Application filed .Tune 12, 1914. Serial No.

To all 'zc/wm 'it may concern Be it known that l, lViLLmir H. CAMP, a citizen of the `United States. residing` at lVoodville, in the county oix Litchfield and State of Connecticut, lave invented certain new and useful Improvements in Door and lVindow Screens, oi which the 'following is a specication.

This invention relates to window and door screens, especially aiming the eliminate trap-l ping` of flies on the interior of a building, and it is the principal object ot' this invention to construct the door and Window screens in a novel manner lieimitting the escape of the flies or similar animate beings which ind their way into a building, permitting them to escape and preclnding their entrance, at least to a` considerable extent.

Another object of the invention resides in the utilization of a reinforcing strip for the margin of the screen, adjacent the escape opening; the strip operating in a. dual capacity7 since in conjunction with reinforcing the marginal edge of the screen above referred to, it likewise provides an abutment on the interiorot the screen, reducing the possibility of the entrance of flies to a minimum. I

A further object is to provide eXtensible Window screens having suitable means in engagement therewith for retaining the sections in a predetermined position.

Other obiect-s as well as the nature, characteristic itat-nies and scope of my inven- L tion will be more readily understood from the following description taken in connection with the accompanying drawings and pointed out in the claims forming a part of this specification.

Referring tothe drawings: Figure lis a front elevational view of a screen constructed in accordance with my invention, Fig. 2

is a transverse sectional view taken on the line 9,-2 of Fig. l, Fig. 3 is a detailed eni larged fragmentary sectional view taken on the line 3-3 of Fig. l, showing the manner in which the screens lare held in a predetermined adjusted position, Fig. is a modified forni of window screen, illustrating its application., Fig. 5 is a front elevation or" a screen door embodying my invention, Fig. 6 is a longitudinal sectional view of the' same, and Fig. 7 is a detailed. enlargedsectional'view of the upper end of the door and Window, showing the manner in which Specification of Letters Patent.

the reinforcing strip is detachably secured thereto.

ln the drawings wherein is illustrated the preferred embodiment of this invention, screen-sections 5 and 6 are provided which are slidably engaged in guides 7, the latter being made of metal and having the Inarginal edges 8 thereof turned at right angles to the body to provide a channel for preventing displacement of the screen-sections, the section 5 being detachably secured there to by screws 9. i

Each of the sections 5 and o has a Wire screening 10 mounted therein, one end of each or'. the sere` rings being engaged with 4one of the sections, while the opposite end thereof is engaged with a bar ll, in order to insure the rigidity of the screen. A inarginal edge of the screening in each olf the sections 5 and (S is remote from its frame so as to provide'an opening 12 therebetween and the :trame which forms the exit for the ies. Each said remote marginal edges of the screening l() is engaged by a reini'orcing strip 13, the latter in the present instance comprising a sheet-metal plate which has the opposite edges thereoi turned into parallelism with each other and engaged with the screening, as shown to advantage in` Fig. 2, said reinforcing strip lying at right angles to the screening 10, so as to provide abutments for precluding, as much as possible, the entrance of the iiies, since it is seen that tlies crawling on' the screening will be retarded in their course, so as to reduce'the possibility of their entrance to a minimum. The lower portion of the reinforcing strips 13 is spaced from the vertical screening, thus forming a cavity into which the ily enters in its movement np the screening and from which it is necessary to ily, as the edge of the strip forms an adequate barrier to his journey along the horizontal section of the screening. The reinforcing strips 13 are detachably engaged with the respective sides of the trames 5 and 6, by screws le, spacing sleeves l5 being mounted on the shanls oli the screws, so as to limit the movement oi' the strips 13, in order that a predetermined space will be provided between the -strips and the sides ofthe sections with which the screws 14C are engaged.'

As is obvious, the screen-sections 5 and l6 may be adjusted to fit windows of various lill)- ,comprising a rack-bar 17,

sizes, suitable means generally designated 1G, cooperating with the sections to hold thc latter in predetermined adjusted positions, said means in the present instance which is carried by the screen-sections 5, while a springlocking element 1S is mounted on a plate 19 on the section G, for engagement with the rack-bar 17, the locking element 18 providing a beveled side and an abrupt side, conforming to the contour ofi the rack-bar, so as to permit sliding of the sections in one direction, but preventing their operation in the opposite direction, unless it is disengaged from the raclebar. The provision of the means 16 further prevents sliding of the sections and (S from the exterior, since the sections will be in their extendedmost positions tor engagement with the windo.Y casing thereby preventing their movement in that direction, while relative movement will be prevented toward each other in view of the abrupt side ot the locking-member 18 which engage-s with the complemental abrupt portion of the rack-bar 17.

My improved lly'escape has been\ shown as associated with a door, the door-trame in the present instance being indicated at 19 and being of the usual or any desired configuration, having a screening mounted therein which is secured to the frame through the medium of the usual reinforcing strips 21. The upper marginal. edges of the screening L0 is remote from the upper end of the frame 19 and is engaged with a reinforcing strip 22, the latter in the present instance beingsimilar to the reinforcing strip 123 ol" the window sections 5 and 6, the strip Q2- beinglikewise formed from a metal sheet 'and folded upon the remote margin ot the screening 20, said strip lying at right angles to the screening to provide an abutment, the opposite ends 23 of said strip extending into engagement with the opposite sides et' the door-trame 19. A reinforcing strip 22 is detachably engaged with the upper end of the door-frame 19 by screws E24, the screws having engaged on the shanks thereof spacing sleeves 25, in order to retain the reintorcinev stripv Q2 in spaced relation to the inner marginal edge of the upper end o t the door-iframe. Similar to the strip 13, the lower portion of the strip 22 is spaced from the screen forming a pocket between the strip and screen from which the iy has to iy to leave because ol the abutment formed by the edge of this portion ot the strip.

'In Fig. 7 the specific v manner in which the lreinforcing strip is engaged with the screening 10 or 20, and the manner in which the reinforcing strip is secured to either of the window sections or the door, is shown. However, it is immaterial to which it is secured and the formation is identical in t maree either instance, hence an object indicated 26 is indicated in Fig. 7 which may be either the door or window as desired.

The construction shown in F ig. 4l., discloses the usual wire screening Q7 which has the upper marginal edge thereot` in engagement with, a bar '28, the latter being made of wood, metal or any other suitable material and extending outwardly from the window casing so as to provide an abutment, and being secured to the window casing in any suitable manner, said bar being adapted 'tor engagement with the window 29 which is mounted thereabove in the win dow casing, it being seen that a space B0 is provided between the bar 2S and the lower marginal edge oi" the window 2S) through which the exit of the jflies is permitted,` but will preclude their entrance in view oi: the abutment provided by extending the bar 2S outwardly from the window frame. rlhe view shown in l? ig. Je is one taken .trom the interior of the window casing with which the screen is associated, since the manner of connection to the window frame, etc., is i1nmaterial,

in operation or' the device when. used as a window screen, it is seen that the sections 5 and 6 are adjusted to conform to the size ot the window traine in which the screen is mounted and it is seen that the sections will be held in a locked position when adjusted in the window casing in view of the coacting locking means 16, this likewise preventing actuation of the sections 5 and 6 from the exterior ot' the window in which they are mounted, permitting of their expeditious relative movement -trom the interior of the casing by merely discngaging the locking member 18 from the rack-bar 17.

It will be understood that the above de,- scription and accompanying drawings comprehend only the general and preferred embodiment of my invention and that various minor changes in details of construction, proportion and arrangement ot' parts may be made within the scope ot' the appended claims and without sacrificingI any et' the advantages ot my invention.

Having thus fully described my invention, what 1 claim as new and desire to secure by Letters Patent is:

l. A device of the character described including a frame, screening mounted in the frame, one of the marginal edges being remote therefrom, and a reinforcing strip carried by said remote margin, the margin being at right angles to the screen for precluding the entrance of flics.'
