My invention relates to'tiltable windows and' more particularly to sash VWindows comprising vertically maintained lateral parts and a frame hinged in these parts.

Hinged windows are known which can be turned down -into the room for-convenient cleaningafter the means interlocking the .frame and the 'lateral parts have been released. It is, however, dangerous or undesirable if this release can beA effected by everybody, for example, by children or incompetent persons who may break the pane or may damage the mechanism of the Window o r may fall out of the window by carelessness. Objects of my invention are to make the interlocking and releasing means fool-proof, to prevent these meansfrom being operated inadvertently or by unauthorized persons, and to provide a stop for the release which can be removed only by a key.

Also Windows are known which can be tilted intol an oblique position adapted for ventilation. Such tilting does not involve the 'dangers mentioned before, and it is desirable that such tilting can be effected by handy and always ready means without the necessity of using a key. Therefore, other objects are to provide means interlocking the frame and the lateral parts in closed position of the window which means can be readily released as far as to pemii; the frame to assume an oblique position, but whichV are-stopped from being released into a position permitting the frame to turn down completely.

Further objects are to provide means to secure a window in closed or in partly opened position,`

to use the same means for these two purposes, to make these means releasable in two steps, to operate these steps by the same handy means, and to provide a removable stop preventing one of these steps.

Another object is to luse two separate lateral parts which are arranged slidably in vertical direction for a window of this structure.

Still other objects are to achieve these results with simple, inexpensive, effective and reliable means and Withmeans that will not operate accidently and that can be operated with a small force.

Still further objects and advantages will appear from the following description of an exempliiying embodiment of my invention, from the appended claims and from the accompanying drawing in which:

Fig. 1 shows a vertical elevation of -a window embodying my invention, most parts being shown in a -cross-section taken along the line I-I -of Fig. 2 and seen from the lower side in Fig. 2, the 55 right side of the window being shown broken off; Fig. 2 shows a horizontal crosssecti0n of the same embodiment, taken along the line 2-2 in Fig. l and seen from the upper side.

Fig. 3 shows a vertical side view of the same embodiment seen from the left side in Figs. 1 and 2, the left lateral part being shown in a crosssection taken along the line {im-3 in Fig. 2, the frame being shown'in an oblique position, a completely turned down position of the'frame being indicated-by dotted lines.-

Fig. 4 shows a vertical cross-section of the upper ledge of the window, taken along the line 44 in Fig. 2 and represented -on a larger scale.

yReferring to the drawing., numeral 5 -indicates the lateral parts, and 6 the frame or easement of the window. The-parts 5 may be connected to a building in an openingthereof in any known and suitable manner, for example, stationarily or slidably inserted between vertical rails '1.` The frame 6 is hinged to the parts 5 preferably by two horizontal pivots 8'positioned near the lower edge of the frame. A glass 4pane 9 is inserted in the frame 6 in conventional manner. A lever arm l0 is hinged to the lateral part 5 by a horizontal pivot IIy and is positioned between'this lateral part and the frame so that the'arm Ill canturn in a plane perpendicular tothe plane of the pane 9. Preferably, another identical lever arm IIJ is similarly positioned at the symmetrically opposite sidel of the window. `The arms I0 have open-` ings adapted to -be engaged -by bolts as will be described later. These openings may be formed, for example,by slots I2.. l f f The upper part or ledge of the frame 5 is hollow and may be formed by an upper horizontal -wall I3, a lower horizontal wallI4, an inner vertical wall I5 and an outer vertical wall I6. In the space surrounded by these walls, bodies II are positioned slidably in a direction parallel tothese walls. Preferably, one body I'I is arranged at each of the two ends of this space. The bodies I'l may have slotsV I8 through which bolts I9 and 20 afxed to the walls I3 and llv pass.l A bolt 2| is aixedto the outer end -of each body Il and projects therefrom in a lateral, horizontal direction. Theinner end ofeach body I1 has a recess 22 -in the bottom of which two steps are formed, one of these `steps formed bysa surface 23 and-the other step by a surface 24 having a larger distance from the outer end of the body II than the surface A23.

The ,bodies `II are permanently drawn to the l The bodies can be withdrawn to the inner sides against the action of the springs 25, preferably by exible means acting simultaneously on both bodies. For example, a cord or chain 27 is afxed to each body II, and these two chords are passed through openings 26 in the wall I4 and have ends hanging down and forming an united string 29 which can be easily pulled by a person standing on the oor of the room.

Stops areprovidedfor -the inward movement of the bodies I1 andmay be formed by' a member 30 having two arms eXtending into the recesses 22. tion, as shown in Figs. 1 and 2, thesearms are spaced from the bottoms of these recesses; The

member 30 is so movable or adjustable that itcan act as a stop by contact with either the surfaces 23 or 24. This adjustment may be made,`for eX- ample, by a turning movement of the membergSIlV which may be provided with pivots 3I passing through bores in the walls I3 and I4. v v

Preferably,y the adjustment' of the member 33 is made by means `of a special key fitting a key hole 3Ia in the wall I 5 and, after passing this key hole, engaging a recess 32 in the member 301whereby the key 33 turning in a vertical plane turns the member 30 suilioiently in a horizontal plane. When'the window is closed, the bolts 2| pass through the slots I2 of the lever arms I0 and also engage holes 34 provided co-axially in the lateral parts `5 as shown in Figs. l and2. Y,In this position of the window, the arms I are positioned vertically and contact stops 35 aixed to the lateral parts -5. Ordinarily the member-3D remains permanently in the position shown in the same iigures. l l

When a person pulls the string 29,` the bodies I1 slide inwardly until the surfaces 24 contact the member '30 and, at the same time, the bolts -2I leave the holes 34 and thereby releasethe frame `6 which, eventually by a slight further pull on the string 29, will fall down into the oblique position shown in Fig. 3 in full lines. In this position, the bolts 2I contact the lower ends of the slots I2, and the arms Illprevent further downfall of the frame 6, This position of the window is adapted for ventilation. The ventilation may be improved in 'conventional manner by a second window arranged below vor above the rst window and preferably constructed and operated in the saine manner whereby these two obliquely posi# tioned windows facilitate a circulating ventilation.

When the frame 6 is lifted again into'its vertical position, the bolts 2I automatically engage the holes 34 and secure the frame in its original position. 1 l

In order to open the window completelyor to bring it into a position convenient lfor cleaning, the key 33 is passed throughthe hole 3 la into the recess 32 and then turned until the arms of the member 36 are in line with the surfaces 23. This can be done whether the window is closed as in Fig, 1 or partly open as in Fig; 3. When thereafter a person pulls the string 29, the bolts 2| move to the inner sidev suriciently far as to leave theslots YI2 of the lever arms lIll whereby the frame 6 isfully releasedla'n'd can be turned down into the position shown inFig. 3 in dotted lines.

n Atthe same time, the lever arms I!) return into or remain in the vertical position shown in Fig.

3 in dotted lines. s

The frame 6 may be supported in the lowered Vposition and may be prevented from falling fur- 'ther down by suitable means, for example by arms 36 and 31. The arm 36 is rotatable around a When the bodies I'I are in their outer posi;A

pivot 38 afXed to the lateral part 5. The arm 3l is rotatable around a pivot 39 aixed to the frame 6. The ends of these two arms opposite to these pivots are connected with each other by a pivot 4i). When the window is closed the arms 36 and 31 are folded into parallel position. Similar arms 36 and 31 may be provided at the other side of the frame.

In order to secure the window again in closed position, it .is .only necessary to raise the `frame 6 until the window is shut, L`pulling, the string 2S. Then, upon release of the string, the bolts 2I reg turn automatically into the original interlocking position. Then, the key 33 may be used to turn `themember 30 into its original position.

I'desire it understood that my invention is not Y Vconiined to the particular embodiment shown and described, the same being merely illustrative, and thatmy invention may be carried out in other 530 ways without departing from the spirit of my invention as it is obvious'that the embodiment shown` and described is only one of the many that may-'be employed to attain 'the objects of my invention. i v
