Improvements in Nails.
I, DANIEL ASCOLI, of 18, Huntingdon Terrace, Green Lanes, London, N., Boot
Dealer, 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:-
-
My invention relates to improvements in all kinds of nails, and has for its
object to increase the grip or bite between such nail and the leather, wood or
other resilient substance or substances into which it is to be driven in order to
prevent its spontaneous removal therefrom by reason of the drying or shrinking
of such substance or substances, as obtains with the ordinary nails of commerce
when driven into wet leather or green wood, and such leather or wood becomes
dry and the grain thereof opened.
As an example of some of the many types of nails to which the principle of
my invention may be applied, I have hereunto appended a sheet of drawings of
which
Fig. 1 is a much enlarged side elevational view of a hob-nail according to my
invention, as chiefly used in the making of a certain class of boots and shoes.
Fig. 2 is a like view of an ordinary cut or clout-nail, Fig. 3 being a like view
of an ordinary coffin or upholsterers-nail.
Fig. 4 is a sectional illustration of a hob-nail, such as Fig. 1, and its applica-
tion in connection with the binding together of two or more layers or thickness
of material.
My invention consists essentially of forming upon the hitherto tapered stem
of a nail (during the casting or other means of producing same) an annular or
partly annular protuberance or swelling the upper and lower portions of which
said protuberance or swelling I prefer shall taper gradually from the upper or
thickest end of the stem, and gradually fade away into and become the point of
the nail, and further that for preference the cross sectional formation of such
protuberance shall harmonize with that of the sectional formation of the upper
end of the said stem, that is to say, if the upper end of the shank A of the nail
be rectangular or circular in cross section, I prefer that the protuberance B
shall be of the same formation, but I do not make this an indispensible condition.
In the manufacture of hob-nails as illustrated by Fig. 1. and used in the
manufacture of boots and shoes, I prefer that the said protuberance B shall be
in such a position upon the stem A as to pass through the uppermost laver of
leather (such as the top piece of a heel, or the clump of a sole, as suggested by C,
and pass into and be imbedded in the second layer of the heel or the sole of the
boot as suggested by D in Fig. 4. so that when C becomes dry or shrunk, and
its grain more open, the said nail would be prevented from spontaneous with-
drawal by reason of its firm connection with the next layer D. The same
principle would apply in connection with clout or wood nails such as shewn in
Fig. 2. the said protuberance B being in such a position as to become imbedded
in the innermost portion of a second or lower piece of timber to which the outer-
most or upper piece is to be connected,

page_text: In all nails having a solid head EI form upon the under surface of such head
any number of depending spikes such as F (Figs. 12 and 4) which engage with
the substance of the upper layer or material C as in Fig. 4, and so prevent the
turning of the nail and enhancing its connection with the said piece C, but in
case of coffin or upholsterers nails having hollow heads E as in Fig. 3, the said
spikes may be found superfluous and may be omitted.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
In the manufacture of all kinds of nails the use and application of spikes such
as F, upon the under surface of the solid head E, and a protuberance such as B
upon the stem A of such nails, substantially as and for the purposes herein
described and shewn.
