PROVISIONAL SPECIFICATION.
A New or Improved Tipping Bucket for Lifting and Discharging
Coal and other Materials.
I, WILLIAM THOMAS ANDREWS, Malvern, Queen's Road, Leytonstone, Essex,
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention consists of a method of suspending a bucket, tank, or similar
receptacle for craning hoisting, and tipping coal, earth, or other material, in such
a manner that the usual side slings or supporting bars, are dispensed with. This
purpose I effect by hanging the bucket, tank, or similar receptacle upon a single
rod or bar, so placed that the centre of gravity of the whole is approximately in
the line of the axis of the said rod or bar. The suspending bar is passed through
a pocket or recess in the side of the bucket and surrounded by a suitably shaped
division plate in such a manner that the bucket is free to fall on one side
sufficiently for discharging the material within. The suspending rod is attached
to the bucket by a revolving hinge or pin near its lower end and the bucket is
normally kept in a vertical position by means of a moveable catch.
Dated this First day of March 1894.

A New or Improved Tipping Bucket for Lifting and Discharging
Coal and other Materials.
I, WILLIAM THOMAS ANDREWS of Malvern, Queen's Road, Leytonstone,
Essex, 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 :-
According to my invention I construct. tipping buckets for lifting and discharging
coal, earth and other materials in such manner that the usual side slings or
supporting bars or bails are dispensed with which are weak in form and are in the
way and often cause accidents to the men by cutting off or lacerating their fingers
between the bails or their catch and the side of the bucket. For this purpose I
hang the bucket, tank or similar receptacle upon a single rod or bar at or near the
vertical line of the centre of gravity of the bucket. Such a bar inay be made very
light and nevertheless afford much greater strength than the weak bail form now
in use. The suspending bar is passed through a pocket or recess in the side of the
bucket and surrounded by suitably shaped division plates in such manner that the
bucket is free to fall on one side sufficiently for discharging the material within.
The suspending rod is jointed to the bucket near the lower end of the bucket and
the latter is normally kept in a vertical position by means of a movable catch.
Fig. 1 of the accompanying drawings is a vertical section and Figure 2 a plan
view of a bucket constructed according to my invention.
The bucket A is formed with a pocket B or recess in one side and in this recess
the bucket suspending rod C is jointed near the lower end of the bucket, the joint
ID: 0

page_text: pin C passing through the side plates A'A' which enclose or surround the pocket
forming its sides. The rod C is attached a little beyond the centre line a a so as
to be about in the line of the centre of gravity. The eye C in its upper end is by
preference made elongated as shown for the purpose of easily introducing the hook
at the end of the hoisting chain. The back plate A2 of the pocket is by preference
carried up a little above the level of the top of the bucket and the side plates A' A'
of the pocket are made to slope down to said level; by this means the coals may
be heaped without being liable to tumble into the pocket, when the ucket is being
loaded.
The underside of the bucket is fitted with castors by_preference of the form
shown. The body of the castor is a hollow ball casting E mounted so as to turn
freely on a pin F which passes through the sides of a bracket G. This construction
of castor is strong and simple, does not catch against inequalities of the ground
and permits the bucket to be slided rather freely on the ground. The interior of
the ball may form an oil reservoir which is charged with oil through a small
hole E'. D is a catch or latch which turns on a joint pin and serves to keep the
rod C in place; when it is raised up out of the way the bucket is free to be tipped
over on one side for discharging its contents. Any other suitable form of latch or
catch may be used for holding the rod C in place.
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 tipping bucket with a pocket wherein is jointed a rod whereby the bucket
is suspended which serves for attachment to the hoisting chain substantially as and
for the purpose set forth.
2. The construction of tipping bucket with suspending rod and pocket as
illustrated by the drawing.
3. The combination with a bucket constructed as described of castors of the
form shown.
