It has long been a problem in awning type and casea ment windows to provide efficient, durable and yet inexpensive hardware for supporting and operating the individual sash members while at the same time permitting satisfactory screening of the windows.

It is an object of my present invention to provide novel and improved hardware for supporting and operating an awning type window and adapted to carry and permit easy operation of the individual sash of'said window, while permitting use of a stationary screen across the inside of the entire window.

It is another object to provide supporting and operating hardware particularly adapted to cooperate with my overlapped awning type window construction, disclosed in my above identified co-pending application, topermit individual and independent operation-of each sash of the window. 1

More specifically it is an, object to provide sash supporting hardware adapted to be mounted on the upright members of a window frame on each side of a sash,

and including a pair of pivotally interconnected toggle ware adapted to be connected to one of the toggle arms of the supporting hardware, and including a link with a bell-crank lever arrangement for controllably positioning said toggle arm and the sash connected thereto.

It is still another object to provide a worm and pinion operating mechanism adapted to controllably vary .the position of each individual window sash and having a retractable operating handle.

These and other objects and advantages of my invention will more fully appear from the following description made in connection with the accompanying drawings wherein like reference characters refer to the same or similar parts throughout the several views, and in which; 7 r v Fig. l is an outside elevational view of three of my awning type sash, mounted in a single frame to form a single window unit for a building;

As illustrated in the" accompanying drawings, I pro-.

vide a window unit in the form of a plurality of awning type sash mounted in a casing or frame, which is in stalled in a building. A fragmentary portion of a building side-wall is best shown in Figs. 1 and 2, and is desig nated as anfentiretyby. the numeral 17. The outer wallf 17 is covered'with shingles which have a relatively narg row overlappresenting a very wide, visible portion of the shingle, as best shown in Fig." 1. The frame or cas-' ing' 18 is securely fixed in the wall 17, and suitable molding trim-surrounds the same on the outside as well as the inside. The trim' on the outside is designated by the numeral 181;, and the trimormolding on'theinside is designatedbylthenumeral 18b. Each .sash is desig The sash supportinghardwareunits designated as an entirety by the letter} H, andillus'trated in Figs; 113,514 and l5,'consist in an elongated mounting strip 19, having the cross-sectional shapeshownin] Fig. lit/forming a track 19a -A slide 20 is mounted in the'trac k 191:, as best shown in Fig. 15, and is free to slide up and down therein with provision for frictionally retaining the same in any set position. A sash supporting toggle arm 21 has its upper end pivotally connected to slide 20 as by pivot pin 22, and a bracing toggle arm 23 has its uppercnd pivotally connected at the lower portion of supporting arm 21 as by the pivot pin 24, and its lower end pivotally" connected at the lower portion of mountingmember 19 by thepivot pin 25. In the form of the invention shown,

threewindow sash S areprovided and thefside stiles 16c and 16d are respectively mounted on the sash supporting toggle arms 21 of a pair of supporting hardware units H which arms above described are respectively recessed into'said stiles, with the upper ends of the stiles adjacent the upper ends of the supporting arms 21 and slides 20. The mounting member 19 is securely attached to the upstanding member of frame 18 as by driving screws into said frame'throughthe apertures 19b provided'in mounting member 19. ".In closed positionthe each other, as well as being substantially aligned with the mounting strip 19. The mounting strip is disposed at a slight inclination on the side frame members, as

best shown in Fig. 3, and the window sash are also sloped at a similar inclination when in closed position.

In the form shown, the side stiles 16c and 16d of the sash S are completely concealed from the inside and a bumper strip 26 is secured to the side portions of frame 18. The bumper edge of said strip is inclined to engage the inner marginal edge portion of the stiles 16c and 1611 when the sash are in closed position, and a slot is provided between the bumper strip 26 and the adjacent portion of frame 18 on each side of each of the-sash members to permit installation of the operating and locking hardware. In Figs. 4 and 5, one form of operating hardware is illustrated and is designated by-the letter A. In form A a link 27 is pivotally connected by a removable pin 28 to the bracing toggle arm 23 at a point disposed in slightly spaced relation above the pivot 25. An oscillatable actuating member which, in this form of my invention, consists in a bell crank 29 is pivoted on a pin 30, which is anchored to a suitable casing member 31 which, in turn, is fixed in one of the slots in the casing. The operating crank arm 29a of the bell crank 29 is pivotally connected to the inner end of link 27 as by a shiftable pin 32. A gripping handle 33 is pivotally connected at the free end portion of the lever arm 2% of the bell crank 29 and permits easy operation thereof. In the form shown, the lever'arm 29b is somewhat longer than the crank arm 29a to facilitate easy operation of the mechanism.

Figs. 6 and 7 illustrate an alternative form of operating mechanism designated by the letter B. In form B a link 34 interconnects an intermediate portion of the bracing toggle arm 23 and a point on the periphery ofthe oscillatable actuating member which, in this form, consists in a pinion gear 35. A removable pivot pin 36 is provided at the outer connection of link 34 and a shiftable pivot pin 37 is provided at the inner end thereof.

The pinion 35 is journaled on a shaft 38, which is mounted in a suitable casing 39, which is fixed to the window casing 18. A worm 40 is formed on a hollow shaft 40b and is intermeshed with the teeth of the pinion 35 and has a pair of longitudinally disposed diametrically opposed keyways 40a internally formed in the 4 hollow shaft 40b. An operating handle 41 is pivotally mounted on a pin .42, which is slidably arranged in. the keyways 40a; the outer end portions of the keyways 40a are closed to retain the pin 42 therein. A pair of opposed crank-receiving slots 43 are formed across the end of the hollow shaft 40b, and one is adapted to receive the elongated operating lever of crank 41 when in operative position as shown in Fig. 7, and the other is adapted to receive the gripping handle 41a, when said handle 41 is retracted telescopically into the hollow shaft 40b.

It should be noted that the operating mechanisms, forms A and B, are designed for cooperation with only one of the two supporting hardware units H, which carry each of the sash members and, therefore, it is necessary to provide a sealing and locking device for the other side of each of the sash. This device is illustrated in Figs. l0, l1 and 12 and includes an operating handle 44 pivotally mounted in a suitable casing 45 by the pivot pin 46. An elongated latch book 47 has a downwardly curved rear portion which is pivotally connected to the handle member 44 as by a pivot pin 48 disposed eccentrically of the pivot pin 46. The forward end portion of hook 47 has a retaining shoulder 47a and an inclined camming shoulder 47b is formed at an intermediate portion of the lower edge portion of hook 47. A camming pin 49 is fixed to the casing 45 adjacent the forward end of carnming shoulder 47b when said hook member 47 is in :fully retracted locking position, and a retaining pin 50 is fixed to the window sash in a hook receiving recess formed therein.

The following is a description of the operation of my improved supporting and operating hardware as used in combination with my overlapped awning type window construction:

Each of the sash members has its own supporting, operating and locking hardware, and when the window is closed against the bumper strip 26, the crank 29a of form A of the invention is swung into over-center position with the pivot pin 32 disposed slightly below a straight line drawn through the pivot pins 28 and 30 to draw the sash stile at that side of the window tightly against the bumper strip. The other stile of each sash is securely held against the bumper strip by the hook 47. 7

To open the sash the book 47 is released by swinging upwardly on the handle 44 to project said hook member forwardly whereby the camming shoulder 47b operates against the camming pin 49 to raise the locking shoulder 47a above the retaining pin 50. By pulling outwardly on the handle 33 the crank arm 29a is oscillated on its pin 30 to project the link 27 outwardly and swing the toggle arms 23 and 21 outwardly and shift the slide 20 and the upper corners of the sash downwardly along the mounting strip 19. As best shown in Fig. 3, the inner edge of the top rails of the sash members are rounded off at the corners thereof to permit clearance of the bumper strip 26 as the windows are swung outwardly into open position. Also, the inner edge of the lower sash rails are rounded off. to provide clearance for the underlying upper rail of the sash disposed immediately therebelow when it is desired toopen the lower sash without opening the upper sash member. When a sash is swung outwardly to about 45, the crank arm 29a is swung over into the dotted position of Fig. 5 and the lever arm 2% is swung up into the upper dotted position in substantially straight line relation to the lower closed position. 7

In form B of the invention, the crank handle 41 can be retracted into the tubular shaft 40b as shown by the dotted position of Fig. 8 to almost fully conceal the same, and when it is desired to open the window said handle is merely pulled out and swung over into one of the slots 42 to turn the worm 40 and the intermeshed pinion 35 to project the link 34 and toggle arms 21 and 23 outwardly, as described above. ;The locking hook 47 on the other. side of each sash is the same for both form A and form B of the invention.

It will be seen that I have provided extremely simple, highly efficient, operatinghardware adapted to work in close cooperation with my overlapped awning type win dows and the supporting hardware shown herein whereby each sash may be individually andindependently operated. The removable pins 28 and 36 may be taken out of the r spective apertures to permit the sash to be manually swung into extremeopen position to facilitate cleaning thereof from the inside. As brought out in my above identified co-pcnding application, this type of awning window is extremely easy to Weatherstrip and the improved hardware mechanism herein disclosed permits easy operation thereof without removal of the screens which must, of necessity, cover the inside of the window and may be fixedly mounted to the frame 18.

It will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts without departing from the scope of my invention.
