For instance, a hob is cut asa perfect V thread, and the Fellows cutter is finished by beingcaused to roll against the carefully trued face of an emery AMERICAN ENGINEER AND RAILROAD JOURNAL. 38 wheel with a motion simulating that of a pinion tooth against:i in. k tOOth. It is the present desire to call particular attention to themachine as now provided with an individual motor drive. Theonly special work necessary was the casting of a plate to spanthe pillow blocks of the regular driving gear to afford a sup-port for the motor, and tln> substitution of a sprocket wheelfor the com1 pulley used with bell drive. With these changesa standard form has been evolved as shown in the accompany-Ing illustration. A 5-horse power irocker-Wheeler semi-inclosed motor sup- A SERVICEABLE DESIGN OF UNIVERSAL SAW BENCH. Wnu Tilting Table. , KLUSMAN & The accompanying engraving illustrates a particularly valu-able design of universal saw bench, with tilting table, whichwill be found a most desirable and useful tool for any wood-working establishment. It has several special advantages asfollows: The great variety and the accuracy of the work itwill do; the ease and quickness with which it can be changedfrom one class of work to another, and particularly the lengthof the belt, which is longer than on any other machine of thisclass that we know of. An important feature of the design of this tool is that theframe proper and the extension carrying the countershaft arecast in one piece, which greatly simplifies the machine andalso keeps the countershaft and saw mandrel always in linewith each other; the distance from countershaft to mandrelis thus such that all belt slipping is avoided, even when doingvery heavy work. By means of the improved belt tightener,any slack can be instantly taken up by sim
