Improvements in and Connected with Metallic Packing for Stuffing
Boxes and the like.
I, DAVID BROWN HUTTON of 5 Zingari Terrace Upton Park Essex, Engineer do
hereby declare the nature of this invention to be as follows:-—
This invention has for its object the better keeping of the stuffing Boxes of steam
or other engines perfectly tight and causing less wear and tear upon the rods,
plungers, or other parts of engines, working through the same.
It consists of a set of metallic rings in couples, encircled by a corrugated, flat spiral
or zig zag spring.
The metallic rings are made with an inclined plane, or coned, at any angle deemed
most suitable, on the side which the spring surrounds."
The convolutions of the spring are made of such a depth that the metallic rings, on
its being adjusted, or tightened up, are parted vertically of an inch, or more, as may
be desired. When the rings are compressed by the Gland being screwed, or
tightened up, these conical edges, reacting on the spring, forces them inwards,
towards the Rod or plunger.
The rings are in two halves and are stripped, or parted sufficiently, to prevent
them butting on their edges latterally, so that the reaction of the spring in pressing
them inwards, is received by the Rod or plunger, against which they bear, thus
ensureing a tight working fit. The spring is joined together by a clasp, with
adjusting screws. A distance piece is fitted inside the clasp, between the two ends
of the spring which can be stripped, to allow for any tightening of the spring that
may be required, to compensate for the wear of the metallic rings.

DAVID BROWN HUTTON 5 Zingari Terrace Gipsey Lane Upton Park Essex 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 :-
This invention consists of a set of Metallic Rings in couples, as shewn on the
appended sheet of Drawings, and marked A A Fig. 1, the said rings being encircled
by a corrugated, flat spiral, or zig zag spring B B.
The metallic rings are made with an inclined plane or coned, at any angle deemed
most suitable, on the side which the spring surrounds.
The convolutions of the spring are made of such a depth, that the metallic rings,
on its being adjusted or tightened up, are parted vertically of an inch or more as
may be desired."
The rings are split into two halves latterally in order to give them elasticity or
they may be divided into three segments for the same purpose, and are stripped
or parted sufficiently to prevent them butting on their edges in that direction.
When the rings A. A, are compressed by the Gland C, C, being screwed or
tightened up, their conical or inclined edges, press the spring in a vertical direction,
the reaction of which on the inclined planes of the aforementioned rings, forces them
inwards towards the Rod or plunger D, D, thus ensureing a tight working fit.
The spring is joined together by a clasp E Fig. 2 with adjusting screws.
A distance piece is fitted inside the clasp between the two ends of the spring which
can be stripped to allow for tightening up the spring as the rings may wear.
Two Brass washers are inserted with and placed on either side off and next to the
metallic packing rings, so as to allow of their free action, by intervening between
the ordinary packing on the one side and the stuffing box end on the other.
In the accompanying drawings Fig. 1, is a sectional elevation of a complete stuffing
Box. Fig. 2, a similar view in which the parts constituting the packing are not
shewn in section. Fig. 3 a plan of one of the rings forming the packing.
Having now particularly described and ascertained the nature of my said Invention,
and in what manner the same is to be performed, I declare that what I consider to be
novel and original, and therefore claim is,
First. In having a set of Two Metallic Rings in segments (whose outside diameters
are coned, or form an inclined plane) encircled by a clasped flat spiral, corrugated,
zig zag, or other spring, in combination with them, and acting in such a manner, that
on the compression of the abovementioned rings in a vertical direction, by the
tightening up of the Gland, the reaction of the spring on their coned or inclined
edges, forces them inwards towards the rod or plunger.
