LAMP,
Appueaaon mea may 25, 1927. semi No.. 193,973.
My invention relates to lamps and more particularly to a lamp having means for reducing the brilliancy and changing the color of the beam of light emitted therefrom.
Among the objects of 'this invention 1 s the production of a lamp having means for interposing light screens between the lamp and the lens, a demountable unit for carryingthe light screens and an improved type of Casin These objects, and other advantageous en s which will appear hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which u Figure 1 is a central vertical cross-sectional view through a preferred form of my invention, drawn to a larger scale than are the other views, and showing one of the lightscreens in raised position.
Figure 2 is a front view of the lamp shown in Figure 1, the front of the casing and top hood being removed and the light screens inv lowered position. D
Figure 3 isa vertical cross-sectional vlew taken substantially on line 3 3 on Figure 1, but showing thelight screens in lowered position,
Figure 4 a sectional plan view, taken substantially on line 4 4 on Figure 1 but showing the light screens in lowered position, and
Figure l5 a perspective view of the light screen unit.
VFigure 6 is a plan view and Figure 7 an enlarged edge view ofthe chain operating means used in conjunction with my improved lamp.
Figure 8 is a front view of an automobile upn which my invention has been installed, an
Figure 9 an enlarged fragmentary lside view of same, certain parts being broken,
away and the motor omitted in order to show the lamp which is mounted upon the left side of the vehicle and to illustrate the manner in which the operating chains may be connected to the operating means mounted upon the dash of the vehicle.
Referring now more in detail to the drawings, the lamp casing has a bottom 10 to ywhich side walls 11 and 12 and a suitable bracket 13, for supporting the lamp, are secured. A frame 14, bent to conform tothe cross-sectional outline of the lamp easing, is
secured to the bottom and side walls, in any desired manner and is adapted to have the top 15 secured to its upper part by means of suitable screws 16 so that top 15 may be read- -ily removed from thelamp casing in order to provide access to th-e interior thereof.
Each edge of top 15 extends beyond the side wall and has secured thereto a U'-shaped guide member 17, one leg of which is adapted to abut the side wall of the lamp casing and the other leg forms a guideway for a hood 18. The front part of hood 18 is provided with a downstanding iange 19, adapted to give the front of the lamp casing a finished appearance, and the rear of hood 18 abuts the casing back 20 which extends above the top 15 and is rounded to conform to the outline of hood 18. Casing back 20 is slidably mounted in guideways 21, formed on 'the rear edges of- side walls 11 and 12, and is provided with a cable conduit 22, adapted to accommodate electric wires 23 through which current may be supplied to an electric lamp 24 mounted in the lamp casing as will be described later, and with a slot 22ZL aligning with conduit 22 so that the casing back may be removed from the lamp casing without dis` turbing wires23.
A plurality of screen frames 25, each of which may have a differently color-ed glass 26, vare slidably mounted in guides 27; the guides at each end of frames 25 being preferably secured to one another by braces 28 and each' set of braces so secured together are preferably secured to one another by U- shaped fram-es 29 which are ,adapted to be secured to bottom 10 and top 15 by screws 30. fThe front of the lamp casing is closed by a front part 31 composed of an inner plate 31a, slidably mounted in a guideway 32 secured to side wall 11 and in a guideway 33 secured to one of the screen guides 27, and an outer plate 31", which isflanged at its edges to form corners 34 slidable on the outside of side walls 11 and 12. The upper part of front I part 31 Ais apertured and provided with an outstanding circular flange 35 in which a lens 36'is secured in any suitable manner as by a rim 37.
A light bracket 38 is secured to top 15 by*y means of an internally threaded nut-39 and supports a light.- housing 40 in which a lamp lens 42; light bracket 38 being so disposedI` 24 is mounted in the usual manner and which is provlded with a. reflecting surface 41 and a,
v lamp, I 1y drawing that lamp' 24 -is positioned directly behind lens 36.A y' y A' From the foregoing, it will be evident that access may be readily had to any part of the or the lamp casing dismantled by merev hood 18 forwardly, raising casing back 20 and front part 31 out of their guide.- -ways and, shouldf it be desired, removing the i screen unit from the interior of the casing by` merely removing screws 30. Light housing 40 may also be removed from the lamp casin by merely unscrewing nutY39 froml light racket 38.
An extension 43 is secured to the bottom of each screen Iframe and has one end of a chain 44 secured thereto; chains 44 extendingupwardly over deflector sheaves 45 and .l out of the lamp casing through suitable aperthe .radiator shell 46 and pass between its" flange and the core of the radiator (not Ashown).. From this point, they pass close to the side of the hood 47 and through the dash, 48 where they are secured to operating levers 49 hinged in brackets 50secured to the d ash. When it is desired to raise one of the ligglltscreens, the lever 49 connected therew1 1s the center of each chain 44 so that the chains may be separated at this point and each part of the chain swungout of the way. A
While I have describedmy invention as,
E taking a particular form, vit will be underters ing back slidable therein, front guidewafs stood that modifications may `be made without departing from the spirit thereof, and hence I do vnot limit myself to thel precise construction set forth, but consider that I am' at liberty to make such changes and alterations as fairly come within the scope of the appended claims.
