.. 5 claims.- (C1. 15e-17) This invention relates to awnings andv particularly to awnings of the multi-vane or shutter class.

One type of awning of this class which has been proposed heretofore is constructed to be installed on the outside of a window or rother opening to a building, or over a porch or balcony or the like, and comprises a, frame carrying a plurality'cf pivoted movable 'shutter vanes s which may be opened to admit light or shut to exclude rain, etc., the entire awning structure being disposed outwardly of the building so as not to interfere with the normal operation of the window or door at the opening. It is to this type of awning that the present invention more particularly relates..l

It is among the objects ofthe invention:

To provide generallyy an improved shutter typ awning construction;

To providev an awning of the' class referred to constructed to permit of its use with outwardly opening easement windows, doors, etc., in an improved manner;

To provide a shutter type awning comprising a plurality of pivoted shutter vanes adapted to open or close in a predetermined sequence;

To provide an improved pivotal support for the shutter vanes of a shutter awning of the type referred to;

To provide an improved operating mechanism for opening or closing the vanes of a shutter awning of the type referred to;

-To provide in a shutter type awning structural elements adapted in .an improved manner to be used in different sizes of complete awnings;

To provide in shutter type awnings in which shutter vanes are pivotally moved by a lever,

improved means for varying the operating lever` ratio;

To provide a shutter awning which may be cheaply constructed, and which will be convenient to install or to remove from its' installed position, and which will be easy to operate and dural 'but this feature is optional.

' horizontal as plainly shown in Fig. 1.

Fig. 2`is a front elevational view of the shutter of Fig.` 1;

Fig. 3 is a view similar to Fig. 1 illustrating jfragmentarily a modiiication lof thel shutter of Fig. 1. y 5

Referring to the drawing, I have shown generally at I the frame of a window having an upper. sash 2-2 and a lower sash 3 vertically slidable therein by the usual construction. 'I'he shutter awning about. lto be described is installed 10 outwardly of the upper sash so that an unobstructed view may be had through the lower sash. The awning structure is assembled upon a base element 4 which may conveniently be constructed fromv wood in the form of a. board or strip of 15.'

such sizeas to be suitably secured upon the outer surface of the building, as for example upon 'the upper transverse portion 5 of the window frame. The base also comprises an upper stationary shutter vane B to the underside of which 20 are secured hangerslformed from bar metal bent into V-form with one leg secured to the underside ofthe stationary shutter vane 6 by bolts 8'$ projected through the vane 6 and through the said legs, the other leg 9 being ver- 25 'ztically disposed and secured to the outer face of the strip 4. If desired also, the legs 9 of the hangers 'I may be permanently secured to vthe strip-4 by screws III-I0, shown only in Fig. 1,

'I'he upper edge of the stationary vanev is notched out as shown at II, upwardly through which notches the hangerlegs 9 may project so that the upper edge of the vane 6 may be disposed in water-proof contact or engagement with 35 the strip 4.

Also, to the underside of the stationary vane 6 are secured as by bolts I2-I2, a pairof laterally spaced rails I3-I3, the upper' ends of the rails being bent at a relatively acute angle to the hori- 40 zontal so that they may lie flat against the under- "side of the stationary vane 6 and the lower portions of the rails I3 being preferably rectilinear and disposed at a relatively obtuse angle to the s 45 By this arrangement, the mutual cooperaticn ofthe vane'6 and rails I3 is attained whereby the rails may be securely attached to the Vane 6 by conforming thereto over a relatively great extent and at the same time the vane 6 may be inclined 50 at an angle to the lower portions of the rails I3 to act in the nature of a first vane or water shed and overhang said lower portions of the rails as shown at I4.

The lower ends of the rails I3 are connected by 55 a transverse, preferably metal, barl I5, and the bar I5 and therefore the rails I3 are secured byy their lower ends to thebuilding face such as to the outer surface o f the window frame thereof by 5 a pair of strut elements I6, outer ends of which are secured to the bar I 5 and inner ends of whichv I'I to the building or winter arm pivot support to be described in a planek y at right angles thereto. j

Each rail I3 in one leg of the angle when angle iron is employed, is provided with a plurality of ,longitudinally spaced perforations- I3--I3, andbetween each pair of perforations I8 the rail Iis` perforated to receive bolts or rivets .IS-I9, uponl which are pivoted to oscillate in a common verti-r cal plane shutter vane arms 2li- 20; formed from sheet metal', the rivets I9,projected through perfo,-n

rations in the arms 20 and through the said perforations in the rail I3. The yinner ends of the arms 2li-20 are pivotally riveted by rivets 2I-2I toa bar 22 in perforations having the same 'spacing as those for the Yrivets I9I9 and the bar, 22 being disposed parallel to the rail I3 whereby l a parallelogram movement mechanism is provided.

The outer ends of the arms 2li are bent downwardly to provide shutter vane supporting portions 23-23 to which are secured shutter vanes 24-24, the vanes being disposed'horizontally and` opposite ends of the vanes being secured to corresponding arm portions 23 on opposite rails |3-I3.

'I'he arms 2li are preferably constructed from sheet metal with the depending portion 23 inthe same plane with the above mentioned pivoted portion 25, and to provide a seat for the shutter Y vanes 24the portion 23 has a wing 26 bent at a right angle thereto and bolts orrivets 21-21' are projectedI through aligned perforations in *thel vanes and in the wing 26. By this constructionof4 arms, the maximum of strength throughout for the minimumof material is provided, all tendencies for the arm to bend being resisted by the width or depth of Athe arm considered as a lever, which depth is maintained throughout as would not be the case, for example, if the arm were twisted to provide la ilat seat for the shutter vanes, and at the same time the said flat base for the shutter vanes is provided by the angularly bent wing 26 without detracting from the strength of the arm. Y 'I'he bar 22, besides having the necessary spaced perforations for the rivets 2Iof the shutter arms,

' 60 has spaced perforations 28-23 corresponding to the perforations I8v between adjacent arms. There are thus provided a plurality of pairs of perforations longitudinally of the rail I3, one of each pair being in the rail and the other in the bar 22.

An operating lever 29,I preferably formed from sheet metal and of the general form of an obtuse bell crank, has one leg 3l)A 4thereof lpivotally riveted as at 3I-3I to the rail I3 and bar 22 in one pair of said perforations and with the other leg 32 generally inclined upwardly. A flexible element such as a chain 33 is connected at the outer end of the leg 32 of the lever, indicated generally at 34, and the other end of the chain extends downwardly and passes through a hole or bore 3,4 extending through the building to the interior thereof at one side of the lower sash 3,l and terminating in a suitable handle 35 inside the building. I

As will now be apparent, if an operator in the 5 buildinggrasps thel handle 35 and pulls on the chain 33, the lever4 23r will operate the parallelogram movement mechanism above described andoperate the shutter vanes 24 either to move them generally downwardly to a completely overlap- 10 pingclosed position or to raise'them to the open position illustrated or' to an even higher more open position; and -in any operated position, a' link of thechain 33` may be looped over a pin or lhook or other device 36 in the building to hold 15 the shutter vanes in the adjusted position.

The lever 2.3` may be located at an upper, intermediate, or lower portion of the shutterv con, struction by disposing the rivets 3I-3I in one oranother of the above described pairs of per- 20 forations inthe rail I3 and bar 22 to change as may be desired the angle at which the chain 33 pulls on the lever 341, so that no matter in what location the bore or hole 34 is disposed, a corresponding leverage relation may be established 25 by/ suitably positioning 4the lever 23.y To this end, instead of using permanent rivets 3I3I,` removable bolts may be used so that the optimum leverage relation may be attained at the time of installing the awning at a window. so

'In Some cases it is preferred to provide the arms 20 long enough to extend inwardly beyond' the bar 22 and to provide in their 4ends' another perforation such as'that shown at`3I-3'I. The arms 20, with this provision, may all be made 35 alike with the said extraset of perforations and when assembled in a relatively small awning, the inner perforations may be used becauseI suiiif cient leverage in. the parallelogram movement mechanism will be present therein; but when 40 l the same arms are lassembled in a larger awning, greaterleverage may be wanted and vthen the outer set of perforations 31-31 may be used in riveting the bar 22 to the arms. When a small shutter is assembled from the arms which can 45 thus be made in great quantities for both large and small awnings, it is` desired to have the bar 22 relatively close tothe'rail I3 for the sake of` neatness and compactness in appearance.

As will now be apparent, the entire shutter 50 may be assembled at a factory including the base strip 4 and may be attached to the building or installed in position for use by mounting the strip 4 upon the building and securing the strut I6; then, after it is decided where the bore 34 55 shall be'for convenience to the operator in the building, the lever 29 may be pivotally attached in operative position at an upper jor lower or intermediate /portion of the awning as may be best so Y In the modification illustrated -in Fig. 3, the

upper part of the awningA indicated generally at 33v is disposed at a more acute'angle to the horizontal' than the lower portion indicated generally at 33. The lower portion 39 having rails 55 I 3a, a bar 22a, shutter arms 20a- 20a yand shutter vanes 24a-24a as well as the lever 34a and operating chain 33a may all be like or similar to the correspondingly numbered parts of the form of Fig. 1.. In this form, however, the upper por- 70 tion of the rail rI3a as at v4|I which is secured to the underside/of the stationary vane 4I is elongated and has a pluralityof arms 42-42 pivotally rivetedl thereto' carrying vanes 43-43. These arms and vanes may be identical or sim- 75 iler to the above described arms and vanes. The inner ends of the arms 42 are pivotally riveted to a bar 44 providing with the rail portion 40 and the arms 42 a parallelogram movement mechanism. The lower end portion of the bar 44 and the upper end portion of the bar 22a are pivotally connected to a link 45, the connection having lost motion therein. This lost motion may be provided by various means but I prefer to provide it by means of a slot 4G in the link 45 where it connects with the lower end of the bar 44, there being at this point a common rivet 41 extending through the slot 46 and through the end of the lowermost arm 42 and the lower end of the bar 44. As will appear hereinafter, this slot may be provided at the upper end of the bar 22a and in other locations, the exact location and nature of the lost motion not being essential.

Except for the alternative form of the stationary vanes 4| shown in this figure, the construction of the upper end portion or base of the awning by which it is attached to the building or window frame may be the same as that described for the form of Fig. l.

In the operation of the form of Fig. 3, when the chain 33a is pulled, the shutters 24a will be moved to an open position, preferably ap-v proximately one-third of the full-open movement, and at this point of operation, the lost motion provided by the slot 46 will all have been taken up by the downward movement of the bar 22a and link 45, and further movement on the chain 33a will cause the arms 42--42 to be rocked to initiate opening of the vanes 43-4-3, and further movement will open them to any desired degree.

Thus, in some kinds of weather, it may be desired to admit light through the vanes 24a and at the same time have shelter from rain by the varies 43.

The rail 40 by extending outwardly in a relatively horizontal direction or at a relatively slight angle to the horizontal, provides room under the awning as a whole for outwardly swinging doors, easement windows, etc., one of which is shown at 48, so that the awning of my invention may be installed at doors or windows of this type as well as at the more usual type illustrated in Fig. 1.

When the rails 40 and i3d are made from a single piece o angle iron as illustrated in the drawing, the bend at the juncture of the two portions may be provided by sawing the Vertical flange of the angle iron as at 49, and the bent rail may be stifened or strengthened by a brace bar 50 secured at opposite ends to rail portions. Of course, as will be understood, if the above described sequence of operation for the shutter varies 43 following opening movement of the vane 24a and preceding closing movement thereof is not wanted, it is only necessary to use a link 4I without the slot 45.

It will be apparent that changes and modifications may be made in my invention within the scope of the appended claims so that my invention is not limited to the exact construction illustrated.

`I claim:
