Claims: The invention having been thus described, what is claimed as new and desired to secure by Letters Patent is:

1. Window hardware, comprising

a. a housing consisting of two interconnected of two interconnected parts forming a guide channel, one of the said parts of the housing having a generally U-shaped cross-section and the other part of the housing having an L-shaped cross-section,

b. a track on which the housing is fastened,

c. a pinion supported in the housing, and

d. a drive rod slidably carried in the guide channel of the housing for driving engagement with the pinion, the two said parts of the housing being of different cross-sectional heights and being also mountable together, so that first legs are positioned parallel to and adjacent to the track to form a guide channel for the drive rod, while secondary legs are positioned at right angles to the plane of the track and parallel to each other to act as supports for the pinion which is located in both parts of the housing.

2. Window hardware as recited in claim 1,

characterized by the fact that the U-shaped part has a short leg directed at a right angle to the plane of the track and contains several cutouts which are open to the outside and the L-shaped part is equipped with cut back lugs on the leg that is positioned parallel to the plane of the track and in the plane of its extension which interlock with the recesses on the leg of the U-shaped housing part.

3. Window hardware as recited in claim 2,

characterized by the fact that the long leg of the U-shaped housing part is directed at a right angle to the plane of the track is equipped with apertures which are located in the plane of the end of the short leg and which receives lugs having the same cross-section located on the free end of the leg of the L-shaped housing part and directed parallel to the track.

4. Window hardware as recited in claim 3,

characterized by the fact that the L-shaped housing part is formed of sheet-metal and is welded to the track.

5. Window hardware as recited in claim 4,

characterized by the fact that the two housing parts are connected by the engagement of the lugs with the openings to form the guide for the drive rod and are also connected by spacing members in the form of threaded sleeves positioned parallel to the track and to the axis of the pinion.

6. Window hardware as recited in claim 5,

characterized by the fact the L-shaped housing part is formed as a molded part on which the spacing members are in the shape of integral plugs with threaded bores.
