H. .J. KASCH INTERCHANGEABLE KNOB FOR DIALS Filed March 24, 1924 FIG. 6

INVENTOR/ 44; ATTORNEY Patented Feb. 17, 1925.

I v UNITED STATES PATENT OFFICE.

HENRY J. KASCH, or DAYTON, OHIO, AssIeNon 'ro THE KURZ-KASCH COMPANY, or DAYTON, OHIO, A oonronerron or 01110.

INTERCHANGEABLE KNOB FOR DIALS.

Application filed March 24, 1924. Serial No. 701,384.

To all whom it may concern:

Be it known that I, HENRY J. KASCH, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Interchangeable Knobs for Dials, of which the following is a specification. i This invention relates to new and useful improvements inknobs for dials, and has particular reference to interchangeable knobs for radio dials.

It is the principal object of my invention to provide lmobs of different styles and sizes 1 with means which will adapt any one of them to fit adial of thesame or a different color, so that a knob of the style, size and color desired may beeasily attached to the dial.

It is another object of my invention to -make knobs of the above character out of a molded composition such as bakelite, shel-- lac or a cold molded product. In the accompanying drawings, Figure 1 ii is a front view of a dial to which a small knob of one style is applied. Figure 2 is a side elevational view of the same. Figure 3 is a cross sectional view thereof taken on the line 3-3 of Figure 1.. Figure 4, is a side elevational view of the same dial having atta'ched thereto a larger. knob than that shown in the preceding figures.- Figure 5 is a front view of the same dial tb which a knob of a different style is secured. And Figure 6 is a side elevational view of the same.

Throughout the specification and drawings, similar reference character denote corresponding parts. Referring to the accompanying drawings v illlustrating my invention, the numeral 1 designates a dial for radio tuning that is made of a molded composition such as bake-- suflicient distance to receive the bushing 3,

which contains therein a bore of the diameter required to fit over a variometer, vario coupler or other shaft 6.. (See Figure 3.)

The bushing 3 and hub portion 4 of the knob 5 have alined radial holes to receive a screw 7 which is adapted to be screwed into said holes through a hole 8 in the outer wall of the knob that is in alinement with them. This screw is adapted to be screwed through the holes in the bushing 3 and hub portion 4 of the knob into engagement with the shaft 6, so that when the knob is turned, it will not only rotate the dial 1, but the said shaft which may be that of a variometer, vario coupler or other device.

Any number of knobs of difierent styles and sizes may be provided with the means I have just dmcribed, so that any desired one of them may be inserted in a dial. For example, one person may wish to use the small =knob 5, in which event it may be inserted in the dial 1 as shown in Figures 1, 2 and 3. On the other hand, if his the desire of a person to employ a large knob 9, it may just as easily be secured to the same dial; or a knob 10 of the style shown in Figures 5 and 6 may be attached to the dial if desired. It is thus possible to make up any number of knobs of diflerent styles and sizes from which one may be-selected for ready attachment to a dial that is used for radio or other purposes.

Having described my invention, I claim:

1. The combination with a 'dial made of a molded composition and having a central threaded shaft-hole, of a knob constructed of a molded composition and having a hollow interior, a hub projecting axially from the inner surface ofthe outer end of said knob, and a bushing molded in said hub and being exteriorly threaded on its outer end for entrance into the threaded shaft-hole in said dial.

2. The combination with a dial made of a molded composition and having a central threaded shaft-hole, of a knobconstructed of a molded composition and having a hollow interior, a hub projecting axially from the inner surface of the outer end of said knob, a bushing molded in said hub and being exteriorly threaded on its outer end for entrance into the threaded shaft-hole in said dial, the outer wall of said knob and ing, for engagement with said shaft, for

the hub therein having alinedradial holes the purpose specified.

adapted to be brought intoalinement with In testimony whereof I have hereunto set 0 a radial screw hole in saidbushing, a shaft my hand this 22d day of March, 1924.

5 over which the latter is fitted, and a screw adapted to be forced through the alined -holes in the knob and the hole in the bush- Witness HOWARD S. SMITH.
