Improvements in or relating to Straw. Board Lining Machines.
A communication from ARNOLD W. SCHLICHT, of 93 and 95, Sixth Avenue,
New York, County and State of New York, United States of America,
Manufacturer.
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 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 the construction of a machine designed to line or face
sheets of cardboard with any style of white or coloured paper and the invention
consists essentially of one form of mechanism by the use of which the operator is
able to sever the web which constitutes the lining material between each sheet of
board after the lining material has been pasted and pressed upon the board the
parts being so arranged that sheets of board of varying size may be used without
in any way changing the adjustment of the machine, and of another form of
mechanism by which the severing of the web is automatically effected and the
invention further relates to a longitudinally expanding roller by which the longi-
tudinal wrinkles may be removed from the moistened or pasted web of paper or
lining material.
In the accompanying drawings in which similar letters of reference indicate
corresponding parts:

One of the greatest difficulties encountered in lining straw-board is due to the
fact that the boards are far from being of uniform size or shape and secondly most
of the machines constructed to sever the web between the sheets are necessarily

made so that there will be quite a space between the boards as they are fed into
the rollers and consequently quite a loss of paper as well as an additional amount
of work due to the trimming up of the sheets after they have left the machine.
With this improved form of lining machine however the sheets may be introduced
so that there is very little space between their meeting edges and one having been
severed the lining sheet requires no further manipulation.
In constructing the machine there is provided a paste trough A in which there
is arranged a paste distributing roller a and directly above this paste roller a there
is a guiding roller 6 other guiding rollers as c being arranged in any convenient
position for a purpose hereinafter explained. The pressure rollers de are arranged
directly in front of the feed table B and just beyond these pressure rollers there
is a loosely constructed frame C in which there is mounted a second frame D
carrying a severing knife E preferably formed with a serrated edge as shown,
although any form of knife that would sever the web would answer the purpose.
The frame D is guided by the longitudinal cross strips of the frame C and
also by the extending ends of its lower cross strips g which project outward from
each side of the frame D to ride against the faces of the vertical strips h. The
frame C is pivotally connected to the brackets fixed to the floor of the apartment
in which the machine is located; or the brackets to which the frame is connected
may be carried by any appropriate framework.
The frame D is normally held in the position shown in Figure 2 by spiral
springs i one end of said springs being secured to the frame C while the other ends
are secured to the frame D or to pins projecting therefrom.
To the lower bar g is secured the cord which passes downward over the sheave¹
and then upward toward the right of the machine over a guiding sheave k¹ and is
finally secured to a lever F Fig. 1 that is mounted to swing upon the pivot G and
it will be seen that by throwing the lever in the direction of the arrow y the frame D
will be pulled down to the position shown in Figure 3.
As best shown in Figure 4 the central cross bar of the frame D is formed with
two recesses or notches and in these recesses are arranged the upper ends of the
upper links m of two or more toggle levers M M the lower links m' of which are
pivotally connected to the lower cross bar f of the frame C the central joint of
the toggle levers being connected by a connecting link N. Upon the forward face
of the lower cross bar f I arrange a guiding sheave o and over this sheave o is
passed a cord p one end of which is fixed to the rod N while the other end is
secured to the lower cross bar g of the frame D. The upper ends of the links m
carry stops & which project upward just in front of the severing knife E. The
second cord 9 is fixed to the rod or link N and is passed over the sheaver carried
by the frame C and is carried backward to a fixed point q'. The frame C is
normally held up close against the rollers de by the action of a weight H which is
connected to the frame by means of a cord & which passes over a sheave a¹ as
shown in Figure 1.
The machine is preferably driven by a crank arm or equivalent connected to the
shaft of the roller & the paste roller a being in turn driven by appropriate connecting
gearing.
The web of paper L with which the sheets of straw-board are to be lined is
taken from a roller K mounted in any convenient position and is carried downward
beneath the guiding roller b which runs in close contact with the paste distributing
roller a by which paste is distributed upon the face of the web L. The web is
then carried to the guide rollers c which act to thoroughly distribute the paste upon
the surface of the web and from the guide rollers c the web is carried around the
roller d and into the bite of the rollers de the roller e being held in yielding contact
with the roller d. After the web is in the bite of the rollers d and e the sheets of
cardboard may be fed in from the table B and after being carried forward will
strike against the stops s Figure 2 and thus carry the frames CD forward in the
direction of the arrow z.
As soon as the frame is in this manner carried forward
the attendant grasps the lever F and pulls it toward him in the direction of the

page_text: arrow y so as to draw down the frame C to the position shown in Figure 3 thus
severing the web; but as the frame C is drawn down the cord p is also drawn down
and the toggle levers carrying the stops are moved to the position shown in
Figure 3 thus permitting the leading end of the sheet to pass forward beyond the
stops and over guides to the guide rollers t from which rollers the sheets are taken
and piled by hand. Immediately after moving the lever F to depress the knife E
the attendant releases the lever and the weight H raises the frames C and D until
they are near the rollers d and e and as the frames so move back the cord q will
draw the toggle levers to the position shown in Figure 2.
From the construction described it will be seen that immediately upon the
release of the lever F the frame D will return to its elevated position and thus
raise the end of the sheet which has become somewhat depressed in the operation
of severing the web so that the said end will not catch against the upper horizontal
strip of the frame and it will be seen that this return of the frame D takes place
before the stops s are returned to their raised position.
a certain
In order that the operation of the machine need not be interrupted if the
attendant should fail to pull the lever F in time to draw down the stops s there is
secured to the connecting link N a second cord u which is passed about the sheave v
and carried forward to a fixed point beneath the feed table there being
amount of slack in the cord which is not taken up until after the swinging frames
have passed the position to which they would ordinarily be moved. In order that
the knife E may be closed after each operation there is arranged a strip v¹ carried
by the frame C close up against the face of the knife.
As before stated the frame C is loosely put together the idea being to permit a
certain amount of yielding of the frame at either side, should the strip of board be
uneven so that the stops upon one side are met before those on the other side come
in contact with the leading edge of the board.
In the arrangement shown in Figures 5 to 8 which are drawn to a larger scale
than Figures 1 to 4 the knife frame D is drawn down by a rock shaft R having
arms R that are connected to the frame D by links R'. The shaft R also carries
an arm R³ to which is connected the rod or link R' that extends to a short crank
or arm R' loose upon the shaft S that is mounted in bearings formed in a bracket S¹
Figure 8 secured to the main frame of the machine. The shaft S carries a fixed
disc S having a catch S Figure 6 and an inwardly extending stud or projection S
to which is connected a spring S³ that is secured to any fixed object as for instance
the machine frame.
To the bracket S¹ is pivotally connected a lever T the upper end of which is
connected to the frame C by a rod T' which passes through the lever and carries a
stop T
This lever T carries an adjustable stop T against which stop the
catch Sabuts as will be presently explained, the lever being held against the
disc S2 by a spring T or the lever may be held to the disc in any other convenient
way.
In addition to the parts above referred to, the shaft S carries a fixed disc U
having one or more notches or recesses U₁ in its peripheral edge and upon the shaft
here is loosely mounted a chain wheel U' which carries one, two, three, four or
nore pivotally supported and laterally extending dogs or pawls U³. Four dogs are
hown in the drawings.
The wheel U is driven by a chain U which runs upon a wheel U³ that is carried
y the shaft of the feed roller d.
Motion may be imparted to the roller d in any desired manner as for instance by
means of a crank handle U that controls the gear wheel U which engages the
heel U secured on the shaft of the roller d.
From the above description it will be seen that if the crank handle U³ be
urned in a direction proper to advance the roller d that is to say the direction
dicated by the arrow in Figure 5 the chain U will be moved to advance the
heel.U. It will be remembered that the discs S and U are fast upon the
aft S and from the construction illustrated in the drawings it will be seen

page_text: that the tendency of the spring S is to hold the shaft S and the parts controlled
thereby one half turn in advance of the position in which said parts are shown
in the drawings that is to say in a position such that the recesses U1 of the
disc U will be above the shaft. When the disc U¹ is in the position just
referred to it follows that as the wheel U is advanced, one of the pawls or
dogs U will drop into one of the recesses U¹ and the shaft S will be moved
forward against the tension of the spring S' until the stud or projection S* is
carried just past the centre when the spring S will act to carry the parts slightly
forward with a quicker motion than that imparted by the drive chain this quicker
forward motion however being checked by the catch S3 striking against the stop T.
As the motion just described takes place the pawl U³ will drop from engagement
with the disc U and all parts will be held as represented in the drawings the
arm R³ at this time rising on the pin or projection U that is carried by the disc U.
If now the leading end of a sheet of board strikes the frame C so as to move
it slightly forward the stop T' will be carried from engagement with the catch S³
and the spring S will then be free to carry the shaft S forward and as the shaft S
is moved forward the rock shaft R will be turned and the frame D drawn down to
carry the severing knife E through the web.
The above described movement is repeated as each sheet of board passes through
the machine.
Referring to Figures 9 to 13 V represents a roller supported at either end by a
pintle or centre pin V₁ the point of which enters a socket formed in a casting V'
secured to the appropriate end of the roller body, the pintles being adjustable
by means of jam nuts V³ arranged upon either side of the frame as illustrated.
Each end of the roller V is slightly cut away and in these cut-away portions
are formed grooves V with which engage L-shaped projections W which extend
inward from the plates W arranged around these two reduced ends of the roller V.
As many of these plates W as may be necessary to enclose the roller are applied
at each end. In the drawings the roller is illustrated as being provided with three
plates W.
The plates W extend beyond the ends of the roller V. and to the inner faces of
these outwardly extending portions there are secured studs, projections or anti-
friction rollers W2 which enter cam grooves X that are formed in castings which
are secured to the frame of the machine in connection with which the roller is to be
employed; all the castings in which the cam grooves are formed might be made
integral with the frame. The cam grooves extend gradually outward from the
point until they reach the point when they are carried in abruptly to the point
so that as the roller is moved in the direction of the arrow v Fig. 1 the plates W
will be carried outward in the direction of the arrows w as the roller V advances but
will be carried inward to their original position when the studs W* enter the abrupt
portion of the cam groove X between the points ¹ and x.
The last described rollers will be found exceedingly useful for conducting the
pasted webs through the before described straw-board lining machine for, as the
webs pass over the roller constructed as above described, each plate W will move
gradually toward the ends of the roller V during the time that the paper is in
contact therewith, the plates W being returned to their inner position after they
reach the point where they are no longer in contact with the web the acute portion
of the cam groove being located so as to bring about this return movement at the
time when the plates are not borne upon by the paper.
As the webs are passed over the last described rollers the plates W will act
to expand all longitudinal wrinkles so that the web may be delivered for association
with the straw board sheets in a perfectly smooth condition. Although a particular
means for holding the plates W to the roller V has been described it will of course
be understood that other means may be employed without departing from the spirit
of the invention.
In Figure 13 is illustrated a cam ridge instead of a groove and in this case the
plates are forced back to their inner position by an inclined cam Y.
