Here are a few rakes I found, as well as a failed rake:

The two that are side by side were inspired by the rake that was initially a puffer on the right. That one on the right was a puffer that produced both space ships and replicators. By halving the replicator column I made the one on the left. The right one got turned into a rake when trying to contain its output. I simply extended it out a bit to demonstrate its original form.
The one at bottom (labeled 'FAILED RAKE') is a spaceship that resulted from trying to increase the period of the rake above it by lengthening the replicator column. It does output spaceships but to allow for clean up of the replicators they have to be destroyed before they can reach the back.
