Application June 21, 1945, Serial No. 600,661
17 Claims. (Cl. 164-91)
The invention relates to improvements in mul~
tiple perforating devices and more particularly
to a device of the kind having a plurality of ad
justably positioned punch heads, including
punches, adapted for selective operative associa
tion with manually actuable punch operating
means.
The perforating device of the character dis~
closed herein is particularly adapted for punch
ing holes in sheet material, such as sheets of
paper, to facilitate the binding of such sheets
with fasteners or like means in ?les 0r binders.
Fasteners of a kind commonly used to, bind sheets
in a ?le usually are furnished in a plurality of
sizes; that. is, the fasteners are formed with
prongs or like elements, spaced apart at different
distances to be extended through holes punched
in the sheets. Other kinds of ?le folders, such as

with a plurality of punches each embodying a
novel construction adopting it to be selectively lo
cated for operative engagement by a common ac
tuating element.
Another object of the invention is to provide a
perforating apparatus in which the perforating
elements include means movable into and out of
effective position for selective operative engage
ment by actuating means associated therewith.
Another object of the invention is to provide a
device of the character described which is not
expensive to manufacture and which is very effi
cient in use and easy to manipulate.
Other and further objects of the present inven
tion will be apparent from the following descrip
tion and claims and are illustrated in the accom
