Referring in detail to the drawing, 20 denotes a wrist carrying flashlight incorporating a selector portion to manually change the projecting light beam as and for the purpose described to embody the invention.

Said wrist carrying flashlight 20 may comprise a suitable outer casing 21, here shown as being a one-piece molded plastic box 21a formed with a bottom open side. Said box 21a normally is fitted in a reverse upstanding position with said open side against a base closure or undercap 21b and may be secured in closed position by any suitable fastening means, as for example, by screw 21c passing through the base closure 21b countersunk to engage head 21d of screw 210. A threaded end 21a of the latter is removably secured in a boss 21 integrally formed to extend down from upfacing wall 21g of casing 21, as is clear from Figs. 3 and 4. i

In said box 21a, there may be assembled a standard electric dry cell battery 22 of the short miniature type, a double contact incandescent lamp 23 and a suitable switch button 24. for making and breaking a portion of the circuit passing from one terminal 22:: of the battery 22, shown in Fig. 3 as the carbon electrode, to switch contact end 25a of a current carrying spring'jumper 25. The other contact end 25b of said jumper 25 is constructed and arranged to spring press against ferrule lamp' base contact 23a of lamp 23. There is also provided as part of the circuit a current carrying spring jumper 26 which pressure connects the other end terminal 22b of battery 22, here shown as the zinc electrode, with center contact 23b of lamp 23.

Battery carbon electrode terminal 22a may be positioned in the assembly as shown in Fig. 3 so that the axis length of lamp 23 extends in a relatively right angular relation with respect to the length of cell 22 adjacent a mid-portion of the latter, said battery terminal 22a projecting to close the circuit through spring jumper contact end 25a when flexed from fullline position, open circuit, todotted line circuit energizing position on pressing control switch button 24.

The assembly of the battery cell 22, lamp 23 and switch 24 with the

interconnecting jumpers

25 and 26 mounted in casing 21, as above described, and having a suitable wrist band or'strap 36 engaging base box closure 21b in the manner shown in Figs. 1, 2, 4 and 5, provide an arrangement contributing to features of the invention for use particularly in wrist borne flashlight 20.

As is clear from Fig. 4, battery cell 22, lamp 23, switch 24,

spring jumpers

25 and 26 form a circuit con-' struction of removable and replaceable parts. Cell 22 may be retained in operative position by suitably spaced apart abutment ledges 27 and 28 and an angle ledge 29 aligning therewith and spaced from ledge 27 a distance to permit fitting cell 22 therebetween with the battery carbon electrode 22a extending therebeyond toward switch contact end 25a. Oppositely positioned with respect to ledge. 28 and spaced from angle ledge 29, there may be provided an H-shaped ledge 30 which, with ,a mid-portion 26a of jumper 26 mounted thereagainst, aligns with said ledge 29. Another H-shaped ledge 31 similar to ledge 30 may be provided for mounting a midportion 250 of jumper25 spaced from angle ledge 29 and H-shaped'ledge 30. Said ledges 27, 28,29, 30 and- 31 may be integrally formed to extend from the inner surface of easing box upfacing wall 21g. 7

As seen from Figs. '3 and 4, incandescent lamp 23, which may be of the standard miniature. flashlight type having a lenstipped bulb.23 c, beside the base ferrule contact 23b, is retained in said right angular position with respect to cell 22 between short and relatively long L- shaped spaced apart ledges 32 and 33, respectively, which may be integrally formed to extend down from the'inner surface of said upfacing-Wall 21g. Said ledges 32" and 33 form a stall therebetween into which'said lamp 23 'fits'with the lens tipped bulb Z3c extending therebeyond to give maximum spring contacting pressure and to fa-- cilitate servicing and maintenance. A contact end 26c bent at right angles from said jumper mid-portion 2 6a opposite said-end 26b may be provided disposed to electrically connect with the battery zinc terminal as at 22b,

said contact end 260 having a punched tongue portion 26c bent therefrom to serve as a scraping means made effective on pressing the switch button '24 when energizing the circuit in the manner hereinafter described.

For'retaining said

jumpers

25 and 26 in proper operating position in the assembly, the mid-portion 25c and 26a, respectively, of said

jumpers

25 and 26, may be formed with

spring clip portions

25d and 26d, respectively. Said spring clip portions, as is clear from Figs. 3, 5, 12 and 13, form attachment means which securely anchor said jumper mid-portions 25c and 26a to H-shaped

ledges

31 and 30, respectively. 7

Where means for changing the projected light'beam color is incorporated in the construction of flashlight 20, a suitable strip light filter screen 34 may be provided as here'shown in Figs. 1, 3, 4, 7, 9, 10 and 11, and when casing 21 is circular in cross section, said filter screen 34 may be made to have an elongated arcuate shape formed with a series of'transparent colored and clear sections, as for example, red, colorless or an opening, and blue sections 34a, 34b and 340, respectively, Said filter screen 34 may be mounted for sliding movement infconcentric relation in close proximity with said box side wall 21k.

'To direct filter screen 34 in sliding movement in a circular path, there may be provided guide abutment ledges 35 spaced apart and integrally formed to extend down from the inner surface of said upfacing wall 21g. And for shifting the filter screen 34 when selectively changing the color of the light beam from lamp 23 projected through casing box opening 21h, said screen 34 may be formed with an edge extension portion 34d'which passes through an elongated arcuate slot 2'1j provided in the upfacing wall 21g of easing box 21a. Said extension portion 34d terminates in a finger piece 34s on the exterior side of said wall 21g, as is clear from Figs. 1, 1O and'll. It is to be noted that when filter screen 34 has two colored filter sections separated by a clear section, finger piece 342 for simplicity of flashlight operation may be positioned along the slot 21j in the region of switch pushbutton 24, the latter extending through an opening 21s inthe curved side wall 21k and in order that the'inner actuating head .end 24a of switchpush-button 24 be kept free frominterference in movement thereof-to flex jumpbe cut away or slotted at 34 for a length thereof as required and as is clear from Figs. 7, l0 and 11.

Bandorstrap 36 may be of any conventionalmake saidpassageway through spaced apart aligning slots 21n er end 25a when closing the circuit, filter screen 34 may 7 a formed along opposite edges of said mid-portion 21m, as is clear from Figs. 2, 4 and 5.

For seating the casing box 21a in said reverse upstanding position on base closure 21b, said exterior wall of the latter may be made with an integral edge flange 21p within which the box side wall 21k neatly fits. a

To facilitate ready assembly of the parts of flashlight 20 and to provide a construction that lends itself to form aesthetic appealing designs that are attractive, exterior side of casing upfacing wall 21g may be made with a trim element 21g which may project down to extend along the box side wall 21k and replace portion of flange 21p to form a reflector frame 21;- about said Wall opening 21h wherethrough light beams are projected from lamp 23.

The practical utility of the invention will now be apparent. After providing the various parts as hereinbefore described and shown in the drawings, the casing box 21a through said open bottom side thereof may be readily assembled with those parts housed therein as shown in Fig. 3 by first'inserting head 24a of switch button 24 to extend freely through filter screen slot 34 Filter screen 34 may then be positioned in casing box 21a so that extension 34 1 extends through slot 21 and switch button 24 is seated in opening 21s. As is clear from Figs. 3 and 7, opening 21s is in the form of a slot having an open end extending through the edge of side wall 21k. Finger piece'34e may now be aflixed to. terminate said edge extension 34d so that said finger piece 34a canbe operated from the exterior side of wall 21g,

the portion of filter screen 34 carrying colored and clear sections being positioned to slide between spaced apart guide abutment ledges 35 and circular side wall 21k.

Next, the current carrying

jumpers

25 and 26 may be mounted in operative position by anchoring

spring clip portions

25d and 26d, respectively, on H-

shaped ledges

31 and 30. With said

jumpers

25 and 26 secured in place, lamp 23 may then be slipped in the stall formed by said

ledges

32 and 33 with the lens tipped bulb 23c facing said wall opening 21h and with ferrule and center contacts 23a and 23b, respectively, being electrically connected in circuit with jumper ends 25b and 26b,'respectively. The battery cell 22 may also he slipped in position ready to energize the circuit on pressing the'switch button 24 by inserting said cell 22 so as to be confined between said ledges 27, 28, 29 and jumper end 260 which electrically contacts the battery terminal zinc electrode 22b. The carbon electrode battery terminal 22a will then be in a normal 0 circuit switching position in close proximitybut not contacting jumper end 25a. All parts thus assembled'will be mounted and connected in circuit as shown in Fig. 31 V i Base closure 2112 may then 'be fitted with said strap or. band 36 by threading the latter into the passageway behind said wall mid-portion 21m and through said edge slots 21n. Base closure 21b is then fitted as an undercover for casing box 21a 'and'retains all partsin operative position in the latter. Edge flange 21p, as seen in Fig.7, is effective to close the open end of slot opening 213 for retaining switch button 24in operative position, button head 24a being enlarged along a diameter thereof .to prevent passage through opening 215, as is clear from Fig. 3. 7

Finally, fastener screw 210" is inserted to engage boss 211 to retain the assembly together as a complete flashlight 2 6. By 'simplyrem'oving screw 21c and dismounting bas'e closure 21b, the entire contents of the casing box 21a is fully exposed for servicing and maintenance.

The completed flashlight 20 may be supported and secured by means of the band 36 and buckle 36a and, as is 7 clear from Figsfl and 2, when wrist borne, c'ar1 readily be directed for space illumination ors'ignalingby' simply pressingswitch button 24 to close the circuit byflexing jumper end 25a to contact the battery carbon terminal 22a. It'sho'uld be noted that pressure contact exterted on closing the circuit depresses jumper end 25a and tends to move the battery cell 22 with zinc terminal 22b thereof against the scraping tongue 26e of the jumper end 260 assuring good electrical contact thereat.

To change the color of the projecting light beam, the finger piece 342 is moved to selectively bring either red filter screen section 34a, clear 34b or blue 34c to cover casing box opening 21h and reflector frame 21r.

By positioning wall opening 21h in alignment with respect to the longitudinal plane of wrist band 36, that is, at 12 oclock, and positioning switch button 24 at 90 degrees thereto or at 3 oclock as shown in Figs. 1 and 2, flashlight 20, when worn on the left wrist, will transmit light beams normal to the wrist axis. When the left wrist bearing flashlight is held in a pronated position, the right finger may readily be used to operate switch button 24 and finger piece 34e.

It is thus seen that there is provided an improved wrist carrying signal light construction whereby the several objects of this invention are achieved and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matters herein set forth or shown in the accompanying drawings are to be interpreted as illustrative and not in a limiting sense.
