Horizontal accumulating conveyor

A reversible accumulating conveyor comprising a pair of support members, each of said support members including a structure defining a plurality of pressure roller-resting apertures;

• a plurality of carrier rollers connected to the support members and rotatable with respect thereto;
• a plurality of pressure rollers vertically-slidably disposed within said pressure roller-resting apertures, said pressure roller-resting apertures being positioned lower with respect to the situs of said carrier rollers;
• support means attached to said support members for positioning said conveyor at a desired height from the floor;
• a conveyor belt reversible drive means mechanically communicating with the conveyor;
• an endless conveyor belt being driven by said drive means and being trained over and carried by said pressure rollers;
• at least one start belt integrally bound to said conveyor belt and having predetermined characteristics distinct with respect to said conveyor belt;
• and means for vertically urging the ends of said pressure rollers within said pressure roller-resting apertures in order to cause said endless belt to generally maintain a constant pressure against the carrier rollers, excepting when said start belt is carried by said pressure rollers, and to essentially constantly maintain a predetermined back pressure on said conveyor belt in either a forward or a reverse direction with respect thereto;
• said means for urging comprises at least one pressure angle member supporting the ends of said pressure rollers, said angle member having a structure defining a plurality of angle apertures;
• a plurality of bolts vertically disposed within said angle aperture and including a structure having a means for resting the angle member whereupon the angle member rests;
• and spring-biased means surrounding said bolts to vertically urge said means for resting the angle member causing the the ends of the pressure rollers to be vertically biased and float, resulting in pressurizing the endless belt against the carrier rollers;
• said angle members additionally include a structure defining a plurality of second angle apertures, said support members additionally having a structure including a plurality of elongated angle retention apertures capable of registering with said second angle apertures of said angle members, a retention bolt assembly inserting through said second angle apertures and vertically-slidably lodging within said elongated angle retention apertures while slidably retaining said angle members to said support members in order to provide for said floating effect of said pressure rollers when said ends of said pressure rollers are resting on said angle members being spring-biased.
