Improvements in Journals and in Journal‍ Boxes or Bearings.
1, JAMES FLETCHER MORELL, of 326 Market Street, Camden, New Jersey, United
States of America, Inventor 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 :-
My invention relates to anti-friction journals, journal boxes and bearings for cars
or other vehicles, embodying drums or rollers within the boxes and journals in contact
with the same, said journals being of such form, so as to roll upon said drums whose
peripheries are correspondingly shaped.
It also consists of the novel construction of the drums or rollers, as will be herein-
after fully set forth.
In the accompanying drawings
Figure 1 represents a partial side elevation and partial vertical section of anti-
friction journals, journal boxes and bearings embodying my invention.
Figure 2 represents a partial top view and partial horizontal section thereof, on
line x, x, Figure-1.-
Figure 3 represents a view of auxilliary friction rollers employed.
Figure 4 represents a section thereof, on line y, y.
:
Figure 5 represents a view of one of the hollow friction rollers employed.
Figure 6 represents a section thereof, on line z, z, Figure 5, Figures 3, 4, 5, and 6,
being on an enlarged scale.
Figure 7 represents a view of the journals, journal boxes and bearings on an
enlarged scale.
Figure 8 represents a view of the journal, on an enlarged scale.
Similar letters and numerals of reference indicate corresponding parts in the several
figures.
A designates the pedestal of a car, and B designates a box which is fitted within
said pedestal and capable of vertical motions therein.
Mounted within the box on axles 1 are friction cylinders or rollers 2 which are
placed side by side and rested upon the journal C, of the car axle, said journal being
of the form of the frustum of a circular spindle, as shown in Figures 2 and 8, and
said cylinders having their peripheries concave, so as to conform to the shape of the
journal C. The axles 1 are connected with the box B, as will be most clearly shown
in Figure 2. The drums are hollow, and contain a series of rollers 3, which are
arranged around the axle 1, and mounted upon heads 4, the latter being provided
with radial slots 5, to receive the journal of said rollers 3, it being noticed that
said rollers 3 are in contact with the inner peripheries of the rims of the cylinders or
rollers 2.
When the car is in motion, the rollers 2, rotate in contact with the journal C, and
the rollers 3, which are interposed between the rim of said rollers 2, and the axle 1,
revolve in contact with said rollers 2, and axle 1, whereby the journal rotates with
reduced friction on its bearings which are the rollers 2, as has been stated, it being
seen that the rollers 2, which are hollow or formed of rims as set forth, are
strengthened or braced and sustained by the rollers 3, whereby crushing or breaking
of said rollers 2, is prevented.
Owing to the construction of the journal of the form of the frustum of a circular
pindle and the concave peripheries of the rollers 2, said journals are permitted to
oll on their bearings thus relieving the journals of strain during the oscillation of
waying of the car, and preventing binding of the journal with its bearings.
The engagement of the peripheries of the rollers 2, with the journal C, also serve to
etain said rollers in position avoiding the contact of the latter with the box, and
onsequent friction therewith.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
First. A journal of the form of a frustum, of a circular spindle and a roller or
bearing for the same, having a concave periphery to receive, said journal, combined
and operating substantially as described.
Second. A hollow friction roller for a journal or axle, containing a circle of friction
rollers and having a concave periphery, in combination with a journal of the
form of a frustum, of a circular spindle occupying said concave periphery, substantially
as described.
Third. The combination of the journal C with the hollow rollers 2, the axles 1,
within said hollow rollers, and anti-friction rollers within said hollow rollers and
bearing on the inner face of said rollers 2, and on the axles 1, substantially as and
for the purpose set forth.
Fourth. A hollow friction roller for a journal or axle, containing friction rollers 3,
and the slotted heads 4, supporting said rollers 3, substantially as described.
