Improvements in Bucket Hoisting and Tipping Apparatus for
Steamers.
I, WILLIAM MORISON, of 41 St. Vincent Crescent, Glasgow, in the County of
Lanark, North Britain, Engineer, do hereby declare the nature of this invention to
be as follows, that is to say:-
My said invention relates to apparatus designed for hoisting ashes from the
stoke holds of steamers but which may also be used for hoisting other substances,
and has for its object to improve certain parts of such apparatus.
In apparatus made with my improvements the bucket is raised up the ventilator
or other tube by two ropes or chains which pass through eyes in a horizontal cross
bar. The cross bar, and through it the bucket, is guided by inwardly projecting
flanges of vertical angle irons riveted at diametrically opposite parts to the inside
of the ventilator tube, the ends of the cross bar being each fitted with a pair of
antifriction rollers, one being on each side of the guide flange. At the bottom of
the ventilator tube there are stops to prevent the cross bar from getting out of the
tube, the ropes or chains running through the eyes of the cross bar as far as
required for lowering the bucket to its bottom position.
The ropes or chains are attached to the sides of the bucket at points some
distance below the top of the bucket; and when the bucket, in rising, approaches
its highest position, pins or studs fixed to its top corners at one side engage with
hooks fixed inside of the ventilator tube in a manner to hinge the bucket to the
side of the tube. As the lifting continues the hinge connection makes the bucket
tip over in a manuer to empty its contents into a descending shoot or duct. When
the lowering commences the bucket first turns inwards into its vertical position,
the antifriction rollers on the ends of the cross bar being made by suitable guides,
which are more or less inclined, to engage with the vertical angle-iron guides.
The said vertical guides in combination with the cross bar serve to keep the
bucket steady whilst ascending or descending.

Improvements in Bucket Hoisting and Tipping Apparatus for
Steamers.
I, WILLIAM MORISON, of 41, St. Vincent Crescent, in the County of the City
of Glasgow, North Britain, Engineer, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement, that is to say :—
My said invention relates to apparatus designed for hoisting ashes from the
stoke holds of steamers, but which may also be used for hoisting other substances,
and has for its object to improve certain parts of such apparatus.
In apparatus made with my improvements the bucket is raised up the ventilator or
other tube by two ropes or chains which pass through eyes in a horizontal cross
bar guided by vertical angle irons on the inside of the ventilator tube. When the
bucket, in rising, approaches it highest position, pins or studs fixed at its top

page_text: corners at one side engage with books fixed inside of the ventilator tube in a
manner to hinge the bucket to the side of the tube. As the lifting continues, the
hinge connection makes the bucket tip over in a manner to empty its contents into
a descending shoot or duct.
And in order that my said invention and the manner of performing the same may
be properly understood I hereunto append a sheet of explanatory drawings, to be
hereinafter referred to, and showing bucket hoisting and tipping apparatus as
made with my improvements.
Figure, 1, of the drawings is a horizontal section and Figures, 2, and 3, are
vertical sections, as at right angles to each other, of my improved apparatus. In
these drawings the sanie reference letters are used to mark the same or like parts
wherever they are repeated.
The bucket, A, is raised up the ventilator or other tube, B, by two ropes, C,
which pass through eyes in a horizontal cross bar, D, being guided by passing
through tubes, E, attached to the cross bar. The cross bar, D, and through it the
bucket, A, is guided by inwardly projecting flanges of vertical angle irons, F,
riveted at diametrically opposite parts to the inside of the ventilator tube, B, the
ends of the cross bar, D, being each fitted with a pair of antifriction rollers, G, one
being on each side of the guide flange. At the bottom (not shown) of the ventilator
tube, B, there are stops to prevent the cross bar, D, from getting out of the tube,
the ropes running through the eyes of the cross bar as far as required for lowering
the bucket, A, to its bottom position.
The ropes, C, are attached to pins or studs, H, on the sides of the bucket, A,
at points some distance below the top of the bucket; and when the bucket, A, in
rising, approaches its highest position a rod or bar, J, fixed to its top inner edge
and having journal-like ends, engages with hooks, K, fixed to a shoot or duct, L,
(of which a part is inside of the ventilator tube, B,) in a manner to hinge the bucket
to that part of the shoot or duct. Straps, M, are fixed to the sides of the bucket, A,
between the studs, H, and the bar, J, to strengthen the bucket. As the lifting
continues the hinge connection, J, K, makes the bucket, A, tip over in a manner to
empty its contents into the descending shoot or duct, L, the tube, B, being bulged
outwards so as to give clearance to the bucket when being tipped. The tipping
position of the bucket, A, is indicated by the dotted lines, N. When the lowering
commences the bucket, A, first turns inwards into its vertical position, the anti-
friction rollers, G, on the ends of the cross bar, D, remaining engaged with the
vertical angle-iron guides, F, which are extended sufficiently far up the tube, B, to
be always in contact with the rollers, G, ou the cross bar, D.
The said vertical guides, F, in combination with the cross bar, D, serve to keep
the bucket, A, steady whilst ascending or descending.
The hoisting, guiding, and tipping apparatus may, in some cases, be fitted
without any encompassing tube.
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 :-
In bucket hoisting and tipping apparatus for steamers, the combination of a
bucket, with raising and lowering ropes or chains passing through eyes in a
vertically guided cross bar, the bucket being provided with studs or projections
arranged to engage with fixed hooks, substantially as and for the purposes
herein before described.
