Specification of Letters Patent. Application filed January 22, 1908. Serial No. 442,066.

Patented July e1, 1908.

To: all whom it may concern:

Be it'known that I, CHARLES S. NORRIS, a citizen of the United States, residing at Troy,

,111 the county of Miami andState of Ohio,

have invented certain new and useful'Im provements in Nut-Locks, of which the'i'olwing is a specification.- 'M invention relates to improvements in nutcoke, and the object of my invention is to provide a nut lock which will be simple in construction and eilective in operation.

My invention consists in the constructions and combinations of parts hereinafter de'-' scribed and set forth'in thelclaims.

In the acc'ompanyin drawings Figure 1 is a sectionalviewof a evicev embodyin invention; Fig. 2 is a'section on the hue x e of Fig. 4,- Fig. 3 is a detail ofthe locking'screw head or cap; Fig. 4 is a plan view of thedevice; Flg. 5 is a detail 0 the connecting pin between the lock and the nut.

Like parts are represented by similar characters of reference in the several views.

In the exam le of this invention which I have shown in t e drawings I have illustrated it as applied to an ordinary bolt, although it will be obvious that it can be applied to an axleor any lock the nut. In the said drawings, are resentea bolt and b itsrnut which is screwe on to the end of the bolt by ri ht hand threads in the ordinary manner. 1 The end of the bolt is provided with a screw threaded socket, a

the threads of which are left handed and into this socket is screwed the stud, c of a lock mg head or cap, a. y The locking head, 2, is provided with a longitudinal perforation, c

' and the nut, b, is provided with a seriesroi longitudinal perforations, b b, adaptedfto register with the. perforation, "a In -the drawings 1. have shownthe nut, I), provided with four 0 enings or perforationsbut a eater num er of these may be employed if esired;

.When-the nut, b, has .been screwed to its proper position on the bolt or other device to which it is to he applied, the studded cap or head, a, will, be screwed into the socket, a as far as possible until its opening, a registers with one of the o enings, 6 of the ,nut and e inserted throug there'- then a pin, d, will other device where it is desired to y ective openings. This pin, (1, is in the nature of a cotter in, the respective halves being offset. sli ht y as at (2 these oflsetportions being p aced at a point in the pin so as to lie between the head and nut when the pin is iii position and thus act in the nature of a spring -stop to hold the pin in its position; the

he pin permltting the insertion of 5 offset portion throughthe openings in 69. the'head, c, in a manner which will be well understood. After the pin is in position, its ends, 1 may be bent over so as to further 'clench the pin inits position. In order'to provide for'the clenching or unclenching of the ends of the pin'I preferably'provide the .nut, b, about itsscrew-threaded opening with a boss or shoulder b so that when the nut is screwed up againstthe partto which the bolt is applied a' space will be left between said part and the main body of the nutjtsii afiord access to the ends of the in.

By the construction escribed it will be seen that an effective lock is provided for the nut whichmay. be easily and quickly removed and. replaced at any time without destroying either ;-the nut, lock or pin. Also by this construction a Wide range is provided forthe adjustment of the nut with reference to its lock for the reason that by simply providing different sized .ins the nut may be separated from the ocking head, any. distance within the range of the length of the pin. b

I have shown the oil-set at, d Fig. 4,. 35 and have described same as being formed before the pin is inserted in osition,'but it is obvious that an oil-set mig t be formed in various ways and I do not intend to be limited to the formation of thisofi-set porfiesitlon. p

Having thus described my invention, I claim i Ina nut-lock, a screw-threaded part hav '95 ing a nut threaded thereon, a screw-threaded if socket in the end of said part, the threads of which are opposite to the outside threads of said part, a studded head or cap adapted to Y be screwed in'tp said socket, a perforation in said head or. cap, a series of perforations in said nut. adapted to register with the perfo tron prior to the time the pin is inserted in ration of the head 01' cap, a cotter-pin adapt- In testimony whereof, I have hereunto ed to be inserted in the perforation in said set my hand this 17th day of January, 1908. head or cap and through one of the perio- CHARLES S- NORRIS rations of said nut, said cotter pin being offset at a point therein which lies between said head and said nut, substantially as and for the purpose specified.
