SPBCI EIfiA'iI ONfonning part of Letters Patent No. 363,548,.dated May 24, 1987'.

Application filed March 1 6, 1887. Serlal No. 2313167, (No model.)

To an whom. it 'ma'y ooztcerm.

Be it known that I, HENRYW. Sonwncnn'm 'DIEK, of the city of Baltimore and State of Maryland, have --inve'nted ments in Awnings, of which the following" is a specification.

v y invention has reference-more particularly to that class of store-awnings in which the awning-sheet is attached at its upper edge A to a winding-roll and carried at its lower edge by,a.bar on the outer end of arms jointed to the building to swing vertically; 1

The aims of the invention are mainly to provide means for-automatically locking the awn ing when extended, so that it may not be lifted' by the wind, and to admit of the awning being extended a greater or less ,distance, as the circumstances require.

In the accompanying drawings,- Figures 1, 2, and 3 are sectional elevations of my a'wning applied to a building, showing the different positions which it assumes. Fig. 4 is a crosssection on the line 1 1, Fig. 2. Fig. 5- is a cross section of the device in modified form. Fig.6 is a longitudinal section on the line 3 3 of Fig. 4. Fig. 7 is ascction on the line 5 5 of Fig. 6. Fig. 8 is a horizontal section on the line 6 6 of Figs. 9 and,12. Fig. 9 is a vertical section on the line 44 of Figs. 8 and 12. Figs. 10 and 11 are-side elevations showing the awn ing-frame inmojdified forms; Fig. 12is'a sectional elevation showing the winding devices in their preferred form.

Referring to Figsfi 1, 2, 3,. 4;, 6, 7, and 12, A represents a horizontal windi'ng roll, fixed in any suitable support at' the front of the building and combined with means of any suitable character to effect its rotation. 1

B B'repre'sent the awningsheet, attached at its upper edge to-the-winding-roll and at its g I a, 031'- ried at the outer ends of arms 0, which arms are inner ends to the building'or other fixed support at b, so that-- they may swing vertically. When the sheet is wound lower or outer edge toahorizontal bar,

be shortened to. admit ofthe this telescopic or extended :jected or extended position, 3' show it in its inner or retracted position.

upright For the purpose of holding the arm down, solthat. the awning may not be lifted by the action of th'e'wind thereunder, I combine with the arm 0 a brace, D, having one end pivoted to the wall or other support at h, below the.

pivot of the arm (3, and the opposite end con! nected to the arm Gin anymanner which will admit ofits sliding thereon. U

[commonly pivot the arm or brace D to a collar, E, which encircles and is arranged to slide freely on the body-0f arm 0, and in this collar I mount, as shown'in Fig. 6, a springactuated bolt, g, having shoulders g, which enter notches g in the arm 0, so as to lock the brace to the arniand thus hold the awning .secure'ly in its extendedposition. Ialso mount in the sleeve a. leye'r, n, engaging at onei 'end in the'bo'lt and connected at the opposite end to a cord or wire, 0, which is extended through the brace D or otherwise to'a point near the where it may be conveniently grasped by the operator for th'epurpose of unlocking theholt, in order that the awning may be folded-upward.

c When the awning is to extend but a few feet from the building," the arm G is made in one rigid piece from end to end, as shown in Fig.

10;,but when'it is ing of great width arm 0 of two parts reqiiired to'have the awn I prefer to construct the arranged to slide one in relati'on to .theoth'e'ryso that when in use the'a'rm andthat when folded it may parts closing into more compact form. In Figs. 1, 2, 3", 4, and 6 arm consists of the tubular portion d, hinged tothe building, and of the outer portion orrod, 6, arranged toslide therein.

may be extended,

whileFigs; 2 and In order .thattheparts e may be automatically projected as the awning is extended,- I commonly provide the tubular portion d with.

Fig. 1 shows'thfe portion'einits proa longitudinal slot and extend the locking s bolt 9 upward through. this slot into engage nie'nt withfthe sliding members, as shown in Fig. 6. When, therefore, the" arm Oswings downward, the bolt-carried-ohtward by the sliding end of the brace D acts to force thero'd e outward. When the parts reach their'outer most position,

the bolt automatically locks double purpose of locking the part in its extended position and of locking the part 0 against a rising movement. When it-is required to extend the awni 1g 2. moderate distance beyond the building, the-bolt y will be unlocked from the rod e before the awning is extended, and, as a consequence, the arm e will remain in its inner or retracted position, as shown in Fig. 2.

If desired, the brace D maybe pivoted rigidly to an ear on the under side of the rod,

e, as shown in Fig. 5; but in such case the awning will always be extended to'its full width when brought to an operative position.

The advantage of connecting the brace Dto the part e in a detachable manner lies in the fact that it enables the awning to be extended a greater or less distance at the'willof the attendant. V

Instead ofconstructingthe arm 0 in the telescopic manner before referred to, it may be made of two parts or bars laid side by side and connected by .clasps or slides f, as shown in Fig. 11. r

The winding-roll may-be operated, asin -Fig. 1, ,by a sprocket-wheel, G, mounted thereonand connected by a chain, H, to a wheel, I, mounted in a supporting-box on the front of the building,and provided with 'an operating-crank, K. When the. front is of such form as to forbid the direct extension of the chain to the operating-wheel, the construction shown in Fig. 12 "may be adopted. In this figure the chain is extended from the pulley G directly through the wall of the building to an internal pulley, M, the shaft of which, mounted in fixed'bearings, carries a second pulley,

i is extended downward inside the building to the operating-pulley I, which is; in all respects identical with that before referred to.-

. In'order to prevent the accidental or mischievous release of the awning, I mount in the box J a sliding bolt, L, adapted to engage the .chain at one end and provided with a projection, 12, or its equivalent, by which it may be moved. v

It is to be understood that the essence of my invention resides in connecting the arm 0 to the brace D by asliding connection and a looking device, within the range of mechanical skill without departing from my invention, the details of the slide and locking device being of minor importance. 7

combination with the brace Having thus described my invention, what I claim isv 1. In an awning-frame, the extensible arm 0, hinged to swing upward'and downward, in D, pivoted to a fixed support and to the sliding member of the arm 0, substantially as described,whereby;

2. In an awning, winding-roll, the awning-sheet attached thereto, the extensible arm 0, pivoted at one end to a fixed support and connected at .the opposite end to the outer edge of the awning-sheet, and

the brace D, pivoted atone end to afixed support and at the opposite end to the extensible portion of the arm 0.

' 3. In an awning-frame, the extensible arm 0, hinged at one end, in combination with the arm D, pivoted at one end and connected at the opposite end to the extensible member of the arm 0 by a locking device, substantially as shown, adapted to permit its disconnection and shortening of the arm (I the combination of the.

from said sliding member, substantially as-and for the purpose described. I

4. In an awning, the tubular slotted arm 11,

hinged at one end, in combination with the rod e, arranged to slide therein, the collar E, loosely encircling the tubular arm, its lockingboltadapted to engage the sliding rod, and the arm D, hinged at one end to a fixed support and jointed at the opposite end to the collar E, substantially as described.

5. In an awning, in combination with the hinged extensible arm 0, composed of the members d e, the arm D, pivoted at one end to a fixed supportand at the opposite end to a slide or collar, E, a locking device for connecting the slide with the member 0, and a wire or operating device extending through or along the arm D to its lower end, substantially as described.

j 6. In an awning, in combination with the winding-roll and its pulley, the operatingchain, the pulley I, to operate said chain, its supporting case or frame, and the movable bolt mounted in'said frame and adapted to engage the chain. r 1

7. In-an awning, a vertical swinging arm jointed at its inner end to the building or other support and connected at its outer end to the awning, in combination with the brace pivoted at one end to a fixed support and having a sliding connection at the opposite end with the arm, and a catch or-locking device adapted to fasten the brace to the arm when thetwo are extended.

8. The hinged extensible arm d e and the hinged brace having a sliding connection with the part d, in combination with the locking device serving to connect the brace with both theparts d and e, whereby the brace is caused to hold the arm in its extended condition, and down whether extended or not.
