Improvements in the Manufacture of Cell Cases or Fittings for Crates
or Boxes used for the Transit of Eggs, Fruit and the like.
I, GEORGE WILLIAM SWIFT, Jr., of Bordentown, in the State of New Jersey,
Mechanical Engineer, 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; -
My invention relates to the manufacture of cell cases or "fillers" for crates
used in the transportation of fruit, eggs, etc., one of its objects being to provide
simple and efficient mechanism, to automatically produce from flat paper webs,
a continuous fabric comprising rectangular cells.
My invention comprises not only improvements in the construction and opera-
tion of mechanism of the class described, but also comprehends a peculiar forma-
tion of the partition strips of the fabric aforesaid, which conduces to a more
efficient and rapid automatic manufacture of cell cases by said mechanism
than has hitherto been possible.
My invention comprises a machine to which are supplied separate flat webs
of paper from which are respectively formed the longitudinal and transverse
partition strips of the cell cases. One of said webs of paper being first perforated
with a series of similar slots, extending transversely of said web in a curved
line: said web is then divided into a plurality of longitudinal strips, the
arrangement of said slots being such as to provide each of said longitudinal
strips with similar notches for engagement with the transverse strips, subse-
quently inserted therein by the automatic action of the machine.
Subsequent to said longitudinal division of the aforesaid paper web each of
its strips is turned at right angles with the plane of the web, by separate feed
rollers which assemble the strips with their slots or notches in straight aline-
ment. Said rollers feed said assembled strips to mechanism which bends the
edges of said notches to insure their proper engagement with the transverse
strips.
The web from which the transverse strips are to be formed, is passed between
feed rollers to suitable mechanism and perforated with a series of slots arranged
transversely with respect to said web, in a straight line. The edges of said slots
are then bent to facilitate engagement thereof with the notches in the longitu-
dinal strips. Said web is then fed into engagement with the longitudinal strips,
with the notches of which said transverse web is in registry. A strip, of width
equal to the longitudinal strips with which said web is engaged, is then cut
transversely from said web, and passes thence as a portion of the cell case
fabric.
The aforesaid operation is of course repeated at intervals, determined by the
dimensions of the individual cells, the transverse strips being thus successively
inserted in proper relation with the longitudinal strips, a continuous fabric of
cell cases is formed which is fed forward in the machine by the feeding mecha-
nism engaged with the continuous longitudinal strips of the first named paper
web, and thus presented in proper relation with shearing mechanism which

page_text: separates said fabric into blocks or fillers containing a predetermined number of
cells.
Said shearing mechanism comprises opposed blades, each provided with knife
edged notches, equal in number to the said longitudinal strips in the cell case
fabric. Said blades being reciprocated at predetermined intervals so that the
respective notches of said blades engage with the respective longitudinal strips
of said fabric, said blades are relatively shifted when in proper relation with
said strips so as to simultaneously sever said strips, and thus form the separate
blocks of cells, or fillers, as aforesaid.
During the engagement of the shearing mechanism with the fabric, the latter
is held in proper relation therewith by means of mechanism which also ensures
that the transverse strips are seated in proper relation with the longitudinal
strips.

In said figs., A, A', are the side frames of the machine, connected by stay
rods a.
A2, is a table at the front of the machine serving to support the paper
web X, which ultimately forms the longitudinal strips in the cell case fabric Z.
A³, is a table which supports the paper web Y, which ultimately forms the trans-
verse strips in the cell case fabric Z. A, is the table which supports the cell
case fabric. Each of said tables is fixed with respect to the side frames A, A¹,
aforesaid.
B is the main driving shaft provided with tight and loose pulleys B', and B2,
respectively, and a fly wheel B. The gear wheel B+, which is fixed upon said
shaft B, serves to connect the latter with the cam shaft C, by engagement with
the gear wheel C, fixedly mounted thereon. The cams upon said shaft serve to
operate various devices comprised in the machine, but I shall first describe the
punching dies which effect the initial operation of perforating the paper web X,
in the manner shown in Fig. 21.
It may be seen by reference to said Fig. 21, that each row of perforations
extending transversely of the web X, is arranged in a curved line. A single
row of said perforations is made at each stroke of the die cross head D, shown
in section in Fig. 3, and in detail in Figs. 4, and 5, said cross head is provided
with individual male dies d, conveniently secured therein by screws d¹. Said
dies register with corresponding female dies which are similarly secured in the
cross bar D¹, extending between the side frames A, A¹, in fixed relation therewith.
A chute D, is conveniently disposed in fixed relation with said cross bar to
deliver the waste paper from beneath the latter, exterior to the machine.
The plane faced extremities 12, 12, of said cross head I), are adapted for longi-
tudinal reciprocation in the frame slide ways A5; said cross head being suit-
ably adjusted therein by means of the cheek pieces d², screws ³, etc. Said cross
head is provided at each extremity with a cylindrical extension D3, upon which
are journalled the rods D, which connect the cross head 1), with the eccentrics D³,
mounted upon the cam shaft C. The rotation of said shaft of course serves to
reciprocate said cross head to effect said punching action of the dies above
described.
The paper web X, is fed forward upon the table A2, beneath the cross head D,
by means of the opposed rollers E, E; respectively mounted upon the shafts E2,
3. As shown in Fig. 15, each of said rollers is provided with a shearing or
slitting blade E, said rollers being placed seriatim upon their respective shafts,
are oppositely disposed in the two series so as to adapt them for co-operative
shearing action. The upper left hand roller E, and the lower right hand
roller ¹, are each provided with an extra shearing blade e, to properly co-
operate with the shearing blade E*, opposed thereto.
Fig. 18, is a central vertical section of the aforesaid end roller E¹, showing
the attachment of the respective shearing blades E, and e*, thereon, by means
of countersunk screws e. Such a construction is of obvious advantage in facili-
tating the restoration of worn shearing blades, each of the rollers aforesaid being
rotatively fixed upon its respective shaft by means of its key seat c², and pre-
vented from lateral movement by set screws c³.
Said shafts E2, and E3, are respectively provided with intermeshed gears E,
and E, to insure their simultaneous rotation. It is obvious that the extent of
the rotary movement of said rollers which occurs between the operative strokes
of the cross head 1),.determines the longitudinal distance between the perforations
of the web X.
The machine which I have shown is provided with seven pairs of rollers E, E,
and is therefore adapted to divide the web X, into seven strips to form the cell
case fabric Z, which is six cells wide. It is desirable for convenient handling

page_text: .
.
of the cell case fabric, to separate it into blocks or fillers six cells long, thus con-
taining thirty-six cells.
In order that said fillers may be separated from the cell case fabric without
waste, it is desirable to have a diminished interval in the feeding action, between
the successive series of seven equidistant rows of perforations made by the a
dies d, etc., to receive the transverse strips. Said diminished interval ¹, may
conveniently be one-half the extent of the normal intervals ., of said series, as
shown in Figs. 21, and 24.
To effect the aforesaid irregular intermittent rotation of the shafts E, and E³,
etc., I resort to the device best shown in Fig. 16. The hand wheel E, fixed on
the shaft 3, facilitates the introduction of the paper web X, between the rol-
lers E, and E¹. The ratchet wheel E, provided with thirteen equally spaced
teeth, is also fixed upon said shaft and the pawl disk E8, is loosely mounted
thereon between said hand wheel E, and said ratchet E7.
Oscillatory motion is imparted to said pawl disk by means of the rod E⁹, which
connects said disk with the rocker arm M', hereinafter described. The throw
of said arm M, and the consequent movement of said disk E8, is such as to
normally rotate the shaft E, the extent of two teeth at each reciprocation, but
the cam e, mounted upon the shaft E3, in fixed relation with the ratchet wheel E7,
serves to lift the pawles, after six normal strokes; the relation of the parts being
such as to cause said pawl to rotate said shaft the extent of but one tooth, instead
of the normal extent of two teeth.
In Fig. 16, the pawl 8, is shown in position upon the cam c', the forward
position of said pawl being indicated by the dotted lines in said fig. It is obvious
that said cam prevents the seating of the pawl in engagement with the proximal
tooth of the ratchet; causing it to ride over said tooth and engage with the
next in the manner indicated, thus diminishing the feeding stroke as aforesaid.
In the initial manipulation of the machine to insert the paper web, etc., it is
desirable to place said pawl es, in idle position so as to leave the shaft E3, free
for rotation by means of the hand wheel E6, I have therefore provided means
to secure said pawl in such position, at the will of the operator. As illustrated
in Fig. 17, the disk Es, is provided with a conical headed spring detent E⁰,
adapted for engagement with a socket el, in the side of the pawles. The
weight e, upon the extremity of said pawl e8, is conveniently knob shaped to
. facilitate the manipulation of the latter. It is of course obvious that as said
pawl is drawn outward by the operator, the detent E10, recedes until it is free
to engage in the socket elo, from which it may be withdrawn by reverse move-
ment of the pawl by the operator.
As shown in Fig. 21, the seven longitudinal strips X', extend from the
rolls E, E, (indicated by a dot and dash line in said fig.) in twisted form to the
seven pairs of vertical feed rollers F, F, which assemble said strips in position
to receive the transverse strips Y'.
The extent of the respective strips from one set of rolls to the other differs in
accordance with their convergence toward the central strip, therefore: if the
perforations in said web extended transversely thereof, in a straight line it is
obvious that by reason of their convergence aforesaid, the notches or perforations
in the outer strips, would fall behind a straight line extended transversely
through the notches of the center strip, at or beyond the line of the vertical
feeding rollers, so that it would be impossible to insert the transverse strips in
a straight line in the seven longitudinal strips. The perforations of said web X,
are therefore arranged as shown in Fig. 21, substantially in the arc of a circle,
so that the perforations in the outer strips are a sufficient distance in advance
of the perforations in the center strips to present in straight transverse registry
when converged as aforesaid.
The detailed construction of said feed rollers F, and F, is best shown in
Figs. 6, 7, and 8, wherein it appears that all of the feed rollers F, are provided with
heveled pinions f, upon their lower extremities, being mounted for rotation in

page_text: the housing F, which also serves to support the horizontal driving shaft F³,
upon which are fixed the beveled pinions f, in mesh with the pinions f.
The shaft F, is provided with a band wheel F³, connected with a similar band
wheel F, upon the main shaft B, by the belt F³.
The feed rollers F', are mounted for idle rotation upon shafts f'. In order
that said rollers may be adjusted in accordance with the thickness of paper
operated upon; said shafts f, are provided with eccentrically disposed cylindric
ends entered in suitable bearings in the housing F, and secured therein by set
screws f³. It is obvious that said rollers F₁, may be caused to approach or
recede from the rollers F, in accordance with the rotative adjustment of their
fixed shafts f¹.
To facilitate said adjustment, the upper extremities f, of said shafts f³, are
slotted to receive a screw driver and extend through the horizontal web of the
transverse frame member A, which serves to support the housing F.
The frame member A6, also serves to support the conduit G (indicated by the dot
and dash line G, in Fig. 21) through which the transverse strips are inserted.
Before describing said operation, and the means by which it is effected, I will
describe the operations which are preliminary thereto, in the formation of the
transverse strips Y', from the paper web Y.
The web Y, passes under the roller H, as shown in Figs. 1, 3, and 14, the
roll from which said web is unwound being arranged with respect to the machine
so that the convex side thereof is presented uppermost to said roller which tends
to remove its normal curl. Said roller is suspended in the yoke h, from bear-
ings in the opposed guide flanges I. The flanges I, are adjustable by means of
the slots and bolts indicated at i, in Figs. 1, and 14, serving to direct the passage
of the paper web Y, across the table A, in proper relation with the conduit G.
I prefer to use a presser block J, in conjunction with the roller H. Said
block has a plane lower face and is free for vertical and rotative movement upon
the gudgeons j, mounted in the side guides I. Said roller H, and block J, serve
to render the paper web Y, substantially flat before its introduction to the con-
duit G. It is obvious that the paper web X, may be similarly treated before
its introduction to the forming mechanism herein before described, but it is of
particular advantage to so treat the paper web Y, to facilitate its automatic
management as hereinafter described.
The web Y, is fed from the table A³, through the conduit G, by means of
opposed rollers K, K', mounted respectively upon the shafts K2, K³. The
shaft K³, is mounted in boxes ³, in the side frames A, A', respectively, being
adapted for adjustment toward and from the shaft K2, in slide ways A', and
being provided in the respective side frames with springs k', which cause the
rollers K, to impinge upon the web Y, inserted between said rollers and the
rollers K; the latter being positively driven as follows:-
The shaft K, is provided with a ratchet wheel K, fixed thereon. The pawl
disk K³, is loosely mounted upon said shaft K2, between said ratchet wheel K',
and the fixed collar Ko: the parts being so related that the pawl, pivoted upon
said disk K, is adapted to engage the teeth of said ratchet wheel K, and rotate
the shaft K2, the extent of one tooth at each reciprocation, thus intermittently
feeding the paper web Y, vertically downward in the conduit G. Said pawl
disk K, derives its motion of reciprocation from the wrist plate K7, upon the
shaft C, being connected therewith by the rod K³, shown in Figs. 1 and 2.
Referring now to Figs. 6, 7, and 8: The front wall g, of the conduit G, for
the web Y, is flush with the rear face of the series of female punching dies L,
the latter being fixed upon the transverse frame member A6. Suitable aper-
tures 1, are formed in said frame member in registry with the openings in said
dies, and a chamber 1, is formed toward the front of the machine behind said
dies by means of the casing a, wherein the waste paper punched from the
web Y, is received. Said chamber communicates with a chute L, as shown at
the left hand side of Fig. 6; the latter serving to deliver the waste paper from

page_text: said dies exterior of the machine. Said waste is discharged from the chamber 1,
by rotation of the spiral shaft L', which is mounted for rotation in the frame
member A, and provided with a band wheel L², upon its cylindrical extremity.
Rotary movement is communicated to the band wheel L2, from a similar band
wheel" L³, upon the shaft B,, by means of the belt L, best shown in Fig. 3.
The male dies M, which co-operate with the dies L, aforesaid, to perforate
the paper web Y, are mounted upon the cross head M, and conveniently secured
therein by screws m. The plane faced extremities M, M³, of said cross head
being mounted for longitudinal reciprocation in the frame slide ways As, said
cross head is provided with cylindrical studs m, upon which are journalled the
links M2, which are at their other extremities loosely mounted upon the trans-
verse shaft member M³, which rigidly connects the rocker arms M, the latter
being mounted for oscillation in the respective side frames A, A¹. The mem-
ber M³, extends through said rocker arms to receive the extremities of the
rods M³, M³, reciprocated by the respective eccentrics Mo, mounted upon the
shaft C.
Suitable apertures g*, are provided in the rear wall gl, of the conduit G, to
permit the operation of the punching dies M aforesaid, which perforate the
web Y, in the manner indicated in Fig. 22.
The feeding action of the rollers K, K', occurs in advance of the punching
action of the dies M, L, so that the forward edge of the web Y, which has the
configuration indicated at the left hand of Fig. 22, is thrust downward into
engagement with the seven longitudinal strips of the paper web X, and simul-
taneously with the punching action aforesaid, a transverse strip of the fabric Y,
is severed from it, by the shearing action of the blade N', which is fixedly
mounted upon the cross head M. Said blade co-operates with the ledger
blade N, fixed upon the frame member A To insure proper co-operation of
said two blades the blade N1, has a slightly downward set and is provided at
its forward edge with lateral projections n¹, rounded upon their lower corners
so as to ride over the blade N, and insure the proper alinement of the blade N¹,
therewith.
Owing to the peculiar interlocking form of my improved filler strips it is
necessary for their proper engagement that they should be prepared by opening
the respective notches which are to be engaged, before said engagement is effected,
this preparatory bending of the notched edges is best shown in Fig. 23, and is
effected as follows:-
•
As shown in Figs. 3, 9, and 10, the table A4, is provided with a series of mat-
rices 0, which are presented in the path of travel of the seven strips of the
paper web X, immediately adjoining the vertical rollers F, F¹. Said matrices
comprise opposed sheet metal plates, the upper rear corners of which are bent
as indicated at o, in Fig. 9, so that as said strips lie therein, the edges a², of
the notches a, of the respective strips X, are bent in the position indicated in
Fig. 23, said notches, being thus opened to receive the notched edge of the
paper web Y. The edges y², of. the notches y", in respective strips Y', of the latter
are bent as shown in said Fig. 23, by means of the frame P, which is mounted
for oscillation upon its upner shaft member P, in the bearings p, upon the
frame member A. The lower bar P, of said frame is provided with forming
plates adapted to bend the edges y, of said notches y³, over the corners 23,
of the rear wall gl, of the conduit G, and thus open said notches y³, for engage-
ment with the notched strips X', (see Fig. 23).
The bending action of the frame P, occurs upon the withdrawal of the male
dies M; as shown in Figs. 1, and 2; the normal position being that shown in
Figs. 7, and 8. The shaft P¹, in fixed relation with which the frame P, oscil-
lates, is provided as shown at the right side of Fig. 6, with a lever arm P', in
position to be rocked by the stud pt, fixed upon the pawl disk K³. The oppo-
site end of said shaft P₁, is provided with a lever arm P, the spring P³, connec-

page_text: tive of said arm, and the fixed pin p³, serving to return said oscillating frame P,
to normal position.
The various devices above described serve to complete the cell case fabric Z,
in the form shown in Fig. 24 it is obvious that as thus formed said fabric may
be discharged from the machine and its subdivision be subsequently effected by
separate mechanism, I prefer however, to provide mechanism which co-operates
in proper time with the other devices described, to 'shear said fabric inter-
mediate of the diminished intervals between the series of notches in the longi-
tudinal strips; before its discharge from the machine; as follows:
Referring to Figs. 1, 2, 3, and 9, Q, Q, are two shearing bars each provided
with a shearing blade g. Each of said blades is provided with seven knife
edged notches q¹, slightly inclined to the perpendicular, in reverse direction in
the respective blades. As indicated in Fig. 3, said shear bars Q, are mounted
together in yokes Q', being adapted for endwise movement therein upon rol-
lers q, said yokes Q', being mounted for vertical reciprocation in slide ways A",
upon the respective side frames A, A¹.
Each of said shear bars Q, is provided with a roller Q2, adapted to respectively
engage in the cam slots g², formed in fixed relation with said slide ways A.
As shown in Fig. 2, the configuration of said slots 2, is such as to respectively
and oppositely shift said two shearing bars Q, transversely of the fabric Z, at
the extremity of the upward stroke of the yokes Q', causing the respective knife
edges of the notches q¹, to overlap. Said notches q', being in line with the
respective longitudinal strips, it is obvious that the operation just described
serves to sever said strips.
In order to insure the proper co-operation of the knife edged notches in the
respective blades the latter are pressed into intimate contact by means of the
spring extensions 3, upon the bars Q, which normally have a slightly outward
set at their upper extremities, and bear against the parallel side pieces a³, of the
slide ways A³.
As aforesaid, the shearing operation is so timed with respect to the other
operations of the machine that the above described lifting of the yokes Q', and
consequent shifting of the shear bars Q, occurs when the diminished intervals
in the fabric Z, are in registry with said shearing blades y, said yokes being
vertically reciprocated as hereinafter described.
As shown in Figs. 1, 2, and 3: The plunger R, is mounted for vertical
reciprocation in the transverse frame member A10, which is supported at oppo-
site sides of the machine, upon the respective slide ways A8. Said plunger R,
is connected by a link R', with an arm, fixedly secured upon the shaft R*.
The arm R2, fixedly mounted upon the extremity of said shaft R*, projects
between the frame A, and the pawl disk K³, being encountered by the stud 2,
upon the latter, during its operative stroke, serves to positively thrust said
plunger R, downward. Reverse movement of said plunger is effected upon the
reverse movement of the pawl disk K³, by means of the spiral spring, which
encircles the stem of said plunger, and bears at its respective ends upon the frame
member A10, and the collar, fixed upon said stem.
Said plunger reciprocates simultaneously with the cross heads D, and M, etc.,
and is provided at its lower extremity with a plate head r, adapted to impinge
upon each of the transverse strips Y', as they are successively presented beneath
it by the step by step feeding movement of the fabric Z. Said head r, is grooved
as indicated at r¹, in registry with the longitudinal strips X¹, so as not to
impinge upon the latter; its downward thrust upon the transverse strips Y¹,
insuring the proper seating of the latter in said longitudinal strips.
Said plunger R, not only insures the proper seating of each transverse strip
in the fabric Z, but also serves to hold the fabric Z, down upon the table A³,
during the upward stroke of the yokes Q', and the transverse stroke of the
bars Q, which occurs as above described, at every seventh stroke of the plunger R.
The cam S, is fixedly mounted upon the shaft C, upon which the pitman S,

page_text: is mounted for reciprocation by means of its yoke S¹. Said pitman S, is pro-
vided with a roller s, entered in the cam ways, in said cam S. The motion of
reciprocation which is imparted to said pitman S, by the rotation of the cam S,
is communicated to the rocker arm S, which is loosely mounted upon the
shaft T; the latter being suitably journalled in the side frames A, A. Said
shaft T, is provided with two arms T, T¹, mounted in fixed relation thereon,
and said arms T¹, are connected with the respective yokes Q', by means of the
links T.
The sleeve T, which is provided with a clutch shaped end t*, opposed to a
similar clutch shaped hub, on the arm S3, is adapted for longitudinal move-
ment with respect to said shaft T, but rotatively secured thereon. Said sleeve
is provided with a circumferential groove t, in which are engaged the projec-
tions, upon the bifurcated extremity of the lever U; the latter being ful-
crummed at U, upon the transverse member of the frame A", and the stud u',
at the opposite extremity of said lever being entered in the circumferential
groove of the cam V*, fixed upon the shaft V.
The relation of the parts just described is such that although the pitman S,
and loose rocker arm, are reciprocated by rotation of the cam S*, in synch-
ronism with each reciprocatory movement of the cross heads D, and M, etc.,
said movement of reciprocation is not communicated from said arms S2, to the
shaft T, and the yokes Q¹, except at the proper intervals aforesaid; by the revolu-
tion of the cam V* fixed upon the shaft V.
The shaft V, is intermittently rotated in synchronism with the step by step
movement of the feed rollers E, E¹, by means of the link W, which connects
the pawl driving disk Es, with the similar disk W. Said disk W, being loosely
mounted upon said shaft V, between the collar e, and the ratchet wheel V (both
of which are fixed upon said shaft), engages and rotates said ratchet V₁, and
shaft V, in the manner aforesaid, by means of the pawl w, which is pivotally
mounted on said disk W, (see Fig. 1).
I do not desire to limit myself to the precise construction, which I have shown
and described, as it is obvious that various modifications may be made therein,
without departing from the spirit of my invention.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is
