COMPLETE SPECIFICATION.
Improved Combined Letter Sheet and Envelope for Correspondence
and Advertising Furposes.
I, RUDOLF VON SCHWARZENHORN, Neue Rosenstrasse 1", Altona, Germany,
Captain, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by
the following statement:-
The object of this invention is to provide a sheet of letter paper, forming a
single piece with its envelope, the distinguishing feature being that the envelope
or that part of the sheet which is employed for fastening up the letter, which is
made fast by means of its flaps to one part of the sheet when the letter is closed,
bears on the inside advertisements or illustrations.
In consequence of the peculiar arrangement of the part of the sheet or envelope
which is employed for fastening up the letter, the envelope remains attached to
the sheet after the folds of the flaps have been slit, and thus the time of delivery
of the letter is always ascertainable by means of the post office stamp on the
envelope.
The application of advertisements to the envelope can be shown to be advan-
tageous, as owing to the part which furnishes evidence of the time of dispatch of
the letter, remaining attached to the remainder of the sheet after the letter has
been opened, the advertisements will from time to time be again brought under
the notice of the owner of the letter and thus in consequence of the enormous
extent to which letters are used will be widely circulated. Such circulation will
also be very inexpensive, involving little more cost than the postage.
In the accompanying drawing, the invention is illustrated in three different
forms.
Fig. 1 shows the letter in its folded form.
Fig. 2 is a front view of the combined letter sheet and envelope when unfolded.
Fig. 3 is a back view of the same. Figs. 4 and 5 are similar views to Figs. 2
and 3 showing a modified form of letter sheet. Figs. 6 and 7 are also similar
views to Figs. 2 and 3 showing another modification.
a is the sheet of letter paper, b the part of the sheet which is employed for
fastening up of the letter viz., the envelope and c are the flaps of the latter.
As the flaps must be made to adhere to the sheet of letter paper itself, and the
part in question is not fully covered by them it is necessary if it be not desired to
divide the sheet, that the opening should only be effected by slitting the folds
of the flaps.
In all cases, the part of the sheet employed for fastening up the letter is
"hatched," or lined diagonally. It is intended that this part should be printed
or illustrated.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. A sheet of letter paper with envelope, produced in a single piece, the flaps of
which envelope must be made to adhere to the sheet of letter paper itself, when the
letter has to be fastened up, one part of such sheet bearing advertisements or
illustrations.
2. The improved combined letter sheet and envelope for correspondence and
advertising purposes substantially as described.
