NUT-LOCK.

Specification 01 Letters ratent. Patented Ailg. 15, 1911 Application filed October 21, 1910; Serial No. 588,293,

To all whom it may concern:

Be it known thatI, IRVING (J. WVooDwARn, a citizen of the United States of America, and a resident of Chicago, county'of Cook, State of Illinois, have invented certain new and useful Improvements in Nut-Locks, of which the following is a specification,

The main objects of this invention are to provide a simple, efficient, and'inexpensive form of nut lock:

An illustrative embodiment of this invention is shown in the accompanying drawings, in which-e,

' Figure 1 shows a nut and bolt locked by a nut lock constructed according to'this in-' vcntion. F ig. 2-is a section of the same taken on the lineAe-A ofFig. 1. Fig. 3 is a'plan view of the blank before being bent. Fig. 4 is a front elevation of the finished nut lockv showing the eccentricity of the apertures. Fig. 5 is a section of the same taken on the line B-B of Fig. 4. I

'In the form shown in the drawings the nut lock comprises a fiat pie'ceof resilient metal 1 b'ent upon itself to substantially U shape so as to form' a pair of

legs

2 and 3 extending in the same genera-l direction and connected together by an inclined back or yoke 4. Apertures 5 and-6 are punched in the blank so that, when the piece of metal is bent to theshape shown in the drawings, they will be eccentricallyf located with respect to each otherand their centers lie in a line i lined tothe-zlegs in the samegeneral direction as the inclination of the back. These apertures are unthreaded and are preferably oblong or elliptical, the major mean between the..outside and root diameters being greater than the outside (1i ameter-of the bolt." I

The size of the apertures relative location allows the edgeof each aperture to be seated in the thread grooves 7 for a short distance only as at8 and 9 re spectively. On account of the eccentricity of the apertures thelegs ofthelock enga e respectively opposite sides .of' the bot.

.When in position on the bolt the adjacent leg 2 ofthe lock comes up .fiush against-"the" face of the nut 10 and the back 4; is inclined-- away from the bolt and from the face off: the nut.

fingers up to the nut 10 and then it may-be set up with a wrench thereby wedg ng the edge of the aperture at 5 between the thread 5 and 6 and their The nut lock may be screwed on with the and the face of the nut 10. For all ordin ary uses the setting up 'of the nut lock with the wrench will, on account'of the incidental' springing together of the-legs of the lock, secure themitlO against removal until the nut lock has first been removed. However, it' may in some instances as with small bolts where the resiliency of the nut lock is reduced to a minimum due to its'size, be desirable to cause a more secure seating of the

parts

8 and 9 in the thread grooves 7. This can be accomplished by striking a blow with a hammer at- 8 which, on account of the inclination of the back, will tend to increase the eccentricity of the apertures and thereby increase the grip of the nut lock on the bolt.

Although but one specificembodiment of th s invention has been herein shown, it will be understood that numerous details of the construction shown may be alteredor omit this invention.

I claim l. A nut lock, com rising a piece of metal bent upon itself to orni a pair of legs ex tending in the same, general direction and having eccentrically' locatedapertures therein. i i

2, A nut lock, comprising a fiat piece of metal bent upon itself to form a'pa'ir of legs ted without departing from the spirit of extending in the same general direction,

each of said legs having an aperture therein, said apertures being eccentrically located relatively to each other.

A nut lock, comprising a flat piece of metal bentgupon itself to form a pair of legs extending: in the same general direction,

each of said legshaving an aperture therein,

said apertures being oblong and eccentrically located relativelyrof each other.

i. A nut lock com rising a flatv piece ,of metal bent upon itsel to'form a pair of legs extending in the same general directi0n,

each ofsaid le gs having. an aperture therein, rsaid apertures being oblong and eccentrically located relatively of each other in the direction 0 ,their shorter diametfi is.

5. A nut. lock, comprising affiatpiece of metal, having therein a pair'of apertures 'spaced apart and being bent upon itself be tween said apertures toform a pair of 'legs extending in the same general direction and connected by a back inclined atan angle to .said generaldirection, the inclination of Sflld bfiCk being such as to make the "aper- .tures in said legs eccentric to each other."

6. A nut lock, comprising a piece of metal having therein a pair of apertures spaced apart and being bent upon itself to form a pair of'le'gs extending in the same eneral direction and having eccentrically ocated apertures therein, and a back inclined at an acute angle to one of said legs.

7. A nut lock,'compris1ng a piece of metal bent upon itself to form a pair of legs extending in the same general direction and having eccentrically located apertures therein, and a back connecting said legs and inclined thereto in the general direction of the slime of centers of said eccentric apertures. l

8. The combination with a bolt and nut, of a nut lock comprising a flat piece of metal bent upon itself to form a air of legs extending in the same general 'directiom eachof said legs having an aperture therein, the

edge of one of said apertures. being adapted to engage the threads of the bolt at a point circumferentially spaced away from the point of engagement of the edge of said point of engagement of the edge of said other a erture with said threads.

10. e combination with a bolt and nut, of a nut lock com rising a; flat piece of metal bent upon itself to-form a pair oflegs extending in the same general direction,

each of said legs having an unthreaded aperture therein, theedge of one of said aperturesbeing ada'ptedto engage the threads of the bolt at a point circumferentially spaced away from the point of engagement of the edge of said other aperture with said threads.

1 11;. The combination with a bolt and nut, of a "nut lock' comprising a fiatpiece of metal bent upon itself to form a pair of legs extending in: the same general direction,

each of said legs having an aperture therein, said apertures being of a diameter not less than the mean between the outside and root diameters, of the bolt, the edges of said apertures being adaptedto be seated in the thread grooves at points spaced apart circumferentially, 5 i

12. The combination with a nut and bolt of a nut look comprising a flat piece of metal bent upon itself to form a pair of legs extending in the same general direction, each of said legs having an oblong aperture therein, the major, diameter of said aperture being not less than the outside diameter of said bolt, and the minor diameter being not less than the mean between the outside and root diameters of said bolt, the edges of said apertures being adapted to becomeiseated .in the thread grooves at points substan: tially diametrically opposite.

It is hereby'oertified that in Letters Patent No. 1,000,657, granted August 15, 1911,upon the application of Irving 0. Woodward, of Chicago, Illinois, for a nimprovement in Nut-Locks. an error appears in the printed specification requiring correction as follows: Page 1, lines 36-40 the sentence These apertures ,are' unthreaded and are preferably oblong or elliptical, the major mean between the outside and root diameters being greater than the outside diameter of the bolt. should read bese apertures are unt/treaded and are preferably oblong orellz'ptical, the major diameter being greater than the outside diameter of the bolt, and the minor t diameter not less than the mean between the outside and root diameters of the bolt and that the said Letters Patent vshould be read with this correction therein that the same may conform to the record of the case in the Patent Oflice.
