COMPLETE SPECIFICATION.
Improved Manufacture of Water and Dust Proof Cloth.
A communication from EDUARD FRANKENBERG, Manufacturer, of Hanover.
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 :-
دو
In the application and use of "mackintosh or vulcanized and impregnated
fabrics for sanitary and other purposes, as with all textile tissues in particular,
which are used for coverings or linings, there is always found this defect, that they
become warped baggy and ragged from the constant requirement of putting them
on and taking them off, and the wear incidental thereto.
In order to avoid this defect the process described in the following Specification
has been devised.
The accompanying drawings illustrate ;-
In Figure 1 a view of a covering, shown in
Figure 2 in section on the line n-n¹; and in
Figure 3 in section on the line n² n³.
On a durable fabric a bands or strips 6 of for example, ticking, are laid at
suitable distances apart the bands being fastened down with rubber solution or
other adhesive material, and ironed or rolled. Then in like manner the cross-
bands g are laid over the under layer of fabric and the longitudinal bands fastened
so that square or rectangular spaces are formed and enclosed by the bands. Over
the whole surface of the fabric are then spread gutta-percha sheets c, or a liquid
layer of rubber solution; and finally the fabric is covered with another sheet of
ticking, by manipulation with cold or hot rollers, box-irons or by pressing so as to
melt the gutta-percha sheets and cause the molten gutta-percha and the rubber
solution to permeate the pores and interstices of the ticking or other fabric d, the
bands or strips b and g and the fabric a which being pressed and dried forms an
intimately united covering which is impermeable by water and dust, and is equally
strong to resist distortion either in the direction of the warp or of the weft; while
the adhesive material fully preserves its elasticity, for which reason the material so
prepared is admirably adapted for use as under-blankets for beds, for bathing
establishments, for tents, tarpaulins, wagon-covers, tilts and many other purposes.
For the sake of greater durability the longitudinal and transverse bands b, g, after
the cover is finished may further be sewn to the fabric a and d.
The manufacture may be modified as for example, as shown in Figures 4, 5 and 8,
by sticking the fabrics a' and d' together and fastening the bands 6' and o¹ on the
upper or underside of the combined fabric, either by sticking or sewing; also
by the use of a simple impregnated fabric, with the same cross-bands sewn or stuck
upon it.
With a view to the greater convenience of fastening the covering on the
bottom or sacking of beds, metallic eyes o may be provided as shown in Figures 16
and 7.
Having now particularly described and ascertained the nature of the said inveu-
tion as communicated to me by my foreign correspondent, and in what manner the
same is to be performed, I declare that what I claim is ;—
1. The manufacture of water and dust-proof coverings and underlays which shall
not be liable to warp in any direction characterized by

page_text: (a) An impregnated fabric or two layers of such fabric a¹ and d¹ joined
together by gutta-percha rubber solution or other suitable adhesive material
with the aid of pressure and heat and provided with longitudinal and trans-
verse bands 6 and g' arranged at certain distances apart crossing each other
and stuck or sewn thereon.
(6) A layer of fabric a having such longitudinal and transverse bands band g
stuck thereon and over them a layer of gutta-percha sheets or of liquid
rubber solution or the like spread over it and the whole covered with a
second layer of fabric d after which with the aid of pressure and heat the
two layers of fabric as well as the cross-bands are all joined together by
means of an adhesive material which is also pressed into the pores of the
whole so as to make the entire cover water and dust proof.
The water and dust proof fabric substantially as described and illustrated in
res 12 and 3 of the accompanying drawings.
The water and dust proof fabric substantially as described and illustrated in
res 4 5 6 7 and 8 of the accompanying drawings.
Dated this 26th day of January 1894.
