Abstract
A log-handling device includes an elongated tubular member and a relatively longer member extending through a passage in the tubular member. Each member has a handle and a jaw, and the members are spring loaded relative to each other to urge the jaws together. The apparatus itself thus exerts the folding force on the object to be carried. The spring is adjustable so as to permit the holding force to be varied.
Claims7
A device for carrying logs and the like comprising:
- a. a first elongated rigid member including a first jaw portion;
- b. a second elongated rigid member slidably mounted on said first member for movement longitudinally thereof, said second member including a second jaw portion oriented in opposed relationship to said first jaw portion of said first member, sliding of said second member moving said second jaw portion between a first, relatively open position and a second position spaced more closely to said first jaw portion;
- c. spring means operative between engagement portions on said first and second members and biasing said second member towards the second position, said engagement portion for said spring means on at least one of said first and second elongated members being adjustable longitudinally thereof to adjust the biasing force exerted by said spring means at any relative spacing of said jaw portions;
- and
- d. an adjustable stop member mounted on one of said first and second elongated rigid members, said adjustable stop member being positionable thereon to determine the second position of said second jaw portion by engaging the other of said elongated rigid members to limit the closing movement of said second jaw portion, said adjustable stop member being adjustable in position to adjust the second position of said second jaw portion, said adjustable engagement portion being positionable to cooperate with said stop member to maintain said spring means in a pre-loaded state when said second jaw portion is in the second position thereof.
