EI LLSWORTH J. HANNA, OF EVANSTON, ILLINOIS AWNING MECHANISM OR THE LIKE Application filed November 7, 1929.

The present invention relates to barrier or deflector mechanisms for openings and more in particular to movable and adjustable awning mechanisms or the like.

Among the objects of the invention is to provide a novel barrier or deflector mechanism for an opening and having a plurality of pivotally connected vanes or slats being supported and carried by substantially rigid VLU and extensible means.

Another object of the invention is to provide a novel means for supporting the vanes of a barrier or deflector mechanism for openings, this novel means comprising a substan- 97-1 tially rigid and extensible means for support of the ends of the slats or vanes, and being adapted to be collapsible or contracted when not in use and to be extended into any desired position for varying the angularity 2 of the vanes or slats supported thereby.

The invention comprehends the idea of pivotally mounting the extensible means adjacent the sides of the opening and providing suitable means for engagement with the extensible means for movement of the awning or barrier mechanisms outwardly and away from the openingupon a lowering of the same.

Another novel feature of the invention is t the provision of cross members or rods secured to certain parts of the extensible means for preventing lateral movement of these extensible means, these rods adapted to have secured thereto asuitable covering to pro- 5 vide a plurality of vanes for'the barrier or deflecting mechanism.

The invention further comprehends the idea of providing novel pantograph mechanisms for attachment to the sides of the opening, certain of the links of these mechanisms adapted to have attached or secured to the ends thereof, cross members or rods, the adjacent rods or cross members of the same links having a covering secured to the same for providing a plurality of vanes or slats for the barrier or deflector.

Another object ofthe invention is to provide novel means for reinforcing and maintaining the rodsor cross-members between 50 the pantograph mechanisms in alignment,

Serial No. 405,343.

such means comprising strips or the like connected or attached between the adjacent rods of the same link and spaced therealong.

The invention further comprehends the idea of providing a plurality of extensible means or pantograph mechanism secured to or pivotally connected adjacent each side of an opening and carrying therebetween a plurality of vanes or slats, means being provided for raising and lowering these mechanisms simultaneously.

A further object of the invention is to provide a novel arrangement of means for raising and lowering a plurality of extensible means or pantograph mechanisms, the means employed comprising a cable or cables or the like, the same being operatively connected to the pantograph mechanisms and to an equalizer. This novel equalizer arrange ment is provided to vary the ratio or movement between the same and the pantograph mechanisms during certain portions of travel of the latter from a contracted to an extended position and vice versa.

The invention further comprehends the idea of providing a novel constructed means or lever arm for movement of one of the sets of pantograph mechanisms outwardly and away from the opening, this arm being provided with an eye at the end thereof for the threading of a cable or the like for the raising of the mechanism, this arm being further provided at the same end with a notch or the like for engaging extensions on the pantographs for outward movement thereof upon a lowering of the same.

Other objects, advantages, features and capabilities are comprehended by the invention as will later appear, and as are inherently possessed thereby.

Referring to the drawings:

Fig. l is a front view in elevation of a window or opening and showing an embodiment of the invention connected to the sides thereof to provide an awning for the same.

Fig. 2 is a vertical crosssectional view taken in the plane represented by the line 2-2 of Fig. 1 and showing the novel awning mechanism in its raised or contracted position.

graph mechanism and for preventing lateral displacement of the same, could be provided foraccomplishing the same purposes.

Each of these .pantograph mechanisms have at their upper ends lever arms 32, 33 and 34, the arm 33 being pivoted adjacent the end of the end link 35 by means of a rivet or the like, while the lever arms 32 and 34 are provided with apertures registering with an aperture adjacent the end of the link 36 through which extends a rivet or the like for pivotally connecting the same to the link Each of these arms are provided with an aperture at the other end thereof, the arms of the upper pantograph mechanisms 10 and 11 being journaled on a cross member or rod 37 carried by the brackets 12 and 13, while the armsof the lower pantograph mechanisms are j ournaled on the cross member 33 carried by the brackets 16 and 17.

Similar lever arms 39,40 and 41 are provided at the lower ends of these pantograph mechanisms, the lever arms of the lower pantograph mechanisms 14 and 15 being journaled adjacent the ends of a cross member or rod 42 which member or rod has its ends pivotally secured in the lever arms 43 and 44 which in turn are pivotally mounted in brackets 45 and 46 secured to the side members 3 and 4 respectively of the frame 1. The lever arms 39, 40 and 41 of the upper pantograph mechanisms are journaled adjacent the ends of a cross member or red 47, this rod having lateral extensions 48 or having a part extending laterally of these levers to which are connected cables or the like 49 for raising and lowering the awning mechaism (to be later more fully explained), these projections being adapted to engage with the end oi lever arms 50 and 51 pivotally connected to the brackets 16 and 17 on the side members 3 and 4 respectively, when the upper pantograph mechanisms are lowered.

These lever arms 50 and 51 are channel shaped as clearly shown in Fig. 11, the side portions 52 and 53 having arcuate shaped notches 52 at the ends thereof for reception of the extensions 48 of the cross bar 4". The side portion 52 is provided with an extension 54 bent laterally and over the end of the side 53 to provide an eye or opening at the end of the lever for the threading of the cable 49 therethrough. The central or web part 55 is provided with an extension 56 bent back upon the web 55 to providea smooth and rounded surface for passage of the cable 49 thereover.

The lower end of the cable 49 on each side of the opening passes around pulleys 57 or the like mounted on the lever arms 43 and 44 andis anchored by any suitable means to the side members 3 and 4, as clearly shown in the drawings. It will accordingly be seen that upon movement of the upper awning mechanisms, the lower awning mechanism will simultaneously be raised or lowered therewith.

For raising and lowering the upper awning mechanism, cords or cables 58 of substantially equal lengths are provided, these 62 on the side members 3 and 4, thence over H pulleys 63 mounted on the brackets 12 and 13, and then secured or attached to the extensions 48. It is or" course, understood that the cable or cord 49 and 58 may be of t -e same piece, the connection being made to the extensions 48 by way of a loop or the like. A cord or cable 64 is connected to the equalizer block and passes around a locking pulley 65 or the like secured to the rail member6 of the frame 1.

In the operation of the embodiment disclosed, the equalizer 61 is raised or lowered by way of the cord 64 and as shown in Fig. 1 of the drawings, a raising of this equalizer will permit the upper pantograph mechanisms to extend and drop downwardly, the lower mechanism during this operation simultaneously extending and moving angularly away from and outwardly from the opening and in the path of the ends of the lever arms 43 and 44. Upon an extension or dropping of the upper pantograph mechanisms, the extensions 48 will engage with the notch at the ends of the levers 50 and 51 which likewise causes the upper pantograph mechanisms to move outwardly and away from the opening upon a further extension thereof. The angularity of the vanes or slats of these mechanisms will vary depending, of course, upon the extent to which the pantograph mechanisms are extended, as likewise upon the length of the lever arms 50 and 51, 43 and 44. Any desired ratio between the length of the arms 43 and 50 and the arms 44 and 51 may be had.

The equalizer 61 has a double purpose. This equalizer not only provides suitable means for evenly raising and lowering the awning mechanisms, but it will likewise be noted that there is a factor of reduction between the movement of the same and the movement of the cross member 47. WVhile the awning is comparatively light or is in a position such that the greater component of its weight is along the lever arms, the cables 58 will run considerably faster than the movement of the equalizer. This condition exists until the equalizer rises to a point opposit-e to the pulleys 62. From this point until the equalizer rises to its extreme top position, the ratio is reversed and has reached a point where it takes considerable motion of the equalizer to transmit very little motion to the awning mechanism.
