Improvements in Metallic Trough Floors.
I, MICHAEL FRANCIS XAVIER FOLEY, of 13th Street, Philadelphia, U.S.A.,
Civil Engineer, do hereby declare the nature of this invention to be as follows:-
The floor of this invention is composed of iron or steel troughs comprising a
bottom channel or a double tee beam placed horizontally; two flat side plates
rivetted at their bottom edges to the bottom edges or shoulders of the bottom
beam; and between the main trough parts thus formed, an intermediate channel
or double tee beam forming a shallow trough between two larger troughs and
bracing these together by rivetting at the top or outer edges so that all the rivetting
can be done by a rivetting machine.
The troughs may be filled in with cement for supporting the floor of a building
and a ceiling may be attached to the bottom of the main troughs by screw bolts.
In the case of railway bridges the main troughs may carry the sleepers embedded
in cement.

Improvements in Metallic Trough Floors.
1, MICHAEL FRANCIS XAVIER FOLEY of 13th Street Philadelphia, U.S.A.,
Civil 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 invention relates to metal trough floors for bridges and large buildings.
In the accompanying drawing Fig. 1 is a cross section of a floor of a railway
bridge constructed in accordance with the invention by combining channel beams
and flat plates. Fig. 2 a like view with a construction of double tee beams and
flat plates. Fig. 3 is a vertical cross section of a floor suitable for a building.
A are iron or steel channel beams of the ordinary pattern and of any convenient
size. B flat iron or steel plates rivetted to the channel beams at right angles
thereto. C ballast placed in the troughs formed by the union of the plates and
beams. D railway sleepers. E a short length of railway rail.
In Fig. 2 A' are double tee beams used in place of the channel beams shewn in
Fig. 1.
In Fig. 3, C is the concrete or other suitable material used for a filling when
constructing the floor of a building. F the ceiling secured to the trough floor
by bolts or other suitable means.

page_text: When the floors are made by joining together channel or double tee beams
and flat plates as shewn, the sections that are put together at the workshop can
have all the rivetting done by machinery, the only hand rivetting required being
that necessary to join the several sections when they are placed together and this
hand rivetting can be easily and quickly done.
In the case of floors designed to carry heavy weights double tee beams A' may
be used instead of the channel beams A.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. In a metallic floor, the combination of the trough shaped beams with plates
connecting said beams and secured thereto along both edges thereof, to the out-
wardiy projecting flanges on the beams, in such positions as to permit the gripping
and rivetting of the flange and plate by a rivetting machine, substantially as
described and shewn.
2. A metallic trough floor composed of a series of flanged beams and flat plates
joined together, the said beams being fastened to the edges of the plates in such
a position that the flanges through which the rivets are driven project outwardly
and allow the said flanges and plates to be gripped by a rivetting machine,
substantially as described and shewn..
3. In a metallic trough floor the combination of the double tee beams A' with
flat plates B, the flat plates being rivetted along both edges thereof to the outer
flanges on the double- tee beams, substantially as described and shewn.
Dated this 6th day of August 1897.
