SELF-ADJUSTING FOLDING- ARM FOR AWNINGS,

To all whom it may concern:

Be it known that I, GEORGE BAPTISTE, a citizen of the United States of America, residing at the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Self-Adjusting Folding Arms for Awnings, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to an arm for supporting awnings used upon buildings, and it has for its object the production of an arm of this description which is of folding and adjustable nature, thereby providing for the awning to which the arm is attached being projected to a wide degree with a limited degree of pitch in the awning when it is in its projected and spread position. By the use of an awning supporting arm of this kind, I am enabled to attach the upper portion of the awning at a much lower elevation than that at which awnings are usually attached to buildings, and at the same time provide a greater shade effect in the use of the awning, due to the increased projection thereof. The lower attachment of the awning to the walls of buildings is particularly of importance in instances where windows of buildings, to which awnings are applied, are provided with overhead prism lights which it is not desirable that the awnings should obscure when either in its lowered or elevated positions.

' Figure I is a perspective view of an awning equipped with my supporting arm applied to the wall of a building at the location of a window therein, the awning being shown in spread position. Fig. II is a similar view to Fig. I with the awning shown in elevated or folded position. Fig. III is an enlarged side elevation of my awning supporting arm shown attached to the wall of a building with the awning shown in elevated or folded posi tion in dotted linesf Fig. IV is a top or plan View of the supporting arm.

In the accompanying drawings, I have shown an awning equipped with my supporting arm applied to the wall A of a building to furnishshade for a window B in said wall. The window shown is provided at its top with a prism light (I.

D is an awning cover which, as shown in the drawings, is attached at its upper end to the wall of the building or the window at E and beneath the prism light C.

Referring now to my awning supporting Specification of Letters Patent.

Application filed March 6, 1908.

Serial No. 119,432.

arm of which two are preferably used in connection with each awning, which belng duphcates of each other, need not be separately described, as a description of one of them 1;

will apply to the other. 1 is a lower bracket, and 2 an upper bracket adapted to be secured by suitable means to the wall of a building, or the frame of awindow situated in said wall.

4 is a guide rod mounted in a vertical position in sockets in the brackets 1 and 2 and spaced by said brackets from the wall of the building or window frame.

5 is a sleeve slidably fitted to the guide rod 4 and provided with an ear 6.

7 is an inner projecting bar pivoted at its rear end to the ear 6 of the slide 5 and to the outer end of which is pivoted at 8 a link 9 preferably consisting of two members as seen in Fig. IV. 10 is a second projecting bar consisting of two members that cross the projecting bar 7 and is pivoted intermediate of its ends at 11 to the projecting bar 7 intermediate of the ends of said last named proj ecting bar. The projecting bar 10 is pivotally connected at its rear end at 12 to a slotted supporting link 18 that is pivoted at 14 to an ear 3 forming a part of the upper bracket 2.

15 is an extension bar to the outer end of which the awning cover is attached, this extension bar receiving the pivotal connection of the link 9 at 1,6 and the pivotal connection of the projecting )ar 10 at 17.

In the practical use of my awning supporting arm, the arm is, when the awning is in ele vated position, folded compactly as seen in full lines Fig. II and dotted lines Fig. III at which time its sleeve 5 is located at the lower end of the guide rod 4. At this time, the extension bar 15 of the supporting arm is in the folded condition of the arm so located that its inner end occupies a position adjacent to the lowered sleeve 5. IV hen the awning is lowered, the extension arm 15 swings outwardly from its upright position and carries the awning cover, and as it so moves it acts, by a downward and forward pull, upon the link 9 inner bar pivoted to the sleeve-ear, an outer bar, a supporting link pivoted to the upper bracket-ear, an inner oross-bar pivoted to the inner bar, to the outer bar and to the supporting link, and an outer link pivoted to the inner bar and to the outer bar.
