Abstract
Abstract This disclosure relates to a turret lathe having full production capabilities. A turret carrying a plurality of drivable end working tools is selectively indexable and a single drive means is arranged to be coupled to and uncoupled from each drivable tool when indexed to an operative position. The spindle is arranged to be driven at turning speeds for operation with turning tools, and also at feed speeds in conjunction with the end working tools so that irregular contours, slots, indentions, etc. may be machined in the end face and also the peripheries of a workpiece. The end working tools may also perform drilling, boring and tapping operations on the workpiece as it is indexed to position.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
226 words
A lathe having a member for receiving a workpiece and a shaft for driving said member, first means for driving said shaft in a speed range for turning operations on a workpiece in said member, second means for driving said shaft at a feed speed for cutting operations on the face of a workpiece and for indexing said member to a predetermined angular position, an indexable turret adapted to receive a plurality of end working tools therein in angularly spaced relation and having axes residing essentially in a common plane, means for powering one of said end working tools when in a predetermined position with respect to said member, said turret being rotatable with respect to said powering means, coupling means supported within said turret and connected to said powering means, said coupling means being movable with respect to said powering means to connect said powering means to a tool in said turret at a predetermined angular position of said turret, means for moving said coupling means into and out of driving engagement with a tool in said predetermined angular position of said turret, means for angularly positioning said turret with respect to said member, and means for simultaneously operating said member with a workpiece therein at a feed speed while powering one of said end working tools to perform a cutting operation on the workpiece.
Claim 2
Dependent Claim
226 words
A lathe having a member for receiving a workpiece and a shaft for driving said member, first means for driving said shaft in a speed range for turning operations on a workpiece in said member, second means for driving said shaft at a feed speed for cutting operations on the face of a workpiece and for indexing said member to a predetermined angular position, an indexable turret adapted to receive a plurality of end working tools therein in angularly spaced relation and having axes residing essentially in a common plane, means for powering one of said end working tools when in a predetermined position with respect to said member, said turret being rotatable with respect to said powering means, coupling means supported within said turret and connected to said powering means, said coupling means being movable with respect to said powering means to connect said powering means to a tool in said turret at a predetermined angular position of said turret, means for moving said coupling means into and out of driving engagement with a tool in said predetermined angular position of said turret, means for angularly positioning said turret with respect to said member, and means for simultaneously operating said member with a workpiece therein at a feed speed while powering one of said end working tools to perform a cutting operation on the workpiece.
Claim 3
Dependent Claim
14 words
The lathe of claim 1, further including means for restraining rotation of said shaft.
Claim 4
Dependent Claim
18 words
The lathe of claim 1 further including means for automatically positioning said shaft to a reference angular position.
Claim 5
Dependent Claim
72 words
The lathe of claim 1 wherein said powering means includes a support member extending vertically into said turret, a rotatable tool drive shaft carried by said support member and arranged to be driven by said powering means, said turret including a spindle for each of said end working tools, said coupling means comprising a member rotatable with said tool drive shaft and longitudinally movable into and out of engagement with said spindles.
Claim 6
Dependent Claim
17 words
The lathe of claim 1 further including means for indicating the coupling states of said coupling means.
Claim 7
Dependent Claim
41 words
The lathe of claim 4 wherein said tool drive shaft carries a first gear at one end thereof, and said coupling means is splined to the other end thereof, said powering means including a second gear for driving said first gear.
Claim 8
Dependent Claim
30 words
The lathe of claim 6 wherein said coupling means and each of said spindles have splines defined thereon to establish a driving connection between said coupling member and said spindles.
Claim 9
Dependent Claim
43 words
The lathe of claim 7 further including a second shaft having an idler gear thereon in meshing engagement with said gear, said second shaft having a guide on the other end thereof, and means slidable on sAid guide for moving said coupling means.
