Abstract
Abstract An apparatus for separately discharging articles has a compacting channel; a charging plate disposed at the inlet end of the compacting channel and moving towards and away from the compacting channel for sequentially introducing articles thereinto with a simultaneous, intermittent feed of all articles in the compacting channel; and a retaining member reciprocated at the discharge end of the compacting channel in coordination with the movement of the charging plate. The retaining member is in engagement and travels with the leading article in the compacting channel and releases the leading article at the end of the intermittent feed in the compacting channel.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
141 words
In an apparatus for separately discharging articles, the apparatus including an at least approximately horizontal compacting channel having an inlet end, a discharge end and a base plate constituting the channel bottom; a charging plate disposed at the inlet end of the compacting channel for sequentially introducing articles into the compacting channel; means for moving the charging plate back and forth in the longitudinal direction of the compacting channel, the improvement comprising a retaining means situated at said discharge end for engaging the foremost article of an article series intermittently advanced in said compacting channel; and means for reciprocating said retaining means parallel to the longitudinal direction of said compacting channel in coordination with the motion of said charging plate for moving said retaining means in unison with said charging plate in the direction of article feed in said compacting channel.
Claim 2
Dependent Claim
141 words
In an apparatus for separately discharging articles, the apparatus including an at least approximately horizontal compacting channel having an inlet end, a discharge end and a base plate constituting the channel bottom; a charging plate disposed at the inlet end of the compacting channel for sequentially introducing articles into the compacting channel; means for moving the charging plate back and forth in the longitudinal direction of the compacting channel, the improvement comprising a retaining means situated at said discharge end for engaging the foremost article of an article series intermittently advanced in said compacting channel; and means for reciprocating said retaining means parallel to the longitudinal direction of said compacting channel in coordination with the motion of said charging plate for moving said retaining means in unison with said charging plate in the direction of article feed in said compacting channel.
Claim 3
Dependent Claim
23 words
An apparatus as defined in claim 1, wherein said base plate has a swept-back terminus at said discharge end of said compacting channel.
Claim 4
Dependent Claim
44 words
An apparatus as defined in claim 1, wherein said means for reciprocating said retaining means comprises means for initiating the motion of said retaining means in the direction of article feed upon introduction of an article into the compacting channel by said charging plate.
Claim 5
Dependent Claim
43 words
An apparatus as defined in claim 3, wherein said means for reciprocating said retaining means further comprises means for initiating a return motion of said retaining means immediately upon termination of the movement of said charging plate in the direction of article feed.
Claim 6
Dependent Claim
35 words
An apparatus as defined in claim 1, said retaining means including an upwardly extending wedge-shaped projection protruding beyond the surface of said base plate in the initial position and forward motion of said retaining means.
Claim 7
Dependent Claim
36 words
An apparatus as defined in claim 5, further comprising connecting means coupling said retaining means to said means for reciprocating said retaining means, said connecting means including a spring means for resiliently supporting said retaining means.
Claim 8
Dependent Claim
17 words
An apparatus as defined in claim 6, wherein said spring means is constituted by a leaf spring.
Claim 9
Dependent Claim
26 words
An apparatus as defined in claim 1, further comprising brush means for at least partially bounding said compacting channel at the sides and at the top.
Claim 10
Dependent Claim
41 words
An apparatus as defined in claim 8, wherein said brush means includes an upper brush bounding said compacting channel at its top and extending above and beyond a terminus of said base plate at said discharge end of said compacting channel.
Claim 11
Dependent Claim
100 words
An apparatus as defined in claim 8, further comprising spring means disposed vertically spaced from said base plate and extending beyond the zone of said discharge end for urging the articles against said base plate and for pushing a leading article, advanced beyond the terminus of said base plate at said discharge end, downwardly in a direction substantially normal to the length dimension of said base plate; said brush means including two juxtapositioned upper brushes bounding said compacting channel at its top and both extending above and beyond said terminus, said spring means being positioned between said two upper brushes.
Claim 12
Dependent Claim
68 words
An apparatus as defined in claim 1, further comprising spring means disposed vertically spaced from said base plate in and extending beyond the zone of said discharge end for urging the articles against said base plate and for pushing a leading article, advanced beyond the terminus of said base plate at said discharge end, downwardly in a direction substantially normal to the length dimension of said base plate.
Claim 13
Dependent Claim
48 words
An apparatus as defined in claim 11, further comprising connecting means coupling said retaining means to said means for reciprocating said retaining means, said connecting means including an additional spring means for resiliently supporting said retaining means, said spring means being more rigid than said additional spring means.
