However, the parallel arm reg window panel, the balance arm. being positively ulatonwhile inherently providing a desirable re controlled from the‘mounting- plate so as to swing motehandle location, has thedisadvan-tage. of oppositely to and past the main arm during two arms swinging equal ‘distances in the same .35 operation. and at» such compensated speed as to direction thereby tending to shift the glass. lat cause its point- of. connection with the window erally. The compound gear regulator, while panel to travel. the same. vertical distance or to avoiding this disadvantage by, reason of having have the samerange of travel as the point of two-diverging arms which swing equally in op~ connection of the main arm. with the panel posite directions, fails inherently to provide a. 40 although traversing a shorter path.

Also, in this regulator the points of connection of the arms tovthe glass have undesirably too wide a spreadin the half provide animproved window regulator including a. pair. of diverging swinging arms- adapted to be connected at their..-o.uter ends to the lower edge way position. The cross arm regulator has the 46 of. a window panel for. raising and'lowering the disadvantage of' requiring two separate supports. same, one. of the arms being. shorter than the for the arms, one arm being pivoted to amount ing plate and the other slidingly connected at- a distance therefrom to the inner door or body panel. This. renders installation more dif?cult and more expensive as compared with the two other .and pivoted thereto. intermediate. the ends of. the. latter, the: regulator including. driving imeans- folswinging thelong-er arm and aposi tiverconnection. between the shorter arm. and the regulator 'mounting plate. ‘or support. for previous mentioned regulators which require a single mounting plate for both arms.’ An important object of the present invention is to provide aiwindow regulator of the two arm swinging. the shorter arm. oppositely to. and past thelonger arm during. operation. of the regul lator,_- the constructionv being. such . that, although 65 the’. arms have different. speedsv of». travel, the 2,410,363 3 4 . ventional manner about an up and down axis in termediate its front and rear edges to swing lat points of connection of the arms with the win dow panel have substantially the same range of travel thereby maintaining the window pane] erally.

'The arm 21 at the juncture of the arm portions 21a and 27b thereof is pivoted in overlapping relation at 28 to the main or driving arm 22, so that the'ang'le ‘portion 21b of the shorter arm forms a depend ing angular extension of the arm portion 27a.
