I, HEINRICH BILLETER Junior, of Aschersleben, in the Empire of Germany, do
hereby declare the nature of this invention to be as follows :—
r
The present invention relates to apparatus for automatically lubricating machinery
which apparatus is distinguished by its great simplicity of construction and certainty
of action.
The improved apparatus consists essentially in three principal parts viz. a cylinder,
a diving piston or plunger and mechanism for displacing these two parts relatively to
each other.
The cylinder is provided with a stuffing box and is closed at the lower end. The
flange of the stuffing box has a projection which moves in a groove formed in the
frame of the apparatus. Instead of this projection and groove, a longitudinal groove
can be formed in the cylinder and a pin fixed to the frame caused to engage with this
groove.
Upon the outside of the cylinder along its entire length are formed screw threads
with which a nut made in the form of a sleeve engages. This nut turns in a socket
in the frame of the apparatus, and in order that no longitudinal displacement shall
occur, the sleeve is provided at its upper end with a shoulder and at its lower end with
a nut. The said sleeve is moreover provided at the upper edge with teeth with which
the worm engages.
The said worm is firmly connected with its shaft which is supported in a block
capable of swinging at its lower end upon a pivot. The said block is secured by a
screw and lugs. If the screw is removed and the lugs turned, the block can be turned
back so far that the worm is disengaged from the teeth.
Upon the shaft of the worm on one side of the block is a lever which turns
loosely upon the shaft. A ratchet wheel is likewise loose upon the shaft with the
teeth of which wheel a pawl on the lever engages.
A flat spring is so fixed upon
the shaft by means of a nut that it must turn with the shaft. The ends of the spring
press upon one side of the ratchet wheel.
The piston of the apparatus is firmly connected at its upper end with the cross
beam of the frame and is provided with an oil cup in the bottom of which a cock is

page_text: inserted. Through the piston extends a longitudinal hole which passes through the
cock and terminates in the oil cup. A lateral opening also extends from the cock to
which opening a tubular mouth piece is joined.
A vertical shaft is supported in the base of the apparatus and is held near the
upper end by an arm. This shaft carries a hand-wheel and at the lower end has a
spur wheel which engages with the teeth of the sleeve.
The mode of action of the lubricating apparatus herein before described is as follows,
that is to say, the lever is connected by a rod, or by any other suitable means with a
to-and-fro moving part of the machine to be lubricated. Therefore during every
revolution of the machine the ratchet wheel is turned through a definite angle and
thereby also through the medium of the spring the sbaft upon which the worm is,
supposing that the resistance opposed to the rotation is not larger than the friction
between the spring and pawl, turned. The rotation of the worm shaft causes the
turning of the sleeve and this gradually moves the cylinder upwards, whereby the oil
in the cylinder is pressed through the bore of the plunger to the cock and, if this is
properly placed, through the small pipe to the part of the machine that is to be
lubricated. When the cylinder has passed up so high that the bottom of the cylinder
comes into contact with the piston the cylinder must be returned to it lowest position
and again filled with lubricating material.
No breakage can occur when the cylinder bottom comes into contact with the piston
as the spring then slides on the surface of the ratchet wheel and therefore no longer
turns the worm.
For the purpose of filling oil into the cylinder, the block holding screw is removed
and the worm is disengaged from the teeth. The cylinder can then be moved more
quickly downwards by means of the hand wheel and the gear wheel on the vertical
shaft than would be possible by turning the racket wheel back.
When moving the cylinder downwards the cock is turned so that the lateral opening
is closed, and the oil cup into which the necessary oil is poured, is in connection with
the interior of the cylinder.

page_text: I, HEINRICH BILLETER, Junior, of Aschersleben, in the Empire of Germany, 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:-
The present invention relates to apparatus for automatically lubricating machinery
which apparatus is distinguished by its great simplicity of construction and certainty
of action.
In the accompanying drawings,
Figure is a front elevation of an apparatus constructed according to my
invention.
Figure 2 is a section of the same on the line X, X Figure 1; and
Figure 3 is a side elevation partly in section on the line y y Figure 1.
The improved apparatus consists essentially of three principal parts viz. the
cylinder a, diving piston or plunger b and mechanism for displacing these two parts
relatively to each other.
The cylinder a is provided with a stuffing box a¹, and is closed at the lower end.
The flange a of the stuffing box has a projection o which moves in a groove o¹ formed
in the frame of the apparatus. Instead of this projection and groove, a longitudinal
groove can be formed in the cylinder and a pin fixed to the frame caused to engage
with this groove.
Upon the outside of the cylinder a along its entire length are formed screw threads
with which a nut d made in the form of a sleeve engages. This nut turns in the
socket e in the base e¹ of the apparatus, and in order that no longitudinal displacement
shall occur the sleeve is provided at its upper end with a shoulder and at its lower end
with a nut d'. The said sleeve is moreover provided at the upper edge with teeth d²
with which the worm f engages.
The said worm is firmly connected with its shaft which is journalled in a block n
capable of swinging at its lower end upon a pivot m which is supported in lugs on
the base e.
The said block n is secured in position by the nut on a screw attached to the base.
If the nut is removed the block n can be turned back so far that the worm f.is
disengaged from the teeth d².
1.
Upon the shaft of the worm f, on one side of the block n, is a lever h, which can
turn loosely upon the said shaft. A ratchet wheel y is likewise loose upon the shaft
with the teeth of which a pawl h¹ on the lever h engages. A flat spring p is so fixed
upon the shaft by means of a nut p¹ that it must turn with the shaft. The ends of
the spring press upon one side of the ratchet wheel g.
The piston 6 of the apparatus is firmly connected at its upper end with the cross
beam of the frame and is provided with an oil cup r in the bottom of which a
cock c is inserted.

page_text: In the piston is formed a longitudinal holes which extends through the cock c and
terminates in the oil cup; a lateral opening also extends from the cock c to which
opening the tubular mouth pieces is connected.
A vertical shaft k is supported at its lower end in the base of the apparatus and is
held near the upper end by an arm This shaft carries a hand-wheel k¹, and at the
lower end is provided with a spur wheel i which engages with the teeth d² of the
sleeve d:
The mode of action of the lubricating apparatus hereinbefore described is as
follows that is to say the lever his.connected, by a rod, or by any other suitable
means with a part of the machine to-be lubricated; having a to-and-fro motion.
During every reciprocation of the lever the ratchet wheel is turned through a
definité angle, and thereby also; through the medium of the frictional spring p the
shaft upon, which the worm is turned provided that the resistance opposed to
the rotation is not larger than the friction between the spring p and the pawl h.
The rotation of the worm causes the sleeve d to turn and this gradually moves
the cylinder a upwards, whereby the oil in the cylinder is pressed through the bore s
of the plunger to the cock c, and, through the small pipe s² to the part of the
machine with which it is connected. When the cylinder has risen so high that the
bottom of the same comes into contact with the piston the cylinder must be returned
to its lowest position and again filled with lubricating material.
No breakage can occur when the cylinder bottom comes into contact with the
piston as the spring p then slides on the surface of the ratchet wheel g, and therefore
no longer turns the worm f.
For the purpose of filling oil into the cylinder, the screw is removed, and the
worm is disengaged from the teeth d.. The cylinder can then be moved more
quickly downwards by means of the hand wheel k¹ and the gear wheel, i on the
vertical shaft than would be possible by turning the ratchet wheel back.
When moving the cylinder downwards the cock c is turned so that the lateral
opening is closed, and the oil cup, r into which the necessary oil is poured, is in
connection with the interior of the cylinder.
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
First. In lubricating apparatus the combination of the piston 6 provided with a
longitudinal passage; the cylinder a adapted to be moved towards the said piston by
means of a thread cut upon its outer periphery and a nut d, the turning of the said
cylinder being prevented by a longitudinal groove and a pin engaging with the said
groove or by a projection o engaging with a groove o¹, a worm f acting upon the
nut d, and the ratchet wheel g, all for the purpose of pressing the lubricant through
the said longitudinal passage in the piston, essentially as described and represented.
Second. In the apparatus characterized in the first claiming clause, the arrangement
of a spring p firmly connected with the worm shaft, and sliding upon the ratchet
wheel g when the resistance becomes too great, essentially as described and represented
for the purpose of preventing breakage when the bottom of the cylinder impinges
against the end of the diving piston.
