each having a solid base integral with the knobitseli. p p I ,1 p To these and other ends, our invention particularly pointed out inthe claims. 7
Referring to thedrawings :in which. like.

Figure 5 is a fragmentary View of the lower end of one form of tool for producing projections upon the knob;
Figure 6 is a View of the contact face of the completed knob; and
Figure 7 is a modified form of tool.
The type of knob such as is shown in the drawing and described herein to illustrate our invention is such as is generally used for Specification of Letters Patent;

though, of course, it is not limited thereto.
thereontliat-theyi haue nosolid zbaser Our invention is largely designed to produce a solid turned knob with projections 01' 9s nifo m in s a e t ize or. no s si s red, .andeach having; a sol d base and ,ta-'

16 which are below the contact-face A centralrecess 17 isia lso provided'in the base i ei dell drill fe -th ope in 8 t e which isfsubs'equ'ently threaded as shown in r w is no form of tool (byiwhichthe base .of -the knob can be formed substantially asabove -desoribed ,is shown in Figure 3 and designated by the numeral; 19 the,,diameter, of
which. may beyaried as, desired. 7 ;After the. kn b l e fo med and ha ed fro th b r it i held weenl-e ,p zmf i si an df2l with the ring 13 1 projecting beyond t rf r lhereefa 'Aitoe 2,: e nae e rality of recesses 23 therein corresponding in shape with the finished projections or prongs 24 and substantially in cross-section the same size and shape as the cross-section of the ring 13 is now brought up against the knob and such portions of the ringl3 as lie between the-recess 23 in the tool 22 are compressed or flattened out. The remaining portions of said ring form the projections or prongs 24 which as shown are of substantially uniform size and sh p have a solid Patented, Fem-2e; 1922,.
/ What has been heretofore impossible topr'cywde/Witha solid turned knob isaneans I upon the contact facelthereof gto preuentyits rotation, without attaohingauiz ili ary parts thereto or so forming projecting gparts e1 by. turni g a portions 1 t er wi h, t ese betrance thereof into the surface rwithj which base and are pointed toward the top. By
varying the shape of the sides of the ring 13 or the recesses 23 in the tool 22, or both,
"the shape of the prongs can also be changed from those herein shown. Eight projections or prongs 24 are shown in the drawings, but
. it is obvious that a quarter or less number can be formed equally aswell. 1
The face of the tool v22, may if desired, be' 'pr'ov'idedwith a ring 25, having the recesses 23 therein, the diameter thereof being such as to permit its enteringthe recesses 15 and16 without any portion of the total engaging the contact face 12.
If the metal in'the ring 13 has a tendency to flow outwardly by the action ofthe tool 22 thereon the recesses 15 and 16 accommodate this movement so that upon completion of the knob the contact surface 12 is straight and all displaced metal is below the face thereof.' I j While wehave shown in the drawin a knob out from a solid bar, our metho is equally applicable to a cast; knob, a ring 13 being turned or tuned up upon the contact face thereof.
" 1 Minor changes and alterations maybe made w thin our invention'aside from those herein suggested and we would therefore have it understood thatwe do not limit our selves to the exact construction herein'show'n and described, but claim all thatfalls fairly within the spirit and scope of our invention} l the contact face thereof, and thencompress' -W hat we claim is our invention, and desire to secure by Letters Patent, is:
