Improvements in the Construction of Adjustable Pedestals for
Rotating Shafts.
We, WILLIAM HARGREAVES of the firm of Hick, Hargreaves and Co., Soho Iron
Works, and ROBERT HARWOOD, Manager, both of Bolton in the County of Lancaster,
do hereby declare the nature of our said invention to be as follows:-
Our invention relates to the construction of adjustable pedestals employed for
rotating shafts and has for its object that of allowing self-adjustment to reduce strain
and friction in case of slight errors of level or allignment.
The underside of the body of the pedestal or bearing is provided with a vertical
stem, the lower end of which is convexed or globular to a radius from the centre of
the pedestal or bearing. The base plate of the pedestal is constructed on its upper side
with a concaved or globular surface to receive the end of the aforesaid vertical stom
the underside of the same being convexed or globular to receive a plate or disc
secured to the underside of the vertical stem by a stud or its equivalent, which forms
the medium for securing the pedestal to the base plate.
;
The base plato is provided with an oblong hole or slot to admit a pap on the under-
side of the vertical stem, which allows of the pedestal swivelling longitudinally but
prevents it tilting laterally.
The cap is constructed in any convenient way and secured to the body of pedestal by
bolts or their equivalents.
This improved pedestal can be constructed in any convenient manner and be supported
on hangers, brackets, or pillar clips.

Works, and ROBERT HARWOOD, Manager, both of Bolton in the County of Lancaster,
do hereby declare the nature of our said invention 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 the construction of adjustable pedestals employed for
rotating shafts and has for its object that of allowing self-adjustinent to reduce strain
and friction in case of slight errors of level or allignment.
The underside of the body of the pedestal or bearing is provided with a vertical
stem, the lower end of which is convexed or globular to a radius from the centre of the
pedestal or bearing. The base plate of the pedestal is constructed on its upper side
with a concaved or globular surface to receive the end of the aforesaid vertical stem;
the underside of the same being convexed or globular to receive a plate or disc secured
to the underside of the vertical stem by a stud or its equivalent, which forms the
medium for securing the pedestal to the base plate. The base plate is provided with
an oblong hole or slot to admit a pap on the underside of the vertical stem, which
allows of the pedestal swivelling longitudinally but prevents it tilting laterally.
The cap is constructed in any convenient way and secured to the body of pedestal
by bolts or their equivalents.
This improved pedestal can be constructed in any convenient manner and be supported
on hangers, brackets, or pillar clips.
In order that our Invention may be fully understood and readily carried into
operation we will now proceed to describe the drawings hereunto annexed; the samo
letters of reference being used throughout all the figures to indicate the same or
corresponding parts.
Fig. 1 is a sectional elevation of our improved adjustable pedestal for rotating
shafts through line A. B in Fig. 3-Fig. 2 is a longitudinal sectional elevation through
line C. D in Fig. 3; the latter being a plan of same.
E is the body of the pedestal or bearing for the shaft provided with the vertical
stem G, the underside of which is made in a convex or globular form to a radius from
the centre of the pedestal or bearing. The upper side of the base plate H is constructed
with the concaved or globular surface W to receive the convexed or globular end G'
of the stem G. The underside of the base plato H is provided with the convexed or
globular surface I struck with a radius from the centre of the pedestal or bearing on
which bears the concaved plate or disc K, the latter being secured to the underside of
the vertical stem G by the stud or set screw L, and by which the adjustable part of
the pedestal or bearing is secured to the base plate H. The base plate H is provided

page_text: with the oblong hole or slot M to admit the pap N on the underside of the vertical
stem G, which allows the adjustable part of the pedestal to swivel longitudinally but
prevents it tilting laterally.
The snugs O are cast on the body E of the pedestal or bearing to receive the bolts P,
by which the cap R is secured thereto; the latter having the snugs S to correspond
therewith. The base plate H can be provided with the oil dish T or otherwise as
desired.
Fig. 4 is a sectional elevation of another modification of our improved adjustable
pedestal through line A B in Fig. 6-Fig. 5 is a longitudinal sectional elevation
through line C. D in Fig. 6, the latter being a plan of same.
In this modification the main parts aro similar to those described above, the only
differenco being that the adjustable pedestal or bearing for carrying the shaft is pro-
vided with the steps V, which can be easily replaced in case of wear thereby prolonging
the life of the pedestal.
Fig. 7 is a sectional elevation of our invention when employed for carrying the outor
ends of crank shafts and other similar purposes.
In this modification the convexed or globular surface G¹ on the body E of the
pedestal is increased in diameter to produce the necessary stability for large rotating
shafts, the same being struck with a radius from the centre of the pedestal as before
described. The base plate H is provided with a hole or slot to admit the pap N. In
this arrangement the concaved plate or dise K and the convexed or globular surface I
are dispensed with, the body of the pedestal being held in position on the base plato H
by the weight of the crank or other shaft and its attachments.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is :-
1. In adjustable pedestals for rotating shafts the combination of parts consisting
of the stem G, pap N, holo or slot M, the convexed or globular surfaces GI and I and
the concaved or globular surface W struck with a radius from the centre of the pedestal,
the concaved or globular plate or disc K and the stud L, constructed and operating
substantially in the manner described and as shown on the drawings in Figs. 1 to
inclusive.
2. The construction of adjustable pedestal for rotating shafts substantially as herein
described and illustrated on the drawings in Fig. 7.
