The invention illustrated and described herein relates
to machines for manufacturing wirebound box and crate
blanks and particularly to machines for automatically at
taching the box ends to such blanks.
U.S. Patent No. 2,772,700 discloses a machine for at
taching ends to wirebound box blanks, in which the box
blank, after being delivered from the loop fastener ma
chine, was automatically rotated to place its cleated side
up and presented to a pair of transversely spaced stations
incorporating box end attaching mechanisms. Although
most of the end attaching operation was performed auto~
matically, there still remained the necessity of having a
person at each box end attaching station manually posi
tion the box ends before they could be secured to the box
blank.
The machine embodying the present invention per
forms all of its operations automatically and is designed
to cooperate with wirebound box manufacturing machines
of the type disclosed in United States Patents No. 2,161,
200 and No. 2,304,510, to complete the ?naltoperation
of a continuous production line in the manufacturing of 60
wirebound box blanks, by‘ automatically inserting and at

The general, construction of the present machine is
shown in FIGURES l, 2 and 5. As may be seen in these
FIGURES, the machine includes an open bed frame 2
with supporting legs 4, a pair of spaced, longitudinal rails
6 and 8 to support and guide the work, a rubber tired
infeed wheel 10, a rubber tired stabilizing wheel 12, an
auxiliary conveyor M which moves the Work within the
machine, a pair of loop fastener bendingunits T1 and T2
spaced apart longitudinally of the machine and mounted
at opposite sides of the frame 2, and a pair of box-end
conveying units ‘01 and 02 for conveying box ends thereto.

outwardly a sufficient distance toward the loop fastener
machine U to receive box blanks thereon as they are fed
from said machine (FIGURES 1 and 2). As may be
seen in FIGURES 5, 8 and 9, the rails 6 and 8 have
secured to the upper portion of their inner faces angle

mounting of the two assemblies permits infeed wheel 10
,to ride up and onto an incoming box blank while its
weight and that of the associated assemblies impose suf~
?cient downward pressure on the box blank to drive it
at the same speed as that at which it is delivered by the
loop fastener machine U.
To stabilize the box blank as it is being fed up the

of said bolt and interposed between the undersurface of
bracket 68 and the head of bolt 66 allows the receiving
end of auxiliary conveyor M to yield upwardly as the box
blank arrives beneath it.
As shown in FIGURES 1, 2, 6 and 7, the active con 60
veying element of the conveyor M is a rubber belt 72,
which is trained about a pulley ‘74 rotatably supported on
a bolt 76 carried by the right-hand end of the depending
?ange 78 of angle member 62, and about a pulley 80 of
much larger diameter which is ?xed on a sleeve 82 rotat
ably supported on a stationary shaft 84. As shown in
FIGURE 2, the inner end of the shaft 84 is supported
in a block 86 mounted on the upper surface of the left
hand end of angle member 62, while its outer end is sup
shown in FIGURE 2, this switch H being actuated by
the leading edge of a box blank, as indicated by broken
lines W, when the box blank has been moved within the
machine by the auxiliary conveyor M to the point where
it contacts a spring ?nger 166, causing a stud 168 threaded
therethrough to actuate the plunger of the switch H. The
switch H and the spring ?nger 166 are mounted on a
bracket 170 adjustably attached to the lower portion of
rail 6.
As may be seen in FIGURE 12, the switch H is a nor
mally open, single-pole, single-throw switch, which is
closed when the spring ?nger 166 (FIGURE 2) is en
gaged by the leading edge of the box blank and which,
ported in a block 94 secured at the upper face of an

for a sufficient length of time to have attached thereto,
in the illustrative example, a pair of box ends 0 of the
type shown in FIGURE 13, each having stapled to one
of its faces two spaced binding wires whose ends are bent
to form loop fasteners 03. As shown in FIGURE 14,
the fasteners 03 are inserted through notches 190 in the
cleats 180 and 18% of the box blank, and are bent around
in its vertical movement by a bar 134 which projects up

hingedly to the box blank.
As may be seen in FIGURE 7, the outer face of the
left-hand rail 6 has formed in it a shallow vertical groove
128 which serves as a slideway for a wedge-shaped lo
cator 130. As may be seen in FIGURES 3 and 4, a
similar wedge-shaped locator 132 is mounted at the outer

As may be seen at the upper left in FIGURE 12, the
switch F is a single-pole, double-throw switch which is
normally in the position shown in full lines. When it
is actuated by the engagement of the leading edge of a
box blank with the lever 150 (FIGURE 2), it is thrown
to the position shown in broken lines, energizing a sole
noid valve 1,. As may be seen at the bottom of FIG
URE 7, the solenoid valve J1 controls the supply of com
pressed air from the line 171 to an air cylinder 172
fastened to an arm 174 extending from an upstanding
post 176 mounted on frame 2. When the solenoid valve
I1 is energized, compressed air is supplied to the cylinder
172, driving its piston upwardly, and forcing the wedge
justably suspended a gear motor 202. The motor 202
imparts counterclockwise rotation to a shaft 204 whose
intermediate portion is rotatably supported in a bearing
206 (FIGURE 10) through the medium of a belt 208
trained about the drive pulley 210 of motor 2%2 and
about a pulley 212 keyed to the shaft 204.
The box ends 0 are fed lengthwise of the unit by a

260 and 262 actuate electric switches R1 and R2 which
are fastened to an arm 264 projecting laterally from the
aforementioned vertical post 176 mounted on the frame

Upon the actuation of switch R1, two operations occur
substantially simultaneously: the box blank sections which

by broken lines Z in FIGURE 8, to serve as a guide to
direct the loop fastener 03 on the box end 0 beneath
the binding wire Y of the box section and into the notches
