Claims.
My invention relates to a new and useful improvement in a molding adapted for use on wallboards and has for its object the provision of a molding which will be simple in structure, eco- 5 nomical 'of manufacture, durable and highly eiicient in use and easily and quickly manufactured.
Experience has shown that wallboards are subject to expansion and contraction, and since 'these wallboards are laid in sections difliculty has been encountered due to the fact that upon contraction, the joints would open, and the enamel or paint, with which the same had been finished, would be broken at the joints, so that l5 a very unsatisfactory appearance would result.
Experience has also shown that when these wallboards expand, they sometimes bulge or buckle at the joints, which also is an unsatisfactory feature. In the present invention I have provided a 'molding which eliminates this objectionable feature and provides a structure in which there can not be any open joints resulting from contraction and buckling which result from expansion. I It is another object of the present invention to provide a molding of a resilient material, so
constructed and arranged, that the portion en-l gaging the edges of the wallboard will move in response to pressure exerted thereon, thus permitting the wallboard to expand and maintain itself in close contact with the wallboard even when the same contracts, so that open joints are entirely eliminated.
Another object of the invention is the provi- 85 sion of a molding formed from resilient material and having a portion engageable with the wall- 4board formed on a curved portion to assist in the springing effect desired on the molding.
Other objects will appear hereinafter.
40 The invention consists in the combinations and arrangements of parts hereinafter described and claimed. A
'I'he invention will be best understood by a reference to the accompanying drawing which 45 forms a part of this specification and in which,
Fig. 1 is a perspective View of a fragment of a wallboard showing the invention applied.
Fig. 2 is a sectional view taken on line 2-2 of Fig. 1, with parts broken away.
5g Fig. 3 is a, sectional View taken on line 3-3 of Fig. 1. Fig. 4 is an end elevational view of one form of the invention illustrating the iiexing.
In the drawing, I have shown various forms of the invention depending upon the particular location of the molding. While the invention is .(Cl. 'l2-121) illustrated in dierent forms its function and operation remain substantially the same in al1 forms. The wallboard 1, which is commonly used, may be formed from any suitable material but is generally formed of a bre composition. 5 These wallboards 1 may also lbe made of different thicknesses but the molding will of course be constructed for use with a wallboard of predeterminal thickness. In the drawing I have i1- lustrated different types of molding. The mold- 10 ing A may be termed an intermediate molding as it is positioned between sections of wallboard, lying in the same plane. The molding B may be termed an external corner molding, the molding C an internal corner molding, the molding D 15 a terminal corner molding and the molding E a base molding. As clearly appears in Fig. l and Fig. 2 the molding A isformed from a sheet of metal having a bulged central portion to provide a U-shaped channel projecting outwardly from 20 which are flange portions 9 and I0. The side walls II and I2 of'this molding serve as abutments for the edges of the wallboards between which the molding is positioned and the blght 8 of this channel structure, which connects the 25 side walls II and I2, is curved. The wallboard is secured to the wall by means of brads driven through the flange 9 or Ill into the studding I3 or other support. When placed in position the side walls II and I2 are pressed inwardly against 30 the resiliency of the metal from which they are made and thus they are under strain and closely engage the edges of the wallboard sections.y These side walls II and I2 are not pressed inwardly to the limit of their relative approach and upon expansion of the wallboards, they may move inwardly toward each other farther. Upon the contraction of the Wallboards, these side walls will move outwardly from each other as the inward pressure is released so that an engagement in close contact is maintained between the side walls and the edges of the Wallboards at all times. Consequently there can be no open joints at the line of engagement between the wallboards and the side walls II and I2. The result is that enamel, paint or any other varnish upon the wall, will not be broken at the joints upon expansion and contraction of the wallboards. In Fig. 4, I have illustrated the flexing of the molding when mounted in position. In Fig. 4, the full line illustration indicates the molding in its normal position and the dotted lines indicate the molding when placed under strain. 'I'his clearly indicates that the members II and I2 are exed inwardly toward each other 55 and that the curved body or bight 8 is also exed when the strip is placed under strain. It is believed that in the other forms illustrated, the flexing will appear obvious from the illustration indicated in Fig. 4.
The molding B is similarly constructed except that the side walls II andv I2' are bent angularly inwardly toward each other, and the flanges 9 and I0' extend at right angles to the side walls II and I2' which are directed toward the base 8 at a diierent angle than are the flanges 9 and I2 toward the curved portion 8. The operation and function of the molding is as already described for the molding A.
The molding C embodies a curved body 8" having the side walls II and I2 extending outwardly from which are the flange 9" and I0". 'lhe function and operation of this molding is as already described but it will be noted that the curve of the body 8" is faced oppositely to the curve of the bodies 8 and 8'. The molding E is of slightly diierent structure as it is necessary that it have only one part engaging the wallboard.
This molding comprises a sheet of metal having a curved body 8"' extending from which is the rearwardly bent flange I4 which rests upon the iioor I5. Extending rearwardly from the upper end of the curved body 8', is the engagement wall IB against which the edge of the wallboard engages and an angularly turned flange I1 extends from the wall IIS and lies behind the wallboard 1. 'I'he curved body 8" serves as a means for permitting the movement of the wall I6 in response to expansion and contraction so that a tight engagement against the edge of the wallboard 'I is always maintained.
Thus I have provided a molding having a curved spring-like body, carrying at its end a flat engagement portion which engages against a wallboard edge under strain and which follows the edge of the wallboard in its movements resulting from expansion and contraction. In this way I have provided a molding which obviates the disadvantages enumerated and attains the functions mentioned. The wallboards engaging opposite sides of the spring-like body may be termed abutments and while there is some movement of these wallboards in response to expansion and contraction, they may, it is believed, be termed stationary abutments. The floor against which one side of the spring-like body is engaged in the structure shown in Fig. 3 may also be termed a stationary abutment.
While I have illustrated and described the preferred form of construction, I do not wish to limit myself to the precise details of structure shown but desire to avail myself of such variations and modiiications as may come within the scope of the appended claims.
Having just described my invention, what I claim as new, and desire to secure by Letters Patent is:
1. A molding of the class described, adapted for use with wallboards, and formed from resilient metal and comprising: a curved body portion; an angularly turned portion on said body for engaging the edge of a wallboard, said angularly turned portion being sumciently resilient for maintaining the same in engagement with said edge of said wallboard irrespective of movement of said edge in response to expansion and contraction, and a terminal ange on said angularly turned portion extending at an inclination thereto and engaging behind the wallboard with which used, and adapted for the reception of aflixing means projected through said wallboard and said flange into a suitable supporting body.
2. In combination, a wallboard; a molding formed from resilient metal and comprising a curved body; and an angularly turned portion on one side of said body engaging the edge of said wallboard and exed to a position of strain; and a stationary abutment engaging the opposite side of said body.
3. In combination, a pair of wallboards having their edges in spaced relation; a molding positioned between said wallboards and formed from resilient metal, and embodying a Lair of spaced engaging members engaging oppositely disposed edges, of said wallboards and connected to each other by an outwardly curved body spanning the space between the same, said engaging members being flexed out of normal position against the resiliency of the metal from which made.
4. In combination, a resilient metallic molding having a curved body portion and provided, on one side, with an angularly turned engaging portion and a wallboard engaging said angularly turned engaging portion, said angularly turned engaging portion being iiexed against the resiliency of the metal from which made, out of normal position while in engagement with said wallboard; an a stationary abutment engaging the opposite side of said body.
5. A construction embodying a pair of wall boards spaced apart at one of their edges; a molding positioned between the spaced edges of said wall boards and embodying a pair of spaced engaging members engaging the oppositely disposed spaced edges of said wall boards; an outwardly curved body spanning the space between said engaging members and connecting the same together and formed integral therewith, said engaging members being flexed inwardly toward each other out of normal position against the resiliency of the metal from which made, while in engagement with said wall boards, said engagement members being adapted for further movement toward each other and being maintained by the resiliency of the metal in engagement with the opposed edges of said wall boards upon further separation of said wall boards due to contraction.
