I, WILLIAM WOOLER of Yele Street, Oldham, in the County of Lancaster,
Millwright, do hereby declare the nature of my invention for "IMPROVEMENTS IN
PEDESTALS OR BEARINGS FOR HORIZONTAL SHAFTS to be as follows:-
"
This invention relates principally to the construction of the bearings of pedestals
employed for supporting the horizontal shafting used in mills or manufactories for
driving machinery and is also applicable to the shafts of steam engines or machines in
general when carried in a horizontal position.
The objects of this invention are to dispense with the use of the brass steps ordinarily
employed and to keep the bearing and journal of the shaft thoroughly lubricated.
The improved pedestal or bearing is entirely of cast iron and consists of two parts
only, the base or chief portion is made with a long cylindrical bearing, at each end of
which is an oil recess somewhat deeper than the bearing. The outside wall on each
side of the oil recesses is carried higher than the bearing and is bored out just free of
the shaft.
On the shaft (which is of wrought iron or steel) I fix a long collar of cast iron,
which works in and is supported by the cast iron bearing forming part of the pedestal.
This collar always runs in the oil and thus the bearing of the shaft is kept thoroughly
lubricated.
The cap is also of cast iron and fits into the upper half of the long collar, being held
down by bolts and nuts as usual.
When it is desired that the pedestal shall at the same time act as a collar to prevent
endwise movement of the shaft, I make the long cast iron collar with a central flange,
which works in a corresponding groove or recess made in the cast iron bearing and in
the cap for that purpose and thus the necessity for collars outside the pedestal is
dispensed with.

Improvements in Pedestals or Bearings for Horizontal Shafts.
I WILLIAM WOOLER of Yele Street Oldham in the County of Lancaster, Millwright
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:-
This invention relates principally to the construction of the bearings or pedestals
employed for supporting the horizontal shafting used in mills or manufactories for
driving machinery and is also applicable to the shafts of steam engines or machines in
general when carried in a horizontal position.
The objects of this invention are to dispense with the use of the brass steps ordinarily
enployed and to keep the bearing and journal of the shaft thoroughly lubricated.
Such being the nature and object of my said invention, the manner in which the
same is to be performed or carried into practical effect will be readily understood on
reference to the annexed sheet of drawings and the following explanation thereof.
Fig. 1 in the annexed drawings is a vertical section taken longitudinally through
the centre of a pedestal or bearing constructed according to my invention. Fig. 2. is a
similar section taken transversely through about the line A-B (Fig. 1) and Fig. 3 is
a plan view, with the cap removed of a modification thereof applicable to such shafts
as have to resist an endwise thrust.
The improved pedestal or bearing is entirely of cast iron and consists of two parts
only. The base or chief portion a. a. (Figs. 1. and 2) is made with a long cylindrical
bearing b. b. at each end of which is an oil recess e. c. somewhat deeper than the
bearing.
These two recesses may be connected together by a passage 61.61. The outside wall
on each side of the oil recesses c. c. is carried higher than the bearing and is bored out
just free of the shaft d. d.
On the shaft d d (which is of wrought iron or steel) I fix a long collar or boss e. e.
of cast iron which works in and is supported by the cast iron bearing bb forming part
of the pedestal. This collar or boss e. e. always runs in the oil and thus the bearing
of the shaft d. d. is kept thoroughly lubricated.
The cap ff. is also of cast iron and fits onto the upper half of the long collar e. e,
being held down by bolts and nuts as usual.
When it is desired that the pedestal shall at the same time act as a collar d. d, to
prevent end wise movement of the shaft, I make the long cast iron collar or boss ee
with a central flange g. g. (as shown at Fig. 3) which works in a corresponding groove
or recess made in the cast iron bearing b. b. and in the cap f. f. for that purpose and
thus the necessity for collars outside the pedestal is dispensed with.

page_text: 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 :-
The improvements in pedestals or bearings for horizontal shafts substantially as
hereinbefore described and illustrated by the drawings annexed consisting of the
combination in a pedestal of a long cylindrical bearing, at each end of which is an oil
recess somewhat deeper than the same, with a corresponding long collar or boss fixed
to or formed with the shaft; and either with or without a central flange to resis
endwise thrust.
