Abstract
Abstract A handle for a rotary hand tool of the reversible ratchet type includes a ratchet mechanism, an elongated generally cylindrical shell mounting the ratchet mechanism adjacent the forward end thereof and having a pair of outwardly projecting retaining lugs, a cylindrical sleeve mounted on the shell to enclose the ratchet mechanism and extend longitudinally along the shell beyond the retaining lugs, said sleeve having an elongated axially extending slot and a pair of side apertures on opposite sides of the slot for receiving the lugs and locking the sleeve on the shell; and a hand grip mounted by an interference fit on the rearward end of the shell, said hand grip having a tubular extension forming a hoop circumscribing the sleeve and preventing expansion of the sleeve along the slot and removal of the lugs from the apertures.

Claim 1
Independent Claim
143 words
In a handle for a rotary hand tool of the reversible ratchet type, the combination including a ratchet mechanism; an elongated generally cylindrical shell mounting said ratchet mechanism adjacent one end thereof and having an outwardly projecting retaining lug intermediate the ends thereof; a cylindrical sleeve mounted on said one end of said shell to enclose said mechanism and extending longitudinally along said shell beyond said retaining lug, said sleeve having an elongated axially extending slot and a side aperture adjacent said slot for receiving said lug and locking said sleeve on said shell; and a hand grip mounted by an interference fit on the end of said shell opposite said one end, said hand grip having a tubular extension forming a hoop circumscribing said sleeve and preventing expansion of said sleeve along said slot and removal of said lug from said aperture.
Claim 2
Dependent Claim
