PROVISIONAL SPECIFICATION.
Improved Pedestal for Carding Engines.
I JOHN FREDERICK BRADBURY of Parel, Bombay, India, Mill Manager, do
hereby declare the nature of this invention to be as follows:-
My said invention relates to an improved pedestal or bearing for carrying the
driving shaft of cylinders in carding engines so constructed as to permit of
accurately adjusting or setting the said driving shaft in relation to other parts of
the carding engine.
According to my said invention the shaft is borne in a wedge shaped block
against the inclined sides of which bear the inner faces of two vertical wedges
provided with setting screws and means for rotating them preferably worms and
worm wheels.
The outer faces of the vertical wedges bear against suitably shaped facings in the
interior of the pedestal.
In order to raise or lower the shaft without producing any horizontal displacement
thereof both side wedges are raised or lowered an equal distance in the same
direction.
In order to adjust the position of the shaft horizontally one of the side wedges is
raised and the other lowered through equal distances.
By varying the relative positions of the two wedges with regard to each other
and to the central wedge shaped block carrying the shaft the position of the latter
may be adjusted vertically and horizontally.
Å screw may be provided in the pedestal cap for pressing down the central
bearing block on to the adjusting wedges.
Graduated discs and pointers are provided for indicating and controlling the
degree of adjustment.
Dated 3rd day of February 1892.

COMPLETE SPECIFICATION.
Improved Pedestal for Carding Engines.
1 JOHN FREDERICK BRADBURY of Parel, Bombay, India, Mill Manager, 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:-
My said invention relates to an improved pedestal or bearing for carrying the
driving shaft of cylinders in carding engines so constructed as to permit of
accurately adjusting or setting the said driving shaft in relation to other parts of
the carding engine.
According to my said invention the shaft is borne in a wedge shaped block
against the inclined sides of which bear the inner faces of two vertical wedges
provided with setting screws and means for rotating them preferably worms and
worm wheels.
The outer faces of the vertical wedges bear against suitably shaped facings in the
interior of the pedestal.
In order to raise or lower the shaft without producing any horizontal displacement
thereof both side wedges are raised or lowered an equal distance in the same
direction

page_text: In order to adjust the position of the shaft horizontally one of the side wedges is
raised and the other lowered through equal distances.
By varying the relative positions of the two wedges with regard to each other
and to the central wedge shaped block carrying the shaft the position of the latter
may be adjusted vertically and horizontally.
A screw may be provided in the pedestal cap for pressing down the central
bearing block on to the adjusting wedges.
Graduated discs and pointers are provided for indicating and controlling the
degree of adjustment.
The accompanying drawing shows a pedestal constructed in accordance with my
said invention.
Fig. 1 is a front elevation partly in section.
Fig. 2 is an end clevation.
Fig. 3 is a plan with the cap or cover removed.
In all the figures the same letters refer to the same parts.
A is the body of the pedestal containing the adjustable parts.
B is the cap or cover.
The shaft is carried by the wedge shaped block a the inclined surfaces of which
are supported by the vertical wedges bb. Setting screws c c take into corresponding
threaded holes or nuts in the wedges bb. Secured to the setting screws c c are
worm wheels indicated by dotted lines at c¹ cl.
For rotating the worm wheels of the setting screws independently of each other I
provide the worms d d mounted on separate setting shafts e e having squares at their
ends for receiving a screw key.
By rotating either or both of the setting shafts ee in the same or in contrary
directions the position of the shaft may be adjusted in the manner hereinbefore set
forth.
Graduated discs 9 g are mounted on the setting shafts and indexes h h are
provided in combination therewith for readily ascertaining and controlling the
displacement of the shaft.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is-
1. The combination in a pedestal or bearing of a wedge shaped shaft-carrying
block with vertical wedges provided with means for independent adjustment, sub-
stantially as herein before described and shown.
2. The combination of the wedge shaped bearing block a the side wedges bb the
setting screws ee the worm wheels c¹¹ the worms d d and the independent setting
shafts ee the whole mounted in a suitable casing and forming a support for a
carding engine shaft substantially as hereinbefore described and shown.
