Definitions

  • This invention is concerned with a ribbon spool and a cooperative device adapted to be attached to an inking ribbon, enabling the ribbon to be effectively anchored to the spool on which the ribbon is to be wound.
  • the invention may be advantageously employed in various types of printing machines, addressing machines, dating devices, etc., where the ink for the impression is supplied by an inked ribbon.
  • the general object of the invention is to provide a spool and ribbon head so mutually formed that the attachment of the ribbon to the spool may be effected very quickly and will be permanent so long as desired, even though the ribbon be entirely unwound, while such normal anchorage of the ribbon to the spool may be readily released whenever desired.
  • Another object is to enable the anchorage device automatically to prevent shifting of the ribbon lengthwise of the spool, whereby the necessity for flanges on the spool is avoided.
  • My invention provides an anchorage device enabling the ready attachment of ribbons to spools located in comparatively inaccessible or not entirely visible places.
  • I have illustrated the spool mounted in a comparatively confined space, which embodiment is hereinafter specifically described.
  • Fig. 1 is a plan partly broken the ribbon with the attaching head thereon in its normal anchoring position
  • Fig. 6 is a similar view partly broken away and showing the head in the position it occupies while being inserted into the spool
  • Figs. 7 and 8 are cross-sections of the spool illustrating the ribbon anchorage respectively in its initial and final positions as it is being inserted in the spool
  • Fig. 9 is a crosssection on a larger scale through the anchoring head when attached to the ribbon
  • Fig. 10 is a view of a modified'form of spool
  • Fig. 11 is a cross-section of the spool of Fig. 10 in a plane indicated by the line ll-ll on that figure
  • Fig. 12 is a perspective of the ribbon wound upon a discardable spool, ready for shipping.
  • my spool is shown as a cylindrical body Ill having formed therein a longitudinal cavity ll communicating with the cylindrical exterior by a longitudinal slot l2 and a lateral centrally located notch l3.
  • the longitudinal entrance slot I2 is bounded by cylindrical parts it and l5,of the spool, which make ledges over portion of the cavity ll.
  • a lip l6 formed by an extension of the overhanging ledge IS.
  • the base of the notch I3 is formed with 'an intermediate ridge, that is to say, immediately adjacent the longitudinal cavity H such base extends at right angles to the parallel sided walls of the cavity H, as shown at H, Fig. 7, and then beyond this the base is inclined as shown at l8.
  • the cavity II is shown as leading from one extreme end of the spool well toward the other end.
  • the spool described is adapted to be mounted on a coaxial shaft and suitably secured thereto, as'by a tapered transverse pin, indicated in broken lines at 2
  • the shaft 20 may have a knob 22 by which it can be readily turned.
  • the anchoring head of this invention Permanently attached to the end of the inking ribbon A is the anchoring head of this invention, which projects in each direction from the ribbon, after the manner of the top arms of the letter T.
  • this head comprises a sheet metal member B embracing and clamping a portion of the ribbon after the same has been looped around the fiat narrow metal bar C as shown in Figs. 6 and'9.
  • the member B comprises a longitudinal portion b having side flanges bl and b2 and having an intermediately located lateral tongue b3 extending from the body portion, the flange on that side being interrupted at the tongue.
  • This flanged or channel shaped member has its central region oifset from the plane of the extreme portions and the tongue b3 leads directly from this offset portion, as indicated in Figs. 5 and 6.
  • the internal bar C also has a correspondingly oifset central region.
  • the tongue b3 and the adjacent portion of the ribbon are grasped between the operators thumb and finger so that the attaching device lies parallel to the ribbon, and then the ribbon and head are passed through the slot l2 into the cavity II, as illustrated in Fig. 7.
  • the anchorage device When the anchorage device is within the cavity I I, the operator presses down on the tongue b3, bringing the anchorage into theposition shown in Fig. 8 in the spool.
  • the anchorage device now transverse of the ledges l4 and I5 against the inner face of such ledges, so that the ribbon is effectively anchored to the spool.
  • the lip I 6 of the spool directly opposite the transverse notch i3, acts as a fulcrum or guide for the head, enabling it to swing readily into the notch as soon as the operator presses down on the end of the tongue b3.
  • the tongue When the tongue is located in the lateral cavity it prevents any longitudinal shifting of the ribbon.
  • Figs. 10 and 11 which illustrate a spool slightly modified from that shown in the preceding figures, I have omitted the ledge ii of former figures and extended the wall of the cavity ll directly to the outer surface of the spool, thus making a wider slot l2a than shown, for instance, in Figs. 3 and 4.
  • the lip l6a is correspondingly longer than in Figs. 3 and 4.
  • This wider slot provides more room for the insertion of the ribbon head and relies on the lip iia to hold the anchorage device on that side, the head when the ribbon is attached lying on one side beneath the ledge i4 and on the other side beneath the lip Ilia, whereby it is held to the spool.
  • the tongue b3 of the head occupying the ofiset of the cavity prevents longitudinal shifting of the ribbon on the spool, as already described.
  • the spool It is convenient to manufacture the spool separate from the shaft 20, and separability enables the most satisfactory installation in the machine in which the spool is to be used.
  • the cavity ll clear to. the central bore for the shaft it is possible to make the spool in a more simple manner than if the cavity were machined from the cylindrical surface. If desired, I may make the spool as a die casting.
  • Figs. 1 and 2 I have illustrated my spool and attached ribbon mounted in an addressing machine.
  • the machine there shown comprises a bed 30 having a supporting portion 3! along which address plates, indicated at 32, may be fed beneath confining ledges 33 by suitable reciprocating racks 34. Extending across the region of such address plate is the inking ribbon A which on one side of the plate region passes across a turning plate of a bar 35 and thence passes directly to the spool ill to which the end is attached, as described.
  • the ribbon On the other side of the plate region the ribbon is shown as passing across a turning member 36 and thence wound upon a hollow sheet metal spool D which is clamped between two heads 40 and 4
  • the clamping head 40 is on a shaft 45 which carries a ratche wheel 46 in the same vertical plane as a ratchet wheel 26 on a spool shaft.
  • a ratchet driving mechanism indicated at 50 and which has a pair of ratchet pawls cooperating with the respective wheels and one or the other of them active at any time.
  • Such driving mechanism may be of the type shown, for instance, in Patent No. 997,- 615, granted to The American Multigraph Company, and in that case whenever the ribbon becomes entirely unwound from one spool to which it is still anchored its resistance causes the shifting of the drive mechanism so as to operate the other spool to feed the ribbon in the reverse direction.
  • the spool i0 is a permanent part of the machine.
  • the spool D is a hollow sheet metal member which may be sold with the ribbon wound upon, it.
  • Suitable plates 37 and 38 of the machine overlie the respective spools and are readily removable for installation or change of the ribbon.
  • the rod 42 is pulled out by means of its knurled head 44 against the action of the spring 43 and the spool placed between the heads 40 and 4
  • the ribbon is then passed about the turning bar 36 and over the region along which the plates are fed about a turning bar 35, and the head B on the free end is passed through the slot I! of the spool l0 and the attachment completed by pressing the tongue of the head into the lateral notch of the spool cavity.
  • the spool III is a permanent part of the machine formed to cooperate with the anchorage device, while the spool D is a light sheet metal member to which the end of the ribbon may be permanently attached in any manner, I provide a very ready method of marketing the ribbon.
  • the end thereof is attached in the factory to the sheet metal spool D, the head attached to the other end, and the ribbon wound up around the spool, as illustrated in Fig. 12.
  • the head lies closely against the ribbon and allows the ribbon to be put into a small container and sold in wound-up condition, ready for installation.
  • the freeing of the spool D by drawing out the rod 42 allows the sheet metal spool to be removed; then the anchorage is freed from the permanent spool l0 and the loose portion of the ribbon wound about the spool D, leaving the ribbon in convenient condition for return for reinking, if desired.
  • the hollow sheet metal spool D may be made in any convenient form and the ribbon permanently attached thereto, as desired. I find it very convenient, however, to employ the characteristics set out in Patent No. 1,727,882, granted to Addressograph Company, wherein the sheet wind up the ribbon onto that spool, the ribbon ed, a cavity within the body of the spool extend metal spool is a single sheet of metal bent into a suitable form with adjacent free edges which are turned inwardly and flanged to overlap each other within the spool. These free edges may be locked together by a longitudinally slitted small metal tube which is slid lengthwise of the spool over the inturned flanges and binds them together, as illustrated at E in Fig. 12.
