PROVISIONAL SPECIFICATION.
An Improved Method of Packing the Glands of Steam and other
Engines, Pumps, and the like.
EDWARD MITCHELL BLEWETT FAULL Consulting Engineer & Marine Surveyor
of 30 Manley Terrace, Kennington Park in the County of Surrey London S.E. I do
hereby declare the nature of this invention to be as follows:-
That I pack the glands of steam and other engines by means of a metallic triple
beat valve, the seating of which is placed on the top of a flat surfaced plate, which
is made to fit the bottom of the stuffing box, the inside valve forms a tongue piece
for the segments of the outside valve.
And I hereby declare the nature of my patent, to be a triple beat valve & seating
through which the piston rod, ram, tail end shaft, or other rod or shaft, may be
required to work.
1st. I place in the bottom of the stuffing box a metallic ring. One side of this
metallic ring is made to the shape of the bottom of the stuffing box. The other side
of this ring is made perfectly flat, on which the valve seating is placed.
2nd. The valve seating is placed next this plate, forming a perfectly steam tight
joint where the two faces meet. The top side of this seating is bored out to receive
two valves, the inside valve which is placed at the lower part of the seating is cut
open on one side, in order to allow for wear, and is ground perfectly steam tight into
the seating.
3rd. The outside valve is recessed out, covers the lower valve, & forms another
beat on the top, & around the side of the inside valve; the outside valve is then cut
into parts, one, two, three, or any other number that may be desired. Each of the
segments of the outside valve, is dowelled into the inside valve, & is ground into the
seating at the same time as the inside valve, the inside valve thus forming a perfect
steam tight tongue, for the segments of the outside valve.
On the top of the outside valve is placed a conical compression ring, on the top
of which is placed one turn of fibrous packing, to give the necessary amount of
elasticity, & to retain lubrication, (a spiral or other spring may also be used for this
purpose) the gland is then screwed down in the usual manner, which presses the
segments of the valves together, thus embracing the rods, or rams, in a perfectly steam
tight manner, as shown in the annexed drawings.
A. represents the bottom of the stuffing box.
B. is the surfaced ring, the bottom side of which is made to fit the bottom of
the stuffing box, the top of the same ring being faced up accurately, to receive the
bottom of the valve seating.
C. is the valve seating, which is coned out to receive two valves.
D. is the inner valve, which is cut open on one side, in order to allow for com-
pression to the rod, and to allow for wear
E. is the outer valve which is cut into two, three, or any other number of pieces.
It will be seen that the inside of this valve, is bored out to receive the valve D, and
that they are dowelled together, in order to cover the spaces in the inside and outside
valves.
The top of the valve D forms the third beat, and when bedded into the beat—as
shown into the recessed part of the valve E-produces an uniform pressure on each
end of D.
The top end of E. is made conical in the same proportion as the valve seating,
and on the top of E. is placed a coned ring, for the purpose of forcing the top
ends of the valve E. closely to the rod.

page_text: This packing may be made of cast iron, gun, or white metal, or any other
material.
Having now fully described the nature of my invention, I hereby claim the right
of packing stuffing boxes, by means of a metallic valve, with one, two, three, or any
other number of beats, substantially as above described.
Dated this 17th day of October 1889.

COMPLETE SPECIFICATION.
An Improved Method of Packing the Glands of Steam and other
Engines, Pumps, and the like.
EDWARD MITCHELL BLEWETT FAULL, Consulting Engineer, of 30 Manley Terrace
Kennington Park,. in the County of Surrey London S.E. 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 has for its object the application of an improved packing for
piston rods, valve rods, pump rams, stern glands, and the like: It is more especially.
adapted for the present triple, and quadruple expansion engines. Thus, in order to
meet the requirements of such rapidly increasing pressures, I have introduced my
triple beat metallic valve packing, which will withstand any pressure, and any degree
of temperature, it is automatic and floating in its action and is made of cast iron,
gunmetal, wood (for stern glands) or any other material. The construction of
which, will be seen by the annexed drawings, to be free from all unnecessary complica-
tions, which is usually the cause of numerous defects and troubles.
In order that my Invention may be clearly understood;. I refer to drawings. filed
in provisional specification.
A. represents the stuffing box of a cylinder or pump..
B. is placed in the bottom of the stuffing box, the bottom part of which is made
to fit the angle, to which the bottom is bored, and it is carefully jointed, to prevent
any steam passing on, to the outside of the packing. The top part of this ring, is
scraped up to a steam tight surface, on which I place the valve seating.
C. is the valve seating, the bottom part of which is made steam tight, with the
top of the floating ring B. C is also made smaller in proportion to the stuffing
box, in order to allow the packing to float freely, and is bored out slightly to clear the
rod.
D. is the inner valve, the bottom part of which is ground into the valve seating,.
and forms No. 1 beat. The inside of this valve is bored out, to fit the rod accurately,
thus forming a steam tight face against the rod, the top end of this valve, is ground
into the valve E and forms the 2nd beat.
E is the outside valve. The bottom part of this valve covers the inside valve,
and is ground into the valve seating C. thus forming the triple beat. The inside
of this valve above No. 2 beat-is bored out to fit the rod closely, and also forms,
a steam tight joint against the rod.
'
After the process of grinding the valve faces is completed, the outside valve is
cut into 2, 3 or any other number of pieces. The inside valve is in one or two!
pieces, and dowelled together in such a manner as to form a tongue piece, thus the
inside valve forms a tongue piece for the outside valve, and vice versa.
F. is the compression ring, which is bored out to fit the outside valve, this ring is
also made to clear the sides of the stuffing box, in precisely the same manner as all
the other parts of the packing, the inside of F. is bored to clear the rod freely; thus
giving perfect freedom to the rod.
On the top of the compression ring is placed a turn of tucks or other fibrous.
packing. But should the automatic principal be desired, we apply a spring or
springs, and screw a plate on to the top of the stuffing box, bored out to clear the
rod, and jointed on the face.

page_text: Having now fully described and ascertained the nature of my invention, and in
what manner the same is to be performed, I declare that what I claim is :-
1st. The use and manufacture of metallic packings for stuffing boxes, to be made
of cast iron, gunmetal, wood, or any other material, floating and automatic.
2nd. The triple, or other number of beats substantially as described.
3rd. To be used with the ordinary gland, and a turn of tucks or other fibrous
packing, or to work it without the ordinary gland, by means of a spring or springs,
with a jointed plate on the top of the stuffing box.
Dated this March 13th 1890.
