(under subclass 519) Support wherein the staff receiving means includes means to grip and/or to align the staff therein. This and the indented subclasses involve, predominantly, structure for supporting a Christmas tree.
(1) Note. A cylinder with a closed bottom (i.e., a socket) is not a means for this subclass unless the respective diameters of the cylinder and the staff are so related as to necessarily result in a retaining or centering function; in the absence of such a relationship, the structure is in
subclass 519 above. On the other hand, the staff receiving means of this subclass may comprise only an up-standing pin which either is driven into the bottom of the staff or else is received in a complementarily-sized bore formed in the bottom of the staff.
