Definitions

  • ABSTRACT A device for winding undeveloped films on a developer coil, said device including (a) a spindle to which the [54] FILM g DEVICE FOR COILTYPE coil is attached for the winding operation; (b) a pivotally F g i secured guiding tongue for assisting in the insertion of the film 5 Chums rawmg into the coil and (c) a resilient strip affixed to said tongue and [52] U.S. Cl. 242/76 provided with a detent notch to temporarily interlockingly en- [5 I] Int. Cl B65h 27/00 gage said coil and thus immobilize said tongue with respect to [50] Field of Search... 242/77.l, said coil and to prevent said coil from axial displacement with 76 respect to said spindle.
  • This invention relates to a film-winding device for developer coils having spaced turns and supported by radially extending braces; said device generally includes a handle provided with a laterally offstanding spindle to which the developer coil may be attached. At one end of the handle there is pivotally secured a guiding tongue assisting in the insertion of the undeveloped film into the coil. Said tongue, when in its operative, inserting position, engages, with an abutting element, the end of the developer coil.
  • the abutting element on the guiding tongue associated with the coil-type film developer is formed as a resilient strip provided with a detent notch which cooperates with one of the radial braces supporting the developer spiral.
  • the strip with its detent notch may be brought into interlocking engagement with a brace of the coil by simple manipulation, thus immobilizing the guiding tongue in an operative position and also preventing the coil from slipping off the spindle.
  • the threading of the film may be performed without difficulty or delay.
  • FIG. 1 is a side elevational view of a preferred embodiment
  • FIG. 2 is a plan view of the same embodiment.
  • FIG. 3 is a perspective view of one part of the same embodiment at an enlarged scale.
  • the developer coil comprises two loosely wound wire spirals 4a and 4b, each having turns 5 and each being maintained in an axially spaced position by radially and axially extending braces 6, The terminus 7 of the spiral 4a is secured to one of the braces 6, while the terminus of the spiral 4b is bent outwardly to form a manually engageable lever 8.
  • one of the braces 6 holds on its axially extending portion, a clasp-shaped takeup member 9 having an integral detentspike 10 for holding the inserted film 11 (shown in phantom lines).
  • the film 11 is guided into the developer spiral 4 by means of a guiding tongue 12 which is pivotally secured to a shaft 13 affixed to flange 2.
  • a detent strip 14 formed of a flat resilient metallic or plastic material.
  • the strip 14 is twisted so that adjacent tongue 12, its plane is normal to the axis of spindle 3, while subsequently it extends parallel thereto.
  • the strip 14 is resilient in the transversal direction of inserting tongue 12.
  • the strip 14 On its lateral edge adjacent the handle 1 and in the vicinity of its free end remote from tongue 12, the strip 14 has a detent notch 15 in which nests in the operative position of the tongue 12, a circumferential portion of brace 6 attached to the spiral end 7.
  • detent notch 15 comprises a leading edge 17 slanting opposite the direction of eventual film winding operation, and a trailing edge 18 substantially normal to the axis of the terminal, radial portion of brace 6. The function of edges 17, 18 of detent notch 15 will become more apparent from the ensuing description of the operation of the embodiment.
  • the tongue 12 is turned upward about shaft 13 (counterclockwise as viewed in FIG. 1), until the free end of strip 14 engages the top face of the outside turn of spiral 4a.
  • the developer coil 4 is rotated clockwise as viewed in FIG. 1 by slowly cranking the lever 8.
  • Strip 14 is meanwhile held against spiral 4a as described in step 2.
  • the leading slanted edge 16 of strip 14 engages brace 6 immediately adjacent the spiral terminus 7 and, as coil 4 continues to rotate, the strip 14 is resiliently displaced towards spiral 4b in a direction substantially parallel to spindle 3.
  • detent notch 15 and said brace 6 arrive into alignment, at which instant notch 15 snaps into interlocking engagement with brace 6 immediately adjacent the spiral terminus 7. In this stage, illustrated in FIGS.
  • the tongue 12 is locked in an operative position ready to guide the film to be attached to spike 10, and the developer coil 4 is locked against axial displacement with respect to spindle 3. It is to be noted that after notch 15 snaps in place, further clockwise rotation of coil 4 is prevented by virtue of an abutting relationship between edge 18 of notch 15 and brace 6.
  • the device is held in one hand by handle 1, and, with the other hand, the film 11, the leading end portion of which is cut to have a tapered shape, is forwarded towards the spike 10 of takeup member 9 while guided by tongue 12.
  • the position of the film at this stage is indicated by phantom lines in FIG. 2.
  • tongue 12 be maintained in its operative, guiding position. In similar devices of the prior art this was achieved by continuously urging, with one finger of the hand holding the handle 1, the tongue'lZ into its proper position. According to the invention, however, not only is the tongue 12 securely locked in its operative position and thus no manual assistance for so maintaining it is necessary, but a highly undesireable axial slippage of coil 4 on spindle 3 is also effectively prevented without continuous manual assistance.
  • a sixth step subsequent to securing the film 11 to spike 10, the film winding operation is started by cranking the handle 8 to effect a counterclockwise (as viewed in FIG. 1) rotation of developer coil 4.
  • the brace 6 acting as a cam, rides up on slanting edge 17 of detent notch 15 displacing strip 14 towards spiral 4b in a direction parallel with the axis of spindle 3.
  • detent notch 15 and brace 6 become disengaged.
  • the film is wound by drawing it in between the spaces of the individual turns of coil 4.
  • the coil 4 with the film wound on it may be lifted off spindle 3, because strip 14, since the disengagement of notch from brace 6, no longer prevents an axial displacement of coil 4 on spindle 3.
  • a device for winding film on a developer coil formed of a pair of spaced, loosely wound spirals maintained in place by radially extending braces, said device being of the type that includes a spindle rotatably and removably holding said coil and a pivotally secured tongue for guiding said film into said coil,
  • detent means formed of a resilient strip secured at one end to said tongue and movable therewith, said strip including a detent notch to interlockingly engage a portion of one of said braces when said tongue is pivoted into an operative position, said tongue being immobilized with respect to said coil and said coil being prevented from displacement on said spindle by the interlocking engagement between said detent notch of said strip and said portion of said brace.
  • said detent notch has a leading edge slanting opposite the direction of rotation of said coil for winding said film, said detent notch further has a trailing edge extending substantially normal to said radial portion of said brace.
