WILLIAM ROBERT LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings, London, "AN IMPROVED LUBRICATING APPARATUS
[A communication to him from abroad by Ernest Lucien Bucaille Junior of Paris,
France, Manufacturer]
This invention relates to an improved lubricator designed to supply, drop by
drop, the oil necessary for the lubrication of one or several parts of a machine, the
arrangement of the said lubricator being such that the drops of oil may be supplied
at any desired speed
The said lubricator comprises a fixed glass vessel from which the oil placed
therein for lubricating purposes runs through a central channel leading to two, or
several, branch pipes provided with peculiar cocks which, when turned on, only
allow a very small quantity of oil to run out, that is to say, only one drop each
time, however the quantity of oil allowed to run out may vary according to
requirements, the flow of the same being regulated, by turning in a suitable
manner the plugs of the cocks of the various branch pipes of the said lubricator.
The oil thus dropping from each cock falls through suitable cups or pipes upon
the parts of machinery which require lubrication. Another essential feature of this
invention is a top plug provided for enabling the above mentioned glass vessel to be
filled with oil, the said plug allowing the entrance of air in the central channel of
this glass vessel.
In carrying this invention into practice I provide a perforated plate upon which
is placed a glass vessel which is traversed by a central tube provided with a disc
which holds the top of the said glass vessel. The oil is poured in the upper
aperture of the said central tube and runs thence into the glass vessel, through
apertures formed laterally and at various intervals in the said central tube. When
the glass vessel is supplied with oil, cocks are turned on, whereby the oil runs out
from the glass vessel through the central tube and thence into the branch pipes
communicating with the said cocks, the number of which may vary; the plugs

page_text: of the cocks are of conical shape and are provided with grooves which allow
the oil to run out when the said grooves are placed in front of the apertures of
the above mentioned branch pipes, the oil descending along the said plugs and
falling, drop by drop, in cups, from which it is conducted by pipes to the parts of
the machine requiring lubrication.
The said cups may be fixed upon the said lubricator in any suitable manner.
When a cock is turned on more or less, a portion of the groove of the said plug
is placed in front of the aperture of the branch pipe, the quantity of oil running
from the said plug being greater or less according as this plug is turned more or
less. As the oil runs from the glass vessel it is replaced by air passing through the
plug on the top of the glass vessel and the central pipe in order to reach the upper
part of the said glass vessel.
I sometimes dispense with the grooved plugs and provide the cock with a pin
loosely introduced into the said cock, the space left around the said pin being
sufficient to allow the oil to drip therefrom.
