CURTAIN FOR RAILROAD-CAR- wrnnows Application filed February 26, 1930. Serial No. 431,362.

This invention relates to bottom bars for curtains, but especially has reference to the manner of securing the lower edge of the curtain to the bottom bar, and is in the nature of an antithetical construction as compared with the structures shown and described in application, Serial Number 412,627, filed December 9, 1929, by John L. Mohun and Henry Piesch.

In the application above referred to, the edges of the sheet metal bottom bar were at the top of the latter with the curtain therebetween, and these edges were prevented from spreading by the use of clamping means applied externally to said edges, but in the present invention these edges are so formed that they are prevented from spreading by clamping or retaining means applied inside of these edges and this retaining means may be either a resilient sheet metal structure or a suitably shaped solid element.

In the accompanying drawing, v Figure 1 is a cross-sectional view showing the edges of the bottom bar gripping the curtain, the latter having a hem at the bottom with a retaining rod therein, and a sheet metal strip applied inside said edges to prevent them from spreading, and

Figure 2 is a similar View, showing the curtain secured to the bottom bar by means of a solid retaining strip.

Similar numerals of reference denote like parts in both figures of the drawing. I

It will be observed that, in both views of the drawing, the edges of the bottom bar are deformed in thesame manner, and that the general contours of the retaining means are substantially identical, but this is not essential. since it will be obvious, from the description which follows, that, so long as these deformations of the edges are such that they aiford gripping surfaces that may be embraced by the retaining means, the purpose of the invention will be served, and therefore any further illustrations in these respects would be superfluous and would not contribute toward a clearer understanding of the invention. I 50 Referring to Figure 1 of the drawing, 1 is the bottom bar which is preferably made of sheet metal, and Q-isthe curtain. 7 I i The edges of the bottom bar are at the top of the'latter -and pass'inwardly' in parallelism as shown at 3, then extend outwardly and upwardly, as shown :at 4 Rand then extend downwardly and toward each other as shown at 5, these extensions being in the nature of curved deformations, thereby affording what will be termed gripping surfaces 6 which are angularly disposed with respect to the portions 3; The lower edge of thejcurtain is doubled and stitched together as at 7 to form a hem, and within the latter is inserted a rod 8, and this lower edge'of the curtain with the rod thereinislocated immediately below the bent portion fl, and the parallel parts 3 embrace the doubled edge of the curtain. 1 Sis a retaining or clamping strip which, in the present instance, is made of sheet metal and is preferably resilient, and the external contour of this strip is such that it conforms closely to the contours of thedeformed edges above noted, the dimensions of'this strip be, ing such that when it is inserted-throughout the inside of these deformed edges, it will be come slightly. compressed, which will, of course, cause the surfaces of this strip to bind closely against the deformed edges, the ends so of the strip bearing against the gripping sur faces 6,.so as to force the-parallel portions .3 of the edges of the bottom bar closely against the curtain. 7 1 v But the presence of this clampingfor retaining strip will clearly afford an obstrucs tion to prevent the edgesof the bottom bar from spreading, while the retaining rod 8 will act as a shoulder to prevent the with drawal of the curtain. i r At Figure 2 the same deformation of the edges of the bottom bar is shown, but a solid retaining strip 10 is employed whose contour generally conforms to that of these deformed edges, and preferably the dimensions of this solid strip are such that when introduced within these deformed edges it will exert a gripping action against the surfaces 6.- The 7 lower edge of the curtain extends between the straight edge portions 3 and then around one 100 i i v v V 7 1,7

side of thestrip 10 throughout its length, and the curtain will therefore be confinedb'etween the surfaces of the strip 10 and the deformations of one edge of the bottom bar, 1 while at the same time the retaining strip 10 p will becl oselygripped by bothdeformed a I edges of the bottom bar andiwill, as above; 7 7 stated, causethe grippingsurfaces 6 to bindffirmly againstthe curtain. r. 7 1 Inf'jtliis construction shown at Figure 2 it Will "be" observed that the lower edge of the curtain is not doubled uponitselflasshown 'atFigure 1, but it will be clear that the cur-v f tain can be wrapped entirely around the strip; 1O and vextend between the edgeportions 3, j ust as' shfown inFigure 1, but the confining of the curtain: between the deformations of' the} retaining stripand. one of thesid'e edges of the bottom bar, is deemed to-be sufficient,

especially as'the' contactbetween the other edge portion of the, bottom bar and the-retainin-gstripis'veryclose.
