Abstract: This is an accessory for a two wheeled trailer composed basically of three parts for each wheel: a wheelpiece that fastens to the outside of the wheel and that contains in its center a hexrod; a long-handled ratchet that fits in place over the hexrod of the wheelpiece and that contains a long wooden handle which can be taken in hand to rotate the wheel, tied to the trailer frame, or left on the ground to prevent backwards rotation of the wheel in relation to the ground or the trailer frame; and, a mechanical brake that also fits in place over the hexrod of the wheelpiece to control motion and to use in conjunction with the long-handled ratchet for leverage. This invention enables a single individual to easily move a heavily loaded two wheeled trailer over difficult terrain, such as a two wheeled boat trailer on a beach, if one or several techniques are used for leverage and control.

Abstract: A no-lash telescoping steering shaft (10) comprises first and second telescopically arranged parts (12, 18) which are configured to transmit torque therebetween. The first and second parts carry an axially and radially movable locking piece (68) engaging the first and second parts at points which are axially spaced apart.
