We BENJAMIN BERRY 128 College Road Bradford in the county of York Mechanical
Draughtsman and GEORGE JENNINGS and ALBERT TUTILL JENNINGS, Thornton Road,
Bradford in the county of York Machine Makers do hereby declare the nature of this
invention to be as follows.
This invention has for its object an automatic or self Lubrication of Loose pulleys
or intermediate Gearing revolving on stationery shafts, axles or fixed studs This
Lubricator consists of a circular box or boss cast or made hollow with space to contam
oil for lubricating on the center of pulley or wheel gearing, on the interior pap or
boss of pulley or wheel gearing are drilled three small holes and in the three holes of
pap and in the middle of hollow part boss containing oil are placed three split pins or
needles as lifters On the pulley or gearing revolving or turning round these lifters
will take up some of oil and supply it on to shaft axle or stud To charge the hollow
of boss with oil there is an hole drilled on the outer shell of Boss through into hollow
and when filled with oil is closed with plug or screw.

We BENJAMIN BERRY 128 College Road Bradford in the county of York Mechanical
Draughtsman and GEORGE JENNINGS and ALBERT TUTILL JENNINGS Thornton Road
Bradford in the county of York Machine Makers 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 has for its object an automatical or self acting lubrication of loose
pulley or intermediate wheel gearing revolving or rotating on stationary shafts, axles
or studs so as to ensure a more perfect, regular and economical supply of oil in the
lubrication of loose pulleys, or gearing. To obtain the said automatical or self
lubrication of loose pulley or gearing there is an improved pap or boss cast and
made in two separate parts or halves screwed & fitted together and so forming hollow
chamber, space, cavity or recess in center or middle part of pap or boss to contain a
quanuty of oil for self lubrication and has also three small holes drilled in the separate
part or half of pap or boss with needles inserted actuating as lifters at the instant of
rotation of pulley or gearing thereby giving a supply of oil to shaft, pulley-or-gearing.
for self Lubrication To supply or charge the hollow chamber of pap or boss with
oil, there is an hole drilled from the outer shell of pap or boss through into the hollow
chamber which when filled with oil is closed tightly with plug or set screw marked I
figure 2.
In order that our invention may be better understood we have hereunto appended
explanatory drawings Figures 1, 2, 3, 4, 5 & 6
Figure 1 represents an exterior plan of pulley or gearing marked A showing the
outer shell of pap or boss marked B and screwed and fitted together in halves at B1
running on Shaft, axle or stud marked D.
Figure 2 represents a front sectional elevation of pulley or gearing with fast part
or half of Boss cast with pulley marked C and separate part or half of pap or boss
marked C 1. screwed & fitted tightly together at B1 forming whole pap or boss C
& C1 with hollow chamber marked F containing a quantity of oil and drilled holes H
with needles H 1 as lifters or syphons which at the instant of rotation of pulley gives
a supply of oil to Shaft, axle or stud for self acting lubrication.
Figure 3 is a section and figure 4 is a plan of fast part or half of pap or boss cast
with pulley.
Figure 5 is a section and figure 6 18 a plan of separate part or half of pap or boss
which is screwed and fitted tightly to fast half of pap or boss at B 1.

page_text: Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what we
claim is.
First. The automatical or self acting lubrication of loose pulleys or gearing running
on stationary shafts, axles or studs.
Second. The construction of pap or boss of pulley in two separate parts or halves
screwed and fitted tightly together.
Third. Having hollow chamber formed in center of pap or boss to contain oil.
Fourth The three holes drilled in pap or boss from hollow chamber with needles
inserted actuating as lifters for the supply of oil on to shaft from the hollow chamber
containing oil at the instant of revolution of pulley or gearing.
