page_text: LETTERS PATENT to Edward Mitchell Blewett Faull, of 14, Dock Street, New-
port, in the County of Monmouth, for the Invention of "IMPROVEMENTS
IN PACKING THE GLANDS OF STEAM AND OTHER ENGINES."
Sealed the 25th February 1879, and dated the 25th September 1878.
PROVISIONAL SPECIFICATION left by the said Edward Mitchell Blewett
Faull at the Office of the Commissioners of Patents on the 25th September
1878.
EDWARD MITCHELL BLEWETT FAULL, of 14, Dock Street, Newport, in the
County of Monmouth. "IMPROVEMENTS IN PACKING THE GLANDS OF STEAM AND
OTHER ENGINES."
This Invention has for its object improvements in packing the glands of steam
and other engines.
For this purpose I employ a ring of gun metal, or it may be of other metal. This
ring bored out to fit the rod which is intended to work through it is coned or
tapered at its end, and it is divided into three or other number of parts. This ring
is used in conjunction with two other rings, which are hollowed out to correspond
to and receive the coned ends of the divided ring.
At the bottom of the gland one of the last-mentioned rings is placed, and within
the hollow of this ring the several parts of the divided ring are arranged around the
rod. Similarly the third ring is placed on the top of the divided ring, the coned
end of the divided ring being received into the corresponding hollow of the upper
ring.
A small quantity of ordinary fibrous packing to absorb the oil or lubricant is put
in over the upper ring, and the gland is loosely screwed down.
By the action of the inclined surfaces upon the rings, the one against the other,
the parts of the divided ring are drawn inwards, and made to embrace the rod
closely.
In order more effectually to prevent the escape of steam the divisions between
the parts of the divided ring are made in an oblique and zig-zag direction.

"
This Invention has for its object improvements in packing the glands of steam
and other engines.
For this purpose I employ a ring of gun metal, or it may be of other metal. This
ring bored out to fit the rod which is intended to work through it is coned or 1
tapered at its ends, and it is divided into three or other number of parts. This ring
is used in conjunction with two other rings, which are hollowed out to correspond
to and receive the coned ends of the divided ring.
At the bottom of the gland one of the last-mentioned rings is placed, and within
the hollow of this ring the several parts of the divided ring are arranged around 1
the rod. Similarly the third ring is placed on the top of the divided ring, the coned
end of the divided ring being received into the corresponding hollow of the upper
ring.
A small quantity of ordinary fibrous packing to absorb the oil or lubricant is put
in over the upper ring and the gland is loosely screwed down. By the action of 2
the inclined surfaces upon the rings, the one against the other, the parts of the
divided ring are drawn inwards and made to embrace the rod closely..
In order more effectually to prevent the escape of steam the divisions between
the parts of the divided ring are made in an oblique and zig-zag direction.
In order that my said Invention may be most fully understood and readily 2
carried into effect, I will proceed to describe the Drawing hereunto annexed.
DESCRIPTION OF THE DRAWING.
The Drawing shows a vertical section of a stuffing box or gland for a piston or
other rod packed in accordance with my Invention.
a is the stuffing box, bits cover, c the bolts for securing the cover, and d the a
piston rod. The box is of the ordinary construction, and within it there is placed
first the dished ring e, the under side of which is adapted to that of the bottom of
the box, and its upper side to the coned or tapered divided ring f. The ring fis
divided into parts, by preference three in number; these are similar the one to the
other, and fit together. Zig-zag joints are formed between the several parts, as is 3
shown in the Drawing at f'.
Over the divided ring f there is another dished ring g, the hollow of which, like
that of the ring e, is adapted to the form of the tapered ends of the divided ring f
1 represents a small quantity of fibrous packing applied over the upper ring g, and
between it and the gland b; it serves to hold the oil or lubricant, and introduces a 4
sufficient amount of elasticity between the gland and the rings e, f, and g.
The dished rings e and g are made truly to the taper of the ring f, so that there
may be a valve-like fit between these parts. The openings in the rings e and g should
be of a size to admit the rod d quite freely. The divided ring f is bored accurately
to the size of the rod, the joints between the parts of this ring being open to about
the amount indicated by the Drawing.
The bottom part of the divided ring f, with the zig-zag fitted accurately into the
coned ring e, forms a complete and effectual valve and seating. The ring e should
be put in with care, and made to fit perfectly steam-tight against the sides of the
box.
As wear takes place in use the inclines draw in the parts of the divided ring,
keeping them in steam-tight contact with the rod. When necessary the parts of

page_text: the ring should be filed, to restore the original amount of freedom in the joints
when it has been loosened by wear.
Glands packed in this manner are not only applicable to the piston rods of steam
engines and other piston rods, but also for pump rods, stern glands, and generally
where a packed gland is required. Often in the case of hydraulic glands, as for
example, the glands of pumps pumping cold water or other liquid, and stern glands,
the tapered divided ring f may advantageously be made of wood.
Having thus described the nature of my said Invention, and the manner of per-
forming the same, I would have it understood that I claim,-
First. Packing glands by means of tapered divided rings drawn together by
corresponding dished or inclined rings or surfaces pressed elastically thereon,
substantially as described.
Second. The combination within the cavity of a stuffing box or gland of the
parts e, f, g, and h, substantially as described.
In witness whereof, I, the said Edward Mitchell Blewett Faull, have here-
unto set my hand and seal, this Nineteenth day of March, in the year of
our Lord One thousand eight hundred and seventy-nine.
