Application filed September 14, 1912-. Serial No. 720,406.

To all whom it may concern.

Be it known that 1, JOHN Tr-ronnxs Kierman, a citizen of the United States, residing at Caroleen, in the countyof Rutherford and State of North Carolina, have invented certain new and useful Improvements in N ut-Locks, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to locks and more particularly to the class of nut looks.

The principal object of the invention is the provision of a nut lock which is cheap and inexpensive to manufacture, and of dudesign.

- A further object of the invention is the provision of a nut provided in one face thereof with a recess adapted to receive'a ratchet disk which is slidably keyed to the eldwithin sai recess through the medium of a locking ring, the ratchet disk being engagedby a spring actuated pawl which when released the nut may be revolved or grooved end'of he bolt and is adapted to be screwed upon the'bolt into various locked positions against rotation in the opposite direction.

"With, these and other objects in view, as will up fitures of construction, combination and arrangement of parts asv will be more fully described hereinafter and set forth with particularity in the appended claims.

Referring to the drawings Figure 1 is a side elevation of my improved nut lock; Fig. 2 is a section on line 2 Fig. 3 is atransverse seetion taken on the line 33 of. Fig. 1'; Fig. t is'a longitudinal 4o sectional view through the nut and'a portion ofa bolt; Fig. 5 is a perspective view of the ratchet releasingmember, and Fig. 6 is a perspective view ofthe locking ring arrangement.

Like characters oif reference are used to denote like. parts "throughout the accom panying drawings andgythe annexed specifi cation. p I

- Referring more particularly to the draw- Sings, the reference character 1 indicates the threaded end portion 'of a belt which may be of any desired construction and is provided with a longitudinal groove 2 which extends throughout the length of the threadpear as the description proceeds, the 30/invent1on comprises the various novel fea- 2 of Fig. l;-

periphery with notches 19.

ed end portion of the bolt. A nut 3 of any design is threadedly mounted upon the bolt 1 for free rotation in one direction. The innor face of the nut 3v is provided with a circumferential recess 4 which is adapted to receive a ratchet 5, the latter being slidably keyed to the bolt 1 through the medium of a key 6 formed at and to. project inwardly of the. central opening of the disk. This key 6 seats within the groove 2 of the bolt where by the ratchet disk 4 may have free longitudinal movement upon the bolt. The pe ri heral edge of the ratchet disk 4 is prov' ed with a plurality of notches 7 to form what might be termed ratchet teeth. The nut 3 is provided at the upper portion there- 0;t',as clearly seen at Fig. 3, with a vertically extending slot 8 through which projects a ratchet pawl 9, the lower end thereof being adapted, as shown at 10, to; engage the rate et teeth 7 of the disk 4. "l.-he ratchet pawl 9 is provided with'a laterally extendmg arm I]; which terminates in an arm 12 formed at right angles to thearm-ll, the angle of connection of said arms being provided withan aperture 13. As shown the nut is. provided at its upper and one side face thereof with a continuous groove 14 in which is arranged the arms 11 and 12. A pivot-pin 15 is passed through the upper corner of the nut and through the aperture 13 whereby the ratchet pawl may have free rocking movement to disengage the ratchetpawl 9 from the ratchet teeth 7 when the pawl 9. is lifted out of engagement therewith for the free rotation of the nut 3 upon the bolt. Secured to the arm 12 is a fiatleaf spring 16 seated within. the lower portion of the recess lt and adapted to exert an outward tensio'n upon the arm 12 to cause theratchet pawl 9 to 'lockingly engage, the ratchet teeth 7 of the disk 4. The-disk 4 is provided with an inwardly extending hearing collar 17 upon which is arranged a looking ring 18, the latter being provided in its The outer edge of the recess formed in the inner face of the nut 3 is constructed inwardly at diametrically opposite points to form locking lugs 20. To arrange the locking ring 18 in position, it is revolved so that the notches 19 aline with the locking lugs 20 whereby the ring 18 may be dropped thereover into the recess of the nut 3 and then revolved so that the peripheral edge of the nut.

the ring engages be 20 whereby the ring disengagement with By the provision of such a locking ring as described the ratchet disk l will be securely held within the nut against disneath the locking lugs will be prevente from placement and yet allow of a free longitudithe forward end of which is flattened and crating member 21 is widened and formed with anopening 23 which is of the same size and shape as the nut 3 whereby the operating member may be arranged over the nut to release the 'ratchet'pawl 9 and to revolve the nut upon the bolt. This operating member a 21 is provided in its side edges adjacent the opening formed in the end thereof with notches 24. That portion of the member between the notches 24 and the opposite side edge of the member is beveled as shown at 25 from the inner edge of the notches 24: outwardly as will be clearly seen by; reference to Fig. 5.

In the operation of t e invention the oplaced over the nut 3 and is pushed inwar g sufficiently far so that one of the bevele faces 25 rides inwardly underthe beveled face 26 formed on the under face of the projecting portion 27 at the up or end of the ratchet pawl 9 be lifted out of whereby t e pawl 9 ma et teeth 7 to allow engagement with the rate 'of a free rotation of the nut 3 in one direction in the removal of the nut from the bolt. When it is desired to screw the nut upon the bolt, the nut is freely rotated in the opposite direction, the lower face 10 of the ratchet pawl 9 having been disengaged from teeth premit of this free rotation of the nut 3 upon the bolt 1.

In Fig. 6 will be seen an-operating member 28 which is provided with a handle 29, the forward end of which is bifurcated or forked to provide spaced arms 30 which have their terminal ends bent at right angles to provide lugs 31. When it is desired to remove the locking ring 18 theoperating member 28 is taken in one hand and the lugs 31' on the end thereof are engaged with diametrically op osed notches 32 formed in the inner circum erential face of the locking r'ng 18, whereby the latter may be revolve so that the notches 19 in t e periphery thereof are disposed. op osite the locking lugs 20 thus enabling t e ring 18 to be moved outwardly of the recess in the nut 3. B the removing of the locking ring) 18 it Will be apparent that free access may e had to the ratchet disk 4.

From the foregoing connection with the accompany nt5 drawings, the advantages of constructionwill the 'said ratchet disk whereby the nut may description taken in method of operation will be readily apparent to those skilled in the art to which the invention relates, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire it to be understood that such changes may be made when desired as are within the scope of the appended claims.

Having thus fully described my invention whatI claim as new is! 1. In a nut lock,-the combination with a 'bolt provided with a longitudinal groove, a-
