Description

Aug. 6, 1940. o. P. cRlM KNOB ATTAQH'ING'DEVICE Filed March 14, 1939 ,2f IIHIIVIIIIIT-HHII INVENTOR ATTORNEYS Patented Aug. 6, 1940 UNITED STATES PATENT OFFICE KNOB ATTACHING DEVICE Otis P; Crim, Anderson, Ind. Application March 14, 1939, Serial No. 261,815

1 Claim.

This invention relates to door knobs and has for an object to provide means for releasably .holding` a door knob to its shank without the use of the conventional screw which is prone to work loose and become lost.

A further object is to provide a device of this character which will be formed of a few strong simple and durable parts, which will be inexpensive to manufacture and which will not easily get out of order. f

lWith the yabove and other objects in View the invention consists of certain novel details of construction and combinations of parts hereinafter lully described and claimed, it being understood that the various modifications may be resorted to within the scope of the appended claim without departing `from the spirit or sacriiicing anyl of the advantages of the invention.

In the accompanying drawing forming part of I this speciiication,

Figure 1 is an end elevation of a door equipped with door knobs constructed in accordance with the invention, parts being shown in section.

Figure .2 is a plan view of the shank and a v door knob secured to the shank through the medium of a spring pressed pawl.

Figure 3 is a cross sectional View'taken on the line 3 3 of'Figure 1. j Referring now to the drawingin which like in the various views, I0 designates a door and II a conventional bolt and lock mechanism applied thereto. In carrying out the invention' each door knob I2 is provided with a radial passage I3 which is open at its outer end and at the inner side. Lugs I4 are formed integral with the inner side of the knob and with the stem I5 of the knob and are located at opposite sides of the inner open side of the radial passage I3. The stem I5 is provided with an 'opening I6 nearits inner lend and in that side thereof with which the lugs I4 are formed. A groove I1 is formed in the last named side'of the stem and extends from the opening BS to the lower end of the radial passage i3;

A substantially Z-shaped pawl I8`is located between the lugs I and is pivoted at one of its e1- bows between the lugs through the medium of a pivot pin i9 passed through the lugs and headed up exteriorly of the lugs as shown in Figure 3. One arm of the pawl extends into the outer end of the radial passage and is attened as shown at 29. A coil spring 2| is seated in the passage and bears against the flattened end of 55 the pawl. 'I'he other arm of the pawl is mounted in the groove I1 of the door knob Stem and" has characters of reference designate similar parts.

formed integrally therewith a tooth 22 which is disposed'in the opening I6 of the stem.

A spindle 23 of substantially rectangular cross section is mounted in the door lock mechanism I2 in the usual manner and is provided with longitudinal series of rack teeth 24. The tooth 22 of the pawl is adapted to engage one of the teeth on the respective end of the spindle and secure the knob to the spindle. The spring 2| releasably holds the pawl in engagement with the spindie without the use of screws or other connectors.

To apply the knob it is simply necessary to slide the knob inwardly toward the door, the tooth 22 of the pawl engaging the rack teeth and lodging in rear of one of the teeth as the knob arrives in nal. position against the conventional washer 25 which is sleeved on the spindle at the face plate 25 of the lo'l mechanism II. To remove the knob it is simply necessary to insert a tool such as a pencil, or small screw driver into the passage I3 and press down upon the flattened end 29 of the pawl to compress the spring and swing the pawl on its pivot I9 to disengage the tooth 22 from the rack teeth of the spindle.

From the above description, it is thought that the construction and operation ofthe invention will be fully understood without further explanation.

What is'claimed is: 1

A door knob provided with a spindle receiving stem, a spindle in said stem having rack teeth,

the door knob being provided with a radially extending passage having an opening through the outer periphery of the knob and an opening through the door confronting face of the knob, parallel lugs formed integrally with the door confronting face of the knob on opposite sides of said opening therein, said stem being provided near the end with a radially disposed opening, there being a longitudinal groove in the stem extending from said radially disposed opening in the CII stem to the lower end of said radiallydisposed l passage in the knob, a substantially Z-shapedV pawl pivoted at its outer elbow between the lugs, one arm of the pawl extending through said opening in the door confronting faceoi' the knob and projecting into said radially disposed passage in theknob, a helical spring in said radially disposed passage bearing against said arm of the pawl, the other arm of the pawl being mounted' insaid groove of the stem, and a tooth formed integral with the last-named arm disposed in said radial opening of the stem and held in engagement with said rack teeth of the spindle by said spring.
