PROVISIONAL SPECIFICATION.
Improved Construction of Stuffing-box for the Reciprocating Rods
of Steam-engines and other Motors.
I, EDWARD ERNEST SALE, Winton Terrace Stoke-on-Trent Staffordshire,
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
:―
This my invention has reference to an improved removable stuffing-box and
packing for the reciprocating rods of steam-engines, gas-engines and other motors,
the object of my said invention being to make such removable stuffing-boxes, so
that packing can be readily placed therein, and placed in position within the
stuffing-box of such motors.
In carrying my said invention into practice I make a cylindrically shaped packing
receptacle or case of or from cast-iron, brass, gun-metal, or other suitable metal or
alloy with a detachable gland, and detachable inner end, of any suitable size, the
outer end of such casing having a circular or other suitably shaped projecting
flange formed thereon, so as to enable same to be connected by screws, bolts or
other suitable means to the aforesaid detachable gland, the inner detachable end or
length of such cylindrical casing fitting easy upon its piston or other rod, the inner
diameter of the outer length of such casing I bore larger than its rod, so that two
or more segmentally divided rings of antifriction metal of suitable size may be
clasped around a piston or other rod by means of a suitable metallic spring or
springs, and the outer end of such casing slid over such antifriction-metal rings
and springs, the inner end of the detachable portion of the casing at its joint with
the inner end of the outer portion of such casing may be slightly conical so as to
fit into the conical neck or seating on the inner end of such outer portion, or the
inner end of the shorter length of such casing may be screwed so as to engage with
an internal thread on the inner end of the outer portion of the casing, the gland
instead of being detachable may be cast or formed in one with the outer length of
the casing, and have a suitably shaped recess formed within same for receiving
lubricant.
After packing such as described has been placed around a piston or other rod;
the two portions of such casing are joined together by screwing or other means so
that the packing will be enclosed or covered by the outer portion of such casing,
such transversely divided packing receptacle and the packing are then slid along
the shaft or rod into the stuffing-box of the cylinder, and secured therein by means
of studs or bolts.

page_text: Improved Construction of Stuffing-box for the Reciprocating Rods
of Steam-engines and other Motors.
I, EDWARD ERNEST SALE Winton Terrace Stoke-on-Trent, Staffordshire,
Mechanical 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 my invention has reference to an improved removable and renewable
stuffing-box and packing for the reciprocating rods of steam-engines, gas-engines
and other motors, the object of my said invention being to make such cylinders
or stuffing-boxes so that metallic packing can be readily placed therein, and then
fitted or fixed within the stuffing-boxes of such motors, or such packing may be
first placed in the stuffing boxes of such motors and such cylinder or casing
afterwards slid along the piston or other rod of such motors over or around the
packing within such stuffing-boxes.
In carrying my said invention into practice I make such packing-boxes, packing-
cylinders, packing-receptacles or packing sheaths of various sizes and thickness or
thicknesses by moulding, casting or other means, of or from cast-irou, brass, gun-
metal or other suitable metal or metallic alloy having one of their ends threaded so
that they may be screwed into the inner side of the gland of the stuffing boxes of
such motors, or I form a suitable projecting flange on or around the outer periphery
of one of the ends of each of such liners or packing receptacles, or such flanged
receptacles may be longitudinally divided, and attached by metallic screws or the
like to the inner side of the gland of such stuffing-boxes, such projecting flange
or rims when in their normal position fitting into a suitable recess formed in
the outer end surface of the stuffing-boxes of such motors, the internal diameter
of each of such packing-cases or packing-receptacles I make about one-third
larger than the rod around which they are fitted or placed so that two or more
segmentally divided rings of any suitable anti-friction metal may be clasped around
the said piston or other rod at a suitable distance or distances apart by means of
springs of suitable thickness made of or from sheet steel or other suitable metal,
and two divided intermediate anti-friction or other suitable metallic rings forced
or kept apart by a suitable metallic spring may be covered or surrounded by
such casings or receptacles within such stuffing-boxes. Sometimes I prefer to use
such metallic packing without such casings or receptacles; but by using such
receptacles such metallic packing is more readily withdrawn from the stuffing-box
of the motor within which it is fitted or placed, or when it is required to inspect,
remove or renew same.
In order that my said invention may be more readily understood and explained
in detail I have hereunto annexed a sheet of drawings on which letters of reference
are marked on corresponding parts on all the figures alike.
DESCRIPTION OF DRAWINGS.
Figure 1 represents a side sectional elevation of an ordinary stuffing-box such as
is usually cast on or in one with the fore-end, or front end cover of the horizontal
cylinders of steam-engines or the like motors, shewing my improved metallic
packing fitted therein and around that portion of a metallic piston rod passing
through such stuffing-box.
Figure 2 represents a front elevation of the collar end of the segmentally divided
anti-friction metal rings of such packing.
Figure 3 represents a similar elevation to that shewn at Figure 2 without the
removable split ring.

page_text: segmentally divided anti-friction rings.
Figure 5 represents a side elevation or edge view of either half of the segmentally
divided rings at the fore-end or gland-end of such stuffing boxes.
Figure 6 represents a side elevation or edge view of a portion of the outer or
curved surface of such segmentally divided rings, shewing the form of joint I
usually adopt for such rings.
Figure 7 represents a front elevation of each half of the aforesaid segmentally
divided rings.
Figure 8 represents a front elevation of either of the divided intermediate anti-
friction metal rings, and
Figure 9 represents a transverse sectional elevation of either of the intermediate
rings taken through line a- on Figure 8, looking in the direction indicated by the
arrow.
On reference to the drawings a represents the ordinary form of stuffing box which
is usually formed on, or cast in one with the cylinder covers of steam-engines or the
like motors.
It will be understood that after the divided intermediate rings b made of or from
Babbitt's metal, white brass or other like suitable, anti-friction metal with the
interposed steel or other suitable metallic spring c and the segmentally divided
rings d made of or from white brass, Babbitt's metal or the like suitable anti-
friction metal have been fitted and clasped on or around a steel, wrought-iron
or other piston rod e by means of springs made of or from sheet steel or other
suitable metal, the sleeve, liner or packing receptacle made of or from gun-
metal, brass or other suitable metal attached by its flange to the inner side
or surface of the metallic gland i by means of metallic screws j is slid over or
around such packing, the ends of two or more metallic screws, pins or the like k
(shewn in dotted lines) may be passed through such sleeves or liners near to
their rear end into a suitable groove or recess / formed by any suitable means
in and around the collar of the segmentally divided anti-friction metal ring
nearest to the rear end of the stuffing-box a so as to retain such packing within
such liners or sleeve g. The gland having the liner or sleeve 9 attached
thereto being then secured to the flange of the stuffing-box a by any suitable
number of bolts and nuts or other suitable means so that the said sleeve or
liner g will fit into and be secured within such stuffing-box. When such improved
metallic packing is intended for use in stuffing-boxes fitted with a neck-ring
(shewn in dotted lines) having a curved surface it will be readily understood
that the surface of the segmentally or other divided anti-friction metal ring at
the rear end of the liner or packing receptacle will also be formed with a curved
surface for bearing or fitting against the curved surface of such neck ring.
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
1st. The construction, and arrangement of metallic packing for use in the stuffing-
boxes of steam-engines and other motors having reciprocating rods, of two rings of
white bronze, Babbitt's metal or other suitable anti-friction metal, each ring being
divided into two parts, or halves transversely to their axis, and kept apart on such
rods by means of an interposed steel or other suitable metallic spring, a ring of
Babbitt's metal, white bronze or other suitable anti-friction metal divided into two
parts, or halves transversely to their axis having a segmental or other suitable joint
or joints, and clasped on or around such rods close against each of the afore-
mentioned divided anti-friction rings by a spring or springs made of or from sheet
steel or other suitable metal, as herein substantially described and set forth.
2nd. The construction and arrangement of metallic packing for use in the stuffing-
boxes of steam-engines and other motors having reciprocating rods, of two rings of
white bronze, Babbitt's metal or other suitable anti-friction metal, each ring being

or joints, and clasped on or around such reciprocating rods close against each of the
aforementioned divided anti-friction rings by a spring or springs made of or from
sheet steel or other suitable metal, and enclosed or covered by or with a gun-metal
or other suitable metallic sleeve, cylinder or the like with open ends, having one of
their ends screwed, so that such sleeves or cylinders may be screwed or fastened
into the inner or under side of the gland of such stuffing-boxes, or a longitudinally
divided metallic sleeve with a suitable projecting flange or rim, or a metallic sleeve
with a suitable flange may be used, for enabling such cylinders or sleeves to be
fastened or connected to the under side of such gland flanges by metallic bolts and
nuts, metallic studs or the like suitable means as herein described, set forth and
illustrated on the drawings hereto annexed.
