Serial No. 490,845.

This inventionhas to do broadly with the art of windows and is more particularly conment of the. window in additionto the usual sliding action.

. At the present time'such propositions as the washing of windows, the replacement of broken window-panes, and other similar work exposes the persons carrying out such work .to some little danger due to the fact that it is necessary to climb out into position in which access may be had to the exterior surface of the window-pane. With this condition in mind, this invention has in view as its primal object the provision of a window construction which includes the two' sash frames that slide up and down in the usual manner but which are mounted in the win dow frame so as to afford not only the sliding action, but also a swinging movement which may be effected to position either 'or 7 both of the sash frames in a position in which the exterior surface thereof is accessible from the interior of the building in which. the window is located.

In carrying out this idea in a practical embodiment, certain problems arise which must be properly taken care of in order to provide a commercially feasible construction. In order to provide the swinging action on the part of the sash frames, it is necessary that they be pivotally mounted at one side. Such pivotal or hingeconnection in itself is not adequate to provide a good seal against weather conditions which heretofore has been afi'orded by the conventional slide and groove constructions. In accordance with this invention a weather strip arrangement is availed of in conjunction with the hinged mounting and which arrangement affords an effective seal against the weather when the window sash is in closed position.

Another consideration of importance is the provision of mechanism that affords a tongue and groove construction at one side of the window sash and frame which may be operated to withdraw the tongue from the groove to permit of swinging movement on the part of the window sash. This mechanism constitutes for all effective purposes'a latching or lockin' device which-normall. maintains the win ow sash in slidable position in the frame, but which may be operated when it is desired to swing the sash inwardly to provide access to the exterior surface thereof.

A somewhat more detailed but nevertheless imp'ortant'feature of the invention is associated with the provision of hinge and latch co devices for each of the window sashes, which devices may be operated under all conditions regardless of the position of the sashes in the frame. More particularly, it is my idea to render both the u per and lower sashes swingable inwardly f r any position which they may assume in the frame, that is, the lower frame may be swung inwardly when in an upraised position, while the upper or outer sash may be swung inwardly while in a lowered position.

Other more detailed objects and advantages of the invention are associated with the provision of properly operable hin e and latch devices together with the mountmg of these devices in the sash and frame constructions. These will in part become apparent and in partbe hereinafter stated as the description of the invention proceeds.

For a full and more complete understanding of the invention, reference may be had to the following description and accompanying drawings wherein Figure 1 is a view in front elevation of. a window construction embodying the improvements of this invention;

Fig. 7 is a fragmentary plan-view taken at one end of the window frame.

Referring now to the drawings, a window frame of conventional design is shown in Fig. 1 and designated generally A. This frame A may be of any preferred construction which provides the structure necessary for the operation of the sashes therein. In this connection it is notable that the invention is herein described as being incorporated with a frame and sash arrangement made from wood, but the invention is not intended to be limited in this respect, as it is just as susceptible of bein employed in conjunction with metallic window constructions.

Operatively mounted in the frame A in a manner to be hereinafter described in detail are lower and upper sashes B and C which are intended to have sliding and swinging movements in accordance with this invention.

The frame A comprises a top piece shown at 10 which is connected to a bottom piece or sill designated 11 by side or frame members 12 and 13. The connections between these parts 10, 11, 12, and 13 may be of any suitable design and in the present instance are shown as consisting of miters 14. Carried by the top piece 10 are a pair of spring devices referred to generally as 15 and 16 which constitute a means for counterbalancing the weights of the sashes B and C, the spring device 15 being operatively associated' with the sash B, while the device 16 is connected up with the sash C. It is to be clearly understood that while the sashes are herein shown as being counterbalanced by the spring arrangements, the invention is not to be specifically identified with these spring arrangements, as the invention could well be availed of in conjunction with the old well-known weight arrangements already employed for the purpose of counterbalancing the window sashes.

The spring devices 15 and 16 are of duplicate construction, so only one of them is described for the purposes of this specification. Referring now more particularly'to Figs. 1 and 7, it is noted that a bracket 17 is secured to the upper surface of the top piece 10 in any suitable manner, such as by screws designated 18. This bracket 17 has up-turned ends 19 and 20 which are provided with openings 21. A shaft 22 extends through shaft. A cord indicated at 25 is taken up on the drum 23 and extends downwardly to the lower construction of the frame where it. is connected with the sash B in a manner to be later specified. This cord 25 finds its counterpart ina spring device 16 in the form of the cord 26 which is also wound on its wind-' ing drum and'passes downwardly to the sash C. A helical spring 27 is coiled about the shaft 22 and has one end anchored to the shaft as shown at 28, while its other end is a made fast to the bracket 17, as indicated at 29.

Referring now with more particularity to the construction of the side portions of the frame A, it is noted that the side frame 13 includes a side piece 30 which has parallel front and back faces 31 and 32, a side face 33 perpendicular thereto and an irregular generally inclined surface between the front and back faces 31 and 32 and which surface faces inwardly of the window frame. Referring now more particularly to Figs. 3 and 6, it is noted that this irregular inclined portion includes a groove 34 adjacent the front face 31 which groove is designed to accommodate the central portion of a hinge as will be later described. A narrow plane face 35 connects the groove 34 with a cutaway portion 36 that has centrally formed therein a circular groove 37 coextensive with the side piece 30. In fact, all of the grooves, surfaces, and cutaways now being described extendthe full length of the side piece. At its other side the cutaway 36 is spaced from a face 38 that is parallel to the front and back faces 31 and 32 by a narrow surface 39. Adjacent the free edge of the face 38 a groove 40 is formed which corresponds to the groove 34 in that it accommodates the central portions of the hinges of the upper sash member C. A narrow strip 41 connects the groove 40 with a cutaway 42 which is also formed with a circular groove 43 centrally thereof. The other edge ofthe cutaway 42 is spaced from the edge of the rear face 32 by a narrow strip 44. A back piece 45 may be secured to the side piece 30 over the face 32 to provide a projecting flange surface 46 which constitutes a guide for the sash C, as will be later described. A front piece 47 may be included in the construction of the side frame 13 and this piece partially extends over the tubular portion 50 which constitutes a lining for the circular groove 37. At the lower end of the side frame and coextensive with operates with the sash B, as will be later described to provide a good protective seal against weather conditions. A second metallic linin for the cutaway 42 and groove 43 isprovi ed and this is a substantial duplicate of that already described, havingthe side flanges 52 and 53 which are spaced apart by a groove 54 and which lie flush ith the strips 41 and 44. These side flanges and 53 are connected by a tubular portion 55 that lines the groove 43. In connection with this guide, the side flange 53 is provided at its upper portion with an out-turned flange 56 that is coextensive with the upper sash O and cooperates therewith as a weather strip to aflord protection. against the weather.

Referring now to the construction of the side frame 12 at the other side of the window it is noted that this frame includes a side piece 58 that extends the whole length of the window. This piece 58 has parallel front and rear faces 59 and 60 which are connected at one side by a side face 61 perpendicular thereto and at the other by an irregular series of inclined surfaces now. to be described. These comprise a short inclined face 62 ad 'jacent the edge of the front face 59 which is connected with a similar narrow inclined face 63 by a groove 64. Offset from this face 63 and connected thereto by a surface 65, parallel to the front and rear faces 59 and 60, is a narrow strip 66 which is connected are provided with metallic linings as shown at 71 and 72.

The sash B carries at one side a hinge and slide device adapted for cooperation with the tubular guide 57 and at its other side a movable tongue arrangement that cooperates with the guide 71. The sash B comprises a frame member having side pieces 73 and 74 and top and bottom pieces 75 and 76, respectively. These frame pieces 73, 74, 75 and 76 carry a pane of glass designated 77 which may be mounted therein in the well-known manner. The side piece 73 has an inclined face 78 designed to engage and lie fiat against the flat surface defined by the strips 35 and 36 and flanges 48 and 49. This inclined surface 78 is formed with a narrow groove 79 that is substantially perpendicular to the inclined face 78 and this groove 79 receives the weather strip 51 when the sash B is in closed or sliding position. The hinge part 80 is sunk in the face 78 so that its outer surface liesflush therewith and is securely fastened to the side piece 73 through the means of screws 81. A second hinge part 82 is connected to the side piece 73 1n a like manner and is spaced from the hinge part 80.

A gui e rod 83 is formed with curved portions 84that'extend through the .slot 57 and are integrally connected with hinge parts 85 and 86. The hinge parts 85 and 86 are connected with the hinge parts 80 and 82 in the usual manner, such as by pins 87 passing through the interfitting bored portions shown at 88. v The cord 25 which is taken up in the drum 23 extends downwardly into the tubular fguide 50 and is connected to the upper end 0 the ide rod 83 as shown at 89. It is evident t at the spring 27 ordinarily exerts an influence through the cord25 to offset the weight of the sash B and accompanying parts.

This sash B may be swung into position with the inclined face 78 engaging the flat surface previously mentioned and in which position the exterior face 90 of the sash engages the face 38 of the frame. In this position the-face 38 constitutes a guide, that cooperates with the'guide rod 83 and guide 50-to control the sliding action of the sash. When in this sliding position the weather strip 51 fits in the groove 79 in such manner as to admit of the sliding action on the part of the-sash. The sash may be swung outwardly, as shown in Fig. 6, to provide access to the exterior surface thereof, pivoting about the pins 87 during such swinging action. The bottom sill 11 may be provided with a weather strip, shown at 91, which projects u wardly and fits in a groove 92 formed in the ottom piece 76 of the sash.

Referring now more particularly to the mechanism carried by the side piece 74 of vthe s ash B, particular attention is directed to Figures 3, 4, and 5. The side piece 74 has inclinedsur faces 93 and 94 which are complemental to the inclined surfaces 62 and 63 on the side piece 58 and which are separated by a groove designated 95. Operatively mounted in the groove 95 is the mechanism which provides a locking guide which projects into the groove member 71 and which takes the form of a U-shaped channel member 96. This channel member 96 is positioned with its open face disposed inwardly of the. groove 95 and its curved nose 97 engaging with the tubular guide 71 when the sash is in normal sliding position. An up per link member 98 clearly shown in Fig. 5 is pivoted at 99 between the side walls of the channel member 96. At its other end the link member 98 is pivotally. connected as shown at 100 to a bracket member 101. This bracket member 101 has side walls 102 which are connected bv an end wall 103. The latter is formed with openings 104, while the side walls 102 are formed with over-turned flanges 105 which are also formed with screw openings (not shown). Fastening members in the form of screws pass through the openings in the side members 105 and the openings 104 to positively secure the bracket 101 to the side piece 74 of the sash B and in the groove 95. Spaced from' the upper link member 98 and adjacent the: lower end of the sash B a second link member 106 is pivotally mounted to the channel member 96 in the manner described with respect to the upper link 98 and as shown at 107. The other end of this link 106 is pivotally connected as shown at 108, to a second bracket member 109, this latter bracket being a substantial duplicate of the upper bracket meniber 101 and mounted in the groove 95 in the manner above described. These links 98 and 106 are always in parallel relationship and afiect the channel member 96 when the latter is moved either upwardly or downwardly to induce movement inwardly or outwardly of the groove 95, this being due to the toggle effects of these spaced links 98 and 106.

A coil spring 110 has one end anchored in the bottom of the groove 95, as shown at 111, and its other end is anchored between the walls of the channel member 96, as shown at 112. This spring 110 normally urges the channel guide 96 upwardly which tendency, in conjunction with the eifects of the links 98 and 106, urges the rounded nose 97 into the groove guide 71. It is evident that the channel member 96 may be moved downwardly under the influence of mechanism to be hereinafter described to cause retraction of the nose 97 from the groove 71. This downward movement on the part of the channel member 96 is provided for by the notched arrangement shown at 113 which insures proper pivoting movement of the link members 98 and 106.

The lower portion of the side piece 74 is cut away at 114 to accommodate the actuating mechanism for the channel member 96. This mechanism includes a pin 115 which is carried by the channel guide 96 adjacent its open edge and projects into the cutaway space 114. A cam member 116 is pivotally mounted, as shown at 117, in the side piece 74. This cam member 116 has a curved surface 118 which normally engages the pin 115, so that when the cam member is swung downwardly the 1 pin is moved downwardly and thereby draws the channel member 96 down. A stem 119 projects outwardly from the free extremity of the cam 116 and is notched as shown at 120 to accommodate a plate 121. This plate 121 closes the cutaway portion 114 and lies flush with the surface of the window sash. This plate 121 is provided with an arcuategroove 122 which receives the notched portion of the stem 119. This stem carries at its outer extremity an operating member in the form of a knob 123; This knob may be grasped by an and the channel member 96 downwardly to.

retract the rounded nose 97 from the oove 71.

The operation of the lower sash B may be briefly outlined as follows :W'hen the window is in sliding position, the nose 97 of the channel member 96 projects into the groove 71 and the weather strip 51 is received in the groove 79. The sash may be now raised or lowered in the customary manner. If it is desired to obtain access to the exterior surface of the sash, say for the purpose of washing the outer face of the window-pane 77, the knob 123 is grasped and swung over the plate defined by the arcuate slot 122. As previously pointed out, this operation closes the cam 116 to affect the pin 115 to cause downward movementof the channel member 96. This downward movement is controlled by the pivoted links 98 and 106 to cause retraction of the nose 97 from the groove. The window may now be swung outwardly into the desired position. sash B may be swung out even when the sash is in an upraised position with respect to the frame A as all the parts are designed to accommodate this movement.

The construction of the sash C- is a substantial duplicate of that already described. This sash is provided with a groove which is a counterpart of groove 79 in the sash B and which cooperates with the weather strip 56. The only appreciable distinction between the design of the sash G and sash B is that the plate 121 is countersunk below the surface of the side piece of this sash. In this instance the operating member 123 lies entirely beneath the plane of the front surface of the sash, this arrangement being availed of so as to prevent any interference between the sliding movements of the sashes B and C. The sash C slides under the guiding action of the guide rod in the tube 43 and the guiding effects of the projecting flange surface 46 of the member 45. It is notable that the sash C is of slightly narrower dimensions than the sash B and for this reason they both may be swung outwardly when superimposed one above the other.

The arrangement of springs providedin lieu of the usual counterweights is desirable in that it eliminates the need for having a comparatively large frame construction. When these springs are eliminated and counterweights employed. it is necessary that the side frames 12 and 13 be of sufficiently large dimensions to provide space in which the weights operate.

It is evident from the foregoing that I have provided a window which includes sashes It is evident that the which may be raised or lowered in the usual manner and each of which may be swung 'inwardly in any position. Also the various instrumentalities provided for effecting this action are of such design as to insure proper operation of the window sashes at all times.

While a preferred specific embodiment of the invention is hereinbefore set forth, it is to be understood that I am not to be limited to the exact constructions illustrated and described because various modifications of these details may be provided in putting the invention into practice within the purview of the appended claims.
