SPRING-ROLLER.

Specification of Letters Patent. Patented Dial. 13, 1917.

Application filed January 27, 1915. Serial No. 4,702.

1 '0 all whom it may concern:

Be it known that I, EDGAR HAYsLnrr, a citizen 01"- the United States, residing at Warsaw, in the county of Kosciusko, State of Indiana, have invented certain new and useful Improvements in Spring-Rollers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in shade rollers and particularly to the spring ratchet rolling mechanisms therefor.

One object of the invention is to provide a device of this character which is simple in construction, and which can be readily applied to a roller without the necessity for drilling a bore in the roller to receive the spring.

Another object is to improve the construction of the ratchet mechanism.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawings.

In the drawings:

Figure l is an elevation of one end of a shade roller having my improved winding mechanism mounted thereon,

Fig. 2 is a longitudinal sectional view on the line 22 of Fig. 1,

Fig. 3 is an end view of the device, the outer plate being removed, and

Fig. 1 is a perspective view of the end plate.

Referring particularly to the accompanying drawings, 10 represents a cylindrical cup, to the outer face of the bottom of which is secured a circular flange 11. In the bottom wall of the cup is formed a central opening 12 through which extends one end of a pintle 13. This end of the pintle is bifurcated and receives therein one end of a coil spring let disposed within and connected to the cup. A disk 15 is secured within the cup adjacent the other end and through the center of this disk extends the before-mentioned pintle. Disposed on the pintle outwardly of the disk 15 is 2. rectangular plate 16 from the central opening of which and comi'uunicating therewith are curved slots 1.7. Formed in the sides of the pintle at diametrically opposite points are recesses 18 which are adapted to register at times with the inner ends of the slots 17.

Disposed within the slots are balls 19 which are adapted to lie within the outer ends of the slots at times and at times partly within the inner ends of the slots and partly within the recess of the pintle. W hen in the latter position the plate and pintle are effec tively locked together so as to prevent any movement under the influence of the spring 1 1. Outwardly of the plate 16 is a disk 20 in the center-of which is formed a recess 21 of a size to snugly receive the beforeanentioned plate 16 therein and hold said plate against rotation. In the bottom wall of the recess is a circular opening through which the flattened end ot the pintle 13 passes. The cup is provided with tongues 23 which are adapted to be bent over the outer face of the plate ordisk 20 to hold the same against displacement. The flange 11 is formed with a plurality of openings 24. The end of the shade roller or stick 25 is inserted within the flange 11, and then a couple of nails or screws passed through the openings 2% and driven into the roller.

It will thus be seen that when the roller is turned in one direction the spring 14 will be wound tightly on the pintle 18, when said pintle is properly held in a slotted shade bracket. The parts of the device being secured to the roller will rotate therewith and as the slots 17 dispose themselves in a vertical line the ball of the upper slot will fall into the upper recess of the pintle thus looking the roller against rotation in the opposite direction, the lower ball dropping into the lower end of thelower slot. Thus the roller can be held against rotation in any position due to the fact that one or the other oi the balls will partially engage in its slot 16 and one of the recesses of the pintle.

Attention is also called to the fact that the outer plate has a recess of the same size as the plate 16 thus holding the plate against rotation on the pintle.

While I have shown and described the locking plate 16 as disposed on the outer portion of the pintle, I wish it understood that the same may as readily be applied to the inner end without altering the intent or operation of the device.

IV hat is claimed is:

A spring winding device for a shade roller comprising a cup member, a circular flange carried by the cup for the reception of one end of a shade roller, a spring within the cup and having its outer end attached to the cup, a closing disk at the open end 01": the cup, a pintle disposed through the cup and attached to the inner end of the spring, said pintle having diametrically opposite recesses, a rectangular plate disposed on the spindle outwardly of the disk and provided with longitudinally extending and oppositely curved openings, balls disposed in the openings and adapted to more at times into 10 the recesses and inner ends of the openings,

and a cover plate fixed to the cap member and having recess of a size and shape to snugly receive the said plate and hold the same against rotation.

In testimony whereof, I afilx my signature in the presence of two witnesses.

, EDGAR HAYSLETT.
