' 7 Claims. (Cl. 20G-50) This invention relates to an improved cloth board of the type employed as a support for a web or roll of Woven fabric to facilitate the handling and display of the same as Well as to provide for the ready' removal of a portion of the fabric.

One object of the invention is the lprovision of a` cloth board of this characterwhich is of light Weight and rigid construction, and which iscapableef being made and assembled more cheaply than the usual devices of this character now in use.

Another object ofthe invention is the provision of a device of thischaracter so constructed and o arranged as to provide a tensoned effect between the cover'4 and frame which servesto hold the cover under tension and at the saine time to retain the frame parts in a position of rigidity.

A further object ofthe invention is theprovisionA in a device of thisrcharacter of a cover means or strip of sheet material surrounding the frame and attached thereto only at pointsadjacent the frame ends, whereby that Vportionof the cover strip located intermediatethe frame ends is maintained free from wrinklesor folds to form a `uniformly even surface `of the board.

Another object of the invention istheoprovision in a structure of this character ofv a frame comprising side rails of a resilient character having outwardly flaring edgey portions adapted for engagement with the cover strip to impart reciprocal tension to ther strip and frame.k

Another object of the invention is the provi` sion of novel connecting means between the side rails and spacing members, whereby the side rails are capable of slight movement towards and from each other to permit the rails to be drawn closely against the spacing members by the tension exerted thereon by the cover strip to increase the rigidity ofthe frame.-

Other objects and advantages of the invention relate to various improved details of construc tion and arrangements of the parts as will be more fully set forth in the detailed .description to follow. T.

Referring to the drawingz- Y Fig. 1 is a perspective view of the improved cloth board, a portion of the cover strip being broken away to indicate more clearly the manner y trating the cross sectional shape of the opposed side rails,

Fig. 4 is a transverse sectional view, taken substantially alongthe line 4 4 of Fig. 2,

Fig. 5 is a detail sectional view showing the means connecting one of the side rails with one of the end spacing members, taken substantially along the line 5-5 of Fig. 2, and Y Fig. 6 is a detail sectional view through one of thev end spacing members, taken substantially along the line Ii-v-( of Fig. k2.

In that form of the invention illustrated kherein the frame I comprises a pair of opposed side rails 2, which are preferably formed. from thin metal or other suitable material such Vas is capa]- bleof being readily shaped to the desired form and which possesses a fair degree of resiliency.

EachA of the siderails is shaped to provide a transversely curved portion 3 terminating inoutwardly flaring edge portions 4 extending substantially throughout theV entire length of each side rail. The aring edge portions ,4 may be so formed as to lie in planes substantially tangential to the curve of the rounded or curved portion 3 of each side rail and extend initiallythroughout substantially the entire Ylength of the rail and upon opposite sides of theplane of the frame. A plurality of spacing members may be interposed between the opposed side rails, which in the present instance comprise oppositely positioned end members 5 and an intermediate spacing member 6. The opposed end members 5 are of similar construction and each may be provided with opposite side walls ,'I spaced from each other a distance substantially equal to the thickness of thecompleted cloth board, and a wall 8, which serves to form one end wall of the completed cloth board. The end spacing members 5 are also provided with rounded end portions 9 shaped to t within and conform substantially With the curved portions 3v of the side rails.

The intermediate spacing member is similarlyprovided with opposite side walls I I adapted the side Walls 'I of the ,end members when the parts are assembled, a Wall I2 Vconnecting the opposed side walls I I, and rounded end portions I4 adapted to t within and conform substantially with the curved portion 3 of the opposed side rails.

The end spacing members 5 niay each be provided with a shallow recess or depression I6 formed in the outer face of the end wall 8, which may be shapedV to provide substantially straight lateral shoulders I 'I in such a manner that a Y to be located substantially Within the planes of designating strip of paper or the like I8 may be inserted within the depression in such a manner that the opposite side edges of the strip I8 will frictionally engage the straight shoulders I1 whereby the strip I8 may be substantially retained within the depression I6 through engagement of its side edges with the lateral shoulders I1.

In practice it is regarded as preferable that the opposed side rails be secured to the end spacing members 5 only by some form of securing means which will permit if desired a slight degree of play between the aring portions 4 of the side rails and the adjacent surfaces of the end spacing members, and as illustrating one form of such attaching means which may be advantageously employed there is shown in Figs. 3 to 6 inclusive, cooperating lugs 2! and 2l formed by being struck out from the metal of the side rails and end spacing members and arranged in substantially interfitting relation with each other, the planes of the lugs 2S and 2l being located at substantially right angles to the longitudinal extent of each side rail. In the present instance a plurality of interiitting lugs 20 and 2| are provided between each side or flaring portion of each rail and the adjacent portion of each end spacing member, although the number of interfitting lugs provided may be increased or decreased as found desirable or in order to permit greater or less freedom of movement between the flaring edge portions 4 of the side rails and the adjacent portions of the opposed end spacing members.

In the present instance the spacing members 5 and 6, like the opposed side rails 2, are shown as being formed from thin metal, and are drawn or otherwise shaped to give them the desired form approximating the cross sectional shape of the completed cloth board.V It will be understood however that the spacing members 5 and 6 may beformed from various other materials possessing the necessary rigidity and adapted to serve as supports for the side rails.

In making the frame I the several parts may be assembled in substantially the form shown in Fig. 2 of the drawing, and the lugs 2l) and 2I of the desired number and arrangement formed by subjecting the assembled parts to the operation of suitable automatic punches for striking out the interiitting lugs.

Upon completion of the frame I a sheet 22 of paper or other suitable fabric material is placed therearound in a direction transversely of the frame and has its free ends pasted or otherwise secured together to form a substantially continuous cover strip surrounding the frame and serving as a cover for the frame. In applying the cover strip 2 it is desirable that the strip be xedly secured to the frame only at points adjacent to the frame ends, and for this reason the frame ends extending outwardly from the lines 24 are preferably treated with a suitable composition of material such as a bronze or aluminum lacquer or paint, or a varnish, or a combined lacquer and varnish to cause the paste or glue placed upon one side of the strip 22 to adhere to the external surfaces of those portions of the frame located outwardly of the lines 24 as indicated in Fig. 2 of the drawing. In order that there may be no adhesion of the cover strip' to those portions of the frame located intermediate of the lines 24, those portions of the frame structure lying between the lines 24 may be oil treated or otherwise prepared to render the paste or glue carried by the cover strip ineffective to cause adhesion between the cover strip and the intermediate portions of the frame. 'Ihe adhering portion of the cover strip is indicated more particularly by the reference character 25 as shown in Fig. l, while the non-adhering portion is indicated by the reference character 26 in that gure.

The cover strip may be coated upon one side thereof with a suitable adhesive throughout its entire area and is preferably moistened before its application to the frame. The freeend portions of the cover strip are secured together by the adhesive as previously described. As the cover strip is applied it is drawn fairly closely about the opposed side rails, and as the cover strip dries, it contracts slightly, and draws against the flaring edge portions 4 of the side rails, which, in turn, tend to press it outwardly by reason of the resiliency inherent in the side rail members, thereby tensioning the cover strip more or less uniformly throughout the major portion of its extent. This in turn reacts upon the opposed side rails to draw them towards each other. The reciprocal tensioning effect between the aring edge portions 4 of the side rails and the cover strip Y22 imparts a high degree of rigidity to the frame and gives a smooth and tensioned effect to the cover strip throughout substantially its entire area.

The resulting cloth board is'capable of being readily constructed and provides a device of this character which' is of extremely light weight, while possessing great rmnesss and rigidity;
