Abstract: A roller unit for use as a caster for luggage, for example, has a sturdy -piece roller housing formed of sheet metal, the housing comprising a rectangular base with raised pads at opposite ends thereof and a roller-receiving shell defined by a pair of opposed U-shaped walls bent from opposite longitudinal edge regions of the base between the pads. Roller units are manufactured seriatim by metal forming operations that do not require deep-drawing.

Abstract: A drawbolt for the mating shells of a container has a latch whose spaced e walls are provided with open slots that receive a transverse cross-bar on one end of a loop whose other end is engageable behind a hasp on one of the shells. Outwardly directed lugs on the side walls are received in aligned apertures in spaced guide walls of a frame, such walls having edges defining aligned peripheral cam surfaces which, together with the closed end of the slots in the latch, capture the cross-bar of the loop and establish a pivotal connection between the latch and the loop. By attaching the frame to a plate adapted to be mounted on the other of the shells, the apertures in the guide walls are closed by the plate. The free ends of a pair of upstanding tabs on the plate cooperate with the closed ends of the apertures in capturing the lugs on the latch thus establishing a pivotal connection between the latch and the frame.

Abstract: A latching device for releasibly locking together the two zipper pulls on a ouble zipper type case includes a frame, a rotatable key barrel projecting from the frame for being received in respective openings in the zipper pulls, a latch member pivotally connected to the frame for movement between a lowered position overlying the frame and a raised position, the latch member having an opening therein for receiving the end of the key barrel when the latch member is in lowered position, and a key-actuatable bolt member supported below the key barrel for sliding movement between the locking and unlocking positions to releasibly lock the latch member in lowered position. The frame is mounted at one end of an elongated mounting plate having its other end constructed to engage a rigid reinforcing member of the case.

Abstract: In a latching device having a first push member to be depressed to releasy engage a hasp and a second push member cooperable with the first push member to be depressed to release the hasp, the cooperable parts of the push members comprise flat plate portions which are disposed in and movable in the same plane.

Abstract: A combination lock, including a plurality of dials and associated sleeve ns for each dial, has a plug member which is longitudinally movable to first and second positions and which is cooperable with the sleeve means for being locked in the first position when the dials are off combination. A manually operable latch member formed to engage a hasp is longitudinally movable from a latching position to an unlatching position only when the plug member is not locked in the first position. Longitudinally movable pullers are provided for moving the latch member from latching to unlatching position and from unlatching to latching position, respectively.

Abstract: The cradle selector controls of a motorized rotary-type file comprise a row f simple, momentary-type pushbutton switches located in a small housing mounted so as to slide along the rear edge of the operator's shelf. The control housing is connected to the file where all other controls are located by an electrical cable, whereby the selector controls can be readily moved back and forth with the operator.
