PROVISIONAL SPECIFICATION.
Improvements in Adjustable Bearings for Carrying Shafting.
GEORGE SMITH and EDWIN SMITH Nene Side Iron Works Thrapston
Northamptonshire Eugineers do hereby declare the nature of this invention to be
as follows:-
:-
The object of our "invention is to provide a bearing which shall be adjustable
vertically by hand, and shall be also capable of free oscillation in any plane, to suit
shafting which may not be in true alignment. The invention to be applicable
to plummer blocks, hangers, wall boxes, wall brackets, or any other form of bracket
or pedestal used for carrying any kind of shafts or shafting.
To carry out our invention we form base of the plummer block, hanger or
bracket with a vertical cylindrical hole screwed internally into which we insert a
screwed socket or plug, the top part of which is formed as a knuckle joint.
On the bottom half of the bearing we form the corresponding part of knuckle
joint, which is thereby attached to the screwed socket or plug, so allowing the
bearing to swivel in a vertical. plane, the screwed, plug is also free to swivel
in a horizontal, plane and the, two movements combined, permit motion in any
other plane.
The screwed socket also provides for vertical adjustment by hand for lining the
shafting.
In some arrangements of our invention we should make the base of the plummer
block or bracket as a circular plug screwed externally and the lower portion of the
knuckle joint would, be formed as a socket screwed internally to fit the plug, the
other parts remaining as above described.
In the bottom piece or base we form an oil catcher and the bearing is hollowed
or recessed at each end from which a passage is made to conduct the waste oil into
the receptacle in base.
Dated this 2nd day of January 1893.

COMPLETE SPECIFICATION.
Improvements in Adjustable Bearings for Carrying Shafting.
We GEORGE SMITH and EDWIN SMITH of Nene Side Iron Works, Thrapston,
Northamptonshire, Engineers 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 object of our invention is to provide a bearing which shall be adjustable
vertically by hand and shall be also capable of free oscillation in any plane to suit
shafting which may not be in true alignment. The invention to be applicable to
plummer blocks, hangers, wall boxes, wall brackets or any other form of bracket or
pedestal.used for carrying any kind of shafts or shafting.
To carry out our invention we form base of the plummer block, hanger, or
bracket with a vertical cylindrical hole screwed internally into which we insert
a screwed socket or plug, the top part of which is formed as a knuckle joint.

Fig. 10 an enlarged view of a portion of Figs. 8 and 9.
Fig. 1. shows a sectional elevation of a complete plummer block consisting
mainly of a bearing A, a plug B, and a socket or base C.
Fig. 2. shows a side elevation of the bearing A detached.
Fig. 3. an elevation of the plug B detached.
Fig. 4. a cross section of the bearing and plug.
The bearing A is formed with lugs for the reception of the fulcrum pin a. which
is held down by an eyebolt b. passing through the plug B. This plug B is screwed
externally to fit a corresponding thread in the socket C. The latter is formed
with a cup c to receive the drip from the waste-oil holes d. and has an emptying
plug e. The knuckle joint and pin a. allow the bearing to swing in a vertical
plane, whilst the plug B allows motion in a horizontal plane, the two together
forming an universal joint. The plug B allows also for vertical adjustment.
In Figs. 1 to 7 inclusive, the socket is stationary, the vertical adjustment
being effected by rotating the plug therein, but in the modification shown in
Figs. 8. 9. and 10. this socket Ċ is free to rotate within an eye or bearing D
formed in the stationary frame. With this latter arrangement the vertical
adjustment is effected by rotating the socket C in its eye or bearing. A set screw h.
locks it in any desired position.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is :-
:-
1. In plummer blocks and other shaft bearings, fitting the bearing to oscillate
in a vertical plane, on a knuckle joint carried on a screwed plug free to rotate
about a vertical axis in a socket which may form a part of the stationary base or
framing or be free to rotate therein substantially as described.
2. The construction and arrangement of plummer block shown in Figs. 1. 2. 3
and 4 of the accompanying drawings, or any mere modification thereof, substantially
as described.
3. The bearing as described in Claim 2 but with the circular plug forming
part of the base and screwed externally and the lower portion of knuckle
joint formed as a socket and screwed internally to fit the plug substantially as
described.

page_text: 4. The bearing as described in Claim 1. in combination with the various
supports shown in Figs. 5. 6. 7. 8. and 9 of the accompanying drawings and
substantially as described.
