We, PERCY LLEWELLYN FISON, of The Square, Ripon, in the County of
York, Bank Manager, and HARTLEY ILLINGWORTH, of Bingwood Terrace,
Ripon, aforesaid, Clerk, do hereby declare the nature of this invention to be as
follows:-
Our invention consists in manufacturing an envelope which when opened out
may be utilised for the purpose of writing a letter or memorandum and at the same
time to answer the purpose of an envelope.
In carrying out our invention we make the envelope-letter of paper of equal
thickness and in the first case it is made with the flaps opened out or in a distended
state so that, that portion of the envelope behind that which usually receives the
address, may be written upon to convey a message or memorandum or letter, after
which the flaps may be folded over in the ordinary manner and the gummed flap
sealed as usual. That portion of the flap which bends over may be partially cut,
so as to permit of the flaps being bent over, or they may be perforated at this
point which not only permits them being bent over but also permits the flaps being
severed so as to leave the central part intact in order that it may be filed or
otherwise used.

COMPLETE SPECIFICATION.
An Envelope Letter Sheet.
We, PERCY LLEWELLYN FISON, of The Square, Ripon, in the County of
York, Bank Manager, and HARTLEY ILLINGWORTH, of Bingwood Terrace,
Ripon, aforesaid, Clerk, 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 :-
Our invention consists in manufacturing an envelope which when opened out may
be utilised for the purpose of writing a letter or memorandum and at the same time
to answer the purpose of an envelope.
In carrying out our invention we make the envelope-letter of paper of equal
thickness and in the first case it is made with the flaps opened out or in a distended
state so that the reverse side portion of the envelope may be written upon to
convey a message or memorandum or letter, after which the flaps may be folded
over in the ordinary manner and the gummed flap sealed as usual.
Flaps at the bend may be partially cut or scored or they may be perforated so
that whilst thus allowing them to be bent against the reverse side of the envelope,
they may also be severed by pressure of the hand and leave the central part intact
in order that it may be filed or otherwise used.
In order that our invention may be fully understood, reference is hereafter had
to the accompanying drawings, wherein :-
Fig. 1 shews one of our improved envelope letter sheets in an open state and
Fig. 2 shews it closed and sealed for transmitting to its destination.
D

page_text: Fig, 3 is end elevation of Fig. 2 with the gummed flap open.
Fig. 4 is a modified form of envelope letter sheet.
Fig. 5 edge view thereof, and
Fig. 6 view of same when closed and sealed.
Referring to the drawings, the envelope letter sheets are made in one piece of
stout paper or card or mill board suitable for writing upon and comprise the
central part A, the gummed flap B and the side and bottom flaps C and D
respectively, which are intended to be sold and supplied in the open or extended
state as shewn in Fig. 1. The card or paper is scored or perforated on the 'four
sides as indicated by letter a and within this space the letter, memorandum, or
other matter is written, whilst the opposite or obverse side is for the address.
..When the letter has been written the flaps are bent or doubled over onto the
central part A as shewn at Fig. 2 and sealed by the gummed flap B.
"
'
On referring to Fig. 2 it will be observed that the flaps B, C, and D are cut at
corresponding angles and that the combined sizes thereof are equal to the area of
the central portion A whereby when folded they meet but do not overlap each
other with the exception of the tab B' which is gummed and overlaps the
extremities of flaps C and D and seals them.
In order that the flap B may not be raised above the surface of the other flaps
when the envelope letter is closed, we make the tab B' and also the greater
portion of the flap D rather thinner than the other portions of the envelope letter
so that when the flap B is folded over and sealed it is level with the other flaps.
In the envelope letter sheet shewn in Figs. 4, 5 and 6, the flaps are made to
overlap as in ordinary envelopes but being made of stout paper or suitable card
or mill board, we may make the flaps C and D rather thinner than the other
portions of the envelope letter, so that when closed upon each other they shall lay
flat.
In the case of the flaps C the requisite thickness of paper is removed from the
outer surfaces and in the case of flap D from the inner surface as shewn in
Figs. 4. and 5.
Letter E indicates the obverse side of the envelope letter.
On receipt of the envelope letter sheet, the flaps can be severed by slight
pressure of the hand and the central card bearing the letter or memo left intact for
filing.
The design or shape and the size of the envelope letter can be varied or altered
as required.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
1 claim is :-
The manufacture of an envelope letter sheet, perforated in the manner and for
purposes described and as shewn in the drawings.
