ILLUMINATED MAGIC WAND
Abstract
A toy in the form of a wand having a handle part and an
extending translucent stem part. Within the handle part is a
battery, a mercury switch and a bulb positioned so that the bulb
can be energized by tilting the wand with the light being
transmitted through the translucent stem to its end. A contact
member extends from the bulb inwardly within the handle. At the
base of the handle is a rotatable knob which can actuate a contact
disc to engage or disengage from the contact member so that the
bulb circuit can be cut off when desired, so that the bulb does not
go on unless it is intended that it should come on.

Description
SUMMARY OF THE INVENTION
The invention is a toy in the form of a wand having a handle and an
extending stem which is translucent. The invention is intended
primarily as a toy or plaything for children. Preferably the entire
wand is made of plastic.
In a preferred form of the invention as disclosed in detail herein,
the handle is a tube of transparent plastic having in it a bulb, a
cartridge type mercury switch, a battery and manually actuated
contact means controlling the bulb circuit. The wand has a stem in
the form of a translucent plastic rod extending from the handle,
the bulb being positioned so that when it is on, the wand is
illuminated by way of light being transmitted through the
translucent rod. The mercury switch is positioned so that the wand
can be tilted to cause the mercury switch to turn on and off thus
turning the bulb and the illumination on and off, these positions
being near the horizontal position of the wand, so that when the
wand is actuated in the typical manner of a magic wand, the
illumination will appear and disappear.
A rotatably knob is provided at the base end of the hollow handle
which actuates a disc type contact which is engagable with an
elongated contact member that extends rearwardly within the hollow
handle from the bulb to the rear part of the handle. Thus, by
simply rotating the knob, the bulb circuit can be cut off to
prevent the illumination from being turned on inadvertently when
not desired.
The primary object of the invention is to provide a novel and
fascinating toy in the form of an illuminatable wand in which
illumination is turned on and off by way of tilting of the wand,
the wand embodying improvements by way of additional manually
operable contacts for interrupting the illuminating circuit.
Another object is to provide improvements wherein the wand is
constructed integrally of plastic having a hollow plastic stem and
a solid plastic rod extending forwardly therefrom with a light
bulb, cartridge type mercury switch, battery, and manually actuated
contacts provided in the hollow handle.
Another object is to particularly improve devices in this category
by way of provision of a contact strip extending rearwardly from
the bulb and cooperable with a rotary type disc contact for
connection and disconnecting the bulb circuit.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now in more detail to the various figures of the
drawings, the wand as shown in FIG. 1 has a tubular clear plastic
handle part 10 from which extends an integral solid rod or stem
part 12, which is also made of clear translucent light transmitting
plastic. The wand may have a tapered part 14 as shown between the
tubular part 10 and part 12, or on the other hand there may be a
square shoulder at this part, the tubular part 10 having an
integral scalloped flange 16 as shown to provide a spacer between
the handle 10 and the stem 12, for ornamental artistic purposes.
Also at the end of the stem 12 preferably there is provided an
ornamental part or configuration which in this particular
embodiment is shown as being in the shape of a star made of the
same plastic material.
The handle part 10 is tubular as stated, having a bore 22 and
within this bore there is provided a small flashlight type bulb 14,
having a base 25; a cylindrical cartridge type mercury switch 26; a
flashlight type battery 28; and spring 30.
Bore 22 has an internal taper 34 as shown where the handle part 10
is joined to stem 12, and the bulb 24 is urged into the conical
bore formed. Formed within the bore 22 inside of the handle 10
adjacent to the part 16, there are equally spaced inwardly
extending ribs 36, 37 and 38, as may be seen in FIG. 6, which serve
to position the bulb 25 and the mercury switch 26. Generally
opposite to the rib 37 is a pair of ribs 40 and 41 which form
between them a guide channel for the end part of 42 of an elongated
contact strip 44, which extends longitudinally within the handle 10
as shown. End part 42 is bent out of the plane of the strip and
forms a contact which engages with the base 25 of the bulb 24.
Mercury switch 26 is a commercially available type, it being a
relatively small, cylindrical unit that is bullet shaped, or dome
shaped, and abutting against and engaging the end contact of the
bulb 25. At its other end it has an extending contact 46 which
engages the end contact 48 of battery 28. The electrodes within the
mercury switch 26 are positioned so that it will be engaged by the
mercury to complete a circuit when the wand is at or near generally
a horizontal position.
Within the end of the tubular handle 10 there is a fitting which is
designated generally by the numeral 54. This fitting is preferably
made of plastic as is the other construction as shown in detail in
FIG. 7. It comprises circular end knob 56 having circumferential
ribs 58. Adjacent to this knob is a disc part 60 having a diameter
to fit snugly into the end of the tubular handle 10. Spaced from
the disc part 60 is another disc 62 having a short extending
projection 64. Between the discs 60 and 62 is stem part 66 and
extending from the disc 62 is a square stem part 70 that extends
into the spring 30 and forms a retainer for the spring. Fitting
against the disc 62 is disc-like contact member 72 having
projecting contact part 74 that is adapted to engage with the
contact part 42 of strip 44. Tubular handle 10 has an arcuate slot
as designated as 80 positioned to have the projection 64 on disc 62
move in it when the part 54 is in position in the end of handle 10.
Between the arcuate slot 80 and the end of the handle 10 there is
axial slot 82 whereby the end part of the handle 10 can be expanded
to allow withdrawal of the part 54, the projection 64 moving out
through the slot 82. The contact strip 44 extends all the way to
the end of the handle 10. At its end it has an outwardly bent tab
86 that engages in a notch 88 at the end of the handle 10 as
shown.
The rear side of the arcuate slot has notches in it as designated
at 90 and 92 to provide two fixed or set positions for the
projection 64 in the arcuate slot which are on and off positions
with respect to the circuit for the bulb 25. As may be seen, in one
position of the end knob 56, the projecting part 74 of contact
member 72 engages with the contact part 42 and in the other
position of the end knob 56, the part 74 of disc contact 72 does
not engage the contact part 42 and the circuit is interrupted. Thus
it is possible for the user or operator whenever desired, simply by
turning the knob 56 to make the circuit inoperative so that bulb 25
would not be inadvertently turned on by reason of the wand being in
a position to close the contacts of mercury switch 26. Contact disc
72 has a square hole in it so that it fits onto the square stem 70
and is held against the disc 62 by the spring 30. As will be
observed, spring 30 also urges the battery and mercury switch
against the bulb 25. Mercury switch 26 is readily removable and is
reversed whereby to change the angular position of tilt at which it
is actuated.
Thus as can be observed the parts are very easy to assemble
manually, and it is equally easy to disassemble them to replace a
battery or other part. To do so does not require the removal of any
screws or other fasteners, yet the assembly is very sturdy and
reliable.
From the foregoing, those skilled in the art will readily
understand the nature and construction of the invention and the
manner in which it achieves and realizes the objectives and
advantages as set forth in the foregoing. The toy wand provided is
a fascinating device having substantial entertainment value. Its
design and construction is such as to provide for maximum ease of
fabrication of parts, use of very inexpensive components and equal
ease of assembly so that desired economy is realized.
The foregoing disclosure is representative of a preferred form of
the invention and is to be interpreted in an illustrative rather
than a limiting sense, the invention to be accorded the full scope
of the claims appended hereto.
