Abstract

A ratchet tool having a radial handle operatable in either direction and adapted to be placed in a neutral position, and an axial handle which can rotate in either direction when the radial handle is in its neutral position and in the effective direction of the radial handle when the latter handle is in operating engagement with the ratchet mechanism. The radial handle contains a longitudinal shaft and a knob at the end thereof for controlling the ratchet mechanism.

Claims

1. A ratchet tool comprising a body having a bore therein, a shaft in said bore having grooves in the periphery thereof, a means for connEcting one end of said shaft to a work performing means, a member disposed around said shaft intermediate said body for rotary movement relative thereto, a handle extending radially from said member, a means having a part cooperating with said grooves to form a ratchet action therebetween, a shaft extending longitudinally through said handle and being connected at one end to said part, a spring urging said part into engagement with said first-mentioned shaft, a knob disposed at the outer end of said second-mentioned shaft for rotating the latter shaft and said part to reversed operating positions and to an inoperative position, spaced slots disposed at the end of said radial handle at 90 degrees to one another for receiving a portion of said knob, one of said slots being of less depth than the other of said slots for retaining said part in its inoperative position, and an axial handle connected to said first mentioned shaft and rotatable therewith for turning said work performing means.

2. A ratchet tool as defined in claim 1 in which said radial handle consists of a tubular shaped member.

3. A ratchet tool as defined in claim 1 in which said grooves are longitudinally arranged around the periphery of said first mentioned shaft.

4. A ratchet tool as defined in claim 1 in which said part has a beveled edge for seating in said grooves.
