Specification of Letters Patent. Patented Aug, 27, 191g,

Applicata@ mea April 24, 191s. A, serieu Nt. sabes,

'following is a specication.

This invention has reference more particularly to head lights which are provided with means whereby the direction in which the light is projected may be adjusted, and is particularly applicable to the headlights of automobiles, although its use is notnecessarily confined thereto, but it may be used in any case where it is desired to adjust the direction in which the light is projected.

The object of this invention is to provide means for changing the direction in which the light is projected without moving the entire lamp structure, such means being capable of operation at the lamp or at a distance therefrom.

A. further object is the provision of adjustable reflecting means which may readily be mounted in the standard headlight without diculty,v and which does not require a @special lamp structure to use.

A further object is the construction of an attachment for standard head lights for changing the direction of projection of the light, said attachment being designed so that all .thevworking parts are mounted on the attachment in complete working condition so that the attachment maybe inserted in position in the lamp, complete and ready for operation without the necessity of connecting any of the working parts lto the lamp' casing or structure and making adjustments incident thereto.

A further object is the mounting of the movable parts of the reflecting means, by

- means of a spring holderso that the movable parts are held firmly imposition at a tension so as to take up any wear and also prevent rattling which is likely to develop it otherwise held, particularly when used on vehicles.-

A further object is the use of exible means for communicating control to the lamp, such means being employed so as to permit twisting and straining incidental to the use of the lamps on vehicles, without aHecting the operation of the controlhng means, and. also `\being employed so as to enable the lamp and controlmechanism to be readily and easily mounted without complicated control mechamsm. rI he invention also has other objects which will appear from the following specicatlon and which are particularly pointed out in the claims. In the accompanying drawings which illustrate my invention Figure l is a sectional view, the upper half of which is taken on the line A-A of Fig. 2, and the lower half of which is taken on the line B-B of Fig. 2; Fig. 2 is a fragmentary view of the rear ot" the reflector4 showing the manner of mountlng the movable reflector on the supportlng rim or shell; Fig. 3 is a view of control levers which may be provided for operating the reflector; Fig. 4 a sectional view taken on the line C-C of Fig. 3 showing the manner in which the control levers are mounted on the dash of an automobile; Fig. 15 is a rear view of the control levers showing the lever arms which are provided on the opposite side of the dash for connection to the control wires; Fig. 6 is an enlarged view taken substantially on the line D-D of Fig. l showing the manner of connecting the control wires to the reflector; and Fig. 7 is a sectional view taken on the line E-E of Y Fi 6. l

, n the drawings, l represents the usual outer shell or lamp body with which headlights are commonly constructed, and 2 the door frame which is usually hinged to the shell l and may be opened to'provide access to the interior'of the lamp. This door frame has an annular abutment 3 against which the glass 4 isjset and there is an annular groove 5 in the frame 2 immediately back of the annular abutment 3 into .which a securing the stationary part to the said flange, and means for supporting the adjustable reector on the stationary part so that the reflector isA universally movable.

3. In a device of the class described the combination of a lamp body, a yremovable reflector structure in said lamp body comprising a movable reector and means for supporting said reflector so as to be universally movable, means mounted on said structure and operating independently of the lamp body for moving the reflector, and means for detachably securing the reflector structure in the lamp body.

1l. In a device of the class described the combination of a lamp body, a removable reflector structure in said lamp body comprising a stationary part, means for detachably securing the stationary par-t to the lamp body, a movable reflector, means for supporting the said reflector on the stationary part so as to be universally movable, and means for operating the said reflector said means having a bearing on the said stationary part and a power member attached to the movable reflector.

5. In a device of the class described the combination of a lamp body, a stationary part, means for detachably securing the stationary part to the lamp body, an adjustable reflector, means for supporting the adjustable reflector on the stationary part so that the reflector is universally movable, a tubular member mounted on the stationary part and an operating member movable lengthwise in the tubular member and connected to the movable reflector.

6. In a device of the class described, the

fixed part, and resilient means for holding the movable part of said reflector in operaet tive position upon the fixed part of said reflector.

7. In a device of the class described, the combination of a lamp body, a reflector in said lamp body comprising a plurality of parts, one of which has universal bearing with respect to the other, and co-acting means on said reflector parts for yieldingly holding said rellector parts in operative engagement with each other.

8. In a device of the class described, the combination of a lamp body closed at one end by a substantially flat glass, a reflector in said lamp body back of said glass, said reflector comprising a plurality of parts,60 one of said reflector parts being fixed With respect to the lamp body and the other reflector part being universally movable on said fixed part, and coacting means on each of said reflector parts for limiting the universal movement of said movable part of the reflector on said fixed part of the reflector.

9. In a device of the class described, the combination of a lamp body, a reflector in said lamp body comprising a plurality of parts, one of said reflector parts being fixed in but removable from said lamp body and the other reflector part being universally mounted on the fixed part of the reflector, an actuating device located at a place remote from the lamp body, a flexible casing extending from Within said lamp body to said actuating device, and means in said flexible casing operatively connected at one end to the universally movable part of the reflector and at the other end to said actuating device.

In testimony whereof I have hereto axed my signature.
