PROVISIONAL SPECIFICATION.
Improvements in Swivelling Bearings for Shafting and the like.
I, CHARLES WHITFIELD, of Anglezarke, Kettering, in the County of
Northampton, Engineer, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to provide improved means for mounting swivelling
bearings for shafting and the like so as to enable them to adjust themselves to the
shafting when the latter gets out of line by vertical or lateral displacement, bending
or other cause.
For this purpose mount the bearing in a bracket between two set-screws or
pivots, tapped into or otherwise secured in the bracket, somewhat in the usual way,
so that the bearing can swivel on the ends of the said set-screws or pivots in a
plane perpendicular to the axes of such set-screws or pivots; but instead of
arranging the set-screws or pivots, and their connection with the bearing, in such
manner that the latter is not free to swivel in a plane parallel with the set-screws or
pivots after it is once adjusted and fixed, I so arrange that the bearing is always
free to swivel in two planes at right angles to each other in order that it may
adapt itself automatically to any displacement of the shaft vertically or laterally
within given limits. I make the bearing either in one piece bored out to the
proper size to fit the shaft, or I make it in two or more parts bolted or otherwise
suitably secured together. At one side of the bearing I prepare a hole or recess
adapted to receive the end of the set-screw or pivot secured in one side of the
bracket as aforesaid. The end of this set-screw or pivot is preferably somewhat
convex, and bears against the bottom of the aforesaid hole or recess in the bearing.
On the opposite side of the bearing I provide a groove or recess which stands
parallel to the axes of the bearing, and in this groove or recess I fit a block of
steel or other suitable material free to slide longitudinally therein. In this block
I form a hole or recess to receive the point of the other set-screw or pivot secured
in the opposite side of the bracket.
It will now be understood that when the bearing is placed in the bracket with
the said block in the groove, and the end of one of the set-screws or pivots in the
hole in the block and with the end of the other set-screw or pivot in the hole in
the opposite side of the bearing the latter will not only be free to swivel on the said
set-screws or pivots in a plane at right angles to their axes, but will also be free to
move in a plane parallel to such axes by reason of the longitudinal groove or
recess in one side of the bearing being free to move on the aforesaid block, while
the set-screw or pivot at the opposite side of the bearing allows the latter to rock
on its point as a fulcrum.
In some cases, as where the pressure on the bearing is always in one direction,
the bearing may be made in one piece open at one side, and this open side may be
covered by a light shell or other appliance in the usual way to prevent the access
of dust or dirt to the journal.
Dated this 17th day of December 1895.

page_text: Improvements in Swivelling Bearings for Shafting and the like.
I, CHARLES WHITFIELD, of Anglezarke, Kettering, in the County of
Northampton, Engineer, 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 :-
The object of this invention is to provide improved means for mounting
swivelling bearing for shafting and the like so as to enable them to adjust them-
selves to the shafting when the latter gets out of line by vertical or lateral
displacement, hending, or other cause.
And in order that the said invention may be fully understood I will now
proceed to describe the same with the aid of the accompanying sheet of drawings,
in which
Figure 1 is a longitudinal sectional view of a bearing with my invention applied
thereto,
Figure 2 a transverse sectional view taken on line X-x of Figure: 1, and
Figure 3 a sectional view taken on line Y-Y of Figure 2,
I mount the bearing A in a bracket B, between two set-screws or pivots C, C,
tapped into or otherwise secured in the bracket B, somewhat in the usual way,
so that the bearing A can swivel on the ends of the said set-screws or pivots
in a plane perpendicular to the axes of such set-screws or pivots; but instead
of arranging the set-screws or pivots, C, C, and their connection with the
bearing A in such manner that the latter is not free to swivel in a plane parallel
with the set-screws or pivots after it is once adjusted and fixed, I so arrange that
the bearing is always free to swivel in two planes at right angles to each other,
in order that it may adapt itself automatically to any displacement of the shaft
vertically or laterally within given limits. I make the bearing either in one piece
bored out to the proper size to fit the shaft, or I make it in two or more parts
bolted. or otherwise suitably secured together. At one side of the bearing I
prepare a hole or recess D adapted to receive the end of the set-screw or pivot C
secured in one side of the bracket B as aforesaid. The end of this set-screw or
pivot is preferably somewhat convex, and bears against the correspondingly shaped
bottom of the aforesaid hole or recess in the bearing. On the opposite side of the
bearing I provide a groove or recess D₁ which stands parallel to the axis of the
bearing, and in this groove or recess I fit a block E, of steel or other suitable
material, free to slide longitudinally therein. In this block E I form a hole or
recess D 2. to receive the point of the other set-screw or pivot.C' which is secured
in the opposite side of the bracket B, and is preferably convex at its end like the
set-screw or pivot C.
It will now be understood that when the bearing A is placed. in the bracket. B
with the said block E in the groove D', and the end of the set-screw or pivot.C!
in the hole in the block E, and with the end of the other set-screw or pivot C in the
hole D in the opposite side of the bearing A, the latter will not only be free to
swivel on the said set-screws or pivots C, C¹, in a plane at right angles to their
axis, but will also be free to move in. a plane parallel to such axis, by reason of the
longitudinal groove or recess D¹ being free to move on the aforesaid block E,
while the set-screw or pivot C at the opposite side of the bearing allows the latter
to rock on its point as a fulcrum.
In the above description, and in the drawing, the block E is described and
shown as applied to one only of the set-screws or pivots C C, but it is obvious
that such a block may be applied to each of the said set-screws or pivots if
preferred.
In some cases the recess. D¹ may take the form of a groove open at the ends, the

page_text: sides of the groove forming lateral guides for the sides of the block E to bear
against.
In some cases, as where the pressure in the bearing is always in one direction,
the bearing may be made in one piece open at one side, and this open side may be.
covered by a light shell or other appliance in the usual way to prevent the access
of dust or dirt to the journal.
Having now particularly described and ascertained the nature of the said:
invention, and in what manner the same is to be performed, 1 declare that what
I claim is :-
In a swivelling bearing for shafting and the like, the use in connexion with one
or both of the set-screws or pivots on which the bearing swivels, of a loose block
adapted to receive the end of its corresponding set-screw or pivot, and to take into
a recess, or between guides in or on the bearing, so as to enable the said bearing
to oscillate in a plane parallel with the axis of the set-screws or pivots as well as.
at right angles thereto, substantially as described.
