These ,bracketsare arrangedto supnism utilizing P r hich are devoid of port the roller 15 outwardly beyond the a sharp corners or protruding edges likely to brackets 18 which ares'ecured lowerdown on 50 tean theawqning which willaid in preopposite sides ot-theirame l0 and provide 1 pivotal mounting for the lower ends of the rigid arms 19, the upper ends of which are integrally connected by a cross piece run through a hem in the awning adjacent the free edge of the latter.

Inasmuch as the pivots 21 for these arms are arranged inwardly of the rolled awning the cross piece 20 strikes the roll before the arms 19 can be swung to a verticalor. dead center position. Thus the weight of these arms always acts to unroll the awning and move it toward its fully extended operative position.

The roller 15 is preferably a hollow metal tube having a plug 22 in one end thereof carrying a gudgeon 23 adapted to be dropped into a slot 24 in the bracket 16. The plug may be pinned in the hollow roller by a screw 24.

Bracket 16 includes the plate portion 16* disposed in a vertical plane and projecting outwardly from the window frame and the integral horizontal plat-e portion 16 secured against the underface of the top of the window frame.

The other roller supporting bracket 17 includes an attaching plate portion 17 lying against the top of the window frame and a. pair of spaced forwardly projecting parallel plates 17 integrally connected at their ends and providing mountings for a train of intermeshing operating gears 25, 26, 27 Gear 27, the driven gear of the train, is preferably the largest one and its axle 28 projects well inwardly and mounts a hub 29 for the open end of roller 15. This roller at its open end is provided with diametrically opposed notches 30 receiving the radially projecting ends of a pin 31 passed through the hub 29 and holding this hub in place on the axle 28. The slot and pin connection 30, 31 couples the roller 15 and hub 29 for unitary rotary movement. It also permits the roller 15 to be readily emplaced and removed, removal being accomplished by merely lifting the gudgeon 23 out of its notch 24 and withdrawing the roller endwise from the hub 29.

The driving gear 25 which imparts movement to the driven gear 27 through a small idler 26 is also provided with an extended axle 32 mounting a hub 33 corresponding to 'thehub 29 and provided with a pin 34 similar to the pin-31.

The hollow horizontal driving shaft 35 is mounted between the roller 15 and the sash 1.1 in substantial parallelism with the roller. One end of the shaft is notched at 36 to slip over the hub 33 and engage the ends of pit 34. A plug 37 is secured by screw 37 in the opposite end of shaft 35 and carries a grid-- geon 38 mounted in the depending portion 39 of a bracket 39 fixed to the top of the window frame at approximately the center thereof. A sprocket wheel 40 is'held on the outer end of the gudgeon 38 by pin 41. i

The endless flexible device 13 (in this case a sprocket chain) for rotating the wheel 40 passes from this wheel through an adjacent opening 42 in the upright 12, over the sprocket 43, mounted in a bracket 43 secured to the inside of the upright 12. The sprocket chain extends downward within the room near the lower end of the window around sprocket 44 .andout through the opening 45 over sprocket therein, within which the ends of tubular inner and outer flexible concentric sleeves 50, 51 are secured. Sleeve is preferably of leather or some similar tough long-wearing material adapted to withstand frequent frictional engagement with the ch ain, while sleeve 51 may be of velvet or other soft material which will serve as a cushion and grip for the hand and at the same time present an ornamental appearance.

g The operation of the device is substantially as follows: To shift the chain in a direction to unroll the awning, the sleeve 47 is grasped tightly and raised, carrying the chain 13 with it. The sleeve is then released and slid down to its normal position after which the operation is repeated as manytimes as necessary. reverse operation is of course resorted to in rolling up the awning; that is to say the sleeve is slid up on the chain and then it is grasped and pulled down car rying the chain with it.

In this operation the sleeve 47, which is normally capable of sliding freely on the chain, moves with the chain only because it is frictionally engaged therewith by the pressure of an operators hand. It will be understood, of course, that the movement/of the sprocket chain turns the shaft 35 and through the gears 25., 26,27rotates the awning roller 15 to positively roll up the awning orto permit the awningto unwind under the influence of the weight of the bar 20 and its arms 19.

Due to the powerful leverage afforded by the sprocket chain and gear-train, raising or lowering of the awning requires the application of only a slight physical force and 1 conveniently placed employ; the small n mes the awning, however,- particularly where the awning isa very.wide,heavyone, some phys ical exertionisnecessary, even with the powerful leverage, which the, present mechanism affords. Since the manually applied force incidental to raisingthe awning may be more by a downwardpull than by an upward-lift, reversing idler gear 26 n {the geartrain, By virtue of this arrange .ment, the person operating the awning may conveniently utilize their entire weight, if desired, topull down-on the chain, whereas theapplication of an upward lift on the chain cannotbe aided by the weight of the body.

. :The friction of the gear. train and the sprocket-chain isordina-rily sufficient to balance the weight of thearnis l9 and cross piece 20,so that the chain against moving.

the awning is retained against enrolling from any position of adjustment. If desired however, an additional positivesafeguard may be provided to secure This means-may conveniently comprise a chain keeper fixed to theinner faceof the bar 12. p This keeper includes attaching :plate portion 52 screwedor otherwise secured asat 53 to the viii baril 2and at itsupperedge providedwith horizontalextension 54: having :a keeper slot- 55 extending inwardly from ,one edge thereof, 1 The sprocl ietchain is of conventional light wire construction.

tlieinner run of the chain is-fleXed inwardly and the chain link engaged inthe slot-55' the chain will be securely. held ,since. the eyes or enlargedendsmf the links cannotbe pulled through: the slot. r 1 ByJso arranging the, mechanism that the sprocket chain-runs through the center frame bar 12, 1; eliminate any possible-interference of the chain with curtains or draperies such as arecommonlyemployed at the sides of the window. j I i.
