I, HERBERT JOHN HADDAN, of 67 Strand, in the City of Westminster, Civil
Engineer, do hereby declare the nature of said invention for IMPROVEMENTS IN
BEARINGS AND AXLES, a communication to me from abroad by Lorenz Leirer of
Budapest, in the kingdom of Hungary, Manufacturer, and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement -
This invention has for its object to secure a more noiseless and easy locomotion
of vehicles which have the wheels rigidly connected to the axle, and consists in
making the latter to turn in journals or bearings expressly constructed for this
purpose. The drawings annexed serve to illustrate the mode of performing the
improvements.
Fig 1 represents the upper part of a journal or bearing constructed according to
this invention.
Fig 2 represents the bottom part of the same, both in side view.
Fig 3 is a view from below of the upper part, and Fig 4 is a view from above of
the lower part of the journal.
Figs 5, 6 and 7 show separate parts of an axle.
Fig 8 shows the same united.
The figures are drawn in different scales.
On the bearing proper or inner face a of the journal-halves A, Fig 1 and B Fig 2
is arranged an annular recess or groove b (Figs 3 and 4) of semicircular section
intended to receive and form a passage for the grease or lubricating oil, which is
introduced at the opening b¹ (Fig 3) above which is arranged a lubricating fountain
tank or chamber c (Fig 1) the cover of which is held down and secured in a closed
state by means of a spring catch c'. It is understood however that the lubricating
fountain may be arranged at any other desirable place and that the device for
closing the same may be constructed in any other suitable manner.
The inner face a of the journal is provided with an annular offset or recess at &
and d¹ (as shown in Figs 3 and 4) which recesses or enlarged flanges serve to keep
the dust off the lubricating oil. These rings d and ď¹ surround the axle uniformly.

page_text: The lower part B of the journal is provided with two projecting parts e and e¹
(Fig 2) which enter into the corresponding recesses fand f¹ of the upper part A
(Fig 1) and in this manner the two parts of the journal are rigidly connected. It
will be understood however that these lugs or projecting parts e e¹ may be arranged
on the upper part A, that they may have any other desirable shape and that they
can even be dispensed with.
The journals may be connected with the vehicle in different manners, for
instance by means of lugs cast on to the journals, by grooves, screws or by any
other devices.
The axle g (as put together and shown on a smaller scale in Fig 8) is provided
at those points which correspond to the journals, with annular rings or flanges p
and p¹, with faces h h¹ lying between, for fitting exactly to the inner faces a of the
journals.
The axle is also provided with projecting rings i i¹ (of semicircular section)
which fit into the annular grooves b of the journals; in this manner a displacement
of the axles in the direction of the longitudinal axis is prevented. It will be
understood however that the projecting rings as well as receding parts or
grooves b may be increased in number and that also the projecting rings i and i¹
as well as the grooves b may be dispensed with entirely.
The hubs of the wheels are of square shape for the sake of rigid connection
with the axles; this rigid connection however may be attained in any other well
known manner,
The axles generally consist of two parts as represented in Figs 5 and 6 (but
may be constructed also in one part). These two parts are capable of turning
independently one from the other.
One part of the axle ( Fig 5) ends at one side on the boss of the wheel and
generally formed as shown in Fig 8 and at the other end is provided with the head
piece, which, when the two parts of the axle are connected enters the corresponding
cavity or bore of m shown at Fig 6.
The connection or locking of both parts of the axle is effected by means of the
fixed or movable coupling-box or ring 'n Fig 5 which may be provided with threads,
teeth or the like and which is screwed into the female thread n¹ at the end of the
part m and prevents the entrance of dust.
This threaded coupling-ring sits loose upon the part k and after connection with
the part m is fastened to this by means of one or several screws r as shown. Thus
the two parts are connected together and protected against displacement in the
direction of the longitudinal axis whilst at the same time each of the parts is
allowed to rotate independently of the other.
с
The lubricating of the parts of the axle lying one inside of the other may be
effected by means of any desirable and suitable material which is introduced to the
lubricating passage u through the opening u¹ which may be closed by a screw as
shown.
An axle thus put together and provided with a sliding coupling ring is shown at
Fig 8.
It is understood that the connection of the parts k and k¹ may be effected in
other ways.
Either the front or rear axle may be constructed in one or two parts; if of
two parts, these may be separate or may be connected as shown in Fig 5,6,7
and 8.
The indentation o Fig 7 serves for grasping the coupling clutch on tightening
or loosening the same.
Having now particularly described and ascertained the nature of said inven-
tion and in what manner the same is to be performed, I declare that what
I claim is
1. The arrangement and use of bearings in two parts A and B, provided with
an inner bearing face a, the dust preventing, protecting case d d', lubricating

page_text: passage band fountain c. The parts A B are connected with each other by
means of lugs e, el entering recesses f, f¹, substantially as and for the purpose
described.
2. The construction of axles adapted to run in the journals shown and described,
or any others, provided with the annular projections or flanges p, p¹, (receding
parts h, h) and rounded flanges or collars i, adapted to run inside of the
lubricating passage b of the journals, substantially as and for the purpose
described.
3. The arrangement of rotating axles (in one or two parts) for the purpose of
securing a more noiseless and easy locomotion of the same, whereby those axles
consisting of two parts may be connected with each other or not, substantially as
and for the purpose described.
4. In axles composed of two parts the connection of both parts, by means of a
cavity or bore m arranged at one part and provided with lubricating passage and
a headpiece of the other part fitting into the bore above described and of a
sliding coupling ring n, Fig 5, capable of being fixed by means of a screw r,
substantially as and for the purpose described.
