This invention relates to a sheet attaching
mechanism, applicable more particularly to sta
pling machines of conventional form embodying
a relatively movable anvil and head for securing
a staple through a plurality of sheets, and it has
for its purpose to provide a construction that will
enable attaching two or more sheets together by
scription when read in conjunction with the ac
companying drawing, the novel features being
pointed out in the claims following the speci?ca
tion.

In the drawing:

which occupiesonly the extreme corner portion
ing a modi?ed form of the invention;
Fig. 4 is a side elevation of the construction
of the sheets.
The usual practice in stapling a multiplicity of
paper or other sheets together is to attach the
staple parallel to and spaced from one edge, and
where the staple is attached at one corner, it
penetrates the sheets and is frequently located
a substantial distance from the edges so that if
it later becomes necessary to separate the sheets,
the staple must ?rst be removed by bending back
its ends with a suitable instrument, or else the

sheets must be defaced by tearing them apart, 25 of the invention in fastening a sheet to the sur
and one object of the invention is to afford a
structure that enables fastening together a multi
plicity of sheets by means of a staple located at
the extreme corner of the sheets so that the staple
can be easily and quickly removed with the ?n
gers by exerting the tension required to overcome
the frictional engagement between the staple and
the adjacent surfaces of the sheets, a sheet can
be torn off along the line of the staple by de
stroying only a small corner portion of the sheet,
or a sheet can be pulled out from the rest with
out destroying or seriously defacing it.
The invention makes it possible to use staples
as temporary or frictional retaining devices for
holding together a multiplicity of sheets and thus
to take the place of the conventional paper clips
or other similar fastening elements and effect a
considerable saving in cost, while affording ine
strumentalities which hold a multiplicity of sheets
together with sufficient tightness to function sat
face of a larger sheet.
The invention is useful and of particular ad
vantage wherever it is desirable to attach to
gether two or more sheets of paper or other ma
terial and hold them in any attached relation as
long as desired, while permitting quick'removal
of the fastening means if necessary or the re
moval of a sheet by tearing it at the corner along
the staple where attached, or by removing it
against the frictional resistance of the staple. and
instances of such uses are found in attaching a
check, price list, folder, return card, or other
sheet to a remittance blank, statement, letter, or
advertising vbroadside respectively, also the fas;
tening of a smaller sheet on to a larger sheet in
spaced relation to its edges as in affixing mer
chandise on display boards, and while the inven
tion is susceptible of use with conventional sta
ples of standard size, it is preferable to employ
isfactorily as a permanent fastener, but permit
ting easy removal of the fastener or separation of
a somewhat longer staple, for instance about
three-quarters of an inch or more in length, so'
