COMBINED BLOW GUN AND DARTS
Abstract
A combined blow gun and darts wherein the blow gun includes a
substantially elongated tubular member, a mouthpiece mounted on the
end of the tubular member, a plurality of magnets secured to the
tubular member in proximity of the mouthpiece and a plurality of
darts held in position on the gun by the magnets, and wherein each
of the darts consists of a cylindrical body section whose diameter
is substantially slightly smaller than the inner diameter of the
tubular member for free sliding movement of the dart through the
tubular member, a pointed metallic rod mounted at the axis of the
cylindrical body section and extending forwardly thereof, and the
forward peripheral edge portion of the cylindrical body section
being slotted to stabilize the dart while in flight.

Claims
What I claim as new and desire to secure by Letters Patent of the
United States is:
1. A combined blow gun and darts comprising an elongated tubular
member having a mouthpiece at one end, a plurality of magnets
secured to the outer surface of said tubular member, one of said
magnets being in proximity of said mouthpiece, a plurality of
darts, each dart having a cylindrical body member and a pointed
steel rod extending forwardly of said body member at its axis, said
dart having slotted portions extending longitudinally from its
forward edge portion on the surface of said cylindrical body member
and a steel rod extending forwardly of said body member along its
axis.
2. The structure as recited by claim 1 wherein said magnet
positioned in proximity of said mouthpiece is of sufficient
strength to magnetically attract a dart placed partially in the
tubular member whereby said dart is permitted to tilt with said
steel rod extending in a direction of said last named magnet to
hold said dart in position in said dart gun.
3. The structure as recited in claim 2 wherein said slotted
portions terminate in spaced relation to the rearward edge portion
of said body member.
4. The structure as recited by claim 3 wherein said mouthpiece is
provided with a flared free end portion for receiving the lips of a
user.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates directly to blow guns.
2. Description of the Prior Art
There has been little advancement of the art of blow guns for many
centuries since its advent before the discovery of gun powder. The
blow guns used by natives consist of a hollow reed with a dart that
was stabilized in flight by feathers attached to the body portion
of the dart. In recent years, improvements made to the ancient blow
gun consisted of replacing the hollow reed with a tubular member
and the feathers on the dart by a solid body member. However, the
dart gun still remained inaccurate in its shooting ability and
inefficient in converting lung power to propulsion of the dart. The
present dart guns are very inefficient as there is a considerable
loss of propulsion power, which at its best is limited, due to the
use of feathers or ill fitting darts. In addition, the darts have a
tendency to either tumble or stray from their line of flight
because of a lack of an effective means of stabilizing the dart in
its flight.
SUMMARY OF THE INVENTION
The present invention contemplates among its objects to provide a
combined blow gun and darts which permits the blowing of the dart
out of the blow gun at a high velocity and compelling the dart to
maintain a substantially straight or true path toward its
target.
Another object of the present invention is to provide a combined
blow gun and darts with magnets mounted on the blow gun for
maintaining darts in position on the gun accessible for use by gun
users or for storing purposes.
A further object of the present invention is to provide a dart with
a cylindrical body portion made of wood, plastic and the like with
serrations or grooves formed about its periphery at the forward
edge portion thereof to provide a stabilization effect to the dart
while in flight.
With these and other objects in view, the invention will be best
understood from a consideration of the following detailed
description taken in connection with the accompanying drawing
forming a part of this specification, with the understanding,
however, that the invention is not confined to any strict
conformity with the showing of the drawing but may be changed or
modified so long as such changes or modifications mark no material
departure from the salient features of the invention as expressed
in the appended claims.
BRIEF DESCRIPTION OF THE DRAWING
FIG. 1 is a side elevational view of my combined blow gun and darts
partially broken away at the mouthpiece showing darts in position
thereon with the dotted line showing the dart in the mouthpiece
when ready for being blown from the gun.
FIG. 2 is a similar view showing the flight of the dart as it moves
through the blow gun.
FIGS. 3 and 4 are cross sectional views taken along the lines 3--3
and 4--4 respectively of FIG. 1.
FIGS. 5, 6 and 7 are cross sectional views taken along the lines
5--5, 6--6 and 7--7 of FIG. 2.
FIG. 8 is a perspective view of my blow gun with the mouthpiece
partially cut away.
FIG. 9 is a perspective view of a dart.
Referring to the drawing wherein like numerals are used to
designate similar parts throughout the several views, the numeral
10 refers to a blow or dart gun constructed in accordance with my
invention and the numeral 11 referring to my improved darts. The
blow gun 10 consists of an elongated tubular member 12, preferably
made of aluminum and having a constant and even bore 13 along its
full length. At one end there is mounted a mouthpiece 14 consisting
of a small section of a tubular member fitted over the end portion
of the tubular member 12 and having an outwardly flared end portion
15 for accommodating a person's lips as the user places his mouth
there against for blowing the dart 11 at a target.
Mounted on the outer surface of the tubular member is a plurality
of magnets 20 glued or otherwise secured thereto. One of the
magnets 20 is placed in the vicinity of the mouthpiece at a
distance about equal to the length of a dart. The function of the
magnets 20 is to secure in position on and in the tubular member 12
a plurality of darts 11 accessible to the user of the blow gun 10.
The magnets also serve to store the darts 11 so that the latter
cannot become separated from the gun 10 nor become lost.
The dart 11 is provided with a body portion 21 of cylindrical shape
and made of wood, plastic and the like. The diameter of the body
portion 21 is such that it fits snugly yet loosely without binding
in the tubular member 12. The forward edge portion 23 of body
portion 21 is provided with a plurality of slots or grooves 22 that
extend longitudinally along the outer surface from the forward edge
of the body portion 21 for a distance of about one-third of the
total length of the body portion 21. These grooves 21 compel the
darts 11 to revolve within the tubular member 12 as they are being
blown therethrough to provide stability to the flight of the dart
while in free flight toward the target. Extending from the forward
end portion 23 of the body portion 21 at its axis is a rod 24,
pointed at its free end 25 for penetrating a target. The rod is
preferably made of steel that is attracted by the magnets 20 for
maintaining the darts 11 in position on the blow 10 gun as shown by
FIG. 1.
In the normal use of my blow gun 10, the darts 11 are placed on and
in the blow gun adjacent to the magnets 20 with the steel rods 24
of the darts adjacent the magnets 20 whose attraction maintain the
darts 11 in position thereon. The dart 11 which is in the barrel 13
of the blow gun 10 as shown by FIG. 1 with that dart 11 inserted
only partially within the mouthpiece 14 to permit the dart 11 to
tilt and the steel rod 24 to swing toward the magnet 20 due to the
magnetic attraction of the magnet 20 whereby the dart 11 is held in
position at the mouthpiece 14 of the dart gun 10. When it is
desired to fire the dart 11, the user pushes the dart 11 inwardly,
that is at the mouthpiece 14, to cause the dart 11 to center itself
in the tubular member 12 and assume the position shown by the
dotted lines in FIG. 1. Now by placing his lips at the flared end
15 of the mouthpiece 14 and blowing therethrough, the dart 11 will
be propelled through the tubular member 12 and rotates as it
emerges from the blow gun to fly at a high rate of speed in a true
flight to the target.
