Year: 1861

page_text: LETTERS PATENT to John Drew, of Hatton Garden, in the County of
Middlesex, Builder, for the Invention of "IMPROVED APPARATUSES TO BE
EMPLOYED FOR SUPPORTING STRUCTURES WHILE INSERTING GIRDERS THEREIN."
Sealed the 31st October 1861, and dated the 6th May 1861.
PROVISIONAL SPECIFICATION left by the said John Drew at the
Office of the Commissioners of Patents, with his Petition, on the 6th
May 1861.
I, JOHN DREW, of Hatton Garden, in the County of Middlesex, Builder, do
hereby declare the nature of the said Invention for "IMPROVED APPARATUSES TO
BE EMPLOYED POR SUPPORTING STRUCTURES WHILE INSERTING GIRDERS THEREIN," to
be as follows:-
My apparatuses consist of metal supports constructed with a foot or base,
an upright rising from the back thereof, and an arm or rest carried out
parallel with the base. There is also a movable pillar for inserting between
the open ends of the horizontal arms, or base and arm when additional
strength is necessary. A tightening screw is used for regulating the pressure
on the pillar.
By means of my apparatuses all ordinary shoring may be dispensed with,
the apparatuses themselves being inserted at intervals into the wall, the base.

between the upright and the front pillar, if the latter be required; and when
the girders are supported upon their columns the apparatuses are removed.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Drew in the Great Seal Patent Office on the 6th
November 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN

me, the said John Drew, Her special licence that I, the said John Drew,
my executors, administrators, and assigns, or such others, as I, the said
John Drew, my executors, administrators, and assigns, should at any

after during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVED
APPARATUSES TO BE. EMPLOYED. FOR. SUPPORTING STRUCTURES WHILE INSERTING
GIRDERS THEREIN," upon the condition (amongst others) that I, the said John
Drew, my executors or administrators, by an instrument in writing under my,
or their, or one of their hands and seals, should particularly describe and

NOW KNOW YE, that I, the said John Drew, do hereby declare the
nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement thereof, reference being to the Drawings hereunto annexed, that
is to say:
My apparatuses consist of metal supports constructed with a foot or base,
an upright, rising from the back thereof, and an arm or rest carried out
parallel with the base. There is-also-a-movable pillar for inserting between

page_text: the open ends of the horizontal arms, or base and arm, when additional
strength is necessary. A tightening screw is used for regulating the pressure
on the pillar.
Figure 1 of the accompanying Drawings is a perspective view of an appa-
5 ratus constructed according to my Invention. a is the foot or base, b is the
upright, and c the arm parallel with the base; d is a butt on the base a, and e
is a butt on the arm c; fis the pillar resting on the butt d and entering
a hole formed in the butt e; g is a screw for regulating the pressure;
Figure 2 is a front elevation, and Figure 3 a vertical section showing the
o apparatuses applied to a building. h, h, are the girders passing through the
apparatuses, as before described.
By means of my apparatuses all ordinary shoring may be dispensed with,
the apparatuses themselves being inserted at intervals into the wall, as shown
at Figure 2, the base a thereof resting upon the brickwork. The girders are
5 inserted in the space between the upright 6 and the front pillar f, if the latter
be required, and when the girders are supported upon their columns the
apparatuses are drawn out and removed.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim, the improved
O apparatuses for supporting structures while inserting girders therein, con-
structed substantially in manner herein-before described and illustrated in
the accompanying Drawings.
In witness whereof, I, the said John Drew, have hereunto set my hand
and seal, this Sixth day of November, One thousand eight hundred
and sixty-one.
