PROVISIONAL SPECIFICATION.
Improved Signal Apparatus for Bicycles, Tricycles, and like
Vehicles.
I, THEODOR WEISSER, of Voehrenbach, Grand Duchy of Baden, German Empire,
Engineer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to construct sound producing mechanism for use
with a bicycle, or a tricycle, or other vehicle and arrange such mechanism in
connection with the break rod, that by a depression to a certain distance the sounds
can be rapidly obtained, and by a greater depression the break can be applied to the
wheel, the sounding appliance such as the hammer being then thrown out of action.
For the purpose of my invention, I affix to the break rod a bracket, the front. end.
of which carries a bell, or other like sound giving instrument, I pivot a lever to the
bracket and by means of a spring, the hammer crank is pressed into contact with a
wiper cam, this being on an axle of and moves round with a small wheel capable of
rotation and affixed to the front end of the lever from bearing on the periphery of
driver or other wheel of the machine.
'
The lever is held in a suitable position by a separate spring affixed to lug on the
fork, or on the frame of the machine, so that when the break handle is first actuated,
a tension is put upon this spring, the pressure on the break handle being sufficient
to lower its rod for sounding the alarm, but by a continued grip of the break handle,
the rod become lowered sufficiently to apply the break, said additional lowering
causing a greater, angle to be assumed to the hammer crank to move it out of range
of the wiper wheel to stop the ringing.

COMPLETE SPECIFICATION.
Improved Signal Apparatus for Bicycles, Tricycles, and like
Vehicles.
I, THEODOR WEISSER, of Voehrenbach, Grand Duchy of Baden, German Empire,
Engineer, 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 signal apparatus constituting this invention has great preference above all
apparatus now in public use, that it can be operated without special attention, activity
or efforts and without stopping the travel of the machine. It gives loud signals
with rapid quickness. The lightest pressure on the brake-lever of the machine is
sufficient to give the signal without actuating the brake. An additional pressure
easily operates the brake to check or stop the machine.
This apparatus consists in the following parts as indicated by the annexed drawings.
1. In a fixable arm A formed with two cramps N, N, standing one a little higher
than the other and furnished with adjusting screws, to fasten the apparatus on edge to
the vertical brake-bar of the machine.
2. In a lever B pivotted parallely to the arm A.
3. In a little wheel C striated on its periphery and mounted on an axle D fixed into
the fore end of the lever B.
4. In an eccentric E fixed upon the wheel C to move with this wheel.
5 In a lever I unan

furnished at. the upper end with a bell-hammer, and below with its fore-end ourved
directly under the periphery of the eccentric.
6. In a spiral spring K fixed upon a pin L of the arm A and curved vertically to
form a hook M engaged with the rod J regulates the movements.
7. In a bell O.
8. In a spiral spring P connected to the lever B and to the steering post of the
machine.
The apparatus operates in the following manner;
When the brake-lever of the inachine pressed, the brake-bar goes downwards and
with it in corresponding manner, the signal apparatus. By this, the spiral spring P
will be drawn, (put in tension), and draw upwards the hind part of the lever B, and
in consequence the fore part of said lever will go downwards to press the little
wheel C upon the travelling wheel Q of the machine, periphery upon periphery. By
the friction produced thereby, the little wheel C will be turned round by the great
wheel of the machine and with it also the eccentric, which permits of the rod J
escaping from the tooth and causing the hammer to strike the bell in rapid
succession.
If however the brake is intended for use to stop the machine, the signal apparatus
suspends its' function because the brake-lever will be pressed down so far as to carry
the rod J-below-the edge of the eccentric E, the little wheel C being strongly pressed
upon the driving wheel.
Having now, particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1. A signal apparatus for bicycles and tricycles (velocipedes) and similar machines,
fixable to the brake-bar and following its movements and capable of being drawn
upwards by means of a spiral spring jointing the apparatus with the post of the
machine and pressing thereby a little wheel C downwards upon the driving wheel of
the machine, an eccentric E to move around and press upon the rod J down and
upwards by a spring K to operate a bell hammer, as set forth.
2. A combined apparatus by which signal appliances can be thrown out of action by
additional pressure when the brake has to be applied to check, or to stop the
machine.
