"IMPROVEMENTS IN
HERBERT JOHN HADDAN, of Kensington, Middlesex,
PACKING RECEPTACLES AND GLANDS FOR PISTON-ROD PACKINGS." A communi-
cation from abroad by Otto Lonze, of Paris, France,
The invention relates to an improvement in piston-rod packing glands, and
metallic packing for steam engines and such like, so constructed as to allow the
gland or packing receptacle to be adjusted to a piston-rod in two or more pieces,
and when adjusted to remain intact and at the same time admit of being moved
laterally to keep in line with the piston-rod without coming apart. The object of
the invention is to render an automatic metallic packing applicable to piston rods
having both ends larger than the shaft or body of the piston-rod where it passes
through the packing. In one case the packing receptacle or gland is made in two
pieces held together by bands at each end and around the flange. In another case
the packing receptacle is made in three pieces, the conical part of the receptacle
being made in two pieces and fitted into the case which is in one piece, and holds
the conical part in place when adjusted to the piston rod, and is arranged to admit
of lateral play, so as to keep in line with the piston-rod and prevent uneven wear
or strain on the rod or packing.

HERBERT JOHN HADDAN, of Kensington, Middlesex "IMPROVEMENTS IN
PACKING RECEPTACLES AND GLANDS FOR PISTON-ROD PACKINGS." A communication
from abroad by Otto Lonze of Paris, France.
This invention relates to an improvement in piston rod packing glands, and
metallic packing for steam engines and such like so constructed as to allow the
gland or packing receptacle to be adjusted to a piston rod in two or more pieces
and when adjusted to remain intack and at the same time admit of being moved
laterally to keep in line with the piston rod without coming apart.
The object of the invention is to render an automatic metallic packing applicable
to piston rods having both ends larger than the shaft or body of the piston rod
where it passes through the packing.
In one case the packing receptacle or gland is made in two pieces held together
by bands at each end and around the flange.
In another case the packing receptacle is made in three pieces, the conical part
of the receptacle being made in two pieces and fitted into the case which is in one
piece, and holds the conical part in place when adjusted to the piston rod, and is
arranged to admit of lateral play so as to keep in line with the piston rod and
prevent uneven wear or strain on the rod or packing.
In the accompanying drawings C is the cap which holds the split gland or
packing receptacle in place. H¹ the packing receptacle or split gland. A, A', A¹¹
rings which hold the packing receptacle or split gland in place and prevent it from
coming apart. M is the follower also in two pieces and held intack by the ring M³
at one end and by passing into the packing receptacle or split gland at the other
end. F is a bushing ring also in two pieces and held intack by the ring G. E is
the spiral spring which automatically feeds the packing rings forward into the
conical part of the packing receptacle and causes them to be forced to a bearing on
the rod and form a steam tight joint. Ring All is ground to a steam tight joint
in the recess in the cap, said ring is of less diameter than the diameter of the
recess, thus allowing space for the packing receptacle to movo laterally to keep in
line with the cross head. By this device a skilled mechanic is enabled to apply a
conical packing gland to a piston rod having its ends larger than the body of the
rod where the packing receptacle or gland is required to fit and still be able to
realize all the advantages of a movable packing receptacle. Sectional packing rings
of metal of any desired composition may he need
CLAIMS.
1st. A gland made to contain a movable packing receptacle in two or more
pieces as shown and described.
2nd. A receptacle for metallic packing made in two or more pieces and
adjustable to a piston rod having either end of greater diameter than the body or
shaft of the rod where it runs through the packing.
In Witness whereof I the said Herbert John Haddan have hereunto set my
hand and seal this twenty-fifth day of August A.D. 1882.
