Abstract
A log positioning and securing device is described in which a frame supports a log receiving trough with sides positioned to receive and support a log along a longitudinal plane. A log clamp including a pair of log clamp members is movably mounted to the frame. The clamp members are driven to move between an inoperative position in which the log clamp members are separated in a log receiving position, and a log clamping position in which the log clamp members are moved toward one another and toward the longitudinal plane, to clamp and hold a log securely along the rough, with the centerline of the log parallel to or coincidental with the plane.
Claims18
A log positioning and securing device, comprising:
- a frame;
- a log receiving trough on the frame including trough sides positioned to receive and support a log along a longitudinal plane;
- a log clamp including a pair of log clamp members movably mounted to the frame;
- wherein the log clamp members are driven to move between an inoperative position in which the log clamp members are separated to opposite sides of the longitudinal plane in a log receiving position, and a log clamping position in which the log clamp members are moved toward one another and toward the longitudinal plane;
- wherein the log clamp members include upward ends that are spaced apart from one another in the log clamping position;
- and
- a linkage connecting the frame and clamp members and operable to move the clamp members toward the trough such that a log engaged by the clamp members is pulled against the trough.
A log positioning and securing device, comprising;
- a stationary frame;
- an elongated log receiving trough on the frame including downwardly converging trough sides positioned to receive and substantially center a log along a longitudinal plane;
- at least two log clamps, each including a pair of log clamp members mounted to the frame and moveable between an inoperative position in which the log clamp members are situated at a first elevation, and an operative position below the first elevation in which the log clamp members form substantially semi-circular arcs with a center positioned at least approximately adjacent to the longitudinal plane, such that a log clamped by the log clamp members is pulled against the trough sides;
- and
- the semi-circular arcs being sized such that in the operative position the log clamp members are spaced apart to opposed sides of the longitudinal plane such that the log is gripped on opposite sides and a top portion of the log is exposed elevationally;
- and
- a clamp actuator interconnected between the frame and log clamp members and operable to forcibly shift the clamp members between the inoperative and operative positions.
A log positioning and securing device, comprising;
- a frame;
- a log receiving trough on the frame including trough sides positioned to receive and support a log along a longitudinal plane;
- a log clamp including a pair of log clamp members mounted to the frame for elevational movement;
- wherein the log clamp members are driven to move between an inoperative upper position in which the log clamp members are separated in a log receiving orientation, and an operative lower position in which the log clamp members clamp the log in a substantially centered relation to the longitudinal plane;
- a log ejector mounted to the frame and positioned on the frame for movement in are arcuate direction for relation to the trough between a first position below the trough and a second position above the first position;
- and
- whereby a log on the trough may be lifted by the ejector and moved laterally with respect to the longitudinal plane and over the log clamp members.
