SHADE-FIXTURE.

Application filed May 21,

To all whom it may concern:

Be it known that 1, WILLIAM MoGonMIoK NnALn, a citizen of the United States, and a resident of Greensboro, in the county of Guilfordand State of North Carolina, have invented certain new and useful Improvements in Shade-Fixtures, of which the following is a specification.

My invention is an improvement in shade fixtures, and has for its object to provide mechanism'in connection with fixtures of the class shown in my co-pending application, Serial #317,528, filed August 14, 1919, for

permitting the shade to be operated in the usual manner without breakage orinjury, and without interfering with the operation of the mechanism forming the subject matter of the said application.

In the drawings:

Figure '1 is an .end View of the improved shade. 1 V

Fig. '2 is a longitudinal section of one end of the shade roller.

Fig. 3 is a view looking from the inner end of the reel, I

Fig. 4 is a view looking at the outer end of the shade,

Fig. 5 is a plan View of the spring,

Fig. 6 is a longitudinal section of the same,

Fig. 7 is an end View of the hub looking at the inner end,

Fig. 8 is a longitudinal section of the same.

I the embodiment of the invention shown, the shade roller 1 which is of wood or other material, has one of its ends tapered as shown, and on this end there is arranged a cap 2 of suitable metal, the cap being shaped to fit the end. The end of the roller has its corner out off, andthat portion of the cap 2 which fits over this cut-off corner has openings 3, the said openings being two in number, arranged on opposite sides of the center of the roller. I

These notches are designed to receive tongues 4 on a reel hub 5, the said. tongues extending circumferentially of the hub, and being offset inwardly from the hub as shown. This reel hub 5 is shaped to fit on the tapering portion of the cap, the large end of the reel hub being inward, and this end has a marginal flange 6. The opposite end of the reel hub, that is, the small end, engages over a hub 7 which hub is of a size to fit the journal pin or trunnion 8 of the shade roller.

Betwee the outer flange 10 of the reel and the hub, there is arranged a spring of the Specification of Letters Patent. Patent ed Aug. .30, 1921.

of the cross bent laterally as shown. in Fig.

6, and the convex side of the spring is arranged adjacent tothe reel smaller end of the hub. The reel hub at theopening for the hub 7 is provided with diametrically opposite notches 17 which are adapted to be engaged by inwardly extending lugs 18 on the spring, to prevent the spring turning with respect to the reel.

The hub 7 before mentioned, has a marginal flange 11 at the outer .end, which fits the outer face of the brake disk or reel end 10, and it will be noticed that that portion of the hub which is within the opening ofthe brake disk is of-greater diameter than the body of the hub.

The inner end of the hub 7 isupset or swaged outwardly as shown, to lock the flange, the hub and the reel together, and the taper of the reel hub flange 5 is such that the inner end of the hub 7 is spaced some distance away from the plane end of the cap. The journal pin 8 is merelyv a spike which is driven into the end of the shade roller, and the shade roller at the cut away corner and at each openingB is recessed, as shown at12, to permit the free entrance of the tongues 4; of the reel hub. r

The cord 13 which operates the shade roller is passed through an opening 14 in the reel hub and is knotted on the inner side of the said hub to prevent disengagement. The engagement between the disk 10 and the reel hub 5 is a. frictional engagement, so that the parts under undue strain may move with respect to. each other. IV hen the brake disk is in engagement with the brake indicated at 15, and forming a part of the shade supporting bracket 16, and someone pulls down upon the shade to lower the same, there can be no breakage or damage to the parts, for the shade roller and the shade may turn with respect to the brake disk 10. The triotional contact however is sufficient to normally cause the parts to turn together, so that the shade will operate in the manner set forth in my previous application.

Users of shades are so thoroughly educated in the use of the usual spring shade, that they will mechanically grasp the shade in the present construction and attempt to operate it in the same manner as the standard spring shade. With the construction shown and described in my prior application before mentioned, this would result in clamage and probably breakage. With the pres out construction however, the shade may yield with respect to the brake, to prevent any damage.

Normally the disk 10 rotates with the reel, but should the shade itself be grasped in an attempt to lower it by force, the disk may remain stationary while the shade is lowered and without injury to the parts. The conical shape of the reel is of advantage, in that it gives the weight of the shade a greater leverage when it is entirely rolled up on the pole and the cord is off the reel. That is the position of the shade when it is most difficult to operate it successfully.

It has been found that shade rollers with rigidly attached reels cannot be used with the shades are installed, the reel is slipped over the end of the shade roller until the tongues l register with the openings 8.

Then the tongues are in the opening, angular movement of the reel will cause the tongues to engage in the manner shown in Fig. 2, thus locking the reel to the shade roller. Since all of the stress on the roller, both when operated by means of the shade and by means of the cord 13, tends to tighten the tongue, there is no danger of accidental displacement. The reels can be easily attached when the shades are installed. The sleeve, hub, or eyelet 7 permits the reel to be easily assembled, the upsetting of the inner end of the eyelet being done by a press as a rule.

I claim:

1. In a shade roller construction, the combination with the roller, of brackets for supporting the roller, said roller being mounted to move vertically and forwardly with respect to one of the brackets, a reel mounted to normally rotate with the roller and having at its outer end a flange frictionally connected with the reel to rotate therewith normally and to slip with respect thereto under undue strain, and brake mechanism in connection with the flange and controlled bythe aforesaid forward and vertical movement of the reel.

2. In shade roller construction, the combination with the roller, of a reel having a tapered socket at one side, said roller'having a housing at one end tapering outwardly and fitting within said taperedsocket, said housing provided with spaced openings intermediate its axis and periphery, said reel having offset tongues intermediate its axis and periphery for engaging within the openings of the housing for connecting the reel to the roller when rotated in one direction, and disengaging therefrom when rotated in the reverse direction.

3. In shade roller construction, the combination with the roller, of a reel, and means for detachably connecting said reel to one end of said roller, said means constraining the roller and reel to turn together when the reel is turned in one direction, and to disconnect the reel and roller when the reel is turned in the reverse direction.

4. In shade roller construction, the combination with the roller, of a reel connected to one end thereof, said connection constraining the roller to turn with the reel when the reel is turned in one direction, and releasing the reel when the reel is turned in the opposite direction, said connection comprising a tapering housing on the end'of the roller, said housing having openings, and the reel having inwardly offset tongues for engaging within the openin s.
