Be it known that I, ALFRED BECK, a subject of the German Emperor, residing at ueens borough, in the county ofaQueens and State of New York, have invented certain new anduseful Improvements in Safety of which the following is a Appliances,

The present invention relates to safety appliances for Windows and has for its object to provide a safety device'for protecting a person against falling through an openwinf dow. In many houses, and particularly in the poorer sections of the city, the windows often are very low, so "that when open accidents frequently happen to women trying to hangout clothes or children playingnear.

the window. r Fixedrallings or gratings arranged across. the window are objectionable, because they obstruct thelight and hinder the cleaning of and repairs to the Window. 7 a

To accomplish my object I provide a safety device whlch is so appliedto the-outside of the window frame, that at the open- 'ing of the lower sash it will beautomatically' swung across the window opening, so as'to form a safety railing or grating and on closing the window it will be lifted into a position in which it will not obstruct, the

To make my invention more clear, the same. is illustratedv in the accompanying drawing in which similar reference charac= corresponding which i I r Figure l is'an outerperspecti-ve View of a window equipped with nay-safety appliance; Fig. 2 is a sideview of the safety appliance and Fig, 3 is an elevation of a modified form of construction of the safety device.

Referring specifically to the drawing a, 6 denote the sashes of the window which in the window frameo. one of the counterweight casement-s of the window, a pinion d isarranged on across spindle e suitably borne in the window The pinion'rl is adapted toslightly the counterweight casement and to mesh with a rack section g fixed to the lower sash b of the window. The forward end of the spindle e projects outwardly, from the win- 7 dow casement and has fixed to it anarmfm. h

Projecting from the outside of the wink dow frame isapin or pivot z, onwhich is SAFETY APPLIANCE.
