I RICHARD HITCHCOOк of the Steam Plough Works, Taunton in the County of
Somerset Engineer do hereby declare the nature of this invention to be as follows:-
This invention has for its object an improved bush or bearing applicable to the
axles of land rollers, cultivators and other axles having bushes or bearings much
exposed to grit and dust.
The improved bush or bearing consists of a socket piece at the end of the axle and
a corresponding piece with a plug fitting into the socket.
The axle is preferably tubular and the socket piece is fixed into its projecting end ;
the cavity of the socket extends beyond the end of the plug and serves as an oil
reservoir.
The plug piece is fixed to the frame of the implement and the plug which is slightly
taper projects inwards through an aperture in the frame and enters and fits the
corresponding passage in the socket piece until a face formed around the base of the
plug abuts upon a corresponding face at the extremity of the socket piece. The plug
is perforated from end to end for the admission of oil, and through this passage the
socket is from time to time filled with the lubricant. A screw plug or cover is provided
to close the oil duct.

An Improved Bush or Bearing Applicable to the Axles of Land
Rollers and other Implements.
I, RICHARD HITCHCOCK of the Steam Plough Works, Taunton in the County of
Somerset, Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed to be fully described and ascertained in and by
the following statement :-
This invention has for its object an improved bush or bearing applicable to the
axles of land rollers, cultivators and other axles having bushes or bearings much
exposed to grit and dust.
The improved bush or bearing consists of a socket piece at the end of the axle and
a corresponding piece with a plug fitting into the socket.
The axle is preferably tubular and the socket piece is fixed into its projecting end,
the cavity of the socket extends beyond the end of the plug and serves as an oil
reservoir.
The plug piece is fixed to the frame of the implement and the plug which is
slightly taper projects inwards through an aperture in the frame and enters and fits
the corresponding passage in the socket piece until a face formed around the base
of the plug abuts upon a corresponding face at the extremity of the socket piece.
The plug is perforated from end to end for the admission of oil, and through this
passage the socket is from time to time filled with the lubricant. A screw plug or
cover is provided to close the oil duct.
In the drawings hereunto annexed I have shewn various views of a bearing
constructed as above described for the end of the axle of a land roller.
Figure 1 is a side elevation, Figure 2 a front elevation and Figure 3 a section
through the line A. B. Figure 1. Figures 4 and 5 shew end and side views of the
bush separately, and Figures 6 and 7 shew similar views of the plug.
A is a cast iron bracket by which the bearing is carried. B is the plug projecting
from a plate B-this plate is firmly bolted to the bracket A by bolts B. B' is a
perforation formed through the plug from one end to the other and at the front end
entering a small oil cup formed on the outer side of the plate B¹. B' is a lid for
closing over the top of the oil cup. C is the bush which is to revolve upon the
exterior of the plug B. D is a hollow tubular axle into the end of which the bush C
is secured. The inner end of the bush is preferably closed as shewn. The inner end
of the plug is also closed say by a disc of wood with the exception of a small hole
at the top to be filled in with a few threads of worsted so that the hollow interior of
the plug may form an oil reservoir from which oil may escape slowly through the
worsted wick. The plug thus forms an oil reservoir holding sufficient oil to last for a
considerable length of time.

page_text: By making the bush or bearing in the above way grit and dirt is effectually
excluded from getting between the wearing surfaces of 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. The construction of the bushes or bearings for the axles of land rollers and such
like implements substantially in the manner herein before described.
2. The combination of the bracket A, plug B, bush C and hollow axle D substantially
as described.
