in fig1 i describe one embodiment of a tree trimmer device 10 , generally , according to my invention . in the elevational view of fig1 i describe the tree trimmer 10 as having housing members 12 , 14 , and 16 fitted together in a retracted condition , as it would be considered in its most convenient position for ease of handling or easy storage . the tree trimmer device 10 includes a cutting component 38 , generally , positioned securely upon an upper , or distal , end of the trimmer , thus positioned upon housing member 12 . fig1 also shows one manner in which the housing members 12 , 14 , and 16 are held in position by clamping members . a first clamping member 20 , generally , includes a securing band 22 around housing member 14 and held in suitable adjustment and security by means of a thumb screw 24 . housing member 14 may be suitably positioned within housing member 16 , and held securely therein , by means of a second clamping member , 26 , generally , which includes a securing band 28 around housing member 16 and held in position by a thumb screw 30 . for storage , or easy transportation , the tree trimmer may be easily handled by loosening of thumb screws 24 and 30 and retraction of housing members 12 and 14 into housing member 16 . then , for operation , the housing members may be suitably adjusted and secured into position as preferred by the operator . a handle member 32 , generally , comprises a securing band 34 securable into comfortable position by adjustment of a screw - type handle member 36 , adjustable by the operator . as i have described above , and now show specifically , in fig1 and 2 , i have designed a tree trimmer which is safe , convenient , and easy to use , because i have eliminated undue interference which is commonly noted in extendible tree trimming devices , which is particularly encountered because of components of such devices which extend substantially radially from a tubular component . the method of handling is made easier because more attention may be given to the maneuvering of the tree trimming device and less attention need be given to loose exterior components . my tree trimmer device 10 includes a pruning component 38 , generally , positioned at the distal end of the trimmer , and which includes a stationary cutting member 40 attached to a support member 42 by any suitable means of attachment , such as a screw 44 . the pruning component 38 includes a movable cutting member 46 which has a sharp cutting surface 48 . cutting member 46 is movably secured to the stationary cutting member 40 by means of a pin 50 . then , for cutting operation , movable cutting member 46 is operatively connected by means of a pin 52 to a flat bar member 54 , which , in turn , is connected by pin 56 to a gear component 58 , which is operatively positionable against driving gear 60 . driving gear 60 is positioned on shaft 62 connected to a conventional clutch component 64 , generally , of a type of clutch conventionally used for power equipment to permit safe and protective operation . the clutch component 64 provides the means for quickly and safely disconnecting the cutting components from typical electric motor 66 should there be a sudden interference of the cutting action by any sudden overload of the motor , as when the cutting member encounters a branch which might be too difficult to cut , or if the tree trimmer should encounter some other impenetrable object . motor 66 is of a type commonly adaptable for use in the usual domestic type appliance or equipment , readily operable through the use of a safe extension cord . a most important feature of the tree trimmer device 10 is the use of a coiled cable wire 68 , shown in fig2 in a retracted condition , when the housing members 12 , 14 , and 16 are in a retracted condition ; and shown in fig3 and 6 in an extended condition when the housing member 12 , 14 , and 16 are in an extended condition . at its upper end , wires of the cable 68 are attached to motor 66 , and at its lower end , wires of cable 68 are attached to a switch member 70 . the tree trimmer devices described in fig1 , and 3 show the switch member 70 connected by lines 72a and 72b to extension cord 74 . in fig6 lines 72a and 72b connect switch member 70 to a battery component ( not shown ) within the lower end of lower housing member 16 . fig6 describes a slightly modified power transfer component for the cutting mechanism . the means for transferring power from the gear component 58 to the movable cutting member 46 comprises a flat bar member 76 , generally , which includes a slotted end member 78 enclosing pin 56 attached to gear 58 , thus displaying another well - known form of power transmission . as i show in fig4 the gear mechanism 58 is secured upon a shaft component 80 which is held rotatably and supportably within a bushing component 82 secured against the inner wall of upper housing member 12 . since many different embodiments of my invention may be made without departing from the spirit and scope thereof , it is to be understood that the specific embodiments described in detail herein are not to be taken in a limiting sense , since the scope of the invention is best defined by the appended claims .
a portable tree trimming device comprising a pruning mechanism secured at a distal end of a telescopically extendible housing . the pruning mechanism includes cutting members exterior of the housing drivable by a motor within the housing . the motor receives current furnished thru a coiled cable within the housing receiving power from either a domestic electric source or from a battery unit positioned within the housing . the coiled cable extends and protracts in unison with extension and protraction of the extendible housing .
