COMPLETE SPECIFICATION.
Improved Means for Fastening Doors and the like.
I SYDNEY CRICK, of 7 Roche Terrace, Portmadoc, Clerk on Railway, 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:-
This invention relates to improved means for fastening doors and the like, the
object of same being to provide a simple fastening means for preventing the handle
of the door or the like being turned from the outside, whereby the ordinary lock
and other similar insecure fastening means can be dispensed with.
And in order that my invention may be more readily understood, I have shewn
the same upon the accompanying sheet of illustrative drawings, wherein :
Fig. 1 is a front view of part of a door with my invention applied thereto,
Fig. 2 being a side view thereof, while
Figs. 3 and 4 are parts of the invention. shewn separate.
a is a metal or other pin, formed as shewn, with a circular or other suitably
shaped stem or shank, which is inserted through a perforation 6 cut or otherwise
formed through the shank of the bolt c and the lock case d, and part of the door e.
This said key a when inserted into the aforesaid perforation 6, and pushed in a
sufficient distance, as shewn in Fig. 2, prevents the bolt e being drawn back when
the handle is turned.
The beforementioned perforation is not carried completely through the door e
as shewn in Fig. 3, for the purpose of preventing anyone on the outside of the door
from ascertaining the whereabouts of the pin a.
Te prevent the key a being dislodged or pushed out, in case the whereabouts of
same is discovered, I provide a bent spring which would be screwed or otherwise
fastened to the door as shewn at g¹ (Fig. 2).
A portion of the stem or shank of the key a, is recessed or nicked as shewn at a',
so that when the said key is pushed into the perforation b, in the position shewn,
the extremity of the said spring y will press tightly against the shoulder a² formed
on the said stem or shank by recessing or nicking same as before described, and so
prevent the pin a being pushed out of the perforation b.
When it is desired to withdraw the pin a from out of the perforation 6, the said
pin is given a half-turn either to the right or left, thereby bringing the unrecessed
part of the stem or shank of same against the extremity of the aforementioned
spring g, and allowing the pin to be readily withdrawn from the perforation.
The pin a is provided with a head a³ for convenience in turning and withdrawing
the said pin.
A chain or cord may be attached to the eye a³ in the head of the pin, while the
other end can be attached to the door.
By this means the pin will be always ready to hand when required.
My invention can be used on a door in conjunction with a lock or without same,
as desirable or convenient.
I fix the spring g in the perforation b, as shewn in Fig. 2, with the part gl
screwed to the door as shewn, and over this I affix in any suitable manner, a brass
or other metal cap or plate 1, perforated in the centre as shewn, for the stem or
shank of the pin a to go through.
The bolt of the door will be preferably formed as shewn in dotted lines,
instead of tapering off as in the present form of bolts.
The reason I preferably form the shank of the said bolt in this manner, is,
because if the said shank were formed in a tapering form as heretofore, the

page_text: perforation would so weaken same as to render it liable to be snapped when the
door handle was turned.
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 :
:-
The improved means for fastening doors and similar objects, consisting of a pin a,
perforation b, spring g and cap h, operating in manner substantially as described
and shewn, and for the purpose set forth.
