may, or CHICAGO, ILLINOIS, Ass'reuonsro COMPANY, or CHICAGO, ILLI1NOIS,A'COB- SWITCH FOR EXTENSION LAMPS.
Application filed October 25, 1924- Serial No. 745,803 1 This invention relates to a new improved switch for extension lamps and more particularly is incorporated in the lamp structure and forms a part thereof.
This invention is particularly applicable to extension lamps of the type now in general use as troublelamps on automobiles. These lamps comprise reels for handling the extension wire, these reels being rotated by to provide a new and improved switchas sembly for lamps of this character and more particularly a switch which is operated by the ratchet control means of the lamp.
It is a further object to provide switches of this character i normally closed and is opened when the ratchet is put out of operation.
It is also an object to provide a switch of this character which is simple in design and construction and which may be readily incorporated in existing types of lamps without material alteration of their design and construction.
Other and further objects will appear as the description proceeds.
In the drawings we have shown a preferred form of construction by way of example. In the drawings- Figure 1 is a vertical section of the lamp construction taken adjacent the side of the lamp.
Figure 2 is a vertical section showing the portions removed in the section of Figure 1.
Figure 3 is a fragmentary section similar to Figure 2 but showing the ratchet in the ofi position.
Figure 4 is a fragmentary section taken on line H of Figure 2.
Figure 5 is a fragmentary section taken on line 5-5 of Figure 3.
to a switch of this character which n which the switch is t Figure 6 isa front vertical section taken back of'the cover with the lamp removed.
The form of lamp shown comprises'the casing 11, the front plate. 12' and thesides 13 and 14. The lamp supporting member 15 1s secured to the front plate 12 by lugs 16, and the cup 17 is threaded into the'member 15. The lamp 18 is removably fitted into the members 15 and 17. The 'lamp' is connected to the reel 19 by the double conducting cord 20. Qne end of one conductor of the double" cord is grounded to the reel 21. The end of'the other conductor is. se-
cured to the spring contact: 22 which latter is mounted upon the reel by a non-conducting support.
Referring now to Figures 1 and 2, the spring contact 22 is adapted to engage the contact ring 23, which latter is secured to the insulating support 2 1. This insulating it support 24 is secured to the side l t of lamp casing. The spring contact 25 is supported upon the insulating member'24 spring contact is through the lamp casing by screw- 26 and suitable means upon the outer side of the casing. These means'formno' part of the herein. The ring contact'23 is provided with the extension 27, which under-lies the end 28 of the spring contact 25; The end 28' 'is provided. with the off-set portion 29, the purpose of which will be described hereafter.
The reel 19 is provided uponone edge with'the series of serrations 30. The dog 31 is pivoted upon the pin 32 secured to the side 14 of the lamp housing. This dog 31 is the Y and is insulated from the lamp casing. This electrically connected present invention and need not be described provided with an inturned end 33 adapted to engage the serrations 30 of the reel. The spring 34, which is secured by rivets 35 to the casing member 11, engages the end 33 of the dog and normally urges it into engagement with the reel. The ratchet control. lever or plunger 36 passes through the guide 37 secured to the front of the lamp casing and carries the member 38, which tter is provided with the slot 39 enclosing the pin 32.
With the plunger 36 in its outer position as shown in Figure 2, the portion 40 of the member 38 engages the portion 41 of the dog 31. As clearly shown in Figure 3 when in Operation, the linger 43 is located as shown in Figure 4. In this case, the members 28 and 27 are 1n contact thus closing the lamp circuit. l pressed inwardly to the position shown in Figure 8, the ratchet is thrown out of operation and the reel spring will operate to wind up the extension cord 20. l/Vith the parts in this position member 43 has passed between the members 27 and 28 and since it is of nonconductive material, the lamp circuit 1s broken.
The oft-set portion 29 01 the member 28 serves to guide the finger 453 as it passes between the members 2? and 28. v
It will be apparent from the construction shown and described that when the ratchet isplacedin operation by pulling out the plunger 86, the lamp will be lighted. This movement of the plungerwould normally take place before drawing out the lamp regardless of whether the plunger controls the ci'rcuit, consequently the lighting of the lamp at the time when it is desired lighted is accomplished in the normal operation oi the lamp. WVhen it is desired to reel up the lamp and return it to its housing the plunger will be pushed to throw the ratchet out of operation. This movement. automatically puts out the light which is then no longer needed. if the lamp is desired for use While in its Vhen the plunger 36 is It will be obvious that comprising a spring pressed dog adapted to engage serrations formed on the reel, a lever adapted to move the dog out of engagementwith the serrations, and a switch for the light circuit operated by said i lever.
