Year: 1872

page_text: LETTERS PATENT to Jules Louis Adam, of Wandsworth Road, in the
County of Surrey, for the Invention of “ An Improved TAP POR DRAWING
OFF LIQUIDS."
Sealed the 28th March 1873, and dated the 30th September 1872.

PROVISIONAL SPECIFICATION left by the said Jules Louis Adam at
the Office of the Commissioners of Patents, with his Petition, on the
30th September 1872.
I, JULES LOUIS ADAM, of Wandsworth Road, in the County of
Surrey, do hereby declare the nature of the said Invention for "An
IMPROVED TAP FOR DRAWING OFF Liquis,” to be as follows:-
My improved tap consists essentially of an upper passage formed in
the body of the tap, and of a lower passage formed in a piece sliding to
and fro in a lug or boss on the body of the tap in such wise that the
two passages may form one continuous tube, or their connection be cut
off at pleasure by the movement of the sliding piece.
Figure 1 is a side elevation of a tap embodying my Invention, and
Figure 2 a front view of same.

page_text: A is the body of the tap having a passage a, and on the under side a
lug or boss B which is bored so as to receive the slide or outlet pipe C.
C is the slide or outlet through which is the passage 6; D, D', are two
collars or flanges so arranged as to allow of the slide being drawn
sufficiently forward to bring the passages a and b into connection with
cach other and form a continuous conduit; E, spiral spring; c is a set
screw which enters the slot d and thus prevents the slide O from turning
during its forward or backward motion; it may also be used in lieu of
the collars D, D', to regulate the to-and-fro movement of the sliding
piece O when the spring E is not used.
To draw off the liquor from the cask pull forward the outlet pipe or
spout C until stopped by the collar D', the liquid will then flow through
a, b, into the jug, bottle, or other recipient; when this is filled let go
the pipe C, which the spring E will then drive back breaking the con-
nection between the two passages and thereby stopping the flow of the 1
liquid.
For bottling taps I dispense with the spiral spring E, and simply push
the pipe C backward to arrest the flow of the liquid; a closing spring
will however be found desirable in taps for domestic use, as the tap
cannot then carelessly be left open and the liquid be wasted.
My improved tap will greatly economize time in bottling.
The sliding piece C may be locked to the body of the tap if desired
to preserve the contents of the cask or other vessel from being
surreptitiously drawn off..
In conclusion I would observe that the accompanying Drawing is 2
merely illustrative of my Invention, and that I do not limit myself to
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Jules Louis Adam in the Great Seal Patent Office 30
on the 29th March 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JULES
LOUIS ADAM, of Wandsworth Road, in the County of Surrey, send
greeting.

Letters Patent, bearing date the Thirtieth day of September, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors,
3 give and grant unto me, the said Jules Louis Adam, Her special
licence that I, the said Jules Louis Adam, my executors, adminis-
trators, and assigns, or such others as I, the said Jules Louis Adam,
my executors, administrators, and assigns, should at any time agrée 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 Islo of Man, an Invention for "An Improved
TAP FOR DRAWING OFF LIQUIDS," upon the condition (amongst others) that
I, the said Jules Louis Adam, 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 Jules Louis Adam, 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:-
.
My improved tap consists essentially of an upper passage formed in
the body of the tap, and of a lower passage formed in a piece sliding to
and fro in a lug or boss on the body of the tap in such wise that the two
passages may form one continuous tube, or their connection be cut off
at pleasure by the movement of the sliding piece.
On the accompanying Sheet of Drawing, Figure 1 is a side elevation
of a tap embodying my Invention, and Figure 2 a front view of
same.
A is the body of the tap having a passage a, and on the under side a
lug or boss B, which is bored so as to receive the slide or outlet pipe C;
O is the slide or outlet through which is the passage b; D, D', are two
collars or flanges so arranged as to allow of the slide being drawn
sufficiently forward to bring the passages a and b into connection with
each other, and form a continuous conduit; E, spiral spring; c is a set

page_text: This tap is particularly adapted for bars of public-houses, hotels, and
refreshments rooms, the tap being opened by the glass itself and-closing
automatically.
My improved tap may be made of any suitable metal or material.
Having now described and ascertained the nature of my said Inven-
tion and in what manner the same is or may be performed, I would
have it understood that the accompanying Drawings are merely illus.
trative of my Invention and that I do not limit myself to the shape or
precise details therein shown, nor confine myself to any particular
dimensions of parts; for example, the lower passage may be formed in
a tube or plate of any shape or size and be moved to and fro in any
direction by means of any kind of spout, lever, or lug, and the outlet
be closed automatically or otherwise, and other modifications be made
while retaining the essential feature of my Invention, and I claim as
secured to me by the hercin-before in part recited Letters Patent the
use of a tap combining an upper passage formed in the body of the
tap and a lower passage formed in a sliding piece applied thereto in
such wise that the two passages may form one continuous tube or
their connection be cut off at pleasure by the movement of the sliding
piece.
In witness whereof, I, the said Jules Louis Adam, have hereunto
