VARIABLE HEADLEGHT DIMMEB.

Application filed November 8, 1926. Serial No. 147,120.

The present invention pertains to a novel attacl'nuent for headlights whereby the rays lSSUlIlg therefrom may be dimmed in a variable manner.

6 The principal object of the invention is the provision of a device of this character wherein the extent of dimming of the lamps may be controlled by a suitable connection reaching to the dashboard of the automobile.

The device comprises essentially a pair of telescopic shield members rotatably mounted with respect to a headlight and adapted to cover the lamp. These members are carried by a shaft, one being fixed. thereto and the other being loosely mounted thereon. By

means of a crank and link connection extending from the shaft to the dashboard, the position of the shield members with respect to the lamp may be varied at will whereby v the amount of dimming is controlled.

The invention is fully disclosed in the following description and in the accompanying drawings in which;

Figure 1 is a vertical section of the device showing the shield entirely raised;

Figure 2 is a detail section showing the shield in its lowermost position;

Figure 3 is a detail section at right angles to Figure 1, showing the connections to the shaft;

Figure 4: is a rear elevation; and

Figure 5 is a perspective View.

Reference to these views will now be made by use of like characters which are employed to designate corresponding parts throughout.

The headlight shown in the several figures comprises as usual a casing 1 containing a reflector 2, a lamp 3 mounted in the centre of the reflector, and a lens 4: secured over the open side of the casing and reflector by means of a ring 5.

To the outer surface of the casing 1 is secured a pair of bearing brackets 6 in which is ournaled a shaft 7. The casing is formed with a curved slot 8 adapted to accommodate ini'ier and outer elbow sections 9 and 10 respectively. The inner section 9 has its ends loosely mounted on the shaft 7 as shown in Figure 8. The outer section 10 is formed at its ends with bosses 11 surrounding the shaft and is secured thereto by set screws 12. Each end of the shaft is provided with an arm 13 normally drawn towards the casing 1 by means of a spring 14 connecting these parts.

The rearward end of the inner section 9 carries a flange 15 adapted to engage the convex surface of the reflector 2 as shown in Figure 2. This member prevents the-inner section from passing entirely through the slot 8. The forward or lower end of the section 10 has likewise a flange 16 adapted to engage the concave surface of the reflector.

flange 15 on the latter. In this manner both sections may be withdrawn entirely from the lamp 3 as illustrated in Figure 1. It will be evident that by means of the link 18 the position of the sections 9 and 10 with respect to the lamp 3 may be regulated to vary the extent to which the lamp is shielded.

While a specific embodiment of the invention has been illustrated and described, it is to be understood that various alterations in the details of construction may be made without departing from the spirit of the invention as indicated by the appended claims.

Having thus fully described the invention, what I claim as new and desire to protect by Letters Patent is:

1. A headlight including a casing, a reflector mounted therein, and a lamp mounted in the reflector, in combination with a pair of telescopic shield members pivotally mounted with respect to said casing and reflector and adapted to cover said lamp a flange provided at the rear end of the inner member, said flange engaging the outer wall of the reflector and being engageable by the rear end of the outer section.

2. A headlight including a casing, a refiector mounted therein, and a lamp mounted in the reflector, in combination with a shaft rotatably mounted with respect to said cas ing and reflector, a pair of telescopic shield members mounted on said shaft and adapted to cover said lamp, the inner member being loosely mounted on the shaft, and the outer member being fixed to the shaft.

3. A headli ht including a casing, a reflector mounted therein, and a lamp mounted in the reflector, in combination with a shaft rotate hly moupted With respeet to said easing and reflector, a pair of telescopic shield members mounted on said shaft and adapted I to cover said lamp, the inner member being loosely mounted on the shaft, the outer memher being fixed to the shaft, a flange provided at the rear end of the inner member, spud flange engaging the outer wall of the 'refleetor and being engageahle' by the rear 10 end of the outer section,

In witness whereof I have hereunto set my
