Improvements in Journal Boxes.
I, WILLIAM WARREN WAINWRIGHT, of Connersville, Fayette County,
Indiana, United States of America, Engineer, 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 pertains to improvements in journal boxes designed for adjustment
both for the purpose of closing up the box upon the shaft as the shaft and box
wear loose and for centering the shaft in the housing or hanger or pedestal or
bracket or whatever fixed support the box may be mounted in. My improvements
will be readily understood from the following description taken in connection with
the accompanying drawing in which :-
Fig. 1, is an end view of a journal box exemplifying my invention :
Fig. 2, a vertical longitudinal section thereof;
Fig. 3, a side elevation of the bearing-sleeve:
Fig. 4, an end view of the bearing-sleeve: and
Fig. 5 an end view of the adjusting-sleeve.
Figs. 1, 4 and 5 are end views at the left hand end of Figs. 2 and 3.
In the drawings:
:-
A, indicates the housing, hanger, bracket, pedestal or such other fixed support
as is to carry the journal box, this housing having a cylindrical bore in the axial
line of the intended box, such bore being considerably larger than the shaft when
it is run in the box :
B, the shaft:
C, the bearing-sleeve, bored to fit accurately upon the shaft within the bore of
the housing:
D, a longitudinal cut entirely through the bearing-sleeve to permit of the sleeve
closing up upon the shaft as the shaft and sleeve wear away:
E, other longitudinal cuts in the bearing-sleeve but not extending to the bore
of the sleeve, the object of these cuts E being to weaken the sleeve so that it may
more readily be closed inwardly upon the shaft, these cuts not being needed in
case the bearing-sleeve is so thin as to permit proper inward springing:
F, lugs upon the exterior of the bearing-sleeve extending outwardly beyond
the bore in the housing and seating against the face of the housing and serving to
prevent the bearing-sleeve going end wise into the bore of the housing beyond the
proper distance :
G, circumferential grooves turned in the exterior of the bearing-sleeve and
having sloping peripheries, producing upon the bearing-sleeve a series of ribs
having ratchet-shaped cross-sections, these ribs enlarging in the direction away
from the lugs F:

housing, the bore of this adjusting-sleeve being grooved to fit the ribs upon the
bearing-sleeve:
I, a series of longitudinal cuts extending entirely through the adjusting-sleeve
and dividing the adjusting-sleeve into a series of segmental sections, three in the
example :
J, a lug projecting outwardly from each of the segmental sections of the
adjusting-sleeve at one end of the sleeve, at the end corresponding with the lugs F
upon the bearing sleeve, the adjusting-sleeve projecting at that end outwardly from
the bore in the housing so that there is an adjusting distance left between the
inner faces of these lugs and the near face of the housing:
K, a screw, one for each of the segmental sections of the adjusting-sleeve,
engaging the lug J and the housing and serving as a means by which the segmental
sections of the adjusting-sleeve may be pushed forcibly further into the bore of
the housing, the end of the adjusting-sleeve furthest from the lugs J preferably
setting back from the corresponding face of the housing to permit of end wise
adjustment of the adjusting-sleeve without protruding the right-hand end of the
adjusting-sleeve beyond the face of the housing:
L, the ratchet-shaped ribs in the bore of the adjusting-sleeve intermembering
with the ribs upon the bearing-sleeve:
M, (Fig. 5) notches or gaps in the end of the adjusting-sleeve, between the
lugs J, to permit the lugs F of the bearing-sleeve to take a bearing against the
face of the housing: and
N, the gaps between the lugs F of the bearing-sleeve to permit of the presence
of the lugs J of the adjusting-sleeve.
Viewing the device as seen in Fig. 2, all the parts are to be assumed as in good
order, the bearing-sleeve fitting the shaft and the shaft being concentric with the
bore in the housing. As the shaft and bearing-sleeve wear, thus loosening the
fit of the journal, the screws K may be turned thus urging the adjusting-sleeve
inwardly, the inclined ribs of the adjusting-sleeve compressing the bearing-sleeve
radially and closing the bearing-sleeve inwardly upon the shaft. Should the
greatest amount of wear have taken place in the lower portion of the box, as
would be the case where the shaft supported considerable weight, a superior degree
of adjustment may be given to the lower section of the adjusting-sleeve thus
restoring the shaft to its concentric position with reference to the bore of the
housing. Similarly the several sections of the adjusting-sleeve may be indepen-
dently adjusted to compensate for greater wear in any particular direction and thus
bring the shaft to concentric position. Screws K may be removed thus slackening
the fit of the parts and permitting the entire box to be withdrawn endwise from
the bore of the housing.
This journal-box will be found of special utility in connection with rotary
blowers the shafts of whose pistons require to be maintained accurately in position
concentric with the bore of the cylinders, and in which also such adjustments as
are to be made must be made at one end of the journal-box, the other end of the
journal-box being inaccessible.
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 :-
1. In a journal box, the combination, substantially as set forth, of a support
having a cylindrical bore, a bearing-sleeve disposed therein and having a longitudinal
cut and provided with circumferential ribs having ratchet-shaped cross-sections,
means for preventing endwise motion of said bearing-sleeve in said bore in one
direction, an adjusting-sleeve formed in segmental sections and having a bore grooved
to fit the ribs of the bearing-sleeve and having its exterior fitting the bore of said
support, and means for adjusting the sections of said adjusting-sleeve endwise
ndependently in the bore of said support.

page_text: 2. In a journal-box, the combination, substantially as set forth, of a support
having a cylindrical bore, a bearing-sleeve therein provided with a longitudinal cut
and with exterior circumferential ratchet-shaped ribs and with a lug or lugs engaging
the face of said support, a longitudinally cut adjusting-sleeve fitting the bore of said
support and having a bore to intermember with the ribs of the bearing-sleeve, and
a screw or screws engaging said adjusting-sleeve and support, and serving to push
the sleeve end wise in the bore of the support.
3. In a journal box, the combination, substantially as set forth, of a support
having a cylindrical bore, a bearing-sleeve therein having a longitudinal cut and
having circumferential ratchet-shaped ribs and having near one end lugs engaging
the face of said support, an adjusting-sleeve formed in segmental sections and fitting
the bore of said support and having a bore intermembering with said ratchet-shaped
ribs and having lugs projecting outwardly at one end, and adjusting-screws engaging
said support and the lugs of said adjusting-sleeve and serving to adjust the sections
of the adjusting-sleeve end wise with reference to said bearing-sleeve.
