COMPLETE SPECIFICATION.
Improvements in Whistles, especially adapted for Use in connection
with Bioyoles.
We, WILLIAM EDMUNDS CRUMP, Bookkeeper, JOHN THOMAS JACKSON
MARTIN, Trainman, and JOHN HACKBARTH, Merchant, all of Sealy, in the
County of Austin, in the State of Texas, United States of America, 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:-
The invention relates to whistles and more particularly to whistles especially
adapted for use in connection with bicycles.
The object is to provide a simple, and cheap, as well as, ornamental bicycle
whistle of novel and peculiar construction adapted for attachment to the bicycle
and made to sound at pleasure.
A further object is to provide a whistle of improved and peculiar construction
which will be adapted and constructed to sound a single note or a series of notes
properly pitched so that a harmonious and pleasing warning is given and which
can be heard for a long distance off.
བ
Having these objects in view the invention consists of a whistle comprising
certain improved features and novel combinations which will be more fully pointed
out in the following description and appended claims and in the accompanying
drawings, in which,
Figure 1 is a front view showing the improved whistle applied to a portion of an
ordinary bicycle.

Figure 4, a cross-section of the stop taken on line 4-4,
Figure 5, a cross-section of the stop taken on line 5--5,
Figure 6, a cross-section of the stop taken on line 6-6,
Figure 7, a cross-section of the stop taken on line 7-7.
The numeral 1 designates the steering tube, and 2 the handle bar of the bicycle.
At 3 there is shown an elongated whistle which is formed at its lower end into a
bowl 4 provided with a hollow coupling 5, which is bent or curved upwardly into
the shape shown.
The barrel is provided with four barrels or vents 6, 7, 8 and 9. Vents 6 and 7
are located on opposite sides of the barrel, while vents 8 and 9. are also located on
opposite sides of the barrel and are disposed a quadrants distance from the other
two vents. The vent 6 is located at the bottom of the whistle bowl, and vent 7 at
some distance up the barrel. The distance between vents 6 and 7 is slightly
greater than the distance between vents 7 and 8, while the distance between the
vents 7 and 8 is somewhat greater than the distance between vents 8 and 9. The
vents are located at such distances apart that when the whistle is blown a series of
properly pitched notes will be sounded.
The numeral 10 designates my improved stop. This stop is cylindrical being
adapted to snugly fit in the barrel and the bowl of the whistle. The stop is
provided with four chambers 11, 12, 13 and 14. The lower walls of the chambers
are in alignment with the lower edges of the respective vents. The stop is cut.

page_text: away at 15 so that an air passage will be provided leading into chamber 11. The
opposite side of the stop is also flat or cut away as at 16 so that an air passage is
provided which leads into chamber 12. A longitudinally extending cut is made
in the stop as at 17 and this provides an air passage leading into chamber 13.
Diametrically opposite, the stop is cut away as at 18 to provide an air passage that
leads to the uppermost air chamber 14. A pin 19 extends across chamber 14, this
being provided so that the stop can be withdrawn from the whistle barrel or bowl
whenever necessary. The numeral 20 designates an ornamental cap which is
screwed on to the upper end of the barrel. About midway of its length the
whistle is provided with a bracket 23. The numeral 24 designates a clip whose
arms pass through this bracket and which is provided with clamp nuts 25 and 26.
This clamp passes around the steering tube 1 and by means of it the whistle is
held in vertical position on the bicycle as shown in the drawings. The numeral 27
designates an elongated bulb which is connected to the coupling of the whistle by
a flexible tube 27. The numerals 28 and 29 designate the members of a double
clamp which is provided with suitable clamping screws 30. This clamp fastens to
the handle bar 2 and also clamps around the metallic connection between the air
bulb and the flexible tube so that the two latter are held in position.
When the elongated air bulb is squeezed, air is introduced into the whistle and
passes through the vents, so that four properly pitched notes are simultaneously
sounded and a pleasing and yet powerful warning given of the approach of the
bicycle.
It is obvious that the improved whistle could be used in other connections than
with a bicycle, and also that it could be operated by other means than air, as for
instance, steam, and further, that it might be varied in many slight and immaterial
ways without departing from the spirit and scope of the invention. It is not
necessary that a series of vents be used inasmuch as the whistle will properly
operate with one vent. It is to be understood, therefore, that the invention is not
limited to the construction herein shown and described, but comprises and extends
to all such variations as come within the purview of the invention.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
1. In a bicycle whistle, the combination with a barrel provided with a vent, of a
removable stop located in the barrel and provided with an air chamber and air
passage communicating therewith.
2. In a bicycle whistle, the combination with a barrel provided with a vent, of a
removable stop in said barrel and having an air chamber opening out through the
vént, and an air passage in communication with the air chamber, and a cap for the
barrel, said cap being screwed on to the barrel.
3. In a bicycle whistle, the combination with a barrel provided with a series of
vents, of a removable stop located in the barrel and having a series of air passages
in communication with said vents.
4. In a bicycle whistle, the combination with a barrel provided with a series of
vents located in such position that a series of properly pitched notes can be sounded,
of a removable stop located in the barrel and provided with a series of air
chambers opening out through the vents and with individual air passages
communicating with the chambers.
5. In a bicycle whistle, the combination with a barrel provided with a series of
vents located at unequal distances apart, of a removable stop located within the
barrel and provided with a series of chambers opening out through the vents, said
stop being provided with longitudinal cuts so that individual air passages are
provided leading to the respective chambers.
6. In a
bicycle whistle, the combination with a barrel provided with a vent, and
having a conical bowl, of a stop located in the barrel and bowl, said stop being

page_text: provided with an air chamber opening out through the vent, and also being cut
away to provide an air passage leading to said chamber, means for connecting the
whistle to the bicycle, an air bulb and a pipe connection leading to the barrel.
Deted this 20th day of October 1896.
