COMPLETE SPECIFICATION.
Improvements in and connected with Ornamental and Brass
Headed Nails.
1, CARL KÜHNEL of Peterswald near Bedenbach in the Kingdom of Bohemia,
Manufacturer, 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:--
Nails with ornamental heads and with plain brass heads as hitherto made and
used in upholstery, by trunk makers, and for various purposes, besides being defective
in other respects have generally been too light and weak, so as to render it difficult
if not impossible to drive the nails without damaging them even in the event of
special instruments being employed.
The object of the present invention is to avoid these defects by producing a
strong head which will withstand the blows necessary to drive the nails without
fear of defacement, bending or other damage. Its object is also to improve the
method of and means for securing the parts of the nail together. I will describe
my improvements with reference to the accompanying drawings.
I first take a circular disc a Figure 2 of thin brass, German silver, nickel, zinc,
iron, or other suitable metal or material and press or otherwise form it to the cup
shape indicated by Figure 3. This may conveniently be done between suitable
dies. The metal or other cup is then passed over the head of the nail under
which it is burnished drawn or pressed to the contracted form indicated by Figure 4.
The ornamental or false head A Figure 1 has in the meanwhile been prepared with
a hole in its centre through which the contracted part d of the hood on the head of
the nail can be passed so that its upper part rests against the part c.
The part d
is then turned up or expanded within the ornamental or false head in such a manner
as to enclose the inner diameter of the hole in the false head, and clip it firmly
below the part c.
This may be accomplished by means of a hammer and hollow
punches or by means of special implements or presses, the result being indicated in
vertical sectional elevation by Figure 5. The complete nail is shewn in elevation
by Figure 6. The nail thus completed may then be scoured polished lacquered
and finished in any desired manner.
It will be understood that the false head may have any desired and suitable
shape and form and that more than one nail may if required be secured in a single
false head.
By fitting and securing the false head upon the nail as hereinbefore described
instead of by the older methods of soldering and brazing, a much neater and
safer job is made, and it is likewise possible to form the heads of such metals
as tin, tinned iron, zinc, and iron, which could not otherwise be conveniently
employed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. As a new article of manufacture, a nail having a false head or ornament
securely fixed thereon substantially as and by the means hereinbefore described
and as illustrated by the accompanying drawings.
2. Securing a false head or ornament upon a nail by means of a hood contracted
upon the head of the nail, the false head or ornament being placed over the con-
tracted part of the hood the lower end of which is then turned up or expanded so

page_text: as to grip the false head or ornament in place, substantially as herein before described
with reference to the accompanying drawings.
