Serial 337394.
This invention relates to eirtensibl ewindow screens and has for an object vto'provide a screen; emb'odyinga body part with laterally slidable partsxcontrolledsimultaneouslyand positively by manualmean's.
A. further object- 0f theinvention is to provide an extensible screen comprising a central rigid body part with laterally slidable edge marginal members with means carried by the body part for the application of manual stress translated into driving force for moving the movable members laterally.
A further object of the invention is to provide a window screen composed of a rigidly organized central body portion having side members laterally movable relative thereto for engagement with the window frame and with manual means for moving the laterally movable part in constant parallelism with each other and with the sides of the body portion of the screen.
With these and other objects in view, the invention comprises certain novelparts, elements, units, combinations, constructionsyinteractions, functions and mechanical movements as will behereinafter more fully described and claimed.

The improved screen which forms the subject matter of this application comprises acentral rigid body member A filled as usual with wire or other fabric and with laterally slidable members Band C.

For further stabilizing the parts, dowels 28 and sockets 29 form guides between the sliding members B and C and the body A.
"To maintain the sliding parts B, and C in extended or frame engaging position, a latch employed. This will largely save the cost :The upturned extremity 36 is provided fol-L convenience in releasing the latch from lock ing engagement. 1
In operation, the screen with the sliding parts B and C retracted as shown at Figure 2 and of the proper size will be inserted into the window opening and the lever 23 manu ally moved from full line position to dotted position, which will extend the sliding parts 'the body 2. A window screen comprising a body part, marginal parts mounted to slide laterally relative to the body part, a rod mounted 'to oscillate and extending across the body part in parallelism with the sliding parts, cross-heads mounted upon the rod, one of whichis extended to form a lever, and links pivoted to the crossheads and extending to and connected with the sliding parts.
3. A window screen comprising a body part, laterallysli'dable marginal parts, a rod journaledto oscillate and extending across part in'parallelism with the sliding parts, crosshead s ,mountedrrigidly upon the rod, one of which is extended to form a lever,

B and C to dotted line position so that the sliding parts B and G will engage the window frame, as shown at Figure 5. When in such engaging position, the parts will be locked in such relation by'the engagement of the lock, shown at Figures 6 and 7, with the lever 23, which locking engagement is releasable manually by engagement of the fingeror thumb; with the upturned extremity 36 I of the latch. Releasing the lever and reversing the movement of such lever again retracts the sliding parts B and C so that it may be readily opening.
Itis well known that in modern practice, the sizes of'windows have been standardized'to a great extent and that in the major part ofbuilcling constructions at the present time-stock sizes of'windows are ordinarily employed These stock sizesare'not numerous and tlie window screens of the present construction can readily be madeto conform to such stock sizes and can, therefore, be fabricated at the factory and sold to fit the major portion of the window'openings as at present of' inc lividualscreen construction for separate'windowsg V What Iclaim to be new is: 1. A window screen comprising ally relativejto the body part, a rod removed from the window a a body part, marginal parts mounted to slide laterextending across thefbody part in parallelism with; the sliding parts,- a lever vconnected with the-'- ms l rod, and links actuated by the oscillation of I the rod for sliding he sliding parts in simul; tan'eous parallelism; i l
