Nelson, Chicago, Ill. ' Application February 18, 1937, serial No. 126,343 2 Claims. My invention relates in general to building con struction and has more particular reference to a soundproof suspension means for the support of ceilings and other surfacing elements in a man 6 ner suppressing sound transfer through the sup ported elements; An important object is to pro vide support means for‘ceilings and similar sur facing elements in building structures while sup pressing ‘or minimizing the transfer of sound through the support. ' The utility of sound suppressing support means i will be readily perceived when it is understood ‘ 15 Figure 4 is a perspective view of a part of a mounting clip comprising my present invention. To illustrate the invention, I have shown‘ on the drawing a ceiling structure ll embodying a soundproof mounting element l3 although it will be apparent that the invention is not necessarily restricted to ceiling structures, but many aspects of the invention may conveniently be employed in soundproof structures generally and particularly in structures requiring soundproof anchorage of ill) ‘surfacing elements. In the illustrated embodiment, the ceiling that ceilings and similar surfacing elements may act as an enlarged sounding board adapted to magnify any vibration transferred thereto from the basic structure on which it is anchored, the provision of means for suppressing sound transfer between. the basic structure and the surfacing element being particularly desirable in o?ice buildings and other structures where quiet is es pecially desired and where the basic structure is subject to vibration initiating from various structure H is mounted or assembled on a basic sources. to the element l5 of the basic structure by means of the acoustical clips l3 and the cables 11 or Another important object is to provide an im 25 proved. acoustical structure particularly for use in the suspension of ceilings. , Another important object is to provide an im support structure l5, such as the concrete frame of a building in which the ceiling structure is built. This frame l5 may be formed with wires or cables I‘! embedded therein and depending there from to form means for suspending the ceiling structure II in place. The ceiling structure com prises, in the illustrated embodiment, a plurality , of beams l9 extending in preferably and sub stantially parallel spaced apart relationship and suspended at predetermined spaces with respect other suspension elements for supporting said clips. The clips l3 comprise a channel-shaped proved acoustical mounting clip for ceilings and the like, the clip being formed to substantially element 2| which may be formed of any preferred material although the element 2| may be most prevent transfer of vibration between a basic structure and a ceiling mounted on the structure by means of the clip. Another important object is to provide a mounting clip of simpli?ed and inexpensive con- ‘ by bending the opposite ends of a rectangular strip of material to form parallel, spaced-apart struction and simpli?ed means for mounting the samein position to support a surfacing element on a basic structure. Another important object resides in the pro vision of an improved method for the soundless 4 O support of ceiling and similar surfacing elements in a building structure. ' These, and numerous other important objects, advantages, and inherent functions of the inven tion will be more fully understood from the fol conveniently produced as a sheet metal stamping , wall‘ portions 23 interconnected by means of a joining wall 25 clearly shown in Figure 4. Retain’ ing clips or lugs 21 are arranged at the edges of the walls 23 as shown in Figure 4 andthe‘secli‘ps may be separate pieces welded or otherwise fas tened to the said walls or may be formed integral therewith if desired. Within the channel 21, I arrange a layer 29 of felt'or other suitable sound 40 deadening material, said layer preferably com prising a strip of material adapted to fit within and cover the inner walls of the channel. The clips 21 may be folded inwardly as shown in Figure 3 after the acoustical layer 29 is assem 45 lowing description which, taken in connection _ bled within the channel 2l in order to hold the with the accompanying drawing, discloses a pre parts in place, the edges of the clips being adapt ferred embodiment of the invention. ed to grip the edges of the acoustical layer and to Referring to the drawing: ' Figure 1 is a fragmentary perspective view of a clamp the same against the walls of the chan ceiling suspension embodying the present inven tion; , Figure 2 is a perspective view of parts of the structure illustrated in Figure 1; Figure 3 is a sectional view taken substantially 55 along the line 3—3 in Figure 2; and nel 2|. . 50 It will be noted that the clip I3 is of extremely simple and inexpensive construction, and is adapted to receive the beams l9, which may be steel channels or other preferred forms, within the channel and that when so assembled the 55 2 . 2,124,311 beams will be bedded in the resilientsound dead ening acoustical material 29. Of course, any number of mounting clips [3 may be utilized in ‘supporting a beam and the beam ‘may’ be hung in a desired spacement merely by wrapping the suspension cables I‘! each around a clip- 13 in‘ the manner illustrated in Figure 2 of the drawing. Of course, any other kind of suspension element , may be used in placeof the cables II, but a cable 10 comprising a flexible Wire will not transfer such vibration from the basic structure £5 to the ceil ing structure as a more rigid element. Conse quently, ?exible support elements are preferred. Any vibration which is transferred through the 15 suspension element I‘! to the clips I3 will be largely, if not entirely, absorbed in the layer 29 and will not be transferred to the beams I9. The beams l9, therefore, form a substantially soundless support on which the ceiling itself may 20 be erected. The ceiling, of course, may be of any preferred structural form and may comprise a plurality of spaced cross beams 3| anchored in spaced-apart relationship on the beams [9 in any suitable fashion and preferably by means of the 25 tie elements 33 comprising in the illustrated em bodiment pieces of wire wrapped around the beams I9 and 3|. The spaced beams 3!, of course, provide an anchorage for the ceiling 35 Surfacing elements, such as ceilings, when mounted in the manner heretofore described, are substantially soundproof. That is to say, any vibration originating or initiated in the basic support structure I 5 may not reach the surfacing Cl structure H, all vibration transmitted through the suspension elements I‘! being excluded from the surfacing structure by the resilient layer 29. The structure, however, has adequate strength to support the weight of the surfacing structure H 10 and if desired, a layer of sand may be spread upon the upper side of the ceiling 35 to increase its sound excluding properties. It is thought that the invention and its nu— merous attendant advantages will be understood from the foregoing description, and it is obvious that numerous changes will be made in the form, construction, and arrangement of the several parts without departing from the spirit and scope of the invention or sacri?cing its attendant ad vantages, the form herein described being a pre ferred embodiment for the purpose of illustrating the invention. What I claim is new and desire to secure by Letters Patent of the United States is: ‘ 1. In a suspended structure comprising a plu rality of spaced-apart ceiling bars, the combina tion of saddles receiving said bars at spaced in which may also be of any preferred material or V tervals, said saddles each comprising a plate bent 30 structural character. In the illustrated embodi to form a channel having spaced-apart side walls a. ment, the ceiling 35 comprises a plaster receiving and an integral connecting wall, and a piece of layer 37, such as expanded metal or other foram resilient material covering the inwardly facing inous construction, which is secured on the beams surfaces of the walls of said channel whereby to 35 in any convenient or preferred manner, for resiliently seat a bar in said saddle, and ?exible 35 example, by utilizing the ends of the wires 33 to secure the plaster retaining layer 3‘! in place. Alternately, if the beams iii are of wood or other 40 45 50 55 nail receiving material or construction, the layer 3? may be mounted by nail-like fasteners. The layer 31 also may comprise wooden slats nailed in place on the beams 3!. The ceiling may be ?nished by applying a ?nishing layer 39 on the layer 31 and this ?nishing layer 39 may be plaster or any other surfacing material depending, of course, upon the nature of the underlying sup port layer 3'! and it is entirely within the con ception of my present invention to form a ceiling of boards nailed or otherwise attached directly upon the beams 3|. While I have illustrated and described the pres ent invention as applied in ceilings, it is obvious that the sound excluding clip l3 may be utilized to advantage in anchoring other surfacing ele ments and I, therefore, do not wish, necessarily, to restrict my present invention merely to ceiling structures. suspension members anchored in and depending ' from a foundation structure and secured‘ to said saddles to suspend the same and the bars seated therein from said foundation structure. . > 2. In a suspended structure comprising a plu rality of spaced~apart ceiling bars, the combina tion of saddles receiving said bars at spaced in tervals, said saddles each comprising a plate bent to form a channel having spaced-apart side walls and an integral connecting wall, and a piece of 40 resilient material covering the inwardly facing 45 surfaces of the walls of said channel whereby to resiliently seat a bar in said saddle, and ?exible suspension members anchored in and depending from a foundation structure, said flexible mem bers comprising wires having dependent portions 50 twisted into loops about said saddles to support the same and the bars seated therein from said foundation structure.
