PROVISIONAL SPECIFICATION.
Improvements in Stuffing Boxes and in Packing for the same.
We, JAMES CONLONG, of Livsey Branch Road, Ewood Blackburn, Engineer,
and JOHN WILLIAM WELDING, of 12, Darwen Street, Blackburn, Bone-manure
Manufacturer, both in the County of Lancaster, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improvements in stuffing boxes and packing for the
same and has for its object to render the same less liable to the action of the
vapour or fluid and thus effect a better and more durable joint than heretofore has
been the case.
Referring to the first part of our improvements we fit into the ordinary stuffing
box an additional stuffing box or receptacle the inner end of which is formed with a
bottom through which the rod or spindle to be kept tight passes and the outer end
with a flange to permit of bolting the same to the flange of the ordinary stuffing box
in the usual manner. The outer end of the said additional stuffing box we form
internally with a thread to receive a correspondingly threaded cylindrical collar or
nut through which the said rod or spindle passes. Between the said threaded collar
or nut and the bottom of the additional stuffing box we fit into the same a series of
pairs of collars formed internally with a conical hole through which the said rod or
spindle passes.
Referring to the second part of our improvements we form the packing to be
placed into the stuffing box of brass or other metal shavings or of fine wire wound
into a conical body. For the purpose of giving body to the said brass or other
metal shavings or fine wire, we mix therewith powdered asbestos, soap stone and
boiled oil, which composition is ramed into the said coned collars around the said
rod or spindle in the usual manner. By screwing the aforesaid threaded collar or
nut onto the top of the series of collars and by reason of their conical internal shape,
the said composition is forced tightly around the said rod or spindle and thus forms
a durable and also self lubricating joint.

COMPLETE SPECIFICATION.
Improvements in Stuffing Boxes and in Packing for the same.
We, JAMES CONLONG, of Livsey Branch Road, Ewood, Blackburn, Engineer,
and JOHN WILLIAM WELDING, of 12, Darwen Street, Blackburn, Bone-manure
Manufacturer, both in the County of Lancaster, 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 improvements in stuffing boxes and packing for the same
and has for its object to render the same less liable to the action of the vapour or
fluid and thus effect a better and more durable joint than heretofore has been
the case.
And in order that our invention may be more fully understood we have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Figs. 1 & 2 are both longitudinal sections of two various forms of stuffing
box or gland.

page_text: In carrying out and referring to the first part of our improvements and more
particularly to Fig. 1, we fit into the ordinary stuffing box a an additional stufling
box or receptacle the inner end of which is formed with a bottom through
which the rod or spindle c to be kept tight passes and the outer end with a flange 2
to permit of bolting the same to the flange a' of the ordinary stuffing box a in the
usual manner by means of bolts d, a packing ring e being placed between the same.
The outer end of the additional stuffing box b, we form externally with a thread to
receive a correspondingly threaded cylindrical collar or nut, through which the
rod or spindle passes. Between the threaded collar or nut and the bottom of
the additional stuffing box 6 we fit into the same a series of pairs of collars g formed
internally conical through which the rod or spindle c passes.
Referring to the second part of our improvements, we form the packing to be
placed into the stuffing box of brass or other metal shavings or fibres hor of fine
wire wound into a conical body. For the purpose of giving body to the brass or
other metal shavings or fibres or fine wire, we mix therewith powdered asbestos,
soap stone and boiled oil, which composition is ramed into the said coned collars
around the said rod or spindle c in the usual manner. By screwing the threaded
collar or nut onto the top of the series of collars g and by reason of their conical
internal shape, the said composition is forced tightly around the rod or spindle a
and thus forms a durable and also self-lubricating joint.
b
In lieu of employing a collar or nut as described, we may fit into the upper end
of the additional stuffing box or receptacle a collar having a flange f', which is
rendered adjustable therein by means of nuts and threaded studs d. The upper ends
of which are passed through the flange and the lower ends through the additional
stuffing box or receptacle screwed into the stuffing box a.
We may also remark that in lieu of arranging the coned collars g in pairs, as
shown in Fig. 1, they may be arranged as shown in Fig. 2, viz., the coned side of
one facing the flat side of the other and that in small stuffing boxes, if deemed
necessary the coned collars y may be to some extent dispensed with.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, we declare that what we
claim, is-
"In stuffing boxes and in packing for the same
1st. The employment inside of an ordinary stuffing box a of an additional stuffing
box or receptacle b, suitably secured therein and containing a series of coned collars g,
adapted to receive between the same packing and be adjusted so as to compress
and force the packing tightly against the rod or spindle c, substantially as set
forth.
2nd. A packing, consisting of metallic fibres or fine wire mixed with powdered
asbestos, soap stone and boiled oil, or the like, substantially as set forth.
