Year: 1872

page_text: LETTERS PATENT to Philippe Rosier, of No. 82, Boulevard Sébastopol,
Paris, France, for the, Invention of "IMPROVEMENTS IN APPARATUS
FOR EMPTYING OR EXHAUSTING THE COMPUIT OR SUPPLY Pipes of Cisterns
AND SIMILAR STRUCTURES AS ▲ PROTECTION FROM FROST OR other Damage.”
Sealed the 10th October 1872, and dated the 19th April 1872.
PROVISIONAL SPECIFICATION left by the said Philippe Rosier at the
Office of the Commissioners of Patents, with his Petition, on the
19th April 1872.
I, PHILIPPE ROSIER, of No. 82, Boulevard Sébastopol, Paris, France,
5 do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN APPARATUS FOR EMPTYING OR EXHAUSTING THE CONDUIT OR SUPPLY Pipes of
CISTERNS AND SIMILAR STRUCTURES AS A PROTECTION FROM FROST OR OTHER
DAMAGE," to be as follows:-
This Invention is intended to preserve pipes from the effects of frost
) by keeping them empty when desired, and at the same time guarding

page_text: against any accident to them which might occur from the violence
of the shock produced by the force of the water when a check is put to
its progress.
The apparatus consists of a recipient placed either below or inside a
reservoir, or any suitable position, and is supplied with four apertures
communicating with pipes, whose object is as follows, and which may be
designated as B, C, D, E:-The first, B, is the supply pipe from a
reservoir; the second, C, admits the requisite air for working the
apparatus; the third, D, is the pipe from which the water is drawn off
for supplying the wants of the house; and the fourth, E, is the pipe for
emptying the main and other pipes when a sufficient supply has been
taken in. The recipient A is supplied at will and according to require-
ments by means of a valve F, consisting of a rundle of india-rubber
placed above the pipe B, and attached to a metal shaft G actuated by
means of a lever L, crank K, and second shaft T.
The shaft and valve are supported by a framework I arranged inside
the reservoir at the bottom. This valve when closed over the pipe B
prevents the water in the reservoir from communicating with the
recipient A and the pipes supplying the apartments.
The shock of the water occasioned by its sudden check is guarded.
against in the following manner :-The diameter of the supply pipe B
and that of the pipe D is calculated so that the former is less than the
latter, the result being that as soon as the service cock M is turned,
more escapes from the recipient than enters it at the time, so that a.
vacuum occurs at the upper part of the recipient, and when the cock
is closed all the shock that is felt results from the small quantity of
water contained in the receiver, and is so slight as to be nearly
imperceptible.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Philippe Rosier in the Great Seal Patent Office 30
on the 15th October 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, PHILIPPE
ROSIEB, of No. 82, Boulevard Sébastopol, Paris, France, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of April, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Philippe Rosier, Her special licence that
I, the said Philippe Rosier, my executors, administrators, and assigns,
or such others as I, the said Philippe Rosier, my executors, adminis-
trators, and assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the term therein
expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN APPARATUS
FOR EMPTYING OR EXHAUSTING THE CONDUIT OR SUPPLY PIPES OF CISTERNS AND
SIMILAR STRUCTURES AS A PROTECTION FROM FROST OR OTHER DAMAGE," upon the
condition (amongst others) that I, the said Philippe Rosier, my executors
or administrators, by an instrument in writing under my, or their, or one
of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of
the said Letters Patent.
NOW KNOW YE, that I, the said Philippe Rosier, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement and accompanying Drawings, that is to say:-
The object of this Invention is to protect pipes from bursting; the result
either of frost or the shock produced by an abrupt check to the progress
of the water when suddenly cut off. This may be effected in several ways,
the principle in all cases being identical, and the first of which consists
in the employment of a recipient A, placed either below or inside
a reservoir R, or in any suitable position; it is furnished with four
apertures communicating with a like number of pipes, whose object is
as follows, and which may be designated as B, C, D, E :-The first, B,
is the conduit or supply pipe from a reservoir R or other source; the
second, C, admits the requisite air for working the apparatus; the
third, D, is the service pipe from which the wants of the house are
supplied; and the fourth, E, is the pipe for emptying the main and

page_text: other pipes when a sufficient supply has been taken in GO meer
requirements.
Fig. 1 represents the apparatus or recepient A placed below a
reservoir R; it is filled at will by means of the valve F, consisting of a
small rundle of india-rubber placed above the supply pipe B and attached
to a metal shaft G, actuated by a lever L, crank K, and rod T.
The shaft and valve are supported by a frame I arranged inside and at
the bottom of the reservoir R; this valve when closed over the pipe B
cuts off the water in the reservoir R from the recipient A and the pipes
supplying the apartments. M is the service tap, and N the tap for
emptying the recipient A and pipes when the communication between
the reservoir R. and recipient A. has been cut off.
The shock of the water occasioned by its sudden check is guarded
against in the following manner :-The diameter of the supply pipe B
and that of the pipe D is calculated so that the former is less than the
latter, the result being that as soon as the service cock M is turned more
water leaves the recipient A than enters therein at the same time, so that
à vacuum occurs at the upper part of the recipient A, and when the
cock is closed the only shock that is felt is the result of the small
quantity of water contained in the recipient, and is so slight that it is
scarcely perceptible.
Fig. 2 represents the apparatus placed inside a reservoir R. The same
letters of reference indicate like parts in these two Figures.
The same principle is applicable to drinking fountains; in this case
the recipient A is placed in the wall where the fountain is established,
and is arranged above the service tap and in lieu of the reservoir; it
communicates by a conduit with the ordinary supply pipes.
Figs. 3, 5, and 7 are modifications on the above, but whose principle
is unchanged. Fig. 3 is a front view of the apparatus employed; Fig. 4
is a plan of the same; and Figs. 5 and 6 are sections thereof. It consists
of a glass cylinder A placed in a metal, support C having two openings,
one I for receiving the water for supplying the apparatus, and the
other K for receiving the service tap L, both screwing into the part C.
cap B hermetically closes the cylindrical tube A so that there is no
A

page_text: loss of liquid. A vacuum is produced with this apparatus the same as
previously described, a metal pipe D branching at e to an opening in the
support O, and corresponds with that of the supply pipe.
This tube
passes through the cap B and introduces itself into the cylinder or
recipient A; it is by this tube that the water enters the cylinder, and
by the air therein a counter pressure is produced at the upper surface of
the liquid
recipient A; it is by this tube that the water enters the cylinder, and
by the air therein a counter pressure is produced at the upper surface of
the liquid.
The vacuum occasioned is sufficient to prevent any shock when the
tap is acted on. The supply of air is naturally and easily effected, and
the supply of water may be produced differently and as desired.
a is the junction plate of the pipe and support O; e, e, are nut screws;
ff, are shafts supporting and uniting the cylinder and cap; G is a
screw junction connecting the supply pipe to the support C; J is a
screw junction receiving the service tap L and connecting it with the
support C.
Fig. 7 is a similar apparatus, differing from the last-named only in
the manner of supplying air. It consists of a glass cylinder A, which
may be a truncated cone or any suitable form; the upper part has a
cap B bearing in the centre a small circular opening for the admission of
air N, and in which a float moves composed of a metal shaft o, bearing a
rundle of india-rubber n surmounting the float M in cork. A regulator R
is attached to the support C, or to the screw junction admitting the
water for regulating its introduction into the recipient A.
As soon
as the water enters and has reached the float, the water increasing in
volume raises the rundle of india-rubber and hermetically closes the air
opening N.

the purposes herein set forth.
In witness whereof, I, the said Philippe Rosier, have hereunto
set my hand and seal, this Eighth day of October, in the year
of our Lord One thousand eight hundred and seventy-two.
