Sam Mason, at the Office of the Commissioners of Patents, with their
Petition, on the 11th September 1867.
We, EDWARD KENWORTHY DUTTON, of Manchester, in the County of Lan-
caster, Consulting Engineer, and SAM MASON, junior, of the same Place,
Machinery Agent, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE BEARINGS OF HYDRO-EXTRACTORS," AND IN THE METHOD
OF SUPPLYING LUBRICATING MATTER TO THE SAME, APPLICABLE ALSO TO THE LUBRI-
CATING OF THE BEARINGS OF OTHER MACHINERY," to be as follows:-
Our improvements in the bearings of hydro-extractors relate to the bearings
in which the journals of the cage shaft run, and consist in forming the said
bearings of three or more blocks or pieces of hard wood suitably formed to be
fitted into recesses formed in appropriate portions of the hydro-extractor or its
framing, the said blocks of wood being arranged at equal distances around
the centre of the shaft, taper keys screwed at one end and fitted with nuts being
employed to force the blocks nearer to the shaft as they wear.
The bearing
formed by the said blocks of wood is preferably bored to fit the "journal" as
is usual. The method of supplying lubricating matter to the said bearings is
also applicable to other "bearings" than those above described, and to the
"bearings" of other machinery than hydro-extractors, more especially to
"upright bearings," and to the "bearings" of shafts running at a "high
speed." In the case of an "upright bearing" an oil case or dripper of a
circular form is fitted below the said bearing in such a manner as to revolve

page_text: with the shaft, and to "catch" the oil as it runs from the bearing, the cir-
cumference of the said "oil case" forming a circular channel in which the
oil collects when the case is revolving. A stationary pipe or tube is fitted or
formed at its lower end with a curved scoop having an open mouth, which is
immersed or partially immersed in the oil, the upper end of the pipe being
suitably formed to deliver the oil to the upper part of the bearing, the motion
imparted to the oil causing it to enter the mouth of the curved pipe, and to
ascend the pipe until it "runs over" at the upper end of the pipe. The mouth
of the pipe is curved in a direction contrary to the direction of motion of the
oil. Two pipes with their "scoop" ends curved in opposite directions may be
employed when the shaft or journal does not always revolve in the same direc-
tion. In the case of horizontal bearings a circular oil dripper is fitted to the
shaft or journal on one or on each side of the bearing, the oil from the said
bearing falling or being conducted into the said dripper. The circumferential
speed of the said dripper must be sufficient to cause the oil to be carried
around when the shaft revolves, a suitably formed pipe conducting the oil
from the dripper, and delivering it to the bearing in a similar manner as
above described in reference to the vertical bearing.
