Improvements in and relating to Shaft and Journal Bearings.
I, AMOS CLINTON STILSON, a Citizen of the United States of America,
residing at No. 17 Washington Street, in the Town of Kendall Creek, County of
McKean, and State of Pennsylvania, one of the United States of America,
Gentleman, 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 that class of shaft and journal bearings which have
rollers provided with cogs or teeth gearing with teeth or cogs upon the journal
box. The object of the invention is to improve upon the general construction of
this class of device, and to that end the nature of the invention consists of con-
structions and combinations, ail as will hereinafter be described in the Specification
and pointed out in the claims, reference being had to the accompanying drawings,
in which-
Figure 1 represents an end elevation of the box, two of the collars being removed,
and the shaft being in section.
Figure 2 a section of the box proper and the rollers and shaft in elevation.
A, represents a box which may be made in any desired way and provided with
the annular recess, a, and cogs or teeth, a', at each end. In the recess, «, are placed
rollers, A', of substantially the same length as the width of the recess, a, so that
the ends, a², of the roller abat against the shoulders, a³, that form the side walls of
said recess. The journals of the rollers are the reduced parts, at, which fit snugly
against the bearing faces, a, on the box proper and hold the rollers, A', snug
against the shaft or journal, A². The outer ends of each of the rollers are provided
with the same number of cogs or teeth, a, that engage with the teeth, a', on the
box, A, and with the teeth, a', of the separate adjusting rings or intermediate
gears, A³, encircling the shaft or journal, A. Upon the ends of the cogs, a³, of
journals, a', are collars,, of substantially the same diameter as the journals. These
collars, together with the journals form walls or stops, which serve to keep the
rings, A³, in place. These rings, A³, have a central opening of larger diameter
than the shaft from which they are held from contact by reason of their contact
with the cogs or teeth, «°. In short, the rollers support the shafting and the rings
guide the rollers. It is obvious that these bearings can be used for shafting, axles,
or any device requiring anti-friction rollers.
The operation of the device is as follows: The shaft or journal is revolved in
the usual way and by reason of the contact of its periphery with the periphery
of the rollers the latter are revolved. As these rollers are geared to the box and
intermediate rings they move around the box as the shaft or journal turns. The
gear or teeth on the box guide the movements of the rollers and the rings adjust.
the latter so that they will always be an equal distance from cach other and thus
form a firm support for the shaft or journal with the least possible friction.
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:
In a journal bearing, the combination of a box having a recess and teeth arranged
internally in the ends of the box, rollers fitting in said recesses and having reduced
journals provided with teeth at each end, and the rings, A', provided with a central
opening of larger diameter than the shaft, said rings having teeth which mesh with

page_text: the teeth upon the ends of the rollers whereby said rings are held from contact
with the shaft, substantially as set forth.
