Die Schraube des Oberwagens zwingt dieses gekühlte Rad gegen den Schleifston und schneidet alle dort vorhandenen Überschläge ab, Und indem es rückwärts und vorwärts arbeitet, während der Stein weggeschnitten wird, ist es ein sehr kurzes Stück Arbeit, um alle Auswühlungen zu entfernen, die durch das Werkzeugschleifen angehoben worden sind, und es zu einem Zustand der Rundheit zu bringen, der für diese Werkzeugklasse so wünschenswert ist. Das Gerät kann in Position geklemmt und der Stein trued bis jeden Tag, oder so oft ein

. American engineer and railroad journal . is opposite that portion of thewheel which is running the highest. The screw of the uppercarriage forces this chilled wheel down against the grindstoneand cuts away any projection which may exist there, and byworking it backward and forward as the stone is cut away, itis a very short piece of work to remove all of the excrescenceswhich have been raised by the tool grinding, and bring itback to a condition of roundness that is so desirable for thisclass of tool. The apparatus may be left clamped in positionand the stone trued up every day, or as often as it may bedesired to keep it in perfect condition ; and where such a de-vice as this is available and can be used at a moments notice, it is probable that the wheel will be kept in perfect shape ;but where we depend upon the iron bar and the apprenticeattachment, the probabilities are that the stone will be allowedto become so badly out of true that it will be impossible to use itbefore any steps will be taken to bring it back iuto shape.. GRINDSTONE TRUING DEVICE. THE KINGSLAND SHOPS OF THE DELAWARE, LACKAWANNA & WESTERN RAILROAD COMPANY. We believe it is about a year ago that the Kingsland shopsof the Delaware, Lackawanna it Western Railroad Companywere destroyed bv tire. They were immediately rebuilt, but, of course, many of the older tools and special appliances, which had beendesigned in the shop for particular pieces olwork, were destroyed, and as there is no record left of themthey have not been replaced. Therefore there is little aboutthe shops to attract especial attention on the ground f itsnovelty. There are, we believe, 162 engines to be taken careof, and the floor space anil pits available for the work renderit necessary that everv inch should be utilized to (he utmostof its capacity, and even then it is difficult to i;.-t out tin- workas it is required. It is probable that before long the shopswill be enlarged and more pits added. However, there are afew little wrink
