When desired, the lamp bulb can projected beyond the rellector by ine-ely loosening the set screw 34e and sliding the tube 33 and subsequently tightening the y screw. it is apparent, therefore, that the lamp bulb can be placed in 'practically any desired position.
`lt is believed in script-ion that a further View of the foregoing^ detailed desc-.
of the operationeof invention is entirely unnecessary. Likewise it is thought that the advantages of the invention are readily ap parent.
Having thus fully described tiis inverty tion, what is claimed as new and desired to be secured by Letters-Patent is:--
l. device of the character described the slot in The tube 17 may 'I limitinf partial rotatable move- Ioi' the tube.

A device of the character 'described including a pair of telescopically engageable tubes partiallyrotatable with respectl to each other and one of which is universally mountpoints of the head, tiunnions'projeting een A ed, a yoke carried by the outer end of the other tube,- radiallyserratedears formed at the terminals of the yoke, a-reflector formed 'with a head, oppositely disposed and' ra4 dially serrated bosses formed on opposite trally from the bosses for engagement throu'gh the ears for swingingly supporting the head Iin the yoke, the resiliency ofthe yoke assuring of the yielding engagement of the ears with the bosses whereby the headY may be maintained in different positions .of
angular` adjustment with respect to theyok, a lamp bulb' mounted in the head, and conducting -wires oppositely arranged in the head and through the tubes.
In testimony whereof I affix my signature.
