JAMES GEORGE STIDDER, of No. 50, Southwark Bridge Road, in the County of
Surrey, Sanitary Engineer. "IMPROVEMENTS IN GLAND STUFFING BOXES FOR
WATER AND STEAM, ALSO IN SPINDLES AND RODS FOR THE SAME, AND IN
APPARATUS AND APPLIANCES USED IN CONNECTION THEREWITH."
My Invention consists of improvements in gland stuffing boxes for water and
steam, also in spindles and rods for the same, and in apparatus for withdrawing
the gland cover packing box and packing, and improvements in street boxes for
covering sluice valves when fixed in position.
My Invention, so far as it applies to street water valves, consists of a loose
internal stuffing box or receptacle for packing, which, after being filled with
packing material suitably compressed, is inserted into the outer or present form of
stuffing box, and the lower part of which inner or loose stuffing box presses upon
a suitable flexible ring or washer previously introduced into the bottom of the said
outer stuffing box; the screwing down of the gland cover in the usual way produces
a perfect water or steam tight joint.
For steam purposes the said loose box or receptacle for packing is made in two
longitudinal sectional parts for convenience in removing the packing from same.
My Invention also consists in making the valve spindle of water valves in two
parts, the upper one being removable and capable of being withdrawn from the
valve with the loose box or packing receptacle attached. In order to prevent the

page_text: entry of dirt into the stuffing box, I introduce a metal socket over the top of the
gland, fitting closely to the spindle.
For the purpose of removing the loose box or packing receptacle with its
contents and attachments when applied to sluice valves I make use of two hooked
rods loosely attached to a cross head, the latter being of such form as to admit of
its being prised from the surface of the ground by a crow bar or lever, the hooked
ends of the rods clutching the flange of the loose box or packing receptacle; the
latter is easily withdrawn.
My improved street box consists of an iron flanged frame furnished with a cover,
the latter being attached to the frame by a strong screw, which being relaxed
allows the cover to swing or turn as upon a pivot; the cover is also provided with
a small aperture and suitable stopper, the latter so constructed that when removed
from the said aperture for the purpose of operating upon the valve below it cannot
be detached from the cover or box.

My Invention consists of improvements in gland stuffing boxes for water and
steam, also in spindles and rods for the same, and in apparatus for withdrawing
the gland cover packing box and packing, and improvements in street boxes for
covering sluice valves when fixed in position.
My Invention, so far as it applies to street water valves, consists of a loose
internal stuffing box or receptacle for packing, which, after being filled with
packing material suitably compressed, is inserted into the outer or present form of
stuffing box, and the lower part of which inner or loose stuffing box presses upon
a suitable flexible ring or washer previously introduced into the bottom of the said
outer stuffing box; the screwing down of the gland cover in the usual way produces
a perfect water or steam tight joint.
For steam purposes the said loose box or receptacle for packing is made in two
longitudinal sectional parts for convenience in removing the packing from same.
My Invention also consists in making the valve spindle of water valves in two
parts, the upper one being removeable and capable of being withdrawn from the
valve with the loose box or packing receptacle attached. In order to prevent the
entry of dirt into the stuffing box, I introduce a metal socket over the top of the
gland, fitting closely to the spindle.
For the purpose of removing the loose box or packing receptacle, with its
contents and attachments, when applied to sluice valves, I make use of two hooked
rods loosely attached to a cross head, the latter being of such form as to admit of
its being prised from the surface of the ground by a crowbar or lever, the hooked
ends of the rods clutching the flange of the loose box or packing receptacle; the
latter is easily withdrawn.
My improved street box consists of an iron flanged frame furnished with a cover,
the latter being attached to the frame by a strong screw, which being relaxed
allows the cover to swing or turn as upon a pivot; the cover is also provided with
a small aperture and suitable stopper, the latter so constructed that when removed
from the said aperture for the purpose of operating upon the valve below, it cannot
be detached from the cover or box.
And in order that my said Invention may be more fully understood reference is
hereby made to the accompanying Drawings, and to the letters and figures marked
thereon.
Fig. 1 is a vertical section of a valve for water and other purposes; A is the
upper portion, and B the lower portion of the spindle, on which a screw thread is
cut and the lower end of which is tapered to fit into a socket, as shewn; D is an
elastic packing ring or washer fitted into the bottom of the stuffing box; E is an
ordinary gland held down and adjusted by screws, as shewn in Fig. 2; F is a loose
shield, which encircles the spindle A and prevents the entrance of dirt to the spindle
or packing; C is a loose stuffing box inserted in the outer stuffing box X and filled
with packing of any suitable description.
Fig. 2 is an elevation, transverse to Fig. 1, of the upper portion of the valve cover
and spindle, with hinged bolts G, G, for compressing the packing and keeping the

page_text: loose stuffing box C in position and maintaining the packing contained therein
tight and secure. The bolts G, G, are formed with knuckles H, H, to prevent their
falling laterally when the nuts are relaxed.
Fig. 3 is a perspective view of the upper portion of a valve placed below the
surface of the ground and shewing the method by which the loose stuffing box C
and upper portion of spindle A are removed from the valve beneath and drawn to
the surface of the ground for the purpose of cleaning or repacking; K, K, are
screwed dog-hooks connected together by the cross bar L; an application of the
lever M to the cross bar L enables the operator to withdraw the loose stuffing
box C and upper portion of spindle A (the nuts having been first removed). Old
packing can then be removed from the loose stuffing box C and new material
substituted, and the whole lowered and secured in position again without
disturbing the surrounding earth or enlarging the pit or hole in which the valve is
placed.
The loose stuffing box C can be applied to ordinary valve spindles made in one
piece, and can be withdrawn from the valve by the means above described.
Fig 4 is a section shewing the application of the loose stuffing box C to piston
or other rods having reciprocating or other motions, and used for steam or other
purposes, and in such cases the loose stuffing box C may be made in two parts, as
shewn in plan in Fig. 5, to facilitate its detachment from the rod when required to
be withdrawn from the cover or outer stuffing box N.
Figs. 6 and 7 are respectively a perspective elevation and cross section, shewing
the application of my said improvements to junctions or arrangements for drawing
water from mains and for other purposes.
Fig. 7 being a cross-section of the lower part only of the same, shewing the
lower portion of the valve attached to brackets K, K, the latter being secured to
the sides of the box J, J, by means of bolts; A is the pipe leading from the water
main; B is a screw down stop valve; C is the lower portion fitted with a bayonet
joint; D is the upper portion of the same joint forming the base of the stand
pipe E, which is furnished with two locking claws X, X, and has a pin inserted to
prevent removal of the stand pipe E when in use; E is a stand pipe, the interior
of which is lined with flexible material, as shewn in Fig. 6 at 0, 0, to prevent the
bursting of the stand pipe in frosty weather; F, Fig. 6 (in solid lines) is an
ordinary draw off cock, and G (in dotted lines) is a self closing valve, which can
be used in place of the ordinary draw off cock F, or that shewn in Fig. 8° may be
used; H is a dribble tap for drawing off any water remaining in stand pipe after
use.
Fig. 8 represents my improved ball valve in section; A is the outer case or
barrel screwed to the union B connected with the supply; B is fitted as a valve
seat at C; D is a plunger with bucket leather E attached to the same; F is a small
hole running longitudinally through the centre of the plunger and through which
water passes into the chamber X and exerts its pressure upon the bucket leather E,
the surface of the plunger at X being of larger area than that of the seating at
the opposite end of the plunger at C, the valve is more securely and effectually
closed when the buoyancy of the ball operates upon it; G is screw cap or cover
screwed upon the end of the barrel A; H is an ordinary ball or float; J is a lever
attached to the ball H and formed with a pinion on the end at K, as shewn, and
pivotted upon a fixed centre. The pinion K gears into the rack L, which passes
through a slot in the barrel A to the plunger D, and by means of the leverage or
buoyancy of the ball H. the plunger D is actuated and the valve opened or
closed.
Instead of the rack L being used three or more grooves may be made in the
plunger itself (as shewn in Fig. 8) for the segment K. to gear into.
Fig. 8 represents a modification of Fig. 8 for use as a self closing tap for stand
pipes, &c., the weight of the handle J closing the tap when let go.
Fig. 8b represents in sectional elevation a spring valve for regulating water
supply; A is a lever or handle; B is the body of the valve; C is a hollow plunger

page_text: connected with the spindle D; E, E, is a loose chamber with a flexible seating on
its bottom face; F, F, is a packing-ring to form a water tight joint. When the
lever A is let go it proceeds to resume its natural position, as shown by dotted
lines X; the spring G having become compressed forces the plunger C to the
bottom of the loose chamber E, E, and so closes the valve, but when the lever A is
pressed against or towards the body B of valve it lifts the plunger C and the loose
chamber E, E, with its valve seating from the seat at H and opens the valve; the
water then passes through the small aperture J and slowly enters the interior of
the hollow plunger C and loose chamber E, E, forcing the latter gradually to its
seat at H. The period or time for the valve to remain open is regulated by the
size of the hole J and the strength of the spring G.
Fig. 80 is another form of plunger and loose chamber, which in combination will
effect the same purpose as those described with respect to Fig. 8b; A is the outer
chamber; B is a solid plunger; C is the seating on the bottom side of the
plunger B; D is a bucket leather on the top of the plunger B; E is a small
aperture through which the water passes to the chamber A and gradually allows
the plunger B to fall, thus producing the same effect as that above described; F is
the spindle for lifting the chamber A and plunger B.
Either of these valves can
be worked by means of a screw in the place of springs.
Fig. 9 is a section, and Fig. 10 a plan of a street box and cover; A is the street
box cover; B is a loose plug fitting the aperture in the cover A and furnished
with the place C of such size and form as to preclude its detachment from the
cover A; D is a pin screwed in the centre and having a collar F on the lower end
and a slotted head, by means of which it is unscrewed from the lug E, but cannot
be withdrawn from the latter. The pin D when unscrewed from the lug E may be
lifted from the same as far as the collar will permit, and then acts as a pivot upon
which the cover A turns, but which effectually prevents the removal of the cover
from the box G. The dotted lines H on Fig. 10 shew the position of plug when
lifted from the aperture in the cover A.
Fig. 11 is a longitudinal section of a regulating flushing valve, and
Fig. 12 is a cross-section of the same valve on the line A, A, of Fig. 11.
Fig. 13 being a plan of the same. That portion of this double valve marked
B, B, B, B, was described and included in the Letters Patent granted to me, dated
February 11th, 1878, No. 569, and represented in Fig. 46, Sheet 3, of the Specification
thereof. C is an elastic diaphragm valve; D is a regulator attached to the cover
of the diaphragm valve C; in the interior of the regulator D is a spindle E formed
with feathers on the lower end; at F and G is a seating attached thereto; H is a
small cylinder enclosing the feathers F. The cylinder H works within a stuffing
box J, forming a watertight joint; K is also a small cylinder, which acts as a gland
to compress the packing; L is a lever, which on being raised lifts the spindle E
and brings the seating G in contact with the lower edge of the cylinder H, and
thus closes the regulator, which being done the water passing through the regulating
cock M (Fig. 12) and up the small aperture N, passes into the chamber O above the
diaphragın, by which means the seating P falls upon and closes the seat Q, and
thus prevents any further passage of water through the valve. The reverse
motion lowers the seating G and allows the water confined in the chamber O to
pass past the feathers F and out of the valve through the pipe R, R, in the
direction as indicated by the arrows. It thus sets the diaphragm free to act again
and allows a full flow of water through the valve.
The only purpose served by the valve B is to supply an after flush of water to
any apparatus with which it may be connected.
The spindles in Fig. 11 may be fitted with the moveable stuffing boxes shewn in
Figs. 1 to 5.
Having thus described the nature and object of my said Invention, I declare
that what I claim and desire to be secured to me is,-
1. The formation, construction, and arrangement of gland stuffing boxes, and
the several parts thereof, for the purposes and in the manner substantially as

page_text: herein before described and shewn on the Drawings, Figs. 1 to 5, or any mere
modification thereof.
2. The formation, construction, and arrangement of the several parts of moveable
stand pipes and junctions to main water pipes, substantially as herein before
described and shewn on the Drawings, Figs. 6 and 7, or any mere modification
thereof.
3. The formation, construction, and arrangement of valves controlled by a floatable
ball or by a simple lever, for the purposes substantially as herein before described
and shewn in Figs. 8, 8ª, 8b, and 8º, or any mere modification thereof.
4. The construction and arrangement of street boxes, substantially as herein-
before described and shewn in Figs. 9 and 10, or any mere modification thereof.
5. The construction and arrangement of such parts of flushing valves, in com-
bination with the parts marked B, substantially as hereinbefore described and
shewn in Figs. 11, 12, and 13, or any mere modification thereof.
6. The respective combinations of parts forming respectively my improvements
in gland stuffing boxes for water and steam, also in the spindles and rods for the
same, and in the apparatus and appliances used in connection therewith, substan-
tially in the manner and for the purposes herein before described and shewn
respectively on the Drawings.
In witness whereof, I, the said James George Stidder, have hereunto set my
hand and seal, this Twenty second day of April, in the year of our Lord
One thousand eight hundred and eighty two.
