I, GEORGE WILLIAM ELLIOTT of N° 12 Clarkehouse Road, Sheffield, Yorkshire,
Mining and Mechanical Engineer do hereby declare the nature of my invention for
IMPROVEMENTS IN BEARINGS FOR AXLES OF TRAMS AND PULLIES USED IN MINES
AND QUARRIES to be as follows:-
This invention relates to improvements in the construction of pedestals or
bearings for trams and pullies used in mines and quarries, in order that the lubri-
cation may be more effectual than as usually applied.
To obtain this result I construct the pedestals so that the bearings are perfectly
protected from dirt and dust, and with a chamber partly surrounding the axle.
This chamber is filled with a mixture of hair & wool, wool, or other fibrous material
saturated with the lubricant, and so filled that it may press against the axle and
keep it lubricated. The construction of the pedestal is varied to suit different
conditions of bearings and one arrangement is also applicable to bearings where
rollers or balls are used to reduce friction.
For outside bearings the pedestal is one solid casting having a chamber in
it, with an opening to allow the end of the axle to pass therin, and part of the
chamber forming the bearing for the axle and the remainder, the receptacle to hold
the lubricating matter.
This form of construction also applies to pedestals for pullies.
Where inside bearings are used the pedestal is made in two parts, the strap or
cap, forming the receptacle to hold the lubricating matter, and having flanges
theron whereby it is secured to the tub. That part which takes the pressure due
to the load is made to fit into the strap part, thereby making one set of bolts
secure the pedestal to the tub, and the two parts of the pedestal together-This
form of pedestal is also applicable to bearings where rollers or balls are used to
reduce the friction.
Inside pedestals may also be made with flanges on that part which takes the
pressure due to the load, and the strap part forming the receptacle to hold the
lubricating matter, secured to it, by bolts fastening the bearing part to the tub, or
by a separate bolt or cotter.

I, GEORGE WILLIAM ELLIOTT of No 12 Clarkehouse Road, Sheffield, Yorkshire,
Mining & Mechanical Engineer do hereby declare the nature of my invention for
IMPROVEMENTS IN BEARINGS FOR AXLES OF TRAMS & PULLIES USED IN MINES
AND QUARRIES 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 the construction of pedestals or
bearings; for axles of trams & pullies, used in mines and quarries in order that the
lubrication may be more effectual than as usually applied.
In order to obtain this result, I construct the pedestals so that the bearings are
perfectly protected from dirt and dust, and with a chamber partly surrounding the
axle. This chamber is filled with a mixture of hair & wool, wool, or other fibrous
. material saturated with lubricant, and so filled that it may press against the axle
and keep it lubricated.
In order the better to show the manner in which this is performed I annex a
sheet of drawings.
Fig. 1 is a side elevation of pedestal for inside bearings.
Fig. 2 is an end elevation, one half being a section through the line Q. R of
Fig. 1.
Fig. 3 is a plan of Fig. 1.
Fig. 4 is a side elevation of pedestal arranged for outside bearings.
Fig. 5 is a sectional end elevation of Fig. 4.
Fig. 6 is plan of Fig. 4.
Fig. 7 is an end elevation of pedestal in one solid casting for outside bearings or
roller bearings.
Fig. 8, is a sectional side elevation of Fig. 7.
Fig. 9, is a plan of Fig. 7.
Fig. 10 is a side elevation of pedestal showing dish or chamber secured to
bearing part by rivets or bolts other that those required to secure the bearing part
to the tub.
Fig. 11 is an end elevation of Fig. 10 one half in section.
In these drawings the same letters of reference refer to similar parts in each
Figure.
A is the bearing part attached to the tub.
B is the dish or chamber part to hold wool saturated with oil.
Care the holes for bolts to secure the pedestal to the tub.
D are oil holes for adding oil when required.
W represents the wool saturated with oil.
S. S. are bolts or rivets, securing dish part to bearing part when not secured by
the same bolts that secure the bearing part to the tub.
Figs. 1. 2. 3 show the pedestal arranged in two parts for inside bearings, so that
the bolts which secure the bearing part to the tub, secure the dish or chamber
part also.

page_text: Figs. 45. 6 show the pedestal arranged in two parts for outside bearings, having
one end closed up and an opening for axle at one end only. This pedestal can be
inade in one solid casting as in Figs. 7. 8. 9. and modified in proportions to suit
tubs, or, with the exception of being made in one solid casting, precisely as shown
in Figs. 4. 5. 6.
Figs. 7. 8. 9 represent a pedestal in one solid casting, arranged for rollers and
pullies. It can also be used for tub bearings with a slight modification.
Figs. 10. 11 show a pedestal arranged for inside bearings, with the dish or
chamber part secured to the bearing part by separate bolts or rivets (S. S.) from
those used to secure the bearing part to the tub.
Where the wheel or pully runs loose on the axle the chamber is cast in the boss
of the wheel or pully.
The dish or chamber part may be made of castings as shown in the drawings, or
of sheet steel or iron pressed or stamped into the shape required.
Having 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
Constructing pedestals or bearings for axles of trams & pullies used in mines and
quarries with dishes or chambers partly surrounding the bearings substantially in
the manner shown and described.
