The embodiment of the invention illustrated comprises
a support including the base member 1 and top member
2 which coact to provide a housing for certain of the
operative parts. The base member 1 is desirably formed
of sheet metal stock and has upwardly offset laterally
spaced arm supponting portions 3, its end portions 4 being
adapted to be secured to a window sill or other support

force through the offsets 37 which is highly effective, that
is, there is leverage action and even a sash which has

with frame pants or the leverage is such that the window
may be forced open and this without damage to the
mechanism.
The actuating arms 21 are relatively thick as compared
to the links 26 as is illustrated in FIG. 5, so the arms do
not bend under 'any ordinary stress. The links are de
signedly relatively ?exible and that is desirable because
the bottom of the sash or other closure raises as it is
swung outwardly. The pivotal connection for the links
with the sash ‘avoids subjecting the connecting pivots to
any undue stress.
The offsets 37 and the links 26 permit the links and
arms to collapse into partially overlapping relation as
illustrated in FIG. 3, and with the sash attaching member

adaptations, as it is believed that this disclosure ‘will en
able those skilled in the art to embody or adapt the in
vention as may be desired.
Having thus described the invention, what is claimed
as new and is desired to be secured by Letters Patent is:
1. In a window operator, a support comprising a base
55 o?sets in said links being such as to permit the links to
lie in substantially parallel and partially overlapping rela
tion to the arms when the arms are in fully retracted posi
tion, and a strap-like sash attaching bracket provided with
spaced pivoted link coupling members to which the outer
ends of said links are pivotally connected, said bracket
being substantially parallel to said arms and links when
the arms are in fully retracted position.

bers having upwardly project-ing lugs on their upper edges,
larly disposed upwardly projecting portions at their outer
ends, coupling links pivotally connected to the said up
wardly projecting outer ends of said actuating arms, the
