AN IMPROVED GLAND AND STUFFING BOX FOR WATER GAUGE FITTINGS FOR STEAM BOILERS
Year: 1885

page_text: I, THOMAS ROBINSON SUMMERSON Haughton le Skerne near Darlington in the
County of Durham Foundry assistant do hereby declare the nature of my
invention for AN IMPROVED GLAND AND STUFFING BOX FOR WATER GAUGE
FITTINGS FOR STEAM BOILERS to be as follows:-
(1st) A gap is cut in the circular rim of the stuffing box of sufficient width to
allow the glass tube to pass in. This gap is preferably the full internal depth of
the stuffing box. (2nd) The gland is made with a tongue of sufficient width to
close the gap in the stuffing box and of sufficient length to project past the bottom
of the gland so as to cover the packing beneath the gland.
The stuffing box may if desired be threaded in the inside instead of the outside
as shewn in the drawing and the gland may be made without a flange so as to
admit of being screwed down by an internal instead of an external gland nut. Or,
a screwed gland may be dispensed with and a gland may be made to be tightened
down with bolts through the flange.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a sectional elevation shewing the stuffing box and gland attached to the
bottom part of a set of water-gauge fittings. Fig. 2 is a front elevation. Fig. 3 is
a cross section taken through the line C. D. and Figs. 4 and 5 åre elevations of the
gland: The tongue of the gland which is the main feature of the improvement is
denoted by the letter b on each figure.

I, THOMAS ROBINSON SUMMERSON of Haughton le Skerne near Darlington
County of Durham Foundry Assistant do hereby declare the nature of my
invention for AN IMPROVED GLAND AND STUFFING BOX FOR WATER GAUGE
FITTINGS and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
"
A gap is cut in the rim of the stuffing box of sufficient width to allow the gauge
glass to enter and this gap is closed by a tongue which projects below the gland
sufficiently to retain the packing within the stuffing box. This tongue is pre-
ferably in one piece with the gland but may be attached to a
"washer upon
which the gland or gland nut immediately presses. The gap is preferably the
full depth of the interior of the stuffing box but may be made of less depth.
Any usual form of gland-nut may be used or the gland may be provided with a
projecting flange and be tightened down by screw bolts.
DESCRIPTION OF THE DRAWING.
Fig. 1 is a sectional elevation of the gland and stuffing box.
Fig. 2 is a front elevation with the gland-uut removed.
Fig. 3 is a cross section taken through the line A. B on Fig. 1.
The tongue on the gland which is the principal feature of the invention is
denoted by the letter "a" on each figure.
The gap in the stuffing box which is closed by the tongue enables the length of
the gauge glass to be readily and accurately ascertained and thus the danger from
a too short glass (obstruction by the packing) is avoided. It also enables a gauge
glass to be replaced with greater despatch than is the case with water gau, e
fittings of the ordinary description.
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
'
A stuffing box and gland for water gauge fittings for steam boilers as described.
The stuffing box is provided with a gap of sufficient width and depth to admit
the gauge glass. The gap is closed by a tongue which projects below the bottom
of the gland and is either made in one piece with it or is attached to a "washer"
upon which the gland or gland-nut immediately presses.
