Appeal No. 2002-1038
Application 09/122,022
Zimmerman discloses a grip-enhancing covering for non-slip
application to the handle of a baseball bat, which covering can
also be adapted for application to the handles of tennis rackets,
cricket bats, golf clubs, portable flag poles, cranks and all
kinds of tools (see page 1, lines 79 through 86). The covering A
consists of a rubber tube having a closed end and a diameter
slightly smaller than that of the bat handle to which it is to be
applied. Zimmerman teaches that
[i]n order to positively secure the tube upon the
handle I provide a special fastening means which
consists in circumferentially grooving the bat handle
adjacent the heel thereof as shown at C and providing a
circumferential lug D upon the inside of the tube
adjacent the closed end thereof. When the tube is
applied to the handle and the lug engages within the
groove it will be impossible to withdraw the same
unless cut [page 1, lines 58 through 67].
Hemming discloses a piece of cutlery composed of a blade 1
including a tang 2 about which is molded a bolster 3 having a
tail piece 4, and a hard rubber handle 6 having a bore 5 adapted
to receive the tang and bolster. According to Hemming,
[i]t will readily be seen that when the rubber handle
is brought in contact with hot water, it will both
soften and expand and lose its holding grip on the tail
piece of the bolster.
To overcome this trouble, a properly shaped tool,
not shown, is inserted in the bore 5, Figure 4, to form
the circumferential grooves 8, see also Figure 2,
larger than the bore 5. The tang 2 of the blade is
then inserted in the bore of the handle 6, and said
handle enclosed in the conventional two-part mold 9,
