Abstract
A guide roller assembly rapidly adjustable to accommodate, at different times, lengths of different widths of tape, ribbon or similar material so as to maintain the centers of the widths of such lengths in alignment with a centerline extending about the periphery of the roller of said assembly midway between the ends thereof and during longitudinal movement of each said length over part of the periphery of the roller.
Claims2
A guide roller assembly adjustable to guide, at different times, lengths of tape, ribbon or similar material of different widths so that the centerline of the width of each of said lengths may be made to coincide with a centerline extending about the periphery of the roller of said assembly midway between the ends thereof and during longitudinal movement of each said length over said periphery of the roller, such guide roller assembly comprising;
- A. a longitudinal hollow roller embodying slots extending from near each end of the roller to near the center thereof and having extending through the length of said hollow a shaft for rotationally supporting said roller, the ends of said shaft extending into rotational bearings disposed in a support member therefor and such shaft having threads of opposite hands extending from near first and second ones of said ends of the shaft to near the center thereof;
- B. first and second internally threaded sleeve member screwed corresponding distances onto said threads on said first and second ends, respectively, of said shaft, such sleeve members being longitudinally movable within the hollow of said roller;
- C. first and second flanged wheels correspondingly snugly disposed on the outer periphery of said roller between the center and first and second ones of said ends, respectively, of the roller and slidably movable along the length thereof;
- D. means extending snugly through said slots in said roller and slidably movable along the length of such slots, such means also extending snugly into associated ones of said wheels and said sleeves for rotation thereof correspondingly with said roller;
- E. manually releasable keying means for normally keying said shaft with said roller for rotation thereof in unison;
- and
- F. means for imparting rotation only to such shaft when said keying means are manually released and said wheels and roller are held against rotation thereof.
A guide roller assembly adjustable to accommodate lengths of tape, ribbon or the like of different widths so that the centerline of the width of each said length may be aligned with a centerline extending about the periphery of the roller of said assembly midway between the ends thereof and during longitudinal movement of each said length over part of said periphery of the roller, said guide roller assembly comprising;
- A. a shaft having, extending from near first and second ends to near the center of the length thereof, threads of first and second hands, respectively;
- B. first and second internally threaded sleeves screwed corresponding distances onto said threads on said first and second ends, respectively, of said shaft;
- C. a hollow roller surrounding said shaft and sleeves and spaced therefrom, such roller embodying slots extending from near the ends to near the center of the length thereof and supporting in each such end a tightly fitting bushing, each such bushing embodying a hole for snugly and rotatively receiving one of the ends of said shaft;
- D. a generally U-shaped support member embodying in each of the arms thereof, in alignment with each other, a bearing for receipt of opposite ones of the ends of said shaft for rotation thereof in said bearings;
- E. first and second flanged wheels snugly surrounding corresponding portions of the lengths of first and second halves of the outer periphery of said roller and slidable therealong;
- F. means for keying each said sleeve and a corresponding one of said wheels with said roller for rotation therewith, each such means extending snugly through one of said slots in said roller and slidably movable along such slot;
- G. means on one end of said shaft for rotation thereof;
- and
- H. manually releasable means for keying said shaft with said roller for rotation with each other only when such keying means are in other than their released condition.
