Headlamp Brackets The Headlamp Bracket Subdivision of the LightingDivision has, in cooperation with the lamp manufac-turers, developed a universal fender type headlampbracket which has been tested and found satisfactoryin actual practice. This bracket has a spherical mount-ing surface for the lamp body, the radius of curvatureof the surface being 2l ■_• in. The lamp is held to themounting surface by a single carriage bolt. The ad-vantages of the proposed construction are twofold: thebracket permits universal adjustment of the lamp aswell as interchangeability of lamps. The proposedbracket is shown in the cut tamp Body Beonng-M/sher Lock Washeri-ZO Hex Nur Carriage 5olfl/i long-i^- 20thd US For nThreaded 7/efrom End posed parabolic headlamp bracket.
