WINDOW Arthur B. Chapman, Oshkosh, Wis.,
Company of Wisconsin, of Wisconsin assignor to Morgan Oshkosh, Wis., a corporation This invention relates to window constructions and is more particularly concerned with improvements in casement or awning type windows which are adapted to be hinged at one edge and to swing outwardly from the window frame.
It is a general object of the invention to provide in a window construction of the type having a sash member which is adapted to be hinged into and out of an angled or tilted position relative to the frame, a supporting mechanism for the sash which is of simple and rugged construction, which will rigidly support the sash in any position of adjustment, which will pull the sash, when closed, into tight engagement with the surrounding frame and which may be readily and easily manipulated or operated to move the sash to and from its open and closed positions.
It is a more specific object of the invention to provide a mechanism for supporting a sash of the casement or awning type within a supporting frame wherein the sash mounted on pivots which are arranged adjacent opposite coruers of the sash and which are movable relative to the supporting frame whereby the sash is positioned, when fully opened, with opposite side edges a sufficient distance away from the corresponding side edges of the supporting frame to permit the outside surface of the sash to be readily cleaned from the inside of the supporting frame.
It is another object of the invention to provide a mechanism for supporting and operating a hinged sash which will rigidly hold the sash relative to its supporting frame in any of the open positions to which the sash may be adjusted and which will force the sash into tightly sealed engagement with its supporting frame when the sash is moved to a fully closed position.
it is a further object of the invention to provide a mechanism for mounting a sash in hinged relation in a supporting frame which mechanism is adapted to connect the sash to the frame at oppositely disposed sides of the sash and which mechanism is operated by a single operating member.
It is another object of the invention to provide a mechanism of the type described which will rigidly support the sash iin any position relative to the supporting frame, and which, when the sash is moved to the closed position, will first tightly draw the sash against the frame throughout the periphery of the sash and then lock the sash in tight engagement with the frame thereby preventing any accidental release of the sash.
It is another object of the invention to provide a supporting and operating mechanism for a swinging sash which includes carrier members mounted for movement toward and from each other and pivot means connecting the sash to the carrier members whereby movement of the carrier members operates to open and close the sash relative to its supporting frame and continued movement of the carrier members, in the direction to close the sash, after the sash has been brought into engagement and seated in its supporting frame, will operate States Patent Zflhhfil Patented May 311, 1955 to lock the sash in its closed position while reverse movement of the carrier members will first unlock the sash and thereafter swing the sash into an open position.
It is a further object of the invention to provide a window having a sash member mounted in a supporting frame in which the sash member is pivoted on an axis extending transversely of the opening in the supporting frame by movement of an elongate operating link or brace member having pivotal connections at its opposite ends with the sash member and with the supporting frame, and in which the movement of the operating link member is controlled so that the pull on the sash member continues as the sash member approaches the closed position and the final movement of the link member draws the sash member into tightly closed engagement with the supporting frame.
It is another object of the invention to provide a window having a sash member pivotally mounted in a supporting frame for swinging movement about an axis extending transversely of the sash member, an operating link which is pivotally connected at one end to the sash member and slidably and pivotally connected at its other end to the supporting frame, and mechanism for controlling the sliding movement of the end of the operating link relative to the frame, which mechanism includes a movable guide member which is arranged in sliding engagement with the operating link, intermediate the ends of the same, and which is moved to exert a force on the link in the direction to swing the sash member into closed position, as the guide member moves toward the end of the link which is connected to the sash mem her, during the closing movement of the sash member.
It is a further object of the invention to provide in an awning type window having a generally rectangular supporting frame and a sash mounted therein, mechanism for swingably supporting the sash which is arranged between the side edge of the sash and the adjacent frame member, which mechanism comprises a guideway formation ex tending along the frame member and a pair of slide plates mounted for relative movement in the guideway formation, pivot members at opposite ends of the slide plates, and a device for moving the slide plates to adjustably position the pivot members relative to each other and to the supporting frame, the sash being connected adjacent one of its corners to one of the pivot members whereby it is adapted to swing about an axis extending parallel to one of its edges with the axis being movable relative to the supporting frame upon movement of the slide plates, an elongate operating link member extending between the other pivot member and a pivot point on the edge of the sash which is spaced from the pivot member about which the sash swings, and a guide member for controlling the movement of the link member which guide member is mounted on the slide plate which carries the pivot on which the sash swings whereby when the slide plates are moved to carry the pivot members thereon in opposite directions the operating link is swung relative to the frame about the guide member as a fulcrum to exert a pull on the sash in the direction to close the same and seat it in tight engagement with the frame.
It is still another object of the invention to provide an operating mechanism which may be incorporated in a window having a plurality of sash members swingably mounted in a suppoiting frame, with the mechanism so arranged that all the sash members may be moved simultaneously either to open or closed position by the operation of a single control member, and when the control member is moved in the direction to close the sash members each sash member will be pulled into tight engagement with the supporting frame and the adjoining sash members and securely locked therein, the mechanism being operative upon movement of the control member in the opposite direction to unlock each sash member and thereafter to move the same to the open position.
These and other object and advantages of the invention will be apparent from a consideration of the mechanism which is shown by way of illustration in the accompanying drawings, wherein:

Referring first to Figs. 1 to 11 of the drawings there is illustrated a window in which a single sash unit is mounted in hinged relation in a supporting frame by means of a combined supporting and operating mechanism having incorporated therein the principal features of the invention.
The illustrated window comprises a generally rectangular sash 10 and a supporting frame 11 which-provides the opening within which the sash 10 is adaptedto be positioned as a closure member. The frame 11 comprises opposite side or end members 12 and 13, a top member 14 and a bottom sill 15, all of which may be formed of metal, wood or any other suitable material.
nisms. Only one of the mechanisms 23, 23 will be described in detail.
The mechanism 23 comprises an elongate supporting plate member having its opposite side edges reversely bent or inturned to form a base portion 30 and oppositely disposed side flanges 28 and 29 which are spaced from the base portion 30 and form therewith a guideway 31 which is generally C-shaped in cross section. An axially extendingoperating shaft or rod 32 is arranged above the base 30 and supported at opposite ends of the mechanism 23 by transversely extending bearing members 33 and 34, which end bearing members 33 and 34 extend in bridging relation between the side flange members 28 and 29. The shaft 32 is divided into two sections 35 and 36 and the opposite ends are threaded, with the pitch of the threads in opposite directions. A transversely extending bearing formation 37 is arranged in spaced relation to the base plate 30, approximately in the center of the mechanism 23, which extends in bridging relation between the side flanges 28 and 29. The bearing 37 forms a support for the center section of the operating shaft 32. The shaft 32 is provided with fixed collars, or sections of enlarged diameter 38 and 39, which collars 38 and 39 are provided with peripheral grooves 40 and 41. The grooves 40 and 41 receive bifurcated bracket members 42 and 43, which bracket members are secured on and extend upwardly of the base 44 of the center bearing member 37. The legs of the fixed bracket members '42 and 43 engage in the grooves 40 and 41 and prevent the operating shaft or screw 32 from moving in the axial direction while permitting it to rotate about its longitudinal axis.
The operating shaft 32 is provided at its lower end with a bevel pinion 45 adjacent the bearing member 33 which pinion 45 is in engagement with a pinion 46 mounted on a cross shaft 47 extending between the laterally spaced bearings 48 and 49 which project outwardly of the base plate 30. The cross shaft 47 extends to the inner side of the frame and its inner end is formed into an operating handle 50, which may have a detachable connection therewith, if desired. Rotation of the handle 50, of course, operates the shaft 32 in either clockwise or counterclockwise direction, as desired.
The upper threaded section 36 of the shaft 32 carries in threaded engagement thereon a movable slide block member 51 which is attached to the upper end of a relatively narrow elongate plate member 52. The plate member 52 is received in sliding relation in the guideway 31 formed between the flanges 23 and 29 and the base plate 30, the width of the plate member 52 being approximately half the width of the guideway 31. The lower threaded end portion 35 of the shaft 32 carries thereon in threaded engagement therewith, a slide block When the frame 11 is formed of wood, the sill member I 15, is preferably provided with a metal Weatherstrip 16 and suitable Weatherstripping 17, 18 and 19 is also pro vided on the side frame members 12, 13 and the top frame member 14, respectively. The top frame member 14 is recessed or shaped at 20 (Fig. 4) to receive the top cross rail 21 of the sash member 10. The side or end members 12 and 13 of the frame 11 are recessed at 21 and 22 (Fig. 6) to receive sash supporting and operating mechanisms 23 and 23. The sash side frame member 24 and 25 are also recessed, at 26 and 27, to accommodate the members which connect the same to the mechanisms 23 and 23.
The sash supporting and operating mechanisms 23 and 23 are arranged on opposite sides of the sash 10 and are substantially the same, differing, however, in that they are right and left hand and there is a connecting mechanism for simultaneously operating the two mechamember 53 which is secured to the lower end of an elongate slide plate member 54 which is approximately the same width as slide plate 52 and which is also received in sliding relation in the guideway forming recess 31.
The slide plates 52 and 54 are arranged in edge engaging sliding relation in the guideway 31 and move in opposite directions, with the slide blocks 51 and 53, when the operating shaft 32 is rotated in either direction.
The upper side block 51 is provided with a curved or angled plate 55 which is secured to the block 51 and extends laterally and in parallel relation with the side edge of the base plate 30, along and slightly spaced from the outer edgeof the outer flange 29 thereof. The bracket plate 55 is provided with an elongate slot 56 which extends in outwardly spaced relation to and in the lengthwise direction of the flange 29. The slot 56 receives a pivot pin 57 projecting from the side member 24 adjacent the top rail 21 of the sash 10. The pivot pin 57 provides an axis for swinging movement of the sash 10 which extends crosswise of the frame 11 in generally parallel relation to the top frame member 14 and which is movable away from the top frame member 14 by movement of the slide block 51 toward the center of the supporting mechanism 23, with the slot 56 providing for predetermined movement of the slide block 51 relative to the pivot pin 57, at a time and for a purpose which will be described.
The bottom slide block 53 is connected by pivot 58, extending from an adjoining portion of the slide plate 54, with one end of a supporting and actuating bar or plate member 60 which constitutes a connecting arm extending between the side edge of the sash 10 and the mechanism 23. The elongate arm or bar 60 is connected at its opposite end to a pivot 61 which extends laterally of the side edge of the sash 10. The pivot 61 and the pivot 57 which is spaced a substantial distance therefrom may be conveniently mounted on an elongate supporting bar or plate 62 which is positioned in the recess 26 and attached by screws or other fastening elements to the side frame member 24 of the sash 10. The supporting arm 60 is provided with an axially extending slot 63 in the end which receives the pivot pin 61 and the plate 62 is provided with a guide slot having a curved portion 64 and a straight portion 65, with the latter extending in the longitudinal direction of the side edge of the sash 10, for receiving a guide pin 66 which projects from the face of the arm member 60 at a predetermined axial distance from the elongate slot 63. The arrangement of the pivot pin 61, the pivot slot 63, the guide slot 6465 and the guide pin 66 is such, that, when the arm 60 is at an angle to the bar 62, as in Fig. 3, the pin 61 rides in the inner portion of the pivot slot 63 and is prevented from moving in the slot 63 by engagement of the guide pin 66 in the curved guide slot 64. When the arm 60 and the plate 62 are moved to parallel or axial alignment, the guide pin 66 is free to move into the straight portion 65 of the guide slot on the bar 62 and permit the pivot pin 61 to move up to the top or outer end of the pivot slot 63. This arrangement provides for relative movement between the pivot pins 61 and 57, which are fixed on the edge of the sash 10, and the ends of the supporting bracket plate 55 and arm 6%, when the sash is in closed position and substantially parallel to the operating shaft 32 of the mechanism 23, as in Figs. 4 and 5. Thus the bracket plate 55 and arm 60 have a limited movement, relative to each other and relative to the sash 10, when the sash is in the fully closed position (Figs. 4 and to lock and unlock the sash in a manner which will be de scribed.
The supporting arm 60 is provided at the end adjacent the slide block 53 with a curved edge formation 67 on the outer edge which terminates adjacent the center of the arm 60 at an axially and inwardly extending recess or slot 68. The slot 68 is adapted to receive a latch pin 69 projecting outwardly of the plate member 62 on the edge of the sash when the sash 10 is in the closed position in the frame 11 (Fig. 4) with the plate member 62 and the adjoining portion of the arm 60 in generally parallel overlapping relation.
The movement of the arm 60 is controlled by a small reversely bent flange member 70 which is secured to the free end 71 of the slide plate 52 and which projects outwardly over the flange member 29. The flange member 70 is slotted at 72 in the plane of the arm member 69 and the curved edge 67 of the arm 60 rides in the slot '72 as the arm 60 moves about the pivot 53, the flange member 70 forming a guide for the operating arm or link 60 and limiting its movement about the pivot 58. As the slide block 53 is moved toward the lower end of the operating shaft 32 the pivot 58 causes the arm 60 to swing inwardly and move the sash 16 toward the closed position. The slide block 53 and slide plate 52 are moved in the opposite direction and the guide member 70 moves along the curved edge 67 of the arm 60 toward the slot 68 thereby forcing the arm 60 in the counterclockwise direction about the pivot 58 which in turn forces the sash toward the pivot bracket and holds the pivot member 57 in the upper or outer end of the slot 56. This results in the sash 10 being properly seated in the opening in the frame 11 when it is drawn, by rotation of shaft 32 and the resulting movement of the operating arm 60, under control of the guide member 70, to the closed position shown in Fig. 5. After the sash 10 is drawn to the closed position, rotation of the shaft 32 is continued and the slide blocks 51 and 53 move to their final position. The block 53 carries the operating arm downwardly and engages the locking pin 69 in the slot 68 while the guide member is moved upwardly and engages the straight edge 75 of the slot 68, forcing the arm 60 in the direction away from the sash 10 and locking the arm against further movement. The engagement of the pin 69 in the slot 68 and the camming action of the guide 70 on the edge 75 of the slot 68 provides a positive lock for the sash which can be disengaged only by rotating the shaft 32 in the opposite direction for opening movement of the sash.
The operating mechanism 23 at the opposite end of the sash 10 is connected for operation with the mechanism 23 by a cross connecting rod 76 (Fig. 6) which is provided at its one end with a bevel pinion 77 (Fig. 11) engageable with the bevel pinion 46 on the shaft 47 so that it is rotated upon rotation of the operating handle 50. A pinion 78 on the other end of the rod 76 engages with the end pinion on the bottom end of the operating shaft for the mechanism 23'. The connecting rod 76 may be separably connected at 79 and 80 to the pinion 77 and 78 so that the mechanisms 23 and 23' may be disconnected, when desired. The connecting rod 76, may, of course, be housed in a suitable covered recess 81 in the bottom frame or sill member 15.
in order to limit the extent of the movement of the operating handle 50 and avoid stripping the threads on the shaft 32 the handle shaft 47 is threaded and carries a nut 82 (Figs. 11 and 12) which is held against rotation by engaging in a guideway 83 in an angled exten sion or arm 84 on the bearing member 48. The stop nut 82 engages against the bearing member 48 at one end of its movement and against the face of the bevel pinion 46 at the other end of its movement to limit the rotation of the shaft 47. Any other stop means may be employed in the mechanism to indicate the limit of movement of the rotatable elements or to provide a stop for the same and prevent damage to the mechanism in the event the operator attempts to turn the handle 50 too far in either direction.
The recesses in which the mechanisms 23 and 23' are housed may be extended as required to accommodate the movement of the members. The flange 29 is cut away at 85 (Fig. 3) to provide clearance for the projecting portion 36 of the plate member 62 when the sash 10 is closed.
The invention may be embodied, with some modifications, in a multiple sash window as illustrated in Figs. 13 to 15. In this form of the invention three sash units 110, 210 and 310 are mounted for swinging movement in a single opening provided in the frame 111. The lower sash unit may be identical with sash unit 10 while the middle sash unit 210 is recessed or grooved on its lower edge 220 to form a rabbet joint with the upper edge 121 of the lower sash unit 110 when the sash are in closed position. The upper sash unit 319 is likewise rabbeted on the lower edge at 320 to form a joint with the rabbeted upper edge 221 of the middle sash 216. The vertical side members 112, 113 and the horizontal top and bottom members 114 and 115 of the frame 111 may be identical with the corresponding members of frame 11, except for the length or height of the side members.
The sash units 110, 210 and 310 are supported for swinging movement in the frame 111 by mechanisms 123 arranged on opposite sides of the frame 111, the mechanisms being arranged in suitable recesses between the inner faces of the vertical frame members and the adjacent side edges of the sash units 110, 210 and 310. Only one of the supporting mechanisms 123 is illustrated (Figs. 14 and 15) the other supporting mechanism being at the opposite side of the frame 111. These mechanisms are arranged in the same relation to each other as the supporting mechanisms 23 and 23 in the single sash window and are provided with the same kind of a bottom connecting rod mechanism so that they may be operated simultaneously by a single control handle 150.
The operating mechanism 123 is constructed so that the lower portion thereof corresponds to the mechanism 23 with the guideway forming base member and the cooperating inturned flange formations 128 and 129 being extended to the top frame member 115. An operating shaft 132 is mounted at the lower end of the base member 130 which is identical with the shaft 32 and extends the height of the bottom sash unit 110. The shaft 132 carries in screw threaded relation thereon the upper and lower slide blocks 151 and 153 which have attached to their bottom or inner faces the slide plates 152 and 154. The lower ends of the slide plates 152 and 154 are identical with the slide plates 52 and 54 but the upper ends thereof are extended toward the c top frame member 114 as shown. The extended upper ends of the slide plates 152 and 154 are seated in edge engaging sliding relation in the guideway 131 formed by the extended upper portions of base member 130 and cooperating flanges 128 and 129, and carry thereon the members for opening and closing the upper sash units 210 and 310.
The lower sash 110 is connected to the bracket 155 which extends from the slide block 151 on the slide plate 152 and is slotted at 156 to receive the pivot 157 on the sash edge. An operating arm member 160 has one end slotted at 163 to receive the pivot 161 on the side edge of the sash 110 and the other end connected by pivot 158 to the slide plate 154. A slottedguide member extends from the lower end of the slide plate 152 and engages in guiding relation with the outer edge of the arm member 160. The details of the connecting members between the sash 110 and the operating mechanism 123 which are not described herewith are the same as in the corresponding members in the form of the invention illustrated in Figs. 1 to 11, and the operation of the mechanism 123 to control the movements of the sash 110 is the same as the operation of mechanisms 23, 23' to control the sash 10.
The middle sash 21!) (Figs. 14 and 15) is mounted for swinging movement relative to the frame 111 by a pivotal connection with bracket member 255 which extends from a slide block 251 mounted on the slide plate 152 and is slotted at 1.56 to receive the pivot pin 257 on the sash 210. This sash is operated by the movement of the arm member 260 which has one end slotted at 263 to receive the pivot 261 on the side edge of the sash 210 and the other end pivotally connected at 258 to the slide plate 152. A slotted guide member 270 extends from the slide plate 152 and engages with the outer edge of the arm member 260 and guides or limits the movement of the arm member 260, in the same manner as the guide member 70 affects the movement of the operating arm 60, when the slide plates 152 and 154 are moved relative to each other by rotation of the operating shaft 132. In the closed position of the sash 210 (Fig. 15) the guide member 270 moves into the slot 268 in the arm 260 and cooperates with the locking pin 269 on the sash edge which is also received in the slot 268 to hold the arm 260 and sash 210 in closed and locked relation to the frame 111.
The upper sash 310 is connected by the pivot 357 with the bracket 355 which receives the pivot pin 357 in an elongate slot 356. The bracket extends from a slide block 351 mounted on the end of slide plate 152.
This sash is operated by the arm member 360 which has an elongate slot 363 at the outer end for receiving the pivot pin 361 which extends from the side edge of the sash 310. The arm member 360 is connected at its other end by pivot 358 with the slide plate 154 adjacent the upper end of the latter. A slotted guide member 370 extends from the slide plate 152 and engages the outer edge of the arm member 360 to guide and limit the pivotal movement of the same as the slide plates 152 and 154 are moved relative to each other by rotation of the operating shaft 132. The arm member 360 is slotted at 368 to receive the guide member 370 and the locking pin 369, the latter extending from the side edge of the sash 310, when the sash 310 and the operating arm 360 are moved into the final closed and locked position relative to the frame 111.
The operation of the multiple unit window is the same as the operation of the single unit window. By rotating the handle 150 in one direction the operating mechanism is actuated to move the slide blocks 151 and 153 toward each other which in turn moves the slide plates 152 and 154 in the direction to move the hinge pivots 157, 257 and 357 toward the operating arm pivots 158, 258 and 358, respectively, and thereby force the sash pivots 161, 261, and 361 outwardly to swing the sash 110, 210 and 310 simultaneously to the open position. Reverse rotation of the handle 150 carries the slide plates 152 and 154 in the oppositedirection and pulls the sash pivots 161, 261 and 361 toward the frame 111 with the guide members 170, 270 and 370 forcing the operating arms 160, 260 and 360 in the counterclockwise direction about their moving pivots 158, 258 and 358, respectively, to draw the end margins of the sash units 110, 210 and 310 tight against the vertical side frame members112 and 113 and upon final movement of the slide plat s 152 and 154 to engage the locking pins 169, 269 and 369 in the respective locking slots 168, 268 and 368 in the operating arms 160, 260 and 360 thereby securely locking all of the sash units in closed position in the frame. The details of the mechanism employed in the multiple sash window which have not been specifically described are the same as the corresponding details in the single sash window illustrated in Figs. 1 to 12 and operate in the same manner.
In both forms of the invention which have been illustrated awning type windows have been shown in which the sash unit hinges or swings about a horizontal axis adjacent one edge of the same. The mechanism is equally applicable to a window of the easement type in which the sash unit swings about a vertical axis. The relative size, shape and direction of swing of the individual sash units may, of course, be varied as desired.
While specificdetails of construction and particular materials. are'referred to in describing the illustrated forms of the invention'it will be understood that other details of construction and other materials may be resorted to within the spirit of the invention.
