Improvements in Connecting the Tubes Forming the Framework of
Bicycles and other Framed Structures.
I, EMILE WOSCIIKE, Manufacturer of 190 Rue Vanderlinden Schaerbeck Brussels,
Belgium, do hereby declare the nature of this invention to be as follows:-
The invention has for its object to construct a frame for Bicycles, Bedsteads,
Tents, Pavilions, and other frame structures which may be easily dismounted.
My improved frame consists of tubes of steel, in the conically formed ends of which
left and right-hand screw threads are pressed (not cut) so as not to weaken the
sides of the tube.
The conical ends of the tubes are adapted to screw into nuts fixed on connecting
pieces, which nuts are provided with slots or saw-cuts at their ends. As soon as
the tubes are screwed home the slots or saw-cuts are contracted by small screws,
and the tubes thereby fastened and screwed to the connecting pieces.
To dismount the frames the small screws are loosened and the tubes are turned
so as to screw out of the connecting pieces.

Improvements in Connecting the Tubes Forming the Framework of
Bicycles and other Framed Structures.
I, EMILE WOSCHKE, Manufacturer of 190 Rue Vanderlinden Schaerbeck Brussels,
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:-
My invention relates to a frame easily taken apart applicable for cycles, tents,
carrying frames or other framed structures in which the parts to be put together
consist of tubes whose conically formed ends are provided with impressed threads
which engage in correspondingly formed connecting pieces which act as matrices
and are provided with a slit and wherein the same are firmly drawn together by

page_text: means of screws and matrices for greater safety. In order to facilitate quick release
of the tubes each is provided with a right and left thread respectively.
Referring to the accompanying drawing:
Figures 1 and 2 show a tubular connection in longitudinal and cross section.
Figure 3 shows on a larger scale a cycle frame constructed according to my
invention.
Figures 4 and 5 show a modification of the connecting pieces.
The tube A formed of a metal pipe or other sheet metal piece is provided at its
two coned ends with impressed threads, a right and a left respectively. These
coned ends BB fit into correspondingly shaped matrices CC of the connecting
pieces DD. The matrices C are provided in front with slits which after the
insertion of the tubes can be drawn together by means of the screws G put through
the flanges F, in order to secure a firm fastening in this manner.
In order to release the tubes A it is only necessary to turn the same after removal
of the screws G and the release is immediately effected by means of the right and
left thread.
Figures 4 and 5 show a modification. which is especially applicable for the
securing of the forks of cycles for instance. In this case the slits are cut in the ends
of the tubes themselves which in this case are formed cylindrical. After the
tube has been inserted from below in the conical matrix C the screw H which is
also conical and in the shape of a stopper is screwed in, whereupon by the widening
out of the slot I a firm pressing of the thread into the matrix results. Upon the
releasing of the screw the tube ends again assume the cylindrical shape owing
to their elasticity..
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I would have it under-
stood that I am aware of the Specification of Letters Patent No. 24,301 A.D. 1895
granted to James Richard Trigwell and I do not claim anything described and
claimed therein, but I declare that what I claim is:-
1. A detachable frame for cycles, tents and the like consisting of metal tubes
whose conically shaped ends are provided with impressed right and left threads
which ends engage in correspondingly formed connecting matrices provided with
slots substantially as described.
2. A modification of the arrangement set forth in Claim 1 consisting in the
forming of the tube ends cylindrically and providing the same with slits whereby
the fixing thereof is effected by means of a conical screw inserted from above
into the tube.
