LOCK-NUT DEVICE.
. V Specification of Letters Patent.
Patented Sept. 2, 1919.
I Application led May 13, 1918. Serial No. 234,274.
To all whom it may concern:
Be it known that I, HARRY SGHOFIELD, of 117 and 118 Leadenhall street, E. C. 3, London, England, am the legal adminisd trator and eXecutor of the late SIDNEY JOHN Ross, of the same address, who invented certain new and useful Improvements in or Relating to Lock-Nut Devices, of which the following is a specification.
This invention has reference to lock-nut devices which have an eccentric locking action and in which one vnut has a plug or spigot part projecting into a recess or socket in the other, the two nuts being connected together to form one unit or device.
This invention provides not only an ec centric grip action of the spigot in the socket but retains also the ordinary locking or jamming action of the back-nut against the main nut. Thus the two locking actions supplement one another, giving a double locking. Moreover the eccentric action is obtained in a simple manner by making the bore or eye of the device eccentric. The nuts are so connected that there is between them a slackness or lost-motion equal to a definite fraction of the pitch (say a third or half the pitch of the screw-thread), and also a corresponding gap between the internal threads of the said nuts.
One example of construction is shown in the accompanying drawings.
In these drawings Figure 1 is a side-view, and
Fig. 2 is a vertical section of such a locknut device.
Fig. 3 is an enlarged fragmentary view hereinafter referred to. v
a is the main nut and b the back-nut or jam-nut of the improved device.
0 is a recess or socket in a, which receives j a plug or spigot d on b.
al and b1 are respectively the screwthreaded eyes or bores, which according to the invention are eccentric to the nuts themselves.
This eccentricity causes d to bind or jam (in the known manner) in c if the back-nut Z) is turned relatively to a.
e is a groove or recess formed around the top of the plug or spigot part d (see Figs.
2 and 3), to receive the bent-over edge f1 of" a wedge-like lip f around the mouth of the socket o'.
Before the device is screw-threaded, the
nuts are forced down on to each other until the top of the groove e bears on the edge of the lip f (see Fig. 3) and presses, curls or clenches it inward as indicated at f1 in dotted lines. The lip now projects laterally into the groove in the parts b d, and thus prevents the nuts becoming separated or detached, although they can still turn relatively to each other. The distance between the bent edge f1 of the lip and the bottom edge e1 of the groove c, should be about equal to the gap g below the plug d.
One or more distance ieces c' (Fig. 2) may be'inserted between t e nuts to prevent them being pressed closer together than is required to bend the edge f1.
In practice the plug or spigot d and the i socket c can be easily cut concentrically with the nuts on a lathe, and the undercut groove c and lip j' formed at the same time. The two nuts a b, are then put under a press and the lip f clenched over at f1 as described. The said nuts (now forming one unit) are then bored or tapped eccentrlcally as at a1 b1 from the bottom end, that -is to say from a toward b at one single operation thus simplifying the manufacture, in contrast to making 0 and (Z eccentric. The lip f1 limits the distance of the nuts at this time, and the thread in the bore a1 (in spite of the gap at g) is an eXact Acontinuation of that in the bore b1.
The marks h, are then applied to the nuts, and when opposite each other show that the threads a1 b1 match or correspond exactly.
The arrangement is such that when the nuts are on a bolt with the marks h in line they can be screwed up freely like one single nut. If b is then turned relatively to c, it will close the gap g and set up an ordinary lock-nut action, at the exact moment at which the part d turning in the socket, sets up a circumferential binding or gripping ac tion due to the eccentricity.
This eccentric action should for instance be completed in one-third of a turn, if the gap g equals one third of the distance bean tween the screw-threads. Thus the two locking or jamming actions eifectually supplement each other, and a double locking action is obtained.
1 claim z- 1n a double action lock-nut device, the combination of two eccentrically bored and threaded nuts, one of said nuts having a concentric socket and the other having a concentric plug fitting in' said socket, said first-named nut having a tapered conical lip around the mouth of said socket, the other of said nuts having a oove at the root of said plug to receivesald lip and allow end- 'Wise play, and said nuts having marks to indicate the proper relative position Where the threads match and both nuts screw on 10. simultaneously like a single nut, the nuts 'having at such time afgap between them which is closed when the back nut is given the necessary eXtra turn to cause the ecccntric locking action, substantially as dcscribed.
In testimony whereof I affix my signature.
HARRY SCHOFIELD, Administrator and executor of Sidney J 07m,
Ross, deceased.
