This invention relates to a threadless nut or collar, and has for its primary object and purpose to provide means carried by the nut of collar whereby the same may be very easily, quickly and securely attached to a shaft or bolt, andl also removed therefrom when necessary by the, operation of a single retaining element which can be readily effe'ctedv without necessitating the usefof a tool or implement of any kind.

More particularly, my invention has for its essential object and purpose to provide a.

simple and novel form of spring locking member carried by the nut for cooperation with the walls of ar groove in the bolt or shaft, and whichmember is so constructed that it can be easily actuated by the fingersy of the hand and disengaged from said groove kto permit of the axial movement of the nut to or from its applied position.

lVith the above and other objects in view, the invention consists in the improved threadless nut or collar, and in the form,

construction and relative arrangement of the several parts thereof `as will be hereinaft-er more fullyk described, illustrated in the accompanying drawing, and subsequentlyincorporated in the subjoined claims.

In the drawing, wherein I have illustrated one simple andpractical embodiment of the invention, and in whichA similar reference characters designate corresponding `parts throughout the several views,-

VFigure l is an end elevation partly in section showing the retaining member in full lines in its locking position and in dotted lines in the released position, thev section being indicated by the line 1-1 in Fig. 2, and

Figure 2 is abottom plan view of the de.

vice as seen in Fig. l, a part of the nut being shown in section.

Referring in detail to the drawing, 5 indicates a shaft or rod having an annular groove 6 in one end thereof.

The nut or collar 7 is formed with an external annular groove 8 and in line with this groove, the nut 7 at one lside thereof is provided with a slot 9 opening through the inner face of the nut.

` `Theretaining member consists of a length of resilient wire having one end portion thereof bentor curved as at `il() and seated in the groove 8 at a point which is substan` tially diametrically opposite toA the Vslot 9. Frein 'this curved end portion," thewire is extended outwardly from the base of the groove. 8 at aslight inclination as indicated atlll, and is then `laterally extended and formed with the bend l2. From this bend G0 a long straight. section 13 of the wire extends through the slot `9 and'normally lies in intersecting'. relation to the inner longitudinal face of the nut. The other extremity of the wirey projects laterallyv beyond the side of 65 thef'nut and isA bent to fform' theA terminal looplt."` fA In the `operation and useiof the device'as abovefdescribed, in applying the. nut to the endofr the shaft or bolt, the thumb is placed vupon vthe surface o f vthe nut between the bend y'12 andthe; terminal loop 14 of the retaining member with r'which the` irs't two fingers of 'the'haiid are respectively engaged and sulfi-r cientfpr'essure is exerted against the terminal loop lll to position the straight portion 13 of the retaining member outwardly beyond the inner faceof the nut 7. The nut may then be passed over the end of the shaft, and upon the release ,of pressurev against l the terminal ,loop 14e' of the vwirelretaining member, the part 18 thereof willi snap into the groove' 6 inthe surface of the shaft, thereby securely locking .the nut or collar against an` axial movement relativeto the shaft though permittingV of its turning movement thereon. Y

"Vhenit is desired to remove the nut or collar, this may be readily accomplished by V simply applying the finger andV thumb of the ,n hand'as above explained and forcing the end loop/,14 ofi the wire retaining member outwardly to substantially the dotted line 11 of Fig. l of the drawings so thatthe ynut can then be'withdrawn longitudinally from the end of the shaft. i It is thusseen that by the use` ofa retaining member of this form, the nut can be very easily and quickly applied or lremoved'without the use of a tool of any kind, and also byeliminatingth'e usual threads, the possibility ofthe nutv becoming immovably locked to the shaft by reason of Inutili-5% tion of the threads will be obviated, also the necessity of rethreading is avoided by means of the present invention.

From the foregoing description, considered l n n l 1n connection with the accompanying drawing, the construction and several advantages of the device will be readily understood.

*havey found the particular form and construction of the retaining member as herein shown and described to bevery advantageous in practical use, but it will nevertheless be understood that this retaining member both as to the construction thereof and the manner of its assemblage with the nut might be embodied in various other alternative forms. It is therefore, to be understood that I reserve the privilege ofV resorting to all such legitimate changes in the various details of the device as may be fairly considered within the spirit and scope of the invention as l claimed.

I claim: l. Invcombination with a shaft having a taining member adapted to normally seat in the groove in the shaft to thereby lock the collar against axial movement while permitting of its rotation relative to the shaft.

3. A collar having a transverse slot in one side extending entirely through the wall thereof, and a retaining member for said collar consisting of a length of resilient wire permanently attached at one of its ends to the collar and having a part at all times positioned within said transverse slot and extending therethrough for engagement with a circumferential groove in a shaft to retain the collar thereon and said wire at the opposite ends of said part thereof and externally i of said slot being formed into finger engaging loops whereby said part of the wire may be sprung from its normal position out of the shaft groove to permit of the removal of the c-ollar.

In testimony that I claim the foregoing as my invention, I have signed my name hereto.
