Claims.

This invention relates to improvements in brackets designed to adjust and hold storm windows, other hinged windows and hinged devices at various angles, the main object being to provide a device particularly adapted for holding hinged storm windows rigidly and silently in closed or selective open positions. A further object is to provide certain new improvements over my patent applications, Serial Numbers 272,048, filed April 23, 1928 and 352,572, filed April 24, 1929, as hereinafter fully disclosed'and illustrated in the accompanying drawing, in which,

Fig. 1 is a vertical sectional View of the lower portion of a house window frame and a storm window thereof, held in outward position by my device.

Fig. 2 is an edge View or inside elevation on a plane designated by line 2--2 in Fig. 1 showing the storm window closed and my device in lowered folded position in full lines and in upper locked position in dotted lines.

Fig. 3 is detail view as on line 3-3 in Fig. 1 with the storm window closed and latched by a certain spring catch engaging the stile bracket of my device.

Fig. 4 is a detail sectional elevation through the stile bracket pivot member of my device as on line 4-4 in Fig. 1 and showing a screen window attachment adapted to serve as a catch engaging said pivot member.

'Fig. 5 is a sectional detail View on a horizontal plane as at 5-5 showing a hinged window catch of the type illustrated in'Fig. 4 but engaging another part of the stile plate.

Figs. 6 and '7 are respectively top and side elevations of the stile bracket pivot member or button B in enlarged scale.

Fig. 8 is a transverse sectional view centrally of the said button as on line 88 in Fig. 6 showing also the stile plate and the inner knee joint arm of my device'in two positions. 1

Fig. 9 is a perspective View of the connected knee joint members of my device, the inner one of which is shown with a modified catch engaged by the outer one when the arms are folded together.

Referring to the drawing by reference numerals, 12 designates the window sill, and 13 a vertical side member of the window frame. In said side piece 13 is fixed the usual parting strip 14 forward of and against which a storm window 15 bears when in closed position. 'Rearward of the parting strip 14 the upper and lower house window sash are slidably retained in any suitable manner not illustrated.

In Fig. 1 the lower end of the storm window is shown pushed out from the frame, it being assumed of course that it is pivotally suspended from its upper end (not shown). The vertical side frame memberv of either side of the storm 60 window is designated 15A, this designating also 1930, Serial No. 425,309 (or. 292-263) corresponding members of a screen window. Only one of my improved window brackets is shown, the right hand one, the left side one being a counterpart thereof.

My bracket device comprises in part a foldable knee-brace of two pivotally connected parts, an inner arm 16 and an outer arm 17, the latter pivoted at its outer extremity on a headed pin 18 retained in a window bracket 19 secured as at 20 to the inner face of a window bar 15A. In this joint a fibrous Washer W is inserted on pin 18 between arm 1? and the bracket face (see Figs. 2 and 9) and the pin is riveted to press the fiber washer therein, providing a silent friction joint.

The said bracket 19 is fixed a certain predetermined distance above the bottom of the hinged window. The arms 1617 are adapted to fold up parallel to each other on a vertical plane, the inner end of the inner arm having a bore 16B, said bored part adapted to be frictionally and removably retained on a pivot-button 13 mounted to project from a stile plate 21 fixed as with screws 22 to the spacing strip 14, the plate being elongated vertically and preferably of a width slightly less than the width of the said strip 14 and said pivot button being on th'elower part of 21. This button, and certain construction of the knee-joint or connected parts of the arms 1617 and certain locking means for said arms presently to be described involve the new and useful construction of this invention over my applications herein referred to.-

The arms 1617 are formed at their pivotally connected parts, each with an enlargement com-v prising a round head 16I-I17H, as the case may be. These heads are spaced apart by a washer 23 preferably of fibrous material. 24 is a bolt passed through the washer and said heads'with its head adapted to be drawn toward the outer face of head 161-1 by a nut 24N which together with the bolt is stationary with relation to arm 1'? but rotates in head 16H. Between the head of the bolt and adjacent face of head 16HI place another 'non-metal, preferably fibrous washer 23A (see Fig. 2) to prevent metal contact and provide another friction member in the knee joint. Obviously adjustment of nut 24N creates any degree of frictional contact on both sides of washer 23 and simultaneously on washer 23A between the head of the bolt and the face of head'lfiI-I. Thus there are no metal surfaces in contact, referring to'the'rotary parts and the desired friction is easily obtained to hold the arms 16-17 at desired angular positions and the hinged window 15 in any corresponding position.

The arms 1617 are of like length, referring to the center-to-center distances from their com mon pivot to their respective other pivoted ends 18 and 1613. The window bracket'19 andstile plate 21 are so fixed that when the swinging window is closed its pivot 18 is in direct alinement with the pivot-button B of the stile plate and the arms 16-17 are then in parallel relation and depending from the said alined pivot means as a common pivot (see full line showing of arms 16-1'7 in Fig. 2).

The button B comprises a special feature of this invention. It comprises a single piece of spring sheet metal with an elongated ,flat base B2 from the central part of which the metal is bent upwardly in two opposite parts and in arouate form transversely to provide a 2-part tubular neck B3 and the upper parts of said neck parts enlarged and pressed inwardly to provide two opposite head pieces B4 forming a two-part hollow bead.. As these two integral neck and head parts are counterparts and spaced apart there will .be'two opposite longitudinal slits or. openings B5 between them. The button is fixed to the stile plate by forcing its head end through an aperture 21A in the plate, the parts of the said head springing toward each other when passing through and then plate B2 is brought up against the stile plate, the neck part B3 of the button being retained in aperture 21A, the head B4 being held outwardly of the plate as distinctly shown in Fig. 8. The inner end of bracket ar 16 is pivotally and removably fixed on the button B by simply forcing its apertured end part 16B over the head of the button toward plate 21 until said apertured part passes over the head, after which the button springs back to normal condition and arm 16 is pivotally mounted on theneck part B3 between said head and the adjacent face of plate 21 (see Figs. 1, 2 and 8).

To remove arm 16 from this pivot mounting a screwdriver blade or other suitable tool isinserted between arm 16 and plate 21 and arm 16, forced away from the plate and over the head B4 of the pivot button.

' Now it will be readily understood that the knee-brace type of window spreading device I have described is readily attached to or detached from the stile plate at B, and in case of removal of the storm window the knee-brace is simply folded up close against the storm window to be stored away with it, only the stileplate 21 remaining permanently on the frame piece 14. In most cases after astorm window has been thus removed it is immediately replaced by a screen window which may also be represented by 15 in the drawing. For such latter windows I provide means other than knee-brackets as described for removably engaging one or more parts of the stile plate 21 as will now be described. 7

25 and 26 are respectively lower and upper tongue pieces integral of plate 21 both above the pivot-button B and of which 26 projects from the plate a short distance while 25 is at the front edge of the-plate extending outwardly and thence in an inclined plane away from the plate 21 as best shown in Figs. 3 and 5.

17F is an inward extension from the head 17H of the outer knee-brace member providing a finger hold. As previously set forth the two kneebrace members depend vertically from the alined pivots 18 and B when the hinged window is closed, said two bars comprising thus a single arm which may be swung up, inwardly, to vertical position above their common pivot to the dotted line position shownin' Figs. 1 and 2, where the two bars are retained between the two projections 25 and 26.

An equivalent of this is formed in my former application Ser. No. 352,572 but this device is improved, comprising the angular part of tongue 25 under which the bars 16 and 17 are wedged toward the plate 21. The collective bars when swung up must be swung away from plate 21 in passing tongue 26;. V

In Figs. 1 and 3, 2'7 is a spring lock or clip: fixed as at 28 to the window sash 15 just above bracket 19 and formed with a curved part 27A at its free end inwardly of which is formed a shoulder 2713, said clip being located so as to frictionally engage and snap over the end of stileplate tongue 25 and hold the hinged window in closed position (see Fig. 3). The clip is easily released by forcing the end 27A out to disengage shoulder 2713. In Figs. 4 and 5, 29 is a spring catch similar to 27 'but made for screen Windows particularly when nov knee-brace isto be used. This catch is fixed as at 30 and inwardly of its shoulder 298 provided with an aperture located so as to snap over the head of button B (Fig. 4) and is of course readily released therefrom by springing it outwardly. In Fig. 5 the catch 29 is assumed tobe so, located on the screen sash that when such screen is closed the shoulder part 29S engages the end of. tongue 25 of the stile plate. Either mounting of catch 29 is optional.

In the modification Fig. 9 the bracket arm 16 is provided with an elongated integral flange 16F opening forwardly from itsrear edge, said flange being of L-shape in cross section and adapted to receive and hold the other arm 17 Within its opening when the two arms are swung together to parallel position. When the two arms are subsequently swung up to top position the said flange 16F will be forward and bar 17 is prevented from spreading away from bar 16 by any outward pressure on the hinged window. This eliminates the need of either or both tongues 2526 of the stile plate.

The entire device has now been fully disclosed and its operation disclosed simultaneously. Only such parts of my other applications as have been necessary to mention have been included in this specification to clearly identify the improvements made. The noiseless friction joint, including the exterior and interior fabric (non-metal) washers in the pivoted connection of bars 16 and 17 is stressed. The simple but highly efllcient and inexpensive pivot-button B is also particularly stressed.
