KNOB ATTACHMENT.
SPECIFICATION forming part of Letters Patent No. 546,970, dated September 24, 1895.
Application filed December '7, 1893. fierial No. 492,999. (No model.)
To all whom, it may concern.-
Be it known that 1, CHARLES F. DOEBLER, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Knob Attachments, of which the following is a specification.
The invention relates to the class of adjustable screwless knob attachments; and the object is to provide a simple and cheap adjust ment of this class which can be easily and quickly set by any one on doors of varying thickness with the knobs a correct distance apart and most securely held against accidental removal.
Referring to the accompanying drawings, Figure l is aside view of apair of knobs held tog-ether by this improved attachment. Fig. 2 is a section of one of the knobs to show the arrangement of the attachment; and Fig. 3 is a view of the inner face of the knob illustrated in Fig. 2, showing the spindle in cross-section.
The knobs may be formed of any common material in the most approved patterns, and of those illustrated the knob 1 is secured to the spindle permanently by any common method, while the knob 2 is secured to the spindle by means of the improved adjustable attachment. The spindle 3, which is of the usual size and shape, is split for a certain distance at one end, and is provided at that end with a wedge-receiving groove 4, and is preferably V-shaped. The hub 5 of the knob 2 has a socket adapted to receive the split end of the spindle, one wall of which socket is inclined, as at 6, while the exterior of the hub is provided with a screw-thread. Fitting and moving on a spindle is a sleeve 7, that preferably has a squared portion by means of which a wrench may be applied, and which has an interior thread that fits andis adapted to be screwed upon the exterior thread on the hub 5 of the knob 2. Connected with this sleeve 7 is a latch 8, thatis \I-shaped in crosssection so as to fit into the V-shaped groove of the split end of the spindle, and one face of this latch is inclined or beveled, so that when the sleeve is screwed up on the hub of the knob 2, this inclined portion Will make contact with and be forced downward by the inclined Wall of the socket in the hub. This latch 8 is preferably held by a pivot 9 to a collar 10, that is free to turn or that is loosely held in the sleeve, which collar preferably has a flanged or shoulder part 11, that is adapted to be engaged by a portion of the sleeve,so as to be held from longitudinal movement. The sleeve 7,with this collar-bearing latch, is slipped upon the spindle and then the spindle and end of the latch are thrust into the socket in the hub of the adjustable knob, and as the sleeve is screwed up when the knob has been adjusted to the desired position, the contact of the inclined faces of the latch and the wall of the socket forces the wedge-faces of the latch into the \I-shaped groove, so as to thrust apart the split ends of the spindle and cause them to bite tightly against the walls of the socket, then the knob cannot be pulled from the spindle until the sleeve is unscrewed, so as to release the latch-wedge. By means of this construction a very simple attachmentis provided which cannot be put together in any way but in the correct manner, for the split ends of the spindle cannot be thrust through the sleeve and into the knob without the V-shaped latch is in the \i-shaped groove, (see Fig. 3,) and when the sleeve is screwed up such a very firm, powerful wedge is provided for the split ends of the spindle that the knob cannot be accidentally removed.
I claim as my invention- In combination with the threaded hub of a knob, a spindle that is longitudinally divided by a V-shaped slit and is adapted to pass into an opening in the knob hub, the end of said opening having a portion of one wall outwardly inclined, a collar longitudinally movable on said spindle, a triangularly shaped latch increasing in thickness from one end backward, a perforation passing through a portion of the latch near its thicker end, a pivot pin passing through the collar and the perforation in the latch, a sleeve screwing on the threaded hub of the knob and having a shoulderthat bears against the collar whereby when the sleeve is screwed upon the hub the collar is pushed inward and the latch caused to oscillate on its pivot and expand the separated parts of the spindle, substantially as specified.
CHARLES F. DOEBLER.
