Improved Axle Bearing for Tip Wagons.
I, HENRY OSBORNE BALDRY, of 21, Queen Anne's Gate, Westminster, in the
County of Middlesex, Civil Engineer and Contractor, do hereby declare the
nature of this invention to be as follows:-
This invention relates to bearings for axles for tip wagons, more particularly
for side tip wagons of the description known as ship canal wagons. In such
wagons the bearing for the axle is usually placed on the inside of the wheel.
The ordinary contractors wagon is lubricated by the direct application of the
fat to the axle, which has to be renewed at short intervals, as the wagons will
only run a comparatively short distance without the axle heating, if not re-
lubricated.
The objects of the present invention are:--to provide for the storage of lubri-
cant, for the passage of the lubricant from the stored supply to the axle, for
readily removing and renewing the bearing surface, and economy in lubricant
and repairs; all of which make a contractors wagon fitted with this invention.
equal to an ordinary ballast-or railway truck as regards ease in running and
in distance travelled without requiring addition to the original supply of
lubricant; and this without interfering with the special employment of the
wagon for tipping purposes.
An axle bearing constructed according to the present invention consists of a
brass or other anti-friction metal bearing block, fitted in a cast iron pedestal,
in general size, position of bolt holes and exterior shape similar to the solid
pedestals commonly in use with the Manchester pattern of side tip wagons.
The upper part of the pedestal above the bearing block is cast hollow, to form a
grease box for storing the lubricant, and with a curved continuation or spout at
the inner side for the introduction of the lubricant into the grease box, which
is closed by a hinged lid.
The bearing block is made in the shape of a long truncated wedge, the trun-
cated face, which is the bearing face, being curved to the radius of the axle, or a
little flatter. The top side of the bearing block is therefore widest. A dove tail
shaped recess or cavity, of the same size as the bearing block, is cast in that
part of the pedestal directly over the axle; extending from the inner side to
within about 5ths inch of the outer side of the pedestal; a rib of this thickness
being left at the outer side. The underside of this rib is curved to the radius
of the axle or thereabouts; the centre of the curve coinciding with the centre
of the axle, when the bearing block has worn down so far, that it is deemed
advisable or becomes necessary to renew the latter. The length of the dove tail
shaped recess or cavity and the length of the bearing block are the same, and
equal to the length of the pedestal from side to side less the thickness of the
aforesaid rib. The inner end of the bearing block is thus flush with the inner
side of the pedestal, and the former is secured in the recess by a strap bolted

page_text: across the inner end of the bearing block to the inner side of the pedestal. This
strap is hollowed out on the under side in the same manner as the rib.
The bearing block is inserted in position endways from the inside.
This construction permits of the bearing block being readily withdrawn when
worn out, and of the insertion of a new one.
Two holes to form passages for the grease are cast through the bottom of the
grease box, and two similar holes are cast in the bearing block, respectively
coincident with the holes in the bottom of the grease box; through which lubri-
cant passes from the grease box to the top of the axle. Diverging ducts or
chases are cut in the bearing surface of the block, to distribute the lubricant
over the whole length of the axle journal.

Improved Axle Bearing for Tip Wagons,
I, HENRY OSBORNE BALDRY, of 21, Queen Anne's Gate, Westminster, in the
County of Middlesex, Civil Engineer and Contractor, 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 relates to bearings for axles for tip wagons, more particularly
for side tip wagons of the description known as ship canal wagons. In such
wagons the bearing for the axle is usually placed on the inside of the wheel.
The ordinary contractors wagon is lubricated by the direct application of the
fat to the axle, which has to be renewed at short intervals, as the wagon will
only run a comparatively short distance without the axle heating, if not re-
lubricated; the amount of fat which can at one time be directly applied to the
bearing, being comparatively small.
The objects of the present invention are:--to provide for the storage of lubri-
cant, for the passage of the lubricant from the stored supply to the axle, for
readily removing and renewing the bearing surface, and economy in lubricant
and repairs; all of which make a contractors wagon fitted with this invention
equal to an ordinary ballast-or railway truck as regards ease in running and
in distance travelled without requiring addition to the original supply of
lubricant; and this without interfering with the special employment of the
wagon for tipping purposes.
An axle bearing constructed according to the present invention consists of a
brass or other anti-friction metal bearing block, fitted in a cast iron pedestal ;
in general size, position of bolt holes and exterior shape, similar to the solid
pedestals commonly in use with the Manchester pattern of side tip wagons.
The upper part of the pedestal above the bearing block is cast hollow, to form a
grease box for storing the lubricant, and with a curved continuation or spout at
the inner side for the introduction of the lubricant into the grease box, which
is closed by a hinged lid.
The bearing block is made in the shape of a long truncated wedge; the trun-
cated face, which is the bearing face, being curved to the radius of the axle, or a
little flatter. The top side of the bearing block is therefore widest. A dovetailed
shaped recess or cavity, of the same size and shape as the widest part of the
bearing block, is cast in that part of the pedestal directly over the axle; extend-
ing from the inner side to within about five eighths of an inch of the outer side

page_text: cavity having its supply opening on the inner side of the pedestal, a dovetail
shaped recess on the underside in the centre of the pedestal, said recess stopping
short of the outer side, but extending through to the inner side of the pedestal,
and a truncated wedge shaped bearing block fitting with its wider surface
uppermost into said dovetail shaped recess, and secured in said recess by a plate
bolted across it to the inner side of the pedestal, all substantially as herein set
forth and illustrated in the accompanying drawings.
2. In axle box pedestals for tip-wagons the formation of a grease box cavity in
the upper part of the pedestal with an upwardly bent or curved prolongation
of the cavity on the inner side of the pedestal, for the purpose of enabling the
lubricant to be introduced on the inner side from the exterior of the wagon when
the body of the wagon is tilted, substantially as set forth and illustrated.
3. In axle box pedestals for tip-wagons the formation of a dovetail shaped
recess on the underside in the centre between the depending sides or legs of the
pedestals, said recess stopping short of the outer side so as to leave a projecting
rib, but extending fully through on the inner side so as to admit of the intro-
duction or withdrawal at the inner side of the pedestal of a truncated wedge
shaped bearing block, fitting with its upper wider surface in said recess, and with
its under surface curved to form a bearing surface for the axle; said bearing
block being secured by a plate bolted across it to the inner side of the pedestal,
and hollowed out at the centre to allow clearance as the bearing block wears
thinner; all substantially as herein set forth and illustrated.
4. The construction of axle bearings for tip-wagons substantially as set forth
and illustrated in the accompanying drawings.
