Description

E 15, W35. c. WHEELER SHADE ROLLER OPERATING MECHANISM 2 Sheets-Sheet 1 Filed 001:. 2, 19s4 Inventor a d W E 6 M w f. Q v Q r M Patented Oct. 15, 1935 UNITED srrs P ENT} 2 Claims.

This invention relates to mechanism for operating a shade roller, the general object of the invention being to provide positive means for locking the roller with the shade in adjusted position and to render it unnecessary to jerk the shade in order to raise the same and also to remove danger of the roller jumping from its supporting brackets if the shade should be suddenly fully wound upon the roller.

This invention also consists in certain other features of construction and in the combination and arrangement of several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Fig. l is a fragmentary front view of a window showing a shade roller equipped with the invention.

Fig. 2 is a fragmentary top plan view of Fig. 1.

Fig. 3 is a section on line 3-3 of Fig. 1.

Fig. 4 is a view of the shaft-carrying end of the roller. 7

Fig. 5 is a view of the movable part of the clutch.

Fig. 6 is a similar view but taken at righ angles to Fig. 5.

Fig. '7 is an end view of Fig. 5.

Fig. 8 is an elevation looking toward the outerface of the bracket.

Fig. 9 is a view of the lever.

Fig. 10 is a section on the line !-|0 of Figure 8.

In these drawings, the numeral l indicates the shade roller which has a pintle at one end for engaging a hole in a bracket 2 while the other end has a longitudinally extending bore therein for receiving the spring 3 which has its inner end connected to the roller as shown at 4 with its outer end connected to a shaft 5, as shown at 6, the shaft being rotatably mounted in the roller by passing through a ferrule i attached to said end of the roller. The outerface of the end of the ferrule is formed with cam teeth 8 and forms a part of a clutch. The shaft extends a considerable distance from said outer face of the ferrule and has its outer end flattened and perforated as shown at 9. The shaft extends into a notch Ill formed in the outer end of the bracket I l and a pin l2 passes through the bracket and through the perforation in the flattened part 9 of the shaft so that the shaft is held against rotation and the roller rotates around the shaft.

A disk l3 has the cam teeth M for cooperating with teeth 8, the disk l3 forming the movable part of the clutch and said disk has a yoke l 5 attached thereto which passes through the notch ill of the bracket II. A spring l6 encircles the shaft and has one end bearing against the disk 13 and the other end against the bracket II so that this spring tends to hold the clutch part E3 in engagement with the clutch part 8. The shaft is grooved as at I! and the clutch part l3 has a key l8 therein for engagement with the groove so that said clutch part I3 has sliding movement on the shaft but is held against ro- 5 tary movement.

An L-shaped lever I9 is pivoted between the depending ears on the bracket and has a short arm adapted to engage the bight of the yoke l5 so that when a chain 2|, connected to the outer 20 end of the long arm of the lever is pulled, the short arm will force the yoke and the clutch part l3 outwardly so as to release said clutch part l3 from the clutch part 8 and thus the spring 3 turns the roller l to wind or partly wind the shade 5 thereupon. Of course, when the shade has reached the desired height, the chain 2| is released so that the spring IE will force the clutch part into engagement to stop further turning movement of the roller. When the shade is pulled upon, the clutch part 8 will simply ratchet over the part I3 to permit the unwinding of the shade.

Thus, it will be seen that I have provided simple means for positively holding the shade in adjusted position while permitting the shade to be raised and lowered and eliminating jerking on the shade to release the dog so that the shade can be partly raised. The invention also eliminates danger of the roller freeing itself from the brackets as often happens when the shade is suddenly entirely wound upon the roller.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

I claim:

1. In combination with a shade roller having a longitudinally extending bore in one end portion thereof, a spring in the bore and a ferrule having a portion closing the outer end of the bore. said 55 ferrule having a bearing opening therein, a shaft having a portion passing through said opening into the bore, the spring being connected to said part of the shaft located in the bore, a bracket to which the outer end of the shaft is connected, a clutch part on the outer face of the end portion of the ferrule, a spring actuating clutch part engaging the same, means for slidably but non-rotatably supporting the spring actuating clutch part on the shaft, and manually operative means for moving the spring actuating clutch part away from the other clutch part to permit the spring in the roller to rotate the shaft.

2. In combination with a shade roller having a longitudinally extending bore in one end portion thereof, a ferrule connected to said end and having a part closing the outer end of the bore, said part having an opening therein and a spring in the bore having one end connected with the roller, a. shaft passing through the opening into the and having one end engaged with the bracket and 10 the other the movable clutch part, and a substantially L-shaped lever forming .a long arm and a short arm, pivoted to a part of the bracket below the yoke and having its short arm extending upwardly for engaging the bight of the yoke and a 15 flexible member connected to the long arm: for rocking the yoke causing the short arm to move the yoke and the movable clutch part out of engagement with the other clutch part.
