This invention relates to improvements in windows and it has particular relation to a window construction wherein slides having sashes mounted on them are adapted to be moved vertically in stile grooves.

The main objects of the invention are to provide a window construction in which the sash is pivotally mounted on a slide and adapted to be moved about a horizontal axis and swung inwardly to a slight extent for the purpose of ventilation; to provide a window construction that when opened for ventilation the sash portion thereof is maintained in locked relation with the frame portion thereof; to provide a plurality of means for maintaining said sash in position for ventilation, said means operating in conjunction with each other to prevent inadvertent opening of the window to a substantially horizontal plane; to provide a window construction in which certain elements co-act to form an exceptionally weatherproof window.

The above being among the objects of the present invention, the same consist of certain features of construction, combination of parts to be hereinafter described with reference to the accompanying drawings and then claimed, having the above and other objects in view.

For a better understanding of the invention, reference may now be had to the accompanying drawings, forming a part of this specification, in which:

Fig. 13 is a vertical sectional view of the latching device taken substantially on line 13-13 of Fig. 12.

In the particular embodiment of the invention disclosed in the drawings a window frame 10, is provided with stile grooves 11 and 12 formed therein. As shown in Fig. 3, the grooves 11 and 12 are formed by spaced members 13 and 14, rigidly secured to opposite sides of the frame and longitudinally thereof in any suitable manner, such as screws 15, each portion having an inwardly extending flange 16, and by parting strip members 1'7 disposed midway between the members 13 and 14 and secured to the frame by screws 19. The parting strips 1'7, are provided with flange portions 18 extending toward the flanges 16, the surface of the flanges 16 and 18 adjacent the frame 10, being disposed in alignment with respect to each other.

Vertically slidable in the grooves 11 and 12 are upper and lower slide portions 20 and 21 respectively each of which are provided with portions 22, extending at right angles from the main body portion 23 thereof, to form members substantially of channel section, the open sides of which are disposed outwardly with respect to the frame 10. Each of the portions 22 may be provided with shoulder portions 24, extending the full length of the rear margin and adapted to fit in grooves formed by the frame 10 and the flange portions 16 and 18. These coacting flanges and grooves form a weatherproof joints for the window. Relatively flexible metal strips 25, disposed between the parting strips 1'7 and the frame 10 are provided with portions 26 extending between the flanges 18 and the shoulder portions 24 and are provided therefor to assist in forming a particularly efficient weatherproofing joint adjacent the parting strip 17. The slides 20 and 21 may be provided with inwardly projecting flanges 2'7 and 28 respectively which extend the full length of the outer margin. Disposed. against the flanges 2'7 and 28 are sash plates 30 and 31 respectively, each having inwardly extending longitudinally disposed ribs 30a and 31a. The rear edges of the sash plates abut the flange portions 27 and 28 respectively, when their sashes 32 and 33, secured rigidly to the sash plates 30 and 31, are disposed in a vertical plane. A pair of grooves 34 and 35 are formed adjacent the inner margins of the slides 26 and 21 respectively and are provided to receive outwardly and rearwardly extending projections 36 and 37 on the plates 30 and 31 respectively, so that the cooperating portions function as weatherstripping when the sashes are vertically disposed. Portions 38 and 39 of the sashes 32 and 33 are each provided with angularly disposed surfaces, having an ofiset portion thereon to form a weatherproof joint as indicated at 40.

As the mounting of the upper and lower sash plates and their slides are identical, I will now describe in detail the mounting of the lower sash 33 on the slide 21, reference being had to Figs. 4 to 10 of the drawings.

Extending outwardly from the sash plates 31 adjacent their lower extremities are hinge pins 42, extending through the lower end of the slides 21 and are held in position in any suitable manner. Pivotally mounted within the channel shaped portion of the slides 21 and intermediate of their length are resilient spring-like members 43, which are provided to support locking pins 44, extending through slots 46, formed in the slides 21. Disposed in the outer margin of the sash plates 31, recesses 48 may be formed which are so positioned that when the sash plates are vertically disposed their base forces the pins 44 rearwardly against the tension of the member 43, but when the sash plates 31 are moved forwardly at an angle to its slide 21 the pins are also moved forwardly by the springs 43, which support them.

Secured against the frame 10 and within the channels formed by the slides 21, are catches 49 having slots 50 formed therein in such relation to the pins 44 as to receive the pins when the sash 33 is pivoted on the pivot pins 42 and both the sash and the sash plates 31 are elevated. When the sash is parallel with the sash plates 31, the pins 44 will not be engaged by the slots 50 because the inner extremities of the recesses 48 so hold the pins against the springs 43 that they pass beyond the catches 49.

Disposed on the inner side of the sash plates 31 and, intermediate their ends, in depressions formed by the partial removal of ribs 30a, are arms 52, each arm having a sliding membr 53 pivotally mounted at one end, as indicated at 54, and being pivotally mounted at the opposite end of the slides 21, by means of a bolt 56. The arms 52 are spaced from the slides 21 at their points of attachment thereto a sufficient distance to allow the sash plates 31 to fit between slides 21 and the arms 52. Slots 57 in each of the sash plates 31 are adapted to receive the bolts 56. The arms are so placed that, in the normal position, the arms are disposed between the sash plates and the sash as shown in Fig. 7, with a flange portion 58 of the slide members 53 adapted to travel in a groove 59 in the sash 33 as indicated in Fig. 5.

As shown in Figs. 4 and 6, safety locking devices 61 are provided to maintain the sash and sash plates in an angular position for ventilation and prevent the sash from being inadvertently opened to a horizontal plane. However, the sash 33 and sash plates 31 may be opened to a horizontal plane as shown in dot-and-dash lines in Fig. 4, as will hereinafter be apparent.

As shown in Figs. 6 and 7, each locking device 61 may be provided with a lever member 62, pivotally mounted on the outer face of the portion 23 of the slide 21, by a bracket 63 secured to the portion 23. The member 62 is provided with an angularly disposed portion 64.adjacent one end thereof, said portion extending rearwardly with respect to the frame, and at the opposite end thereof terminates in a portion 65 disposed at right angles thereto, the portion 65 terminating in a wedge shaped portion 66, adapted to fit in openings 67 and 68 in the slide 21 and sash plate 31 respectively. The portion 62 is normally held in contacting relation with the outer surface of the arm 52, by means of a spring 69, of any suitable construction, disposed adjacent the portion 64. When opening the window for ventilation the arm 52 moves inwardly until the portion 66 fits into an opening 71 of the arm 52, which limits the movement of the sash.

When releasing the locking device 61 from engagement with the arm 52, for opening the window to a substantial horizontal plane, it is necessary to move the slide 21 and sash 33, upwardly in a vertical plane until the angular portion 64, of the member 61, contacts with a surface '72 (Fig. 8), of a flanged member 73, secured to the window frame 10 and disposed at a predetermined distance above the locking device 61. In operation the window is raised with the portion 64, first contacting with a curved surface '74, of the member '73, after which the member 64 moves along said curved surface until the portion 64 contacts with the surface 72, which forces the portion 64 inwardly until the lever 62 is disposed in the position shown in dot-and-dash line in Fig. 6. As shown in Fig. 6, the wedge shaped portion is withdrawn from the opening 71 of the arm 52 which, under normal conditions, would allow the sash to assume a horizontal position, but because of the device hereinafter described the sash is prevented from doing so.

In order to guard against accident and to pro vide a device for locking the window in a partially open position, the sash 33 is provided with locking devices '76 one of which is arranged on each side of the window adjacent the upper extremity thereof. Openings 176 are formed in each side of the sash 33 for the reception of the locking devices 76, each of the openings being formed by cutting away a part of a rib portion 1'77 which separates two channels 178 formed in each edge of the sash edges, and extending longitudinally thereof.

At opposite extremities of the openings 176 the rib portions 177 are notched as indicated at 179 to provide steps 181 upon which latching units 78 of the locking devices 76 are rigidly secured by screws 183 extending through the opposite extremities of the latching units and into the steps 181. The latching units 78 comprise bars 77 partially filling and substantially closing the openings 176 and on the inside of which leaf springs 80 and 187 are secured by screws 186 between the bars and the steps 181 at the lower extremity of the openings 176. The upper extremity of each of the leaf springs 80 has rigidly secured therto, by means of a screw 185, a pin 82 which projects through a transversely formed opening 188 in each of the bars 77 and into aligned openings 84, 85 and 86 formed in the arms 52, the sash plates 31 and the sides 21 respectively. The openings 84 in the arms 52 are somewhat large for the pins 82 as is indicated 'at 189 in Fig. 11 for a reason which will hereinafter be set forth.

Semi-cylindrical openings 191 are formed in the bars 77 in transverse relation to the openings 188 and directly beneath the latter. Semi-cylindrical cams '79 disposed beneath the springs and 187 in the semi-cylindrical openings 191 are rotatable therein by shanks 192 formed integrally between the cams '79 and operating handles 90 for the latches. The shanks 192 extend through openings 193 formed between the openings 176 and the front side of the sash 33. In these openings are disposed annular flanges or bushings 194 in which the shanks 192 arerot-atably mounted and which project inwardly from front plates 8'? secured on the front of the sash 33 by screws 196. The inner extremities of the flanges 194 are provided with arcuate notches 88 which cooperate with pins 89 extending though the shanks 192 to limit the possible rotation of the handles 99 and consequently the rotation of the cams '79.

It is apparent that rotation of the cams '79 will progressively remove the pins 82 from the openings 86, and 84 in the slides 21, the side plates 31 and the arms 52 respectively.

In operation the sash 33 may be opened either vertically or by angular movement thereof as desired.

In opening the sash vertically it is necessary only to lift upon any convenient part of the sash, and the sides 21, the sash plate 31 and the sash 33 all will move upwardly as a unit.

In the event it is desired to open the sash to any desired extent by angular movement thereof, the handles are simply moved inwardly at the bottom until the pins 82 are withdrawn from the openings 86 in the slides 21. The top of the sash is then pulled outwardly, as indicated in Fig. 4, until the wedge shaped portions 1 66 of the members 61 engage the openings 71 in the arms 52. This limited angular movement of the sash disengages the pin 44 from the openings 48 in the sash plates 31 and permits the pins to move under the influence of the springs 43 into a position just beneath the catches 49.

The sash 33 is then elevatedto a slight extent and so consequently are the slides 21 elevated until the pins 44 carried thereby slide within the notches 50 in the catches 49 which are secured to the frame 10 of the window. The sash, the

slides, and the sash plates cannot then be further elevated but simultaneously with the movement of the pins 44 into the openings 50, the angular portions 64 of the latching members 61 engage the sloping surfaces 74 of the earns 72 and so move the latching members 61 as to release the wedge shaped portions 66 thereof from the openings 71 in the arms 52. When this event occurs the sash 33 will drop slightly by angular movement upon the pins 42 until the portions of the arms 52 at the extremities of the openings 84 limit any further movement of the sash.

In this position the window can be moved neither angularly nor vertically ,except from within the room, as will be hereinafter described, and therefore the window may be said to be locked in a partially opened position.

The sash, however, may be further opened into the position indicated by the dot-and-dash lines in Fig. 4 simply by further turning the handles 90 inwardly until the pins 82 are entirely removed from the openings 85 and 84 in the sash plates 31 and the arms 52. This removal of the pins 82 from the aforesaid openings entirely releases the arms 52 and permits the sliding members 53 to move until they engage the opposite extremities of the grooves 59 in which they are mounted.

To close the window the sash 33 is again pivoted on the pins 42 until it assumes a vertical position and then is pushed downwardly.

From the foregoing description it is apparent that I have provided an improved window construction, one in which the window cannot be inadvertently opened, thus providing a window that is more efiicient than the window heretofore employed. In addition, by the combination of parts and features of construction above described I have provided a window in which certain portions thereof co-act to provide an exceptionally efiicient weatherproof window.

While I have shown in the drawings a particular illustrative view of my invention, and have described the elements and functions thereof in detail, various modifications may be made in the same, and in the various features of construc tion, without materially changing the invention therein, and formal changes may be made in the specific embodiments of the invention described, without departing from the spirit or substance of the broad invention, the scope of which is commensurate with the appended claims.
