DooRxNoB FASTENER.

Application nled August 2, 1923. Serial No. 655,219.

This invention relates to' a door knob fastener and especially to means for locking a door knob against endwise and turning movement with relation to the spindle upon which it is mounted. v

The object of the present invention is to generally improve and simplify the construction and operation'of fasteners of the character described; to provide a knobl fastener which is carried by the spindle and which is automatically projected into locking engagement with relation to the knob -when this is applied; a knob fastener which secures the knob both against endwise and turning movement with relation to the spindle, and furthermore a fastener which cannot .work loose or become lost, and which may be manually released when it isnecessary to remove the knob, for instance, when repairing the lock, or otherwise. Other objects will hereinafter appear. 1

One form which my invention may assume is exemplified in the following description and illustrated in the accompanying drawings, in which- Fig. 1 is a central, longitudinal section of a door knob, and the spindle upon which it is mounted, said figure also illustrating the fastening mechanism employed.

Fig. 2 1s a cross section on line 2 2, Fig. 1.

Fig. 3 is a cross 'section on line 3 3, Fig. 1.

Fig. 4 is a. plan view of a portion of the spindle showing the depressed portion in which the .fastener actuating spring is mounted.

Referring to thedrawings in detail, and particularly to Fig. 1,'A indicates an ordinary door knob, 2 the sleeve or shank of the same, and 3 the spindle upon which the knob is mounted. A tubular spindle is in this instance illustrated and the object of the in-.

vention is to secure the knob on the spindle both against endwise and turning movement with relation thereto. Furthermore, to provide a fastener whichlis automatically projected into lookin engagement when the knob is applied an which may be` manually depressed torelease the knob if it is necessary to remove the same. vThis is accomplished in the following manner:

The spindle, which in this instance is tubular, is first slotted transversely as indicated at 4. A round hole is then drilled or punched a distance therefrom as shown at 5, and the intermediate'portion 6 is then depressed by means of a die o r the like to form i' a segmental or half round channel 7 which tapers from end to end; the widest portion being presented towards the punched portion 5.

The fastener proper indicated at 82 and which is perhaps best illustrated in Flgs. 1 and 3, consists of a flat rectangular-sha ed plate, the lower portion ofwhich is rovi ed with two lugs 9 between which is ormed a V-shaped recess 10. The plate is` slidably mounted in the slot 4 and is guided by the enlarged end of -the' depressed portion 6 on one side and by the rounded wall of ,the

spindle shown at 11 on the opposite side. 70

The plate is vertically movable 1n the slot 4 and it is normally held in raised or projected position by means of a spring 12. This spring may be fiat or as here illustrated is preferably constructed of round spring wire.

One end of the spring is inserted throughf the punched portion 5 as indicated at 13,

and it is then bent over the upper portion of the depressed member 6 as indicated at 14';

lthis 'portion forming a support or fulcrum 80 for the spring which tends to force the opposite end 15 in an upward direction. This end passes under the late 8 and is centered with relation vthereto1by the lugs 9 and the V-shaped recess 10, the wire being suiiiciently long to project beyond the plate and in under the rounded shoulder of the spindle shown at 16.y A

The spring serves three functions, first,

that of normall projecting the plate; secondly, that of orming a stop which limits upward movement of the plate by engaglng the shoulder 16, and, third, that of forming a stol which limits 4downward movement of the p ate by engaging the lower portion of v the member 6. j

The shank 2 of the knob is slotted as indicatediat 17 to receive the upper end of the plate, the locking plate when projecting through the slot serving the function o locking the knob and shank against endwise novement on the spindle. It also serves the function of locking the knob and shank against turning movement, but the plate is not entirely depended upon for thls urfose as a key is formed in the opposite en o the shank as indicated at 18 w ich projects into a longitudinal key-way 19 formed inthe spindle. The key and the key-way thus secure the knob and shank against turnin movement, while the plate 8 secures the kno and shank against endwise movement.

' .dinal axis of the spindle, aradially slot formed thereln adapted to register with l the locking plate radially outward through comprising a tubular spindle having The fastener here illustrated is exceedingly sim le in construction and will not be accidenta y displaced or released by turning movement of the knob, vibration or otherwise, as the plate is always heldin projected position by the tension of the'spring 12 imposed thereon. For instanc'e, most door knobs are secured to the' spindles by means of ordinary set screws. These screws work loose vand drop out, thusl leaving th'e knob free to be removed. This objection is entirelyl overcome by the*prese1t structure. The fastenerfmay furthermore' 1'be manually depressed and it is therefore possible to removeA the knob if the lock is to be repaired, inspected or otherwise.

While certain features of the present in` vention are 'more or less specifically illustrated, I wish it -understood thatavarious4v changes in form and proportion may be resorted tofwithin the scope of the appended claims; similarly, that the materials and finish ofthe several parts employed may be such as the experience and `judgment of .the manufacturer may dictate or various uses may demand. l l.

vHaving thus described my invention, what I claim and desire toA secure by Letters Pat- 1. A device of: the character described, a slot ongitumovable locking plate' carried by. the spindle 4 and guide in the' slot, a knob ada ted to be received by the spindle, said kno having a formed therein transversely .of the the slot in the-spindle, and a spring disposed longitudina ly of the tubular spindle and interiorly thereof and adapted to force 4 the y sprin the spindle and into the Slot 'inI the knob te secure the knob.

2. A device of the-character described,

comprising a tubular spindle having a slot formed therein disposedtransversely ofv the longitudinal axis ofthe spindle, a radially i movable locking plate interior of the spindle and ggided in the slot, a knob, a shank on thev therein adapted toregister with the slot in the spindle, a spring .interiorly tubular of the spindle engagin the locking plate and exertlng a, pressure o project the locking plate into the Slottedshank to lock the kno against removal from the spindle, and means tion of the spindle, a spr-ing extending longi-A tudinally through the channel, one end of passlng through the perforated end and e-other end of the spring exerting an outward pressure on the locking 'late to normally .project the same, -a nob adapted to be recelved by the spindle, and a shank forming apart of the knob, said shank having a slot formed therein into ob adapted to be received -by they spindle, said shank having a slot formed` `interiorly of the tubular spindle to secure v which the locking plate projects when'the i knob is in positionon they spindle, said plate when projected intothe slot securing the knob against movement on the spindle.
