Los Angeles, Calif.

Application December 10, 1931 Serial N0. 580,100

3 Claims. (or. 292-348) Our invention relates to a knob anchoring device and has for its principal object, the provision of relatively simple, practical and eflicient means for anchoring and fixedly securing the 5 knobs of doors, drawers and the like so thatsaid knobs are effectively held against rotary motion when positioned for use upon doors, drawers or swinging or sliding panels and the like.

With the foregoing and other objects in view, our invention consists in certain novel features of construction and arrangement of parts that will hereinafter be more fully described and claimed and illustrated in the accompanying drawing, in which:

Fig. 1 is a front elevational view of a metal ."plate that is adapted to be secured to a door or the.

like and which plate is provided with ribs that are adapted to engage in grooves in the door knob.

Fig. 2 is an end elevational view of a door knob and showing the grooves therein that receive the ribs on theplate. I

Fig. 3 is a sectional view taken lengthwise through a knob that is associated with a push catch and which knob is anchored by our improved means.

Fig. 4 is a horizontal section taken on 44 of Fig. 3.

Figs. 5 and 6 are respectively front and edge elevational views of a washer that is utilized for anchoring a knob to a wooden door or panel.

Fig. 7 is a sectional view taken through the center of a knob that is anchored to a door or panel by means of the washer illustrated in Figs. 5 and 6.

Fig. 8 is a perspective view of a knob having its inner end face grooved in order to be anchored in accordance with our invention.

Referring by numerals to the accompanying drawing and particularly. to the construction illustrated in Figs. 1 to 4 inclusive, 10 designates a metal plate having apertures 11 for the reception of screws or the like that secure said plate to a door, drawer or panel 12 and formed through the center of said plateis an aperture 13 that is threaded,

This threaded aperture receives the externally threaded end of a tube 14 that passes axially through a knob 15 which may be'formed of wood, metal, glass, porcelain, hard rubber or composition and formed on the outer end of said tube is an outwardly projecting flange 16 that overlies the adjacent portion of the knob.

Tube 14 provides a housing and guide for a spring held plunger 1'7, the inner end of which the line is connected to the actuating mechanism of the door or drawer latch. In order to anchor-the knobv 15 to plate 10 and effectively prevent rotation of said knob on the tube 14, one or more radially disposed ribs such as 18 are pressed outwardly from plate 10 adjacent to the aperture 13 and for the accommodation of these ribs, corresponding grooves 19 are formed in the inner end face of the knob 15 immediately adjacent to the axial bore 20 that is formed therethrough for the accommodation of the tube 14.

In assembling this form of knob anchoring device tube 14 is inserted through axial bore 20 in the knob and the inner end of said knob is now positioned against the face of plate 10 with the ribs 18 positioned within the grooves or recesses 19 and the threaded inner end of tube 14 is now screwed into the threaded aperture 13 in'plate 10 until flange 16 bears tightly against the outer end of the knob and as a result of the engagement of the ribs 18 in the grooves or recesses 19 the knob is very firmly held against rotary movement upon the tube 14.

The form of knob anchoring device illustrated in Figs. 5, 6 and '7 is designed especially for anchoring the inner ends of knobs to a door, drawer or panel without the use of the face plate 10 and i to the shape and size of the inner end face of the knob 15 and when the knob is applied to said wash- I er the grooves or recesses 19 in the inner end face of the knob receive the ribs 24, thereby forming an interengagement that prevents the knob from turning on the tubular member that passes axially therethrough and which tubular member secures the knob to a part of the push catch-or door latch. When the tubular member that passesaxially through the knob is screwed unto a projecting part of the door latch or push catch, the pressure of the knob against the lock washer 21 forces the prongs 22 thereof into the door drawer or panel and thus the lock washer with which the knob is interengaged is effectively held against rotation.

Thus it will be seenthat we have provided relatively simple, practical and inexpensive means for eifectively anchoring the knobs of doors, drawers,

panels and the like and which anchoring means is effective in holding the knobs against rotation when properly associated with the latch or push catch that retains the door in closed position.

It will be understood that minor changes in the size, form and construction of the various parts of our improved knob anchoring device may be made and substituted for those herein shown and described without departing from the spirit of our invention, the scope of which is set forth in the appended claims.

We claim as our invention:

1. In a knob anchoring means, the combination with a fixed member provided at its center with a threaded opening, of a knob detachably secured to said fixed member the contacting faces of which fixed member and knob are provided with interengaging portions and a tubular member passing axially through said knob and the inner end of which tubular member is threaded for engagement in the threaded aperture in said fixed member.

2. In a knob anchoring device, a plate provided on its outer face with a plurality of ribs and at its center with a threaded aperture, a knob pro vided on its inner end face with grooves for the reception of the ribs on said plate and means for clamping said knob to said plate which clamping means comprises a tube that passes axially through said knob and having its inner end threaded for engagement in the threaded aperture in said plate.

3. In a knob anchoring device, a plate provided with a centrally arranged threaded aperture, radially disposed ribs formed on the outer face of said plate adjacent to the aperture therein, a knob provided on its inner end face with radially disposed grooves for the reception of the ribs on said plate and means extending axially through the knob for securing the same to said plate which securing means comprises a tube that passes axially through said knob and having its inner end threaded f or engagement in the threaded aperture in said plate.
