Under this headina we shall publish weekly notes of 80M6 of tits more promi nent home and foreign patents. This improved extension carrier for securing work to the face plate of a lathe for turning boring or other purposes consists in the construction and bar to hold the work. The bars are arranged with their longer enda project ing in opposite directions. In the longer ends of the bars are formed screw holes at right angles with the holes above named to receive the screws by pass through slots in the opposite sides of the face plate of the lathe and which are in line with each other and with the lathe center. When the car rier is used as a common extension carrier a tail is used which is made with a long head to enter one of the slots in the face plate and thus carry the work. When the carrier is used as an extension carrier on line lathe center and are screwed into the holes therein so as to hold the work back to the expanded and contracted will always be in line with the lathe center. The first and most important object of the carrier is its use as a tool for holding shafting and back to face plate of lathe by means of long screws pass ing through slots of face plate the shaft meanwhile resting on a steady rest at one end and on the live center of lathe at the other. The lathe cen ter is the governing center point. The screws are screwed up until they just tighten the shaft on its center point. It is claimed to never spring out of center when held in this manner. In this position the screws act as tails to carry the shaft around. Drills or tools of suitable shape can then be brought to bear upon end of shaft. In ordinary machine shop practice the clamp with bolts (such as is used for holding wheels in boring lathes) is put before the dog and fastened back to face plate against the dog by bolts. This extension carrier dispenses with these methodsand does its part quick ly and in a workmanlike manner. BRIDGEJohn H. Diedrichs of Richmond VaThe object of this inven t
