Another objectsof this inventiontisrto. provide means for conveniently,locking thescreenin extended, position.

Another objectof 5 this; invention. is to provide. convenient mean-s. for: preserving the-P door. 111-- closed position, that is, preserving the openframa disposed across the doonjambt. Another object of; this invention is to. provide convenient means forunlockingsthe screen-from the swinging stile of the doorlso that-the screen vention resides in certain novel features ofhconstruction, combination and arrangement ofiparts and *portioneyas will be hereinafter descr ibednin detail andrparticularly set forth inrthe appended 1 claims.,=ref,er.ence being had withe -accompanying drawings which form a materialwpart ofi-thisaprplication, and in which:

Figure l is a front elevational view of a screen door constructed according to this invention;

Figure 2 is a similar view but showing the screen retracted, to provide for free access through the door;

Figure 3 is a horizontal sectional view, fragmentary in character and enlarged, the view being taken on the line 3-3 in Figure 1;

Figure 4 is a similar view but showing the parts in the position assumed when the door frame is partially opened and the screen is completely extended;

Figure 5 is a broken vertical sectional view showing the roller and contiguous portions, the view being taken on the line 5--5 in Figure 1;

Figure 6 is a broken vertical sectional view, taken on the line 6-,-6 in Figure 2;

Figure 7" is a brokenv perspective view of the chanriel'imember comprising-a top railof the open frame;

Sigma 8' is a broken similar vievw onthe-bottomra Figure an. a broken view ofthe rule jointedextensiblearms indicating an arm in side elevation-p v Fig. 9a is a top-plan view of Fig-uraQ; and-- Figure 1 01 i's aview ofthe spring: means whereby. the; door is urged into closed it position; the view being technically a-horizontal sectional view takenon the line In -ID of Figure-5.

Similar characters of reference: designate similar or identical parts and portions through' out the specification andthroughout the sev eralfviews of the drawings Referring now to: these drawings in: detail," which drawings representone preferred embodi ment' of this inventionyit will be noted thata doonjamh'lHl-havingl asill 12-; is-shown with this improveddoor mounted-therein, The opemframe door. is comprised oi an upright tubular member I 4 whichis slotted as atl 6 and provided-with tangentially disposed neck member I8 extending thetfull vertica-lr height of-this memben It; to-

gather. with an: upper rail -2 il which is-channeled asra-t "22, a swinging stil memberiflr and mower rail- 26 which is channeled asat 28: The above four frame-members will beintegrated ttigether as byiaweldingsto form a--rectangu1ar open name with:thachannelsr22-and-28 and theneck ||8-al l disposed towards the inside of-=theopen-frame? The tubular member M 1 may *be considered the hingedi eof this door and a roller 30 1 is;

mountedaxiallyrthereof'by :the tefiminal pins #32 and 34L If reference isrhad-to= Figure 10 it "Willbe seen how the pin 32 is urged to turn in one direction by a spring 36 terminally secured to this pin 32 and to the cap-like mounting 38, which latter is embedded in and rigidly secured to the sill l2 of the door frame. Since the pin 32 is rigidly secured to the tubular member M, it will be seen that the spring 36 is effective in urgr ing the door into closed position.

At the upper end of the roller 30 there is provided a coil wire spring 40, one end of which is secured to the roller 30 and the other end is secured to the pin 34 and the pin 34 is mounted after the fashion of window blind rollers in a cap mounting member 42. v A generally rectangular sheet of foraminous material has one edge thereof secured to the roller 3|] and is adapted to be wound upon the roller by the action of the spring 40, it being understood that the tubular member I4 is of considerably larger diameter than the roller 30 in order that suficient space 44 is provided for the coiled portion of the foraminous sheet, hereinafter referred to simply as the screen 46. The upper and lower edges of the screen 46 slide within the channels 22 and 28, and the outer edge of the screen is secured to an irregularly shaped inflexible strap member 48, to provide sufficient rigidity to the screen and to facilitate the securement thereof in extended position. The strap member 48 is terminally engaged in the channels 22 and 28, and may be made to more freely slide therein by the provision of small rollers on the upper and lower ends thereof, these rollers being deleted from the drawing in the interest of simplicity. The strap member 48 has a reduced portion 50 and an enlarged portion 52, each coextensive with the length of the strap member, and the enlarged portion 52 is adapted to be grasped by a spring clip 54 formed integral with the swinging stile member 24. It is preferred that this spring clip member 5 3 should also be coextensive with the lengthof the stile member 24, in order that satisfactory locking action be provided over the full length of the outer edge of the screen assembly. It will also be noted that the vertical stile member 24 includes a clip member 56, disposed longitudinally on the outer edge thereof and adapted to engage an elongated U-shaped lock member 53, vertically secured by screws 60 to an inner face of the door jamb Hi.

In order that the screen 46 may be conveniently held in extended position, two pairs of arms 62--68, connected by rule joints w and 1'2, and terminally secured to the neck portion 18 and the stile member 24, are spaced apart as shown in Figure 1 with a connecting link 14 secured therebetween in order that a knob member 16, pivotally mounted on the stile member 24 may be used to actuate all the said arms simultaneously in releasing the arms from their horizontal or locked position, it being only necessary to turn the knob 16 so that the rule joints and 12 are raised.

The operation of this device may be inferred from the foregoing description of the mechanical details thereof but, in recapitulation, it may be well to note that the door can be used in a substantially conventional manner with the

clips

56 and 58 acting as locking members to hold the frame in place, and the door being openable by simply pulling these locking members out of engagement and pivoting the complete assembly on the

pivot pins

32 and 34. The door It also can be used in another manner, the open frame being allowed to remain stationary and the knob l6 turned to release the locking arms 6268, whereupon the spring will cause rotation of the rollers 30 and the retraction of the screen 46 into the tubular member 14, the arms collapsing as indicated in Figure 2.

Many and various minor modifications may be made in this invention without departure from the spirit thereof and though there has been shown a particular embodimentof this invention, this application is not limited to this particular embodiment, but it is desired to include in the scope of this invention the construction, combination and arrangement of parts and portions substantially as set forth in the appended claims.

What is claimed as new and desired to be secured by Letters Patent is:

1. A screen door comprising an open frame having a top rail and a bottom rail, a swinging stile and a hinged stile, said hinged stile having a spring loaded vertical roller, a sheet of foramious flexible material secured at one side to said roller, a non-flexible strap secured to the opposite side of said screen, and channels in said top and bottom rails to receive and to guide the ends of said strap, whereby said screen is retractably extensible across said open frame.

2. A screen door comprising an open frame including, a swinging stile and a hinged stile, said hinged stile having a spring loaded vertical roller, a sheet of foraminous flexible material secured at one side to said roller, a non-flexible strap secured to the opposite side of said screen,

and means to retractably extend said sheet across said open frame, and a latch to detachably lock said strap on said swinging stile.

3. A screen door according to claim 1 and in which said hinged stile is tubular and longitudinally slotted with said roller rotatably mounted therein.

4. A screen door according to claim 1 and including extensible rule jointed arms secured to said hinged stile and to said strap said arms when extended comprising means to lock the screen in extended position.
