1, WILLIAM HAMILTON WRIGHT, Manufacturer, of Bridgeburg, Ontario,
Dominion of Canada, do hereby declare the nature of this invention to be as
follows:-
This invention relates to roller bearings.
According to the present invention a bearing comprising taper rollers in cir-
cular series, with the smaller ends of the rollers in one series presented towards
the smaller ends of the rollers in other series, is so constructed that the hub
or sleeve encircling a shouldered shaft can be removed from the latter or
moved endwise along it without disturbance or adjustment of the rollers; to
render this possible the sleeve is so constructed that the rollers will come
away with it and the shaft forming a part of the bearing is provided with taper
bearing-surfaces upon which the rollers run; these surfaces (one of which forms
the shouldered portion aforesaid) converge one towards the other, and one of
them is removable, being constituted by the exterior of a ring screwed upon,
or otherwise adjustably secured to, the shaft. The sleeve is preferably tapered
upon its interior, and the tapered rollers are secured upon that
interior, the smaller ends of the coned surfaces in the sleeve being pre-
sented towards the centre of the bearing in such a manner that the latter as a
whole has its smallest diameter intermediate of its length so as to be able to
take up
end thrust as well as thrust which is transverse to the axis of the bearing.
To retain the tapered rollers upon the interior of the sleeve the latter may
be provided with adjustable removable rings, flanged to overlap the ends of
the spindles of the rollers so as to retain them when the sleeve is removed from
its normal position, and being provided with shoulders or abutments for the
outer end faces of the rollers to bear against; these rings may be screwed
into portions of the sleeve which are threaded to receive them, and can be
locked by screw-pins. The rings to retain the rollers may be otherwise secured
than by screw threads.
The sleeve is provided with a cap which closes up an annular space between
it and the adjacent surface of the shaft in proximity to the larger portion of
the shaft beyond the shoulder; upon the interior of this cap, which is prefer-
ably screwed into place, there is space to receive a packing of felt which is
kept within the cavity in the cover by means of a flat washer cut through
radially and sprung into a groove in the cap after the felt has been put in
position.
A bearing thus constructed possesses the characteristic advantage that the
sleeve can be removed in one direction along the shaft (for instance as in the
removal of a wheel from its axle) without the need for disturbing any part of it
after the ring carrying the outer of the two bearing cones is removed from the
shaft; in this way the whole of the bearing rollers, and the other details of

page_text: the bearing, except the outer cone and the nuts and washers which secure it to
the shaft, come away readily with the wheel; thus the latter can be readily
taken off or put into place again with the minimum of trouble and without
risk of the loss of any of its parts.

Improvements in or relating to Roller Bearings.
I, WILLIAM HAMILTON WRIGHT, Manufacturer, of Bridgeburg, Ontario,
Dominion of Canada, 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 invention relates to roller bearings.
According to the present invention a bearing comprising taper rollers in cir-
cular series, with the smaller ends of the rollers in one series presented towards
the smaller ends of the rollers in other series, is so constructed that the hub
or sleeve encircling a shouldered shaft can be removed from the latter or
moved endwise along it without disturbance or adjustment of the rollers; to
render this possible the sleeve is so constructed that the rollers will come
away with it and the shaft forming a part of the bearing is provided with taper
bearing-surfaces upon which the rollers run; these surfaces (one of which forms
the shouldered portion aforesaid) converge one towards the other, and one of
them is removable, being constituted by the exterior of a ring screwed upon,
or otherwise adjustably secured to the shaft. The sleeve is preferably tapered
upon its interior, and the tapered rollers are secured upon that
interior, the smaller ends of the coned surfaces in the sleeve being pre-
sented towards the centre of the bearing in such a manner that the latter as a
whole has its smallest diameter intermediate of its length so as to be able to
take up end thrust as well as thrust which is transverse to the axis of the bearings.
To retain the tapered rollers upon the interior of the sleeve the latter may
be provided with adjustable removable rings, flanged to overlap the ends of
the spindles of the rollers so as to retain them when the sleeve is removed from
its normal position, and being provided with shoulders or abutments for the
outer end faces of the rollers to bear against; these rings may be screwed
into portions of the sleeve which are threaded to receive them, and can be
locked by screw-pins. The rings to retain the rollers may be otherwise secured
by screw threads.
The sleeve is provided with a cap which closes up an annular space between
it and the adjacent surface of the shaft in proximity to the larger portion of
the shaft beyond the shoulder; upon the interior of this cap, which is prefer-
ably screwed into place, there is place to receive a packing of felt which is
kept within the cavity in the cover by means of a flat washer cut through
radially and sprung into a groove in the cap after the felt has been put in
position.
A bearing thus constructed possesses the characteristic advantage that the
sleeve can be removed in one direction along the shaft (for instance as in the
removal of a wheel from its axis) without the need for disturbing the adjustment
of the bearing the ring carrying the outer of the two bearing cones being
removed from the shaft; in this way the whole of the bearing rollers, and the

page_text: other details of the bearing, except the outer cone and the nuts and washers.
which secure it to the shaft, come away readily with the wheel; thus the
latter can be readily taken off or put into place again with the minimum of
trouble and without risk of the loss of any of its parts.
In the accompanying drawings which illustrate one construction of roller bear-
ing according to this invention
Figure 1 is a longitudinal central section through the bearing;
Figure 2 is a transverse section on the line 2-2 of Figure 1, and
Figure 3 is a view of one of the details.
Figure 4 is a similar view to Figure 1 showing an alternative method of secur-
ing the removable cone.
Like letters indicate like parts throughout the drawings.
A is an axle or shaft having a cone formed upon it at A¹ and fitted with
an adjustable and removable cone A2 which fits snugly on to the free end of the
axle which is preferably slightly reduced in diameter as shown at A³. Beyond this
portion A³ the axle is further reduced in diameter at A and this portion is pro-
vided with a screw thread.
Encircling the axle A is a sleeve B made, for convenience in two parts which
are screwed into a ring B¹ and secured as by screws C to a hub D.
The sleeve B is tapered outwardly at each end so that the portions of its interior
which are opposite to the cones A¹ and A3 forms, with those cones, bearings or
races for tapered rollers E. These rollers E are arranged in two circular series,
the smaller ends of the rollers in one series being presented towards the smaller
ends of those in the other series. The tapered rollers E are retained upon the
interior of the sleeve B by means of adjustable removable rings F which are
screwed to engage with threaded portions of the sleeve B and are retained in
their position by screws F¹. The rings F are flanged as at F2 so as to overlap the
ends of the spindles E¹ of the rollers and thus retain the latter in their places
when the sleeve is removed from the axle A. The rings F in proximity to the
outer ends of the rollers C are provided with shoulders or abutments at F3 which
assist in retaining the rollers but are not intended to come in contact with them
when the bearing is working normally.
A nut A screws into the interior of the cone A2 and affords means whereby the
position of the latter on the part A³ of the axle A, may be adjusted. A similar
nut A6 acts as a lock nut and a washer A having a feather engaging with a
slot A8 in the cone A³, prevents the nut A5 rotating when the lock nut A6 is
tightened.
A slot A¹³ may be provided in the portion A³ of the axle, the cone A² placed
on the axle so that this slot corresponds with the slot A8 above described, and a
key A placed in these slots to prevent turning of the cone on the axle.
The cone A is kept securely in position upon the axle A by means
of a nut A10, which is screwed on to the portion A of the axle, and is kept from
slackening by the key A" secured in a key way A"
A cap G completely closes the outer end of the hub by screwing into the end of
the sleeve B, and the space between the inner end of the hub and the axle A
is closed by another screwed cap H. The cap H is provided with an annular
groove H in its interior and a divided ring or washer J is sprung into this
groove and serves to keep a packing of felt K in place. The felt is pressed closely
against the axle A by the action of a spring K' surrounding it. Sometimes
the felt K and the divided ring J are dispensed with, and a packing of leather is
secured inside the cap say by screws.
It will be seen that after unscrewing the cap G and removing the cone A2,
the sleeve B can be moved along the axle, and if necessary completely removed
from the latter, carrying the rollers E with it, thus if the bearing forms part of a
wheel the whole wheel can be readily taken off or put into place again with the
minimum amount of trouble and without risk of the loss of any of its parts.
An alternative method of securing the cone A2 on to the axle is shown in
Figure 4.

page_text: In this case the portion A³ of the axle is provided with a right hand screw
thread, and the cone A³ is provided with a thread to engage the same.
The portion A is preferably provided with a left hand thread, and a washer A
is provided between the cone and the locknut A10. The keys A¹ and A" are
dispensed with.
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
1. In a-roller-bearing securing the-tapered-rollers-upon-the-interior-of-a-sleeve-so
that-when-the-latter-is-removed the-rollers-come-away with it.
2. In a roller bearing-the-combination-with-a shaft-having-tapered-bearing-sur-
faces upon it-of-a-sleeve-movable-along the shaft without disturbance-or-adjustment
of-tapered rollers-secured to the-interior-of-the sleeve.
3. In a roller bearing the combination-with-a-sleeve-internally tapered of-tapered
rollers-secured-upon-its-interior-and-an-axle-carrying a cone which-is-removable-for
the-purpose-described.

interior--is--combined--with-a-shaft--having-fixed-and-removable-cones in-such--a
manner-that-the-sleeve-ean-be-moved-along-the-shaft without disturbance-or-adjust-

1. . In a roller bearing the combination with a sleeve of adjustable removable
rings upon its interior serving as retainers for the rollers substantially as
described.
