PROVISIONAL SPECIFICATION.
Improvements in Bearings for Revolving Shafts and in Carriers
therefor.
I ARTHUR GEORGE BROWN of Globe Iron Works, Bolton, in the County of
Lancaster, Engineer, do hereby declare the nature of this invention to be as
follows:-
The objects of my present invention are to provide self lubricating bearings for
shafts, and also to construct carriers for bearings so that the said bearings are
adjustable in any required direction.
My invention consists first in constructing a bearing with end chambers and
with wells or passages leading from the said end chambers towards the centre,
in fitting on the shaft within the said chambers, rings, flanges, or other suitable
devices for forcing, driving, or directing the oil which would flow out of the
ends of the bearing into the said wells or passages, and with means for raising
the oil from the wells or passages near the centre of the bearing and feeding
the said oil to the shaft. Wicks, screws, paddles, wings and like devices are
available for feeding.
Under the second part of my invention bearings for shafts are made with curved
surfaces above and below the line of the shaft, against which, bear hollow blocks.
The said blocks are held in position by screws, wedges, or their mechanical
equivalent provided with nuts or locking devices. The said screws or their
equivalent pass through slots or ways in brackets secured to, or made as part of
the carriers, and are adjusted and held in position by the said nuts or locking
devices.
In place of the blocks and screws above mentioned, screwed tubes may be used.

Improvements in Bearings for Revolving Shafts and in Oarriers
therefor.
I, ARTHUR GEORGE BROWN of Globe Iron Works Bolton in the County of
Lancaster, 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 :—
The objects of my present invention are to provide self-lubricating bearings for
shafts and also to construct carriers for bearings so that the said bearings are
adjustable in any required direction.
My invention consists first in constructing a bearing with end chambers and
with wells or passages leading from the said end chambers towards the centre,
in fitting on the shaft within the said chambers, rings, flanges, or other suitable
devices, for forcing, driving or directing the oil which would flow out of the ends
of the bearing into the said wells or passages, and with means for raising the
oil from the wells or passages, near the centre of the bearing and feeding the said
oil to the shaft. Wicks, screws, paddles, wings and like devices are available for
feeding.
Under the second part of my invention bearings for shafts are made with curved
surfaces, above and below the line of the shaft, against which bear hollow blocks.

page_text: The said blocks are held in position by screws, wedges, or their mechanical
equivalent provided with nuts or locking devices. The said screws or their
equivalent pass through slots. or ways in brackets secured to or made as part of
the carriers, and are adjusted and held in position by the said nuts or locking
devices.
In place of the blocks and screws above mentioned, screwed tubes may be used.
DESCRIPTION OF THE DRAWINGS.
Figs. 1 and 2 are elevations at right angles to each other, parts being in section of
bearings and carriers under my invention. Under the first part, the bearing con-
sisting of upper and lower portions a a¹ is made with end chambers 6 6¹ with wells
or passages c leading from the ends towards the centre. d is the shaft provided
with rings or flanges e which fit within the chambers 6 6¹ and by centrifugal action
force or direct the oil into the said wells or passages c. f are ways leading from
the wells c to the top of the shaft as shown more particularly in the section
Fig. 3.
9 are wicks for raising the said oil by capillary action from the said
wells to the shaft. are pieces for keeping the wicks in contact with the shafts.
I prefer to use wicks but any of the usual feeding devices may be used instead if
desired.
Under the second part of my invention the bearing a, a¹ is made with curved
surfaces i against which bear hollow blocks j. The said blocks j are held in position
laterally by screws k and locknuts . The said screws pass through brackets m
cast on the carrier n. The said brackets may be made separate from the carriers
and be bolted or otherwise secured thereto, vertical adjustment is obtained by
making the blocks j with a screw thread which fits within a nut o against which
the lateral adjustment-screws k abut.
Figure 4 is a transverse section showing both lateral and vertical adjustment of
a block by means of screws k abutting directly against it.

Figure 5 is a view showing a block with a screwed pin p which passes through
a slot
in the bracket and is adjusted vertically by lock-nuts l.
Figure 6 is a view showing a block; adjusted vertically by means of a screwed
end piece as in Figure 4, but adjusted laterally by means of a screw k which passes
through the said block and abuts at one end against the bracket m, and at the other
end against a block r which is free to move to and fro in a way or slot ql in the said
bracket m.
Figure 7 is a view in which vertical adjustment is obtained by forming the block j
with a screwed end p passing through ways in the bracket and having adjusting
lock nuts above and below the bracket, whilst lateral adjustment obtained by a
screw k which passes through the stem of the block j and has a head s free to move
up and down in a slot q' in the carrier n.
Figure 8 is a view in which the block j fits freely within a cup and which is
adjusted laterally by screws & passing through the bracket whilst the said block is
adjusted vertically by a screw k passing through the cup. The cup and the nut o
in Figs. 1 and 2 have flanges o' which rest on the tops of the brackets m.
Figure 9 is a view in which the block j is constructed as set forth under Fig. 7
for vertical adjustment and is held in position laterally by means of the lock nut /
without special means of adjustment.
Figure 10 is a sectional view of a bearing in which the blocks here made of a
screwed tube are adjusted as set forth in Figure 9.
The top and bottom blocks may be made alike or different from each other and
may be lined with antifriction metal or otherwise.
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 :-
First. Bearings having end chambers, wells or passages, and oil feeding devices
substantially as set forth.

page_text: Second. The combination of bearings having end chambers, and oil feeding
devices with shafts having ways and flanges or their equivalents, substantially as
set forth.
Third. The combination carriers for bearings having brackets and adjustable
blocks substantially as set forth.
Fourth. The combination of carriers and bearings substantially as herein set
forth.
