PROVISIONAL SPECIFICATION.
Improved Method of and Apparatus for Weighing Granulated Sugar
and other Suitable Substances or Materials.
I, JOHN JAMES MARSHALL, of 60 Church Street, Hunslet, Leeds, in the
County of York, Grocer, do hereby declare the nature of this invention to be as
follows:-
My invention has reference to improved method of and apparatus for weighing
granulated sugar and other suitable substances or materials.
In carrying out my invention I employ scales or weighing apparatus in com-
bination with an electric arrangement and other parts, such as hereinafter set
forth.
Affixed to the underside of the scale pan holding the goods is a suspended cross
piece free to slide on its suspenders, and underneath the said cross piece are two
uprights, rods, or pillars, connected with a battery from which the necessary
electricity or power is obtained.
Arranged conveniently above the scale pan for the goods is a hopper fitted with
a sieve and having a funnel, tube or spout which is provided with a slide or
cut off which is operated by the electric current.
The said slide or cut off is provided with a rod (passing through terminals)
which engages with a pivotted lever or rod connected with an electro-magnet or
electro-magnets.
The various parts of the electric arrangement are connected with wires or com-
municators in the usual way.
The action is as follows:-
When the requisite weight of material has been obtained the scale pan carrying
such descends and the suspended cross piece comes in contact with the uprights,
rods, or pillars, thus completing the circuit, and thereby operating the electro-
magnet which actuates the pivotted lever or rod, whereby the slide or cut off is
made to close the funnel, spout or tube, which can be again opened by pushing
the slide or cut off back by hand or otherwise.
Further, the scale pan for holding the goods may be provided with means for
obtaining the necessary balance, I may also provide the scales with a screw
balance or suitable rod or lever fitted with screw or screws to obtain or adjust the
balance.

Improved Method of and Apparatus for Weighing Granulated Sugar
and other Suitable Substances or Materials.
I, JOHN JAMES MARSHALL, of 60 Church Street, Hunslet, Leeds, in the
County of York, Grocer, 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:-
My invention has reference to improved method of and apparatus for weighing
granulated sugar and other suitable substances or materials.

forth.
DESCRIPTION OF DRAWINGS.
Fig 1, is an end elevation in section showing my invention as carried out.
Fig. 2, is a back elevation of Fig. 1, showing door removed.
Fig. 3, is an enlarged sectional elevation of funnel.
Figs. 4 and 5 are detail views of means employed for balancing purposes, and
for raising the bags to proper height on scale pan.
Affixed to the underside of the scale pan A, holding the goods is a suspended
cross piece B free to slide on its suspenders C, and underneath the said cross
piece B are two uprights, rods or pillars D connected with a battery E as herein-
after set forth from which the necessary clectricity or power is obtained. Arranged
conveniently above the scale pan for the goods is a hopper G fitted with a sieve H,
and having a funnel tube or spout J, which is provided with a slide or cut off K
which is operated by the electric current.
The said slide or cut off is provided with a rod L (passing through bearings L₁
and L2) which engages with a pivotted double forked lever or rod M, the said
lever is pivotted to the bearing M' which carries the electro-magnet or electro-
magnets N. N³ is the armature.
Connected with the rod L are springs N¹ and N2, so arranged that when the
valve or cut off is closed the said springs are put out of contact with the rod L and
the current is switched off.
The end of the rod L abuts against a spring N¼ which is secured to the plate N³,
the spring gives a slight return action to the said rod.
The batteries are coupled in series in the usual way, and the positive wire W is
carried to the rod L, and secured by means of terminal L³, and then to the
bridges or uprights P, and from there to the electro-magnets N. The positive
wire from the electro-magnets N is also connected to one of the pillars or
uprights D, by terminal D. The negative wire X from the battery is connected
to the other pillar or upright D, and secured by terminal D¹, both the said pillars
or uprights are provided with screws S so that the contact with the suspended
cross piece B can be regulated as required. The weighing apparatus or scales is
placed upon the table T.
The action is as follows:-
When the requisite weight of material has been obtained the scale pan A
carrying such, descends and the suspended cross piece B comes in contact with the
uprights, rods or pillars D, thus completing the circuit and thereby operating the
electro-magnets N which actuate the pivotted lever or rod M whereby the slide or
cut off is made to close the funnel, spout, or tube J, which can be again opened
by pushing the slide or cut off back by hand or otherwise.
The funnel or spout J is constructed with a tapering or narrowed passage V as
shown in Fig. 3, for regulating the flow or descent of the material.
For obtaining the necessary balance I employ a weight secured on the weight
pan, and which is suitably balanced to weigh four pounds, when so secured, and
for weighing two pound bags, I use a balance piece equal to about two pounds such
as shown in Fig. 5.
In the case of conical shaped bags I use a balance piece, such as shown in
Fig. 4, which is provided with a cup for receiving the bags and is equal to about
three pounds.
When weighing smaller quantities corresponding regulating weights are placed
upon the goods end of the scale, to give the requisite balance and raise the bag so
as to equalize their positions according to the length of same, so that the distance
from the cut off to the goods in the bag is the same in all cases.
When the electro-magnet has shut off the valve it shuts off its connection with
the battery and so prevents waste.

page_text: 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 :-
1. The method of weighing granulated sugar and other suitable substances or
materials such as shown and described.
2. For weighing granulated sugar and other suitable substances or materials
the construction of apparatus such as shown and described.
3. The construction of funnel for regulating the flow of the material such as
shown and described.
4. In apparatus for the purposes set forth the employment of a suspended cross
piece such as B free to slide on its suspenders, operating as and for the purposes
substantially as shown and described.
