Application filed March 24,1924. Serial No. 701,491.
To all whom it may concern: a
Be it known that we, GEORGE MATTHYSSEN and CHARLES OHLSON, citizens of the United States, residing I at Inglewood and Los 'Angeles, respectively,.in the county of Los Angeles and State of California, have invented new and useful Improvements in Headlights, of which-the following is-a' specification.
consists of the novel featuresherein shown,
described and claimed. V
An object is to'makea headlight having a reflector made in two pieces meeting on a A horizontal diametrical' plane, mount one mg in the direction indicated by the arrow 1 in Fig. 2. V
Fig. 2 is a vertical diametrical sectional detail upon an enlarged scale and "taken upon the line 2-2 of Fig. 1. I
Fig. 3 is a' fragmentary sectional detail on the line 3-3 of Fig. 2.
' The details of the headlight shown in the drawings are as follows:
The lower half 1 of the reflector is rigidly 4 mounted in the lamp structure in the usual way, the upper edge 2 of the lower half-1 being in a horizontal-plane and there being a flange 3 extending outwardly from this upper edge 2. A guide wall 4 extends from the flange 3 on one side upwardly around to the flange 3 on the other side, said wall being concentric to the axisof the lamp and straight on planes parallel with the axis.
I A stop'flange 5 extends inwardly from the inneror rear edge of the wall 4. The upper half 6 of the re ector has a lower edge resting upon the flange 3 and the outer circular edge of the half reflector 6 fits the inner face of the wall 4 all the wayaround from Our invention relates to headlights and.
one flange 3 to the other flange 3 and the stop 5 limits the inward movement of the half reflector 6.
A connector sleeve 7 has alamp socket 8 fitting therein,.a'n arm 9 attached to the .co'nn'ector sleeve. slides in the slot 10 of. the tube 16, which latter is rigidly secured to the outer casing 12. A screw 11 passes through the casing 12 and has a threaded engagement with the arm 9. A compression sprlng 13 surrounds the screw and is positioned between the arm 9 and the inner side of the casing 12. This takes up any looseness' A cotter pin 14 through the screw 11 prevents complete withdrawal of the screw out of the arm 9. An electric lamp 15 is inserted in the connector sleeve 7 and-forms contact with the socket 8 in the usual manner. A headed screw 17 is inserted loosely through the outer casing 12 and through'an expansion spring 18 and ta ped into a nipple 19 extendingfrom the liack side of the half reflector 6 near the half sleeve 16, so that by manipulating the screw 17 the half reflector 6 may be moved forwardly, or backwardly to the limits of the annular wall 4. 1
By adjusting the lamp socket 8 forwardly or backwardly the projected rays of light 20 may be'reg'ulatedto an desired angle within reason and are pre erably directed forwardly and downwardly. Then by manipulating the screw 17 and adjusting the half reflector 6 forwardly or backwardly the angles of the projected rays of light 21 may be varied and preferably are directed forwardly and downwardly at a eater angle than the rays 20 so as to mix with the rays 20 at a distance in front of the headlight.
ing a stationary lower half reflector, an adjustable lamp, and an adjustable upper half may be concentrated or' s readas desired,
Thus, we have produceda headlight havand that the direction of t e projected ra s relative to the level ofthe roadway may accuratel factoryg reless headli ht.
Various changes may parting fromaher'spirit of our invention as set up in the claims.
adjusted so as to make-a satismade without de- We claim: y l. A headli ht construction comprlsing a casing adapte t0 suport a lens and'reflector,
a tube mounted through the center of'the casing, a connector sleeve slidinglymoun'ted in the tube, a lamp socket in the connector sleeve, an arm extending from the'connector sleeve through a slot in the tube, a screw inserted through the casing, through an exp'ansive spring and screw seated through'the arm so that by manipulating the screw the connector sleeve may be moved for: wardly or backwardly, a lower half reflector rigidly mounted in the casing andf extending. from the forward end of the connector sleeve, an upper half reflector slidingly mounted upon the tube, a screw insert-y ed through the casing and connected to the upper half reflector and an expansion spring upon the screw so that by manipulating the screw the upper half reflector may be moved forwardly or ba'ckwardly.
2. A headlight construction comprising acasing adapted to support a lens and reflector, a tube mounted through the center of the casing, a connector sleeve slidingly mounted in the tube, a lamp socket in the connector sleeve, an arm extending from the connector sleeve through a slot in the tube, a screw inserted through the casing, through an expansive spring and screw se'atedthrough the upper edge of the lower half reflector being on a horizontal plane, -a flange extending outwardly from this upper edge, a guidewall extendin g from the flange on one side upwardly-around to the: flange on the other side, said wall being concentric to the lamp and straight on planes parallel with the axis, astopflange extending inwardly from the ,inner or rear edge of the guide-wall, an
upperthalf reflector having its lower edge resting uponthe flange and the outer circu-- lar edge fitting the inner face of the guidewall and the mward movement of the half reflector being limited by the stop flange,
.and'slidingly mounted upon the tube, a screw inserted through the-casing and connected to the upper half reflector and an expansion spring upon the screw so that by,
manipulating the screw the upper hall reflector may be moved forwardly or backwardly.
In testimony whereof wehave signed our names to this specification. A
