Improved Lintel for Detachable Doors or Windows.
Year: 1897

page_text: Improved Lintel for Detachable Doors or Windows.
I, HARRY MASON, of Hanover Street, Bolton, in the County of Lancaster, Builders'
Merchant, do hereby declare the nature of this invention to be as follows:-
That is to say-It relates to an improved lintel or support for the wall above a
door-way or window opening, and consists in forming or constructing said lintel or
support in such a manner that its fitting or walling into the wall may be carried out
as readily as the fitting or walling therein of any of the simple pieces of timber,
stone or other common kinds of lintels, while it affords ample space for the lifting of
the door or window into it to enable same to be readily removed or detached as may
be desired.
In accordance with my invention I construct the lintel or support of cast metal, the
front portion of which lends itself for ornamentation while to this said portion I
secure (as by forming it integrally therewith) another or horizontal part at or near
the upper edge of the former so that sufficient and appropriate space is afforded for
the walling of the brick-work wall thereon.
Beneath the said horizontal part is formed or secured a flange to extend downward
in order to hold the door or window when in position while it also forms a cavity
into which the door or window may be raised when being placed into or out of
position, or this flange may be displaced by separate pendant pieces suitably
strengthened to answer the purpose desired of them.
By constructing the lintels or supports as above described the doors they hold in
position require no other framework for this purpose other than a holding piece on
each side near or approaching their bottom parts, while the detachment or removal
of such doors may be readily effected by the insertion of any suitable instrument, as
the thin edge of a shovel's mouth, beneath their lower edges thereby raising them so
that they may have their upper edges lifted into the hollow spaces in the lintels
until their said lower edges are above and clear of the holding pieces referred to.
Dated this 28th day of September 1897.
I, HARRY MASON, of Hanover Street, Bolton, in the County of Lancaster, Builders'
Merchant, 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 that is to say :-

In the accompanying sheets of drawings:
-
Fig. 1 is a front elevation illustrating my improved lintel in position and as in
connection with an opening for a door.
Fig. 2 is a sectional side elevation on line A-B of Fig. 1.
Fig. 3 is a back elevation of the lintel and shows how it overhangs the upper end
of the door.
Fig. 4 is a similar elevation to Fig. 3 but illustrates a modification of construction
hereinafter explained.
Fig. 5 is a sectional side elevation illustrative of the modified form shown by
Fig. 4.
Fig. 6 is a back elevation showing another modified form of lintel.
Fig. 7 is a drawing in detail, drawn to an enlarged scale, of a part used in con.
nection with my improved lintel as hereinafter explained.
In carrying my invention into effect I construct the support or lintel a of cast
metal, the front portion of which lends itself for ornamentation as shown by Fig. 1,
while to this said front part I secure another or horizontal part or flange b (as by
forming it integrally therewith as shown in all the drawings or I might attach them
together by bolts or otherwise) at or near the upper edge of the part a so that
sufficient and appropriate space is afforded for the walling of the brickwork wall
thereon as shown by Fig. 2.
Beneath the flange a is formed or secured (as by bolts d) another flange f which is
inade to extend downward in order to hold the door g (or in place of said door a
window if such is desired to be used) when in position, while it also forms a cavity h
into which the door g may be raised when being placed into or out of position (see
Fig. 5) or this flange ƒ may be displaced by separate pendant pieces k suitably
strengthened as by the ribs m to answer the purposes desired of them.
By constructing the lintels or supports a as above described the doors g which they
hold in position require no framework for this purpose other than a holding
piece ppl on each side near or approaching their lower ends (shown in detail Fig. 7),
while the detachment or removal of such doors may be readily effected by the
insertion of any suitable instrument, as the thin edge of a shovel's mouth, beneath
their lower edges thereby raising them so that they may have their upper edges
lifted into the hollow spaces h until their said lower edges are above and clear of the
holding pieces p referred to and as shown by Fig. 5.
Having now particularly described and ascertained the nature of my said.
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. Lintels or supports extending across openings for detachable doors or windows,
the same being constructed substantially as herein specified and for the purpose set
forth.
2. Lintels and parts in connection therewith formed and constructed substantially
as herein specified
