lVith thepresent form of acetylene lamps used by miners, should the gas become" eX- means to provide light for the miner, thus requiring the miner to leave his worlr and have the lamp repaired or replaced. j
It is therefore an object of the 'invention to provide means for illuminating purposes that can be readily put into operation should the gas lamp be rendered useless.
Another object of the invention is to provide a duplex lighting system whereby the mechanism of one of the illuminating means provides a support for: the otherV illuminating means. y
Another obj ect of the invention is to provide a lighting systemof this character wherein the casingfor one of the energizing means serves to hold the other illuminating means on a support or head-gear. j
Another object of theinvention is to pro- A vide a lamp forming one source oi' illumr nation and a second lighting system forming a second source of illumination, the casing of the lamp and reflector therefore forming part oi the circuit of the second mentioned illuminating means. i l
A still further object orp the invention is to provide a lighting system using electrical energy and capable of being incorporated in various forms of lamps to be 'used instead of or when the lamps are not in use.
With these and other objects in view, the Y invention consists inthe improved construction and arrangement of parts to be herein- ,after more particularly described, fully j .i claimed and illustrated in the accompanying drawings, in which: Y e p `Figure 1 is a side elevation of an acetylene gas lamp with the inventionapplied,
Fig. 2 is a horizontal sectional view,
` Fig. 3 is a fragmentary perspectiveview*V Vrear portion or" ber 6.
of a head-gear showing the construction of the support, and
Fig. t is a sectional view of the battery casing showing the contact means.
Referring to the drawings, A designates a lamp preferably of the acetylene type,and B the reflector therefor. The lamp e. includes a bracket C which entends rearwardly loit the lamp and is intended to be supported on a head-gear D including a support E. rlhe'suppcrrt is provided with a laterally er;- tendmg slot 5 which penetrates one edge ot the support, the mouth of the slot being restricted.
ln order to provide illuminating means when the lamp is not in order or the gas thereof has become exhausted, l provide an illuminating means 5, comprising the lamp receiving portion 6 which is embedded in an opening' 7 formed in the reilector E adjacent the illuminating means or' the lamp.
.The member 6 `is not insulated from the reflector, as the reflector is intended to serve as electrical conducting means for the member 6.
The other portion or' the socket member comprises a conduit 8 which is biiurcated at one -end and pivotally connected to an arm 9 carried by the exterior portion of the lamp A. rl`he end portion 10 of the conduit S is externally threaded and adapted to receive an insulating sleeve 11, the end portion 12 of the insulating sleeve including a collar adapted to engage the the lamp' receiving mem- Projecting from the lamp casing is an v arm 13 towhich a cylindrical body v`14 is secured.
rin opening 15 is formed in the cylindrical body 1e and is adapted to permit unobstructedmovement oit theinger piece 16 carried by a contact member 17 disposed within'the cylindrical body 1e. The cylindrical body 14.- and the contact member 17 `cooperate to provide a switch by `means of which the current is controlled.
j A casing rearwardly or the lamp A. Thiscasing is composed oi two pivotal connected sections provided with a fastener F so that the cas ing may be readily opened when desired. rlhe end 19 oi' the casing is composed of insulating material and "is intended to receive aV pair of Contact members 20. Energizing means such as a battery 21 is intended to be disposed withinthe casing 18 with the ter-`4 18, is secured to the bracket C' minals thereof in engagement with the contacts 20.y Leading from the contacts eXte- Vriorly of the casing 18 is a pair of current conducting wires 22 and 23. The end portion of the wire 22 is extended to the conduit member 8 and is passed tlirouglithebifur-x cated portion adjacent the pivotal connection of said conduit to the arm 9 and into said conduit.` Insulating means 211 are disposed around the ends of the wire 22 so as to prevent closing of the circuit through the conduit member 8. rlhe end portion of said wire is provided with a spring 25 to the end of which a contact plate 26, is secured. The uninsulated end of the wire 22 and the spring 25 together with the plate 26 are disposed within the insulating sleeve 11, with the plate 26 closely adjacent the lamp receiving member 6. rThe wire 23 is extended through one end of the cylindrical body 1li and insulated from said body. The contact member 17 of the switch is intended to engage the end of the wire 23 to close the circuit'wlien desired.
A lamp 27 is screwed into the lamp receiving memberv 6, with the end thereof in contact with the plate 26. When it is desired to energize the lamp 27, the switch contact 17 is moved toward the end of the wire 23. This causes the closing of the circuit through the cylindrical body 14, arm 13, lamp casing A, reflector B and lamp receiving member 6. The other portion of the circuit being formed by the wire 22, spring 25,'and plate 26 in contact with the end of the lamp 27. It will 'thus` be seen that the lamp casing Aand reflector 'B are utilized in the circuit of the lamp 27 thereby eliminating unnecessary wire andrendering the device simple.
In applying the lamp to a support, such as thehead-gear D, the bracket C is passed through-the slot' Eand is prevented from disengagement therefrom by the restricted opening of the slot. The casing 18 is -thereby positioned between the support E andthe head-gearD to prevent disengagement of the lamp from the support so that it thereby serves two purposes.
To properly position the socket member 6' with respect to the relectorB, a supporting member 28' is carried by the socket member 6 rearwardly of the reflector B, said member including an extension 29'adapted to engage the insulating vsleeve 11. yThis member may be made of metaland serve as `*an additional means for conductingk electrical energy to the socket member'6.
An important-feature of the invention is that the casing of thelamp-not only serves as a support for the second illuminating means, but also serves as means by which current is transmitted to the lamp of the second illuminating means. The second illuminating means also cooperates with the lamp by. perv mitting the casing containing the energizing means therefor to serve as a fastening or holding device to prevent disengagement of the lamp from the support on the head-gear. In .addition to this the reiiector of the lamp Vis utilized to provide a support for the socket orV lamp receiving member of the second illuminating means. Notwithstanding these important features, the invention is simple in construction and can be incorporated in various forms of lamps to be used either as a separate lighting arrangement or when the lamp is out of order.
