Patented Dec. 3),` 1930 YNITEDL JOHN n" sfron-Y,y or OAKLAND, CALIFORNIA ROLLER sonnen Application filed January 11, 1926.. Serial No. 80,499.

The present invention relates to improvements in roller screens and its particular object is to provide a screen of the type described that may be easily adapted to any window frame and that in its structural features is so arranged that it may be reversed very readily in case the frame is constructed so as to more easily accommodate the roller screen in a reverse position.

A further obj ect of the invention is to provide certain improvements in the construction of the roller.

A further object is to provide certain improvenients in the construction of the roller housing or canopy.

A further object is to provide guide means for the sides of the screen and means for latching the screen in any position desired.

Further objects and advantages of my invention will appear as the specification proceeds.

The preferred form of my invention is illustrated in the accompanying drawing in which Figure 1 shows a front view of a window frame'having my screen attached thereto, the screen, housing and the roller for the screen being shown in section;

Fig. 2 is a transverse section taken on line 2 2 of Fig. 1;

Fig. 8 is a fragmentary sectional longitudinal view taken on line 3*-3 of Fig.

While I have shown only the preferred form of the invention I wish to have it understood that various changes or modifications may be made within the scope of the claims hereto attached without departing from the spirit of the invention.

My screen housing one (1) is preferably made to extend clear across the window sash and is formed with a slot 6 in the bottom thereof. A plurality of lips 11 extend outwardly from the extreme end edges of the housing and are adapted to be received in i" corresponding slots 12 in caps 18 each of which caps consists of a plate 14 formed to correspond to the cross-section of the housing and a flange 16 adapted to be telescoped on the end of the housing. After the cap has been placed on the end of the housing fie the projecting lips`11 are turned over for holding the cap in place. A tongue 17 eX- tends downwardly from each cap and allows the latter to be secured to the window farine.

In this housing there is centrally supported a shaft 19 which is held against rotation by making one eXtreme end 21 thereof angular. A sleeve 22 preferably made ofl wood, is revolvable on one end of the shaft 19 and is held against endwise motion by a washer 28 and a split ring 24 accommodated in a small groove 10 in the surface of the shaft 19. A second Washer 26 on the anguf lar portion 21 holds thesleeve 22 against outward motion and allows the sleeve to be locked against rotating motion by passing a pin 27 through registering perforations in washer 26 and the sleeve.

A coiled spring 28 surrounds the shaft and a reduced portion of the sleeve 22 and is fastened at one end to the shaft as at 29 and at the other end to the sleeve as at 31. A tube 32 is fixed to thesleeve 22 in any conventional manner and extends throughout the length of the housing, the free end thereof being held in concentric relation to the shaft 19 by means of a bushing 33 and a washer 34 against which thebushing lies. The function of said pin 27 'is'to maintain the spring in an adjusted tension while the roller is assembled in the housing.

A screen 36 is secured to the tube 32 with one end thereof and may be wound on the tube in vsuch a manner that the other end of the screen extends through the slot 6 in the housing and may be pulled downwardly by unwinding the screen from the tube whereby the spring, 28 is placed under tension and is automatically causedto re-wind the screen when the same is released.

The side edges ofthe screen run in guides 37 which are preferably channel shaped and secured to the window frame by means of scfrews 38 passing through the bottom thereo At the bottom edge of the screen there is provided a rigid element 41, which has a handle 42 in the center and alatch 43 at each side, the latches comprising a guide 44 and a bolt 46 fixed to a member 41 by means of a screw Ll5 extending through a flange 45H A stop 47 is adapted to be clamped upon one flange of the channel as illustrated in Figure l by means of a screw LL8 and may be secured 1n any suitable place for engagement with the latch bolt llo.

The advantages of my invention will be readily understood from the foregoing description. The housing may be fastened in the frame either in the manner described or in a reverse position since the tongues I7 extend downwardly and both front and rear walls are fiat` The handle 4:2 and latches i3 may also be easily changed from the one side of the member 4l to the other side, the changing merely necessitating the unscrewing of a few screws. The channel guides, of course, may be secured in any place so as align with the slot 6 and are arranged so that the securing means does not take un any additional space. The housing` may be easily assembled and the construction of the roller is such that it may be readily taken apart and put together again.

I claim:

l. A screen roller of the character described comprising a non-rotatable shaft having au annular groove at one end thereof7 a, bushing rotatably mounted on said shaft intermediate said annular groove and the end of the shaft, a split ring seated in said `groove. a spring influenced rotatable member surrounding said shaft and supported in spaced relation thereto.

2. A screen roller of the character described comprising a` non-rotatable shaft having an annular groove at one end thereof, a bushing rotatably7 mounted on said shaft intermediate said annular groove and the end of the shaft, a split ring seated in said groove, a washer disposed between the split ring and said bushing, a rotatable member surrounding said shaft and supported in spaced relation thereto. a spring surrounding said shaft and enclosed within said rotatable member, one end of said spring being' attached to said shaft and the other end thereof being attached to said rotatable member.

3. A screen roller of the character described comprising `a non-rotatable shaft having an annular groove at one end thereof, spaced apart bushings rotatably mounted on said shaft, one of said bushings being mounted intermediate said annular groove and the end of said shaft, a split ring seated in said groove7 a washer disposed between the split ring and said bushing, afrotatable tubular member surrounding said shaft and attached to said spaced apart bushings, a spring surrounding said shaft and enclosed within said tubular member, one end of said spring beingattached to said shaft and the masso other end thereof being attached to said rotatable tubular member.

4. A screen roller of the character described comprising a non-rotatable shaft having an annular groove at one end thereof7 a bushing rotatably mounted on said shaft intermediate said annular groove and the end of the shaft, a split ring seated in said groove, a spring influenced rotatable member surrounding said shaft and supported in spaced relation thereto, and means operable for securing said rotatable member against rotation on said shaft.

In testimony whereof I aiiiX my signature.

JOHN H. STORY.
