FIELD OF ACTION OF THE INVENTION
This invention refers to a novel combined
perforator which also incorporates a stapler and staple
remover, and therefore its field of action is restricted to
normal file operations in an office or in the home.
Despite the above, the principles of this
invention can be used in other fields of industry or
commerce which requires perforating other types of materials
than a sheet of paper, in which case, the dimensions and
construction materials of the perforator, reason for this
invention, will be modified in such a way as to comply with
and satisfy the specifications, and consequently this will
not mean a restriction on its use, but rather on the
contrary, a possible wider application of the invention.
BACKGROUND OF THE INVENTION
As is known, to develop mainly file activities in
an office, it is necessary to perforate the sheets
frequently, and different systems have been developed from
box archives to the more conventional of joining them via
clasps or fastening posts with the paper sheets previously
perforated. Perforators are norma7.ly used with two
piercings in each sheet toward the left margin, or toward
the upper part. However, depending on the means of_
fastening, three or four piercings in the sheets may be
used.

As will be understood in solving the problems of
many piercings, different types or models of perforators
have been developed f.or the number of perforations.
Thus, in this case, the user has to purchase both
a two-hole perforator and a three-hole one, which becomes an
additional expenditure for the user.
These inconveniences can be eliminated with the
incorporation of a perforation system like the one proposed
for this invention, which has the advantage either of
incorporating a conventional stapler in such a way as to
form a single article or piece, particularly if designed for
perforating one, two, three or more piercings in a simple
form, with distribution of an equal distance between all the
perforations, adjusted to the conventional dimensions of
those correlative to clasps, folder rings or the file
elements to be used. Finally, by using this system, the
distance between the margin and the piercing is always the
same, which is very advantageous, since in this way all the
perforated sheets will coincide.
On the other hand, it is also necessary to do the
sheet stapling and staple removing operation. For the first
operation there is a large number of models. The
fundamental differences in the staplers consist in the
manner of loading the staples in an appropriate deposit in
the form of a cartridge holder so that they are used as
necessary. At the same time, these are found on the market

in different sizes for satisfying all the needs of users,
although some have the inconvenience of being closed at the
end part of the stapling, and if a staple becomes stuck, it
is difficult to examine and in the end repair.
SCOPE OF THE INVENTION
This invention refers to a novel desk perforator
or hole-punch combined with a stapler and staple remover and
its embodiment, which can be coupled to a desk stapler,
whereby a versatile office article is achieved with several
functions. Further, the perforation system presented has
been designed with registers or terminals for piercing or
perforating pages with one, two, three or more perforations
which results in an additional benefit for the user. It has
an attachment to be used as a staple remover or as a letter
opener whereby the functions are united in a single artefact
of perforating with several piercings, stapling, removing
staples and opening letters.
This invention comprises the combination of
several elements, which can be summed up by being formed by
a base with appropriate dimensions over which is mounted the
reinforced office perforated, composed of a cartridge where
the staples are lodged and which can be loaded or examined
by removing the cover, with a compression spring designed
appropriately whereby the staples are compressed smoothly
and uniformly, an impact sleeve or button which then

activated staples, a seat or base for the folding of the
staples with two positions, and if it is desired to staple
articles with greater dimensions, the whole body can be
turned over by removing a pin; a perforator consisting in a
punch element mounted on a small structure and united to the
base of the perforator with an impact button for activation,
also comprising some registers or terminals for indicating
the number of perforations on the stapler base; a flat
letter opener which due to the hewing on the sides can be
used appropriately to remove staples in a simple manner,
which is kept in the posterior part of the stapler
cartridge; a deposit toward the lower part of the stapler
base for keeping or collecting the perforated paper.
As a variation of this invention we present an
independent base on which is mounted the sheet punch element
and the perforation registers or terminals and the deposit
for collected perforated paper with the characteristic of
comprising appropriate fastening elements to be joined to
the base of a conventional perforator, and in this way have
a stapler and perforator. Lastly, all these fastening
elements can be eliminated in such a way as for the
perforator to be used independently when the user so
requires.

DESCRIPTION OF THE DISCOVERY
This invention refers to a novel desk perforator
for piercing paper sheets with one, two, three or more
piercings which is incorporated to a stapler and with a
stapler remover in such a way to have a single piece.
The characteristic details of the invention are
seen more clearly with the following drawings, which serve
as reference signs for denoting the details.
Figure 1 is a side view, snowing the whole of the
perforator, with the stapler integrated.
Figure 2 is another front view of the same
perforator and stapler.
Figure 3 gives a. conventional perspective of the
same perforator together with the stapler.
Figure 4 represents a conventional view of only
the perforator together with its fastening elements for a

system.
In reference to these figures, this invention is
formed by a base (10) in a rectangular form with appropriate
dimensions and materials for supporting normal treatment in
an office, with the characteristic of being able to bend its
edges downward, forming a small register box. On the base
(10) a stapler (20) is offset to one side, formed by a
cartridge holder (21} where the staples are lodged or

.I..i. . ,
placed, which are pushed by the whole of a channel and
spring. The spring is designed in appropriate dimensions
and materials in order to exercise uniform force. An impact
button (22) duly reinforced to support the force exercised
by the blow at the time of stapling is installed above the
cartridge holder (21). The body of the stapler (20) is
fastened through a small groove (23) and a bolt (24) as well
as a spring (25). A plate for bending the staples (26) has
two positions, which move via movement of the plate (26)
toward the front and vice versa.
Attached to the groove (23) of the stapler is a
small structure (31) which has toward its interior a shaft
(32) which forms the punch element of the perforator, and
having toward the upper end, an impact button (33), duly
reinforced and downward, a hewn point (34) for appropriate
perforation of the sheets. Toward the inside of the
structure (31), the shaft (32) comprising a spring (35),
duly adjusted and joined to the shaft (32) with which it
maintains an upward position of this shaft. Toward the ends
of the groove (23) there are some markings (36) as
references for the piercing of two or three-hole sheets.
Toward the side of the base of the stapler (10)
there are some perforation terminals or registers (37) with
indications for two or three perforations, in a cylindrical
form and raised with appropriate size and dimensions to
receive those paper sheets which are already perforated, and

in this way have the security that the perforated sheets
wi 11 have the sarr,e di stance.
In order to receive and keep the perforated waste
paper, there is a receiving tray (40) which covers all the
edge of the base (19),
As an embodiment of this invention, there is an
extension of the stapler base (10-11) with some fastening
and pressure elements (20-2) for joining a conventional
stapler (20-1) and in this way convert it into a single desk
article with the versatility of having a multiple
perforator.
Lastly, in order to remove the staples and open
letters, there is a flat lancet (50) with its edges cut back
and ending in a point to be introduced between the staple
and the paper and in this way remove the staple. It is
incorporated and placed toward an end of, the stapler (29).
As for its operation, it is the most simple, as it
is sufficient to follow the following rules: if it is
desired to perforate a sheet with two holes, the page is
marked half-way and this mark is put at the right end where
the number two is marked of the support plate (36); the
sheet is pierced by pressing the impact button (33); the
perforated sheet is brought toward the left until it is
coincident with the hole with the opening marked with number
two (37) in order to again do the perforating operation. If
three perforations are to be made, the left end of the sheet
7 _
1'. r; fa "~.; '~ ~'~
is made to coincide with the left end of the support plate
(36) where it is marked with number three; the sheet is
pierced by pressing the button (33); the sheet is moved to
the left until the piercing coincides with the opening
marked with number three (37); the button or knob (33) is
again pressed; the sheet is again moved toward the left
until the second hole of the sheet coincides again with the
opening with number three (37); the perforating operation is
done again. Preferably the lancet (50) is received in a
sliding fit manner in the stapler body (20), above the
spring (25) and bolt (24), so as not to interfere with the
normal operation of the stapler (29).
~9hile the invention has been described with
reference to preferred embodiments, it is not so limited.
Many modifications and variations wi21 now occur to persons
skilled in the art. For a definition of the invention,
reference is made to the appended claims.
