STAPLING MACHINE
Harold s. Heller, Cleveland Heights, Ohio
Application June 25, 1942, Serial No. 448,359
7 Claims.
1
This invention relates to stapling machines,
and more particularly to the small portable type
known as oi‘l‘ce staplers. Such devices not only
should be small, of light weight, inexpensive and
yet sturdy and strong, but also should be free of
unnecessarily complicated mechanism, require
minimum care and attention, and present an
ornamental and pleasing appearance in so far
as that is possible.
One object of the invention, therefore, is to
provide an improved stapler which is sturdy and
strong though of relatively light weight; which is
of simple construction including a minimum
number of moving or operating parts so arranged
as not likely to get out of order in service; which
houses or encloses practically all of the smaller
working parts within other operating parts,
thereby not only protecting the mechanism from

A further object of the invention is to simplify

not to mar or injure it. As shown, these feet,

the staple carrying beam or magazine 2. This
consists of an outer casing member 25, made of
sheet metal in channel form with one end open
and the other end closed by a cross wall 25, as
shown in Fig. '6. It serves not only as a. support but
also as an enclosure for'other parts. These other
parts: include the magazine in which the staples
to be operated upon are contained. Said mag

lying outside of or embracing the corresponding
walls of the casing 25, as in Fig. 5. At one end it
is pierced and provided with bearing portions 4?
to receive the pivot pin l9 upon which it also
swings. At its; opposite end, as shown in Fig. 4,
it is closed by a front cross wall 48 and is pro
