Copper or other Metals for Roofing Purposes.
CHARLES JOSEPH LATTER Nazing Lodge Bounds Green London N. Metal Plate
Worker do hereby declare the nature of my invention for IMPROVEMENTS IN THE
METHOD OF FIXING SHEETS AND ROLLCAPS OF COPPER OR OTHER METALS FOR ROOFING
PURPOSES to be as follows:-
This invention has reference to the means employed in covering the surfaces of
flats, curbs, or other portions of roofs of buildings with sheets of copper or other
metals. My improvement therein consists in the method of securing the sheets and
the roll-caps in position and at the same time making them watertight without
making holes in the substance of the metal or using any external fastenings or
soldering any part together thus leaving all the parts free to expand or contract
with the variations of temperature. For the purpose of my invention the sheets of
copper or other metals are prepared by having three of their sides turned upwards
and one side prepared for welting on to gutter or edge of drip, the corners of the
lower end of the sheets being stretched or bossed round the end of the wood roll
and the upper corners of the sheets being folded up and turned behind the end of
the wood roll the sides of the sheets being secured to the wood rolls by means of
strips of metal passing under the wood roll at suitable intervals and being securely
nailed or screwed to the roof, the clip or strip of metal then being brought up the
sides of the wood roll, and turned over the edge of the sides of the sheets. As a part
of my invention, I then prepare the roll-cap with a double or folded-edge along each
side and at about the middle I insert and fold up with the cap an interior piece of sheet
copper with a projecting tongue or fork on each side. These forks are made to slide

page_text: into the turned over portion of the clip previously described and they thus hold both
the sheets and the roll-caps perfectly secure and without the use of solder which has
been hitherto used for the purpose. For another part of my invention I also prepare
a saddle end of the roll cap where the cap abuts against a drip or wall by stretching
or bossing up a flange from the roll cap itself and securing thereto a saddle piece
with the edges folded back and over the flange thrown up from the roll cap thus
joining the two pieces together by a secure and perfectly watertight joint and without
any deterioration of the substance of the metal such as would be caused by stamping
or pressing out of the solid.

CHARLES JOSEPH LATTER of Nazing Lodge, Bounds Green, London. N., Metal
Worker 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 has reference to the means employed in covering the surfaces of
Flats, Curbs or other portions of roofs of Buildings with sheets and roll caps of
Copper or other Metals.
My improvements therein consest in the method of securing the sheets of copper
or other inetal and the roll caps for the same in position on the roof without making
any holes in the substance of the metals or using any external fastenings or soldering
any parts together, thus leaving the sheets and other parts free to expand or contract
with the variation of temperature while being at the same time perfectly watertight.
Such being the nature and object of my invention I will now describe the methods
by which my improvements are carried out.
For the purposes of my invention the sheets of copper or other metal are prepared
by having three of their sides turned upwards, and one side prepared for welting on
to the gutter or edge of drip, the corners of the lower end of the sheets being
stretched or bossed round the end of the wood roll, the sides of the sheet being
secured to the wood rolls by means of strips of copper (or other metal) passing under
the wood roll at suitable distances and being securely nailed or screwed to the roof,
the clip or strip of metal then being brought up the sides of the wood roll and turned
over the edge of the sides of the sheets.
I then prepare as a part of my invention the roll caps with a double or folded edge
along each side as Fig. B on accompanying drawing and at about the middle I insert
and fold up with the cap an interior peice of Sheet copper (or other metal) with
projecting forks on each side as Fig. A. these forks being made to slide into the
turned over portion of the clips previously described, thus holding both the sheets
and the rollcap perfectly secure and without the use of Solder which has been hitherto
used for this purpose.
·
I also prepare for another part of my invention a saddle end for the rollcap where
the same abuts against a drip or wall, by stretching or bossing up a flange from the
rollcap itself and securing thereto a saddle peice with the edges folded back and over
the flange thrown up from the roll cap, thus joining the two peices together by a
secure and perfectly watertight joint and without any deterioration of the substance
of the metal such as would be caused by heating for the purpose of stamping or
pressing out of the solid.

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-
Firstly. The employment of the interior forked peice of metal Fig. A in combina-
tion with the double or folded edged roll cap as figure B. for the purpose of securing
the roll cap to the roof by sliding into the holding down clips before described
substantially as set forth.
Secondly. The combination of the folded saddle peice D with the flanged end of the
rollcap E in such manner that when used against a drip or wall the same shall be a
perfectly watertight joint substantially as herein shewn and described.
