AN IMPROVED FASTENING WITH SLIDING ATTACHMENT FOR THE FLAPS OF TROUSERS
Year: 1885

page_text: I FRANZ PODUSCHKA of N° 46 Kirchengasse in the City of Vienna, Austria,
Mechanist, do hereby declare the nature of my Invention for AN IMPROVED
FASTENING WITH SLIDING ATTACHMENT FOR THE FLAPS OF TROUSERS to be as
follows:-
My invention relates to an improved fastening with sliding attachment for the
flaps of trousers or pantaloons the object of which is to render the present
disagreeable buttoning system superfluous and to replace the same by a reliable
readily operated mechanism.
The parts are sewn to the inner surface of the trouser flap one part on the right
the other on the left hand side of the same and covered as customary by the stuff
or material of which the trousers are made.
These said parts consist of metallic spirals which are covered by or clad with
drill, leather or other suitable material.
These two spirals and consequently the two sides of the trouser flap are connected
by means of slides which said slides are held equidistant from each other by means
of a band or its equivalent.
The upper slide fits snugly over a strip or small plate of metal or other material
attached to one of the side parts so as to have so much frictional contact with the
same that the said upper slide does not slide easily whereas the small plate is
larger than the opening in the slide and prevents the same from leaving the spiral
spring.
All the slides are so arranged that they surround the spirals and are provided
with a small plate which is soldered or otherwise attached to the same and serve
to clamp the band and hold the same fast.
The lower slide is arranged to be taken hold of and slid or pushed up and down
for opening or closing the flap. If it is desired to open the flap the slide is pushed
up and carries the intermediate slides with it until they come in contact with the
upper slide whereby the band is folded up.

page_text: In order to close the said flap it is only necessary to slide or push the lower slide
down as far as the tension on the band or cord will permit.
The lower slide is prevented from leaving the spirals by means of the upper
slide and band; if however it is desired to open the trousers the upper slide is
freed from its frictional contact with a small plate of metal, is pushed down to the
lowest point of the spirals and carries the other slides with it so that the parts
which are sewn to the inner surface of the trouser flap are given free and the
trousers can be opened the same as now customary.

page_text: In order to close the said flap it is only necessary to slide or push the lower
slide p down as far as the tension on the band tape ribbon or cord w will permit.
The slide pis prevented from leaving the spirals by means of the slide m and
band w; if however it is desired to open the trousers the slide m is freed from its
frictional contact with o, is pushed down to the lowest point of the spirals and
carries the other slides with it so that the parts t¹ are given free and the trousers
can be opened to their full extent.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The construction of an improved fastening with sliding attachment consisting of
slides which are held equidistant by means of a suitable band, tape, ribbon or its
equivalent which said slides embrace the parts t¹t in order to assure the ready
opening or closing of the trouser flap as substitute for the ordinary button and
buttonhole fastening substantially as and for the purpose described in the foregoing
specification and shown in the accompanying drawings.
