Year: 1871

page_text: LETTERS PATENT to Emile Watteen, of the Royal Exchange, Middles-
boro’-on-Tees, in the County of York, for the Invention of "Improve-
MENTS IN STUFFING BOXES WITH METALLIC PACKING."-A communication
from abroad by Victor Duterne, of No. 111, Boulevard de Vaugirard,
Paris, in the Empire of France.
Sealed the 22nd May 1872, and dated the 23rd November 1871.
PROVISIONAL SPECIFICATION left by the said Emile Watteeu at the
Office of the Commissioners of Patents, with his Petition, on the
23rd November 1871.
I, EMILE WATTEEU, of the Royal Exchange, Middlesboro'-on-Tees,
in the County of York, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN STUFFING BOXES WITH METALLIC PACKING,"
to be as follows:-
This Invention has reference to an improved construction of stuffing
boxes with metallic packing for which Letters Patent were granted to

page_text: my foreign correspondent on the 7th June, 1865, No. 1555. In the
Specification to the said Patent was described a stuffing box containing
a solid metallic packing of antifriction metal, of a bi-conical form,
divided longitudinally into two parts and fitting round the piston rod or
other rod passing through the stuffing box, which metallic packing was
partially enclosed by two glands fitted over each end thereof, but so as
to leave an uncovered portion of the packing between the two glands.
Now one of the present improvements consists in constructing the
said glands so that they shall overlap each other and thus entirely
enclose the packing, in order to prevent the spreading out of the
uncovered portion thereof, which was apt to take place in the previous
arrangement.
Another improvement consists in the employment of variously modi-
fied forms and arrangement of the metallic packing differing from the
form and arrangement described in the aforesaid Specification, that is to
say, according to one modification two or more separate flat bi-conical
lengths of packing split in oblique directions are introduced into the
stuffing box one above the other with small spaces intervening between
them, and the annular angular spaces between the conical surfaces are
filled in with correspondingly angular rings of india-rubber.
According to another modification the metallic packing is built up of
a number of separate split rings of antifriction metal either entirely of a
cylindrical form, or the top and bottom rings are made of a conical form,
and india-rubber rings are introduced into the stuffing box so as to
surround either the entire metallic packing or only the upper and lower
conical end rings thereof.
According to another modification the metallic packing is made of a
spherical form split obliquely, and is wholly or partially enclosed.
between two glands of a corresponding hollow spherical form, the upper
gland being pressed down by screws, while the lower gland is pressed
upward by an annular spring of india-rubber or steel.
According to another modification, principally applicable to the
stuffing boxes of shafts for screw propellers, the inner part of the
metallic packing is formed conical, while the outer part is formed cylin-
drical, the last-named part being made to project beyond the stuffing a

page_text: box where it is formed with a circular shoulder to receive a metal ring,
through which the screws for screwing up the packing pass. The
packing is formed with projecting ribs or feathers which fit into corre-
sponding grooves in the stuffing box so as to prevent the packing from
rotating; the conical part of the packing is surrounded by a ring or
sleeve of india-rubber so as to form a water-tight joint against the side
of the stuffing box.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Emile Watteeu in the Great Seal Patent Office on
the 23rd May 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EMILE
WATTEEU, of the Royal Exchange, Middlesboro'-on-Tees, in the County
of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of November, 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 me, the said Emile Watteeu, Her special licence that
I, the said Emile Watteeu, my executors, administrators, and assigns, or
such others as I, the said Emile Watteeu, my 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 STUFFING BOXES
WITH METALLIC PACKING," (a communication to me from abroad by Victor
Duterne; of No. 111, Boulevard de Vaugirard, Paris, in the Empire of
France), upon the condition (amongst others) that I, the said Emile
Watteeu, 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.

page_text: NOW KNOW YE, that I, the said Emile Watteeu, 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, reference being had to the Drawings hereunto
annexed, and to the figures and letters marked thereon, (that is to
the nature of the said Invention, and in what manner the same is to De
performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Drawings hereunto
annexed, and to the figures and letters marked thereon, (that is to
say):
This Invention has reference to an improved construction of stuffing
boxes with metallic packing, for which Letters Patent were granted to
my foreign correspondent on the 7th June, 1865, No. 1555. In the
Specification to the said Patent was described a stuffing box containing
a solid metallic packing of antifriction metal of a bi-conical form,
divided longitudinally into two parts and fitting round the piston rod or.
other rod passing through the stuffing box, which metallic packing was
partially enclosed by two glands fitted over each end thereof, but so as
to leave an uncovered portion of the packing between the two glands.
Now one of the present improvements consists in constructing the
said glands so that they shall overlap each other and thus entirely
enclose the packing, in order to prevent the spreading out of the
uncovered portion thereof, which was apt to take place in the previous
arrangement.
Another improvement consists in the employment of variously modi-
fied forms and arrangements of the metallic packing, differing from the
form and arrangement described in the aforesaid Specification, that is to
say, according to one modification, two or more separate flat bi-conical
lengths of packing split in oblique directions are introduced into the
stuffing box, one above the other, with small spaces intervening between
them, and the annular angular spaces between the conical surfaces are
filled in with correspondingly angular rings of india-rubber.
According to another modification the metallic packing is built up of
a number of separate split rings of antifriction metal, either entirely of
a cylindrical form or the top and bottom rings are made of a conical
form, and india-rubber rings are introduced into the stuffing box so as to
surround either the entire metallic packing or only the upper and lower
.conical end rings thereof.

spherical form, split obliquely, and is wholly or partially enclosed
between two glands of a corresponding hollow spherical form, the upper
gland being pressed down by screws, while the lower gland is pressed
upward by an annular spring of india-rubber or steel.
According to another modification, principally applicable to the
stuffing boxes of shafts for screw propellers, the inner part of the metallic
packing is formed conical, while the outer part is formed cylindrical, the
last-named part being made to project beyond the stuffing box where it
is formed with a circular shoulder to receive a metal ring, through
which the screws for screwing up the packing pass. The packing is
formed with projecting ribs or feathers, which fit into corresponding
grooves in the stuffing box so as to prevent the packing from rotating;
the conical part of the packing is surrounded by a ring or sleeve of
india-rubber, so as to form a water-tight joint against the side of the

page_text: In the section, Fig. 6, Sheet II., the packing consists of several coned
pieces A, divided as shewn in the plan, Fig. 7, Sheet II.
In the section, Fig. 8, Sheet II., there is a conical packing ring A at
top and bottom resting on caoutchouc seatings B, B, with split rings C
between the two conical rings.
Fig. 9, Sheet II., shews a plan of the conical ring A as it is divided.
In the section, Fig. 10, Sheet II., the antifriction metal rings A are
cylindrical and enclosed in caoutchouc rings B, which, tending to be
swelled inwards by the pressure of the gland upon them, compress the
rings A against the rod.
Fig. 11, Sheet II., shews a plan of the rings A, each of which is in
two parts; they are arranged one above another so as to cross joint.
In Fig. 12, Sheet II., the packing ring A is spherical, divided as
shewn in the plan, Fig. 13, Sheet II. It rests on a cup B with a
caoutchouc ring C under it to give the necessary elasticity.

Fig. 14, Sheet II., represents a longitudinal section of packing for the
shaft of a screw propeller (with the packing partly in elevation), and
Fig. 15, Sheet II., shews an end view of the same. The divided anti-
friction ring A is made with feathers a, a, to prevent it from being
turned round. B is a caoutchouc ring which springs A in against the 2
shaft.
Fig. 16, Sheet II., represents packing for a piston, consisting of split
rings of antifriction metal A, A, of triangular section, pressed outwards
by a caoutchouc ring B.
Fig. 17, Sheet II., represents packing of like kind with rectangular 2
rings of antifriction metal A, A, pressed outwards by a caoutchouc
ring B.
Having thus described the nature of this Invention as communicated
to me by my foreign correspondent, I claim,--
First. The overlapping of the glands enclosing antifriction metallic 3
packing, substantially as represented in Fig. 1, Sheet I.
Second. The several arrangements and constructions of antifriction
metallic packing, substantially as represented in Figs. 2 to 13 inclusive,
Sheet II.
