To those, I think that the accompanying sketcheswill furnish an idea of an inexpensive arrangementthat will do the work easily, and is so simple Uiathut little explanation is necessary. It con he usedon any modem upright drill; we use it on a 34-inch Beraent, the quick n-lurn lever forcing thefittings into position quile readily. Fig. 2 illusiraUS the device for balding the ordi-nary air-hose coupling ; the body is made of wood,to which a shank tilted lo the drill press spin-. dle or socket is attached with wood screws. Fig. J illustrates the vise for holding the hose,also made of wood, with iron hinge, screw andwheel; any ordinary railroad repair shop will haveplenty of these at command; it not, it is no greatjob lo make Ibem; the writer brought inio playthe following: For the hinge, a damper hingewas found to be all right, a wedge bolt usedfor Ihe screw, while a discarded spurk-pot fur-nished the re-juLred hand-wheel. It is operated as follows : Place the device forholding the fittings in the drill press spindle, ondinsert u coupling in the opening hi the wood, boltthe vise firmly to the platen, having the slot forthe hose just clear the edge, and also in a centralposition under the shank of the coupling, gripyour hose firmly in the vise, allowing just theamount that the fitting will take np lo extendabove the vise, ihoroiiglily grease Vbc sliiink of thefitting, and il will surprise you how easy they arcforced inIo position
