PROVISIONAL SPECIFICATION.
Improvements in Appliances for Preventing Bursting of Water
Pipes by Freezing.
I WILLIAM HENRY LE ROY of Lymington in the County of Hampshire,
Painter and Plumber do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to prevent freezing in pipes for conveying hot or
cold water. I empty the pipes conveying water from the main to the household or
other service by means of a bib-cock inserted at the outlet end of the valve
controlling the service from the main. To admit of placing the bib-cock for the
purpose aforesaid the outlet shank is made longer than those in ordinary use.
The draw-off bib-cock or tap may be fixed horizontally or in any convenient
manner or if a tap is not employed an orifice may be made in the shank of the
outlet valve, which, when the water is in the pipes is closed by a screw plug and
when the pipes are to be emptied the plug is removed.
Freezing and the bursting of pipes is thus prevented by drawing off all water
contained in the pipes beyond the valve controlling the supply from the main.
Dated this Tenth day of February 1896.

Improvements in Appliances for Preventing Bursting of Water
Pipes by Freezing.
I WILLIAM HENRY LE ROY of Lymington in the County of Hampshire,
Painter and 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 my invention is to prevent freezing in pipes for conveying hot or
cold water. I empty the pipes conveying water from the main to the household or
other service by means of a bibcock as shewn at Fig. 3 inserted at the outlet end
of the valve controlling the service from the main. To admit of placing the
bibcock for the purpose aforesaid the outlet shank of the union or tap shewn at
Figs. 1 and 2 is made longer than those in ordinary use. The draw-off bibcock or
tap Fig. 3. may be fixed horizontally or in any convenient manner, if a tap is not
employed an orifice as shewn at B Fig. 3. may be made in the shank of the outlet
valve which when the water is in the pipes is closed by a screw plug G Fig. 2.
and when the pipes are to be emptied the plug is removed. Freezing and the
bursting of pipes is thus prevented by drawing off all water contained in the pipes
beyond the valve controlling the supply from the main.

page_text: 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. A tap or union with elongated shank in which is fitted a bibcock or tap for
the purposes specified, as described and illustrated substantially and as set forth.
2. A tap or union with elongated shank fitted with orifice and screw plug for
the purposes specified substantially and as set forth.
Dated this 11th day of November 1896.
