PROVISIONAL SPECIFICATION left by the said James Lumb at the Office
of the Commissioners of Patents on the 20th February 1882.
JAMES LUMB of Elland in the County of York Brass Founder and Finisher.
"IMPROVEMENTS IN LUBRICATORS."
This Invention relates to lubricators suitable for use in connection with the
cylinders of steam engines and the bearings or axles of heavy shafting and consists
of improved apparatus for ensuring supply and discharge of lubricant and to
improved appliances for operating the plunger or ram of the lubricator.
Lubricators constructed according to this my said Invention "comprise" &
general lubricant container or vessel as ordinary having revolving plug bored out
to receive a piston or ram for controlling and expelling or discharging the lubricant
admitted to interior of plug by way of slot cavity or recess and hole and
discharged by the said piston or ram by way of hole and slot cavity or recess the
plug is revolved by means of mitre wheels one of which also acts as worm wheel
whereby the required motion is given to the piston or ram.

" IMPROVEMENTS IN LUBRICATORS."
This Invention relates to lubricators suitable for use in connection with the
cylinders of steam engines and the bearings or axles of heavy shafting and
consists of improved apparatus for ensuring supply and discharge of lubricant and
to improved appliances for oporating the plunger or ram of the lubricator.
Lubricators constructed according to this my said Invention comprise a general
lubricant container or vessel as ordinary having revolving plug bored out to receivo
a piston or ram for controlling and expelling or discharging the lubricant admitted
to interior of plug by way of slot cavity or recess and hole, and discharged by the
said piston or ram by way of hole and slot cavity or recess The plug is revolved
by means of mitre wheels one of which also acts as worm wheel whereby the
required motion is given to the piston or ram.
Such being the nature and object of this my said Invention I will now proceed
to describe the same in detail and in order that the Invention may be fully
understood I have hereunto annexed 2 Sheets of Drawings and have marked same
with figures and letters of reference like Figures denoting like parts.
Fig: 4 is elevation of worm and bevel wheel combined.
Fig: 5 is a sectional plan of plug.
A is the ratchet wheel operated by lover as ordinary. B is the worm gearing
with the worm wheel C on the face of which is the bevel wheel c, gearing with
bevel wheel G and driving the plug F on upper end of which it is screwed. Da
stud screwed into face of wheel C its outer end being received within the slot of
the plunger E (Fig: 3) F is the inverted taper plug in which is the cavity d
supplied at cach revolution with oil or lubricant from the reservoir e by way of
inlet to the slot g and cavity d. At each revolution of the worm wheel C
the stud D raises and forces down the plunger E expelling the lubricant from the
cavity by way of the outlet h to the lower cavity K so that at each downward
movement of the plunger E a quantity of oil or lubricant equal to the quantity
taken in at the inlet is expelled at the outlet M the valve N being forced open by
the pressure put on the lubricant by the action of the plunger H is the stuffing box
filled with asbestos or other packing. J is the gland L is the bridge supporting
the worm B and forming bearing for upper portion of plunger E the bridge is
removable on withdrawing the screw P at R is a spiral spring for holding the
plug F in position within its barrel.
Having thus fully described the nature and particulars of this my said Invention
together with the manner in which the same is to be or may be performed or
carried into practical effect I would have it understood that I lay no claim to the
rachet lever wheel, oil reservoir as these aro of the ordinary construction What I
do claim is

page_text: Firstly. The general construction and combination of parts constituting the
lubricator as illustrated by Drawings and as herein described.
Secondly. The use in combination of the revolving plug F and plunger or ram E
operated by parts C. D and G as illustrated and herein described.
In witness whereof I tho said James Lumb have hereunto set my hand and
seal the Seventeenth day of August in the year of our Lord One thousand
eight hundred and eighty two.
