Abstract: Methods, systems and devices for protecting flooring beneath a toilet having a toilet base set over a drain pipe in the flooring, including a device and system having a tray defining a hole configured to be positioned over the drain pipe, the tray having an outside perimeter edge surrounding the hole and defining a field which extends outward from the toilet base when the toilet is positioned upon the tray, and a liquid retainer configured for placement upon the field and having a first end portion to abut a first external area of the toilet base and a second end portion to abut a second external area of the toilet base. The tray may be cut with a scissors to universally match a variety of toilet bases and is of low profile to be undetectable or nearly undetectable (concealed) to a normal casual viewer. The field is configured to receive stray liquid from the toilet crossing a seep line while a side edge perimeter of the toilet is sealed.

Abstract: A rotor link attached to a debarking cylinder. An open link is attached to the rotor link and a chain is attached to the open link. The open link must be rotated forward in the direction of rotation of the debarking cylinder so that a flat area of the rotor link is presented adjacent the open area of the open link. This makes it less likely that the link will be disengaged by random movement of the chain during a debarking operation. Thus, individual chains can be removed without removal of the attachment rod and all the chains on the cylinder. A second chain may be attached to the open link through a similar series of translational and rotational movements.
