Year: 1884

page_text: I, DONALD NICOLL of Backingham Street Strand in the city of Westminster,
Parliamentary Agent, do hereby declare.the nature of my invention for "IMPROVE-
MENTS IN APPARATUS FOR DEODORISING AND DISINFECTING THE CONTENTS OF
DUST BINS AND OTHER RECEPTACLES FOR REFUSE," to be as follows:-
My invention has for its object to distribute periodically over the contents of
dust bins and other receptacles for refuse disinfecting or deodorising substances in
a pulverulent condition, such as powdered charcoal chloride of lime and the like.
For this purpose, I arrange inside the dust-bin or other receptacle, at the upper
part thereof, a partly perforated cylinder or box which is filled with the pulverulent
disinfectant and which is so arranged in connection with the cover of the dust-bin,
that on opening or closing the same a rotary or reciprocating motion is imparted to
the cylinder or box so as to distribute some of the contents thereof on to the refuse
thrown in. Various arrangements may be employed for imparting the said motion
to the cylinder or box; thus in the case of a cylinder, the axis thereof may be
connected to one end of a volute spring, the other end of which is fixed to the side
of the dust bin, and a cord having its one end attached to the cover may have its
other end wound round a grooved pulley fixed at one end of the cylinder, so that
on opening the cover the cord will be made to turn the cylinder in one direction,
thereby winding up the spring, while, on closing the cover again the spring will
cause the cylinder to revolve in the contrary direction, thereby winding up the
cord on the pulley again. Or, in the case of a reciprocating box, the said spring
and pulley with cord may be fixed on a spindle having one or more cranks that are
connected by rods to the box, which may either be suspended by wires, or rest
upon guides, so that by the rotation of the crank spindle a rapid to and fro motion
is imparted to the box. Or instead of imparting the motion of the cover of the
dust-bin to the spindle, by means of a pulley and cord acting in combination with
a spring the cover may have a toothed bar attached to it in gear with a small
pinion on the spindle.
In order to prevent unpleasant effluvium from escaping from the dust bin when
closed, the opening thereof has a rim surrounding it on which is fixed a strip or
fillet of india-rubber, so that the cover, on closing down upon such slip or fillet of
indiarubber, will effect the more or less perfectly air tight closing of the dust bin.

page_text: I, DONALD NICOLL of Buckingham Street, Strand in the City of Westminster,
Parliamentary Agent, do hereby declare the nature of my invention for "IMPROVE-
MENTS IN APPARATUS FOR DEODORISING AND DISINFECTING THE CONTENTS OF
DUSTBINS AND OTHER RECEPTACLES FOR REFUSE" and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement:—
My invention has for its object to distribute periodically over the contents of
dustbins and other receptacles for refuse disinfecting or deodorising substances in a
pulverulent condition, such as powdered charcoal, chloride of lime, and the like.
For this purpose, I arrange inside the dust bin or other receptacle, at the upper
part thereof, a partly perforated cylinder or box which is filled with the pulverulent
disinfectant and which is so arranged in connection with the cover of the dust bin,
that on opening or closing the same a rotary or reciprocating motion is imparted
to the cylinder or box so as to distribute some of the contents thereof on to the
refuse thrown in.
Various arrangements may be employed for imparting the said motion to the
cylinder or box; thus in the case of a cylinder, the axis thereof may be connected
to one end of a volute spring, the other end of which is fixed to the side of the dust
bin and a cord having its one end attached to the cover may have its other end
wound round a grooved pulley fixed at one end of the cylinder so that on opening
the cover the cord will be made to turn the cylinder in one direction thereby
winding up the spring, while on closing the cover again, the spring will cause the
cylinder to revolve in the contrary direction, thereby winding up the cord on the
pulley again. Or, in the case of a reciprocating box, the said spring and pulley
with cord may be fixed on a spindle having one or more cranks that are connected
by rods to the box, which may either be suspended by wires, or rest upon guides,
so that by the rotation of the crank spindle a rapid to and fro motion is imparted
to the box. Or instead of imparting the motion of the cover of the dust bin to the
spindle by means of a pulley and cord acting in combination with a spring, the
cover may have a toothed bar attached to it in gear with a small pinion on
the spindle or the spindle of the cylinder can be made to revolve by means of
leather or other belting.
In order to prevent unpleasant effluvium from escaping from the dust bin when
closed, the opening thereof has a rim surrounding it on which is fixed a strip,
fillet or tubing of india-rubber, so that the cover on closing down upon such strip,
fillet or tubing, will effect the more or less perfectly air tight closing of the
dust bin.
Fig. 1 of the accompanying drawing shews a perspective view of one arrangement
of my improved dust bin or receptacle for refuse provided with means for deodo-
rising or disinfecting the contents. For this purpose there is provided in the lid of
the receptacle a cylinder A, about one half of the surface of which is formed with
perforations, and which is filled with powdered disinfecting or deodorising material

page_text: through the door B. The cylinder is free to revolve on its pivots, to one of which
is connected the inner end of a volute spring, whose other end is attached to the
lid. On the pivot is also fixed a grooved pulley C round which is coiled a cord D
whose end is connected to the hook E on the receptacle. Thus when the lid is
opened, the cord causes the cylinder A to revolve, thereby scattering a portion of
the disinfectant over the contents of the dust bin.
As by this rotation the spring attached to the pivot of the cylinder is wound up,
it follows that when the lid is closed down again, the spring will cause the
cylinder to revolve in the contrary direction, thereby scattering a further quantity
of disinfectant over the contents of the dust-bin, and at the same time winding the
cord up on the pulley again. Upon the rim of the dust bin is fixed a strip of
caoutchouc F upon which the lid closes down in an air tight manner, so as to
prevent any effluvium from escaping,
Fig. 2 shews another arrangement in which the disinfecting powder is contained
in a box G, arranged to slide backwards and forwards upon guides H, the requisite
rapid to and fro motion being imparted to it on the opening and closing of the lid
by means of a crank I and connecting rod J, actuated by a lever K, connected by a
cord or chain L to the lid of the dust bin and held by a spring M, so that when the
lid has been opened to a certain extent the cord in tightening will raise the arm K
so as to move the box G rapidly over to the dotted position, and on closing the lid
again the spring M in drawing back the arm K will cause the box to move back to
its original position again. The box G has a spring N to assist in the return motion.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed I declare that what I claim is
The use in combination with dust bins or receptacles for refuse, of a perforated or
wire gauze cylinder or box containing disinfecting or deodorising powder, and so
arranged that on opening or closing the lid of the receptacle a rotary or recipro-
cating motion is imparted to the cylinder or box so as to distribute some of the
powder over the contents of the dust bio, substantially as herein described.
