AWNING FIXTURE Patented June 9, 1931 JOHN W. SHAW, or NoRwoon,

AWNING FIXTURE Application filed May 24,

My present invention is concerned primarily with awnings, more especially with those of the spring roller type, and relates particularly to operating means therefor by which the awning may be adjusted from the inside of 'a room without opening the window.

An object of the invention is to provide adevice of the character noted above, which is may be "interchangeably used'with various types of spring roller awnings and which is universally applicable to a wide range of window sizes and window styles, both of the drop sash and of the fixed sash types of window. x v

The usual spring roller awnings embody in the rollers a ratchet mechanism which is more or less flimsy, and (which is so exposed to the weather that it may quickly become rusty and ineffective. In consequence when the awning, 'in partiallyor fully lowered position is blown about by the wind, this ratchet mechanism is sometimes released or broken, and the awning rolls up with a snap and abang,-frequently damaging both the awning and its supporting fixtures and making a most disconcerting noise. V It is accordingly an object of the invention to provide an awning operating means of the above type, in which the flapping or undesired release of the holding mechanism is recluded and which mechanism jyet reac ily responds to the usual manual opera tion to raise or lowerthe awning.

Another object is to provide a substantially fool proof operating mechanism adapted to withstand hard usage and so designed that its carelessmanipulation cannot 40 result in damage to either the awning or the operating gear. 7 7

According to my invention the operating tape is provided with an automatic check arranged in protected position out of' the weather, preferablywithin the room, and

which may serve either to supplement the roller ratchet mechanism or as a substitute therefor. j

The check normally prevents spring-roller urged movement of thetape. A; slight man- 1925. Serial in). 280,150.

however, 'suflices to disengage it from the check so that it may run freely outward as thespringroller winds up the awning.

The tape passes over guides on bracket fixtures arranged adjacent the top ofthe sash and on opposite sides thereof, oneof these fixture'sialso carrying the tape check. These brackets are preferably each made of apair of relatively slidable parts so that they may be arranged to fit any-standard type of sash throughwhich the tape. is to be guided. I Another objectis to provide a mechanism withwhich the above noted advantages are had without sacrificing any of the merig toriou's features and noteworthy advantages of the .awnlng'operatlng means disclosed in myprior application Serial No. 171088. filed present invention Feb. 26, 1927, on which the is an improvement.

Other objects of the invention are to videa mechanism-ofsiinple practical construction which maybe conveniently? {attached to a window, which willbe rugged,

durable and efficient in'use and which is Well suited to the requirements of economical manufacture.

VVlth the above noted and other. objects in View, the invention consists in certain novel features of construction and combina tions and arrangements of parts which will be more fully hereinafter described and c pointed outin the claims. c The invention may be more fully understood from the following description in connection with the accompanying drawings wherein: Y

c Fig. 1 is a perspective view showing the outside of a window equipped with an awn- 1 ing (shown partly lowered). and adapted to be operated by the mechanism of the present inventioni r 1 i v Fig. 2 is a view on a. larger scale in vertical section taken approximately on the line. 22 of Fig. 1." r

Fig. 3. is asectional plan view taken ap-. proximately on the staggered line 3----3 of Fig.2..

Fig. 4 is a vertical sectional detail taken.

approximatelyon the line of. Fig. 2.

' Fig. 5 is a vertical sectional view onthe line 55 of Fig. 3. v

Fig. 6 is a View similar'to Fig. 2 but showing the operating-mechanism applied to anothertype 0f. sash and showing the. operating flexible 'devicedrawn to a posiends of the roller being mounted in conventional hangar brackets 15, 16 secured to the 7 top of .the window frame 10 exteriorly of the sash 11, the latter bracket having the usual slot for the fiat gudgeon.

fA cross bar passingthrough ahem 18 near the free end of the awning isformed Y integral with a pair of arms 19, the ends ciated crossbar tends to unroll the awning 'of which are pivoted to brackets 20 secured Y to the uprights of the window frame'lO,

The. Weight of the arms 19 and their assowhile the coiled torsional spring 2l'secured within the roller 12 tends to roll up the awning. This spring is strong enough to normally overcome the welght of the arms and cross bar; In order to lower the awning, -a -positive unwinding torque must be applied to the roller. and suitable ratchet mechanism 48 serves to block the; rewinding action of the spring 21. As islthe common practice the spring21 is wound about the usual metal core 46 to the hub 47 of the flat 0 gudgeon 14. V

The means for unwinding the awning 17 against the actionof the spring 21 includes the usual-flexible device 32 preferably in the nature of ,atape, one end of which is rolled about the roller 12 between the convolutions of the awning andanchored with theetlges of the awning to theroller by the anchoring.

" notch 33.

' The mechanism thus far described taken byitself is not my invention, the latter being more particularly concerned with the provisionof the tape checking mechanism for positively preventing inadvertent spring winding of the awning and the construction of the brackets 6 0 and 7 O which renders them. universally adjustable. i

The fiexibletape 32 passes through'a slot 7 137 at the upper edge of the window pane shown of the fixed sash type and'depends intorthe'room terminating in a handle loop 7 g Arranged at the outside and inside of the sash are tape guiding brackets 60 and the details of'which'will be later described.

These brackets mount rollers such as. the

' portion 28.

rollers 35, '36 of the outer bracket and the roller 38 of the inner bracket for guiding the tape. The inner bracket also carries my improved checking means which will be more fully described.

The brackets 60 'and70-may be generally similar to'those disclosed in my copending application above identified in that they include attaching portions 22 and 27 respec 'tively and flanged channel forming portions 24- and 30 respectively. within which the guide rollers are mounted. These channel portions are disposed closely adjacent the window pane and facing each other at opposite sides of the sash.

- An improvement. over myf prior disclosure however is the manner in which the brackets 60 and 70 are rendered universally adjust- V able to lit-various sizes and "styles of windows; The channel portion 24 of the bracket 60 is'adjustabl'e along vertical slot 26 in the depending plate portion 23, this adjustment being'eifected by headedscrews V g 25 'working through the slot and engaging the channel piece. Asimilar adjustment of the channel piece 31 maybe effected by adjusting screws provided in channel piece 30 to work through slot 29 in the coacting The present brackets are also similar to those disclosed in my copending. applicationin that both brackets are provided with tape guide rollers 36'and38 near their tops which guide the travel of the tape through the slot 37 in the window pane. Also the channel piece 24 is preferably of greater length than the channel piecev30 and'mounts a guide roller 35 well below: the plane of the; upper rollers 36, 38. Thus as the tape 32 from. the roller 12 is led through the openingv 34 in the back of the channel'24 and passed around under theroller. 35 a down pull is exerted on the spring'roller 12 which is thus effectively 1 prevented from jumping out of its brackets.

.VVhile the adjustable nature of the bracket fixtures herein illustrated is desirablefor renderingthem universally applicable to several styles of sashes,-it is obviously within the scope of the invention to make such brackets as integral one piece stampingsor castings when turned out in large quantities for standard size windows. 7

1 The tape checking means is arranged withthe guide roller 38 This means may include a knurled ecce'ntric39 hanging freely on a pivot pin 40 connecting the flanges of the channel" 30. This eccentric is 'prefer-,

ably provided with a spur 49 near its lower,

end. The bail 41' pendent from the member 30 is preferably provided with a heavyroller 42 on its crossbar. Thisbail normallytendstomove the'handle end of the tape 32 to ,a position closely adjacent the in the channel 30 of the bracket70 below 1 neoaaaa window pane andito hold. the tape in. fric; tional' engagement \Yithpthe. eccentric; '39. The tape is. led around the roller 3'8 between the eccentric 391 and the backgofj the channel 30 and thencaforwardly through the bail 41. v

eccentric sihcethe tape, is always moved into engagement with said spur bytheaction of the roller 42in its inward! swing toward the window'pane.

'YVhen it is desired to permit the, spring roller to wind. up theuawning, the endzof the tape is grasped and drawn rearward or downward, thereby swinging the roller. 43

well rearwardl'y and. disengaging the tape from the spur 49 of the eccentric 39. As long as the inner end of the tape is manually held from returning to the position of. Eig. 2,, the tape may run. freely in an outward direction without any interference; from the eccentric,

It may be noted that the action of the eccentric and its associated tape engagingmechanism is. entirely independent of the usual pawl, and ratchet. mechanism of! the roller and is much morepositive in operation than such mechanism. The tape engaging means dispenses with the need for conven' tional' ratchet and pawl mechanism and the simplified spring roller of Fig. 7 devoid of ratchet mechanism may be conveniently used. The parts of 7 bear the same reference numerals as the corresponding parts of Fig. 8'. 7

Even though. the awning is in fully or partially lowered position and is being blown about by the wind" in a manner in which would render the ordinary ratchet and pawl mechanism of the roller inefi ec tive, there is no. danger of theeccentr-ic tape retarding means failing to function, and there is no danger of the-spring roller being gentially to the roller.

released to wind; up the, awning with an undue rapidity which might injure the mechanism.

InFig. 2 it will phenoted-that the channel members 24, 30 are disposed as closely as possible to the window pane and that their upper. edges abut the lower face of the upper-cross bar 50 of the fixed sash 11. In Fig.6, however, the channel pieces 24 and 30 are so adjustedv that they abut the win dow framelO immediately adjacent the in ner and outer faces of the upper cross bar 51 of a sliding sash. Here the tape passes through a notch 52in the top of the cross bar 51 so-that it willnot interfere with the usual raising and, lowering ofthe sliding sash. tape and the awning. 'As a consequence,

In Fig. 6 Ihave also shown a slight modificationin that the bracket plate28isshortenedby cutting away its lower end. sothat the bail 41 and associated roller; 42 may swing rearwardly without, interference from the plate-.28: v

' The specific the mechanism. entirely fooltproof and to prevent faulty winding of the awning 'on its roller evenif the tape is. carelessly handled or jerked; The flanges of-lthe channel pieces24 and 30 retain-thetape 32 against lateral movement int-such. a manner that only a true torque maybe applied tan- The tape cannot slip sideways with a resultant, drawing oil action or partial longitudinal strain being imposed on the roller which might, crease or jam the awning.

The bracket fixtures. of the present invention are devoid of springs,ge ars and delicate mechanis n; which might be injured by careless or strenuous handling of the manipulating tape, the tape retarding ,mechanism which is carried by the inner retarding action on the tape as the tape is drawn over them in either direction.

It will be seen that there is herein described. a device in'which the several features of this invention are embodied and which device in its action attains the various objects of the invention and is .well suited to meet the requirements of practical use.

As many changes could be made in the above construction and many apparently widely different embodiments of the inven tion could be made without departingifrom the scope thereof, it is intended that all matter contained inthe above description or shown.- n he c mp nying" drawingssha l bracket construction herein illustrated is especially designed. to render limiting. sense.
