A communication from the "C. BEHRENS ROLLWÄNDE AND JALOUSIEN FABRIK,”
of Hanover, in the Empire of Germany.
I, ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex,
Chartered Patent Agent, 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 portable shelter illustrated in Sheets I and II of the accompanying
drawings; in cross-section in Fig. 1, and in front elevation (partly in section) in
Fig. 2, consists of a number of wooden laths tt, flexibly united together by wires
in a well-known way, and divided horizontally into bays or compartments A by
broader wooden strips or rails T, the said bays being all of the same height and
each suspended between a pair or pairs of coiled springs s' and s² by means of
wires or wire-cords d passing through corresponding holes in the laths t which are
the component parts of the flexible partitions or shelters. The springs s s', are
lodged in recesses 6 in the outside and intermediate rails T', T; and the height of
the bays or compartments A, and the arrangement of the springs are so calculated
and proportioned that on the one hand the greatest extension of the wooden laths
or slats arising from exposure to atmospheric influences, and, on the other hand,
the stress upon the apparatus when the shelter is in use, combine to keep the
springs s in adequate tension, but at the same time without severing the connection
between them, a disadvantage which is so frequently met with in the case of the
usual shelters where the vertical wires run from top to bottom of the apparatus.
The coherence between the several bays is secured by the arrangement wherein
the broad rail T2 which forms the bottom border of the topmost bay A becomes
the top rail of the next following bay below. For this purpose, close by the recess
hollowed out in the said rail T2 to receive the bottom spring s of the upper bay, a
similar recess is hollowed out for the reception of the top-spring of the next lower
bav and so on.
It is evident that the bottom springs of the top bay may also be used for
suspending the wires d of the second bay (Fig. 5); nevertheless regard must be
had to the extension coefficients obtained with movable shelters.
To connect the springs s with the wires d, sheet steel discs c may be used
(Figs. 8 and 9) wherein two flaps n have been cut or stamped out on 3 sides and
then bent up so as to form a prism which will act as a firm point of support or
bearing (Figs. 3-5) for the wire when slung round it. In lieu of the disc c,
conical buttons or knobs e (Fig. 6) may be used, provided with a spring supporting
border, the wire d being joined thereto by slings or links, or by soldering.
Fig. 7 represents a cross i stamped out in sheet metal, with its four ends resting
on the spring s, and round which the wire may be slung in a simple manner.
The borings or recesses in the border rail T' are closed with plugs or by a fillet
fixed to the rail; whereas the recesses bored in the intermediate rails T' are
covered by the adjacent laths t on either side, which if necessary may be made
somewhat thicker than the others for the purpose.
Having now particularly described and ascertained the nature of this said inven-
tion as communicated to me by my foreign correspondents and in what manner the
same is to be performed, 1 declare that what I claim is ;-
1. A movable shelter made out of narrow flexibly-jointed wooden laths & joined

page_text: together which by broader intermediate wooden pieces or rails T2 are divided into
a number of equal and similar bays or compartments of large size whereof each
are held together by wires d stretched between coiled springs s¹ and s² while the
connection of the bays to each other is maintained by the bottom rail T2 of the top
bay at the same time forming the top rail of the next lower bay and so on in
: succession.
2. A movable shelter of the kind described in Claim 1 wherein the bottom
_suspension springs 3 of the first or top bay serve at the same time as top suspension
springs as the suspensory wires d of the next lower bay are secured to the said
.lower springs s³ of the next preceding bay instead of to special springs.
