page_text: LETTERS PATENT to Allan Hodgson, of No. 6, Grove Square, Gomm Street,
Stockport Road, in the City of Manchester, Millwright and Engineer, for
the Invention of "IMPROVEMENTS IN APPARATUS FOR LUBRICATING THE
WORKING PARTS OF MACHINERY, WHEELS, PULLIES, AND LEVERS, SUCH AS
WORK ON SHAFTS, SPINDLES, STUDS, AXLES, OR OTHER COMMON CENTRES
OF MECHANICAL MOVEMENTS."
Sealed the 1st February 1878, and dated the 1st August 1877.
PROVISIONAL SPECIFICATION left by the said Allan Hodgson at the Office
of the Commissioners of Patents on the 1st August 1877.

Road, in the City of Manchester, Millwright and Engineer. "IMPROVEMENTS IN
APPARATUS FOR LUBRICATING THE WORKING PARTS OF MACHINERY, WHEELS,

"
This Invention consists of a bush, which may be made of cast iron or other metal,
and of any shape or dimensions, to adjust to wheels, pullies, or other loose working
parts of machinery.
The part of the bush entering the boss of the wheel or other orifice is to be made
cylindrical, or conical, according to the bore or shape of the hole or orifice.
The part of the bush not entering the orifice is arranged in size and shape to
provide for it being made hollow to contain oil or other lubricating fluid, which are
called oil chambers or reservoirs. From these reservoirs the lubricating fluid is
delivered through channels or tubes directly under the boss of the wheel or pulley,
and between the working surfaces of the wheel or pulley and the bush.

page_text: The peculiar shape of the bush, with its collar, oil chambers, and tubes may be
made with cores during the process of casting, or cut and drilled out of the solid
metal.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Allan Hodgson in the Great Seal Patent Office on the 1st February
1878.
ALLAN HODGSON, of No. 6, Grove Square, Gomm Street, Stockport Road, in the
City of Manchester, Millwright and Engineer. "IMPROVEMENTS IN APPARATUS
FOR LUBRICATING THE WORKING PARTS OF MACHINERY, WHEELS, PULLIES, AND
LEVERS, SUCH AS WORK ON SHAFTS, SPINDLES, STUDS, AXLES, OR OTHER COMMON
CENTRES OF MECHANICAL MOVEMENTS."
This Invention consists of a bush or shell, which may be made of cast iron or
other metal, and of any shape or dimensions to adjust to wheels, pullies, levers,
shafts, or other loose working parts of machinery.
The part of the bush or shell entering the boss of the wheel or pulley or other
orifice, or placed upon a revolving shaft, is to be made cylindrical or conical
according to the shape of the hole or orifice, and also arranged in size and shape to
provide for its being made with one or more hollow chambers or reservoirs to
contain oil or other lubricating fluid, which is delivered through channels or tubes
directly under the boss of the wheel or pulley, and between the working surface of
the wheel or pulley and the bush or shell; or when the bush or shell is placed on a
shaft, the oil or other fluid is delivered from the inner surface of the bush or shell to
the exterior of the shaft.
On the accompanying Sheet of Drawings,―
Fig. 1 is an external view; Fig. 2, a section; and Fig. 3, an end view of one of my
improved bushes adapted for lubricating the interior of the boss of a wheel, pulley,
or other orifice.
a, representing the body of the bush; b, the oil chamber; and c, the delivering
tube, which it will be seen is turned up at its termination to meet the interior of
the boss of the wheel or pulley. To the chamber b is screwed the screw d, which
when removed allows the chamber to be supplied with oil, but when screwed in
the chamber is air-tight, and only allows oil to be drawn out slowly but efficiently
when the wheel is revolving, and the same effect takes place when the bush
or shell is applied to a shaft, the delivering tube being turned towards the exterior
of the shaft.
The Figures represent one of the simplest forms of the improved bush or shell,
but it is evident that I may modify its form and arrangement in any way required
to suit the various parts of machinery to which it can be advantageously applied
and in all cases the shapes of the bushes, with their collars, oil chambers, and tubes
may be made with cores during the process of casting, or cut and drilled out of the
solid metal.
Having now described the nature of my said Invention, I desire to be understood
that I claim the improved mode and apparatus for lubricating the working parts of
machinery, wheels, pullies, and levers, such as work on shafts, spindles, studs, axles,

page_text: or other common centres of mechanical movements, as herein described and
illustrated on the accompanying Sheet of Drawings, or any mere modification
thereof.
In witness whereof, I, the said Allan Hodgson, have hereunto set my hand and
seal, this Thirtieth day of January, in the year of our Lord One thousand
eight hundred and seventy-eight.
