being hud to the ecoinpunying drawings. This invention relutes to combination window screens und shutters and hns for its object to provide nieuns for fitting the sume into Window trames of various dimensions.

noiher object et the invention resides in the provision of :1"very simple and compnet arrangement of parts mounted upon the frame of the sereenlund udjustul'ile with relation 'to euch other7 undlmeuns tonyieldingly holding said parts in their adjusted positions. i

A further object of our invention is to provide adjustable side plates und u top plate vertically udjustuble upon the side plates!` seid top pluto being formed in 'two -sections for lateral movement with the side plates, und means slidubly mounted upon the side plates and engaging the sections ot the adjustable top plute to hold the sume und said side plates `vieldingly in their adjusted positions. y f

Still another object oit the invention is to provide un adjustable 'freine et simple und extremely durable. construction whereby the proper amount of ventilation muy be obtained.

Vv'ith the ubove und other objects in view, the invention consists of the novel tentures of construe-tion. eombinution und errungement ot puits hereinafter fully desei'il'ied, und eluiined undillustruted in the uncompunving drawings, in which;

Figure 1 is un elevation ot u. eonfihined window screen und shutter constructed in uceordunee with our invention; fig. is u section teken on the line 2-2 et Fie. 1;' Fig. 3 is .u section taken on the line 3&3 ot' Fie'. 1; Fig. 4 is a detail perspective view o? one of the `'fiiides for the adjustable side plates; und Fig. 5 s detail Lerspeetive View ot the holding siring.

Referring in detail to the druwings 5 designates u sill upon which the t'ruine 6 is rigidly mounted. Upon one side oit 'this frame and `to the edges tliereot the screen Wire 7 is secured und between the vertieul sides of the frame 6 u plurality of shutters I8 ure mounted. t

These shutters ,are preftheir longitudinal edges thingedusindicated vide u. practically water-tight connection. An eur 10 is formed upon each end of the shutters through which the pivots 1l ixed in the sides of the frame (3 ure disposed. To the inner sides et the shutters 8 and midway of their length. the eyes 12 are secured. A rod 13 is formed with a plurality posed. The upper` end of this rod is connected to one end of u spring 14, the other end of seid spring being secured to the top of 'the frame 6.. to hold the shutters closed. An operating cord 15 is connected to the lower end of the rod 13 and extends through. un opening 16 in the buse portion of the freine 6. Upon the sill 5 a .corrugated plate l? is fixed and the operating' cord l5 is adapted to be inserted between the eorrugutions of this pitite, the opposite wulls et' the eorrugations clamping upon the operating' eordretuining the shutters in their adjusted positions.

in order to permit of the arrangement of we provide the vertieul side plates 18 which extend substantially the entire height of the freine 6.

zontal iruine members, the'guides 19 are disposed.v These guides :ire constructed from sheet metal bent. into siibstuntizilly tubular torni. The horizontal vframe members are pro vided with the longitudinal grooves 20 to receive the tubular guides. One end of the `guide members is flattened usindieated at 21 und is oountersunk in the edge of the frame oppositely disposed ears 22 which ure'also engaged upon the edge ot' the frame and or other' fasteningr devices. .To the -upper slide members 23 ure secured. These members 'ure ulso formed from sheet metal and ure bent to provide the tubular portions 24 of slightly less diumeter than the tubular guides in which they ure adapted to be received und moved.A The remainder of the plates from which the members 23 are formed provide an uttuohin-g Flange whereby the slide may be rigidly secured to the :id-
