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.Type: GrantFiled: April 16, 1976Date of Patent: October 11, 1977Assignee: Best Lock CorporationInventors: Walter E.

Patent number: 3955387Abstract: 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.Type: GrantFiled: November 14, 1974Date of Patent: May 11, 1976Assignee: Best Lock CorporationInventors: Walter E. Best, R.

Patent number: 3934437Abstract: In a door bolt lock a tubular housing extends through a bore in the door near the edge thereof for housing at least one lock cylinder assembly coupled in mechanical operative association with a lock bolt assembly passing from the edge of the door into the tubular housing via an intersecting bore in the door. The tubular housing includes first and second axially separable coaxially aligned portions having flanges on their outer ends for capturing the door therebetween. The first and second tubular housing portions are threadably coupled together either directly or via a threaded insert, whereby the length of the housing is adjustable for accommodating doors of various thicknesses and whereby the two halves of the lock cylinder housing are coupled together by means of a relatively strong threaded tubular structure to make it more difficult to break apart the two halves of the housing.Type: GrantFiled: December 12, 1974Date of Patent: January 27, 1976Assignees: Alois Crepinsek, Lee A.
