This invent/ion relates to metal awnings and has for its object certain improvements in the construction of metal awnings. The invention relates more particularly to improvements in the construction of sheet metal awnings.

Although metal awnings have heretofore been proposed, they have had little or no commercial use. This is, of course, due in part to the fact that it costs more to make metal awnings than the conventional cloth awnings. While the cost of metal is greater than that of the cloth, fabricating costs are also involved. A metal awning is proposed in United States Patent 1,030,493. Its however, is so involved that it has probably never had any commercial application. Another metal awning is proposed in United States Patent 1,795,521, the construction of 'which is somewhat simpler. In both awnings, a series.

of horizontal sheet metal strips, including a curtain, are hinged and adapted t be folded against one another.

The present invention is concerned with improvements that simplify the construction of metal awnings, while at the same time making them rugged. They may be easily operated. In accordance with the invention, the bottom p0rtion o! the awning is so constructed-as to add considerable rigidity to the whole structure. A special this purpose. The awning curtain is doubly hinged along its upper portion with the.. crossbar andfthe lower horizontal sheet metal cross strip, so as to tend to lock 40 a plurality of intermediate horizontal metal strips, preferably of substantially uniform width, which are so hinged that they overlap in the same position when the awning is closed. This overlapping is soarranged. that the metal strips 4s always fold relatively to one another in a predetermined Y direction.

-In a preferred practice, a pair of opposed pintles is provided in selected joints of the horizontal metal strips. These pintles are provided 50 with a ring at their exterior ends to support an awning cord. The pintles may be withdrawn to break the awning into smaller units for packing and shipment. They may be readily reinserted in their hinges for assembly and installation of 55 theawnins.

cross-bar construction is employed forv the curtain and thev lower metal strip when the awning is in its 35 open" or down position.

1935,'Serial No. 20,911

The invention also contemplates an improved canopy construction. It functions not only as a canopy torcover the awning when in its closed position, but also as a means for supporting the awningr against a window frame or the like.

The canopy also shelters and supports a pulley housing arrangement that is highly useful and oers an improvement in the operation oi.' awnings. Each housing is provided with a pair oi' pulleys specially `positioned to accommodate an awning cord and to insure easy running of the same.

These and other advantages of the invention will be better understood by referring to the accompanying drawings, and the following description, in which: 1

Fig. 6 is an enlarged fragmentary side elevation in section of the awning in its closed position;

Fig. 'l is a fragmentary detail in section on the Vline 1-1 of Fig. 6, showing the left hand pulley housing and canopy holding means;

Fig. 8 is a front elevation of the pulley housing and canopy holding means shown in Fig. 7;

Fig. 9 is a perspective view of the canopy holding means shown particularly in Figs. 6, 7 and 8;

Fig. 10 is a perspective view of the awning in its closed position, with fragments broken away to disclose the pulley housings and canopy holding lap, which strengthens the curtain. It is clear that the curtain and strips maybe treated to show any desired design for ornamental purposes. The awning is provided on each side with a side 5 arm I3 attached to a window frame I9, or the like, by means of a clevis 20. 'Ihe far end of the side arms terminates in side rod ends 2|, such 'as ornamental spear heads. Running flexible cores 22 extend from the inner ends of the spear l0 heads across ythe horizontal sheet metal strips to pulley housings 23 located directly underneath a canopy 24 at the upper end of the awning.

The side arm I3 is preferably made of metal tubing, the end fastened to the window casing being screwed into a side rod end 2l that is pivotally connected to the clevis by means of a clevis screw 26. 'Ihe other end of the side arm I3 is provided with internal screw threads adapted to receive the indented end of a side rod stud 2l.

l The diameters of the stud and side arm are the same. 'The other end of the side rod stud is threaded to receive the spear head. The side rod stud may thus be regarded as an extension of the side arm itself.

.25 4 'I'he side arms I3 are spaced a predetermined distance by means of a spaceror crossbar 2l. A sheet metal gusset plate 23 connects each end of the spacer-bar with the remote end of the side arm I3 and its side arm stud 2I. The gusset 80 plate is riveted along one: side thereof to the spacer-bar. f The outer edge portion of the gusset plate is bent over itself, as shown in Fig. 2,

to form a hollow interior` or cylindrical side adapted to receive the remote end of the side 3.5 arm I3 and its side rod stud 21. Ihe bent over edge portion of the gusset plate is riveted or otherwise attached to itself, such as by spot welding. 'I'he side rod stud 21 is permanently fastened on the inside of the cylindrical side 3U.

l such as by rivets 3l vextending completely through the side walls of the cylindrical portion and the stud. Means, such as a hole 32, are provided near the remote end of the cylindrical portion oi' the gusset plate for attaching the running ilex- 5 `ible cord 22. The hypotenuse edge 33 of the gusset plate is advantageously bent over itself in Vorder to stiilen the gusset plate.

A spacer-bar hinge section 34 (Figs. 4 and 5), preferably constructed of thin sheet metal, is ato tached to the under side ofthe spacer-bar 23. such as by means of rivets' or spot welding. A so-called piano" hinge 'is formed by means of notched portions of the sheet metal extending beyondthe far side of the spacer-bar and turned 55 over into the form of small cylindrical sections to form pintle eyelets 35. A curtain secondary hinge section 3i is attached to the curtain i I, such as by rivets or spot welding.` directing below the spacer-bar 2i.. The secondary hinge section 36 so ls provided with notched side portions bent around into small cylindrical sections to form pintle eyelets 3I;-so alternated as to be in alignment with the pintle eyelets 35 of the spacer-bar hinge sections. A pintle 33. in the form of a round bar es er metal, extends completely through the aligned pintle eyelets. The ends of the pintle preferably terminate with the side edges of the curtain il. The upper portion 33 of the curtain extends an appropriate distance above and over the 70 spacer-bar 23 and the pintle 3. 'I'his upper .por-

tion of the curtain is advantageously bent in or indented to form a rounded shoulder 43, protruding over the hinge forming around the pintle 33. The upper portion of the curtain is bent around along its longitudinal edge in notched sections to form pintle eyelets 4I.

'I'he lower sheet metal strip I2 has its lower longitudinal portion 42 bent in the form of an obtuse angle 43. This lower longitudinal portion l is in turn bent back over itself in'the form of an under lap 44, the upper edge portion 4l oi' which is bent to conform to theobtuse angle 43. This upper edge portion is notched in spaced sections, the notched sections being bent around to 1I form pintle eyelets 46 adapted to be aligned with the pintle eyelets 4I of the curtain II. A pintle 4l extends completely through the aligned pintle eyelets, to form another piano hinge that may Y be regarded as a curtain primary hinge. In the l5 construction shown, the curtain primary hinge is stationed directly above the curtain secondary ,hinge and above theobtuse angle 43. 'Ihe lower longitudinal portion 42 of the metal strip I2, together with its underlap 44, leans against the 20 outside of the curtain II along its upper longitudinal portion, and thus operates as an effective stop to movement of the curtain. In other words, the construction shown tends more or i less to lock the curtain II and the lower sheet metal 25 strip i2 when the awning is in its open position, conforming to the obtuse angle 43. 'I'he size of the obtuse angle is fixed so that the curtain hangs vertically when the awning is down, and the lower metal strip i2 has a slant conforming substan- 30 tlally to that of the other metal strips. Lower sheet metal strip I2 is pivotally attached to the intermediate sheet metal strip I3 by means of a piano hinge 48. 'Ihe upper longitudinal portion of metal sheet I2 is provided with an in- 3.5

dented shoulder portion 49 bent back over itself in an overlap to form a double thickness of sheet metal. The lower edge of the overlap is notched ln sections, which are bent'around into pintle eyelets. The eyelets in turn fit at least in part 4o within the indented shoulder portion of the metal strip i2. The lower longitudinal edge portion of lintermediate metal sheet I3 is also notched and bentaround into pintle eyelets, which are aligned with those of sheet I2. A pintle extends completely through the aligned eyelets. 'I'he indented shoulder portion 49 of the metal sheet I2 extends an appropriate distance under the lower portion of the intermediate metal sheet I3.' to assist in locking the two adjacent metal sheets so along their joint when the awning is (down and thus cause the two sheets always to fold toward one another in the same pre-arranged direction. In the case of sheets I2 and I3, their outer lurfaces will always adioin one another when the awning is closed. 'I'he indented shoulder portion 49 effectively prevents the two metal sheets from folding in the opposite direction.

A similar form of piano hinge construction is provided between intermediate horizontal metal strips I4 and I5, as well as between intermediate metal strip I6 and upper metal strip I1.

Intermediate metal strips I3 and I4 are like# wise joined by means of a piano hinge 53. In this case the upper edge of metal sheet I3 is notched 35 and the sections thereof are bent around into pintle eyelets. Sheet metal strip has its lower portion 5I bent back under itself to form a double bend, the upper edge of the underlap be- Y ing notched and the sections thereof are bent around into pintle eyelets, which are aligned with the pintle eyelets of sheet metal strip I3. Two pintles 52 are fitted into these eyelets from opposite directions, each pintle extending halfway across the metal strips. Each pintle is provided back wall I1 of the canopy is aoeasso Intermediate metal strips i5 and Il are joined' in a similar manner, two opposed pintles, likewise, being used, so that the awning cord may be supported through the outer rings of the pintles.

tage that they may be pulled out of their pintie eyelets, and the adjacent metal strips may then be disconnected, so that the awning may be broken into smaller units for packing into a relatively small .space for convenient shipping.

At the same time this pintle construction permits easy assembly of the units when the awning is to be installed. Since the awning cords are drawn tautly, the pintle halves will stay in position.

It will be noted that the hinges are alternatively disposed with respect to their return-bend portions. 'Ihis construction insures a semi-rigid arrangement of the metal strips. and causes the strips always to fold in the same predetermined direction.

The canopy 24 serves a'four-fold function. In addition to acting as a cover to the awning when closed, it accommodates a pulley housing holding means 54 for attaching the awning to a window frame, or similar support, and a hinge l5 to connect with the upper metal strip I1.

The canopy comprises a bent over roof portion 5t adaptedto cover the awning when in its closed position. The outer edge of the roof is preferably beaded to give added rigidity. The l with the bent over roof portion. In the construction shown, the roof portion of the canopy covers a left hand pulley housing at one end, and a right hand pulley housing at the other end. The pulley housing consists of an outer metal casing Il in which are located an upper pulley Il and a lower pulley 60. The nrst pulley is located close to the roof, and to the front of the canopy, preferably clear of the side edges of the metal strips, and is attached to the housing by means of a rivet. This pulley is aligned to accommodate the exible cord 22 extending through the pintles. A portion of the metal housing is cut away. as shown, so-that the cord may have free and unimpeded access to the pulley. The second pulley is located at the rear of the metal housing,

at a right angle to the first pulley. This pulley is located at a convenient level below the nrst pulley so that the awning cord may be drawn across the top of the first pulley and underneath the second pulley,-in the case of the left hand pulley housing.

The right hand pulley housing is constructed in substantially the same manner, except that the pulleys are oppositely arranged. In the case of the right hand housing, the awning cord from the left hand housing extends across the top of the second or lower pulley in the right hand pulley housing. 'Ihe awning cordon the right hand side of the awning passes over the nrst or upper pulley Vof the right hand housing. Both cords drop vertically alongside of one another,- and are jointly pulled or released to operate the awning.

In the case of both pulley housings, in the con struction shown, a bent over shoulder portion 6| of the roof of the canopy is riveted to the pulley housing, to keep the housing in position.

These opposed pintles have the advanl The inner end I2 of the pulley housing adjacent to the back wall of the canopy is advantageously provided with a slotted hole 63 registering with a similarly slotted hole Si in the back wall of the canopy. adapted to cooperate with the holding means M. The back wall. of the canopy is provided with an indented portion l5, as shown, to accommodate the holding means il, so that the back wall and the holding means may be substantially flush with the window casing or other support. y

The holding means comprises a hat faced hold ing stud base adapted to iit within the indented back wall portion i5 of the canopy. The holding base is provided with two oountersunk holes to accommodate securing screws i1.

countersunk bolts or the like, which fit into the window frame or other awning support employed. One side of the holding base is provided with a stud bolt il and a nut". A self-locking nut is preferably employed.

A ring holder 1l is attached to the crossor spacer-bar 28 at its midsection. A ring 1i is held by the holder. and carries a `cord 12 which y is employed to hold the awning taut when it is in its closed position, such as by fastening the cord to a window sill in the conventional manner.

In closing the awning, the cords 22 are simultaneously pulled. They 'support the hinged, horizontal metal strips'at the pintle rings 52. As shown, the hinges are so arranged that when l the metal strips are folded the alternate hinges with pintles i2 are always uppermost (see Fig. 6). The folded part of the awning may be pulledunder the roof of the canopy.

when closed or open the awning offers protection against rain and snow in the use of an upper window as a' ventilator. The upper window may for example be lowered several inches or more.

The awning provides a passageway for the movement of air through the lowered upper window, but keeps out rain or snow. This. arrangement is particularly desirable with the awning in its closed position.

From the foregoing d ription, it will be seen `that the improvements in the awning of the invention offer a number of important advantages.

The awning is so constructed that it may be packed in a relativelywrnall space for shipment: it may be readily assembled and installed. It may be taken down easily. The metal strips are so jointed or hinged that the awning as a whole is substantially noiseless in wind or storm.
