I Specification of Letters Patent.

, Application at; August 1907. Serial No. 387,523.

To all whom it may concern; Be it known that I, CHARL'ES EJHALL, a citizen of the United States, residing at Rushville, in the county of Rush and State of Indiana, have invented a new and useful Window-Screen, of which the following is aspecification. V

This invention relates to screens for windows, doors, transoms and other closures and has for its objectto provide ascreen capable of 'being readily attached to or' detached from the window frame andwhich serves to effectually preventthe entrance of mosquitoes and other insects to the interior of the rooml A further object of the invention is to provide means for locking the screen in position on the window frame, and means for regulatin the tension of the wire gauze or netting Forming the body of the screen. A still further object 6f the invention is to generally i111 rove this class of devices so as to increase t ieir utility, durability and eflicicncy.

Further objects and advantages will appear in the following description, it being understood that various changes in form,

proportions and minor details of construction may be resorted to within the'scope of theap ended claims.

In t e accompanyingdrawings forming a part of this specification: Figure 1 is a front elevation partly in section of a screenconstructed in accordance with my invention showing the same in position on a window frame. Fig. 2 is'a vertical sectional view of the same. view of one of the locking members. Fig. 4 is a vertical sectional view illustrating a modified form of the invention.

Similar numerals of reference indicate corresponding parts in all'of the figures of the drawings. W

The improved screen forming the subject matter of the present invention is principally designed for attachment to windows and similar closures and by way of illustration is shown in connection with a window of the ordinary construction in which 5 desi nates the window frame, 6 the lower sashand 7 the upper sash.

he screen consists of spaced bars 8 and 9 connected by a strip of wire auze or netting 10 which constitutes the b0 yof the screen and forms a closure for the window so as to effectually preventthe entrance of mosquiroom.

' screen are Fig. 3 is a detail perspective toes or other insects to the interior of the The opposite ends of the'zscreen are nailed or otherwise rigidly secured to the uplperand lower transverse bars 8 and 9 w 1le the o posite lon it-udinal edges of the ent'inwar ly to-form reinforced portions 11. Secured to the inner faces of the bars 8 and 9 are transverseretaining strips 12 and 13 theupper one of which bears against the bottom or meeting rail of the top sash 7,. as shown in Fig.- 2 of the drawings. Secured to the opposite ends of the lower bar 8 are metal wear plates or strips 14 which bear against suita e guide pins or ln s 15 extending laterally from the window rame.

y The guide pins 15 by engagement with the plates 14 serve to retainthe lower bar Set the screenin engagement with the blind stop 16 while 'the upper bar 9 of the screen is locked in position on the blind stop by means of suitable locking members 17.

The locking members 17 are-slidably mounted on the lower longitudinal edge of the upper trans 30 verse bar 9 and are provided with terminal bolts or pins 18. which engage correspondingly sha ed openings 19 formed in the adi'acent e ges of the window frame. The

ower longitudinal edge of each locking mem- 35 her is provided with a vertically dis osed ear 2() which en ages the rearface of t is upper bar 9 while the inner end of the locking memher is bent downwardly to form a terminal finger piece 21 by means of which the bolts may be moved to operative and inoperative position. I

The metal formin the locking members 20 is provided with elongated slots 22 for the reception of screws or similar fastening devices 23 secured to the lower longitudinal .edge of the transverse bar 9 so that the look- .ing members are free to move longitudinally of. the bar when it is desired to remove the screen from the window frame.

or gauze, spaced brackets 24 are secured tothe lower transverse bar 8 with their upper ends seated in recesses 25 formed in the retainin strip 12 and with. their terminal por- 105 of each of which is bent to orm a terminal 11 hook 28 adapted to enga ean eye or loop 29 secured to the wmdowsill while the opposite As a means for regulating the tension of the wire n'ettmge end thereof is threaded for engagement with a wing nut so that by adjusting the wing nuts 30 a longitudinal pull will be exerted on the body of the screen thereby to effect the tension of the same.

Attention is here called to thefact that the lower longitudinal edge of the transverse bar 8 is normally s aced from the window sill so as to permit a imited vertical movement of the lower bar 8 when the nuts 30 are rotated.

in positioning the screen on the window frame the lower transverse bar 8 is inserted between the pins 15 witli the reinforcing edges 11 of the screen in engagement with the blind stop 16, after which the locking members are adjusted longitudinally until the pins .18ent'er the adjacent recesses 19. The nuts 30 arethen rotated on the pins 27 which cause said nuts to exert a downward pressure on the cars 26 and thus effect the stretching of the wire gauze or netting, in the manner before stated.

Inorder to remove the screen it is merely necessary to release the hooks 28 from en- 25 gagement with the eyes 29 and then retract so which the screen 10 extends the entire the lockin members 27 thus permitting the screen to e readily detached.

In Fig. 4 of the drawings there is illustrated a modified form of the invention in height of the winddw frame, the construction and operation of the device being otherwise.

the same as the screen shown in Figs. 1 and 2 of the drawings.

From the fliregoing description it is thought that the construction and operation of the device will be readily understood by 1. The combination with a window frame having horizontally alined openings formed therein, of a screen including spaced trans verse bars, plates slidably mounted on the lower longitudinal edge of the upper bar and and lower sashes, of a window screen inc ud-' ing spaced transverse bars, a strip extending laterally from the upper bar and bearing against the adjacent sliding sash, eyes secured to the bottom of the window frame, brackets secured to the lower transverse bar and having their upper ends bent laterally to form crforated oars, threaded rods ex tending t irough the perforations in the ears and provided with terminal hooks for engagement with the eyes, clamping nuts ongaging the threads on the rods and hearing against the ears for adjusting the tension of the screen, and locking members slidably mounted on the upper transverse bar and engaging the window frame for locking the screen in position on said frame.

"In testimony that I claim the foregoing as my own, I have hereto afliored my signature in the presence of two witnesses.
