Description

March 6, 1934. M. A. KLEIN FLASH LIGHT BATON Filed Dec. 23, 1931 ATTORNEYS.

Patented Mar. 6, 1934 UNITED STATES ATENT OFFIE it may be pivotally secured to the club when ex- 10 posing the lamp and locked to the club when covering said lamp.

Provision for automatically closing the lamp circuit when the cap is removed to expose the i lamp.

Provision for opening the lamp circuit when the cap is locked over the lamp.

These and other objects are attained in the structure described in the specification and illustrated in the drawing forming a part thereof, in which- Fig. 1 shows an elevation of the stick with parts removed to show the inner structure.

Fig. 2 is an elevation of the upper portion of the baton with parts removed and showing the lamp exposed.

Fig. 3 is a plan view on line 3--3 in Fig. 2.

Fig. 4 shows a detail.

The club of the usual cylindrical contour is provided with a cavity 11 substantially as shown having preferably a recessed portion 11 along which is placed a conducting strip 12. One end of the strip 12 is preferably bent normal to its length so as to form a base 13 resting on the bottom of the cavity and a coil spring 14 is secured to this base portion to insure positive electrical contact therewith. A battery 15 is adapted to fit in the cavity 11 and make electrical contact with the coil spring 14. A lamp 16 is adapted to contact the opposite pole of the battery 15 with one terminal 17. The base 18 has a reflector 19 securely attached thereto and thereby forms the other terminal of the lamp filament circuit. A collar 20 is preferably mounted over the lamp base 18 to prevent displacement of the battery terminal and terminal 17 of the lamp.

The mouth of the cavity 11 is preferably provided with a threaded portion 21 which is adapted to receive an annular member 22 of electrically conducting material which the reflector is adapted to abut. The end of strip 12 is secured to member 21 to make electrical contact therewith and with member 22. The annular member 22 s a pair of diametrically opposite recesses,

A cap 25, preferably of the same material as the baton and of the same contour as will render the batons outward appearance the same as the clubs used presently, is provided with an undercut portion 26. A key member 27 of electrically insulating material issecured to the undercut portion 26 of the cap 25 preferably by means of screws 28. The key member 27 is of circular contour with a pair of diametrically oppositely disposed

projections

29, 29 which are adapted to pass through the opening and

recesses

24, 24 so that a quarter turn of the cap after the key member 27 had passed by the annular member 22, will cause same to lock with that member against upward displacement, at the same time to depress 703 the reflector 19 out of contact with member 22.

Instead of making the cap 25 completely removable, it may prove advisable to provide a permanent attachment therefor, even when the lamp is rendered exposed. To that end, the rim portion for an arc of about 90 degrees is preferably cut out to form a recess 30 substantially as shown in Figs. 3 and 4. A screw 31 is screwed into the cap 25 with its shank portion protruding a distance approximately equal to the combined depth of the undercut 26 and key member 27. The head of the screw 31 is disposed under the member 22 in the recessed portion 29 before member 22 is screwed into the baton 10, and thereby the cap 25 is pivotally attached to the baton 10.

All parts contained within the cavity 11 are rendered readily accessible for removal or replacement by merely unscrewing the annular member 22. The key member 27 on cap 25 is used for the purpose by inserting same into the opening of the annular member with

projections

29, 29 fitting in

recesses

24, 24 respectively, and rotating the cap and hence the annular member until the member is unscrewed.

The operation of the device is as follows:

With the cap 25 secured to the member 22, concentrically therewith, the reflector 19 is kept separated from the member 22, so that the circuit including the reflector 19, lamp 16, battery 15, spring 14, strip 12 and member 22 is open, and the lamp 16 is of course not lighted. To light the lamp 16, the cap 25 is revolved about a fourth of a revolution, until projections 29 align with recesses 24, the cap is raised until the key mem- 1 her 27 is above the member 22 as viewed in Fig.

1, whereupon spring 14 forces the battery 15, lamp l6 and reflector 19 up until the reflector rim contacts member 22 and closes the circuit.

If the cap attachment is used, the screw 31 had moved in the recess 30 as the cap 25 was rotated, and the cap may be swung about the screw 31 as a pivot to expose the lamp 16 and permit light to emanate. It will be noted that in the preferred construction shown, key member 2'7 always bears on the end of the stick 10 while the cap 25 is swung into the lamp exposed position to prevent excessive play of the parts.

It will thus be seen that a simple low cost structure is fully disclosed that is positive and simple in operation; that meets the requirements of practical use and whereby the various objects of the invention are attained. Of course many changes in construction and arrangement of parts can be made without departing from the spirit of the invention. It is therefore intended that all matter contained in the description and drawing shall be interpreted as illustrative and not in a limiting sense, except as hereinafter claimed.

Accordingly what is claimed and desired to secure by Letters Patent is:

1. In a flashlight baton having a cavity therein for receiving a battery, a lamp and a reflector therefor, a conducting member over said reflector and means for closing an electric circuit connecting said battery, lamp, reflector and member, a cap attachable to said member and means for separating an adjoining pair of said elements in said circuit when said cap is mounted on said member to effect opening of the circuit.

2. In a flashlight baton, having a cavity for receiving a battery, a lamp and a reflector, the combination of a detachable annular member mounted over said reflector, and means for closing an electric circuit connecting said battery, lamp, reflector and member, a cap, means for engaging said cap to said member and for moving said reflector from said member to open said circuit when said cap engages said member.

3. In a device of the class described, including a stick having a cavity for receiving a battery, a lamp and a reflector, the combination of an annular member detachably set into said stick over said reflector, means for closing an electric circuit connecting said battery, lamp, reflector and member, a cap and a locking provision on said member for retaining said cap to said member and effecting separation of said reflector and member to open said circuit.
