PROVISIONAL SPECIFICATION.
Improvements relating to the Stuffing Boxes and Glands of Steam
Engines, Pumps, and the like.
I, JOHN SAMPSON STARNES, of 13 Broad Street, Radcliff, London, E.,
Engineer, do hereby declare the nature of this invention to be as follows:
My improvements are devised with a view to effect a very material saving in
the time occupied for removing the packing from the stuffing boxes of steam
engines, pumps, and the like.
It is well known that with the means hitherto adopted or available for effecting
the removal from and re-packing stuffing boxes; much valuable time is lost, this
is a very great drawback, and applies especially in the case of marine engines.
In accordance with my invention, an additional member to the ordinary packing
gland, is provided, serving the function of a flanged cylindrical sleeve or socket
piece, provided at the upper end with double flanges; that is to say; with an
upper and lower flange, with a space between sufficiently deep for the introduction
of a series of nuts arranged circumferentially between the two flanges and operated
by means of an ordinary spanner, and thereby caused to travel up and down fixed
screw bolts passing through the flange of the top of the stuffing box, the two
flanges of the supplementary sleeve or socket piece above referred to, and the
flange of the ordinary stuffing box gland. Thus, on its being. desired to remove
the packing from the stuffing box, for the purpose of re-packing, it is only
necessary to operate the nuts first mentioned so as to cause same to travel up the
fixed screw bolts aforesaid, whereupon the supplementary sleeve or socket piece
will be caused to travel up as also the ordinary gland, and the whole including the
packing be removed bodily from the stuffing box. Then upon the introduction of
the fresh packing, the whole packing device is restored to its normal position, upon
the nuts first above referred to, being operated in the reverse direction.

COMPLETE SPECIFICATION.
Improvements relating to the Stuffing Boxes and Glands of Steam
Engines, Pumps, and the like.
I, JOHN SAMPSON STARNES, of 13 Broad Street, Ratcliff, London, E.
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 :-
My improvements are devised with a view to effect a very material saving in
the time occupied for removing the packing from, and repacking the stuffing boxes
of steam engines, pumps and the like. My improved device may also be advan-
tageously fitted to stern shaft stuffing boxes.
It is well known that with the means hitherto adopted or available for effecting
the removal from, and repacking stuffing boxes, much valuable time is lost; this
is a very great drawback and applies especially in the case of marine engines.
And in order that my invention may be the better understood, I have appended
the accompanying sheet of drawings, in which
Figure 1, is a section of a stuffing box, shewing half of the packing and
cylindrical slieve;

page_text: Figure 2, shows half of the packing and cylindrical slieve removed from the
stuffing box;
Figure 3 is a plan of the packing; and
Figure 4 is an inverted view of the stuffing box, with the packing gland removed,
showing the cylindrical slieve and packing in halves.
Like letters of reference indicate corresponding parts in the several views.
In accordance with my invention, an additional member to the ordinary packing
gland is provided and which consists and serves the function of a split cylindrical
slieve or socket piece D provided at the upper end with flanges a and b; with a
space between the flange a, and the packing gland flange c, sufficiently deep for
the introduction of a series of nuts d arranged circumferentially between the two
flanges; and operated by means of an ordinary spanner, and thereby caused to
travel up and down fixed screw bolts E, secured to the flange of the top of the
stuffing box C, and passing through the flange a of the supplementary slieve
or socket piece, above referred to, and the flange of the ordinary stuffing box
gland c.
Thus, on its being desired to remove the packing B, from the stuffing box for
the purpose of repacking, it is only necessary to ease the set screws G, as shown
Figure 4, which loosens the flanged cylindrical slieve or socket piece D, thus
enabling the nuts d first above mentioned to be unscrewed, so as to cause same to
travel up the fixed screw bolts E aforesaid; whereupon, the cylindrical slieve or
socket piece D will be caused to travel up the piston rod A, as also the packing
gland F, and the whole, including the packing, be bodily removed from the stuffing
box C. Then upon the introduction of the fresh packing, the entire packing
device is restored to its normal position upon the two sets of nuts above referred
to, being screwed home.
By means of my invention, any stuffing box can be fitted with the cylindrical
slieve or socket piece D without alteration to the stuffing box or gland likewise,
as also any description of packing may be employed as the cylindrical slieve being
in halves, it is easily fitted and removed without damaging the piston rods,
spindles &c.
I find it advantageous also, to introduce a jamb washer H of rubber or the like,
between the cylindrical slieve flange a, and the stuffing box flange.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
:-
First. The improvements in stuffing boxes and glands, substantially as and for
the purposes herein set forth.
Second. In stuffing boxes, the removable slieve or socket piece D as and for the
purposes herein set forth.
