Improvements in Sliding Ferrules or Means for Retaining the Ends
of a Series of Wires, Rods, or the like, especially applicable for
Umbrellas.
We, MAX AUGUST THEO DRAEGER, and HEINRICH WILHELM JOHANN
ZEECK both of 10 Wilhelmstrasse, Hamburg, Germany, Manufacturers 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 :-
This invention relates to a sliding ferrule or movable collar or the like means
for retaining the ends of a series of rods ribs wires or the like for instance the
series of ribs on an umbrella stick such that one single simple movement (viz::
moving this novel retaining collar in one direction only) suffices to enclose the rib
ends and similarly also to release the same.
The accompanying drawings illustrate the invention in two forms of construction
as applied to an ordinary umbrella stick.
Figs. 1, 2 and 3 are longitudinal sections of one form of construction in three
different positions.
Fig. 4 is a section on the line A--B Fig. 2.
Fig. 5 shows details.
Figs. 6 to 8 show another form of construction in three corresponding positions,
and
Fig. 9 is a section on the line C-D of Fig. 7.
On the umbrella stick a is mounted a sleeve b with a shoulder b¹ against which
bears one end of a spiral spring e the other end of which presses against a
shoulder d on the collar d.
The sleeve b is formed towards the end furthest from the rib ends with a
groove 6 in which works a loosely mounted ring f.
A sleeve e provided with split ends (imparting a spring to same) is also attached
to the collar d.
Fig. 1 shows the position in which the rib ends are released. The said split
ends on c rest in such case on the lower portion of the sleeve b.
When it is desired to fasten the rib ends the operator simply grasps the collar d
and moves it (in the direction of the arrow in Fig. 1) until it has assumed the
position shown in Fig. 2. When this is done the ends on c catch into the groove b³
below the ring fand thus lock the collar in position.
If it be now desired to release the rib ends it is merely necessary to move the
collar in the same direction as before until the spring ends on c (which have a
shape such that they can pass out of the groove only in one direction in an
upward direction as shown in the drawing) pass on to the ring f.
As soon as this is done the spiral spring e which was previously compressed will
exert its force and press the collar back into the position shown in Fig. 1.
Fig. 3 shows the position in which the sleeve c with its spring ends is just being
pushed back. In this fig. the main portion of the collar d and the entire spring e
re both omitted.
The form of construction illustrated in Figs. 6 to 9 only differs from that just
described in that instead of the sleeve c furnished with spring ends there is
employed a spring sleeve c which is provided with a nose or projection c¹.
The mode of operation of this construction is as follows:-
In this case also the operator grasps the sleeve d and moves it in the direction
of the arrow from the position shown in Fig. 6 into that shown in Fig. 7. Then

page_text: the spring nose c' places itself in front of the shoulder d¹ and thus locks the
collar d in position.
To release the rib ends the same mode of proceeding is employed as in the case
of the first form of construction namely by moving the collar d further in the
same direction. By this means the nose c¹ is pressed down by the loose ring f
and moves back until the shoulder d¹ (against which the springe bears continually)
can move freely over the nose the loose ring being carried along and the collar
springing back into its original position.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. A device for retaining and releasing the rib ends on umbrella sticks or for
the like purpose consisting of a sliding collar moving upon a fixed sleeve adapted
when moved in one and the same direction to secure the rib ends etc. to be held
together or enclosed and also to release same the arrangement being such that the
said collar is locked as soon as it has moved into the closing position whilst by
continued movement of the said collar in the same direction the collar is released
and is thereupon pushed by a spring back into its original position substantially as
and for the purposes herein before set forth.
2. A device for the purposes specified consisting of the combination of a sleeve
such as ba collar such as d niounted on said sleeve another sleeve such as c
connected to said collar d adapted to be moved into the groove 63 and by these
means lock the collar in position whilst on further moving the collar in the same
direction the spring ends c bear upon a ring which is movable in said groove and
carry the ring along with them acting in conjunction with a spring such as e which
then presses the collar d back into its initial position substantially in the manner
and for the purposes hereinbefore described and illustrated in Figs. 1 to 5 of the
drawings hereunto annexed.
3. The modification of the device claimed above-such modification consisting
of the arrangement and combination with the foregoing of the spring nose c' fixed
to the stick having a shoulder therein or thereon which is adapted after the first
movement of the collar to lock the latter in position whilst on further movement
of the collar in the same direction a loose ring f causes the spring nose c¹ to be
pressed down in conjunction with a spring such as e adapted to return the said
collar d back again into its initial position substantially in the manner and for the
purposes herein before described and illustrated in the drawings hereunto annexed.
