9 Claims.

The present invention relates to window sash holders, and more particularly to an improved window sash holder adapted to be utilized in connection with conventional wood, metal, or wood and metal windows of the sliding sash type.

Frequently, in windows of this type, the counterbalance instrumentalities become inoperative, in which event, the lower sash will not remain open, and the upper sash will not remain closed, in the case of double-hung windows, thus requiring either repair or replacement of the old counterbalance means.

However, this is a task which requires, in most cases, the services of a skilled carpenter or other mechanic, due to the tedious and difficult nature of this work.

Therefore, it is highly desirable that there be available a suitable window sash holder that can be readily utilized to take the place of the conventional counterbalance assembly of a window, either at the time of manufacture or installation of a new window or when such assembly becomes inoperative, preferably without requiring the services of any skilled labor.

Accordingly, it is a primary object of this invention to provide a window sash holder which may be simply and readily installed on conventional window assemblies of the sliding sash type when the old counterbalance assembly becomes inoperative, or, on the other hand which may be installed on new window assemblies in lieu of the conventional counterbalance means, either at the factory, or at the time of installation of the window.

Another object is to provide a window sash holder which allows the window sash or sashes to be raised and/or lowered, as the case may be, and which positively holds the sash in any selected position intermediate the fully open and the fully closed position.

A further object is to provide a window sash holding means which includes a holding member that is slidable in a channel shaped bar which defines one side of the Window sash-receiving channel in which the sash is customarily slidable, and which in the case of double-hung sashes, may be, if desired, readily utilized to replace the conventional parting strip that separates the two slidable sashes of a double-hung window assembly, or which may be substituted in lieu of the conventional parting strip at the place of manufacture of the window.

Other objects and advantages of the invention will hereinafter become more apparent and the novel features thereof defined in the appended claims.

In the drawings:

Figure 1 is a fragmentary View in elevation of a typical double-hung window assembly embodying the sash holder of this invention, as viewed from the inside of the building of which the window forms a part, with a portion of the window frame broken away for clarity;

Figure 2 is a view similar to that of Figure 1, but showing the window assembly as viewed from the outside of the building;

Figure 3 is a view in vertical section as taken on the-line 33 of Figure 1, with the sash holders shown in their sash-holding positions and in wedged interengagement with the channelshaped parting strip;

Figure 4 is a view in horizontal section as taken on the line 4-4 of Figure 3;

Figure 5 is afragmentary view in vertical section as taken on the line 5--5 of Figure 4; V

Figure 6 is a fragmentary view of that portion of the upper sash,.its sash holder, and the asso ciated channel strip and window frame parts shown in Figure 3, with a portion of the mounting bracket broken away and shown in section, but showing the wedge member in a released position relative to the channel strip to allow the upper sash to move downward; and 1 Figure 7 is an exploded detail view in perspec tive of the supporting bracket and pivotal wedgecarrying rocker arm that are utilized particularly for the lower sash.

Like reference characters designate corresponding parts in the several figures of the drawings, wherein I generally denotes a window frame, including conventional stop strips defining a pair of

channels

2, 3, in which the window sashes are slidable, and a central groove 4 adapted to accommodate a parting strip 5 of a suitable type.

In accordance with this invention, the parting strip 5 has the form of a channel-shaped strip which is secured in the groove 4 by means of a suitable number of screws 6 or the like. This parting strip 5 forms the inner side of the two sash-

receiving channels

2, 3, and defines a groove parallel thereto which is adapted to cooperate with the sash holders generally designated 1, 8 carried by the upper and lower sash members 1', 8', respectively.-

The upper sash holder! is mounted on the lower horizontal edge of the window sash 1- and adjacent to one lateral side thereof in operative sash-holding relation to the channel strip 5, and the sash holder 8 is mounted on the upper horizontal edge of the window sash 8' and adiacent to one lateral side of this window sash and also in operative relation to the channel strip 5.

The sash holders I, 8 are constructed so as to cooperate with the channel strip in the same manner, and while in the illustrative embodiment, this channel strip constitutes a parting strip, it could be utilized as one of the stop strips on the window frame, particularly in the case of a single-hung window assembly, but its function as a stop strip or a parting strip is not essential if the groove defined thereby is formed in some other part of the window frame.

Referring particularly to Figures 2 to 6, it will be seen that the upper sash holder 1 comprises a laterally disposed supporting bracket including a base plate 9 which is adapted to be secured to the lower edge of the sash l by means of a suitable number of screws or the like, as may be desired, and a vertically disposed portion ll having a laterally projecting lug l2 disposed on one side thereof.

A rocker arm I3 is pivotally mounted on the vertical portion ll of the bracket, as by means of a shouldered pivot pin or rivet 14 having a reduced end l5 receivable in an opening IS in the vertically disposed portion l l of the supporting bracket.

This rocker arm I3 is provided with a laterally offset sash-holding lug I! which is adapted to project into the open channel of the parting strip 5 and frictionally engage the opposed sides of the parting strip with a wedging action that prevents the window sash T' from being lowered when the rocker arm I3 and the lug I! are in the position shown in Figures 2, 3 and 5, but being adapted to disengage from contact with the parting strip 5 when the rocker arm :3 is pivoted to the position shown in Figure 6 in order to permit the window sash l to be lowered. As is best seen in Figures 2, 3, and 5, the lug I1 is substantially square in form, although it may be of any other suitable form, but it is preferably provided with a pair of diagonally opposed relatively sharp corners, as at ll, to increase its resistance to movement of the sash when these sharp edges are wedged between the opposed walls of the channel strip 5.

The rocker arm i3 is preferably formed with a substantially vertically disposed rigid actuator l8, and the adjacent upper edge H) of the rocker arm is so arranged as to butt against the lower edge of the window sash I (see Figure 6) when the rocker arm and the lug I! are moved by the actuator 18 to the released position shown in Figure 6 and the window sash is rendered free for downward movement, with the lug l1 and its sharp edges l'l' completely free from engagement with the channel strip 5.

Disposed between the lower edge 28 of the pivotal rocker arm 13 and the opposed portion of the laterally projecting lug [2 on the vertical portion ll of the supporting bracket, is resilient means, preferably having the form of a compression spring 2| which is seated at one of its ends in a recess 22 in the laterally projecting lug l2, the opposite end of the spring 2! butting against the lower edge 20 of the rocker arm l3, thus constantly urging the rocker arm l3 and consequently the sash holding lug l7 into frictional wedging engagement with the channeled parting strip (see Figures 2, 3, and 5).

Passing now to the sash holder 8 mounted on the upper edge of the lower window sash 8, it will be seen that this sash holder is generally similar to the hereinbefore described sash holder 1, except that it is provided with a modified form of actuator means which renders the sash holder 8 readily actuatable when the window sash 8' is in a raised or open position, which would normally elevate the sash holder 8 to a position beyond the reach of the average person.

The sash holder 8 includes a supporting bracket having a base plate 23 secured to the upper edge of the window sash 8' by means of suitable screw fasteners 24, a vertically disposed rocker armsupporting portion 25, and a laterally projecting portion or lug 26. A rocker arm 21 is pivotally mounted on the vertical supporting member 25, as by means of a shouldered pivot pin or rivet 28, in the same manner as has been hereinbefore described in connection with the rocker arm [3 and pivot pin M of the sash holder 1.

This rocker arm 27 is also provided with a laterally offset sash-holding lug or wedge member 29 having diagonally opposed relatively sharp edges 29' adapted for frictional wedging engagement with the channeled strip 5 in order to hold the window sash 8 in any position of elevation, the lower edge 30 of the free end of the rocker arm 21 being slightly inclined in order to permit the rocker arm to be pivoted to a sash-releasing position, with the sash holding lug 29 centrally disposed in the channel 5 and out of engagement with the opposed walls thereof, as limited by abutting contact against the upper edge of the sash 8'.

A resilient compression spring 3| or the like is interposed between the lug 2B of the supporting bracket of this sash holder 8 and a springseating portion 32 of the rocker arm 21, one end of the spring 3| being seated in a socket or recess 33 in the lug 26, and the opposite end of the spring seating on the portion 32 of the rocker arm 2?. This spring acts to constantly urge the rocker arm 21, and consequently the sash-holding lug or wedge 29, into frictional wedging engagement with the parting strip 5.

Means are provided for conveniently actuating the rocker arm 27 into sash-releasing position against the urge of the spring 3 I, this means preferably comprising a vertically disposed pusherrod 34, which is preferably U-form in transverse section, so as to receive the outer end 35 of the rocker arm 2'1. A pivot pin 36 extends through the pusher-rod 34 and through an opening 37 in the end 35 of the rocker arm 2'! for pivotally connecting these elements together.

The lower or free end of the pusher-rod 34 is preferably provided with an offset handle or finger-piece 3B, and intermediate this handle 38 and the point of connection between the pusherrod 34 and the rocker arm 2?, the pusher-rod 34 is slidaoly secured to the window sash 8 by means of a suitable fastener 39 which extends through a longitudinally extended slot 46 in the pusherrod 35.

The operation of the hereinbefore described Window sash holding means is as follows, and it will be assumed that both the upper and lower sashes l, 8 are in the closed position shown best in Figures 1 and 3 of the drawings.

When raising the lower sash 8, for example, any holding action of the sash-holding lug 29 is released automatically as a result of the rocker arm 21 pivoting slightly against the spring 3! responsive to the downward drag imposed on the lug 29 by the channel strip 5 upon initial movement of the sash 8 towards an open position.

Now when upward movement of the sash 8' is stopped, the spring 3! forces the rocker arm 27 to pivot in the opposite direction, the lug 29, particularly the sharp edges 25 thereof, engaging the opposed walls or faces of the channel strip 5 and becoming frictionally wedged therebetween, the weight of the window sash causing an increased wedging action as the sash tends to slide back down. Thus, the window sash is securely held in a raised or open position.

When it is desired to lower the window sash 8', it is only necessary to apply a slight pressure upwardly on the handle 38 of the pusher-rod 34 to cause the rocker arm 2'! to pivot in a direction to move the sash holding lug 2% to a position out of engagement with the opposed faces of the channel strip 5, and the window will slide down freely by its own Weight, until it abuts against the window sill, or until the pressure on the handle 33 is released to allow the sash-holding lug 29 to again engage the channel strip 5 to hold the window in any new position.

The operation of the upper sash holder 7 is the same as that just described, except that the rocker arm is pivoted to the sash-releasing position by a slight pressure outwardly, or to the left as seen in Figure 3, on the rigid actuator arm l3 thereof, thus moving the sash-holding lug H to the position shown in Figure 6.

Now, it Will be seen that I have produced a novel and improved window sash holder that may be readily and simply installed on existing windows to replace the conventional counterbalance assemblies with which they are generally provided, or on the other hand, which may be installed on new window assemblies in lieu of the conventional counterbalance means, either at the factory or at the point of installation. Still further, I have produced a sliding sash holder that is easy and smooth in operation. and which is extremely eflicient and positive in its action.

While the specific details have been herein shown and described, the invention is not confined thereto, since changes and alterations may be resorted to without departing from the spirit thereof as defined in the appended claims.
