Abstract
Abstract Apparatus for compressing and packaging articles, e.g. insulation batts, comprises a bomb bay door arrangement for receiving the articles in succession and depositing the articles in a first position in successive batches each comprising a stack of the articles, a compression chamber, a movable support for displacing the batches in succession from said first position to a second position in the compression chamber, a lifting fork for displacing a first one of the batches from the second position to a third position in the compression chamber to allow the displacement of the next succeeding batch from the first position to the second position, a vertical ram for compressing the first batch and the next succeeding batch together in the compression chamber, and a horizontal ram for discharging the compressed articles through a bagging snout for applying a bag to the compressed articles.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
126 words
Apparatus for compressing and packaging articles, comprising: means for receiving the articles in succession and depositing the articles in a first position in successive batches each comprising a stack of the articles; a compression chamber; means for displacing the batches in succession from said first position to a second position in said compression chamber; means for displacing a first one of the batches from the second position to a third position in said compression chamber to allow the displacement of the next succeeding batch from the first position to the second position; means for compressing the first batch and the next succeeding batch together in said compression chamber; and means for applying to the compressed batches retaining means for retaining the batches in their compressed condition.
Claim 2
Dependent Claim
126 words
Apparatus for compressing and packaging articles, comprising: means for receiving the articles in succession and depositing the articles in a first position in successive batches each comprising a stack of the articles; a compression chamber; means for displacing the batches in succession from said first position to a second position in said compression chamber; means for displacing a first one of the batches from the second position to a third position in said compression chamber to allow the displacement of the next succeeding batch from the first position to the second position; means for compressing the first batch and the next succeeding batch together in said compression chamber; and means for applying to the compressed batches retaining means for retaining the batches in their compressed condition.
Claim 3
Dependent Claim
55 words
Apparatus as claimed in claim 1, wherein said receiving means comprise a pair of retainer members pivotable about parallel horizontal axes between closed positions, in which said retainers support the articles thereon, and open positions, in which said retainers are spaced sufficiently to allow the articles to fall therebetween under gravity to the first position.
Claim 4
Dependent Claim
38 words
Apparatus as claimed in claim 1, wherein said means for displacing the batches from the first position to the second position comprise a batch support and means for reciprocating said batch support between the first and second positions.
Claim 5
Dependent Claim
54 words
Apparatus as claimed in claim 3, further comprising a batch retainer movable to and from a retaining position in which said batch retainer extends at least partly across the path of movement of said batch support for preventing return of the articles with said batch support from the second position to the first position.
Claim 6
Dependent Claim
36 words
Apparatus as claimed in claim 4, wherein said compression chamber includes a compression space beneath the second position, said compressing means being movable downwardly to compress the batches in said compression chamber into said compression space.
Claim 7
Dependent Claim
19 words
Apparatus as claimed in claim 5, further comprising horizontal ram means displacing said compressed batches from said compression space.
Claim 8
Dependent Claim
19 words
Apparatus as claimed in claim 6, wherein said applying means comprise a bagging snout communicating with said compression space.
Claim 9
Dependent Claim
43 words
Apparatus as claimed in claim 1, wherein said applying means comprise a bagging snout, said snout comprising two laterally relatively movable sides, and means for displacing said sides towards and away from each other to adapt said snout to articles of different sizes.
Claim 10
Dependent Claim
57 words
Apparatus as claimed in claim 1, wherein said means for displacing the first batch in the compression chamber comprise a support member, first power means for displacing said support member from said second position to said third position within said compression chamber, and second power means for displacing said support member into and from said compression chamber.
Claim 11
Dependent Claim
78 words
Apparatus as claimed in claim 9, further comprising a support carriage vertically displaceable at the exterior of said compression chamber, said support member being horizontally movably mounted on said support carriage, said first power means comprising means for vertically reciprocating said support carriage adjacent said compression chamber and said second power means comprising means for horizontally reciprocating said support member relative to said support carriage for extending and retracting said support members into and from said compression chamber.
Claim 12
Dependent Claim
31 words
Apparatus as claimed in claim 10, wherein said support member comprises a plurality of spaced parallel horizontal bars movable between spaced parallel vertical bars forming one side of said compression chamber.
Claim 13
Dependent Claim
22 words
Apparatus as claimed in claim 1, further comprising upwardly inclined conveyor means for delivering the articles in succession to said receiving means.
Claim 14
Dependent Claim
27 words
Apparatus as claimed in claim 1, wherein said third position is located above said second position and said displacing means comprise means for lifting the first batch.
Claim 15
Dependent Claim
176 words
Apparatus for compressing and packaging batts of insulation material, comprising: upwardly inclined conveyor means for delivery of the batts in succession from the upper end of said conveyor means; means for receiving and temporarily retaining the batts as the batts drop in succession from the upper end of said conveyor means and for depositing the batts in a first position in successive batches each comprising a stack of the batts; a batt compression chamber; means for displacing the batches in succession from said first positon to a second position located in said compression chamber; means for upwardly displacing a first one of the batches from said second position to a third position located above said second position to allow the displacement of the next succeeding batch from the first position to the second position; means for pressing the first batch downwardly onto the next succeeding batch and thereby compressing both said batches together in said compression chamber; and means for applying a covering to the said compressed batches for retaining the batches in their compressed condition.
Claim 16
Dependent Claim
176 words
Apparatus for compressing and packaging batts of insulation material, comprising: upwardly inclined conveyor means for delivery of the batts in succession from the upper end of said conveyor means; means for receiving and temporarily retaining the batts as the batts drop in succession from the upper end of said conveyor means and for depositing the batts in a first position in successive batches each comprising a stack of the batts; a batt compression chamber; means for displacing the batches in succession from said first positon to a second position located in said compression chamber; means for upwardly displacing a first one of the batches from said second position to a third position located above said second position to allow the displacement of the next succeeding batch from the first position to the second position; means for pressing the first batch downwardly onto the next succeeding batch and thereby compressing both said batches together in said compression chamber; and means for applying a covering to the said compressed batches for retaining the batches in their compressed condition.
Claim 17
Dependent Claim
68 words
