FRIEDRICH OSKAR THIEM, OF ILEIPSIC, GERMANY.

SAFETY-WINDOW.

SPECIFICATION forming part of Letters Patent No. 295,594, dated March 25, 1884.

Application filed January 15, 1883.

To all whom t may concern:

Be it known that I, FRIEDRICH OsKAR THIEn, a citizen of Germany, and residing at the city of Leipsic, in the Empire of Germany, have invented a new and Improved Safety Window, of which the following is a specification.

The object of my invention is to construct the upper part of a window so that the `saine can easily be moved downward. to facilitate the cleaning of the same, and thereby prevent the usual danger in cleaning.

The nature of my invention consists in the construction of a window wherein the upper and lower sections are in one and the same plane, and having the upper section of the window arranged in a frame capable of sliding or moving downward when the lower section or window is quite open or is removed, said frame containing the upper section moving in a groove made in the sides of the main window-frame, whereby this upper section or window can be lowered downward whenever the same requires cleaning, thereby p reventing all danger usually resulting from. this operation, the groove in the sides of the main window-frame in which the upper section of the window or its frame is made to slide acting at the same time for the wings oi the lower sections of the window to close or nl,fold into for the purpose ofmaking the same airtight.

In the accompanying drawings, Figure I represents a front view of a window with the upper part or section made of one pane of glass or window. Fig. II is a horizontal section at line 12 12, Fig. I. Fig. III is a horizontal section at line 14 14, Fig. I. Fig. IV is a front view of a window, with the lower section of the windowremoved, and the upper part arrangedwith two panes, and moved down ward convenient for cleaning. Fig. Vis a section at line 16 16, Fig. I; and Fig. VI is a section at line 15 15, Fig. I, of the frame shown in Fig. IV, moved to the top.

Similar letters represent similar parts in all the figures.

G is the main framing, to which the frames of the several panes are attached.

J J are the two lower panes, hinged at a c to the main frame C, capable of being easily removed, in the usual manner, by being swung open and taken off from the pintles c.`

(No model.)

The upper window shown in Fig. I consists of one pane, A, and in Fig. IV of two `:frame D, so as to open inward similarly to the panes J J. The frame D, to which either the frame G, containing the single pane A, or the frame G', containing the double panes A', is hinged, fits into and is capable of moving in S-shaped grooves 1, as below described, and

is supported in its proper position upon a division-bar, B.

The-*sides of the main frame `C are provided on their inner surfaces with a single S -shaped groove, r-one in each side-into which the frames of the window-panes J J it and close, and into which the upper frame, D, is likewise -made to fit and capable of sliding downward in the same. (See Figs. II, III, V, and VI.) To enable the removal of the frame D, the groove r in the upper part of the main frame G is formed in a suitable strip, o, inserted in the upper part of said frame C, and capable of being easily removed by loosening the screwsn, which fasten these strips c to the frame C. (See Fig. VI.) When it is desired to remove the frame D out of the main frame C, this frame D must be first moved downward in the grooves r below these strips o, after which said Strips o are removed when the frame D is moved upward again, and can then be easily taken out of the main frame Gin the enlarged opening formed by the removal of these strips o.

Between the lower window, J J, and the up per frame, D, containing the upper window A or A A', a division-bar, B, is arranged, iitted to slide likewise in the S-shaped grooves o in the sides of the main frame C. This bar B is secured by suitable hooks or catches at its end to the main frame C, either in the position shown in Fig. I, or in any lower position, as shown in Fig. IV, and supports the upper frame, D, in these positions. When this bar B is in the position shown in Fig. I, the same acts likewise as a ledge for the upper end of the lower sections of the window to close against air-tight. This bar B may form the ICO lower part of the frame D, in which ease, when the upper section of the window is formed of one pane A, its frame niay be hinged to this bar B, and when the upper section of the window is formed of two panes, A A, the lower part of their frames will olose against this bar B air-tight.

It will be perceived that in whatever position the frame D is placed the frames G or G, containing the pane A or the panes A A, can

be opened, and the frame D cannot fall out ofthe l. In a window-frame, C, a single S-shaped groove, r, in eaeh side, in combination with the sliding frame D for the upper seetion of the window, and the hinged or French windows J J, forming the lower section of the window, folding or closing into said S-shaped groove 1^, and the division-bar B, substantially in the manner described.

2. In combination with a window-frame, C, and sliding upper frame, D, the side strips, o 0, in the upper part of the main window-frame, said strips@ o containing an S-shaped groove, r, forming a Continuation of the S-shaped groove in the lower part of the window-frame, substantially as and for the purpose set forth.
