9 Claims, 11 Drawing Figures PATENTEB AUG 2 61975 SHKET 1. [IF 2 TAG AITACI-IER BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to the art of applying fasteners, and specifically to apparatus for attaching tags to articles such as merchandise by means of fasteners.

2. Description of the Prior Art An early disclosure of a tag attacher is found in French Pat. No. 668,545, patented July 15, 1929. A later version of a tag attacher is disclosed in U.S. Pat. No. 3,103,666 in which there is illustrated a relatively short assembly rod and relatively few attachments or fasteners. The economics is such that it is too costly to produce a fastener assembly having such a small number of fasteners as illustrated in US. Pat. No. 3,103,666. Commercial fastener assemblies have thus included 20, 25, 35, 50 and 100 fasteners. Not only is it economical to mold assemblies having large numbers of fasteners, but the greater the number of fasteners per assembly the less often it is required to load the tag attacher. A yet later version of a tag attacher is disclosed in US. Pat. No. 3,650,452, the entire disclosure of Y which is incorporated herein by reference. Another version of a tag attacher is disclosed in US. Pat. No. 3,759,435. In US. Pat. No. 3,733,657 there are described attachments and a method of separating the attachments which can cause the relatively sharp ends of the necks or connectors to catch on or snag fabric merchandise. This is especially true with delicate merchandise, such as lingerie. It has been found that as a bar section is severed from its respective connector and to some extent as the tooth of the pawl moves over a tooth of the ratchet wheel in an apparatus such as shown in US. Pat. No. 3,650,452, vibrations are set up in the spring, producing a ringing sound audible to the user.

SUMMARY OF THE INVENTION The invention employs apparatus for attaching tags to articles such as merchandise using a conventional fastener assembly. Each fastener of the assembly has a bar section and a button or head section joined by a filament section. The bar sections of the fasteners are connected to a rail or rod by respective connectors or necks. A considerable number of fasteners, for example, twenty or more, are connected to a single rail. During use of the apparatus, the rail is guided in a guideway and the fastener assembly is advanced by advancing means. The advancing means advance successive bars to a position in alignment with a bore of a needle. The bars of the fasteners are successively severed from the respective connectors and a push rod pushes the bar section through the needle bore as the filament section passes along a side opening in the needle. The exposed ends of the connectors which have been advanced beyond the outfeed end of the guideway are prevented from snagging the merchandise by means of a shield in accordance with the invention. The shield is comprised in the preferred embodiments of a deflectable tube connected to the body of the tag attacher at the outfeed side of the guideway. As the tube is likely to contact the merchandise as the needle is inserted through the merchandise, the deflection of the shield prevents the shield from interfering with the attaching operation. The shield can be constructed of low cost plastics or rubber material which deflects readily. There is enough clearance between the inside of the tubular shield to obviate friction resistance as the fastener assembly is being advanced and to enable the rail and the associated connectors to drop out when the last fastener has been severed from its respective connector. The apparatus includes a return spring for returning various of the operative components of the apparatus to an initial position to complete a cycle of operation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings there is shown apparatus 20 that uses fasteners generally indicated at 21 which are interconnected to provide a fastener assembly 22. A typical use of a fastener 21 is illustrated in FIG. 1, wherein a tag 23 is shown attached to a garment 24. Each fastener 21 of the assembly 22 includes a bar section 25 and a button or head section 26 joined by a filament or string section 27.

The fastener assembly 22 is constructed of plastics material such as nylon or the like and can be molded into a unitary construction such that each of the fasteners 21 is integrally connected to a rod or rail 22' by a connector 28.

With particular reference to FIGS. 2 and 3, the apparatus 20 is shown to include a body 20' constructed of body sections or

side plates

29 and 30. The body section 29 has posts or pivots 31, 32 and 33 molded integrally therewith. The body section 29 has a handle portion 34 which is adapted to fit against the palm of the users hand. An operating member or lever 35 pivotally mounted by the pivot 31 is engageable by the users fingers. When squeezed, the lever 35 is pivoted counterclockwise and an associated drive lever 36 is also pivoted counterclockwise. A spiral tension spring 41 is connected at one end to a post 29 molded integrally with the body section 29 and at its other end through a hole 42 and the lever 36. The tension spring 41 urges the lever 36 clockwise (FIG. 3) to its home or initial position shown in FIG. 2. The body section 29 has

guides

47 and 48. A slide or guided member 49 is guided by the guide 47 and a slide 62, guided by the guide 48, has an integrally formed pin or projection 65 received in an elongated slot 66 in the lever 36. A push or drive rod 55 has a bent portion or pin 56 which extends into an elongated slot 54 and is received by the guided member 49. The push rod 55 is thus guided at its one end by the slide 49 and along its length by

grooves

57 and 59. The slide 62 is shown to have an elongated slot 67. Paw] 68 has a tooth 69 shown to be in engagement with a ratchet wheel 70. The pawl 68 hasa pin or boss 72 which is received in the elongated slot 67. The pawl 68 cooperates with the ratchet wheel 70 to provide a pawl and ratchet mechanism. The ratchet wheel 70 is shown to be formed integrally with a feed wheel 73 which engages the connectors 28 to feed the fastener assembly 22 through the apparatus 20.

There is shown a tubular member, specifically a needle, generally indicated at 76 mounted by the body section 29. The needle 76 terminates at a pointed piercing end 77 and has a through bore 78 (FIG. 7) and an elongated slot 82 (FIG. 3) in the side of the needle 76 which communicates with the bore 78. The elongated slot 82 is wide enough to allow the filament section 27 adjacent the bar section to pass along the slot 82 while the bar section 25 is passing through the bore 78. The needle 76 has an enlarged portion 80 which terminates at a cutting edge 81. The push rod 55 is guided in its reciprocating movement in alignment with the bore 78. As the operator is actuated from the position shown in FIG. 2 to the position shown in FIG. 3, the push rod pushes on the end of a bar section 25 which is in alignment with the bore 78 to cause the bar section 25 to be severed from its respective connector 28. In the position shown in FIG. 3, the pin 72 has reached an abutment 67 formed by one end of the slot 67, thus causing the pawl 68 to move to the left (as seen in FIG. 3) to move the tooth 69 of the pawl 68 over one tooth of the ratchet wheel 70. When the counterclockwise movement of the actuator 35 is complete, the bar section 25 has moved completely through bore 78 to the other side of the material 24 as best shown in FIG. 3. Upon release of the operating lever 35, the return spring 41 returns the lever 36, the actuator 35, the push rod 55, the slide 62 and the pawl 68 to their initial position shown in FIG. 1. Just before these components reach their initial positions, the other end 67 of the slot 67 abuts the pin 72 to cause counterclockwise rotation of the ratchet and feed wheels and 73 (FIGS. 2 and 3), thereby advancing the fastener assembly 22 until the next successive bar section 25 is in axial alignment with the bore 78 in the needle 76. The body section 29 includes a slot or guideway 87 for guiding the fastener assembly 22. The slot 87 has an infeed side and an outfeed side 121. The foregoing is a brief description of the apparatus disclosed in US. Pat. No. 3,650,452.

The body section 29 is provided with a connector or fitting 122 at the outfeed side of the guideway 87. Although the connector is shown to be integral with the body section 29, it can be suitably removably or permanently attached, if desired. A shield generally indicated at 123 is shown to be connected to the fitting 122. More particularly, the shield 123 is shown to comprise a generally tubular member 124, one marginal end of which is snugly but preferably removably received about the fitting 122. The tube 124 has a convoluted section 125 immediately adjacent its marginal end so that the tube 124, which is composed of a flexible resilient material, can readily deflect from the position shown in FIGS. 3 and 4 to the position shown in FIG. 8 so that when the tube 124 is moved into contact with an article, such as fabric material, during the tag attaching operation, then the tubular shield 123 can yield. This enables the apparatus 20 to apply tags to merchandise in inaccessible places as if the shield 123 were not present. As shown in FIGS. 3 and 4, the rail 22' and the respective connectors 28 from which the bar sections 25 of respective fasteners 21 have been severed extend into the space within the shield 123. There is clearance between the shield 123 and the rail 22 and its connectors 28 so that the shield 123 does not interfere with the free advance of the fastener assembly 22 as the feed wheel 72 is rotated counterclockwise (FIG. 3). It is preferred to make the shield 123 of such length that the end 22" of the rail 22 just emerges from the far end 129 of the shield 123 when the bar section 25 of the last fastener 21 has been severed from its respective connector 28. Thereupon, the rail 22' and the respective connectors 28 which remain connected to the rail 22 can pass freely out of the end 129. It is readily apparent that the shield 123 shields the severed ends of the connectors 28 from contact with the article to which the tag 23 is being attached.

Referring to the embodiment of FIG. 9, in which an alternative form of shield 123a is shown, it is noted that the shield 123a takes the form of a cylindrical tube 124a which does not have the convolutions 125 as in the embodiment of FIGS. 2 through 8. The tube 124a is however comprised of a very flexible resilient material as the tube 124 and can deflect in the manner shown by phantom lines 124a.

The shield 12317 of the embodiments of FIGS. 10 and 11 is shown to comprise a tube l24b connected to the fitting 122. The tube is shown to have a V-shaped cut 130 adjacent the end of the fitting 122. The cut 130 facilitates flexure of the tube and forms a hinge as indicated at 131 to facilitate flexure to the position shown by phantom lines 124b.

The

shields

123, 123a and 123b are shown to be of tubular construction but a split sleeve, or other shapes can be used in carrying out the invention. The shields can be made long enough for accommodating the longest length fastener assemblies, for example, 100 fasteners per assembly and if the user desires to use fastener assemblies having for example 50 fasteners per assembly, the user can simply cut off the excess length with a pair of scissors.

The

shields

123, 123a and 123b are composed of any suitable flexible resilient materials such as rubber, vinyl or other plastics material, a styrene-butadiene copolymer, or the like.

In accordance with another feature of the invention, there is provided a vibration dampener generally indicated at for dampening vibrations set up in the spring 41 during movement of the operative components of the apparatus 20 in a cycle of operation. The vibration dampener 140 dampens these vibrations and the concomitant ringing sound produced by the spring 41. The dampener 140 is shown to comprise a split sleeve 141 having a slot 142. The sleeve 141 is received about and is in contact with the outer surface of the spring 41. The sleeve 141 can be composed of rubber, flexible resilient plastics material, or other suitable materials. Other forms of vibration dampers can be used as for example a tube or rod of material (not shown) inside and in contact with the spring 41, a weight or other mass attached to the spring 41, or resilient materials such as rubber or felt pads in contact with the spring 41.
