We, THOMAS PERKINS and JOHN EDWARD SHARMAN PERKINS both of Queen
Street Peterborough Engineers do hereby declare the nature of this invention to be
as follows:-
:-
This Invention relates to improvements in rollers for rolling land and consists in
improved ways of constructing rollers adapted to be loaded with sand water or other
ballast for the purpose of adding to the weight.
We form the roller cylinder of a circular trough provided with a cover which rests
upon a flange cast within the trough and is secured by bolts. A gudgeon or stud to
serve as an axis is cast upon the bottom of the trough in the centre thereof and a
corresponding gudgeon or stud is cast upon the cover. Or these gudgeons or studs
may be bolted or otherwise fixed upon the bottom and cover respectively. Or a
central hole may be formed in the bottom of the trough and a corresponding hole in
the cover.
A wrought iron tube is inserted through these holes and fixed securely.
An axle is passed through the tube and its ends support the frame of the roller.
Or in place of fixing the wrough iron tube into the holes in the bottom of the trough
and in the cover; wrought iron rings may be secured to the trough and to the cover
around the holes and the tube may be fixed into these rings. Or the tube may be
cast with the roller cylinder which then takes the form of an annular trough. The
trough receives a cover having a hole in the centre and the cover is supported all
round its edges on flanges cast within the trough and upon the central tube.
Or the tube may be cast with the cover in place of with the trough like roller
cylinder, the flange at the end of the tube then comes against the bottom of the
trough around the hole therein and is secured to it by bolts. Or the hole in the
bottom of the trough may be made large enough to admit the flanged end of the tube.
A ring is then applied on the outside and is secured by bolts both to the flange of the
tube and to the bottom of the trough.
The cover in some cases may be made considerably smaller in diameter than the
cylinder to which it is applied, a corresponding extension being given to the flange
on which the cover rests.
The constructions above described result in the two ends of the roller cylinder
being dissimilar they admit however of being varied so that the cylinder may have
similar ends.

page_text: We, THOMAS PERKINS and JOHN EDWARD SHARMAN PERKINS both of Queen
Street, Peterborough, Engineers, 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 improvements in rollers for rolling land and consists in
improved ways of constructing rollers adapted to be loaded with sand water or other
ballast for the purpose of adding to the weight.
We form the roller cylinder of a circular trough provided with a cover which rests
upon a flange cast within the trough and is secured by bolts. A gudgeon or stud to
serve as an axis is cast upon the bottom of the trough in the centre thereof and a
corresponding gudgeon or stud is cast upon the cover.
Figure 1 shows a roller constructed in this manner- being the trough and 6 the
cover resting upon the flange al around the trough and being secured to it by bolts
which, in this and the other figures are not shown-c, c, are gudgeons or studs to
serve as an axis to the roller.
Or these gudgeons or studs may be made separately and bolted upon the bottom
and cover respectively or upon the bottom, as shown in Figure 2.
Or they may be fixed in other ways, for example, they may form the ends of a
through axis secured by a screw and nut d, as shewn in Figure 3.
Or a central hole may be formed in the bottom of the trough and a corresponding
hole in the cover. A tube is inserted through these holes and fixed securely.
An axle is passed through the tube and its ends support the frame of the roller.
Figure 4 shows this arrangement-a being the trough and 6 the cover as before-e is
the tube which is secured at its ends by ferrules expanded into it-These ferrules
form the bearings for the axle.
Or in place of fixing the tube into the holes in the bottom of the trough and in
the cover; wrought iron rings may be secured to the trough and to the cover around
the holes and the tube may be fixed into these. rings. Figure 5 shows this arrange-
ment a, a, being the trough and the cover-e the tube-f, f, the ferrules and 9, 9,
the plates into which the tube is expanded. Or the tube may be cast with the roller
cylinder which then takes the form of an annular trough. The trough receives a
cover having a hole in the centre and the cover is supported all round its edges
on flanges cast within the trough and upon the central tube. Figure 6 shows this
arrangement a, a, is the trough and tube cast in one-b is the cover which is secured
to the flanges a¹, a², on the trough and tube.
Or the tube may be cast with the cover in place of with the trough like roller
cylinder, the flange at the end of the tube then comes against the bottom of the
trough around the hole therein and is secured to it by bolts.
Figure 7 shows this arrangement-the cover and tube b are made in one piece,
the flange bl of the tube is bolted to the bottom of the trough. Or the hole in the

page_text: bottom of the trough may he made large enough to admit the flanged end of the tube.
A ring is then applied on the outside and is secured by bolts both to the flange of the
tube and to the bottom of the trough.
Figures 8, 9, and 10 illustrate this arrangement-In Figures 8 and 9 the ring g is
bolted to the flange of the tube and to the bottom of the trough a, and in Figure 10
the flange on the tube is dispensed with and the ring g assumes the form of a nut
screwing on to a thread at the end of the tube.
on which
In Figure 9, the cover is made considerably smaller in diameter than the cylinder
to which it is applied a corresponding extension being given to the flange
the cover rests, and this modification is obviously applicable to the other figures.
The constructions above described result in the two ends of the roller cylinder
being dissimilar they admit however of being varied so that the cylinder may have
similar ends.
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
1. A roller cylinder consisting of a circular trough provided with a cover resting
upon and secured to a flange formed within the trough substantially as described.
2. Our improvements in machinery for rolling roads and other surfaces substantially
as described.
