ALBERT c. ANERKA, or cnIoAco, ILLINOIS.

, WINDOW-SHADE CARRIER.

. Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Window-Shade (Jar riers, of which'the following is a specification. V

This invention relates to window-shade carriers and hasamong its objects the production of such device which will afford the raising and lowering of the mounted shade to accommodate the passage oflight and air above or over the shade rollerQ f r Another object resides in the provision of a movable shade carrier readily adapted for mounting upon the exterior of the windowcasing or between the'window-stops.

A still further object finds embodiment inan adjustable connection bar or shaft and a coupling adapting the use of such carrier to shades of variouslengths.

With these and other objects in view my invention consists in the novel construction, combination, and relative position of the parts "and members shown in theaccompanying drawings, hereinafter described, and particularly pointed out in the appended claims, I

Referring to the drawing in which like reference characters indicate like or corresponding parts:

Figure 1 is an exterior (partly broken) elevation showing my invention as applied to the exterior of a window-casing; and Fig. 2, illustrates a section taken on line 2-2 of Fig. 1. Fig. 3 is a section similar to 22 of Fig. 1, but in this case, illustrating an application of my improved carriers between the window stops. Fig.,4 is anenlarged detail showing the connection of the roller member; and Fig. 5, shows a section taken on line 55 of Fig. 4, showing the flattened section of the roller shaft. Figs. 6 and 7 illustrate sectional views taken respectively on lines 66 and 7-,7 of Fig. 1.

Referring to the drawings which disclose one embodiment of my invention and particularly to the structure shown in Figs. 1 and 2, I provide a pair of channeled guides or tracks 10 and 10 formed respectively left 7 and right hand and of substantially channel cross section (see Fig. with the flange 10 extending slightly beyond the other flange 10 and having an edge 1O bent parallel to 3 Specification of Iietters ratent.

the at 10 The edge10 isprovided-with rack teeth 10? adapted to mesh with teeth 11 of the disk rollers 11, which rollers 11 each include a'pairof guide plates 11 rigidly riveted to the toothed disks 11 and function to confine or guide same upon their respective tracks 10. Each roller 11 is provided with asegmentaI solid portion within the bore thereof for the purpose of rigidly mounting same upon the connecting shaft and" 12 which is correspondingly. formed withthe flattened portion 12 to receive the solid segmental portion of the provide rigid connection therebetween.

The Shaft'ends are also countersunk Withinthe exterior guide-plates 11 as at'12 and have slight extensions 1 2 for rotative mounting within the carriage member 13 ;which comprises aflatplate 13 'with a perpendicularly bent-edge 13 to confine the flan es. 1 Y

Riveted to the carriages 13 are the shade movement thereof between. channel guide commonly used to support window shades in stationary position.

I The carriages 13 and the rollers 11 are interconnec'ted bythe shaft 12 which includes the short member 12 -having a hollow end portion 12" with a-pair of inwardly formed depressions 12 adapted to engage Within the keyway 12 extending almost through the entire length of the long shaft member 12 The ends of shaft 12 having connection with the rollers are identical in construction. 7 The two channel tracks 10 and 10 may be secured to the exterior face of the window shown in Figs. '1 and 2 or same may be secured on the inside face of thestops 17 by.

the omission ofsuch angles 16 and the use of countersunk head screws within the web 10".

Positive means for moving the carriages 1 3 100 edge 18 bent outwardly and parallel to the 105 web 18*. Slidably mounted on the guide" 18 is the shifting device 19 which comprises the base plate 19 having bent edges 19 .and 1 9 which, respectively, embrace the guide flanges 18 and 18 7 A thumb latch 110 lever pivotally mounted at- 2O having an inwardly bent tooth 2O which projects through the notch 19 of the plate 19 is arranged to engage within any one of the series of notches 18 of the guide 18 and therebypositively lock the shifting device against sliding movement thus maintaining the carriages and shade in a desired'stationary position through the medium of the connecting rod 21, one end 21 of which rod is riveted to the carriage plate 13 'rand the other end of'which is formed with a neck 21? of decreased diameter (affording a head 21 11111011 is loosely held within the slot, 22

Y may be readilymade to fitanyshorter shade the shifting device plate 19 of the 1ever20 and the member QO -rigid-ly mounted to theshifting plate 19%.

It; is obvious that the carriages always support the shade roller in horizontalposition, and that a twisting motion is notvpossible due to the coaction of the interconnected rollers, H v V The shade carrier fixture {will-be manufactured to accommodate theaverage long shade in general use and from this length roller by simply cutting the free end of the long shaftmemberlQ to suit. a

A stop button 24: or any other similaj'rjstop may be securedtothe bottom of the-guide 18 to confine the shifting. device. 7 v 7 It will thus be observed that an improved window shade carrier is provided whichis simple in construction, positively controlled 7' scribed my in movement, and one which is low. in cost of production.

I claim 1. The combination in a window-shade carrier, of a pair of channeled guides or tracks, each having a rack in one flange thereof; a carriage mounted on each rack and comprisinga plate slidable in said-guide or track, aidisk-roller having circumferen- 'tial teeth engaging said rack, a pair of circular guide plates riveted to each disk roller 7 r to embra'cethe rack teeth, and asegmental solid portion withinthejbore of said roller;

a shaft extending between saidcarriages,

said shaft comprising a pair 0 telescoping members,--one of said members having depressions engagingv withinjthe keyway of the other and each of said members having a flattened end portionmounted within said bore of each roller means on saidcarriages, for supporting a shade-roller and v a shifting device for one of said carriages; 2. A window-shade carrier comprising a pair of guides eachof hollow construction with the edge of one wall formed to pro- ,vide'a toothed rack,fa plate slidable in each guide and having a'late'ralextension' to bear within the guide and againstoone wall thereof, shade-roller supports secured to said 7 plates,:and means-carriedbyeach plate to cooperate with eachtoothedrack, the said means of the respective-plates being connected for independent relatively longitudinal movement but held against independent 1 rotary movement.

In witness whereof, I, have hereunto .sub-
