A New or Improved Machine or Apparatus to be used in Making
up for Sale Packets of Tea, Coffee, Sugar, and other like
Substances.
:
We, EDMUND KERSHAW and WILFRED WILLIAM KERSHAW, both of Lockwood's
Yard, New Street, Huddersfield, Yorkshire, Tea Merchants, do hereby declare the
nature of this invention to be as follows :-
This invention relates to a new or improved machine or apparatus to be used in the
making up, for sale, of packets of tea, sugar, and other like substances which are
capable of being made up into packets, the object of our invention being to lessen
the hand labour at present required in making up such packets, by substituting
mechanical means to perform portions of the work, by reason of which a saving of
time is effected and a better made packet produced.
In order to carry out our invention, we employ a series of plates or leaves, hinged
to each other side by side, and capable of being folded upon an ordinary hollow block
used in making packets by hand. These plates are operated so as to surround the
said hollow block by means of suitable levers or fingers, one of which is rather longer
than the other, working through slots or openings made in the table or stand sup-
porting my improvements, such levers or fingers being raised by means of a foot
treadle and caused to descend by a spring or weights, or the weighted end of the said
treadle. One of the central plates is hinged at one end to the table, so that when
required the plates may be stood on end. One of the end plates is covered or coated
with gum or other suitable mucilage, and a sheet of paper, or tin or lead foil, of the
required size, is then placed over the series of plates. Onto the paper and directly
over the central plate hinged to the table is placed the hollow block, and on motion
being given to the levers or fingers by operating the treadle with the foot, the afore-
said plates are folded over or caused to surround or nearly surround the hollow block,
and the paper being thus confined between the said plates and the block, assumes the
shape of a packet. By reason of the action of the longer finger upon the end plate
supplied with mucilage, the said plate is forced down onto the upper surface of the
hollow block, and the paper confined thereunder is then taken hold of or held down
by one of the opposite plates, whereupon the first named plate is released and with-
drawn out of the way by means of a spring. The mucilage on the aforesaid plate
having adhered to the surface of the paper in contact therewith, it follows that when
the opposite edge of the paper is pressed down thereon the two surfaces will adhere
or stick together. The end plates are now closed down upon each other and the whole
secured by a lever, rod, or catch, thus forming a second hollow block surrounding the
inner one.
One end of the packet is folded by hand in the ordinary way, and the
plates and hollow block afterwards turned up onto one end so that the open end of
the packet and the enlarged or funnel end of the hollow block are at the top; into
the hollow block is now emptied the weight of tea or other substance to be packed,
which is pressed down, the hollow block withdrawn, and the end of the packet made
up in the usual way, after which the plates are turned down, opened out, and the filled
packet removed.
Suitable stop pieces are employed to determine the movement of the plates in one
direction and gauges or stop pieces or both may be employed so that the hollow block
and the paper may be readily placed in the correct position.
Different sizes of machines are employed for different sizes of packets to be made.

A New or Improved Machine or Apparatus to be used in Making
up for Sale Packets of Tea, Coffee, Sugar, and other like
Substances.
We, EDMUND KERSHAW and WILFRED WILLIAM KERSHAW, both of Lockwoods
Yard, New Street, Huddersfield, Yorkshire, Tea Merchants, 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:―
This invention relates to a new or improved machine or apparatus to be used in
the making-up, for sale, of packets of tea, sugar, and other like substances which are
capable of being made up into packets, the object of our invention being to lessen,
the hand labour at present required in making up such packets, by substituting
mechanical means to perform portions of the work, by reason of which a saving of
time is effected and a better made packet produced.
In order to carry out our invention, we employ a series of plates or leaves, hinged
to each other side by side, and capable of being folded upon an ordinary hollow block
used in making packets by hand. These plates are operated so as to surround the
said hollow block, by means of suitable levers or fingers, one of which is rather
longer than the other, working through slots or openings made in the table or stand
supporting our improvements, such levers or fingers being raised by means of a
foot treadle and caused to descend by a spring or weights, or the weighted end of
the said treadle. One of the central plates is hinged at one end to the table, so that
when required the plates may be stood on end. The paper to be folded is placed
directly over the central plate hinged to the table, and the hollow block is fastened
in position, and when motion is given to the levers or fingers, the aforesaid plates
are folded over or caused to surround or nearly surround the hollow block and the
paper being thus confined between the said plates and the block, assumes the shape
of a packet.
Such being the nature and object of our invention, we will now proceed to
describe the same more fully, and for that purpose make reference to the accompanying
sheets of drawings illustrative thereof, wherein
Fig. 1 is sectional elevation of our improved apparatus ;
Fig. 2 is plan view thereof, and
Fig. 3 is plan view shewing the several parts closed.
The two first figures illustrate the position occupied by the mechanism when about
to commence forming the packet. B is the table on which the packing is performed,
supported by suitable framework C. The plates to fold the paper are shewn at a, b, c,
d, e, f, hinged to each other as shewn in the drawings. D represents a hollow packing
block around which the paper is folded, as hereinafter described. This block is
placed upon the central plate c, the paper to be folded being previously laid flat
upon the said plates. The operator presses his foot upon the treadle E, causing the
vertical rods G and H to rise, in doing which the rod G, which it will be observed
is longer than the rod H, comes into contact with plate b, forcing it up against the
left hand side of the packing block as shewn in dotted lines Fig. 1, the same upward
movement of rod G also causing the outer leaf a to be forced onto the upper surface
of the packing block. Simultaneously with the operation of the two plates a and b,
just mentioned, the remaining three plates de f, are also raised by the upward
movement of rod H, and placed into the position shewn in dotted lines of Fig. 1.
On the continued upward movement of rod G the angle shaped piece g is drawn by
the elastic or other form of spring h through the slot in the vertical rod G, shewn
more clearly in Fig. 6, causing the piece g to occupy the position shewn in dotted
lines in Fig. 4, permitting platef to fall into the place vacated by the said plate a,
such movement being effected by the continued upward motion of vertical rod H,
which being shorter in length than rod G, acts later. In the upward movement of
rod H the shoulder J, shewn more clearly in Fig. 6, comes into contact with the

page_text: hinged finger i attached to the back of plate e which places the plate ƒ in proper
position upon the hollow block C, as shewn in full line Fig. 4; afterwards the
operator with his hands turns down the plate a onto the plate f, making both secure
by the catchy on the end of finger i. The projecting ends of the bottom of the paper
packet are then folded in by hand as shewn at k in Figs. 4 and 9, when the whole
of the apparatus is raised into a vertical position as shewn at Fig. 5, which is section
through line A A in Fig. 4, the central plate c being hinged to the table to permit
of this being done.
The modus operandi is as follows:-When first commencing to fold paper into a
packet, it is placed as shewn in dotted lines at Fig. 2 upon the several hinged folding
plates, the right hand edge of said paper being pasted, by the operator, who then
actuates the treadle, causing rods G and H to rise so as to make the several plates
perform the operation already described, folding the paper into the condition shewn
in Fig. 7, leaving the gummed or pasted part 7 in an upright position, as shewn at
Fig. 7, but when the angle plate g has been thrown by the spring / through the
slot I on the upper end of rod G, the part f, which is later in its movement, follows
on and closes the gummed part on to the top of the folded paper as shewn in Fig. 8.
When this is done, the apparatus is raised as shewn at Fig. 5, and the tea or other
substance is placed into the funnel of the block C, which is afterwards withdrawn
from the folded paper, and the top or open end thereof closed in the ordinary manner,
as shewn at Fig. 9. An elastic band or spring m connected to the brackets m² m²
is employed to hold the plate in an upright position until the plate a is raised out
of the way as previously described; and other elastic bands or spiral springs n and n¹
are also employed to draw back the finger i and plates f, e, after the catch has been
released for the purpose of allowing the completed packet to be removed, and the
several plates to be placed in position for making another packet. p is a can
containing the paste or mucilage which is put on to the paper by means of a small
brush.
By the employment of the apparatus herein shewn and described, sheets of paper
can be expeditiously and neatly folded for the reception of tea, sugar, or other
substances.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The machine or apparatus comprising hinged leaves or plates for closing upon a
block in manner and for purposes substantially as herein shewn and described.
