This invention relates to new and useful improvements in window awnings formed of sheet metal or other suitable rigid material.

'Among the objects of the invention are to sition.

Another object of the invention is to provide an awning section operating means including novel worm screw and sleeve equipment by employment of which it is possible to positively and substantially noiselessly move the sections to the open or collapsed positions with a minimum of ei'ort and without the need of utilizing lock detent or like equipments for securing the parts in adjusted positions.

With these and other objects in view which will more fully appear, the nature of the invention will be more clearly understood by `following the description, the appended claims, and the several views illustrated in the accompanying drawings.

In the drawings Figure lis a perspective view of an awning and operating means therefor which embodies my invention, the view showing the awning telescoped or collapsed and attached to a window casing.

Figure 10 is a detail sectional view illustrating the engaging portions of several of the awning sections which have been partially telescoped.

Like reference numerals designate corresponding parts throughout the several iigures of the drawings.

In the drawings, I have disclosed the invent-ion mounted on a window casing A which includes the usual ceiling beam 1 and

side walls

2 and 3.

The awning comprises a plurality of sheet metal or other suitable rigid material sections which are nested or telescopically arranged to swing about pivots whereby the ma be easily collapsed or extended. Pre era ly the awning comprises an attaching or top section B, a bottom section C, and a plurality of intermediate sections D, D' and D. The attaching section B comprises

triangular sides

4, 4 and a rectangular top or connecting portion 5 which is curved in cross section as illustrated in Figures 1 and 2. Each side 4 is provided along its casing engaging edge with an inwardly extending integral flange 6 and along its outer edge with a spacer flange-7 formed by bending the edge of the metal back upon the body as shown in Figures 9 and 10, and along its to edge with an inwardly extending fiange 8, t e top 5 being ri idly connected to the top flanges 8 of the si es by rivets, welding, or other means. The

top 5 is provided along its rear edge with a depending inte ral flange 9. The section B is rigidly attac ed to the window casing by screws or other fastenin means which pass through the near side anges 6, 6 and to flange 9. The lower edge of the flange 9 1s referabl rebent as lat 10 to-reinforce the ange. 'ghe top 5 along its front edge is provided with an integral dependin flange 11 which terminates in an angularly nt inwardly extending lip or flange 12 which constitutes -a sto and support forthe other sections when the :latter are extended, and also reinforces the depending flange 11 suffieientlyI to enable it to withstand the load of tlie other sections without buckling.

The intermediate sections are of like construction and therefore a description of one section will suffice. Each of these intermediate sections includes

triangular sides

13, 13 and a flat 'rectangular top or connecting portion 14 which may be flange-secured to thesides as indicated at 14. Each side 13 is provided alon4 its inner edge with an inwrdly exten ing integral flange 15, and

A, along `its o uter edge with a spacer flange 16 formed by bendingthe edge of the metal body back upon itself. The top 14 is provi'ded along its inner edge with an upwardly extending longitudinal flange 17, and along its outer-edge with a downwardl extending longitudinal flange 1'8 which erminates in an inwardly extending longitudinal ange :19.`I A

The bottom section C is similar to an intermediate section except that it lacks the

flange

18, 19, and instead is provided 'with an inwardly directed channel bead 20 to which a sheet metal apron 21 is flange-secured as indicated in Figures 2, 5 and 9 of the drawings. l "i The intermediate-sections D', D, and the bottom section C, are independently pivoted to the intermediatesection D by pivot pins 22, 23 and' 24, the pins connecting the sides of the respective sections. Thus the intermediate sections D',l` D2 and the bottom section C 'constitute a unit, and this unit is adapted to be pivotally attached to and detached from the attaching section B by pivot bolts f1," which respectively engage the sides 4 of the attaching section B and the adjacent 60.' the possibility of rain and other foreign elesides'13 of the intermediate section D.

Thus, assuming the awning sections to be l extended, a lifting force imparted to the bottom-section C, will cause the intermediate sections to be lifted therewith by reason of thefianges '15 engaging one another in succession. The flanges 7 of the section B and the flanges 16 of the intermediate sections r constitute spacing means and reduce to a minimum friction between said flanges and the vadjacent sections with which they slidably-engage, as well as strengthen the sides of the sections, and also reduce to a minimum ments entering therebetween.

The

ends

4, 4 of the rear section B are provided with pressed out

ventilator openings

25,25.

' The flanges 18 of the intermediate sections other end, preferabl and the flange 11 of the top section coo erate with the flanges 17 of the intermediate and bottom sections when the sections are extended in forming limiting stops limiting extension movements of the sections to extend the sections, and the flanges 19 of the sections D D and Dz and the flange 12 of the section function to reinforce the flanges 18 and 11.

In orderto positively collapse and extend the awning, I haveprovided the following mechanism Journaled in

hangers

27, 27 secured to the rear depending flange 9 of the attaching section B is a rock shaft 28 having

crank arms

29, 29 at its opposite ends and projecting in the' same angular direction. connected to each crank arm as at 30 is the up er end of a link, 31, the lower ends of the lin s beingrespectively pivoted as at 32, 32y

Pivotally- The lower end of the bar is removably connected as at 36 to a worm rod 37 which is lmovable up and down through apertures rovided therefor in the upper and lower egs of a stirrup or bracket 38 secured to the window casing. Within the bracket 38 the.

worm rod 37 threads through a worm sleeve 39 which is rotatable but is held against longitudinal movement by reason of being confined between the upper and lower legs of the bracket 38. The sleeve 39 carries a bevel pinion 40 which meshes with and is driven by a similar pinion 41 mounted upon one end of the operating shaft 42 which is rotatable in a suitable bearing provided therefor in the window casing and has its extended through to the interior of the uilding on which the awning is mounted, equipped with a turning crank 43, A suitable removable cover 45 may -be provided to protect the sleeve and gears ployment of worm screw connections the parts are automatically secured at all positions to which they are adjusted and it is unnecessary to employ locking detents or similar equipments for this purpose.

The clamps 33 are adjustable along the channel beads 20 to perimt of the operating parts being properly fitted to the awning.

From the foregoi it will be observed that my awning may readily ap lied to a window casing or removed there rom. In applying the awning the attachin section B is first secured to the casing, am? it will be noted that the rock shaft 28 Ahas been previously mounted in the hangers 27 which are attached to the rear flange 9 of said attaching section. The remaining sections D, D', D2 and C which have been previously pivotally connected, are then attached as a unit by the pivot bolts :v to the sides of the attaching section B. The links 31 are then connected to the cranks 29 of the rock shaft and to the channel beads 2O of the bottom section C. The operating shaft 42 and handle 43 and the bracket 38 are then mounted on the window casing and the worm sleeve inserted between the upper and lower legs of the bracket with its bevel pinion 40 in mesh with the pinion 41 carried by the shaft 42. The Worm rod 37 may now be threaded into and through the sleeve 39 and connected at 36 to the operating bar 34 which is in turn connected at its other end at 35 to the link 31.

If desired all of the sections may be provided at the pivot forming corners of their sides with reinforce plates 44 as shown in Figures 1 2, and 8.

It is oi course to be understood that the details of structure and arrangements of parts may be variously changed and modified without departing from the spirit and scope of the invention.
