printing device on a type cylinder, arranged to effect high speed printing with a minimum amount of wear on the type carriers and support means therefor.
  • Another object of the invention is to provide a support for the type carriers on a printing cylinder in the form of a continuous elastic member so constructed as to reduce wear between the type carriers and support means therefor.
  • Still another object of the invention is to provide a support for the type carriers on the printing cylinder of a high speed teletype printing machine, utilizing an endless belt or band made from an elastic material supporting and accommodating the type carriers to make a printing impression and returning the type carriers to their rest positions.
  • FIG. 1 is a transverse sectional view of a type cylinder and support means for the type carriers on the type cylinder constructed in accordance with the principles of the present invention.
  • FIG. 2 is a fragmentary sectional view taken substantially along line Il-'II of FIG. 1, and drawn to an enlarged scale.
  • FIG. 3 is a fragmentary detail view taken through a portion of the type cylinder and illustrating the elastic support for the type carriers in elevation.
  • FIG. 4 is an enlarged transverse sectional view taken through a type cylinder similar to the cylinder shown in FIG. 1, and illustrating a modified form in which the invention may be embodied.
  • FIG. 5 is an enlarged vertical sectional view of a portion of the type cylinder taken substantially along line V-V of FIG. 4 and illustrating the elastic band retaining the type carriers to the type cylinder;
  • FIG. 6 is an enlarged detail view of a portion of a modified form of belt for retaining the type carriers to the type cylinder.
  • a type cylinder 1 is mounted for rotation about and for axial adjustable movement along a stationary support cylinder la, to bring selected type carriers into printing positions.
  • a suitable means is provided for rotatably driving and axially moving the type cylinder 1 along the support la, which need not herein be shown or described since it forms no part of the present invention.
  • the support cylinder la extends along and is mounted on a support 1b, shown as being generally C- shaped in cross section and as having an open portion facing a type hammer 1c, and accommodating a toggle lever 2 to actuate said hammer to strike a type carrier 3, to effect a printing impression.
  • An inked ribbon 5 is diagrammatically shown as being placed between the type carrier 3 and a sheet of paper 6 on a printing roll 4.
  • the type hammer 1c is slidably guided in the support cylinder la for radial movement relative thereto, to strikingly engage a frusto-conical inner end portion 3a of the type carrier 3, to effect a printing impression in accordance with a type signal.
  • the toggle lever 2, hammer 1c and means for operating said toggle lever and hammer form no part of the present invention so need not herein be shown or described further.
  • the type cylinder 1 is of an open annular construction and includes an outer annular rim 21 and a plurality of spaced annular partitions 22 spaced apart by dividers 23 to form type carrier receptacles.
  • the dividers 23 are shown as being generally wedge-shape in form and extending in generally radial directions and converging toward the cylindrical support 1a to provide type carrier receptacles diverging from the periphery of the type cylinder for the frusto-conical inner ends 3a of the type DESCRIPTION carriers 3, and to accommodate the hammer lc to strike a type carrier to make a printing impression.
  • the dividers 23 are shown in FIGS. 2 and 3 as each having an outwardly opening generally circumferentially extending slot 9 formed therein, for receiving an elastic belt 7, supporting the type carriers.
  • the elastic belt 7 is shown in FIGS. 2 and 3 as being of a round cross section, but need not necessarily be a round belt.
  • the belt extends through elongated apertures 25 extending through the frusto-conical inner end portion 3a of each type carrier 3 and supports said type carriers on the type cylinder 1, for radial movement outwardly of the periphery thereof to effect a printing impression.
  • each type carrier 3 has a head portion 36 biased into engagement with the periphery of the type cylinder by the elastic belt 7.
  • the elastic belt 7 may be made from a weldable or vulcanizable material which may be rubber or one of the well-known substitutes for rubber, such as a plastic material of the polyurethane elastomer type.
  • the type carriers are strung on the belt before vulcanized to a closed form.
  • the adjacent ends of belt may then be vulcanized or otherwise fastened together to form a loop.
  • the belt with the type carriers thereon may then be stretched over the type cylinder into the slots 9, with the type carriers positioned between the spacers 23.
  • the belt 7 thus biases the type carriers into engagement with the peripheral surface of the type cylinder 1 and accommodates the hammer to strike the reduced end portion 3a of the type carrier to effect a printing impression on the paper 6, and then returns the type carrier to the surface of the type cylinder into a rest position, with little, if any, frictional resistance or wear.
  • FIGS. 4,5 and 6 illustrate a modified form of the invention, in which the belt 7 is replaced by a flat relatively wide band 17, which may be made from an elastic vulcanizable-material such as rubber, or from a polyurethane elastomer or any other well-known substitute for rubber.
  • a flat relatively wide band 17 which may be made from an elastic vulcanizable-material such as rubber, or from a polyurethane elastomer or any other well-known substitute for rubber.
  • the flat band 17 is recessed in the surface of the type cylinder between an end radial flange 21 thereof, and a projection 30 extending from a divider 40.
  • the projections 30 are spaced along the dividers 40 to afford recesses for other bands 17 spaced along the face of the type cylinder, and to retain said bands in position on said cylinder.
  • Each band 17 has a series of rectangular openings 17a therein and spaced along the band equal distances apart and affording a means to accommodate buttoning the type carriers to the band.
  • a larger diameter radial flange Be is spaced outwardly of the radial flange 13d, to form an outwardly opening annular recess 13a of substantially the thickness of the band 17.
  • the type carriers 13 are buttoned to the band 17 by first inserting the frusto-conical end 130 of the type carrier into an aperture 17a of the band and then stretching the band and enlarging the aperture to accommodate the band to be slipped over the flange 13d and into the annular recess 13a, between the flanges 13d and 13e. As the type carrier is buttoned to the band 17, the cross sectional area of the aperture 17a will be increased by an amount generally indicated by the dashed line of FIG. 6.
  • the band 17 thus effectively supports the type carriers on the type cylinder and accommodates the hammers to strike the reduced diameter ends of the frustoconical projections of the type carriers to effect a printing impression, and resiliently holds the type carriers to immediately return the type carriers to rest positions, as soon as a printing impression has been made, and materially reduces friction and wear on the type carrier supporting parts therefor.
  • a plurality of type carriers carried by said cylinder and having head portions abutting the periphery of said cylinder and frusto-conical inner end portions extending within said cylinder and mounted for movement radially of said cylinder;
  • an endless elastic band made from a weldable heatsealable plastic material of the group of polyurethane elastomers extending through inner end portion of said type carriers and mountin said ype earners on said printing cylinder Wl' the head portions thereof abutting said cylinder, to be projected beyond the periphery of said cylinder to effect a printing impression, and retractably moving said type carriers to engage said head portions with the periphery of said cylinder as a printing impression has been made;
  • each type carrier has an apertured portion extending therethrough, larger in a radial direction than said elastic band and extending generally circumferentially of said cylinder in inwardly spaced relation with respect to the periphery thereof;
  • said cylinder having an opening leading therethrough registering with a receptacle as it passes thereby and accommodating the printing hammer to strike a converging end portion of a type carrier and to effect a printing impression.
