Abstract: An axle wheel assembly is removably attached to the base of a suitcase by attaching a pair of brackets to opposite sides of the base of the suitcase. The upper edge of each bracket is provided with a downwardly extending slot. A pivotally mounted slot entrance cover is mounted on the bracket and is pivotal in one direction to cover the entrance to the slot to prevent the axle of the axle wheel assembly from falling out of the slot once the axle is inserted in the slot, and pivotal in another direction to open the entrance to the slot to permit the removal of the axle from the slot. The length of the axle is larger than the width of the suitcase so wheels of any size can be secured to the ends of the axle.

Abstract: A nut assembly comprises two end-to-end nuts threaded onto a screw and coupled by splines which prevent relative rotation between the nuts while permitting relative axial movement. A sleeve surrounds the nuts and is threaded onto one of the nuts. The other nut is formed with ratchet teeth adapted to fit into angularly spaced notches in the sleeve. When the sleeve is rotated relative to the nuts, it forces the nuts away from one another to take up backlash between the nuts and the screw. During such rotation, the teeth ratchet into and out of successive notches and ultimately prevent relative rotation between the sleeve and the nuts during normal service use.

Abstract: A linear control latch assembly controls the clutching operation of a power take-off system. A driving means produces kinetic mechanical energy which is taken off by a power take-off means. Clutch means effects a union between the driving means and the power take-off means. A linear actuator operates the clutch means. The linear actuator is controlled by a crank arm cranked into operation by a control lever. The control lever is rotated before the crank arm rotates as a result of lost motion in the control system. The initial motion of the control lever is translated into a camming action that unlatches a latch plate prior to the rotation of the crank arm. When the latch plate is unlatched, it unlatches the crank arm to allow release of the clutch that effects the union between the driving means and the power take-off means.
