PROVISIONAL SPECIFICATION.
An Improved Bearing for Lubricating Shafts, Spindles, and the like.
I, JOHN FLEMING GIBB, of 27, Town Hall Street, Sowerby Bridge, in the County
of York, Overlooker, do hereby declare the nature of this invention to be as
follows;-
My invention consists in a new means and method of lubricating shafting,
spindles, and studs of most descriptions; to do which I form on, or attach to such
shafts or spindles an oval or double cone boss, fitting into almost corresponding
shaped concave bearings for the oval shaped boss to revolve in, the primary object
of my improvements being to continuously and freely lubricate the said oval
bearing. In putting my invention into practice I make the oval so that only the
middle portion thereof bears upon the brasses, and the parts are se arranged that
there is no contact at the apex of the cone with the brasses, but a slight space is
left between, the object being to ensure the lubricant to gravitate from each apex
of the oval towards the middle thereof, and to that part where the bearing is the
most severe, consequently the parts where the weight of the shaft bears mostly,
is freely and continuously lubricated, and whenever the shafting or spindle is
stopped for short or long periods the lubricant will meanwhile gravitate towards
the bottom of the cone bearing, thus the friction is lessened and the power to
drive the shafts or spindles is very much lessened.

An Improved Bearing for Lubricating Shafts, Spindles, and the like.
I, JOHN FLEMING GIBB, of 27, Town Hall Street, Sowerby Bridge, in the County
of York, Overlooker, 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; ―

spindles, and studs of most descriptions; to do which I form on, or attach to such
shafts or spindles an oval or double cone boss fitting into almost corresponding
shaped concave bearings for the oval shaped boss to revolve in, the primary object
of my improvements being to continuously and freely lubricate the said oval
bearing. In putting my invention into practice I make the oval so that only the

there is no contact at the apex of the cone with the brasses but a slight space is
left between the object being to ensure the lubricant to gravitate from each apex
of the oval towards the middle thereof, and to that part where the bearing is the
most severe consequently the parts where the weight of the shaft bears mostly,
is freely and continuously lubricated, and whenever the shafting of spindle is
stopped for short or long periods the lubricant. will meanwhile gravitate towards
the bottom of the cone bearing, thus the friction is lessened and the power to
drive the shafts or spindles is very much lessened.
In order to illustrate my invention I have annexed the accompanying sheet of
drawings, illustrative, thereof wherein :-
Fig. is sectional elevation, taken on line 1, 1, of Fig. 2 which is side elevation
of one method of applying our invention, and Fig. 3 is similar sectional eleva-
tion taken on line 2, 2, of Fig. 4, shewing another method of application.
Referring firstly to Figs. I and 2, which shew my improvements applied to a
bearing in which the pressure is on the upper surface of the shaft or spindle,
letter represents the shaft or spindle to be lubricated. This shaft or spindle
at the point to be lubricated is made oval elliptical or double conical as shewn
ata. The brass or other antifriction metal is represented at and it is arranged
to come into contact with the shaft only at the central part or largest diameter all
of the elliptical or double conical bearings a¹.
Figs. and shew the application of my improvements to a bearing where the
contact is on the underside of the shaft.
When the shaft or spindle is at rest, the oil or other lubricant gravitates towards
the part where the pressure comes, and lubricant is principally required, and
when said shaft commences to rotate the oil still tends to gravitate towards part a
instead of being thrown out at the ends of the bearing as hitherto. In practice
it is found that the oil gravitates sufficiently to form a slight cushion of lubricant
between the shaft or spindle, and the antifriction metal, and further it is found
that the shaft does not require lubricating as frequently as when ordinary forms
of bearings are employed.
The bearing is applicable to shafts or spindles of any description, whether said
shafts or spindles are entirely surrounded by antifriction metal or not.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
-
In bearings for shafts, spindles and the like, the formation of an elliptical or
double conical bearing surface, substantially as shewn in the drawings and for
purposes described.
