Improvements in or relating to the Hanging of Doors and Shutters,
whereby the Closing of same may be rendered Automatic
Without the Aid of Springs.
I, AUGUSTINE MCNERNEY, of No. 14 Gordon Street, Dublin, Ireland,
Gentleman, do hereby declare the nature of this invention to be as follows:-
:-
This invention relates to improvements in the method of hanging doors and
shutters, whereby the same may be opened or closed with greater ease and security,
than by the arrangements at present in use.
In carrying out my invention I propose to hang the doors or shutters from
the top and to slide them in suitable grooves, thus dispensing with hinges and
springs.
In the casing over the door or shutter I arrange three grooves parallel to each
In these grooves

pulleys secured to the upper part of the door or shutter travel, so that the same
may be readily moved backwards or forward without difficulty.
The lower portion of the door or shutter slides in a. suitable groove formed in
the floor, whereby oscillation or lateral movement is prevented, and the door or
shutter caused to slide in a true line.
To render the closing movement automatic the three grooves in the upper case-
ment can be adjusted to a slight incline, so that on the door or shutter being
pressed backwards, the hanging pulleys will ascend the inclined grooves, and on
being released the door or shutter by its own weight will return to its normal
position.
By this arrangement springs are dispensed with, and a simple method of auto-
matically closing a door or shutter provided.

COMPLETE SPECIFICATION.
Improvements in or relating to the Hanging of Doors and Shutters,
whereby the Closing of same may be rendered Automatic
Without the Aid of Springs.
I, AUGUSTINE MCNERNEY, of No. 14 Gordon Street, Dublin, Ireland,
Gentleman, 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 improvements in the method of hanging doors and
shutters whereby the same may be opened or closed with greater ease and security
than by the arrangements at present in use.
In carrying out my invention I propose to hang the doors or shutters from
the top, and to slide them in suitable grooves, thus dispensing with hinges and
springs.
In the casement or framing of the door or shutter I arrange grooves parallel to
In
each other, and in the same plane as the direction in which the door moves.
the upper grooves, rollers, secured to the upper part of the door, or shutter travel
on rails, so arranged that the door or shutter may be readily moved backwards or
forwards without difficulty.

page_text: The lower edges of the door or shutter slide in suitable grooves formed in the
floor whereby oscillation or lateral movement is prevented and the door or shutter
caused to slide in a straight line.
To render the closing movement automatic the rails carrying the rollers in the
upper casement can be adjusted to a suitable incline, so that on the door or shutter
being pressed backwards, the hanging rollers will ascend the inclined rails, and
on being released the door or shutter by its own weight will return to its normal
position.
In order that my said invention may be more readily understood, and carried
into practice, I will describe the accompanying drawings:-
Fig. 1, is a front view showing a pair of doors hung according to my invention
in a closed position; and
Fig. 2, illustrates the mechanism for automatically closing the doors, showing the
right hand door fully closed, and the left door partly open.
A, A, are the doors which are hung by means of the rollers b, b, attached by
suitable plates to their upper edges; c, c, are the rails resting their free ends in the
brackets d, the other ends being pivotted to the hanging bracket e, which latter is
suspended from the frame by means of the milled headed screw, whereby the
incline of the rails can be adjusted, and thus the speed with which the doors auto-
matically close increased or diminished at pleasure. The upper rails prevent door
from kicking when opened.
To the bottom edge of the doors metal plates g, shown in dotted lines, are
secured at each side which run in two parallel grooves formed in the floor. These
grooves are wider at the base than at the upper surface, and underneath is arranged
a tray h, inclining towards the centre for the purpose of receiving dust and so
forth, and for the removal of which a small trap door may be formed conveniently
in the floor.
When my invention is applied to an outside door, a pipe or channel may be used
in connection with this tray to carry off any deposit of water. i, i, are handles
attached to the doors to facilitate the movement thereof; k, k, are latches which
catch the handles, and serve to hold the doors full open.
Along the closing edges of the doors, strips of india-rubber may be secured in
order to break the shock of the contact of the doors when being closed, and also
to make the contact air-tight.
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 :-
First. For the purpose of opening and closing doors or shutters, the use and
application of mechanism, arranged and operating in the manner substantially as
herein described and set forth.
Second. For the purpose of opening and closing doors or shutters, the com-
bination formed by the doors A, A, the rollers b, b, the rails c, c, the hanging
and plates g, all arranged and operating in the manner substantially as
herein specified and set forth.
