PROVISIONAL SPECIFICATION.
Improvements in or relating to Packing for Stuffing-Boxes and
the like.
I, JOHN GILLIES REID of 6 Mount Pleasant Road, Henley Grove, Masborough,
Rotherham, in the County of York, Engineer's Brass Finisher, do hereby declare
the nature of this invention to be as follows:-
This invention relates to improvements in packing for stuffing-boxes and the
like, its object being to obtain a perfect tight packing as well as to prevent the
packing such as india-rubber rings, asbestos or the like from choking the steam
water or vapour way as is often the case for instance when gauge glass packing is
used, for in the case of india-rubber packing it sometimes surmounts the end of
the glass, and by the pressure of the steam either chokes the entrance to the gauge
glass or is forced into it.
To obviate this I place indiarubber, asbestos or the like rings into the ordinary
fittings, but at each side or top and bottom of the aforesaid rings I place a flanged
ring, notched serrated or saw-gated for allowing the contraction or expansion when
fixed over the glass and the outside edges of the packing rings, so that the flanges
prevent the packing rings from being moved; or in other instances the flanged
rings could be pinned or fixed on the packing rings in any suitable manner. The
flanged ring is preferably made taper, or with a knife edge so as to allow the
india rubber or other packing rings to tighten themselves when placed in position
and prevent the packing rings from ever coming into the entrance of the tube.
The usual stuffing box gland may be provided. The aforesaid improvements are
not limited to use with gauge-glass packing but are applicable with equal advan-
tage to other packings.

COMPLETE SPECIFICATION.
Improvements in or relating to Packing for Stuffing-boxes and
the like.
I, JOHN GILLIES REID, of 6 Mount Plea int Road, Henley Grove, Masborough,
Rotherham, in the County of York, Engineer's Brass Finisher, 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 relates to an improved packing for stuffing boxes and the like

page_text: its object being to obtain a tight packing as well as to prevent the packing such
as india-rubber rings, asbestos or the like from choking the steam, water or vapour
way as is often the case when gauge glass packing is used, for in the case of india-
rubber packing it sometimes surmounts the end of the glass and by the pressure
of the steam either chokes the entrance to the gauge glass or is forced into it.
In the accompanying drawings,
Figure 1 is a plan and
Figure 2 is an elevation of my packing ring.
Figure 3 is a sectional elevation of an ordinary gauge glass stuffing box, the
packing being under pressure.
Figure 4 is an elevation of a gauge glass with india-rubber packing and rings in
position previous to being placed in the stuffing box.
Like letters indicate like parts throughout the drawings.
In applying my improvements I stamp, press, mould or shape by convenient
means one or more rings A with flanges B of suitable metal or material and of
diameter to fit the size of the gauge glass or rod requiring packing, the ring A
being slightly tapered at its base and notched, serrated or cut as at A¹ to allow for
expansion and contraction when in position: the flange B also may be corrugated,
serrated, cut, perforated or indented as may be desired.
Having obtained the suitable rings A I preferably place one at the top of the
packing C and one at the bottom so that when placed in the stuffing box D they
form a compact packing and steam tight joint also preventing the rubber or other
packing from choking or getting into the gauge glass E, it being impossible for
it to move. The ring or rings A may be tapered to form a knife edge for better
fitting into the india-rubber or other packing.
I do not bind myself to the employment of my improved rings with gauge glass
packing as I may apply them elsewhere with equal advantage as they are appli-
cable for use with varying shapes of packing.
Having now particularly described and ascertained the nature of the said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The combination with gauge glass or other packings of one or more rings
such as A B substantiany as and for the purpose described.
2. The complete gauge glass or other packing substantially as described and
illustrated in the accompanying drawings.
