HTTORNEY Patented June 24, 1947 UNITED STATES PATENT OFFICE WINDOW GUARD John L. Mayer, Kansas City, Mo. Application October 22, 1945, Serial No. 623,786 9 claims. (o1. v16o- 34) This invention relates to window guards of the character combinable with window frames defining an opening wherein Slidable sash are po-sitioned and is a continuation in part of my copending application, Serial No. 583,303, filed March l1'7, 1945, for Guarded window assembly.
'I'he primary aim of this invention is to providel a guard for windows of the sliding sash type wherein the folding or collapsible grille of the guard may be released from its anchored condition and bodily raised as a unit with the window sash while it is housed behind a suitably disposed apron.
Another important aim of this invention is to provide means for releasing the lower portion of the grille from its attachment with the window sill, which means is operable only when the window sash to which the upper part of the grille is attached, is in the lowered or closed position. This invention has for a yet further object to provide structure for locking the sash and grille of the guard against movement at any point in the path of travel of the sash for the purpose of holding the window openpart way and precluding unauthorized persons from shifting vthe Window sash toward the open or closed position from a place outside the building of which the window is a part.
Other aims of the invention lare important and will be made clear during the course of the following specification referring to the accompanying drawings, wherein:
Fig. 1 is an elevational view of a window assembly having a guard thereon that is made pursuant to the present invention.
Fig. 2 is 4a view similar to Fig. 1 b-ut showing the lower portion of the window frame with the sash and guard in a closed condition.

Fig. 8 is a sectional view on an enlarged scale sectional View taken l and looking in the 2 taken on line VIII-VIII of Fig. 1 and looking in the direction of the arrows.
Fig. 9 is a fragmentary detailed enlarged sectional viewtaken on line IX-IX of Fig. 1, and Fig. 10 is a fragmentary detailed perspective view illustrating the locking element and manner of releasing the locking bar from a point near the top of the window sash.
The window guard chosen for illustration embodies the preferred form of the invention and is chosen to be associated with a window frame generally designated by the numeral I2 within Vwhich is slidably mounted a pair of sashes I4.
The lower sash I4 slides to the position shown in Fig. 1, from the closed position illustrated in Fig. 2 and in so doing, the grille I6 of the guard is extended to be positioned across the opening formed by window frame I2 and that is normally closed by sash I4 when the latter is shut.. This grille I6 comprises a number of horizontal members I8, each provided with a bearing 20 to slide along vertical rails 22, one of which is mounted at each side of window frame I2. Rails 22 each comprises a tube 24 and :a rod 26 reciprocably mounted in tube 24 for movement toward and from a position where it-s lower end will interlock anchoring strip 20 and locking bar 30. A perforation 32 in strip 28 registers with a hole 34 in bar 30 when said bar is in a position to allow normal movement of grille I6, as sash I4 is raised.
A series of links 36 pivotally secured as at 36 to members I8 have their ends articulated as at 45 and the rivet 40, which pivotally joins links 35, has its heads on each end thereof housed within opposed channels forming each member I8. These channels embrace bearings 20, as clearly shown in Fig. 10.
Anchoring strip 28 is secured to sill 42 of window frame I2, as shown in Figs. 4 and 5, and the ends of this strip 28 are rebent to threadingly receive the lower end of tube 24 through which rod 26 is passed. There is a locking bar 30 at each end of member I8 attached to the lowermost portion of grille I6 and each bar 30 has a pintle 44 secured thereto and projected through a slot 45 in the outer flange of the said lower member I8.
An apron 46 having a bayonet slot 48 therein adjacent to each pintle 44 allows movement of pintle 44 to shift bar 30when the guard or grille I6 is in the position shown in Fig. 2. Such shifting of pintles 44 will move bar 30 toward and from a position where the hole and perforation 34 and 32 respectively wil1` register to receive rod 26.
The upper end of tube 24 gaged by a bracket 50 that has a swingable L- shaped member 52 pivotally mounted thereon as at 54. A notch 56 receives rod 26 when the parts are in the position shown in Fig. and head 58 on rod 26 precludes the rod from dropping back into the locked position when member 52 is in the place shown in Fig. 10. The upper end of member 52 has asalient 6D thereon that is eccentric to the pivotalconnection 54 and which strikes the surface of sash I4 when it is in the raised is threadingly enposition shown in Fig. 1 to preclude the lifting Where it will unlock bar 3i) and allow disconnection of the lower part of. 'grilleof rod 26 to a place I6 from sill 42. Thus a safety feature is present in that the lower Dart of grille I6 cannot be disengaged from sill 42 when sash Member 52 assumes the position shown in Figs. 1 and 2 when rod 26 is interlocking bar 8U' and strip 28. In such position head 58 lies beneath member 52 and cannot be lifted until the member is swung around pivot /54land` out of the way of head 58.- Such swinging cannot occur when the sash i 4 is open. Guide rails 22 are rigid to window frame I 2 and means is provided for interlocking both the sash-I4 and grille I6 in any position throughout the path -of movement of the sash. This means comprises `a latch member 62in1the formfof-a hook partially eircumscribing each lrail 22"and extending through apron 46 to threadingly receive `a manually manipulable knob 64.54 When the knobis loosened no tight engagement between member 62- and rail 22 is established and free relative movement of these parts is permitted. Ifv for example sash I4 is stopped part way up and it "is desired to secure the sash and grille assembly in that place, knobs 64' are tightened and member 62- will grip rails 22 to preclude accidental movement.
In many instances it is desired to open sash I4 'without havinggrille I6 vextend across the opening formed-in window trarne I2. Under such conditions and with sash I 4 in the lowered position, arms 52 are swung'out from above heads 58, 'rods 26 are moved up out of engagement with lockingbars 38,' and member 52 is allowed to swing back wherefnotch 56'receives rod 26. In thisl position bars 3 are moved inwardly from beneath the inturned ends of anchor strip 28 by manually manipulating pintles 44 within bayonet slots 48. When the sash is lifted again pintles 48 will holdthe lo'wermost member I8 of grille I 6 in a connected condition with respect to apron 46 Tand all of members I8 in a, collapsed unitary condition will be lifted with sash I4. The grille I6 will be completely housed behind apron 46 and between this said apron and-the lower portion of window sash I4.
This possibility of manipulation allows' both upper and `lower sashes I4 to' be washed as is now the custom, and by manipulating these sashes to different exposed positions in the opening formed by window frame I2.'- When lower sash I4 isl elevated, only the upper member I8 receives a lifting or motivating forceto extend all parts of grille I6. The connection between apron 46 and uppermost member I 8 is through the medium of a-biiurcated bearing 66 between the legswhereof hook 62`is confined, as shown in Fig. 6.
From the foregoing it will beapparent that disconnection of the lower portion of grille I6 cannot occur when sash I4 is elevated and therefore, the safe guarding ofthe opening across which grille I6 is extended, will always be possible without fear of unauthorized persons on the `outl 4 is raised.
side of the window disconnecting the grille from its anchored condition. It will also be manifest to one skilled in the art that the bodily lifting of the collapsible grille I6 may occur with minimum amount of manipulation and that the collapsed grille I6 may be hung from the lower portion of the window sash without obstructing the view through the glassed portion of sash I4 nor through the opening formed Within frame I2. Thisl because apron 46 is but slightly wider than the width of the lower element of sash I4 and the entire guard is confined to an area across the opening of window frame I2 which is not objectionably greater than that occupied by the lower frame member of the sash I4.
The Abroad ideas embodied in the window guard illustrated and described are capable of embodiment in structure having arrangements of parts andrappearances dilTerent than those illustrated and therefore, it is desired to be limited only by the spiritV of the' invention/and scope `of the appended claims.
