Stokes and Smith Company, Summerdale, Phil
adelphia, Pa., a, corporation of Pennsylvania
Application May 17, 1937, Serial No. 143,012
28 Claims. (Cl. 93-542)
My invention relates to apparatus for covering
Fig. 12 is a timing chart referred to in descrip-.
previously formed or stayed boxes by applying tion of the operation of the machine;
thereto sheet material, such as a wrapper, label
Figs. 13 to 19, in perspective, illustrate the
or the like, or for forming a box from a single
5 or multi-piece blank by applying thereto sheet
Referring to Fig. 1, at station No. 1, the form
tabs solely, to hold the box elements in box
block F is attached to the lower end of a plunger
I from which extends a stud 2 connected by link
3 to a lever 4 pivotally connected at 5 to the
frame member 6 of the machine. The rod 7 10
pivotally connected at its upper end to lever 4
is connected at its lower end to lever 8 (Fig. 6)
In accordance with my invention, the appa
ratus comprises two reciprocating form blocks
with which there are associated respectively tools
for performing supplemental sheet-applying op
erations, and for each cycle of the machine a
carriage reciprocates in a path intercepting the
15' paths of the form blocks to transfer partially
formed or wrapped box structure stripped from
one of them into the path of the other for sup
plemental sheet-applying operations; more spe
ci?cally, upon the carriage are mounted corner
20 lap folding tools which move toward each other
to perform a corner-lap folding operation when
the carriage is in, or approaches, its box-receiving
position in the path of one of the form blocks,
and which are moved away from each other as
the carriage moves to that position; more spe
ci?cally, the carriage serves to eject from the
machine the completed box stripped from the
other of the form blocks.
My invention further resides in the features of

For an understanding of my invention, and
illustration of a preferred form thereof, refer
ence is to be had to the accompanying drawings,
‘ in which:
Fig. 1 is a side elevational view, with parts in
section and parts omitted, of a box machine;
Fig. 2 is a rear elevational view, with parts
omitted and parts in section, of the machine
40 shown in Fig. 1;
Figs. 3 and 4 are detail views, on enlarged
scale, illustrating modi?cations of form block
structure shown in Fig. 1;
Figs. 5 and 6 are top plan views of parts appear
45 ing in Fig. 1; >
Figs. 7, 8 and 9 illustrate, on enlarged scale,
the transfer carriage shown in Fig. 1 in various
projecting from the housing 9 at the base of the
machine. The lever 8 is pivoted to a stationary
member within the housing 9 and is provided
with a cam follower for engaging the peripheral
groove II (Fig. 1) of a cam l2 which makes one
revolution for each cycle of the machine. Cam
I2 is driven from the motor l3 by pulley l4, belt
,
I5, and driving member l6 of a one-time clutch 20
ll whose driven member I8 is secured to shaft
I9. The worm In (Fig. 6) on shaft l9 drives
the gear 20 on the same shaft as gear 20a which
is in mesh with the gear 21 secured to the cam
12 or its shaft.

after the caption “No. 1 main”, the form block
F does not descend immediately upon beginning
of the machine cycle but, on the contrary, re
mains in its “up” or box-receiving position for a
prolonged period facilitating disposition thereon 35
of a box structure, for example, a box or box
blank B to which is adherent a partially applied
wrapper W, such as shown in Fig. 13. The wrap
pers may be tabbed as indicated by tabs t; or
the wrapper may be omitted, in which event the
tabs are of the type shown in Stokes U. S. Patent
#1326264, Fig. 11.
The length and width of the form block F
correspond to the inside dimensions of the box
to be made, but the depth of the form block may
be suitably large to accommodate a range of
boxes of the same length and width but of dif
operating positions;
ferent depths.
Figs. ‘7a, 8a and 9a are plan views showing var
ious positions of tools appearing in Figs. 7, 8
As the form block F moves downwardly from
the position shown in full lines in Fig. 1, it meets
the lower form or platen P to clamp the box
structure or assembly between the two form‘
blocks F and P.
The platen P is disposed on the upper end of
a plunger 22 guided by the tubular member 23 55

10. At this time, the movement of the carriage has
so far progressed that the box holders’ ‘I9 are
in engagement with one end of the box B on
form F, and the box holders 82 are in engagement
with the left-hand end of the box (Figs. 8, 8a).
15 The members 19, ‘I9, 82, 82 are so shaped that
in moving to the box-holding position, they turn
the flaps f, Fig. 14, extending from the side pan
els of the wrapper beyond the ends of the box
into adhesive engagement with the ends of the
20 box, Fig. 15; speci?cally, each of the members
?9—82 is provided with one face 94 for engaging
the side wall of the box adjacent the corner, and
with a face 95 at right angles thereto which en~
gages a projecting ?ap f of a wrapper side panel
25 and wipes it into engagement with the box end
(Fig. 15).
After this corner-lap operation has been per
formed by the box~holding members or corner-lap .
the faces of the block and are in communication
with the hollow member Ia, which may be the
main plunger. Pump I02, Figs. 1 and 2, driven
by motor I3, supplies the suction; the aforesaid
Rider application illustrates valve mechanism
which may be used for controlling or timing the
application of suction; in brief, suction is cutoff
after the corner-lap operation or before stripping
of the box from form F and is re-established at
or about the time the ascending form block F 10
reaches the rolls 44. When the box walls are of
height insufficient to cover the upper ports, these
ports may be temporarily plugged to avoid loss
of suction, as indicated inv Fig. 3.
Use of the suction type form block permits the 15
operator to place an assembly-“stayed box, box
blank, or component of a blank, and adhering
sheet material—on the form block at any time
during its period of accessibility and then im
mediately to be free to- prepare the next assembly. 20
This period begins approximately when the form
F’ in ascending clears the brushes 45 and con
tinues until the form in descending is so close to
platen P abox cannot be inserted between forms
F and P.
