LAMP-MOUNTING.

Specification of Letters Patent.

ratented May 22;, 1917.

Application filed November 27, 1916. Serial No. 133,570.

To all whom it may concern.

Be it known that 1, CHARLES E. (looLnY, a citizen of the United States, and residing at Detroit, in the count of iiajurc and State of Michigan, have invented a. new and to supports which lie in vertical planes parallel to the axis o'i the projected light beam of the lamp, and its object is to provide a support which will permit the lamp lo be tilted so as to swing; the light beam up or down in a vertical plane while. preventing it from swinging in a horizontal plane,

This invention consists, in combination with a. lamp and an upright post. of a clamp engaging the post, and a knob on the lamp engaged. by the clamp, said knob and clamp being so constructed that the knob can rcvolve within the clamp on only one axis.

in the iuzcon'ipauying drawing. l igurc 1 is a front elevation of a. lamp secured to one of the upright supports of a windshield. Fig. 2. a plan of the: clamp and of a knob on the lamp body". Fig. 3 is a section of the clamp on' the line 3-3 of Fig. Fig. 4 shows a. modified form of clamp and supporting knob.

Similar reference characters rotor to like parts throughout the several views.

Many automobiles and other vehicles are not supplied with auxiliaryoillamps and it is often desirable to equip these vehicles The upright supports of the windshield have been found very convenient for this purpose and lamps have been con nectedthcreto by means ofball and socket joints. This type of support is liable to permit the lamp to swing down unless made so tight as to render the joint ineffective.

In the present construction, the support 4 of the windshield 5 is engaged by the two clamping members 6 and 7 which are provided with transverse ribs 8 to prevent the clamp from swinging down. A bolt 9 hava nut 10 may be employed to toreethe members 6 and 7 toward eeohother.

Extending laterally from the lamp 12 and preferably in a horizontal line passing is a short post 13 having a plate 14 at one.

end wherebv it is secured to the lamp body,

and a knob 15 at its outer end. This knob is not s 'iherical but of some other shape that permits the knob to turn on onlyone axis. In Figs. 2 and 3 the knob is shown to be substantially ellipsoidal with its axis roru'entric with the central line of the post 13. while. in Fig. l the knob 20 is shown to be cvlindrical. ln-the one ase. it fits in seats between the ribs or jaws 16 on the members ii and T and in the other between the ribs or jaws 1T on'the members 18 and 19.

In this present construction, the top of the lamp can be tipped forward or back so that the beam oi ligrht may be projected at anv dcsirel l angle. lVhen the axis of revolution passes through the center of gravity of the lamp, the lamp has little tendency to swing out of the desired position and a grip of the clamping members sufliciently strong to hold the lamp in place on the support 4 will also prevent the knob from turning between the jaws that position it. The seats on the clamping members prevent the knobs from turning, on more than one axis.

I claim:

fl. In a lamp mounting, the combination of a pair of clamping members and a lamp having a projecting post and :1V knob on the end of the post of larger diameter than the post, said clamping members having seats to receive and permit rotation of the knob which is bounded by any surface of revolution other than a. sphere, the seats extending around the knob to engage its sides and preventing the knob from turning on more-than one axis, and a. boltto draw the clamping members against the knob.

2. In a. lamp mounting, the combination of a pair of clamping members and a lamp hav ng an ellipsoidal knob, sa1d clamping members having seats to receive and permit rotation of the knob. the knob and seats being so formed as to prevent'the knob from turning on more than one axis, and means to secure theclamping members to a support.
