The :spring tl llO l wholly separated from the support.

It will be understood that the longitudinal extension of the support serves not only the purpose of developing end thrust which holds the lamp in position, but it adapts the device for use between walls of varying distances apart. In order to increase the range of application thus secured, the device may, if preferred, be provided with two exten- .sible ends 5, as shown in Fig. 5.

I do not limit myself to the use ot a resilient thrust-developing` means as it will be understood upon reference to Fig. (5 that this result may be ineasurably realized (especially where special means are provided ior increasing friction). by employing a screw threaded connection l, 5l between the sleeve 5 and the tube l as shown. In using the screw thread however, I would prefer to construct the head 5 with spurs 5f and to have the head 5E* rotatable in the sleeve 5 so that the spurs could be embodied in the sustaining wall by:rotating the sleeve 5.

Having thus described my invention, what I claim as new therein and desire to secure by Letters Patent is l. An adjustably self-supporting lamp tor illuminating a restricted area comprising a tubular lamp inclosing and supporting member having a restricted exposure opening, and having means by which to develop end- Wise thrust adapting it to sustain itselit in angularly adjustable position between two opposed faces.

2. An adjustably self-supporting lamp tor illuminating a restricted area c nin rising a tubular lamp inclosing and supIun'tingmember having a restricted exposure opening, a lamp supported therein in position to emit its light through the exposure opening, a tubular member extensively mounted in telescoping relation to the lamp containing` and supporting member, means or developing an I.endwise thrust of the extension member relatively t0 the lamp inclosinfg` and supporting member, and abutting ends provided on the structure to adapt it to sustain itsel't in angular-ly adjustable position between two opposed faces.

3. In a lamp of the character described, the combination ot a tubular support having an exposure opening, as lamp tilted in said. support in position to emit its light through the exposure opening, and means tor frictionally supporting said lamp between opposed walls and pern'iitling ot' its angular adjustment therein whereby to direct' the rays ol light emitted through the opening, l. An adjustably self-supporting lainp comprising a main tubular lamp inclosing and supporting section having' an exposure opening in one side thereof, a lamp supported in said section in position to emit its light through said opening, an extension member telescoping with said main tubular section, and means contained within the main tubular section and the telescoping extension, for developing end thrust.

5. An adjustably. self-supporting lamp comprising' a main tubular lamp inclosing and supporting section having an exposure opening in one side thereof, a lamp supported in said section in` position to emit its light through said opening, an extension member telescoping with said main tubular section, and means contained within the main tubular section aud the teleseoping extension, for developing end thrust; said main tubular member being provided with a transverse wall separating the lamp containing portion trom the portion which contains the thrust dewloping means and forming an abut-ment for the latter.

.ln a lamp ot' the character described, the combination ot a main tubular section having an exposure opening in one side thereof, a. lamp supported in said section in position to emit its light through said opening, and a spring pressed sleeve fitted on one end ol said tubular section and coperating with the other end thereof to hold the device in frictional engagement between opposed walls and permit of its angular adjustment, whereby ito regulate the direction oit the rays of light emitted through said opening'.

T. A lamp support comprising a tubular body, a sleeve telescoping upon the end thereol", a spring abutment secured in the tubular body, a head secured in the sleeve, and a spring introduced between said abutment and head and forcing the sleeve outward relatively to the tubular body; said tubular body and sleeve being constructed with interengagiug slot and pin limiting means.

8. YIn a lamp oi the character described, the con'ibination of a tubular support, a lamp carried by said support and adapted to enter the same from one end, and an end closure for the end ot' the support through which the lamp is introduced; said tubular support and end closure being provided with a recess to'recei ve an electric conductor leading to the lamp.
