Improved Means for Repairing Slated Roofs.
ERNEST ALBERT SMITH 66 Upper Grosvenor Road Tunbridge Wells Kent
Builder do hereby declare the nature of this invention to be as follows :-
A. is a flat headed screw. B. is a lead washer or collar which shuts tight on
slate when screw A. is turned by screwdriver which compresses the slate between
lead collar B. and metal plate C. which rests upon the top of slate batten or
boards of roof and is secured by a nail at point E. The leg D rests against
the upper edge of slate batten or in a hole made in boards of roof "if a boarded
roof" between the longitudinal joint of under course of slates and thus fastening
cannot slip whatever angle the roof may be.
To fix the new slate a hole is punched in same and slate is inserted under
upper course of slates, then male screw A. is turned through hole in slate and
screwed down tight into female screw in plate C. compressing slate between water-
tight collar B. and metal plate C. which is first fixed to batten or boards
of roof.
The plate C is of sufficient length and flexibility to allow for lifting of slate
during expansion by frost.
The title of my invention is An improved means for repairing slated roofs.

ERNEST ALBERT SMITH 66 Upper Grosvenor Road Tunbridge Wells Builder
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, reference being made to the drawings filed with my Provisional
Specification:-
:-
A is a flat headed screw. B. is a washer or collar of lead or other material
which shuts tight on the surface of a slate when screw A. is turned down by a
screwdriver, compressing the said slate between the collar B and the metal
plate C., a hole having first been made in the said slate to receive the screw A.
To fix a new slate by my invention first place metal plate C. (with leg D. to
rest against the upper edge of slate batten) between the longitudinal joint of the
under-course slates of roof to be repaired, and in the case of a boarded roof make
a hole to receive the leg D. (if leg be made on the particular plate C.). Then
nail plate C. into the batten or boards of roof through nail-hole at point E.
Then make a hole in the said new slate at a point to correspond with female
screw in plate C. Then push the said new slate to be fixed, up to its proper
position and insert screw A. through the collar or washer B. and through the said
7071

page_text: hole in the said new slate into the under metal plate C. Then screw down the
screw A tightly, thus rendering the hole made in the said new slate water-
tight.
The plate C. may be made with or without the leg D.
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 :-
1. An improved means for repairing slated roofs, without the removal of the
upper course of slates.
2. That my above invention shall consist of a screw with a flat head, a washer
or collar, and a metal plate with or without leg to rest against slate batten.
3. That any metals or other materials may be used in the construction of the
said invention.
