I, ARNOLD BUDENBERG, of Southgate, Manchester in the County of Lancaster,
Mechanical Engineer, do hereby declare the nature of said Invention for "A NEW
OR IMPROVED METHOD OF AND APPARATUS FOR FILLING LUBRICATORS," a com-
munication to me from abroad by William Noll, of Minden, in the German Empire,
to be as follows:-
This invention relates to the method of charging lubricators with semi-solid or
consistent grease and to apparatus employed for that purpose.
In order to charge such lubricators in a more convenient and expeditious manner
I use a pump communicating at one end with the lubricator, while the other end is
open towards the atmosphere.
The piston of this pump has a piston rod projecting through the open end of the
pump-barrel and provided with a series of holes for the reception of a pin which
connects the rod with a hand lever pivoted to a bracket or link secured to the
pump-barrel.
In using the apparatus the piston is drawn out of the pump barrel, the latter
filled with grease and the piston placed on the top of the grease. The lubricator to
be charged is then screwed or otherwise secured to the upper end of a pipe
communicating with the closed end of the barrel, the hand lever is then connected
with the piston rod by passing a pin through the said lever and the lowest hole of
the piston rod, and the piston is pressed into the barrel for a distance sufficient to
fill the lubricator with the grease pressed out at the opposite end. The lubricator
thus charged is then removed and replaced by an empty one, the connecting pin is
drawn out of the hand lever, the latter is lifted and connected with the piston rod
by inserting the pin into the next hole, after which the charging of the lubricator
proceeds as described.
The pump barrel is preferably placed vertical, with the open end at the top, and
instead of providing the piston rod with holes, any other suitable device may be
adopted for coupling the hand lever with the piston rod at different beights, for
instance a toothed rack or a friction coupling.

page_text: I ARNOLD BUDENBERG, of Southgate, Manchester, in the county of Lancaster,
Mechanical Engineer, do hereby declare the nature of said Invention for "A NEW
OR IMPROVED METHOD OF AND APPARATUS FOR FILLING LUBRICATORS," a com-
munication to me from abroad by William Noll, of Minden, in the German Empire,
and in what manner the same is to be performed to be particularly described a
and ascertained in and by the following statement :—
This invention relates to a method of charging lubricators with semi-solid or
consistent grease or lubricating material, and to apparatus employed for this
purpose.
In order to charge such lubricators in a more convenient and expeditious manner
than that usually adopted, I use a pump communicating at one end with the outlet
pipe or bottom of the lubricator or lubricators and containing a piston the rod of
which extends through the opposite end of the pump barrel and is adapted to be
set in motion by hand..
This may be effected by means of a hand lever pivoted at one end to a bracket
or link secured to the pump barrel and connected with the piston rod by a
removable pin passing through the lever and one of a series of holes formed in the
piston rod for connecting it with the lever at different heights.
Instead of providing a special hand lever, a handle may be formed or mounted
on the end of the piston rod; or the piston rod may be converted into a screw
spindle passing through a screw nut secured to the cover of the pump, so that by
turning the said nut the spindle may be screwed in and out and thereby the
desired axial motion imparted to the piston, the screw nut being formed into a
small hand wheel for adapting it to be turned by hand; or the spindle may be made
to screw through the piston or through a nut attached to the same, and carry a
small hand wheel outside the cover of the pump, so that, by turning the band
wheel, the screw is turned on its axis, and causes the piston to screw itself along
the spindle; or the piston rod may be converted into a toothed rack set in motion
by turning a pinion; or any other convenient device may be employed for setting
the piston in motion.
In the accompanying drawings Fig. 1 is an elevation, Fig. 2 a vertical section
and Fig. 3 a plan of a vertical grease-pump provided with two pipe connections for
charging two different kinds or sizes of lubricators, while Fig. 2 shows a detail of
construction. Fig. 4 shows a pump provided with a hand lever for setting in
motion the piston. A is a vertical pump barrel mounted on a base plate a and
covered with a lid b secured by a sort of bayonet lock, as indicated by Fig. 3, which
is a plan after removal of the lid.
The barrel contains a piston B. This piston chiefly consists of a cup leather c,
placed between two thin metallic discs, the lower of which is also cup-shaped and
provided at its circumference with a number of radial slits, so as to form elastic
flaps d, adapted to press the leather against the wall of the cylinder. The piston
rod C extends through the lid b and carries a handle e.
.
The interior of the barrel communicates at the bottom with a pair of bent
pipes D, D, the upper ends of which are open and form a joint for the lubricators.
When not connected with a lubricator, the free end is closed by a screw plug f
The drawing shows one of the pipes carrying a lubricator E ready for being
charged, while the other pipe is closed by a plug f secured to a chain.

page_text: Fig. 2 shows a section of the open end of the bent pipe D provided with a
screw thread and ready to receive the conical outlet pipe e¹ of the lubricator E.
Any other suitable joint may, however, be used for connecting a lubricator with
the pump.
In the modified form, Fig. 4, F is a flat piston rod having a series of holes g.
The hand lever G is pivoted to a bracket or arm H and connected with the piston
rod at a convenient part of its length by a pin h passing through one of the holes
of the rod.
For filling the pump illustrated by the drawings, the piston is drawn out of the
barrel, the latter nearly filled with grease and the piston placed on the top of the
grease, after which the pump is ready for use. To charge a lubricator one of
the plugs f, is screwed off, the lubricator is screwed in its placed, and the piston
forced down by applying pressure to the handle e or the lever G, which lever has
been previously connected with the pistod rod by making use of the highest of the
holes g.
The piston forces the grease from the bottom of the pump barrel through the
bent pipe into the lubricator from the bottom of the latter. When the lubricator
has been thus filled it is screwed off and replaced by an empty one, after which the
same operation is repeated.
It is evident that the pump may be adapted to act in a horizontal or inclined
position, or that it may have one discharge opening leading to two or more branch
pipes, each of which carries a joint for a different kind of lubricators, and that the
construction of the pump may be otherwise modified without departing from the
invention.
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. The method of charging lubricators with grease, which consists in connecting
the bottom of the lubricator with the discharge pipe of a force pump containing
grease, and setting the pump in action.
2. The combination of a pump barrel having a discharge pipe provided with a
coupling or joint for the bottom or outlet pipe of a lubricator, with a movable
pump piston and a piston rod adapted to be set in motion by hand, substantially as
and for the purpose described.
3. The combination of a pump barrel having a discharge pipe provided with a
coupling or joint for the bottom or outlet pipe of a lubricator, with a movable pump
piston, a piston rod having a series of holes, and a hand lever and pin, substantially
as and for the purpose described.
