Application led January 25, 1918. Serial No. 213,704.

To all whom t may concern.'

Be it known that I, MORRIS BALKE, a citizen of the United States, residing at Peters, in the county of Austin, State of Texas, have invented a new and useful Adjustable Electric-Light Holder; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved eX- tensible trouble light for automobiles having means for attaching the same to the vdash board, and one of the objects of the invention is to provide an improved device of this kind, which is simple, efficient and practical in construction, and may be manufactured for a small cost and sold at a reasonable profit.

A further object of the invention is to provide an improved device of this kind consisting of a reel or drum on which the cord of the bulb is adapted to be wound, formIng a link in the circuit between the bulb and the source of supply, for furnishing current to the bulb.

A further object of the invention is to provide improved tensioning means for the drum, whereby as the bulb is extended, the cord thereof will automatically rewind on the drum after finishing using the bulb or the light.

4 In practical fields the details of construction may necessitate alterations falling within the scope of what is claimed.

' The invention comprises further features and combination of parts as hereinafter set forth shown in the drawings -and claimed.

In the drawings Figure 1 is a view in elevation of the improved spring tensioned reel or drum for the cord of the bulb, and the supporting plate for the real or drum.

Fig. 2 is a front elevation of the same.

Fig. 3 is a sectional view on line 3-3 of Fig. 2.

Fig. 4 is a-sectional view on line4-4 of Fig. 1.

Referring more especially to the drawings, 1 designates a supporting plate, which may be constructed of any suitable material, preferably insulating material and is adapted for attachment to the dash of an automobile in any suitable manner. A spindle or shaft 2 has its threaded end 3 engaging through the plate 1. A collar-4 formed integral with the spindle or shaft engages the outer face of the plate. A nut 5 (which is countersunk in the inner face of the plate 1) is secured on the threaded end of the spindle or shaft to clamp the plate between the collar and the nut. The outer end of the spindle or shafthas a cylindrical enlargementI 6, and where it connects to the spindle, it is provided with an annular flange 7. An insulating sleeve 8 is fitted on the spindle or shaft and is formed with an integral collar 9. One end of this insulating sleeve extends between the flange 7 and the spindle. A metallic sleeve 10 is fitted upon the insulating sleeve, and the collar 9 engages between one -end of the sleeve 10 and said flange 7. The sleeve 10 near its inner end.

has an integra-l collar 11, and the enlargement 6 has an integral collar 12. The reel or drum consists of the inner and outer end sections 13 and 14 which telescope the oppo.

site end portions of an, insulating drum sleeve section 15. The drum sleeve section 15 has its outer cylindrical wall provided with an integral ri-b 16, which fits between the adjacent ends of the drum sections 13 and 14. By means of suitable screws 17 the drum sections 13 and v14 are secured to the insulating sleeve drum section 15. By means of the drum sleeve section 15 the drum sections 13 and 14 are insulated from each other. The drum section 13 has a circular flange 18 and the section 14 has a circular flange 19. The drum section 14 has an integral head 20 through which the enlargements 6 of the spindleor shaft 2 extends, there being suitable ball bearings 21, to assist in permitting drum or reel to easily and freely turn. A suitable colla-r or nut 22 is threaded on the enlargement 6 to hold the head of the drum section 14 adjacent the collar 12 to retain the ball bearings in place. A suitable pin 23 secures the collar or nut 22 against rotating on the cylindrical enlargement 6. A circular plate 24 (which has an opening 25) is secured by screws 26 to the flange 27 of the drum section 13, and constitutes the head for the other end of the drum or reel. This circular plate 24 near its opening 25 has a flange 28, between which and the integral collar 11, suitable ball bearings 29 are disposed, to further assist in permitting the drum or reel to easily and freely rotate. The circular plate 24 is further provided withv gear teeth 30 on its marginal edge, with which the teethof the gear 31 engage. A suitable spindle 32 extends through the supporting plate l, and is provided with an integralcollar 33 engaging the outer face of said plate. The supporting plate l is clamped between the nut 34 (which is threaded upon the spindle 32 and countersunk in the supporting plate l) and the integral collar 33. The gear 31 is mounted upon the spindle 32, there being ball bearings 35 between the hub ot the gear 31' and said collar 33. Additional ball bearings 36 are arranged in the hub of the gear 31 for engagement with the spindle 32. A suitable nut 37 is threaded to the spindle and telescopes into the hub of the gear 31 forretaining the ball bearings 36 in place. By means of the ball bearings 35 and 36 the gear 31 easily and freely rotates. A suitable spring 38 is coiled about the hub of the gear 31 and has one end secured at 39 to the hub, and its other end to a pin 40, which is carried by the supporting plate 1. The gear 3l has an annular flange 41 overlying and guarding the tension spring 38. Since the gear 31 is under tension of the spring, and is meshing with the teeth of one of the heads of the drum, said drum is so under tension, that when the cord 42 of the bulb or light 43 is unreeled from the drum, it will automatically rewind on the drum, when the light or ybulb is released. @ne of the Wires or leads 44 of the electric light or bulb is connected to a binding post- 45 of the drum section 14. rlhe other lea-d or wire 46 of the light cord passes through an opening 47 of the drum sections 14 and is connected to a binding post 48 of the drum section 13. A wire or lead 49 (which is connected to a battery 50) is connected in any suitable manner to the inner end of the spindle 2. wire or lead 51 (which is also connected to the battery 50) is connected at 52 to the spindle 32. The wires 49 and 51, and the battery 50 are disclosed to merely illustrate a conventional manner for furnishing current supply to the light or bul-b, and it is obvious that any other conventional method may be employed. lt is further apparent that the connections may be made other than shown. Normally the cord of the light or bulb is wound about the drum, and the bulb or light may be supported in some suitable Laatse? holder (not shown), to keep the drum from rotating. However, when it is desired to use the light or bulb, a pulling action is imparted on the cord, which will unreel from the drum, which, since it is under the tension of the spring tensioned gear 31, will rewind the cord when the light or bulb is released. The circuit involving the wires 49 and 5l may form a link in the lighting circuit customarily used on all automobiles,

and when this circuit is closed current passes from the battery 50 to the spindle 32 by way of the wire l5, and by way of the gear 31 to the drum section 13. passes over wire 46 to the bulb, and from the bulb. to the binding post 45 by means of the Wire or lead 44 and then through the drum sections 14. F rom the drum section 14 the current passes tothe cylindrical enlargement 6 along the spindle 2, back to the battery 50 by way of the wire or lead 49.

The invention having been set forth What is claimed as new and useful is winding reel or drum for a trouble light cord, comprising in combination with a supporting plate, a spindle iixed to and carried thereby, a sleeve insulated from the end and the body `of said spindle, a drum adapted to rotate on the outer end of said spindle and said sleeve, said drum comprising inner and outer end portions, the former being in circuit with the sleeve and the latter in circuit with the end portion of the spindle, means for insulating the former trom the latter, the former being in circuit with the source of electrical supply, which in turn is in circuit with the spindle, the latter being in circuit with anelectric light bulb, the cord of which is connected to the latter and adapted to Wind about the drum, the former being in circuit with the bulb, and a spring tensioned gear having gear connections with the former, whereby, as the cord is unreeled, the drum will automatically rewind the cord.

ln testimony whereof l have signed my name to this specification in the presence oit two subscribing witnesses.
