U.S. Patent No. 2,940,637.
The invention illustrated and described herein relates
to apparatus for dispensing cleats to wirebound box-mak
ing machines of the type disclosed in United States Patent
No. 2,304,510, issued December 8, 1942.
In such machines, properly assembled cleats and side

material or slats are conveyed beneath a transverse bank
of stapling mechanisms where they are stapled to longi-v
tudinally extending binding wires to form wirebound box
parts or complete wirebound box blanks. The cleats
and other box part materials are conveyed through the
(FIGURES 2 and 3) which is secured to the rear face
of the member 164. As may be seen in FIGURE 2,
these aligned surfaces serve as alower support for the

column of cleats in the hoper.
Attached to the bracket 110 and extending horizontally
outward therefrom is a skeletal framework, bestV shown
in FIGURE 4 and comprising bars 112 and 114, which
supports a solenoid 116. The armature 118 of this
solenoid 116 is pivotally connected by short link members

mounted on bolts 124 >threaded into bracket 110. These
arms are normally maintained in a retracted position,
