Abstract
Abstract An apparatus for use in compressing and conveying scrap metal or other blocks which includes a supporting chain comprising a plurality of segment chains releasably connected to each other by connecting pieces at both ends, a open ended tubular member forming press side walls and acting as a block carrier, and a base support provided with a groove for receiving the supporting chain. The supporting chain is secured to the bottom edge of the tubular member, and the tubular member is removably mounted on the support to receive the scrap which is pressed when the tubular member is mounted on the support. Upon removal of the tubular member, the supporting chain releasably supports the pressed block.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
144 words
Apparatus for use in pressing and transporting blocks of scrap material, comprising: a tubular member (3) open at both ends thereof and acting as a block carrier; a supporting chain (9) comprising a plurality of releasably interconnected chain segments (10), said supporting chain (9) being connected to said tubular member (3); and a rigid support member (1) provided with a groove (5) for receiving said supporting chain (9), said rigid support member (1) removably receiving said tubular member (3) at one of the open ends of said tubular member to form a scrap receiving receptacle, said scrap being pressed in said formed receptacle, whereby when said tubular member (3) is removed from said rigid support member (1) after a pressing operation for transporting the pressed scrap block, said scrap block is releasably retained in said tubular member (3) by said interconnected chain segments (10).
Claim 2
Dependent Claim
144 words
Apparatus for use in pressing and transporting blocks of scrap material, comprising: a tubular member (3) open at both ends thereof and acting as a block carrier; a supporting chain (9) comprising a plurality of releasably interconnected chain segments (10), said supporting chain (9) being connected to said tubular member (3); and a rigid support member (1) provided with a groove (5) for receiving said supporting chain (9), said rigid support member (1) removably receiving said tubular member (3) at one of the open ends of said tubular member to form a scrap receiving receptacle, said scrap being pressed in said formed receptacle, whereby when said tubular member (3) is removed from said rigid support member (1) after a pressing operation for transporting the pressed scrap block, said scrap block is releasably retained in said tubular member (3) by said interconnected chain segments (10).
Claim 3
Dependent Claim
16 words
Apparatus according to claim 1 wherein said chain segments include releasable connecting pieces at ends thereof.
Claim 4
Dependent Claim
50 words
Apparatus according to claim 2 wherein said releasable connecting pieces each include a pin (22) coupled to a withdrawal means (17) for releasably retaining two ends of said chain segments (10), whereby withdrawal of sAid pin separates said chain segments to release a scrap block supported by said supporting chain.
Claim 5
Dependent Claim
26 words
Apparatus according to claim 3 wherein said withdrawal means comprises a separating line (17) carried by said tubular member (3) for selectively withdrawing said pins (22).
Claim 6
Dependent Claim
32 words
Apparatus according to claim 1 further comprising a separating line (17) carried by said tubular member (3) and interconnected to said chain segments (10) for selectively releasing said interconnected chain segments (10).
Claim 7
Dependent Claim
32 words
Apparatus according to claim 1 wherein said supporting chain (9) includes a plurality of connecting chains (25) connecting said chain segments (10) to the lower edge portion of said tubular member (3).
Claim 8
Dependent Claim
23 words
Apparatus according to claim 1 wherein said tubular member (3) includes projections (11) extending from the walls thereof for suspending said tubular member.
Claim 9
Dependent Claim
23 words
Apparatus according to claim 1 wherein said tubular member (3) is mounted on said support member (1) about a vertical longitudinal axis thereof.
