Abstract

Abstract An envelope transport guide is disclosed that organizes opened and emptied envelopes from an envelope opening machine. The guide has an entry surface coplanar with the pathway of the moving envelopes, and adjacent the opening machine for accepting each envelope. The envelopes turn, under the force of gravity, around some guiding means and slide off the entry surface into an organized stack in an angled collection receptacle.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 131 words
An envelope transport guide for attachment adjacent to the output end of an envelope feeding conveyor which feeds envelopes off the conveyor, which transport guide has an entry surface adjacent to the conveyor and coplanar with the plane of travel of envelopes on the conveyor; guiding means comprising an array of pegs projecting perpendicularly from said entry surface at a plurality of locations on said surface, which array comprises means for allowing the force of gravity to change the direction of travel of envelopes on said surface by substantially a right angle while maintaining the envelopes in said plane of travel of the entry surface; and, a collection means comprising a rectangular receptacle of suitable dimensions which is inclined at an angle of between 21 and 27 degrees from the vertical.
Claim 2
Dependent Claim 131 words
An envelope transport guide for attachment adjacent to the output end of an envelope feeding conveyor which feeds envelopes off the conveyor, which transport guide has an entry surface adjacent to the conveyor and coplanar with the plane of travel of envelopes on the conveyor; guiding means comprising an array of pegs projecting perpendicularly from said entry surface at a plurality of locations on said surface, which array comprises means for allowing the force of gravity to change the direction of travel of envelopes on said surface by substantially a right angle while maintaining the envelopes in said plane of travel of the entry surface; and, a collection means comprising a rectangular receptacle of suitable dimensions which is inclined at an angle of between 21 and 27 degrees from the vertical.
Claim 3
Dependent Claim 115 words
An envelope transport guide as in claim 1 wherein said rectangular receptacle is open-topped and of rectangular parallelepipedal shape such as to receive envelopes falling into it only in lengthwise parallelism and to permit them to stack themselves in ordered parallelism therein, with the horizontal cross-sectional, internal shape of said receptacle being a rectangular oblong such that a standard-sized envelope will always lie in said receptacle with its long edge parallel to the long dimension of said oblong shape, and the transverse dimension of said oblong shape being narrow enough to prevent crosswise deposition of a falling envelope, but wide enough to permit stacked envelopes to be readily removed from said receptacle by the handful.
Claim 4
Dependent Claim 23 words
The envelope transport guide of claim 1, wherein the envelopes are fed off the conveyor at an acute angle relative to the vertical.
Claim 5
Dependent Claim 142 words
An envelope transport guide for attachment adjacent to the output end of an envelope feeding conveyor which feeds envelopes off the conveyor, which transport guide has an entry surface adjacent to the conveyor and coplanar with the plane of travel of envelopes from the conveyor; guiding means for redirecting the path of the envelopes through an angle on said entry surface while maintaining the envelopes in said plane of travel of the entry surface, thereby defining a redirected path; and, a collection means adjacent to the terminus of said redirected path which collection means is capable of accumulating an organized stack of envelopes; wherein said guiding means comprises an array of pegs projecting perpendicularly from said entry surface at a plurality of locations on said surface, which array will allow the force of gravity to change the direction of travel of envelopes.
Claim 6
Dependent Claim 142 words
An envelope transport guide for attachment adjacent to the output end of an envelope feeding conveyor which feeds envelopes off the conveyor, which transport guide has an entry surface adjacent to the conveyor and coplanar with the plane of travel of envelopes from the conveyor; guiding means for redirecting the path of the envelopes through an angle on said entry surface while maintaining the envelopes in said plane of travel of the entry surface, thereby defining a redirected path; and, a collection means adjacent to the terminus of said redirected path which collection means is capable of accumulating an organized stack of envelopes; wherein said guiding means comprises an array of pegs projecting perpendicularly from said entry surface at a plurality of locations on said surface, which array will allow the force of gravity to change the direction of travel of envelopes.
