Definitions

  • ABSTRACT A simplified hand-held, hand-operated, plastic tape embossing 2?
  • F 'i gz i9i g tool having a novel means for engaging the distal end of a coil f i g of tape disposed in a cartridge or magazine and for feeding the l I 0 care same to and through a tape embossing station, without the necessity of manually feeding such tape end through the nor- [56]
  • This invention pertains to an embossing tool and more particularly concerns a self-loading means for feeding a tape or strip of plastic embossing material from a supply cartridge to and through such tool.
  • the present invention is achieved in a hand-held, handoperated embossing tool by providing a mechanical linkage between a cartridge having strip material coiled therein and the trigger mechanism that effects the embossing operation so that the entire cartridge is retracted a precise distance away from the embossing unit station as the trigger is squeezed manually; and during such retraction of the cartridge the end portion of the strip material, which extends outwardly of the cartridge, is restrained by a one-way catch pawl from corresponding movement away from the embossing unit. In this manner a precise length of strip material is pulled or fed out of the cartridge. Release of the trigger will cause the cartridge to be pulled forward to its former position and in so doing the end portion of the strip material extending outwardly of the cartridge is moved forward on toward the embossing unit a precise amount.
  • the arrangement is such that when a new cartridge is placed in the tool, it is only necessary to have the free end of the tape coil extend outwardly from the cartridge. Then, by operation of the trigger, the tape end will automatically be engaged and advanced to the embossing station, without any manual feeding of such end into the tape drive means.
  • FIG. I is a side cutaway view of an embossing tool according to the present invention.
  • FIG. 2 is a partial view of the rear portion of the embossing tool of FIG. 1 showing details of the operation of the present invention in one position of the trigger mechanism.
  • FIG. 3 is a partial view of the rear portion of the embossing tool of FIG. 1 showing further details of the operation of the present invention in another position of the trigger mechanism.
  • FIG. 4 is an end view of the embossing tool of FIG. 1 looking in the direction of view lines 44 of FIG. 1.
  • the embossing tool 10 of the present invention includes a first or right-hand body portion I2, and a second or left-hand body portion 14.
  • Each of the body portions may be formed from a single piece of material such as: by casting or molding of metal or strong plastic material. The two body portions are then fitted together, as best shown in FIG. 4, to enclose the other mechanisms of the tool as will now be described.
  • each body portion is formed with a pin or stud receiving opening 16; each opening 16 faces or opens toward the other opening on the other body position. In FIG. 1 only the opening 16 associated with the right-hand body portion is shown.
  • each body portion is provided with a trigger receiving cutout as best shown in FIG. I by the dotted line or edge 18 which shows the edge of the trigger receiving cutout for the right-hand body portion 12.
  • the trigger member is thus pivotable about the openings 16 in the plane of the tool as shown by direction arrow 24.
  • Stop lugs 26 formed on the rearward end of each side of the trigger member 20 engage a corresponding stop member 28 provided in the inner portion of the body portions 12 and 14 near the rear of the trigger receiving cutouts for limiting the clockwise movement of the trigger member 20 (as viewed in FIG. 1).
  • An embossing die engaging lug 30 is provided on the upper portion of the trigger member so as to engage with selective ones of the plurality of character dies on a rotatable die wheel 32 when the trigger member is squeezed or fully operated in the counterclockwise direction (as viewed in FIG. 1).
  • the forward portion of the trigger member 20 is provided with a cutout at its lower or bottom portion as best shown in FIG. 1 by left-hand edge 34 of the trigger members cutout.
  • a tape or strip cutter lever 36 is disposed within the trigger members forward end and pivoted on the same axis as the pivot axis of trigger member 20.
  • a stop lug 40 at the extreme forward edge of the cutter lever engages with the extreme forward walls 42 of the body portions 12 and 14 to limit the clockwise movement (as viewed in FIG. 1) of the cutter lever.
  • a cutter bed or anvil 44 is formed on the upper forward end of the cutter lever 36 for movement into engagement with embossed strip material that may be disposed in a strip path directly beneath a pair of cutter knives 48 disposed on a mounting bracket 50 when the cutter lever is squeezed or manually actuated in the counterclockwise direction, as shown by direction arrow 52.
  • a spring mounting post 54 is formed on the inside of the right-hand body portion 12.
  • a trigger member and cutter lever biasing spring 56 is mounted on the post 54.
  • the rearward end of spring 56 bears against the top of a lug 58 on the trigger member 20 while the forward end of the spring 56 bears against the top of a lug 60 formed on the rearward end of the cutter lever 36.
  • the force or bias of the spring 56 is such as to releasably or yieldably bias both the trigger member 20 and cutter lever 36 in their clockwise direction (as viewed in FIG. 1). It can also be observed that the trigger member 20, and the cutter lever 36 are movable or pivotable independently of each other.
  • a mounting bracket 50 extending from the forward end of the body portions 12 and 14 to a position above the rearward end of the trigger member 20 is suitably fitted in appropriate receiving slots formed in the body portions.
  • a circular embossing disc 32 is mounted on the middle portion of the bracket 50. Details of the embossing disc and its cooperation with the lug 30 are not necessary to understanding the present invention and no further discussion is made of the disc here except to point out that embossing strip or tape material is fed in a path of travel between male and female dies of the disc as will be described below. Details of the structure and operation of the disc 32 may be found in any of the U.S. patents mentioned above.
  • the rearward end of the bracket 50 includes a downwardly projecting arm or section 62, the lower end of which is provided with a rearwardly projecting arm or platform 64.
  • a resilient pawl or embossing strip engaging member 66 is mounted on the upper surface of the arm 64 and slopes in the forward direction.
  • the extreme upper end of the pawl 66 is spaced beneath a strip bearing platform 68, formed by lateral protrusions provided on the body portions 12 and 14, by a distance just slightly greater than the thickness of the strip material 70 to be fed through the tool as described below.
  • the rearmost end of the body portions 12 and 14 defines a rearwardly directed opening 72 through which a strip material cartridge 74 may be inserted, the material being contained in the cartridge in coil form as best illustrated in FIG. 2 of the drawing.
  • a strip material cartridge 74 may be inserted, the material being contained in the cartridge in coil form as best illustrated in FIG. 2 of the drawing.
  • the cartridge 74 is preferably formed of plastic having opposed sidewalls 76, rear wall 78, a top wall 80 and a bottom wall 82.
  • the sidewalls are separable, such as by a hinge joint 84 permitting a coil of strip material to be placed therebetween about a central post 86 extending from one of the walls.
  • An opening 88 is provided in the other wall circumscribing the post.
  • a pair of horizontally spaced ribs 90 are provided on the exterior surface of each wall on both sides of the opening 88 for a purpose to be presently explained, and extending forwardly from the center of the cartridge is a bracket 92 whose forward distal end is provided with a pin 94, extending laterally outward from the plane of each Wall and lying along the longitudinal axis of the ribs. Subjacent the bracket 92 the cartridge has a curved opening 96 terminating at the bottom wall 82. Slotlike openings 98 are also provided in sidewalls 76 adjacent the rear wall for viewing the amount of strip material in the cartridge.
  • the top wall 80 of the cartridge is provided with a tangential extension 99 terminating a general vertical alignment with pin 94.
  • a tab element 100 extends forwardly and upwardly from bracket 92 and its upper end is positioned adjacent the lower surface of extension 98 in such a manner as to resiliently urge the emerging strip from the coil to be forced against the extension in a tangential disposition to the coil.
  • the angular relationship of the tab permits the strip to be withdrawn from the cartridge, but effectively prevents contramovement into the cartridge.
  • the opposed inner portions 12 and 14 are provided with horizontally extending rails I02 defining a channel 104 therebetwecn extending to the rear end of the tool.
  • the supply end of the embossing material may extend past tab 100 in underlying relation to the exterior 98 and terminate at the forward end of the latter.
  • the tab will permit pulling or withdrawal of the material so as to feed the same to the embossing station.
  • Extending rearwardly and upwardly from the lower end of cam slot 106 is a cam surface 108 normally positioned in the path of the pin 94 of the cartridge.
  • Insertion of the cartridge 74 into the rear opening 72 of the tool 10, as shown in FIG. 1, causes the pin 94 to bear against the cam surface 108, raising the trigger member and permitting further insertion of the cartridge into the tool.
  • Manual squeezing or operation of the trigger member 20 in a counterclockwise direction while still pushing inwardly on the cartridge 74, brings the lower open end of cam slots 106 into alignment with the cartridge pin 94, the pin entering the lower end of the cam slots as best shown in FIG. 3.
