other Portions of Buildings or Structures.
THOMAS ROBERT SHELLEY South Road Smethwick near Birmingham, County
Stafford patentee and contractor, do hereby declare the nature of this invention to be
as follows:-
:-
My invention consists of a new method of securing zinc or other metals to
roofs or other portions of buildings or structures, which dispenses with the use of
wooden rolls, and all outside fastenings leaving full allowance for expansion and
contraction of the metal. *
In carrying out my invention I take a sheet of metal and lay it on the
structure to be covered, having previously given a half circular or other corrugation
on each side of the sheet of metal at the edges, through one of these corrugations
at certain intervals 1 punch an elongated slot, and thro this 1 pass a screw with a large
head, the screw being firmly secured into the boards or rafters forming the structure;
I then take another sheet and place it in position so that the corrugation on the
opposite edge covers the one thro' which the screw has been driven, at similar
distances to the screws on the inner side of the top corrugation I have short pieces
of metal bent to a less radius than the outer corrugation and punched with an
elongated slot with widened out piece to admit on pressure of the head of the
screw already fixed to be forced thro' same the sheet is then forced down the
slope of roof or other structure & the head of the screw is gripped by the narrowed
portion of the slot thus securing the portion of the sheet with the outer corruga-
tion-the short pieces of metal having been secured at the edges with solder or by
other means to the under side of the outer or larger corrugation.
The sheets are thus firmly fixed in position and prevented from slipping down
by the screw that is already described; the slots & punctured pieces, already
described give free allowance for expansion and contraction & the horizontal joints
of the sheets when they overlap each other in the case of deep roofs &c. will be made
by the usual lap already universally used.
I claim the combination of the screw, with the elongated slot, and inner piece
secured to the corrugation and the several independent & combined uses made of
same, for securing the sheets in position and allowing for expansion & contraction
without outside fastenings.

THOMAS ROBERT SHELLEY South Road, Smethwick near Birmingham County of
Stafford Patentee and Contractor, 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 :-
My invention has for its object to secure zinc or other metallic substances to roofs
or other portions of buildings or structures, and dispensing with wood rolls, and all
outside fastenings, giving full allowance for the expansion and contraction of the
Metal. I effect these objects by forming the sheets or pieces and fixing same in the
manner hereinafter described.
I take a sheet of metal and lay it on the structure to be covered, having previously
given a half circular or other corrugation, on each side of this sheet of metal at the
edges, the corrugation on one side being larger than at the other. Through the
smaller of these corrugations at certain intervals, I punch a round or elongated slot,
and thro' this I pass a screw with large head the screw being firmly secured into the
boards or rafters or purlins forming the structure. I then take another sheet and
place it in position, so that the large corrugation covers the one, that has had the
screws driven through it; In order to secure the side of the sheet on which the
larger corrugation has been formed, at similar distances to the screws I secure on
the underside of the larger corrugation short pieces of metal, bent to a radius between
the small and large corrugations, and punched with an elongated slot, with a widened
out end this is made to admit, on pressure being brought to bear on the outside
piece, the head of the screw before mentioned passing thro the widened out piece, by
a sliding motion being then given, lengthwise of the sheet, the narrowset portion of
the slot grips the underside of the heads of the screw and this firmly holds the sheet
down.
j
Some times it may be advisable to form the slot in another way, as described by
dispensing with the widened out piece, and having an open jaw gradually tapering to
the end the sheets are thus securely fixed in position and prevented from slipping
down, by the screws that are passed through the sides on which the smaller corruga-
tion is formed, and full allowance is given for expansion and contraction―The lap or
drips in case of long lengths will be made by the usual lap already universally
used.
Although I have only described my invention with respect to roofing, yet my said
invention may also be applied to vertical sides, or to ceilings. It will be observed the
edges of the outer and inner corrugations dont come in actual contact with the
boarding or zinc, unless compelled to do so by pressure in fixing, so that there is
always a tendency to press against the head of the screw.
Figure 1 of the accompanying drawing represents in cross section a portion of

page_text: a sheet of zinc with the larger corrugation, and a portion of another sheet with the
smaller corrugation it also represents an end view of the metal with the slot before
described-a. a. is the sheet of metal with the outer or larger corrugation. b. b. is
another sheet with the opposite or smaller corrugation shewn, c is the metal piece
referred to secured to the sides of the larger corrugation d is one of the screws passed
through the hole into the wood or iron purlin or rafters &c. e. is the round or
elongated hole in the smaller corrugation-f is the boarding composing the roof, or
rafters or purlins, g. h. is the slot thro which the screw passes in the piece of metal.
Figure 2. represents the short piece of metal. g. is the elongated slot. h. is the
widened out part to admit of the screw head passing through. a. a. represents the
sheet and the underside of the larger corrugation.
Figure 3. represents the smaller corrugation with the elongated slot and screw in
position. b. b. represents the sheet of metal and the corrugation. e. is the round or
elongated hole in the corrugation. d. is the screw one of a series securing the sheet ;
fis the boarding.
Figure 4. is a plan of the small metal pieces shewing the slot. c is the metal
piece. g. the slot, h the widened out piece to enable screw to pass through.
Figure 5. represents another form of metal piece. j is the widened out piece,
g is the portion of slot that grips the head of the screw. These pieces are spaced at
various distances about 3 ft. apart.
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.―
First. The elongated slots, marked on the drawings used substantially in the ways
described and illustrated..
Secondly. The application of the larger and smaller corrugations, used as described
and for the several purposes only as shewn.
Thirdly. The application of the screw head to secure the top sheet in position as
described.
