The present invention relates to wall boards and particularly to an improved fastening device, for securing wall boards in position.

Prior to going into the details of this improved fastening device, it is well to give a rsum of the extent of use of wall boards.

At first wall boards were used for erecting partitions either in rooms in dwellings or ofiice buildings or the like. A further use of wall boards is in the construction of new dwellings, wherein practically all the partitions may comprise wall board, and more especially in bungalow type houses as well as in some relatively inexpensive apartment houses or small ofiices.

Still another advance use involves the construction of corners, exteriorly and interiorly of rooms, therefore with this present inven tion there is an extensive field-for a practical and improved fastening device. I

The present invention has for its purpose to provide a very inexpensive and improved form of construction, which will permit of the expansion and contraction of the wall board sections, and yet insure a closed joint between the sections.

Heretofore in employing wall board a wooden moulding is used for covering the seam of the wall board sections, the latter being fastened to the studding, and in this construction there is no way for permitting of expansion and contraction, but there is no practical way of providing for the proper paint job. In other words the wall board with the wooden moulding is first fastened to the studding, then the moulding is applied and subsequently the wall board and moulding are painted.

Consequently as there is expansion and contraction to the wall board sections the wall board will buckle between the strips of moulding, and in the construction where moulding is used to permit of expansion and contrac tion of the wall board sections, the wall board sections will so contract as to move relatively to the moulding and expose unpainted surfaces of the wall board, presenting a very untidy and undesirable appearance.

It is therefore the purpose of the present ms. Serial m. came-1.

invention to provide an improved fastening devlce for moulding andwall board sections, such as will permit the moulding and the wall board to be painted and subsequently the moulding forced on in place. However prior to fastening the moulding home the wall board may be painted under the moulding, so that when the wall board contracts, no unpainted surface of the wall board will be exposed. In other words this invention involves the placing of the molding in one position while the wall board is being painted, in order to paint under the moulding, and forcing the moulding into a section position subsequently to completing the painting of the surface of the moulding and wall board.

Another purpose is to provide a moulding first fastened directly to the studding and not to the wall board or other wall covering, allowing the wall board to expand and contract at will.

Still another purpose is to provide moulding and fastening device combined, the keeper section of the fastening device may be carried by the studding, while a locking tongue to be received by the keeper, may be carried by the moulding proper. v

A further purpose is to provide a moulding and fastenin device for wall boards, whereby the moul mg may be held in one position by means of a snap joint and disposed in its final position by providin a second snap joint or connection, there y holding the moulding securely to the studding and yet permitting the wall board to expand and contract.

A further purpose is to provide a moulding and fastening device adapted for interior and exterior corners, or for exterior wall coverings.

A still further purpose is to provide for a moulding and fastening device which may be used for fastening wall board to the usual now'extensively used plaster walls, the wall board covering in such an instance being an imitation of tiling, making the wall board particularly adapted for painted rooms and the like.

It is to be understood that the particulars herein given are in no way limitative, and

that while still keeping within the scope of the invention, any desired modification of details and proportions may be made in the construction of the appliance according to circumstances.

The invention comprises further features and combination of parts to be hereinafter set forth, shown in the drawingsand claimed.

Fi ure 14 is a sectional View showing a meta studding of an I beam type, illustrating the construction of moulding such as that shown in Figure 8.

Referring to the drawings and more especially to Flgures 1, 2 and 3, 1 identifies a studding and 2 are wall board sections. To

secure the wall board sections to the studding a moulding of sheet metal -is used. This moulding comprises a base member 3 and a cover member 4. The base member is made of sheet metal, suflicientl pliable to be rolled or otherwise formed as sliown in Figures 1, 2 and 3, but sufiiciently stiff and yieldable as to permit the base member to function as hereinafter attributed to the construction. The base member is formed from a single piece of such sheet metal bent at 5, and the portions 6 beyond the bends are outwardly turned to form yielding flanges 7 which are opposed and therefore provide a channel 8. The marginal edges of the flanges are overturned as shown at 9. The flanges have longitudinal grooves 10 and 11. In other words the flanges are grooved at these points providing seats.

The cover member of the moulding is constructed from sheet metal bent on itself as at 12 whereby the parts beyond the bends are extended laterally in the form as shown to provide a longitudinal tongue 13. The opposed parts of the tongue are overlapped as shown at 14. This tongue has aneck 15 and a rounded head 16, and when the wall board sections 2 are arranged in position as in Figures 2 and 3 the cover member of the moulding may be disposed to overlie the wall board sections as shown and the tongue snapped into the grooved seats 10 of the channel, holding the cover member of the moulding spaced from the wall board sections 2. While the cover member of the moulding is in this position, the wall board sections may be painted or otherwise decorated, and such painting may be extended under the cover member of the moulding, the exterior of the cover member of the moulding being likewise painted, and after the paint is dried, the cover member of the moulding maybe snapped into the second groove seats 11 of the channel, as shown in Figure 3, so thatthe cover member of the moulding will retain the wall board sections in position, and in such wise as to permit the wall board sections to expand and contract without leaving exposed unpainted parts of the wall board sections.

It is, obvious that at any time should it be necessary to remove any two of the wall board sections, or any number of such sections, it is only necessary to withdraw the tongue of the cover member of the moulding from the channel, allowing the wall board sections to be removed. Such an advantage is very essential in the construction of partitions in old houses as well as new, so as to permit access to plumbing, gas piping and other installation usually carried in the interior of the partition.

Referring to Figure 4 it will be noted that the studding 1 is the same is in Figures 1 to 3, but the cover member 4' of the moulding is slightly modified in design, that is in ornagage, there being a first position as in Figure 2 and a second position as in Figure 3. Referring to igure 5 it will be noted that the channel and tongue construction is substantially the same as in Figure 4, with the exception that there are two base members and two channels for the moulding, the basemembers abuttin at 21, the two se members being secure to the studding 1, while the cover member of the moulding is relatively wider than those in Figures 1 to 4 and overlie both channels, the exposed wall 22 of the cover member of the moulding being of a slightly different ornamental design than those in Figures 1 to 4.

Referring to Fi ure 6 the construction of the base member 0 the moulding is relatively wide so that the remote edge portions'of the base member may overlie the sides of the studding 1 as shown at 23, the overlappmg parts to be secured by the nubs or projections 24. The channel 25 of the base member in Figure 6 is the same as that in Figures 2 an 3.,

Referring to Figure 8 the base member of the moulding has the flanges 7 b of the channel bent at.26,and the parts beyond the bends 26 are extended inwardly and have curved seats 27, there being only one set of'seats, so that in disposing the cover member of the moulding in its initial osition, the head 16 will engage the seats 2 and then when the cover member of'the moulding is disposed in its second position with its head 16 beyond the inwardly turned parts which have the seats, the opposite edges of the inturned parts will engage behind the head and hold the cover member of the moulding in position, that is after the wall board sections 2 have been painted under the cover member of the different formation or design. This moulding in Figure 9 is used on a plaster wall, the base member of the moulding being secured to the wall as at 28, and the wall board sections 29 in Figure 9 are supposed to be in imitation of tiling, so that the wall of a bath roofin will present the appearance of a tiled wa i O moulding, in construction, are identicalwith the construction in Figures 1 to ,3, with the exception that the cover and base members of the moulding arearranged for aninterior corner. a ,1

In Figures 12 and 13 the'construction of moulding is the same as in Fi res 10 and 11 as well as in Figures 1 to 3mclusive, but

Referring to Figures 10and .11, it will be noted that the cover and base members of the showing the cover and base members of the moulding adapted for exterior corners.

In Fi re 14 the wall boards 33- are disosed ad acent an I beam studding, there bemg bolts 34 enga ed in slots 35 and 36 of the base member 3 of the moulding, and the metal I beam 38, so as to hold the moulding base member in position. The mouldin base member 37 is formed with opposed anges 39, which are bent at 40, and the portions beyond-the bends have curved long 1tudinal seats 41 to receive the head 42 of the tongue 43 of the cover member 44 of the moulding, that is when the cover member 44 is first positioned. In other words the cover member 44 is first positioned with the head 42 in the seats 41 until the wall board sections 33 are painted under the cover member, then the'cover member is forced into place, its second position being against the wall board sections 33 with the head 42 of the tongue beyond the edges of the curved seats 41, as shown in Figure 16. In this figure the cover member of the moulding is ofslight- Ill) overlapping said sections, said molding having a longitudinal tongue to engage between the opposing yieldable sides of the channel, said yieldable sides having inwardly extending portions, provided with longitudinal cavities to receive a portion of the elongated tongue to retain the molding in its initial position, said tongue having a longitudinal bead to assume a position beyond the edges of the inwardly extended portions of the yieldable sides of the channel, thereby retainin g the molding in a second final osition.

2. In a device as set forth, the com ination with wall covering sections spaced causing an open seam to be formed, of a molding comprising a base section and a cover section to close the open seam, said molding base and cover sections having means connecting them whereby the molding cover section may be disposed in an initinl position to permit paintin of the well cover sections under the mo ding cover section, said base and molding cover sections including additional means to insure a second final position of the cover section, to clamp the cover section in position to prevent exposure of the unpainted portions oflthe wall covering sections.

In testimony whereof he aflixes his signalo ture.
