Description

Jan. 3l, 1950 G. Z. GUINARD WINDOW SASH FASTENER Filed Oct. 25, 1947 3/ lNv'ENToR 650ML" Z 6am/Aw M. w vd ATTORNEYS Patented Jan. 31, 1950 UNITED *STAT ESS -PATENT/ferm This invention relates. to a window sash fastener of the type for locking a Awindow in a partially opened position, against further opening.
One object of the invention is to provide a fastener of the above type which is simple in construction and economical to manufacture. A further object is to provide construction which facilitates application of the fastener to the sash without the necessity ofV making precise preliminary measurementsr. y g v I Other and further objects and ladvantages will be made apparent in the following specification and claim.
In the drawing which shows an illustrative embodiment of the invention,
Fig. 1 is a sectional View showing the device applied to a sash, the window being closed;
Fig. 2 is a similar View showing the window slightly raised to bring the latch into normal locking position;
Fig. 3 is a similar view showing the parts in the extreme locking position;
Fig. 4 is a sectional view substantially on line 4-4 of Fig. 3 showing a plan view of the fastener;
Fig. 5 is a side elevational View of the fastener removed from the sash;
Fig. 6 is an end elevational view looking from the right in Fig. 5; and
Fig. '7 is a detail fragmentary sectional view showing a slightly modified rail element- Referring to the drawings the catch housing is shown as comprising a downwardly rearwardly inclined top member I, inwardly inclined side members 2 and outwardly extending flanges 3 by which the housing is secured to the top horizontal frame member of the lower sash of a window. Members I, 2 and 3 preferably, and as shown, are formed integral from a single sheet of suitable metal. Pivoted within the housing is a catch member 4 formed with side extensions 5 which engage in bearing openings 6 formed on the side walls adjacent the rear end of the housing. A finger piece 'I extends from the catch member 4 outwardly of the housing. The bearing openings are positioned adjacent the bottom of the housing and the forward extension of the catch member is such that when the finger piece is pressed downwar'dly to swing the catch to the top of the housing, as shown in dotted lines in Fig. 5, the foi'- ward edge of the catch member lies flush with or extends only slightly beyond the top edge of the housing. The catch member has its maximum extent from the housing when in its lowermost position as shown in Figs. 3, 4 and 5.
The flanges 3 are provided with openings 8 for window sash is an elongated channel member i2 of desired length. yThe side flanges I3 of the channel -member are formed with vertically spaced opposed notches as indicated at i4. The web of the channel member is formed with openings I5 for the reception of'screws Iii by which the channel member is secured to a side member II'oftheupprsash.
In applying the device to the sash the channel member is rst screwed in place as shown in Figs. l-4. With the window closed the upper and lower horizontal frame members I0 and Il, respectively, of the lower and upper sashes are drawn tightly together, as shown in Fig. 1 either by pressing the sashes together or by means of the conventional cam lock, not shown, with which the windows are usually provided. With the sash in this position the housing is placed on the frame member I0, and with the linger piece 'l depressed, is moved toward the channel member I2 until the forward edge of the raised catch member 4 engages the fianges I3 as shown in Fig. 1. The housing is then secured in place by screws 9.
The upper and lower window sashes are customarily guided in their vertical movement between outer and inner guides I8 and I9. Usually there is a slight play between the sash frames and the guides as indicated by the spacing at 2@ in Fig. 1. This spacing is shown exaggerated in the drawings Vfor the sake of clearness. Within reasonable limits my improved construction provides proper operation in spite of looseness of the sash in the guides. For example, assuming the degree of play shown in Fig. 1, when the lower sash is slightly raised the forward edge of the catch 4 engages in the lowermost notches I4 and, on continued upward movement of the lower sash, spreads the upper and lower sashes, wedging them tightly against the guides as shown in Fig. 2, preventing further opening movement. Where the sashes are exceptionally loose the catch may move to its extreme lower position as shown in Fig. 3.
Additional security may be obtained by forming the notches in the channel member as slightly more than a semi-circle as shown at 2| in Fig. '7.
As will be obvious when finger piece 'I is held depressed to maintain the forward edge of the catch member 4 in its uppermost position the lower sash can be raised, or the upper sash lowered, to any desired extent and the catch re leased to engage in any selected pair of notches I4. Thefwindow is thereby locked against increased operiing but may be closed without resistv ance, the'y catch sliding ratchet fashion in the closing direction of movement. It will also be seen that the top of the housing prevents the catch from being thrown into an inoperative position by Aa s'harp' blow on tleoutsi'de: of thev sash as is the case in many prior art devices of this type.
What Iclaim is: A
A sashffastener combination whichnpiises' a housing' 'consisting of a single pieeofsheet metal the center vportion of saidgsheet` prviding'ad'wn'- wardly and ,rearwardly inclindftp' member: wider? at its forward edge than at its v rear edge,inter mediate side portions of the sheet being bent downwardly to formrrea'rwardly converging verf tical side walzls'ad theside" e'dge ptis beingl bent outwardly'tlpiovide horiiot'alf ags, saidfiangc's" Being fied with op`enings`v fo' I' tachingrthe housing to the lower sash -of awiiidow; the so-*forin'ed ihg Being cpletely p'e' at' its forward rviid's; al catch plate in the form nieta-l wider at its forwa d" end l. .afdlrtfiffig opposed trunnjinportions' which freely' and pivotally engage in openings formed in the side walls of the housing closely adjacent the lower edges of said side walls at the rear of the housing, the forward edge of said catch plate extending slightly outwardly of the forward end of the housing and the rear end portion of the catch plate extending outwardly of the rear end of the housing to form a nger piece, said rear end portion of the catchplate being bent upwardly along af line clsly adjacent to, and tol the rear of, said trunnions to lie in a plane at an angle to the plane of thev forward portion of the catch plate. and' a channel member adapted to be secured to tlieppif'wndow casing, the horizontally spaced free edges of the sides of the channel being forned' with a series of vertically spaced notches selectively engageable by the forward edge of the catch plate when the latter is swung to a position below'thetop of the housing.
