I THOMAS FREDERICK LUTHER, of 21, Rodney Terrace Lower Richmond
Road, Putney, Surrey Plumber, do hereby declare the nature of this invention to
be as follows:-
My invention relates to a combined stop-cock and draw-off tap for water supply
pipes, and has for its object, more particularly, to prevent the pipes in the house
from bursting during frosty weather, while it may be further used to draw the
water direct from the main when the said pipes are frozen.
According to my invention, the stop-cock, (which is of the usual construction
and which is generally situated in the lower part of the house and therefore not
liable to become frozen) is furnished upon the outlet side, or side to which the
cistern supply pipe is attached, with a small outlet pipe or draw-off tap which is
closed by a fly nut, so that in frosty weather it is only necessary to turn off the.
stop-cock and open the draw-off or outlet tap when the house pipes will be quickly
emptied, thus preventing them from becoming frozen and consequently from
bursting; the water being of course turned on for a short time during the day
to fill the cistern and again turned off and the house pipes emptied which is
particularly necessary during the night, as the water being then quite still, is very
liable to freeze; or should the house pipes have become frozen and therefore no
water able to enter the cistern, the stop-cock can be opened slightly as also the
draw-off or outlet thereby enabling the water to be drawn direct from the main.

THOMAS FREDERICK LUTHER of 15 High Street Putney in the County of
Surrey Plumber late of 21 Rodney Terrace Lower Richmond Road Putney,
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:-
My invention relates to a combined stop-cock and draw-off tap for water supply
pipes, and has for its object, more particularly to prevent the pipes in the house from
bursting during frosty weather while it may further be used to draw the water
direct from the main should the said pipes in the house be frozen.
According to my invention the stop-cock (which is of the usual construction and
which is generally situated in the lower part of the house and therefore not liable
to become frozen) is furnished upon the outlet side, or middle of the stop-cock
above the jumper with a small outlet pipe marked C in drawing on Sheet 2 and
Point I

page_text: screwed to receive a fly nut cap as marked C on drawing on Sheet 1, so that in
frosty weather it is only necessary to turn off the stop-cock and open the fly nut C
when the pipes leading to the cistern will be quickly emptied thus preventing them
from becoming frozen and consequently from bursting, the water being of course
turned on for a short time during the day to fill the cistern and again turned off
and the house pipes emptied, which is particularly necessary during the night as
the water being then quite still, is very liable to freeze; or should the house pipes
have become frozen and no water able to be drawn from the cistern the stop cock
can be slightly opened as also the fly nut cap marked C on drawing on Sheet 1
thereby enabling the water to be drawn direct from the water company's
main pipe.
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
The small outlet pipe marked C on drawing on Sheet 2 cast into the middle of
the stop cock above the inlet D on drawing on Sheet 2 so as to control the water
by the screw-down valve the same as in an ordinary draw off cock when being
used as the same after fly nut cap C being removed.
Dated this 8th day of October 1894.
