page_text: I, WILLIAM BARRACLOUGH, of Providence foundry, Stanningly, in the county of
York, Ironfounder, do hereby declare the nature of this invention to be as
follows:-
It consists of a particular construction of Cast Metal Door (or doors) and Frame
by means of which construction such doors and frames may be hinged together or
separated without the use, addition, or intervention of loose or separate Bolts,
Rivets, Pins, Screws or Cotters.
The essential principle of this invention is that each door and frame possess in
themselves the necessary members for forming a self adjusting or separating hinge
without the aid of additional appliances or of an artificer, such as a mechanic or
blacksmith.
This particular construction may be thus described.
Upon the face of the door frame and projecting from it there are two (or more)
horizontal "Lugs" or "Ears" in vertical relations to each other; each of which
projecting members contains a hole, either drilled or cast in it-the said holes
and "Ears" being designed as sockets and bearings for the upright or vertical pins
or pivots which are attached to each door and upon which pivots the door revolves.
These "Lugs" or 'Ears" are situated upon either the right or left side of the
frame, or, in the case of double doors being required within one frame, upon both
right and left sides. On the upper and lower margin of each door there are two
metal pins of differing lengths and configuration, for insertion within the holes of
the "Ears" and intended as Pivots upon which to revolve the door. The upper-
most pin is longer than the lower one and different to it in form. The lower
pin is of uniform thickness but the upper one has a head and neck which
contribute important helps in uniting and adjusting the door and frame. There
are also flanges which assist these processes as well.
In the case of a single door and frame the whole apparatus may consist of only
two parts or castings and in that of a double door and frame, of three parts or

page_text: castings; all self adjusting; or the doors may be furnished-if required-with
latches, handles etc. They may be made of Cast Iron or Steel or other Metal.
The primary object of this invention is cheapness and simplicity in constructing
and simplicity in removing and repairing Furnace doors for Washing-houses,
Domestic Sculleries, Greenhouses etcetera, but is not limited, to those purposes-
being designed for application to such structures as Cooking Ranges, Bakers Ovens,
Shop, Gas and other Heating Stoves, Soot Holes, Flues, Closets or other similar
receptacles.

page_text: An Improved Cast Metal Door and Frame for Furnaces, Grates,
and the like.
I, WILLIAM BARRACLOUGH, of Providence Foundry, Stanningley, in the County
of York, Ironfounder do hereby declare the nature of my invention for AN
IMPROVED CAST METAL DOOR & FRAME FOR FURNACES, GRATES AND THE LIKE
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
It consists of a particular construction of Cast Metal Door (or doors) and Frame
by means of which peculiarity of construction such doors and frames may be readily
hinged together or separated without the use, addition, or intervention of loose or
separate Bolts, Rivets, Pins, Screws or Cotters.
The essential principle of this invention is, that each door and frame possess in
themselves the members necessary for forming an automatic Hinge (capable of
being easily separated or adjusted) without the aid of additional appliances or the
services of a skilled artificer.
"
"
This particular construction may be thus described.
Upon the face of the door frame, and projecting from it, there are two horizontal
Lugs" (or "Ears") in vertical relations to each other and each of these projecting
Ears" contains a hole which may be cast or drilled therein. These "Ears," and
the holes therein, are designed as bearers and sockets for two vertical pins which
forn part of each door and serve as pivots upon which it is revolved. These
Lugs" are situated upon either the right or left sides of the frame; or, on both
(right and left) sides of it when two doors are required within one frame.
"
The two vertical pins just referred to, as pivots upon which each door revolves
are connected with the upper and lower margins of the door and are of different
lengths and configuration. The uppermost pin is longer than the lower one and
different to it in form. The lower pin is of uniform thickness throughout, but the
upper one has a head and neck which contribute important helps in uniting and
adjusting the door and frame. There are also shoulders or flanges-upon the door
and frame-which assist in this adjustment.
In the case of a single door and frame the whole apparatus may consist of only
two parts or castings, and where two doors are required in one frame, three
castings (may) comprise the whole structure, all these parts being self adjusting.
It is not essential to this invention that the said doors should be devoid of loose or
attachable members such as knobs, latches, handles, sight bole covers, ventilators,
etc. The materials of which they are made may be cast iron or steel, or any other
suitable metal.
The primary object of this invention is, cheapness and simplicity of construction,
combined with facility in removing and repairing, Furnace doors, for Greenhouses,
Domestic Sculleries, Washing-houses, and such like premises.
It is also designed for application to such apparatuses as Cooking Ranges,
Bakers oven fittings, Shop, Gas and other Heating stoves, Soot Hole doors, Flues,
Closets, Vertical (and other) Engine fire doors, Brick Kilns, and similar uses.

page_text: To prevent misapprehension, I wish to state that I do not claim, under this
patent, the application of the principles described and illustrated herein to a
Cooking Range Convertible flue (commonly called a Combined open and close
fire"
arrangement).
"
The accompanying diagrams will enable this invention to be more thoroughly
understood and more readily carried into effect.

Fig. 1. is a perspective view of a cast metal furnace door Frame, with two
perforated Lugs" (or "Ears") A and A' and a flange with rounded end
marked C.
Fig. 2. is a view of a cast metal Furnace door, shewing the pins B and (the
particular form of) B², which said pins are designed to serve as Pivots when
inserted within the holes shewn in the "Lugs" A and A² (Fig. 1.). The rounded
shoulder, C, operates as a Lever against the rounded end of the flange Cand
assists in the working of this hinge but does not form any essential part of this
invention.
Fig. 3 shews the mode of inserting the pin B' in the perforated lug, A, prior to
the pin B being inserted in the opposite lug, A³.
Fig. 4 shews the union of the door and frame, and the positions occupied by A,
and B, also C and C.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed, I declare that what
I claim is,
In cast metal doors and Frames such as those herein described, the principle of
constructing them with a self adjusting and separating hinge substantially as--and
for the purposes-herein described.
