FOG LAMP WITH AMBER BULB SHIELD HAVING MAGNETICALLY OPERATED ADJUSTMENT Filed Oct. 8, 1949 IN VEN TOR. Z6 (/WJZP/ 2055' Patented Aug. 7, 1951 FOG LAMP WITH AMBER BULB SHIELD HAV- ING MAGNETICALLY OPERATED ADJUST- MENT Joseph Ruben, Milwaukee, Wis.

Application October 8, 1949, Serial No. 120,237

1 Claim. 1

This invention relates to a fog lamp construction.

It is an object of the present invention to provide an adjustable amber cylinder arrangement to provide a fog lamp shield about the lamp bulb within a head light of an automobile whereby the shield can be adjusted to different degrees of adjustment over the lamp bulb.

Other objects of the present invention are to provide a magnetic arrangement for the adjust ment of an amber sleeve of a head light which is of simple construction, inexpensive to manufacture, positive in action, compact and efficient in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a sectional view of a head lamp with a lamp arrangement comprising an amber shield having a magnetic piece thereon and a series of permanent and electro-magnetic magnets dis" posed therein.

Fig. 2 is an enlarged sectional view of the magnetic arrangement.

Fig. 3 is a transverse sectional view taken on line 3-3 of Fig. 1.

Referring now to the figures, It represents a head lamp casing having a forward lens I l secured to the casing upon a gasket l2 by means of a retaining ring l3 threaded upon the casing ll). At the rear end of the casing is a lamp source It and a magnetic arrangement I5 on the rear of the casing adapted to operate an amber colored sleeve l8 having a soft iron ring I! at its rear end. This ring will be attracted by the different sets of magnets, as for example, electro-magnetic magnets 18 and permanent magnets Hi. The permanent magnets are of such size and shape that they will tend to pull outwardly the amber sleeve l6 by action on the magnetizable ring 11. These permanet magnets l9 are of smaller size beginning with the forward part of the arrangement and increase in size rearwardly whereby to come into play to cause the normal rearward movement of the sleeve and to retain the sleeve IS in its rear postion during movement of the car carrying the headlight. These magnets are of such size and degree of magnetism as to effect this automatic retraction of the amber light sleeve.

When it is desired to place into play the amber light about the lamp source, electromagnets 18 can be set into play by the adjustment of a switch arm 2! over contacts 22 so as to magnetiz the same in sequence and to cause the advancement of the shield forwardly. A battery source 23 is provided t supply current to the electromagnets It. The electromagnets have several turns of wire coil, as indicated at 25, therearound. The magnets increase in size from the rear end of the arrangement toward the forward end of the arrangement, the larger magnets being at the forward end. With the last magnet put into operation, the sleeve will be advanced to the greatest extent within the head lamp casing [0. Each of the electric coils 25 can have a common ground 26, while each of the wires, as indicated at 21, are connected to the terminals 22 over which a switch arm 2| can operate. The battery source will be grounded as indicated at 28.. Uponrelease of the electromagnets, the shield will be automatically retracted. The amber shield will cause, when in its extended position, yellow amber light to be delivered from the headlamp.

While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claim.

Having thus set forth and disclosed. the nature of my invention, what is claimed is:

In combination, a head light casing having a lens connected thereto, a light source connected to the rear end of the casing, an amber shield adjustable over the light source and having a magnetizable member thereon, permanent magnet means actin upon the magnetizable member to normally effect the retraction of said amber light shield, and electromagnetic means operable to cause the forward movement of the shield and acting upon the magnetizable member on the shield, said electromagnetic means comprising a series of electromagnets disposed in the direction of the movement of said shield, said permanent magnets being of varying size beginning with a small size adjacent the casing and with the larger sizes rearwardly thereof, said electromagnetic means being of a series of magnets of varying sizes and disposed in the direction of the movement of said shield, the larger size of the electromagnets being adjacent the end of the casing and the smaller size being disposed rearwardly thereof.
