摘要： A length extension assembly for a hand tool comprises at least two elongated extension tubings each having a longitudinal passageway and being of a size and shape that one of the tubings may be selectively inserted into the passageway of the other tubing. The assembly also includes at least two elongated extension bars each of a size and shape that each extension bar may be inserted into an appropriate tubing. The tubings are provided with longitudinally spaced locking holes. Each bar is provided with a locking member which can enter and be engaged in one of the locking holes to connect the bar to its tubing. Optionally, one tubing could be inserted into the larger tubing and a locking member on the smaller tubing could be engaged in a locking hole of the larger tubing to connect the tubings together. Various length selections can be achieved by connecting a bar to at least one tubing or by connecting a bar to one tubing and connecting that tubing to a larger tubing. Additional length adjustment is achieved by the engagement of a locking member in an appropriate locking hole.

摘要： A non-rotatable valve lifter mechanism for use in an internal combustion engine includes a rotatable cam shaft having at least one confinement member disposed on the cam shaft adjacent to its cam lobe. The valve lifter includes a follower and includes at least one abutment member in surface to surface contact with the confinement member to prevent rotation of the valve lifter. Preferably confinement and abutment members are on each side of the cam lobe and roller follower.
