The present invention relates to a novel and construction illustrated in the accompanying suitable device for passing cables and other drawings wherein: suitable electrical current conducting means Fig. 1 shows a roof standard in section in through roofs of any suitable type. Such arwhich the conducting members are separate fr? rangements may be referred to as roof inserts, W t 1n the SeetiOIl Shown in g- 2 ing standards. In the known forms of conhe ecnductlng members are formed by castruction they consist of a roof stand pipe and bleS O cab e-like bodies. a socket seated therein and overlapping the e head of the standard consists in the end of the pipe, on which a socket there, is eX- f nner of the protecting hood a and tremely unsatisfactory as regards penetration YES SOCKet e latter is provided with of water and moisture, prevention of short holhs {Oh the l g of the Current conduccircuits and the occurrence of fires both in the tors 5 and With s s for the reception of a d i it lf d i b ildi current distributor f to which are connected The present invention eliminates these dispp y leads 6 p g r g the pen.

V closure plate t.

Instead of the pipe it, which extends through out, there is provided at the upper part a short screw threaded pipe h secured in the socket b by means of the nut 71, the two conical bodies 0 and the pressure ring w. A further reduced screw threaded sleeve 19 presses the correspondingly reduced portion of the pipe k which is preferably slit, against the covering of the cable which is secured in this manner. At the same time the conductor wires are relieved of pull. The screw connection at the lower portion of the pipe a is effected in the manner shown in Fig. 1. As however the pipe h is omitted there is again provided a screw threaded pipe /c on which is fitted the conical nut 1 the lock nut 74 and a By. tightening the nut the pressure ring it is pressed by th conical portion of the nuts rand 6 against the inner wall of the pipe (Z. The closure disc t is also adapted to take up the axial thrust of the stand pipe (Z. This is secured by an angle iron u and'a tubular bell o to the upper side of a roof beam of a roof (Z on the upper side thereof. The supporting plate 6 engages underthe edge 8 of the stand pipe 65 and at the same time is connected by a projection with a corresponding slot in the angle iron u. The inner supporting ring w prevents the standpipe d from being deformed or crushed when tightly drawing up the tubular bell 'v. For increasing the. fireproofness the free space of the pipe (Z may be fitted with a fireproof mass for example kieselguhr 2. It will be understood that modifications may be made in the details of construction without departing from the scope of the invention.

.Vhat I claim is 1'. Means for supporting electrical cables with-respect to roofs and the like including a bracket carried by a roof element, a stand pipe carried by the bracket and rising above thereof, a hood resting on and having seal connection with the upper end of the stand pipe, a conductor pipe for the electrical cables extending longitudinally of the stand pipe and into the hood, means on the upper endof the conductor pipe to seal the same, means carried by the conductor pipe to interiock the conductor pipe and hood against relative movement in one direction, means on the lower end of the conductor pipe whereby the latter may be connected to a junction box,

and means cooperating with the conductor 7 pipe and with the stand pipe to seal the lower end of the latter.

2. Means for supporting electrical cables with respect to roofs and the like including a bracket carried by a root element, a conductor pipe 'removably connected to a juncture box and extending through and above the bracket, a hood interlocked with the upper end of the conductor whereby the upper 'end of the conductor pipe may be sealed within the hood, a stand pipe pipe, means encircling the conductor pipe and supported by the bracket, the upper end of the stand pipe having seal connection with and supporting the hood, sealing means for the lower end of the stand pipe, said sealing means being carried by the conductor pipe, and means for insuring cooperation of the sealing means with the conductor pipe to seal the interior of the latter at the lower end against the elements.

In testimony whereof I afiix my signature.
