IMPROVEMENTS IN BEARINGS FOR SILAFTS
Year: 1878

page_text: LETTERS PATENT to Antoine Courne, of No. 50, Rue St. Etienne, Nice, in the
Republic of France, for the Invention of "IMPROVEMENTS IN BEARINGS FOR
SILAFTS."
Sealed the 18th October 1878, and dated the 18th June 1878.
PROVISIONAL SPECIFICATION left by the said Antoine Courne at the Office
of the Commissioners of Patents on the 18th Juno 1878.
ANTOINE COURNE, of No. 56, Rue St. Etienne, Nice, in the Republic of France.
"IMPROVEMENTS IN BEARINGS FOR SHAFTS."
This Invention has for its object improvements in bearings for shafts. For this
purpose I forn a bearing of a hollow box or basin, which is kept partly filled with
oil or oil floating on water. Across the interior of the box or case are two parallel
rollers, each supported and capable of turning on two points, which enter conical
holes at the centre of their ends. The level of the oil in the box is kept somewhat
above the centre of the rollers. The points are formed at the ends of screws, which
screw through holes in the sides of the box. The shaft to be supported also passes
through openings in the sides of the box, and rests between and upon the two
rollers. The top of the bearing is formed by a cover which passes over the top of
the shaft and closes in the top of the box or case.
By supporting a shaft upon rollers running in oil in the manner above described
there will be much less loss of power from friction than with bearings constructed
in the ordinary manner, and great saving in power will be effected.
From the bottom of the box there may be a passage closed by a plug or tap, by
which any dirty oil or sediment can be drawn off.
At the bottom of the box there may also be projecting lugs, by which it can be
bolted down in any position required.

"IMPROVEMENTS IN BEARINGS FOR SHAFTS."
This Invention has for its object improvements in bearings for shafts. For this
purpose I form a bearing of a hollow box or basin, which is kept partly filled with
oil floating on water. Across the interior of the box or case are two parallel rollers,
each supported and capable of turning on two points, which enter conical holes at
the centre of their ends. The level of the oil in the box is kept somewhat above
the centre of the rollers. The points are formed at the ends of screws, which screw
through holes in the sides of the box. The shaft to be supported also passes through
openings in the sides of the box, and rests between and upon the two rollers. The
top of the bearing is formed by a cover, which passes over the top of the shaft and
closes in the top of the box or case.
By supporting a shaft upon rollers running in oil in the manner above described
there will be much less loss of power from friction than with bearings constructed
in the ordinary manner, and great saving in power will be effected.
From the bottom of the box there may be a passage closed by a plug or tap, by
which any dirty oil or sediment can be drawn off.
At the bottom of the box there may also be projecting lugs, by which it can be
bolted down in any position required.
The Drawing hereunto annexed shows a roller bearing for shafts constructed in
the manner above described.
Figure 1 is a vertical section of the bearing, and Figure 2 a plan view of the same,
with its cap or cover removed.
The bearing is composed of a casting A, which can be secured in place by bolts
and nuts, as shown at B, B. The body of the casting forms a hollow box or basin,
which is to be kept partly filled with oil floating on water. C, C, are two parallel
steel rollers passing across the interior of the box; D, D, are the conical points upon
which the rollers turn, or the rollers might turn on other formed axes or trunnions ;
E is the shaft to be supported; it rests upon the rollers C. Each of the two oppo-
site sides of the box is notched out with a semicircular notch, so that the shaft shall
not rest or bear against the sides of the box, but shall rest freely upon the rollers C, C.
His a cap by which the upper part of the bearing and the shaft are covered over
to exclude dirt. The level of the oil in the box is kept somewhat above the points
or axes, upon which the rollers D turn, so that these points or axes are kept well
lubricated with the oil.
At I there is an opening, which can be closed by a screw plug or otherwise; the
opening is for the purpose of drawing off sediment whenever required.
As the shaft F revolves, it turns the rollers C, and as these rollers turn in oil and
water all the revolving parts are lubricated, and the oil which has served for lubri-
cation is carried down to the bottom of the basin, and after being washed in the
water rises again to the surface cleaned and again fit for lubricating.
Having thus described the nature of my Invention and the manner of performing
the same, I would have it understood that I claim the construction of bearings for
shafts, substantially as herein-before described, with a box or casing containing oil,
or oil floating on water, and with two parallel rollers placed across the box for the
shaft to rest and turn upon, the rollers themselves turning upon conical points, which

page_text: enter corresponding recesses in their ends, or turning on other formed axes or
trunnions immersed in the oil.
In witness whereof, I, the said Antoine Courne, have hereunto set my hand and
seal, this 12th day of Decembre 12, in the year of our Lord One thousand
eight hundred and seventy-eight.
