PROVISIONAL SPECIFICATION.
Pipe Subway.
1, SAMUEL SPRATT 80 Wakehurst Road Clapham Common in the County of
Surrey Carpenter and Joiner and FREDERICK BAILEY of 20 Bellendon Road
Peckham in the County of Surrey Grocer do hereby declare the nature of this
invention to be as follows:-
:-
A pipe subway for footpaths for the purpose of storage for pipes under footpaths
or highway's and for a ready and more convenient way of storage of pipes and
electric wires hereinafter described and in this description I shall include all such
novelty in the fittings and details of such pipe subway as I wish to include in my
invention.
Inasmuch as in fitting up of my said pipe subway it is necessary that great care
should be observed I have invented and shall hereinafter describe the mode of so
fitting the pipe subway ready for work and the apparatus which I have invented
for this purpose.
And first as to the pipe subway.
This subway has been designed by the inventor to be manufactured in sheet or
cast iron as circumstances may require.
And I claim that it will give the London County Council Fire Brigade access
to the gas pipes without breaking the footpaths in case of fire.
The subway consists of two or more sections in lengths varying according to the
nature of, or width of the path. It consists of two or more iron troughs with
removable covers.
As to the access to the same.
This portion of my invention consists of an iron frame and iron tray which said
frame is built up level with the footpath, and supported by suitable brickwork, the
iron tray is so constructed as to receive stone, cement, or asphalte paving as may be
required.
The said, tray, and frame are double rebated so as to affoard additional
strength.
As to the pipes.
I claim that in case of repairs it will facilitate the removal of pipes without
disturbing or destroying the footpaths and should it be necessary to add one or
more pipes in the subway after it is fixed it will not be necessary to disturbe or
remove the footpath; to facilitate the removal of the pipes it must be understood
that it is necessary and designed by ine that the said pipes should be fitted together
by union joints or by back nuts so as to unscrew in the manhole next to and
adjoining the tap that is on the consumers side of the tap I do not claim for these
joints.
As to the cover.
This cover is designed to be removed so as to form two independant parts, and I
claim for this. It is fitted as follows two screws are fitted on each side forming in
themselves a projection these are not screwed tight down, but are set at a distance
equal to the thickness of the flange of the trough forming the lower portion of the
pipe subway, at a distance that will permit of sliding them along in the slot
provided for them in the flange or projection of the trough which said projection
hangs over the outsides of the trough.
As to the trough.
I claim for this in its being seperate from the cover I can apply it to existing

page_text: pipes which need not be removed to be placed in the pipe subway. This pipe
subway having a removable cover can be applied as follows:
As to the fixing of the pipe subway where there are existing pipes.
Having removed the cover and excavated the earth, turn the trough on the side
passing one side under the existing pipes then gradualy turn the upperside or mouth
of the trough upwards, afterwards placing on the cover, which said cover gives the
pipes permanent protection.

covers.
As to the access to the same.
This portion of our invention consists of an iron frame and iron tray which said
frame is built up level with the footpath and is supported by suitable brickwork,
the iron tray is so constructed as to receive stone, cement, or asphalte paving as
may be required.
The said tray and frame are double rebated so as to afford additional strength.
As to the pipes.
We claim that in case of repairs it will facilitate the removal of pipes without
disturbing or destroying the footpaths and should it be necessary to add one or
more pipes in the subway after it is fixed it will not be necessary to disturbe or
remove the footpaths to facilitate the removal of these pipes it must be understood
that it is necessary and designed by us that the said pipes should be fitted together

page_text: by union joints or by back nut so as to unscrew in the manhole next to and
adjoining the tap that is on the consumers side of the tap We do not claim for
these joints.
As to the cover.
This cover is designed to be removed so as to form two independant parts, and
we claim for this. It is fitted as follows two screws are fitted on each side forming
in themselves a projection, these are not screwed right down but are set at a
distance equal to the thickness of the flange of the trough forming the lower
portion of the pipe subway at a distance that will permit of sliding them along in
the slot provided for them in the flange or projection of the trough which said
projection hangs over the outsides of the trough.
As to the trough.
We claim for this in its being seperate from the cover we can apply it to existing
pipes which need not be removed to be placed in the pipe subway this pipe subway
having a removable cover can be applied as follows:
As to the fixing of the pipe subway where there are existing pipes.
Having removed the cover and excavated the earth, turn the trough on the side
passing one side under the existing pipes then gradualy turn the upperside or mouth
of the trough upwards afterwards placing on the cover which said cover gives the
pipes permanent protection.
As to the drawing's left with Provisional Specification.

Fig. 2 shows section of one end of pipe subway (empty).
Fig. 3 shows section of one end in use or fitted with pipes and wire.
Fig. 4 enlarged section of one corner of the cover and frame.
Fig. 5 shows enlarged perspective of the trough or lower portion of the pipe
subway showing slots in flanges.
Fig. 6 plan of manhole with pipes and taps in manhole.
Having now particularly described and 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
1st. The frame and cover being double rebated.
2ndly. The cover of the subway being seperate Fig. 5 slots in flanges and arched
cover Fig. 2.
