KE Ylnrne AND 'rrrELrK-n 1 Application filed hiovember 18,1921. seriaino. 515,239;

State of Minnesota, have invented certain new and useful Improvements in and Relating to Key Rings and the like,.of which the following is a specification.

This lnventlon relates to certain 1mprovements in and relatlng to key rings; and the objects and nature of the invention will be readily u'nderstoodby those skilled in the art, in the light of the accompanying drawings and specificationsf-illustrating what I now believe to be the preferred embodiments or mechanical expressions of my invention from among other forms, constructions and arrangements within the spirit and scope thereof.

Theobjeet ofthis invention is to rovide certain improvements in key rings andthe like, with the end in view of increasing the e'fficiency'and ease with which keys may be attached and detached. v I

A further object of this invention is to provide such improvements and changes in the design and construction of key rings that will in the manufacture of the same obviate all operations of swaging, forging, or of in any manner changing the form of the cross section of the stock from which they are made.

A further object of this invention is to" provide such improvements and changes in the design. and construction of *key rings as will allow of the use of such standard material in its manufacture as to obviate Jall tempering and finishing forming operation.

A further object of this inventionfislto provide certain improveanents in, the con SillUOtlOllOf key';r1ngs whereby the customs ary thumb-nail method of attaching and de same and the fre quentinjuries ar slng from, said method may taching keys from tie be eliminated.

With these and other objects in view, my,

invention consists in certain novel features in construction andin combination and a1:-

rangements as. more fully and particularly tion, 1 and nto thereceivlng space, 1, as

set forth and specified hereafter.

Referring to the accompanying drawings: Fig. 1 is aside view showing the ring with a key attached.

Fig. 2 is an edge view showing'thering with key attached.

processes after the] r 7 p 2 of the kev,.2, as'shown ln Fig. 4. The

drawings is manufactured from a single piece of commercial 1 sp1'ing tempered" and polished round wire forming approximately two complete circles orturns and is at a point intermediate its ends offseta distance equal to the diameter'of theiwire from which the ring is made, forming an oblique portion, 1 1

The extremeend of the wire on thereceiving side of the ringis formed with a laterally projectingarch, 1 forming the receiv- I '75 mg space, 1, and also with an inward curve of a sufiiciently reduced radius to admlt of the extreme end, 1 .of the arched portion passing nwardly of theobhque POIt1011,. 1 -when,the curved portion, 1", is compressed by passing keys having .exceptionally'small openings in their. heads, around thering,

' "Figures 3, 4 5 and 6 are views showing the I I l i ring with the key infthe different stagesof which is necessary when securingadditional keys tea ring with a key of the above description attached thereto.

The opposite end of thewireulies parallel and concentric with the main body of the ring and its extreme end, 1 abuts with the oblique .portion,1

To secure the key: 2 to the ring 1, the edge of the ringed end, or head, 2 of the key is .placed in the key receiving space, 1, of the r ng, asshown in Fig, 3, and is then pressed arched'portion, 1 passes through the eye,

direction of -the key; is then reversed as shown in Fig. 5, and 1s moved completely ar'oundthe ring, as shown in 6, until it passesout from under the discharging end of the ring 1, and assumes the position shown in Figures 1 and 2, key secured to theringl which show the downwarduntilzthe extreme end, 1, of the To removepthefkey, the coils-of the key ring" are expanded'sufiiciently'to allow the ringedportion, 2 of the key, 2, to pass under the extreme-end, 1 of the arched por shown in Figures 7 and 8 It is then moved completely around the ring into the 'posi ingend, 1".

It is evident that various changes, inodifications and variations might be resorted to wlthout departing from the splrit and scope of my invention, therefore, 1 do not Wish to limit myself to the exact disclosure thereof;

What I claim is said Wire, a laterally projecting arched per tion at one end of sa d Wlre having ts terminus lnside of said coil and hav ng an1n- Ward curvature of a suficiently reduced radiusto admit of its extreme end passing inwardly of the oblique portion when compressed.

2. In a key ring, a coil of approximately two complete turns, produced from a single piece of Wire of a uniform cross section throughout its entire length and having a laterally projecting arched portion at one end of said Wire having its terminus inside of said coil and having an inward curvature of a sufiiciently reduced radius to admit of its extreme end passing iiut 'ardly of said coil.
