This invention relates to new and useful improvements in portable electriclights and particular relation "to a portable electric light-in the form of a candle. 7 An object of theiinvention is to provide an improved switching means in'za light of the kind :stated wheneby a 'circuit'will be closed through a battery :andvbulbon the light being raised ofl a support, or'whereby the circuit to the bulb may be manually closed to remain closed while thelight is on a support as well as when the light is raised off the sup- A further object is to provide a light as stated and 1 including two switch elements either of which may be moved into engagement with 'a-contact to close a circuit to a bulb, and one of which is adapted to be normally positioned to move into engagement with the contact on the light being raised off a supporting surface and the other of which may be manually .moved into engagement with the contactirrespective of the position of the first.

Other objects-and advantages will become apparent from a consideration of the following detailed description taken in connection with the accompanying drawing, wherein satisfactory embodiments of the invention are shown. However, it is to understood that the invention is not limited to the details disclosed but includes all such variationsand modifications as fall within the spirit of the invention and the scope of the appended claims to which claims reference maybe had fora definition of the invention.

Referring in detail to the drawing, the improved candle light includes a base 10, preferably hollow and formed of sheet metal as shown. This base includes a centrally depending threaded portion 11 having an annular flange 12 to which a disc 13 of insulating material is secured as by means of rivets 14 and 15. Threaded into the portion 11 of the base is a sheet metal casing 16 which at its upper end carries clips 17 adapted to secure a globe or glass 18 to the casing.

A bulb 19 is threaded into a socket 20 electrically connected with the casing 16 and the center contact of the bulb engages the central contact 21 of a battery22 enclosed in the usual insulating covering 22a and located I within the casing 16. The battery 22 is held in position with its contact 21 in engagement with the central contact of the bulb as by means of-a flat spring. 23 of conducting material secured to the upper .end of a post 24 of insulating material as by means of :a relatively long rivet :25 which rivet "extends through the post and has its head26 disposed at the under side of the disc 13, whereby to form a contact and also secure the post to the disc.

Since the head 26 of the rivet 25 is arranged centrally or substantially centrally of the disc 13, it will be'apparent that there is no circuit between the bulb and battery until the space between the contact or rivet head 26 and the casingor base is bridged. Accord ing to the present invention, two switch elements are provided for bridging this space and one of these elements is adapted tobe entirely manually operated while the other is adapted to be normally automatic in its operation and to close a circuit between the battery and bulb on the light being elevated off a supporting surface.

bring its contacting portion 29 into engagement with the contact 26. A circuit will then] be closed frcm the battery. to the bulb, and through the casing 16 to the base 10, and through the rivet l tto the element 27,- and from that elemeiitthrough the rivet and spring 23-ba ck to the battery. The upturned edge 30 facilitates the sliding of the contact or switch onto. the contact-26. The automaticswitch element includes a a baseor mounting portion-31 pivoted to the discv 13 on the'rivet 15, and ,liaving a pair of upstanding cars 32 and a pair of stop lugs 31a and 315 on 'its'op'posite side. The circuitclosing member of t-heauto'matic switch includes a relatively elongated member 33 havinga contacting portion .34 and having one end portion ofl set and bent upon itself to provide a spring arm 35. 'Further, this. Y member 33 includes spaced ears 36 adapted to be received-'between'the ears-32 ofthe mounting member 31 and when-a .pin 37 is passed through the respective pairsofears, it will beappreciated that the member 33 is pivoted "to the mounting member, I 31 for movement in a vertical plane relative thereto and ab'outa horizontally extending pivot VVhen the automatic switching element is in place its normal position is such that its portion 34' is either in. engagement with the contact 26 or in line with said contact; When arm 35 is received between the body of the the parts 31-and 33 areassembled, the spring member33 and the mounting member 31 andicompressed so'that. it is constantly endeavoring to rock the member 33 about the pivot pin 37 in adirectionto force the end portion 34: toward the central contact 26.

, However,when the light is resting on a sup- I bulb as shown in Fig. 3.

port, the oii' set 38 of the member 33, will engage the, support and rock the member in a direction to take its portion 34: away from I the contact26 as'shownin Fig, 1 and open the circuitthroughthe lamp. As soon as the light is elevated or liftedfrom'the supv port, the spring arm ,35will ac-tto'rock the switch element 33 on its pivot 37 andhave its portion 34" engage the central contact 26 and complete a circuit through thebatteryand Since the mounting member or means 31 is pivoted on'the rivet 15, the'entire automatic switch element or means may be swung from its position where its contacting portion 34 is in alinement with the contact 26 as shown in Figs. 2 and 3 toan inoperative position as shown in Fig. 7. It will therefore be notedthat the automatic switch element has botha'vertical and a horizontal switch element. Its turning movement about its pivotal mounting 15 is limited in opposite directions by the stop lugs 31a and31b engaging the edge ofthe insulating disc 13. I Further, attention is directed'to the fact that the contacting portion 3 1 of the automatic switch element includes upwardly off-set portions 34a whereby the switch may readily slide onto the contact26 andalso the manually'operable switch element 27 may be moved on its pivot 14 to have'its upturned edge 30 p engage the contacting porti0n134 of the switch element 33' and rock the switch ele ment on its pivot 37 and against-the 'actionof thespring arni35 so'asto permit the contacting portion 29 of the manualswitch ele mentto enter under the contacting-portion 34 of the automatic. switch element to close the circuit. a I .1 f r. From the foregoingdescriptiQn', it Will-be clear that the 7 manual switch element. may be operated to close a circuit between the battery and bulb irrespective of the location of the light, and irrespective of whether or not theautomatic switch. element is in .ClI'Qlllt closing position; Further, it willbe apparent that the automatic switch element may be put out of commission by turning it onits vertical pivot which is the rivet 15 and that the circuit maybe operated entirely by the manual switching element.-

, Referring to the-modified form at the in vention, the parts are all the samewith the exception that the automatic switching element identified in Fig.8 by the numeral 39, does not include-a (spring arm similar to the arm 35 of the switching element 33 of the.

first form of the invention. In lieu of the arm 35 a spring 40 is provided and this spr ng includes an; arm alengaging the mounting member 31 and an arm 42 engaging the member 39 at one "side of the pivot pin 37 .Fur ther, the spring 40 includes an eye 43, to re-.

ceive the pivot pin 37 whereby the spring is secured in placef Obviously; the operation of themodifiedform of automaticflswitching' element is the same as that previously described and further description is therefore 2 7 believed unnecessary; Having thus set forth the nature of my invention, what I claim is: i
