Abstract
Abstract A feed mechanism for locating fastener attachment members one at a time in position for dispensing through a needle or the like, said mechanism comprising a feed wheel having teeth and a pawl resiliently urged toward the wheel, and said pawl slidably moveable across the side of said wheel into and out of the space between the teeth thereof. In addition there is disclosed depressible means for engaging the pawl to move it away from said wheel to permit fastener attachment members to be withdrawn from the apparatus.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
66 words
In an apparatus for dispensing fastener attachment members or the like including means for forcing a portion of a fastener attachment member through a hollow slotted means or the like, and an indexing mechanism including an indexing wheel having a plurality of teeth, the improvement in the indexing mechanism comprising means for urging rotation of said wheel more than one tooth each time it is rotated.
Claim 2
Dependent Claim
66 words
In an apparatus for dispensing fastener attachment members or the like including means for forcing a portion of a fastener attachment member through a hollow slotted means or the like, and an indexing mechanism including an indexing wheel having a plurality of teeth, the improvement in the indexing mechanism comprising means for urging rotation of said wheel more than one tooth each time it is rotated.
Claim 3
Dependent Claim
63 words
In an apparatus according to claim 1 in which said indexing wheel is mounted on a shaft for rotation, in which said means for urging rotation of said wheel comprises a pawl positioned for rotation about said shaft and having pusher means for engaging said teeth to rotate the feed wheel, and resilient biasing means urging said pawl pusher means towards said wheel.
Claim 4
Dependent Claim
39 words
In an apparatus according to claim 2 in which resilient biasing means is provided which engages said wheel to prevent it from rotating except when rotated by force sufficient to overcome the force applied by said resilient biasing means.
Claim 5
Dependent Claim
19 words
In an apparatus according to claim 1 including means for preventing rotation of said wheel more than one tooth.
Claim 6
Dependent Claim
51 words
In an apparatus according to claim 1 in which said means for urging rotation comprises a pawl having an edge pusher means which is positionable between teeth of said wheel to rotate same and which slides across the side of the teeth during positioning thereof in location to rotate said wheel.
Claim 7
Dependent Claim
24 words
In an apparatus according to claim 5 in which the edge pusher means of said pawl urging said wheel to rotate is substantially flat.
Claim 8
Dependent Claim
21 words
In an apparatus according to claim 5 in which the edge surface means slideable over said teeth is also substantially flat.
Claim 9
Dependent Claim
44 words
In an apparatus according to claim 7 in which said edge surface means engaging said teeth to rotate same and in which said edge surface means slideable over said teeth are at an angle of less than ninety degrees with respect to each other.
Claim 10
Dependent Claim
23 words
In an apparatus according to claim 8 in which said angle is less than about seventy degrees and more than about thirty degrees.
Claim 11
Dependent Claim
68 words
In an apparatus for dispensing fastener attachment members or the like, said apparatus comprising an indexing wheel mounted on a shaft for rotation, said wheel having a plurality of teeth, means for supporting the shaft for rotation, a pawl supported on the shaft for rotation, and having a pawl pusher means and a bowed washer positioned about said shaft and urging said pawl pusher means towards said wheel.
Claim 12
Dependent Claim
68 words
In an apparatus for dispensing fastener attachment members or the like, said apparatus comprising an indexing wheel mounted on a shaft for rotation, said wheel having a plurality of teeth, means for supporting the shaft for rotation, a pawl supported on the shaft for rotation, and having a pawl pusher means and a bowed washer positioned about said shaft and urging said pawl pusher means towards said wheel.
Claim 13
Dependent Claim
32 words
In an apparatus according to claim 10 in which depressible means is provided for engaging said pawl and forcing it along the shaft away from said wheel to depress said bowed washer.
Claim 14
Dependent Claim
23 words
In an apparatus according to claim 11 in which spring biasing means is provided for urging said depressible means away from said pawl.
Claim 15
Dependent Claim
28 words
In an apparatus according to claim 10 said pawl includes edge means which is slideable over the side of the teeth and into the space between the teeth.
Claim 16
Dependent Claim
64 words
In an apparatus for dispensing fastener attachment members or the like, said apparatus comprising an indexing wheel mounted on a shaft for rotation, said wheel having a plurality of teeth, pawl means supported for rotation on said shaft, means for urging said pawl means towards said wheel, and means for engaging said pawl to move it axially along said shaft away from said wheel.
Claim 17
Dependent Claim
64 words
In an apparatus for dispensing fastener attachment members or the like, said apparatus comprising an indexing wheel mounted on a shaft for rotation, said wheel having a plurality of teeth, pawl means supported for rotation on said shaft, means for urging said pawl means towards said wheel, and means for engaging said pawl to move it axially along said shaft away from said wheel.
Claim 18
Dependent Claim
23 words
In an apparatus according to claim 14 in which spring biasing means is provided for urging said depressible means away from said pawl.
