Abstract: A guard mount structure for a dead bolt installation on a door has a preassembled condition wherein a dead bolt subassembly consisting of a housing and a dead bolt shaft is attached to a sheet metal guard. The sheet metal guard has opposite plates for attachment to opposite faces of the door and an end plate overlying the end face of the door, the housing of the dead bolt subassembly being attached to the inside face of the end plate.

Abstract: The wheel hub cover has a series of slots around the edge moulded into inner (110) and outer tags (100), between which metal insert clips (30) are gripped. The clips have a re-entrant shape with stamped retaining lips (80) which grip grooves in the wheel disc. They are held in the grooves by moulding over holes through their base support strips. The clips and cover are suitable for low cost mass production. The clips are firmly held in the moulding with thesecuring lips braced on the cover by moulded ribs (150). No special tools are required for fitting the covers.

Abstract: For translating the linear motion of a pivotally mounted thumb piece for a front door latch into the rotary motion needed to withdraw a latch bolt, two rotary members are employed. One is a bell crank having a pivotal mounting on the mounting plate at one side of and at right angles to the pivotal mounting of the thumb plate and rotationally responsive to linear motion of the thumb piece. The other is a drum having a rotatable mounting on the mounting plate parallel to and spaced from the bell crank pivotal mounting, and at a location adjacent a roll back of a latch bolt. A resilient connector strip from the bell crank to the drum causes the drum to be rotated in response to rotation of the bell crank. A torsion return spring attached to the drum acts to return the drum and the bell crank to their original positions.

Abstract: The invention involves a mechanism for simultaneously retracting two separate latch bolts which have previously been extended by their individual separate mechanisms. The individual mechanisms comprise a substantially conventional knob actuated latch bolt, and what is commonly called a locking dead bolt. There is a lever arm attached to the knob spindle and a bell crank arm on a thumb turn shaft of the dead bolt. A flexible strip anchored at one end to the free end of the lever arm projects slidably through a swivelling sleeve on the free end of the bell crank. By providing a stop at the extremity of the strip by rotation of the knob spindle and its lever arm the bell crank is induced to rotate and withdraw the dead bolt to unlocked position, at the same time that the latch bolt is withdrawn to open the door. Conversely, when the dead bolt only is withdrawn, by rotation of the thumb turn shaft merely to unlock the door, the strip will slide through the swivelling sleeve. The lever arm of the knob spindle remains undisturbed and the latch bolt, therefore, remains in extended position, holding the door closed until withdrawn by knob action.

Abstract: PLASTIC DOOR LOCK A plastic door lock, sometimes referred to as a door latch, makes use of moldable plastic material for most of the individual parts of the lock assembly with opposite roses adapted to interlock with each other and be held together with a single screw on the axial center line of the knobs and accessible from the outside. When used as a privacy lock unlocking the lock from the outside is prevented by pushing the inside knob into a releasble but nonrotatable engagement with the inside rose. A lost motion connection between the latch bolt and roll back spindle allows the door to be closed without damage to the latch bolt when the inside knob is locked. Inherent resiliency in the material of the latch bolt case, in cooperation with the movable latch bolt, releasably returns and holds the latch bolt in extended position.
