Improvements in Metallic Roofing.
I, SAMUEL CARPER FREDERICK, of Arcadia, in the County of Crawford and State
of Kansas, United States of America, gentleman 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 metallic rooting. The object is to produce a metallic
roofing which may be constructed at a small cost, which shall be exceedingly strong
and durable in use and will not be liable to get out of repair.
With these objects in view the invention consists in the novel construction and com-
bination of parts of a metallic roofing as will be hereinafter fully set forth in the
specification, illustrated in the drawings, and more particularly pointed out in the
claims.
.
In the accompanying drawings forming part of this specification and in which like
letters of reference indicate corresponding parts I have illustrated one form of device
embodying my invention although the same may be carried into effect in other ways
without in the least departing from the spirit thereof, and in these drawings.
Fig. 1 is a perspective view of the upper side of the roof showing the flanged
supports on which the material composing the roofing rests and a packing to be placed
between the joints of the sheets to present a water-tight joint.
Fig. 2 is a perspective view of the bottom of the roof, showing a tie-rod for
giving additional strength to the roofing and a block placed under the said tie-rod
pressing against the joints of the roofing.
Fig. 3 is a detail perspective view of the flanged support and
Fig. 4 is a detail view of the packing placed between the joints of the sheets
composing the roofing.
Referring to the drawings A designates the flanged support upon which the sheets
of metal B composing the roofing rest. It will be observed that this support is
shaped like an inverted T, the same being made of sheet metal but preferably of
heavy sheet iron. The upper portion of this flange is formed into a tube 6 through
which passes a rod C designed to support the roofing.
D designates the tie-rod designed to act as an additional support for the roofing,
the ends of which are secured to the rafters of the roof. At a point preferably near
the centre of this tie-rod is placed a block E designed to rest against one of the
joints of the roofing under the flanged support so that when the nuts c on the ends
of the rods are tightened the block will be forced up and thus prevent the roofing
from sagging.
Where the roof is very large and heavy two or more of these tie-
rods may be employed, the same extending from the rafter in one end of the roof to
that of the other end, the block, as before stated, being in the center.
F designates a flanged packing, which may be made of any suitable material but
preferably of wood, designed to be placed between the joints of the sheets B of which
the roofing is constructed, so that in case of rain or snow, the moisture will cause the
same to expand and thus produce a water tight joint.

page_text: One end of the packing has its upper flange projecting beyond the other portion
thereof to enable it to lap or rest upon the separating part between adjoining series of
roof plates.
In constructing the roofing a number of the rods C having the flanged support A
placed thereon are secured in position, the flanged portion being on the under side and
the tube portion on the upper side as described.
The sheets of metal B of which the roofing is composed, are then placed in position,
and between each sheet is placed one of the flanged packings F. the flange over-
lapping the said edges of the sheets. Then another sheet of the roofing, and then
another packing and so on until the roofing has been completed. At the bottom
and top of the roof or at the comb and eaves, the sheet metal may be bent down and
secured by nails in the manner usually employed in ordinary tin roofing.
The tie rods D are then placed in position with the block E resting under the
joints of the flanged supports and the nuts c on the ends of the said tie-rods are
tightened, thus forcing the block up against the roofing to prevent the same from
sagging from the weight of snow or from any other cause.
The number of tie-rods as before stated, may be varied according to the size of
the roof, and at the points where the sheets rest against the flanged supports the
same may be soldered to prevent the entrance of moisture at that point.
It will thus be seen that by this construction an exceedingly cheap and durable
roof may be made and one that will not be liable to get out of repair and which
will be practically fire-proof.
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. The roof comprising the series of roof-plates and the packing-bars placed
between the edges of the same and having upper and lower flanges and expansible
under the action of moisture, substantially as and for the purpose set forth.
2. The roof comprising the series of roof plates and packing bars placed between
the edges of said plates and having upper and lower flanges, said packing-bars being
expansible under the action of moisture and each having one end of its upper
flange extending beyond its outer portion substantially as set forth.
