This invention relates to improvements in covering for walls, and more particularly to such a covering which constitutes an assembly of sheet-metal panels, with their face portions enameled.
The invention resides in providing such a coverin which comprises an assembly of refera 1y rectangular sheet metal panels aving correlatively shaped edges to form an interlocking connection and a chamber extending between the panels. Said chamber compnsing a channel-way of one panel, through which the panel is screwed to the wall, and an extended portion of an adjacent panel which is so formed correlatively with said channel-way that a pliable sealing material, such as putty, placed in an excessive amount in the channel-way before assembly is pressed by said extended portion into the chamber formed during assembly. This construction insures a erfect seal between the panels and also e ectively seals the screw connection in the chamber and between the chamber and the wall. The sealing material thus completely filling the chamber, is greatly prevented from crumbling and falling out uring vibrations of the wall. Further, an objeclts'isto expedite the assembling of the pane Other objects and advantages will become apparent by reference to the s ecification and the accompanying drawings, in which;-

Although means are illustrated for eifecting various connections for the panels at corners of the walls, ceiling and floor of a room, the
construction of the panels and their assembly in roviding the wall covering will be descri d first, as this constitutes the main em bodiment of the invention.
Each panel 2 is provided with means for interlocking with adjacent anels and being secured to the wall 3. Said means includes a channel-way 4 formed at two adjacent edges of'a panel, and comprises a straight bottom portion 5, a right-angle, inner sidewall portion 6 connecting with the body of the panel, and an outer wall portion 7 slanting outwardly. The opposite adjacent edges of each panel have an extended portion or a flange continuation 8 folded a short way along and against the back thereof, and terminating in a hook flange extension 9; the
. flange continuation 8 covers the channel-way 4 of the adjacent panel, while the hook flan e extension 9 engages the outer wall 7 of said channel for interlocking the panels. The bottom'portion 5 ofthe channels 4 of each panel has an a erture 10, through which the panel is secure to the wall by the screw 11.
The channel-ways and'fiange continuations of adjacent panels form a substantially closed chamber 12 which extends along two adjacent edges of each panel. The inner wall portions 6 of the channel-ways 4 of the anel mentioned provide end walls for the 0 amber 12, as indicated at 13. The chamber 12 is provided for accommodating various shaped heads which may be provi ed on the screws 11, and also for holding sealing material 14, such as putty or the like. A slight 7 space 15 exists between the panels, through which the sealing material may protrude, and
which prevents the ledges of the faces of the panels from bumping to ther during any vibration of the wall 3 w ich would tend to crack the enamel on the anels.
Placed within the cavity 16 back of the panels, formed within the confines of the adjacent inner walls 6 and the adjacent hook flange extensions 9 thereof, is soundproofing materialQ17, such as ground cork mixed wit a plastic base, or the like.
The outwardly slanting wall 9 of the channel-way l of a panel secured to the wall (see Fi 5) provides a cammin action when engage by the hook flange 9 of a panel that is being forced edgewise toward said panel during assembly therewith, for forcing out excess sealing material 14 previously placed within the channel-way 4 and bringing the panels into surface alignment. However, the cavity 16 of a panel is filled with soundproofing material 17 before it is assembled to the wall.
In general, the panels 2 are assembled from left to right (referring to Fig. 2) in horizontal rows on the wall 3, or from bottom to top in vertical rows, but it will be understood that this process could be reversed, namely, assembling from right to left or from top to bottom, by reversing the interlocln'ng means of the panels.
The various connections for the panels at corners of floor, ceiling and walls will now be described.
An ornamental base 18 has been provided for the wall covering at the floor (referring to Figs. 1 and 2), which comprises abutting, enameled, sheet-metal sections 19. similarly connected with the bottom row of panels 2, and to the wall 3, as the connection between the anels and their connection to the wall; the ormations of the base sections 19 effecting said similar connections being designated by prime exponents of the numerals indicating formations of the panels 2, namely, a channel-way 4 comprising a bottom portion 5', a right-angle inner wall 6, and an outwardly slanted, outer wall portion 7, and secured to the wall by the screws 11. The bottom edges of the base sections 19 have a hook flange formation 20 which enga es a hooked strip 21 secured to the wall for olding the base sections 19 in position at the floor line. The bottom end of the vertical channel-way 4 of the bottom row of panels 2 is cut oil at 4: to accommodate the long channel-way 4' of the base sections 19.
The connection for the panels at the corner of the ceiling and the wall (referring to Figs. 1 and 2) comprises a horizontally positioned channel strip 22 secured to the wall slightly below the ceiling 3 for receiving the cut-0E ends of the panels 2 on the ceiling, similar to the panels on the wall. A sheetmetal moulding strip 23 is provided for covering the cut-off ends of the top row of panels 2 on the wall, and is held in position by the two rearwardly extending flanges 24 snugly fitting over the bottom wall of the horizontal channel strip 22. The top flange 24 of the moulding 23 serves to wedge the ends of the panels on the ceiling within the channel-way of the strip 22.
The connection provided for panels at wall corners (referring to Fig. 3) comprises a vertically positioned channel strip 25 formed similarly to the channel-way l of a panel 2, and includes a bottom wall 26 through which it is secured to the wall 3, a right-angle side wall 27 and an outwardly slanted side wall 28. The edges of the vertical row of panels at the corner of one wall are secured to the strip 25 by their hook flange extensions 9 engaging the side wall 28 of the strip. A small space exists between the side wall 27 and the edge of said panel to permit the edge of the panel 2 on the adjacent wall to enter the channel 25. The channel-way of the strip 25, being covered by the edge of a panel 2 interlocked therewith, forms a chamber for holding sealing material similar to the chamber 12 created between the panels.
WhileI have illustrated and described but one form of my invention, many alterations or omissions may be made without departing from the spirit of the invention, as dehned in the following claims:
1. A covering for walls comprising an assembly of rectangular sheet metal panels, each panel having two adjacent edges shaped into a channel-way extending therealong including a straight or flat bottom wall portion with an aperture through which the panel is screwed to the wall and an outer side wall slanting upwardly and outwardly, the
edges of the panels opposite said ad acent edges being shaped with a flange portion extending over the channel-way of an adjacent panel so as to form a chamber therewith, a pliable sealing material filling said chamber, and each panel having ahook flange formation set back from said opposite edges and extending rearwardly into hooking engagement with the outer side wall of the adjacent panel and so formed that when drawing the panels together in an edgewise manner in assembling them said hook flange and the outer wall cooperate in camming the flange portion down over the channel-way so that the sealing material placed in the channel-way is pressed into the chamber in filling same.
2. A covering for walls comprising an assembly of rectangular sheet metal panels, each panel having two adjacent edges shaped into a channel-way extending therealong including a straight or flat bottom wall portion with an aperture through which the panel is screwed to the wall and an outer side wall slanting upwardly and outwardly, the edges of the panels opposite said adjacent edges being shaped with a flange continuation folded against the back of the panel and extending over the channel-way of an adjacent panel so as to form a chamber therewith, a pliable sealing material filling said chamber, and said flange continuation terminating in a flange forming a hookfor l1ooking engagement over the outer side wall of the said channel-way whereby to cooperate therewith in camming the flange,continuation down over the channel-way when drawamaze Feb., 1931.
