1 Claim.

This is a divisional application from the original filed on November 11, 1936, under Serial No. 110,324, for Head lamps for vehicles, now Patent No. 2,123,125, dated July 5, 1938.

My invention relates to head lamps for vehicles.

Among the objects of my invention are to supply a construction Ifor the adjustment and positioning of the housing in any desired position; to provide an adjustable connection whereby my head lamp may be attached to a vehicle in any desired position; to supply such a connection that will have a construction that my head lamp will be theft proof, and such other objects, advantages and capabilities as will later more fully appear and which are inherently possessed by my invention.

While I have shown in the accompanying drawing a preferred embodiment of my invention, yet I wish it understood that the same is susceptible of modification and change without departing from the spirit of my invention.

Fig. 1 is a side sectional view my head lamp; Fig. 2 is a front View of the same; Figs. 3 and 4 are detail views of my peculiarly shaped and formed wrench; Fig. 5 is a detail View of the adjusting means for my lamp.

Referring more particularly to the embodiment selected to illustratemy invention, it comprises a head lamp I having a housing II, a lens I2, an electric light bulb I3 connected to an electrical source of supply and a reflector I4.

Adjacent the bottom of my housing I I a flange socket 25 is fixed by rivets or other lsuitable means. Said flange 25 has at its forward portion an upwardly curved lip 26 to receive the central lower portion of the lens retaining ring I9. 'I'his lip 26 acts as a guide and holding member for the ring I9 during the operation of assembling when the ring is being contracted and the cap 23 is being placed thereon. Later the lip acts as a secondary support for the ring I9. Said flange socket 25 has substantially at its center a concaved portion 21 having anl aperture 28 to receive a bolt 30 of ball washer 29. Said ball washer is of a smaller or equal radius than the radius of the concaved portion 21, and its edges are adapted when so positioned to co-ntact the concaved portion. The ball washer 29 may be adjusted by turning of bolt 30 so that the edges of said washer dig into the concaved portion 21 of flange socket 25 so as to securely hold the lamp I0 in any desired position to which it has been placed by the user. 'I'his construction permits easy and exact positioning of my lamp without the creeping that has heretofore been present when adjustment was being made. My construction also insures a permanent positioning once the lamp has been adjusted intoplace.

My supporting arm 3| has an upper curved portion 32 adapted to t under the concaved portion 21 of the flange socket 25. The bolt 30 passes through the upper concaved portion 32 of the supporting arm 3|, and the said concaved portion extends downwardly on either side of nut 41 of bolt 30 forming a recess 5I so that said nut may only be reached and turned by head 46 of my wrench 82 having the peculiar shape necessary to enable it to pass into said recess I, thus making said adjustment theft proof. The supporting arm continues with a downwardly and outwardly curved shank 33 to end in a serrated bottom 34. The shank 33 has a hollowed out portion 35 towards its lower end so that the head 36 of the bolt 31 cannot be reached and turned except by head 48 of wrench 32 peculiarly shaped to reach into said hollowed out portion 35 of the shank 34. This construction again makes the same theft proof as it cannot be tampered with by the usual run of wrenches, but requires a peculiar tool created for the particular job. Said bolt 31 secures said supporting arm 3| to a standard 38, there being teeth 39 on the standard adapted to engage the serrated bottom 34. 'I'he standard 38 is attached to the bumper or other suitable supporting member 40 of a vehicle by means of a clamping plate 43 held by a pair of spaced bolts 4I. Said bolts are positioned in recesses in said plate 43 and are surrounded on three sides of the wall of the plate so that they are accessible only by head 4B of my peculiarly shaped wrench 82, adapted to enter into said recess for turning said bolts. This is the third theft proof feature of my lamp. Inasmuch as the supporting arm is movable in a horizontal plane in any direction and the lamp housing is movable in any direction horizontal or vertical, the lamp itself may be placed wherever desired on the vehicle to protect it from accident and yet to give most efficient service. A set screw 42 cuts through the enamel of the bumper 40 to permit proper electrical contact and to obtain a maximum ow of electricity.

Having thus described my invention, I claim:

A supporting arm for attaching a head lamp to a vehicle comprising an upper portion adapted to contact the head lamp, and a lower portion adapted to contact the vehicle, both of said upper and lower portions curved to form tapered recesses, means in the upper of said recesses for attaching the supporting arm to the head lamp, and means in the lower of said recesses for attaching the supporting arm to the vehicle, said means being reachable only by means conforming to said recesses.
