"I WILLIAM HENRY POOLE of Deane Mill, Rumworth, Bolton, in the County
of Lancaster Cotton Spinner, do hereby declare the nature of my Invention for
"ADJUSTABLE PEDESTALS FOR ROTATING SHAFTS," to be as follows:-
My invention relates to the construction of "Binnacle" adjustable pedestals for
carrying and supporting rotating shafts in such a manner as to allow of 'self-
adjustment so as to reduce strain and friction in case of slight errors of level or
allignment and consists in forming self-adjusting pedestals separate from hangers,
brackets, or pillar clips, provided with turned or cast centre pins on 'the underside
or otherwise, which fit into a swivelling arm or centre mounted in suitable fixings.
These fixings are bolted or otherwise in any convenient way to the hangers, brackets,
or pillar clips receiving the same. The joint between the body of the self-adjusting
pedestal and the cap can be made straight or diagonal, in the latter case the joint
is relieved from side thrust and can be reversed any way to suit the direction of
the shaft.
To prevent the swivelling arms or centres tilting in case of side thrust the
bearings or journals are kept in position by suitable caps, bolted or otherwise.
The construction of this pedestal is unique, being s self-adjusting in
possible direction owing to its being on the principle of an universal joint..

I WILLIAM HENRY POOLE of Deane Mill, Rumworth, Bolton in the County of
Lancaster, Cotton Spinner; do hereby declare the nature of my said Invention for
ADJUSTABLE PEDESTALS FOR ROTATING SHAFTS," and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement:―
My invention relates to the construction of adjustable pedestals for carrying and
supporting rotating shafts in such a manner as to allow of self-adjustment so as to
reduce strain and friction in case of slight errors of level or allignment and consists
in forming self-adjusting pedestals separate from hangers, brackets, or pillar clips,
provided with turned or cast centre pins on the underside or otherwise, which fit
into a swivelling arm or centre mounted in suitable fixings. These fixings are
bolted or otherwise in any convenient way to the hangers, brackets, or pillar clips
receiving the same. The joint between the body of the self-adjusting pedestal and
the cap can be made straight or diagonal, in the. latter case the joint is relieved
from side thrust and can be reversed any way to suit the direction of the shaft.
.
To prevent the swivelling arms or centres tilting in case of side thrust the
bearings or journals are kept in position by suitable caps, bolted or otherwise.
The construction of this pedestal is unique, being self-adjusting in every possible.
direction owing to its being on the, principle of an universal joint.
Fig. 1 is a side elevation of my improved adjustable pedestal for carrying and
supporting rotating shafts Fig. 2 is a sectional elevation through line A. B in
Fig. 1—Fig. 3 is a plan of Fig. 1 with the cap or cover Ọ removed and Fig. 4 is a
top plan of base plate C.
The fixing or base plate C is provided with the bolt hole D'and can be secured.
to hangers, brackets, and pillar clips in any convenient manner. This fixing or
base plate is also provided with the circular or segmental grooves E and the pap
or centre Ground the bolt hole D. The underside of the swivelling or centre
block His provided with a recess which fits the pap or centre G, and the
projections. I which slide or swivel in the circular or segmental grooves E in the
base plate C. The openings a, a, on each side of the fixing or base plate O in
Fig: 4 are. for the purpose of admitting the projections I into the circular or
segmental grooves E.
The swivelling arms or centre pins K are cast to the lower side of the body L
of the pedestal, and are mounted in the bearings M on the centre blook H. The
pedestal is provided with the cap O; the joint P between itself and the body L
can be made straight in the centre of the pedestal as in Fig. 1, or diagonal as in
Fig. 2, the latter being for the purpose of relieving the joint from side thrust, and
can be reversed with the centre block H to suit the direction of the shaft.
To prevent the swivelling arms or centre pins K tilting in case of side thrust
they are secured in position by the caps R, which may be bolted as shewn in Fig. 1,,
or by the sliding cap R' secured to the bearings M by the lips B' in the grooves R³
as in Fig. 5.

page_text: Figs. 6 and 7 shew a modification wherein my improved pedestal is converted
into an adjustable hanger to meet the requirements of shafts hung from a floor or
ceiling. The pedestal L with its swivelling arms or centre pins K are held and
supported in the fork fixing S attached to the swivelling or centre block H
mounted in the fixing or base plate C. The pins T are for the purpose of preventing
the pedestal L tilting in the case of side thrust.
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 construction and arrangement of adjustable pedestals, consisting (of the
body L with the swivelling arms or centre pins K disposed horizontally below the
centre of the pedestal or shaft, the swivelling centre block H and the base plate C,
substantially as herein described and illustrated by the drawings.
