VENZIE, OE EHILADELPHIA, PENNSYLVANIA PLAETEE-BOABD STRUCTURE AND CLIP THEREFOR Application filed March 22, 1930. Serial No. 488,038.

This invention, generally stated, relates to a building construction in which conventional plaster boards are usually nailed to wooden rafters or wooden studding and later covered with a coat of plaster. These plaster boards are formed of a plaster body enveloped by a covering of thin paper. In time, as the studding or rafters sag, warp or shift, the heads of the nails employed for holding the plaster boards to place frequently tear the paper loose from the body of the plaster boards and cause openings and bulging parts to appear which tend to disfigure or mar the appearance of the finished plastering as applied to the plaster boards. Further, it takes considerable time to nail the plaster boards to place upon the wooden rafters or studding and this not only has to be very carefully done but is an expensive mode of ap lication.

It 1s the leading object of the present invention to overcome this disadvantageous feature and provide a construction of parts whereby the plaster boards are not nailed to the wooden rafter or studding, but on the contrary are secured thereto by means of a specially designed clip, so that in the event of the rafters or studding sagging, warping, or otherwise becoming out of alignment, the clips shift with the rafters or studdingand thereby move the plaster boards in a corresponding manner so that the surfaces of the plaster boards are not torn or mutilated as would be the case if the plaster boards were nailed to the rafters or studding.

A further object of the present invention is to provide an arrangement of parts where by the plaster boards may be more quickly and cheaply attached with respect to wooden rafters or studding and may be applied by unskilled labor.

A further object of the present invention is to provide a specially designed clip whereby the advantages herein-before recited may be edected.

A still further object of the present invention. is to rovide a specially designed metallic clip or appiying conventional plaster boards to wooden rafters or wooden studding which clip may be stamped from a sheet metal blank at comparatively little cost.

A still further object of the present invention is to provide a specially designed clip of metal, stamped from a single blank, provided with an apertured portion to accept nails for securing the cli to wooden rafters or studding, and in addition provided with an inturned tongue or prong for additional securing of the clip to a wooden rafter or studding.

Other and further objects of the present invention reside in the provision of the general arrangement, construction, and combina:

tion of parts, and in the provision of the spee5 drawings forming part hereof, and in which:

Fig. 1, is a view partly in elevation and partly in section, illustrating a ceiling and wall structure embodying the invention;

Fig. 2, is a fragmentary view in elevation of plaster boards attached to a studding;

Fig. 3, is a view in elevation of one of the clips shown in the foregoing figures; and

Fig. 4 is a view in perspective of one of the clips shown in the foregoing figures.

For the purpose of illustrating my inven- 55 tion I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood 90 that the various instrumentalities of which. my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangement and organization of the instrumentalities as here- 1 in shown and described.

Referring to the drawings in detail, the reference numeral 1 designates the wooden rafters of a building structure and 2 desig' nates the wooden studding of a building an structure. The reference numeral 3 designates a flooring of any desired type. According to the present invention, the plaster boards, which are-of conventional form and consist of a plaster-like body 4, enveloped in a thin paper covering 5, are attached to the wooden rafters 1 and wooden studding 2 by means of the specially designed clip, best seen in Figs. 3 and 4, so that it is unnecessary to nail the plaster boards to the wooden rafters or wooden studding. A description will now be given of one of these specially designed clips, reference being had more especially to Figs. 3 and 4- of the drawing. Each clip, which is metallic, is stamped of a single blank to provide an integral structure, and each c'lip comprises a body comprising a supporting ledge 6 extended from which is a central member 7 having a curved edge 8. Upon opposite sides of the central member 7, and extended from the ledge 6 are other members 9, each of which has a curved portion 10. Thus, each ledge 6 is provided with three extended members for contacting with a plaster board the curved parts 8 and 10 of these members being present to prevent fracture of the thin paper coverin 5. Each ledge 6 also has extended there rom an attaching member 11 apertured as at 12 and provided with a prong 13. The attaching member 11 is arranged'at right angles with respect to the ledge 6 and the apertures 12 are present to receive the nails 14 when the clip is secured to a rafter or studding. The prong 13 of the attaching member 11 afi'ords additional attachment when the member 11 is arranged in proper position with respect to a rafter or studding.

In practice the attaching member or plate 11 is placed flatwise against a rafter or studdin and nailed to place by the nails 14, the

mec anic at the same time driving home the prong 13. This position of parts is clearly I illustrated in Figs. 1 and 2. With the plate 11 secured to place the members 7 are in position to receive the plaster boards which'are fitted so that the fingers 7 and 9 abut against the outer faces of the plaster boards and form a yielding connection with the ends 'of the plaster boards abutting against the opposed surfaces of the ledge 6, as clearly illustrated in Fig. 1. In practice one of the clips is first positioned upon the floor 15 by bending over the fingers 9 as shown in Fig. 1 so that the ledge 6 rests upon the floor 15 and the clip secured to the studding 2 as previously described. A plaster board is then paused to rest upon the ledge 6 with the finger 7 abutting against the outer face of the plaster board. This position of parts is shown at the lower right hand side of Fig. 1. The plaster boards are then built up upon the studding 2 in the manner shown in Fig. 1, so that no nails penetrate the plaster boards for securing the same to the studding. At

and described in m co-pendin-g application for Letters Patent erial No. 326,453.

From the above described arrangement and construction of parts it is apparent that with the plates 11 rigidly secured to studding or rafters, thefingers 7 and 9, to ether with the ledge 6, provide means where y the plaster boards may be expeditiously fitted to place by inexperienced mechanics. It is also apparent that with plaster boards so fitted to place, any sagging or warping of either the wooden rafters or studding may shift the clips without injury to the plaster boards, as would be the case if the plaster boards were nailed directly to the rafters or studding. Thus, with the plaster boards positioned as herein described, a coat of plastering 19 may be applied to the plaster boards, as usual, and when so applied remains intact even though the wooden rafters or studding sag or warp or otherwise become out of alignment.

What I claim is: Y

1. In a building structure, a support of wood as a joist or studding, a plurality of plaster boards attached thereto end to end, and a clip stamped from a single piece of metal having a plate nailed to said support in a fiatwise manner, said plate being provided with a ledge having oppositely disposed fingers arranged to receive and retain the ends of said plaster boards without the necessity of nailing said plaster boards to said support.

2. In a building structure, a support of wood as a joist orstudding, a plurality of plaster boards attached thereto end to end, and a cli stamped from a sin 1e piece of metal having a plate nailed to sai support in a flatwise manner, said plate being provided with a ledge having oppositely disposed fingers havin curved terminals arranged to receive an retain the ends of said plaster boards without the necessity of nailing said plaster boards to said support.

3. A clip of the character stated compris- .ing a flat supporting ledge having struck out therefrom a supporting plate arranged at right angles to said ledge and apertured for the passage of nails for attachment of the clip to a wooden support, and oppositely disposed fingers to receive and retain the ends of plaster boards with respect to said ledge.

4. A clip of the character stated comprising a flat supporting ledge having struck out therefrom a supportlng plate arranged at right angles to said ledge and apertured for the passa e of nails for attachment of the clip to 9. W00 on support, a prong extended from said supporting plate adjacent said apertures for penetrating a wooden support, and oppositely disposed fingers to receive and retain the ends of plaster boards with respect to said ledge.
