SASI-I HOLDER.

.Application filed October 19, 1927. Serial No. 227,330.

This invention relates to devices for holding a window sash in a set position and has for its object the provision of a simple and inexpensive device which will operate efliciently to hold the sash and by theuse of which the necessity of the usual sash weights and cords and pulleys will be obviated.

The invention provides adevice which may be easily applied to any window sashand which may be easily manipulated' to permit the sash to be raised or lowered when desired while, at the same time, operating automatically to'hold the sash in set position.

The invention is illustrated in the accompanying drawings and consists in certain novel features which will be hereinafter first fully described and then more particularly pointed out in the appended claim.

In the drawing:

Figure 1 is an edge elevation of a window sash having my improved holder applied thereto.

Figure 2 is a front elevation with parts in section, showing the device in position in a sash and showing its relation to the window frame.

In the drawing, the reference numeral 1 indicates a portion of a window sash which may be of any well known style and 2 indicates a portion of the window frame in which the sash is mounted for vertical movement. In carrying out the present invention an irregular recess is formed in the edge of the sash and this recess provides an upper chamber 2, a lower chamber 3, and an intermediate chamber 4 which tapers downwardly, as clearly shown in Figure 2. The intermediate chamber is lined with a backing plate 5 fitting closely against the rear wall of the chamber and may be cylindrical in its upper portion, the lower extremity of this backing plate providing a lip 6 which is engaged in an opening provided therefor in a face plate 7 and upset in said opening so that the lining and the face plate will be firmly secured together. The upper end of the lining or backing plate is bent forward or outwardly at a right angle to provide a top plate 8 which is likewise connected with the face plate and forms an abutment for an expansion spring 9 coiled within the intermediate chamber 4 and resting at its lower end upon a wedging ball 10. The face plate is provided with a slot 11 between its ends which slot is substantially co-extensive with the intermediate chamber 4 and provides an opening through which the. wedging ball may project to bind against the window frame 2,

asv shown clearly in Figure 2. The .upper portion of the slot is reduced in width, as shown at 12 in Figure 1, so that the edges of the slot form retaining lips wherebythe spring 9 will be held within the intermediate c iamber 4. It will be seen at once that the spring 9 tends constantly to expand and force the wedging ball to the lower end of the tapered portion of the chamber 4 so that it will be wedged between the sash and the window frame and thereby hold the sash in any posi tion in which it may be set. The invention is illustrated in the accompanying drawings as applied to the lower sash but it may, of course, be applied to the upper sash and when applied to the upper sash it will be relatively inverted, and it will be understood that any movement to open the sash will cause the wedging ball to wedge or bind more tightly between the sash and the window frame while closing movement of the sash will cause the ball to ride upwardly within thetapered chamber toward the wider end thereof and consequently automatically release the sash. In order that the ball may be held in an inoperative position while the sash is being opened, I provide a rock shaft 13 which is journaled through the stile of the sash and is equipped at'its outer end with a crank 14 adapted to swing transversely of the chamber 4 in the lower portion thereof below the ball so that if the crank is swung upwardly, the ball will be raised and release the sash, as will be understood upon reference to the dotted lines in Figure 1. Reverse movement of the shaft will, of course, permit the ball to move downwardly to lock the sash. To

manipulate .the rock shaft a handle member 15 of any approved form is mounted upon the inner end thereof so that it may be easily ,rocked when desired.

The face plate 7 is formed with lateral extensions 16 whereby to form bosses fitting within the respective chambers Q'and 3 and having their extremities turned outwardly, as shown at 17, so that supports and abutments for expansion springs 18 are provided. Openings are formed through the face plate in axial alinement with the bosses and guiding or running balls 19 are mounted in the bosses to project through said openings and engage the window frame, as shown in Figure 2, being held in constant engagement with the frame by the springs 18 in an obvious manner. The upper and lower balls 19 provide spaced bearing points for the sash so that it will be held to a vertical rectilinear path and any possible tendency of the sash to rock about the wedging ball will be overcome so that the sash will move easily at all times when an opening or closing force is applied thereto. The opposite side of the sash need not be equipped with the holder and the guiding elements but may run between the beads of the window frame in the usual manner, and it will be noted that the expansion of the springs 18 will cause the sash to move laterally with respect to the guiding or running balls and thereby effect a firm engagement of the sash within the groove of the window frame at the opposite side of the sash so that rattling of the sashwill be avoided. If so desired, a facing strip of metal may be applied to the window frame so as to minimize wear and avoid the formation of depressions or dents in the frame from the pressure of the several balls thereagainst. The wedging ball 10 is preferably given a roughened surface so as to in crease its wedging action, and the springs 18 are held against lateral displacement by side plates 20 at the upper and lower ends of the casing. p

The device is especially desirable for car windows as it will hold the window against rattling, notwithstanding the vibration of the car, while facilitating the opening of the window when desired.

Having thus described the invention, what I claim is:

The combination of a window sash having a tapered chamber in its stile opening through the outer edge thereof, a wedging ball mounted in said chamber, an expansion spring resting within said chamber and bearing upon the ball to hold the same toward the tapered end thereof projecting through the edge of the stile to bind against a window frame, a rock shaft mounted in the stile parallel with the front face thereof, and a crank at the outer end of the rock shaft in 'engagen'ient with the ball at the side opposite the spring whereby rocking of the shaft will release the ball from binding engagement Within the recess to permit opening movement of the sash.

In testimony whereof I afiix mysignature.
