I WILLIAM ALBERT MATHER, of 93 Lytham Road, South Shore, Blackpool, in the
County of Lancaster, Baker, do hereby declare the nature of this invention to be
as follows:-
-
This invention relates to that kind of weighing machine used by grocers and
others for automatically weighing and delivering certain definite quantities of
goods, such as sugar, tea, &c., to expedite the making up of such goods into
packets of any desired weight; and the object of my invention is to construct an
inexpensive and simple but accurate machine for the above purpose.
I use a balanced beam suitably weighted at one end and provided with a scoop
or receptacle for the goods at the other end.
This receptacle is held up normally by the weight beneath a fixed hopper con-
taining the goods in bulk and provided at the bottom with an adjustable outlet
or feed. regulator leading to a short shoot, the lower end of which is closed by an
inclined plate or flap hinged to the inner or short side of the said shoot.
This plate or flap is normally, open, when the machine is in use, and is pro-
vided with a suitably formed arm or projection hanging from it in such a posi-
tion that when enough of the goods has been delivered by the shoot, the receptacle
will fall and tilt outwards, and a projection or arm is provided at the back of
the same in such position and of such form as to act on the projection or arm
attached to the plate or flap of the shoot in such a manner as to close the open
end of the shoot and prevent further delivery of the goods..
The scoop or receptacle is so formed that, when it descends full, the contents
can fall from its outer end and thus be delivered into a bag placed ready for the
reception of the same, and I prefer to provide the balanced receptacle or scoop
with a flap at the outer side, so hung upon a pivot at the top as to hold the goods
in the scoop or receptacle whilst the latter is being filled, but to hang back when
the receptacle falls, and make way for its contents to pass to empty the said
receptacle or scoop.
If the apparatus is to be used in conjunction with an automatic delivery shoot,
the feed regulator at the bottom of the hopper may be dispensed with.
It will be understood from the above description that the attendant has only
to remove each packet or bag as it is filled by the machine and place an empty
packet or bag in the place thereof, and while the latter.is being filled he can
fasten up the full packet or bag ready for sale or carriage, and the speed of

page_text: delivery of the machine may be regulated according to the speed at which the
attendant can perform these operations.

"Improvements in Weighing Machines."
I WILLIAM ALBERT MATHER, of 93 Lytham Road, South Shore, Blackpool, in the
County of Lancaster, Baker, do hereby declare the nature of this invention to be
as follows:-
-:
This invention relates to. that kind of weighing machine used by grocers and
others for automatically weighing and delivering certain definite quantities of
goods, such as sugar, tea, &c., to expedite the making up of such goods into
packets of any desired weight; and the object of my invention is to construct an
inexpensive and simple but accurate machine for the above purpose.
My invention will be readily understood from the following description on
reference to the accompanying drawings.
I use a balanced beam a a¹ preferably in the form shewn on the drawing suit-
able weighted at one end a¹ and provided with a scoop b or receptacle for the goods
at the other end.
This receptacle 6 is held up normally (by the weight put up
on a¹) beneath a
fixed hopper c containing the goods in bulk preferably arranged in combination
with a shoot or conveyor for supplying the said goods thereto and provided at
the bottom with an adjustable outlet or feed regulator c¹ leading to a short shoot
the lower end of which is closed by an inclined plate or flap c³ hinged at c to the
inner or short side of the said shoot c³.
a
This plate or flap is preferably counter balanced by a weight c5 and is held
normally open as shewn, when the machine is in use and it is also provided with
suitably formed arm or projection fixed on the same centre, and hanging
from it in such a position that when enough of the goods has been delivered by
the shoot, the receptacle 6 will fall and tilt outwards as shewn by dotted lines
and a projection or arm 61 preferably fitted with a bowl be, is provided at the
back of the same in such position and of such form as to act on the projection or
arm attached to the plate or flap of the shoot in such a manner as to close
the open end of the shoot and prevent further delivery of the goods.
The scoop or receptacle is so formed that, when it "descends full, the con-
tents can fall from its 'outer end and thus be delivered into a bag d placed ready
for the reception of the same, and I prefer to provide the balanced receptacle b
or scoop with a flap at the outer side, so hung upon a pivot at 64 at the top as
to hold the goods in the scoop or receptacle 6 whilst the latter is being filled, but
to hang back when the receptacle falls, and make way for its contents to pass to
empty the said receptacle or scoop. b.
A pivotted conical mouthpiece or funnel e may be fitted to guide the goods
into the bag. d. The block f limits the action of the beam a a
If the apparatus is to be used in conjunction with an automatic delivery shoot,
the feed regulator at the bottom of the hopper may be dispensed with.
It will be understood from the above description that the attendant has, only
to remove each packet or bag as it is filled by the machine and, place an empty
packet or bag in the place thereof, and while the latter is being filled he can
fasten up the full packet or bag ready for sale or carriage, and the speed of

page_text: delivery of the machine may be regulated according to the speed at which the
attendant can perform these operations.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
The improved automatic self supplying weighing machine constructed and
operating substantially as hereinbefore described.
