following statement :—
My invention has reference to an improved means for opening and closing
casement windows and the like, and consists of a stud plate or plates fixed to the
casement sash, on the axis of one of said stud plates I mount a worm wheel that gears
into a worm, (enclosed in a case of box form) on a rod, this rod is carried by two
brackets that are secured to the window frame, the said rod is actuated by means of a
hand wheel when it is desired to open or close the casement window to any required
distance. By the use of the abovementioned stud plates I dispense with the ordinary
butt hinges.
on
My apparatus is also applicable to casement windows of the rectangular form.
In lieu of abovementioned stud plates I mount a movable arm or arms
the same axis as the worm wheel, the said arm or arms work in slots in brackets
fixed to the casement sash or sashes, by this means one or more casement windows
can be opened and closed simultaneously.
