UNITED STATES PATENT OFFICE.
JOHN HARE, OF WILMINGTON, DELAVARE, ASSIGNOR TO THE MORGAN NUT LOCK WASHER COMPANY, OF SAME PLACE.
MANUFACTURE OF NUTS AND WASHERS.
SPECIFICATION forming part of Letters Patent No. 351,978, dated November 2, 1886.
Application filed August 12,1886. Serial No. 210,07 (No model.)
To aZZ whom it may concern.-
Be it known that I, JOHN HARE, a citizen ofthe United States, residing in Wilmington, Delaware, have invented certain Improve- 5 ments in the Manufacture of Looking Nuts and Washers, of which the following is a speci fi cation.
My invention relates to the manufacture of that class of locking-nuts in which two nuts I: are employed, and in which the nuts are constructed to engagewith each other, so as toinsure their turning together in screwing them up on the bolt, the object of my invention being to provide for the rapid and economical manufacture of nuts of this character.
In the accompanying drawings, Figure 1 is a perspective view, and Fig. 2 aplan view, of a bar for the manufacture of nut blanks in accordance wit-h my invention, the dotted lines showing how the bar is punched to produce the nut-blanks. Fig. 3 is a perspective view of alocking-nut constructedin accordance with my invention; Fig. 4, a plan view of the same with the second nut inplace thereon; Fig. 5,a section on the line 1 2, Fig. 4'; and Figs. 6, 7, 8, 9, and 10, views illustrating modifications of my invention. 7
A locking-nut has'been heretofore devised in which a nut, A, of the usual character, is combined with a supplementary nut, A, constructed to engage with the main nut and to turn therewith in screwing the nuts up on the bolt, the main objection to compound nuts of this character, as, heretofore constructed, being the expense of manufacture, for the nut A has usually been constructed with a rib entirely surrounding the nut A, or the latter has been formed with .a recess in its face for the reception of the nut A, the ribbed or recessed nut in either case having to be formed by forging or casting the same-operations which are attended with such expense as to render them impracticable. In carrying out my invention, therefore, I make the ribbed nut by first rolling a bar, B, of any desired length, and having on one of its faces, preferably at each edge, a rib, a, asshown in Fig. 1,-the nut being then punched from this bar by an ordinary punching-machine,which is preferably so constructed as to form at the same time the central opening in the nut, as indicated by dotted lines in Fig. 2. All that then remains to be done in order to complete the nut is to form the thread in this central opening, as shown in Fig. 3, the nut A fitting between the oppo- 5 site ribs, a a, so that the two nuts are compelled to turn together in screwing them up on the bolt- There is always more or less space,
however, between the adjoining faces of the two nuts, and it is to this space that the locking is prevented from moving farther forward on the bolt, it'follows that there is such a jam- 7o ming or binding of the threads of said nut A. against the threads of the bolt 'as will effectually prevent any subsequent accidental loosening of said nut A, or of the nut A, which is circumferentially confined thereto.
By making the nut A of circular form and of a diameter equal to the diagonal axis of the nut A, said nut Awill turn in the same space as the nut A, this being a point of considerable advantage when the nuts are to be used in contracted spaces. It should be understood, however, that my invention is not limited to the making of the nut in this circular form, as the bar B may, if desired, be severed transversely,
so as to form a square nut of the character shown in Fig. 6, or the nut may be of hexagonal form, as shown in Figs. 7 and 8, the nutA in this case, however, being, by preference, recessed, as shown, for the reception of the ribs a of the nut A.
My invention might, if desired, be adopted in'the manufacture of the main nut A, (shown in Fig. 9,) the nut Ain this case being in the form of a simple flat plate, adapted to fit between the ribs a of the nut A; or, instead of forming continuous ribs (1 upon the bar B, the rolls for forming the latter may be so constructed as to produce lugs a at intervals upon the face of the plate at each edge, the bar being afterward severed and punched, as shown roo by dotted lines in Fig. 10, to form the nutblank; or, as before stated, the bar may have a rib or projection at one edge only, two ribs, however, being preferred.
I claim as my invention- 1. The mode herein described of forming a locking-nut, said mode consisting in first rolling a bar having a rib or projection upon one face at or near the edge, and then punching the nut blanks from said bar and threading the central openings of said blanks, all substantially as specified.
2. A lock-nut having a central threaded opening and projecting rib upon one face, two diametrically-opposite portions of the nut being without ribs, all substantially as specified.
JOHN HARE.
