The window frame ll supports a con-' ventional sash unit (not shown) on its outer side. The curtain I0 is arranged to be raised and lowered adjacent the inner side of the sash.

The curtain in is attached to a, roller M (Fig. 2) which is mounted on conventional brackets (not shown) arranged in the ends of the header M. The bottom end [8 of the curtain in supports a transversely arranged apron assembly l9 having its ends projecting into t e oppositel dis. posed channels [6 and receiving a pair of cables 20 and 2|.

A bottom end anchor plate 28 is provided for 5 ach cable (Fi s 2 and w ch n ud s t ral- 1y extending ste m mbers 29 f mit whward movement or the curtain apron assembly I S. The stop members 29 may be conveniently formed n. the ten ehti f plate .28 by lc ins h nd of the plate and bending the lug members 29 out 3 wardly so that they extend laterally on each side of the cable and into the path of movement of the assembly I9. The plate member 28 is secured to the channel base 26 by an attaching screw 39 and a slot 3| is provided in its lower edge for receiving the end of the cable. A member 32 is secured on the end of the cable by means of which the cable is anchored in the slot 31. The base 26 of the channel member I6 is recessed at 33 to receive the plate member 28. With this construction the apron assembly I9 may be lowered until its ends engage the stop members 29.

The curtain apron assembly I 9 comprises complementary or mating inner and outer members 34 and 35, respectively, which are preferably formed from extruded aluminum sections. Apron member 34 which forms the inner portion of the assembly-includes a relatively wide plate-like web portion 36, provided on its top edge with a thickened section 31 having a cut back or curved lower inner face 38 which forms one portion of a slot or recess adjacent the top of the apron assem-- bly I9 for'receiving the end I8 of the curtain In in clamping engagement. Apron member 34 is also provided with inwardly directed, longitudinally extending, spaced rib- like formations 39, 49, 4| and 42 intermediate its top and bottom edges, for purposes which will be described.

The apron member 35 which forms the inner portion of the apron assembly I9 includes arelatively wide plate-like web portion 43, provided at its top; edge with a thickened section 44 in which there is formed a longitudinally extending curved recess 45. The lower portion of the thick ened section 44 constitutes an inward-ly extending rib-like formation 46 which engages the plate portion 36 of the apron member 34 immediately below the curved face'38 on the thickened section 31 of member 34, when apron members 34 and 35 are in assembled relation. The curved surfaces 38 and 45 cooperate to form a tubular recess extending the full length of the apron assembly which receives in clamping relation the end I8 of the curtain II]. The end I8 of the curtain I9 is folded back and secured over a wire rod 41 or other stiffening member, forming a beaded edge for clamping engagement in the recess.

The apron member 35 is provided with inward- 1y extending relatively wide rib- like formations 48 and 49. Rib 48 is spaced from rib 46 form- 7 or recess which'is adapted to receive the cables 29 and 2 I. The apron member 35 is provided with an inwardly extending bottom flange 52 which is adapted to cooperate with the bottom edge 53 of theapron member 34 to form a flat bottom edge or face on the assembly I9. The bottom flange 52 is spaced from rib 49forming a longitudinal channel-like recess which accommodates ribs 4I and 42 of the apron member 34. The ribs and 42 and a portion of the web 43 cooperate to form a longitudinal recess 54 adjacent the bottom of the apron assembly I9 which is the same cross section asthe reces,s 50 adjacent the top of the assembly.

34 extend into the recess 5I formed between the rib formations 48 and 49 ,on the apron mem- 4 55, 56 and 51, 58, respectively, which are adapted to receive clips 59. The clips 59 are formed of a relatively hard, wear-resistant metal, such as stainless steel. Each clip 59 comprises a bent over or curved end 66,'relatively straight portion 6I extending from the curved end 69, a laterally offset portion 62 which is connected to the straight portion 6I byshoulder forming portion 63 and to a' straight terminal end portion 64 by a shoulder forming portion 65. The curved end 69 of each clip 59 is provided with a groove 56 for receiving and guiding the cable. The rib formations 39 and 49 are cut away at the ends at 6! and 68, respectively, to accommodate the curved ends 69 of the clips 59. The clips 59 are positioned on the rib members 39 and 49 with shoulders 63 and -.65 in the laterally aligned slots 55, 51' and 56, 58.

V 70 Rib formations 39 and 49 on the apron member ber 35. Adjacent their-ends the ribs 39 and 4'1 The curved ends 69 of the clips 59 extend in opp'osite directions and the offset portion 62 of each clip 59 is positioned onthe outer side of the respective rib. The straight portions 6I and 64 of clips 59 are positioned on the inside of the ribs 39 and 40 and protect the ends of ribs 39 and 40 from excessive wear due to engagement with cable members 29 and 2I. The clips 59 are readily assembled with the-apron members and firm- 1y retained-in position in the channel or recess 5|.

Apron member 34 is cut away at 69 and at III, at the top and bottom, at the end of the member. Apron section 35 is cut away in a similar manner at II at the top and at I2 at the bottom; The recesses formed by the cut-outs at the top and bottom of the end of the apron assembly I9 whenthe members 34 and 35 are in assembled relation are adapted toreceive anti-rattle members' I3 which are preferably formed of molded rubber. Each anti-rattle member I3 comprises a relatively fiat head portion I4 and a stem por tion 15 which extends rearwardly therefrom. The

anti-rattle members '13 are secured on the apronby inserting the stem portions 15 in the ends of the recesses 59 and 54 formed adjacent the top and bottom of the apron. The head portions I4 of the anti-rattle member I3 extend beyond the outer lateral faces of the apron assembly I9 and prevent metal to metal engagement of members 3'4 and 35 with-the'side guide channels I6. The head portions 14 are sufiiciently thick to extend beyond the ends of the apron assembly I9 approximately on a line with the ends of the clip members 59 so that they separate the ends of the apron assembly I 9 from the base 26 ofthe channel I6, allowing only suflicient room for the movement of the cables 29 and 2 I. In this manspaced along the "length thereof Whichextend through holes provided in the Web portion 36' of member 34 and engage in threaded engagement in mating holes provided in rib formatiOns IB and 49 of member ,35. y While the invention has been disclosed as particularly. adapted for use in railway passenger cars or buses, it will be understood that its application is not limited to such installations. It maybe employed Wherever a retractable-curtain or shade is used to cover an opening and it is desired to be able to readily raise and'lower the.- bottom of the curtain .or .shade.
