5 Claims. (Cl. 282-—22)
This invention relates to a writing pad of that
type comprising alternate writing sheets and car
bon sheets, that is adapted for use in typewriters
and the like.
In the past, various methods have been used
for making such writing pads so that the writing
sheets may be separated from the carbon. sheets.
These methods generally involved the stitching
or gluing of the writing sheets and the carbon
10 sheets together along one margin, with the re
sult that when the writing sheets were detached,
the carbon sheets remained glued together and
were invariably thrown away since they could not
easily be used again.
Further when the writing sheets and carbon
sheets are stitched or glued together to form a
pad which is put through a typewriter, there
will be a tendency that the typing on the dif
ferent writing sheets will not be properly aligned,
To overcome
this objection, attempts have been made to tear
o? the stitched or glued margin of the pad. This
operation would tear or mutilate the carbon
together in superposed relation along one end a
margin as indicated at 31 A binding ‘I may be
glued over the glued edges if desired. Carbon

ing sheets I and extended beyondthe perforated
line 2 so that the same may be pinched between 10
the sheets by the fingers above the perforated
line 2 when it is desired to detach the writing
sheets. ‘These carbon sheets are shorter than the
writing sheets.
If desired, the writing sheets properly perfo- 16
rated may be alternately arranged with the car
bon sheets before the writing sheets are glued
at the end margins.‘ _By aligning the opposite

provide su?icient space for the extension of the
carbon sheets beyond such line as will later more
fully appear. The writing sheets are then glued

will occupy the relative positions shown in Fig- ‘
ure 1. In the positions shown, it will be noted
that one edge of each carbon sheet is located
at the line 5 a short space from the glued mar
gin of the writing sheets and a suitable distance 25
outwardly beyond the perforated lines 2 for the
pinching operation when the edges Ia of the
writing sheets are aligned with the adjacent edges
of the carbon sheets.

A further object resides in the provision of a
pad fromwhich the glued portion of the pad may
be detached without injuring the carbon sheets.
The invention comprises the novel structure
corner of a carbon sheet.

Figure 3 is a fragmentary elevational view illus

carbon sheets.
In accordance with this invention, a plurality
of writing sheets I are provided and each is
formed with a perforated or‘weakened line 2
gripped adjacent the margins Ia without grip
ping the carbon sheets, each of the latter is 35
provided with a cut-out of thumb'notch 6 which
may be of the form shown in Figure 1 or Figure
3. By gripping the pad with. one hand between
the lines 2 and 5 and gripping the sheets I at
the notches 6 or 6a with the other hand, it is 40
easily possible to detach the writing sheets from
the bound margin 3 by a pull that severs said
sheets I along the line 2. The carbon sheets,
being held by the hand gripping the bound mar
gin 3 are thus simultaneously separated from 45
the sheets I.
After the writing sheets are detached or sepa
rated, the carbon sheets may be released and
separated from the stub and reused as desired.
It should be noted that there is a su?lciently 50
wide unglued space between the perforated line
2 and the glued margin 3 of the sheets I for the
extension of the carbon sheets beyond the per
forated lines 2 for gripping purposes. In other
words, the carbon sheets extend beyond the per- 55
_ 2,129,875
forated lines a su?icient distance so that ‘they
maybe gripped or pinched by the ?ngers between
the writing sheets.
In order that the glued edge of a pad may be
detached without injuring the carbon sheets, one
of the upper corners of each carbon sheet is
clipped off as indicated by the dotted line B of
Figure 1. This renders it possible- to grip the
writing sheets at the clipped oiT corner indicated
10 by the dotted line 8 with one hand while holding
the body of the pad with the other hand for tear
ing o? the glued margin 3 of the writing sheets
along the perforated lines 2. As the carbon
sheets are unattached to the writing sheets, the
15 upper edges thereof will not be torn during this
operation, but said upper edges will project slight
ly, enabling them to be grasped easily in extract
ing the carbon sheets from between the writing
of said carbon sheets extending beyond said per
forated lines for gripping purposes and being un
secured to said writing sheets.
