Abstract
Abstract A device for controllably feeding connected bag elements to filling apparatus comprising: a horizontally disposed first bar or elongated member, and a second such bar extending diagonally downwardly from the forward end of the first bar such that the bars open angularly toward the apparatus In operation, the bags are initially threaded top wise over the horizontal bar and then directed downwardly underneath and around the diagonal bar, and therefrom directed to the apparatus. The device is taught for usage with apparatus which mounts the bags as they are received, in a curtain-and-rodlike fashion by means of an open end loop located at the top end of each bag.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
85 words
A device for controllably feeding a chain of connected bag elements to filling apparatus comprising a first elongated member, a second elongated member extending angularly with respect to the axis of said first member, said first and second members opening toward said filling apparatus, said apparatus including means for receiving said chain of connected bag elements from said feeding device, said elements comprising bags having supporting means adjacent the top end thereof, and said receiving means receiving said chain by way of said supporting means.
Claim 2
Independent Claim
85 words
A device for controllably feeding a chain of connected bag elements to filling apparatus comprising a first elongated member, a second elongated member extending angularly with respect to the axis of said first member, said first and second members opening toward said filling apparatus, said apparatus including means for receiving said chain of connected bag elements from said feeding device, said elements comprising bags having supporting means adjacent the top end thereof, and said receiving means receiving said chain by way of said supporting means.
Claim 3
Dependent Claim
13 words
The device of claim 1 wherein saiD first member is generally horizontally disposed.
Claim 4
Dependent Claim
17 words
The device of claim 2 wherein the angle between said first and second members is approximately 45*.
Claim 5
Dependent Claim
12 words
The device of claim 1 wherein said receiving means comprises a mandrel.
Claim 6
Dependent Claim
30 words
The device of claim 4 wherein said mandrel and first member are both generally horizontally disposed, said first member being disposed in the plane of or upwardly of said mandrel.
Claim 7
Independent Claim
143 words
A method of feeding a chain of connected bag elements to filling apparatus comprising: a. directing said chain generally upwardly to a first member, and thereafter b. directing said chain around said first member and then downwardly therefrom to a second member which is angularly disposed with respect to said first member and with said first and second member opening generally toward said apparatus, and thereafter c. directing said chain around said second member, and thereafter d. feeding said chain to said apparatus, said chain positively received by said apparatus wherein said connected bag elements comprise bags each having supporting means adjacent the top end thereof, and wherein said feeding step comprises directing said supporting means of said bags to a receiving means of said apparatus whereby said bags are received progressively by said receiving means through said supporting means of said bags.
Claim 8
Independent Claim
143 words
A method of feeding a chain of connected bag elements to filling apparatus comprising: a. directing said chain generally upwardly to a first member, and thereafter b. directing said chain around said first member and then downwardly therefrom to a second member which is angularly disposed with respect to said first member and with said first and second member opening generally toward said apparatus, and thereafter c. directing said chain around said second member, and thereafter d. feeding said chain to said apparatus, said chain positively received by said apparatus wherein said connected bag elements comprise bags each having supporting means adjacent the top end thereof, and wherein said feeding step comprises directing said supporting means of said bags to a receiving means of said apparatus whereby said bags are received progressively by said receiving means through said supporting means of said bags.
Claim 9
Dependent Claim
13 words
The method of claim 6 wherein said first member is generally horizontally disposed.
Claim 10
Dependent Claim
17 words
The method of claim 6 wherein the angle between said first and second members is approximately 45*.
Claim 11
Dependent Claim
20 words
The method of claim 6 wherein said connected bag elements are fed to said first member from a folded pile.
Claim 12
Dependent Claim
64 words
The method of claim 6 wherein said first and second members include opposed inner and outer side portions respectively with said inner side portions defined as facing each other, said elements being directed to said outer side portion of said first member and topwise thereover and then downwardly to said outer portion of said second member and bottomwise thereunder and thereafter to said apparatus.
Claim 13
Dependent Claim
13 words
The method of claim 6 wherein said supporting means comprises open ended loops.
Claim 14
Dependent Claim
12 words
The method of claim 6 wherein said receiving means comprises a mandrel.
