Schriever and Sigmund Cheslin, both of 16333 Harper Ave., Detroit, Mich. 48224 Filed Oct. 21, 1966, Ser. No. 588,534 Int. Cl. 1332b; B41m US. Cl. 156-384 4 Claims ABSTRACT OF THE DISCLOSURE At the outset it will be understood that wire identification in and of itself is not new, since wire has been color coded, printed, tagged with printed cards and secured by hand, as well as having pre-printed adhesive labels applied thereto which are similar to those used in the modern store for afiixing the price of the merchandise, for many years. However, in todays modern age of mass production, the above mentioned methods are obsolete, because of the high cost of labor and the inability to maintain production at a high rate when these methods are used.

In view of problems which are encountered when using the above described methods of wire identification, the present invention was born. With the use of the present invention, wire identification means are applied quickly and neatly, at but a fraction of the cost of the other known methods.

It is therefore a primary object of the present invention to provide a new method and apparatus for the application of wire identification means wherein a unitary portable tool is used by non-skilled labor.

Another object of the invention is the provision of unitary hand tool which is semi-automatic in operation and adjustable to apply the desired indicia.

Still another object of the invention is the provision of appropriate indicia in said unitary hand tool, so that the wires in any circuit can be appropriately numbered in accordance with the numbers on the circuit diagram, thus eliminating the confusion which exists when a circuit must be re-numbered in accordance with available tags or labels.

Another object is the provision of a partable hand tool wherein the indicia can be incorporated on one or both sides of adhesive tag applied to a given wire.

Still another object of the present invention is the provision of a hand tool wherein the indicia can be changed in a minimum of time.

Yet still another object of the invention is the provision of a unitary hand tool for making pre-selected indicia tags wherein each and every tag is of the same uniform size.

The above and other objects of the present invention can be accomplished by the provision of a unitary portable hand tool assembly having a two part housing of generally symmetrical configuration and held together by a pivot pin positioned therebetween; fixed means integral with said housing for the support of a roll of tape, said tape having an adhesive applied to the edges of one surface of said tape; a tape feeder bar guided and supported by said housing members and located between each roll of tape; a indicia marking cartrage positioned in each of said housings adjacent said tape feeder bar; a cutter member carried by said indicia marking cartrage and cooperable with the end of said tape feeder bar, the end portion of said tape feeder bar being supported between two rollers,

a We one carried by each of said indicia cartrage marking members; adjustment means provided for said tape feeder member intermediate said pivot pin and said rollers for adjusting the length of said tape feeder bar so as to assure proper cut-off of said tape; the outer surface of each of said rollers is convex, while the surfaces of said feeder bar are concave, thus imparting a curve to each piece of tape thereby rendering same stiff during its displacement between the indicia marking cartrages, to avoid attachment of the tape to the tape feeder bar, the tape feeder bar is of less dimension than the space between the adhesive located thereon; pivotal displacement of the housing members toward each other acting to operate the cutoff means, apply the indicia and thereafter join the adhesive portions thereof together and around the wire located between two anvils located within said cartrages.

Other objects of this invention will appear in the following description and appended claims, reference being had to the accompanying drawings wherein like reference characters designate corresponding parts in the several views.

FIG. 11 illustrates the adhesive tape used.

FIG. 12 shows a finished tag applied to a wire.

Looking now at the drawings, FIG. 1 illustrates a simple version of the present invention. The complete assembly is identified by the numeral 10, with the outer housing 12 being disposed around the U-shaped inner housing. The U-shaped inner housing is shown at 14 and is adapted to an axle shaft 18 on which are rotatably mounted three indicia marking members 22. The axle shaft 18 extends through two slots 16 in the outer housing 12, while being disposed through two round openings R in the inner housing. Each of the slots 16 has located therein a compression spring 24 which is located in a spring pocket. The feet 26 of the outer housing 12 each have a groove 28 located therein for receiving a wire W. This then guides the wire W to the proper position beneath the idicia marking members. Each of the indicia marking members 22 are made from an absorbent material, which will retain ink or other marking medium in the manner of a sponge. Although each of the marking members 22 is shown with indicia thereon in the form of letters and numerals, the characters are optional and in actual practice would be reversed so that the character will print properly.

In actual practice, the wire W is positioned on a surface beneath the body of the assembly 10, within the grooves 28. The top section of the inner housing 14 is compressed against the springs 24, bringing the indicia marking members in contact with the wire, so as to imprint same. Since the marking members are resilient, they will conform to the wire configuration during the printing operation. The printing being completed, the springs 24 return the inner housing 14 to the open position so that the wire may be advanced and the cycle completed again.

While the above description has been directed to resilient marking members 22, the invention is not limited to such a construction, since the indicia marking members may be made from rigid, non-absorbing material. When this type structure is used, the indicia marking members are electrically or otherwise heated and the wire is branded with the desired character or characters. This structure is not illustrated.

FIG. 2. of the drawings illustrates an elevational view of the complete, unitary hand tool which is used to apply printed tags on a Wire. This assembly is identified by the numeral -40 and is made up of a two part housing 42, with each of the housing parts being of generally symmetrical configuration. It will be noted that the upper housing is identified by the numeral 42U, while the lower housing section is identified by numeral 42L. The two

housing sections

42U and 42L are joined by a pivot pin 44, which permits the housing members to be displaced with respect to each other. For purposes of description, only the upper half of the housing 42U and its respective components will be described, since it is readily apparent that each section is of similar construction. However, it will be understood that housing section 42L could of course be made without benefit of the indicia marking assembly, with the resultant tag being printed or otherwise marked on one side only, without departing from the spirit of the invention.

It will be noted that FIG. 3 is a top view of structure shown in FIG. 2 and denotes the section line on which FIG. 4 is taken. It will be seen in FIGS. 3 and 4 that the portable hand tool of the present invention is split substantially along the vertical center line on the left end and along the horizontal axis throughout the central portion and right end.

The left end portion is enlarged and has integral therewith, an adhesive tape spool support member 52. The spool support 52 for the upper tape spool 54U extends from the housing section 42L, while the spool support for the lower tape spool 54L extends from the housing section 42U. Immediately to the right of the tape spools 54U and 54L is the pivot pin 44, which is positioned with two pins 46 located in a groove G in the sides of the

housing sections

42U and 42L. The central section of pivot pin 44 has two flats 48 thereon, one of which engages the head of a threaded member 62 positioned in the end of the tape feeder bar 60. As are the other parts, the tape feeder bar is generally symmetrical and is illustrated in FIG. of the drawings. Rotation of the head of the thread, member 62 positions the right end of the tape feeder bar 60 in proper relationship to the cutter member carried in the indicia marking assembly 80, which will be described hereinafter. The head of the threaded member 62 is maintained in contact with the flat 48 on the pivot 44 by means of a compression spring 68 positioned on a shaft 66 located within the housing. One end of the spring 66 is in contact with a housing flange 67 while the other end is in contact with a flag member 69, the tab portion of which depends downwardly into a space 64 on the feeder guide portion 61. Two ears 63 extend from the feeder bar 60 for actuation of same to advance the adhesive tape into position, prior to the cut off and indicia marking. The ears 63 extend through a horizontal slot in the housing members. With this construction, the feeder bar 60 is always maintained in its rearwardmost position. It will be noted in FIG. 9 that the feeder guide portions 61 are guided between portions which extend from the housing.

The adhesive tape is maintained in contact with the feeder bar 60 by means of spring loaded wheels '82 carried by the indicia marking assembly 80. Each wheel 82 has a hub 84, with teeth 86 thereon. The axle shaft 88 on which the wheel and hub are mounted extends into slots 92 in the indicia marking housing 80. An L-shaped hollow member 94 is slidably positioned in the fixed part of the indicia marking assembly 80, with the foot of said L-shaped member maintained in contact with the hub by means of tension spring 96, one end of which is secured to the fixed portion of the housing 81, While the other end thereof is secured to the slida-ble member.

The indicia marking rollers are located on shaft 102 and are driven by gears on shaft 104. While each of

shaft members

102 and 104 are flanged and retained within the housing assembly 81 is joined by screws, rivets or the like which extend not only through the housing assembly 81, but also through the upper and

lower housings

42U and 42L thus assuring proper positioning of same in the said housings. Additionally, shaft 104 has positioned thereabout, a geared adjustment key 106, which is adjustable and positioned with a detent device (spring loaded) carried on the wire anvil 108. The adjustment key has a spur gear on the left end thereof, which is adapted to cooperate with an internal gear 112 on each of the gear wheels 114. The outside of each of the gear wheels 114 has a plurality of notches 116 Which cooperate with the fingers of a leaf spring 118, so that when the adjustment key 106 is rotated, the indicia marking roll 122 will remain in the adjusted position through the cooperation of the external teeth on gear wheel 114, whereafter the adjustment key 106 is moved to the right so as to engage the internal gear teeth on the next wheel. The grooves 124 in adjustment key cooperate with the detent D to position the internal gear of the center wheel and when this is complete, the adjustment key 106 is then again moved to the right for the adjustment of the third wheel 114. As will be noted in FIG. 2 a window 126 is provided in housing 42 to permit the operator of the hand tool of the present invention to observe the position of the indicia marking wheels without dis-assembly of the tool. This is accomplished by placing corresponding characters on the notched surface of gear wheel 114, which when observed will indicate the relative position of each of the indicia marking wheels 122 through the window.

The indicia marking wheels are made from an absorbent material such as porlon, which can be saturated with ink, thus simplifying the complete structure by the elimination of a stamp pad within the assembly.

From the foregoing description, it is apparent that the present invention is simple, durable and solves a problem of long standing. In operation, the indicia marking wheels 122 are adjusted in the manner described using the adjustment key 106 and viewing the adjustment through the window in the housing. Assuming the device is loaded with tape, the tape T is advanced to the stop 128 in the indicia marking assembly 80, thus rotating wheel 82 to make the tape T rigid, by means of the feeder bar 60. j

The hub 86 moves the L-shaped finger member against the tension spring 96 which is secured to pins and 97.

Pin 97 being in the fixed portion of the indicia marking assembly 80, while pin 95 is in the displacable member and guided by the said indicia marking assembly 80. When the tape T reaches the limit of travel, the stop on the hub 86 will be in engagement with the L-shaped member 99 and the car 63 on the feeder bar 60 will be in contact with the end of the slot in the housing.

The last operation is the pivoting of the

housing assemblies

42U and 42L to actuate the cutoff 132 against the end 134 of the feeder bar 60, thereafter applying the predetermined indica on each face of the tape T and securing same to a wire positioned between the tape '1' and the anvils 108.
