PATENTEU SW5 4 3.731649 SHEET 2 [1F 2 BATON-FLASHLIGI-IT 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 l 172 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 hilly 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-l 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 l0 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 fore when the forward end of the switch member en-' gages 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 l0, 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 thebalance 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 8-2 in accordance with the invention. The instrument 8-2 is precisely identical to instrument B-l 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 l0 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 l-V4 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.
