Definitions

  • the present invention relates to an assembly of plastic attachments individually securable to material by being dispensed from an attachment dispensing device and to an attachment dispensing device. More particularly the invention is concerned with an attachment dispensing device of the kind having two hollow needles for penetrating the article to which an attachment is to be secured, and with an attachment assembly for use in a device of this kind.
  • tags and the like were attached to garments and other soft goods by strings or straight pins.
  • new tagging systems were developed which increased the speed of the tagging operation and made it more efficient by decreasing the time and labor required.
  • the first tagging system was commercialized in the 1960's when Dennison Manufacturing Company of Framingham, Massachusetts began selling an assembly or clip of plastic attachments and an attacher therefore, both of which are disclosed in U.S. Patent No. 3,103,666 of September 16, 1963 to Arnold Bone entitled "Attaching Apparatus".
  • Those attachments included a T-bar end and an enlarged paddled end connected by a flexible filament which is stretched to increase its strength.
  • the attachments are injection moulded in clips or assemblies of 20 to 50 attachments each.
  • the attachments are held together by means of a single connecting bar.
  • the T-bar ends of the attachments are situated in spaced, parallel relation along the connecting bar.
  • the attaching device employes a hollow needle designed to penetrate the object to be tagged and the tag. After the needle was properly positioned, a single attachment was severed from the assembly and the T-bar end thereof is pushed through the channel in the needle such that the T-bar end of the attachment is situated on one side of the garment and the paddle end of the fastener on the other.
  • the attachments of the type described in the Bone patent became widely used in the industry. They were employed for attaching all kinds of tags and labels to articles to be sold at retail, where the attachments proved particularly effective in preventing unscrupulous shoppers from switching tags, that is, removing a tag from a low priced article and attaching it to a higher priced article. They are used as well for securing groups of articles together, such as shoes in a pair or matching tops and bottoms. The attachments were also useful for many other purposes.
  • the attachments could be applied at an extremely rapid rate, even by relatively unskilled personnel, thus greatly reducing the cost of the tagging operation.
  • other companies have distributed similar types of attachments and attaching devices. This type of system has virtually surplanted all other attaching methods.
  • the Lankton patent also discloses an embodiment, as far as I know never commercialized, which utilizes a connecting bar on the paddle end as well as on the T-bar end. However, unlike the T-bar ends, the enlarged paddle ends are connected directly without spacing elements, to the connecting bar.
  • 4,533,076 to Bourque discloses an attachment dispensing device as described in the preamble of Claims 1 and 12, using an assembly of attachments of the kind referred to in the preamble of Claim 7; this device uses an attachment assembly in which the attachments have two T-bar ends connected at their tips in a continuous stock.
  • the present invention is concerned with attachment dispensing devices of the kind using two needles.
  • What is now proposed is a differently configured attachment assembly to that disclosed in the Bone patent referred to in the previous paragraph and a specially designed device for dispensing the attachments.
  • Each attachment has a first and a second T-bar end. The ends are joined by a flexible filament.
  • the now proposed attachment assembly includes two connecting bars. Each of the T-bar ends is connected to a different one of the connecting bars.
  • the attachments now proposed have T-bars at both ends which are joined to two connecting bars.
  • the attachment assembly now proposed includes connecting bars.
  • the assembly particularly described below has further features of difference with regard to these prior art assemblies as will emerge from the detailed description given below.
  • the attachment dispensing device embodying the present invention that is also described in detail hereinafter, includes a recess which has spaced portions adapted to accept the respective connecting bars of the attachment assembly. This structure permits the attachments to move through the attaching device with greater precision and reduced chance of jamming.
  • the attachment dispensing device to be described includes simultaneously movable ejector rods, both of which are connected to a single actuator.
  • dual indexing means co-operate with the attachment assembly, proximate each side thereof, such that the indexing operation is smooth and reliable.
  • an attachment dispensing device loaded with an assembly of attachments as claimed in claim 1.
  • each T-bar end is joined to the respective connecting bar by a part that spaces the T-bar end from the connecting bar. This part is advantageously used in advancing the attachment assembly through a dispensing device as will be described below.
  • the T-bar ends are substantially perpendicular to the connecting bars.
  • the connecting bars and the attachments are integral and composed of molded plastic.
  • an attachment dispensing device for dispensing individual attachments from an assembly of attachments which is as described above, the attachment dispensing device comprising a housing, two hollow needles providing channels through which the respective T-bar ends of an attachment are moved to dispense the attachment, means in the housing actuable to push the T-bar ends through said channels, a recess in said housing through which an assembly of attachments is advanceable to bring successive attachments to a dispensing position, and means actuable to advance an assembly of attachments through said recess, characterised in that the recess has respective spaced sections for receiving the connecting bars of an assembly of attachments and means are provided for severing the T-bar ends of an attachment to be dispensed from said connecting bars.
  • the means for pushing the T-bar ends preferably comprises a pair of rods movable along respective ones of said channels.
  • the device further comprises means for simultaneously moving the ejector rods.
  • the means for simultaneously moving the ejector rods may comprise a respective slide connected to each rod and means movable with a trigger mounted to the housing between a first position where the rods are and coacting with the slides to move them.
  • the rods in the embodiment to be described are movable from a rest position spaced from the needles to allow the next attachment to be dispensed to be advanced to the above-mentioned dispensing position.
  • the housing preferably includes respective guide means for guiding lengthwise movement of the rods.
  • the means for advancing the assembly of attachments through the recess in the housing may comprise respective gears intersecting the recess to engage the assembly proximate each of the connecting bars thereof. More particularly where the attachment assembly has a respective spacer part between each T-bar end and the proximate connecting bar, the gears are situated to engage the respective spacer parts.
  • the gears may be intermittently moved by an indexing mechanism that is coactable with further slides movable by actuation of the trigger which also actuates the rods. More particularly in the embodiment to be described, depressing the trigger causes movement of the rods and releasing the trigger causes movement of the gears.
  • the attacher of the present invention includes a housing, generally designated A, which has two halves 10 and 12.
  • the housing havles 10, 12 are substantially mirror images of each other and are fastened together by a series of screws 14.
  • Housing A is generally pistol shaped and has a handle 16 with a depressable trigger 18 extending from its forward portion.
  • the front of housing A has a pair of oppositely oriented needles 20, 22 extending therefrom in spaced parallel relation.
  • the forward portion of housing A is provided with a recess 24 which extends there through in a direction generally perpendicular to the plane of needles 20 and 22.
  • Recess 24 has a generally "H" shaped configuration and includes spaced portions 26, 28 adapted to receive the connecting bars 30, 32, respectively, of the assembly of attachments, generally designated B.
  • each assembly B of attachments includes a plurality of attachments 36 situated in a substantially spaced, parallel relation and connected between connecting bars 30 and 32.
  • Each of the attachments includes first and second T-bar ends 38, 40. The T-bar ends are connected by a thin stretched plastic flexible filament 39.
  • the layers are held in face-to-face relation.
  • the attacher is manipulated such that the material and attacker are moved relative to each other until needles 20, 22 penetrate the layers.
  • Trigger 18 is actuated causing T-bars 38 and 40 to move through hollow needles 20 and 22.
  • the T-bar ends 38 and 40 travel down the channels in needles 20 and 22 they are substantially parallel to each other.
  • the needles 20 and 22 are parallel and have longitudinal openings facing one another
  • the T-bar ends pivot back to their original orientation, parallel to the surface of the layers, as filaments 39 bows.
  • the T-bar ends thereafter lodge adjacent the rear surface of the layers, as shown in Fig. 1.
  • the attacher and material are then moved away from each other, leaving the attachment anchored.
  • the internal indexing mechanism of the attacher advances the assembly of attachments through recess 24 in housing A such that the next attachment in the assembly achieves a dispensing position in which its T-bar ends align with needles 20 and 22.
  • trigger 18 is pivotally mounted to the housing by pin 46.
  • Trigger 18 is pivotally connected to lever 48 by pin 50 located near the lower end of lever 48 which cooperates with slot 49 in lever 48 to provide for a lost motion connection.
  • Lever 48 is movably mounted to housing A proximate its mid section by pin 52.
  • Lever 48 and thus trigger 18 are spring loaded towards the undepressed position shown in Fig. 2 by means of a tension spring 54 connected between lever 48 at point 56 and housing A at point 58.
  • the upper end of lever 48 is bifuricated, with the legs 48a and 48b associated with a different one of two slides 60a, 60b.
  • Each slide 60a, 60b is situated between a pair of guides 62 and 64 on each housing half 10, 12 for movement within housing A.
  • Slides 60a, 60b have apertures adapted to accept the ends of ejector rods 66, 68 respectively.
  • Each of the ejector rods 66, 68 is bent at a right angle near its rear end so as to fit into the respective apertures in slides 60a, 60b.
  • the upper end of leg 48a of lever 48 has an elongated opening 70 therein so as to accommodate the ejector rod and its sleeve as lever 48 is pivoted about pin 52.
  • ejector rods 66 and 68 are in a rest position situated behind needles 20 and 22, a distance sufficient to permit the T-bar ends 38, 40 of an attachment to be positioned in alignment with the channels of the respective needles 20, 22.
  • lever 48 rotates about pin 52 and slides 60a, 60b move forward.
  • ejector rods 66 and 68 are simultaneously moved toward needles 20, 22 such that the rods cause the T-bar ends 38, 40 of the attachment to move through the channels of needles 20 and 22, respectively.
  • Each housing half 10, 12 is provided with two ejector rod guide members 61 or 63.
  • Members 61, 63 function to guide the movement of ejector rods 66, 68 to insure accurate movement and to eliminate jamming or bending of the rods.
  • Each half 10, 12 of housing A is provided with a knife blade 72 which is preferably removable from the housing so that it can be replaced when dull.
  • the function of knife blade 72 is to sever the T-bar ends of the attachments from their respective connecting bars as the ejector rod pushes the T-bar end of the attachment through the needle.
  • the T-bar ends 38, 40 of the attachments 36 are connected to and spaced from the respective connecting bars 30, 32 by bridge elements 74 which is relatively thin. Elements 74 are long enough to space the T-bar ends from the connecting bar associated therewith a distance sufficient to permit engagement of the bridge element by the gear wheels which make up the indexing mechanism. As seen in Figs. 3 and 4, bridge elements 74 cooperate with the teeth of indexing gears 78 to advance the assembly of attachments through the housing. Two indexing gears 78 are provided, one on each side of the housing. Each cooperates with the bridge element 74 on a different side of the attachment.
  • the fastener indexing means includes first and second parallelly situated mechanisms one of which is illustrated in Figs. 1, 2 and 3. For simplicity, the operation of only one indexing mechanism will be described, it being understood that both mechanisms are operated simultaneously by the movement of a single trigger 18.
  • Each indexing mechanism includes an indexing gear 78 rotatably mounted to the housing half. Gear 78 cooperates with lower and upper spring loaded pawls 80, 82 also mounted in that housing half. Each of the lower pawls 80 is pivotably mounted on a portion 84 of slide 86 by pin 87. A spring 81 urges the pawl 80 clockwise, such that tooth 83 normally engages gear 78. Slide 86 is reciprocated relative to the housing as trigger 18 is depressed, moving pawl 80 between the position shown in Fig. 3 and that shown in Fig. 4.
  • slide portion 86 has a recessed portion 88 into which the upper portion of one of the legs of lever 48 is received forming a lost motion connection with lever 48 such that a relatively large amount of movement of lever 48 results in a relatively small movement of slide 86 and hence slide portion 84.
  • a downwardly projecting finger 90 which cooperates with a spring loaded lever 92 to limit the movement of the slide.
  • lever 48 is rotated clockwise due to the action of spring 54, slide 86 moves rearwardly.
  • Spring 81 urges tooth 83 of pawl 80 into engagement with the teeth of gear 78, and gear 78 rotates through an arc sufficient to bring the next attachment 36 into alignment with the needles. This occur because pawl 82 is cammed against the action of spring 95, allowing gear 78 to rotate in the counterclockwise direction.
  • Upper pawl 82 normally prevents movement of the gear 78 in the clockwise direction unless it is manually pivoted in a clockwise direction by depression of projection 98.
  • Projection 98 extends above the housing such that it is manually accessible.
  • finger 85 of pawl 82 and finger 83 of pawl 80 are no longer enmeshed in the teeth of gear 78, such that gear 78 can move freely. This permits the assembly of attachments to be removed from the housing.
  • the indexing mechanism and the ejector mechanism illustrated in the drawings are modified versions of typical corresponding mechanisms which have been widely used in single needle attachers.
  • the important aspect is that the mechanism provides for simultaneous election and indexing of specially configured attachments with dual T-bars 38, 40.
  • attachments which includes attachments with T-bars at either end.
  • the attachments are situated in substantially parallel, spaced relation between first and second substantially parallel connecting bars.
  • the attacher which has been described includes a recess having spaced sections adapted to receive the connecting bars and a pair of oppositely oriented, parallel needles extending from the front thereof. Simultaneously displaceable ejector rods serve to move the respective T-bar ends through the needles to dispense an attachment. Means are provided for indexing the assembly through the housing as each attachment is dispensed. The attachments are automatically severed from the connecting bars as they are dispensed.
