G. H. -BARBER FLASHLIGHT Filed March 16. 1928 Patented Aug. 9, 1932 what GEORGE H. BARBER, or NRW ROCHELLE, NRWYORR, AssreNo'R ToRONnRL-ROTRIQQ CORPORATION, or NRW YORK, N. Y., A CORPORATION orv DELAWARE Application mear/Laren 1e, 192s. vserial' No.' 262,093.

rIhis invention relates broadly to the mounting of; an incandescent lamp at the end .Offa ashlightcasing'and thelike. More particularly, the invention relates to a flashlight 3 in'which the reflector-and lens are removable, so that theashlight may be stood onV end `with the `incandescent lamp exposed, to serve fasa stationary source of light and be, in effect, 1.a candle.

V9510 It'has been proposed to carry the incanldescent'lamp in a socket mounted upon a re- :movable end for the 'flashlight casing, to --which casing the socket is electrically and mechanically connected. 2 l5 nposed contact `for engagement with the positive terminal of the battery, which contact :has'rbeen resilient so as to be capable of yield- 20 ing to serve as a shock absorber orthrust nmember to minimize the thrust of the relatively heavy battery should the flashlight -f'all with its top end lowermost.

The lremovable end or plate supporting the lcasing by a'connection which has involved a tubular-metallic tting or bushing secured to 'the end of the casing and serving as a portion of-'one conducting path for the electric cur-` rent supplying the lamp. This bushing has had .an-inturned flange formed with'a socalled bayonet vslot by which the lamp supf the lampssocket supporting plate may bel 4; turned to bringthe lugs beneath the flanges and thus securely, although removably, an,

-chor the lamp support to theend of the bat- .tery casing.

The cup shapedmetallio bushing in which f 4these-called bayonet slot is formed, has hady Gne electrical connection for the incandescent filament has consisted of a centrally disl e5 :lamp socket has been secured to the flashlight 'ing elementy to retainthe cross bar-.in \po`si" g an outwardly extending flange on 'its lower edge adapted to'rest on the upper end ofthe tube forming the battery casing. The bushing has been secured t'o the tube by lmeansof a metallic' hood collar`formed with threads-T55 to receive the rellector and other parts. This hood collar has been secured to the'tube by Y suitable rivets, eyelets or the like,.and has retained tlie'bushing in place on the ashlight. tube by engaging, by means of a 'l'ange'go on its upper end, a fibre ring resting on the outwardly extendingI flange of the bushing and thereby insulating the'Y bushing from the hood collar. y

It will'be seentliat this manner of securingm or'mounting the bayonet slot bushing on the end of thelibre tube involves a number of operations, such as the formation of a flange on the bottom of the bayonet slot bushing, the provision of a fibre insulating ring, the proim vision ofa hood collar, and the riveting of this hood collarto the libre tube. Y

The Vpresent invention seeks' to simplify the Amanufacture ofV liashli'ghtsby they omis sion of parts,but with Vthe retention of allf the advantages and functions of thebest `types of structures as at present known. To this endithe'lampsocket and contacts are mounted upon whatis, in eEect, a cross barKA which is removably mounted in slotsk or redac -ces'ses formed in the walls of the'batteryvcasing, the metallic threaded hood collarserving, if desired, to'close one Yof the slots and preventthe passageotf the bar too farV in that n direction and the hood collarrbeing'formed '-85 with'an Openingi'n register with the other slot to permit relative movement of thecross bar during its insertion or removal. One of the electric contactsserves, in known manner," as a thrust member, while the other `contact e0 carried with the cross bar not only elects contact with the conductor leading, say, from the switch', but also'serves as a yielding positiontion in the slots or recesses. I Y95 "The inventionl also seeks vimproved contact strips foruse in connection lwith this or any type of support for the lamp and particularly such contact strips as may funcx tion asthrust members. '190 ends of the vcross-bar are unobstructed and" l the cross-bar is retained in operative posirmtion by means of one of the electrical conassembly in manufacturing and which shall ductors, leading, say,'from the'circuit controlling device on the casing;

The invention also has for its object the provision of an easily receivable or attachable lamp socket support whichshallnieet the requirements of quantity production and be practical and e'ective in use.

These andr other objects of the invention and the means for their attainment will be kmore apparent from the following detailed description, taken in connection with the accompanying drawing, illustrating embodiments thereof whereby the invention may be practiced and in which Figure 1 is a View in verticalsection showing the upper end of a .flashlight with the cross bar type of incandescent lamp support forming the subject matter of this invention.

Figure 11 .shows a cross-bar lamp socket support in a metallic casing, the cross-bar being supported byflanges delining the aper- 1 tures by which the cross bar is inserted in position. i v p Referring lirst to Figure v1, the metallic reflector 11,.supports the 'lens 13 and is in turn supported upon a cylindrical hood 10 to which the lens and reflector are secured by the lens ring 12 by the threaded connection 14. Tubular member or hood 1() is illustrated as removably secured, as by a threaded connection 15, to the threaded hood collar 16 which may be secured in any convenient fashion to the upper end of a tubular casing 17 which is preferably of insulating material and may be formed of a non-metallic substance, such as fibre.

t diametrically opposite sides of the casing 17 .adjacent the top end thereof, there are formed pockets or elongated apertures 20, 21 adapted to receive, respectively, the extended end portions 22, 23 of the so-call-ed cross-bar lainp'socket support. It will be observed in Figures 3 and 4 thatthis cross-bar member is disc-like in form at'24 to substantially close the end or opening of the flashlight casing` 17, thus forming an end for the casing opening, and is formed upon diametrically opposite sides with the extended ory ends 25, 26 will conform substantially to the outer marginal surface of the casing 17. One of these extensions or lugs 22 is shorter than the other lug 23 and is adapted tobe received in the pocket or aperture 20iandto abut when the disc 24 is in operative position against the threaded wall of the hood collar 16 and b e positioned thereby.l The other lug 23 which is in the end of the casing 17, the curvilinear'go theY longer one, is adapted to be positioned in the opposite pocket or aperture 21 and also passes through an aperture 27 formedV in the thread-ed hood collar 12 in register with the pocket or aperture 21 in the flashlight casing 17 so that, to permit insertionor removal of the lamp support 24, it may be moved to the right as viewed in Figures 1 and 2 until the shorter lug 22 is clear of the aperture or recess 20 whereupon the longer lug 23 extends outwardly of the aperture 27 and the cross-bar 22-24 may be rocked in the apertures 21, 27 to permit the elevation of the opposite end of the cross bar carrying the shorter lug 22 and permit its removal in a manner readily understood upon inspection of Figure 2, the apertures 21 vand 27 being of a greater dimension, longitudinally of the casing-17, to permit the biasing of the cross-bar. The threaded lower end of the hood 10 retains the crossbar in operative position.

The scope of the invention which is contemplated will now be described. The

socket support in the construction described as above is inserted by tilting the support s0 Tec lthat aportion of the support .ora lug thereof- Vlo toinsert thesupportgtherein inthe tilting manner described. A lamp socket support constructed to be so. insertedlis readily securedin'place either permanently orfor subfsequent ;removal by removing the .means kwhich retains the support in position' in the pockets. VWhere the support is permanently 'secured in position, 'theconstruction takes advantage of thenovel and effective manner of inserting the support, whereas where'the supportv is ,also removable, the constructionnot 'only utilizes the advantages obtainable from the manner of insertion,but also takes :advantage of the nfact that the support is removable for inspection and repair or to enable batteries stuck within the casing to be pushed out through the top end thereof.

The crosssbar member 24is`formed with a centrally disposedaperturev through which the threadedv end 31 of the incandescent lamp v32 mayextend forelectrical connection with the iiashlight battery and upon its upper face the lamp support 24 carries a perforated plate or escutcheon 33 uponwhich the threaded lamp socket 34 is mounted which is secured to the cross bar member, 24 as by the eyelets 35,36. One of these eyelets, say the eyelet 35, also carries, upon tlie'lower face of the kcross-bar 24, a contactk member in the form of a fiat elongated plate or strip 39 ywhich is prevented fronr rotation aboutthe eyelet 35 sayby thel lug l40 struck inwardly into the material of which the cross-bar 24 is made and which is formed with a downwardly eX-V tendingspring Contact portion 41 which en-v gages, at all times when thek cross-bar is in position, the electricalconductor 42 leading from the circuit closing device 43 at the side of the flashlight casing 17. i

Also, upon the lower face of the cross bar member 24, andpreferably extending in a direction angularly disposed with respect to the'general direction of the escutcheon 33 on the top face, is the central Contact thrust member which is `formed generally of two parts and comprisesV aV strip or ribbon 44 of conducting material extending across tne hole30 in the cross bar member 24 and pressed Vinwardly within the hole as at 45 to serve as a. bearing contact' for the end31 of the lamp 32. Beneath thisstrip'44 there is a generally U-shaped member 48, also of metallic or conductingmaterial secured at` the arms 48, 49together with the ends of kthe strip 44 immediately thereabove to the v Macross-bar member .24 byl means ofV the eyelets Y51v and onearm 48 of this-U48f-5O is formed Vwith an inwardly vand downwardly extendvvingy resilient contact member 52serv1ng as. a

yielding orresilient shock absorbing contact zfor` engagement with the positive terminal of` xthebattery (not shown) as a thrust member.

'It willthus be seenthat the circuit'from the battery through the lamp'includes, let us say, the positive terminal ofthe battery (not `show.n).,'the resilient shock absorbing contact y 52 vthrough the ribbon 44vwhere it contacts witlrthelJ-shaped carrier contact arm 48 to .the endv terminal 46 of the incandescent lamp andfrom the filament and 'threaded terminal through the socket 34 and escutcheon 33 through the Veyelet 35 and strip 39 'to the yielding contact conductor 42, switch43 and then back to the negative Contact of the bat-k tery` (not shown), as'will be understood.

lThe manner of insertion'and removal of this cross-bar member should beV readily apparent from. the foregoing description. It will'be appreciated that it isv not permanently secured-in anyway to the casing 17 but is non mally prevented from removal by the engagement of the threaded end'l, of the hood lOvwith the one lug 23 vand the engagement of the threaded hood collar 16 with `the shorter lug 22 on the other side. 'The crossbar is inserted by 4first passing the longer vlug 23 while the cross-bariis tilted, as shown in -Figure2, through the opening 21 in the wall ofthe flashlight casing l? and the opening 27 in the hood collar 16, a suflicient distance to permit the shorter lug'22 to pass downwardly inside of the flashlight casing and enter the recess 20. At this time the resilient contact conductor 42 is depressed and/so soon as the shorter lug 22 is linregister with the recess20 and the cross-bar member 1s released and free to move, the tendency ofthe resilient Contact 42 to return to normal position, causes the cross vbar to shift laterally and the shorter lug .22 lto enterthe recess 2O and the cross-'bar is retained yieldingly in position with the vouter edge 26 of the lon-ger lug 23 substantially iiushwith the outer surface of Y the -threadedhood collar 16, so that theV hood 10.may be screwed thereon. andy retain the cross-barin position. y

It will benoted that'in orderto be retained in position within the pockets, the lamp socket support must haveanover-all dimension, including the portions of the support or the lugs which are inserted into the pockets, which is greater thanthe distance between the proximate edges of the pockets. TWith this over-all dimension, the lamp socket support will be supported in thepoclrets and must be inserted by tilting a portion or lug of the support into one pocket far. enough to clear the casing with the opposite portion or lug of the support so that that portion or lug of the support is insertablein the other pocket. Inl the preferred construction in which both pockets restrain the lamp socket support against transverse movement in all directions but not against axial movement, the opposite portion of the lamp socket support or lug must clear the casing until the support isv opposite the other pocket or in the plane of the pockets at which time the support is moved to slide the support or lug into the other pocket.

This construction is particularly rugged, is simple and easy to manufacture and since all contacting parts include preferably a fibre or non-metallic element, there is little chance of corrosion which would prevent the ready removal of the lamp socket, which removal is sometimes necessary to permit the forcing out of the flashlight battery, incase it is distorted, by permitting the battery to be pushed from the upper end. This con-v struction due to its simplicity is also a very much less expensive construction than that heretofore used. An added advantage of this type of cross bar construction is that the cross bar is yieldingly held in position and is capable of slight lateral movement thus absorbing to a great extent shocks and vibrations and preventing their transmission to the filament of the lamp.

A modification of the cross-bar is shown in Figures 6 and 7. This cross bar 60 is illustrated as rectangular in construction, although it will be obvious that it may take any other form between the-lug-like ends 61, 62. The ends 61, 62 of this cross bar 60 are adapted to be disposed within apertures 63, 64 diametrically opposite one another in the walls of the casing 65 and the cross-bar is permanently held in place by a threaded hood collar 66 which may be secured in position say by staking portions thereof into the casing 65. The escutcheon 83 carrying the lamp socket 34 is carried on the upper side of the cross bar 60'and is riveted thereto,` one of the rivets being adapted to carry a connection 67 with the circuit closing device at the side of the casing as in the previously described embodiment. Substantially transversely to the longitudinal medium line of this escutcheon 38 is a rectangular contact carrier member or frame 68 having an inwardly and downwardly directed thrust member contact strip 68 which is carried on the frame and secures and supportsv a contact 69 similar to that heretofore described. This device is permanently disposed within the end of the flashlight casing and is normally irremovable.

Still another modification of the cross bar is illustrated in Figures 8 and 9. This cross bar 70 is also illustrated as of generally rectangular shape and its ends 71, 72 are disposed Within recesses or apertures 73, 74, diametrically disposed with respect to one another, and formed in the end ofa fibre or non-metallic tube 75 whereof the upper end has threads 76 molded therein so thatno threaded hood lcollar is necessary. The ends 71, 7 2A .of the'y cross-bar are also formed with the threads 77, to cooperate with the threads formed on the fibre casing. This cross-bar 70 is yieldinglyk held in position by permanently securing the contact member 78 leading from the switch by means of a rivet, as before or it may be removably secured as by a bolt 79. Either securing means secures the base of the socket to lugs 80 formed on the cross bar. On the lower side of the cross bar there is a single strip of metal 81 which is not depressed into the hole 82 for theend of the lamp, but the hole is made large enough for the end of the incandescent lamp contact terminal to pass completely'thcrethrough and contact with this strip 81, the strip 81 being secured as bythe rivets 83, which also secure a downwardly extending shock absorbing contact or thrust member 84 making the contact with the positive terminal of the battery, (not shown).

A modified form of thrust member contact is illustrated in Figure 10. Across the bottom of the hole (not visible) in the crossbar 124 is secured a strip 144 which may be wider at one end and be fastened by two eyelets 145. At the other end it may be fastened by a single eyelet 146. The eyelets 145 also secure at one end, a downwardly bent contact strip 149 similarly shaped, except for its deflected portion, and having its free end disposed sho-rt of the eyelet 146.

Instead of a fibre tube the casing may take the form of a metallic. tube as shown in Figure 11 formed with threads 91-for the hood 10, if desired. Diametrically opposite one another, apertures 92 may be formed in the threaded end 91 to receive any of the cross-bars heretofore described, the edges of the apertures 92 being preferably defined by inwardly directed flanges 93 as additional supports. Obviously any of the modifications hereinbefore described are applicable to a metallic casing 90.

Various modifications will occur to those skilled in the art in the composition and configuration of the component elements going kto make up the invention as a whole. Certain of the elements described herein are capable of independent use on use in combination with one or more of the other elements described herein or are interchangeable and no limitation is intended bythe phraseology of the foregoing description or illustrations in the accompanying drawing except as set forth in the appended claims.
