Abstract
Abstract Compactly nested, generally V-shaped clips, each intended to hold the end of a sinuous spring, are stacked in a chute. Ushaped staples or nails are separately stacked in a magazine. In each clip there are two angularly related flanges, both perforated for fasteners. The clip to be fastened is machine fed to a fastening station where the clip is secured by a first fastener and the upper flange of the clip is bent into position to hold the spring securely. The end of the sinuous spring is then inserted between the flanges and a second fastener may then, if desired, be driven through both flanges. When and if the second fastener is driven, no clip can be advanced from the clip stack, the clip transfer mechanism being manually rendered inoperative.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
101 words
In a combined stapler and clipper, a chute for a stack of overlappingly nested and compacted generally J-shaped clips each having a pair of flanges angularly related to each other and of unequal lengths, a staple magazine, means for denesting the leading clip of said stack, means including a staple driver for stapling the longer flange only of the denested clip to an article of work at a given stapling station and means associated with said staple driver and operatively connected thereto for bending the shorter flange toward said longer flange at said given station and insufficiently to close said clip.
Claim 2
Dependent Claim
101 words
In a combined stapler and clipper, a chute for a stack of overlappingly nested and compacted generally J-shaped clips each having a pair of flanges angularly related to each other and of unequal lengths, a staple magazine, means for denesting the leading clip of said stack, means including a staple driver for stapling the longer flange only of the denested clip to an article of work at a given stapling station and means associated with said staple driver and operatively connected thereto for bending the shorter flange toward said longer flange at said given station and insufficiently to close said clip.
Claim 3
Dependent Claim
21 words
The stapler and clipper of claim 1, and means for rendering inoperative the clip-transferring means while maintaining the staple-driving means operative.
Claim 4
Dependent Claim
14 words
The stapler and clipper of claim 1, the flange-bending means comprising a reciprocating hammer.
Claim 5
Dependent Claim
23 words
The stapler and clipper of claim 1, the flange-bending means comprising a roller and means for moving the roller against the shorter flange.
Claim 6
Dependent Claim
45 words
The stapler and clipper of claim 1, at least one set of the corresponding flanges of the clips in the stack being closely compacted to each other in the nested position thereof, said chute being inclined to both flanges of the stack of clips therein.
Claim 7
Dependent Claim
117 words
In a combined stapler and clipper, a chute for a stack of nested generally J-shaped clips each having a pair of flanges angularly related to each other and of unequal length, a staple magazine, means for denesting and tRansferring a clip from said stack to a stapling station, means for stapling the longer flange to an article of work and means for bending the shorter flange toward the longer flange an amount insufficient to close the clip, the stapling means being pneumatically operated, and an operative connection between the stapling means and the means for bending the shorter flange, the bending means being operated by said connection on the driving of a staple by said stapling means.
Claim 8
Dependent Claim
117 words
In a combined stapler and clipper, a chute for a stack of nested generally J-shaped clips each having a pair of flanges angularly related to each other and of unequal length, a staple magazine, means for denesting and tRansferring a clip from said stack to a stapling station, means for stapling the longer flange to an article of work and means for bending the shorter flange toward the longer flange an amount insufficient to close the clip, the stapling means being pneumatically operated, and an operative connection between the stapling means and the means for bending the shorter flange, the bending means being operated by said connection on the driving of a staple by said stapling means.
Claim 9
Dependent Claim
49 words
The stapler and clipper of claim 1, the means for transferring the clip being pneumatically operated and the means for bending the flange of the clip being operatively connected to the staple-driving means and manually controlled means for rendering inoperative the clip-transferring means while the staple-driving means remains operative.
Claim 10
Dependent Claim
35 words
The stapler and clipper of claim 6, the chute being inclined to the horizontal and maintaining the longer flanges of the clip in the clip stack substantially horizontal during the movement thereof through the chute.
Claim 11
Dependent Claim
31 words
The combined stapler and clipper of claim 1, and means associated with the chute for positioning said leading clip at said given stapling station during the bending of said shorter flange.
Claim 12
Dependent Claim
24 words
The combined stapler and clipper of claim 1, the means for denesting said leading clip also advancing said clip to said given stapling station.
