Abstract

A detachable belt cartridge for an envelope feeder includes a housing having spaced apart side walls, first and second end walls, and a top. The top has a plurality of lengthwise slots formed therein. A first and second shaft is rotatively mounted in spaced apart relationship in the housing. A plurality of wheels are drivenly mounted on the first and second shafts by a plurality of endless belts respectively extending around a respective one of the wheels of the first and second shafts such that a portion of said belt extends in a respective slot slightly above said top.

Claims

1. A detachable belt cartridge for detachable mounting in an envelope feeder apparatus, comprising:

a housing having spaced apart side walls, first and second end walls, and a top;

said top having a plurality of lengthwise slots formed therein;

a first and second shaft rotatively mounted in spaced apart relationship in said housing;

a plurality of wheels drivenly mounted on said first and second shafts;

a plurality of endless belts respectively extending around a respective one of said wheels of said first and second shafts such that a portion of said belt extends in a respective slot slightly above said top;

said apparatus having first support means for rotatively supporting portions of said first shaft at one end of said housing such that said first shaft may be slidably removed longitudinally from said first support, a second support means for detachably supporting said other end of said housing.

2. A detachable belt cartridge as claimed in claim 1 wherein said respective side walls of said housing include an inverted V-slot for receiving respective portions of said first shaft and a key slot for receiving respective portions of said second shaft.

3. A detachable belt cartridge as claimed in claims 1 or 2 wherein said apparatus includes

first support members each having a reverse C-grove formed therein, said C-grove slidably receiving a respective portion of said first shaft such that one end of said housing is between said first support members;

a channel support member having a vertically positioned stop member formed therein, said other end of said housing to be slidably received in said channel to rest on said stops;

said channel support member having an opening formed therein, said housing end wall to have a deflectable chip formed therein coactive with said opening for locking said housing in said channel support member, said housing being unlocked by deflecting said clip; and

,

drive means detachably coupled to said first shaft for rotatively driving said first shaft.

4. A detachable belt cartridge as claimed in claims 1 or 2 wherein said apparatus includes

first support members each having a reverse C-grove formed therein, said C-grove slidably receiving a respective portion of said first shaft such that one end of said housing is between said first support members;

a channel support member having a vertically positioned stop member formed therein, said other end of said housing to be slidably received in said channel to rest on said stops;

said channel support member having an opening formed therein, said housing end wall to have a deflectable chip formed therein coactive with said opening for locking said housing in said channel support member, said housing being unlocked by deflecting said clip; and

,

drive means detachably coupled to said second shaft for rotatively driving said first shaft.
