To all 2117mm it may concern.-
Be it known that I, JAMES (PROBE, a subject of the Queen .of Great Britain, residing at Mount Vernon in the county of "Westohester and State of I cw York, have invented aceriain new and useful improvement in Devices for Supporting Fixtures, of which the following' is a specification.
The object of my invention is to provide a I0 simple and effective device for hanging electric-light fixtures from ceilings formed of hollow brick and in places where the usual pipe located in an undesirable part of s rooni.
In carrying my invention into clieeti first form a hole through the plasterof thcceilinsr andinto the hollow brick. into tiiis opening I insert a short stem 0;? shanlr having" two cross-pieces at the top, between which are pivo'ted two short arinsheld at right angles to the stem by springs and ,prevented from tilting npivartlt is, above a horizontai linehy reason of the inner eons of the arms resting; on the top of the stem. The two a1 us while the device is beingflnserted into the opening; are forced downward against the pressure oi the springs until close enough to the stem to allow it .to he pushed upward throurrh the openin When the ends of the arms clear the opening they are causedto rise by the spring-pressure and again stand at right anglee to the stem. The two arms will rest on the inside of the holloiv brick and the store will he held in position. The lower end of the stern has an external screw-thread for coupling the main pipe of a lixturo to itwhen used for that purpose, and has also a screwthreaded hole at its lower end for roccivinga screw when it is desired to support a centerpiece or othercovering for the opening before the electriclight fixture is put in place or after the fixture taken down.
My invention isillustrated in the acconipanying drawings, in which Figure 1 is an elevation of 'a simple eleotrio-light fixture embodying my invention. Fig. 2 shows the device while being' inserted into the ceiling. Fig. 3 shcwsthe device, partly in section .anii supporting a center- 0 niece or other covering for ihe onening; and

As the stem (5 is passed up through the opening 0 the arn1sy"are forced c'lownward against the stem (7, and held in such position until the ends of the arms clear the opening 0, when the snrings 5/ will force them upward, so that \vnen the stem (Z is released or drawn down vv'artl the arms 1' will rest on the inside of the hollow brick. The nrxnsfare prevented from rising; above the horizontal position by means of the finger 1T ,exgending from the inner end of each arm, and which rests on he top of the stem (Z.
