virtue of a Deed of Assignment, dated the Fourth day of May, One
thousand eight hundred and seventy-six, and registered in the
Register of Proprietors in the Great Seal Patent Office duly vested
in-me:
And whereas, I, the said August Osenbrück, since the filing of the
said Specification have ascertained that certain parts of the said In-
vention were known before the date of the said Patent; also that the
clearness of the said Specification is impaired in various places by
clerical and translator's errors; also that the Drawings in some few
places somewhat vaguely indicate the parts described, some reference
letters being, also omitted.

which thus loses its limpidity, and is by adhesion drawn to the outer
surface of the disc, where it escapes by leakage; the arrangements
there shown also possess many other practical disadvantages; I am also
aware that J. B. G. Piret, in the Specification of his Patent, No. 647
A.D. 1862, describes the forming of the axle journal with circular
grooves for the alleged purpose of preventing the waste of oil by leakage,

To alter the present third claim into the second as follows:-" Second.
The conical oil chamber employed for loose pulleys or other objects
running loose on shafts or studs in combination with the tube R at its
largest end, all constructed and operating as here described and as shown
on the accompanying Drawings."
To alter the present fourth claim into the third, videlicet, "Third. The
axially bored shank or journal into which the oil is forced from the

The lubricating box A of the journal in which the small tube R.empties
or discharges its contents when arranged and combined, as shown and
described."
To alter the present sixth claim into he fifth, videlicet, "Fifth. The
arrangement here described and shown, by means of which the
lubricating oil after having passed the journal returns to the centrifugal
cup, and."
To make the present seventh claim into the sixth,. videlicet,," Sixth.
The grooves in the journal or in the axle for avoiding the: gradual' waste
of the lubricating oil when arranged and operating, substantially as here
described and shown."
And, lastly, to strike out the present eighth and ninth claims.
And the said Specification when altered: and disclaimed reads as
follows:
This Invention refers to the employment of centrifugal and adhesive
action or power in connection with grease or oil boxes for the purpose of
keeping up a constant circulation and re-use of the lubricating matter.
For each bearing of horizontal and vertical shafts or spindles to be
lubricated there is in close contact with it a metal, glass, or earthenware
circular cup fixed to the shaft, and to one end of the bearing is fixed a
bent pipe, one end reaching into the cup to its greatest internal diameter
and its other end communicating by means of a hole through the
bearing with the grease or oil box.
The grease box and cup. both contain lubricating matter, and, when.
revolving motion is given to the shaft the cup as it revolves spreads, the
grease over its greatest internal circumference, from whence by the
centrifugal action of the revolving cup it is taken up by the bent pipe.
and returned to the grease box, and after the lubricating matter has
again passed from the box to the bearing it is again returned to the box,,
and so on continuously.
When the grease box forms part of the journal or bearing there may
be one, two, or more bent pipes in connection with passages for allowing
the circulation to be kept up by the action of the revolving cup.

page_text: For pulleys and other articles revolving on shafts or studs, either
stationary or at times in a state of rest, the pulley itself is fitted or
formed with a centrifugal revolving cup, there being a grease or oil
chamber formed in the boss and kept tight by plates, packing, and
screws, and at the ends of the pulley within the packings there are one
or more bent pipes and passages for enabling the lubricating matter to
be in constant circulation with the shaft and with the grease chamber.

thrown against its inner circumference, where it is caught by the mouth
of the bent pipe R and forced up to the oil chamber A, whence it flows
down the journal lubricating same, and finally drops into the cup Sto
be again caught and raised to the oil chamber A, and so on.
Figure 2 represents a bearing for a horizontal shaft. The cup S has
at a and b two collars forming annular gutters destined to convey the

page_text: through which it returns at the spout f into the cup S. This con-
struction of axle bearings can also be employed for grooved shafts.
In Figures 5 and 6 loose pulleys are represented for horizontal and
vertical shafts respectively. On the vertical shaft E, Figure 6, is placed
a ring Z, shrunk on hot or soldered on with tin, which ring is turned out
below, and in which the receiving tube R is fastened. The cover D
represents the centrifugal cup s, and is provided with the annular
groove C, the ring a fitting in the grooving of the ring Z, and in the
centre of the shaft in the direction of the axis there is a hole L closed
at the end by a screw k and leaden washer, the hole communicating
both with the receiving tube R and with several lubricating holes
opening into a groove m, m, in the shank. The effect of the arrange-
ment will be understood by what is said in the beginning.
In Figure 5, the construction for horizontal studs or shafts, the shank
is bored in the line of the axis, and closed at the end by a screw k, and
the receiving tube R is placed in a female screw M, which secures the
pulley from running off, and in front of this nut M there is a counter-
nut M. The tube R communicates by the annular groove n, and by
the hole 1 opening or discharging radially into it, with the centre hole L,
from which several (here 4) holes go to the surface of the shank or
journal, or, better, to an oil groove m in it. The centrifugal cup K, K,
forms here a cone chamber, the largest diameter of which is at the small
tube R. By the partition or disc T, in which the metal bush h of the
pulley is fastened by a screw, the cone chamber is divided in two
parts, which are brought in communication together by a suitable
number (here 6) of large holes placed close to the exterior wall of the
chamber. The pulley is closed oil-tight on both sides by means of
inserted leathern or leaden rings, and covers D and k screwed on the
exterior cover D encloses the shank or journal end, and the concentric
triangular grooves at avoid the gradual escape of the oil on the stud
or shaft. The disc or partition T is provided with lubricating material
by the hole 6 screwed through the pulley web, and closed oil-tight' out-

I, FRANK WIRTH, of the Firm of Wirth and Company, Patent Agents,
residing at Frankfort on the Maine (Germany), do hereby declare the
nature of the said Invention for "IMPROVED CIRCULATING LUBRICATORS FOR
JOURNAL BOXES AND BEARINGS OF QUICKLY REVOLVING SHAFTS, SPINDLES, AND ALSO
FOR REVOLVING PULLEYS AND SIMILAR OBJECTS," a communication from August

This Invention consists in the employment of centrifugal action or power in
connection with the grease or oil boxes, for the purpose of keeping up a con-
stant circulation of the lubricating matter, and thereby prevent its loss and use
it up to the uttermost.
1
i
For each bearing of horizontal and vertical shafts or spindles to be
lubricated there is in close contact with it a metal, glass, or earthenware
circular cup fixed to the shaft, and to one end of the bearing is fixed a bent pipe,
one end reaching into the cup to its greatest internal diameter, and its other
end communicating by means of a hole through the bearing with a pipe fixed
to the grease or oil box.
The grease box and cup both contain lubricating matter, and when revolving
motion is given to the shaft the cup as it revolves spreads the
grease over (its greatest internal circumference, from whence by the centri-
fugal action of the revolving cup it is taken up by the bent pipe and returned
to the grease box, and after the lubricating matter has again
passed from the box to the bearing it is again returned to the box, and so on
continuously.
When the grease box forms part of the journal or bearing there may be one,
two, or more bent pipes in connection with passages for allowing the circulation
to be kept up by the action of the revolving cup.
For pulleys and other articles revolving on shafts or studs, either stationary
or in a state of rest, the pulley itself performs the centrifugal action of the
revolving cup, there being a grease or oil chamber formed in the boss, and kept
tight by plates, packing, and screws, and at the ends of the
pulley within the packings there are pipes and passages for enabling the lubri-
cating matter to be in constant circulation with the shaft and
grease chamber, and it is evident the centrifugal action of a cup, pulley, or
other vessel containing lubricating matter can be applied to a great variety
of combinations for keeping up the circulation.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent; filed
by the said Frank Wirth in the Great Seal Patent Office of on the 11th
March 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRANK
WIRTH, of the Firm of Wirth and Company, Patent Agents, residing at Frank-
fort on the Maine (Germany), send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of September, in the year
of our Lord One thousand eight hundred and seventy-three, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Frank Wirth, Her special licence that I, the
said Frank Wirth, my
and
executors, administrators,
assigns, or
such others as I, the said Frank Wirth, my executors, admini-
strators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within
the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVED CIRCULATING
LUBRICATORS FOR JOURNAL BOXES AND BEARINGS OF QUICKLY REVOLVING SHAFTS
SPINDLES, AND ALSO FOR REVOLVING PULLEYS AND SIMILAR OBJECTS," a com-
munication from August Osenbruck, a person residing at Hemelingen (Ger-
many), upon the condition (amongst others) that 1, the said Frank Wirth, my
executors or administrators, by an instrument in writing under my, or their,
or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said Frank Wirth, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, reference being had to the Figures on the accompanying Sheet of
Drawings, and to the letters of reference marked thereon, that is
to say:
This Invention consists in the employment of centrifugal action or power
in connection with the grease or oil boxes, for the purpose of keeping up a

page_text: UT the picating matter, and thereby prevent its loss and
use it up to the uttermost.
For each bearing of horizontal and vertical shafts or spindles to be lubri-
cated there is in close contact with it a metal, glass, or earthenware circular
cup fixed to the shaft, and to one end of the bearing is fixed a bent pipe, one
end reaching into the cup to its greatest internal diameter, and its other end
communicating by means of a hole through the bearing with a pipe fixed to
the grease or oil box.
The grease box and cup both contain lubricating matter, and when revolving
motion is given to the shaft the cup as it revolves spreads the
grease over its greatest internal circumference, from whence by the centri-
fugal action of the revolving cup it is taken up by the bent pipe
and returned to the grease box, and after the lubricating matter has again
passed from the box to the bearing it is again returned to the box, and so on
continuously.
When the grease box forms part of the journal or bearing there may be
one, two, or more bent pipes in connection with passages for allowing the cir-
culation to be kept up by the action of the revolving cup.
For pulleys and other articles revolving on shafts or studs, either either
stationary or in a state of rest, the pulley itself performs the centrifugal action
of the revolving cup, there being a grease or oil chamber formed in the boss,
and kept tight by plates, packing, and screws, and at the ends of the pulley
within the packings there are pipes and passages for enabling the lubricating
matter to be in constant circulation with the shaft and grease chamber, and
it is evident the centrifugal action of a cup, pulley, or other
vessel containing lubricating matter can be applied to a great variety of com-
binations for keeping up the circulation.
On the accompanying Sheet of Drawings Figs. 1 and 2 are views represent-
ing axle boxes or bearings for vertical and horizontal shafts provided with
my improved lubricating apparatus.
Fig. 3, a longitudinal section of a divided box or bearing having a cap;
Fig. 4, a transverse section at the line A, D, Fig. 3.
Fig. 5 represents a loose pulley for horizontal arbors and shafts.
Fig. 6, a loose pulley for vertical arbors and shafts.

page_text: Fig. 7, an axle box for wagons having a circulatory lubricating
apparatus; Fig. 8, a transverse section of the same at the line A, B, in
Fig. 7.
Fig. 9 is a view of another axle box; and Fig. 10, a plan of one of its
parts.
In Figs. 1 and 2 representing the axle boxes or bearings for vertical and
horizontal shafts, the bearing for the vertical shaft will be understood by the
Drawing and some further explanation.
To understand Fig. 2 the following may be added:-The cup S has at a
and two collars destined to convey the oil running down the
sides or walls during the rest or standstill to the lowest place, and all cups
for horizontal shafts have such collars. The annular scors at 1, 2, 3, 4, as
well as the groove n in the axle box communicating or discm-
boguing by means of a long long groove R to the cup S are arrangements
proved practical for avoiding the creeping away of the oil, and the
tube R is introduced into the oil box A by a packing of cork or other suit-
able material.
Figs. 3 and 4 represent a divided box having a cap in which the small
tube R exactly fits in an extension of the annular projection, and is held by
the small screw s, and this tube R communicates with the right angled bore
or passage leading to the grease box A.
In order to avoid a spouting spurting under the cover D of the oil box at
the beginning of the rotation of the cup, especially after a long rest or stan.i-
still, when it contains the whole lubricating material, a sliding sheet z by
means of a pin is placed above the hole 1.
From A three or more holes or bores lead through the cap piece and the
cup in a long groove of the latter, by which means the grease is equally
diffused over the under part of the shaft, and in order that no lubricating material
may come beyond this part of the shaft some annular screws are
cut in at each side of it, and grease coming in here is thrown off and falls dowa
in drops.
The axle box is a little longer than the bush bed, and contains on each side
a composition x, which in the lower half of the bearings is a little larger than
the channel receiving the cap piece. The purpose of this arrangement is to
receive the grease running from the grooves in the compositions

page_text: x, x, and both the compositions are united by the groove y, which is skinned
by a sheet against the composition.
The tube R is placed at a saddle e projecting at the cap piece, taking up
the oil falling down in drops during the activity of the apparatus, and deliver-
ing it to the semicircular cup d placed at the lower bush, through which it
returns at into the cup S. This construction of axle bearings can also be
employed for grooved shafts.
In Fig. 5 and 6 loose pulleys are represented for horizontal and
vertical shafts.
On the vertical shaft, Fig. 6, is fixed a heated ring z, or a ring soldered
with tin, which is turned out below, and in which the receiving tube R is
fastened. The cover D represents the centrifugal cup, and is therefore pro-
vided with the annular groove C, the circular composition fitting
in the grooving of the ring z, and in the centre of the shaft in the direction of
the axis there is a hole L, closed at the end by a screw and leaden washer,
the hole disemboguing or communicating both with the receiving
tube and several lubricating holes opening into a groove m, m, of the leg,
and the effect of the arrangement will be understood by what is said in the
beginning.

In Fig. 5, the construction for horizontal arbors or shafts, the leg is bored
in the line of the axis and closed before the end by a screw, and the receiving
tube R is placed on
female screw
m, securing the pulley from
running off, and before this screw there is a counterscrew. The tube R com-
municates by the annular groove n, and by the hole 1 opening or disemboguing
radially in it, with the counterhole from which several (here 4)
holes go to the surface of the leg or journal, 01 better to an
oil groove in it. The centrifugal cup K, K, forms here a cone, the largest
diameter of which is at the small tube R. By the disk T in which the metal
box B of the pulley is fastened by a
screw, the cone is divided
in two parts, which are brought in communication together by a
corresponding number (here 6) of large holes placed close to the exterior
wall.
The pulley is closed oil-tight on both sides by means of inserted leathern
or leaden rings and covers screwed on, and the exterior covers also contain
the leg or journal end, and the concentric triangular grooves at avoid
the creeping away of the oil on the arbor or shaft.

page_text: The disk is provided with lubricating material by the hole b screwed
through the plate, and closed oil-tight outward by a screw.
The effect of the arrangement is the following:-If the disk rotates, the
oil in the conical groove having come during the standstill to the lowest point
runs to the largest diameter of the small tube R, it is pushed by this into the
central hole, and comes from here through the holes 2, 3, 4, 5,
to the leg to be greased, on which it diffuses to the left and
right, in order to run off again into the conical groove, and to recommence
here its circulation.
In Fig. 7 and 8, representing axle boxes for waggons with circulatory
lubricating apparatus, the axle box case consists of an upper and under half.
Before the socket of the branch the case forms a cylindrical chamber, which
is closed tight on the upper bush by a cover by means of inserted leathern
or lead disks, and this chamber contains the centrifugal cup 0,
fastened concentrically by means of a screw and pin on a top Z
of the leg top.
The fastening can also be effected in another manner, for instance, by par-
tially entering the cup disk into the tap and fastening by screws.

The cup consists of two parts, first, the oil box proper O, made of brass,
sheet iron, or tempered cast iron; and secondly, the disk S carrying this
reservoir. The intention of this division is to allow an easy fitting together
and taking the cup asunder. The receiving tube R is made fork-like, by which
it is enabled to go forward and backward.
In order to lead the oil running off at the receiving tube into the cup,
exactly as in the divided bush, the saddle c is arranged, which delivers it into
the semicircular cap d of the under bush.
Both arrangements receive at the same time the grease thrown off from the
tap.
I
In the grease reservoir A, the cover D of which bears the carriage spring
and which closes it oil-tight above by inserted sheet lead, there are three
tubes 1, 2, and 3. The one of them 3 is provided with a sucking wick,
whereas the two others raise to a certain extent the bottom of the grease
reservoir, and communicate directly with it. The purpose of this arrangement
is to lead, after a long standstill, oil to the sucking tube the quantity of which
is determined by the height of the two small tubes 1 and 2
placed above the bottom of the lubricating chamber. Without this
arrangement, in a slow motion for instance, in ranging trains after

page_text: a long standstill, a grinding of the tap with the cup might take
place, and the arrangement allows a deposit of any ground refuse
or pieces of metal parts out of the oil of the bottom of the lubricating
chamber.
The connexion of the two halves of the bushes is effected by four loop
screws with female screws, the middles of the bushes fitting the
groove and channel. The two leading grooves N, N, are only placed at the
upper half of the bush because otherwise one cannot take off easily
the under bush. The felt sheaves closing the bush to the wheel side, and con-
of
sisting each
two halves, are constructed as
from
ordinarily
inserted sheet with two exterior fell sheaves, and each half is pressed against
the axis by a spiral spring placed in the middle, and by means of
the grooves of the arbor behind the tap at K the creeping away. of the oil is
avoided.
The lubricating oil is poured in through an opening closed with a screw in
the cover of the grease chamber.
The working and effect of the arrangement is exactly the same as already
described in the divided bush.
Fig. 9 shows a modified construction of an axle bearing in which the oil
chamber A is circular, and has in the middle a second annular opening with
a support a, (I, on which rests a brass disk (Fig. 10), with two
wick boxes and a hole in the middle, and the said wicks reach into the
annular space of the lubricating chamber, ลูก that oil flowing over
comes directly into effect, and at the saddle c, c, there are on both sides the
fastened caps f, f, serving to receive the oil thrown off by the
attack.
The connexion of the lubricating cup O with the plate S is effected by a
kind of bayonett shutting, as seven pins s are bored in the rim, whereas in
the disk K compositions corresponding to the disk are placed
which let the pins pass. By turning the cup on the disc a little off, and
finally fastening the screw p both parts are closely united. The annular pro-
jection of the plate r avoids શૈ sneaking" of the oil falling in
