PROVISIONAL SPECIFICATION.
An Improved Fireproof Partition for Building Construction.
I, ARTHUR WILLIAM RAMMAGE of 42 Old Broad Street, in the City of London,
Engineer, do hereby declare the nature of this invention to be as follows
This my invention relates to certain new and useful improvements in fireproof
partitions and metal construction for building purposes, and which invention has for
its object to provide a partition which is fireproof, and rigid. Moreover partitions
made in accordance with this my invention are cheaper than other partitions, occupy
less space, and in comparison with their width and cost will give the greatest
amount of strength.
By this my invention I employ in combination with the channel steel or iron,
forming part of the flooring, a series of iron or steel rods of either T, L, round or
square section.
The said steel or iron rods are secured by bolts at their extremities, and at equal
distances apart to the channel irons forming part of the upper and lower flooring,
and are crossed in such a manner that they intersect midway their length. At this
point of intersection the said iron or steel rods are flattened out and are secured
together by a bolt or rivet which is passed through the flattened portions aforesaid.
The partition thus partially constructed is filled in with concrete or other fire-
resisting material to any desired thickness.
By this my invention I provide a partition which is simple in construction and
possesses greater advantages than other partitions of the same class at present
in use.

COMPLETE SPECIFICATION.
An Improved Fireproof Partition for Building Construction.
I, ARTHUR WILLIAM RAMMAGE, of 42 Old Broad Street, in the City of London,
Engineer, 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 my invention relates to certain new and useful improvements in fireproof
partitions and metal construction for building purposes, and which invention has for
its object to provide a partition which is fireproof and rigid.
By this my invention, I employ in combination with the channel steel or iron,
forming part of the flooring, a series of iron or steel rods of either T, L, round, or
square section. The said steel or iron rods are secured by bolts at their extremities,
and at distances apart to the chauuel irons forming part of the upper and lower
flooring, and are crossed in such a manner that they intersect midway their length.
At this point of intersection, the said iron or steel rods are flattened out and are
secured together by a bolt or rivet which is passed through the flattened portions
aforesaid.
My invention will be more particularly understood by reference to the annexed
drawings.
Figure 1 is an elevation of a skeleton frame constituting my invention as a partition
in a building.
Figure 2 is a transverse section of the same through the lines ab of Figure 1.
[Price 6d1

page_text: Figure 3 is a horizontal section through the line c d of Figure 1, and Figure 4
is a detached view showing how the Tee ribs are prepared to act as vertical posts
forming a doorway, also the manner by which the ends can be arranged between
channel irons to which they are rivetted and on which they sit to make their
positions very rigid.
A, A, are two walls of a building. B, B, are bearers on which two channel iron
ribs C, C, are placed and supported. These two channel irons are provided with holes
at given distances apart, their number increasing in proportion to the distance
between the two walls A, A. Near to one wall where the doorway is to be arranged,
I set two tee shaped ribs D, D, of the form shown at Figure 4, one on either side.
The upper and lower ends of these tees I have portions of the face cut away, as
indicated at E to fit against the upper and lower edges of the channel irons which
act as girders, said tees being rivetted to the flat surfaces of the two channel
irons, as indicated.
At the opposite wall, I arrange two shaped irons Fas uprights, as seen more
particularly in the sectional plan, Figure 3, portions of the ends of which are also
removed in a similar manner to that indicated with reference to the T ribs shown at
Figure 4.
Between and to these uprights F and the channel irons, I arrange a series of
metal rods or bars G, G, of the same or of varying widths, these being flattened and
perforated at the parts where they intersect each other, notably at their middle
intersections, so that they can be rivetted together and form a network, leaving
openings for the reception of fireproof, or other plaster which is floated or smoothed
on both sides of the metal work to prevent the spread of fire, said plaster with the
ironwork embedded acting together for that purpose and for producing great
strength.
The channel irons C, C, form bearers, for cross girders or ribs H, as seen at
Figure 2, and on these an ordinary wooden floor J can be carried.
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 preparation and employment of Land T shaped metal bars as uprights,
and their attachment to and between channel iron bars as girders when applied in
connection with partitions and have concrete, or other fireproof plaster as a covering
or coating in connection therewith.
2. The employment of two channel irons as girders having affixed between and to
them rods or bars of any shape but having flattened portions at the parts arranged
between the channel irons, and at the parts where they intersect each other and are
secured together, as and for the purpose set forth.
