The sprocket wheel l15` is fixed upon a stub shaft 16 journalled in the channeled guide plate 13 and a base plate 17 secured `to .the

car body adjacent the upper extremity vof the regulating mechanism. The stub vshaft 1 6 also carries a gear'wheel 18 adapted to mesh with a pinion 19 loosely mounted on the stub shaftA 2O ALto which the handle y21 is fixed, means being provided between the liafndl'e and the pinion19 lior automatically as lcikiiglmenibers and aske'ys Afor "connect-l ingfthe pinion and plate with the mecha# nislmL carried *by the handle 2,1 presentlyto be described.

The pinion and associated mechanism is shown in Fig, 4c as located at the right hand side ot' the gear wheel 18, and in such position is adapted to raise and lower the win-` dows on one side'ot the car. To raise and lower the windows` on the opposite side ot the car, identically the saine mechanism `is employed but the pinion 19 and the n'iechiinism associated therewith on the handle shaft 20 is mounted on the left hand side oit the gear wheel 18.' ln' Fig. i is shown an opening il in the guide plate 13 in which the shaft 20 is adapted to be journalled when in position on the lett hand side of the gear While it will be apparent that the illustrated embodiments ot my invention here- 1' in disclosed are well calculated to adequately fulfill the objects and advantages primarily stated, it is to be understood that the invention is susceptible to variation, modiiication and change within the spirit and scope ot the subjoined claims.
