An adjustable guide bar is attached to substantialbrackets on the back of the lathe, as shown in the illustrations, Turret Attachment for Jones &. Lamson Turret Lathe cutting the taper. This slide consists of a 4J/£-in. by , which is split at the bottom and bored out to receive a3/16-in. brass bushing. The auxiliary carriage is bolteddirect to the block, being recessed to tit over a bearing on theblock 4 in. in diameter and 9/16 in. high. This bearing ismade large to provide a substantial anchorage for the car-riage. The front end of the carriage rests in a slot planedout of the turret casting. This slot is of substantial dimen-.

The auxiliary carriage itself is made from abar 4 in. by 6 in., with a boss 2 in. high at the back end forreceiving the bolt in the sliding block. The tool slide is ofordinary construction. To cut a taper on the work the guide bar at the back is setat the taper desired, the auxiliary tool carriage is placed inthe slot in the turret and the work fed out through the headof the machine to the proper distance, and the cuts takenwith the tool on the auxiliary carriage. The adjustments areeasily made and this attachment has been found very service-able.
