SHUTTER FOB AUTOMOBILE LAMPS.

Application filed February 28, 1923.

T0 aZZ whom it may concern:

Be itknown that I, LOUIS LECLERC, a subject of the King of Great Britain, residing at Maria, Province of Quebec, Canada, have invented certain new and useful Improvements in Shutters for Automobile Lamps; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention pertains to a novel shutter for automobile lamps and is designed to be operated in a suitable manner from the drivers seat in order to dim the lamps when required.

The device comprises a plurality of overlapping arcuate screens the ends of which are pivoted to opposite sides of the lamp casing. These ends are progressively notched in such a manner that the maximum movement of each screen is such as to form a shutter having a spherical surface when in operative position. To the end of one of the outer members is fixed an operating lever having a tongue extending through the grooves at that side. At the opposite side a stop member is fixed to the lamp and extends through the notches, whereby the movement of the screens is limited.

The invention is fully disclosed in the following description and in the accompanying drawings in which Figure 1 is a front elevation of a lamp having the invention applied thereto in open position;

Figure 2 is a side elevation thereof;

Figure 3 is a section on the line 3-3 of Figure 2;

Figure 4 is a section on the line 1- 1 of Figure 8;

Figure 5 is a sectional view corresponding to Figure 4:; showing the shutter in operative position;

Figure 6 is a longitudinal section through the lamp and shutter, showing the latter in operative position;

Figure 7 is a sectional View corresponding to Figure 3, but showing the opposite end of the device;

Figure 8 is a section on the line 8-8 of Figure 7 Figure 9 is a section similar to Figure 8, showing the device in operative position;

Figure 10 is a perspective view of the outer screen;

Serial No. 621,921.

Figure 11 is a perspective view of the notched ends of the screens at the operating end of the device;

Figure 12 is a similar view of the opposite end of the device; and,

Figure 13 is a perspective view of the stop member disposed at the end shown in Figure 12.

In the above views wherein like reference characters are employed to designate corresponding parts throughout, the numeral 1 indicates a lamp casing within which is contained a reflector 2. A lamp socket 3 extends through the casing and reflector in the usual manner and carries a lamp 4 disposed within the reflector. A lens 5 is set into the reflector, while the edge of the casing is surrounded by a rim 6 bearing against the outer surface of the lens, as shown by the numeral 7.

To opposite sides of the lamp casing or rim are fixed a pair of bolts 8 and 9. These serve as pivots for a plurality of shutters which are adapted to overlap, as illustrated in Figure 6. The ends of these screens are enlarged as at 10 and are superposed at opposite sides of the lamp, the screens in general being indicated from the outer one to the inner one by the characters a, b, o, d, e, f, and it.

These ends are notched progressively at opposite sides of the lamp, the notches at one side increasing in width from the outer screen a to the inner one it forming steps a, b, c, cl, 61, f, g, h. At this end an operating lever 11 is secured to the end of the outer screen a and has a tongue 12 extending through all the notches at this end. The smallest notch is of such width that the tongue engages the opposite sides thereof when the device is in closed position, as shown in Figure 11, the tongue bearing against the edge of the outer step a.

The ends of the opposite side of the lamp are similarly notched progressively, but in the reverse manner, the notches increasing in width from the inner screen it to the outer one a, forming steps of, b, 0'', cl, 6, f, g, It. At this end a disk 13 engages the outer screen a and is fixed to the bolt 9 by means of a nut 9. The disk has a tongue or stop member 14: projecting inwardly therefrom into the notches at that side of the lamp. In the closed position of the shutter, the notch forming the step it is slightly wider than the stop 14, so that the screen it is permitted to move only the short distance indicated in Figure 6 at the end of which its movement is ended. The remaining screens are capable of movement on the pivots 8 and 9, increasing in extent from the inner screen it to the outer screen a, in proportion to the notches forming the steps h. to a.

The lever 11 is provided with an eye 15 to which may be attached a suitableleverage or operating mechanism for turning the tongue 12 from the drivers seat. As the tongue 10 is in the direction of the arrow shown in Figure 2, it first engagesthe step a, moving the screen a the maximum distance until the step it engages the stationary stop 14. Similarly, the remaining steps are successively engaged and turned on the pivots until the double primed steps thereof engage the stop member whereby the device is broughtto the position shown in Figures 5, 6 and 9. v

\Vhile 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 1 screen members, each of said members having its ends pivoted to opposite sides of the lamp, the ends of each side being superposed,

said ends being notched progressively at each 7 side of the lamp, the notches in the ends at through the notches in the ends at said side.

2. In combination with a lamp, a'shutte-r therefor comprising a plurality of arcuatc screen members, each of said members having its ends pivoted to opposite sides of the lamp, the ends of each side being superposed, said ends being notched progressively at each side of the lamp, the notches in the ends at one side increasing from the outer end to the inner one, an operating device secured to said outer end and having a tongue extending through the notches at said side, while the notches in the ends at the opposite side increase from the inner end to the outer one, and a stationary stop member fixed to the lamp and extending through the notches at said opposite side.

In witness whereof I have hereunto set my hand.

LOUIS LECLERC.
