113, Bedford Road, Bootle, in the County
Mancestria," do hereby declare the nature
This invention relates to packings or devices for packing piston and other
rods, and is designed to prevent, for example, leakage of steam from a cylinder
In carrying my invention into effect, I make my improved packing in any
suitable manner and of any required shape, but formed hollow through the centre
This I find secures free expansion, and it can be placed in glands very much
larger in diameter than other packings, which is an advantage as the packing
will last longer. It also allows of the ends being close together, besides in the
case of steam packing the steam can get into the hollow centre and tend to partly
counter balance the pressure on the outside Furthermore when the packing
becomes worn at one side by the fiction of the 1od or pressed out of shape, thus
enabling leakage to take place, all that is necessary is to forcibly squeeze the
packing in the stuffing box by pressing up the gland, and the packing will then
be forced back into its normal shape, it being far more flexible than solid
packing I propose to provide the stuffing box bush with an auxiliary conically
bored bush, which may be made in one piece with the main bush or made
separate therefiom This auxiliary bush may be made in two halves bolted or
Ivetted together If now the packing be placed in the stuffing box and pressed
up by the gland at one end against the conically bored bush at the other end,
the said packing will be pressed radially against the rod by the conical face of
the bush To secure the desired result more effectually, the packing at the
bottom of the box may be of small diameter, next a piece somewhat laiger and
eo on gradually increasing in diameter. In this way I am able to obtain an
admirable and secure packing for the rod

I, RICHARD ANTONIUS STEEN, of 113, Bedford Road, Bootle, in the County
of Lancaster, Chief Engineer of 88. Mancesta," do hereby declare the nature
of this invention and in what manner the same 18 to be performed. to be par-
ticularly described and ascertained in and by the following statement
1
This invention relates to packings or devices for packing piston and other
rods, and is designed to pierent, for example, leakage of steam from a cylindeı.
The invention will be understood from the following description, reference
being had to the accompanying drawings, in which,
Figure 1 is a sectional elevation showing my invention applied to a piston 10d;
Figures 2 and 3, slight modifications thereof,
Figure 4, a front elevation of the bush set forth in Figure 3.
Refening to these figures, A is the packing which is made in any suitable
manner and of any required shape, but formed hollow at B through the centie
This I find secures free expansion and it can be placed in glands very much
laige in diameter than other packings, which is an advantage as the packing
lasts longe It also allows of the ends being close together, besides in the case
of steam packing the steam can get into the hollow centre and tend to partly
counterbalance the pressure on the outside Furthermore when the packing
becomes worn at the side by the function of the 1od or pressed out of shape, thus
enabling leakage to take place, all that is necessary is to forcibly squeeze the
packing in the stuffing box by pressing up the gland and the packing will then
be forced back into its normal shape, it being far more flexible than solid
packing. C is an auxiliary conically bored bush placed in the stuffing box which
may be made in one piece with the main busli D, as shown in Figure 1, 01
separate therefrom as shown in Figures 3 and 4 This auxiliary bush may be
made in two halves as shown in Figure 4 bolted or vetted together with
webs acting as guides against the inside of the stuffing box to keep the bush
concentue with the rod If now the packing A he placed in the stuffing box
and pressed by the gland E at one end against the conically bored bush Cat the
other end, the said packing will be pressed radially against the 10d 1 by the
conical face of the bush C To secure the desired result more effectively,
the packing at the bottom of the box may be of smaller diameter, next a piece
somewhat larger and so gradually increasing in diameter In this way I am
enabled to secure an admnably secure packing for the rod It is obvious that
in place of providing the conically bored bush C, the stuffing box may be bored out
conically at G, as shown in Figure 2, so that the pressing of the gland E against the
packing will have the same effect of radially pressing the packing against the
rod, as in the other case On the bush C may be reversed, or the said bush might
be dispensed with, and the gland E bored out conically These arrangements
are mechanical equivalents of the other.
There is a space left at H for the condensed water, which is of an oily nature,
to collect m and lubricate both rod and packing The end of the gland at e mav
be shaped as shown in order to press the packing both against the rod and the
sides of stuffing box
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 claim 18
1 The improvement in packing or devices for packing piston and other rods,

page_text: which consists in providing the stuffing box with an auxiliary conically bored
bush made in one piece with the main bush or separate therefrom, whereby if
the packing in the stuffing box be pressed by the gland against the conically
bored hush, the said packing will be pressed radially against the 10d, sub-
stantially as described, or any meie mechanical equivalent thereof, such as boring
the stuffing box or the gland taper, and pressing the packing against the rod by
aid of this conical bore
2 In pachings for piston and other rods forming the successive layers of
pachings of gradually increasing diameter, whereby a conical packing is formed,
in combination with a conically bored stuffing box, or a comically boied bush or
a conically bored gland or then equivalents corresponding approximately in taper
to the tape of the packings substantially as and for the purpose set forth
3 In packings of the kind specihed in Claim 2, forming same hollow through
the centre, to secure fiec expansion while enabling the steam to get into the
hollow centie and tend to partly counterbalance the pressure on the outside sub-
stantially as described
4 The general combined arrangement and construction of parts forming my
improved packing devices for piston and other rods, substantially as set forth.
