PROVISIONAL SPECIFICATION.
Improvements in Nails or Tacks.
We, THOMAS GRAY PARKINSON, Secretary, Westminster Fire Office, JOSEPH
CHARLES GRINSELL, Silversmith and PERCY GIBBS, Insurance Agent, all of
35 Colmore Row, Birmingham, in the County of Warwick, do hereby declare the
nature of our said invention to be as follows:-
Our invention relates to improvements in nails or tacks, of that class chiefly
employed for upholstering, or cabinet work, and, for boxes or receptacles, where a
separation of parts is required, also to the laying or fixing of carpets, so that a
removal may be effected without injury thereto.
The aim and object of our invention is the facility in which a nail or tack can be
driven for purposes in upholstery without injury to the parts forming the shank or
head, hitherto these nails have been constructed in two parts, the head, and the
shank, or spike, the latter being soldered to the former, the heating process of
which softens the spike and when being driven to its purpose constantly doubles
up and is useless.
We will describe our invention thus:
A nail or tack for upholstering purposes, we construct in two parts, the nail
proper, we employ is manufactured by the usual process, but with a ball head, or
head of any other suitable shape. We employ a form of a required configuration in
outline, produced from sheet metal by preference, with tools specially provided, this
may be flat, and plain or ornamented with an embossed surface, the centre being
provided with a small hole, through which is passed the shank or spike of the nail
and the nail is then driven by a blow or blows upon the ball or other shaped head
of the nail. The position of the head of the nail when driven in, forms a neck or
intervening space with the metal form which may now be termed au .ornamental
head. A space thus formed will admit of the introduction of a suitable tool as a
lever and with pressure the nail can be withdrawn without injury to the nail or
article.
A nail or tack when employed for cabinet work, or boxes would be constructed
as above set forth, but the metal form would be plain, and somewhat stronger, when
driven flush, an extra blow will dish or up turn edges of the metal form, so that
the tool above described may be either placed between the head of the nail and
metal form or under the latter, and thus drawn out with facility.
In some cases we may find it necessary to connect the two parts that is the nail
and the metal form to effect this we screw the nail near to the head externally,
and the hole in the metal form, so that it can be fed thereon.

COMPLETE SPECIFICATION.
Improvements in Nails or Tacks.
We, THOMAS GRAY PARKINSON, Secretary, Westminster Fire Office, JOSEPH
CHARLES GRINSELL, Silversmith, and PERCY GIBBS, Insurance Agent, all of
35 Colmore Row, Birmingham in the County of Warwick, do hereby declare
the nature of our said invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
Our invention for "Improvements in nails or tacks" employed for such purposes
as nails or tacks may be used, as upholstery, cabinet, and ordinary woodwork, and

page_text: where such parts may require to be separated, (effected by the removal of the nail,
or tack,) and without injury to the parts where the nail or tack has been driven.
Our invention consists substantially of two parts,
1st. The nail proper, with a head of any shape or configuration, produced in
metal, by the process by which nails or tacks are made.
2nd. The employment of a disc or collar either plain or ornamented, produced
with tools specially provided, and having a small hole pierced in its centre, to admit
of its being placed upon the nail, or tack, and then secured in any suitable way.
And in order that this our said invention may be more clearly understood, we
shall now proceed more particularly to describe the same, and for that purpose we
shall refer to the several figures, on the sheet of drawings, hereunto annexed, the
same letters of reference indicating like or corresponding parts, throughout all the
figures.
Fig. 1, is a view in elevation of a nail constructed according to our invention,
with a circular form having a hole in its centre, through which is passed the shank
of the nail, and partly driven into the wood.
Fig. 2, is a view of same, shewing the form, by extra force driven into the wood,
and the head of the nail flush with the wood.
Fig. 3, is a view in elevation of a nail, constructed according to our invention,
with a disc upon the shank, and driven into the wood, the force of which dishes the
disc, or turns up the edges.
Figs. 4, 5, 6, are views in elevation of nails or tacks constructed according to
the Patent No. 17002, of 1892, Thomas Gray Parkinson, for "Improvements in or
relating to nails or tacks," consisting substantially of a nail, or tack, having two
heads, thus forming an intervening space or neck between, to which we employ
or arrange the collar or disc.
Fig. 7, is a view in plan of the disc or collar in application as Figs. 1 and 2.
Fig. 8, is a view in plan of the disc, in application Fig. 3.
Fig. 9, is a view in plan of the disc having an ornamental surface and Fig. 10
the same with plain surface each having a hole sufficient to pass over the heads c,
of nails as Figs. 4, 5, 6 as indicated by dotted lines.
a, are the stems or spikes of nails, or tacks, as usually constructed, b, shews the
ordinary head, and c, the additional head, the space intervening between, forming
the neck d. e is the collar, f the disc.
e,
In Figs. 1, 2, e, is the circular collar in application, and Fig. 3 in application.
When is arranged upon a, as Figs. 1, 2, and f, upon a, as Fig. 3, both against
the under surface of b, we fix the same permanently by compressing or jagging a,
by a tool, or machine, which causes a swell at or adjacent to e, or f, (or by other
suitable means).
In Figs. 4, 5, 6, we arrange the disc f, over the head c, and bearing upon the
head 6, the mode we employ here for fixing, is to cause a swell, by one or more
blows from a tool, or machine, upon the upper head c.
It will now be observed that our invention consists substantially of the employment
of a nail, with one head, and the application thereto of a collar e, or a disc f, or
the employment of a nail, with an additional head, thereto, and the application of
the disc f, and driven to its purpose by blows direct upon the heads b, or c, and
that when desirous of extracting the nail, and separating the parts nailed together,
a tool or lever can be employed under the head b, as Figs. 1 2 or a tool or lever can
be employed under the head, c, as Figs. 4, 5, 6.
The above being our invention we wish it to be understood in conclusion that we
do not limit ourselves to the precise details, as we may vary or alter the same
without departing essentially from the principle of our said invention.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1st. In "Improvements in nails or tacks," the combination, with an ordinary nail

page_text: and head, with a collar as e, Figs. 1, 2, or a disc as f, Fig. 3, substantially as and
for the purposes above described.
2nd. The combination, with a nail having an additional head, with a disc as f,
Figs. 4, 5, 6, substantially as and for the purposes above described.
3rd. The general combination, and arrangement of parts, substantially as
herein before described, and for the purposes set forth in the foregoing Specification,
and shewn on the accompanying sheet of drawings.
