Abstract

Referring to Figures 1 and 2, a pair of stationary sidewalls of a paper transport assembly is generally designated by reference numerals 10 and 12. A paper guide 16 comprises a back wall 18 which is curved at the upper end thereof and has at the lower end thereof a plurality of laterally spaced apart forwardly curved fingers 20 and 24, respectively. Flanges 30 and 32 extend from each side of the guide 16. A pair of laterally spaced flanges 38 is integral with and extends rear-wards from the rear wall 18. A stationary shaft 40 has an end extending through each flange 38. A pair of retainer rings 42 locates and maintains the shaft in position on the flanges 38.

Referring to Figures 1 and 2, a pair of stationary sidewalls of a paper transport assembly is generally designated by reference numerals 10 and 12. A paper guide 16 comprises a back wall 18 which is curved at the upper end thereof and has at the lower end thereof a plurality of laterally spaced apart forwardly curved fingers 20 and 24, respectively. Flanges 30 and 32 extend from each side of the guide 16. A pair of laterally spaced flanges 38 is integral with and extends rear- wards from the rear wall 18. A stationary shaft 40 has an end extending through each flange 38. A pair of retainer rings 42 locates and maintains the shaft in position on the flanges 38.

A pair of U-shaped brackets 44 and 46 is pivotally mounted on the shaft 40 and each comprises a pair of spaced legs 48, 50 extending from a portion 52 connecting the legs. A spacer 53 is located between the legs 50 of each bracket. The shaft 40 extends through the upper portion of the legs 48 and 50 of each bracket and the spacer 53. A block weight 54 is located between the legs 48 and 50 of each bracket and has an opening through which a solid cylindrical shaft 56 for each weight extends. Retainer rings 55 hold the brackets 52 in place on the shaft 40. One end of each shaft 56 is squared (not shown) , which fits into a matching opening (not shown) of its respec- tive leg 50, and a screw 58 extends through the leg 48 into the other end of a respective shaft 56 to secure the same to the bracket. The block 54 freely pivots or floats about its respective shaft 56 with the center of gravity (CG) being located directly below the shaft 56.

A shaft 64 extends through leg 48 of bracket 46 and through leg 48 of bracket 44 and is rotatably supported by the legs 48. Retaining rings 66 hold the shaft 64 in place on the brackets. A pair of laterally...
