I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,
M.I.M.E. do hereby declare the nature of this invention to be as follows:-
-
The present invention relates to improvements in machines for corrugating paper or
the like for packing purposes.
Two sets of working blades are pivotted around a spindle, supported by a con-
venient frame, to a collar fastened thereon, one set above the other. These blades are
pivotted to toggles the other ends of the upper set of which are pivotted to the outer
end of a flange of an inverted dish sliding on the said spindle and the other ends of
the lower set being pivotted close round the spindle to a lower sliding dish. In this
manner the two sets of working blades will open and shut like umbrella frames when
the dishes to which they are pivotted are moved up and down on the spindle. When
the sliding dishes are raised to a certain extent the two sets of working blades will
stand horizontally extended one a little above the other. It is in this position that the
paper or other material to be corrugated is introduced between the two sets of working
blades which when the dishes are lowered will shut in and the blades of the upper set
will intercalate between the blades of the lower set and thus corrugate the paper pre-
viously placed between them. The upper or inverted dish and the covering cap of the
lower dish are formed with slots serving as guides for the toggles and these slots are
not radial but are tangential to the spindle so that one side of the corrugation shall be
deeper than the other. The dishes are moved on the spindle by any convenient
means.

In the accompanying drawings Fig. 1 is a vertical section and fig. 2 a side
elevation of a machine constructed according to this invention, figs. 3 and 4 are plans
of the dishes K and L respectively, fig. 5 is a plan of the underside of a piece of paper
corrugated by the machine.
Two sets of working blades c d are pivotted around a spindle formed in two
parts B B supported by a convenient frame A to collars a a¹ fastened thereon, one set
above the other. These blades are pivotted to toggles e d¹ the other ends of the upper
set of which are pivotted to the outer end of a flange C of an inverted dish K sliding on
the upper part B of the said spindle and the other ends of the lower set being pivotted
at D close round the part B of the spindle to a lower sliding dish L. In this manner
the two sets of working blades will open and shut like umbrella frames when the
dishes to which they are pivotted are moved up and down on the spindle. When
the sliding dishes are raised to a certain extent the two sets of working blades will
stand horizontally extended one a little above the other see fig. 2. It is in this
position that the paper or other material to be corrugated is introduced between
the two sets of working blades which when the dishes are lowered will shut in and
the blades of the upper set will intercalate with the blades of the lower set and thus
corrugate the paper previously placed between them. The upper or inverted dish and
the covering cap of the lower dish are formed with slots k and 7 serving as guides for
the toggles and these slots are not radial but are tangential to the spindle so that one
side of the corrugation shall be deeper than the other. The dishes are moved on the
spindle by any convenient means the upper dish preferably by means of the lever e
and the lower one by hand or by a second lever which may be operated by a pedal.

page_text: Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is :-
A machine for corrugating paper or the like comprising two sets of working blades
such as c d the blades e being pivotted at one end to a collar a fixed on the spindle
while the other end is pivotted to toggles c pivotted to a dish OK sliding on the
spindle the blades d being pivotted to a collar a fixed on the spindle at one end while
the other end is pivotted to toggles'd' pivotted to a dish DL, both sets of blades being
moved tangentially to the spindle the toggles being guided in tangential slots of the
sliding dishes so that the blades intercalate and corrugate the material placed between
substantially as described and illustrated in the accompanying drawings.
