. 1 This invention relates generally to improveL mentsin al1-"adjustable keeper or latching'device for" holding a window sash, which is hingedly to the upper portion of a window fratrie,l man open position.-

The main objects of this invention are to provide an adjustable 'window sash keeper device which is entirely automatic in-operation; to pro-'- vide'adevic'e of this character which mayv be readily and quickly -mounted on any hinged win-A dow sash and frame regardless of size; to provide a'device of this character whereby a window sash which is hingedly secured to the upper portion ofthewindcw frame may be securedly held open atranydesired angle without manual manipulaa tion-oi the keeper or latch; to provide a deviceofetliis character whereby a window hinged at its upperlend may be held open by this device and then-quickly closed without requiring any hand manipulation of the latchi-ng means; to provide azdeviee of this character where the window sash can belatched in an open position or closedby the-'same movement of the window sash; and to'provide-a device of this character which is relatively simple in construction and inexpensive to manufacture.

An illustrative embodiment of this invention is'shown in the accompanying drawings, in which:

Figure 1 is a front view of our invention shown secured to a window frame and sash, the frame and sash being shown broken away.

showing the window sash in dotted outline, in*

various raised positions and illustrating in dotted outline, the motion of the device of our invention.

1 In the drawings we disclose generally a window sash I, having a pane of glass 2 secured therein inthe usual manner, the sash being pivotally or swingably secured by hinges 3 within the side and" upper frames 4 and 4', respectively, in theV conventional manner. As is clearly illustrated Fig-1 of the drawings, the upper leaf ofthe hinge 3 is rigidly secured to the top frame 4 by screws' 5, or the like, while the lower leaf thereof is rigidly secured to the top bar I of the window sash l by screws 1, or the like. This is the usual type of window sash and frame found in basements. y

lhedevice of our invention comprises an L- shaped arm, preferably constructed of metal, the

long leg 8 of which is provided with spaced apertures 9 and I0 to receive the wood screws I3 for rigidly securing the arm to the' side bar I" offthe I'. The short legi I extends at right 'angles 2 to the leg Band is provided with an aperture |25 lll-normally vertically disposed swingingr` link :2.1'1411'32` has'an aperture 33 adjacent the uplp'er end thereof whichisadapted'toreceive a headed bolt A34, which threaded through the aperture 33 and the aperture I2' 0f 'the leg I'I whereby to pivotal-111, secure the arm 32 to the leg Il. The bolt"34fis provided with a nut 35 and a washer 36 positioned one on each side of the arm 32 to secure the arm 32 to the leg II and provide a bearing therefor respectively. A horizontally. disposed bearing rod or pin 31l is integrally se cured adjacent the lower endof the arm 32' in anysuitable manner such as by welding, riveting or the like.l The pin 31 extends laterally and'at right angles to the link arm 32.

A horizontally disposed elongated U-shaped bracket I4 (see Figs. 3, 6 and 7) also preferably constructed of metalis provided with a pair of feet I5 and I6 at the open end thereof, each disposed at right angles to the bracket I4. Each foot I5 and I6 is provided with an aperture through which wood screws I8 and I9 respectively are threaded to rigidly secure the bracket I4 to thel side wndow frame 4".

An' adjustable sliding metalblock 20 is adapted to nt loosely between the arms I4" and I4 which formsa guideway or slideway I1 therefor. blockZU is securely held within the slot I1 by a guide bar 2|, which is substantially equal to theI Width of the bracket I4, and which is positioned on the right-hand side of the bracket I4. A'

plate22, slide block 20, and guide bar 2I respectively, whereby said block '20 is slidably se` cured "within the. slideway I1. A pin or rivet 23 threaded'throughsuitable aligned apertures 3il'v and 3l 'contained-ln the latch plate 22 and 'slider block: 2u respectively, holds thel latch plate' 22" rigidly in a vertical positionv asA shown especiallyv The teeth 23` in Figs. 3 and 4 of the drawings; onthe latch 22 are'upwardly 'directed anddiagonally` disposed on the forward'edge of the latchv plate 22' whereby to forma plurality of notches 23.1A Whichfacei'fhe sash" I. The top and bottom of thelatch 22 are each 4provided with diagonally' disposed lrounded ends or cam-likev surfaces 22.! and :2;2 respectively.

Tile' pin 31 of 'the arm 32 is aligned with' .theA latch plate 22 and is adapted to seat in the notches" InV operationth'elatch plate-22 is" slid' into the deslredposit'lon on the bracket I4 by adjust ingthe sliding' block'rZU and'v securingit to thek bracket I4 by vtightening the nut 2501iv` the bolt 24. THe-window sash I is then-raised inwardly:

The"

Y A headed bolt 24 having a nut 25'; thereon is threaded through suitable aligned

apertures

26, 21 and`28 contained inthe latch' By further movement of the sash (to-jv that shown in dotted lines in Fig. 6) I the rod will automatically move upwardly'on vthe cam-like surface 22.2 and along the inner face edge of the latch plate 22 and seat itself in a notch 23.I and hold the sash in the position selected.

It will be apparent from examining Figs. 6 and 7 of the drawings that as the sash I is further raised at any time the pin 31 will also automatically slide out of the notches 23.I until said pin passes over the cam-like surface 22.I (see dotted line disclosure in Fig. 7) andv swings behind (or to the right as shown in Figs. 6 and 7) the latch plate 22, whereby tc'becom'e disengaged fromthe latch plate 22 and allowing the sash I to vbe closed against the window frame. It will be clear that as the notches 23.I are upwardly inclined the pin 31 is easily disengaged therefrom by merely lifting the sash I upwardly. y

It will also be apparent that the point at which the latch plate22 is secured to the bracket I4 will depend entirely on the length of the link arm 32. If, as shown in the drawings, the link arm 32 is substantially equal to the over-all length of the latch plate 22 then the latch plate 22 will be anchored to a point substantially in the center of the bracket I 4, However, if the link arm 32 is shorter than the latch plate 22, the latch plate 22 will be anchored closer to the to andv adjacent one edge of the window sash, bracket adapted to be secured yat one end to the window frame immediately adjacent said link arm and below the hinged upper end thereof to projectoutwardly from said window frame substantially perpendicularly thereto, a latch plate, means vadjustably securing said latch plate on said bracket at dierent distances from the plane of said window frame, said latch plate having downwardly inclined notches therein opening out of an upright edge of said latch plate facing the window sash, said latch plate being disposed transversely on said bracket and parallel to the plane thereof, and a stud on the free end of .said link arm disposed at right angles thereto and substantially parallel to the hinge axis of the link arm adapted for cooperative engagement with the notches on said latch bar.

3. A latch device for holding a window sash in open position and wherein the window sash is hingedly secured at its upper end to and within i said frame comprising an arm adapted to be sesash I and if the link arm is longer than the latch 'f plate 22, the latch plate 22 will be anchored farther away from the sash i. It will be equally clear then even though one link arm 32 is used the latch may be secured in various positions to which the window may be maintained in open position.

, It is to be understood that numerous details may be altered or omitted without departing from the spirit of this invention, as dened by the following claims:
