FROVISIONAL SPECIFICATION left by the said Robert Warner and
John Brooke at the Office of the Commissioners of Patents, with
their Petition, on the 21st July 1871.
We, ROBERT WARNER, of Jewin Crescent, in the City of London,
Brass Founder, and JOHN BROOKE, of the same Place, Foreman En-
gineer, do hereby declare the nature of the said Invention for "Im-
PROVEMENTS IN PUMPS," to be as follows:-
-:
This Invention has for its object improvements in pumps.
In order to attach the leaden suction pipe of a pump without a
soldered joint we employ a socket, which is bolted down to a suitable
foundation. The socket is shaped so as to receive the foot of the pump
barrel, and it also has a conical hole or passage at the bottom to receive
the suction pipe. The leaden suction pipe is similarly coned at the end,

page_text: and it is passed through the hole or passage in the socket until the
cone on the pipe bears against the sides of the internal cone of the
socket. Within the pipe again another conc is placed, it has a flat
flange around its upper edge. The foot of the pump cylinder bears on
this flange, a packing being interposed to render the joint air tight.
This flange also forms the seating of the suction valve, and the leather
of the valve forms the packing. The bolts which bind the foot of the
pump cylinder down into the socket cause the coned end of the suction
pipe to become nipped, and the pipe moulds itself to the holding surfaces
so as to form a perfectly air-tight joint. As a further security, an elastic
washer may be inserted under the flange of the inner cone to bear
against the upper end of the leaden pipe and the interior of the socket.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Robert Warner and John Brooke in the Great
Seal Patent Office on the 19th January 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, wc, ROBERT
WARNER, of Jewin Crescent, in the City of London, Brass Founder, and
JOHN BROOKE, of the same Place, Foreman Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first day of July, in the year
of our Lord One thousand eight hundred and seventy-one, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Robert Warner and John Brooke, Her
special license that we, the said Robert Warner and John Brooke, our
executors, administrators, and assigns, or such others as we, the said
Robert Warner and John Brooke, our executors, administrators, 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 PUMPS," upon the con-
dition (amongst others) that we, the said Robert Warner and John
Brooke, our executors or administrators, by an instrument in writing
under our or their hands and seals, or under the hand and seal of one of
us or them, should particularly describe and ascertain the nature of the

page_text: 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 Robert Warner, on behalf of
myself and the said John Brooke, do hereby declare the nature of the
said Invention, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement
thereof, that is to say :-
This Invention has for its object improvements in pumps.
In order to attach the leaden suction pipe of a pump without a
soldered joint we employ a socket, which is bolted down to a suitable
foundation. The socket is shaped so as to receive the foot of the pump
barrel, and it also has a conical hole or passage at the bottom to receive
the suction pipe. The leaden suction pipe is similarly coned at the end,
and it is passed through the hole or passage in the socket until the cone
on the pipe bears against the sides of the internal cone of the socket.
Within the pipe again another cone is placed, it has a flat flange around
its upper edge. The foot of the pump cylinder bears on this flange, a
packing being interposed to render the joint air-tight. This flange
also forms the seating of the suction valve, and the leather of the valve
forms the packing. The bolts which bind the foot of the pump cylinder
down into the socket cause the coned end of the suction pipe to become
nipped, and the pipe moulds itself to the holding surfaces so as to form
a perfectly air-tight joint. As a further security an elastic washer may
be inserted under the flange of the inner cone to bear against the upper
end of the leaden pipe and the interior of the socket.
In order that our said Invention may be most fully understood and
readily carried into effect, we will proceed to describe the Drawings
hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side view, and Figure 2 a vertical section of a portion of
a pump. Those parts only are shewn which are affected by our In-
vention, the other parts may be of ordinary construction.

page_text: c is
having been expanded to fit the socket by driving a plug into it.
a flanged cone into which enters the leaden pipe, and when this cone is
pressed down by screwing up the bolts the suction pipe becomes nipped
between the exterior of the cone and the inside of the socket. In this
way an air-tight joint is made, but for further security a vulcanised
india-rubber washer d (shewn separately at Figure 3) may be inserted
under the flange of the cone, e is the clack or valve, its leather (which
is shewn separately at Figure 4) is laid upon the flange of the cone c,
and the foot of the pump barrel f stands upon it. 9, 9, are screw bolts
and nuts, the bolts pass through lugs on the barrel and through the
socket piece a, thus nipping the leather of the clack or valve e, and
forming an air-tight joint at the foot of the pump barrel.
Sometimes in place of the clack or valve e we employ a metallic
valve or a flexible ring valve, but in either case the valve seat is formed
upon the flange of the cone c, as in the arrangement which the Drawing
shews.
Having thus described the nature of our said Invention, and the
manner of performing the same, we would have it understood that we
claim the construction of pumps substantially as described.
In witness whereof, the said Robert Warner have hereunto set
his hand and seal, this Nineteenth day of January, in the year
of our Lord One thousand eight hundred and seventy-two.
