PROVISIONAL SPECIFICATION.
Improvements in Spurs, and in Alarm Apparatus for use by
Cyclists.
I, ARVED JURGENSOHN, of Hauptstrasse 22 B, Schöneberg, near Berlin, in the
German Empire, Journalist, do hereby declare the nature of this invention to he a
follows:-
The subject of the present invention is a new kind of alarm or signal apparatus for
cyclists, to be worn on the heel and set in action by movement of the foot.
The alarm mechanisms at present in use by cyclists have the disadvantage that
they are sounded intermittently or spasmodically, and hence frequently only at the
moment before an impending collision, so that foot passengers receive a sudden shock,
and often in their confusion lose time in stepping out of the way, being consequently
run over. All these inconveniences are obviated by the cycling spurs forming the
subject of this invention, which instead of emitting a harsh sudden spasmodic noise
as the present alarms, give forth a continuous pleasant musical tinkle. Small bells
or jingles fastened to the handle of the cycle do not serve the same purpose,
since
the motion of this part of the machine is often insufficient to properly sound them.
The spur, on the contrary, being attached to the heel of the wearer, whose feet are
continuously moving on the pedals, emits a sound even when the cycle is passing
over the smoothest asphalte, hence greatly contributing to the avoidance of accidents,
particularly in crowded streets where the approach of the noiselessly running cycle is
scarcely heard.
Again, when, as is frequently the case in towns, the cyclist has to dismount and
wheel his machine, the motion of his feet in walking causes the alarm to sound, and
thus, to mutual advantage, give drivers and foot-passengers warning of his approach.
In cycle processions, parades, races, excursions, tandem rides, cyclists' dances and
the like, the new spur, on account of its agreeable sound, will be found most
acceptable, especially if jingles of harmonising sound.be chosen.
The invention whilst serving a most practical purpose as an alarm or signal, also
forms a perfect symbol for the "knight of the iron steed," in every way corresponding
to the spur of the horse-rider; and like the ordinary rider's spur it will certainly find
extensive use as an ornamental appendage.
In its essential form the invention consists of a base or body of any form which may
suitably be attached to the heel of the rider, carrying a bell or jingle or other alarm
or signal apparatus, sounded by means of a ball, clapper or the like.
On the drawing,
Fig. 1 shews the invention in a form very closely resembling an ordinary horse-
man's spur, consisting of a base or body a b c d, composed of a fork a b and a neck d,
the latter having at its outer extremity, at the place where in the horseman's spur
the knob or rowel is applied, a bell or jingle e. The sharp spike c is for the purpose
of driving into the shoe heel, in order to afford greater security of fastening.
Fig. 2 is a modification of the spur, the jingle e being here shown as substituted by
a clapper-hell.

page_text: Fig. 3 shews another modification, in which the bell is dish-shaped and is struck
by a hammer f. On its extremity is a sharp point g, so that the spur may also be
used by horseinen.
•
Fig. 4 shews a variation of the form illustrated in Fig. 3, likewise adapted for
horsemen, the bell carrying at its extremity a small rowel h.
Figs. 5 and 6 shew other forms, wherein the bell or jingle e is provided with
points g, g-g, to render it applicable as a rider's spur.
Although the base or body inay be conveniently made in the form of an ordinary
horseman's spur of any usual form, such as box, buckle or screw-spur, this, as above
mentioned, is by no means essential to the invention, since any other form, such as
a spiked plate, single spike, screw or the like, which lends itself to attachment to the
heel, will answer the purpose equally well.
Fig. 7 shews such a modification of the invention, the spur fork of Fig. 1, being
here replaced by a bent plate, having holes in it, by means of which it may be sewn
to the boot. In this case the neck dis shortened, so as to form merely a junction-
piece between the body or plate a and the bell e.
In Fig. 8 the lower part a of the neck forms the base or body, and has a sharp
spike (which may, if desired, be provided with a screw thread) for insertion into the
heel of the foot.
Fig. 9 shews the jingle e formed as a separate piece from the body and neck d, and
attachable by screwing. The jingle can then be changed for a corresponding part of
another modified form of the invention, or for the head of a horseman's spur adapted
for the purpose. In Fig. 9 the male screw is shewn on the neck d and the female
screw on a short neck d¹ projecting from the jingle e. Fig. 9ª shews the female screw
situated internally of the jingle. Or the male screw thread may be on the jingle and
the corresponding female thread on neck d.
Fig. 10 shews a modification in which in the base ab there is a slot i to receive
the correspondingly tenon-shaped tongue of the neck d. Or, vice versa, the slot
may be formed in the neck d and the tongue i¹ on the base a b.
Fig. 11 shews a form of particularly light execution, especially adapted for cycling
shoes. The body a b d is here formed of a sheet of thin metal having three
points for insertion into the shoe, and holes to enable it to be stitched to the
inaterial of the shoe.
Fig. 12 shows the same modification in its bent forin ready for application to the
shoe. Instead of the form shewn, the plate may be round, star shaped, triangular,
rectangular, or of other convenient form, and the number of the points or holes
altered, or one or both altogether dispensed with.

Improvements in Spurs, and in Alarm Apparatus for use by

J, ARVED JÜRGENSOHN, of Hauptstrasse 22 B, Schöneberg, near Berlin, in the
German Empire, Journalist, do hereby declare the nature of this invention 4
an in what inauner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The subject of the present invention is a new kind of alarm or signal apparatus
for cyclists, to be worn on the heel and set in action by movement of the foot...
The alarin mechanisms at present in use by cyclists have the disadvantage, that a

this invention, which instead of emitting a harsh sudden spasmodic noise as the
present alarins, give forth a continuous pleasant musical tinkle. Small bells or
jingles fastened to the handle of the cycle do not serve the same purpose, since the

thus, to mutual advantage, give drivers and foot-passengers warning of his approach,
In cycle-processions, parades, races, excursions, tandem rides, cyclists' dances and

The invention whilst serving a most practical purpose as an alarm or signal, also
forms a perfect symbol for the knight of the iron steed," in every way correspond-
ing to the spur of the horse-rider; and like the ordinary rider's spur it will certainly
find extensive use as an ornamental appendage.
In its essential form the invention consists of a base or body of any form, which
inay suitably be attached to the heel of the rider, carrying a bell or jingle or other
alarm or signal apparatus, sounded by means of a bill, clapper or the like.
On the drawings, that filed allready with the provisional specification-Fig. 1
shews the invention in a form very closely resembling an ordinary horseman's spur,
consisting of a base or body a b c d, composed of a fork a band a neck.d, the latter
having at its outer extremity, at the place where in the horseman's spur the knob
or rowel is applied, a bell or jingle e. The sharp spike c is for the purpose of
driving into the shoe heel, in order to afford greater security of fastening.
Fig. 2 is a modification of the spur, the jingle e being here shewn as substituted by
a clapper-bell.
Fig. 3.shews another modification, in which the bell is dish-shaped and is struck
by a hammer f. On its extremity is a sharp point g, so that the spur may also be
used by horseinen.
Fig. 4 shews a variation of the form illustrated in Fig. 3, likewise adapted for
horsemen, the bell carrying at its extremity a small rowel h.
Figs. 5 and 6 shew other forms, wherein the bell or jingle e is provided with
points g, gg, to render it applicable as a rider's spur.
Although the base or body inay be conveniently made in the form of an ordinary
horseman's spur of any usual form, such as box, buckle or screw-spur, this, as above
mentioned, is by no means essential to the invention, since any other form, such as
a spiked plate, single spike, screw or the like, which lends itself to attachment to the
heel, will answer the purpose equally well.
Fig. 7 shows such a modification of the invention, the spur fork of Fig. 1 being here
replaced by a bent plate a, having holes in it, by means of which it may be sewn to
the boot. In this case the neck is shortened, so as to form merely a junction-piece
between the body or plate a and the bell c.
In Fig. 8 the lower part a of the neck forms the base or body, and has a sharp
spike c (which may, if desired, be provided with a screw thread) for insertion in the
heel of the boot.
Fig. 9 shews the jingle e formed as a separate piece from the body and neck d,
and attachable by screwing. The jingle can then be changed for a corresponding
part of another modified form of the invention, or for the head of a horseman's

page_text: spur adapted for the purpose: In Fig. 9 the inale screw i is shewn on the neck d
and the female screw on a short neck d¹ projecting from the jingle e. Fig. 9 shews
the female screw situated internally of the jingle. Or the male screw thread
may be on the jingle and the corresponding female thread on the neck d.
Fig. 10 shews a modification, in which in the base ab there is a slot i to receive
the correspondingly tenon-shaped tongue of the neck d. Or, vice versa, the slot
may be formed in the neck d and the tongue on the base a b.
Fig. 11 shews a form of particularly light execution, especially adapted for cycling
shoes. The body abd is here formed of a sheet of thin metal having three points cl
for insertion into the shoe, and holes to enable it to be stitched to the material of the
.shoe.
Fig. 12 shews the same modification in its bent form ready for application to the
shoe. Instead of the form shewn, the plate may be round, star-shaped, triangular,
rectangular, or of other convenient form, and the number of the points or holes
altered, or one or both altogether dispensed with.
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 alarm or signal apparatus for cyclists, forming at the same time an orna-
mental appendage, consisting of a spur base or its parts or rudiments, or of any other
body or base of a shape suitable for securing to the heel and having formed on it, or
connected to it, a bell or bells or jingles or chime or other aların or signal
mechanism of any shape, the alarm being sounded by the motion of the foot of the
wearer, all substantially as herein described and set forth in the accompanying
drawing.
2. A modification of the alarm or signal apparatus claimed in claim 1, wherein
the alarm mechanism is provided with a point, or points, rowel, knob, or other means
for the purpose of rendering it also applicable as a horseman's spur, all substantially
as herein described and set forth on the accompanying drawing.
3. A form of the apparatus, claimed in claims 1 and 2, in which the base is cut or
stamped out of a metal plate, and having, if desired, flexible turned over points, and
holes for stitching to the shoe, substantially as described and set forth in
Fig. 11 & 12.
4. A form of the apparatus, claimed in claim 1, in which the base and the alarm
mechanisin are formed as two separate parts, connectable at will and exchangeable
with other suitable parts.
