    Abstract: An automatic height and angle adjusting swivel glide for use on furniture, such as tables, chairs, etc., or other equipment, having an upper and a lower shell or housing part secured together, a multisectioned collet within the assembled shells resiliently held together by means of an elastic ring, and a cam with a stem for securing to the furniture or equipment. The collet is provided with opposed concave generally conical surfaces receiving a cam surface on the lower end of the stem and a second cam surface on the raised central portion of the lower floor-engaging shell. Interaction between the cam surfaces and the collet allows the glide to rise, lower and tilt relative to the stem and compensate for irregularities of the floor surface.

    Abstract: HINGE CONSTRUCTION FOR THE DOORS OF CABINETS OR OTHER ENCLOSURES WHERE THE DOOR IS MOUNTED TO SWING BETWEEN OPEN AND CLOSED POSITIONS, WITH THE HINGE HAVING A DOOR WING AND A CABINET WING. THE DOOR WING IS A CONFIGURATION FOR EITHER AN INSET OR AN OVERLAY TYPE OF DOOR, AND THE CABINET WING IS EITHER EXPOSED OR PARTIALLY CONCEALED. ONE TYPE OF CABINET WING INCLUDES A GENERALLY U-SHAPED FLANGE THAT FITS AROUND AND CLAMPS ONTO THE EDGE OF THE CABINET FRAME WITH ONLY A SINGLE SCREW REQUIRED TO SECURE THE WING TO THE FRAME. THE CABINET AND DOOR WINGS MAY INCLUDE A SELF-CLOSING MECHANISM HAVING A HOUSING SECURED TO OR INTEGRAL WITH THE CABINET WING, THE HOUSING CONTAINING A SPRING-BIASED CALM THAT IS URGED OUTWARDLY TO ENGAGE THE KNUCKLE OF THE DOOR WING, AND A HINGE PIN OR PINTLE DEFINING THE AXIS OF THE DOOR. THE DOOR WING KNUCKLE INCLUDES A CUT-OUT PORTION COOPERATING WITH THE CAM TO URGE THE DOOR THROUGH THE LAST FEW DEGREES OF THE ARC OF CLOSING MOVEMENT AND YIELDABLY RETAIN THE DOOR CLOSED.

    Abstract: A dead bolt lock for use on the interior surface of a door for the entrance of a home or other building adapted for actuation by an exterior tumbler lock or an interior knob, where the dead bolt is projected into a strike or retracted into the lock housing. The lock assembly includes a dead bolt having a pair of rearwardly extending arms, a rotatable knob and a flat spring positioning the knob in either the projected or retracted position of the bolt. The knob includes an internal flange having a camming pin cooperating with a camming surface at the rear end of one bolt arm to reciprocate the bolt and a spaced blocking cam which is moved into a blocking notch formed in the other dead bolt arm when the bolt is projected.

    Abstract: A latching mechanism between adjacent panels of a sectional cabinet or building construction where a pair of opposing latch housings are imbedded in the facing edges of the panels with one housing containing a rotatable latch bolt and the opposite housing containing a transverse latch pin or strike cooperating with the hook end of the bolt. The bolt structure includes a generally circular body with an offset and outwardly extending arm terminating in a latching hook and has a central circular opening for a rotating cam. The cam has an offset hub or shaft received in aligned bearings in the housing, a tab extending from one flat surface cooperating with projections on the bolt body, and spring means retaining the cam within the opening in the bolt.
