Improvements in and relating to Road Rollers.
I, JAMES MACMILLAN CUTHBERT, of 26, Maxwell Street, Dalbeattie, Kirkcudbright-
shire, Road Surveyor, do hereby declare the nature of my invention to be as
follows:-
This invention has reference to improvements in and relating to road rollers, and
essentially consists in constructing said rollers with alternate grooves and projecting
surfaces, so as to act as combined disintegrators and rollers, that is, the diminished
area of contact increases the power of the rolling surface of the roller, and forces the
new metal into the joints in the old and the open grooves on the roller, by removing
resistance facilitates the disintegration of the old surface by providing open spaces
into which the displaced materials may freely rise, and by repeated rollings the old
and new materials become incorporated.
The grooves may be formed parallelly round the roller, or longitudinally, spirally,
or otherwise.

I, JAMES MACMILLAN CUTHBERT, of 26, Maxwell Street, Dalbeattie, Kirkcudbright-
shire, Road Surveyor, do hereby declare the nature of my invention and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement, that is to say :--
This invention has reference to improvements in and relating to road rollers, and
essentially consists in constructing said rollers with alternate grooves and projecting
surfaces, so as to act as combined disintegrators and rollers, that is, the diminished
area of contact increases the power of the rolling surface of the roller, and forces the

removing resistance facilitates the disintegration of the old surface by providing open
spaces into which the displaced materials may freely rise, and by repeated rollings
the old and new materials become incorporated.
And in order that my said invention and the manner of carrying same into prac-
tice may be properly understood, I have hereunto appended a sheet of explanatory
drawings, in which the same reference letters are used to indicate corresponding
parts in all the figures where shown. Figure 1 is a front elevation showing a duplex

diagonally, and those of the one roller converge or fit into those of the other roller.
Figure 2 is a similar view of a roller in which the grooves a and projecting surfaces b
are arranged parallelly and circumferentially round the roller. In Figure 3 the
grooves a are formed longitudinally on the roller.
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
The constructing of road rollers in the improved manner herein described in
reference to and shown in the accompanying drawings.
