' Specification of Letters'Patent. Patented 7 Application -fi1ed.,August 3, 1916. 5eria1- 1 Io.'1;12,,95.

To all whom itmay concern Be itr known that 1, Fun. STAEHELIN, a citizen of the United .Statesof America, residing at. 215 v 13.;56th St.,- Chicago, county of Coolg. and .State of Illinois, have invented new and useful Improvements in Awnings, of which thev followingis a specification.

My invention relates toimprovements in awnings and particularly to those in which a portion of ;the fabric is parallel to the window and a. portion is held at an angle thereto when in use. An awning of this type is shownin U. S.-Patent 801421-Walgeret cl.

ln my improved awning, I provide means for operating the device from inside a screen or even inside a window without opening either as all parts are self alining at all times. I obviate the use of allv springs and provide apparatus in which nopockets are formed in which dust and dirt might accumulate to interfere with its proper operation. 'In my .device all braces and arms are suspended from above and therefore cannot project to. interfere with anyone passing under the awnings. Furthermore, in supplying a. device in which .all parts are movably guided,I obviate the danger of any parts leaving their proper alinement during manipulation in case there is any appreciable wind at such time. ;I providean awning which can be adjusted to numerous positions whenin use by a very simple manipulation. ;In; fact, but two operations are necessary to lower itinto position and retain it there.

In the accompanying drawings which form part of this specification; Figure 1 represents the complete awning in place. rolled up Fig. 2 is a side elevation or. certain parts onv an enlargedsscalev at a certain stage in lowering of the awning; Fig. 3 shows the complete awning fully distended and dotted lines illustrate, the releasing action; Fig. ;el is a toplplan view of the fixtures atoneside under the same conditions illustrated in Fig. 3-;Fig. 5 is afront elevation on an en larged scaleof the same parts shown inFig. 2 but adjusted about asthey, appear in, Fig. ,3; Fig. -6 is a side elevation similar tov Fig. 2 but illustrating the completioncfthe release action; Fig. 7 is a.side elevation illusmember 4 which may he a. ropeor cord. ,A-

h o .5 f y suit b Shan ia q ided t fasten the rope when theydeyice is in use.

This hook may be replaced a locking pulley. The,cross-rod .7' which is attached to the window frame acts as a gnide and'support for the" awningfabric. lhe fabri'c. .3 is attached to arod 8 ,lwhich is supported byai'ms 9 pivotally mounted on trnnnionsJQwhieh slide on the guide rods Thescrods are at. tached to thewindow frame 1 inany suitable manner. The'two sides of the awning support frame and, retaining mechanism are Each side has a brace l -l pivotally mounted on the arm}? and is caused. to follow the guide o d 6 by means of thestirrup 12. One .endl flof the stirrup 12 projects through the bracell to act as a stop for thearm 9 at certain times. t h dx thebra he ram 3 c is a tached to the window framein any suitable manner. Thebracket frame 13, guard 1-6 andratchet 15 are of such relative ,pr..0portions. that the pin 14: attached to braoe,11

will enter from above between the guaigd16 and theratchet 15 when the awning is lowered intoits open position, (Fig.2) and will slip out, between. themat. thefbottom whentheawning is being closed (see dotted lines Fig. 8). To accomplish the latter, theguard 16 and theratohetlaare pinotallyattached to thebracket 13 by. the,pin 18. and thr c e 3 is med w hersledd'e 19 which guides the pin ;14;; o.ut. to become fre -0 th lie shs h ratchet '15.;j 3* a part of theframe 13. Then thelguard. 16 only rivote The cord. imam-be attached. .eitherprr the inside of the windowframe or outside.

;When;r1 pt in use-the a,rm,9 .and bracell are folded upward and are raised out of the way when the fabric ,isrolled'pn iroller (Fig. 1)}by. manipulating 'cord 4. In order to open my improvedawning thecigird 4 is Aratchetfrack 15 is pivotally at- V released from thehook 5 and the fabric is unrolled from the roller by the weight of the braces and arms, until thetrunnions 10 have slid to the bottom of theguide rods 6. Thearms 9 then swing out and downward and thepin 1 1 of thestirrup 12 falls between theguard 16 and the ratchet 15 (Fig. 2). henthe awning has reached the position desired the cord t is wound around thehook 5 thus holding thepin 14 in one of the teeth of the ratchet by placing a tension on the fabric. Since thebrace 11 is guided by means of therods 6 andstirrups 12, thepin 1% must enter between the guide and ratchet although a wind may blow under the fabric tending to throw it out of alinement. To fold the awning tension on therope 1 is relieved permitting thearm 9 to fall below 90. This draws the brace down along the ratchet until thepin 1% strikes thebevel portion 19 of thebracket 18. The pin 14- in traveling along the bevel portion causes the ratchet and guard to swing outwardly on thepin 18 so that thepin 14 may pass out at the bottom from between the guard and ratchet which then fall back into place (dotted lines, Fig. 3), the pin I l dropping down upon a shoulder or ledge of the bracket 13 (Fig. 6). The outward swing of the ratchet and guard is limited by abutment of the lower end of the ratchet bar against a shoulder formed by a laterally turned lower portion of thebracket 13, said laterally turnedportion 20 extending inward from said shoulder so as to constitute together with the overhanging portion of the bracket a guide or keeper for the ratchet bar. By pulling on rope i, thearm 9 is caused to swing upward as the fabric is rolled on theroller 2 and thebrace 11 is caused to slide upward on theguides 6. Thepin 1% now passes along the outside of the guard 16 (Fig. 7) because there is sufficient play in the stirrup to permit it. Thearms 9 are raiscdinitil theysi i the projecting pins '17 supplied by the stirrup ends (Fig. 1)

whose purpose is to prevent the arms becoming entirely perpendicular as such position might be a dead center and prevent the free falling of the awning. After thearms 9 have encountered thepins 17, the entire awning is raised out of the way, the trunnions with thearms 9 and braces 11 being slid along theguide rods 6 until the entire awning has beenrolled up.

I claim as new and desire to protect by Letters Patent:
