PROVISIONAL SPECIFICATION.
Improvements in Repairing Slated Roofs and in Means for
the same.
1, JAMES BRISTOW of Peterborough Auctioneer, do hereby declare the nature of
this Invention to be as follows:
This Invention has for its object improvements in repairing slated roofs and in
means for the same.
It is now usual in repairing slated roofs and when a new slate is required to
replace one which has fallen, to fasten this new slate in its place by strips of lead
passed beneath its lower edge and bent upwards; but experience proves that slates
so fastened are not securely held and besides the leaden strips are unsightly.
Now according to my Invention. I employ clips preferably of sheet copper and
of a T form. I take the slate which is to be inserted and notch its edges on each
side to receive the stem of such a clip whilst the head of the clip lies flat upon the
face of the slate.
The notches in the slate are formed somewhat higher up the slate than the ordinary
nail holes and in such a position that the stems of the clips when the slate is in its
place come immediately over one of the laths to which the slates are nailed. When
the clips have been inserted their stems rest flat upon the upper side of the lath and
so the new slate is securely held.

I, JAMES BRISTOw, of Peterborough, Auctioneer, 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 for its object improvements in repairing slated roofs and in
means for the same.
It is now usual in repairing slated roofs and when a new slate is required to
replace one which bas fallen, to fasten this new slate in its place by strips of lead
passed beneath its lower edge and bent upwards; but experience proves that slates so
fastened are not securely held and besides the leaden strips are unsightly.
Now according to my invention I employ clips preferably of sheet copper and
of a T form. I take the slate which is to be inserted and notch its edges on each
side to receive the stem of such a clip whilst the head of the clip lies flat upon the
face of the slate.
The notches in the slate are formed somewhat higher up the slate than the ordinary
nail holes and in such a position that the stems of the clips when the slate is in its
place come immediately over one of the laths to which the slates are nailed. When
the clips have been inserted their stems rest flat upon the upper side of the lath and
so the new slate is securely held.
In order that my said invention may be fully understood and
effect 1 will proceed to describe the drawings hereunto annexed.

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 is a section of a portion of a roof which has been repaired in accordance
with my invention.
Figure 2 is a front view of a slate prepared to be inserted into a roof to replace a
slate which has fallen out from its place.
Figure 3 is an edge view of the slate shown by Figure 2 and in the same figure
also one of the metal clips to be used in fastening the slate is represented.
Figure 4 is similar to Figure 3 but shows the positions of the slate and clip when
in the roof and in relation to the slate lath which serves to support them.
In Figure 1a a are the rafters and bare state laths, cc are the ordinary slates of
a slate which has been lost.

preferably of sheet copper and are formed by doubling upon itself a strip of metal
about twice the length of the clip. The clips are casily formed in this way and are
more readily bent as required in use than if otherwise made. In repairing the roof
the upper edge of the new slate is inserted between the slates immediately above and
below the position of the lost slate and then the new slate is pushed up to the position
previously occupied by the lost slate. The clips e are inserted from the inside and
brought to rest upon their slate lath as seen in Figure 4. The stems of the clips
may then be bent as is seen in Figure 1 and the new slate is then secure.
When the edge of a slate comes over a rafter so as to interfere with the
insertion of the clip in this position, a hole is made in the slate instead of a notch,
the clip is inserted in the slate and is turned upwards, the slate then pushed up into
its place and the clip turned down above its lath.
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 :-
The method and means for repairing a slated roof as herein described.
