Means and Apparatus for Wrapping or Folding and Creasing Sheets.
of Paper and other Material,
We, FRANCIS GEORGE FRICKER and JOHN THOMAS BIBBY, both of Little Pearl
Street, Spitalfields, Engineers, do hereby declare the nature of this invention to
be as follows::
-
This invention relates first to an expansible and contractable apparatus operable
by screw toggle or other means in order that sheets of paper or other material:
of different sizes can be wrapped or folded round it by the one apparatus instead
of employing separate standard sizes of machines as at present.
Secondly, the invention relates to swing plates which by cam or other motion
are caused to impinge against and in some cases to enter and force or form
creasing impressions on or to the paper or other material wrapped or folded round
the apparatus as mentioned in the first portion of this specification.
For the purposes of our invention we take, say, four square or other shape of
bars, wood, iron, or the like for hardness and stiffness, so as to form the four
corners of a flat square or a flat rectangular surface from the end. These bars
are in connection by screws and ferrules or by toggles on a screw shaft that they
can be set farther apart or be brought close together as desired, and be set in the
respective positions by lock nuts.
The screws and lock nuts can be affixed in filling in plates, or separate plates of
fixed widths can be slid in grooves of the edge bars, or otherwise fixed to fill up
the gaps
that would exist in order that the paper or other material when wrapped
or folded should be devoid of creases or other than those for inward accordeon
pleating which the swing plates or pleaters of the second part of this invention
have to produce. Said plates or pleaters by cam or other motion are then caused
to enter anglewise in the slits in that part of the expansible frame where the paper
or other material leaves the end of the first hereindescribed apparatus, when
pushed or slid off in a square or approximate shape.
The pleater plates are of plain sheet metal, mounted horizontally and eccentric-
ally on pillars, and these have toothed quadrants or cams geared into by racks
which cause the plates to move circularwise and approach and enter the side
walls of the folded or wrapped tube like sheet of paper, and press sufficiently far
as to form an accordeon like pleat as the tube is leaving the "former" on which
the tube has been produced.
The apparatus herein before described is applicable to and can be fitted in any
standard frame of machine used for folding and creasing paper and other
material.

of Paper and other Material.
We, FRANCIS GEORGE FRICKER and JOHN THOMAS BIBBY, both of Little Pearl
Street, Spitalfields, London, in the County of Middlesex, Engineers, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement and accompanying drawings:--
Our said invention relates generally to improved means for folding and creasing
sheets of paper in machinery or apparatus where such folding and creasing
is effected for some specific object, such for instance as the manufacture of paper
bags. As an example of such machinery we might refer to apparatus for making
paper bags for which a Patent No. 17658 of 1895 was granted to one of us the
said Francis George Fricker. The present invention might be usefully described
as constituting improvements upon the said previously patented apparatus
although not strictly confined thereto.
Our invention will be clearly understood from the following description when
read in conjunction with the annexed three sheets of drawings.
In the said drawings, on Sheet 1,
Figure 1 is a side view of an improved expansible and contractible former
constructed in accordance with our invention.
Figure 2, is a plan view of Figure 1.
Figure 3 is a sectional end elevation taken on the line X-X Figure 1.
On Sheet 2,
Figure 4, shows a portion of the former together with the right and left
side folders referred to in the said prior specification as the plunger.
Figure 5 is a plan view of the right and left folders.
Figure 6 is an end view of Figure 5.
Fig. 9 is a diagrammatic view of the bottom of a completed bag.
Fig. 10 shows a side and plan view of a partially finished bag as it leaves the
adjustable former.
On Sheet 3,
Figure 7 is a side elevation of the swing plates which impinge against the
partially finished bag as it leaves the former and force in its sides.
Figure 8 is a plan view of the swing plates and parts.
Referring first of all to the former shown on Sheet 1 of the drawings. In order
to allow of various sizes of bags being made on the same machine, we make the
former A so that it may be expanded or contracted, in width and vertical thick-
ness, whereby different sizes of tubes are produced as indicated in Figure 9.
To effect this the former is built up of four plates a, b, c, d, the plates b, c, d,
being adjustable towards and from each other and towards and from the main
body a.
Each of the movable plates b, c, d, carry guide spindles b c d which
guide the plate in a perfectly straight path when moved. To operate the parts, we
employ screws e e, f, f', the parts bd moving together or the parts c d, accord-
ingly as the sets of screws e el or f f are operated. The screws e, f, are formed
with reduced extensions which fit holes bored in the plates be so that when such
screws are revolved they effect the expansion of the parts, whilst the screws el fl
are formed with heads so that when operated they effect the contraction of the
parts. In other words, the screws e f effect the lifting or outward movement of
the plates bed and the screws e¹ f¹ carry in such plates. To expand or contract
с

page_text: the former, all the attendant needs to do is to operate each set of screws by means
of a suitable key either to the right or left.
The heads of the screws lie flush with the outer faces of the plates b c as is
clearly shown in the drawing.
By the use of the former above described various sizes of tubes are capable of
being produced on the same machine.
If thought desirable we may arrange to close the spaces which would at times
exist between the movable parts bed by means of plates or strips of varying
thicknesses so as to prevent any possibility of the formed tube being creased.
As the former is expanded or contracted so it is necessary that one blade of the
plunger shown on Sheet 2 of the drawings should be adjusted. In this case the
right hand blade h of the plunger 58 is capable of being moved in and out by
means of screws. The screws carry out the blade h whilst the screws h² take
it in the screws being operated practically in the same manner as described with
reference to the screws in the former A. The blade his guided in its inward and
outward movement by spindles h³.
To allow of the top of the former maintaining a constant level we propose to
raise or lower the former bodily and to permit of this being done the plunger 58
is adjustably carried in a bracket i.
To fold in the sides of the bag as it leaves the former, (see Sheet 3) we employ
swing plates or fingers o o' which force in the vertical sides of the bag and move
forward with it to the segmental rollers (129) between which the bag is
crushed as set forth in the earlier patent. By the use of the swing plates o o¹
we are enabled to bring about the collapse of the partially formed bag. The
swing plates or fingers oo¹ are adjustably attached to arms o2 by means of bolts o*
the arms o³ being secured to vertical shafts o supported in a footstep or bearing o¹.
The shaft o carriés a bevel wheel of which gears with a bevel wheel of carried
on a cross shaft of supported in suitable bearings. To the cross shaft of we
secure a lever 08 one end of the lever carrying a bowl o hearing in a cam
groove formed in the cam q fixed on the shaft 2. The revolution of the cam
acting through the lever os imparts a slight motion to the shaft o and conse-
quently to the bevel wheel of which acting through the bevel o³ causes the
plates oo to swing towards and from the bite of the segmental presser rollers ? p.
The outward or first position of the swing plates o o¹ is indicated in full lines
in Fig. 8 whilst their inward or second position is indicated in dotted lines.
It will be clearly understood that there are two sets of swing plates o o¹ to
each machine one on each side of the former and we have not thought it necessary
to show both sets fully in the plan view Fig. 8.
When the bag lies at the end of the tube, its formation has been so far com-
pleted as is indicated in Fig. 10; that is to say the top and bottom end folds have
been formed, the bottom pasted, and the wings * produced, such wings standing
out at right angles to the bottom of the partially formed bag. For one way of
effecting this partial formation of the bag bottom we may refer the reader to the
said prior patent. The right hand bottom wing of the bag bears against adjust-
able guides r as indicated in the plan view Fig. 8 the guide on the other side
being fixed if desired.
The pushers 127 described in the former specification now push the partially
formed paper bag beyond the end of the former whereupon the two sets of swing
plates o o force in the sides of the bag and move with it into the space formed by
the flat faces of the segmental rollers ? p (129). Arrived in this position the bag
now lies, with its bottom wings * projecting therefrom, almost against the flat
faces of the segmental rollers ? ? and the further folding operations are effected
bag and deliver the same in a finished state.
by the successive action of suitable parts so as to complete the formation of the
By means of our invention not only is the construction of the machine con-
siderably simplified but we are, by slight adjustments, enabled to construct
bags of various sizes on one and the same machine.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is: -
1) In machines for making square or oblong shaped bags from sheets of paper
constructing the former and plunger so as to be capable of expansion and con-
traction whereby different sizes of tubes are produced substantially as described
and shown.
2) In machines of the indicated nature, the improved construction of former and
plunger consisting of the adjustable plates b, c, d, and the adjustable blade h on
the former and plunger respectively operated by sunk screws and guided by
spindles, in the manner, and substantially as described with reference to Sheets 1
and 2 of the drawings.
3) In machines of the indicated nature forming the side creases in the bags by
means of adjustable swing plates which force in the sides of the bag as it
leaves the former, substantially as described with reference to Sheet 3 of the
drawings.
