ROBERT HIRST Gasfitter & Bellhanger 4 Calverly Street Mile End Road London E.
do hereby declare the nature of this invention to be as follows
--
This automatic attachment for connecting a counter flap with the door in the
counter front consists of a rod of brass iron or other metal with a binged joint at one
end to fix to the top of the door. The other end is in the form of an eye to work in
an eye fixed to the underside of flap. When the flap is lifted the door opens to the
full extent and when the flap is shut down the door closes and cannot be opened
until the flap is lifted thus doing away with any bolts or other fastening on the
door.

COMPLETE SPECIFICATION.
Improvements in Means for Connecting Counter Flaps with Doors

Simultaneously.
I, ROBERT HIRST Gasfitter & Bellbanger 4 Calverly Street, Mile End, London,
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 automatic"
attachment for connecting a counter flap with a door in the
counter, front consists of a rod of brass iron or other metal having a stop hinged joint
and provided with an attachment for connecting with electric or other bells for the
purpose of giving an alarm when the flap & door are opened. One end of this metal
rod is fixed to the top of the door and the other end which is in the form of an eye
works in an eye carried by a plate and which is fixed to the underside of the flap.
When the flap is lifted the door opens to the full extent and when the flap is shut
down the door closes and cannot be opened until the flap is lifted, thus doing away
with any bolts or other fastenings on the door.
In order that my said invention may be fully understood and readily carried into
effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a vertical cross section of a counter flap and counter door, shewing my
attachment applied thereto. In this figure the flap is shewn lowered and the door
closed.
Fig. 2 is a similar figure shewing the flap raised and the door opened.
Figs. 3 and 4 are respectively a plan and front elevation of the attachment drawn
to a larger scale.
A is the counter flap and B is the counter door. (is the attachment, which, as is
shewn at Figs. 3 and 4 consists of a metal rod c carrying at one extremity the stop
hinged joint d. At the other extremity it is bent into the form of an eye e which
engages with an eye carried by the plate . These two eyes are preferably coupled
together, before the eye e is completely formed, so that when said eye e is completed,
they may not become detached.
The stop hinged joint d is furnished with a hollow socket d' formed with a screw
[Price di

page_text: thread therein, which is screwed onto the corresponding screw thread formed on the
rod c.
g is the attachment for connecting with the electric or other bells; it is shewn
in the drawings as consisting of a ring or eye, screwing into the socket d¹, but any
other form of attachment, suitable for the purpose; may be employed.
In applying the attachment, the lower joint dx (Fig. 4) of the hinge is secured to
the top of the door, (which is shewn cut away for this purpose in Figs. 1 and 2) and
the eye engaging with the eye e, is attached to the underside of the flap in such.
manner that when the flap is lowered the door will close and the attachment Cwill
lie in a horizontal position (see Fig. 1) and when the flap is raised the door will open,
and said attachment will assume a vertical position (see Fig. 2): The oye on the
rode and the eye attached to the flap forming a kind of universal joint, which permits
of this movement.
1°
Now when the flap is lowered and the door so closed, it will be firmly retained in,
such closed position, by means of the rod or attachment having assumed its horizontal
position, and thus any pressure tending to push open the door, before the flap is lifted,,
is effectually resisted, whereby bolts or other similar fastening devices are rendered
unnecessary.
Having now particularly described and ascertained the nature of my said Inven
tion and in what manner the same is to be performed declare that what I
claim is :-
1. The means for connecting counter flaps with counter doors, consisting of a
hinged attachment, one extremity of which is secured to the door, and the other
extremity to the flap, in such manner that when the flap is raised the door is caused
to open by reason of the attachment assuming a vertical position, and when the flap
is lowered the door is caused to close and be retained and fastened by reason of the
attachment assuming a horizontal position, whereby bolts or other similar fastening
devices are rendered unnecessary substantially as described and shewn by Figs. 1
and 2 of the annexed drawings.
2. In combination with a counter flap and a counter door, the hinged attachinent,
provided with a stop hinged joint d at one extremity and with an eyee at the opposite
extremity, said eye e engaging with and working in an eye f carried by the
counter flap, substantially as described and shewn by Figs. 3 and 4 of the annexed
drawings.
