IMPROVEMENTS IN THE MANUFACTURE OF DRUGGET AND DRAWING PINS APPLICABLE ALSO TO OTHER NAILS
Year: 1884

page_text: I, FREDERICK WILLIAM BRAMPTON of the firm of F. Brampton and Company
of No 14 Oliver Street Birmingham in the County of Warwick Manufacturers
do hereby declare the nature of my Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF DRUGGET AND DRAWING PINS APPLICABLE ALSO TO OTHER
NAILS" and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement and accompanying
Sheet of Drawings as follows, that is to say :-
My Invention has for its object improvements in the manufacture of drugget
and drawing pins applicable also to other nails of a compound kind i.e. with a head
made separate to the shank or pin and afterwards fastened thereto which enables
me to fix the heads of such nails far more firmly than has hitherto been the case-
Indeed they may be so firmly fixed that it is almost impossible to remove the head
say of a drugget pin without distroying the pin itself-Such pins usually when
driven with a hammer at once turn on one side and the heads then come off
leaving the shank of the pin in the floor which is most inconvenient and
annoying.
I will explain my Invention by at once referring to the accompanying
Drawings:-Figure 1 and Figure 2 illustrate two kinds of nails in their finished
condition while the remaining Figures illustrate the various separate parts used in
making the nail shown by Figure 1 the parts also of Figure 2 will be thereby
clearly understood also.
A is the shank which is generally made from iron or steel.
B is the disc plate for forming the head which is generally made from brass or
somewhat softer metal than the shank.
C is a metal washer generally made of brass or other soft metal which may be
moulded into shape under pressure.
Figure 3 is an illustration showing the parts A, B and C threaded together and
placed partly in the bottom tool E with top tool D directly over them and ready
to come down. When this top too! D is brought down upon these parts they are
formed into the finished pin shown in side elevation by Figure 1 and in sectional
elevation by Figure 4. The latteral serations & in the shank A are thus thoroughly
filled by the washer or enlargement C being forced against the inclined surface m
Priced

page_text: of the bottom mould Ẹ while the enlarged n of the shank A forms a somewhat
conical or countersunk recess in the upper part of the disc plate B as shown by
the sectional elevation Figure 4. The disc plate B is thus enclosed between what
is practically the two heads of a rivet and it cannot be moved when carefully
.formed as herein set forth. The washer C in some cases may be one piece with
the head A.
The upper and lower surfaces of such heads may be made to almost any device or
ornamentation. The pin shown in Figure 2 is formed by using an ordinary brass
headed nail as the shank the other parts being as explained for the drugget nail
Figure 1 and 4.
It will be evident that this principle of making pin is applicable to other kinds
of nails being of a compound nature i.e. having a shank and kind made from
separate parts.
Having therefore now particularly described and ascertained my said Invention
what I claim is :-
The improvements in the manufacture of pins and nails of the doubly rivetted
head by means of the washer or enlargement C forced into latteral recesses or held
by junction in the shank A substantially as herein set forth and illustrated.
