App1ication filed May 3,

This invention relates to a combination shade roller and'holding means for windows, andhas for its primary object to provide such a dual construction whereby the shade may besupported at various locations with respect to the window frame for permitting light and air to enter above the, shade when the upper window is lowered or for permitting the entire sash construction to be shaded by drawing downwardly uponthe shade .when the roller is supported at the upper end of the frame p b Other objects. will become apparent as the nature of the invention is better understood, the same comprising the novel form,

combination, and arrangement of parts hereinafter more fullydescribed, shown in the accompanying drawings and claimed.

.1 In the drawings wherein like reference characters indicate corresponding parts throughout the various views Figure 1 is a front elevation of a window equipped with my combination shade roller and holding means. r p 7 Figure 2 is a fragmentary enlarged outer side elevation of the shade andone of the units of the holding means.

Figure 3 is a detail vertical section taken through Figure .1 for disclosing said unit in inner side elevation, 's'aid unit beingv partly broken away, and certain elements of construction thereof being'disclosed in full and dotted line positionQ' i s Figure a] is a. taken through the unit disclosed in Figures 2 and 3, and the adjacent end of the shade roller., Figure 5 is a detail vertical section taken through one end of the shade roller sub stantially upon the line 5 f Figure 2, and looking in the direction toward the right, asper the arrow in said figure.

Figure 6, is a detail fragmentary longitudinal section through'the shade roller con; structed in accordance with the pre sent"invention, and 1 p I I Figure 7 is similar viewthrough the opposite end thereof.

Reference will first be had to theshade roller construction 1I 1OI6' specifically disclosed in Figures 4i, 5, 6 and 7. Said 0on struction [constitutes the provision of a wooden, roller 5 of predetermined length that is formed throughout its length with a b 6 n-Whi h is lees y arra g d a detail. transverse section .1926. Serial No. 106,398."

shaft 7, the opposite ends of whichextend beyond the ends of the rollers and are flattened at said ends as indicated by'the reference character 8 in Figure 4. Upon the ends ofthe roller 5 are metallic cap plates cap plate is formed with a bearing sleeve 9 and 10 respectively while thesleeve 10"" carries a set screw 11 that is formed at its a circumferential channel 12 in the shaft '7 forpreventing longitudinal movement of the same within the bore of the roller.

At one end of the bore 6 within which: i

the shaft 7 is disposed, the same is formed with an enlargement 13, Figure 6, within which 1s arranged a normally unwound coil' spring 14 that surrounds the shaft and that is anchored at one end to thefshaft and at the opposite end to the adjacent cap plate 9 upon the roller 5.

Pivoted to the cap plate 9 is a hook dog 15, the hooked end of which is adapted'for 60 v 9 and 10, Figure 6 and 7 respectively. Each engagement within an opening 16 in the. ad- 1 jacent side of the bearing sleeve 9 in order that said hooked end may engage within a pair of shouldered notches 17 formed upon the shaft 7 within said bearing sleeve, Fig

ures 5 and Secured to the roller 5 is the usual shade 18 which is adapted to be wound thereon,

and at this point it may be well to state the shaft 7 of the roller is 'to be held against rotation by the action of the holding means hereinafter more fully described. WVhen the shade is fully wound upon the roller,

downward pull of the same will release the shade from the roller in order that it may be positioned at the desired point with respect to the sashes as shown in the window c0111 struction of Figure 1. To prevent the reverse rotation of the roller upon the shaft,

the hook of the dog 15 willengage within either one of the shouldered notches 17 of said'shaft. However, if the'shade is quickly released, the dog 15 will ride over these shoulders even 1n the reverse direction, and

which will turn the roller thereon.

Keyed to the bearings 9 and 10 are spur gears 19-19, Figures 4: and 7 that so cooperate with the holding means hereinafter more fully described forpermitting of the raisingand lowering of the entire roller with respect to the WilldOW,

- permit the spring 14 of the rollerfto unwind through the opening of the window con struction when said upper sash is lowered. Each of the units A and B is of identical construction, and consequentlya description of one. will sutlice for both. a

Eachunit of the holding meai sincludes an L-shaped bar 20 that isso arranged with respect to the inner side of the adjacent windowirame bar asto have the wide s de thereof engagethe adjacent side of the.windowt'rame bar, while the narrow side of the L -bar is at the rear side of the window as clearly disclosed in Figure 2,the outer edge of said narrow side ofthe Lbar bein formed upon its inner face with rack teetn 21, thequpper and 7 lower ends of the:

portionsof the L-bar being formed with said rack teeth being in sections 21- 21 that are pivoted ,tothe har asclearly disclosed in Figure 3, said sections being 11015 inally maintained in longitudinal alignment with the stationary portion of thetoothed side not said bar by reason of spring strips 22--22 that are secured to said pivoted sections and to the stationary portion of the bar. h

Upon the lower toothed sections 21 of each unit is a depending strip of metal 28' that extends beneath the L-bar of the unit in order said section maybe swung outwardly to the dotted line position disclosed in-Figure 3,and there be maintained by reason of a holding plate 2 l pivote d-to the lower edge of a sheet metal guard plate '25 secured to the front edge or" the L-loar 20, Figure 4.

i Secured to the strip 23 is one end of a chain 26 that extendsthrough an opening in the lower end of the short side of the L-har 20, and then extends upwardly and back of said narrow side to a point adjacent the upper end thereof at which point it passes through an opening 27 in the narrow side of the L-Hloar at whichpoint the chain passes through an opening 27 in the narrow side of said L-bar and thence upwardly through aneye28 in a bolt 29 that is secured to the upper frame bar ofthe window frame after which said chain. passes inwardly toward the unit and is anchored as at 30 to the end thereof, Figure 3; It will thus be seen that when the lower section Qlis moved outwardly into the dotted line ositionolt Figure 3, a pullwill because upon "the chain for drawing outwardly upon the upper section 21 as also disclosed in the dotted lines of the same figure,or in a manner and for a purpose hereinafter more fully described;

The wide sides ot the L-bars 20 of each unit A and B is formed throughotlt its length i with a channel 31 within which the flattened ends 18 of the roller shaft 7 are mounted for ranged over the outer side of thelLbar 20,

the outer end thereof being secilred t'o the upperjpivotal section 21 of the narrow side of said L-har in order that when said section is swung ,forwardlyfto the; dotted line p'ositionof Figure 3, the in will engage beneaththe respective en oi'fthe shaft? for preventing the droppingof the roller after the'teeth carrying sections 21 of the unit have been moved away from the" gears 1919. At this point it maybe well to state that the teeth of the gears areadapted for mesh with the teethof the angle'har s,

in order that a turning ofithe roll er while in mesh with the teeth of the bars oftl'ie unit will cause the upper and lowermove ineiit of the roller in order that the same may be arranged at any desired posjticnwith respect to the window frame. Obviously, when the roller has been moved toa position at the upper ends o'fthe units orfiat the lower ends thereof and theseeubns ino'ved outwardly to the dottediline positions of Figure 3, the roller may be rotated in ref verse direction tor unwinding or winding the shade 18 without the consequent vertical movement of said roller.

Detachable pins 37 are provided for engagenient within registering openings in the guard platef25 and the narrow side of the L-b'ar 20' at the lower end of each unit for preventing the dropping of the roller from theunit whenthe lowersectionshave been moved outwardly to permit of the rotation of the roller without thelconsequent rising of the same ithin the unit. These pins are however. readily" detachable in orderthatth roller be removed fromtheiinits whenever: desire-d. I

It will thus be "seen that I 'have ptov ltle'd a, combination, shade r01l er,.a-nd iid-laiiig means {6r windows that is a e-11 adapted i01 allthe purposesheretofore designated, even th h h veh in Shbwtl nd. de 't libed the. invention as; omprising. centers :deta-i'l structural elements, it is me helessTto'be understood thatinodifications ay befhad withqutafiecting thespii'itjand scopeof the ap aendedlclaimi avlng thus ass-cassette iaviiaoa, that l te X (if) I claim as new and desire to secure by Letters Patent is window frame and within which the ends of said shaft are mounted for sliding movement, cooperating construction between the units and the roller whereby the shade in its entirety is moved in reverse direction when the roller is turned upon the shaft, means at the opposite ends of the units whereby the roller may be mounted for turning movement without the consequent move ment of the same in reverse directions, said means at the opposite ends of the units being simultaneously operable and, means at the opposite ends of the units for preventing the dropping of the shade when said other means are moved to position to permit the rotation of the roller without its movement in reverse I direction with respect to the window.

In testimony whereof I aflix my signature.
