n ELECTRIC TRUNCHEON TORCH.

Application led. April 2K5, k1925, Serial No. 25,878, and in Australia November 5, 1924.

My invention relat-es to improvements in an electric truncheon torch the object of which is to provide police and those engaged in a like lawful capacity by night with an in-y strument ot' searchv and a reliable means of defence in' which the constructionhas been f so arranged thatl on being usedftor the latter purpose the only damage likely to befall the instrument would be the breaking lo of the filament of the electric light bulb and to meet this contingency extreme accessibility and the most rapid method of disassembling and `1re-assembling has been employed. For instance in Figs. land 2 three movements of the mechanism suiiice to yexpose allfthe interior working parts whilst in Fig. 10 a simi lar object is achieved by two operations. A

further objecty of converting the invention for use as an ordinary police truncheon is attained by withdrawing the innerpartsrequired for lighting purposes and replacing them by a dummyof some suitable material.

I attain theseobjects by the mechanism il-y lustrated in the accompanying drawings.

Similar numerals, and numerals with letters, reiter to similarparts throughoutl the several views.

18 is theha'ndle of wood or other material having atety strap 14 for the wrist of the 2 In'th'e interior ot the tu-r end a lamp screw socket 19 and lamp reflector'r f 20. In the lamp socket 19 is anelectric lamp 21 situated behind 'theprojector lens 22 `formed on one end of the tubular casing 15.` An yalternative projector lens may. be attachedl by means of a screwedsocket 22 screwed into the outer end ofthe tubular casingl as shown in Fig. GL Attached to the lopposite end ofthek electric battery conductor cageklS isy a butler contact .spring 9.4 having a contact plate Q5. A switch press button Q6 with angularly disposedpress pin 2T attached thereto is adapted to impinge against thecontact plate 25 attached `to thebniifer contact spring 24 to compress the latter thereby making electric contact with one poleor carbon .28 ofthe battery 17 the circuit being thus completed to light thelamp 21, t-he current passing by vwayoi contact plate 25, butferspring Q11-,battery conductor cage 18, reflector 20, lamp rscrew socket 19,lamp 21 thencereturning through insulated contact 29 tothe other pole orzinc of battery 17. yIn Fig. 5 is shown an alternative method of applying the buii'er contact spring 24E the latter being attached to a secondary spiral butter spring 30 by means eta socket joint 31. The handle `13 is removably attached to thetubular casing 15 by means ot iii:

thesplit ring 32 the latter having firmly attac-hed thereto the pins (one or more) 33, the Saidpins 33 passing through oppositely bored holes in thetubular casing 15 andmetal ferrule 34 attached to shoulder ofhandle 13.

In Fig. 6 is shown an alternative method of attaching thehandle 13 to thetubular casing 15 where themetal ferrule 34 is internally threaded to lit external threads cut on thektubular casing 15. Fig. 7 is a further alternative of F 6 of attaching thehandleV 13 to thetubular casing 15 wherQ the metal ferrulec34 on thehandle 13 is externally threaded to fit theinternal threads cut on inside of thetubular casing 15. 1n Figs. 3 and 9 bayonet sockets are alternatively adapted to Vremovably attach thehandle 13 totubular casing 15, where in Fig. 8 themetal ferrule 34 of thehandle 13 is tted to slide internally intotubular casing 15 and isprovidedrwith pins 35 to fit and engage theslots 36 and is also adapted to fit and slide externally over thetubular casing 15 land engage thepins 35 provided in the latter. y A further alternative of removably attaching thehandle 13 totubular casing 15 is shown in Fig. 10 where set pins 37 attach firmly to presssprings 33 which lat-ter are secured by screws at one end to Vthe handle 13, the pins 37.1Jassing outwardlyT through themetal ferrule 34 andtubular casing 15 which lock thehandle 13 andtubular casing 15 firmly in position. By depressing thepress springs 33 into the slots 39inthe handle 13 the set pins 37. are disengaged from the holes in theferrule 34 andtubular casing 15 when thehandle 13 may be readily withdrawn. An alternative method of applying an electric press button to thehandle 13 is shown in Fig. 11 where thepress pin 27 provided with apress button 26 arranged to slide in a hole bored centrally and horizontally through thehandle 13. In Fig. l2 is an alternative method of using a Vhollowmetal handle 40 havingpress button 26 and an angularly disposed press pin 2'?, the latter having a hingedjoint 41 attached to a sliding pin 42 sliding in aguide tube 43 attached to the end cap` 44 allowing free play of the angularlyV disposed pin when the latk ter is depressed by thepress button 26. A further alternative method of attaching thehandle 13 to thetubular casing 15 as shown in Fig. 13A, is effected by a threadedunion 45 withflange 46 held ontubular casing 15 by circumferentially arranged stud pins 47, or shoulder, ontubular casing 15 fitted to screw on to corresponding' thread on outside offerrule 34 ofhandle 13. VFig. 14B, shows a reversal of the action in Fig. 13A, inasmuch as threadedunion 45 withflange 46 is held onferrule 34 ofhandle 13 by circumferentially arranged stud pins 47, or shoulder, on

ferrule 34, fitted to screw on to corresponding thread on outside oftubular casing 15. Fig. 15C, shows a sectional perspective view of attaching thehandle 13 `to tubular casing l'by screwed fiange and union with pins abutting flange as illustrated in Figs. 13A, and 14B. Fig. 16D, is a modication of Fig. 2 inasmuch as the action therein is reversed byferrule 34 ofhandle 13 being constructed vto fit overtubular casing 15 4instead of in the interior thereof. As a further alternative Athehandle 13 may be made a fixture intubular casing 15 by constructinghandle 13 andtubular casing 15, in one. piece, or affixing thehandle 13`in thetubular casing 15 by screws and the Vinterior of the latter rendered accessible by removing screw cap offlange 22 Fig. 6, and the tubular casing left uncovered, and filled with a dummy filling of somesuitable material 48 as shown in Fig. 17E, or covered as already described.

l prefer to carry out the features of my invention as embodied in Figs. 1, 2, 3, 4, 5, 10, 12, 16D, and 17E.

I am aware that prior to my invention im proveniente have been made iny elect-ric torches, I, therefore, do not claim such improvements broadly, but l claim 1. Atruncheon torch comprising a weighted hollow body, a detachable handle for said body, a removable electric battery and refleeting lamp within said body, a light projector lens associated `with said body and lamp, electric conductive means including a metal carrier for the battery extending from the opposite poles of the battery, compressible means fitted at one end of the carrier and having a contact but-ton for one poleof the battery, the opposite end of the carrier being of fitted with the electric reflecting lamp, and

contact on the lamp adapted to malte contact with theopposite pole of the battery, and means associated with said handle whereby the circuit of said battery'is closable through operating saidV contact button to electrically connect the poles of said bat tery through said conductive means.

2. A truncheon torch comprising a hollow body having one end weighted, a detachable handle for the opposite end of said body, a removable electric battery and reflecting lamp within said body, a light projector lens associated with said body and lamp, electric conducting means associated with said battery and poles thereof, one end of the handle being provided with a hole, av metal push rod fitted in the hole, a. push button on the outer end of the rod and disposed to be operable externally of the handle, and aV contact button associated with the electric means of the battery and contacted by the inner end of the rod.
