OLINCIHING NAIL.
Application filed February 10, 1325. Serial No. 8,102.
This invention relates to clinching nails and it has more particular reference to nails for use in the shoe making, repairing and leather industries. .At present, clinching nails employed in the arts referred to may be generally classified as of two varieties: namely :Iron cut nails fabricated from bar stock with a sharp point that lends itself to quick application to leather; and nails made from wire which clinch when driven into leather and naturally hold securely. The former type of nail,'as a result of its sharp point, penetrates leather by slight pressure thereby enabling it to be quickly driven, but it has a tendency to break-on easily due to its inherent lack of pliability. Another disadvantage is that iron out nails do not clinch readily and hence are lacking in security. lVire nails, on the other hand being more pliable do not break-off easily, but they possess the disadvanta e of not being sufliciently penetrative Ior quick driving with an attendantloss of time and labor, as they must be set, or given an initial start, be fore being driven.
My invention has for its primary object I to provide a clinching nail embodying all the advantages of the above referred to types of nails with none of the stated disadvantages.
Other objects and advantages inhering to this invention will be later on referred to, and it may be tersely defined as consisting essentially in fabricating a relatively short er shanked nail from wire with a comparatively longer sword-section point, which clinches with a distinctive curl when driven thereby ensuring a much firmer hold.
The accompanying sheet of drawings typify an advantageous embodiment of this invention such as is particularly serviceable in the shoe making and repairing industries, 'while the appended claims succinctly recite the subject-matter believed to be novel.
In the drawings Fig. I is an enlarged view of a clinching nail embodying the characteristic features of this invention.
Fig. II is a view at right angles to the preceding illustration; and,
Fig. III is a transverse section taken as indicated by the arrowsIIIIII in Fig. II.
Referring more in detail to the drawings, and bearing in mind the above recited ob jeets, my nave of clinching, nail,
prehensively designated by the numeral 5, is made from metal wire of suitable gauge cut into predetermined lengths. Each length is fashioned in any of the well known ways to provide a head 6, shank 7, and relatively longeror majorpenetrative portion 8. This latter portion 8 is what constitutes tie fundamental of my invention, hence particular attention is directed to the distinctive contour and cross-section thereof. As shown, it will be observed. the penetrative portion 8 is of sword cross-section to provide diametrically opposed cutting edges 9, 9, and relatively stiffer or blunt edges 10, 10, at right angles thereto; all of said edges gradually merging from the shank 7 towards the nail tip or point 11. It is also noteworthy that the nail faces 12 intervening the aforesaid edges 9, 10, are longitudinally concaved to assist the penetrative action.
From the foregoing it will be clearly understood that the relatively long sword-section penetrative portion 8, of my improved nail, lends itself to easy application to leather by a mere pressure on the head 6, whereupon it can be quickly driven without clanger of springing back. while its penetrative action is clean cut. Nails 5. of the section set forth herein will be found to clinch with a distinctive curl when driven into leather upon a last or other non-penetrative surface ith a consequent better hold. Again my improved nails 5, having a shorter shank 7, with a correspondingly longer penetrative portion 8, than any others at present in vogue for anala rous use will drive into leather more easily because fully one half thereof acts as a cutter, while being hammered into said leather. Still further I find that my improved nails clinch with less of a hump orbulge than others, heretofore in use, as a natural result of the thinner pcuetrative section.
Obviously, detail changes relative to the proportions of the respective parts of'my novel clinching nail may be effected, with out departing from the fundamental features involved, accordingly the right is hereby reserved to make such variations as are fairly encompassed bythe appended claims.
Having thus described my invention, I claim l. A wire clinchin nail having the major portion cf its cf seord hlade section to afford longitudinal blunt and cutting edges respectively lying in planes at right angles to each other, said cutting and blunt edges gradually merging to the nail point.
2. A Wire clinching nail having the major portion of its shank fashioned to swordblade cross section thereby afiording opposed longitudinal eutting edges and 0pposed blunt edges with intervening concaved faces, said cutting edges and blunt edges gradually merging toward the point of the nail.
3. A clinching nail fabricated from a length of wire to provide a headed shank and a penetratii'e portion of relatively greater extent said penetratii'e portion being grooved to sword-blade cross section thereby providing opposed longitudinal cutting edges and opposed blunt edges eat-h having a decreasing merge from the shank into the nail tip.
In testimony whereof. I have hereunto signed 111 name at Allentown. Pennsylvania, this 5th day of February, 192:3.
JAMES H. DOBBS.
