I, FREDERIC ARTHUR HARRISON of Legge Lane, Birmingham in the County of
Warwick, Manufacturer do hereby declare the nature of this invention to be as
follows:--
My invention consists in the manufacture of bolts and nuts so as to produce a clear
and well finished article without much dressing, filing or finishing.
In making improved bolts and nuts according to my invention, I cut out of strong
sheet brass or other metal or alloy, a blank of any suitable form-by preference
circular-and in the centre of the said blank 1 pierce a hole to fit the stem or shank
herein after described. I then take a piece of wire of brass or other metal or alloy,
and screw a short portion of one end and so form the stem or shank of the bolt, the
plain end of the wire is then passed through the piercing in the centre of the blank
herein before described, by means of dies or tools operated in a press or stamp a
smart blow is given to the blank which now forms the head of the bolt, and by one
and the same operation the head is securely fixed to the stem or shank and
desired design or ornament is given to the head of the bolt, it is then ready for the
nut hereinafter described.
any
The wire from which the stem or shank is made may be round, square, hexagon or
any other desired form and may have a head formed on the plain end so as to fix it
more securely in the head of the bolt.
In making the nut, I cut out of strong sheet brass or other metal or alloy, a blank
of suitable size and shape, I then make a piercing in the centre which is then tapped
or screwed to fit the screw on the end of the stem or shank of the bolt herein before
described. The nut may be stamped so as to bevil or chainfer the edges or otherwise
give suitable form or design.

Improvements in the Manufacture of Bolts and Nuts for Affixing
Saw-blades and other Articles to their Handles and other
Purposes.
I, FREDERIO ARTHUR HARRISON of Legge Lane, Birmingham in the County of
Warwick, Manufacturer, do hereby declare the nature of this invention and in what
manner the same is to he performed, to be partieularly described and ascertained-
in and by the following statement:-
My invention consists in the manufacture of bolts and nuts so as to produce a clear
and well finished article without much dressing, filing, or finishing.
In making improved bolts and nuts according to my invention, I cut out of strong
sheet brass or other metal or alloy, a blank of any suitable form-hy preference
circular and in the centre of the said blank 1 pierce a hole to fit the stem or shank
herein after described. I then take a piece of wire of brass or other metal or alloy
and screw a short portion of one end and so form the stem or shank of the bolt, the
wire is then passed through the piercing in the centre of the blank herein before
described by means of dies or tools operated in a press or stamp a smart blow is
given to the blank which now forms the head of the bolt, and by one and the same
operation the head is securely fixed to the stem or shank and any desired design
or ornament is given to the head of the bolt, it is then ready for the nut herein after
described.
The wire from which the stem or shank is made may be round, square, hexagon, or
any other desired form and may have a head formed on the plain or unscrewed end so
as to fix it more securely in the head of the bolt.
In making the nut, I cut out of strong sheet brass or other metal or alloy, a blank
of suitable size and shape, I then make a piercing in the centre which is then tapped
or screwed to fit the screw on the end of the stem or shank of the bolt herein before
described. The nut may be stamped so as to bevil or chamfer the edges or otherwise
give suitable form or design, and by one and the same operation a nick or groove is
forced in the face of the nut for screwing the nut up tightly by means of an ordinary
turnscrew.
The shank or stem of the bolt may be made without screwing and used as a rivet,
and the piercing in the nut may be left without tapping or screwing and used as a
washer for affixing the blades of saws, knives and other articles to their handles.
Figure 1 of the accompanying drawing represents a blank of brass or other metal
or alloy suitable for forining the head of the bolt and provided with a piercing a to
fit the stem or shank.
Figure 2 represents the stem or shank with one end screwed, and a hend b formed
on the other end so as to fix it more securely in the head of the bolt.
Figure 3 represents figure 2 passed through the piercing a in figure 1. A smart
blow is given to the blank, by means of dies or tools operated in a press or stamp,

page_text: which now forms the head of the bolt, and by one and the same operation the head is
securely fixed to the stem or shank and any desired design or ornament is given to
the head of the bolt.
Figure represents the stem or shank with the head fixed on as herein before
described and ready for the nut.
Figuro 5 represents a blank of brass or other metal or alloy, suitable for forming
the nut, with a piercing c for tapping or screwing to fit the screw on the end of the
stem or shank.
Figure 6 represents in cross section the nut stamped so as to bevil or chamfer the
edges.
Figure 7 represents in front elevation the nut with neck or grooved for screwing
up with an ordinary turnscrew.
Figure 8 represents in side elevation and figure 9 represents in cross section a
complete bolt and nut.
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 "Improvements in the manufacture of bolts and nuts for affixing saw-blades
and other articles to their handles, and other purposes."
First Making the head of the bolt from sheet metal and piercing a hole in the
centre to fit the stem or shank, substantially as herein before described and illustrated
in figure 1 of the accompanying drawing.
Secondly Making the stem or shank from wire, passing the same through piercing
in the blank for forming head of bolt and then by means of dies or tools operated in
a press or stamp giving a smart blow to the blank which now forms the head of the
bolt and by one and the same operation the head is securely fixed to the stem or
shank and any desired design or ornament is given to the head of the bolt, sub-
stantially as herein before described and illustrated in figures 2. 3 and 4 of the
accompanying drawing.
Thirdly Making the nut from sheet metal, and by the process of stamping,
bevilling or chamfering the edges or giving other suitable form or design and by one
and the same operation forcing a nick or groove on the face of the nut, substantially
as herein before described and illustrated in figures 5. 6. and 7 of the accompanying
drawing.
Dated this Twenty seventh day of January 1888.
