Abstract
Apparatus is disclosed for extending the reach of a portable chain saw for the purpose of cutting tree limbs and branches which would otherwise be inaccessable to the operator of the saw. An elongated post which can be held in the hands is equipped with means for securing a chain saw thereto at the front end. A pivotable lever is also attached to the front end of the post for contacting and depressing the power trigger on the chain saw. A finger operated control trigger is located at the rear end of the post, and means are provided for connecting the pivotable lever and the control trigger so that the lever is pivoted and the power trigger of the saw is thus depressed by the lever when the control trigger is operated.
Claims11
The combination of a chain saw and an apparatus for hand-holding and controlling same while extending the reach of the saw comprising:
- a. a post which can be held in the hands and which includes means at the front of said post to which end said chain saw is secured;
- b. saw actuating means comprising a pivotal lever attached to said post toward the front end thereof;
- c. a control trigger attached to said post rearwardly of said actuating means;
- d. a flexible cable operably connecting said actuating means and said control trigger;
- e. a chain saw cutting chain projecting forwardly of said post in orientation with the longitudinal axis thereof;
- and
- f. a chain saw power trigger selectively engaged by said actuating means whereby depression of said control trigger depresses said power trigger.
The combination of a chain saw and an apparatus for handholding and controlling same while extending the reach of the saw comprising:
- a. a post which can be held in the hands and which includes means at the front end of said post to which said chain saw is secured;
- b. saw actuating means associated with said post toward the front end thereof;
- c. a control trigger attached to said post rearwardly of said actuating means;
- d. a flexible line having one end attached to said actuating means and the other end of said line attached to said control trigger;
- e. a chain saw cutting chain projecting forwardly of said post in orientation with the longitudinal axis thereof;
- and
- f. a chain saw power trigger selectively engaged by said actuating means whereby depression of said control trigger depresses said power trigger.
An apparatus for holding, controlling and extending the reach of a chain saw, said saw including a cutting chain, a selfcontained motor, a motor housing, a pistol grip handle with a power trigger and a grasping bar, and said apparatus comprising:
- a. a post including first and second ends;
- said second end being adapted for human grasping;
- b. means for removably attached said chain saw to said post first end, said cutting chain being disposed forwardly of said first end, said last named means comprising:
- 1. a platform attached to said post at the first end thereof, adapted for receiving said motor housing thereon;
- 2. means disposed at a forward portion of said platform for releasably clamping a lower lateral portion of said grasping bar to said platform;
- 3. means for releasably clamping a rearward portion of said motor housing to a rearward portion of said platform;
- c. mechanical actuating means disposed adjacent said first end;
- a portion of said actuating means adapted for engagingly manipulating said power trigger, for controlling said motor;
- d. control means attached to said post rearwardly of said actuating means for remotely operating said actuating means;
- and
- e. a flexible line having one end attached to said control means and the other end attached to said actuating means such that manipulation of said control means controls said chain saw motor through displacement of said actuating means and power trigger.
