between Journal-bearings and Adjacent Pulleys or the like.
1, ELWIN RUFUS HYDE, of Springfield, Massachusetts United States of America,
Manufacturer, do hereby declare the nature of my invention for "IMPROVEMENTS
RELATING TO DEVICES FOR TAKING UP THE END-WEAR BETWEEN JOURNAL-BEARINGS
AND ADJACENT PULLEYS OR THE LIKE" 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 improvements in devices for taking up the wear between
the end of journal bearings and the ends or hubs of a pulley or pulleys, or other
wheel, on a shaft or arbor supported in said bearings, whereby endwise movement of
said pulley or wheel, or of the shaft to which the same is secured, will be prevented,
and it consists in the construction and combination of parts, all substantially as will
hereinafter more fully appear.
In the accompanying drawings the present invention is illustrated as employed in
connection with a knife grinding machine, the figure being a partial elevation and. a
longitudinal vertical section thereof.
In the drawings A. A. represent standards carrying the journal boxes B. B. in
which bears the arbor or shaft C, having thereon between said journal boxes the
hubbed speed-wheel D, and, at each end, carrying an emery or other suitable grinding
wheel G, as shown.
Between said journal bearings B B and the end of the hub a, of the pulley are
interposed loose collars b, b. Headed screws ff are entered longitudinally into screw-
thread sockets in the end of the hub of the pulley and in a manner to be turned
outwardly therefrom to bear against the said collars b, b, to force them outwardly
and maintain them against the ends of the said journal bearings.
On the wearing away of the end of the screws, the journal bearings, or the
collars, to such an extent that the arbor would have any endwise play in its bearings
the said screws are turned outwardly to force the collars b. b. closely against the journal
bearings.

page_text: The ends of each of the journal boxes B. B. are preferably provided with annular
ribs or flanges g, g, and the collars b, b, as also the collars 12 62 outside of and
between said journal bearings and the grinding wheels, have, within their ends,
recesses or depressions m. m. surrounded by the annular walls n, which annular walls
overlie the said annular flanges of the jourral bearings, thereby preventing the
entrance of dirt, etc., into the said bearings.
Upon the periphery of collars 6122, in the plane of the walls n, are formed
annular flanges o which are conical in cross-section as shown, whereby any portion of
the oil used to lubricate the journal-boxes B B which may work out at the ends of
said boxes will be caused to ascend the inclined sides of said flanges and will be
expelled centrifugally, thereby keeping the surface of the grinding wheels. G and
pulley D entirely free from oil.
Said projecting annular walls and flanges thus form valuable and important
auxiliaries to the wear compensating devices, in that they fully protect the journal
boxes from dirt and other foreign matter, and provide for a speedy expulsion of
surplus oil.
It is obvious that the screws could enter tapped holes in the collars bb and
have their heads bear against the hub of wheel D instead of being arranged as
shown, but as the wheel hub affords a more substantial bearing for said screws and
admits of the use of a larger screw, I prefer the arrangement first described.
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. The combination with an arbor mounted to revolve within suitable journal-
boxes and a pulley or other wheel mounted upon said arbor between said boxes, of
collars mounted upon said arbor hetween the hub of said wheel and said boxes, and
two or more screws entering tapped holes either in said collars or in the wheel hub,
parallel with the arbor, said screws at their outer ends bearing against the adjacent
end of the wheel hub or collar, as the case may be, whereby an outward movement
of said screws will compensate for the wear of said parts in the direction of the length
of the arbor, substantially as described.
2. The combination with the journal bearings B B of an arbor having the pulley
provided with the screws and the loose collars b. b. between said screws and journal
bearings, substantially as described.
3. In a grinding machine, the combination, with the journal bearings B. B
having on their ends the annular flanges g. of the arbor having thereon between
said bearings the pulley provided with the screws f, the loose collars between
said screws and the inner ends of said journal bearings, the grinding wheels on the
end of portions of said arbor, and the collars between said grinding wheels and
the outer end of said journal bearings, the said collars 2 being provided
with the depressions m, all substantially as and for the purpose described.
4. The combination with the journal-boxes B B, arbor C and wheels D G G
mounted upon said arbor, of collars also mounted upon said arbor and over-
lapping at one end a portion of said journal-boxes, said collars having, adjacent to said
ends, the peripheral flanges o the sides of which are inclined substantially as shown
and for the purpose set forth.
Dated this 28th day of November 1888.
