Improvements in the Construction of Barrel Bolts.
I, WILLIAM SANDERS, Managing Director of the firm of Sanders Son and Payne
Limited, of Leopold Street Birmingham, in the County of Warwick, Brassfounders,
do hereby declare the nature of this invention to be as follows:-
My invention relates to the manner in which I construct and arrange barrel bolts
by means of which I am enabled to make a more simple and efficient attachment of
one portion of the bolt to the other than is at present possible, and I am also enabled
to form a barrel bolt which will hold the sliding bolt more securely than by the system
of construction now in general use.
In carrying my invention into effect I construct a barrel bolt having its main
portion in the form of a circular tube with a projection or recess formed along its
bottom or underside. 1 by preference draw the metal tube of the desired shape that
is, with the circular part having the projection formed upon its entire length, and by
reason of the tube being thus drawn or formed in great lengths I am enabled to cut
off any desired length and thus to make a barrel to suit any particular requirement, zo
far as the length of the bolt is concerned. Instead of drawing the tube through plates
by the ordinary methods of mill work I sometimes make the tube in dies, or with
tools, from a strip or plato of metal by any ordinary and usual pressing tools or
appliances.
The projection, recess or channel which runs along the entire length of the 'tube I
pierce with holes at suitable intervals for the purpose of receiving lips or ears
standing up from or out of a metal flange or back plate which I attach to the tube or
barrel.
This metal flange or back plate I form out of any kind of metal and I make it the
length required to suit the particular barrel, and of a width that will admit of screws
passing through, to attach it to any door or other object.
The central part of this flange or back-plate I pierce so that lips, flaps or ears stand
up from the surface of the metal of a width which will enable them to enter the
grooves, slots or openings formed in the channel or recess of the barrel,-that is to say,
pierce and form as many pieces of projecting lips or ears as there are grooves or
openings formed in the barrel; and I slip these lips into the grooves, and then by
sliding the plate along cause the lips to rost upon the solid portion of the recess or
channel and thus to be held by it.
I further secure the flange to the tube by pressing down the lips or cars so that they
become bedded on to the bottom of the groove or channel and when in this position
there is no projection within the barrel to prevent the free sliding of the bolt within
the interior of the barrel tube. Sometimes 1 allow one or more of these lips to remain
free and not to be firmly pressed into the groove or channel for the purpose of acting
as a spring against the bolt within the barrel and thereby to prevent its falling down;
or 1 rivet a spring or springs to the plate which enters the channel and in the same
manner prevents the bolt from slipping away.
The bolt when it is within the barrel assists the connection of the flange plate to the
barrel tube seeing that it prevents the movement of the one from the other by reason
of its filling up the whole of the space of the tube.

Improvements in the Construction of Barrel Bolts.
I, WILLIAM SANDERS Managing director of the firm of Sanders Son and Payne
Limited, of Leopold Street, Birmingham, in the County of Warwick, Brassfounders,
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 relates to the manner in which I construct and arrange barrel bolts, by
means of which I am enabled to make a more simple and efficient attachment of one
portion of the bolt to the other than is at present possible, and I am also enabled to
form a barrel bolt which will hold the sliding bolt more securely than by the system
of construction now in general use.
In carrying my invention into effect I construct a barrel bolt having its main
portion in the form of a circular tube with a projection or recess formed along its
bottom or underside. I by preference draw the metal tube of the desired shape, that
is, with the circular part having the projection formed upon its entire length, and by
reason of the tube being thus drawn or formed in great lengths, I am enabled to cut
off any desired length and thus to make a barrel to suit any particular requirement
so far as the length of the bolt is concerned. Instead of drawing the tube through
plates by the ordinary methods of mill work, I sometimes make the tube in dies, or
with tools, from a strip or plate of metal by any ordinary and usual pressing tools or
appliances.
The projection, recess or channel which runs along the entire length of the tube I
pierce with holes at suitable intervals, for the purpose of receiving lips or cars standing
up from, or out of a metal flange or back plate which I attach to the tube or barrel.
This metal flange or back plate I form out of any kind of metal, and I make it the
length required to suit the particular barrel, and of a width that will admit of screws
passing through, to attach it to any door or other object.
The central part of this flange or back plate 1 pierce so that lips, flaps, or ears
stand up from the surface of the metal of a width which will enable them to enter the
grooves, slots or openings formed in the channel or recess of the barrel, that is to say
I pierce and form as many pieces of projecting lips or ears as there are grooves or
openings formed in the barrel; and I slip these lips into the grooves, and then by
sliding the plate along cause the lips to rest upon the solid portion of the recess or
channel and thus to be held by it.
I further secure the flange to the tube by pressing down the lips or ears so that they
become bedded on to the bottom of the groove or channel, and when in this position
there is no projection within the barrel to prevent the free sliding of the bolt within
the interior of the barrel tube. Sometimes I allow one or more of these lips to remain
free and not to be firmly pressed into the groove or channel, for the purpose of acting
as a spring against the bolt within the barrel, and thereby to prevent its falling down;
or 1 rivet a spring or springs to the plate which enters the channel and in the same
manner prevent the bolt from slipping away.
The bolt when it is within the barrel assists the connection of the flange plate
to the barrel tube, seeing that it prevents the movement of the one from the other, by
reason of its filling up the whole of the space of the tube.
In order that my invention and the manner of performing the same may be properly
understood and readily carried into effect I append hereunto one sheet of explanatory
drawings to be hereinafter referred to.
Fig. 1 is a plan of the metal flange or back of my improved barrel bolt showing the
peculiar manner in which I pierce the plate for forming the attachment to the barrel ;
and Fig. 2 is an end elevation of the same. The metal plate A I pierce or cut in any
ordinary manner to form channels B. B with central ears or lips standing free from
0
side connection or support. These lips or ears C I bend or press down beneath the

page_text: surface to the depth as shown in Figs. 3 and 4; so that between the projecting ears C¹¹
and the metal plate A a space D exists for receiving a thickness of metal between.
The barrel I draw or form in any usual or ordinary manner, so that it has the
peculiar shape E, F shown in Fig. 5 and Fig. 6. The lower portion F of the
barrel I cut away at intervals as shown in Fig. 7 and Fig. 8 to suit the recesses formed
within the plate A; and within the recesses and spaces D D I thread or interlace one
portion to the other, causing the ears to enter the openings G G. and then to slide
forward and rest upon the metal surface H of the tube or barrel E. When the one
portion A is thus threaded into the other portion E as shown in Fig. 9 and Fig. 10,
press down the projecting ears ( so that they form a flat surface or support for the
lower portion of the bolt N ; and I press the metal around the recesses and ears so
that complete contact is obtained and the openings G are covered by the whole
portions of the plate A, while the projections H fill up the cut away or recessed
portions B of the plate A.
"
I close the end of the tube E with a metal disc M. and I pierce the barrel at L L¹
for allowing the knob lever K to fit into when at its "in" or out" position; and
I also pierce the barrel at L³ to allow of the movement of the knob K' from L to L.
The bolt NI construct in any usual or ordinary manner and I employ any suitable
metal for the construction of my improved barrel and flange in the manner herein-
before described.
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. The construction of barrel bolts having flanges formed out of metal plate pierced
to thread on to the barrel by means of projections formed upon the plate or flange,
as and for the purpose hereinbefore described and substantially as illustrated in the
accompanying drawings.
2. The construction of a barrel such as E, for forming a barrel bolt, having serrations
such as G within the base substantially as and for the purposes set forth.
3. The construction of a flange or back plate of a barrel bolt such as A, having
recesses and ears such as B, C formed therein substantially as and for the purposes
set forth and as illustrated in the accompanying drawings.
