Abstract
A foldable, hollow tubular frame, having a pair of elongated,spaced-apart legs, supports an elongated shaft rotatable on a horizontal axis at about shoulder level, with a conventional motor driven chain saw removably affixed to the shaft outside one end of the frame in cantilever position. An elongated trough extends horizontally of the frame at about waist level and the lower portion of the frame is anchored, or weighted, to avoid tipping. A control lever handle extends from the shaft alongside the saw, within the frame, so that the operator is on the chain side but out of the chain plane.
Claims10
A chain saw support comprising:
- a generally U shaped frame having a pair of elongated legs, each with a sleeve at one end rotatably supporting an elongated shaft therewithin at about shoulder level above ground level, and each with an opposite lower end having means for anchoring the same to the ground,
- log trough means supported at about waist height above ground level on said U shaped frame and extending in parallelism with said shaft to slidably support a log therein, with the end to be cut extending beyond said trough and outside one said leg;
- a power chain saw, cantilever-supported on one end of said shaft outside said one leg, and having the cutting chain thereof positioned to move in a vertical plane passing through the desired cut line of the log;
- a lever arm handle detachably affixed to said shaft for movement therewith and extending outwardly and upwardly from said shaft in the same direction as said cutting chain of said saw but at a location inwardly of said one leg to a free terminal end;
- and throttle control means at said free end of said arm connected to the throttle of said chain saw;
- whereby an operator may stand in front of said lever arm handle out of the path of said cutting chain, and lower said handle, while actuating said throttle control means, to oscillate said chain saw downwardly from the horizontal on the axis of said shaft, to cut off successive ends of a log in said trough means.
A chain saw support as specified in clain 1 wherein:
- said shaft includes a second lever arm integral therewith and extending outwardly therefrom, in a direction opposite to the direction of said first mentioned lever arm, at a location inwardly of said one leg to a free terminal end and,
- coil spring means connecting the free terminal end of said second lever arm with a portion of said log through means for biasing said chain saw into upward, horizontal nonoperating position.
A foldable, collapsible, chain saw support comprising:
- frame means having an upper portion supporting an elongated shaft for rotation on a horizontal axis at about shoulder level, an intermediate portion supporting an elongated trough, parallel to said shaft, at about waist level and a lower portion adapted to support said frame means in upstanding position relative to ground level
- a power chain saw affixed to said shaft to rotate therewith on said horizontal axis, alongside said frame means, from a horizontal position above the line of cut on a log in said trough downward in a vertical plane to a position below said line of cut
- a lever arm handle having a base end affixed to said shaft at a spaced distance from said saw, within said frame means, and extending therefrom for a substantial distance away from said shaft to permit an operator to actuate said saw without being in the path of the cutting chain of said saw;
- and throttle control means at the free terminal end of said handle, operably connected to the throttle of said chain saw, for finger tip control of the speed of said saw.
