Collieries, Quarries, and for other Purposes.
I JOSEPH WILKES of Pelsall Foundry near Wallsall in the County of Stafford
Engineer and Ironfounder do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN TRAMWAY OR ROPE ROLLERS OR PULLEYS FOR COLLIERIES
QUARRIES AND FOR OTHER PURPOSES to be as follows:-
"
My invention consists in constructing tramway or rope rollers or pulleys for
collieries quarries and for other purposes in the manner hereinafter described
whereby they are made more efficient in action and are less costly than ordinary
rope rollers or pulleys and the separable caps ordinarily used on the bearings are
dispensed with.
The ordinary tramway or rope roller or pulley consists of a frame or box
provided at each side with a bearing into which the ends of the spindle of the
roller are dropped and in which they rotate the tops of the bearings in the
frame or box being covered by loose or separable caps fixed in their places by pegs
or hinges.
In constructing the said rollers or pulleys according to my invention I form the
bearings in which the ends of the spindle of the roller or pulley work separate
from the frame or box and I form in opposite sides of the frame or box seats
for receiving the said separate bearings The said separate bearings consist of
cylindrical blocks having cross holes in them in which holes the ends of the roller
spindle engage and work. The top of the separate bearing is expanded and forms
a cap or cover for closing the top of the seat in the frame or box. An axial hole
passing from the top of the cap or cover of the bearing communicates with the
cross hole in the bearing in which the end of the roller spindle works and through
the said axial hole the lubricant is passed for lubricating the said spindle.. The
inner side of the cap or cover is flattened and bears against a bush on the spindle
of the roller. The cylindrical part of the bearing fits in a cylindrical seat the
bearing having a little play therein. By this means the bearings can adapt them-
selves to the slight angular motion which the roller or pulley takes when in use.

page_text: In fitting the box or frame with the roller or pulley the detachable bearings are
placed upon the ends of the roller spindle and the roller carrying the bearings is
lowered into its box or frame and the bearings made to seat themselves in the seats
at the sides of the said frame the seats being covered by the caps or expanded ends
of the bearings. The roller or pulley is thus ready for use the fixing of the
separable caps as ordinarily required being dispensed with.
By my invention the roller or pulley can be quickly removed from and replaced
in the fixed frame or box and the bearings when worn can be readily renewed.

I JOSEPH WILKES of Pelsall Foundry near Walsall in the County of Stafford
Engineer and Ironfounder 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:—
My invention consists in constructing tramway or rope rollers or pulleys for
collieries quarries and for other purposes in the manner herein after described,
whereby they are made more efficient in action and are less costly than ordinary
rope rollers or pulleys and the separable caps ordinarily used on the bearings are
dispensed with.
The ordinary tramway or rope roller or pulley consists of a frame or box
provided at each side with a bearing into which the ends of the spindle of the
roller are dropped and in which they rotate, the tops of the bearings in the frame
or box being covered by loose or separable caps fixed in their places by pegs.or
hinges.
In constructing the said rollers or pulleys according to my invention, I form the
bearings in which the ends of the spindle of the roller or pulley work separate
from the frame or box and I form in opposite sides or ends of the frame or box
seats for receiving the said separate bearings. The said separate bearings consist
of cylindrical blocks having cross holes in them in which holes the ends of the
roller spindle engage and work. The top of the separate bearing is expanded and
forms a cap or cover for closing the top of the seat in the frame or box. An axial
hole passing from the top of the cap or cover of the bearing communicates with
the cross hole in the bearing in which the end of the roller spindle works and
through the said axial hole the lubricant is passed for lubricating the said spindle
The inner side of the cap or cover and bearing is flattened and bears against a bush
on the roller.
The cylindrical part of the bearing fits in a cylindrical seat the bearing having
a little play therein. By this means the bearings can adapt themselves to the
slight angular motion which the roller or pulley takes when in use.
Figure 1 of the accompanying Drawings represents in side elevation; Figure 2
in plan; Figure 3 in longitudinal vertical section and Figure 4 in end elevation, a
tramway or rope roller or pulley constructed according to my invention; Figure 5
represents in side elevation the roller or pulley detached from the box or frame one
of the separable bearings being represented on the roller spindle; Figures 6 and 7
represent elevations of one of the separable bearings, the said elevations being
taken at right angles to one another and Figure 8 represents in plan the box or
frame and its bearing seats without the roller or pulley.

The same letters of reference indicate the same parts in the several Figures of
the drawings.
a is the roller or pulley over which the tramway or other rope works and b is the
frame or box, in which the said roller or pulley is fitted and rotates the flanges of

separable bearings in which the ends of the spindle e of the roller or pulley a work
and f, fare seats on opposite sides or ends of the frame or box b for receiving the
said separable bearings d d. Each of the said separable bearings d, d consists of a
cylindrical block with a flattened inner face and each of the seats f has a corre-
sponding figure. In the said bearings d, d, cross holes g, g are made in which the
ends of the roller spindle e engage and work as seen in the longitudinal section
Figure 3: h is an axial hole in the cylindrical bearing d communicating with the
cross hole g in which the end of the roller spindle works.
The
Through the axial hole the lubricant is passed for lubricating the spindle e (see
Figure 3); d is the expanded top of the bearing d the said top forming a cap or
covering for closing the top of the cylindrical seat f. The flattened inner face of
the bearing d is situated nearly in contact with the bush a' on the roller a.
cylindrical part of the bearing d fits loosely in the cylindrical seat f so that the
said bearing has a little play therein The bearings d d can by this means adapt
themselves to the slight angular motion which the roller or pulley a takes when
in use.
In fitting the box or frame b with the roller or pulley a the detachable or
separable bearings d d are placed upon the ends of the roller spindle e and the
roller carrying the bearings is lowered into its box or frame b and the said
bearings d made to seat themselves in the seats f at the sides or ends of the said
frame b, the seats f being covered by the caps or expanded ends d³ of the bearings d
the said bearings d being supported or suspended by the said caps d² resting on the
tops of the seats f. The roller or pulley a is thus ready for use, the fixing of the
separable caps as ordinarily required being dispensed with.
By my invention the roller or pulley can be quickly removed from and replaced
in the fixed frame or box and the bearings when worn can be readily renewed.
Having now particularly described and ascertained the nature of my invention
and the manner in which the same is to be performed I declare that I claim as my
invention of "Improvements in tramway or rope rollers or pulleys for collieries,
quarries and for other purposes"
First—Making the bearings of the said rollers or pulleys separate from the
frames or boxes, the said bearings consisting of nearly cylindrical blocks having
cross holes in them in which the ends of the roller spindle engage and work
substantially as hereinbefore described and illustrated in the accompanying
Drawings.
Secondly Making in opposite sides or ends of the roller box or frame nearly
cylindrical seats for receiving the separable bearings, the cylindrical parts of the
Baid bearings fitting loosely in the said cylindrical seats and having a little play
therein for the purpose and substantially as hereinbefore described and illustrated
in the accompanying Drawings..
