AN IMPROVEMENT IN LUBRICATED BEARINGS FOR SHAFTS OR AXLES to be as follows:
Year: 1884

page_text: We RICHARD HAMMERSLEY HEENAN and RICHARD HURRELL FROUDE both of
Newton Heath Iron Works, Manchester, in the county of Lancaster, Engineers do
hereby declare the nature of our Invention for "AN IMPROVEMENT IN LUBRICATED
BEARINGS FOR SHAFTS OR AXLES to be as follows:-
"
Our invention relates to a construction of bearing for a shaft or axle in such a
manner as to retain the oil or lubricating material, and to prevent passage of other
matter between the rubbing surfaces. For this purpose, we bore the bearing as a
stuffing box larger in diameter, except for a part at one end, than the shaft or axle,
and we fit within this enlarged bore a bush or sleeve which fits round the shaft or
axle, but is shorter than the depth of the bore. We place in the bottom of the bore
a layer of packing; against this we place the bush, then another layer of packing
and finally a gland which can be pressed inwards by screws, thereby tightening
both layers of packing and so preventing leakage of oil or lubricant out from the
bush in which the shaft or axle runs, and also preventing access of liquid or other
matter to the interior of the bearing.

page_text: We, RICHARD HAMMERSLEY HEENAN and RICHARD HURRELL FROUDE, both of
Newton Heath Iron Works Manchester in the county of Lancaster, Engineers do
hereby declare the nature of our invention for "AN IMPROVEMENT IN LUBRI-
CATED BEARINGS FOR SHAFTS OR AXLES" and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
Our invention relates to a construction of bearing for a shaft or axle in such a
manner as to retain the oil or lubricating material, and to prevent passage of other
matter between the rubbing surfaces.
For this purpose we bore the bearing as a stuffing box larger in diameter, except
for a part at one end, than the shaft or axle and we fit within this enlarged bore a
bush or sleeve which fits round the shaft or axle, but is shorter than the depth of
the bore. We place in the bottom of the box a layer of packing; against this we
place the bush, then another layer of packing, and finally a gland which can be
pressed inwards by screws, thereby tightening both layers of packing and so
preventing leakage of oil or lubricant out of the bush in which the shaft or axle
runs, and also preventing access of liquid or other matter to the interior of the
bearing.
The accompanying drawing is a longitudinal section of a bearing according to
our invention. The shaft A is surrounded by the bush or sleeve B which is fitted
in the box of the bearing C. There is a space for packing, which may be asbestos,
at D, and another packing at E on which bears a gland F, which is secured to the
bearing by bolts or screws in the usual way. There may be an oil hole at G, a
groove H being cut along the interior of the sleeve for distribution of the lubricant.
Having now particularly described and ascertained the nature of our invention
and in what manner the same is to be performed, we declare that what we
claim is :-
The construction of lubricated bearing for a shaft or axle, with an internal bush
or sleeve surrounding the axle, and packed at both ends, substantially as and for
the purposes herein set forth.
