Improvements in Adjustable Bearings for Shafting.
Year: 1887

page_text: Improvements in Adjustable Bearings for Shafting.
I JOSEPH ROBERT LUCAS of 239 St. Vincent Street, Ladywood, Birmingham in
the county of Warwick, Pattern Maker, do hereby declare the nature of this invention
to be as follows:-
Its chief object is to save time in fixing for which purpose the bearings are made
adjustable for the purpose of correcting any irregularity which may occur in fixing
the main brackets.
The bearing is placed in a suitable position on the bracket, and is of the ordinary
ball and cup pattern, improved in such a manner as to allow the cup and bearing to
be adjusted to suit the required centre of the shaft. The cup works in a slot in the
bracket and is adjusted by means of two set pins one on each side or end of the slot,
the back of the bracket is segmental for the purpose of receiving a segmental adjust-
able washer or plate through which a screw pin passes to the ball of the bearing the
said pin being fitted with an ordinary nut.
Thus it will be perceived that the main bracket is first fixed in its required position
after which the shaft is placed in the bearing and the cup adjusted by the set pins
(the bearing moving with it) to bring the shaft to the required centre the ball screw
pin and segmental washer at the back, moving automatically at the same time to suit
the angle of the shafting, when the nut on the screw pin is adjusted which secures the
bearing firmly in position.

I JOSEPH ROBERT LUCAS of 239 St. Vincent Street Ladywood, Birmingham in
the County of Warwick Pattern maker 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, and illustrated by the accompanying
drawings
The chief object is to save time in fixing, for which purpose the bearings are made
adjustable for correcting any irregularity which may occur in fixing the main
bracket.
Fig. 1 shews a side elevation of the bracket or body.
Fig. 2 shews a section of the bracket through the slot.
Fig. 3 shews a side elevation and fig. 4 an end elevation of the adjustable cup
or seat.
Fig. 5 is a side elevation of the bearing with the screw pin and ball complete.
Fig. 6 is a side elevation and fig. 7 a front elevation of the segmental adjustable
washer. Fig. 8 shews the nut and fig. 9 the lock nut.
Fig. 10 shews a side elevation and fig. 11 a front elevation of the bracket or body
with the bearing fixed complete.
The same reference letters apply to all of the drawings.
The bearing A is placed in a suitable position on the bracket B and is an ordinary
bearing with a ball and cup joint commonly called a ball and cup bearing improved
in such a manner as to allow the cup and bearing to be adjusted to suit the required
centre of the shaft which is done as follows:-
The cup C works in a slot D in the bracket and is adjusted by means of two set
pins E one on each side or end of the slot. The back of the bracket at G is segmental
for the purpose of receiving a segmental adjustable washer or plate H through which
a screw pin passes from the ball of the bearing J the said pin being fitted with an
ordinary nut K to which may be added a lock nut I..
Thus it will be perceived that the main bracket is first fixed in its required position
after which the shaft is placed on the bearing and the cup adjusted by the set pins
(the bearing moving with it) to bring the shaft into the required centre the cup and
ball screw pin and segmental washer at the back moving automatically at the same
time to suit the angle of the shafting, when the nut on the screwpin is adjusted which
secures the bearing firmly in position.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1. A bracket or body having a slotted hole with a cup or seat working in the same
as baraibafora Lill

page_text: 2. A bracket or body having a slotted hole with a cup or seat working in the same,
the said cup or seat being adjusted and tightened by set pins as hereinbefore described
and illustrated by the accompanying drawing.
3. A bracket or body having a segmental back and washer, in combination with a
screw pin and nuts for tightening the bearing at the desired angle as hereinbefore
set forth.
4. An adjustable bearing for shafting consisting of the parts arranged and combined
as hereinbefore described and illustrated by the accompanying drawings.
