I, JOSEPH SMITH, of 36, Wilson Street, Middlesbrough, in the County of Yorkshire;'
Marine Engineer, do hereby declare the nature of this invention to be as
follows:-
At the inner end of the stuffing box and fitting it, is a brass collar in two'
pieces. At a short distance from the foregoing, is another brass collar, in two pieces
and exactly similar. These two Brass collars are kept apart by compression springs..
In contact with the second brass collar described, is a brass ring in two pieces, of a
wedge shaped section, in contact with this Brass Ring and fitting it, is another brass
ring in two pieces. This ring may be grooved on its exterior to take in carrying
springs, if needed. The inner sides of the last two Brass rings described are
recessed, so as to admit two white metal rings, each in three pieces. In contact
with the second brass ring, is a brass collar in two pieces, filling space between piston
rod & stuffing box. One turn of asbestos packing may be fitted between the
metallic packing and the Gland, where no drain cock is used.

I, JOSEPH SMITH, of 36, Wilson Street, Middlesbrough, in the County of Yorkshire,
Marine Engineer, 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 :-
The particular object of this invention, is to make steam and water-tight, all
kinds of piston rods or rams, where they pass through a stuffing box.
The drawing, shows a stuffing box in longitudinal section, with the metallic packing
therein.
At the inner end of the stuffing box, and fitting, and thrusting against it, is a
brass collar or ring a, in two equal pieces, having six pins or studs b, secured on its
face at equal distances. At a short distance from the foregoing collar or ring a, is
another brass collar or ring c, exactly like the foregoing collar or ring a, in every way.
These two brass collars or rings a, and c, are kept apart by six compression
springs d, the ends of these said compression springs d, are slipped
over the pins or studs 6, on the above-mentioned collars or rings a,

page_text: and c.
In contact with the collar or ring c, is a brass ring e,
in two equal
pieces, of a wedge-shaped section. In contact with this brass ring e, and fitting
outside of it, is another brass ring f, also, of a wedge-shaped section, and in two
equal pieces. This ring f, has circular recesses g, in it, at equal distances on its
outer circumference. In the said circular recesses-g, are fitted compression carrying
springs h. The inner sides of the two brass rings e, and f, are recessed, so as to
admit two white metal rings i, and j, each in three equal pieces, which constitute the
metal-packing. In contact with the ring f, is a brass ring k, in equal parts, of a
wedge-shaped section, fitting outside of the ring k, is another ring 1, in equal parts,
and also, of a wedge-shaped section. Next to the aforesaid rings k, and L, is a
collar or ring m, exactly similar to the rings or collars a, and c, except, that it has
no pins or studs on its face. Against the ring or collar m, the spigot of the gland
presses. I find from experience, there is no necessity for the turn of asbestos
mentioned in the Provisional Specification, the packing being steam, and water-tight,
without...
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 :-
The peculiar construction and arrangement of rings or collars, in two and three
pieces, with pins or studs, compression springs, and carrying springs, as described and
illustrated in, the accompanying drawing.
