Application filed December 27, 1921; Serial Iifo. 525,207.
To all whom it may concern:
Be it known that 1, WILLIAM H. LEFFING- WELL, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Devices for Demonstratin Lighting Effects; and I do declare the fo lowinfg to be a full, clear, and exact description 0 the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in devices for showing the results which difierent colored wall decorations, such as paper or paint, have upon the problem of lighting any room and my invention aims to provide a miniature room provided with illuminating means and with a peep-hole through which it may be viewed, said room being provided with changeable colored panels or means, so that the lighting efi'ects produced with diflerent colored paper, paint, etc., may be readily determine A further object of the invention is to provide a deviceof the character set forth equipped with any suitable light meter, such as the well known foot candle meter, so that the actual candle power absorbed by different colored wall decorations, may be accurately. shown.
Yet another object is to provide a demonstrating device which will be simple and compact and may be readily carried from place to place.
With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the descriptive matter being supplemented by the accompanying drawings. 1
Figure 1 is a side elevation of a demonstrating device constructed in accordance with my invention.
Figure 2 is a top plan view.
Figure 3 is a central vertical longitudinal ectional view as indicated by line 3-3 of Figure 4 is a horizontal line 4-4 of Fig. '1.
Figure 5 is a vertical transverse sectional view on line 5-5 of Fig. 3.
' Figure 6 is a longitudinal section as indicated by line 6-6 of Fig. 4.
Figure 7 is a perspective view of one of the removable side panels.
In the form of the invention herein dissectional vie'w on 1 guides 9. It wil closed, the numeral 1 designates a housing which is preferably provided with a hollow base 2 having a drawer 3 in which a number of the side and ceiling panels, hereinafter described, may be carried. The top 4 of the housing 1 is .by preference hinged thereto as indicated at 5 and said top is here shown of hollow form to contain batteries and other electrical accessories which are preferably used. Preferably the housing 1 is divided by a vertical transverse partition 6 into two compartments which constitute miniature rooms and said housing is provided with a peep-hole 7 for each room, a suitable guard 8 being mounted around each peep-hole to exclude light therefrom by contact with the head of a person looking into the room. The corners of each room are provided with suitable vertical guides 9 with which side panels 10 are slidably engaged. These panels may be removed and others substituted therefor when the top 4 is in open position, at which time a ceiling panel 11 is 1 150 accessible, said ceiling panel being supported in any preferred manner, for instance by resting upon the upper ends of the l l of course be understood that the side panel 10 adjacent each peep hole 7 is necessarily provided with an opening 12 for registration with the peep-hole.
Several sets of the side panels 10 are employed and all panels of each set are of the same color, but each set of panels is a different color from the other set so that by removing one set of panels and inserting another, the miniature room will be decorated in a different manner. Similarly several of the ceiling panels 11 will be used and difierent colored ceiling panels may be demonstrated in connection with different colored wall panels so that numerous effects may be obtained. In order that the lighting effects of light and dark wall decorations may be efiectively displayed, I provide means such as an electric light 13, for illuminating each miniature room. This light is preferably carried by the bottom 14 of the hollow top 4 and current may well be supplied thereto by appropriate batteries 15 located in said hollow top, a rheostat l6carried by the upper side of the hollow top 4 and appropriate wiring betweensaid rheostat and the light or lights 13. When the construction shown is employed, each ceiling panel 11 is formed with an opening 17 through which the light 13 extends.
' exist in a full sized room.
In order that the exact foot candle power of light in the miniature room may be measured, thus making it possible to prove the relative effects of light and darkwall decorations, I prefer to mount a suitable foot candle meter 18 in each of the miniature rooms, so that it may be read while looking through the peep-hole 7. A battery 19, located 1n the hollow top 4, a volt meter 20 carried by the top 4,. and a rheostat 21 also carried by said top are suitably wired to the meter or meters as shown clearly in Fig. 3.
I make no claim to the construction of the foot candle meter and its association with the battery, volt meter and rheostat, as this is a well known article now manufactured by the General Electric Co. I have merely shown this conventional type of meter to disclose the fact that I contemplate the use of some efiicient light meter in connection with the features above described. By properly operating the rheostat 21 and the light controlling rheostat 16, different lighting effects may be obtained and accurately measured, and whenever desired, the panels in either room may be removed and replaced by others of a different color or colors. While I have shown a hollow base for the housing 1, in which to conveniently carry the panels, it will be understood that this feature is not essential, even though it is very desirable. Furthermore, while a hollow top such as 4 is preferred to carry all lighting and light measuring accessories, it will be understood that this top might be replaced by one of any other design, that lighting or llluminating of the room or rooms can be'efiected by any suitable means, and. that the entire device may be used either with or without a light meter if desired. Excellent results however may be obtained from the general construction and arrangement herein disclosed and this disclosure may therefore be considered as the preferred.
comprising a housing whose interior constitutes a miniature room, said housing having a peep-hole through which the room may be viewed, removable wall elements providing changeable interior decorations for said room, and means for illuminating said room.
' 2. A demonstrator for lighting effects comprising a housing whose interior constitutes a miniature room, said housing having a peep-hole through which the room may be viewed, changeable panels in said housing forming the sides of the room, and means for illuminating said room.
3. A demonstrator for lighting effects comprising a housing having a removable top, the interior of said housing having vertical guides, changeable panels held by said guides and slidable upwardly therefrom when said top is removed, said panels forming thewalls of a miniature room, and means for illuminating said room, said housing having a peep-hole through which said room may be viewed.
4. A demonstrator for lighting effects comprising a housin having a removable top, the interior of sald housing having vertical guides, changeable panels held by said guides and slidable upwardly. therefrom when said top is removed, a removable ceiling panel coacting with the aforesaid panels in forming a miniature room, said housing having a peep-hole through which said room may be viewed, and means for illuminating said room.
5. A demonstrator for lighting effects comprising a housing whose interior constitutes a miniature room, said housing having a peep-hole through which the room may be viewed, removable wall elements providing changeable interior decorations for said room, means for illuminating said room, and a light meter in said room visible through said peep-hole.
In testimony whereof I have hereunto set my hand.
WILLIAM H. LEFFINGWELL.
