IMPROVEMENTS IN SELF LUBRICATING BEARINGS FOR SHAFTS OR AXLES to be as follows
Year: 1884

page_text: I JOHN THOMAS CARR, of Bagillt, in the county of Flint, North Wales do
hereby declare the nature of the said invention for "IMPROVEMENTS IN SELF
LUBRICATING BEARINGS FOR SHAFTS OR AXLES to be as follows:-
»
This invention relates to improvements in self lubricating bearings suitable for
the shafts or axles of haulage pulleys employed in collieries and for other shafts or
axles the invention having for object to dispense with the labour and expense
connected with the present system of lubricating haulage pulleys and to obviate
risk of accident or injury arising from neglect to lubricate the pulleys or from
insufficient lubrication.
In carrying out my invention I cast or form a frame of any suitable size and
material with a box at each end instead of employing a simple frame as hitherto ;
the said boxes aro provided with suitable roller bearings secured by means of bolts
screwed into the frame so as to allow the pulley axle or shaft to bear thereon ;
I close the said boxes by means of hinged caps or covers or other suitable devices
which will effectually exclude dust or dirt which if admitted would cause the
lubricant to clog. The boxes are charged with oil or other suitable lubricant and
form reservoirs in which the lubricant is stored; by this means as the axle or shaft
revolves on the roller bearings they are kept constantly and efficiently lubricated
by the oil or other lubricant contained in such boxes or reservoirs.
By the employment of my herein before described improved self-lubricating
bearings and frame great security and economy are effected as it is practically
impossible for any accident to occur through insufficient lubrication and the lubri-
cant in the boxes or reservoirs when properly filled will last for a considerable
time: a great saving is effected as no waste of the lubricant can take place and the
lubricating bearing being automatic in its action a constant and effectual lubrication
is insured and the friction and wear are thereby reduced to a minimum.
In order to refill the boxes or reservoirs when the lubricant is nearly exhausted
it is simply necessary to lift up the hereinbefore described caps or covers on the
boxes when the lubricant can be poured or placed therein.

page_text: I JOHN THOMAS CARR of Bagillt, in the County of Flint, North Wales do
hereby declare the nature of the said invention for "IMPROVEMENTS IN SELF-
LUBRICATING BEARINGS FOR SHAFTS OR AXLES" 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 improvements in self lubricating hearings suitable for
the shafts or axles of haulage pulleys employed in collieries and for other shafts or
axles the invention having for object to dispense with the labour and expense
connected with the present system of lubricating haulage pulleys and to obviate
risk of accident or injury arising from neglect to lubricate the pulleys or from
insufficient lubrication.
In carrying out my invention I cast or form a frame of any suitable size and
material with a box at each end instead of employing a simple frame as hitherto ;
the said boxes are provided with suitable roller bearings secured by means of bolts
screwed or fitted into the frame so as to allow the pulley axle or shaft to bear
thereon I close the said boxes by means of hinged caps or covers or other suitable
devices which will effectually exclude dust or dirt which if admitted would cause
the lubricant to clog. The boxes are charged with oil or other suitable lubricant
and form reservoirs in which the lubricant is stored.
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing in which figure 1 is a side
elevation partly in section of a self lubricating bearing for shafts or axles con-
structed according to my invention and suitable for lubricating the shafts or axles
of haulage pulleys employed in collieries; figure 2 is an end elevation and
figure 3 is a plan of the same. Similar letters in both the figures represent similar
parts.
a is the frame of the apparatus and b are the boxes at each end of the frame a;
c are the roller bearings with which each of the boxes b is provided and d are the
bolts screwed into the frame and on which the rollers c revolve; e is the pulley
axle or shaft which bears on the rollers c as shewn; ff, are bosses formed, one on
each side of the rollers c; g, g are holes in the roller c, serving to admit the lubri-
cant between the bolts d and the rollers; h, h are the caps or covers hinged at i
and serving to exclude dust or dirt from the interior of the boxes b, which dust or
dirt if admitted would cause the lubricant to clog; j represents the lubricant with
which the boxes b are charged.
By these improvements as the axle or shaft e revolves on the roller bearings c
the bearings are kept constantly and efficiently lubricated by the oil or other lubri-
cant contained in the boxes or reservoirs b, and by the employment of my
improved self lubricating bearings and frame great security and economy are
effected as it is practically impossible for any accident to occur through insufficient
lubrication and the lubricant 3, in the boxes or reservoirs 6 when properly filled
will last for a considerable time; a great saving is effected as no waste of the
lubricant can take place and the lubricating bearing being automatic in its action
a constant and effectual lubrication is insured and the friction and wear are thereby
reduced to a minimum.
In order to refill the boxes or reservoirs b when the lubricant j is nearly
exhausted it is simply necessary to lift up the herein before described caps or
covers / on the boxes b when the lubricant can be poured or placed therein.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
:-
(1) In a self lubricating bearing for shafts or axles the combination with a frame
of suitable construction and having boxes or reservoirs for containing or storing oil
or other lubricant of roller bearitiga arranged to rotate in the said lubricant
substantially as and for the purposes herein before described.
(2) The improved self lubricating bearing for axles or shafts as hereinbefore
described and represented in the accompanying drawing.
