Year: 1887

Specification Accepted, 27th Jan., 1888
for Axle-necks on Railway Cars.
We JOHANNES LOESEWITZ of Witten, Kingdom of Prussia, German Empire,
engineer, and GOTTFRIED MAASS of Duisburg, Kingdom of Prussia, German Empire,
merchant, 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 :—
Our invention refers to an apparatus for lubricating the axle-neck of railway-
cars and for leathering the same in such a manner that no lubricating material can
escape from the bearing-box and no dust or sand can enter the same.
The apparatus
is thus constructed that at each movement of the axle neck the lubricating material
is continually conducted to and over the same and that it always remains in a
continual circulation. The lubricating is done from above through the lubricating
holes and grooves of the bearing whereby the arrangements of wicks-oil-soakers
etc. hitherto used are entirely avoided. The leathering is applied in such a manner
that it always firmly presses against the axle-neck, so that no lubricating material
can escape from the bearing box and provided with a special leather cuff so that no
dust or sand can enter the said box.
Our invention is shown on the annexed drawings in which:
Fig. 1 is a longitudinal section through a part of the bearing box ;
Fig. 2 is a cross section of the same;
:
Fig. 3 is a longitudinal section through the entire box on a smaller scale;
Fig. 4 a top view of the leathering;
Fig. 5 a section through the same on the line y of the fig. 4.
Fig. 6 is a front view of the leathering and
Fig. 7 a detail of the leathering, being applied to the groove of the box on an
enlarged scale.

The axle-neck z is provided with fine corrugations on its head a and is in gear with
a rubber-disk b, which is fixed on a pivot c of the screw-piston d. This piston d rests
in the cylindrical covers e & f which are fixed on the cylinder g by means of
screws hh, and is further provided with paddles ii & kk which rotate in the
Pre

page_text: grooves a a ẞẞ of the covers and a double thread G. G¹. At both sides of the
cover e two pins r, are fixed to the bottom of the bearing-box, over which pins
spiral springs ss are shoved, these springs forming a support for the shoulders t t'
of the cover e.
The whole apparatus is hinge-like connected to the bottom of the bearing-box B
by means of a pivot m and only rests upon this pivot and the springs, by which
means the transferring of the jolting of the axle-neck upon the apparatus is avoided
and rubber-disk b is always kept in contact with head a. The cylinder 9 has an
opening n for introducing the lubricating material, cover e being provided with a
channel o and cover with a channel through which the material is conducted
above the axle-neck by means of corresponding connecting tubes and which are
provided with valves o' p.
The leathering a is arranged in the groove B¹ of the bearing-box. This ring
consists out of a circular felts trap laid over in the middle of its breadth, thus
showing on one side a round border and on the other an angular border. In the
interior of this strap we introduce a spring-ring & being made out of hardened-steel
wire. The ends of this ring are rebent in a straight direction and the joining parts
of the same are connected together at the joint of the felt ring by means of a box or
tube c¹, being provided with a slit. This tube as also the rebent straight spring ends,
which push against the walls of the bearing-box, prevent the ring from moving in
any direction or rotating in the direction of the rotation of the axle-neck.
A leather cuff e', the ends of which lay one upon another, is fixed on the outside
of the leathering, and is, by influence of spring 6 pressed against the axle-neck so
to prevent dust or sand from entering the box.
It is very essential that the spring ring b' is arranged between the packing
surfaces of the leathering and not before the borders of the same, so that in any
wearing out the felt material always can be drawn towards the axle-neck by means
of the stretched spring ring and that it does not toss at the borders before the packing
surfaces.
The operation of the apparatus is as follows:
At any rotation of the axle-neck in the direction of arrow R fig. 2 the
rubber-disk band with it the screw piston d are rotated in the direction of the
arrow R'. The apparatus is generally surrounded by lubricating material to of its
height and at the rotation of the screw piston the lubricating material is conducted
through opening n to the cover A by means of the thread G.
The paddles i then force the lubricating material through the channel p in the
direction of the arrow R' and from here through tube above the surface of the axle
neck. Is the axle neck turning in opposite direction the lubricating material will
be conducted above the axle neck, through opening n, cover e and channel o in the
direction of the arrow L² by means of the thread G¹.
As the flowing down oil is always again collected in the bearing box a continual
lubricating of the axle neck with the same lubricating material takes place.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what we
claim is :
1) In a lubricating apparatus for axle necks of railway cars the application of a
cylinder g with opening n, covers e & f with chambers o & p and valves o p in
combination with a piston d, being provided with a double thread G G on its
outside and paddles i ikk, as herein before described.
2) In a lubricating apparatus for axle necks of railway cars the application of a
rubber-disk bon pivot c of the screw piston d in combination with the corrugated
head a of the axle neck and springs ss' as hereinbefore described.
I
:
3) In a lubricating and leathering arrangement the application of a leathering in
the groove of the bearing box, said leathering being cut sloping and the ends laid
one above another, its interior being provided with a spring ring, as herein before
described.

page_text: 4) In a lubricating and leathering arrangement for axle-necks of railway cars the
combination of the leathering with a leather cuff e', as herein before described.
5) In a lubricating and leathering arrangement for axle-necks on bearing-boxes
of railway cars the application of a continually lubricating apparatus, operated by
the axle-necks in combination with a leathering being arranged in the groove of the
bearing box and provided with a leather cuff, as herein before described.
