I, WILLIAM EDWIN HEYS, of 70, Market Street, Manchester, in the County of
Lancaster, Fel. Inst. Patent Agents do hereby declare the nature of this invention to
be as follows:-
This Invention relates to a new or improved system of lubrication and these
improvements consist in the employment of granulated metal, shot or other like
material as a conductor for the oil, as a regulator of the delivery and at the same time
as a recuperator.
This granulated metal or shot immersed in the oil provided for lubricating forms
the lubricating mass, permitting the oil to be delivered at or around the shaft to be
lubricated with certainty, and in almost imperceptible quantities; it replenishes the
lubricating chamber or recess economically from the supply in the lubricators which
may be appropriated thereto, irrespective of their forms and dimensions.

page_text: Improvements in and in Connection with Lubricators.
I, WILLIAM EDWIN HEYS of 70, Market Street, Manchester in the County of
Lancaster, Consulting 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:-
These Improvements relate to a new or improved system of lubrication and consist
in the employment of granulated metal, shot, or other like material as a conductor,
for the oil, as a regulator of the delivery, and at the same time as a recuperator.
The granulated metal or like material is immersed in the lubricant, and forms a
mass which permits a constant and almost imperceptible flow of the lubricant to the
shaft to be lubricated and replenishes the lubricating cavity or recess from the supply
economically and irrespective of form or dimensions.
In order to free the lubricant as far as possible from all impurities, there may be
employed one or more suitable filters contained in one or more suitable tubes or
conduits formed or arranged in the bearing or conveniently situated with regard
thereto and through which the lubricant may flow or be forced to the shaft.
There may also be arranged and combined with the lubricating devices an automatic
exhauster for the dirty oil which is produced in spite of all precautions and which
is sometimes productive of accidents from seizing of the shaft.
In order to enable this Invention to be better understood there are appended hereto
three sheets of drawings to which reference is hereinafter made and which illustrate
in what manner these Improvements may be applied to an ordinary bearing. It
will be evident that these Improvements may be similarly applied to other bearings.
Fig. 1 represents a vertical section, partly in elevation, of a Plummer Block
constructed according to these Improvements.
Fig. 2 is a section of a tube or conduit containing a filtering medium.
Fig. 3 and 4 are respectively a plan and a vertical section of a bearing showing
the dirty oil exhauster."
Fig. 5 is a plan of a plate, blade or scraper employed for removing the dirty oil.
Fig. 6 is a view from below, of a pedestal cap showing the dirty oil scraper in
position.
Fig. 7 is an elevation of Fig. 6.
Fig. 8 is a vertical section of a Plummer Block showing the arrangements for
exhausting the dirty oil.
In Fig. 1 two screwed tubes or conduits A. A forming hollow bolts are screwed
into the Plummer Block B and pass through the cap similarly to the bolts ordinarily
used, and receive the nuts by means of which the cap is held down. The small tube C
communicates with the interior of the Plummer Block which is hollow and filled with
the granulated metal or like material. When a filter is not used, the granulated
material is filled into the tube C to the point shown in Fig. 1, the unoccupied space
above being filled with oil about every fifteenth day. The space can obviously be left free

page_text: to any desired extent so as to receive any desired amount of oil. The oil permeates the
granulated material and, because of the capilliary spaces in the granular mass and
their consequent action, an almost imperceptible supply of the lubricant is conveyed
to the bearing without cessation. The result is an effective lubrication and a minimum
oil consumption.
When a filter is desired to be used, such for example as that shown in Fig. 2, it
is supplied with a filtering medium which will allow the oil to pass through it freely.
In the case of the tube shown in Fig. 2 it is supplied with a lid F for the purpose of
preventing the entrance of dust. The filtering material which it is preferred to use
may belong to any of the three following types
(1) Vegetable, animal, or mineral fibres or metallic wire; (2) Thin metallic plates
arranged in a spiral or other form so as to form a filter; (3) Tubular clusters or
bodies having capilliary properties suitable for filtering.
The arrangements for disposing of the dirty oil are illustrated in Figs. 3 4 5 6 7
and 8. A groove in the form of a V or other suitable form, as will be hereinafter
explained, is formed in the interior surface of the cap or cover of the bearing.
This
groove terminates in the holes S or in suitable channels or recesses for the reception
of the dirty oil. The groove may have any suitable form provided that the edge of
the groove scrapes the shaft in motion and thus removes the oil, while the groove
conducts it to the outlet, away from the bearing. In order to increase the efficiency
of the oil removing device there may be placed within the groove a V blade Ď
Figs. 3 4 and 5. This blade acts as an effective scraper which is kept in contact with
the shaft by gravity. Instead of the groove there may be employed a V shaped
plate D Figs. 67 and 8 which may be inserted in the hollow of the cap so as to
embrace the upper part of the shaft, and operates in the same manner as the devices
before described. The devices for removing the dirty oil may be placed above, below
or at the side of the bearing as may be found most convenient. The removal of the
dirty oil may be assisted by bevelling the edge of the blade to a greater or less extent.
In order to secure more effective contact between the blade and the shaft, a spring
such as R Fig. 6 may be inserted betwen the blade and the cover. The triangular or
V form of the blade or scraper forces the oil to follow the direction indicated by the
arrows Figs. 3 and 6 along the scraping edges to the outlets S whence it escapes from
the bearing.
Having now particularly described and ascertained the nature of the said Inven-
tion and in what manner the same is to be performed as communicated to me
by my foreign correspondent, I declare that what I claim is :-
(1) In a Lubricator; a mass of granulated metal, shot or like material; sub-
stantially as and for the purpose hereinbefore described.
(2) The construction and arrangement of a lubricating device, substantially as and
for the purpose hereinbefore described.
