ART or MAKING HEXAGQNAL NUTS.
Application filed August 13, 1912.
Specification of Letters Patent.
Patented oer. 2i. 1 e13.
Serial no. 714.825.
To all whom it may concern:
R itknown that I. Fnxxx l). TIDEMAN a citizen of the United States. residing at Brooklyn. in the county of Kings and State of New York, have invented a new and useful Im rovement in the Art of Making Hexagona Nuts, of which the following is a specification, reference being made therein to the accompanying drawings. I
This invention relates to a novel method or process including the making of peculiar blanks from round. or approximately round. metal rods. and transforming; the same into hexagonal nuts; the object being to afford a simple and expeditious met-bod of manufacture; to avoid waste of material, and to reduce the cost of production of said class of nuts.
In the accompanying drawings, Figure 1 represents a plan view of a piece of round rod stock, and shows the manner of forming the blank therefrom. Figs. 2 and 3 represent a side View, and end View. of the primary blank, as severed from the rod or bar. Fig. 4 is a cross-section at line X (on Fig. l or Fig. 2) and Fig. 4 shows a similar cross-section of a hlank-stockrod which is oval or approximately round; a suit-able shape, but not of exactly circular cylindrical cross-section. /I ig. 5 represents a transrer e section otthe blank, as flattened "r'ron'i 'rts cylindl cal form, or as rendered at the second stage of the transforma t on. and Fig. 6 is a'jplan view oi the same. Figs. 7. 5% and 3 represent. respectively, a side. section and plan views of the nut as at the third step in the process of manipulation. and Fig. 10 illustrates the finishing or pei'festi.;:;-nt of the peripheral edges of the conupletely shaped nut.
in my improved method of makinghex'agoual nuts i use. as a tock material therefor, metal bars or rods 1 of round shape, cylindrical or approximately cylindricalcrgss-section. and of a diameter somewhat greater than the length of one hexagonal side of the required nut; this proportion being somewhat variable, more or less, for different thicknesses of nuts. 'From the round rod of stock. Fig. 1, a peculiar blank 2 is formed by severing therefrom a portion of suitable length. by opposite V-shaped lateral incisions 3- entering the sides of the rod and meeting at the central axis, thus producing a blank. having a cylindrical or approximately round cross-section, and wedge shaped angular ends 3, the line 5 of the angles bein upright. thereby giving to the blank an approximately hexagonal contour horizontally. The severance of the round rod 1 by a V'shape incision condenses or upsets some of the metal at the outside edge 4 and stretches or draws the metal more or less near the bottom of the V. The 86V ering of the rod'to form the blanks 2 can he etiected by various means, one practical way of doing it is to employ oppositely approaching wedge-shaped cutters 6 meet ing, ornearly so, t the central axis of the rod; the rod being intermittently adjusted endwise forthe length of each succeeding blank as the blanks are separated therefrom. This primary blank 2 is next placed in a suitable hexagonal die or matrix Where it centrally confined by its angular ends 5, coinciding with two opposite corners of the hexagon, and is there flattened upon its top and bottom convex or rounded surfaces 7 and 8. or conipres: I in the direction of the line 5 at which the inclined end SUI? faces meet. Preferably, and at the same time a beveled or cup-shaped depression 9 is centrally formed in each of the flattened surfaces (SQQ FlfIfS. 5 and 6). This second step brings the blank into a flat, practically hexagonal form as an embryo nut 2*. The next step in the process is to stamp the upper and lower flat-faces 7 and S with the crown-bevel or chamfer l0. and to punch through the central opening or eye l2 with in the depression 9. giving theconiplcte nut. form shown in Figs. 7, and 9. The nut 22 is then passed through a broaching or n gin operation, 'as by punching it through a cutting edged gage-die 13. for removing any irregularities or bur that may have been formed thereon. and for squaring up and perfecting the sides to a true hexagonal shape. The threading of the eye. 12 may be done in usual manner.
I do not claim broadly, the idea of utilizing' a cup-shaped recess as a preparatory impression for the eye in the construction of nuts, as I am aware that such recesses have heretofore been adopted in a different method of manufacture.
In some instances the forming of the central cup-shaped depression 9 may be omitted, as the forming of the eye 12 could be effected without said recess. But I prefer to make the recesses as a part of the second step. since they serve to render the forming of the eye easier; and also give a slight bevel or counter-bore at the edge of the eye.
By the within described method or rocess hexagonal nuts may be economical y and practically made, and with comparatively very little waste of material in their manufacture while they are produced from round, or approximately round, rod-stock.
lrVhat I claim and desire to secure by Letters Patent, is
1. The improvement in the art or process of making hexagonal nuts, which consists in producing a blank dir' from a rod or bar of round or approxiz round crosssection, by iateral V-sha-pe n isions at the opposite sides of the rod and meeting at the center thereof, compressing and flattening the convex upper and lower cylindrical faces of the blank and at the same time forming central circular depressions in said flattened faces, then stamping the upper and lower faces to form the crowning bevel, and simultaneously punching out the central eye, and subsequently perfecting the gage of the hexagonal facets.
2. The method of producing hexagonal nuts, which consists in primarily forming directly from a round red, by opposite V- shaped severance thereof, an approximately cylindrical blank having angularends and approximately hexagonal outline, placing said blank in a hexagonal matrix with its angular ends fitting in opposite angles thereof, and flattening the upper and lower convex faces, stamping said upper and lower flattened faces to form a crowning bevel, and the central eye hole, then shav ing the hexagonal faces to perfect gage and subsequently threading the eye.
3. In the art of'making hexagonal nuts, the method which consists in producing a primary blank directly'from a round orapproximately round red by oppositelydirect- 'ed wedge-shaped incisions that condense or upset the metal at its exterior opposite sides and stretches and parts the metal along its medial line, thereby providing a transversely cylindrical blank having obtuse Wedgeshaped ends; and subsequently fiattening the convex upper and lower faces and spreading laterally said cylindrical contour into a hexagonal form.
Witness my hand this 10th day of August, 1912.
