WHITWORTHS PATENT DVPT.EX LATHE. 



A ijaper was road from Mr. ^VIltT^voBTH, describing his new lathe. 

 It is e<ju;illy applicable for cylindrical or surface tiirninfr, or for 

 cuttin^j screws. The tools are shown as applied to cylindrical 

 tiirniiis or screw cutting. For surface turning they would he 

 l)laced at rifflit angles to the jiosition shown, and a self-acting 

 nu.tion given to the right and left hand screw. The top slide- 

 rests are both provided with comjiound slides, whereby each tool 

 m;iy be adjusted to the work independently; and wlie'n once ad- 

 justed, the right and left hand screw only is used. Not only is 



double the work performed in the same time, but in long objects 

 with a less expenditure of power, owing to the saving by the less- 

 ened ])ressure against the stay. The work done is of a superior 

 kind, there being a perfect balance of forces, and conseipientlv 

 less vibration; and fnjn; tlie increased duration of the tools, only 

 one-half the amount of error takes place. Messrs. W'hitworth 

 have five of these lathes in use in their establishment, and the 

 work produced by them is of better quality and at half the cost it 

 was formerly from the single lathe.
