PROVISIONAL SPECIFICATION.
Improvements in Glazing Roofing and the like.
We, JOSEPH ELLIS WILLIAMS of 3 Broad Street Buildings, London, Engineer,
WILFRED NEVILE FREDERIC KEMPTHORNE of 3 Broad Street Buildings,
London, Sanitary Engineer, and JOHN EDGCUMBE-RENDLE of 21 St. Maur
Road, Fulham, London, Engineer, do hereby declare the nature of this invention
to be as follows:-
Our invention relates to improved methods of glazing or fixing glass slates tin
plates or other rigid or semi-rigid transparent or opaque or semi-opaque material
that may be used for roofing areas unenclosed or enclosed by walls or partitions
also for walls or partitions for weatherproof or other purposes such glass slates
tin-plates or other rigid or semi-rigid transparent or opaque or semi-opaque
material for the purposes herein before set forth shall be hereinafter styled
roofing-plate.
It has been the practice hitherto of letting each roofing plate overlap a portion
of the roofing plate immediately below it or next it and make what is termed a
lap-joint. Our invention has for its object the doing away with this lap-joint.
We carry our invention into practice in manner as follows:
Between each roofing-plate is introduced a Z shaped butting piece shaped
somewhat in section as the letter Z and is so placed relatively to any two roofing
plates or parts corresponding to roofing-plates in such a manner that one of the
roofing plates rests on the lower horizontal limb of the Z and the other of the
roofing plates is overlapped by the upper horizontal limb of the Z the butting
edges of the two roofing plates being separated by the inclined limb of the Z
That part of the Z butting piece which is parallel to the surfaces of the
roofing plates may be curved in such a manner that it will tend to carry off
water into any channels that may be desirable or on the Z shaped butting piece
may be formed channels to catch water running down the roofing plates.
The shaped butting piece may be made of any suitable metal or china
earthenware, felt or any other suitable material.

Improvements in Glazing Roofing and the like.
We JOSEPH ELLIS WILLIAMS of 3 Broad Street Buildings London Engineer
WILFRED NEVILE FREDERIC KEMPTHORNE of 3 Broad Street Buildings
London Engineer and JOHN EDGCUMBE-RENDLE of 21 St. Maur Road, Fulham,
London 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 :-
Our invention relates to improvements in fixing glass slates tin-plates or other

page_text: rigid or semi-rigid transparent or opaque material that may be used for roofing
enclosed or unenclosed spaces and also for fixing the before mentioned materials
in walls or partitions in a manner to resist atmospheric or other agencies such
as rain snow sleet and the like or in other words to be weathertight.
In order that our invention & the method whereby the same is carried into
practice may be clearly understood & comprehended we annex hereto one sheet
of explanatory drawings the said drawings are to be taken as part of this
Specification & read in with same like letters refer to like parts in all the
drawings.
On referring to the figures,
Figure 1. is a sectional elevation of a roof showing joints hereinafter referred to
in position, the joint shows a rectangular jointing-plate.
Figure 2. is a plan of said roof.
Figure 3. is an enlarged section of the joint.
A is a plate of glass or other roofing material which will be hereinafter referred
to as the lower or overlapped plate.
B is the upper or underlapped plate.
C. E. D is the jointing-plate which is the subject of our invention & will be
hereinafter referred to as the jointing-plate, it may consist of metal earthenware
glass or other suitable material & may be made of any required shape or contour
to suit the form of roofing or other material and is composed essentially of a
part C. which overlaps the whole or part of the lower edge of the plate A-a part E
which passes between the overlapped and underlapped plates A. B. and a part D
which underlaps the whole or part of the upper edge of the plate B.
The top and bottom edges F. G. of the jointing-plate may be curved in any
required direction and may have chanuels formed on or near their edges so as to
convey water or moisture into any suitable shoots or channels.
Having now described and particularly ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is,
1. The making of joints between materials used for roofing and the like in the
manner and for the purpose substantially as herein described and set forth.
2. The use of a joint substantially as herein shown and described for making
weathertight all descriptions of rigid or semi-rigid material that may be used for
roofing or other like purposes.
