To all whomit may concern:

Be it known that I, CARMnLo GUGINO,

I a citizen. of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Window Shutters, 'of which the following is a specification.

This inventlon relates to window shutters and more particularly to that type of shutand which is foldable into a compact form.-

window" frame showing my improvement applied thereto, the shutter being in its unfolded or closed position. Figure 2 is a vertical transverse section on line 2-2, Fig. 1. Figure 3 is a horizontal section on line 3-3,- Fig. 1, showing the shutter in its lowered and folded position. Figure 4 is a fragmentary erspective view, on an enlarged scale, of die lower portion of one of the uide rails. Figure 5 is a perspective view of one of the closures. Figure 6 is a transverse vertical section of a modified form of the. improvement.

Similar characters of reference indicate 'cerresponding parts throughout the several views. Referring .to the construction shown in Figs. 1-5, 10 represents the window frame which may be of any suitable and welt known construction, the frame shownin: the drawin including the'uprights or

stiles

11, 11, the msidesill l-2'and theoutsideflsill 13.

Arranged underneath the inside-sill is a compartment, pocket or housing '14 which extends substantiall the full width of thewindow frame and 1s ofsuflicient depth and breadth to encase the shutter iniits folded or collapsed position. {A hinged lid or cover 15, forming part of the inside sill, normally closes the open u per end of this compart ment. To each '0 thestilesdl 1s securedv a vertical guide rail or'way 16which is preferably constructed in the form of a channel bar whose rearside or flange 17 is of greTter Specification of Letters Patent.

- width than its front side or flange is for a Patented Feb. 28,1922.

purpose hereinafter described. 7

The shutter, in being raised and lowered, slides in the guide rails 16 and is preferably constructed as follows:

19 represents a plurality of hinged shutter-j sections or leaves of fireproof material which extend transversely of the window opening, the ends thereof terminating short 0 the corresponding edges of the front sides 18 of the guide rails, as shown in Fig. 1. These shutter sections are adapted to be PAENT orrli'ca;

folded upon one another in lo-wiering the shutter and to be unfolded in raising the shutter, and for this purpose the'seweral sections are connected with one another by alternately long and short hinge-pint1es20 and 21. The ends of these hinge intles extend beyond the corresponding upright edges of the shutter sections and are guided 1n the rails '16. In lowering the shutter, each pair of adjacent sections is adapted tobe folded inwardly,

and to this end the front sides 18 of the.

guide rails are provided with notches-or exit-passages 22 adjaient their lower ends which permit the she t hinge pintles to be withdrawn through said notches while the long hinge pintles remain in their guide rails. These notches are out only of such depth as to permit the shorthinge pintles, to be moved into and out of engagement with said rails, the long pintles bein per-u manently confined within said rails the raislng and lowering movements of the shutter. y

A suitable closure 23 is provided for each notch or assage 22 to normally retainfthe short pint ies in the guide rails and prevent the shutter from accidentally lowering or collapsing while in use. These closures are uring preferably carried by actuating levers 24 pivoted at their upper ends to theguide rails'so as to be capable of swin 'ng transversely "of the shutter, the levers ing provided at their lower ends with suitable knobs 25 for actuating them. In order to hold each of these levers in its" normal position,-an offset lug or lip 26 is 'rovided on,

the front side 18 of each gui e rail, said lever being adapted to be frictionally en aged between said side and said hese levers normally extend downward y into the compartment 14 through notches 27 formed in the adjacent corners of the lid 15, as shown inFigs. 2 and The lid thus locksthe levers in their normal levers are swun positions, making it necessary to first raise the lid in. order to release the levers and permit the raising or lowering of the shutter.

Any suitable means may be employed for raising and lowering the shutters, but those shown in the drawings have been found appropriate and consist of pulleys or

drums

28, 29 and 30, suitably supported in the upper end of the frame 10 and a pair of elevating cords, or

cables

31, 32. passing around saidpulleys and each connected at one end to the long pintle 20 of the uppermost shutter section 19. As shown in Figs. 1 and 2, the cable 31 passes around the

pulleys

28 and 29 while the'cable 32 passes around the pulley 30, the two cables being joined at their free ends, as shown at 33, whereby they are actuated simultaneously for effecting a uniform raising and lower ing movement of the shutter.

To permit of conveniently collapsing or folding each pair of adjanent'shutter sections mwardly in the act of lowering the shutter, actuating devices are provided which preferably consist of rings or finger pieces 34 secured to alternate sections.

As before stated, the rear flanges 17 of the guide rails are wider than the front flanges 18, said rear flanges overlapping or extending beyond the adjacent upright edges of the several shutter sections, whereby a closed joint is rovided'between the exterior sides of the s utter sections and the guide rails, preventin the passage of smoke and fire through t e same.

To raise the curtain from its open and folded position, shown by dotted lines in Fig. 2, to its unfolded and closed position,

shown by full lines in the same figure, the

lid 15 is raised to open the compartment 14, afterwhi'c-h the levers 24 are elevated to the position shown by dotted lines in Fig. 1 to uncover or 0 en'the notches 22 in the guide rails 16. e cables are now pulled to successively unfold the shutter sections 19 until they are all elevated, after which the sition and the Ii 15 is lowered. The shutter is reliably retained in its u right position by the hinge intles 20 an 21 engaging. the guide rai s and the same is held against accidental. folding or displacement by the levers and the lid.

To lower and open the shutter, the'lid 1 5 is raised, ,the levers are disengaged fromv their notches 22, and the shutter sections successively folded inwardly in pairs by s ing the corresponding rings 34 and pulling the -,short pintles throu h said notches, each pair drop ing to folrfied position by gravity into t e compartment 14.

' ,Thelevers may then beswun to their normal position and the lid close thereby concealing back to their normal pocomprising a the shutter from view when not in. use and'protectmg it. I

In the modification of the improvement shown in Fig. 6, the shutter sections are not concealed or stored in a compartment, as

in the preferred construction, but rest on the inside sill 12 and are exposed. Otherwise the construction is identical with that previously described.

While this shutter has been shown and comprising a pair of opposing guideways,

and a plurality of hinged sections connected by pintles engagingsaid guideways, the latter being provided in their sides with pintleinlet and exit passages for permitting movement of alternate pintles into and out of engagement with the guideways.
