DETACHABLE BATTERY LAMP.
Application filed November 21, 1925. Serial No. 70,518.
This invention relates to improvements in detachable battery service lamps, com-' monl called trouble lights. An object of this invention is to provide a low voltage trouble-or working lamp that may be used in taking batteries from automobiles at night, or for other appropriate purposes,
Another-object is to provide a trouble lamp that may be used with practically any defective battery, It very seldom happens that a defective battery will not have at least, one cell that will give a three ampere light. I
A further object of this invention is to provide flexible connections to the trouble light thereby making it possible to bend the light to any direction desired, the connection being constructed to give the needed flexible qualities, at the same time assuring suflicient rigidity for properly supporting the light. Other objects will appear in the following detailed description, and in the single sheet of drawings, herewith made apart of this application:
In the drawings,
Fig. 1 illustrates a sideelevational view of the trouble lamp and connections in as sembled form.
Fig. 2 represents a sectional side elevation- 30 al view of the trouble lamp, showing the lamp and circuit connections thereto in proper assembled relationship to each other.
Fig.3 illustrates in perspective the different elements of the circuit connections, arranged in series previous to" placing them to ether in assembled form.
umeral 1 designates a detachable battery service light, or more commonly called trouble light, havin flexible circuit connections 2 and 3 leadmg therefrom, the free ends of the connections 2 and 3 being supplied with terminal clips l and 5. In order to provide sufiicient rigidity for supporting the light in a desired position, at least one of the flexible circuit connections as, for instance 3, is supplied with an outer covering comprising metal strips 6 wound spirally over the usual insulating material 7 of the ordinary flexible connection. The flex- 1ble circuit connections 2 and 3 are placed in circuit with the lamp preferably by means of the arrangement disclosed in Figures 2 9, 10 and 11 may be of any suitable material.
The terminal spring clips 4 and 5 are readily adapted for connection with the terminal elements of a storage battery. In this invention a low voltage troublelight is provided, preferably a 2 volt light, it being understood that almost any defective battery will have at least one cell that will give a three ampere light, wherein other devices now in common use call for a 6 volt light, which obviously, makes it impossible to supply a means of. light from the ordinary defective battery. This invention provides a light and connections which can be easily and quickly attached across a center cell of the battery. The flexible connections havingat least one connection of comparative rigidity making it possible to maintain the trouble light in a reasonable set position when desired. This invention is particularly adapted for tourists use, and may be utilized by all service cars.
What I claim is:
In a trouble lamp, flexible connections the free ends of the flexible connections for the purpose of connecting with the ordinary terminal elements of a storage battery.
