Patented Mar. 1, 1938 PATENT OFFICE AWNING TYPE WINDOW Tomlinson I. Moseley, San Francisco, Colin, assignor to Dalmo Sales Corporation, San Francisco, Calif., a corporation oi California Application April 29, 1935, Serial No. 18,726 5 Claims. (Cl. 189-67) This invention relates to improvements in multi-sash windows of the type comprising a plurality of adjustable sashes mounted one above the other in a window frame.

An object of this invention is to provide in a multiple sash window of the character described,

a simple, inexpensive, reliable and easily operable means for simultaneously opening and closing the several sashes through manipulation of one of the sashes, which means also provides for independent opening and closing of the said operating sash while other of the sashes are maintained in theopened position.

A further object of the invention is to provide an awning type window construction having a plurality of swinging sash mounted in the frame, together with connecting mechanism associated with said sashes for connecting the same together, said sash connecting mechanism being capable of operation automatically by manipulation of one sash to connect said sashes together for operation in unison, or to permit independent operation of said one sash.

A further object of the invention is to provide an awning type window construction embodying an operating mechanism designed to operate with a minimum of effort and to insure reliability and ease of operation, said operating means being capable of being readily and easily set up in a window frame and maintained in proper working condition while practically concealed from view.

In this specification and the annexed drawings, the invention is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such form, because it may be embodied in other forms; and it is also to, be understood that in and by the claims following the description, it is desired to cover the invention in whatsoever form it may be embodied.

In detail the construction illustrated in the drawings comprises a window frame l of rectangular shape, and formed of structural bar members of conventional or selected cross-section. The vertical side members of the frame l constitute jaxnbs and the inner face of each jamb is formed with a vertical channel 2 therein. A plurality of sashes designated 3, t and t are mounted in the frame so as to be swung into and out of a closed position in planar alignment with the frame, the operating mechanism for the said windows being confined in the channels of thejambs. The sashes are preferably made of bar sections which will complement and engage the' flanges of the frame bar sections to provide a relatively tight joint at the points of contact. The fixed bar sections ,6 and l are disposed transversely between the opposite jamb members of the frame between the bottom rail of the upper sash and the head rail of the middle sash and between the bottom rail of the middle sash and the head rail of the lower sash, thus when all of the sashes are in theclosed position, the top and bottom rails thereof will contact and engage 4 and rotatably confined. The shaft pivots extend in a horizontal plane in order that the sashes may swing in a vertical plane. 'Each shaft pivot 9 is provided with a channel-like slide shoe l0 thereon,'and the opposite vertical faces of said slide shoe have a taper which conforms to the section of the guide channels 2 in the jambs of the window frame. The slide shoes I 0 thus funcinto frictional engagement with the channel guides.

A travelling bar i2 is provided in each of the channel guides, and each travelling bar is fixedly connected to the vertically aligned slide shoes ill of the upper sash 3 and middle sash 4,

' thus tying said upper and middle sash together so that said sashes will move in unison at all times.

The lower end of each travelling bar extends down to a point opposite the side shoe ill on the lower sash i. The extreme lower end of the said of the slide shoe.

on the interior of each slide shoe ill of the lowertravelling bar has a socket or recess It provided in the side thereof facing the slide shoe, and the length of said socket is equal to that of the length of the slide shoe, in order that-the said slide shoe on the lower sash may rest in said socket. A shoulder or projection I4 is provided at the extreme lower end of the travelling bar, and a shoulder i is provided on the face of the bar by cutting out a portion thereof, the-said shoulder I! being spaced from the upper end of the socket I; by a distance equal to the length A projection I1 is provided most sash 5, which projections l'l are adapted to engage and ride upon cams i8 resting in the bed of the channel guide 2 for disengaging the slide shoes on said lowermost sash from the sockets in the travelling bars. 'When the slide shoes on the lowermost sash rest in the sockets in the travelling bars, then all three of the sashes will move together throughout all evolutionary movements. When the sashes are swung into a. selected open position and to a point where the slide shoes on the lowermost sash will register with the fixed cams it on the channel guides, then said lowermost sash will be disengaged from the said travelling bars. and said lowermost sash may be opened and closed independently of the upper sashes, both (I which would remain in the opened position. The lowermost sash may not be opened and closed independently of the upper sashes, when all of said sashes are in the closed position.

Each sash is connected with the frame by. a pair of fulcrum links ll. These fulcrum links are disposed on the outer opposite sides of the sashes and are concealed between the sashes and lambs when the sashes are closed. The fulcrum links are arranged on opposite sides of the sash and frame and in horizontal alignment. The

upper ends of the fulcrum links are pivotally connected to the sides of the sash at a point 22, intermediate the ends thereof. is on the lowermost sash are pivoted to a bracket 2| seatedin the bed of the channel guide 2. The fulcrum links I! on each of the uppermost sashes are elbowed or bent as at 2|, and the said bent end thereof projects out through a slot 22 in the face of the frame. said projecting end being pivotally secured at 23 to a'bracket 24 which extends out from the face of the frame I. By offsetting thelowermost pivotal connection of the fulcrum arms on the upper sashes, beyond the plane of the frame, the leverage necessary for opening a.

and closing the sashes isamplified to a point where the sashes may be opened and closed with The fulcrum links a minimum of effort. Likewise, the angularity of the fulcrum links on the uppermost sashes is.uti-

lized for creating a pressure upon the said sashes when in the closed position, and serves to hold the said sashes tightly closed and to eliminate opening movement actuated by wind pressure or the like. I

The windows operate as follows. Assuming all of the sash to be closed, the same are opened by pushing outwardly on the lower rail of the lowermost sash, which causes all of the sashes to open simultaneously. The opening movement will pro ceed to a point where the traveling bars will descend and bring the slide shoes on the lowermost sash into registry with the fixed cams i8- cient to bring the'lower end of the said traveling bars out of registry with the fixed cams on the lambs. Through the movements last described,

the lower sash will be closed and the upper sashes will remain open; When the lower sash is again swung into the opened position, the slide shoes thereon will immediately snap into engagement with the sockets l3 in the traveling bars when,-

ever and at such times as said slide shoes register with said sockets, the spring behind the pivot pin on said slide shoes urging the aforementioned parts into engagement. When the slide shoes of the lower sash. are reengaged with the traveling bars, then all of the sashes will operate in unison for any desired closing or opening movements. It will be noted thatthe slide shoes onthe lowermost sash when disengaged from the traveling bars, move in the guide channels 2 provided in the lambs, and do not depend in any respect upon the traveling bars for any guiding movement thereof.

It is obvious from the foregoing that by manipulation of the lowermost sash that. all of the sashes may be operated in unison or the bottom sash may be opened and closed independently of the upper sashes when the said upper sashes are in the opened position.

The flanges on the bar sections out of which the sashes and frame are formed, are so designed that the same-will contact snugly and tightly when inthe closed position and thus provide an eflective watertight joint for the most exacting of all weather conditions. Furthermore, the oil'- center placement of the fulcrum links in relation to the pivots of the sash, cause the flanges on the sash. bars to; be cinched tightly into engagement with the corresponding sections on the water-proofing. In my window construction, each of the plurality of sashes engages a fixed part of the frame around all four sides thereof when in the closed position, thus insuring that the entire surface of the window will be sealed against inclement weather conditions, dust, drafts and thelikep Having thus described this invention, what I claim and desire to secure by Letters Patentis:
