SPECIFICATION forming part of Letters Patent No. 776,676, dated December 6, 1904.
Application filed April25, 1904. Serial No. 204,748. (No model.)
To @ZZ wlw/n, t may carl/cern,.-
Be it known that l, JnIiEMIAI-i UMEARA, a citizen of the United States, residing' at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Nut-Locks, of which the following is a full, clear, and eXact description.
This invention consists of a bolt, with or without a screw-thread, having' a transverse longitudinal slit in its end, in which a tongue of metal having' an appropriate base is lixedly secured by closing the metal of the bolt about it, the projecting end of said tong'ue adapted to be bent over and upon a nut, washer, or other device, whereby the bolt and its nut or washer are secured in positionag'ainst accidental displacement.
While lY have entitled iny invention a nutlock, l wish to be understood as including1 within that term any substitute for a nut, such as a washer, used to assist in fastening' inaterials Vtogether by means of the bolt.
1n the accompanying drawings, illustrating the invention, in the several lig'ures of which like parts are similarly designated, Fig'ure l is a side elevation of a bolt without a screwthread. Fig. 2 is a perspective View of one form of tongue. Fig'. B is a side elevation of the bolt of Fig'. l with the tongue inserted. Fig'. 4. is a sectional elevation of a bolt of the character shown in Fig'. 3 applied to two pieces of material in connection with a washer. Fig. 5 is a View similar to Fig'. 4.-, showing' a bolt provided with a screw-thread and a nut. Fig. 6 is an elevation of a bolt having one end screw-threzuled and supplied with a fastening'- tongue and the other end made without a head and supplied with a fastening-tongue as a su bstitute for the head. Fig. 7 is an edge view of a niodiiied form of tongue. Fig. 8 is a similar view of another modilication. Fig. 9 is a face view of still another niodiiication of the tongue.
As shown in Figs. 1 to ll, the bolt l has a head of usual construction. In its point, which is without la screw-thread, a transverse longitudinal slit 2 is made. 3 is a tongue, preferably having' a wedge-shaped base 4, which wedge-shaped base is inserted in the slit 2, and then the metal of the end of the bolt is closed about the wedge-shaped base of the tongue, so as to iixedly attach said tongue to the bolt. Such a bolt is applied in an appropri ate hole in materials to be fastened, and a washer 5 is placed over it, and then the tong'ue is turned down over the washer, as shown in Fig. 1-, thus securely fixing the bolt in and uniting' the material. If, however, the bolt be screw-threaded, as at 6, Fig. 5, then a nut 7 may be applied to the-screw-thrcad and the tongue turned down over the nut. If desired, the tongue may be niade long enough to be turned down over the side of the nut as well over its face.
As shown in Fig. 6, a headless bolt may be made in accordance with iny invention, and in that case the bolt S may have one end screwthreaded, as at 9, to receive a nut which is locked in place by the tongue 3. The other end l() of the bolt is similarly slit and provided with a tongue 3 to be turned down over a washer or directly against the material to which it is applied as a substitute for a bolthead.
As shown in Fig. 7, instead of making the tongue with a wedge-shaped base' such base may be roug'hened, as at 1l, or, as shown in Fig'. 8,the base 12 may be crimped, or, as shown in Fig'. 9, the base may be provided with one or more holes 13, intowhich the metal of the bolt may be squeezed.
In any case where the bolt is screw-threaded it is preferred to cut the thread after the tongue is in place, so that that portion of the tongue within the bolt may be threaded as well as the bolt itself.
As already stated, the invention while entitled a Lnut-lock includes in its purposes and uses a bolt-lock as well, and it is susceptible of other modifications than those specifically illustrated. ln the caseof the headless bolt it is obvious that both ends may be screw-tln'ezuled to receive nuts or both ends may be threadless.
By these several constructions a very simple and efficient as well as strong and durable nutlocl or bolt-lock is provided.
That Iclaini isl. A nut-lock, col'nprising a bolt constructed with a transverse slit extending in the dii'ection of its length, and a flexible tongue IOO having a base inserted in said slit and interlocked vwith the Walls of said slit and lixedly 3. A nut-lock, comprising a bolt having a transverse longitudinally-slitted end, and a I5 tongue inserted in said slit and fxedly secured therein, the slitted end of the bolt and the portion of the tongue Within it being externally screw-threaded.
In testimony whereof I have hereunto set 20 my hand this 22d day of April, A. D. 1904:.
J EREMIAH OMEARA.
