Abstract
Abstract A telescoping drapery traverse rod is provided with a motor drive without sacrificing any of the simple consumer installation and adjustment features of conventional draw-cord operated traverse rods. It employes a positive-drive perforated-plastic tape and sprocket combination with the tape being releasably secured to the master carriers in a manner analogous to that of the conventional draw cord arrangement.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
242 words
A drapery traverse rod and motor drive combination comprising: (a) a pair of telescoping semi-tubular members forming a curtain rod, (b) a pair of wall brackets, (c) means at the outer ends of said rod for mounting said rod on said brackets, (d) a drive motor, (e) means for mounting said drive motor on one of said brackets, (f) a pair of master carriers mounted in said rod for sliding motion, longitudinally of said rod, (g) a flexible drive tape, (h) pulley means within one outer end of said rod for receiving and guiding said tape, (i) a length of said drive tape with both ends releasably secured to one of said master carriers to form an endless loop within said rod passing from end to end of said rod around said pulleys, said drive tape releasably secured to the other of said master carriers at an intermediate point between the ends of said length of tape, (j) positive drive means on said drive tape, (k) a drive sprocket within said loop of tape engaging said positive drive means on said tape in positive driving relation, and means mounted on one outer end of said rod for retaining said drive sprocket relative thereto but free to slide within narrow limits in a plane normal to the rotational axis of said sprocket, and (l) a drive shaft on said motor for engaging, and supporting said drive sprocket in driving relation to said tape.

Claim 3
Dependent Claim
91 words
A motor drive and sprocket combination comprising: (a) a bracket for mounting said motor in fixed relation to a base, (b) a drive shaft extending from said motor, (c) carrying means for said sprocket, (d) means associated with said carrying means for retaining said sprocket in free sliding relation to said carrying means, in a plane normal to the rotational axis of said sprocket, and (e) means for connecting said carrying means to said bracket with said drive shaft engaging and supporting said sprocket in driving relation on a fixed axis.
Claim 4
Dependent Claim
91 words
A motor drive and sprocket combination comprising: (a) a bracket for mounting said motor in fixed relation to a base, (b) a drive shaft extending from said motor, (c) carrying means for said sprocket, (d) means associated with said carrying means for retaining said sprocket in free sliding relation to said carrying means, in a plane normal to the rotational axis of said sprocket, and (e) means for connecting said carrying means to said bracket with said drive shaft engaging and supporting said sprocket in driving relation on a fixed axis.
Claim 5
Dependent Claim
56 words
The motor and drive combination defined in claim 2 further characterized by: (e) a drive tape for engaging said sprocket in a positive drive relationship, (f) a drive tape guide housing fitting loosely around said sprocket, and (g) guide-ways in said housing for leading said tape to and away from said sprocket in a predetermined path.
