A communication from WILLIAM SAMUEL SHARPNECKS, of Denver, Arapahoe County,
Colorado, United States of America.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
Engineer, M.I.M.E., Fel. Inst. P.A., 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 :-
This improvement relates more particularly to that class of anti-friction journal
boxes wherein a series of rollers revolve around the shaft and are held in a regular
position as respects each other around said shaft; and the invention consists in the
peculiar construction, combination and arrangement of parts hereinafter more
particularly described.
To more easily describe the invention reference is made to the accompanying
drawings in which Fig. 1 is a vertical, central longitudinal section of a journal box for
railroad cars constructed according to this improvement and Fig. 2 is an irregular
transverse vertical section.
In said drawings A represents the axle or shaft provided with a projecting rim a
near the centre of the journal around which are arranged several hollow rollers B
preferably six, but this may be varied by changing the relative sizes of the rollers and
journals. Each of these rollers is provided with an annular groove b fitting the rim a
in the journal and also fitting rib c in the bearing C.
At the opposite ends of the series of rings are separating washers D, (one half of one
of the washers only being shown in Fig. 2) which washers are connected together by
a series of pins E, each of which pins passes through a roller and all of them enter and
pass through the separating washers D and are secured by nuts G, so as to form a
kind of cage surrounding the journal A, and on the bars of which cage the rollers B
turn.
It will be seen on examining Fig. 2 that the pins E are considerably smaller than
the bore of the rollers B which leaves room for a set of smaller rollers H which nicely
fit the space between the pins and the inner circumference of the large rollers, the
object of which is to keep said larger rollers B in their proper position around the
pins E and to prevent friction between the rollers B and pins E.

page_text: By this construction a journal box is formed in which all the bearing rollers are
kept in their proper positions so that they cannot rub against each other, and said
bearing rollers are relieved from friction against the pins which keep them in place,
whereby they revolve with comparatively little or no friction and will run a long time
without oil and without "cutting."
The parts so far described may be used with any appropriate casing or boxing but
the arrangement shown in the drawing is preferred, and which may be described as
follows: The box consists of two parts, the main shell I and the cap I', the latter
being hinged to the former at the upper corner i and secured below by bolts J and
nuts j.
To the cap I¹ is secured a disk Ķ having a deep groove k in which is set a ball L,
that preferably bears against a hardened steel plate secured to the end of the axle, but
may bear against the end of the axle if preferred, in which case the end of the axle
should be case hardened. This disk K is held in place by a stud M and nuts N, and by
placing "liners" between said disk and the cap f any adjustment desired may be had,
or any wear taken up should any be found to occur.
To
The box rests on a roller O that in its turn rests in a recess c¹ made for it in the top
of the bearing C. In the top of the box is made a corresponding recess i¹ so that the
roller is prevented from moving sidewise although free to roll to a limited extent.
prevent any accidental displacement of the roller ribs or projections may be provided
on each side of the recess c as shown by dotted lines.
To strengthen the bearing, the same is provided with ribs cle" which connects the
concave part of the bearing with its flat top and extends above the latter as shown in
Fig. 1.
From this description and the accompanying drawing it will be seen that not only
is the rolling friction reduced to a minimum but that the friction due to end thrust is
materially lessened, if not altogether eliminated by the ball L and disk K while the
bearing and journal will move end wise easily and smoothly in the box or casing.
Having now particularly described and ascertained the nature of my said invention
as communicated to me by my foreign correspondent and in what manner the same is
to be performed, I declare that what I claim is :
1 The combination in a journal box, of a series of hollow rollers B, the separating
washers D, the pins E, passing through the rollers B, into the washers D and a series
of smaller rollers H between the rollers B and the pins on which they revolve, sub-
stantially as described.
2-The combination in a journal box, of a journal A, having a rim a, a series of
hollow rollers B having grooves to fit the rim, separating washers D at each end, a
series of pins E passing through said rollers B and having their end secured in the
washers, and a series of small rollers enclosed in each large roller, substantially as
described.
3-The combination in a journal box, of the box I, cap I' with the ball L, disk K
having groove k and an adjusting device as the stud M and nut N, substantially as
described.
4 The combination with a journal of the casting I, cap I', disk K, hall L, roller O,
bearing C, hollow rollers B, pins E, washer Dand small rollers H, intermediate of the
pins E and hollow rollers B, substantially as described. .
