Abstract
An adjustable tool supporting device for use in log and timber construction having a U-shaped frame member; a microadjustment assembly mounted to the frame member and coactive therewith to secure a timber or log therebetween; and a chain saw mounting assembly attachable to said frame member for mounting a chain saw for cutting the timber or log secured thereby and locating the saw blade for straight and angular cuts through said timer or log.
Claims10
An adjustable tool supporting device comprising a frame member;
- a micro-adjustment assembly mounted to said frame member and coactive therewith to clamp a timber therebetween;
- and a chain saw mounting assembly attached to said frame member for mounting a chain saw thereto for cutting said timber secured thereby;
- said chain saw mounting assembly having a J-shaped bracket secured to said frame member and having a hook portion extending outwardly therefrom;
- a first and second tube member secured to and disposed transversely of said J-shaped bracket member at opposite ends thereof;
- a first rod member insertable into one of said tube members;
- a base plate secured to said first rod member and extending outwardly therefrom adjacent one end thereof;
- an L-shaped member pivotally secured to said base plate;
- a Y-bracket member pivotally secured to said L-shaped member, said Y-bracket member having an upper end and a lower end and spaced axially aligned cylindrical portions adjacent said upper end;
- a saw mount plate having a rectangular body portion, a first end, a second end, means for securing a chain saw thereto and a cylindrical portion disposed adjacent said first end for axial alignment with said spaced axially aligned cylindrical portions of said Y-bracket member;
- and a second rod member axially insertable through all of said axially aligned cylindrical portions to provide a hinge pin therefor.

A device according to claim 5 in which said frame member comprises:
- a U-shaped body member having an arc portion and first and second arm portions, said arc portion having a curvilinear central portion and a first and second end portion, said central portion extending between said first end portion and said second end portion and having a shaft-receiving bore defined therethrough intermediate said first end portion and said second end portion, said first and said second arm portions extending respectively from said first and said second end portions in spaced generally parallel relationship to each other, each of said arm portions having a distal end remote from said arc portion;
- a first and a second foot member respectively secured to said distal end of said first and said second arm portions, each of said foot members having an upper part and a lower part, each of said lower parts presenting a timber-engaging surface facing said arc portion;
- and a cross beam operatively interposed between and integrally secured to said upper part of each of said foot members.
An adjustable tool supporting device comprising:
- a U-shaped frame member having an arc portion with a shaft-receiving bore defined centrally therethrough and a body portion extending between a first end and a second end, a pair of arm members, each extending from a different one of said ends of said arc portion to a distal end, a pair of foot portions, each said foot portion being secured to said distal end of a different one of said arm members and having an upper part and a lower part, each said lower part of said foot portion presenting a timber engaging surface toward said arc portion of said frame;
- a cross beam operatively interposed between and integrally secured to said upper part of each of said foot portions;
- a micro-adjustment assembly operatively interposed between said cross beam and said shaft-receiving bore and having a timber engaging plate depending therefrom for coacting with said timber engaging surfaces to secure a timber therebetween;
- and a chain saw mounting assembly secured to said frame member and having adjustment means incorporated therein to tilt the blade of a chain saw mounted thereupon and selectively cut a timber operatively positioned for cutting thereby, said chain saw mounting assembly having a J-shaped bracket secured to said frame member and having a hook portion extending outwardly therefrom;
- a first and second tube member secured to and disposed transversely of said J-shaped bracket member at opposite ends thereof;
- a first rod member insertable in one of said tube members;
- a base plate secured to said first rod member and extending outwardly therefrom adjacent one end thereof;
- an L-shaped member pivotally secured to said base plate;
- a Y-bracket member pivotally secured to said L-shaped member, said Y-bracket member having an upper end and a lower end and spaced axially aligned cylindrical portions adjacent said upper end;
- a saw mount plate having a rectangular body portion, a first end and a second end, means for securing a chain saw thereto and a cylindrical portion disposed adjacent said first end for axial alignment with said spaced axially aligned cylindrical portions of said Y-bracket member;
- and a second rod member axially insertable through all of said axially aligned cylindrical portions to provide a hinge pin therefor.
