Roller Band Reciprocating Drive Mechanism

This mechanism is for converting small-amplitude linear motion into large- amplitude linear rolling motion.

The roller band reciprocating drive mechanism, Fig. 1, includes flexible band 3 looped in a general S shape about rollers 1 and 2. Guideways 4 and 5 enclose band 3 and rollers 1 and 2 within a space which is not wider than the combined cross-sectional dimensions of rollers 1 and 2 with band 3 wrapped about them. Guideway 4 is pivotally mounted in mount 6 by pin 7, to provide for convergent or divergent movement of guideway 4 with relationship to guideway 5. Mount 6 also serves to stop the motion of rollers 1 and 2 and band 3, when they reach the limit of travel in that direction. At the opposite end of guideways 4 and 5, end piece 8 restrains the pivotal motion of guideway 4, and also serves as a stop to halt the motion of rollers 1 and 2 and band 3. End 9 of band 3 is secured to guideway 5 by screw 10. Opposite end 11 of band 3 is provided with helical spring 12.

Transverse motion of rollers 1 and 2 from one end of the guideway configuration to the other is initiated, as shown in Fig. 2, by applying a force tending to move guideway 4 into convergence with guideway 5. Angle A, shown in Fig. 1, depicts the angle which a line joining the centers of rollers 1 and 2 makes with a fixed horizontal line, prior to the depression of guideway 4. As shown in Fig. 2, angle A is reduced to angle B when guideway 4 is parallel to...
