Description
Sept. 29, 1910 A. NATHANSON TOUCH OPERATED ELECTRIC LIGHT Filed May 6, 1968 United States Patent US. Cl. 24010.6 7 Claims ABSTRACT OF THE DISCLOSURE An electric light unit embodying a housing having a closed bottom and an open top supporting a detachable friction held cover plate. An annular collar on the cover plate contains an insulator tilt plate having diametrically opposed metal handle bars projecting through openings in the collar. The tilt plate carries an electric light bulb. A central opening in the cover plate carries a contact point and an inclined contact strip both connected by conductors to a source of electric supply within the housing. The lower terminal contact of the bulb is always seated on the contact point and tilting of the tilt plate in one direction will cause the contact side of the base of the bulb to engage the contact strip to close the circuit and light the bulb. A pair of magnets exteriorly of the collar seated on the cover plate are provided such that when the tilt plate is tilted by finger pressure on one handle bar the same will engage its associated magnet to cause closure of the circuit. Tilting of the tilt plate in the opposite direction by finger pressure on the other handle bar will cause the latter to engage its associated magnet to hold the tilt plate in inoperative position. Carried by the closure plate is a removable transparent dome.
The primary object of this invention is to provide an electric unit containing a source of electric supply and mounting a tilt plate carrying an electric light bulb having a pair of finger engaging handles such that a light finger touch on one handle will cause the tilt plate to close an electric circuit to the bulb to light the same and finger pressure on the other handle will open the circuit to put out the light.
Another object of this invention is to provide in the unit a housing having a closed bottom and an open top closed by a detachable cover plate friction hold to the housing and including an annular collar on the upper surface of the cover plate.
A further object of this invention is to provide an opening in the center of the closure plate with means supporting a pair of contacts connected to a battery or transformer connected to house current within the housing, and mounting within the annular collar the bulb carrying tilt plate with its finger handles projecting outwardly of the collar, the base of the bulb extending through the tilt plate having its lower terminal contact engaging one of the pair of contacts and when tilted the side of the bulb base engaging the other contact to close the circuit. A still further object of this invention is to provide a pair of magnets on the cover plate each to be engaged by one of the handles to hold one handle when the tilt plate is tilted to its operative position to close the circuit and when the tilt plate is tilted to is inoperative position to open the circuit the other handle will be held by its associated magnet.
A still further object of this invention is to provide the cover plate with a removable transparent dome.
Further objects of the invention will appear as the description proceeds.
To the accomplishment of the above and related objects, my invention may be embodied in the form illustrated in the accompanying drawings, attention being ice called to the fact, however, that the drawings are illustrative only, and that change may be made in the specific construction illustrated and described within the scope of the appended claims.
FIG. 1 is a perspective view of the finger touch operated electric light unit.
FIG. 2 is an elevational view in cross section of the 'electric light unit showing the transparent dome hinged.
FIG. 3 is a detail cross sectional view taken on line 3-3, FIG. 2.
FIG. 4 is an exploded view of associated parts of the electric light unit.
Referring to the drawings in detail a light or lamp unit 10 suitable for mounting in any desired location is seen to consist of a rectangular box like housing 12 having a base 14 secured thereto in any suitable manner and of larger dimensions such as to provide a lateral flange 16 extending outwardly from each of the sides of the housing. While the housing 12 is shown to be square in cross-section the same may be made cylindrical in form if so desired. It is to be noted that the bottom of the housing is closed by a bottom wall 18 to which the base 14 is secured.
Mounted interiorly on bottom wall 18 are a pair of spaced resilient leaf battery contacts 19, 20. A battery element 22 in inverted position is contained within the housing 12 with its contact poles 23, 24 respectively engaging the leaf contacts 19, 20.
A readily removable cover plate 26 dimensioned to seat directly on the top edges 27 of the housing 12 has its side edges lying flush with the sides of the housing 12 as seen in FIGS. 1 and 2. A depending spring finger 28 is secured to the underside of cover plate 26 in its closed seating engagement on the open end of housing 12. Securely and axially attached to the upper surface of the cover plate 26 is a cylindrical collar 30. Provided in the wall of the cylindrical collar 30 are a pair of diametrically opposed rectangular openings 32, 33, and centrally in the cover plate 26 there is provided an opening 35.
Within collar 30 and seated on top of cover plate 26 is a disc 37 preferably of insulating material having a central opening 38 disposed co-axial with opening 35. The insulator disc 37 may be secured to the cover plate 26 in any desired manner (not shown). Suitably mounted axially in disc opening 38 is a contact point 40 and to one side of the disc opening 38 there is suitably fixed an inclined or tilted contact strip 41. Fitted within the collar 30 is a light bulb carrying tilt plate 44 of insulating material provided with a pair of diametrically opposed metal handles 45, 46 arranged to project outwardly respectively through openings 32, 33 in the collar. An opening 47 is formed centrally in bulb carrying plate 44 and is provided with diametrically opposed notches 48, 49. A conventional light bulb 50 (of the automobile head light type) is provided with a base 52 and diametrically opposed projecting lugs 54, 55 which latter when inserted through opening 47 and notches 48, 49 will on a degrees turn of the bulb secure the bulb to the carrying plate 44. The lower terminal contact 57 of bulb base 52 will seat on the axial contact point 40 holding tilt plate 44 horizontal, as seen in FIG. 3. A pair of conductors 60, 61 electrically connect contacts 19, 20 respectively to contact strip 41 and contact point 40, as seen in FIGS. 2 and 3.
Seated on cover plate 26 and exteriorly of each opening 32, 33 of collar 30 are magnets 63, 64 which may be secured to the cover plate in any desired manner.
It is seen that by finger touching arm 45 of tilt plate 44 and pressing down a distance such that metal arm 45 will contact magnet 63, that the magnet will hold the tilt plate 44 in its tilted position as shown by dotted lines in FIG. 3. Thus tilted, the side of bulb base 52 will engage contact strip '41, closing the circuit and lighting bulb '50. The bulb 50 will stay lit as long as magnet 63 holds arm 45 of tilt plate 44. To open the circuit and to cause bulb 50 to become unlit, the other handle bar 46 is finger touched and pressed down to engage the other magnet 64 which will thereby securely hold the tilt plate 44 in its inoperative position (keeping bulb base 52 spaced from contact strip 41). At all times the lower terminal contact 57 of the bulb 50 will be in contact engagement with contact point 40.
Provided as a closure for bulb 50 is a protective transparent dome 70 having a peripheral ring 72 which may be either detachably secured to cover plate 26 by screw fasteners 74 (FIG. 1) or may even be hinged at one side as at 76 to the cover plate 26. A recess 78 is provided at each side of the dome to accommodate the handles 45, 46 and magnets 63, 64.
The electric battery operated unit is easily operated, efficient, fool-proof, simple to manufacture and of low cost. Instead of being battery operated, there may be provided within housing 12 a suitable transformer and the unit connected to the house current in the manner well known.
While certain novel features of my invention have been shown and described and are pointed out in the annexed claims, it will be understood that various omissions, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing from the spirit of the invention.
