COMPLETE SPECIFICATION.
improvements in or connected with Velocipedes.
I, JACOB HILGERS, of Viersen, in the Empire of Germany, Factory Proprietor,
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 various improvements in or relating to the construc-
tion of cycles, said improvements more particularly referring to a device for
locking the head of cycles, a new arrangement in connection with the brake and
a dustproof arrangement between the brake rod and the brake rod actuating
lever.
This invention is illustrated in the annexed drawings, in which,
Figures 1 to 4 illustrate the device for locking the head of cycles.
Figures 5 to 7 illustrate the arrangement of the brake spring, and
Figures 8 to 11 illustrate the dustproof connection between the brake rod
and the brake lever.
The device for locking the head of cycles is arranged as follows, it being
pointed out that the characteristic feature of this part of my invention is the
steering post being held at two points diametrically opposite.
Between the head tube a of the cycle frame and the steering post b a locking
ring is inserted, said ring being fitted with a square hole for the reception of
the square nut e. A corresponding square bore is provided in the head tube a
and, if necessary, in the lug g, the square nut e being adapted to pass these holes.
In the drawings, the device is shewn applied to the lug g, it being understood,
however, that it can be used in connection with any portion of the head tube a.
The uute is fitted at its inner edge with a flange of a diameter larger than
that of the square bore d in the locking ring c. A screw with a suitably milled
head is inserted in the nut c. The parts are arranged together as shewn in
Figures 1 and 2. In action, by turning the screw f, the nut the inner flange
of which is resting against the inside of the locking ring is pressed outwards
as soon as the screw touches the front wheel fork tube n, to which the steering
post is secured as usual. The movement of the nut e causes the locking
ring c to press against the fork tube n of the steering post b, thus tightly locking
gaid tube and post b at two points, i.e. the point and the point of contact of
the screw f, diametrically opposite one another.
The improved arrangement of the brake spring is characterized by not having
said spring, as heretofore, exposed, but by enclosing same in the brake rod
tube. On pulling the lever arm q upwards, as usual, towards the handle, said
lever arm q, being pivotted to the handle bar in the usual manner, causes the
brake rod, and with it the brake shoe o to descend; and, simultaneously, the
spring, situated inside the brake rod tube k, is contracted, by virtue of its
lower extremity resting on a projection m inside the guide bracket of the brake
rod tube k, the said guide bracket / being stationary on the frame of the cycle.
In the drawings, a suitable guide bracket is shewn in detail in Figures 6 and 7.
Referring to Figures 8 to 11 of the drawings, the dustproof connection between
the brake rod and the lever arm consists in having the extremity of the brake

page_text: lever a dished for the reception of the flattened head of the brake rod i. Part
of the circumferential wall is broken away to present a sufficient space for the
movement of the brake rod i, on turning the lever arm q around its fulcrum.
When the head of the rod i is placed inside the recess, the screw u is passed
through its centre bore and through a bore in the cup until its plate v is flush
with the wall of the recess. The bore in the cup may be screw threaded for
securing the screw 2, but if found convenient, a tightening screw nut may be
screwed on to the end of the screw protruding from the cup.
•
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:
-
1. A device for locking the head of cycles by locking the steering post at two
points diametrically opposite one another, consisting in the combination with
the locking screw of a locking ring and movable nut, substantially as described
and shewn.
2. In cycle brakes, having the brake spring located inside the lower split
portion of the braking rod tube, the lower extremity of said spring resting on
a support stationary with the cycle frame; substantially as described and shewn.
3. The arrangement of the head of the brake rod in a recess in the extremity
of the brake lever, substantially as described and shewn.
