Improvements in Adjustable Bearings for Carrying Shafts and the like
Revolving Bodies.
I, STEPHEN WILLIAM CHALLEN, of Derwent Foundry, Constitution Hill, in the
City of Birmingham, Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in adjustable bearings which are
primarily intended for line shafting, but which may be used in many cases for
short shafts.
In constructing a bearing according to this my invention, I make a basal
bracket, having means for being secured to a floor, wall or ceiling &c. This
bracket is further made to adjustably receive a pivoted arm axially at right angles
to the base. The forward part of this arm is also similarly formed (as the base)
to adjustably receive a stem or post which latter is directly connected with the
bearing proper, either by being formed in one therewith, or otherwise secured
thereto. Now this my invention refers more particularly to the adjustment of
either or both of the pivoted arm and the bearing post, as follows:-
Speaking of the arm for instance, I form upon its stem a bearing neck for a
suitable length, and from such bearing to the end, its diameter is reduced, and
upon such reduced part is formed a square screwthread to receive a screw nut.
The base is made to accommodate this by having at its outer part a bearing to
suit the aforesaid neck, and an extended bearing which agrees with the outside
diameter of the screw thread. Between this latter bearing and the neck bearing,
a space is left, in which lies the screw nut acting as a collar upon each side
against each bearing. Suitable provision such as tommy bar holes, notches or
the like is made upon such nut whereby it may be turned around for adjustment.
Similar means are carried out upon the bearing post, and upon the forward part
of the pivoted arm.
By these means I obtain a long steady bearing, with a strong junctional neck,
and a ready and simple but effective adjustment, without interference with angular
self adjustment. If desired binding screw pins may be further used to rigidly
secure the various parts in a given position.

ascertained in and by the following statement:―
This invention relates to improvements in adjustable bearings which are
primarily intended for line shafting, but which may be used in many cases for
short shafts.
In constructing a bearing according to this my invention, I make a basal
bracket, having means for being secured to a floor, wall or ceiling &c. This
bracket is further made to adjustably receive a pivoted arm axially at right angles
to the base. The forward part of this arm is also similarly formed (to the base)
to adjustably receive a stem or post which latter, is directly connected with the
bearing proper, either by being formed in one therewith, or otherwise secured
thereto. Now this my invention is more particularly in connection with the
adjustment of either or both of the pivoted arm and the bearing post, as follows:
In order to more clearly explain this my invention, I have appended hereunto
an illustrative drawing upon which are figures and numbers of reference, similar
numbers referring throughout the several views to the same thing or part, and
in which:
-:
Fig. 1, is a general part sectional side view of a bearing made according to
this my invention.
Fig. 2, is a detached view of the adjustable arm, and Fig. 3, is a detached
view of the adjustable bearing stem.
Similar reference numbers are used throughout the several views to mark the
same thing or part.
5, is the bracket or base which may be secured to floor, wall, ceiling, or other
fixture. In this base socket like holes 6 and 7, are made to receive the rear
parts 8 and 9 of the arm 10. Also in the arm 10, socket like holes 11 and 12,
are made to receive the parts 13 and 14 of the bearing stem 15. It will be seen
that the parts 9 and 14, are respectively made much smaller in diameter than
their adjacent parts 8 and 13, and for the following reasons: The maximum
breaking strain is of course in the case of the arm 10, at or about the point 16,
that is, where it is supported in the boss 17 of the bracket 5, and therefore the
maximum strength (size) is given to such part, while the tail part 9, may be
safely reduced in diameter considerably. This reduction in the size of the tail
piece permits of a correspondingly smaller screw nut 18, than has hitherto been
used, which is necessarily more readily adjusted; and also affords economy in
weight and material both of which are very desirable, in addition to increased
compactness.
The same remarks apply to the parts 13 and 14, of the bearing stem 15.
Binding screw pins 19, may if desired be further used to rigidly secure the
parts in a given position.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is: --
1. The improvements in adjustable bearings for carrying shafts and the like
revolving bodies as herein set forth, that is to say, providing the arm 10, and
bearing stem 15, severally or collectively with comparative large shoulder
parts 8 and 13, with reduced adjusting extensions 9 and 14, as shown upon the
drawings.
Dated this 26th day of January 1900.
