WIRE NAIL. d f V SPECIFICATION orming'partcf Letters Patent No. 376,791, dated January 24, 1888.

Application tiled September 27, 1886. Serialy No. 214,673. (No model.)

To all whom, it may concern:

'railroad-spike. Fig. 5 are like views of a threesided blunt-edged railroad-spike. Figs. 6 and 7 are like viewsfof an oval-bodied 'railroadspike. Fig. 8 are details of a three sided nail or spike with chiselpoint. Fig. 9 are details of a three-sidedcurved-line or wedge-pointed nail or spike. Fig. 10 are details of a bluntedged three-sided curved -line or wedgepointed nail or spike. f

The object of my invention is to produce a new and improved style or class of nails orv spikes; and it relates, generally, to that classi: fication commonly distinguished as Wire nails.77 The peculiarly strong feature of it is, that I produce a nail from wire which, from its peculiar form, possesses the one particular attribute and property not possessed by any other wire nail, to my knowledge, which is most desirable and essential in a nail, in that my nail, although straight-sided, will draw inthe same manner and substantially to the same extent as the common wire nail.

A is 'my nail or spike, constructed with a body, 1, head 2, and point 3. rIhe body of this in .cross-section.

nail or spike in its general form is triangular This triangularity may be varied as to the Width of the three main facesthat is to say, they may all be of equal width, or two may be equal and the third one either wider or narrower than the othersor all three -maybe of unequal width; also, these faces may meet each other witha sharp edge; or, as

shown in Fig. 2, they may meet abruptly,form

with teeth, either sharp or blunt, standing at any desired angle o'f presentation, andl these`l or blunt, maybe plain and smoothdorcorru- ,n 'gated-With rough or smooth indentations, or

corrugations or teeth may extend for any desired distance. The heads of the nails are also j* of general triangular form and outline, corresponding generally to the triangularity of the 1 The heads of the railroad-spikes illustrated are usually made of the ordinary form, with, the projecting lip to lap onto the flange of the rail. The points are in general construction Y adapted to present upon one, two, lor three' sides (or more) a triangular, or vsubstantially p triangular, face or faces to venter 'the wood,

lying at any desiredV angle to the body face or faces; also, these triangular point-facesmay be straightsided, or may have'one straight and two of them curved, or all three may bey curved; also, the general line or direction of v any or all of these point-faces may be either straight or curved, as it extends back from the point or apex of the point to the body. When the lines of the point-faces are icurved all in the same curve from the apex of thepoint back to the body, the-meeting lines of these faces, forming the edges of the point, will also be'curved, and when so constructed I'create what I term a curved-line pyramidal point,77 l to distinguish it from a point in which the edges straight. Fig. 10 illustrates this curvedlin'e pyramidal point; also, the points may be pyramidal, as shown in Fig. 2, or wedging, as shown in Figs. 6, 9, and 10, or chisel-shaped, as shown in Fig. 8. Y

In Figs. 8, 6, and 7 I show a nail or spike constructed with a body oval or elliptical iny cross-section, to which I apply my principle of triangularity in the faces of the point.k Y

What I claim as my invention, and desire to securefby Letters Patent, is

A nail' constructed with a three-cornered as shownand described.

ypyrainidal faces are plane and their meeting In witness whereof I have hereunto-set my hand this 17th day of September, 1886.` 7
