PROVISIONAL SPECIFICATION.
Novel Construction of Hinges with Stays or Plates for Ledge Doors.
I, JOSEPH TALL, of Belvoir Road, Lordship Lane, Dulwich, Surrey, Architect and
Consulting Surveyor for Portland Cement Concrete Buildings, do hereby declare the
nature of this invention to be as follows:-
"
This invention relates to constructing hinges with stays, straps, or plates and in
such a manner that the boards to form the door can be secured in close order "filleted"
or chamfered " either before or after the hinges are affixed to the door stiles. The
stays, straps, or plates can be each in one piece with the hinges, or they can be secured
to them; and in some cases they can be shaped to receive the bolts, or other fasteners.
For the purpose of my invention, I cut, cast, or roll iron, or other metal to the
required length forming one end with eyes or ears for the pintle and with the stays,
straps, or plates as part of same. The metal can be slit for a greater part of its length
to form one or more loops, or be cast with a loop or loops on the back, or the loop
or loops may be secured to a strip to constitute the stay or plate.
The hinges, according to my invention, have holes in the strips at given distances
apart to suit the width of boards to be affixed to them, and to ensure great strength,
the hinge strips can be the full width of the door opening and in such cases the door
is prevented from buckling or warping.

COMPLETE SPECIFICATION.
Novel Construction of Hinges with Stays or Plates for Ledge Doors.
I, JOSEPH TALL of Belvoir Road, Lordship Lane, Dulwich, Surrey, Architect and
Consulting Surveyor for Portland Cement Concrete Buildings, 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 constructing hinges with stays, straps, or plates, and in
such a
manner that the boards to form the door can be secured in close order
"filleted
or "chamfered," either before or after the hinges are affixed to the door
stiles. The stays, straps, or plates can be each in one piece with the hinges, or they
can be secured to them, and in some cases they can be shaped to receive the bolts, or
other fasteners.
My invention is clearly represented in the annexed drawings.
Figure 1 is an elevation of a Ledge door fitted in or to its frame and Figure 2 is
an end view with the hinged plates triangularly bulged by stamping or rolling.
Figure 3 is a sectional plan, and Figure 4 a partial front view of a
for a greater portion of its length and the central part bulged.
hinge plate, slit
Figure 5 is an edge view and Figure 6 an elevation of a hinge strap or plate bulged
out along the central line forming a pocket in which a bolt is arranged, the hinge
answering the double purpose of hinge and barrel bolt.
All the letters of reference refer to like parts.
A is the plate, or strap extending across the door and having all the panels or
boards B, B, attached.
C is the bulged, or ribbed portion of said strap A, the boards B, B, being filleted or
grooved into each other like ordinary match boarding.
Each strap may be in a piece with the hinge loop D, or be attached to the hinge
plate as an extension of same.

page_text: E is a bolt within the bulge of the strap A but ordinary bolts may be affixed to
the door and a Norfolk or other latch as at present and instead of the bolt strap being
in piece with, or attached to a hinge, as described with reference to Figure 6, the strap
and bolt only may be affixed to the door, the fasteners (screws or nails) being always
close to the meeting edges of the boards. By this last method, the bolt strap may
inside the door and the hinge straps outside..
be
By this invention; Ledge doors may be constructed very cheaply and expeditiously,
there being no back, cross, or angle battens, nor is any special preparation of boards
necessary for the purpose, such boards known as match boarding already prepared
being readily obtainable from any Timber Merchants Stock.
For Stable doors, gates, and the like, made on the "Ledge door" principle, such as
where additional strength, say, from increased width or thickness is necessary, I bend
round or other form of bar iron into crescent shape, such as at F, Figure 7, and
screw or bolt, such a piece to the boards B, B, preferably above the hinge A the ends
resting upon, or it may be below against the hinge, or as an intermediate, as desired.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. The construction of hinges with stays or plates across "Ledge doors" as described
and exemplified by the annexed drawings.
2. The construction of "Ledge doors" without back or inside battens but with hinge
straps as means for securing the boards in position, as described.
3. The combination strap and bolt appliance, Figure 6, with or without a hinge,
for "Ledge doors," as set forth.
