Application filed July to, 1917".

To all whom it may concern Be it known that T, ROBERT E. Hnonns, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Awning-Supports, of which the following is a specification.

The present invention has to do with that type of foldable awning support disclosed in my previous Patent No. 1,217,765, granted February 27, 1917, these improvements being more particularly directed to the locking means by which the jointed sections of the awning arm are held in extended position.

T as hereinafter more fully described, claimed and illustrated in the accompanying drawings, wherein:

ltigure 1 is a side elevation of the awning arm in extended position, showing the awning pole and material in section;

Fig. 2 is a front elevation, the arm being folded into inoperative position;

Fig. 3 is a fragmentary view of the elbow portion of the arm;

Fig. 4- is a horizontal sectional view on the line 1-4 of Fig. 8; and

Figs. 5 and 6 are fragmentary side and top plan views of the inner supporting extremity of the arm.

Tn the drawings, 1 designates the Wall braclret to which the connecting piece 2 is pivotally connected by the horizontal bolt 8. The piece 2 is arranged and constructed so as to be adjusted in a vertical plane as by means of the set screw 5, such adjustment controlling the inclination of the awning arm which is connected to said piece by the pivot bolt 4 for swinging in a horizontal plane.

The arm comprises the inner section 6 and the outer section l, the latter having connected thereto the awning pole 8 over which the awning material 9 drops. It will be ob served that the arm sections are made up of T-shaped iron held in spaced relation by the connecting plates 10. This gives a lighter specification of Letters Patent.

construction than when the I-beam form of material is employed.

The sections 6 and 7 are joined by means of the pivot 11 about which is arranged the spring 1'2. Said spring has a tendency to unfold the sections from their inoperative posi tion when the awning is unrolled in the usual manner and while the peculiar inclination of the arm has this same tendency, the action is much more positive.

The special feature of this invention is the form of locking means employed. As will be observed by reference to Fig. at especially, upon the inner section 7 of the arm, ll mount a locking bolt 13 which is preferably spring actuated, the said bolt being arranged transversely of the arm. To the end of said bolt is connected one end of a bell crank lever 1d pivoted adjacent thereto and this member has in turn connected thereto a cable or other pull member 15 by means of which latter the bolt may be retracted for the purpose of releasing the joint to permit of folding movement. The bolt 13 engages with the contiguous end of the outer arm, or more strictly speaking with an extension plate 16 provided thereon. This plate is bent at an angle laterally and then back at its free ea:- tremity and upon extension of the arm sections the said plate acts as a limiting stop by virtue of its impingement with the adjacent end of the inner section. The extremity of the plate is suitably beveled and apertured so that the bolt 13 will positively engage therewith and hold the sections in their eittended position. The particular arrange ment of the bolt 13 transversely of the arm section is important owing to the consider able stress which is imparted to these supports by wind pressure. llt will be apparent that the likelihood of the extension plate being bent or broken from its riveted fastening is remote because the stress is transmitted through the bolt in a direction longitudinal of the arm.

The bolt 13 is considerably reinforced by the thickness of the metal at the point where it is mounted and the bolt is also safe against forcing from its mounting.

Having thus described my invention, what is claimed as new is 1. An awning arm of the class described comprising jointed sections, and locking means for holding the sections in extended position comprising a bolt transversely arranged on one of said sections and engage able with the contiguous end of the other section, stress being transmitted transversely of the bolt and longitudinally of the arm whereby to prevent bending of the parts.

2. An awning arm of the class described comprising jointed sections, and locking means for "holding the sections in extended position comprising a bolt transversely arranged on one of said sections, the cont-iguous end of the othersection having an-extension constituting a stop for limiting relative movement of the sections with which thezbolt'isengageable, and a lever connected to the bolt for retracting the bolt to permit of folding operation of the arm.

3. An awning arm of the class described comprising jointed sections, and locking means for holding the sections in extended position comprising a bolt transversely an ranged on one of said sections and engageable with the contiguous end of the other section, a bell crank lever connected to the bolt for actuating the same, and a manually operable connection for said lever.

In testimony whereof I aliix mv signature.
