One of the important features of my invention is that the clip may easily be set to the ceiling line merely by screwing it to the desired position on the extension rod and then the projecting part of the rod is sheared off.

nut II. In the suspension of furring bars by the improved suspension means of Fig. 1, the suspension rods are hooked in the holes of the concrete hanger inserts, the level line for the ceiling is run, and the clip is threaded to the desired position on the extension rod by running the rod in the nut I8. The channel furring bar is then placed in the position, as shown in Figs. 1 and 2, with the tab I I as shown in `broken lines. After the channel bar is mounted in its permanent position, the tab I4 is struck with a hammer to bend it to the locked position shown in full lines and the lower projecting end of the extension bar is sheared off.

Fig. 3 illustrates an embodiment of the inventin in which the clip 20 mounted on .the rod -2 is shown in its position securely attached to the angle bar 2l. A clip of the type illustrated in Figs. 1, 4, or may be used for attachment to the angle bar.

Fig. 4 illustrates a modiiication of the form of clip illustrated gin Fig. l1. The y clip hasjpsimilar lateral extensions, tabs and holes vfor receiving the extension yrod :2. In this modication, the nut 24 in Which the rod 2 is threaded is held in a secured position on the lower lateral extension by Welding. It is understood, of course, that an appropriate hole is formed in the lateral extension but the nut is secured in position.

In the modification shown in Fig. v5, the clip 3B is also formed of bent sheet metal. The metal is folded upon itself to form the double thickness lateral extension 3l which has a threaded hole 32 into Which the rod 2 Vis threaded. This clip also has upper and lower tabs similar to tabs l2 and I4 of Fig. 1 and is shown Vin its secured position on the channel bar 33.

ln Figs. 1 4 and .5 the clips cannot become kdisplaced by unthreading due to vibration. In the modication of Fig. `4, the nut may be left loose (not Welded). Such loose nut may be Vprevented from loosening by striking the threads with a hammer or by using one of the many self 'locking nuts.

I have illustrated the use of my invention in the installation of channel and angle bars because they are widely used for the purpose but it is to be understood that my invention is applicable to other bars such as T-bars. The tab I2 illustrated as bent upwardly to form a hook over the edge I3, may also be bent inwardly in the direction of the rod 2.

This application is a continuation-impart of `my :application ASerial No, 116;898, 31ed-,September 21, 1949, now abandoned.

I claim:

The improvement in hangers for suspending ,furring ,bars which comprises in combination an extension rod having means at the upper end for connection :to a depending hanger insert and a threaded lower lend portion, a clip formed of a single piece of `bent vsheet metal having vertically A.dispcsedbearing.sections for contacting a vertical tion maybe inserted through y the holes and `secured tothe clip :along .One side Aof thefurring bar.
