'As s hownin Fig. ll, the side enclosurewood members;

Fig. 1'2`is a partial sectionalview o'fthe lower left hand side of the window, as viewed from the inside, showlnga 20 are each provided with an L extension as 29, so as toform a vertical surface 30 on which the front face of the adjacent side channel is seated. A vertical moulding strip,y as 32, abutsthe rear face of the side channel to hold it Securely in'pla'ce.' 'The inside of the Window structure is suitably enclosed by any suitable moulding board as 34. W-The frame side channels 10 and 12',arel each provided on the front side thereof with an integral longitudinally extending, forwardly projecting extension 36 in which is formed va groove.38 for the reception of a suitable sealing means 40, which is preferably made from a vinyl plastic or the like., Fixedly mounted on the vertical moulding strip 32 is a longitudinally extending vertical retaining 'member 42 which is made from any suitable metal, wood, plastic forthe'like. The' retaining member 42 is fixed in place by any ysuitable means, as by the screws 44 `and is provided with agroove 46 on the outer edge thereof in which is suitably mounted a suitable'sealing means. 48 similarto the sealing means 40.. The sealing means 40 and 48 operatively engage the side edges of the'upper and lower sash members 50 and 52, as explained more fully hereinafter.

As shown in Fig. 13, there is mounted on the outer face of'the top channel 14 a horizontal member 54, made from wood or any other suitable material, and which is provided with an upper L extension 56 secured'to the channel face by any suitable means as the screws 58. The member 54 encloses the lower edge of the front leg of the channel 14 and extends inwardly as designated by the numeral 60 and abuts the rear leg of the channel 14 to which it is secured by any suitable means as by the screws 62. The lower surface 63 of the member 54 tapers inwardly and upwardly and has formed thereon a pair of spaced-'apart longitudinally extending grooves 64 in each of which is suitably mounted a suitable sealing means as 66 which is similar to the sealing means 40. The sealingmeans 6,6 operatively engages the upper edge ofthe upper sash' member 50 as more fully explained hereinafter.

d Asbest seen in Fig.` 7, the bottom channel 16 has fixedly mounted onthe outer face thereof a horizontal plate member 68 which is made from any suitable metal or moulded plastic. The plate member 68 is preferably secured to the channel 16 by the rivets 70. Integral with the plate member V68 is an outwardly sloping plate 72 having an outwardly sloping upper surface 74 adapted to operatively engage the lowerl edge of thelower sash member 52. The plate 72 is provided with a longitudinal integral upwardly projecting lip 76 on its inner edge against which the lower sash member 52 abuts, and with an outwardly sloping sill 80' on its outer edge.` The members 68, 72, 76 and 80 are preferably formed as a unit from aluminum by a, suitable extrusion method.

As shown in Figs'. 6 and 13, the sash members each include an upper rail generally designated by the numeral 82 which is provided with a downwardly extending lip 84'against which is seated a U-shaped longitudinal gasket 86 made from any suitable plastic material. Seated in the gasket 86 are a pair of thermopane plates of glass 88 and 90 whichare spaced apart by a longitudinal spacer strip 92 made from any suitable material, as metal or plastic. The glass plates 88 and 90 are securely held in place by a longitudinal moulding strip 94 which is xed to the rail 82 by any suitable means, as by the screws 96. The upper surfaces 98 of `the rails 82 slope outwardly. The surface 98`on the upper sash member 50 is.adapted to be operatively engaged by the sealing means 66 in the frame member 54, and the surface 98 on the lower sash member 2 is adapted to be operatively engaged by the sealing means 100 onithe lower edge of the upper sash member 50.**`v v As yshown in Figs. 6 and,7, the lower rails-on each of the sa'sli members 50 and`52` are similarto the upper rails on these members and are also marked with the numeral 82. The only difference is inthe bottom edges of the rails. The lower edge 102 on the lower rail of the upper sash member 50 slopes outwardly and is provided with a pair of spaced apart grooves or slots 104 in which is mounted a suitable sealing means which is similar to the sealing means 40 and which operatively engages the sloping surface 98 on the upper edge of the lower sash member 52. The lower rail 82 on the lower sash member 52 is provided with an outwardly sloping surface 106 in which is formed a pair of spaced apart grooves or slots 108 in which is mounted a suitable sealing means 110 which operatively engages the sloping surface 74 on the member 72.l

As shown in Fig. 11, all of the side or vertical rails 112 of the sash members 50 and 52 are similarly formed from the same material as the horizontal rails 82 and contain the vertical edges of the glass panes 88 and 9@ and the gasket 86. The rails 112 are substantially T shaped with one leg 114 of the T forming an abutment for the gasket 86. The glass panes are secured in place by the vertical retaining strips 116 and the screws 118 in a similar manner as is used on the horizontal rails 82. The other leg 120 of the TV extends sidewardly toward the side channels 10 and 12 and the inner surfaces thereof, as 122, operatively engage the sealing means 40. The inner sides 124 of the side rails 112 operatively engage the sealing means 48 on the members 42.

As is best seen in Figs. 3, 4, 5 and 1.1, each of the side channels 10 and 12 is provided with a pair of integrally formed, spaced apartlongitudinally extending grooves, as 125 and 126, in which are slidably mounted the elongated inner and outer slides 128 and 130, respectively. In the ,window closed position, the innerslide 12S extends from the upper end designated as 132 in Fig. 13 down to the lower end designated as 134 in Fig. 4, and, the outer slide extends from the upper end designated as 136 in Fig. 13 down to the lower end designated as 138 in Fig. 4. It will be seen that each slide is thus shorter than the overall length of the side channels 10 and 12 so as to permit for vertical travel of the slides in the grooves 125 and 126, in each side channel.

The upper ends of the slides 128 and 130 are slidably retained in .their respective grooves in the side channels by means of an upper elongated bearing plate as which is T-shaped in cross section and overlaps the slides, and which is best seen in Figs. 5 and 13. Each of the bearing plates 140 is secured to their respective side channel by any suitable means, asby-'the screws 142 and dowels 143. The lower ends. of the slides 128 and 130 are slidably retained in their respective grooves in the side channels by means'of a lower elongated bearing plate as 144 which is also T-shaped in cross section and which is secured to the respective side channel by any suitable means, as by the bolts 145 and nuts 146, and this structure is best seen 'in Figs. 3' and 4. The bearing plate 144 is adjustable as more fully explained hereinafter. The slides 128'and v130 are furtherretained in each side channel by a central bearing plate 140a which is similar to the upper bearing /plate 140 and which is secured by similar sc'rews'142a`and 14311.

It will be understood, that each of the sash members 50 `and 52 is operatively connected'to the slides :128 and 130 in the same manner so'that when the slides are actuated upwardly and downwardlyboth'sashmembers will be simultaneouslyand similarly moved.' Furthermore, each side of .each sash member lis operatively connected-to the respective adjacent slides 128 and '130 in a similar manner. Accordingly, the connection structure is the same for eachV side of each sash member and only one side of a sash member. is illustrated. As is shown in Figs. 3 and 4, a T-shaped bracket 148 is secured to the upper side corner of each of the sash members 50 and.52 by any suitable means, as bythe screws 150.

The upper leg 152v of the bracket 148pivotally carries a horizontal pin 154 whichex'tends therethrough and which is tixedly retained in the boss 156, by'means of the retaining screw 158. The boss 156 is fixed` on 'the upper outer corner of the triangularly shaped lever 160 which is pivotally carried on the outer end of the bracket 162 by any suitable means, as by means of the pivot pin 164. The bracket 162 is xedly mounted on the inner slide 128 by means of spacer sleeves 165 and the screws 166 and the dowel pins 168.

As shown in Figs. 4 and 5, a pin 170 extends through a suitable aperture in the upper inner corner of the lever 160, and is rotatable, but is adapted to be locked in place. The outer end of the pin 170 is provided with a head 172, and the inner end 174 of the pin 170 is threaded and carries the lock nut 176. It will be seen that the pin 170 may be locked in any desired position' in the lever 160. Eccentrically mounted on the outer face of the pin head 172 is a second pin 178 on which is suitably journaled a cam roller 180 which is adapted to extend into the longitudinal cam slot 182 in the bearing plates 140 for the upper sash members, and in the central bearing plates 14011 for the lower sash members. The upper end of each of the slots 182 is tapered in'- wardly as at 184, whereby the cam roller 1'80will be cammed inwardly at this point to draw the upper end of the sash members securely into engagement with the sealing means in the window frame when the sash members are closed.

As best seen in Figs. 3 and 4, each sash member 50 and 52 is provided on each side thereof, about one-third of the way down from the upper ends thereof, with a bracket 186 which is secured 4to the side of the sash member `by any suitable means as by the screws 188. On each side of each of the sash members 50 and 52 'is provided an operating lever as 190, the upper endof which is pivotally mounted on the brackets 186 by any suitable means, as by the pin 192. Fixedly mounted on the lower end of each of the outer slides 130 is an L- shaped bracket 194 to`which the lower ends of the levers 190 for the lower sash member 52 are pivotally mounted by any suitable means, as by the pins 196. The levers 190 for the upper sash member 50 would be similarly pivota'lly mounted on brackets 194 and would be' properly positioned on the slides 130 for actuating the upper sash member.

Each of the lower corners of the sash members 50 and 52 would be lprovided with cam locking means, as illustrated in Figs. 3, 4 and 20, which includes the bracket 198 xedly mounted on the lower outer side of each sash member by any suitable means, as by the screws 280. Formed in each of the brackets 198 is a camslot 202 which starts from the rear edge of the bracket and projects forwardly and downwardly. A cam pin'204 is iixedly mounted in each of the brackets 194 on the outer slides 130, by means of a screw as 206 which passes through the bracket 194 and is eccentrically mounted in one end ofthe pin 204. The cam pins 204 coact with the cam slots 202 to securely draw the lower ends of the sash members 50 and 52 inwardly during the last part of the closing travel of the sash members, against the double sealing means around the sash members. The eccentric mounting of the 'cam pins 204 per' mits adjustment of the cam pins to insure efficient coac tion between the cam pins 204 and the cam slot 262.

As best seen in Figs. 3 and 8, the means for actuating* shaft 222 extends inwardly through the bottom channel.

'6 16 A'into the buildi-ngfand is operated by means described hereinafter.

Fixedly mountedon the lower end of the shaft 216 is the spur gear 224 which meshably engages the horizontal rack gear 226 on the inner side of the window. As shown in Fig. 8, the left end of the rack gear 226 is pivotally mounted at 228 to one end of the clevis 230. The other end of the clevis 230 is adapted to have threadably mounted therein the end of the slide operating cable 234. As shown in Figs. 3 and 4, an L-shaped bracket 236 is xedly mounted in the lower leftV corner of the frame structure by means of the screws 238 and carries thereonl a pair of fxedly mounted spaced apart arms 240 through which is iixedly mounted the horizontal shaft 242. Rotatably mounted on the inner end of the shaft 242 is a'n inner pulley 244 and rotatably mounted on the outer end of -the 'shaft 242 is an outerpulley 246.

The cable 234is led -from the left-end of the rack gear 226, as viewed in4 Figs. 3 and 8, and passes around the inner pulley 244 and extends up and through `the boss. 248 which is xedly mounted onthelower end of the inner left slide 128. The cable 234 is ixedly secured to the boss 148 by any suitable means, as bythe retainer screw 250. A pulley 252 is rotatably mounted on the pin 254 which is vfxedly mounted on the lower left side bearing plate 144, as best vseen in Figs. 3 and 4. The pulley 252 overlies the slides 128 and 130. The cable 234 .passes around the pulley `252 and extends downwardly andthrugh the boss 256 which is xedly mounted' on the lower end of the right outer slide 130. The cable 234 is iixedly secured to the boss 256 by any suitable means, as by the retainer screw 258. The cable 234 passes through the boss 256 downwardly and around the outer pulley 246 and then it passes horizontally to theright side of the window frame through the bottom channel 16, past the outside of the vertical gear shaft 216 and around the horizontally disposed pulley 260 which-is suitably rotatably mounted on the vertical pin 262.

As shown in Figs. 8 and 12, an L-shaped bracket 264 is xedl'y mounted in the lower right corner of the window frame and is Vsecured to the side and bottom channels 12 and 16, respectively, by any suitable means, as by the bolts 266. Swivelly mounted on ythe bracket 264, as by means of the screws 272, are the inner and outer ULshap'ed pulley brackets 268 and 270, respectively. An inner and an outer cable pulley, as 274 and 276, are rotatablyv mounted in the pulley brackets 268 and 270, as by means of the shafts 278 and 280, respectively, which are suit-v ably journaled in said brackets. The cable 234 is adapted to pass from the pulley 260 toward the right side of the window frame and inwardly and around the inner pulley 274, and then upwardly to the boss 248 o'n the right side inner slide 128, over the right side pulley 252, downwardly to the right side boss 256 on the right side slide 130, and downwardly and around the outer pulley 276. The cable 234 then passes from the outer pulley 276 toward the left side of the window frame and inwardly and over itself to a point where it fis joined to the right endof the rack gear 226, by means of the cable connector 282 which is threadably mounted as lat 284 in the clevis 286. The clevis 286 is pivotally connected at 288 to the right end ofthe gear 226. It will be seen that the cable 234r thus -forms a complete actuating means adapted to interconnect the inner and outer slides 128 and 130, on both 4sides of the window Aframe, with the slide actuating gear rack 226.

Aspreviously mentioned, the lower bearing plates 144 on which the pulleys 252 are carried are adjustable lon# gitudinally of the side channels 10 and 12 to permit the taking up of any slack in the cable 234. As shown inv Figs. 3 and 4, the lower bearing plates 144` are 'provided with/elongated holes 289 through which the bolts 145= are mounted. The upper end of each of the lower bearing plates 144 is provided with a threaded hole as 291 in which is threaded an adjusting screw 293. The screw 293 is adapted to pass through 'a block 295 which is spaced apart from itsplate 144 and which is xedly mounted on the respective side channel between the slides 128 and 130, by any suitable means, as by the screws 297. It will be seen that the lower bearing plates 144 may be adjusted to move the pulleys 252 to take up slack in the cable 234 by loosening the nuts 146, turning the screw 293 in the appropriate direction to move the plate 144 upwardly, and, then tightening the nuts 146 to hold the plate 144 in the'adjusted position.

As shown in Figs. 8, 9 and 10,'the inner end 290 of the worm gear shaft 222 is square andis adapted to it into a mating square aperture in the outer end of the cylindrical body 292, and is fixedly secured thereto by means of'the pin 294. A cylindrical sleeve 296 is rotatably mounted on the body 292 and is retained thereon by means of the retainingring 2948 which permits relative movement therebetween, but which retains the sleeve 296 on the body 292. The inner end of the sleeve 296 is provided with an integral handle 30. Fixedly mounted in the inner end of the sleeve 296 is a conventional lock barrel 302 which is operated by the usual key 304, and which is retained in the sleeve by means of the pin 303.

As shown in Figs. 8, l and 2l, the cylindrical body 292 is provided with a transverse slot 301 in the inner end thereof in which is slidably mounted the cross pin 305. The sleeve 296 is provided with a projection 306 in which is formed a recess 307. As viewed in Figs. 10 and 21, the left end of the slot 301 communicates with the recess 307 whereby one end of the cross pin 305 may be moved into the recess to lock the body 292 to the sleeve 296 to permit operation of the shaft 290 by the operating handle 300. It will be understood that when the cross pin 305 is in the position shown in solidlines -in Figs. l0 and 21, the sleeve 296 will rotate freely on the body 292.

The cross pin 305 is moved from the inactive position to the operating position by means of the following enumerated structure. The lock barrel 302 is provided with the usual eccentrically mounted key rotor 308 which is free to rotate when the key 304 is inserted in the usual manner. Fixedly mounted on the inner end of the key rotor 308 is a cylindrically shaped cam 309 which is adapted to extend through the aperture 310 in the inner end of the body 292. The aperture 310 communicates with the slot 301 in the body 292. The cam 309 is adapted to be received in a slot 311 in the inner face of the cross pin 305. The cam 309 is eccentrically mounted on the inner end of the key rotor 308. With the key rotor in the inactive or unlocked position shown in Figs. 10 and 21, the cam 309 will be centrally disposed relative to the sleeve 296 and the body 292, and, consequently, the sleeve 296 will rotate freely on the body 292 and the window frame operating mechanism will not be operated. Under this condition, the cam 309 merely rotates in the slot 311 in the cross pin 305, without creating any moving force on the cross pin. However, when the key 304 is inserted in the key rotor 308 and rotated to the right, or clockwise as viewed in Fig. 21, the cam 309 will be turned to the dotted position shown in Fig. 10, and the cross pin 305 will be cammed outwardly to the dotted position shown in Figs. 10 and 21, into the recess 307 in the sleeve projection 306. The sleeve 296 and the body 292 will then be locked together for operating the window frame operating mechanism. The cross pin 305 may be moved back to the inactive position by turning the key back to the initial position shown in Fig. 2l.

The aforegoing structure provides a means for locking the sash members in any desired position, since any pull on the sash members will not move the actuating gears, since the worm gear provides a natural locking action with the worm wheel, and the actuating handle 300 may be disengaged from the worm gear shaft I222, as desired. v

The operating of the novel awning louver window of the present invention will be understood by assuming that the window sash members 50 and 52 are in their fully closed portion as shown in Fig. l. The sash members may then be opened by turning the key 304 so as to cam the cross pin 305 through the slot 301 in the body 292, thereby locking the handle 300 to the worm gear shaft 222. The handle 300 is then turned clockwise, as viewed from the inside of the window, and the worm gear 220 will rotate the worm wheel 218 and the spur gear 224 counter-clockwise, as viewed from the top of the shaft 216. The rack gear 226 will be moved by the spur gear 224 to the right, thereby actuating the cable 234 so as to pull the inner slides 128 downwardly, and to move the outer slides 130 upwardly. When this action occurs, the lower ends of the sash members 50 and S2 Will be swung outwardly, as shown in Fig. 2, with the upper ends of the sash members moving downwardly, and slightly outwardly as the cam rollers move from the tapered upper ends 184 of the cam slots 182 and down into the cam slots 182. The sash members 50 and 52 may be closed by reversing the movement of the handle 300, or by rotating it counter-clockwise. It will be understood, that the handle 300 may be disengaged from the worm gear shaft 222 when the window sashes are in an open position, and that the sashes will then be locked in such open position, since the worm gear 220 locks the worm wheel 218 in place by the natural locking coaction therebetween, and, accordingly, no amount of pulling on the open sashes will move them, and no one can reach into the room and turn the handle since the key 304 will be removed and will not be present to permit engaging the handle 300 with the shaft 222.

Figs. l5, 16 and 17 illustrate a second embodiment of the slide actuation means. The numeral 312 designates a base plate which is xedly mounted in the bottom channel 16 by any suitable means, as by the screw 313. Fixedly carried on the plate 312, by any suitable means, as by welding, is a housing 314 in which is rotatably mounted the horizontal shaft 316 on which is lixedly mounted the worm gear 318. The shaft 316 is adapted to be actuated by a handle, as by the handle 300 of the first described embodiment, and by similar interconnecting structure. The worm gear 318 meshably engages the Worm wheel 320 which is xedly mounted on the horizontal shaft 322 which is suitably rotatably mounted in the housing 314. The shaft 322 projects outwardly from the housing 314 on the left end as at 324, and at the right end as at 326.

An L-shaped bracket as 328 is xedly mounted in the window frame at each of the lower corners by means of the screws 330. Fixedly mounted on each of the brackets 328 is a pair of spaced apart arm 332 between which is rotatably supported the shaft 334 on which is xedly mounted the pulley 336. The shafts 334 are iixedly connected to the worm wheel shaft ends 324 and 326 by means of the couplings 33S. The cable 340 is adapted to pass around the pulley 336 a few turns and be secured thereto by means of the retaining screw 342 to prevent slippage therebetween. The cable 340 is also adapted to be secured to the bosses 248 and 256 on the slides 128 and 130, respectively, and to pass around the pulleys 252 in the same manner as the cable 234 for the first illustrated embodiment of the invention. Since the slides 128 and 130 and lower bearing plates 144 are the same as in the first embodiment, similar reference numerals have been used to indicate similar structure. It will be obvious that the operation of the second embodiment of Figs. 15, 16 and 17 is the same as for the first embodiment except for the operation of the structure connecting the slides to the actuating worm gear drive shaft. When the worm gear 318 is turned, the worm wheel 320 will turn the shaft 322 which actuates age-raves the Ypulleys 336 whichinttirn m'ove the cables 340 so as to'move theslides 128 and 130 upwardly and downwardly in the same 'manner as in th'e vfirst embodiment.

Figs. 18 and 19 illustrate Aa 'third embodiment of the invention wherein the cabl'es340 of the second embodiment are `replaced with chains, as 348. In this embodiment, the Brackets 332a rotatably support a-shaft 334a, in each of the lower corners of the window frame; on each of which is fixedly mounted a sprocket 346 for having operatively 'mounted therearoiind the chain 348. The chains 348 are xedly mounted to thelower ends of the inner slides 128 by means of the retainer blocks 350 which are n'xedly mounted on the s1ides `12S by any-suitable rneari's, as by' Athe 'screws 352. A sprocket 354 is rotatably'nounted 'on a pin 3'55'whic'h isl fixedly mounted on the lower beari'ngplat'e 144"a`nd which sprocket functions for the same purposeas the pulleys 252 in the other described embodiment. The chains 348 pass around the sprockets 354 and are fixedly mounted to the lower ends of the outer slides 130 in the same manner as they are fixed to the inner slides. The operation of the ernbodiment of Figs. 18 and 19 is the same as the operation of the embodiment of Fig. 15.
