This. invention- relates to. regulator. mechanism

tlíose used on automobile bodiesior;operatingthe
same'between openiand closedV positions.
An object is to produce a new and improved
window regulator of the above type having a pair
of swinging arms in the shape of bell cranks, the
free ends of the arms being slidingly connected
to the adjacent edge portion of the window glass
and the opposite end portions being intercon
nected in such manner that a rectilinearly shift
able operating member may be employed for con
jointly actuating said arms to impart the desired
window movement.
Other objects reside in details of construction,
assembly and operation hereinafter more fully
described, and for purposes of illustration but not
gageablè.. It. wíllÍbe. understood that’ a crank

gaging the upper side off'tlie actuating bar 49" and
a stud 56 engages the opposite side of the bar
thereby to guide the longitudinal or rectilinear
movement of .the bar.
In operation of the regulator mechanism above
described, it will be understood that swinging
movement of the bell crank levers 42 and 43 is
effected in response to longitudinal movement of
the bar 49 in one direction or the other thereby
raising or lowering the Window glass 12a. During
this movement the lever 42 swings about its pivot
