We JOHN CARDWELL, Broker and JAMES CHANDLER, Engineer both of
82, Doncaster Street, Liverpool do hereby declare the nature of our invention to
be as follows:-
The object of this invention is to construct a bolt which shall not require to be
screwed into position but simply pushed in and will fasten itself.
In carrying out our invention we taper the end of the bolt and form an annular
groove around the same-As applied to shutter bars this bolt so constructed as
aforesaid is arranged to be pushed through the shutter bar and shutter into a
suitable box or recess secured at the back of the shutter and in which is a sliding
spring catch. This spring catch is raised by the insertion of the tapered end of the
bolt and springs back again into the annular groove and so secures the bolt in
position. To withdraw the bolt it is necessary to raise the spring catch and this
can only be done from the inside of the shop say by means of a suitable handle
or from a distance by a cord or in any other convenient manner.
It will be obvious that this improved fastening equally applicable to securing
window sash bars and for other analogous purposes.

Sliding Sashes, and for other Analogous Purposes.
We JOHN CARDWELL, Broker and JAMES CHANDLER, Engineer both of 82 Doncaster
Street, Liverpool do hereby declare the nature of our said invention and in what manner
the same is to be performed to be particularly described and ascertained in and by
the following statement :-
The object of this invention is to construct a bolt which shall not require to be
screwed into position but which being simply pushed in will fasten itself.
On the accompanying drawing we illustrate our improved shutter-bar bolting
apparatus in one of its practical applications.
Fig. 1 represents a side view and Fig. 2 a front view of a piece of a sash bar
having an improved bolt fastening applied thereto and Fig. 3 is a sectional view of
Fig. 1. Fig. 4 represents a separate view of the bolt and Fig. 5 a separate view of
the spring catch box with its front plate removed shewing the bolt in section and the
spring catch in its normal position.
In all the views a is the sash bar and 6 the improved bolt passing through the same
and with its point secured in the spring catch box c screwed upon the inside of the
sash bar.
This holt is tapered at the point as illustrated and is provided with an annular
grooved to receive the extremity of the sliding spring catch e mounted in the box c.
This catch e is furnished with a pair of spiral springs which serve to keep it
constantly pressed forwards.
It will however be apparent that upon the insertion of the taper end of the bolt in
the box c the said catch e will become raised or forced back by the passing of the
tapered end of the bolt until its annular groove presents itself opposite to such catch
and so permits the same to fly back into its original position.
In this manner the bolt becomes securely locked and can only be withdrawn from
the inside. To withdraw the bolt it is necessary to raise the spring catch and this can
only be done from the inside of the premises (say of the shop window) by means of a
suitable handle or from a distance by a cord affixed to the upper projecting extremity
of the spring catch e.
It will be obvious that this improved fastening is equally applicable to securing shop
window bars, window sash bars and for other analogous purposes.
We are aware that a patent No. 1168087 has been granted to Edward Jones and we
do not claim anything described and claimed therein.

page_text: Having thus particularly described and ascertained the nature of this our said
invention and in what manner the same is to be performed we declare that what we
claim is :-
The combination of a bolt having an annular groove with a sliding spring catch
mounted in a box substantially as and for the purposes hereinbefore described and
illustrated on the accompanying drawing.
