ROBERT sen, or ugean, CALIFORNIA 'ADJUSTABLE SHADE ROLLER MOUNTING Application fiIed March 2, 1932. sen-a 59 ,315. a I

My invention relates'to improvements in ad ustable shade roller mountings, and t conslsts of, the combmat1ons, constructions and arrangements hereinafter described and claimed.

An ObJeCt of my invention is to provide an improvement over the form. .of' the device shown in my coo-pending application, Serial No. 563,197, filed September 16,- 1 931. In said application, I showed identical gripping means for adjustably holding a shade roller in any desired position onthe window and for adjustably holding the bottom of the shade. I further showed common guides for the shade roller and for the shade and disclosed brackets for supporting the shade roller, these brackets being held against swinging motion by having lugsthat are slidably received in the guides.

The principal object of the present invention is to simplify the mechanism shown in my co-pending application and to provide a different type of gripping shoe. ,These improvements will be set forth in the body of the specification.

Other objects andadvantages will appear in the following specification, and the novel features of the deviceiwill be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawing forming a partof this ap plication, in which 1 1 Figure 1 is a front elevation of the device;

Figure 2 is an enlarged detail of a part of thedevice, a portion being shown in section;

Figure 3 is an enlarged detail section taken along the line 33 of Figure 1;

Figure 4 is a perspective View of a guide,- gripping shoe;

Figure 5 is a view similar to Figure 3, but shows a modified guide-gripping member;

and p y p Figure 6 is a view similar to Figure2, but shows the modified member. 1 y

In carrying out my invention, I make use of a window frame, indicated generally at 1, and this frame is provided with the usual sliding sashes 2. Guides 3 are disposedat the sides of the window frame, and it will be noted from Figure 3 that each guide-is provided with a woodrunner l to which metal strip-5 is secured by rivets 6, or other suitable fastening means The strip5 has, openings 4 v 1 therein for recelving na1ls 8, and these na1ls are driven intothe frame-1 and thus-secure the guide 3 in place.

in a S-shape in cross section soras to provide.

two guidech'annels 9 and '10. The guide 7' channel 9 faces toward the wood runner 4,

while the guidechannel 10 faces site direction. I i 1 I now provide two tubular members 11 and 12which are slightly flattened and which are inthe oppoidentioal in. construction, -The member 11 5 supports a shade roller 13, while the member 12 is secured to the bottom of theyshadeil; Sinceboth members 11 and 12 are'identical in construction, the description of one will 7 sufiice. 7 I

InFigures 2 and 3 I show an enlarged de.

tail viewof a portion ofthejmember 12, It

will be noted that this member extends entirelyacross the bottom of the shade 14 and r i that the ends of the member house casings 15,

mount a cam 16, the cam beingpivoted at 17 to the casing 15 and havingv a cam-gripping j edge 18. The pin 17 is received in a slot 17 in the cam 16. A spring 19 v tends to ,swing the cam in acounter-clockwise direction for causing the cam-gripping edge 18 to. bear against the bottom of the channel 10.

A' guide-gripping shoe 19; of the shape shown in Figure-4, is U-shaped incross sectlon so as to slidably engage with the guide 3,

and has inwardly-extending tongues 20, 9 which are slidably received in the channel 10.

The side 21 ofthe shoe-19 is slidablyre ceived in the channel 9. The shoefl19 an ear 22, and the cam 16 is pivoted to theear It will be noted from this'construc-tion that i the member 12 may be manually grasped and moved downwardly, andduring this movement, the cam-gripping edge 18 will slide freely along the bottom ofthe channel 10 and 0 Figure 3 also shows thestrip 5 as being bent V v v the shoe 19 will slide along the guide 3. The spring shade roller 13 tends to wind the shade around the roller, and as soon as the member, 12 is freed, the spring roller will tend to move the member upwardly. This is prevented by the spring 19 swinging the cam 16 in acounter-clockwise direction so that the cam edge 18 and'the shoe 19will grip the guide '3 and hold the member 12 in adjusted position.

The identical gripping means is used in the member 11, except that the gripping means are reversed and the cams 16 are swung into I gripping engagement and tend to prevent the member 11 from moving downwardly; Referring briefly to the member 11, it willbe noted that the cams 16 are connected to adisk 24-by cords 25' that are passed over idlers 26 in the manner shown. The tube 11 has an opening 27 in its .top, and the cords 25 pass shoes 19 will permit this movement.

' inthesame manner as the guide-gripping The member 11 carries shade roller hangers 30,- which in turn carry the shade roller 13. The hangers 30 have wings 31 that are slidably receivedin the channels 10 of the guides 3. v It willtherefore be seen that an upward movement of the member 11 will raise the shade roller 13.

When the operator wishes to lower the member 11, he grasps a disk 24 and moves it toward the tassel 295 'Of course, during this movement, the cords 25 and 28 extend vertically above the member 11'. The movement of thedisk 24 with respect to the guide cord 28 holdsthe strings 25 and frees the cams 16 and this permits the member 11 and the shade 13 to move downwardly. When the desired position is reached, the disk 24 is freed and the 'cams16 and'the-shoes 19 will hold the shade roller in a d'esiredposition.

Since the shade roller 13 is of the spring type, it'willhave'a'tendency to wind the shade 14'th'ereon at allJtim'es. In order to hold the sha'de'in any desired position, I provide the member 12'withthe cams 16 and shoes 19, and

this member will engage with the guides o meansin the member-11. In lowering the shade 14, the t'assel-29'of'the member 12 is grasped,-fand since this tassel is connected directlyto the member 12 bythe cord 28, it will i lower; the member '12. I When the operator w-ishes'to raise the shade 14, he grasps the disk In my C opending application, I showed the rollers 26, disposed adjacent to the cams 16, as being carriedby a separate member which was inserted into the tube. In the present instance, I show the rollers 26'as being carried by the casing 15. Furthermore, in the co-pending.application,I showedthe center rollers 26 as being carried by a separate 1nsortable member, butin the present'case, I show these rollersasbeing carried directly by the tubes 11 and'12.

In this. way, I omit two. roller-carrying members and thus simplify the number of parts.

The gripping shoe 19, shown in this case, isnot disclosed in the 'co-pending;application. It willfurther be not-ed that the shape of the guide 3 differs from that shown in the c'o-pending application. on the hangers 30 slide in the channels 10 instead of-ab'utting against a shoulder, as is disclosed-1n the co-pendmg case.

p The wings are-therefore prevented from swingmg in elther direction.

In Figures 5 and 6 I show a preferred'form V of guide-gripping member, this member taking the place of the cam 16 and the shoe 19. The gripping member 32 is U-shaped in cross section and has a slot 33, (see Figure 6) for receiving the pin 17. The sides of the member 32 are extended, and one side 34 is bent at right angles and is spaced from the end of the side 35. This provides an L-shaped space between thesides 34 and 35 for receiving a portion of the guide 3. g

A spring 36 urges the gripping member 32 into an angular position so to grip the guide 3 and prevent further movement of the-shade 14 in an upward direction. In order to effect movement of the shade up wardly, the cord 25, secured to the member 32, is pulled, and this swings the member- 32 into the horizontalposition shown in Figure 6'. The spring in the shade roller 13 is how strong enough to wind the shade and move the tube 12 and" associate parts upwardly. All of the other parts of the device forming theshade roller mountingare the same and therefore need no further description. The tube 11-is supported in adjusted positionby means of the gripping members 32, whioh take the place of the cams 16 and the shoes 19. I

While I have shown only the preferred form of my invention, it should be understood that various changes or modifications may be made within the scope of the ap--,

pended claims without departing from the v spirit of the invention.
