Abstract
Abstract Dispensing of fasteners by a device which receives an assemblage of the fasteners and is able to expel them individually through, for example, a slotted hollow needle. The dispensed fasteners can be used generally in the attachment of items to one another and, in particular, for the labeling of textile goods and the like with information bearing tags. The device includes a trigger operated feed mechanism and a simultaneously operable expulsion mechanism. Both mechanisms are controlled by the tip of a lever which is proportioned and disposed in the device to execute linear motion. The feed mechanism is disengageable from the remainder of the device to permit clearance of the inserted assemblage or the removal of jams. The feed mechanism additionally is operated by a planar pawl having a tooth that extends into contact with indentations on the periphery of a feed wheel.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
101 words
Apparatus for dispensing fasteners comprising a device for receiving an assemblage of fasteners; means for feeding the fasteners received by said device; and a pivoting linkage having two separate pivot points at opposite ends of said link for controlling the feeding means; wherein the feeding means includes a reciprocal slide and a feed pawl pivotally connected to respective opposite ends of said link at said separate pivot points; said slide includes spaced apart projections which are successively engaged during the feeding of said fasteners; and said projections are engaged by a lever which is operated by a trigger of said device.
Claim 2
Dependent Claim
101 words
Apparatus for dispensing fasteners comprising a device for receiving an assemblage of fasteners; means for feeding the fasteners received by said device; and a pivoting linkage having two separate pivot points at opposite ends of said link for controlling the feeding means; wherein the feeding means includes a reciprocal slide and a feed pawl pivotally connected to respective opposite ends of said link at said separate pivot points; said slide includes spaced apart projections which are successively engaged during the feeding of said fasteners; and said projections are engaged by a lever which is operated by a trigger of said device.
Claim 3
Dependent Claim
32 words
Apparatus as defined in claim 1 wherein the feeding means includes a feed wheel having peripheral indentations for engaging individual ones of said fasteners and the feed pawl operates said feed wheel.
Claim 4
Dependent Claim
18 words
Apparatus as defined in claim 1 wherein the feed pawl is in the form of a planar member.
Claim 5
Dependent Claim
17 words
Apparatus as defined in claim 1 wherein said lever is positioned between said projections of said slide.
Claim 6
Dependent Claim
16 words
Apparatus as defined in claim 4 wherein said projections are in the form of cylindrical posts.
Claim 7
Dependent Claim
14 words
Apparatus as defined in claim 5 wherein said projection posts are of unequal size.
Claim 8
Dependent Claim
17 words
Apparatus as defined in claim 1 wherein said lever engages said feeding means along a linear path.
Claim 9
Dependent Claim
32 words
Apparatus as defined in claim 7 wherein said trigger is pivotally connected to said apparatus and includes a fixed projection which moves along a slot of said lever for the control thereof.
Claim 10
Dependent Claim
26 words
Apparatus as defined in claim 1 further including a link pivotally connected to said lever by the end positions thereof and pivotally connected to said apparatus.
Claim 11
Dependent Claim
26 words
Apparatus as defined in claim 1 wherein said device includes a slotted hollow needle at the frontal portion thereof through which said fasteners are expelled individually.
Claim 12
Dependent Claim
40 words
Apparatus as defined in claim 1 wherein said trigger is pivotally mounted on said device along a line of tangency with a feed wheel of said device with said line of tangency being perpendicular to the axis of said fasteners.
Claim 13
Dependent Claim
59 words
Apparatus as defined in claim 1 wherein the device includes a slotted hollow needle at the frontal portion thereof through which said fasteners are expelled individually; and said device has a frontal portion below said needle which lies within an angle no greater than 15° at a plane tangent to said frontal portion at the position of said needle.
Claim 14
Dependent Claim
46 words
Apparatus as defined in claim 1 wherein said trigger is pivotally mounted and has a central finger gripping portion with a line of tangency that extends to the axis of feed of the device and forms therewith an angle in the range from 85° to 95°.
Claim 15
Dependent Claim
54 words
Apparatus for dispensing fasteners comprising a device for receiving and feeding an assemblage of fasteners, including a feed pawl and an antibackup mechanism for said feed pawl; and means for simultaneously disengaging said feed pawl and said antibackup mechanism; wherein the disengaging means comprises a member with a shoulder for engaging said antibackup mechanism.
Claim 16
Dependent Claim
54 words
Apparatus for dispensing fasteners comprising a device for receiving and feeding an assemblage of fasteners, including a feed pawl and an antibackup mechanism for said feed pawl; and means for simultaneously disengaging said feed pawl and said antibackup mechanism; wherein the disengaging means comprises a member with a shoulder for engaging said antibackup mechanism.
Claim 17
Dependent Claim
24 words
Apparatus as defined in claim 14 wherein said feed pawl includes a planar portion and the disengagement means is engageable with that planar portion.
Claim 18
Dependent Claim
27 words
Apparatus as defined in claim 14 wherein the disengaging means comprises a member which is movable transversely with respect to the direction of feed of said attachments.
Claim 19
Dependent Claim
25 words
Apparatus as defined in claim 14 wherein the means for disengaging said feed pawl from the feeding mechanism operates without affecting the drive portion thereof.
