SWINGING WINDOW.

Application filed November 29, 1920. Serial No. 426,930.

T 0 a?! whom it may concern;

Be it known that I, HENRY T. ATKINSON, a citizen of the Ynited States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful Improvements in Swinging 'indows, of which the following is a specification.

This invention relates to swinging windows, and more particularly to the mounting and operating means therefor.

The object of the invention is to provide means as above characterized, whereby a number of superposed windows may be operated simultaneously from a single position.

It is also an object of the invention that the mounting and operating means shall be applicable for a single window as well as for a number of superposed windows.

It is likewise an object of the invention that the operating means will permit the window or windows to be positively held in any position desired.

It is a further object that the windows when in closed position will form an absolutely tight closure.

Other objects are: That the operating means shall be easily manipulated: and that the construction as a whole, for obtaining the different results above mentioned, will be simple and durable.

lVith the above and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts, to be hereinafter more fully described, claimed. and illustrated in the accompanying drawings, of which:

Fig. 1 is a front elevation of a. plurality of superposed windows illustrating the ap plication of my invention.

Fig. 2 is a vertical section on the line 2-2. of F i 1. with parts broken away to more clear y illustrate the invention, and also showing in dotted lines the windows when in open position.

Fig. 3 is a perspective view of the trunnion hinge.

1F ig. 4 is a fragmentary section substantially on the line -14 of Fig. 1.

Figs. 5 and 6 are detail views illustrating the adjusting or locking bar.

Fig. 7 is an enlarged fragmentary view of the upper window with parts broken away and in section to illustrate the invention.

Referring to the drawings more particularly, A indicates generally a window frame, consisting of the usual head and sill 11 and 12, respectively. and the jarnbs 13. In thewindow frame there are mounted for swinging movement the windows 11, 15 and 16. Between the two upper windows there is shown a transom sill 1 1', which is for reinforcing the frame. and also enhancing its general appearance. However the use or omission of the transom bar is optional. The transom may be of any thickness with outdefeating any of the objects of the present invention, and which will later become evident. r

' Tn carrying out the invention, the sides 13 of the frame are provided with a pair of grooves 17 for each window sash. In each groove there is secured a U-shaped guideway 18. which is adapted to slidingly accommodate the trunnion 19 of a trunnion-hinge 20. A pair of trunnion-hinges 20 are secured at the top of each window sash, one on each side as shown. Each trunnion-hinge 20 is also formed with a second trunnion 22, which is in axial alignment with the trunnion 19. Adjusting or locking bars 23 are provided for jambs 13-of the window frame A and each trunnion 22 on one side of the windows is journalled inthe adjusting bar 23, with which they are associated. The adjusting bars extend through the transom sill 14: and are free to move upward and downward with the trunnion-hinges 20. Each window is also provided with a pair of links 24, one of each pivotally connected at its outer end to the window sash thereof, as at 25,and pivotally connected at its inner end to the jamb of the window frame A, as at 26. The adjusting bars 23 slide or work over the pivotal connections 26 of the links 24..

Assuming that the sashes are in the 0sition as shown in dotted lines in Fig. 2. rom

the description now given it becomes obvious.

that if the lower end of any sash was drawn inwardly that itwould cause its trunnionhinges 20 to move upwardly in the guideways 18. This action would likewise move the adjusting bars upwardly, and in this manner all the sashes would be simultaneousl v closed. Opening of the sashes can, of course.be effected by merely pushing outwardly on the lower end of one of them. It may here be observed that the mounting it ,A

of the sashes is such that all are in perfect balance at any position with respect to opening and closing, and that they will remain stationary at any open position when any force against them ceases.

In order that there shall be an absolutely sash portions of the sashes are parallel to the slope of the sills; the urpose being to permit the window to orm a tight closure. The head 11 and likewise the transom bar 14' are each provided with a downwardly extending flange portion 30. The two upper windows when being closed freely enter on the inner side of these flanges as shown in Fig. 2. The flanges not only aid the windows in making a tight closure, but also brace the same to some extent.

The inner side of the sashes, when closed, abuts a strip 32. One purpose of the jamb strips is to cover the adjusting bars and associated parts and also afford a recess into which the links 24 may be brought when the windows are closed; said recess bein between the inner side of thestrips an the frame as at 33, Fig. 4. Each jamb strip is provided with a longitudinal groove 34 adapted in shape to accommodate the bar 23 and extending portion of trunnions 22. The strips also form an abutment for the sashes. The sashes also are provided with 1i 5 35, which are adapted to seat upon a le ge 36 formed in each jamb 13 of the Window frame. This forms the first weather'closure for the window opening, another being the strips 32 as before described.

For locking the windows in any open position, a guide member 38 is provided for the lower end of one or both of the ad'usting bars 23, preferably the one on the le t hand side of the frame. This guide is of course covered by the strip 32 and secured in position by screws or the like-as shown in Fig. 5. The intermediate portion of the strip 32 is provided with a threaded opening adapted to receive set screw 39. said set screw extending through an opening in the member 38 and having a knurled head 40 by which it maybe manipulated.

As is obvious by loosening and tightening this set screw, the adjusting bar 23 may be held in any position desired and thus the windows may be likewise held in any desired position. A similar arrangement could be made for the other adjusting bar. Guides, similar to 38, can however be provided for the other adjusting bar if so desired.

For locking the windows in closed position any desirable latch look, as at 41, may be used for the lower'windows, the upper window, however, should have a catch which will permit opening and closing without any manual manipulation as the spring and blade type indicated at 42.

From the foregoing description taken in connection with the manner of operation of the present invention already given, it is believed that the construction, operat-on and the mounting of and the operating means for the windows can be clearly understood. It may be'here noted that the windows may be opened or closed with only a slight exertion on the part of the operator, and at no time is the operatin means subject to getting out of order. It a so may be noted that the operating and mounting means shown may be used in conjunction with operating the two lower windows alone, the upper window being operated individually, or may be used to 0 rate the lower window and the upper win ow, leaving the middle window to be operated individuall Likewise, the same mounting means an operating means may be used to operate a single window with equal efliciency. It should also be noted that the position of the trunnion-hinges with relation to each sash permits the set of the supporting links thereof to be considerably above the longitudinal center of the sash, thereby causing eas movement of the swinging of the sash; an it is to be noted further that the links assist materially in stabilizing the balancing of the sashes in any position that they may be placed.

In the present description given two adjusting bars 23 are shown. It is to be understood however that one adjusting bar could be used if so desired. Also, in the present description it has been stated that the windows are operated b drawing in- Wardly or pushing outward y on one of them. It is to be understood however that the same operation could be accomplished by means of a handle or the like suitably connected with the adjustin bar.

While I have shown t e preferred form of my invention as now known to me, it will be understood that various changes in the combination, construction and arrangement of parts might be made by those skilled in.

the art, wit out departing from the spirit of the invention, as claimed.
