I, BENJAMIN SMITH LAWSON, of Red Bank, in the County of Monmouth, and
State of New Jersey, 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 improvements in journal-boxes, and the object is to
simplify and improve the construction, and thereby increase the efficiency and
durability of the device. To these ends the invention consists in the construction,
combination and arrangement of the several elements of the device, as will be
hereinafter more fully described and particularly pointed out in the claims.
In the accompanying drawings the same reference characters indicate the same
parts of the invention.
Fig. 1 is a longitudinal section of a journal box embodying my invention.
Fig. 2 is a vertical section on the line 2-2 of Fig. 1, looking in the direction
of the arrow.
Fig. 3 is a perspective view of the yoke.
Fig.
Fig. 5 is a section on line - of Fig. 2.
is a similar view of the yoke-box.
A denotes the journal box provided with the removable bonnet a³ which in
turn is provided with the usual hinged door to permit access to the box for
inspection or lubricating purposes: The bottom of the journal box is formed with
a lubricant chamber a in which a suitable absorbent packing a³ is placed to
retain the lubricant.
B denotes the axle-journal, the outer end of which is formed with an annular
groove b, and b, denotes a dust guard fixed to the inner end of the journal, so
as to encompass and close the contiguous open end of the journal box and prevent
the entrance of foreign matter to the bearing.
B denotes a bearing sleeve which encompasses the journal B, and it is formed
at each end with a collar b³.
F, F, denote annular grooves formed externally on the sleeve to receive the
split spring rings E, E.
C, C, denote cylindrical rollers, arranged parallel with each other, and forming
a continuous annular series, encompassing the sleeve and spring rings, the tension
of the latter being exerted radially outward to retain the rollers in contact with
the concentric bearing face a, forming the inner wall of the box A.
1) represents a yoke, the horizontal arms of which are arranged to be seated
in correspondingly shaped recesses formed in the inner face of the bonnet, so as
to secure the yoke in place when the bonnet is secured on the box, and to permit
the removal of the yoke when the bonnet is detached.
The central portion of the yoke is preferably arch-shaped to receive the yoke-
box which in turn snugly fits the groove 64 in the outer end of the journal.
The inner parallel walls d', d of the yoke D, engage the corresponding
parallel outer walls of the yoke-box & to prevent the latter rotating in the yoke.
The upper portion of the yoke-box is formed with parallel radial flanges d'

page_text: and which snugly encompass the parallel faces of the yoke, and likewise snugly
fit the parallel walls of the journal-groove 6, the flanges & preventing any
inward longitudinal or end movement of the journal, and the flanges d' prevent-
ing any outward end movement of the same, and this latter flange of the
box din addition to forming an end bearing in one direction for the journal,
also extends across the face of the outer end of the sleeve B which as shown in
Fig. 1, is aligned with the inner wall of the journal groove 4, thus serving the
double purpose of preventing any outward end movement of the sleeve or journal,
while any movement of the sleeve on the journal in the opposite direction is
prevented by the dust guard b.
In the accompanying drawings I have shown the invention in the best form
now known to me, but various modifications may be employed without departing
from the spirit of the invention as set forth in the claims.
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. The combination of an axle or shaft formed with an annular groove, a
fastening member composed of a main body having the intermediate portion of
its lower face provided with shoulders, aligned with opposite sides of the groove
in the axle or shaft, and a detachable engaging piece inserted into said groove
and formed with shoulders interposed between the former shoulders and the
adjacent surfaces of the axle or shaft, and a casing having a movable bonnet or
closure for holding the fastening member in its adjusted position, said bonnet or
closure being provided with a socket for receiving a portion of the main body
of the fastening member, substantially as and for the purpose described.
2. The combination of an axle or shaft formed with an annular groove, a
fastening member composed of a main body having the intermediate portion of
its lower face provided with the shoulders aligned with opposite sides of tho
groove in the axle or shaft, and a detachable engaging piece inserted into said
groove and formed with shoulders engaged with opposite sides of the main body,
and additional shoulders interposed between the shoulders on the intermediate
portion of the lower face of said main body and the adjacent surfaces of the axle
or shaft, and a casing having a movable bonnet or closure for holding the fasten-
ing member in its adjusted position, said bonnet or closure being provided with
sockets for receiving the ends of the main body of the fastening member, sub-
stantially as and for the purpose specified.
3. The combination of an axle or shaft, a sleeve on the axle or shaft, a fasten-
ing member having its intermediate portion engaged with the sleeve for pre-
venting endwise movement thereof, and a casing having a movable bonnet or
closure holding the fastening member in position, said bonnet or closure having
its inner face provided with sockets for receiving the ends of the fastening
member, substantially as and for the purpose described.
4. The combination of an axle or shaft formed with an annular groove; a sleeve
on the axle or shaft at one side of the groove, a casing, and a fastening member
supported by the casing and provided with an engaging piece inserted into the
groove and having one of its sides engaging with one wall of the groove and with
the sleeve, substantially as and for the purpose described.
