W. F. KLEIN WINDOW CASEMENT CONTROL Filed Dec. 23, 1925 WWW/km Va/b.
Patented Mar. 29, 1927.
V UNITED STATES PATENT OFF-ICE.
WILLIAM KLEIN, OF ST. LOUIS, MISSOURI.
VINDOXV-CASEMENT CONTROL.
Application filed. December 23, 1925.
My invention relates to controls for window sashes and particularly to that class of sashes that are hinged on one side and held in any desired position by means of an adjustable fastener.
The object of my invention is to provide a window casement control that is positive in operation and automatically locks the window at any point desired between the closed position and 90 deg. open.
Another object of my invention is to provide a window casement control that can be used either on top of the window sill or beneath it without leaving an opening from the interior to the exterior of the house.
Other and further objects and advantages of my invention will be apparent from the description, claims and drawings, in which:
Fig. 1 is a plan view of a window partly broken away, showing my device in operative position.
Fig. 2 is a vertical cross-section on the line 22 in Fig. 1.
lVhile quite a number of casement controls are now in use, all are subject to the following objections Even the most popular controls must be installed upon the top side of the window sill, so that they not only are exposed to View and must, therefore, be highly finished,
but they interfere with dusting and cleaning the window sill.
Another objection common to the controls now in use is that they do not automatically look at any desired point.
A still further objection is that those now in use require an additional lock to securethe sash when the window is closed.
To obviate these disadvantages andto overcome the objections above set forth, I have devised a simple, compact, cheaply constructed and highly efiicient window control that automatically holds the window in any position when released, and one that can be inserted through the apron of the window or on top of the sill with equal success.
My improved casement control comprises two movable members 1 and 2, pivotally connected at 3 to form a toggle joint. The opposite end t of the member 1 is pivotally joined to a bracket 5, which in turn is securely attached to the lower edge of the sash 6, while the opposite end 7 of the member 2 is pivotally joined by means of a pivot bracket 8 to the sill 9, or the finish 10.
Serial No. 77,274.
The member 2 is slotted at 11 andarticulates by meansof the pin 12 inserted through the slot 11 and held in place by the reciprocable barrel 13, having its opposite end 14 screw-threaded internally and adapted to be engaged by the worm 15, said Worm being held against longitudinal movement by means of an escutcheon 16 rigidly aflixed to the apron 17. A crankarm 18 is rigidly attached to the Worm 15.
It is obvious that when the crankarm 18 is rotated in one direction, it will cause the barrel 13 to move outwardly, rotating the arm 2 about its pivotal point 7, which in turn will transmit force through the member 1 causing the toggle joint to approach a straight line, thereby holding the easement 19 in any desired position rotating it about the hinge 20.
It is likewise obvious that a reverse movement of the easement will take place when the crankarm is rotated in the opposite direction. It is, also, apparent that the casement 19 can be firmly held in any position from a closed one to an open one at 90 degrees; hence, when the easement is entirely closed, it is automatically locked, thus saving the expense and necessity of having an additional fastener.
A metal escutcheon 21 may be used to guide the barrel 13, or a small opening can be made through the stool 22 to serve the same purpose.
Having fully described my invention and its method of operation, what I claim as new and useful and desire to secure by Letters Patent is A window casement control, of the class described, comprising a horizontally reciprocable member internally screw-threaded at its inner end adapted to be reciprocated by a rotatable member fixed against longitudinal movement and having its outer end externally screw-threaded adapted to engage the screw-threaded portion of the said horizontally reciprocable member, a crank attached to the inner end of said rotatable member by which said rotatable member may be rotated, a link bar pivotally attached to a window sill and adapted to be rotated with said pivotal joint, said link bar being longitudinally slotted through approximately one-half of its length nearest the said pivot joint and adapted to be slidably engaged by a pin rigidly fixed in the outer end of said reciprocablemember, the said link bar being hingedly attached to a second link bar at its outer end, the said second link bar being adapted to be hingedly attached to a hinged member adapted to be attached to a} window casement, so that when the said crank is rotated in one direction, the window casement Wlll be caused to close, and when the crank is rotated 1n the opposite direction, the window casement 1 my signature this 18th day of December; 20
