We, GEORGE BENTLEY and JOHN BROAD JACKSON both of Lodge Bank Works
Bury in the County of Lancaster Engineers and JOHN MAONAREY, Manager at the
said Works do hereby declare the nature of this Invention to be as follows:--
Our Invention relates to the construction of cylinders or drums by means such as
are described in the Specification of Letters Patent No. 1316 dated 3rd May 1872
granted to Daniel Bentley and one of us namely me the said John Broad Jackson and
our said Invention has for its object to obviate the defect incidental to the con-
struction as described and illustrated by the Specification of the said Letters Patent
consisting in the drawing inwards of the periphery of the cylinder or drum at portions
a little from the ends due to the pressure put on the bolts or fastenings.
According to our present invention we make the flanges, projections, snugs or the
like which are respectively formed on the inside of the cylinder or drum and the end
disc so that they abut firmly against each other and make a joint around the inside
of the cylinder preferably extending from the line of the inner periphery of the
cylinder or drum continuously to the tops of the snugs or the like in which the
fastenings are placed and when the fastenings are screwed up or otherwise fastened
the joint formed by the abutting of the meeting faces as aforesaid prevents the
herein before mentioned contortion of the cylinder or drum. The joint is preferably
turned on the meeting faces and it may in addition or in substitution he cemented.
On the snugs on the cylinder are preferably cast projections which enclose or partly
enclose the washers used with the fastenings and keep them in place when the
fastening bolts and nuts are being screwed up. They will also prevent the bolts
from falling out should the nuts become slack.

We, GEORGE BENTLEY and JOHN BROAD JACKSON, both of Lodge Bank Works
Bury in the County of Lancaster, Engineers, and JOHN MACNAREY, Manager at the
said Works 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:-
This Invention relates to the construction of cylinders or drums by means such as
are described in the Specification of Letters Patent No. 1346 dated 3rd May 1872
granted to Daniel Bentley and one of us namely me the said John Broad Jackson
and our present Invention has for its principal object to obviate the defect incidental
to the construction as described and illustrated by the Specification of the said Letters
Patent consisting in distortion of the cylinder or drum by the drawing inwards of the
periphery of the said cylinder or drun at portions a little from the ends due to the
pressure put on the bolts or fastenings owing to the space between the lugs marked A
in the drawings accompanying the Specification of the said Patent No. 1346 of 1872
and the projections with the T slots on the end disc.
Figure 1 of the accompanying drawings represents an end view of a cylinder or
drum one half being shewn with the end plate or disc in place and the other half
being shewn without the end plate or disc. Figure 2 is a side view partly in
longitudinal section. Figure 3 is a section shewing the inside of one of the end
plates or discs and Figures 4 and 5 are enlarged sectional details illustrating the
present Invention according to which we make the flanges projections snugs or the
like marked A and D which are respectively formed on the inside of the cylinder or
drum B and the end plates or dises so that the said flanges projections snugs or the
like abut firmly against each other and make joints around the inside of the cylinder
preferably extending where the fastenings occur from the line of the inner periphery
of the cylinder or drum B continuously to the tops of the snugs or the like A and D
in which the said fastenings are placed and when the fastenings (such as the bolts a)
are screwed up or otherwise fastened the bearing of the joints formed by the abutting
of the meeting faces of the parts A and D as aforesaid prevent the hereinbefore
mentioned distortion of the cylinder or drum B. The joints are preferably turned on
the meeting faces and they may in addition or in substitution be cemented. On the
snugs A on the cylinder are preferably cast projections a³ which enclose or partly
enclose the washers and the nuts used with the fastenings and keep the bolts a in
place should the nuts become slack. Instead of the projections A having deep
recesses between them they may constitute a continuous flange or nearly continuous
flange to give an extended bearing on D. This is indicated at Figure 1.

page_text: Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is.
In cylinders or drums for paper making or other machines joints between the
Cylinder and discs or ends made by the flanges projections snugs or the like on
the Cylinder and dises or ends respectively having bearings or joints extending as
described whether the joints be cemented or not and whether or not the projections a²
be provided all substantially as hereinbefore described and illustrated in the accom-
panying drawings.
