REMo MARIAN! ATTORNEY United States Patent DISPENSER FOR MULTIPLE MARKER TAPES Remo Mariani, Berkeley Heights, N.J., assignor to The Thomas & Betts C0., Elizabeth, N.J., a corporation of New Jersey Filed Mar. 1, 1968, Ser. No. 709,550 Int. Cl. 1326f 3/02 U.S. Cl. 225-33 7 Claims ABSTRACT OF THE DISCLOSURE The dispenser is composed of a plurality of discrete modules which can be positioned with respect to one another by hermaphroditic coupling means and joined by a fastening means. Each module comprises one outer wall, a web hub, a tape guide and two cutting edges. The fastening means is removable so that individual modules may be removed or replaced. Alternate use of particular cutting edges permits close spacing of the modules.

BACKGROUND OF THE INVENTION Field of the invention The invention is directed to the field of dispensing selectable lengths of webs initially wound upon a central core. The invention finds particular utility in the field of dispensing marker tapes which comprise a first face upon which one or more indicia may be placed and a second face having a coating of a pressure sensitive adhesive. Such marker tapes may be dispensed in selectable lengths in accordance with the size of the cable to be marked or in accordance with the size of the other objects to be marked. Due to the necessity for a large member of available marking codes a dispenser capable of dispensing a large number of indicia bearing marker tapes is required. Although the device is described in terms of the dispensing of marker tape it is also suitable for the dispensing of any other type of tape material.

Description of the prior art Prior art devices of the type commonly found for the dispensing of pressure senstive adhesive backed tapes generally do not permit the use of a plurality of marking tapes at the same time. Well known individual dispensers for plastic type mending tapes, permit merely the dispensing of a single roll of such tape. Additionally, dispensers such as the type used to dispense laundry tape, or other water wettable adhesive backed tapes, or providing for semiautomatic metering also permit merely the use of a single type of tape. Dispenser for a plurality of tapes, are quite cumbersome and generally available in only bench type units. In such units a plurality of individual tape rolls are placed upon a central shaft. Spacers are placed between individual ones of the tape rolls and the tapes are then fed across a support. If it is desired to use any one, or all, of the tapes it is necessary that the desired length of tape be pulled from the dispenser and a portion, adjacent that to be cut, be adhered to the support. A razor blade, or other type of traveling knife edge, is then caused to traverse the support thereby severing any of the tapes which have been extended. A device of this type is both heavy and cumbersome and would not permit; for example, the marking of suspended cables due to the absence of nearby benches to support the dispenser.

SUMMARY OF THE INVENTION The invention overcomes the difficulties noted above with respect to prior art, multiple tape dispensing devices. It makes available a device which is simple, lightweight and which may be easily carried by the user to the marking location without regard as to whether it was at ground 3,502,252 Patented Mar. 24, 1970 ice level, above, or below it. No additional supports, such as a worktable, or the like, are required. Said device is a simple, lightweight device which may be easily hand held and may be operated to selectively present the desired marking tapes and which may be cut to desired selectable lengths in accordance with the needs of a particular marking job. In that the length of the tapes are selectable, as to a particular cable size, problems which usually accompany a metering type of dispenser are eliminated. Notably, a metering type of marking tape dispenser would provide approximately 1 /2 inches of tape. On a very small conductor to be marked, the 1 /2 inches of tape could result in the build-up of an unwanted shoulder at the point of marking. Such shoulders on a number of wires to be pulled through a conduit might very well prevent their being moved through the conduit and would definitely interfere with their operation.

The present dispenser provides a simple dispenser for a plurality of marking tapes by providing individual dispenser modules, each of which contains a single web of marking tape and which can provide not only for the support of the tape but also for the cutting thereof. Provision is made within each of the modules for the joining of a plurality of modules to build-up a dispenser. A fastening means is then passed through each of the dispenser modules in order to hold them together in a dispenser assembly. The fastening device may also include a ring or other attaching device whereby the dispenser may be readily carried on the belt of the user. By the unique technique of providing two cutting edges for each dispenser the tapes within the dispenser may be alternately arranged so that each odd numbered tape dispenser module will have its tape directed over the upper cutting edge while each even numbered dispenser module will have its tape directed over the lower cutting edge, thereby decreasing their required center to center spacing between successive dispenser modules. It is therefore an object of this invention to provide a simple, lightweight, and easy to use disperser for a multiplicity of marker tapes.

It is still another object of this invention to provide a dispenser composed of a plurality of individual dispenser modules, each of which provides support and locking means for a web of marker tape therein and which provides dual cutting edges.

It is still another object of this invention to provide an improved dispenser for a multiplicity of marking tapes which facilitates the assembly of individual dispenser modules with other similar dispenser modules into a dispenser assembly.

It is yet another object of this invention to provide a dispenser composed of a plurality of dispenser modules having a minimum of center to center spacing by the employment of alternative cutting edges provided on the dispenser modules.

It is yet another object of this invention to provide a dispenser composed of a plurality of dispenser modules which may be assembled together by a selective locking means which permits the removal and reinsertion of dispenser modules at will.

Other objects and features of the invention will be pointed out in the following description and claims and illustrated in the accompanying drawings, which disclose, by way of example, the principles of the invention, and the best mode which has been contemplated for carrying it out.

DESCRIPTION OF THE PREFERRED EMBODIMENT Tu'ning now to FIG. 1 there is shown a dispenser module constructed in accordance with the concepts of the invention. Module 10 has a back member 12 but no complementary front member. Coupled to the back member 12, on the inside surface thereof, and extending in a direction transverse to the plane of the back member 12 are a plurality of hub nibs 14. Certain of the hub nibs 14 have attached thereto, at their remoe ends, locking tabs 16 which are arranged to engage the outer surface of a core 18 of a web of marker tape 20 inserted thereon. The hub nibs 14 are spread, as by slots 22 therebetween, to permit the flexing of the individual ones of the hub nibs 14 to conform to the inside diameter of the core 18 of tape 20 placed upon the hub nibs 14. The relaxed position of the hub nibs 14 is slightly greater in diameter than the inside diameter of the core 18 and thus as the core is placed over the hub nibs 14 they will be forced to contract and thus will accommodate the core size. A central hub 24 also extends from the base member 12 in a direction transverse to the base member 12. The height of the central hub 24 is made approximately the same as the height of the individual hub nibs 14. An aperture 26 extends through the central hub 24 and through the base member 12 for the passing therethrough of. a fastening device to be described below with reference to FIGS. 2 and 3.

Extending about a portion of the base member 12 is a side wall 28. Attached at one end of the base member 12 are support

members

30 and 32. Coupled to the

support members

30 and 32 is a further support member 34 which further serves to define. with the side walls 28, a partial enclosure for the roll of tape 20 placed on the hub nibs 14. Between the support member 34 and the side walls 28 are provided

slots

36 and 38 to permit the web of tape 20 to be conducted from within the enclosed portion of the module 10 to the region of the

support members

30 and 32. Coupled at the other ends of

support members

30 and 32 is support member 40. having at its ends an upper cutting edge 42 and a lower cutting edge 44. Tape wound, in the manner shown in FIG. 1. will be conducted from within the dispenser 10 through the slot 36 over the support 30 and thence over the cutting edge 42, whereas an oppositely wound tape 20 will pass through the slot 38, past the support means 32 and thence pass over the cutting edge 44.

Coupled to the side wall 28 are extensions 46 provided with apertures 48 therethrough. Press fitted into selected ones of these apertures 48 are pins 50. Additionally. in the

support members

30 and 32 there are provided further apertures 52 which also selectively receive in a press fitted arrangement pins 54. Alternatively, pins and 54 may be formed as a part of the extensions 46 and the

support members

30 and 32. By arrangement of the

apertures

48 and 52 and the pins 50 and 54. a hermaphaditic coupling arrangement is provided whereby the individual modules 10 may be assembled into a dispenser assembly. The closed face of the dispenser module 10, closed by means of the base members 12, is known as the back face whereas the open exposed portion, through which the tape 20 is inserted, is called the front face. By means of the hermaphaditic coupling arrangement, the individual dispenser modules 10 may be joined in a front to front, front to back, or back to back arrangement,

which arrangement will be better understood with reference to FIG. 2.

Turning now to FIG. 2 there is shown a dispenser assembly 6t) constructed of individual dispenser modules 10. Individual dispenser modules 10, with the exception of the end module 1011, are assembled in a front to back relationship so that the back member 12, of each succeeding module 10, serves as a cover for the preceeding module 10 and thereby effectively seals the tape 20 between the back member 12 of its own module 10 and that of the next adjacent module 10. The end module 1012 is arranged however in a front to front relationship with module 100, whereby the back members 12 of the two adjacent dispenser modules 10a and 1% form a chamber for two tapes 20. If desired, all modules 10 may be assembled in a front to back relationship and an additional cover plate, having the general shape of back member 12, may be added at the end.

The first tape 20, indicated by the reference numbers 0 upon it (see FIG. 3) is caused to pass in a counterclockwise direction through the slot 38 (not visible in the fig.) and thence over the support member 32 and finally over the cutting edge 44. This same arrangement will be true of the tapes from each one of the odd numbered dispenser modules. That is, the tapes 20 with the indicia O, 2, 4, 6 and 8 will each pass under the dispenser module and will be engaged by cutting edges 44. Tapes from even numbered dispenser modules 10, that is those having the positions 2. 4 and each additional even position and bearing the indicia l, 3, 5, 7 and 9 are permitted to pass through these slots 36 in a clockwise direction over the support member 30 and engage the cutting edge 42. As a result of the alternative arrangement of the tapes a closer center to center distance, or spacing, is possible than would be achieved were all the tapes passed over the same cutting edge. The entire assembly will be held together by means of an elongated member 62 having at a first end thereof a ring 64 (see FIG. 3) which acts jointly as a stop for the elongated member 62 to prevent its being pulled through the stack of dispenser modules and also provides a ring for attachment to a workmans belt or similar device.

Turning now to FIG. 3 the details of the fastener for coupling together the individual dispenser modules 10 into a dispenser is shown. The elongated member 62 is shown to pass through each one of the dispenser modules 10. A locking head 66 is provided at one end thereof, may be slid upon the elongated member 62 to a position in contact with the assembled dispenser modules 60 to rigidly hold them in locked relationship. Lockable head 66 will engage the member 62 to provide the necessary locking and holding force. However, the lockable head 66 may be selectively unlocked to permit the head 66 to be removed from the elongated member 62 so that individual modules 10 may be added or subtracted as desired, or replaced, as the tape 20 therein is exhausted. Further, if the locking head 66 is a single direction locking device, the ring 64 may be removed first and the elongated member 62 removed from the dispenser assembly 60. Head 66 can then be removed from elongated member 62 and latter repositioned as desired. As is stated above, the ring 64, at the opposite end of the elongated member 62, provides both a stop to prevent the elongated member 62 from being pulled through the stack of dispenser modules 10 and also provides for ready attachment to the belt of a workman or other person doing the marking job or for other purposes. If desired, the elongated member 62 may be replaced by a bolt and wing nut arrangement or any similar fastening device.

While there have been shown and described and pointed out the fundamental novel features of the invention as applied to the preferred embodiment, it will be understood that various omissions and substitutions and changes in the form of and details of the device itlustrated and in its operation may be made by those skilled in the art, without departing from the spirit of the invention.
