Improvements in Bearings for Horizontal Shafts and Spindles.
I, THOMAS NIELD ROBINSON, of Thomas Robinson and Son Limited, of Railway
Works, Rochdale, in the County of Lancaster, Machine Makers, do hereby declare
the nature of this invention to be as follows:-
My invention relates to improvements in bearings for horizontal shafts and
spindles, particularly for shafts and spindles having conical bearings and running
at high speeds.
In carrying my improvements into effect I make an annular space forming
an oil reservoir or well in the bearing at the large end of the cone, and I supply
I fit loosely
oil through a passage in the bearing to the small end of the cone.
in a groove on the cone in the annular space forming the oil reservoir a ring or
washer the hole in which is sufficiently large to allow it to be slipped over tho
cone and into the groove in which position the upper part of the ring touches a
stationary sheet metal doctor or equivalent device at the top of the oil reservoir
which communicates by a return passage with the oil supply passage.
When the reservoir is filled with oil and the shaft set in motion the oil being
carried along the cone bearing which it lubricates finds its way into the annular
reservoir where the ring slowly rotating by frictional contact with the shaft
carries the oil upward to the doctor which guides it into the return passage
whence it passes back to the reservoir and so maintains the circulation of the oil
and effectually lubricates the bearing.

İmprovements in Bearings for Horizontal Shafts and Spindles.
I, THOMAS NIELD ROBINSON, of Thomas Robinson and Son Limited, of Railway
Works, Rochdale, in the County of Lancaster, Machine Makers, do hereby declare
the nature of this invention and in what manner the same is to be performed,
to be particularly described in and by the following statement: -
My invention relates to improvements in bearings for horizontal shafts and
spindles, particularly for shafts and spindles having conical bearings and running
at high speeds.
In carrying my improvements into effect I make an annular space forming an
oil reservoir or well in the bearing at the large end of the cone, and I supply oil

page_text: through a passage in the hearing to the small end of the cone. I fit loosely in a
groove on the cone in the annular space forming the oil reservoir a ring or washer
the hole in which is sufficiently large to allow it to be slipped over the cone and
into the groove in which position the upper part of the ring touches a stationary
sheet metal doctor or equivalent device at the top of the oil reservoir which
communicates by a return passage with the oil supply passage.
In the accompanying sheet of drawings
Fig. 1 is a sectional elevation of my improved bearings as applied to a hori-
zontal conical ended shaft, Fig. 2 is a transverse vertical section of the bearing
and Fig. 3 a part plan of the same.
In these views. 1 denotes the bracket which supports the two blocks or bushes
2 in which the conical ends of the horizontal shaft 3 are journalled. The bear-
ings being identical I will for convenience of description refer to one only. In
the bush 2 is formed the annular space 4 and the passages 5, 6 and 7, and in
a groove on the shaft near the large end of the cone is fitted loosely the ring S
which is in contact with the stationary blade or doctor 9 secured to the inside of
the bush 2. A cover 10 is pivoted over an aperture through which oil is intro-
duced into the bearing.
When the annular space 4 forming the reservoir is filled with oil and the shaft
3 is set in motion the oil, being carried along the cone bearing which it lubricates,
finds its way into the annular reservoir 4 where the ring 8 slowly rotating by
frictional contact with the shaft 3 carries the oil upward to the doctor 9 which
guides it into the return passages 5, 6, 7, as indicated by the arrows whence it
passes back to the reservoir 4 and so maintains the circulation of the oil and effec-
tually lubricates the bearing.
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—
1. In combination a conical ended shaft. the bearing block or bush 2 provided
with an oil reservoir and circulating passages, the ring 8 resting loosely in a
groove at the large end of the cone, and the doctor 9 or equivalent device all
substantially as and for the purposes herein set forth.
2. The general combination and arrangement of parts embodying my improve-
ments in bearings for horizontal conical ended shafts substantially as herein
shown and described.
