Abstract: A knob catch for securing a knob or lever to the driving spindle of a door lock. The knob catch is constructed of a base with a centered odd shaped hole. The hole is made in such a way that the knob or lever cannot be removed when the locking device is in the locked position using a key operated cylinder with a flat locking bar. A tongue portion of the knob catch rises above the base and fits into the knob or lever and keeps the knob or lever from being removed. In the front side of this tongue is an angular surface which permits the knob or lever to be slid over the top of the knob catch until the knob catch tongue and an aperture in the knob or lever align allowing the tongue to be spring biased into the aperture to secure the knob or lever. There are two springs attached to the knob catch to bias the tongue into engagement with the knob or lever aperture.

Abstract: An inside door handle assembly includes a handle rotatably held on a base to be secured to a vehicle's door and a knob rotatably held on the base.

The block also serves as a spring, biasing the retaining plate toward the groove.

Abstract: A drive element in this lock pushes a radially directed outward finger out of its longitudinal slot in the outer tubular spindle to disengage the outer handle from the latch so that the handle free-wheels. Spring means in the outer handle rose returns the handle to its normal horizontal position when the handle is released. The handle is preferably in lever form.

Abstract: The support member underlying the door outer panel has coaxially aligned apertures formed in spaced apart walls thereof. First and second telescopically engaged axle members molded of plastic have integral axle spindles projecting from the ends thereof. A spring acts between the axle members to permit axial contraction of the axle members relative one another so that the axle spindles may be inserted between the spaced apart aperture panel walls. The spring then functions to extend the axle members axially apart to position the axle spindles within the panel apertures and thereby rotatably mount the axle members on the panel.

Abstract: The arrangement comprises a standard, door knob-operated, latch mechanism in which the cylindrical shank of the door knob is slidably engaged with the rotatable spindle of the mechanism, and the spindle has a spring-biased catch projecting therethrough which passes into a slot formed in the cylindrical shank of the knob. In this way, the knob is secured on the shank. The improvement comprises forming a ramp in a cut-out on the terminal or outermost end of of the cylindrical shank, and forming a complimentary bevel on a corner of the projecting catch. Accordingly, when the knob is slidably forced onto its spindle, during manufacturing assembly, the ramp formed in the cut-out engages the bevel and, consequently, depresses the catch to allow the cylindrical shank to slide thereupon and thereover, and to allow the catch latchingly to engage the slot.

An attachment screw is employed to secure the stem adapter to the valve stem. The handle adapter has a multiplicity of resilient finger members with terminal portions adapted to engage both the angled shoulder surface and the undercut portion of the stem adapter. A handle member of a generally U-shaped configuration has a retainer member secured therein with the retainer member having finger engaging portions.

Abstract: A door lock mechanism in which the outside knob is seamed against knob retainer, the retainer is diametrically slidable in the knob sleeve and has a specially shaped opening which defines a thrust-receiving edge for engagement by a spring which straddles a central area of the opening, and which has side borders which project toward each other and define blocker engaging surfaces between the legs of the spring. In a cylinder lock, a blocker plunger is preferably carried by a standard type bushing slidable in a standard supplemental cam sleeve, and the plunger is supported close to the retainer by the end wall of such cam sleeve. In a mortise lock, the plunger is similarly supported close to the retainer by a bushing in the knob sleeve.

Abstract: One of two frame elements to be removably connected is telescoped over and removably latchably secured to the intervening connector structure. The removable latching means takes the form of a cantilever mounted spring component located internally of the connector structure hollow body component, the spring resilient forward portion including a locking projection upwardly urged through an apertured wall of the body component and into a registering-aperture of the telescoped frame element. The cantilever spring is of novel structural and internally mounted relationship with the hollow body component to prevent longitudinal slidable movement of the spring and to ensure that it will reliably, though yieldably, upwardly urge the locking projection through the apertured wall and into the registering-aperture of the frame element to be removably latchably secured.

The spring has a central angular bight embracing a central tongue on the retainer plate at one side of the sleeve, and side legs straddling a central clearance space in the knob sleeve and extending into stressed camming engagement with converging inside faces of the opposite half of the sleeve. The spring legs may have end portions interlocked with the plate to secure the spring in place, or may be otherwise retained.

Abstract: A door lock for use on a door panel has bores containing a lock mechanism including a chassis on which spindles are mounted for rotation about two parallel axes. Door handles or other lock operators are disposed on opposite ends of both spindles and are interconnected variously to operate a lock bolt and a latch bolt. The lock and latch bolts are also disposed in the bores and are joined to the chassis.

Abstract: A door knob is machined from solid stock to provide a tubular neck, an intermediate portion which is internally recessed to reduce its wall thickness, and a solid-section end portion having a large axial end opening which provides tool access for recessing the mid-portion and clears the pin tumbler lobe of a key-removable core mounted in the knob sleeve with its key plug concentric with the knob. The end opening has an axially-outward facing shoulder and an adjacent radially-inward opening groove. A knob locating, bevelled-edge ring lies against the shoulder with its edge partially closing the mouth of the groove. An end face member having a peripheral bevelled skirt is pressed into the end opening and against the edge of the ring so as to deform the skirt outward into the groove and thereby secure both the end face member and the ring in the knob. The end face member may have an opening for a core mounted in the knob sleeve, or for other usual knob accessories, or may completely close the end of the knob.

Abstract: A heavy duty cylindrical lock set adaptable for various "functions" and having improved features, especially to permit a key-removable lock core to be reversible in its knob mounting to suit right- and left-hand doors. A knob sleeve of large diameter is slotted and shaped at its knob receiving end to form two diametrically-opposed channel sections of high strength and rigidity. The inward edges of the four channel side legs form a mounting seat to receive the key-plug-containing body of the core on the axis of the knob, while the two spaces between the channel sections permit the pin-tumbler lobe or section of the core to extend radially in either of two orientations about the axis of the knob. Two of the channel side edges are notched to engage a key-controlled retaining lug of the core. The knob has a large bore in its outer end and is supported from the knob sleeve by a drive ring which accomodates the core in both orientations. A face plate is held in the knob bore by the core and closes the knob bore.
