Said means comprises a pair of similar, symmetrically disposed end brackets 89' into which the opposite ends of box 14 are nested and which are fixed in the manner hereinafter described to the mullion 12 and window jamb 13.

Each bracket 89 comprises an endwall 8% from which extends a top flange 89b contactingthe upper surface of top wall 57, and a bottom flange 89c contacting the underside of bottom wall 59. End walls 89a contact the end edges of walls 57, 58, 59 and 511a as well as the end edges of flanges 73, 74, 75, 76, at one end of the box and 73a, 74a, 75a, 76a at the other end of the box.

Extending from walls 89a are flanges 89d attached to the mullion and jamb by screws $92. Also extending from end wall 89a of each bracket 89, at right angles thereto, and between flanges 89d, is a flange 89 contacting the back of wall 50a. A strap 89g is slidably mounted on each bracket 89. Each strap 89g comprises a web 89h contacting wall 58, and flange 89 contacting flange 89b and 890. Said flanges 89b and 89c have slots 89 and 8916 running longitudinally of the box and slidably receive lugs 89! on flange 591'. By sliding off the straps 89g, the box 14 may be slid out of the brackets 89 for replacement, repair, cleaning or any other purpose.

One end of the screen cloth 16 is inserted into grooved portion 96 and clamped or anchored therein by a long rubber pin 162. The cloth screen passes through opening 56 and between guide members 11 for attachment to the operating bar 17 in the manner to be explained hereinafter.

The operating bar 17 comprises a back part and a front cover part 111 attached thereto.

The back part 119 comprises a back wall 112 from the upper end of which extends forwardly a thickened portion 113 formed with a round groove 114 of more than 180, and from which extends forwardly, a central throat 115. The lower wall 116 below the slot 114 has at its forward end, a downwardly projecting lip 118. Extending forwardly from back wall 112, in spaced relation below wall 116, is a wall 119 having an upwardly extending lip 126 opposed to lip 113. Between walls 116 and 119 is-a slot or groove 121. In said groove is a plastic, tubular rod 122 provided with a longitudinal lip 123. The lower end of the screen cloth 16 passes between thickened part 113 and cover 111 of the operating bar, around lip 113 and around rod 22 and its lip 123, and is anchored thereby to the back member 110.

Extending forwardly from back wall 112, in spaced relation below wall 119, is a wall 125 formed at its underside with a longitudinal groove 126. Said wall 125 is also formechat its underside, and forwardly of slot 126, with an inverted V-shaped slot 127 for the purpose hereinafter appearing.

Extending forwardly from the lower end of-wall 112 is a thickened portion 139 formed with a round slot 131,

of more than 180 in angular extent and from which extends a throat 132. The upper side of wall 130 is formed with a slot 133 disposed below and in alignment with and in opposition to slot 126. 7

Cover part 111 comprises a wall 135 in a vertical plane, contacting the front of back part 110 and is attached thereto by screws 136 passing into slot 136a formed between wall 119 and wall 125. Wall 135 has a rearwardly extending rib 137 of inverted V-shaped cross-section engaging in the inverted V-shaped groove 127. Extending rearwardly from the lower end of wall 135 is a flange.

14-1 contacting the underside of thickened portion 130. Flange 14% has at its rear end, an upwardly projecting beveled lip 141 which engages a beveled complementary surface 142 at the lower rear surface of wall 112. At the underside of flange is a T-shaped slot 143 receiving a plastic flexible sealing strip 144 and provided with a. tongue 145 to contact the upper surface of the lower sill of the window frame. In attaching the cover 111 to the back part 110, the lip 137 snaps into the groove 127.

Fixed to the middle of the cover part 111 adjacent its lower edge is a push bar 150. Said push bar has a wall 151 contacting wall 135 and fixed thereto by screws 151a. Extending horizontally forwardly from said wall 151 is a flange 152 engageable by the operator, to push the operating bar 17 up or down. i

The ends of the operating bar 17 are connected to the guides 11 by a pair of similar, symmetrical, anti-rocking 43 of vertical guides 11. Fixed to each bar 161 are a pair of horizontal round pins 162, 162a slidably received in the horizontal slots or grooves 114, 131, respectively. The bars 161 slide up and down in the guides and the pins 162, 162a slide in and out to prevent binding and rocking and to make allowances if the guides are not absolutely vertical. I

Means is provided to releasably latch the operating bar against upward movement at predetermined vertical positions (determined by placement of strike pins 46) while allowing the operating bar to be pulled down. To this end, the wall 112 of back member lit? is formed with a bearing openin 179 centrally located between the ends of the operating bar and its axis located between walls 125, 139. An annular anti-friction liner 171 may be fitted around the inner edge portion of said opening.

Wall 135 is formed with an opening 172 similar to opening 170 and co-axial therewith and it also is provided with an anti-friction annular liner 173. Wall 125 and thickened wall 138 are centrally cut away concentrically with opening 171} to provide a recess 174. Rotatably mounted in the liner 171 is an actuator member 175 comprising a hub 1'76 passing into opening 179, an enlarged hub 177 extending therefrom, and a disc 178 received in recess 174 and provided with a front transverse slot 179. Member 175 has an axial through opening 189. Extending through opening 18% is an internally threaded sleeve 181 which projects forwardly through opening 172. to the front of the operating bar. On sleeve 181 is a tube 182 journalled in liner 173. Said tube is provided at its rear end with lugs 183 projecting into cross slot 179, so as to rotate therewith. At its front end, said tube 182 is provided with a crank handle 185. Screws 1%, 137 are screwed into opposite ends of sleeve 181 toassemble the handle 135 with member 175. 7

Disc 178 is formed with a pair of through holes 196 on a diameter at right angles to cross slot 179, for the purpose hereinafter appearing.

Slidably mounted in the operating bar on opposite slides thereof are latches 191. The upper edges of said latches are received in grooves 126. Their lower edges.

are received in grooves 133. Said latches 191 have outer upwardly and outwardly inclined edges 192. Said latch bars 191 pass loosely through vertical slots 194 in bars 161. Fixed to each latch bar 191 is an inwardly extending wire or pin 196 passing through a guide slot 197 in a lug 198 out from wall 112 and bent forwardly toward cover 111. On guide pin or wire 196 is a coil compression spring 2% interposed between the inner end of latch bar 191 and lug 198. Thus the springs 29d tend to push the latches outwardly and into the planes of pins 46. The inclined edges 192 permit that latches to be pushed back as the screen is lowered, to by-pass the striker or keeper pins 4-6.

Each latch bar 191 has at its lower edge, an undercut edge 201 forming a set back shoulder 292. The rear side of each latch bar 191 is formed with a longitudinally horizontal groove 294. The disc 178 is connected to the latches 191 by connecting rods, pins or wires 2%. Each connector 266 has an offset inner finger 297 engaging in an opening 19%), passes through groove 2% and has a finger 298 engaging shoulder 292. it will now be understood that rotation of handle 185 will cause retraction of the latches inwardly of pins 4-5 to permit lifting up of the operating bar. It will be noted that the handle is close to flange 152 so that both may be engaged by one hand and which is well adapted to meet the conditions of practical use. 1

As possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.

I claim:
