striking a drum gong tambourine striking a steel triangle or sounding a wood
rattle drum or bell by a revolving toothed wheel or wheels attached to the friction
wheel made to raise a spring or hammer for to give a signal or alarm applicable to
and may be fixed to any required part of a bicycle tandem tricycle carriages coaches
cabs hansoms omnibuses mail carts mail vans tramcars carts waggons drays fire
engines or other wheeled vehicles by constructing a metal or metallic air pump or
pumps rotary fan or bellows fixed in a frame for charging a compressed air accumu-
lator suitably fitted with air inlet openings and reducing valves air outlet openings
having metal metallic flexible or other outlet air blow pipe or pipes attached to air
outlet openings of an air pump or pumps rotary fan bellows or compressed air
accumulator by brazing soldering screwing or other suitable means or the discharg-
ing end of an air blow pipe or pipes are made having a screwed thread on the
inside or outside or otherwise formed to receive a screwed metal metallic flexible
or other suitable formed blowing end or ends of a whistle reeded horn bagpipe or
other wind instrument and on lowering the frame and friction wheel by working
of a lever through a guide rod or rods on to the rim nave or hob of a wheel
momentry motion may be given to the friction wheel to give a signal or alarm as

in charge of a conveyance.
When the frame work of a bicycle tandem or tricycle are constructed of strong
hollow tubing with air tight joints such answers as an air accumulator when fitted
with valves air inlet and outlet air blow pipe suitably attached to a whistle trumpet
or other sound producing instrument and the power to work an air pump or
bellows to charge the hollow tubes with air may be obtained by the rotation of the
'friction wheel giving motion to the air pump or bellows.

Improvements in or relating to Audible Signals or Alarms for
Bicycles, Road Vehicles, and the like.
I, GEORGE RYDILL, of 20, Back Lawson Street, Dewsbury, Merchant, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following state-
ment:
This invention has reference to improvements in or relating to audible signals
or alarms for bicycles road vehicles and the like by constructing and attaching
to any required part of a wheeled vehicle or vehicles a movable metal frame having
metal guides or metal guide rod or rods for carrying a friction wheel or wheels air
pump or bellows working and supported in a metal slide guide or guides attached
to a vehicle made in any suitable form or material. The friction wheel or wheels
are fitted with a metal shaft passing through the friction wheel or wheels, and
the projecting ends of this central shaft are for the attachment of a crank or cranks,
cam or cams, eccentric or eccentrics, metal rod or rods, pulley or pullies, for work-
ing, say, an air pump or bellows, which may be actuated that is raised or lowered,
by, say, a lever and a metal or other spring so that the small friction wheel con-
nected to the metal frame is made to rotate, when desired, by the friction of the
outer rim of a wheel, or india-rubber tube or an inflated air tube rim, or nave or
hob of a bicycle or other wheeled vehicle, for sounding a whistle, reeded horn or
other wind instrument connected to said air pump or bellows.
The apparatus may be fixed to any required part of a bicycle, tandem, tricycle,
carriage, coach, cab, hansom, omnibus, mail cart, mail van, tramcar, cart, waggon,
dray, fire-engine, or other wheeled vehicle by constructing a metal or metallic air
pump or pumps, or bellows, fixed in a frame, suitably fitted with air inlet openings
or valves, and air outlet openings, by soldering, brazing, screwing or other suitable
means.
In the drawings hereunto annexed :—
Figs. 1 and 2 are enlarged sectional elevations drawn at right angles to each
other of one form of alarm apparatus constructed according to this invention,
showing an air cylinder or pump.
Fig. 3 shows the same applied to a bicycle.
Fig. 4 is an enlarged sectional elevation of another form of alarm apparatus
constructed according to this invention, showing bellows applied thereto.
Like parts in all the views are marked with similar letters of reference.
A is the framework of the bicycle, BB the wheels provided with tyres C of
any suitable and well known construction. D the saddle, E the pedals and driving
gear, F the handle bar, and G the brake lever.
All the above mentioned parts are of ordinary and well known construction.

page_text: To the brake lever G is connected, by any suitable and well known means,
such as say by lugs h and nuts h¹ to its screwed end-the bifurcated framework H
closed at one end, in which is mounted or fixed the air cylinder or pump I as shown
at Figs. 1 and 2, or bellows R as shown at Fig. 4.
At Figs. 1 and 2 in the air cylinder or pump I reciprocates the piston or
plunger J to which the necessary motion is imparted from the periphery of tyre C
through friction pulley K mounted on shaft L, carried in suitable bearings in the
bifurcated framework, eccentrics or cranks M, connecting rods N, and piston
rod O. The closed top of the bifurcated framework is armed with a whistle, fog-
horn, or other alarm P; and in order to provide for the admission of air to the
pump or cylinder L it may also be armed with one or more valves. A clack
valve Q is shown in the drawings.
At Fig. 4 in place of the air cylinder or pump I, bellows R are shown, which
may work in guides or,--as shown in the drawings,-in a cylindrical case I con-
nected to the bifurcated framework H. The bellows are opened and closed by
the rotation of the friction pulley K and eccentrics M through connecting rod N
and bellows rod 0, the alarm being given by the air being forced out of the
whistle P as in the previous case. The air is admitted to the bellows by means
of the clack valves Q.
Whenever the periphery of the friction wheel K comes in contact with the tyre C
of the bicycle by the action of the brake lever G, motion will be conveyed to the
piston J or bellows R and an alarm given.
Instead of attaching the apparatus to the brake mechanism the framework H
and parts connected therewith might be pivoted,—say for a cab or other vehicle,-
to the framework of the vehicle, so as to be capable of being raised or lowered
by means, say, of a cord or chain, so that whenever the periphery of the friction
wheel K comes in contact with the nave or other part of the wheel of the vehicle
motion will be imparted to the piston for sounding an alarm.
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. An audible alarm apparatus for vehicles and machines in which the alarm
apparatus is intermittently operated from the wheel of the vehicle or machine by
means of a friction pulley working through eccentrics, cranks, or gearing as set
forth..
2. In audible alarm apparatus for vehicles and machines, the combination of a
bifurcated framework,--mounted on or pivoted to the vehicle or machinery-having
an air pump, bellows, or cylinder and audible alarm mounted thereon, a piston
reciprocating in said air cylinder intermittently actuated by a friction pulley and
parts connected therewith whenever the periphery of the said pulley is brought
into frictional contact with the periphery of the nave or tyre of the wheel of the
vehicle or machine, substantially as herein described and illustrated in the annexed
drawings.
