The upper sash movements are controlled in a similar Ina-nner by pressing heads 38 and 39 and their stems inwardlykagainst the action of springs 40 and 41, so that hook 34 is disengaged from rack teeth 20, and the sash may now be lowered to any desired extent, and be held in any of its ladjusted positions by re-enfa rrement of hook 34 with the rack teeth 20 under the action of springs 40, 41, after release of the pressure on heads38, 39. j

It will be understood that have described and shown some of the possible practical con- ,structions of my metal window frame and that I may make changes therein such as are ,warranted by the appended claim without departure from my invention.

Having thus described my invention what I claim as new, and desire to seeureby Letters Patent is:

In a metal window, sash guides and sashes guided therein, rack teeth formed on part of said guides, chambers formed in the sashes,

an angular bracketin one of said chambers, the chamber for the lower sash, the horizontal arm' of said bracket attached to the bottom ofsaid chamber the end of the vertical arm vof said bracket formed into a hook engaging between the teeth of said guides, and a curvedvleaf spring attached at one end to the inner wall of said chamber oppositely disposed to said hook, its-lower free .end bearing against the hook arm of said bracket for pressing the same into engagement with said rack teeth, and a headed stud' extending Vfrom `said hook to the outside for allowing a repressing of the saine into the-chamber to disengage it from'the rack teeth,a front plate Y 'for the other yof said chambers in the upper sash having an opening therein, aplate bearing kagainstA said frontfplate', a hook'formed withsaid'plate extending through the opening of said front plate into engagement with the rack teeth, stu'ds'extending from the ends of said hook plate towards Athe outside'and carrying headspand springs wound at -one end about the inner ends of said' studs, and pins projecting into said chamber about which theother ends of Vsaid springs are wound'to normally press said' hook into engagement with said rack.

` l In Witness whereof I have signed my'narne to this specification. Y y if Y* RICHARD SALOMON.v
