2 4 Brief Summary of the_Inventlon Briefly, the present invention comprises improvements to carrying bars for suspending ceiling with the improvement come prosing a plurality of spaced ears which permit the dry wall furring channel to be directly attached to ye carrying bar without the use of fasteners such as wires, screws or the like.

Description of the Preread E~d~ment Referring to the drawings and, more particularly, to Fig. 1 and Fig. 2, reference numeral 10 generally designates a front view of the U shaped channel member or carrying bar of my invention. Carrying bar 10 has a web 16, an upper flange 15 and a lower flange 14 what form a generally shaped member to thereby provide rigidity to carrying bar 10. Typically, carrying bar 10 are made of metal or the like and are in lengths of six fee or

longer. Located in web 16 of carrying bar 10 are a plurality of holes 13 which I space at predetermined distances L along the length of carrying bar 10. Typically, hole 13 art spaced four inches apart; however, for convenience other spacing could be used. Holes 13 are for use in attaching carrying bar 10 to the room ceiling with wire or the like. That is, one end of wire is attached to the ceiling and the other end of the wire is fed through hole 13 and then wrapped around the top portion of carrying bar 10 to form a wire suspension support for carrying bar 10.
Located on the underside or in lower flange 14 of carrying bar 10 are a plurality of punched ears 19 and 20. Ears 19 and 20 face toward each other and have a predetermined spacing A from the center point of one set of ears to the center point of an adjacent set of ears. Typically, spacing A it six inches since such spacing permits mounting of dry wall furring channels on 12, 18 or 24 inch centers. The gap between the underside of flange 14 and the inside surface ox ears 19 and 20 is slightly larger than the thickness of the flanges on the dry wall furring channel to provide a slight clearance for insertion ox the flange of the dry wall furring channel therein. In addition, the longitudinal spacing between the back portion of ears 19 and 20 is such that to transversely mount a dry wall furring channel without sliding the channel into the ears one must squeeze or compress the dry wall furring channel before it can be transversely fastened in ears 19 and 20.
Also, if desired, the Racing A may be eight inches to permit mounting of dry wall channel on 16 ox 24 inch centers.

Reference to Fig. 3 shows a ceiling support system gun orally comprising a plurality of carrying bars 10 and a plurality of orthogonally located dry wall furring channels 11 which are attached to carrying bar 10 through ears located on thy underside of carrying bar 10, Holding sheet jock 12 to the underside of dry wall furring channels 11 are a plurality of screws I A
sex of wires 17 attached to eyes 21 in the ceiling (not shown) and to the carrying bars 10 support the framework.
Referring to Figs. 4, 5 and 6 it will be shown how the metal resilient dry wall furring channels 11, which are commercially available can be mounted to carrying bar 10 of my invention.
Fig. 4 shows the first step in the process of mounting a dry wall furring channel 11 to my carrying bar 10. Dry wall furring channel 11 comprises a lower face 30 for abutting against the sheet rock, a set of opposite webs 31 and 32 which extend at an obtuse angle from face 30 and a pair of flat flanges 33 and 34 which extend outward in opposite directions and are used for engagement with ears 19 and 20 of carrying bar 10. Fig. 4 illustrates the first step in transversely mounting or snapping dry wall furring channel 11 into ears 19 and 20, it one first places flat flange 33 between ear 19 and the underside of flange I This brings the opposite flat flange 34 against the bottom ox ear 20.
In the next step (Fig. 5) one squeezes dry wall furring channel 11 until the end of flat flange 34 has been sufficiently displaced toward ear 19 80 that end of Lowe flange 34 clears the end of ear 20. While compressed, 'a slight counterclockwise twist of flat flange 34 moves flange 34 upward between ear 20 and lower flange 14.
Fig. 6 illustrates channel 11 after release of the compressive force which permits the dry wall furring channel to I
. ' , ~3~7~
expand to its normal dimension and permit flat flange 34 to engage ear 20, i.e., the inherent resiliency of dry wall furring channel 11 permits dry wall furring channel 11 to return to its normal post-Zion to firmly engage ears 19 and 20. This process is rep axed whenever the furring channels 11 are to be transversely attached to a carrying bar.
For purposes of clarity the spacing between ear 19 and flange 14 is somewhat exaggerated in the drawings. In practice there is usually only sufficient clearance so the top of flanges 33 and 34 abut against the back portions of ears 19 and 20 to thereby provide a frictional support against sliding of dry wall furring channels with respect to the carrying bar.
It has been found that not only does my carrying bar pro-vise for quick attachment to dry wall furring channels 11 but it also provides a more stable connection between carrying bar 10 and dry wall furring channel 11 than with wires or screws since the width of ears 19 and 20 prevent undue twisting that may occur with wire or screw attachment. In addition, I have wound that a pro determined center spacing between ears of six inches provides for locating the dry wall purring channels on 12, I or 24 inch centers.
Ego. 7 shows an enlarged view of the underside of flange 14 of carrying bar 10. In the embodiment shown ears 19 and 20 have been punched out of the flange 14 leaving holes 28 and 29, respectively, in flange 14.
While I have described the transverse attachment of dry wall furring channel to carrying bar, one may also longitudinally slide dry wall furring channels between ears 19 and 20 and lower flange 14.
Typically, carrying bars 10 are spaced from each other a distance that ranges from three to four feet One of the ad van-wages of thy use of holes 13 it what it it faster to hang tarrying bar since it eliminates the us of a wire saddle tie attachment to the bar. In addition, holes 13 at end of carrying bar 10 could be used as pilot holes for splicing carrying bars in ax end-to-end splice .
