Improvements in the Construction of Banbury or Stock Locks.
I, JOHN LINDSAY, 19, Shand Street, Wishaw, in the County of Lanark, North
Britain, Ironmonger, do hereby declare the nature of this invention to be as
follows:-
My invention of improvements in the construction of Banbury or stock locks
refers to locks with wooden stocks which have the works fixed to the wood, and
relates to the method of fixing the keyway frame, and the spring to the wood.
The first part of my invention I carry out as follows. I take a piece of metal,
long enough to form both lower plate and sides for the frame, and slit it at the
two edges at four different places, in such a way that when the sides are bent up
perpendicular, the four slit parts form four prongs, capable of being driven
into the wood. The prongs can be left long enough to go through the wood, and
be clenched.
The second part of my invention I carry out by bending the flat spring to a
certain shape, and jamming it between the sides of the channel in which the bolt
slides, the end and heel of the spring fitting into a notch on each side of this
bolt channel.
In a modification I simply bend the flat spring to an angle of or about ninty
degrees, and jam it between the sides of the bolt channel, the end of the spring
fitting into a notch on one side, while the flat part bears against the opposite
side.
DESCRIPTION OF DRAWINGS.
Figure 5 is a metal blank long enough to form both lower plate and sides for
the keyway frame. This is slit up on both edges at four places marked a so that
when bent up as in Figure 1, those slit parts form four prongs which are driven
into the wooden stock. Figure 3, A shows the keyway frame fitted into its
place. Figure 2 shows the arrangement for piped keys. Figure 3 shows the
spring B jammed into notches 6 & c on each side of the bolt channel D. Figure 4.
shows a modification of this spring which is simply bent to an angle of or about
ninty degrees, and the end d fits into the notch c (Figure 3) of the bolt channel.
while the top or flat part f bears hard against the opposite side of the channel.

tained in and by the following statement:-
My invention of improvements in the construction of Banbury or stock locks
refers to those locks with wooden stocks which have the works fixed to the wood
and relates to the method of fixing the keyframe, and also the spring to the
wood.
The first part of my invention I carry out as follows. I take a piece of metal
long enough to form both lower plate and sides for the key frame or. bridge
and slit it at the two edges at four different places in such a way that when the
sides are bent up perpendicular the four slit parts form four prongs capable of
being driven into the wood. These prongs can be left long enough to go through
the wood and he clenched. The second part of my invention I carry out by
bending the flat spring to a certain shape and jamming it between the sides of
the channel in which the bolt works, the end and heel of the spring fitting into
a notch on each side of this bolt channel. This spring can be stiffened by
making the bend more acute and still more stiffened by jamming the flat part
of it against the top side of the bolt channel.
In a modification I simply bend a flat spring near its thick end to an angle of
or about 90 degrees and jam it between the sides of the bolt channel, the end
of the spring fitting into a notch on the bottom side while the flat part simply
bears hard against the top side.
DESCRIPTION OF DRAWINGS LEFT WITH PROVISIONAL SPECIFICATION.
Figure 5, is a metal blank long enough to form both lower plate and sides for
the keyframe or bridge. This blank is slit up on both edges at four different
places marked a, so that when bent up as in Figure 1 those slit parts form four
prongs which are driven into the wooden stock.
In Figure 3 the keyframe A is shown fitted into its place in the wooden stock.
Figure 2 shows the arrangement for piped keys.
Figure 3 shows the spring B jammed into notches & c, on each side of the
bolt channel D. This spring can be stiffened by making the bend more acute
such as in Figure 4 and still more stiffened by jamming the flat part hard against
the top side of the bolt channel near Figure 3 Figure 4 shows a modification
of this spring which is simply bent to an angle of or about 90 degrees and the
end fits into the notch (Figure 3) on the bottom side of the bolt channel
while the flat part f bears hard against the top side of the channel near b.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is-
1. The manner of securing the keyframe or bridge to the wooden stock by
forming prongs on it as herein before described.
2. The manner of securing the spring to the wooden stock either by the original
or by the modified plan as herein before described.
