J. FOELL I LAMP SUSPENSI ON Filed May 26. 1926 Patented Mar. 13, 1928.
UNITED STATES J'OSEF FOELL, O1 DUSSELDOBF, GERMANY.
LAMP SUSPENSION.
Application filed. May 28, 1926, Serial No. 111,794, and in Germany May 28, 1925.
This invention relates to a suspension for electric lamps and ot the kind composed of an endless flexible element which is guided in the reflector and in a support carried by the lamp wire so as to allow the reflector and lamp to be adjusted thereon and maintained in different angular positions.
The object of the invention is to produce a neat and serviceable arrangement, and the invention consists in suspending the reflector from a support in the torm ot a bell having a tubular rim adapted to receive the flexible suspendii'ig element, the rim being slotted to admit said element.
The segmental, horizontal guide tubes formed on the bell for the chain or cord, will be able to hold the latter securely in any desired position without offering much resistance to the adjustment of such chain or cord when relieved of the load.
Fig. 1 of the accompanyingdrawings represents a side view of the arrangement with symmetrically suspended lamp,
Fig. 2, a similar View partly in section,
Fig. 3. a side View showing the lamp suspended in an angular position, and
Fig. 4, a cross-Section taken through the lamp support.
An electric lamp, which is connected to a reflector a in the usual manner, is suspended from a support f which is preferably connected to the lamp wire 9. The support 7' has the form of a bell the rim c of which of tubular shape so that it can serve as a guide for a flexible suspending element 6 such as a chain, cord or the like. The reflector a is fitted with eyelets (Z, and the rim 0 with a corresponding number of apertures 6 so that a single length of chain or cord 7) can be threaded through the different eyelets (Z, through the apertures 6 and through the intermediate rim portions. as shown in Fig. 4-. The chain may be endless or the ends 01" the same may be connected to one of the eyelets (Z or to a point on the bell rim 6. In either case it allows of adjustment so that the directive lengths of the different suspending stretches can be varied for supporting the lamp either in a symmetrical position as shown in Fig. 1 or in an angular position as shown in Fig. 3. Thus the lamp can be adjusted so as to throw the light in any desired direction and at any suitable angle. I
The adjustment is easy, and the frictional engagement of the chain or cord with the guide elements is suflicient to nniintain the lamp in adjusted position.
I claim:
The combination with an electric lamp and its reflector, of a bell carried by the lamp wire, said bell being formed with a tubular rim divided by slots into segments, a plurality of eyelets connected to the reflector, and a flexible suspending element threaded through said eyelets and through different segments oi the bell rim so that it can be adjusted. therein "for holding the reflector and the lamp suspended from-the bell in difii'crentangular positions.
JOSE]? FOELL.
