PROVISIONAL SPECIFICATION.
Improvements connected with the Method or System of Securing
Sheets of Zinc or other Material for Roofing Purposes.
I, EDWARD BOYCE PODMORE, Managing Director of the Company of
Helliwell & Co. Ltd., of Brighouse, in the County of York, Patent Glaziers
and Zinc Roof Workers, do hereby declare the nature of this invention to be as
follows:-
:-
This invention consists in a new method or system of securing and fixing onto
buildings or other structures, sheets of zinc copper, lead, plain and corrugated
metal or other material.
According to my invention each side of the sheet of metal is turned upwards
and covered by a wood bar for holding down the sheets of metal. At intervals
and at suitable distances apart the wood bar is covered by a cap secured by screws
or other means, the whole being afterwards covered by a metal cover or cap. The
bottom of the first or last cap is bent downwards and in order to convey away water
or moisture the lower end of the said cap is made with a channel or groove to
convey away the moisture or water. By the formation of this channel in the outer
cap the end is not cut away as formerly and no solder is required in the formation
of the channel as the said channel is formed by turning over the edge. Whilst I
prefer the channel to form an integral part of the cap it may be made separately.
and connected by solder.

DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a geometrical view of a roof covered with my improved zinc roofing
and Fig. 2 is cross section on a larger scale.
A represents the boarding to be covered by sheets of zinc or other material B
the ends of which are bent up so as to abut against a wood bar or roll C. At
suitable distances apart upon the said wood bar is a cap D made secure by screws
or other means the whole being afterwards covered by a continuous metal cap or
cover E. The bottom end of this cap E is bent downwards as shewn at F and in
order to convey away water or moisture from the roof the lower end of the
sheet B to catch the moisture is made with a channel or groove G. This channel G
is shewn on a larger scale in Figs. 3 and 4 which are respectively plan and front
view of same.
By the formation of this channel in the bottom sheet the end is not cut away as
formerly and no solder is required in the formation of the channel as the
said channel is formed by turning up the edge. Whilst I prefer the channel to
form an integral part of the cap it may be made separately and connected by
solder.
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 :-
In zinc roofing, the use therein of sheets B having turned up edges, for abutting
against the woods bars C together with turned up edges G to receive and convey
away moisture, in combination with cap D and secondary cap E, all arranged and
employed in the manner and for purposes described.
