'LAMP-POSITION CONTROLLER.
Specification of Letters Patent.
Patented May 16, 1922.
Application filed June 28, 1920. Serial No. 392,170.
This invention relates to a lamp position' controller.
It is particularly applicable to lamps or spot lights to control the movements thereof in a plurality of planes. One such application is to lamps of the Stewart Warner type, but it is not limited to such use.
One of the objects of this invention is to provide means for limiting the movement of a lamp or spot light to confine the reflected rays within a pre-determined area.
Another object is toprovide means adapted to be applied as a unit to a spot light in common use, without requiring extensive alterations, for limiting the vertical movement of the lamp within 'a pie-determined an le of a horizontal plane.
Znother object is to provide a simple attaohment of few parts adapted to be applied to a lamp to limit the movement thereof to confine the rays within a given zone when projected forward of the vehicle so as to eliminate objectionable glare.
Another object is to provide means to limit the vertical movement of a lamp when in road illuminating position, but to permit unlimited movement of the lamp for other positions.
A further object is to provide means particularly adapted to be applied to a Stewart Warner lamp to so control the movements thereof as to prevent objectionable glare to pedestrians, and occupants of approaching vehicles.
Other objects and advantages will hereinafter. appear.
The lamp position controller has the following advantages:
It forms a unitwhich is both compact and of few parts.
It may be readily applied to lamps already in use. 7
' It can be attached to the lamp so as not to be readily visible, thus aiding its efficacy and'not detracting from the pleasing appearance of the lamp.
7 It ma be readily and economically manufactured i No extensive alterations need be made in the lamp when attaching the position controller.
An embodiment of the invention is illustrated in the accompanying drawings, in which i Fig. 1 is a front elevation, partly in section, of a spot light support with the lamp in road illuminating position;
Fig. 2 is a developed elevation on the line 22 of Fig. 1, showing the lamp position controller adjusted to restrict the vertical movement of the lamp;
Fig. 3 is a view similar to Fig. 2, showing the lamp position controller adjusted to permit unrestricted vertical movement of the lamp in non road illuminating position;
Fig. 4 is a perspective of the lamp position controller;
Fig. 5 is a side elevation, partly in section, of the lam and support, on the'line 5-5 of Fig. 1; an
Fig. 6 is a broken section of the end of the yoke and the lamp casing.
The invention in general comprises a lamp controlling "means including a cam or notched member movable with the lamp in one plane, another cam or notched member movable with the lamp support and means co-operating with said members to determine the movement of the lamp under pre-determined 1 conditions to limit the movementof the lamp in a vertical plane when the lamp is in a road illuminating position.
Alam or spot light 1 is rotatably mounted on a yoke 2, which is preferably pivotally mounted. on a suitable bracket arm 3. The bracket 3 may be mounted on any suitable standard 4 such, for example, as one of the uprights for the wind shield.
The lamp 1 may be moved in a vertical plane about its horizontal axle of support, and may be bodily moved in a horizontal plane about the vertical supporting axis of the yoke 2.
It is desirable that the movement of the grees on either side of the direction oftravel.
The vertical movement of the lamp should preferably be so restricted that the glaring rays of light will not be projected forward of the vehicle more than a certain distance,
such, for example,: as 40 to 70 feet.
angle in a horizontal plane.
When the lamp is out of road illuminating position there is no possibility of the rays of light therefrom being projected into the eyes of the occupants of approaching vehicles, and its vertical movement should be unrestricted to permit the proper illumination of objects along the side of the road.
The movements of the lamp 1 may be controlled by providing a cam or notched memher 5, movable with the lamp, another cam or notched member 6, movable with the yoke 2, and an intermediate stop or control link 7 operatively associated with the cams 5 and 6'. The functioning position of the link 7 is dependent upon the relative position of the two cams, or in other words, upon the relative position of the lamp and yoke. The construction and relative arrangement of the cams 5, 6 and the link 7 should be such that -within a pre-determined angle of a horizontal plane, the movement of the lamp in a vertical plane is restricted.
. The cam 5 is suitably mounted on the casing of the lamp as by rivets 9 (see Fig. 6) but any other suitable means may be provided for mounting the cam 5 so that the movements thereof will correspond with those of the lamp 1. The lamp 1 is rotatively supported in the yoke 2 by means of screws or rivets 10. A nut 11 cooperates with each screw or rivet to hold the parts in proper relation.
The cam 6 is attached to the: yoke 2 by rivets 12. The yoke 2 is rotatably mounted on the bracket 3 by a stud 13. The threaded end of the stud shank engages the, cam 6, and a washer 1 1 cooperates therewith to hold the bracket 3 and the yoke 52 in spaced relation. Other means may, of course, be employed for attaching the. cam 6 to the yoke 2so that the two may move together.
The control link 7 is mounted on the yoke 2 and is preferably formed oi wire, rod or other suitable material of suflicien t stiffness to resist. bending under compression. The yoke 2 carries guides 8 for the link 7. One end ot: the link 7 is maintained in engagement with the cam 6 by means of a coiled spring 16 encircling the link 7. @no end'ot the spring is. fastened to the' link and the other; is seated against the guide 8.
For thepurpose of reducing the friction between the link 7 and the cam 5, a roller 17 is mounted on the end of the link 7.
For the purpose of restricting the move mentof the lamp 1' in a vertical plane, when the lamp ismoved through a certain angle 0t horizontal plane, the respective cams 5an'd 6-are provided with suitable co-oper artingaraisedor notched portions, The cam 6': is=pirovi ded with a raised portion 18 which prevents=the movement ot' the link7, While the" yoke 2iislbeing'moved through a certain I The" cam 5 is provided with. a' raised portion 19, the
