Fastening illuminating bodies to and suspending them from, ceilings, that is to say, from the hook provided in a suitably located ceiling beam, irrespective of whether the illuminating body to be suspended is an eggshaped pendant or a spring-actuated illuminating body or any other illuminating body of the before-mentioned types which is suspended by the intermediary of tubes or chains or a cable, necessitates a certain definite space between the respective body and the ceiling. This space is necessary that the fitter may have access to the ceiling beam or hook from which the illuminating body is to 1 be suspended, but the space mentioned affects the good apearance of the illuminating body, and another undesirable feature is that dust collects upon the upper surface of the top member.

The drawbacks hitherto experienced with the known devices of the kind in question and for the purpose stated are completely done away with, according to this invent1on, by the features that the suspension device proper for the illuminating body is arranged in the lower of two hollow cylindrical members,

upon which lower member the upper member is telescopically movable, that is to say, the upper one can be depressed over the lower member. Thearrangement and combination of the parts is such that the fitter is enabled to eflect the fastening andthe suspension' in a very convenient manner; at the same time the above-mentioned space above the top member is no more visible, in that it is covered or closed by the top member designed according to this invention.

The invention is illustrated diagrammatically by way of example in the accompanying drawing in which Figure 1 is a perspective representation of a top member designed according to this invention, a part of its circumferential wall being broken away in order to show the interior construction. Figure 2 is a vertical section through another constructional form, and Figure 3 is a sideview of still another constructional form,

Figs. 2 and 3 being drawn to a reduced scale.

The improved top member consists of two telescopic parts 1 and 2, of which the lower pm '(2 is intended to be alfixedto'the ri' spectlve ceiling, thatis to say,tolthe' hook screwed into a suitably located beam sameqTh'ehook (notjshownlextendsint the FOP-mem er 'througli h "tart t Ii fi .55 where there is in this part an 'eye'Skthat' iisf'to be? hung into] the hook so: as tof be coupled with the same.

the ring 6 being theudispensedwith. Also the spring '3 maybe replaced by an 'equivalent member or, members adapted tohold the part1 .in lifted position and permittingto movements'ofthe twop'arts 1 and 2 relatively to one another, as in Fig. 1.

From the bottom 2 of the lower part 2 extends upwardly a bracket 13 which is rigidly connected with an eye 8. This is. the eye already mentioned in the preceding paragraphs and serving for coupling the device with the ceiling hook. The bracket 13 serves at the same time as bearing for a pin 14: supporting a cord roll 9. The cord. (which is indicated only by dotted lines) ex tends through bores 2 and 2 provided in the bottom 2 Attaching the top member 1, 2 to the ceiling hook is effected by depressing the part 1, downwardly over the part 2 so that the eye 8 can be hung into the hook screwed into the respective ceiling beam. When the hook and the eye have been coupled with one another,

the part 1 is released so that it can be lifted by V though a rigid connection atthe ceiling seems to exist. 7

The constructional form shown in Fig. 2 is distinguished f-romthat shown in Fig; i '1 merely by the other members by which the eye 8 is connected with the bottom 2 of the lower part. In this constructional form it is. assumed that theflamp is suspended by the intermediary of the current-conducting wires which extend into the top member 1, 2 through a pieceof tube 15 connected with .theflb'ottom 2 in thef'manner shown i'n'this figure, Finally, in Fig. 8 it is assumed that V the lamp is to be suspended by means of a chain 12, and that the upper end of the top member ,1, 2. isvprovided with a rosette 11 as .an'i-mprovement of the appearance of the device.-

We. claim: V

A support for suspending illuminating bodies fromceilings, comprising, in combination, two tubular members arranged tele- 'scopical'l'y' with respect to one another in vertical position; a compressive helical spring inserted between. said members and being 10- cated at the inner circumferential surface of the u per tubular member, and supporting the upper member elastically upon'the lower member, thus permitting movement of the upper member down 'upon and over the lower member; and means for connecting the lower member with a ceiling hook, substantially as set forth. In testimony whereof we afiix our signatures. I p
