Abstract
A device for mounting a paper tractor assembly between the side frames of a computer printer which allows the entire paper tractor assembly to be "popped out" by the application of finger pressure alone, and which eliminates the cost of rounding the ends of the square drive rod of the paper tractor assembly. The mounting device consists of mounting brackets to secure the rods of the paper tractor assembly, bushings to engage the ends of the square drive rod and adapt them to fit into the mounting brackets, and springs or other resilient means to allow the paper tractor assembly to be "popped out."
Claims6
In a computer printer having opposed side frame with mounting holes therein, a paper tractor mounting assembly comprising, in combination, a square drive rod and circular support rod, each rod having a first and second end;
- first and second mounting brackets received in the mounting holes on the inside surfaces of the side frames, each mounting bracket configured on one side for being received in the mounting holes of the respective side frame and configured on the opposite side for receiving the ends of the drive and support rods;
- bushing means on the first and second ends of the drive rod interposed between the drive rod ends and the mounting brackets to allow rotation of the drive rod with respect to the mounting brackets;
- and resilient means interposed between the first ends of each of the drive rod and support rod and the first mounting bracket to hold the drive rod, support rod, and first and second mounting brackets in place with respect to the side frames while allowing for installation and removal of the mounting assembly by first compressing the resilient means with pressure applied to the first mounting bracket and then rotating the mounting assembly.
In a computer printer having opposed side frames and a paper tractor assembly with a square drive rod and circular support rod mounted therebetween, paper tractor assembly mounting means wherein the mounting means for one end of the drive rod and support rod comprises a mounting bracket configured on one side for being received in its respective side frame and configured on the opposite side for receiving the ends of the drive and support rods;
- bushing means on the end of the drive rod interposed between the drive rod and the mounting bracket to allow rotation of the drive rod with respect to the mounting bracket;
- and resilient means interposed between the ends of each of the drive rod and support rod and the mounting bracket to hold the drive rod, support rod and mounting bracket in place with respect to the side frames while allowing for installation and removal of the paper tractor assembly by first compressing the resilient means with pressure applied to the mounting bracket and then rotating the mounting means.
