PROVISIONAL SPECIFICATION.
Improved Appliance for Repairing Burst or Broken Pipes.
We, JOHN CHARLES SPRAGG of Eyet Street Leigh in the County of
Lancaster, Plumber and WILLIAM HENRY BOWLER of Sandileigh Withington,
in the said county Architect and Surveyor do hereby declare the nature of the
said invention to be as follows:-
The invention is designed to provide a temporary appliance for repairing lead
or other pipes such as water or gas pipes which accidentally become burst or
broken through freezing or other causes.
It consists essentially of a thin flexible plate of metal rubber or the like
covered or lined on one side with a sheet of rubber or other suitable packing
provided with one two or more small hooks along one edge and two or more
lugs or projections along the other edge to which a chain or band of suitable
shape is attached with a screw or other tightening device at one end.
In carrying out the invention we provide a thin plate of brass lead or other
suitable metal or material and to one side of this we attach a sheet of rubber
or other material capable of making a watertight joint. On the lower edge of
the plate we attach or form one two or more small hooks preferably two one
at each corner and at the upper edge we provide two projecting lugs or shoulders
to receive a tightening screw. A chain or band of any suitable material is
formed with eyes to engage with the hooks on one edge of the plate and a
tightening screw or similar device to engage with the lugs at the other edge.
We apply the side of the plate carrying the packing to the broken part of
the pipe and draw the chain or band round the other side until the tightening
screw engages with the lugs. The nut is then screwed up tight to bring the
appliance into position and hold it securely.

Improved Appliance for Repairing Burst or Broken Pipes.
We, JOHN CHARLES SPRAGG, of Eyet Street, Leigh, in the County of
Lancaster, Plumber, and WILLIAM HENRY BOWLER, of Sandileigh, Withington,
in the said county, Architect and Surveyor, 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:-
The invention is designed to provide a temporary appliance for repairing lead or
other pipes such as water or gas pipes which accidentally become burst or broken
through freezing or other causes.
It consists essentially of a thin flexible plate of metal rubber or the like covered

page_text: or lined on one side with a sheet of rubber or other suitable packing
a screw or other suitable tightening or clamping device whereby it can be tightly
clamped around the pipe over a fracture or hole.
It will be fully described with reference to the accompanying drawings in which
as illustrations four forms or developments of the invention are shown.

Fig. 13. Side elevation of same.
Upon one side of a thin flexible plate A of brass lead or other suitable metal or
material we attach a sheet or pad B of rubber or other material capable of making
a watertight or airtight joint. To this we affix or attach a screw C or other
tightening or clamping device whereby the sheet or pad B may be drawn tightly
over or around a pipe D at any position around its length.
Referring to Figs. 1, 2, and 3 we provide a plate A of thin flexible sheet brass
covered with a pad B of rubber on the inner side. On the lower edge we form a
hook or lugs a and at the upper edge a projecting lug or shoulder b. To these we
connect a chain or band E of any suitable shape with a tightening screw Cattached
at one end. One end of the chain E engages with the hook or lugs a and a out F
on the screw engages with the lug or shoulder 6 the pad B is placed upon the pipe
over the hole or fracture and the chain E passed round it the nut is then screwed
down upon the lugs and the pad drawn tightly against the pipe D to close the
fracture.
Referring to Figs. 4, 5 and 6 we provide a plate A of thin flexible brass or
other metal long enough to encircle the pipe D and at or near the centre of this
plate we cement the pad B. The plate A is provided with a number of holes a at
one or both ends to adapt it to pipes of different diameters. Through the holes a
we pass a clamping or tightening screw C with washers c and c¹ at one side of the
plate the screw passes through one washer and is screwed into the other so that by
screwing up the screw C the plate is tightly clamped around the pipe D. The
washers are preferably shaped as shown.
Referring to Figs. 7 and 8 a similar device is shown with an ordinary screw C
and nut C¹ to tighten or clamp the plate A in position.
Instead of the plates shown in Figs. 6 and 11 a band or chain to embrace the
pad may be employed.
Referring to Figs. 12 and 13 a plate A. of thin metal with a pad of rubber B is
held in position upon the pipe D by a chain E passed round it and around the pipe
and clamped in position by the screw C and nut F. The free end of the chain
engages with lugs a upon a washer or collar d through which the screw C passes.
Referring to Figs. 9 10 and 11 a similar plate A is shown with pad B. To one
end of the plate is attached a screwed sleeve or washer C" projecting out at one
side thereof. At the other end of the plate is cut one two or more holes a which
fit over the projecting part of the sleeve C the plate A being long enough to
overlap around the pipe D as shown in Fig. 10. The screw C is screwed into the
sleeve C and the plate A. and pad B are tightened in position upon the pipe D by
the end of the screw bearing against the surface of the pipe.
In another modification one or two loose clips with screws may be passed around
the plate A and pad B.

page_text: Having now particularly described and ascertained the nature of the said inven- .
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. An appliance for repairing burst or fractured pipes constructed of a thin.
flexible plate of metal or other suitable material with a pad or lining on one
side of rubber or other packing material and a tightening screw or clamping
device to secure the appliance in any position upon the pipe substantially as.
described.
2. An improved appliance for repairing burst or fractured pipes constructed
substantially as described and shown with reference either to Figs. 1-3, Figs. 4-6,..
Figs. 7 & 8 Figs. 9-11 or Figs. 12 and 13 of the accompanying drawings.
