Specification of Letters Patent.

Patented Feb. 2%, ll,

Application filed March it, 1917. Serial No. 154,785.

primary object of the invention is the pro- VlSlOIl of an awning so constructed as to shielda window from the direct rays of the sun, but obstruct as little as possible dili'used light entering the window, and permitting free circulation of air,

Awnings as ordinarily constructed are objectionable in that they obstruct the light even when raised, and that when lowered they not only obstruct the light and obstruct the free entrance of fresh air and the outlet of foul air, but that a pocket is formed in the upper portion of the awning which retains hot air and prevents the free egress of warm air from the room if the upper sash is open.

As before stated, the primary'object of the invention is to obviate this difiiculty by the provision of an awning so constructed as to permit the entrance of light and air, and a further object is to so construct the awning that there will be provided a plurality of awning sections "which may be lowered so as to take a stepped but parallel spaced relation or may he raised up entirely out of the way ofthe window, the spaces betweenthe awning sections when the awning is lowered, permitting free ingress and egress of air and acting to permit the entrance of diffused light while preventing the direct rays of the sun from entering.

A. further object of the invention is to provide a very simple awning of this char,

acter which may be cheaply made, readily installed, and may be easily raised and lowered.

Still another object ofthe invention is to provide, in connection with an awning of this character an awning frame so constructed that it may be readily appliedjzo, window casings or jambs of ordinary w1ndows.

Still another object is to so construct the awning that it may be thoroughly braced, against the action of wind, and another ob.

ject is to provide a form of awning which will also act as a shelter from rain and sun, and particularly adapted for use in windows facing south.

Other ob ects will appear in the course of the following description. My invention is illustrated in the accompanying drawings, wherein: I

Referring to Figs. 1 and 2, A designates the window casing of a building defining the usual window opening. The awning frame in these figures comprises a pair of laterally spaced parallel lazy tongs, designated gener ally 2. Each lazy tong comprises a plurality of members 3, l, 5 and 6, which, when the awning is lowered, extend outward horizontally with relation to the vertical wall of the building and have a stepped parallel relation, and a plurality of members 7, 8, 9 and 10, which, when the awning is lowered, extend in vertical lation.

The members 3 and 6 are each pivotally mounted upon the window frame for vertical movement in a manner which will be later described. The members 7 and 10 are pivoted each to two of the members 3, l, 5 and 6, and the members 8 and 9 are pivoted each to three of the members 3, 4, 5 and 6.

planes and in stepped re- I i This is the usual construction of, lazy tongs,

and the lazy tongs 2 differ therefrom only in the fact that the members 7, 8, 9 and 10 ,each extend beyond their pivotal connections to the coacting members'3, 4, 5 and 6. Thls be seen -fromFig. 1 that when the awning registration with eac is raised, however, these several awning sections, together with their supporting members 7, 8, 9 and 10, will be disposed in parallel vertical relation but aproximately in 11 other but close together and against the wall of the building. When, however, the awning is lowered, the several awning sections will extend succes- Sively one below the other to any desired extent. I

In order to hold the lazy tongs in their lowered position against upward pressure, I provide, preferably, the rule jointed braces 13, each brace being pivotedat its lower end to one of the members 6 and at its upper end to the frame of the window or the supporting frame of the lazy tongs. To prevent the lazy tong from opening farther than the position shown in Fig. 1, I provide the chains 14, each connected at one end to the lower-end of the member 7 and at its other end to the member 8. For the purpose of raising or lowering the awning I may cone nect any one of the horizontal members, as for instance the members 3, to cords 15-passing over suitable pulleys, and operatively mounted to swing the awning from a lowered position to a raised position. For the purpose of pivotally connecting one set of members of lazy tongs to the other set I preferably provide the special form of rivets illustrated in Fig. 5, these rivets being designated 16 and provided with a middle flange 17 adapted to be disposed between two intersecting members and forming the pivots therefor. Preferably, all of the members are formed of channel iron, though I do not wish to limit myself to this.

In Fig. 2, I show another form of my invention wherein the awning sections, when the awning is lowered, are disposed in hOllzontal planes but in a stepped spaced rela-- tion. In this form of my invention I provide a pair of oppositely disposed lazy tongs,

designated generally 18, each pair, consistingof lazy tong members 19, 20, 21 and 22, which, when the awning is lowered, are disposed in horizontal planes and in stepped relation, andaplurality of members 23, 24,

25 and 26ipivoted to-the members 19,20, 21 and 22, and which, when the awning is lowered, are disposed in vertical planes and in stepped relation. The members 19, 20, 21 and 22 are pivoted to the members 23, 24, 25 and 26 in the same manner as previously described.

Attached in any suitable manner to the members 19, 20, 21 and 22 are the awning sections 27 The members 19, 20, 21 and 22 are of such length that the awning sections, when the awning is lowered, overlap each other so as to prevent the slanting rays of the sun from striking downward through the space between the awning sections. The upper members 19 of the lazy tongs are pivotally mounted upon the window for movement in a vertical plane, as are the lower members 22, and the awning isheld in its lower position against wind pressure by means of the rule joint braces 28 pivoted at their lower ends to the members 22 and at the upper ends to the frame of the window or supporting frame, previously described. The awning is held from opening farther than indicated in the drawings by means of the chains 29, each attached to the lower end of the member 26 and to the lower end of a member 25. The awning is raised or lowered by'means of a cord and pulley, as shown in Fig. 1, previously described. The members of the lazy tongs are preferably of channel iron and held together by the rivets as illustrated in Fig. 4.

The advantages of my invention are plainly evident from the drawings. The construction shown in Figs. 1 and 3 is especially designed for situations facing east or west, where the sun in the morning and evening is near the horizon, and as a consequence the direct rays of the sun will extend approximately horizontally into the window. The construction shown in Fig. 2 is particularly adapted for southern exposures where the sun will not strike into a window until it has attained considerable altitude. In both of these forms of my invention there is practically free ingress and egress of air, and plenty of diffused light is admitted, without, however, admittin the direct rays of the sun. It will be note also, with reference to the construction shown in Fig. 1, that the members 7, 8, 9 and 10, with their awning sections, may be partly raised or lowered without changing the vertical relation of theawning sections, and without obstructingthe upper part of the window. lVhile I do not wish to be limited to any particular means for supporting the awning I have illustrated in Figs. 1 and 2 a set of irons which may be readily applied to the window jambs or casing --of a window. These irons comprise two parallel sections of iron pipe, indicated 30. Each of these sections 30is.bowed inward at 31 and flattened, this flattened portion being perforated for the passage of screws 32 which will ennearest ter the wood of the window frame. The upper and lower ends of these ipe sections are bifurcated, as at 33, for t e reception of the upper and lower supporting members of the lazy tongs.

By deflectin the middle portions of the pipe sections t e end portions will be carried outward beyond the outer face of the building, and the pipe sections are braced apart by means of a bracing section 34. In Fig. 8 li show another form of the same construction in which oppositely disposed tubular or pipe sections 35 are provided, the middle portion of each section being bowed or deflected, as at 36, and laterally flattened, the ends of each pipe section being bifurcated asat 37 for the pivotal engagement with the supporting members of the awning. The upper ends of these pipe sections are connected by means of a transverse brace section 38, and the pipe sections may be forced apart by means of the transversely extending braces formed by pipes and designated 39. These have reverse screw threads at the ends to engage with bosses formed upon the pipe sections 35, and byrotating these braces 39 in one direction the pipe sections 35 may be forced apart and set against brick or stone work, holding the supporting frame or brackets rigidly 1n position. Of course, I do not wish to be limited to this particular supporting frame, as it is obvious that many other forms might be provided.

Having thus described my invention, what ll claim is:

In an awning, the combination of a vertical supporting body, a pair of lazy tongs comprising a series of parallel members ex= tending vertically and a series of parallel members extending horizontally, certain members of which are swingingly secured to the supporting body, said vertical members being pivoted to the horizontal and extending above the pivot points, means fastened thereto to exclude the direct rays of the sun, and means for limiting the spread of the lazy tongues.
