DOOR KNOB CONSTRUCTION Filed Sept. 3. 1930 Patented Nov. 10, 1931 UNITED STATES NATHANIEL B. STONE, OF WASHINGTON, DISTRICT OF COLUMBIA V DOORKNOB ooivs'rnoo rron Application filed. September a, 1930. Serial No. 479,547
This invention relates to door knob construction, the primary object of the invention being to provide means'for securing door knobs to their shanks in such a way as to insure against wear between the knobs and their shanks, to the end that the knobs will be held securely against movement on their shanks.
An important object of the invention is to provide means for securing knobs on their shanks by frictional contact between the knobs and shanks, the construction of the se-' curing means being such as to eliminate the use of the usual securing screws.
A further object of the invention is the provision of adjustable securing means whereby the knobs may be moved into close engagement with the door to insure a close fit between the door knobs and door.
\Vith the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts andin the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may bemade within the scope of what is claimed, without departing from the spirit of the invention.
Referring to the drawings:
Figure 1 is a sectional View through'a door knob secured to its shank, by a securing means constructed in accordance with the invention.
Figure 2 is an elevational View of a knob, the outer section thereof having been removed. 7
Figure 3 is a sectional view taken on line 33 of Figure 1.
Figure 4 is a perspective view of the wedge shaped key, forming a part of the securing device.
Referring to the drawings in detail, the reference character 5 designates a door knob shank to which the knob, indicated generally by the reference character 6, is secured.
The knob 6 comprises an inner section 7 and an outer or cover section 8, the inner section 7 being provided with an extension 9 formed with a square opening to receive the square shank 5. a
. 'As shown, the opening of the'extension 9 is formed with an offset enlarged portion, one Wall thereof being inclined as at 10, the inclined wall being provided to cooperate with the wedgeshaped keyll. The side 5 Walls of the offset enlarged portion of the opening of the extension 9, are formed with longitudinal grooves to accommodate .the ribs 7 12 that extend from the'side edges ofthe V wedge shaped key, so that the key Will be held 0 in position at all times so that when the knob is slid over the shank, thekey .will be in a position to grip the shank.
:Extending from one end of the key 11, is a finger 13 that is adapted to contact with the o5 door knob to prevent the key from being-extended toofar into the opening, in which the key is positioned. This finger 13 also lies opposite to the opening 14: to be engaged by a tool inserted in the opening, so that the key 11 may be moved inwardly, causing it to disengage" the shank 5, to the end that the door knob may be released from the door knob shank. v
i The reference .character l5 designates a groove formedin one end of the key, which groove provides a. seat for one end ofthe spring 16 which is coiled'to fit within the door knob.
From the foregoing it will be seen that due to the construction shown and described, a door knob constructed in accordance with the invention, may be. slid into position on the shank, the wedge shaped key gripping the shank to hold the knob in position.
It might befurther stated that the shank engaging surface of the key is roughened as at 18, to cause the key to bite into the shank and securely hold the knob in position. a
I claim: I V
1. In a door knob securing device, a door knob shank, a door knob having an opening to receive the shank, said opening having an enlarged offset portion formed with grooves,
a key fitted Within the offset portion, ribs 100 on the key to fit within the grooves to hold the key Within the opening, and means within the knob and engaging the key for forcing the key into close engagement with the knob 5 and shank.
2. In a door knob securing device, a door knob shank, a door knob mounted on the shank, a wedge shaped member disposed between the knob and the shank to frictionally engage the knob and shank to secure the knob on the shank, said wedge's'haped member having a groove in one end thereof, a, spring fitted within the knob and having one end thereof disposed within the'groove, and
said spring adapted to move the wedge shaped member longitudinally of the shank to set up a binding action between the knob and shank. r
3. In a door knob securing device, a door as knob shank, a knob comprising an inner section' and an outer removable section, a coiled spring of a diameter to closely fit within the inner section, means engaging the spring" to hold the spring under tension, a wedge fitted s between the inner section of the door knob and the shank, and one end of the spring engaging the wedge to force the wedge between the shank and knob.
4. In a door knob'securing device, a door knob shank, a knob comprising an inner section and an outer removable section, said inner section having an opening to receive the shank of the door knob, a wedge positioned within the opening and engaging the shank to lock the knob to the shank, lugs within the inner section, and a spring mountedwithin the inner section and held between the lugs and wedge to urge the wedge longitn dinally of the shank.
In testimony that I claim the foregoing as my own, I have hereto afiixed' my signature. NATHANIEL B. STONE.
