The wire lock is provided for holding a stop ring on the outer surface of a cylinder. The stop ring includes a counterbore at one end thereof. The counterbore is positioned above an annular groove in the outer circumference of the cylinder. The wire lock is inserted into the registered counterbore and annular groove so as to prevent the stop ring from moving axially on the outer surface of the cylinder. The wire lock is accessible and visible from one axial end of the stop ring.

The double acting hydraulic piston and cylinder assembly of the present invention utilizes a unique fastening mechanism for fastening the piston to the cylinder rod. The piston has a rod receiving opening through which the piston rod is fitted. The piston includes a piston groove which is aligned with an annular rod groove in the outer surface of the rod. Extending from the outer circumference of the piston inwardly to the piston groove is an access opening, through which a retaining wire is inserted. The retaining wire is wrapped around the piston rod and fits within both the piston groove and the rod groove so as to hold the piston against longitudinal movement with respect to the rod. The method of the present invention comprises inserting the retainer wire through the access opening in the piston and rotating the piston until the wire wraps around the piston rod.

Piston locking device for double acting hydraulic cylinder

A shoe box is disclosed for safely and temporarily holding shoes of a hotel guest on the outside of a hotel room door so that the shoes can be picked up, shined and returned and which does not require that the hotel guest have a key to open the shoe box. The box is substantially rectangularly shaped and includes a top wall, a bottom wall and a pair of side walls. The back of the box includes a border around the perimeter defining an opening for insertion and removal of the shoes by the guest when the box is removed from the door. A hinged cover including a lock can only be opened by an attendant for removing the shoes for polishing or for replacing them. The top rear of the box carries a bracket which fits over the top of a door to suspend the box thereon with the back of the box flush against the door. Cushing material on the back of the box and on the inside of the cover reduce the noise which would otherwise be created when the box was being hung on the door or when the cover was being closed.
