Abstract

Abstract A telescopic cutting apparatus comprising an elongated outer tubular arm of not less than four feet in length; a first handle means coaxial with and closing off the lower end of said outer tubular arm; a biased electrical on/off switch means disposed within said handle means and being normally in the "off" position and requiring constant application of force to be translated into the "on" position. A second handle means mounted proximate the upper end of said outer tubular arm; adjustment means for varying the positioning of said second handle means axially and radially with respect to said outer tubular arm; an inner tubular elongated arm telescopically mounted within said outer tubular arm; locking means associated with said inner and outer tubular arms to lock said inner arm in selected relation to each; trimming means having an electrical motor drive mounted on the upper end of said inner arm; a conductor cord extending from said motor through said arms in series with said switch means and outwardly of said first handle means and terminating in a plug; said conductor being a fixed length equal to slightly more than the combined lengths of said inner and outer tubular arms; said conductor being permanently pre-coiled into a retractable spring portion having a length not greater than that of said first tubular member; whereby said conductor cord is free of slack at all times and at all adjustments of said telescopic arms.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 261 words
A telescopic cutting apparatus comprising: (a) an elongated outer tubular arm of not less than four feet in length; (b) a first handle means coaxial with and closing off the lower end of said tubular arm; (c) a biased electrical on/off switch means disposed within said handle means and being normally in the "off" position and requiring constant application of force to be translated into the "on" position. (d) a second handle means mounted proximate the upper end of said outer tubular arm; (e) adjustment means for varying the positioning of said second handle means axially and radially with respect to said outer tubular arm; (f) an inner tubular elongated arm telescopically mounted within said outer tubular arm; (g) locking means associated with said inner and outer tubular arms to lock said inner arm in selected relation to each; (h) trimming means having an electrical motor drive mounted on the upper end of said inner arm; (i) a conductor cord extending from said motor internally through said arms in series with said switch means and outwardly of said first handle means and terminating in a plug; (j) said conductor being a fixed expanded length equal to slightly more than the combined lengths of said inner and outer tubular arms; (k) said conductor being permanently pre-coiled into a retractable spring portion having a contracted length not greater than that of said first tubular member; (l) whereby said conductor cord is free of slack from its expanded length to its contracted length at all times and at all adjustments of said telescopic arms.
Claim 2
Dependent Claim 261 words
A telescopic cutting apparatus comprising: (a) an elongated outer tubular arm of not less than four feet in length; (b) a first handle means coaxial with and closing off the lower end of said tubular arm; (c) a biased electrical on/off switch means disposed within said handle means and being normally in the "off" position and requiring constant application of force to be translated into the "on" position. (d) a second handle means mounted proximate the upper end of said outer tubular arm; (e) adjustment means for varying the positioning of said second handle means axially and radially with respect to said outer tubular arm; (f) an inner tubular elongated arm telescopically mounted within said outer tubular arm; (g) locking means associated with said inner and outer tubular arms to lock said inner arm in selected relation to each; (h) trimming means having an electrical motor drive mounted on the upper end of said inner arm; (i) a conductor cord extending from said motor internally through said arms in series with said switch means and outwardly of said first handle means and terminating in a plug; (j) said conductor being a fixed expanded length equal to slightly more than the combined lengths of said inner and outer tubular arms; (k) said conductor being permanently pre-coiled into a retractable spring portion having a contracted length not greater than that of said first tubular member; (l) whereby said conductor cord is free of slack from its expanded length to its contracted length at all times and at all adjustments of said telescopic arms.
Claim 3
Dependent Claim 21 words
