PROVISIONAL SPECIFICATION.
Improvements in Supports for Drying Cylinders.
I JOSEPH JOHNSON SUMNER, of Bank View, Furness Vale, near Stockport,
in the County of Chester, do hereby declare the nature of this invention to be as
follows:-
My invention relates to the standards or pedestals which sustain the cylinders
of drying machines and particularly to the standards which are provided with
stuffing boxes and with means for supplying steam to the cylinders. As ordinarily
constructed the upper end of each standard is adapted to receive the gudgeon of
the cylinder and is provided with an adjustable gland and with packing in which
the said gudgeon revolves.
As the drying cylinder is comparatively heavy the gudgeon tends to wear the
lower side of the bearing which sustains the weight so that in course of time
the axis of the gudgeon is lowered and does not coincide with the axis of the
gland and bearing.
To remedy this defect I provide the standard with an adjustable bearing which
sustains the weight and which can be raised whenever desirable so as to restore
the axis of the gudgeon to its proper working level.
The said bearing may consist of a half step of brass or other suitable metal
or alloy seated in a recess in front of the stuffing box and fitted to slide
vertically.
The adjustment may be effected by means of a screw or of a cottar or by
other suitable means. A passage is formed to permit of the escape of water
between the stuffing box and the bearing so as to check the passage of water to
the bearing. It may not be necessary to bore the head of the standard to receive
the gudgeon.
The bearing may be lubricated in any suitable manner but I prefer to provide a
box or receptacle to contain suet which discharges melted fat downward upon the
gudgeon.
The gland is set up by a screw passing through a cap and to make a joint
between this cap and the standard I form an annular channel in the face of the
standard or on the back of the cap and I fill this channel with lead or pewter or
with a suitable alloy or with asbestos or with a packing ring of suitable material
and I form a narrow edged ring upon the cap or upon the standard as the case may
be, the edge of such ring being pressed against the packing when the cap is tightly
secured by means of bolts or screws.

Improvements in Supports for Drying Cylinders.
I JOSEPH JOHNSON SUMNER, of Bank View, Furness Vale, near Stockport,
in the County of Chester, Mechanic, 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 and accompanying drawings:
My invention relates to the standards or pedestals which sustain the cylinders

stuffing boxes and with means for supplying steam to the cylinders. As ordinarily
constructed the upper end of each standard is adapted to receive the gudgeon of
the cylinder and is provided with an adjustable gland and with packing in which
the said gudgeon revolves.
As the drying cylinder is comparatively heavy, the gudgeon tends to wear the
lower side of the bearing which sustains the weight so that in course of time the
axis of the gudgeon is lowered and does not coincide with the axis of the gland
and bearing.
To remedy this defect I provide the stand end with an adjustable bearing which
sustains the weight and which can be raised whenever desirable so as to restore
the axis of the gudgeon to its proper working level.
The said bearing may consist of a half step of brass or other suitable metal or
alloy seated in a recess in front of the stuffing box and fitted to slide vertically.
The adjustment may be effected by means of a screw or of a cottar or by other
suitable means.
A passage is formed to permit of the escape of water between
the stuffing box and the bearing so as to check the passage of water to the bearing.
It may not be necessary to bore the head of the standard to receive the gudgeon.
The bearing may be lubricated in any suitable manner but I prefer to provide a
box or receptacle to contain suet which discharges melted fat downward upon the
gudgeon.
The gland is set up by a screw passing through a cap and to make a joint
between this cap and the standard I form an annular channel in the face of the
standard or on the back of the cap and 1 fill this channel with lead or pewter or
with a suitable alloy or with asbestos or with a packing ring of suitable material
and I form a narrow edged ring upon the cap or upon the standard as the case
may be, the edge of such ring being pressed against the packing when the cap is
tightly secured by means of bolts or screws.
To render my invention clearly understood I will now proceed more clearly to
describe and ascertain the same, reference being had to the annexed sheet of
drawings.
Fig. 1 is a sectional view of a standard or support for carrying the gudgeon of a
drying cylinder.
Fig. 2 is a front view of the standard with the gudgeon withdrawn.
Fig. 3 is a plan view of the standard.
Figs. 4, 5 and 6 show modifications of the methods of raising or adjusting the
bearing.
The standard is marked A and is hollow so as to allow of the passage of steam
or other heating fluid to the drying cylinder. The upper end or boss 7 of the
standard is formed with an extension adapted to receive the half step bearing c.
It will be noted that the half bearing c at that end which comes against the boss b,
is formed with a recess which constitutes a space between the end of the
boss 6 and the half bearing c. This space acts as a trap to arrest any water or
condensed steam which may pass the gland, and prevent it from finding its way to
the half bearing c. Thus a great source of grinding and rapid wearing of the
half bearing is avoided. I bore a hole a in the extension at the bottom of the
recess to allow the arrested water to go free. The half bearing c, is machined to
fit the hollow turned gudgeon d of the drying cylinder, the gudgeon also
projecting into the packed gland in the boss b as clearly shown in Fig 1.
To keep the half bearing c well lubricated, I arrange a box e above the bearing,
which box contains suet or other suitable solid lubricant which is melted by the
heat of the gudgeon so as to maintain a sufficient supply of the lubricating agent
to the bearing. As has already been pointed out, the tendency of the revolving
gudgeon is to wear the lower side of the bearing c so that in course of time the
axis of the gudgeon and drying cylinder becomes lowered. I therefore make the
half bearing adjustable vertically, so that such wear can be compensated for and
made good. The half bearing c slides vertically in the extension block 6, and

page_text: beneath the half bearing c I place an adjusting screw f, by turning which the
bearing c can be raised or lowered. The upper end or boss b of the standard,
comprises the stuffing gland which is usual in standards of this description. The
packing g and the ring for compressing the packing are introduced through the
opposite end of the boss from the gudgeon end. The ring his set up so as to
compress the packing by a screw passing through a cap j. To form a joint
between this cap and the end of the boss, I form an annular channel in the boss
end and fill it with soft metal or alloy k or other suitable material such as asbestos.
I also form the cap with a narrow edged ring the edge of the ring pressing
against the packing k when the cap is secured to the standard by bolts m m as
clearly shown in Figs. 2 and 3. It will of course be evident that this arrangement
might be reversed, and the soft metal or other packing ring be run into the cap,
whilst the projecting edge would be formed upon the end of the boss.
I have referred to the half bearing c as being most conveniently adjusted by a
vertical screw, but of course it will be evident to any person of mechanical
training that more than one method of so adjusting the half might be adopted.
For example in Fig. 4 a sliding wedge o placed beneath the bearing and drawn
forward by means of a nut p might be used, and this wedge o might be arranged
either as in Fig. 4 with its inclined face against the extension block, or vice versa
as in Fig. 5. The same arrangement of a wedge might be used as in Fig. 6, viz.
with the wedge o mounted on a screw q which is turned so as to move the wedge
backward and forward, and thus raise or lower the half bearing c. Even these
examples do not however exhaust the means which might conveniently be used to
adjust the bearing c or its equivalent.
It will be observed that it is not necessary to bore or machine any part of the
standard A except in so far as relates to boring or tapping the hole to receive the
adjusting screw. The gudgeon may pass through a clearing hole which may be
cast to the requisite size.
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.
1. The improved standard or support for use in conjunction with drying
cylinders and having applied to or used in conjunction therewith one or the whole of
the various novel features set forth in the foregoing Specification, namely the means
for adjusting the bearing of the gudgeon; the means for trapping and getting rid
of the steam or condensed water from the stuffing gland; and the method of
effecting a fluid tight joint between the back-centre cap and the standard,
substantially as hereinbefore described and shown.
2. As an adjunct to or part of standards or supports for drying cylinders, the
provision of meaus for adjusting the bearings of the gudgeons of the cylinders so as
to compensate for wear substantially as described and as shown.
3. In standards or supports for drying cylinders the recess or space for
trapping and removing the leakage from the stuffing box so as to prevent the said
leakage from reaching the bearing, substantially as described and illustrated.
4. As means for effecting a fluid tight joint between the back cap and the
standard, providing a sunk annular ring of soft metal or other suitable material in
the standard or in the cap, and forming a corresponding projecting annular lip or
ring on the cap or on the standard substantially as described and shown.
