NUT-LOCK.
SPECIFICATION forming part of Letters Patent No. 561 ,77'6, dated June 9, 1896.
Application iiled December 7,1895. Serial No. 571,365. (No model.)
To all whom it may concern.-
Be it known that 1, JAMES A. EivsLEY, a citizen of the United States, and a resident of the city of Covington, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Nut-Locks, of which the following is a specification.
The several features of my invention and the various advantages resulting from their use, conjointlyor otherwise, will be apparent from the following; description and claims.
In the accompanying drawings, making a part of this application, and in which similar letters of reference indicate corresponding parts, Figure l is aview in perspective of a bolt and nut and locking-key constructed according to my invention. Fig. 2 is a viewin perspective of the locking-key, shown on an enlarged scale. Fig. 3 is an end view of the nut. Fig. 4. is an elevation of the bolt and a vertical central section of the nut and an edge view of the key, these parts being locked together and showing a mode of applying the key to the bolt. Fig. 5 is an elevation of the bolt and a vertical central section of the nut and elevation of the key and illustrating a mode of using the key when the end of the bolt remains in the nut when the latter is in place. Figs. 3, 4t, and 5 are on the same scale as Fig. 1. Fig. (3 is a view in perspective of a nut and a punch constructed by me to form the nut according to my invention. Fig. 7 is an elevation of the end portion H of the bolt.
1 will now proceed to describe my invention in detail.
A indicates the bolt. This bolt may vary in size and shape, and the head portion B may be of any desired configuration. That end ll of the bolt which is opposite to the head is screw-threaded. .This screw-thread C may be of any desired pitch and size. A nut D is provided and therein is formed a screw-thread E of a kind suitable to engage The shape of a monkey-wrench or similar form of wrench is to be employed and applied to the edges of the nut to turn the latter the latter will have a requisite number of flat sides, as F, on what would otherwise be denominated the periphery of the nut.
To apply my invention, I provide a groove G across the end H of the bolt. This groove may be formed by raised flanges or ridges, but is preferably formed by cutting into the metal of the end of the bolt, as shown. Such a mode is more advantageous, as it economizes metal and is more readily and cheaply carried into effect. In the nut I form a receptacle for the key K. In application one end of the key isheld by the nut screwed onto the bolt, and the key is then bent or moved into the groove in the end llof the bolt.
A novel and advantageous mode of holding the key consists as follows: 1 form in the nut a groove M, interrupting the screw-thread of the nut at the point where the screwthread is present, the groove being parallel, or substantially so, to the axis of the screw-hole of the nut, and to prevent the key from slipping forward lprovide it with a head K A cheap and convenient mode of forming this head consists in bending up one end of the straight piece which is to form the key. The keypiece preferably fills the groove M to or nearly to the plane where the threads of the bolt would come.
here the key K with head K is employed and it is desired the head shall not project beyond that side of the nut which is toward the head of the bolt, I provide a recess M in the nut at the end of the groove M, as shown, for the reception of said head of the bolt. If this recess were not present and the head K were present outside of the nut D and between the latter and the head of the bolt, the head would take up valuable room and abbreviate the valuable working port-ion of the bolt.
In applying my perfected invention in its most advantageous form I proceed as follows The belt is applied to connect those parts of the splice, union, structure, or mechanism for which it is designed or utilized. The key K is then placed in position in the groove M of the nut and its head K is located in the recess M The nut is now screwed onto the bolt and screwed home, thereby performing its functions of holding together the parts it was designed to connect. The key K, except its head, is thus far straight, and it is of some non-elastic material, the preferred material being a non-elastic metal capable of being readily bent. That part of the key projecting beyond the end H of the bolt is now bent down into the adjacent groove G of the bolt, substantially as shown in the drawings. \Vhere the end H of the bolt projects beyond the adjacent face of the nut, the free end of the key is preferably bent around the end of the bolt, as shown in Fig. 1; but in other cases the preferred length of the key beyond the nut does not exceed the diameter of the bolt. Then the key can be readily bent into the groove G of the bolt whether the faces of the end of the free end H of the bolt and the back side P of the nut are in the same plane (seen in Fig. at) or the end of the bolt is within the nut, (see Fig. 5,) the bolt in the latter case being somewhat short.
The bolt can be unlocked byhuman agency properly and intelligently applied to unlock it, but will be thoroughly locked and the nut will not unscrew through vibrations of the parts nor by force (Within reasonable limits) brought to bear against or in connection with the faces or periphery of the nut.
It will be observed that the construction of my lockin g device in connection with the bolt and nut is simple. My device is obviously cheap and economical of construction and of material. The invention is easily applied and effective in function and advantageous in results.
As before indicated, my invention is applicable to the nut and bolt whether the end of the bolt projects beyond the face P of the nut or is flush therewith, and, being short of length, remains within the nut.
When desired, more than one transverse groove G may be present in the end of the bolt. Such increase in the number of grooves will rarely be necessary, except in cases where great nicety of adjustment of the coupling union is required.
Fig. 6 illustrates a means and mode of forming the groove M and recess M R in- 1 dicates the punch, having a shank R of size to form the screw-hole of the nut. At one side of the shank and longitudinal therewith is a fin or raised portion R and farther back on the portion R is another fin R, whose outer edge or back extends still farther out from the axis of the punch than does the back of portion R When the punch is made to operate on the blank which is to form the nut, the shank R punches out the main hole and the raised portion R punches out the groove M and the fin It makes the recess M the punch stopping after the fin R has advanced far enough into the iron of the nut-blank to form said recess M Fig. 6 shows the nut as having been already operated upon by the punch. This operation indicates the simplicity of the operation whereby the groove M and recess M are formed simultaneously with the screw-hole of the nut.
What I claim as new and of my invention, and desire to secure by Letters Patent, is
1. In anut-lock, the combination of the bolt having the end transverse groove, and a nut having the groove M, and the recess M at the end of the groove, and the key havingthe head adapted to fit the recess M while the key fits into the groove, and is bent so as to interfit the groove of the bolt, substantially as and for the purposes specified.
2. In a nut-lock, the combination of the bolt having end groove, and a nut having groove M terminating in recess M and a headed'key K, K whose head fits in the recess M and a part of its shank lies in groove M, and a portion of its shank is bent down into the boltgroove, and a remaining portion bent back on the other side of the bolt from where the key lies in groove M, thereby forming an embracing-clasp, substantially as and for the purposes specified.
3. In a lock, the combination of a bolt A, having the end portion H serew-threaded with thread 0, and having a groove G at, in and across the extremity of the end portion H of the bolt, and a nut D having an interior thread E registering with and engaging the thread 0 of the bolt, this nut having a transverse groove M extending from the front to the rear of the nut, interrupting the screw-thread of the nut and an enlargementof the groove M in the nut and at the rear of the groove (toward the bolt-head) and a key having a head I, fitting in the said enlargement of the groove M, and extending forward in the groove M, and forward along the bolt, and at the end of the latter extending across the end of the bolt and located in the end groove G thereof, substantially as and for the purposes specified.
4. In a nut-lock, the combination of a bolt A having the end portion II screw-threaded with thread 0, and having a groove G at, in and across the extremity of the end portion H of the bolt, and a nut D having an interior thread E registering with and engaging the thread 0 of the bolt, the nut D having a transverse groove M extending from the front to the rear of the nut, interrupting the screwthread of the nut, and a vertical recess 3 in the rear side of the nut and joined to the groove M and extending radially out beyond the groove, and a key K having a head K at right angles to the axial line of the bolt, and fitted in the recess M of the nut, a portion of the shank received in groove M, and a portion bent across the threaded end of the bolt and at right angles to the length of the latter and received into the groove G in said end, substantially as and for the purposes specified.
