Specification of Letters Patent. Application med october 12, 1907. sei-iai Nn.

To all whom 'it may conc-em;

Be it known that' I, CoNRAD BAUER, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a cer-I tain new and 'useful Improvement in Screens, of which the following is a full,

clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a perspective view of awindow provided with my improved screen; Fig. 2 is a vertical sectional view of the same; Fig. 3 is a front elevation vof the screen showing the window-frame -in vertical section; Fig. 4 is a horizontal sectional view of a portion of the screen and the window-frame showing a portion of the heavy weight or bar in vfull lines; and Fig. 5 is a detached cross section of the weight or bar showing 'the manner of attachment to the blind.

My invention relates to improvements in roller iy-screens which may be applied to windows, doors, or other openings. y

My invention is especially designed to overcome the difficulties heretofore encountered in the use of wire netting for screens which are not permanentlysupported in rigid frames; due to [the tendency of the stii'- material to kink and wrinkle and become misshapen. I have found that spring rollers, such as are used with curtains and cloth fabric, are entirely unsuited to material which has the property of becoming bent and which normally retains a .curvature or set as it is unrolled. I have overcome all of the difficulties mentioned by'- employing a plain roller mounted in suitable bearings upon which the wire netting is wound, and4 attaching a heavy symmetrical metal bar to the bottom edge of the netting, the bar having sufficient weight to positively stretch all wrinkles and curvature from the netting and to pull it down with a force suflicient to make it hang adsolutely taut in any adjusted position. Moreover, by using a plain roller instead of a spring roller and weighting it in the manner described, 'the wire netting will be symmetrically balanced and held evenly across the entire width so that there will be no tendency to roll unevenly.

In the drawings, 2 represents the plain rol ler mounted in suitable bearings, and upon which the wire netting or screen is wound. To the bottom of the wire netting is secured a heavy metallic bar A, which may be formed of sections 4, 5, secured together by Patented sept.'5,i19,11.

screws 6, 6, andV clampin the netting between them. In Fig. 5, t e bar-sections4, 5, are separated by spacing-bars 7, 8, separated vertically from each other toermit the insertion of thin clamping mem ers 9, 10, around which the end wrapped in alternate folds and secured. The ends of the spacing-bars 7, 8, project on each side beyond the main bar-sections 4, .5, and slidmgly fit into vertical grooves 11y 1n the window-frame 12. The be providedy with any suitable winding and retaining' mechanism to coperate with the weight A.

lof the screen is' In the mechanlsm shown, the

roller is provided with a gear-wheel 14,'

adapted to mesh with a gear wheel 15, xed to a sprocket-wheel 16, which is journaled in a vertically sliding bar 17. The bar 17 is operated by means of the lever-arm 18, which is pivoted to a stationary bracket 19, and is connected with the sliding bar 17 by a slot and-pin as indicated at`20.' Extending from the outer end of the lever-arm 18, 1s the rod 21, which is provided with a handle 22, by means of which the rod 21 and lever 18 may be operated to move the bar 17, and to. alternately throw the gearwheel 15 and the locking pin 23 on thebar 17, into engagement with the gear-wheel 15. When the bar 17 is raised, the gear-wheel 15 is placed in mesh with the gear-wheel 14 and the locking pin 23 is simultaneously disengaged. In this position the roller 2 is free to be lowered, or to be rotated in the opposite direction by means of the winding chain 24, to wind the screen upon the roller. When the screen has been lowered into its extended position, the roller 2 is retained and locked by lowering the sliding bar 17 until the pin 23 engages the gear-wheel 14. The heavy bar A stretches the wire netting as it is being'unwound; removing any kinks andthe curvature of the wire so that it will hang perfectly taut' and maintains it taut under constant pull when it is in the lowered or extended position. v

While I have describedin detail the features of construction illustrated in the accompanying drawings, it is to be understood that changes may be made therein without departing from the spirit of my invention or the scope of my claims, which are- 1.
