Improvements in or relating to Corrugating, Shearing, Punching,
and similar Machines.
We, JOSHUA BIGWOOD, THEODORE CHARLES BIGWOOD and HENRY MALCOLM
BIGWOOD, trading together as J. Bigwood & Sons, of Tempest Street and Vane
Street, Wolverhampton, Staffordshire, Engineers, do hereby declare the nature of this
invention to be as follows:-
The first part of this invention has reference more particularly to that class of
corrugating machines in which a horizontal beam carrying the upper die is moved up
and down above a bottom corrugating die fixed to the bed of the machine; the said
moving beam being guided by end standards and receiving motion from a revolving
shaft underneath by means of cranks or eccentrics on the said shaft connected by
connecting rods to a joint screw at each end of the moving beam.
The said joint screws are usually connected to the moving beam by passing through
a vertical hole therein, the regulating nut or nuts on the screw being located in a
transverse slot or recess. This method of construction renders it difficult to remove
the joint screw when required for repairs or other purposes which defect it is one of
the objects of this invention to overcome. This we effect by providing a movable cap
or caps at each end of the beam above and below the adjusting nut or nuts these caps
being by preference semicircular inside to fit against the joint screw and secured to
the ends of the beam by bolts screws or other means so that the joint screws can
readily be removed or replaced by first removing the said caps.
Another part of this invention has reference to the construction of the crank shaft
bearings and the end standards of the said corrugating machines our objects being to
facilitate the removal of the crank shaft when required for repairs or otherwise.
According to this part of our invention instead of casting the crank shaft bearings
integral with the bottom beam of the machine we make them separate therefrom and
bolt or otherwise secure them to the underside of the beam or frame which carries the
bottom die and we make the lower parts of the standards separate from the upper
parts and bolt or otherwise secure the said two parts of the standards together, so
that, by first removing the said lower parts (the upper parts meanwhile being
securely held up by remaining standards) the crank shaft can readily be withdrawn
at the front or at the back of the machine without disturbing any other part of the
frame.
The parts of our invention above and hereinafter described can be similarly applied
to shearing punching and similar machines which are of similar construction and
provided with similar moving parts.
Another part of our invention has reference to the holding down bolts and to the
holding down plates which are built in the brick or other foundations of the said
machines, our object being to enable the holding down bolts to be removed at the top
of the foundations without the necessity of excavating to gain access to their lower
ends as is usually done. In carrying out this part of our invention the holding down
bolts which we use with the said plates are made with T-ends and each of the
foundation plates is provided with an oblong hole through which the T-end of the
bolt will pass. The said foundation plate is also by preference strengthened by
having a boss around the said hole on the upper side of the plate. Below the said
oblong hole in the foundation plate is a recess large enough to take the T-end of the
bolt when placed at about right angles to the oblong hole. When the foundation
plate above described is built in the brick or other foundation the T-end of the
foundation bolt is passed down the hole in the brick or other foundation and through'
the oblong hole in the plate; the said bolt is then turned round for about a quarter of

page_text: a revolution, in the same direction as the nut would be turned in screwing up, when
the T-end of the bolt will come into contact with a projecting stop or stops in the
said recess and prevent the bolt turning further the bolt being secured to the
foundation plate by its T-end engaging underneath the oblong hole. To remove
the bolt from the foundation plate it is only necessary to turn the bolt through
about a quarter of a revolution to allow of its T-end passing up through the oblong
hole.
Another of our improvements is devised to enable the plummer block forming the
end bearing of the crank or eccentric shaft and the bolts which connect the plummer
block to its sill plate to be removed without disturbing the shaft or the foundation
bolts or sill plate. This we effect by employing T-headed bolts for securing the
plummer block to its sill plate these bolts taking into end slots in the ends of the
plummer block and in the sill plate is a T-slot for each bolt the flat part of the T
extending beyond the ends of the plummer block. When the plummer block is in
place on the sill plate the bolts can readily be removed by slackening the nut and
then moving the bolt endwise out of the end slot in the plummer block when its
T-head will pass up through the flat part of the Ṭ hole in the sill plate.

COMPLETE SPECIFICATION.
Improvements in or relating to Corrugating, Shearing, Punching,
and similar Machines.
We, JOSHUA BIGWOOD, THEODORE CHARLES BIGWOOD and HENRY MALCOLM
BIGWOOD, trading together as J. Bigwood & Sons, of Tempest Street and Vane Street,
Wolverhampton, Staffordshire, Engineers, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This invention has reference to improvements in corrugating shearing punching
and similar machines of that class in which a horizontal beam carrying the upper die
or other tool is moved up and down above the bed of the machine to which the bottom
corrugating die or other tool is fixed; the said moving beam being guided by end
standards and receiving motion from a revolving shaft underneath by means of cranks
or eccentrics on the said shaft which are connected by connecting rods to a joint screw
at each end of the moving beam.
We will describe our invention as applied to a corrugating machine and in order
that the invention may be the better understood we will refer to the accompanying.
sheets of drawings on which Fig. 1 is a front elevation of part of a corrugating
machine embodying our improvements; Fig. 2 is a plan of part of the same; Fig. 3
is a cross section on line x x of Fig. 1 so as to shew the centre bearing of the crank
or eccentric shaft; Fig. 4 is an end elevation of the said machine; Figs. 5, 6 and 7
illustrate a part of our invention which applies to the end bearing of the crank or
eccentric shaft and its sill plate of the said machines, and Figs. 8, 9 & 10 illustrate the
part of our invention which applies to the foundation bolts and plates for the said
machines.
The same letters of reference indicate the same or corresponding parts in all the
Figures of the drawings.
A is the moving horizontal beam carrying the upper die B¹ and guided by the end
standards CC2 which are secured to the bed D of the machine by bolts d. The
moving beam A receives an up and down motion from the crank or eccentric shaft E
by means of connecting rods (not shewn on the drawing) which are jointed to the
usual joint screws F in the usual manner these joint screws being secured to the end
of the moving beam A. The bed D carries the bottom corrugating die B².
The joint screws F, F, are usually connected to the moving beam A by passing

page_text: through vertical holes therein, a regulating nut or nuts G on the screw being located
in a transverse slot or recess. This method of construction renders it difficult to
remove the joint screw when required for repairs or other purposes which defect it is
one of the objects of this invention to overcome.. This we effect by providing a
movable cap or caps marked a at each end of the beam A above and below the
adjusting nut or nuts G these caps a being by preference semicircular inside (see Fig. 2)
to fit against the joint screw and secured to the ends of the beam A by bolts a¹
or by screws or other means so that the joint screws F can readily be removed
or replaced by first removing the caps a.
Another part of this invention has reference to the construction of the crank or
eccentric shaft bearings marked H1, H2, H3, and the end standards C¹, C², of the
said machines, our objects being to facilitate the removal of the crank or eccentric
shaft when required for repairs or otherwise. According to this part of our inven-
tion instead of casting the crank shaft bearings H1, H2, H³, integral with. the
bottom beam D of the machine, as is usual, we make them separate therefrom
and bolt or otherwise secure them to the underside of the beam or bed D, and we
make the lower parts c¹, c¹, of the standards separate from the upper parts c², c², and
bolt or otherwise secure the parts c¹, cl, to the parts c², c², so that, by first removing
the lower parts (the upper parts c2 which were bolted to the removed lower
parts meanwhile being securely held up by being suitably propped and by the
remaining standards) the crank or eccentric shaft E, and its bearings E¹, E², È³, (if
required) can readily be withdrawn at the front or at the back of the machine without
disturbing any other part of the frame.
Another part of our invention has reference to the holding-down bolts and to the
holding-down plates which are built in the brick or other foundations of the said
machines our object being to enable the holding-down bolts to be removed at the top
of the foundations without the necessity of excavating to gain access to their lower
ends as is usually done. In carrying out this part of our invention, which is
illustrated in plan by Fig. 8 and sectional elevations by Figs. 9 and 10, the holding-
down bolts I which we use with the said holding-down plates (marked J) are made
with T-ends i and each of the foundation plates J is provided with an oblong hole j₁
through which the T-end i of the bolt I will pass. The holding-down plate J is also
by preference strengthened by having a boss around the hole j¹ on the upper side
of the plate. Below the oblong hole j' is a recess j³ large enough to take the T-end i
of the bolt I when placed at about right angles to the oblong hole j¹. When the
foundation plate J is built in the brick or other foundation the end i of the foundation
bolt is passed down the hole in the brick or other foundation and through the oblong
hole in the plate; the bolt I is then turned round for about a quarter of a revolution,
in the same direction as the nut would be turned in screwing up, when the T-end i
of the bolt will come into contact with a projecting stop or stops j* in the recess³
(see Fig. 8) and prevent the bolt turning further, the bolt being secured to the
foundation plate J by its T-end i engaging underneath the oblong hole j. To remove
the bolt I from the foundation plate J it is only necessary to turn the bolt through
about a quarter of a revolution to allow of its T-end i passing up through the oblong
hole j¹.
Another of our improvements (which is illustrated by Figs. 5, 6 and 7) is devised
to enable the plummer block K forming the end bearing of the crank or eccentric
shaft E, and the bolts which connect this plummer block to its sill plate M, to be
removed without disturbing the shaft E or the foundation bolts or sill plate M. This
we effect by employing T-headed bolts for securing the plummer block K to the sill
plate M, which bolts 112 take into end slots k¹k in the ends of the plummer block,
and in the sill plate M is an inverted T-slot m for each of the bolts 112 the flat part
of the T extending beyond the ends of the plummer block K. When the plummer
block is in place on the sill plate (see Figs. 5 and 6) the bolts 11 12 can readily be
removed by slackening their nuts and then moving the bolts end wise out of the end
slots k¹² in the plummer block when their T-heads will pass up through the flat parts
of the T-holes in the sill plate.
