IMPROVEMENTS IN COAL TUBS OR COLLIERY WAGONS
Year: 1876

page_text: LETTERS PATENT to Samuel Woodall, of the Windmill End Works, Dudley, in
the County of Worcester, for the Invention of "IMPROVEMENTS IN COAL TUBS
OR COLLIERY WAGONS."
Sealed the 1st September 1876, and dated the 6th March 1876.
PROVISIONAL SPECIFICATION left by the said Samuel Woodall at the Office
of the Commissioners of Patents on the 6th March 1876.
SAMUEL WOODALL, of the Windmill End Works, Dudley, in the County of
Worcester. "IMPROVEMENTS IN COAL TUBS OR COLLIERY WAGONS."
This Invention relates to certain improvements in wrought iron coal tubs or
colliery wagons, designed for the purposes of rendering such tubs or wagons much
lighter and easier to be handled, and stronger in their construction than those
hitherto in use.
The improvements consist in affixing to and underneath the bottom plate of the
tub or wagon steel pedestals, brackets, or bearings, in which the axles of the
travelling wheels work, and in fitting to and above the said bottom plate wrought
or cast iron boxes in which the said wheels work, and in the application to and
outside the end plates of the said tub or wagon of wrought iron, buffers which are
supported by internal stays and secured by rivets. If required, the said wheels
may be made fast to the axles, and provided or titted with grease boxes.
The advantages derived from the application of these improvements are as
follows: The wooden feet or buffers now in use are dispensed with, and a depth
of about five inches is thus gained to the tub, which increases its carrying capacity
about 15 to 20 per cent. without increasing its size in such a manner as to take
more room in the cage. The usual ring bolts are also dispensed with. The tub or
wagon is also rendered much lighter and easier to be handled at the same time
being stronger in its construction. The friction is also greatly reduced, and the
bearing surfaces wear very much longer. And in shallow tubs the carrying capacity
is increased about 50 per cent.

SAMUEL WOODALL, of the Windmill End Works, Dudley, in the County of
Worcester. "IMPROVEMENTS IN COAL TUBS OR COLLIERY WAGONS.
This Invention relates to certain improvements in wrought iron coal tubs or
colliery wagons, designed for the purposes rendering such tubs or wagons much
lighter and easier to be handled and stronger in their construction than those
hitherto in use.
The Invention is illustrated on the accompanying Sheet of Drawings in Figures
1 to 3, which are drawn to a scale of one inch and a half to the foot, and of which
Figure 1 represents a side elevation partly in section, Figure 2 an end elevation,
also partly in section, and Figure 3 a plan view.
The improvements constituting this Invention consist in affixing to and under-
neath the bottom plate 1 of the tub or wagon 2 steel pedestals, brackets, or
bearings 3, in which the axles 4 of the travelling wheels 5 work; and in fitting to
and above the plate 1, wrought or cast iron boxes 6, in which the wheels 5 work;
and in applying to and out side the end plates 7 of the tub or wagon, wrought iron
buffers 8, which are supported by internal wrought iron stays 9, and secured by
rivets 10. The wheels 5 may be made fast to the axles 4, and they may be provided
with grense boxes at 11.
The advantages derived from the application of these improvements are in their
combination somewhat important and as follows:-The wooden feet or buffers in
ordinary use are dispensed with, and a depth of about five inches is thus gained to
the tub, which increases its carrying capacity about 15 to 20 per cent. without
increasing its size in such a manner as to take up more room in the usual cage.
The usual ring-bolts are also dispensed with. The tub or wagon is also rendered
much lighter and easier to be handled, and stronger in its construction.
friction is also greatly reduced, and the bearing surfaces wear very much longer.
And in shallow tubs the carrying capacity is increased about 50 per cent. on those
hitherto in usc.
The
Having now described the nature and objects of my said Invention for "Improve-
ments in Coal Tubs or Colliery Wagons," together with the manner in which the
same is to be or may be performed or carried into practical effect, I would remark in
conclusion that I clain as my Invention-
The application and combination with a wrought iron coal tub or colliery wagon
of the bearings 3, boxes 6, buffers 8, and stays 9, substantially as described, and as
illustrated on the accompanying Drawings and for the purposes respectively specified.
In witness whereof, I, the said Samuel Woodall, have hereunto set my hand
and seal, this Fifth day of September, in the year of our Lord One thousand
eight hundred and seventy-six.
SAMUEL WOODALL. (L.S)
