PROVISIONAL SPECIFICATION.
A Device for enabling Cyclists while Riding their Machines to
Protect Themselves from the Attacks of Dogs.
I, SELIG FRANKEN Jr., of 135º, Weerdjesstraat, Arnhem, in the Kingdom of
Holland, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a device for enabling cyclists while riding their
machines to protect themselves from the attacks of dogs.
The device consists of a small metal cylinder furnished with means for attaching
it to the machine,and provided with metal pipes (four being a convenient number)
which branch out laterally near the chain-wheel on the pedal-shaft. Within the
cylinder there is arranged a spring-controlled rod or plunger. On the top a filling
cap or lid is placed. To the upper part of the rod are secured two hollow tubes
both of which pass through a clamp attached to the frame of the machine near
the seat-pillar. The ends of the tubes are connected by a wooden knob or handle.
The filling lid is first unscrewed, and some pepper is poured into the device.
The lid is then replaced and tightened, whereupon the device is ready for use.
For pepper, some other pulverulent material, noxicus to dogs but comparatively
harmless, may be substituted.
Should a dog come near the machine, it is only necessary for the cyclist to
depress the knob or handle, sufficient pepper being thus expelled from the device
through the metal pipes near the chain-wheel to drive the dog away.
The complete device does not add much to the weight of the machine, while on
account of its shape it offers little resistance to the wind.

A Device for enabling Cyclists while Riding their Machines to
Protect Themselves from the Attacks of Dogs.
1, SELIG FRANKEN Jr., of 135c, Weerdjesstraat, Arnhem, in the Kingdom of
Holland, 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 a device for enabling cyclists, while riding their
machines, to protect themselves from the attacks of dogs.
In the accompanying drawings,
Fig. 1 represents in vertical section one form of apparatus adapted for carrying
my invention into effect.
Fig. 2 is a corresponding side elevation, and Fig. 3 a plan.
Fig. 4 is a vertical section, and Fig. 5 a plan of a modified construction.
Fig. 6 is a side elevation of a "safety" bicycle illustrating (by way of example)
the mode of applying my invention.

page_text: According to one mode of carrying out my invention, the device consists of
a small metal cylinder a secured to the frame of the machine by means of brackets
or supports b, b', and provided on each side with a chamber c, c', from which the
distributing pipes d d, d'd' branch out laterally near the chain-wheel on the pedal-
shaft. Within the cylinder there is arranged a spring-controlled rod or plunger e
which operates a bellows or collapsible chamber e. Through the plunger is
formed a filling bole f, which is closed by a screwed cap or stopper fl. On the
outer face of the plunger e are secured two rods or hollow tubes g g, both of which
pass upwards and through a clamp or guide h attached to the frame of the machine
near the seat-pillar. The upper extremities of the rods or tubes may be connected
by a wooden knob or bandle, or they may be formed from a single rod or tube and
be simply arched as shown at i in order to afford ready means for operating.
Upon depressing the plunger e, a portion of the pepper contained in the collapsible
chamber e¹ will be forced through the passages e* into the chambers c c¹ and thence
through the pipes d d'.
According to the construction illustrated in Figs. 4 and 5, the cylinder a is
surrounded by a chamber cx, from which the distributing pipes d d' project. In
this arrangement, the collapsible chamber e¹ is supplied with air through the
opening at k, a valve k' being provided for admitting air during the upward
movement of the plunger. f' is a cap or stopper for closing the filling hole in
the top or cover of the chamber c*. Upon depressing the plunger e, air is forced
from the collapsible chamber e¹, by way of the passages 11, through the
perforations in the bottom of the chamber c*; a small quantity of the pepper or
other material in the said chamber c* being blown out through the distributing
pipes d d¹.
In preparing the apparatus, the cap f¹is first unscrewed, and some pepper is
poured into the chamber e' or c* (as the case may be). The cap is then replaced
and tightened, whereupon the device is ready for use. For pepper, some other
pulverulent material, noxious to dogs but comparatively harmless, may be
substituted.
Should a dog come near the machine, it is only necessary for the cyclist to
depress the plunger e through the medium of the handle i; sufficient pepper being
thus expelled from the device through the pipes d d' near the chain-wheel to drive
the dog away.
The complete device does not add much to the weight of the machine, while on
account of its shape it offers little resistance to the wind.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I claim
---
1. The improved means for enabling cyclists, while riding their machines, to
protect themselves from the attacks of dogs, arranged or operating substantially as
described with reference to the accompanying drawings.
-2. In apparatus of the character herein referred to for affording protection to
cyclists, the employment of a plunger, and a pepper chamber in conjunction with
distributing pipes, arranged and operating substantially as described with reference
to Figs. 1 to 3 of the accompanying drawings.
3. In apparatus of the character herein referred to for affording protection to
cyclists, the employment of a plunger, pepper chamber and distributing pipes,
arranged and operating substantially as described with reference to Figs. 4 and 5
of the accompanying drawings.
