be swiftly applied to anymachine tool in the shop. Numerous machine shop tools arenot equipped with a pan and pump, simply because they are usedmostly for operating on grey iron, but occasionally the ma-chine might be used on malleable iron or steel, in which casea coolant is essential for the greatest results. In such situations, theportable unit illustrated can be utilised to good benefit.It may also be employed on machines currently offered with acoolant program, which for some cause or other is out oforder. In this emergency the transportable system shown can be quickly brought into place and production will notbe interrupted. The Fulllo pump illustrated is a total, self-containedsystem, requiring practically nothing but attaching the motor cord tothe lump socket. The total height from the floor is only14 in., which pennits its being rolled under any ordinarylathe, as shown in the illustration. Provision is produced forattaching further splash boards when required. Thepump and motor are fully covered, as a result affording

Fulflo Transportable Lubricating Unit Employed with Turret Lathe ample protection from each liquids and dust. The outfitcan be used on grinding machines as w-ell as on lathes,milling machines, drill presses, gear cutters, and so forth. Thereis only 1 moving part in the pump namely, the impeller,which has no metal contact, and for that reason cannot put on outquickly. It is packed with metallic packing which willnot cut the shaft. The bearings are effectively lubricated, andsince the shaft is hardened and ground, extended, continuedservice may be expected. MULTI GRADUATED PRECISION GRINDER It has Ijeen hard in the past to machine screw threadsurfaces with the identical accuracy obtained in machiningcylindrical, flat or spherical surfaces. On account of thisfact, it has been difficult to make master thread gages and themachine illustrated was made for this objective by thePrecision &amp Thread Grinder Manufacturing Organization, Phil-adelphia, Pa. It can be used in conjunction with anymachine tool and is adaptable to a range

present, thelaunder method attached to the spitzkasten of every single flotationmachine is being rebuilt in such a manner that all middlingfroth and pulp are returned to a box directly in front ofthe first cell of the machine. The bottom of this box isbelow the bottom of the cell. This box is connected to thebottom of the 1st cell of the machine by a 6-in. suctionpipe. The pumping action of the impeller in the cell servesto return all froth and middling to the first cell of the ma-chine, generating every machine a separate and distinct unitand doing away with middling return elevators and theirnecessary upkeep. 22 Engineering and Mining Journal Vol. 108, No. 1 aiiiiiiiiiiiiiiiiiiiiii iiiiiiiii iiiiiiiiiiii inn inn mm mniinnn nmnnnmm mmnnmmnunnmnmmmnm i mninnn imni i i n mnnmnmnn i nnnmniiig I Modern day Stripping Gear in Minnesota | ^nnnmnniinnnMnniinnnnnniiMnninnniinnnnnninnnnnnMnniinninnnnniinnnininnninnnnninntnninnHnninninnnnnnnnnninnnnninniinninniinninninnnnnnnnnnnnnnnniinnnnninninnnjnnini^
