Improvements relating to the Lubrication of Bearings for Shafts
and the like.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, do hereby
declare the nature of this invention to be as follows:-
This invention relates to a device, by means of which the lubricating receptacles
provided upon the shaft-bearings can be regulated, or set in and out of action,
from a central station, in order to adapt the admission of the lubricating material
to the actual requirements, and to obviate the necessity of giving special attention
to the bearings during the working and the attendant danger.
In carrying the invention into practice a movable part, which is adapted to
traverse a certain distance in a certain time, serves as the central station. With
this part is connected an intermediate link, which may for instance be a rod, wire,
or cord stretched and kept tant by means of a spring, and which takes up the
movements of the movable part. With this interinediate link is or are connected
the pressing piston or pistons of the lubricating receptacles in such a manuer, for
example suspended from the intermediate link, that the movements performed by
the aforesaid movable part will be transmitted to the piston or pistons which
conduct the lubricating material to the bearings in accordance with their
movements.
When the lubricating receptacles have become empty it is expedient to interrupt
the working and return the said movable part back to its original position, the
lubricating receptacles being filled again.

COMPLETE SPECIFICATION.
Improvements relating to the Lubrication of Bearings for Shafts
and the like.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, 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 :-
This invention relates to a device, by means of which the lubricating receptacles
provided upon shaft bearings can be regulated, or set in and out of action, from a

page_text: central station, in order to adapt the admission of the lubricating material to the
actual requirements, and to obviate the necessity of giving special attention to the
bearings during the working and the consequent danger of such attention.
In carrying the invention into practice an operating device, one part of which is
adapted to traverse a certain distance in a certain time, is located at a central
station. With this traversing part of the device is connected a rod, wire, chain,
cord or the like stretched and kept taut by a spring or like means so that it
partakes of the movements of the operating device. This chain or cord is
connected through wheels with the pistons of the lubricating receptacles in such a
manner, that the movements of the operating device will be transmitted to the said
pistons which by dipping into the lubricating receptacles force the lubricant into
the bearings in accordance with their movements.
In order that the invention may be more clearly understood we have shown
diagrammatically the general arrangement of actuating parts employed in carrying
out the invention.
The aforesaid operating device may be actuated from the shafting to be
lubricated by any suitable means, or it may be automatically set in or out of
action by a separate motor.
In the present example the operating device is formed by a screw spindle A to
which is connected a rope b guided by pulleys and passed once around the
wheels ee..... from the arbors of which are suspended by means of chains or
cords ii... the pistons 9 9... of the lubricating receptacles ff... carried by the
shaft bearings k k... On the arbors of the wheels e e are preferably arranged
drums ele
of a comparatively small diameter compared with that of the
wheels ee..., so as to form a differential gearing which transmits the motion
imparted to the chain or rope b uniformly but in a small degree to the
pistons gg. Motion is imparted to the chain or rope b with the aid of a
weight c or by means of a spring where as the speed at which the chain b is
allowed to move, depends upon the speed of rotation of the screw spindle A.
When the wheels e e are allowed to turn in the direction of the arrow under the
action of the weight c or its equivalent the pistons g g descend by their own weight
into the lubricating receptacles fj provided with telescopically sliding
covers d d... in such a manner that the lubricant is forced either directly or
through a tube h' into the oil-conduct h of the bearings k k...
When the lubricating receptacles have become empty, the spindle A may be
returned to its lowest position by means of a cranked bandle placed upon the
square of the driving shaft a.. of the operating device whereby the pistons gg....
are moved back to their original positions, so that the lubricating receptacles may
again be filled, which is preferably performed while the apparatus is at rest.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to me
by my foreign correspondents, I declare that what I claim is :-
1. The herein described device for lubricating bearings for shafts and the like
characterized by a number of lubricating receptacles connected with each other
and all connected with an operating device, through a chain cord or the like
substantially as and for the purpose set forth.
2. In a lubricating device the combination of a number of lubricating
receptacles (), pistons (g), differential gearings (e e¹) and an operating device all
connected together and with each other, substantially as and for the purpose set
forth.
