Year: 1884

page_text: I, PIERRE SUBIT, of Eden Street, in the County of Middlesex, Moulder, do
hereby declare the nature of said invention for AN IMPROVED METHOD OF
MOUNTING OR ARRANGING. BEARINGS FOR SHAFTS OR AXLES, to be as follows:-
My Invention relates to an improved method of mounting or arranging bearings
for shafts and axles and it has for its object to reduce friction and consequently to
avoid overheating of the said shafts or axles on their being thrown out of the true.
For the purpose of my Invention the bearings instead of being fixed, as at
present, are mounted on pivots in a frame or carriage, in such a manner that they
are capable of a swinging movement so as to cause the bearings to adapt themselves
to any inequality or irregularity and therefore to cause the shaft or axle to be
always in the true.
.
The said bearings are made in one or two portions as désired.
These swinging bearings may be mounted in any position, and may be applied to
any machine, engine or apparatus.

hereby declare the nature of said invention for AN IMPROVED METHOD OF
MOUNTING OR ARRANGING BEARINGS FOR SHAFTS OR AXLES, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the accompanying drawings,
and to the letters and figures marked thereon, that is to say :--
My Invention relates to an improved method of mounting or arranging bearings
for shafts and axles, and it has for its object to keep the axis of the bearings always
in the same line with that of the shaft or axle and consequently to reduce friction
and to prevent overheating of the shaft or axle, as is now occasioned in the ordinary
methods, when the axis of this latter is thrown out of the true with that of the
bearings; this method of mounting ensures a perfect working.
For the purposes of my Invention, the bearings, instead of being fixed, as in the
systems at present in use, are mounted on pivots in a support, frame or carriage, in
such a manner that they are capable of certain movements, as hereinafter described,
so as to cause the bearings to adapt themselves to any inequality or irregularity
existing in the machine or apparatus, and therefore to cause the shaft or axle to be
always in the true, no matter what may be the relative positions of the bearings.
The said bearings may be made in one or two portions, as desired, and may be
mounted in any position and applied to any machine, engine or apparatus.
I proceed with reference to the accompanying drawings to more particularly
describe my Invention.
"Fig. 1, shews, in elevation, one method of mounting two bearings carrying a
revolving shaft. In order that the nature of my said invention, may be readily
understood, I have shewn one of the bearings placed in an oblique position to the
vertical, whilst the other is in a vertical position, its pedestal being in a direction
oblique to that of the revolving shaft Z.
C.
Fig. 2, is a plan of Fig. 1, and
J 380
Fig. 3; is a face or front view of one of these bearings and of its support and
pedestal.
A, is the bearing which is capable of working or oscillating on two pivots á,
carried in a forked support B. These pivots are screw threaded, and act as set
screws. At its lower end this forked support terminates in a stem C, which is
screw threaded, and works freely in a collar d, forming part of the pedestal D. This
stem is furnished with two nuts c and cl, one above and the other below the collar d.
These nuts have for object to regulate the height of the forked support of the
bearing, and consequently the height of the said bearing. These nuts may, however,
be dispensed with and the collar d, may be tapped internally, into which the screw
threaded stem would work.
觜
Thus it will be readily seen that the bearing is capable of four movements, viz :--
1. An oscillating movement on the two pivots a, at the moment of regulating the
position of the shaft Z.
2. A movement causing it to approach more or less the branches of the forked
support, by the action of the set screws a.
3. A movement of rotation around the vertical, and
4. A movement of ascent or of descent owing to the forked support being capable
of siding in the collar d, and of being raised or lowered.

page_text: It will be thus apparent that, two bearings established under these conditions will
readily adapt themselves with great precision to any revolving shaft, no matter
what may be their positions, which, by reason of their setting up, it is necessary to
give to the pedestal of the bearings.
My improved method of mounting can be applied to all kinds of shafts for the
transmission of movement, and to numerous machines, such for instance as wood
moulding machines, milling machines, circular saws, planing machines, lathes, &c.
The dotted lines in fig. 1 shew the bearings arranged for another position of the
revolving shaft or axle.
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 improved method of mounting or arranging bearings for shafts and axles,
substantially as herein described and shewn in the drawings, and for the purposes
set forth.
