UNITED STATES PATENT OFFICE.

CHARLES G. OVERMYER, OF HARTFORD CITY, INDIANA.

DRAWER KNOB.

Application filed June 2, 1921.      Serial No. 474,499.
To whom it may concern:
Be it known that I, CHARLES G. OVERMYER, a citizen of the United States, residing at Hartford City, in the county of Blackford and State of Indiana, have invented a new and useful Drawer Knob, of which the following is a specification.
This invention aims to provide novel means for attaching a knob and particularly a glass knob to the wall of a drawer or to any other object which is adapted to be provided with a knob. Another object of the invention is to provide novel means for illuminating the knob.
It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.
With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.
In the accompanying drawings:—
Figure 1 shows in section, a device constructed in accordance with the invention; Figure 2 is a rear elevation; Figure 3 is a section like Figure 1, but showing a modification.
The numeral 1 denotes the front wall of a drawer or any other object to which a knob may properly be applied, the wall having an opening 2. A knob is provided, the knob preferably being made of glass and including a body 3 provided with a reduced neck 4 defining a shoulder 5, the neck having a reduced stem 6, which is threaded. The shoulder 5 abuts against the forward surface of the wall 1. The neck 4 fits closely in the opening 2 to aid in holding the knob securely in place, and the stem 6 is received in the opening 2. A sleeve 7, which may be made of metal, is disposed in the opening 2 and is mounted on the threaded stem 6 of the knob, the sleeve being provided with an annular flange 8 at one end, the flange 8 bearing against the inner surface of the wall 1. The flange 8 is provided with projections adapted to engage the wall 1 and these projections may be made in various ways.
 
If desired, openings 9 may be punched in the flange, the resulting burrs 10 forming the projections above alluded to.
When the neck 4 and the stem 6 of the knob are inserted into the opening 2, and when the stem 6 is received in the sleeve 7, if rotation be imparted to the body 3 of the knob, the front wall 1 is bound between the shoulder 5 and the flange 8, the projections 10 biting into the wall 1 and preventing the sleeve 7 from rotating.
When a glass knob is mounted on a drawer and when the drawer is closed, the knob is given a darkened appearance, because the interior of the drawer is dark. One object of this invention is to provide novel means whereby such a darkening of the knob will be avoided. With this end in view, a bore 11 is formed in the stem 6 and the neck 4 of the knob, the bore being of successively decreasing diameters in order to form transverse surfaces 12. Reflecting material, such as mercury or white lead is placed in the bore 11 and cooperates with the surfaces 12 to increase the reflecting capacity thereof. The light passing through the body 3 will be reflected by the material 14 and, thus, the stem 4 and the neck 3 of the knob will be lighted up.
In the modification shown in Figure 3 of the drawings, parts hereinbefore described have been designated by numerals previously used with the suffix "a". The modification consists in omitting the bore 11 with its surfaces 12, and the reflecting material 14.
I claim:—
1. A knob of the class described provided with an inner end portion, and means for holding said end portion in an article, said end portion being provided with an internal reflecting surface.
2. A knob having a shoulder; and a sleeve whereinto a portion of the knob is threaded, the sleeve having a flange disposed in opposite relation to the shoulder, the flange having an eccentrically disposed projection extended toward the shoulder.
3. A knob of the class described provided in its inner end with a bore; and reflecting material in the bore.
4. A knob of the class described provided at its inner end with a bore of successively decreasing diameters defining a transverse reflecting surface; and reflecting material in
