Improvements in Land or Garden Rollers.
We THOMAS POSTLETHWAITE of 70 Beaconsfield Street, Princes Road, Liverpool,
Salesman, and ROBERT SMITH and SHEM PAGET both of Parker Street Iron Works,
Keighley, in the county of York, Machine Makers, do hereby declare the nature of
this invention to be as follows:-
This invention for Improvements in Land or Garden rollers relates to rollers of
that class in which the weight of the roller can be varied within certain limits at
pleasure by being filled with water, or sand, or any other suitable ballast.
The object of this invention is to provide improved means for securing the body or
main barrel of the roller to its centre, so that the two ends may be rigidly secured
and stiffened, and the joints releived of any excessive strain tending to break them or
to produce leaking of the ballast; and to provide suitable bearings for the axle or
spindle passing through the said centre.
In carrying out our invention, we construct each roller of a hollow cylindrical form
with flat ends, and in the axis of the said cylinder we place a hollow bush, or tube,
or sleeve, formed with a flange at either end and with suitable projecting fitting rings
or collars. One of the said flanges is considerably. smaller than the other, so that it
can readily be passed through the hole in one of the flat ends of the body of the
roller and secured to the other end. The distance from face to face of the said flanges
is equal to the distance from the inside of one end to the outside of the other end of
the roller, so that the two flanges may be rigidly secured to the said ends, one on the
inside of one, and the other on the outside of the other. When the roller is con-
structed of cast iron the periphery of the smaller flange of the sleeve fits into a ring
on the inside of the corresponding end of the roller, while the opposite end of the
roller is recessed so as to receive the larger flange of the sleeve. By these means the
ends are rendered flush and compact, and the joints more effectively secured, while
the pressure between the sleeve and the roller is resisted by the periphery of the.
joining flanges, thus distributing the said pressure over a large surface.

page_text: The inside of the sleeve is cored out in its central part leaving a suitable length at
each end for the purpose of forming a bearing for the axle or spindle.
The ballast is inserted into the roller through a hole in its periphery, the said hole
being normally closed by means of a screwed plug.
It will be obvious that any convenient number of separate rollers may be mounted
on one shaft or spindle.

We THOMAS POSTLETHWAITE of 70 Beaconsfield Street, Princes Road Liverpool,
Salesman, and ROBERT SMITH and SHEM PAGET both of Parker Street Iron Works,
Keighley, in the county of York, Machine Makers, 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 for Improvements in Land or Garden Rollers relates to rollers of
that class in which the weight of the roller can be varied within certain limits at
pleasure by being filled with water or sand or any other suitable ballast.
The object of this invention is to provide improved means for securing the body or
main barrel of the roller to its centre so that the two ends may be rigidly secured
and stiffened and the joints releived of any excessive strain tending to break them or
to produce leaking of the ballast, and to provide suitable bearings for the axle or
spindle passing through the said centre.
In carrying out our invention we construct each roller of a hollow cylindrical form
with flat ends, and in the axis of the said cylinder we place a hollow bush or tube,
or sleeve, formed with a flange at each end to fit into suitable fitting rings or recesses
in the roller ends. One of the said flanges is considerably smaller than the other, so
that it can readily be passed through the hole in one of the flat ends of the body of
the roller and secured to the other end. The distance from face to face of the said
flanges is equal to the distance from the inside of one end to the outside of the other
end of the roller, so that the two flanges may be rigidly secured to the said ends,
one on the inside of one, and the other on the outside of the other. When the roller
is constructed of cast iron the periphery of the smaller flange of the sleeve fits into
a ring on the inside of the corresponding end of the roller, while the opposite end of

page_text: the roller is recessed so as to receive the larger flange of the sleeve. By these means the
ends are rendered flush and compact and the joints more effectively secure, whilst
the bearing pressure between the sleeve and the roller is resisted by the periphery
of the joining flanges, thus distributing the said pressure over a large surface.
In the accompanying sheet of illustrative drawings Figs. 1 and 2 represent
respectively a side elevation and a horizontal section of a two cylinder land or garden
roller constructed according to our invention.
Each cylindrical roller a is constructed with flat ends bc the outer end 6 being pro-
vided with a fitting ring or collar d whilst the inner end c is recessed at eas clearly
shewn. A hollow bush or sleeve with flanges g h is secured to the said ends be
the hole in the end being large enough to permit of the flange g being passed
through it and secured to the inside of the end b, whilst the flange h is secured to
the outside of the end c.
c
The sleeves fare cored out at i leaving a suitable length at each end for the purpose
of forming a bearing for the axle k.
Balance weights
are secured to the ends of the axle k and to the ends m of the
frame n as clearly shewn.
The ballast is inserted into the roller through a hole in its periphery, the said hole
being normally closed by means of a screwed plug.
It will be obvious that any convenient number of separate rollers may be mounted
on one shaft or spindle.
Figs. 3 and 4 represent in vertical and horizontal section a modified form of a
two cylinder roller in which, instead of the two balance weights shewn in
Figs. 1 and 2, we employ one central weight o secured to the centre of the axle k,
the cylinder being set back as clearly shewn.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In Land or Garden Rollers: constructing each cylinder with a central hollow
bush or sleeve provided with flanges of unequal diameters fitting in collars or
recesses in the cylinder ends, one flange of the said sleeve being secured to the inside
of one cylinder end whilst the other is secured to the outside of the opposite end
substantially as described.
2. The arrangement and construction of Land or Garden Rollers substantially as
described with reference to the drawings.
