I JAMES HILTON of 108 Oldham Road Shaw near Oldham in the County of
Lancaster Builder do hereby declare the nature of this invention to be as follows:-
This invention relates principally to the fireproofing of existing mills or manu-
factories which are built with wooden beams and joists, and consists of an improved
mothod of rendering such buildings fireproof without removing the existing floors
beams or pillars and without removing or otherwise disturbing the machinery; thus
preventing fires from spreading from one room or floor to another and at the same
time adding strengh to the existing floors and making the same more rigid.
The improved method of fire proofing consists principally in applying a wrought
iron casing to the beams and securing the same to the beams and pillars by means of
wrought or cast iron brackets and other fixings.
The casings are made preferably of two side plates and a base plate, the two side
plates being double angle iron bolted through the beam and the base plate underneath
the beam secured to the angle iron by means of bolts or rivets.
1 then put in H or T-iron joists from beam to beam, or from wall to beam or from
wall to wall as the case may be, and secure the same by bolts or other suitable means.
1 then fit in between these with concrete or with bricks or slabs specially made to fit
the spaces, or with small arches or concrete blocks or other non-combustible material
and I lastly plaster the whole underneath so as to completely cover up the iron joists
thus preventing any direct action of the fire thereon.
This improved method of fire proofing will only diminish the original height of the
rooms by about five inches and also by fireproofing the underside of the roof in the
same manner the rooms will be kept at a more even temperature and the expense of
insuring the building and machinery will be thereby greatly reduced.

page_text: I JAMES HILTON of 108 Oldham Road Shaw near Oldham in the County of
Lancaster Builder 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 principally to the fire-proofing of existing mills or manu-
factories which are built with wooden beams and joists, and consists of an improved
method of rendering such buildings fireproof without removing the existing floors
beams or pillars, and without removing or otherwise disturbing the machinery; thus
preventing fires from spreading from one room or floor to another and at the same
time adding strength to the existing floors and making the same more rigid.
The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the annexed sheet of drawings and the following explanation thereof.
Fig. 1. on the annexed drawings is a vertical section of part of the floor of a mill
or building with wooden beams and joists which has been rendered fireproof by the
application of my invention thereto, the section being taken across the joists.
Fig. 2 is a similar section taken at right angles to the former or across the beams,
Fig. 3 is a plan view of the same taken from beneath and Fig. 4 is a section (drawn
to a larger scale) of one of the beams showing more clearly the method of casing the
same, a are the cast iron columns the wooden beams, and c the wooden joists.
The improved method of fireproofing consists principally in applying a wrought
iron casing to the wooden beams b, and securing the same to the beams and pillars a
by means of wrought or cast iron brackets and other fixings. The casings are made
preferably of two sideplates d and a base plate e the two side plates being double
angle iron bolted through the beam at f and the base plate underneath the beam
secured to the angle iron by means of bolts or rivets g. I then put in H or T-iron
joists (see Fig. 1.) from bean to beam, and from wall to beam, or from wall to wall
as the case may be, and secure the same by bolts or other suitable means.

I then fill in between these iron joists with concrete or with bricks or slabs i
specially made to fit the spaces, or with small arches or concrete blocks or other non-
combustible material, and I lastly plaster the whole underneath so as to completely
cover up the iron joists h thus preventing any direct action of the fire thereon..
This improved method of fireproofing will only diminish the original height of the
rooms by about five inches that is the thickness of the concreto or slabs i, and also by
fireproofing the underside of the roof in the same manner the rooms will be kept
at a more even temperature and the expense of insuring the building and machinery
will be thereby greatly reduced.

page_text: 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 :-
The improved method of fireproofing mills or other buildings having wooden beams
and joists, by applying thereto a casing of wrought iron combined with iron joists
and with concrete, or with bricks or slabs of non-combustible material substantially
in the manner herein before described and illustrated by the drawings annexed.
