Abstract

A fusing machine utilizes a fusing electrode assembly and a ground electrode assembly suspended from the fusing electrode assembly. The fusing electrode assembly includes a lower fusing electrode shaft and an upper fusing electrode shaft. The lower fusing electrode shaft has an open end adapted to receive the upper fusing electrode shaft and a compression spring interposed between the shafts. An adjustable stop is threaded onto the upper fusing electrode shaft to limit the downward movement of the upper fusing electrode shaft. The lower fusing electrode shaft is keyed to a fusing electrode holder formed from a plurality of keyed members. The ground electrode assembly includes an adjusting mechanism, whereby the position of a ground electrode carried by the ground electrode assembly can be adjusted relative to a fusing electrode carried by the fusing electrode assembly. The fusing electrode assembly and the ground electrode assembly are mounted to a frame which is adjustably attached to a supporting structure.

Claims

1. A fusing electrode assembly, comprising a fusing electrode shaft and holding means attached to said fusing electrode shaft for releasably holding a fusing electrode, said holding means including a first holding member, which is keyed to said fusing electrode shaft, said first holding member including channels which communicate with a supply of cooling medium, and a second holding member, which is keyed to said first holding member, said second holding member including first receiving means for removably receiving said fusing electrode and second receiving means, which communicates with said first receiving means, for receiving adjusting means for adjusting the position of said fusing electrode relative to said second holding member.

2. The fusing electrode assembly according to claim 1, wherein said adjusting means includes a screw threadedly received in said second receiving means.

3. The fusing electrode assembly according to claim 2, further comprising locking means for locking said fusing electrode in place in said first receiving means.
