Description
BACKGROUND OF THE INVENTION
It has heretofore been known to manufacture flashlights of very
rugged construction so that they may, for example, be
advantageously used in police work. Heavy duty flashlights of this
type have heretofore been manufactured by Kel-Lite Industries, Inc.
of 1172 East Edna Place, Covina, California, with which the
applicants herein have been associated.
The present invention, however, provides an extension in both
theory and practice with regard to previously known types of
flashlights. The present invention provides an instrument which
functions as a baton or billy-club as well as a flashlight. The
instrument is particularly well adapted to police work, inasmuch as
the policeman can hold the instrument in his hand and use it as a
flashlight for viewing purposes, and upon perceiving a need for the
use of a billy club or baton he may immediately proceed to use the
same instrument in that fashion without having to stop to exchange
one instrument for another and without even having to take the time
to turn off the switch that controls the illumination.
According to the present invention a hollow, cylindrical, metal
housing, or barrel, is utilized which has a total length
considerably greater than the length of a series of batteries which
will supply the energy for illumination purposes. The interior of
the housing or barrel is partially filled with the battery train,
but in addition thereto an elongated metallic spacer block is
inserted inside the barrel in series with the battery train. The
spacer block and the battery train are electrically connected
together, so that the current for the illumination flows through
both of them in series. Furthermore, when the instrument is wielded
as a baton, the spacer block provides both weight and balance which
are needed for optimum performance of the baton.
It is, therefore, the object and purpose of the present invention
to provide a composite instrument which will function effectively
both as a billy-club or baton and also as a flashlight.

PREFERRED EMBODIMENT
Reference is now made to FIGS. 1 through 4, inclusive, illustrating
the presently preferred embodiment of the invention. A
baton-flashlight B-1 includes an elongated, hollow, matallic
housing or barrel 10, whose length is at least ten times its
outside diameter. A forward assembly 20 is attached at one end of
the housing or barrel 10, and a metallic rear end cap 40 is
removably attached at the other end.
Contained within the housing or barrel is a battery train 30, which
in the particular illustration includes batteries 31, 32, 33, 34
and 35. Since it is desired to have the instrument relatively long
and narrow, these batteries are preferably of the C size. Also
contained within the housing or barrel 10 is a metallic spacer
block 50. The spacer block 50 is preferably a solid, cylindrical
block made of aluminum. It has the same outside diameter as the
batteries and has a length which is equal to the length of several
of the batteries. The spacer block and the battery train are placed
in series so that the electrical current flows through both of them
serially.
As shown in FIG. 2b the rear end cap 40 is threaded for removable
engagement with the rearward end of the housing or barrel 10. End
cap 40 also has a recess which receives a spring 41, which engages
the rearward end of spacer block 50 so as to provide electrical
conduction between the spacer block 50 and the end cap 40. An
exploded view of the same parts is shown in FIG. 4.
The construction of forward assembly 20 is best illustrated in FIG.
2a. An enlarged metallic head 21 has threads for removable
engagement with the forward end of the housing or barrel 10. A
circular, rubber gasket 25 is fitted on the forward end of the head
21. A lamp and reflector assembly 23, made as an integral unit, is
disposed inside the head 21, and at the forward and outer extremity
of the reflector there is a supporting flange which engages an
annular groove in the gasket 25 and is retained in position
thereby. A circular lens 24 fits over the forward end of gasket 25.
A circular face cap 22 is screwed on to the forward end of head 21
and hence holds the gasket 25 and lens 24 in place.
The rearward and smaller end of the lamp and reflector assembly 23
contains a bulb and bulb socket, not shown in detail, and these are
surrounded by a rubber shock absorber 26. A first contact 27
protruding from the bottom of the socket (shown in FIG. 2a in
dotted lines) is engaged by the forward end of battery 31 so as to
provide an electrical connection therebetween.
The outer metallic surface 28 of the reflector bowl provides a
second terminal for the lamp or bulb means, and may be selectively
engaged by the forward end of the switching member 62.
Switch means 60 is located on the housing or barrel 10, adjacent
the forward assembly 20. The switch means 60 includes a switch cap
61 which for the most part is located external to the housing or
barrel 10, although a small central portion of it protrudes into an
opening that is cut in the barrel for that purpose. Switch member
62 is an elongated copper strip which is disposed inside the
housing or barrel 10 and occupies the space between the side wall
of batteries 31, 32 and the inner side wall of the housing. As
previously mentioned, the end of switch member 62 also extends up
into the interior of the head 21 where it is able to selectively
engage the reflector surface 28. A small bolt 63 and nut 64 are
used to fasten the switch member to the switch cap. Switch cap 61
is made of rubber or other insulating material. Switch cap 61 has a
rearward or retracted position in which the flashlight is not on.
It also has a forward position in which the flashlight is turned
on. A small detent 62a is formed on the switch member 62, for
engaging one or the other of two different openings in the housing,
in order to hold the switch in whichever position the user has
placed it in.
Switch member 62 is held in firm sliding contact with the interior
wall of the housing or barrel 10, and therefore when the forward
end of the switch member engages the reflector bowl, the circuit
through the lamp or bulb means is completed.
It should be pointed out that in accordance with our invention the
metal spacer block may, if desired, be interchanged with the
batteries, putting the spacer block at the forward end of the
barrel and the batteries at the rearward end. Alternatively, the
batteries may be divided up, putting the spacer in the middle of
the barrel and some of the batteries at each end.
It should also be pointed out that in accordance with the invention
the weight of the spacer may be selected in order to optimize the
characteristics of the instrument as a billy-club or baton. We
presently prefer to make face cap 22 of stainless steel, while the
barrel 10, end cap 40, head 21, and spacer block 50 are preferably
made of aluminum.
Thus, it will be seen that when the flashlight is turned on the
current flows through the battery train into one terminal of the
lamp or bulb means, thence through the lamp or bulb means and out
its other terminal through the switch member 62, thence into the
forward end wall of the housing or barrel 10, thence throughout the
full length of the housing or barrel 10, thence to the rear end cap
40, thence through the spring 41 then to the rearward end of the
spacer block 50, thence through the full length of the spacer block
50, and then to the rearward end of the battery train. The spacer
block 50, therefore, serves to conduct electrical current when the
instrument is operating as a flashlight, and it also serves to
provide a desired amount of mechanical weight (hence improving the
balance of the instrument) when the instrument is to be used as a
billy-club or baton.
ALTERNATE FORM
Reference is now made to FIGS. 5, 6 and 7 illustrating a modified
instrument B-2 in accordance with the invention. The instrument B-2
is precisely identical to instrument B-1 except for the addition of
a support ring 70. Support ring 70 is preferably made from a
malleable material such as rubber or neoprene. It is then
positioned near the forward end of the serrated surface 11 of the
housing 10, only a short distance rearwardly of the switch cap 61.
This, then, makes it possible to conveniently suspend the
instrument from the belt of a wearer by using the holding strap 71
in conjunction with its holding ring 72, the ring 72 slipping over
the rear end cap 40 and most of the length of the housing 10 and
holding the instrument from the under side of the support ring
70.
PREFERRED DIMENSIONS
According to the illustrated form of the invention the barrel 10
has an outer diameter of about 1-1/4 inch and a length of about 14
inches, five C batteries are used, and spacer block 50 is about 4
inches long. According to a second form of the invention barrel 10
has the same diameter and is about 22 inches long, seven C
batteries are used, and spacer block 50 is about 8 inches long.
As will be understood by those skilled in the art, what has been
described are preferred embodiments in which modifications and
changes may be made without departing from the spirit and scope of
the accompanying claims.
