PROVISIONAL SPECIFICATION.
Improved Device for Checking Leakage of Water, Gas, Steam, and
the like from Pipes.
I, JOHN MAY, The Bottle House Penshurst Kent, Plumber, do hereby declare
the nature of this invention to be as follows:-
:-
The object of this invention is to provide a ready means of checking leakage
from pipes.
To carry out this invention I provide a hinged U shaped piece which receives
the leaking pipe. Fitting into this U shaped piece & over the pipe at the point
of leakage is another U shaped piece which is pressed down upon the break or
leak in the pipe by means of a screw or screws screwing into a bar the ends of
which rest in slots provided at each side of one of the U shaped pieces.
If desired the top of one of the U shaped pieces is recessed so as to receive the
pressure screw more conveniently.
If desired I may employ a flexible sheet or strip of rubber or such like elastic
material provided at its edges with metal. This serves the purpose of one of the
metal U shaped pieces, as it can be turned up, round the pipe, slots being provided
in the metal strips thereof to receive the ends of the bar aforesaid.
Dated this 24th day of December 1892.

COMPLETE SPECIFICATION.
Improved Device for Checking Leakage of Water, Gas, Steam, and
the like from Pipes.
1, JOHN MAY The Bottle House Penshurst Kent Plumber, 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 object of this invention is to provide a ready means of checking leakage
from pipes. To carry out this invention I provide a hinged U shaped piece which
receives the leaking pipe. Fitting into this U shaped piece and over the pipe at
the point of leakage is another U shaped piece which is pressed down upon the
break or leak in the pipe by means of a screw or screws screwing into a bar the
ends of which rest in slots provided at each side of one of the Ushaped pieces.
If desired the top of one of the U shaped pieces is recessed so as to receive the
pressure screw more conveniently. If desired I may employ a flexible sheet
or strip of rubber or such like elastic material provided at its edges with
metal. This serves the purpose of one of the metal U shaped pieces as it can be
turned up round the pipe, slots being provided in the metal strips thereof to
receive the ends of the bar aforesaid. In order that my invention may be fully
understood I now refer to the annexed drawings in which :-
Figure 1, is a plan view of my invention in position.
Figure 2, cross section through line -y in Figure 1.
Figures 3, 4 & 5, views of modified shapes of my invention for use on bends or
angles of pipes.
Figure 6, plan of a modified arrangement of flexible strip.
Figure 7, cross section of modified arrangement in position.
Figure 8. cross section through a modified form of my invention for use in the

page_text: Referring to Figures 1 & 2, a is the U shaped piece having slots for receiving
the ends of the cross bar b. e is a screw pin passing through the bar band bearing
against the second or inner U.shaped pieced having the strengthening piece or
ribe & recess f. The U shaped piece a is hinged at g. h is a piece of rubber,
canvas or such suitable material surrounding the pipe. It will be-seen that by
tightening the screw pin c against the piece d, the packing will be forced against
the pipe thus stopping the leak in the pipe i, which, for example may be at the
point or k. In the case of glass or very smooth pipes a thin metal lining may be
placed around the packing h
Referring to Figures 3, 4 & 5. These shapes are applicable where the leak occurs
at a bend or angle in a pipe, either at the side, inside or outside of the bend, the
operation & working of the parts being similar to that described in Figure 1.
Referring to Figures 6 & 7. In this case the strip of flexible material such as
canvas, rubber or like material is secured to the metal pieces m, having slots or
holes n-for-receiving the ends of the bar b. This strip & pièces m are used when
desired instead of the U shaped piece a.
Referring to Figure 8. In this case the pieces a', & d' are shaped as shown
so that in the case of two pipes lying close together a leak in one or both pipes
may be readily stopped or checked. In some cases I find it convenient to dispense
with the pieced and employ a screw having a loose washer which bears against
the pipe, in conjunction with the U shaped piece, a or flexible strip ; with or
without packing.
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 :-
1. The devices for stopping leakage in pipes substantially as described and
shown in Figures 1 to 8.
2. The improved device for stopping leakage in pipes, consisting of a hinged
U shaped piece having slots for engaging on the ends of a cross bar through which
a screw pin passes; an inner U shaped piece having a recess or notch in which
the end of the said screw pin engages, with or without packing substantially as
described.
3. The improved device for stopping leakage in pipes, consisting of a flexible
strip of material such as canvas, rubber or the like attached to two pieces of metal
having slots which engage on the end of a cross bar through which a screw pin
passes, an inner U shaped piece having a recess or notch in which the end of the
said screw pin eugages, with or without packing substantially as described.
4. The improved device for stopping leakage in pipes consisting of a U shaped
piece, having slots for engaging on the ends of a cross bar through which a screw
pin passes; an inner U shaped piece having a recess or notch in which the end of
the said screw pin engages, said U shaped pieces being grooved or shaped on their
inner surfaces for the reception of two or more pipes; with or without packing
substantially as described.
