Improvements in Journal
I, HENRI WYSs, of 48, rue Deguingant, Levallois-Perret, France, Engineer, 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, reference being had to the accompanying drawings and to the letters and
figures marked thereon, that is to say :-
This invention relates to an improved journal box provided with rollers for
diminishing friction.
And in order that my invention may be readily understood, I will describe the
same fully with reference to the annexed drawings, in which:
Fig. 1 is a longitudinal section showing one of my improved journal boxes.
Fig. 2 is a detail thereof, to double the scale of Fig. 1.
Fig. 3 is a section on the line a, b, of Fig. 2.
Figs. 4, 5 and 6 show modifications of my box.
1 is the journal; 2 and 3 are bushings or sleeves thereon, and 4 is a shoulder
corresponding to the shape of the widest part of the bushing or sleeve 3. These
bushings or sleeves are cylindrical on the inside and slightly conical on the outside,
and can be passed, with little friction, over the journal.
5 and 6 are two bushings or liners, conical both on the interior and on the exterior,
and arranged inside an outer tube 7, on which is mounted the vehicle wheel. This
tube is coned or tapered internally so that it contracts from each end towards its
middle part.
The rollers, which-constitute-my-bearing, are indicated at 8. They are tapered
and are arranged in two series inclined in opposite directions, but so arranged that
the axes of all the rollers in either series converge to the same point of the axis of the
journal.
The outer tube 7 fits,, with slight friction, over a shoulder 9 on the journal 1, and
at its other extremity it is screw threaded to allow of the journal box being closed by
A lock nut 11 and counter nut 12 complete the arrangement.
means of a cap 10.

page_text: The building up of this journal box is effected in the following manner: The
sleeve 3 is first put in place on the journal, and then the rollers 8 are arranged in the
liner 6 (wherein they are retained, as I will explain further on) and are passed over
the sleeve 3.
The outer tube 7 is now put in position, then the rollers 8 are inserted in the
liner 5, and this latter is put in place, enclosing the rollers in the manner desired.
Lastly, the bushing or sleeve 2 is inserted, and is fixed in place by means of the
locknuts 11 and 12, the box being then tightly closed by screwing on the cap 10.
Any-suitable-arrangement-may be employed for keeping the rollers-S-in their
respective places relatively-to-each-other--and--for-keeping-their--axes-always-eon-
verging to the-same point.
By-way-of-example-l-will-now-deseribe Now my invention consists in the follow-
ing two arrangements (which have given very satisfactory results) for keeping the
rollers in their proper relative positions.
In the first, the rollers 8, which must not touch each other, are kept apart by small
intermediate rollers 13, arranged towards the part where the diameter of the rollers 8
is the largest. This arrangement is shewn more clearly in detail in Figs. 2 and 3.
Each roller 8 has an annular recess 14 (Fig. 1) wherein I arrange between every
two of the said rollers, a small roller 13, which is flanged or, in other words,, is also
provided with an annular recess 13*. The diameter of the flanges of these rollers is.
less than that of the rollers 8, but their intermediate part 15 is of larger diameter
than the intermediate portions 16 of the latter rollers.
To support the rollers 13, and to prevent them approaching, or receding from, the
journal 1, I arrange two conical rings, the exterior one 17, bearing on the flanges of
the rollers 13 (that is to say the parts having the largest diameter) whilst the interior
one 18, bears against the central portions 15.
At their other ends I maintain the rollers 8 in position simply by arranging a
slightly conical ring 19 in suitable small annular recesses or grooves 20. This ring is
merely for supporting the rollers 8 when the journal is withdrawn, and it is this
arrangement which enables the rollers, to be easily placed in the sleeves, as before
mentioned.
It is evident however that, in lieu of this ring, I might employ the arrangement of
intermediate rollers 13, above described. In fact, this has the advantage that I can
make these rollers from a tubular rod having a somewhat narrow axial bore (Fig. 4).
I then connect these rollers in pairs by means of a slender wire, whereby the placing
of the rollers in position is greatly facilitated. The ends of the wires are let into the
ends of the rollers, as indicated in dotted lines, Fig. 4, so as to prevent them rubbing
against the walls of the recesses 14.
Each of the bushings or liners 5 and 6, is provided at its wide end with a ring 30
which fits against the sleeves 2 and 3, thus constituting a tightly closed chamber 31
around the journal to receive the oil for lubricating.
As will be seen, this kind of journal box offers the following advantages:
1. Facility for regulating and taking up play, by tightening up the lock nuts 11
and 12.
2. Effectual means of closing, comprising the cap 10 and rings 30, whereby good
lubrication can be obtained with little oil.
The second arrangement, which I will describe by way of example, with reference
to Figs. 5 and 6, as being applied to an ordinary bearing with cylindrical rollers,
consists in interposing between the contact rollers 8, intermediate rollers 21, also
cylindrical and longer than the rollers 8. Said rollers 21 carry at their middle a collar or
ring 22 which projects and enters a groove 23 formed in the middle of the rollers 8.
The object of this arrangement is to prevent longitudinal slip of the rollers 21
relatively to the rollers 8. These latter are further provided with two other grooves 24
into which project ribs 25 formed on the bearing. In this manner any shifting of
the rollers parallel to the axle is obviated.
To keep the rollers 21 in place, I provide them with four grooves, two of which 26
are central with regard to the grooves 24 of the rollers 8, whilst the two others 27 are

page_text: at the extreme ends of the rollers 21. Rings 28 and 29 engaging these grooves
complete this arrangement and ensure thereto perfect rigidity, especially when the
journal is revolving rapidly.
I would-however-again-remark-that-the-arrangement-for-keeping-the-rollers-S-in
plaee-without-their-touching-each-other-may-be-of any suitable kind.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A journal box-or-bearing-having-taper--rollers-arranged in two-series each
having the axes of all its rollers-converging-to-a-common-point, the two-series
being symmetrically-arranged-towards each side of the bearing, substantially as
described.
2. A-journal box having two series of taper rollers;-eneh-series-being-arranged
between two suitable tapering bushings, and the whole being surrounded-by-A
tube-closed-nt one-end by a-shoulder-on the journal,-and-at-the-other-end-by a
serew-threaded cap;--substantially-as--described-with-reference-to Fig. 1-of the
drawings.
1. 3. A journal box having two series of taper rollers as under-Claim-2, wherein the
rollers 8 are kept in their proper relative positions by means of intermediate grooved
rollers 13 retained in place by rings 17 and 18, and also by means of rings 19 arranged
in grooves 20, substantially as described with reference to Figs. 1, 2 and 3 of the
drawings.
2. 4. The modification of the journal box referred to in Claim 1 3; in which the
rollers 8 are kept in position by two series of intermediate rollers 13 having an axial
bore and connected together by a wire, substantially as described with reference to
Fig. 4 of the drawings.
3. . The modification of the journal box referred to under Claim 3 1, in which
the rollers 8 are kept in position by intermediate rollers 21 provided at their middle
with a ring or collar 22, and at their ends with two grooves 26 and 27 to receive
rings 28 and 29, of which the former is inside the rollers 21, and the latter is outside,
them, substantially as described with reference to Figs. 5 and 6 of the drawings.
Dated this on day or April 1839.
