Abstract: A cart for carrying a cut-off saw having a saw blade. The cart includes a frame with upper and lower portions, a wheel arm pivotably coupled to the lower portion about a first axis, and a rear wheel assembly coaxial with the first axis and coupled to the frame and the wheel arm. The cart includes a front wheel coupled to an end of the wheel arm opposite the rear wheel assembly, an adjustment lever pivotably coupled to the upper portion about a second axis, and a link having a first end pivotably coupled to the adjustment lever and spaced from the second axis, and a second end pivotably coupled to the wheel arm between the first axis and the front wheel. Pivoting the adjustment lever about the second axis pivots the wheel arm about the first axis to adjust a vertical position of the front wheel relative to the upper portion.

Abstract: A clutch mechanism is used in a rotary power tool having a motor. The clutch mechanism includes an input member to which torque from the motor is transferred and an output member co-rotatable with the input member. The output member defines a rotational axis. A cam surface is formed on one of the input member or the output member. First and second compression springs are carried by the other of the input member or the output member for co-rotation therewith. A follower has a circular cross-sectional shape and is biased against the cam surface by the first and second compression springs. In response to relative rotation between the input member and the output member, the cam surface displaces the follower along a line of action coaxial or parallel with each of the first and second compression springs. The line of action does not intersect the rotational axis.
