PROVISIONAL SPECIFICATION.
Improvements in Metallic Packing for Stuffing Boxes.
I, CARLO COZZI, of No. 26 Via Lazzaretto Vechino, Trieste, in the Empire of
Austria, Engineer do hereby declare the nature of this invention to be as
follows:-
:-
My invention relates to metallic packings for stuffing-boxes and has more
especially for its object to provide a yielding metallic packing which can be readily
and entirely taken to pieces for the purpose of removing worn-out parts and
replacing them by new ones.
My improved metallic packing can be mounted in any existing stuffing box.
My improved metallic packing consists of an outer casing made in two halves
held together in any suitable manner. In this outer casing two rings are arranged
one above the other, each of these rings consisting of two halves held together by
screws, or in any other suitable manner. These rings are provided with inwardly
projecting bevelled shoulders on their inner surface, the top one at its top, the
bottom one at its bottom.
Between these two rings I arrange another central ring consisting of two loose
halves and having its inner surface bevelled at the top and bottom.
Between the bevels of the central ring and each of the top and bottom rings
respectively I arrange two solid metallic packing rings each of which is bevelled
exteriorly to correspond with the bevelled inner surfaces of the said central ring
and the top or bottom respectively, so that the packing rings of each pair are held
together and kept in immediate contact with the rod or shaft by the said central
ring and the top or bottom ring respectively. Springs inserted between either the
top or the bottom of the stuffing box casing and either the top or the bottom ring
respectively produce a suitable pressure to ensure a tight joint between the said
packing rings and the rod or shaft.

Improvements in Metallic Packing for Stuffing Boxes.
I, CARLO Cozzi, of Lazzaretto Vechino No. 26, Trieste, in the Empire of
Austria, 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 metallic packings for stuffing boxes and has more
especially for its object to provide a yielding metallic packing which can be readily
and entirely taken to pieces for the purpose of removing worn out parts and
replacing them by new ones.
My improved metallic packing can be arranged or mounted in any existing
stuffing box.
In the accomnenwing dramine

page_text: The left half of Figure 2 is a section on line a. Figure 1 and
The right half of Figure 2 is a section on line y y Figure 1 always looking in
the direction of the arrows.
My improved metallic packing consists of an outer casing B made in two halves
and held together in any suitable manner. In this outer casing two rings C C are
arranged one above the other, each of these rings consisting of two halves held
together by screws or in any other suitable manner. These rings are provided with
inwardly projecting bevelled shoulders on their inner surface; the top one at its
top, the bottom one at its bottom.
Between these two rings I arrange another central ring C¹ consisting of two
loose halves and having its inner surface bevelled at the top and bottom.
Between the bevels of the central ring C¹ and each of the top and bottom
rings CC respectively I arrange two solid metallic packing rings D D each of
which is bevelled exteriorly to correspond with the bevelled inner surfaces of the
said central ring C and the top or bottom respectively, so that the packing rings
of each pair are held together and kept in immediate contact with the rod or
shaft A by the said.central ring C' and the top or bottom ring CC respectively.
Springs E inserted between either the top or the bottom of the stuffing box casing
and either the top or the bottom ring C respectively produce a suitable pressure to
ensure a tight joint betweeen the said packing rings D D and the rod or shaft A.
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 :-
A metallic packing for stuffing boxes consisting of the outer casing B made in
halves, the top and bottom rings C C also made in halves, loosely placed therein
and provided with bevelled shoulders, the central ring C₁ composed of two loose
balves, and the solid packing rings D D correspondingly bevelled between the
central ring and the top and bottom rings C C, and springs E E holding all the
rings against each other and keeping the packing rings D D against the rod or
shaft A substantially as described and shown in the drawing.
