Abstract

A U-shaped bracket 10 supports a gear assembly 11. The U-shaped bracket 10 has a front wall 12 with a slot 13 in its upper surface to enable a portion of a shaft 14 between a front bearing 15 and a hub 16 of a gear 17 to slide therein during assembly. The gear assembly 11 has a rear bearing 18 located within an oblong-shaped opening 19 in a rear wall 20 of the U-shaped bracket 10. A portion of the rear bearing 18 rests on a spring 21, which has one end supported on a finger 22 of a post 23 of the rear wall 20 and its other end supported on a finger 24 of a post 25 of the rear wall 20. The slot 13 enables the gear assembly 11 to be pivoted at the front bearing 15 to allow the rear bearing 18 to have a portion positioned on the spring 21 and a portion disposed within the opening 19.

A U-shaped bracket 10 supports a gear assembly 11. The U-shaped bracket 10 has a front wall 12 with a slot 13 in its upper surface to enable a portion of a shaft 14 between a front bearing 15 and a hub 16 of a gear 17 to slide therein during assembly. The gear assembly 11 has a rear bearing 18 located within an oblong- shaped opening 19 in a rear wall 20 of the U-shaped bracket 10. A portion of the rear bearing 18 rests on a spring 21, which has one end supported on a finger 22 of a post 23 of the rear wall 20 and its other end supported on a finger 24 of a post 25 of the rear wall 20. The slot 13 enables the gear assembly 11 to be pivoted at the front bearing 15 to allow the rear bearing 18 to have a portion positioned on the spring 21 and a portion disposed within the opening 19. The oblong shape of the opening 19 enables the rear bearing 18 to have slight movement therein. The U-shaped bracket 10 has a motor assembly 26 rigidly attached to the rear wall 20 so that a gear 27 of the motor assembly 26 extends through an opening or hole 28 in the rear wall 20. The spring 21 acts on the rear bearing 18 of the gear assembly 11 to maintain the teeth of the gear 17 in mesh with the teeth of the gear 27 of the motor 26. The front wall 12 of the U-shaped bracket 10 has a transport plate 29 mounted thereon and disposed between the front bearing 15 and a pulley 30 of the gear assembly 11. This provides further support to the gear assembly 11 and pr...
