1 Claim.

This invention relates to multiple sash window hardware, and particularly to the hardware or operating mechanism for awning type windows in which the manipulation of one sash automatother sashes.

All automatically operating awning type window hardware known at the present time is diflibe done The reason for this is that it has been customary to manufacture such hardware in several separate parts.

These parts usually comprise an arm and hinge mined location. In these structures, the guide members are placed upon the frame as separate units so that accurate positioning of the guides and extreme accuracy in the milling of the sashes and frames is required to assure proper alignment and smooth operation. Likewise,

separate releasing mechanism is employed for,

where a disconnecting the sashes to permit of their independent operation, such mechanism must also be installed with absolute accuracy to insure its proper functioning with the sash and frame hardware.

ment.

A further object is to provide such hardware that .is readily adjustable upon being installed to fit windows of various dimensions and to accommodate variations in spacing and position of the several parts that may occur during installation.

A still further object is the provision of hardware of this character that may be fabricated and assembled at the factory in single units,

ing the sash and frame parts, the guide includmechanism for'the frame, and means for operatively connecting and disconnecting adjacent sashes.

One form of the invention is illustrated in the accompanying drawings, and described in detail in the following specification wherein advantages thereof are made apparent.

Fig. 10 is a perspective view of the same with the parts in the position illustrated in Fig. 9. a

The window shown in Fig. 1 is illustrative of one type to which the invention may be applied. This window comprises a frame 10 and three superposed swinging sashes illustrated at H shown in an open position and mounted for swinging movement so that all may be closed to completely close the opening in the frame In.

The sashes II are substantially identical in construction, and the hardware for each side of each sash ll comprises a sash plate l2 secured by screws to the edge of the sash and terminating at its upper end in a bent arm 13 which pro jects inwardly from the sash. A link I is pivposition.

The track II consists of a flat bar having its 1 edges flanged inwardly as illustrated in Figs. 4

and 10 so that it will slidably retain shoes that are guided for vertical movement by-it. The end of the arm I3 is pivoted to such ashoe which left-hand threaded screws slides in the track I1. The shoe to which the arm I3 is pivoted varies in construction depending upon the sash with which it is to be used. Referring to Fig. 3, a shoe for a bottom sash is illustrated at I9, while a shoe 20 is shown for an intermediate sash, and a shoe 2| for a top sash. Travel bars, presently to be described, connect these shoes to which the arms I3 are pivoted so that the sashes may be caused to operate simultaneously. These travel bars, however, may be installed after the other members have been applied to the sashes and frame. The unit, therefore, which comprises the sash plate I2, the link I4, the track I! and either of the shoes I9, 23, or 2|, as the case may be, is fabricated and assembled at the factory. It being understood that the track II used with each individual sash is a separate element, these units which are comparatively compact and easy to handle may be assembled and packed in readiness for application to the sash and frame. Three such units are illustrated in Fig. 2 as in their open position, and when they are closed, the members I2, I3 and H are substantially parallel so that they may be conveniently handled and packed.

The manner in which these units are applied to the sash and frame is best illustrated in Fig. 4 of the drawings wherein the sash plate I2 is illustrated as secured by screws 22 to the edge of the sash. There is usually a rabbeted shoulder, as illustrated, against which-this sash plate may be disposed to insure sufficiently accurate alignment thereof, but absolute accuracy is not essential. when both sash plates I2 are aligned against the rabbeted shoulders and secured to the sash, the sash is placed in position within the frame with the hardware in the position that it assumes when the sash is closed. The track II then naturally assumes its proper position against the frame member III where it is secured without further measurement or alignment by means of screws 23. After all of the sashes have been applied in this manner and the shoes thereof have been connected by travel bars in a manner to be described, a stop member I3 is set in place to conceal the operating mechanism.

The top shoe 2|, as illustrated in Fig. 3, is connected with the intermediate shoe 20 by means of a travel bar 24, a bolt 25 connects the upper end of the travel bar with the shoe 2|, and a pin 26 on the shoe 29 projects through a hole in the lower end of the travel bar. This pin may be loose-fitting so that the travel bar may be readily connected to it, the travel bar having suflicient resiliency to preventits coming off the pin. A slight inward bend may be given to the travel bar before it is installed to increase its tendency to spring inwardly and insure against its becoming disengaged from the pin 26. To make it possible to vary the distance between the shoes, each of the shoes 2| and 20 is formed in two parts having outwardly bent ends 21 connected by rightand 23. Turning of the screws 28 serves to vary the length of the shoes 20 and 2|, and thereby adjusts the effective length of the travel bars to accommodate sashes of different dimensions. The shoe 2|) is connected with the shoe I9 on the bottom sash by a similar travel bar 3|], the connection between the travel bar 30 and shoe I9 being a releasable one.

The lower end of the travel bar 33 is provided, as illustrated in Figs. 3, 8 and 10, with a slot 35 interrupted by a crossbar 33, and at the extreme bottom thereof are outwardly extending lugs 31.

The shoe I9 includes latching mechanism in the form of a latch member 33 and a tumbler 39,

both pivoted, as illustrated in Figs. 5 to '7, within a central vertically extending slot in the shoe. The back of the shoe I9 is shaped to slide within the track H (see Fig. 4), and side flanges extend forwardly from the edges of the shoe to guide the travel bar 3|) so that a slot 35 will register with the latch mechanism with the lugs 31 in a position to engage with the bottom edges of the flanges 40. In Fig. 3, the shoe I9 and latch mechanism carried thereby is illustrated in a position before it has been connected with the travel bar 30, but the normal operating position of the parts is that illustrated in Fig. 10 with the travel bar received between the flanges 40. The travel bar is resilient and is preferably given a slight inward bend so that its resiliency maintains it in position for cooperation with the shoe I9.

By means of the latch mechanism carried by the shoe I9, the lower sash may be operated independently or may be connected for simultaneous operation with the intermediate and top sashes. The lower sash is therefore referred to as the control sash, and it will be understood, as the description proceeds, that any one of the sashes may be used as a control sash instead of the lower sash through the use of such a latching shoe. The operation of the sash through the mechanism herein disclosed is similar to the operation of the sash in my copending application entitled Operating mechanism for multiple sash windows, Serial No. 10,379, filed March 11, 1935. Through this mechanism, opening of the lower sash or control sash causes opening of all the sashes. The control sash may then be closed independently. Upon subsequent opening of the control sash, it is again connected with the remaining sashes for simultaneous operation so that subsequent closing thereof closes the remaining sashes.

This operation is accomplished through the mechanism of the latch shoe I9 cooperating with the lower end of the travel bar 30 in the manner illustrated in detail in Figs. 5 to 10, inclusive. In Fig. 5 the parts are illustrated in the positions occupied by them as the control sash is being opened and the shoe I9 is moving downwardly in the track I'I, it being understood that the operation begins with all sashes fully closed. Crossbar 36 of the travel bar 39 is engaged by a shoulder 4| on the pivoted latch 3950 that the shoe pulls the travel bar 39 downwardly and causes opening of all the sashes toany desired angle as determined by the angle of opening of the control sash.

When the control sash is closed the shoe- I9 moves upwardly and, as illustrated in Fig. 6, the crossbar 36 slides over a projection 42 on the tumbler 39, springing the resilient travel bar 30 outwardly and permitting the'shoe I9 to move upwardly independently thereof. Thus the control sash or bottom sash has been closed, leaving the top sashes in their openposition.

Upon reopening of .the bottom sash, the shoe I9 again moves downwardly. The crossbar 36 first strikes the projection 42 on the tumbler 39, rocking that tumbler about its. pivot so that a finger 43 thereon engages a tail 4 on-the .tch 33 and swings the latch about its pivot toward the position illustrated in Fig. '7, the crossbar 3G finally striking and coming to rest against the latch to move it to and retain it in the position illustrated'in this figure. At this time the lugs amavu.

its original position at which the top sashes were left, this engagement between the lugs 31 and flanges ll pulls the travel bar downwardly and causes all the sashes connected therewith to follow the movement of the control sash.

Upon reclosing of the control sash, which again moves the shoe i8 upwardly, the travel bar springs from the position illustrated in Fig. 7 to that illustrated in Fig. 9 where the upper edge of the slot 35 therein engages with the top of the latch 38 and the travel bar is thus forced upwardly by the latch 38 so that all sashes are closed simultaneously. The parts remain in the position illustrated in Figs. 9 and 10, while the sashes are in their closed position so that upon commencement of the cycle 'of operation the downward movement of the shoe I! will, as illustrated in Fig. 5, again cause the shoulder ll of the latch 38 to engage with the crossbar It of the travel bar, restoring the latch to the posi- 25 tion of Fig. 5 and causing it to draw the travel bar downwardly.

While the invention is illustrated as applied to a window comprising three outwardly swinging sashes ,in' which the lower sash is employed to 30 control the others, it is to be understood that it is not limited to this form, but that it may be used in many types of windows regardless of the number of sashes, the direction that they swing, or the particular sash that is chosen to 35 control the others.

- Various changes may be resorted to in the construction and arrangement of the several parts of the invention herein described and illustrated within the scope of the appended claims.
