Improvements in Cylinder Ends and in the Mode of Securing the
same to Steam Heated and other Cylinders.
I HENRY BERNOULLI BARLOW of 17 St. Anns Square Manchester in the County
of Lancaster Consulting Engineer do hereby declare the nature of said Invention for
IMPROVEMENTS IN CYLINDER ENDS AND IN THE MODE OF SECURING THE SAME TO
STEAM HEATED AND OTHER CYLINDERS, to be as follows:-
My invention is particularly applicable to sheet metal cylinders having cast or other
metal ends my object being to dispense with the use of solder and rivets to avoid the
necessity of coneing the ends of the cylinder and to connect the ends to the cylinder
in a simple manner so that a steam tight joint may be ensured and so that the ends
may be readily disconnected when desirable.
In performing my Invention I use for each end or for one end only of the cylinder
a disc which may have a solid or hollow central boss to constitute a bearing and near
the periphery an annular groove is formed the outer side of which fits over the end of
the cylinder the inner side of the groove being taper I make a ring of corresponding
shape the outer cylindrical part of which fits against the inner surface of the end of
the sheet metal cylinder and the inner taper surface of which bears against the taper
surface of the annular groove. This ring forms a wedge and it is cut through at one
point it is connected to the disc by screws or bolts which pass through the disc and
enter the narrow end of the ring and when tightened draw the ring into the recess
thus causing the end of the cylinder to be gripped firmly between the outer side of
the ring and the disc and ensuring a steam tight joint. When the screws or bolts
have been loosened the end disc may be instantly removed from the cylinder.
The split ring may be cut transversely partly through in several places or
segmental wedges may be employed in place of a ring.
Instead of sheet metal cylinders solid drawn tubes or other cylinders may have
my improved ends applied them and where much pressure has to be carried by the
cylinders longitudinal bolts passing through both discs may be employed.

page_text: A ring of asbestos or other packing may be placed in the annular groove for the
end of the cylinder to bear against.
Great economy is secured by the use of my Invention the use of solder and the
necessity for coneing the ends of the cylinders are avoided and the greatest facility is
afforded for the removal of the ends of the cylinders for repairs or for inserting
linings or for other purposes.
I have described the split ring or its equivalent placed inside the cylinder it is
obvious it might be placed outside by increasing the diameter of the disce and forming
the annular groove to suit the altered position of the ring.
same to Steam Heated and other Cylinders.
I HENRY BERNOULLI BARLOW of 17 St. Ann's Square Manchester in the County
of Lancaster Consulting 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 invention is particularly applicable to sheet metal cylinders having cast or
.other metal ends my object being to dispense with the use of solder and rivets to
avoid the necessity of coneing the ends of the cylinder and to connect the ends to the
cylinder in a simple manner so that a steam tight joint may be ensured and so that
the ends may be readily disconnected when desirable.
In performing my Invention I use for each end or for one end only of the cylinder
a disc which may have a solid or hollow central boss to constitute a bearing and near
the pheriphery an annular groove is formed the outer side of which fits over the end
of the cylinder the inner side of the groove being taper I make a ring of corresponding
shape the outer cylindrical part of which fits against the inner surface of the end of
the sheet metal cylinder and the inner taper surface of which bears against the taper
surface of the annular groove. This ring forms a wedge and it is cut through at one
point it is connected to the disc by screws or bolts which pass through the disc and
enter the narrow end of the ring and when tightened draw the ring into the recess
thus causing the end of the cylinder to be gripped firmly between the outer side of

have been loosened the end disc may be instantly removed from the cylinder.
The split ring may be cut transversely partly through in several places or segmental
wedges may be employed in place of a ring.
Instead of sheet metal cylinders solid drawn tubes or other cylinders may have my
improved ends applied to them and where much pressure has to be carried by the
cylinders longitudinal bolts passing through both discs may be employed.
A ring of asbestos or other packing may be placed in the annular groove for the
end of the cylinder to bear against.
And in order that my Invention may be fully understood and readily carried into
effect I will describe the accompanying two sheets of Drawings reference being had
to the figures and letters marked thereon.
Fig. 1 is a side view in section of one end of a sheet metal cylinder to which my
improvements are applied and Fig. 2 is one outside view of the same. Figs. 3 and 4
are two views of a split ring which I employ according to my Invention Figs. 5,
6 and 7 are sectional views of parts of cylinder ends illustrating slight modifications
in my Invention and Fig. 8 is a front view looking on the inside of a cylinder end
showing the shell in section.
In Figs. 1 and 2.-A designates the shell of a drying cylinder; one end or disc
for the same in this case made with a hole through its central boss for the purpose
of admitting steam to the cylinder near the periphery of the end is an annular
groove 6 the outer side of which fits over the shell a and the inner side of which is
tapered; a ring e corresponding in shape with the groove band of suitable diameter
is fitted therein so that its outer cylindrical part bears against the inner surface of
the shell a and the inner taper surface bears upon the taper surface of the groove b¹.
The ring c is cut complely through in one place and may be partially cut through
in several places as shown in Figs. 3 and 4, so that when in its position it forms a
circular wedge capable of expansion when drawn towards the end b by screws d which
have washers e and thus grip the shell a firmly in position and make a steam tight
joint.
In Fig. 5 is shown part of a sheet metal end 6 for a steam drying cylinder to which
is secured by rivets 62 or otherwise a ring of metal f provided with an annular
groove the split ring c being used as before for forming a steam tight joint between
the shell a and ring. In this case the outer side of the groove is turned hollow at f2
and the ring c is turned slightly convex at c² in order to increase the grip on the
shell a.
In Fig. 6 part of a cylinder end is shown made of cast or sheet metal to which
an outer ring g with an annular groove g¹ and flange g² is bolted by bolts the split
ring c being used as before to form a steam tight joint. The groove g² and the ring c
are formed to bend the shell slightly when the screws d are tightened.
Fig. 7 shows the split ring placed outside the shell a instead of inside it as in
Figs. 1 and 2.
Fig. 8 is a sectional front view of a cylinder end in which a number of sectional
wedges are employed in place of the split ring c.
Cylinders fitted with these improved ends as herein described and illustrated dispense
with the operation of concing or flanging the shell a at the ends as now practised by
some makers thereby avoiding the risk of damage to the metal and saving the time
employed in such coneing or flanging whenever the ends are put on or removed and
further as the shell is not contracted at the ends, there is no difficulty in placing the
buckets or in removing them from the cylinder as required.
By simply slackening the screws d either cylinder end can be removed without the
necessity for detaching the split ring for repairing or examining the interior, after
which the end band ring e screwed together are ready to be pushed on to the shell a
of the cylinder when it is only necessary to tighten the screws to make a steam
tight joint.
If desired a plate can be secured at one end to the ring in order to cover the slit
where the ring is divided.

page_text: Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what I
claim is―
1. The improved mode of securing metal ends to sheet metal drying cylinders
substantially in the manner and by the means herein shown and described.
2. A cylinder each metal end of which has an annular groove formed with one
taper side combined with a split ring or wedges fitted in said groove and secured by
thread screws or equivalents to form a steam tight joint between the shell and end of
the cylinder as herein set forth.
3. The several constructions combinations and arrangements of parts embodying
my improvements in attaching metal ends to cylinders substantially as and for the
purposes herein described and as shown.
