An Improvement in Dust-bins.
I, GEORGE COOPER HARRISON 118, Stebondale Street North Greenwich
London, E. do hereby declare the nature of this invention to be as follows:-
This improvement is designed to facilitate the rapid emptying of dust-bins into
sacks specially made for that purpose, and for protecting the contents of the bins
from rain, thereby preventing heating and fermentation. The body of the bin is
of the ordinary kind made of galvanised iron or other metal and is round in form,
but the handles are placed much lower than usual and about one third of the height
of the bin from the bottom.
The top of the bin is so formed as to be easily and quickly removed when the
bin requires to be emptied. It may consist of a hinged lid which can be taken off
on withdrawing a pin, or the top of the bin may be composed of a hoop of metal
which carries a hinged lid guarded by stops to prevent it being carelessly left open.
The hoop may be notched on its lower edge with curved or L shaped notches
which fit on to studs near the upper margin of the bin, in such a way that a slight
rotary movement of the hoop or cap locks it into place.
When the bin is to be emptied the hoop or cap is removed entire, the sack is
drawn over the top of the bin and attached to the studs, the bin is lifted from the
ground and turned upside down while the contents fall into the sack, which is
then detached and the mouth closed ready for removal to the cart on which it is
taken to the destructor or other receptacle, without being opened, till it arrives
at its destination.
Protection is asked for this improvement on sanitary grounds, the object being
to remove the dust without its being blown about or otherwise scattered, thus
reducing the risk of infection.

An Improvement in Dust-bins.
1 GEORGE COOPER HARRISON, of 118 Stebondale Street, North Greenwich,
London E., Doctor of Medicine, do hereby declare the nature of my said inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This improvement is designed to facilitate the rapid emptying of dust-bins into
sacks specially manufactured for the purpose; and for protecting the contents of
the bins from rain, thereby preventing heat and fermentation.
And in order that my said invention may be particularly described and
ascertained, reference is hereby made to the accompanying drawings, in which
similar letters of reference indicate corresponding parts.

page_text: Fig. 2 is a plan of the cover.
Fig. 3 is a sectional elevation.
Fig. 4 is a section on the line a b, showing the underside of the cover.
Fig. 5 illustrates the method of attaching the sack to the bin, in order to empty
the contents of the bin into the sack.
c is the cylindrical portion of the bin. d is the cover consisting of a ring having
a fixed semi-circular plate e, to which the semi-circular flap is hinged. The
flap has a stop g to prevent it being raised too far, and to render it self closing
after being raised by hand for the insertion of ashes &c. is a bar fixed to the
underside of the plate e. Two short bars kk are pivoted at m m. The pivots
are fitted with locking appliances for turning the bars kk, the key being intended
to be in the possession of the dustman. The bars k secure the position of the
cover by being locked under the inner ring n fixed inside the upper end of the bin.
The objects of this arrangement are those of keeping the bin covered, preventing
the entrance of rain, and the escape of dust &c.
The handless (one on each side) are preferably placed about one third of the
height from the bottom, to facilitate the removal of the contents into the
sack.
When the bin is to be emptied the cover is removed entire, the sack p is then
drawn over the top of the bin, as shown in Fig. 5, the strap r being used to secure
the sack in position. The bin is then lifted from the ground and inverted, the
contents of the bin falling into the sack, which is then detached, and the mouth
closed by means of the strap, for removal to the cart, by which it is taken
to the destructor or other receptacle, without being opened until it arrives at its
destination.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to he performed, I declare that what I
claim is :-
1. The improved dust-bin substantially as and for the purposes described.
2. In a dust-bin, the combination of a cover capable of being locked to the
cylindrical portion of the bin, and having a hinged, self-closing, door or flap for
the insertion thereinto of refuse, substantially as hereinbefore described and
illustrated by the drawings.
