Improvements in or connected with Spindles and Bearings of
Machinery.
I, CHARLES MERRY MCQUILKIN, of Denison, via Heyfield, Gippsland, in the
Colony of Victoria, Mechanic, do hereby declare the nature of this invention
to be as follows:-
The object of this invention is to provide what may be termed a false bearing"
for spindles, axles of wheels, shafting and the like machinery. In the use of my
invention the running of the shaft or the like will be more free, the false
bearing tending to reduce the friction. The invention is especially adapted for
the bearings of wheels or axles which revolve rapidly.
"
The invention consists of a sleeve of form to correspond with the recess of the
bearing block or standard which is to receive it, the said sleeve being in some
cases perforated to allow of a passage of lubricant through it.
The sleeve is set free within the recess of the bearing block or standard so as
to revolve, and the spindle, axle shaft or the like passes through same but is not
secured thereto. The revolving sleeve is preferably set to lie wholly within the
bearing block or standard and for this purpose the bearing recess of same will
have a shoulder on either side to keep it in position or at each end of sleeve a
ring will be set. These rings are preferably of circular section and are set free
from the shaft or axle. The rings may be slightly flattened on their inner
surfaces to prevent contact with shaft or axle and should fit the bearing block or
standard so as to revolve freely.
For the purposes above described the sleeves may be in the form of
1. A cylinder having perforations near its ends.
2. A cylinder having perforations at its centre.
3. A perforated cylinder having flanges at each end-in this case the sleeve
would not lie wholly within the block or standard but the flanges would form
stops outside of same.
4. A perforated cylinder having a flange at its centre. In this case the recess
of bearing block would require to be formed to receive such flange.
5. A tapered cylinder with or without a flange or flanges.
6. A cylinder having a central enlarged portion or bulb-this as in the other
cases being designed for a block having a corresponding recess.
Other modifications of above forms to suit particular bearings may be devised
without departing from the nature of my invention. The sleeves may be set to
lie wholly within blocks, as described, or may extend just without the fixed bear-
ing, the shaft or axle in all cases resting solely upon the revolving sleeve.
In some cases where the sleeves receive the end of a shaft one end of sleeve may
be closed.
The sleeve will be constructed of various diameters to suit their particular
application to different machinery.

forations may be dispensed with if required.

Improvements in or connected with Spindles and Bearings of
Machinery.
I, CHARLES MERRY MCQUILKIN, of Denison, via Heyfield, Gippsland, in the
Colony of Victoria, Mechanic, 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:-

false
The object of this invention is to provide what may be termed a "false bearing"
for spindies, axles of wheels, shaiting, and the like machinery. In the use of my
invention the running of the shatt or the like will be more free, the
bearing" tending to reduce the friction. The invention is especially adapted for
the bearings of wheels or axles which revolve rapidly.
The invention consists in employing a sleeve encircling the spindle and lying
within the bearing block or standard, the said sleeve being in some cases per-
forated to allow of a passage of lubricant through it and from one side of sleeve
to the other. The sleeve is set free within the recess of the bearing block or
standard so as to revolve, and the spindle, axle, shaft or the like passes through
same but is not secured thereto.
In order to make the invention clear I will now refer to the accompanying
sheet of drawings in which----
Figures 1, 2 and 3 represent longitudinal vertical sections through bearing
blocks shewing rotating sleeves-of modified forms-in position encircling
spindles.
Figures 4 to 15b shew modified forms of sleeves-detached-that may be
employed.
For the purposes above described the sleeves may be in the form of
1. A cylinder having perforations near its ends.
2. A cylinder having perforations at its centre.
3. A perforated cylinder having flanges at each end.
4. A perforated cylinder having a flange at its centre.
5. A tapered cylinder with or without a flange or flanges.
6. A cylinder having a central enlarged portion or bulb.
The above forms may be perforated or plain as may be desired and other modi-
fications of the above forms to suit particular bearings may be devised without
departing from the nature of my invention.
Referring to Figure 1 "A" represents the sleeve, "B" the bearing block or
standard and "C" the spindle, shaft or axle. The revolving sleeve is preferably
-as here shewn--set to lie wholly within the bearing block or standard and for
this purpose the bearing recess of same will have shoulders b on either side to
keep it in position. This sleeve "A" is preferably provided with perforations a
near each end as shown in Figures 1 and 6 or it might be perforated at centre as
shewn in Figure 7 or perforated throughout its length as shewn in Figure 5 or

page_text: the sleeve might in some cases be made without perforations as shewn in Figure 4,
the latter is adapted for a short bearing.
Referring to Figure 2 the sleeve
"
A is here shewn with flanges a¹ at its
ends (see also Figure 8) which lie outside the bearing block "B
stops to keep it in position during its rotation. In this figure the sleeve is
so forming
represented as being perforated throughout its length, but it will be understood
that they may be confined to portions of the length.
Referring to Figure 3 the sleeve A2" is provided with a central rim
flange a² (see also Figure 9) and the bearing block "B" is recessed out to receive
the said rim which has the same effect as the flanges a¹ (Figure 2) or the
shoulders 6 (Figure 1).
"
"
or
The bearing blocks are provided with the usual oil passages
have cups d leading to the sleeves. These passages are preferably arranged to
D" which may
conduct the oil directly to the perforations in the sleeves.
In Figure 10 I have shewn a tapered sleeve "A" with a flange a" at its larger
end and in Figure 11 a cylindrical sleeve
These forms would be suited to vertical bearings.
A4" with a flange a at one end.
In Figures 12 and 12" I have shewn a cylindrical sleeve "A" having a central
enlarged portion or bulb and in Figure 13 a tapered sleeve
bulb and in Figures 14 and 14" the sleeve
A6" with a
A is of bulb form without
cylindrical portion. These bulbs may be solid as shewn in Figure 14ª or hollow
as shewn in Figure 12", these solid or hollow portions being perforated. In
cases where such forms of sleeves are employed it will be necessary to have the
bearing block recessed out to receive the bulb.
In order to reduce the friction between the ends of the sleeve and the bearing
rings E are provided as shown in Figure 15 and in detail in Figures 15 and 15".
These rings are preferably of circular section and are set free from the shaft or
axle. The rings may be slightly flattened on their inner surfaces to prevent
contact with shaft or axle and should fit the bearing block or standard so as to
revolve freely, the bearing block being formed as described with reference to
Figure 1.
The sleeves may be set to lie wholly within blocks, as described, or may extend
just without the fixed bearings, the shaft or axle in all cases resting solely upon
the revolving sleeve.
In some cases where the sleeves receive the end of a shaft one end of sleeve
may be closed.
The sleeves will be constructed of various diameters and thickness of metal to
suit their particular application to different machinery.
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. A free running sleeve set in a bearing block and encircling a shaft or
spindle substantially as and for the purposes described.
2. A free running sleeve having perforations in a portion of, or portions of, or
hroughout its length, set in a bearing block encircling a shaft or spindle sub-
tantially as and for the purposes described.
"
3. In combination a free running sleeve as
leeve lying within recess of block and encircling a shaft or spindle substantially
A," a recessed block as "B," said
s and for the purposes described.
4. In combination a free running sleeve having a central flange, a bearing block
ecessed to receive the said flange said sleeve being arranged to encircle a shaft
r spindle substantially as and for the purposes described.
5. A free running sleeve provided with a flange or flanges to bear against end
f bearing block and arranged to encircle a shaft or spindle substantially as and
or the purposes described.
6. In combination a free running sleeve having a central enlarged portion or

page_text: bulb, a bearing block recessed to receive the said bulb, said sleeve being arranged
to encircle a shaft or spindle substantially as and for the purposes described.
7. in combination a sleeve, a ring at each end of same, the said sleeves and
rings being set within a recessed bearing block so as to be free to rotate indepen-
dently the said sleeve and rings encircling a shaft or spindle substantially as and
for the purposes described.
