Specification of Letters Patent.

Patented Jan. 3, 1911.

Application filed April 18, 1910. Serial No. 556,179.

To all whom it may concern:

Be it known that I, MARY KLEINEGGER, of Minneapolis, Hennepin county, Minnesota, have invented certain new and useful Improvements in Window-Guards, of which the following is a specication.

The object of my invention is to provide a removable guard for windows, designed, particularly, for sleeping room windows to positively prevent a burglar or any other person from entering the window by raising the sash or removing the screen.

A further object is to provide a guard which may be removed from the window during the day, if preferred, and which will not in any way interfere with the raising or lowering of the sash or the insertion or removal of the screen.

My invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings forming part of this specification, the figure is a view, partially in section, illustrating the application of my invention to a window.

In the drawing, 2 represents a window frame and 3 ferrules or sockets which are fitted into the side rails of the frame to be flush with the surfaces thereof. The guard consists preferably of a metal bar 4 and side bars`5 arranged parallel with one another and connected by rods 6, which are bolted gr otherwise secured to the middle and side ars.

7 and 8 represent fixed rods secured at Y one end to the middle bar and projecting through loops or staples mounted on one of the side bars, the ends of these rods projecting beyond the side bars a suiiicient distance to slip into the sockets on one side of the window frame when the device is in use. Similar rods 9 are mounted to slide in a similar manner on the opposite bar at the other side of the frame and are pivotally connected at their inner ends to one arm of bell cranks 10 which are pivotally mounted on the middle bar. The other arms of the bell cranks are connected with one another by a strap 1l, which is arranged vertically near the middle bar. This strap is capable of longitudinal movement to oscillate the bell cranks and project or retract the movable rods which, when projected, extend into the sockets in the window frame and lock the guard therein. Movement of the strap to releasethese locking rods is prevented by means of a padlock 12 or other suitable device which passes through a staple 13 on the strap and a similar staple on the middle bar. Movement of the locking rods will thus be positively prevented until such time as it is desired to take the guard out of the window. The padlock is 'then unlocked and the moving rods retracted to withdraw them from their sockets and the guard may then be removed from the window.

The device may be made in various sizes, according to the size of the window where it is to be used, and the number of locking rods may be increased whenever it is found necessary to do so.

The device may be made of any suitable material, preferably vertically arranged bars connected by cross rods to hold them in parallel relation.

I claim as my invention 1. A window guard comprising upright stationary bars and transverse rods secured to said bars and holding them in parallel relation with one another, locking rods having their outer ends projecting beyond said bars and adapted to enter sockets in a wmdow frame, the rods on one side of said guard being slidable longitudinally, bell cranks each having one arm pivotally connected with said sliding rods, means connecting the other arms of said bell cranks with one another, and means for locking said bell cranks against premature movement, substantially as described.

2. The combination, with the window frame jambs having sockets therein, of a window guard comprising upright side and middle bars, a series of transverse rods secured to said side and middle bars, rods, secured to said middle bars and projecting outwardly beyond said guard on one side and adapted to enter the window j amb sockets on that side, rods slidable in guides on the bar at the opposite side of said guard, bell crnks mounted on said middle bar and pvotally connected With said rods, and means for oseillatnv said bell cranks to project said sliding rodgs into the sockets in the Window jamb on that side of said guard, substantially as described.

In Witness whereof, I have hereunto set my hand this 15th day of April 1910.
