page_text: Manufacture of Boots and Shoes.
I, WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
This invention relates to nails chiefly designed for use in the manufacture of
boots and shoes.
Nails for use in uniting leather work, as, for instance, in securing the soles or
heels of boots or shoes to their uppers, and which are made from a continuous
wire, by having one or more of their sides flattened for a portion of their length
in order to form at one end tapered shanks to be driven into the material used,
and at the other end thereof short heads provided with suitable shoulders on their
under sides, between which and the clinched ends of their tapered shanks the
material may be clamped, have for some time been in common use. But as in
order to properly clamp the material, the shoulders on the undersides of the heids
should not pass through the outer lift of said material, the heads are necessarily
made comparatively short, on account of which said heads are the more quickly
worn away than would otherwise be the case, and when this is accomplished it
often occurs that the tapered shank will not hold the remaining lifts and they
become loosened and come off, which difficulty is very desirable to obviate.
To overcome this objection is the object of my present invention, which consists
in a nail having a projecting head the underside of which on different sides of the
nail are at different distances from the pointed end of said nail, all as will be fully
understood from the following description.
In the accompanying drawing, all the figures of which are drawn to an enlarged
scale
Figure 1 represents a front elevation of one of my improved nails.
Figure 2 represents a side elevation of the same.
Figure 3 represents an inverted sectional plan of the saine the cutting plane
being on the line 1, 1 in Figures 1 and 2.
Figure 4 represents an inverted sectional plan of the same the cutting plane
being on the line 2, 2 Figures 1 and 2.
Figures 5 and 6 represent respectively a front and a side elevation of iny
improved nail made from a wire or rod having flat sides.
Figures 7 and 8 represent inverted sectional plans of the same, the cutting
planes being respectively on the lines 3. 3 and 4. 4 Figures 5 and 6 and
Figure 9 represents a section of a number of lifts of a heel with one of my
mproved nails set therein.

page_text: A is a shoe nail made from a round or polygonal wire or rod and having a
head a of a shape in cross section similar to that of the wire from which it is
formed, while, below the head a, a portion of the wire on opposite sides thereof is
cut away to produce a flattened, tapered shank b, the lower ends of which may be
made more or less sharp according to the material into which it is to be driven.
To form two flattened sides of the shank b, portions of the wire are cut away
upon opposite sides thereof to different distances from the pointed end of the nail,
thereby forming at the junctions of said sides, with the under side of the head a,
the shoulders c and c¹ respectively (as shown in figures 2 and 6) at different
distances from the face of the head, which distances may be regulated by the kind
and thickness of material in which the nail is to be driven.
This nail may be made from a round or polygonal wire by milling or by means
of dies or it may be struck up from any suitably shape blanks by dies without
altering the principles of my invention.
The distance between the shoulders c and c¹ is such that one shoulder c will
only enter the outer lift and clamp that against the remaining lifts, while the
second shoulder c¹ will pass entirely through the outer lift and enter the one next
to it and firmly clamp that against the other remaining lifts; and it will continue
to hold said lift even after the outer lift has been entirely worn away, which
would not be the case when those nails were used which had their shoulders c
and cat the same distance from the pointed ends of the nails; as, from the
necessity of the case, the shoulders c and c¹ should not pass through the outer lift
and therefore when that lift and the shoulders c and c¹ were worn away there
would be nothing but the slight taper of the shank to hold the lifts together.
A notch d is cut into the side of the head a, as in consequence of the moisture
and pressure following the wearing of the shoe the leather of the outer lift is
expanded laterally and packed into said notch thus making an additional shoulder
or holding surface.
This notch & may in some cases be dispensed with.
Nails have been cut from a continuous wire having a shoulder or head only
upon one side, the shank being formed by cutting away the surplus inetal all from
one side of the wire, the cut which separates the nail from the wire extending
diagonally from the shoulder across the wire to its periphery, so that the point of
the nail is in line with one side of the wire.
Nails formed in this manner by cutting the stock away all from one side and
the line of the cut extending to the periphery of the wire are objectionable, on
account of the liability of the nails to take a turn outward through the vamp
before this pierce the inner sole.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to
me by my foreign Correspondent I declare that what I claim is :-
First. A nail having a projecting head the under side of which upon different
sides of the nail are at different distances from the ends of the nail.
Second. A nail having a flattened tapered shank and a projecting head, the
under sides of which on opposite sides of said shank are at different distances from
the pointed end of said shank, said head being provided with a notch cut in the
side thereof to serve as an additional shoulder.
