SPECIFICATION forming part of Letters Patent 110.243,602, dated June 28, 18-81.. Application filed February 4, 188i. (No model.)

Be ithnown that I, Aart-Ina NEWTON, of Boston, in the county of Suti'olir and State of Massachusetts, have invented certain Improvements in Shoe-Nails, of which the following is a specicaticn. v

This invention relates to chisei-poin ted 'nails' for fastening the soles ot' boots and shoes, and it has for its object to provide a naii' which may be readily formed from a con tinnous length of wire, and embodying certain improvements rendering said nail less liable-to be loosened after it has been driven than is the case with To accomplish this object I have devised a nail of the form I will now proceed to describe, reference being had to the accompanying drawings, forniing part of this specification,l in which- Figures l and 2 representa con tinnous length ingmy invention. Figs. 3, 4, andl represent 3a represents a top view of a nail'. lFig. 3" reprecents a section on line aux; andgItig. 3 a section on line y y, Fig. 3. All theig'foregoing gnres are considerably'T enlarged. ,'i

rIlne same letters of reference indicate the same parts throughout.

In carrying out my invention 'I subject a continuous length of wire, W, (said wire being square in transverse section) to the action of suitable notcling mech anism, forming a series of notches or indentations, n, on the angles of the Wire. The wire W is afterward fed through proper guides and subjected to the action of reciprocating knives or cutters, by means of which I form elongated notches n' diagonally with the main body of the wire at intervals corresponding to the requiredzlength of a nail, thereby forming diagonal ehiselpoints on each nail N, and at the sanne time forming the head the succeeding nail. forming the notches n do not entirely sever the wire, but leave a small portion of its centeriniact, thus adaptin g the wire to be afterward readily separated, forming independent nails, 11s-shown in Figs. 2, 3, and 4. The indentations n formed upon the angles of the Wire may be either square, isi-shaped, or of any desired form, three different patterns being shown in the drawings; and I prefer to vin driving,`

form these indentations so thatthe indentations on two of the opposite angles of the wire will alternate with those on'the other two opposite angles thereof, as by forming the indelitatious in this manner the nail afterward formed from the wire is rendered less liableto' turn or work loose than it' said indentations werle opposite tc each other entirely around the nai e 2 By forming the chisel-points diagonally with the main body of the nail I produce a greater number of angles and resisting-surfaces on the naii than would bethe case if the point were formed on the sides of the nail, inasmuch as the lower part of the nail is renderedhexagonal, while the upper part retains its square form; and' by forming the .points diagonally it is possible to carry the indentations on two of the opposite angles ot the nail entirely to the point thereof. These advantages cannot be obtained in the ordinary round-pointed nail.

Each series of notches 'n is separated from the adjacent series by the intervening smooth surface or sides of the nail, the notches u extending only partially across the sides, as shown. By thus separating the series of stitches by intervening smooth surfaces the leather adjacent to the sides of the nail is left undisturbed and thenail is less likely to become loosened on turned-:than is the ordinary square nail corrugated all around,or the threaded nail, as in driving such nails the leather is more or less torn entirely around the nail.

In operation, as the nail is driven .the leather displaced bythe nail settles into the indentaiy tions n formed upon the angles thereof, and the, solid portion of the nail over each set of indentations acts as ahead, preventing the nail from working loose,

ventedvfrom turning or suerin g displacement sidewise by the leather adjacent to each side re- Y' mainin g undisturbed, as previousl y described,

the nail being pre.

chisel-pointed or IOO is homogeneous, its substance being left intact in forming the nail, which is not the case when metal is carriedl down'from the point of one ,nail toform the head-of the next, or whenan enlargement is formed on the wire to produce the head of a nail. A

In another application for Letters Patent now pending I have described-and claimed a nail angular in transverse section, having a series of ndentations or notches formed in each of its corners or angles, each series of notches being separated from the adjacent series by f intervening smooth surfaces of the nail.; hence Iclailn',

I do not cla-im such a nail, broadly, in this application. A

Having thus described my invention, what and desire to secure by Letters Patent,

1. A nail or sole-fastening composed ot' wire angular in transverse section, having a series of indentations or Vnotches formed in each of its corners orangles, (each Aseries of notches bevtransverse section, having a seriesf-indenta- 3o tions or notchesforned'in each of its-'corners or angles, (each series of notches being sepa- `rated from the adjacent series by-intervening smooth surfaces orsidesof the wre,) and lchiselv points form'eddiagonaliy with the body of the 3 5 nail, substantially as shown and described.l

In testimony whereof I have signed my name .to this specification, in the presence of two sub-A scribing witnesses, this 2d'day of February,-
