Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
186 words
An adjustable device for carrying and storing various sizes of chain saw cutting chains in orderly untangled fashion, ready for use, comprising two identical components, each of the two identical components comprising a bar to having opposite ends and a plurality of serrations on a longitudinal face thereof, said serrations facilitating a face to face interlocking relationship between the two identical components at any point throughout the length of the bar, said components further comprising at one end of said bar an arcuate portion having a groove around the circumference thereof and configured in such a way so that a portion of a chain saw cutting chain may be inserted, said adjustable device further comprising a separate locking mechanism in operational contact with each of said components so as to interlock the serrations of said two components and maintain said components in a fixed position, said arcuate portions of each component being located at opposing ends of the locked together components, wherein said chain saw cutting chain is retained in said grooves of said arcuate portions when said components are locked together by said locking mechanism.
Claim 2
Dependent Claim
186 words
An adjustable device for carrying and storing various sizes of chain saw cutting chains in orderly untangled fashion, ready for use, comprising two identical components, each of the two identical components comprising a bar to having opposite ends and a plurality of serrations on a longitudinal face thereof, said serrations facilitating a face to face interlocking relationship between the two identical components at any point throughout the length of the bar, said components further comprising at one end of said bar an arcuate portion having a groove around the circumference thereof and configured in such a way so that a portion of a chain saw cutting chain may be inserted, said adjustable device further comprising a separate locking mechanism in operational contact with each of said components so as to interlock the serrations of said two components and maintain said components in a fixed position, said arcuate portions of each component being located at opposing ends of the locked together components, wherein said chain saw cutting chain is retained in said grooves of said arcuate portions when said components are locked together by said locking mechanism.
Claim 3
Dependent Claim
87 words
The device of claim 1 wherein the separate locking mechanism comprises means for releasing to a point where resistance of the interlocking serrations on the bar of the two identical components may be overcome, said locking mechanism further comprising spring tension means which maintains said interlocking action of the identical components while allowing adjustments in length to be made to facilitate retaining the chain saw cutting chain on the device until the two identical components may be secured to a fixed position by the separate locking mechanism.
Claim 4
Dependent Claim
44 words
The device of claim 1 wherein the groove of the arcuate is of sufficient depth to contain the cutting edges of chain saw cutting chains, protecting the cutting edges from coming in contact with other objects, maintaining the cutting edges in a sharpened condition.
