SAFETYrGARATI NG.

SPECIFICATION forming part of Letters Patent No. 655,492, dated August 7, 1900.

Application iiled April 12, 1900. Serial No. 12,565. (No model.)

T0 @ZZ whom it may concern:

Beit known that I, HERBERT W. KINGS- BURY, (Whose post-office address is 7 7 West Third street, Vinona, Minnesota) a citizen of the United States, residing at Winona, in the county of Winona and State of Minnesota, have invented certain new and useful Improvements in Safety-Gratings; and I do declare the following to be a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference bein g had to the accompanying drawings, and to the letters of referencen marked thereon, which form a part of this specification.

This invention relates to an improved safety-grating for windows, and has for its object the provision of a simply and durably constructed appliance of this character which is adapted to be positioned -to iill the windowopening when the sash is raised, the grating when so positioned being securely held against displacement, whereby forcible entrance is effectually discouraged.

The invention consists of the construction and arrangement `of parts set forth in detail in the following description and shown in the accompanying drawings, in which- Figure l is a View in elevation of a window with my improved safety-grating in position. Fig. 2 is an enlarged view in perspective of the safety-grating, dotted lines showing the sections partially folded.

Referring to the drawings by letter, A denotes my improved safety-grating, which is in practice adapted to fill the window-opening at the top or bottom dependent on which sash is moved. The grating is composed of two sections, each of which is comprised of a number of horizontal bars a ce and vertical bars b b, the bars ct being formed from fiat strip metal or other suitable material and the bars b being made from rod metal or other suitable material. The bars a are preferably apertured to receive the bars b, and any suitable method or means may be employed to The ends of one of the bars b are brought beyond the upper and lower bars ct ct to provide pins b b2, the purpose of which will be presently explained.

The sections of the grating are hinged together centrally, a pintle-rod c being passed through the lapped ends of the bars a a, said ends being preferably halved, as shown. The rod is rigidly secured to the bars a of one section, but is passed loosely through apertures in the bars a of the other section. The ends of the rod c project beyond the top and bottom bars ct a, providing pins c' c2. At the -outer side of each section is a vertical bar d,

which is recessed or apertured to receive the ends of the bars a, and said bar CZ is of such width as-Will insure its iitting snugly in the windowframe, thereby preventing lateral play.

In practice, supposing the grating is to fill the space below the lower sash, said sash is raised to a height in excess of the height of the grating, and the grating being first partly folded is introduced into the space, with the bars Zagainst the frame. The grating is then bent, and as it straightens or unfolds it is wedged in the space, after which the Window is lowered. The window-frame is provided with sockets which receive the lower gratingpins Z22 c2, and in the under side of the sash are sockets which receive the upper pins b c'. With the sash lowered on the grating no movement of the latter is possible, in viewof the positive engagement of the pins and sockets, and by the use of the pins b. b2 to supplement the pins c c2 entrance by removing the frame-beading and by swinging the grating ends outwardly or inwardly is prevented. The sashes are locked or secured together by any suitable fastener accessible from the inside, so that movement of either sash from the outside is rendered impossible.

' When secured in position, the grating effectually prevents forcible entrance and affords the best protection against burglars= and in addition the grating forms all of the functions of-a lifeguard. The grating is quickly removed by elevating the sash, raising the grating, and folding it sufficiently to bring its side out of engagement with the frame. The grating is to be made of different sizes to fit dierent widths of windows. If it be found that a grating is slightly Awider than the window, one of the bars d can be readily removed and the bars a'shortened, after which the bar d is replaced.

The grating although very-efficient in pracloc ing two sections each consisting of bars se- I5 cured crosswise of each other, said sections being foldably secured together centrally on a pintle-rod the ends of Which are extended beyond the grating to form pins for engagement with sockets in the sash and frame, and zo other pins on the grating for engagement with other sash and frame sockets.

In testimony whereof:l I affix my signature in presence of two Witnesses.
