Serial No. 414,519.
This invention aims to provide novel means for supporting a shaft for rotation, in a shade structure, and to provide novel means for anchoring to the shaft the tapes that carry the roller. Another object of the invention is to provide a novel means for operating the shade roller for rotation.
It is within the province of the disclosure to improve generally and to enhance the utility of devices of that sort to which the present invention appertains.
With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combi- 5 nation and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes may be, made in the precise embodiment of What is hereinafter disclosed, within the scope of what is claimed, without departing from the spirit of the invention.
In the accompanying drawings:
Figure 1 shows in elevation, a window frame on which the device forming the sub-- ject matter of this application has been mounted;
Figure 2 is a vertical section through the shaft, some parts being omitted;
Figure 3 is a fragmental elevation wherein parts are in section;
Figure 4 is a rear elevation showing how thedleft-hand end of the shade roller is carrie Figure 5 is a section taken approximately on the line 5-5 of Figure 4, parts being left in elevation;
Figure 6 is a section on the line 6-6 of Figure 3.
The numeral 1 marks a window frame, carrying oppositely-disposed bearing brackets 2. The numeral 3 marks a shaft, preferably of wood, and provided with an ornamental covering 4. Drums are located at each endof the shaft 3, but for the sake of simiplicity, description will proceed in the singular number. A cup-shape metal drum 5 is mounted on the end of the shaft 3 and has a flange 6 that forms one wall of the drum.
An end plate 7 abuts against the end of the drum 5 and is of sufficient diameter to form a projecting flange 8 that constitutes the other wall of the drum. The end plate 7 has an outstanding boss 9 provided with an external seat 10. In the end of the shaft 3 is securely mounted a pintle 11 that is journaled in the bracket 2. The pintle 11 passes through the end plate 7 and the drum 5, and has a shoulder 12 which is received in the seat 10 to hold the end plate 7 up in place, as shown in Figure 3, so that the outer portion 8 of the end plate 7 will form the outer wall for the drum 5.
A support 14 is secured to a part 1a of the Window frame 1 and carries a pivot element 15 on which a pawl 16 is mounted to swing in a vertical plane. A torsion spring 17 is engaged with the pivot element 15 and constrains the pawl 16 to cooperate with a ratchet 18 on a metal band 19 mounted on the shaft 3.
The pawl 16 has a laterally extended, loop-shaped arm 20 through which extends slidably a flexible element 21. The flexible element 21 is wound at one end about the shaft 3 and is secured thereto.
In the end of the shaft 3, there is a recess 22 forming a rounded corner 23 in the shaft. An opening 51 is formed in the circumferg0 ential portion of the drum 5, and the material freed in the formation of the opening 51 is turned inwardly to form a tongue 52 extended over the rounded corner 23.
A metal ribbon 24 is wound around the drum 5 between the flanges 6 and 8 of the drum. A portion of the ribbon 24 extends over the rounded corner 23 along the tongue 52 and into the recess 22. The end of the ribbon 24 which is in the recess 22 is fastened by a securing device 26, to form a loop 25 engaged around the pintle 11, the pintle passing across the recess 22, as shown in Figure 3. The loop 25 is slipped on the pintle 11 before the pintle and the drum 5 i are mounted on the shaft 3. The construction is such that the metal ribbon 24 can be used, without breaking the ribbon where it is connected to the shaft 3.
The upper ends of flexible guide wires 28 118 are secured to the brackets 2. The lower ends of the guide wires 28 are connected to screws 29 that can slide for adjustment in eyes 30. Nuts 31 are threaded on the screws 29 and bear against the eyes 30. The nuts 31 and the screws 29 constitute means for tightening the guides 28. A vertical slide bar 33 is provided and has a horizontal stud 32 that slides on the left-hand guide wire 28. The numeral 34 marks a shaft having a reduced end 38 held in the slide bar 33 by a set screw 39. The shaft 34 has a screw driver kerf 37. A fastening device may be used to hold the lower end of one of the ribbons on the shaft 34. The slide bar 33 has a laterally extended stub shaft 35 that is connected in the usual way to the sprin mechanism of a spring-connected roller 46 on which a flexible curtain 47 is mounted.
The stub shaft 35 is mounted in the lefthand end of the curtain roller 46 in Figure 1. In the right-hand end of the curtain roller 46 there is a bushing 48. In the bushing 48 is received the lower arm 42 of a U-shaped hanger 36. The construction is such that the roller 46 can rotate on the lower arm 42 of the hanger 36.
It is possible to loosen the screw 39 of Figure 5, turn the shaft 34 by means of a screw driver in the kerf 37, wind up or slack away the ribbon 24, and thereby place the roller 46 parallel to the shaft 3, the screw 39 finally being set up, to hold the shaft 34 against turning.
The hanger 36 has an upper arm 41 around which the right-hand ribbon 24 is secured at 50. The intermediate or vertical portion of the U-shaped hanger 36 has a longitudinal slot 43. An annular retainer 44 is journaled on the intermediate portion of the hanger 36. The retainer 44 has a longitudinal opening 45. The retainer 44 can be turned until the opening 45 registers with the slot 43. Then the right hand guide wire 28 can be inserted into the slot 43. The retainer 44 is rotated until the opening 45 in the retainer is not in registration with the slot 43, and, thus, the hanger 36 is held on the right-hand guide wire 28 for vertical sliding movement.
The general operation of a device of the class described is well known. The operator manipulates the flexible element 21 to free the pawl 16 from the ratchet 18, and, at the same time, pulls down on the flexible element or slacks it away. The result is that the ribbons 24 are reeled on the drum, or paid off the drum, the curtain roller 46 being raised or lowered.
The operator can place the curtain roller 46 at any desired height, and then work the curtain 47 up or down, in a manner common to all spring-actuated shade rollers.
What is cla med is:
1. In a device of the class described, a shaft having a recess in its periphery, a drum on the shaft and having an opening registering with the recess, an end plate abutting against the drum and forming one flange of the drum, a pintle mounted in the shaft and extended across the recess, the pintle having a shoulder engaging the end plate to hold the end plate and the drum on the shaft, a bearing wherein the pintle is j ournaled, and a shade-supporting ribbon wound about the drum at one side of the flange, the ribbon passing through the opening and into the recess, one end of the ribbon being mounted on the pintle, within the recess.
