One-of the principal objects of this invention is to provide an improved sash guide which will efiectively seal an associated sash against the entrance of water, cinders, dust and air, and will also prevent water and other foreign matter, even if present in large quantities, from accumulating and back ng up the lower portion of the guide against the sealing means.

- Another important object of the invention is to provide an improved sash guide which permits easy removal of the sash, allows the sash to be moved up and down with very little efiort, and is quite attractive in appearv ance.

The sash guide of the invention, while capable of'rather general use, is of particularly great value in its application to the windows of railway cars, motor buses, airplanes, and other passenger vehicles which move at high speeds, as such windows are continually being subjected to hard horizontally driving currents of air containing water, cinders, dust and other foreign matter.

Other more specific objects and advantages of the invention will be apparent to those skilled in the art upon a full understanding of the construction, arrangement and operation of the improved sash guide.

In order that the invention may be readily understood, two slightly different structural forms of, the same are presented herein, but if, will of course be appreciated that such forms are primarily intended for the purpose 5 of illustration and that the invention is capable of embodiment in various other forms coming equally within the scope of the appended claims.

Fig. 7 is a vertical section through the 5b strIip, taken on the line 7-7 of Fig. 4; ig. 8 is a horizontal section through the taken on the line 88 of Fi 4; ig. 9 is a fragmentary outsi e face view of a single sash window embodying a slightly to modified form of the invention;

Fig. 10 is a horizontal section through one side of the window, taken on the line 1010 of'Fig. 9;

Fig. 11 is a vertical section through the bottom of the Window, taken on the line 1l11 of Fig. 9; and

Fig. 12 is an outside face view of the guide shown in Figs. 9 to 11 inclusive.

The railway car window shown in Figs. 7" 1 to 8 inclusive of the drawings is of the double sash type, but the invention is equally applicable to windows of the single sash type, which latter type is used quite extensively in motor buses and in railway cars engaged in '15 suburban service.

The particular window shown in those views consists of an outside sash 10 and an inside sash 11, which sashes are positioned in a window opening 12 and are slidably mounted in two double guides at the sides of the opening. The guides are the same at both sides of the opening, wherefore only the guide 13 at the left side need be described.

The guide 13'includes a sheet metal strip 3 14 (see Fig. 2) which is attached by screws, bolts or other suitable means, to the post plate at the side of the window opening. The portions of the guide which engage with the outer and inner sasheslO and 11 are separated from each other by a center rib 15 which is formed in the strip 14. If the guide is used for only one sash instead of two, the strip 14 may be terminated at the location of the rib 15 and only the outer portion of the strip employed.

The outer portion of the strip 14 is positioned in opposition to the edge of the side rail 16 of the outer sash, and is provided with an outer groove 17, an inner groove 18,

stri

a connecting web19 between the grooves, and a side wall 20 which projects beyond the web 19 flush with the inner side'of the inner groove '18.

' The inner groove 18 contains a thin, flexible '5 spring strip 21 which projects from the.

groove in outwardly bent converging relation 'to the inner face of the side rail 16 of the which projects from the groove is of out-- wardly convex channel formation, resulting in a groove 26 in the inner face of the strip in slightly spaced opposition to the outer face of the side rail 16. The groove 26 in the strip contains a thin, flexible spring strip 27 which converges toward the outer face of the side rail 16 and engages resiliently at 28 in line contact with the latter.

The portion 24 of the strip 23 mav be pr vided with several bayonet slots 29 for inter locking engagement with rivets, screws or other suitable members positioned crossmum of friction, and also affords wise in the groove 17, or any other suitable means of attachmentvmay be employed. To remove the sash 10, it is merely necessary to shift the strip 23 upwardly a little in the groove 17, whereupon it may be moved laterally out of the groove.

The sash 10 is thus supported resiliently between the thin, flexible spring strips 21 and 27, in line contact only with such strips, with the side wall 20 limiting the extent of inward movement of the sash and with the outer edge; of the channel-shaped portion of the strip 23 limiting the outward movement of the sash. This construction permits the sash to be moved up or down verv easilywith a minian efficient seal along the contact lines 22 and 28.

The outwardly convex channel portion 25 of the strip 23 is provided, near the lower end thereof, with several downwardly and outwardly opening louvers 30 for carrying away the water, cinders and other foreign matter which passes the edge of the strip and enters the groove 26. The louvers 30. bv affording free drainage for the water an d other foreign matter in the groove 26. prevent the same.

from accumulating and building up inside of the groove along the sealing line 28.

The water which runs down the outer face of the strip 23 from the louvers 30 is deflected outwardly away from the lower end of the strip by a curved lip 31 at the bottom of the strip. which lip is preferably coextensive in width not only withthe channel portion 25 of the strip but with the inner attaching portion 24 as well and is spaced only far enough away from: the latter to accommodate the adjacent flange 32 of the strip 14.

The water and other foreign matter is prevented from reaching the lower end of the groove 26, and also from entering the bottom of the groove from below, by a vertically elongated plug 33 of triangular cross section,

which plug substantially fills the space in the lower portion of the groove between the base of the groove and the outer surface of the spring strip 27 but is so proportioned as to not interfere with the action of the latter. The plug 33 extends upwardly a little past the bottom of the lowermost louver 30, and is beveled off at thetop to direct the descending water and other foreign matter toward the currents impinge against the spring strip 27,

the converging relation of the same with re spect to the outer face of the side rail 16 serves to make the strip hug the rail even more snugly, thereby increasing the effectiveness of the seal afforded by the strip. While this improvement has been described in its application to an outer guide portion which is deit is also applicable to an outer guide portion which is not detachable, since it is frequently found desirable to so construct the guide as to permit removal of the sash from'the inside of the bus or car.

Such an arrangement is shown in Figs. 9 to 12 inclusive. In those views, the improvement which constitutes the invention is embodied in a guide 34 of the single sash type, which guide has a fixed outer wall 35 and a removable inner wall 36. The outer wall 35 overlies a thin flexible spring strip 37 which is seated in a groove 38 in the back of the guide. The spring strip 37 is of less width than the outer wall 35 and projects from the groove 38 into line contact engagement withthei outer face of the side rail 39 of the sash at 0.

in the lower end thereof, with a plurality of downwardly and outwardly opening louvers 41, which are intended to function in the same way as the previously described louvers 30, and the outer wall is also provided, beneath the louvers, with a downwardly and out wardly extending deflecting lip 42, which is intended to function in the same way as the lip 31-. The space between the outer wall 35 and the outer face of the side rail 39, beneath the lowermost louver 41, is preferably occupied by a filler member 43 which, like the previously described block 33, serves to shunt tachable, it will of course be understood that 1 i The outer wall 35 of the'guide is provided,

the foreign matter through the louvers without interfering with the lower end of the spring sealing strip 37. The edge 44 of the outer wall is shown as substantially straight,

instead of being turned toward the outer face of the side rail, but it may of course be turned in-if desired.
