Improvements in Doors and Connections for Cold Stores and
the like.
I WILLIAM TAYLOR of 73 Koble Road, Bootle, in the County of Lancaster,
Engineer, do hereby declare the nature of this invention to be as follows:-
The invention relates to doors for cold stores and the like where it is necessary that
the circulation of air past such doors should be prevented. Hitherto large sized
doors in spite of packing, taper-fitting, sorew-handles, and other devices have not
been made tight, or if tight fitting have been very difficult to open, or have soon
become slack and allowed air to pass, thus causing considerable extra expouse in
maintaining the interior of the store at the required temperature.
Now the object of my invention is to so construct, fit, and arrange the door and
its counections in a simple efficient and durable manner, that when closed and
tightened, the door and frame shall fit together evenly and closely all round, and the
passage of air or gases to and from the store shall be at all times fully prevented,
whilst the opening of the said door shall be readily and easily effected..
My invention consists essentially in constructing the door with taper edges designed
to closely fit within a corresponding frame or way. On one side, the door is carried
by means of hinges, whilst on the other side it is fitted with securing bars, the said
hinges and bars being provided with means both for tightening and for loosening
the door.
The hinges and bars are so disposed that when tightened; the closing pressure
passes through the centre of the aid door and causes it to bear evenly all round on
the frame or way.
The hinges are each made with a strap fitting over a gudgeon' carried by a cap?
The said cap is free to slide over a stnd secured to the door frame, whilst to and fro
motion is given to the cap and gudgeon by means of a set screw and nut taking into
the stud. The cap and gudgeon are prevented from turning, by, making the stud
square, hexagonal, or of other suitable shape, or keys or like devices may be used..
The securing bars each turn on a pivot so as to be out of the way when not in use,
and are each tightened by a set nut on a hinged stud. The said set nut is made
with a collar which fits between a jaw on the fastening bar.
As will be understood many equivalent mechanical devices may be used for the
various parts without departing from my invention.

Improvements in Doors and Connections for Cold Stores and
the like.
I WILLIAM TAYLOR of 78 Keble Road, Bootle, in the County of Lancaster,
Engineer, 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 :-
The invention relates to doors for cold stores and the like where it is necessary that
the circulation of air past such doors should be prevented. Hitherto large sized
doors in spite of packing, taper fitting screw handles and other devices linve not
been made tight, or if tight fitting have been very difficult to open or have soon
become slack and allowed air to pass thus causing considerable extra expense in
maintaining the interior of the store at the required temperature.
Now the object of my invention is to so construct fit and arrange the door and
its connections in a simple efficient and durable manner that when closed and
tightened the door and frame shall fit together eveuly and closely all round and the
passage of air or gases to and from the store shall be at all times fully prevented,
whilst the opening of the said door shall be readily and easily effected.
My invention cousists essentially in constructing the door with taper edges designed
to closely fit within a corresponding frame or way. On one side the door is carried
by means of hinges, whilst on the other side it is fitted with securing bars the said
hinges and bars being provided with means both for tightening and for loosening
the door.
The hinges and bars are so disposed that when tightened the closing pressure
passes through the centre of the said door and causes it to bear evenly all round on
the frame or way.
The hinges are each made with a strap fitting over a gudgeon carried by a cap.
The said cap is free to slide over a stud secured to the door frame whilst to and fro
motion is given to the cap and gudgeon by means of a set screw and nut taking into
the stud. The cap and gudgeon are prevented from turning by making the stud
square, hexagonal or of other suitable shape or keys or like devices may be used.
The securing bars each turn on a pivot so as to be out of the way when not in use
and are each tightened by a set nut on a hinged stud. The said nut is made with
a collar which fits between a jaw on the fastening bar.
As will be. understood many equivalent mechanical devices may be used for the
various parts without departing from my invention.
DESORIPTION OF THE DRAWINGS.
Fig. 1. is a front view, and Fig. 2. is a horizontal section on an enlarged scale of a
door constructed under ny invention. a. is the door formed with taper edges b. so
as to fit closely against the taper odges c of the frame or doorway. The edges of
the door and doorway may if desired be square or rabetted, instead of taper. The
door is provided with hinges d. at one side. The hinges d. fit over gudgeons or
pins e. carried by blocks or caps f.; the blocks f. are free to slide on studs g secured
to the frame c by bolts h.; the blocks f. can be moved to and fro on the studs g. by
means of set screws i.; the studs g. are preferably formed square to prevent the
blocks. turning thereon. j. are securing bars secured to the other side of the door
by bolts k. which form pivots, and studs over which the inner ends of the bars k.
fit; jaws on the outer ends of the bars & fit round nuts m. on screwed studs n
binged to the frame dat n'. The nuts m are provided with collars m' which act
against the bars k. when opening the door. The bars k. and the studs n with their

page_text: nuts m can be swung on their pivots as shewn at o. so as not to offer any obstruction
when the door is open. p. is a roller for supporting the door when open in the usual
manner. The binges d. are preferably formed as part of, or secured to, bars d' which
extend across the door, and the bars k preferably bear upon the other ends of the
bars d' so that the closing pressure exerted by the nuts m. on the bars k. and by
the set screws i. upon the hinges d. is directed by the bars d. towards the centre of the
door a. thus ensuring that the edges of the door bear evenly against the edges of
the doorway all round.
The operation of securing tho door is as follows:-The door is closed, the bars k.
are swung into position as at q. and the studs n, are swung so that the nuts m. enter
within the jaws of the bars k. The nuts m. and set screws i. are then turned so as
to traverse the bars k. and hinges d. in the direction of the arrows and so force the
door a. into the taper opening of the frame c', and such opening is thereby closed Bo
as to prevent the passage of air or gases. When the door is to be opened, the nuts m
and set screws i. are turned in the reverse direction, the door is loosened from the taper
opening in the frame c', the studs n. are swung aside; and the door can then be
opened.
1 do not confine myself to the particular arrangement above described as it will
be obvious that many modifications may be made without departing from my
invention.
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. Doors provided with movable hinges so as to allow all parts of the circum-
ference of such doors to be forced into contact with the edges of the opening in the
door frame substantially as set forth.
Second. The combination with doors, of hinges and securing bars provided with
traversing appliances for securing and loosening such door substantially as set forth.
Third. In combination with doors movable hinges constructed and operating
substantially as set forth.
