Frank Berman, Pewaukee', Wis. Application October 17, 1950,:SerialNo. 190,594
This invention relates to new and useful improvements in portable lighting unit andv has for its particular aim the provision of such a unit for the automobile steering Wheel storage unit disclosed in my co-pending application Serial No. 180,497, filed August 19, 1950.
The storage unit consists, in general, of a disc mounted on a steering wheel and having depending therefrom a plurality of pockets to receive writing implements, cigarettes, a flashlight, a writing pad and the like. The lighting unit or flashlight of the present invention is ideally adapted to be'stored in one of the pockets of said storage unit.
One object of the invention is to construct the flashlightso that the illuminating means thereof is normally completely encased in an outer housing, but is partially removable from the housing and settable to direct a beam of light in any desired angular direction.
Another object of the invention is the provision of means for maintaining the setting of the illuminating means.
Still another object of the invention. is the provision of automatic switching means operated by the act of setting the position of. the illuminatmg means.
For further comprehension of. the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are moreparticularly set forth.

Fig. 11 is an enlarged fragmentary sectional view on line lI-H of Fig. 9.
The portable lighting unit, according to the first form of the present invention shown in Figs. 1 to 6, includes a rectangular housing 15 having an open top as shown. Said housing preferably is formed of a plastic material. Mounted inthe housing l5 for sliding movements up and down. relative to the open top thereof is a carriage .16 which may be either H-shaped or U-shaped, but which, as here shown, is of the H-shape, having side arms I! and a cross bar i3.
In order to facilitate raising and lowering the carriage 16 the upper ends of the side arms I! thereof are provided with loss. 20 which extend outward through suitable slots 2-! in the upper edge of housing I5. As shown, the said lugs project beyond the'housing wall and afford finger grips.
It is desired that the carriage be held automatically in whatever position itis located relative to-housing 15. To this end the outer edge of each carriage side arm I1 has serrations 22 and each side wall of housing I5 is provided with a detent extrusion 23 which engages said serrations. It will be seen, therefore, that the engagement of said detents in said serrations will retain the carriage in whatever position it is raised orlowered to.
Near its upper end each carriage side arm I! is provided onv its inner facewith a circular bearing extrusion 24 on which is mounted" one end of a circular hollow rotor 25 of plastic material. Referring particularly to Figs. 3,, 4 and 6, the rotor 25 has mounted in either end thereof a ring 26 or 21 of electrically conductive material, said rings bearing on the bearing extrusions 24. As shown the ring 26 has a breach 28 therein but the ring 21- is continuous. Extending from the rings 26 and 21 are strips 30 and 3|, respectively, said strips at their inner ends engaging the contact ears 32 of an ordinary bulb socket 33 secured within the rotor in any suitable way, such as by a screw. 34. Mounted in socket 33 is an electric lamp 35 which projectstowardan opening 36 in the cylindrical wall of the rotor, said opening being disposed in alignment with the breach 28. in ring 26, angularly speaking. Contact is made with the rings 26 and 21 by conductor strips 31 and 38 which extend along the inner faces of the carriage side arms I! in grooves therein, and have their upper ends bent off in grooves formed in the undersides'of the bearing extrusions 24-.
The conductor strips 31 and 38 extend through suitable holes at the ends of the carriage cross out 42 in the insulative cover thereof. The con-' ductor strip 38 extends downward and contacts the positive terminal of the lowermost dry cell 40. Secured to the strip 33 in position to insulate the same from the end of the uppermost dry cell 40 is a pad 43 of insulative material. The electrical circuit is completed by a conductor strip 44 which extends along the opposite arm l7 and connects the positive terminal of the upper dry cell with the negative terminal of the lower dry cell.
The construction is such that when carriage I6 is in its lowermost'position, the rotor is so positioned that the breach 28 of ring 26 is positioned over the bent over end of conductor strip 3.! and the circuit to lamp 35 is open. However, the carriage may be raised to any desired position and the rotor 25 rotated to any desired angular position. The rotation of the rotor 25 brings the ring 26 into contact with the bent over end of strip 31 completing the circuit and illuminating lamp 35; It will readily be seenthat with this arrangement the lamp 35 can be positioned to direct a beam of light in any desired angular direction.
It was mentioned above that the carriage l6 may be of U-shape. In this form the area below the cross bar l8 would be enclosed and would constitute a housing for the dry cells.
It is to ,be mentioned that, if desired, the side arms of the carriage may be telescopic so that the rotor may be extended even further above the housing [5. Further, if desired, the rings 26 and 2'! may be provided on the outside of rotor 25.
For innumerable purposes, a mirror 39 maybe cemented or otherwise secured on the frontfac'e of the housing l5. I
A modified form of the invention is illustrated in Figs. '7 and 8 wherein like parts are given the same reference numerals as above with a prime added. The purpose of this form of the invention .is to provide means for retaining the rotor 25 in the angular position to which it is set. To
this end the cylindrical wall of rotor 25 is serrated as indicated at 46 and a detent 41 extends from each side arm I? to engage said serrations, said detents straddling the grooves for the conductor strips 31' and 3S. Aligned with thecenter of the breach 28' in ring 26' is a deep roove 48 in the cylindrical wall of rotor 25', said groove serving to hold the rotor in its normalposition with lamp 35' extinguished even more securely than the serrations 46 hold the rotor in its operated or set positions. The remainder of the device is the same as described abovef Another modified form of the inventionis illustrated in Figs. 9, and 11, wherein like parts are given the same reference numerals as heretofore with a double prime added. The purpose of this modification is to provide the device with a combined stand and clip whereby it can be stood on a level surface or can .be clipped to a convenient object such as the sun visor of an automobile. To this end a stiff wire yoke 'BOhasitsVends level surface.
A short distance below the wells 5| a stud 52 projects from each side wall of the housing I5" and is. engaged by a side arm of the yoke 50 when the latter is in normal position with the upper portions of its side arms parallel with the side edges of the housing. As shown, the lower portions of the yoke side arms and, therefore, the latters cross bar, are ofiset angularly away from the stud 52 as at 53. Thus, if the yoke side arms are sprung about the studs 52 as a fulcrum the offset portions 53 become parallel with the side edges of'the housing l5" and form with the latter a strong clip to secure the same to any member 55 such as an automobile sun visor or the like.
In this last form of the invention the construction of the unit is the same as described above except for the changes described.
While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.
Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:
l. A lighting unit comprising, an H-shaped carriage having spaced side arms and a cross bar extended between said side arms, a bearing extrusion on the inner face of each side arm of the carriage near the upper ends thereof, a hollow rotor mounted on said bearing extrusions, a conductor ring in either end of the rotor engaged about said bearing extrusions, a breach in one of said rings, a lamp socket mounted in said rotor, electrical connections between said rings and said socket, a lamp in said socket directed in the same angular'direction as said breach, an opening in the wall of the rotor adjacent said lamp, dry cells mounted between the side arms of the carriage below the cross bar thereof, and electrical connections between said dry cells and said rings.
