Improvements in Road Rollers.
1, WILLIAM PENROSE GREEN, of the firm of Thomas Green & Son Limited
Smithfield Iron Works, Leeds, in the County of York, Engineers, do hereby
declare the nature of this invention to be as follows:-
This invention relates to certain improvements whereby time and money are
saved in the necessary repairs of the rollers of steam road rollers.
Hitherto the rollers, which also form the wheels of steam road rollers, have been
constructed in one piece, that is to say, the boss, the arms and the rim have formed
one structure. The wear and tear is greatest upon the rim, which needs from time
to time renewing as hitherto constructed such renewal has involved the renewal
of the entire wheel or roller.
:
By my improvement I so construct the roller or wheel, in the first instance, as to
admit of the renewal of the rim without any loss of time, and a continued utilizing
of the other parts of the structure, such as the boss and arms, rendered useless by
the mode of construction hitherto.
In order to accomplish my object, I construct the roller or wheel of such form,
that the outer rim when worn may be readily detached and a new one attached by
the ordinary attendant of any steam roller.
The rim is prepared to receive such outer rim in the first instance by turning
the same to gauge, the outer rim is turned out to fit the same and by means of
bolts passing through the inner and outer rim, the latter is firmly secured to the
former.
The belts between the arms are set out to one uniform gauge, and on a new outer
rim being required, the same can be ordered and sent and attached at the
convenience of the owner, and without the loss of time involved in such repairs as
when hitherto constructed.
Preparation is also made for the introduction of the spikes for breaking up the
roads as hitherto in use.

COMPLETE SPECIFICATION.
Improvements in Road Rollers.
I, WILLIAM PENROSE GREEN, of the firm of Thomas Green & Son Limited,
Smithfield Iron Works, Leeds, in the County of York, 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 certain improvements whereby time and money are
saved in the necessary repairs to the rollers of steam road rollers.
Hitherto the rollers which also form the wheels of steam road rollers, have been
constructed in one piece, that is to say, the boss, the arms and the rim have formed
one structure. The wear and tear is greatest upon the rim which needs from time
to time renewing: as hitherto constructed such renewal has involved the renewal
of the entire wheel or roller.
By my improvement I construct the roller or wheel, in the first instance as to
admit of the renewal of the rim without loss of time, and a continued utilizing of

page_text: the other parts of the structure such as the boss and arms rendered useless by the
mode of construction as hitherto.
In the accompanying drawings
Fig. 1 represents a side elevation of a road roller constructed according to my
invention, and
Fig. 2 is a transverse vertical sectional elevation through the centre of the same.
I construct the roller or wheel of such form that the outer rim A when worn
may be readily detached and a new one attached by the ordinary attendant of any
steam road roller.
The inner rim B is prepared to receive the outer rim A in the first instance by
turning the same on face C to the diameter of a standard gauge and also on the
surface D, the outer rim A. is turned to fit the same and by means of bolts E
passing through the inner rim B. and internal flange A¹ of outer rim A. the latter
is firmly secured.
The pitch of the bolts E is set out to one uniform gauge, and on a new outer
rim A, being required, the same can be ordered, turned to the standard gauge to
fit the inner rim B. and bored for the reception of the bolts, and when delivered
may be attached at the convenience of the owner without the loss of time involved
in such repairs when the rollers are constructed as hitherto.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
Road rollers constructed with an inner rim B turned on the face C to a standard
gauge diameter, and encircled by a detachable rim A all constructed and attached
substantially in the manner as hereinbefore described and illustrated by the
accompanying drawings.
