Improvements in Postal and other Tubes used for the Transmission
and Protection of Papers and other Articles.
1, PETER TYRER of Cranfield Lodge, Bexley Heath, Kent, Chemist, 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 my invention is to effect certain new and useful improvements in
postal and similar tubes such as are used for the transmission, protection or storage
of papers, drawings or other articles, and the said improvements are designed for
the purpose of facilitating the removal of the enclosed papers or other articles, and
at the same time securing them when placed in the tube and during transmission,
and thereby not only overcoming the difficulty often experienced in the withdrawal
of the said papers, when by reason of their elasticity or other cause they fit tightly
to the interior surface of the tubular case, but at the same time effectually securing
them from liability to slip out, or from accidental withdrawal at either end, when
they lie loosely in the tube case.
Reference being made to the accompanying drawings in which
Fig. 1 shows a postal tube with my improvement applied thereto.
Fig. 2 is an enlarged view of the same.
Fig. 3 is a section of a tube showing the hole and tongue hereafter described."
Figs. 4 & 5 show modifications of the shape of the tongue.
In carrying my invention into practice I form holes a. a in the body of the
tube A of any convenient shape or size in such a way and in such a position that
the papers, drawings or other articles enclosed may be taken hold of by the finger
and thumb and their removal facilitated.
At the outer end of each hole, a tongue is provided which, when the papers
or other articles are inserted in the tube, is pressed inwards by the thumb and
finger, thereby forming a lug or rib across the inside surface of the tube, thus
preventing the papers or other articles passing out of the tube in either direction.
The tongues are formed preferably at the outer end of the hole but may be
formed at the side of the hole, or at any part thereof if so required, and may
be of any shape or design as for instance those shown in Figs. 4 & 5. If
preferred the tongue may be formed separately from the hole and at any part of the
tube as shown at C,
in Fig. 6 or the tongue may be used without the hole as shown
at d, in Fig. 7.
When the papers are required to be withdrawn, the tube being made longer than
the papers or other articles enclosed the tongue may be pushed back from the
inside towards the outside of the tube by the finger or thumb until there is no
obstruction on the inside and then by pressing the thumb on the papers they may
be easily withdrawn.
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. As an improved article of manufacture, a tube for the transmission of papers
or other articles said tube having apertures in the substance thereof to facilitate
the removal of the contents, said apertures being provided with tongues formed
from the material of which the said tube is composed and which can he presse 1
inwards by the thumb or finger, thereby preventing the papers or other articles
enclosed, from slipping out of or being accidentally withdrawn from the tube,
substantially as described.

page_text: 2. As an improved article of manufacture, a tube for the transmission of papers
or other articles said tube having apertures in the substance thereof to facilitate
the removal of the contents and provided with tongues formed separately from the
said aperture by incision at any other part of the tube and which can be pressed
inwards by the thumb or finger, thereby preventing the papers or other articles
enclosed, from slipping out of or being accidentally withdrawn from the tube,
substantially as described.
3. As an improved article of manufacture a tube for the transmission of papers
or other articles provided with tongues formed by incision at any convenient part
of the tube and which can be pressed inwards by the thumb or finger, thereby
preventing the papers or other articles enclosed, from slipping out of or being
accidentally withdrawn from the tube, substantially as described.
