The modification shown in Figure 4 'isv generalhr similar to the one shown in Figure 1, diilering from it only in the construction of the parting -strip 20 and the ilanged edges of the weather strips 2I and 22. In this form of the invention thel parting strip 20 is made of sheet metal, as in the rst form, but is provided with a illling made o! wood, impregnated paper, or other suitable material. The ilanged edge of the weatherstrip'2I is bent out and back toY form a tongue 2Id oir double thickness lying against the edge of the trim stop I5 and the extreme edge 2 Ic lies in the same plane as the body o! th strip ZI and nts in under With this construction the metal 2id lying against thetrim stop I5 is of double thickness, which makes it stronger and allows roomior the accumulation of 'more' coats of paint on the exposed portion Ila of the stop .I5 facing the sash I0.

Both of the constructions shown, as well as other modications not shown, are simple and economical to produce. Each of the two pieces of weatherstrip is the same as the other one turned end for end, so both can be produced in a single set of rolls. The metal parting strip, being of box-section, is quite rigid and can be se. curely held by few screws. seen that the entire assembly is economical to produce and apply, besides providing all-metal guiding surfaces for the window sashes.

What I claim is:

l. In combination, a window frame member, a pair of wooden stops secured thereto in spaced relation, a parting stop secured to the face of said frame member between said wooden stops and dividing the space between them into two channels, said parting stop having metallic side striplto hinder the lnv From this, itcan be surfaces, weather strips in each of said channels having their edges held by said stops, said weather strips being separate from said parting stop and having 'flanges lying against the sides of said wooden `stops and shoulders fitting against the sides of the parting strip.

2. In combination, a window frame member having a flat face, a stop secured against one edge o! said frame member and projecting beyond the face thereof, `a weather strip lying on the face of said frame member with a portion fitting into a slot in said stop, said weather strip having a ange lyingjagainst the side of said stop and a shoulder spaced and facing away from said lstop, a parting stop lying against said shoulder and securedto the faceof1 said frame member, a

Asecondweather strip having a shoulder tting against the opposite side -of said parting stop from said first shoulder, said second weather strip alsohaving an upstanding flange spaced from ysaid shoulder and a portion projecting beyond said ilange, and a third stop secured to said frame member and fitting over said projecting portion and against said flange.

3. In combination, a window frame member having fia't sides, a pair of stops each secured directly o n a iiat side o! said frame member and forming therewith a channel for the edge of a window sash, one of said stops having a metallic surface and the other a wooden lateral surface facing said metallic surface, and a metal weather strip lying in said channel, said weather strip having portions extending outwardly of said channel and covered by said stops and having-a flange covering a part of said wooden lateral surface.

4. A sash guide comprising parallel strips Aof metal each having a flattened inner edge, a reversely bent portion adapted to extend in grooves formed in afwindow sash and a channel wall comprising a reversely bent outer edge residing outwardly of said sash, and a sash parting stop comprising a separate hollow metal strip jointly overlying said inner edges; and means passing between said edges for securing said parting stop vdirectly to a window frame thereby snaring said inner edges between said stop and a window frame.
