I THOMAS DAVIES of Rhostyllen Foundry Wrexham, Engineer, do hereby declare
the nature of this invention to be as follows:-
The invention relates to axle bearings for rollers or pulleys used for carrying
traction ropes or for other axles in exposed situations away from regular supervision.
The object is to provide bearings which shall allow the axles to run freely keep the
same automatically lubricated, be easily renewed and repaired and require the
minimum of attention to keep them in good working order.
The invention consists essentially of a box to contain oil or lubricant fitted internally
with two movable carriers having axle bearings, in combination with a roller or rollers
carried in the said bearings, and when one roller is used two guide pieces attached to
the carriers above mentioned.
A further improvement consists in making the carriers with taper bearings
extending towards the interior of the box containing oil or lubricant and in
hollowing the roller at the sides so as to provide a taper axle to fit in the said
bearings.
A third improvement consists in providing the box for oil or lubricant containing
the bearings with a cover secured thereto by cottars fitting in lugs cast with the said
cover.
In practice the roller or rollers is or are fitted between the carriers and the pieces
are inserted in the oil box with the said roller or rollers dipping into the oil or
lubricant in the said box. The spindle of the pulley or its equivalent is then placed
between the guides or rollers and rests on the said roller or rollers after which the
cover of the oil box is secured in position.
Dated this 3rd day of Auơnst 1886.

I THOMAS DAVIES Rhostyllen Foundry, Wrexham Engineer do hereby declare the
nature of my invention for IMPROVEMENTS IN AXLE BEARINGS and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
The Invention relates to Axle bearings for rollers or pulleys used for carrying
traction ropes or for other axles in exposed situations away from regular supervision.
The object is to provide bearings which shall allow the axles to run freely, keep the
same automatically lubricated, be easily renewed and repaired, and require the
minimum of attention to keep them in good working order.
The invention consists essentially of a box to contain oil or lubricant fitted 1
internally with two movable carriers having axle bearings, in combination with a
roller or rollers carried in the said bearings and when one roller is used two guide
pieces attached to the carriers above mentioned.
The invention also consists of a frame with the oil box at each end with wrought
Iron Staple (marked L) in each end of the Oil boxes Fig. 16 Sheet 2.
A further improvement consists in making the carriers with taper bearings
extending towards the interior of the box containing oil or lubricant, and in hollowing
the roller at the sides, so as to provide a taper axle to fit in the said bearings.
A third improvement consists in providing the box for oil or lubricant containing
the bearings with a cover, secured thereto by cottars, fitting in lugs cast with the said
cover, see Fig. No. 15 Sheet 2.
A fourth improvement consists of a sliding cover secured by the ends of cover
sliding or fitting in grooves of the oil box, and further secured by a loose rivet or
cottar D dropping into box behind the said carriers see Fig. 3 Sheet 1.
A fifth improvement consists of two bolts let into slots at the bottom of Oil Box at:
each end to secure cover or lid, see Figs. 17, 18, & 19 Sheet 2, and to keep shaft or
spindle in a steady position.
In practice the roller or rollers is or are fitted between the carriers, and the pieces
are inserted in the oil box with the said roller or rollers, dipping into the oil or
lubricant in the said box. The Spindle of the pulley or its equivalent is then placed
between the guides E & F on sheet 1 or rollers, and rests on the said roller or rollers
after which the cover of the oil box is secured in position.
