Improvements in Apparatus for Securing Spokes in Velocipede
and similar Wheels.
I, PAUL HONTSCHKA, of Bohrauerstrasse 7, Breslau in the German Empire,
Manufacturer, 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 an apparatus which is intended to be employed in
conjunction with centring machines for velocipede wheels and other wheels fitted
with wire spokes, and its object is to enable the spokes to be tightened and secured
to the rim in less time and more conveniently than at present. My improved
appliance or apparatus is illustrated by the accompanying drawings and will be
hereinafter described with reference thereto.
Figure 1 represents a side elevation of a wheel centring machine with my
apparatus applied thereto.
Figure 2 shews a sectional side elevation of the apparatus separately and drawn
to a larger scale.
Figure 3 illustrates in sectional plan and
Figure 4 in sectional side elevation, the front part of my apparatus drawn to a
still larger scale.
Figure 5 shews, in end elevation, one of the spoke nuts.
The apparatus is supported and attached to the centring machine by the screwed
stem A and suitable nuts. To enable it to be moved in a vertical plane, so as to
adjust it in its working position, it may be pivoted to the stem at 6. The base a
of the apparatus carries, in suitable bearings, the circular slide bolt e, which can
be rotated by the hand-wheel f. Between the bolt bearings q q', there may be
fixed on the bolt e, a collar r, between which and the bearing there is arranged
the spiral spring g, which tends to force the bolt continually in the direction of
the wheel d, into which the spokes have to be fitted. At the front end of the
bolt e, there is a forked screw driver l, formed upon the front end of the circular
rod s, the tail end of which is tapered and fits into the corresponding hole in the
front end of the bolt e. At the back end of this hole, a transverse slot t may be
formed to facilitate the removal of the screw driver when required. A sleeve m
is arranged upon the screw driver so as to project beyond its point and to encircle
the outer end of the nut c, and thus aid in centring the screw driver. The sleeve
can slide on the screw driver, but its motion is limited, for example, by the slot n
therein and the pin o, fixed in the screw driver. Between the sleeve m and the
tail k, there is a spiral spring p which normally tends to push the sleeve forward
over the point of the screw driver as seen in Figure 3. It is an advantage if the
inside front edge of the sleeve be tapered so as to more readily centre the point of
the screw driver in the radially slotted nut c.
In using the apparatus, the fly wheel is drawn back into the position indicated
by the dotted lines Figure 2; the wheel d is turned to bring the next spoke into
line; and the fly wheel is released to bring the screw driver and sleeve over the
nut of the following spoke. The screw driver having engaged the nut, the hand

page_text: wheel is rotated so as to screw the nut up after which the hand wheel may be
again pulled back and the cycle of operations be repeated. If the point of the
screw driver should not fall direct into the nut slots, the spring g will force it
therein as soon as the point comes in line with the slots. As the sleeve m
surrounds and centres the nut during the whole of the tightening process, it is 5
impossible for the screw driver to leave its work."
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
(1. 1. *2**
:
1. Apparatus for screwing nuts upon the spokes of velocipede and other like 1
wheels, constructed arranged and operated substantially as herein before described
and as illustrated by the accompanying drawings.
2. In apparatus for screwing nuts upon the spokes of velocipede and other like
wheels, a rotary sliding bolt normally pressed forward by a spring and having at
its forward end a suitable screw driver surrounded at its point by a sleeve which
also is normally pressed forward by a spring, constructed arranged and operated;
substantially as herein before described and as illustrated by the accompanying.
drawings.
