The carriage has powercross feed and the rate is indicated on the index platemounted over the gear box. The direction of feed can bechan<Ted through a reverse lever mounted in a supplementarygearcase at the headstock end of tlie lathe. All operatinghandles are conveniently located. The carriage has a comi)Ound rest so arranged that it canbe changed to either a four sided turret toolpost, combined front and rear tool rest or plain rest, without any additionalfitting. The apron is of the douJjle plate type with the twohalvcs in contact, thus forming a box section of strength and. Adams Short-Cut Lathe rigidity. Each lathe is supplied with an oil pan bed of suf-ficient size to prevent any cutting compound getting on thefloor. Universal Shaper With Unit Gear Box THE 24-in. universal shaping machine described in thisarticle is made by the Potter & Johnston MachineCompany, Pawtucket, R. I., and particular attentionis called to the gear box, which is a unit within the baseof the machine. All the universal features necessary for dieand tool work have teen incorporated in the machine, whichis at the same time well adapted for general manufacturingpurposes or repair shop service. All control handles are onthe right hand side of the shaper. A hea\^- column, of correct design to withstand all ordi-nary strains, is securely fastened to the base of the total length of the base is 34 in. A large gear givesreciprocating motion to the ram by means of a wrist pincarried in a disk set eccentric in the gear. A graduateddial on the outsi
