page_text: 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 manufacturing the barrel and back plate of the said
bolts from strong sheet metal in the manner hereinafter described and also in
connecting the separate barrel to the back plate in the manner hereinafter
described.
In making the barrel of the bolt I cut out by a stamp and cutting tools from.
sheet brass or other ductile metal or alloy a rectangular blank of the length of the
barrel to be made and of a width about double that which the finished barrel is
intended to have. Near one end of the blank a piercing having the shape of the
letter H is made and on the longer edges of the blank two or more pairs of ears
or small projecting pieces are left. By the action of shaping dies worked in a
stamp the flat blank is fashioned into a barrel having a trough form in cross section.
and at the same time and by the action of the same dies one end of the trough
shaped barrel is closed the closed end terminating in a lip of the breadth of the
barrel. The barrel thus made has near the closed end the necessary slots (made
from the H shaped piercing in the blank) for the stem of the bolt handle to work
in and also on its edges two or more pairs of parallel ears or projecting pieces for
connecting the barrel to the back plate.
In making the back plate I cut it from sheet brass or other ductile metal or
alloy and in it I make two or more pairs of piercings equal in number and at the
same distances apart as the pairs of ears or projecting pieces on the edges of the
barrel. That end of the back plate which is to be fixed at the open end of
the barrel is furnished at its middle with a double horn shaped projection for the
purpose hereinafter explained. Countersunk holes for the fixing screws having
been made in the back plate and the horn shaped piece raised at right angles
to the back plate the said plate is ready to be fixed to the barrel. This is effected
by placing the ears or projecting pieces at the edges of the barrel through
the piercings in the back plate and rivetting or expanding the projecting ends of,

page_text: the said ears on the inner face of the said back plate. The barrel and back plate
are thereby fixed together the horn shaped piece on the end of the back plate
projecting into the open end of the barrel and constituting a curved seat for the
sliding rod or shoot of the bolt to seat itself upon.
The barrel bolt is completed in the ordinary way by combining with the barrel
the sliding rod or shoot,
Instead of attaching the back plate to the barrel by rivetting as described they
may be connected together by soldering.

and other Articles.
I FREDERIC 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 be performed, to be particularly described and ascertained
in and by the following statement:-
My invention consists in manufacturing the barrel and back plate of the said
bolts from strong sheet metal in the manner herein after described and also in
connecting the separate barrel to the back plate in the manner herein after
described.
In making the barrel of the bolt I cut out by a stamp and cutting tools from
sheet brass or other ductile metal or alloy a rectangular blank of the length of the
barrel to be made and of a width about double that which the finished barrel is
intended to have. Near one end of the blank a piercing having the shape of the
letter H is made and on the longer edges of the blank two or more pairs of ears or
small projecting pieces are left. By the action of shaping dies worked in a stamp
the flat blank is fashioned into a barrel having a trough form in cross section and
at the same time and by the action of the same dies one end of the trough shaped
barrel is closed the closed end terminating in a lip of the breadth of the barrel.
The barrel thus made has néár the closed end the necessary slots (made from the
H shaped piercing in the blank) for the stem of the bolt handle to work in and
also on its edges two or more pairs of parallel ears or projecting pieces for connecting
the barrel to the back plate.
In making the back plate I cut it from sheet brass or other metal or alloy
and in it I make two or more pairs of piercings equal in number and at the same

page_text: distances apart as the pairs of ears or projecting pieces of the barrel. That end of
the back plate which is to be fixed at the open end of the barrel is furnished at its
middle with a double horn shaped projection for the purpose herein after explained.
Countersunk holes for the fixing screws having been made in the back plate and
the horn shaped piece raised at right angle to the back plate the said plate is ready
to be fixed to the barrel. This is effected by placing the ears or projecting pieces
at the edges of the barrel through the piercings in the back plate and rivetting or
expanding the projecting ends of the said ears on the inner face of the said back
plate. The barrel and back plate are thereby fixed together the horn shaped piece
on the end of the back plate projecting into the open end of the barrel and
constituting a curved seat for the sliding rod or shoot of the bolt to seat
itself upon.
Or the back plate may be made without the double horn shaped projecting piece
and a separate double horn shaped piece cut out of sheet brass or other metal or
alloy and rivetted or soldered in a piercing provided in the back plate near one end
so that a cranked or bent sliding rod or shoot may be used.
The barrel bolt is completed in the ordinary way by combining with the barrel
the sliding rod or shoot.
Instead of attaching the back plate to the barrel by rivetting as described it
may be connected together by soldering.
Figure 1: of the accompanying drawings represents the blank of brass or other
metal or alloy for forming the barrel of the bolt the said blank having ears or
projecting pieces a for affixing back plate herein after described and also being
provided with a piercing near one end of the shape of the letter H. b is the
H shaped piercing.
Figure 2 represents in front elevation and Figure 3 represents in side elevation
the blank fashioned into a barrel by the action of shaping dies worked in a stamp,
by the action of the same dies one end of the barrel is closed the other end termi-
nating in a lip the breadth of the barrel, the ears or projecting pieces a are for
connecting the barrel to the back plate herein after described, the slots b (made
from the H shaped piercing in the blank) are for the stem of the bolt handle to
work in; c is the closed end of the barrel.
Figure 4 represents the back plate cut out of sheet brass or other metal or alloy
provided with piercings d equal in number and same distance apart as the ears or
projecting pieces a on the edges of the barrel as represented in side elevation
Figure 3. that end of the back plate which is to be fixed at the open end of the
barrel is furnished at its middle with a double horn shaped projecting piece g raised
at right angle to the back plate.
Figure 5 represents a longitudinal section of back plate and the double-horn
shaped projection g raised at right angle: a spring f bearing against the sliding
rod or shoot holds it firmly in its shot or withdrawn position.
Figure 6 represents the back plate affixed to the barrel, this is effected by placing
the ears or projecting pieces a at the edges of the barrel through the piercings d in
the back plate and rivetting or expanding the projecting ends on the inner face
of the said back plate the horn shaped projection g on the end of the back plate
projecting into the open end of the barrel and constituting a curved seat for the
sliding rod or shoot of the bolt to seat itself upon. Instead of attaching the back
plate to the barrel by rivetting as described it may be connected by soldering.
The sliding rod or shoot Figure 7 is combined with the barrel in the ordinary
way by inserting the rod into the barrel through the open end and screwing the
knob or handle into the rod through the H shaped piercing b.
Or the back plate may be made without the horn shaped projection as Figure 8
and be provided with a piercing h in which a separate double horn shaped piece
Figure 9 is rivetted or soldered and a cranked or bent sliding rod or shoot Figure 10
is combined with the barrel as herein before described.
Figure 11 represents a front elevation of a complete bolt with a cranked or
bent sliding rod or shoot,
